(1) This Registration Statement relates to shares of Class A common stock, no
    par value, of the Registrant ("AmerUs Common Stock") to be issued in
    connection with the Merger upon conversion of shares of common stock, no
    par value, of AmVestors ("AmVestors Common Stock"), or issuable upon
    exercise of outstanding warrants and options being assumed by the
    Registrant in connection with the Merger, as well as public reofferings or
    resales of certain of such shares.

(2) Represents the number of AmerUs Common Stock issuable in connection with 
    the Merger, determined on the basis of an assumed exchange ratio of 
    0.7407 shares of AmerUs Common Stock for each outstanding share of 
    AmVestors Common Stock (including shares issuable upon exercise of 
    outstanding warrants and options of AmVestors being assumed by the 
    Registrant in connection with the Merger), plus additional shares of 
    AmerUs Common Stock issuable under certain circumstances as described in 
    the Merger Agreement.

(3) The registration fee has been computed pursuant to Rules 457(c) and 
    457(f)(1) under the Securities Act of 1933, as amended (the "Securities 
    Act"), based on $20.47, the average of the high and low prices per share 
    as reported on the New York Stock Exchange Composite Tape for AmVestors 
    Common Stock on November 5, 1997, multiplied by 19,760,578, the maximum 
    number of shares of AmVestors Common Stock convertible in connection with 
    the Merger. Pursuant to Rule 457(b) under the Securities Act, $57,158.39 
    of the fee was paid previously in accordance with Exchange Act Rules 
    14a-6(i)(1) and 0-11. This fee has been calculated pursuant to Section 
    6(b) of the Securities Act, as one thirty-third of one percent of 
    $404,499,031.60.

THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATES AS MAY BE
NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL FILE A FURTHER
AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION STATEMENT SHALL
THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a), OF THE SECURITIES
ACT OF 1933 OR UNTIL THIS REGISTRATION STATEMENT SHALL BECOME EFFECTIVE ON SUCH

                    [AMERUS LIFE HOLDINGS, INC. LETTERHEAD]
 
                  STOCK ISSUANCE--YOUR VOTE IS VERY IMPORTANT
 
Dear Shareholder:
 
    You are cordially invited to attend a Special Meeting of Shareholders of
AmerUs Life Holdings, Inc. to be held on December 18, 1997, at the offices of
AmerUs Life Insurance Company at 611 Fifth Avenue, Des Moines, Iowa. The meeting
will start at 10:00 a.m., local time.
 
    At this important meeting, you will be asked to approve a stock issuance by
AmerUs in connection with a proposed acquisition of AmVestors Financial
Corporation by AmerUs under a merger agreement dated September 19, 1997. The
stock issuance you are being asked to approve is required to complete the
merger. The full text of the merger agreement is included at the back of this
document as Annex I.
 
    Your Board of Directors believes that the merger will benefit AmerUs in a
number of ways. Among other things, the merger, along with the recent
acquisition of Delta, will significantly increase AmerUs' position in the asset
accumulation business. This business involves securing and actively managing
policyholders' funds through insurance and annuity products. The merger also
provides opportunities presented by the combined companies' increased resources,
such as the potential for cross-selling products in the multiple distribution
systems and the expense reductions available from the combining of similar
functions. YOUR BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF AMERUS
APPROVE THE STOCK ISSUANCE AT THE SPECIAL MEETING SO THAT THE MERGER MAY BE
COMPLETED.
 
    If the merger is completed, AmerUs expects to issue shares of its Class A
common stock (generally intended to be valued at not less than $20) for each
share of AmVestors common stock outstanding immediately prior to completion of
the merger, as illustrated in the table on page 1 of this document.
 
    Based on assumptions described in this document, the stockholders of
AmVestors are expected to receive between approximately 33.3% and 35.5% of the
total outstanding shares of common stock of AmerUs following the merger.
 
    Your Board has received a written opinion from Donaldson, Lufkin & Jenrette
Securities Corporation, its financial advisor, dated September 19, 1997, to the
effect that as of such date the exchange ratio in the merger was fair from a
financial point of view to AmerUs.
 
    The Merger will not be completed unless the issuance of shares by AmerUs is
approved by the affirmative vote of a majority of votes cast at the Special
Meeting, assuming a quorum is present. American Mutual Holding Company
beneficially owns shares of AmerUs common stock sufficient to approve the
issuance of shares. AmerUs has been advised that the Board of Directors of
American Mutual Holding Company has passed a resolution to cause all such shares
to be voted in favor of the proposed stock issuance.
 
    Whether or not you plan to attend the Special Meeting, please take the time
to vote by completing and returning the enclosed proxy card to us. A postage
paid envelope is enclosed for your convenience. If you sign, date and return
your proxy card without indicating how you want to vote, your proxy will be
counted as a vote in favor of the stock issuance. Even if you plan to attend the
meeting, please complete and return your proxy.
 
    This document provides you with detailed information about the proposed
merger and related stock issuance. We encourage you to read this entire document
carefully.
 
Sincerely,
- ---------------------------------------

                  [AMVESTORS FINANCIAL CORPORATION LETTERHEAD]
 
Dear Stockholder:
 
    You are cordially invited to attend a Special Meeting of Stockholders of
AmVestors Financial Corporation to be held on December 18, 1997, at the Kansas
City Airport Marriott, 775 Brasilia Street, Kansas City, Missouri. The meeting
will start at 10:00 a.m., local time.
 
    At this important meeting, you will be asked to approve a merger agreement
between AmVestors Financial Corporation and AmerUs Life Holdings, Inc. The
merger agreement was executed on September 19, 1997, and provides for AmerUs'
acquisition of AmVestors. If the merger agreement is approved and certain other
conditions are met, AmVestors will become a subsidiary of AmerUs Life Holdings,
Inc. and AmVestors stockholders will become AmerUs shareholders. The full text
of the merger agreement is included at the back of this document as Annex I.
 
    If the merger is completed, AmVestors stockholders will receive, for each
share of AmVestors common stock, between .6724 shares and .7407 shares of AmerUs
Class A common stock (generally intended to value each share of AmVestors common
stock at not less than $20.00), depending on the average last reported sales
price of the AmerUs Class A common stock on the Nasdaq National Market for a
specified period prior to closing. THE CALCULATION OF THE AMOUNT RECEIVABLE IS
SET FORTH ON PAGE 1 OF THIS DOCUMENT. If such average AmerUs trading price is
less than $27.00 per share (thereby resulting in a value of less than $20.00 per
share of AmVestors common stock), AmVestors may (but is not obligated to)
terminate the merger agreement unless AmerUs adjusts the exchange ratio to
achieve a value of $20.00 per share of AmVestors common stock.
 
    AmerUs also has a Class B common stock, all of which is owned by AmerUs
Group. Under the AmerUs Charter, holders of AmerUs Class B common stock have the
right to cast a majority of the votes on any matters submitted to shareholders,
except where the AmerUs Charter or Iowa law require separate class votes.
 
    We expect that the stockholders of AmVestors will receive between
approximately 33.3% and 35.5% of the total outstanding shares of common stock
(representing approximately 24.2% to 25.4% of the total voting power) of AmerUs
after the merger.
 
    Your Board has received a written opinion from Goldman, Sachs & Co., its
financial advisor, dated September 19, 1997, to the effect that as of such date
the exchange ratio in the merger agreement was fair from a financial point of
view to holders of AmVestors common stock.
    Your Board of Directors unanimously approved the merger agreement and
believes that the merger with AmerUs is in the best interests of AmVestors and
its stockholders. The Board unanimously recommends that you approve the merger
agreement at the Special Meeting so that the merger may be completed.
 
    Whether or not you plan to attend the Special Meeting, please take the time
to vote by completing and returning the enclosed proxy card to us. A postage
paid envelope is enclosed for your convenience. If you sign, date and return
your proxy card without indicating how you want to vote, your proxy will be
counted as a vote in favor of the merger agreement. If you fail to return a
proxy, or fail to vote at the meeting or abstain this will have the effect of a
vote against the merger. Even if you plan to attend the meeting, please complete
and return your proxy.
 
    Pursuant to Kansas law, holders of AmVestors common stock do not have
appraisal rights with respect to the merger.
 
    This document provides you with detailed information about the proposed
merger and related stock issuance. In addition, you may obtain information about
AmVestors from documents that AmVestors has filed with the Securities and
Exchange Commission. We encourage you to read this entire document carefully.
 
Sincerely,
- --------------------------------------------

CONFIDENTIAL, FOR USE
OF THE COMMISSION ONLY
 
                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
 
    Notice is hereby given that a Special Meeting of Shareholders of AmerUs Life
Holdings, Inc. will be held on December 18, 1997, at the offices of AmerUs Life
Insurance Company at 611 Fifth Avenue, Des Moines, Iowa. The meeting will start
at 10:00 a.m., local time.
 
    The Special Meeting will be held for the following purposes:
 
    1.  To consider and vote upon a proposal to issue shares of Class A common
stock, no par value, of AmerUs in accordance with a merger agreement which
provides for the acquisition of AmVestors Financial Corporation.
 
    2.  To consider and act upon such other business as may properly come before
the Special Meeting or any adjournment or postponement thereof.
 
    If the merger is completed, AmerUs will issue shares of its Class A common
stock (generally intended to be valued at not less than $20) for each share of
AmVestors common stock outstanding immediately prior to completion of the
merger, as illustrated in the table on page 1 of this document.
 
    Based upon the assumptions described in this document, the number of shares
of AmerUs Class A common stock issued in the merger is expected to be between
approximately 11.6 million and 12.8 million shares, (excluding shares underlying
certain convertible securities), and except as provided in the next sentence,
should not exceed 14.7 million shares. If a specified average trading price of
AmerUs Class A common stock during the period defined in the merger agreement is
less than $27, AmVestors may (but is not required to) terminate the merger
agreement unless AmerUs agrees to provide additional shares of AmerUs Class A
common stock necessary to achieve a value of $20 per share of AmVestors common
stock. If the stock issuance is approved and if AmVestors seeks to terminate the
merger agreement in accordance with the prior sentence, your Board of Directors
may increase the shares being issued in excess of the number stated above in
order to achieve the value of $20 per share of AmerUs Class A common stock. The
exact number of shares to be issued in the merger is not likely to be known by
you at the time of the Special Meeting.
 
    Only holders of AmerUs common stock of record as of the close of business on
November 5, 1997 (the "Record Date") are entitled to notice of and to vote at
the Special Meeting or any adjournment or postponement thereof.
 
    The Merger will not be completed unless the issuance of shares by AmerUs is
approved by the affirmative vote of a majority of votes cast at the Special
Meeting, assuming a quorum is present. American Mutual Holding Company
beneficially owns shares of AmerUs common stock sufficient to approve the
issuance of shares. AmerUs has been advised that the Board of Directors of
American Mutual Holding Company has passed a resolution to cause all such shares
to be voted in favor of the proposed stock issuance.
 
    Whether or not you plan to be present at the Special Meeting, please
complete, date, and sign the enclosed proxy and return it in the enclosed
envelope. If you plan to attend the meeting, please mark the appropriate space
on the enclosed proxy.

             WHAT AMVESTORS STOCKHOLDERS WILL RECEIVE IN THE MERGER
 
    The number of shares of AmerUs Class A common stock into which one share of
AmVestors common stock would be converted in the merger is referred to in this
document as the "merger consideration" or the "exchange ratio". In the merger,
AmerUs expects to issue between 0.6724 and 0.7407 shares of its Class A common
stock for each share of AmVestors common stock held by AmVestors stockholders
immediately before completion of the merger, determined as follows:
 
    - if the average last reported sales price for a share of AmerUs Class A
      common stock over the 20 trading day period ending on the tenth trading
      day prior to completion of the merger (the "average trading price") is
      greater than or equal to $27.00 and less than or equal to $29.75, each
      AmVestors share will be converted into a fraction of a share of AmerUs
      Class A common stock equal to $20.00 divided by such average trading
      price;
 
    - if such average trading price is more than $29.75, each AmVestors share
      will be converted into 0.6724 shares of AmerUs Class A common stock;
 
    - if such average trading price is less than $27.00, each AmVestors share
      will be converted into 0.7407 shares of AmerUs Class A common stock;
 
    - if such average trading price is less than $27.00, the AmVestors Board may
      terminate the Merger Agreement unless AmerUs adjusts the exchange ratio to
      the fraction of a share of AmerUs Class A Common Stock equal to $20.00
      divided by such AmerUs average trading price (resulting in a $20.00 per
      share value for AmVestors common stock). The AmVestors Board is not
      required to exercise this termination right and does not currently intend
      to resolicit stockholder approval should it decide not to exercise such
      right. THEREFORE, AMVESTORS STOCKHOLDERS COULD RECEIVE CONSIDERATION IN
      THE MERGER VALUING THEIR SHARES OF AMVESTORS COMMON STOCK AT LESS THAN
      $20.00 PER SHARE.
 
    The actual value of the shares of AmerUs Class A common stock issued in the
merger cannot be determined at this time since it is based upon the market price
of such shares at the time the merger is completed. The last reported sales
price on November 11, 1997 for AmerUs shares as reported by Nasdaq was
$31 11/16. If the average trading price were $31 11/16, the exchange ratio would
be 0.6724 with a market value of 21.31. The closing price for AmVestors shares
as reported on the New York Stock Exchange composite tape on November 11, 1997
was $20 3/4. You should obtain current market prices for these stocks. For
information concerning the exchange ratio based on the anticipated closing date
of December 19, 1997, please call 1-800-301-8755 after the projected price
measuring date of December 5, 1997.
 
EXAMPLE: If you hold 100 shares of AmVestors common stock (worth approximately
         $2,075 at $20 3/4 per share), the number of shares of AmerUs Class A
         common stock you would receive in the merger would vary depending on
         the AmerUs average trading price, for example:

    adjusts the exchange ratio to achieve a $20.00 per share value for AmVestors
    Common Stock.
 
    If the stock issuance is approved, the AmerUs Board would have the authority
to increase the number of shares being issued to achieve the value of $20 per
share. AmerUs shareholders should note that the exact number of shares to be
issued in the merger is not likely to be known at the time of the Special
Meetings.

         QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE STOCK ISSUANCE
 
Q: WHY ARE THE TWO COMPANIES PROPOSING THE MERGER?
 
A:  AmerUs and AmVestors provide a variety of life insurance and annuity
    products. The merger would give shareholders a stake in a combined
    enterprise with greater financial resources and increased product and
    geographic diversification. Management of AmerUs and AmVestors believe the
    two companies have compatible business and operating strategies. The merger
    would also provide an opportunity for improved efficiency and reduced
    expenses.
 
Q: WHAT WILL HAPPEN TO MY DIVIDENDS?
 
A:  AmVestors currently pays a quarterly dividend of $0.03 per share. AmerUs
    currently pays a quarterly dividend of $0.10 per share. In the merger,
    AmVestors stockholders will receive fewer shares of AmerUs than they own of
    AmVestors. However, if the current AmerUs dividend rate is maintained, an
    AmVestors stockholder who retains shares issued in the merger will receive a
    substantial increase in quarterly dividends. The ability of AmerUs, like
    AmVestors, to pay dividends is dependent upon the receipt of dividends and
    other funds from its insurance subsidiaries (see "RISK FACTORS--Holding
    Company Structure; Limitation on Dividends") and upon compliance with
    certain credit agreements (see "Additional Information Regarding
    AmerUs--Management's Discussion and Analysis of Results of Operations and
    Financial Condition of AmerUs--Liquidity and Capital Resources").
 
Q: WILL I OWE ANY FEDERAL INCOME TAX AS A RESULT OF THE MERGER?
 
A:  In general, you will not recognize any gain or loss for U.S. federal income
    tax purposes as a result of the merger, except to the extent of any gain
    with respect to any cash payment you receive instead of any fractional share
    of AmerUs Class A common stock.
 
Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?
 
A:  The companies are working to complete the merger as soon as possible. In
    addition to shareholder approvals, certain regulatory approvals must be
    obtained and other conditions met. The merger is expected to be completed as
    soon as possible following approval of all merger-related proposals at the
    AmerUs and AmVestors special shareholder meetings.
 
Q: WHAT DO I NEED TO DO NOW?
 
A:  Just mail your signed proxy card in the enclosed return envelope as soon as
    possible so that your shares will be represented at your special meeting.
    The AmVestors and AmerUs special meetings will take place on December 18,
    1997.
 
Q: SHOULD I SEND IN MY STOCK CERTIFICATE NOW?
 
A:  No. If the merger is completed, we will send AmVestors stockholders written
    instructions for exchanging their stock certificates. AmerUs shareholders
    will keep their certificates.
 
Q: WHO CAN HELP ANSWER QUESTIONS?
 
A:  If you have more questions about the merger you should contact:

    AmerUs Life Holdings, Inc. ("AMERUS") is an insurance holding company
engaged in the business of marketing, underwriting and distributing a broad
range of individual life insurance and annuity products in 49 states and the
District of Columbia. AmerUs is part of the nation's first mutual insurance
holding company structure, under which American Mutual Holding Company ("AMHC")
is the parent corporation of AmerUs. As of November 5, 1997, the record date for
the AmerUs special meeting, AMHC beneficially owned approximately 72% of the
common stock of AmerUs.
 
    The principal subsidiaries of AmerUs are AmerUs Life Insurance Company and
Delta Life Corporation. AmerUs acquired Delta Life Corporation on October 23,
1997 for $162.9 million in cash. Delta specializes in the sale of individual
single and flexible premium deferred annuities. As of June 30, 1997, Delta had
approximately 52,000 annuity contracts outstanding, assets of $2.0 billion,

billion. AmerUs also owns a 34% interest in a joint venture with Ameritas Life
Insurance Corp., through which AmerUs markets variable life insurance and
variable annuity products.

                  AMERUS OWNERSHIP STRUCTURE AFTER THE MERGER
 
    The following chart illustrates the general organization of AmerUs
immediately following completion of the Merger, assuming the Merger
Consideration is 0.6724 shares of AmerUs Class A Common Stock and all warrants
and options to purchase AmVestors Common Stock are rolled over into warrants and
options to purchase shares of AmerUs Class A Common Stock. The percentages shown
do not include shares of AmerUs Class A Common Stock which may be issued upon
exercise of warrants and options following the Merger. In addition, the
percentage of AmerUs Common Stock owned by AmerUs Group would be increased if,
as expected, AmerUs Group acquires additional shares of AmVestors Common Stock
prior to completion of the Merger.
 
    AmerUs has two classes of common stock. In the Merger, AmVestor stockholders
would receive AmerUs Class A common stock, the same class held by other public
shareholders. AMHC beneficially owns all outstanding shares of AmerUs Class B
common stock. Under the AmerUs Charter, shares of AmerUs Class B common stock
carry with them the right to cast a number of votes generally intended to ensure
that AMHC has the right to cast at least 50.1% of the votes entitled to be cast
with respect to capital stock of AmerUs. See "DESCRIPTION OF AMERUS CAPITAL
STOCK." See "ADDITIONAL INFORMATION REGARDING AMERUS--Business--Certain
Transactions and Relationships" for information concerning the relationship
between AMHC, AmerUs Group and AmerUs.

<PAGE>
                             REASONS FOR THE MERGER
 
    For AmerUs, the Merger is consistent with its strategy of seeking growth
through strategic acquisitions and alliances. In particular, the Merger will
expand the presence of AmerUs in the rapidly growing asset accumulation market.
In addition, the Merger will enhance the breadth and diversity of its
distribution networks and is expected to permit cross-selling of products in
multiple distribution systems and cost savings from combining similar functions,
including anticipated expense savings and operation efficiencies estimated at
between $6-8 million (pre-tax) during 1998, with additional savings expected
thereafter.
 
    For AmVestors, the Merger presents an opportunity for its stockholders to
participate, through a tax-free reorganization, in a combined company with
greater financial resources, diversification and ability to compete in a
consolidating life insurance/annuity products industry, and also an opportunity
to realize a premium over historic market prices for their shares.
 
                        RECOMMENDATIONS TO SHAREHOLDERS
 
    The Board of Directors of AmerUs unanimously recommends that the
shareholders of AmerUs approve the proposed stock issuance at the AmerUs Special
Meeting so that the Merger may be completed.
 
    The Board of Directors of AmVestors unanimously recommends that the
stockholders of AmVestors approve the Merger Agreement at the AmVestors Special
Meeting so that the Merger may be completed.
 
                                   THE MERGER
 
    In the Merger, AmVestors will merge with a subsidiary of AmerUs and become a
subsidiary of AmerUs. The former stockholders of AmVestors will become
shareholders of AmerUs. For a description of what AmVestors stockholders will
receive in the Merger, see page 1 of this document. Based on the current market
price for AmerUs Class A common stock (a $31 11/16 per share last reported sales
price as of the trading day immediately preceding the date of this Joint Proxy
Statement/Prospectus), the aggregate dollar value of the AmerUs Class A common
stock to be paid by AmerUs in connection with the Merger to holders of AmVestors
common stock including holders of existing warrants and options to acquire
AmVestors common stock, would be approximately $421 million. The actual value
will depend upon market prices at the time of the Closing. We encourage you to
read the Merger Agreement because it is the legal document that governs the
Merger and the Stock Issuance.
 
                           OWNERSHIP AFTER THE MERGER
 
    Based on the assumptions described in this document, we expect that
following the Merger the stockholders of AmVestors would receive between
approximately 33.3% and 35.5% of the total outstanding shares of common stock
(representing approximately 24.2% to 25.4% of the total voting power) of AmerUs.
Based upon its ownership interest as of November 5, 1997, immediately after
completion of the Merger AMHC would beneficially own a minimum of between 46.6%
and 48.2% of the outstanding common stock of AmerUs. In any event, AMHC would
have the right to cast at least a majority of the votes entitled to be cast at a
meeting of shareholders except where the AmerUs Charter or Iowa law require
separate class votes.
 
                      CONDITIONS TO COMPLETING THE MERGER
 
    Completion of the Merger depends upon satisfaction of a number of
conditions, including the following:
 
        (1) approval by shareholders of AmerUs of the issuance of Class A common
    stock in the Merger;
 
        (2) approval by stockholders of AmVestors of the Merger Agreement;
 
        (3) receipt of all required regulatory approvals, including from
    insurance regulators for the states of Iowa, Kansas and Florida;
 
        (4) absence of any governmental or legal actions prohibiting completion
    of the Merger;
 
        (5) receipt of opinions from legal advisors to AmerUs and AmVestors
    relating to the U.S. federal income tax treatment of the Merger described
    below; and
 
        (6) absence of events between the date of the Merger Agreement and
    completion of the Merger which have or could have a material adverse effect
    (as defined in the Merger Agreement) on AmerUs or AmVestors.
 
                                       5
<PAGE>
    Certain of the conditions may be waived by the party entitled to assert it.
AmVestors intends to resolicit shareholder approval for any waiver of the six
conditions referred to above. After consultation with AmerUs Group, the
controlling shareholder of AmerUs, the AmerUs Board will determine whether to
resolicit shareholder approval for any waiver of any of such conditions and in
any event will make appropriate disclosures. However, AmerUs will not waive
receipt of the opinions relating to the U.S. federal income tax treatment of the
Merger.
 
                      TERMINATION OF THE MERGER AGREEMENT
 
    The Merger Agreement may be terminated at any time by agreement of AmerUs
and AmVestors. In addition, either AmerUs or AmVestors may terminate the Merger
Agreement in certain circumstances including if:
 
        (1) completion of the Merger has not occurred by June 30, 1998 (subject
    to a 90 day extension period if the failure to complete the Merger is due to
    an inability to obtain the required governmental approvals); or
 
        (2) the other party breaches its representations, warranties or
    obligations under the Merger Agreement and that breach cannot be remedied;
    or
 
        (3) the shareholders of AmerUs do not approve the issuance of Class A
    common stock in the Merger or the stockholders of AmVestors do not approve
    the Merger Agreement.
 
    In addition, AmerUs may terminate the Merger Agreement in certain
circumstances including if:
 
        (1) the AmVestors Board withdraws
    its recommendation to stockholders that
    the Merger Agreement be adopted and approved; or
 
        (2) the AmVestors Board recommends to stockholders a tender offer,
    merger or similar proposal made by a third party.
 
    AmVestors may terminate the Merger Agreement in certain circumstances
including if:
 
        (1) the AmVestors Board determines that termination is necessary to
    satisfy the Board's fiduciary duties in order to enter into a superior
    transaction with another party; or
        (2) the average trading price for AmerUs Class A common stock is less
    than $27 per share (and AmerUs does not agree to provide additional shares
    to achieve a value of $20 per share of AmVestors common stock).
 
    If the Merger Agreement is terminated, under certain circumstances AmVestors
may be obligated to pay AmerUs $10.8 million, plus certain expenses of AmerUs
associated with the proposed transaction.
 
                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
    We have structured the Merger so that it will qualify as a reorganization
for U.S. federal income tax purposes. Assuming that the Merger qualifies as a
reorganization, neither AmerUs, AmVestors, nor their stockholders will recognize
any gain or loss for U.S. federal income tax purposes in the Merger (except for
any gain recognized with respect to the receipt of any cash payment received in
lieu of a fractional share of AmerUs Class A common stock). We have conditioned
the Merger on our receipt of legal opinions that the Merger will be treated as a
reorganization for U.S. federal income tax purposes. No ruling has been (or will
be) sought from the Internal Revenue Service as to the U.S. federal income tax
consequences of the Merger.
 
    TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU MAY DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN
TAX ADVISOR TO UNDERSTAND FULLY THE TAX CONSEQUENCES OF THE MERGER TO YOU.
 
                            COMPARATIVE STOCK PRICES
 
    AmerUs Class A common stock is listed and traded on the Nasdaq National
Market ("NASDAQ") under the symbol "AMRS." AmVestors common stock is listed and
traded on the New York Stock Exchange under the symbol "AMV." On September 19,
1997, the last trading day ending prior to the public announcement of the
proposed Merger, the last reported sales price of AmerUs Class A common stock
quoted on the Nasdaq was $28 3/4 and the closing price of AmVestors common stock
on the New York Stock
 
                                       6
<PAGE>
Exchange was $24 15/16. On November 11, 1997, the last reported sales price of
AmerUs Class A common stock quoted on Nasdaq was $31 11/16. On the same date,
the closing price of AmVestors common stock reported on the New York Stock
Exchange composite tape was $20 3/4.
 
    AmerUs has agreed to file an application to list on Nasdaq the shares of
AmerUs Class A common stock to be issued in the Merger.
 
                              ACCOUNTING TREATMENT
 
    The Merger will be accounted for under the "purchase" method of accounting.
This means that the assets and liabilities of AmVestors will be recorded on
AmerUs' books at their fair market values. The excess of the Merger
consideration over the net fair market value of AmVestors' assets and
liabilities will be recorded as goodwill. After the Merger, the assets,
liabilities and results of operations of the two companies will be consolidated.
 
                         REQUIRED REGULATORY APPROVALS
 
    The Hart-Scott-Rodino Act prohibits AmerUs and AmVestors from completing the
Merger until each has furnished certain information to the Antitrust Division of
the Department of Justice and the Federal Trade Commission ("FTC") and a
required waiting period has expired. AmerUs and AmVestors each filed the
required notification and report forms with the Antitrust Division and the FTC.
The required waiting period is scheduled to expire on December 10, 1997
(assuming no request for additional information is received).
 
    In addition, the issuance of AmerUs stock in the Merger will require
approval of insurance regulatory authorities in Iowa. Completion of the Merger
will require approval by regulatory authorities in the states of Kansas and
Florida.
 
                             NO DISSENTERS' RIGHTS
 
    Neither holders of AmerUs stock or AmVestors stock may demand appraisal of
or receive appraisal payments for their shares in connection with the Merger or
the stock issuance.
 
               CERTAIN TRANSACTIONS/INTERESTS OF CERTAIN PERSONS
 
    In considering the recommendations of the AmVestors' Board, stockholders of
AmVestors should be aware that members of its management will receive benefits
as a result of the Merger that will be in addition to benefits received by its
stockholders generally. Among other things, certain directors or executive
officers of AmVestors may become employed by AmerUs or receive incentive and/or
severance payments. Mr. Ralph W. Laster, Jr., the Chairman and Chief Executive
Officer of AmVestors, will be appointed to the AmerUs Board and Mr. Mark V.
Heitz, President and General Counsel of AmVestors, has entered into an
employment agreement with AmerUs to serve as the President of AmVestors (as the
surviving corporation in the Merger). Certain executive officers and directors
of AmVestors also may receive cash payments or shares of AmerUs Class A common
stock on account of stock options held by them relating to the purchase of
AmVestors common stock. Mr. Laster would receive approximately $2 million if he
elects to cash out his AmVestors options, $2.15 million on payment of incentive
arrangements and $1.69 million on payment of severance compensation as a result
of the Merger.
 
                 AMVESTORS REDEMPTION OF CONVERTIBLE DEBENTURES
 
    As part of the Merger, AmVestors agreed to redeem its outstanding
convertible debentures. On or before November 7, 1997, the outstanding
debentures were converted into approximately 3.8 million shares of AmVestors
common stock. Holders of such shares on the AmVestors Meeting Record Date are
entitled to vote at the AmVestors Special Meeting.
 
                        COMPARISON OF SHAREHOLDER RIGHTS
 
    After the Merger, the voting rights of the former stockholders of AmVestors
will differ in certain important respects once the Merger is completed and they
become shareholders of AmerUs. For example, under Iowa law and the AmerUs
Charter, AMHC will retain the right to cast at least a majority of the votes
entitled to be cast at a meeting of AmerUs shareholders, even if AMHC does not
own a majority of the outstanding shares of the AmerUs common
 
                                       7
<PAGE>
stock, except where the AmerUs Charter or Iowa law require separate class votes.
In addition, the former stockholders of AmVestors will not be entitled to
cumulative voting in the election of members of the Board of Directors of
AmerUs. A more extensive discussion is set forth in the body of this document.
 
                         OPINIONS OF FINANCIAL ADVISORS
 
    In deciding to approve the Merger Agreement, among the factors that the
AmerUs Board considered was the opinion of its financial advisor, Donaldson,
Lufkin & Jenrette Securities Corporation ("DLJ"), to the effect that as of
September 19, 1997 the exchange ratio provided for in the Merger Agreement was
fair from a financial point of view to AmerUs. The full text of DLJ's written
opinion, which sets forth assumptions made and limitations on the review
undertaken by DLJ, is included at the back of this document as Annex II. DLJ's
opinion was provided for the information and assistance of the AmerUs Board and
is not a recommendation as to how AmerUs shareholders should vote at the AmerUs
Special Meeting. Payment of a substantial amount of DLJ's fees is contingent
upon consummation of a transaction, such as the Merger. SHAREHOLDERS OF AMERUS
ARE URGED TO, AND SHOULD, READ DLJ'S OPINION IN ITS ENTIRETY.
 
    Similarly, in deciding to approve the Merger Agreement, one of the factors
that the AmVestors Board considered was the opinion of its financial advisor,
Goldman, Sachs & Co. ("GOLDMAN SACHS"), to the effect that as of September 19,
1997 the exchange ratio provided for in the Merger Agreement was fair from a
financial point of view to the holders of AmVestors common stock. The full text
of Goldman Sachs' written opinion, which sets forth assumptions made and
limitations on the review undertaken by Goldman Sachs, is included at the back
of this document as Annex III. Goldman Sachs' opinion was provided for the
information and assistance of the AmVestors Board in connection with its
consideration of the transaction contemplated by the Merger Agreement and is not
a recommendation as to how any holder of AmVestors common stock should vote at
the AmVestors Special Meeting. Payment of a substantial amount of Goldman Sachs'
fees is contingent upon consummation of a transaction, such as the Merger.
STOCKHOLDERS OF AMVESTORS ARE URGED TO, AND SHOULD, READ GOLDMAN SACHS' OPINION
IN ITS ENTIRETY.
 
                                  RISK FACTORS
 
    In considering whether to approve the proposals presented at the respective
Special Meetings of AmerUs and AmVestors, shareholders of AmerUs and
stockholders of AmVestors should carefully consider the risks associated with
the Merger and with ownership of AmerUs shares following the Merger. These risks
are described in detail in the section entitled "RISK FACTORS" which follows
this Summary.

    The following table sets forth selected unaudited pro forma combined
financial data (the "SELECTED PRO FORMA DATA"). The Selected Pro Forma Data are
presented to reflect the effects of the Merger and the recent acquisition by
AmerUs of Delta. In the case of the income statement data, the table below

1996 for purposes of the unaudited pro forma combined income statement data for
the six months ended June 30, 1997 and the year ended December 31, 1996. In the
case of the balance sheet data, the table assumes that the Merger and
acquisition of Delta took place as of June 30, 1997 and December 31, 1996. The
unaudited pro forma combined income statement data do not give effect to AmerUs'
anticipated cost savings resulting from the acquisition of Delta or the Merger.

                           COMPARATIVE PER SHARE DATA
 
    The following table summarizes the per share information for AmerUs Class A
common stock and AmVestors common stock on a historical, pro forma combined, and
pro forma equivalent basis for the periods indicated below. The AmVestors pro
forma equivalents are calculated by multiplying the pro forma combined per share
amounts by the respective exchange ratio. The historical data for the six months
ended June 30, 1997 and the pro forma data for the six months ended June 30,
1997 are unaudited. The data presented as pro forma per share assumes that the
Merger is completed. This data is not necessarily indicative of the results of
the future operations of the consolidated organization or the actual results
that would have occurred if the Merger had been consummated prior to the periods
indicated.

(1) The AmVestors pro forma equivalent represents the AmerUs/AmVestors pro forma
   combined book value, dividends and earnings per common share multiplied by
   the respective exchange ratio of AmerUs Class A Common Stock for each share
   of AmVestors Common Stock so that the AmVestors pro forma equivalent amounts
   represent the respective values of one share of AmVestors Common Stock.
 
(2) In the event that the holders of AmVestors' stock options and stock warrants
    elect not to rollover and instead elect to receive cash, the impact on pro
    forma earnings per share would be less than $.02 per share. The total amount
    of funds required to cash out the stock options and the warrants would range
    from $18.9 million up to $22.6 million for the exchange ratio of .7407 and
    .6724, respectively, assuming an AmerUs Class A Common Stock price per share
    of $27 and $31.75, respectively.

                           FORWARD LOOKING STATEMENTS
 
    We have made forward-looking statements in this document (and, in the case
of AmVestors, in documents that are incorporated by reference) that are subject
to risk and uncertainties. Forward-looking statements include the information
concerning future results of operations, cost savings and synergies of AmerUs
and AmVestors after the Merger set forth under "QUESTIONS AND ANSWERS ABOUT THE
MERGER", "SUMMARY", "THE MERGER," "THE COMPANIES" "ADDITIONAL INFORMATION
REGARDING AMERUS--Management's Discussion and Analysis of Results of Operations
and Financial Condition of AmerUs," and "AMERUS LIFE HOLDINGS, INC., DELTA LIFE
CORPORATION AND AMVESTORS FINANCIAL CORPORATION UNAUDITED PRO FORMA CONDENSED
CONSOLIDATED FINANCIAL INFORMATION" and those preceded by, followed by or that
otherwise include the words "believes", "expects", "anticipates", "intends",
"estimates", or similar expressions. For those statements, we claim the
protection of the "safe harbor" section of the Private Securities Litigation
Reform Act of 1995. You should understand that the following important factors,
in addition to those discussed elsewhere in this document and in the documents
which have been incorporated by reference, could affect the future results of
AmerUs and AmVestors, and could cause those results to differ materially from
those expressed in our forward-looking statements:
 
    - heightened competition, including the entry of new competitors and the
      development of new products by competitors;
 
    - adverse state and federal legislation and regulation, including increases
      in minimum capital and reserves, and other financial viability
      requirements or application of the federal securities laws to the
      distribution of certain insurance and annuity products;
 
    - the failure to develop multiple distribution channels in order to obtain
      new customers or failure to retain existing customers;
 
    - the inability to carry out marketing and sales plans, including, among
      others, changes to certain products and acceptance of the revised products
      in the market;
 
    - loss of key executives;
 
    - changes in interest rates causing a reduction of investment income;
 
    - general economic and business conditions which are less favorable than
      expected;
 
    - unanticipated changes in industry trends;
 
    - inaccuracies in assumptions regarding future morbidity, persistency,
      mortality and interest rates used in calculating reserve amounts;
 
    - adverse changes in ratings assigned by rating agencies;
 
    - changes in tax laws which negatively affect demand for AmerUs' or
      AmVestors' products; and
 
    - with respect to cost savings that are expected to be realized from, and
      costs associated with, the following possibilities: (a) the expected cost
      savings to be realized through combining certain functions of AmerUs,
      AmVestors and Delta to eliminate redundancies and better serve AmerUs'
      customers cannot be fully realized because the changes are not made or
      unanticipated added costs are incurred; and (b) costs or difficulties
      related to the integration of the businesses of AmerUs, AmVestors and
      Delta are greater than expected.

                                  RISK FACTORS
 
    IN CONSIDERING WHETHER TO APPROVE AND ADOPT THE MERGER AGREEMENT, THE
STOCKHOLDERS OF AMVESTORS AND SHAREHOLDERS OF AMERUS SHOULD CONSIDER, IN
ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS JOINT PROXY
STATEMENT/PROSPECTUS, THE FOLLOWING MATTERS. CERTAIN CAPITALIZED TERMS USED IN
THIS SECTION ARE DEFINED IN OTHER SECTIONS OF THIS JOINT PROXY
STATEMENT/PROSPECTUS.
 
THE NUMBER OF SHARES OF CLASS A AMERUS COMMON STOCK THAT AMVESTORS STOCKHOLDERS
  WILL RECEIVE IN THE MERGER IS NOT FIXED
 
    To accomplish the Merger, AmerUs will issue to AmVestors stockholders a
certain number of shares of its Class A common stock for each share of AmVestors
common stock held by Amvestors stockholders immediately prior to completion of
the Merger, determined as follows:
 
    - if the average trading price for a share of AmerUs Class A common stock
      over the 20 trading day period ending on the tenth trading day prior to
      completion of the Merger is greater than or equal to $27.00 and less than
      or equal to $29.75, each AmVestors share will be converted into the
      fraction of a share of AmerUs Class A common stock equal to $20.00 divided
      by such average trading price;
 
    - if such average trading price is more than $29.75, each AmVestors share
      will be converted into 0.6724 shares of AmerUs Class A common stock;
 
    - if such average trading price is less than $27.00, each AmVestors share
      will be converted into 0.7407 shares of AmerUs Class A common stock;
 
    - if such average trading price is less than $27.00, the AmVestors Board may
      terminate the Merger Agreement unless AmerUs agrees to provide additional
      shares of AmerUs Class A common stock necessary to achieve a value of
      $20.00 per share of AmVestors common stock. The AmVestors Board is not
      required to exercise this termination right. Therefore, AmVestors
      stockholders could receive consideration in the Merger valuing their
      shares of AmVestors common stock at less than $20.00 per share. If the
      stock issuance is approved, the AmerUs Board would have the authority to
      increase the number of shares to be issued in order to achieve the value
      of $20.00 per share.
 
    In the trading range between $29.75 and $27.00 a higher average trading
price of AmerUs Class A common stock during the 20 trading day period will
result in fewer AmerUs shares being issued to AmVestors stockholders. If the
special shareholder meetings are held before the 20 trading day period has
occurred, AmVestors stockholders will not know precisely how many shares of
AmerUs Class A common stock they will receive in the Merger and AmerUs
shareholders will not know precisely how many shares will be issued in the stock
issuance.
 
UNCERTAINTIES IN INTEGRATING OPERATIONS AND ACHIEVING COST SAVINGS
 
    As a result of the Merger and the acquisition of Delta, AmerUs will
substantially increase in size. The success of the Merger and the acquisition of
Delta depends on the ability of AmerUs to combine operations, integrate
departments, systems and procedures and obtain cost savings following the
Merger. While management of AmerUs and AmVestors intend to work diligently to
integrate and rationalize the operations following the Merger and the
acquisition of Delta, there can be no assurance as to the timing or extent of
cost savings and efficiencies that will be achieved. It is not certain that the
anticipated benefits of the Merger and the acquisition of Delta will be
realized.
 
NECESSITY OF RECEIVING GOVERNMENTAL APPROVALS
 
    In order to complete the Merger, the insurance regulatory agency in Kansas
must approve the Merger, the insurance regulatory agency in Iowa must approve
the stock issuance and the insurance regulatory agencies in Florida and Kansas
must approve the redomestication of Financial Benefit Life Insurance Company
("FBL") from Florida to Kansas. In addition, the waiting period required under
the Hart-Scott-Rodino Act must have expired. Various other approvals or
conditions also must be satisfied.

No assurance can be given that the required approvals will be obtained and all
the conditions necessary to complete the Merger will be satisfied. See "THE
MERGER--Regulatory Approvals."
 
HOLDING COMPANY STRUCTURE; LIMITATIONS ON DIVIDENDS
 
    AmerUs is an insurance holding company whose assets consist primarily of all
of the outstanding stock of AmerUs Life and Delta, and if the Merger is
completed, of AmVestors. AmerUs' ongoing ability to pay dividends to its
shareholders and meet its other obligations depends primarily upon receipt of
sufficient funds from its subsidiaries in the form of dividends or interest
payments.
 
    The payment of dividends to AmerUs by its insurance subsidiaries is
regulated under state insurance laws. Under Iowa law, AmerUs Life may pay
dividends only from the earned surplus arising from its business. It must
receive the prior approval of the Iowa Commissioner to pay a dividend if such
dividend would exceed certain statutory limitations. As a result of an
extraordinary dividend paid in December 1996, AmerUs Life is not able to pay any
dividends until December 1997 without the prior approval of the Iowa
Commissioner. As of September 30, 1997, AmerUs Life had requested and received
approval for the payment of $10 million in dividends. The payment of dividends
by Delta Life to Delta is regulated under Tennessee law, which has statutory
limitations similar to Iowa's. Based on these limitations and 1996 results,
Delta Life could pay $8.7 million in dividends in 1997. The payment of dividends
by AmVestors' insurance subsidiaries to AmVestors is regulated under Kansas and
Florida law. Kansas has statutory limitations similar to Iowa. Under Florida
law, the aggregate dividends that FBL may pay without prior regulatory approval
is limited to $3.8 million (and similar restrictions would apply to FBL under
Kansas law following the planned redomestication). Based upon these limitations
and 1996 results, AmVestors' insurance subsidiaries could pay $13.9 million in
dividends in 1997 without obtaining prior regulatory approval. AmVestors'
insurance subsidiaries paid $2.2 million in 1997 dividends through September 30,
1997.
 
    If AmerUs Life, Delta or AmVestors cannot pay dividends or interest to
AmerUs in the future, it could have a material adverse effect on AmerUs and the
market value of the AmerUs Class A common stock. See "ADDITIONAL INFORMATION
REGARDING AMERUS--Business--Supervision and Regulation" and "DESCRIPTION OF
AMERUS CAPITAL STOCK."
 
    Under the terms of its existing credit agreement with its banks, AmerUs is
prohibited from paying cash dividends on AmerUs' capital stock in excess of an
amount equal to 3% of AmerUs' consolidated net worth as of the last day of the
preceding fiscal year. AmerUs has also pledged to its lenders approximately
49.9% of the outstanding common stock of AmerUs Life owned by AmerUs, 100% of
the outstanding common stock of Delta and a $50 million 9% note payable to
AmerUs by AmerUs Life. See "ADDITIONAL INFORMATION REGARDING
AMERUS--Business--Certain Transactions and Relationships."
 
    In connection with the 8.85% Capital Securities, Series A, issued in
February 1997 by AmerUs Capital I, AmerUs' subsidiary trust, AmerUs has agreed
not to declare or pay any dividends on AmerUs' capital stock, including the
AmerUs Class A common stock, during any period of time in which dividends on the
Capital Securities are suspended, except for stock dividends. Other dividends in
respect of AmerUs' capital stock cannot be paid until all accrued dividends on
the Capital Securities have been paid.
 
CONTROL BY AMHC; ANTI-TAKEOVER EFFECTS OF IOWA LAW AND AMERUS CHARTER AND BYLAWS
 
    Under Iowa law and the AmerUs Charter, AMHC, as a mutual insurance holding
company, is required to own, directly or indirectly, shares of capital stock of
AmerUs Life which carry the right to cast a majority of the votes entitled to be
cast by all of the outstanding shares of AmerUs Life's capital stock.
Consequently, AMHC may, without the approval of the other shareholders of
AmerUs, elect all of the directors of AmerUs and approve matters submitted for
shareholder approval. In addition, unless AMHC is demutualized, an action beyond
AmerUs' control, AmerUs cannot be the subject of a successful takeover bid.
Certain provisions in AmerUs' Charter and Bylaws may delay, defer or prevent a
takeover
 
                                       16
<PAGE>
attempt that a shareholder might consider in his or her best interests. These
provisions include supermajority voting rights for AmerUs Class B common stock,
the ability of the board of directors to issue so-called "blank check" preferred
stock and a classified board of directors. Such provisions may adversely affect
the prevailing market price of the AmerUs Class A common stock. See "DESCRIPTION
OF AMERUS CAPITAL STOCK," "COMPARISON OF SHAREHOLDER RIGHTS" and "ADDITIONAL
INFORMATION REGARDING AMERUS--Business--Supervision and Regulation."
 
RELATIONSHIP WITH AMHC; POTENTIAL CONFLICTS OF INTEREST
 
    AMHC is a mutual holding company which is operated for the benefit of its
members. The members of AMHC are policyowners of AmerUs Life. AMHC (or certain
of its wholly-owned subsidiaries) have entered into agreements with AmerUs
and/or AmerUs Life in which AmerUs and/or AmerUs Life will provide to such
subsidiaries certain management, data processing, legal and other services, or
such subsidiaries will provide services to AmerUs and/or AmerUs Life. AmerUs
management believes the terms of such agreements are fair and reasonable.
However, none of these contracts were the result of arms' length negotiations
between independent parties. These agreements may be modified in the future.
Additional agreements or transactions may be entered into between AMHC or
subsidiaries of AMHC and AmerUs and its subsidiaries. See "ADDITIONAL
INFORMATION REGARDING AMERUS-- Business--Certain Transactions and
Relationships."
 
    As a result of these arrangements, there may be a number of potential
conflicts of interest between AmerUs and AMHC. In an effort to address such
potential conflicts, and as required by regulations of the Iowa Commissioner,
three of AmerUs' outside directors are not directors of AMHC or any of AMHC's
subsidiaries. These outside directors comprise AmerUs' Intercompany Transactions
Committee which reviews intercompany transactions involving potential
conflicting interests. However, there can be no assurance that decisions made by
AMHC will not adversely affect AmerUs. See "ADDITIONAL INFORMATION REGARDING
AMERUS--Business--Certain Transactions and Relationships" and "MANAGEMENT BEFORE
AND AFTER THE MERGER."
 
    The National Association of Insurance Commissioners has formed a working
group to review mutual holding company legislation and regulations. The working
group's review could address, among other things, potential restrictions on
stock ownership by directors and officers, the utilization of non-voting or low
voting stock, standards for affiliate transactions, and regulation of potential
conflicts of interests. It is unclear what effect, if any, this review would
have but it is possible that insurance regulators, including Iowa, could propose
additional laws or regulations which would affect current laws such as exist in
Iowa and, as a result, might inhibit transactions between affiliates, future
stock issuances, the ability of officers and directors to secure significant
ownership positions in AmerUs or otherwise restrict the ability of AmerUs to
take advantage of new business opportunities.
 
RESTRICTIONS ON RATIO OF AMERUS STOCK CLASSES
 
    The AmerUs Charter provides that the number of outstanding shares of AmerUs
Class A common stock not beneficially owned by AMHC shall not exceed the number
of outstanding shares of AmerUs Class B common stock plus the shares of AmerUs
Class A common stock beneficially owned by AMHC by a ratio of more than three to
one. As a result, AmerUs' ability to issue additional shares of AmerUs Class A
common stock for any reason, including raising additional equity capital, for
stock options or in connection with acquisitions may be restricted if such
condition should occur. Immediately following completion of the Merger, it is
anticipated that such ratio will be between approximately 1.08 to one and 1.15
to one (excluding the effect of shares of AmVestors Common Stock or AmerUs
Common Stock acquired by AmerUs Group after the date hereof).
 
COMPETITIVE ENVIRONMENT
 
    AmerUs competes with a large number of other insurers and non-insurance
financial service companies, such as banks, broker-dealers and mutual funds.
Many competitors have greater financial resources and offer alternative
products. Other insurers have higher claims-paying ability and financial
 
                                       17
<PAGE>
strength ratings than AmerUs. Competition exists for individual consumers and
agents and other distributors of life insurance and annuity products. Banks,
with their pre-existing customer bases for financial services products, may pose
increasing competition in the future to life insurers.
 
    Congress is considering changing the laws which regulate banks, insurance
companies and other financial institutions. These changes may permit banks to
own insurance companies and vice versa. None of these proposals has yet been
enacted. It is not possible to predict whether any of these proposals will be
enacted or, if enacted, their potential effect on AmerUs.
 
    AmerUs must attract and retain productive agents to sell its life insurance
and annuity products. Strong competition exists among insurance companies for
agents with demonstrated ability. Competition among insurance companies for such
agents is based on the services provided to, and relationships developed with,
these agents in addition to compensation and product structure.
 
IMPORTANCE OF RATINGS
 
    Ratings with respect to claims-paying ability and financial strength have
become an increasingly important factor in establishing the competitive position
of insurance companies. Each of the rating agencies reviews its ratings
periodically and there can be no assurance that current ratings will be
maintained in the future. Claims-paying and financial strength ratings are based
upon factors relevant to policyowners and are not directed toward protection of
shareholders.
 
    The following are the ratings as of the date of the Joint Proxy
Statement/Prospectus for the various insurance companies of AmerUs and
AmVestors:

* Subsidiary of AmVestors
 
    Following announcement of the Merger, certain of the rating agencies issued
statements regarding their ratings. Duff & Phelps reaffirmed its AA-(very high)
claims-paying ability rating of AmerUs Life. Duff & Phelps said it views the
Merger as having long term positive implications. Standard & Poor's has placed
its claims-paying rating of AmerUs Life on Credit Watch with negative
implications. Standard & Poor's stated that its action results from several
operational uncertainties. A. M. Best reaffirmed the A (excellent) rating of
AmerUs Life stating that expanded economies of scale for new business systems
and product support systems should enable it to improve earnings. Following
announcement of the acquisition of Delta, Moody's indicated that AmerUs Life,
rated A2 (good) for financial strength, was under review for possible downgrade.
Moody's has not issued any further statement with respect to AmerUs Life's
financial strength rating since announcement of the Merger.
 
    Also following the announcement of the Merger, Duff & Phelps placed the A
(high) claims-paying ability rating of American Investors Life on "rating watch
up," reflecting potential benefits of the Merger. A. M. Best affirmed its
ratings for American Investors Life and Financial Benefit Life. Moody's placed
the Ba3 (questionable) subordinated debt rating of AmVestors on review for
possible upgrade.
 
                                       18
<PAGE>
    Also following the announcement of the Merger, A. M. Best reaffirmed the A-
(excellent) rating for American Investors Life and the B+ (very good) rating for
Financial Benefit Life.
 
    Future downgrades in the ratings of AmerUs' life subsidiaries could
significantly affect sales of life insurance and annuity products and could have
a material adverse effect on the results of operations of AmerUs after the
Merger. See "ADDITIONAL INFORMATION REGARDING AMERUS--Business" and
"--Management's Discussion and Analysis of Results of Operations and Financial
Condition of AmerUs."
 
INTEREST RATE FLUCTUATIONS; RISK OF IMPACT OF FORCED LIQUIDATION OF INVESTMENT
  PORTFOLIO
 
    Severe interest rate fluctuations could adversely affect the ability of
AmerUs' life insurance subsidiaries to pay policyowner benefits with operating
and investment cash flows, cash on hand and other cash sources. See "ADDITIONAL
INFORMATION REGARDING AMERUS--Management's Discussion and Analysis of Results of
Operations and Financial Condition of AmerUs."
 
    Interest rate fluctuations may also have an impact on policyowner behavior.
If AmerUs does not maintain competitive interest rates with those credited in
the marketplace, increased policy terminations may be experienced. While
policyholders may pay surrender charges to terminate policies, such terminations
would reduce AmerUs' future income.
 
    AmerUs' actual cash flows from investments may differ from those anticipated
at the time of investment. Some of AmerUs' corporate bonds have provisions which
could cause AmerUs to reinvest these proceeds at lower interest rates if such
bonds were prepaid prior to their stated maturities. AmerUs' collateralized
mortgage obligations and other asset-backed securities are purchased based on
assumptions regarding rates of prepayments. If actual prepayments are earlier or
later than anticipated at the time of purchase, AmerUs may not receive cash
flows when expected or needed. These prepayment rates are influenced by interest
rates available for new mortgages as well as general economic conditions.
 
    Most of AmerUs' insurance and annuity products provide for guaranteed
minimum yields. Accordingly, a significant drop in market rates of interest
could have a material impact on AmerUs' future results of operations.
 
FUTURE POLICY BENEFITS EXPOSURE
 
    The liability established by AmerUs for future life insurance and annuity
policy benefits is based upon assumptions concerning a number of factors. Such
factors include interest rates, mortality, duration of the policies and
expenses. Actual experience will likely differ from assumed experience. If
AmerUs' provision for future policy benefits proves inadequate, future earnings
will be adversely affected.
 
REGULATORY AND RELATED RISKS
 
    AmerUs' life insurance subsidiaries are subject to regulation by state
regulators under the insurance laws of states in which they conduct business.
AmerUs, AmerUs Group and AMHC are regulated by the Iowa Insurance Division. In
addition, American is regulated by the Kansas Department of Insurance and FBL is
regulated by the Florida Department of Insurance (and would be regulated by the
Kansas Department of Insurance following the planned redomestication). Delta is
regulated by the Tennessee Department of Insurance. The purpose of such
regulation is primarily to provide safeguards for policyowners rather than to
protect the interests of shareholders. The insurance laws of the various states
establish regulatory agencies with broad administrative powers including the
authority to grant or revoke operating licenses and to regulate sales practices,
investments, deposits of securities, the form and content of financial
statements and insurance policies, accounting practices and the maintenance of
specified reserves and capital. In addition, the Iowa Commissioner has adopted
rules regulating the issuance of stock by AmerUs in equity offerings.
Additionally, upon the occurrence of a change of control, certain states in
which AmVestors' insurance subsidiaries do business require that insurance
 
                                       19
<PAGE>
companies submit new applications to qualify to do business in such states.
There can be no assurances that the new applications of AmVestors' insurance
subsidiaries will be approved to permit them to continue to operate in these
states. The inability to operate in these states could have a material adverse
impact on the sales of such subsidiaries. See "ADDITIONAL INFORMATION REGARDING
AMERUS-- Business--Supervision and Regulation."
 
    Insurance regulators have in recent years investigated allegations of
improper sales practices by insurance agents, including churning and misleading
sales presentations. The National Association of Insurance Commissioners has
adopted a model law and regulation which would standardize the form and content
of any illustrations provided to prospective purchasers of individual life
insurance products. The model law has been enacted in a number of states. AmerUs
expects that similar laws will eventually be enacted in additional states in
which AmerUs sells individual life insurance products. There can be no assurance
as to whether any such changes will have a material adverse impact on sales of
such products by the industry as a whole or by AmerUs.
 
    Certain of AmerUs' insurance and annuity products are innovative and
relatively new. The regulatory framework at the state and federal level
applicable to such products is evolving. The changing regulatory framework could
affect the design of such products and AmerUs' ability to sell certain products.
For example, in August 1996, the SEC requested information and comments about
the structure of equity index insurance products, the manner in which they are
marketed and the federal securities law issues raised by equity index insurance
products. It is possible that the SEC may propose new regulations or policies
with respect to equity index insurance products which may affect the marketing
of such products or impose requirements that some or all such products be
registered with the SEC. See "ADDITIONAL INFORMATION REGARDING
AMERUS--Business--Supervision and Regulation."
 
RISKS OF CLASS ACTION LITIGATION
 
    In recent years, a number of life insurance companies, including AmerUs
Life, have been named defendants in class action lawsuits arising out of their
business practices. Although AmerUs has denied all allegations against it and
has vigorously defended against the class action lawsuits which have been
brought against its life insurance subsidiaries, there can be no assurance that
any such litigation will not have a material adverse effect on the life
insurance industry generally or on AmerUs. See "ADDITIONAL INFORMATION REGARDING
AMERUS--Management's Discussion and Analysis of Results of Operations and
Financial Condition of AmerUs" and "--Business--Legal Proceedings."
 
ADVERSE TAX LEGISLATION AND ADMINISTRATIVE PRONOUNCEMENTS
 
    Congress has from time to time considered legislation that would reduce or
eliminate the benefits to policyowners of the deferral of taxation on the
increase of value within certain annuities and life insurance products. Other
proposals affect the taxation of annuities and life insurance products and
insurance companies. A new federal tax law reduces the rate of taxation on
certain long-term capital gains for individuals. This legislation, along with
other possible proposals or administrative pronouncements, including those
relating to the dividends received deduction, the applicability of the equity
add-on tax, and ordinary versus capital gain treatment for corporations, could
adversely affect the taxation of AmerUs or the sale of annuities and life
insurance products. Similarly, there can be no certainty as to what, if any,
future laws or administrative pronouncements on these issues might be enacted or
promulgated or whether any such laws or pronouncements would have any adverse
effects on AmerUs.
 
RISKS RELATING TO THE CLOSED BLOCK
 
    In connection with the reorganization undertaken by AmerUs in June 1996 (the
"AMERUS REORGANIZATION"), AmerUs Life was required to allocate specific assets
for the benefit of insurance policies and annuities existing at the time of the
AmerUs Reorganization that pay dividends or provide interest credits. This is
known as a "Closed Block." The Closed Block is designed to give reasonable
assurance to policyowners that, after the AmerUs Reorganization, assets will be
available to maintain policy dividends and interest credits in effect prior to
the AmerUs Reorganization if the same experience and performance
 
                                       20
<PAGE>
continues. The investment performance of the assets in the Closed Block and the
performance of the policies covered by the Closed Block will affect future
dividends and interest credits. Any excess of cumulative favorable experience
for Closed Block policies over unfavorable experience will be available for
distribution over time to Closed Block policyowners and will not be available to
AmerUs Life or AmerUs. Unless the Iowa Commissioner consents to an earlier
termination, the Closed Block will continue to be in effect until the date on
which none of the policies in the Closed Block remains in force.
 
    AmerUs will continue to pay guaranteed benefits under all policies,
including the policies included in the Closed Block in accordance with their
terms. If the assets allocated to the Closed Block, the investment cash flows
from those assets and the revenues from the policies included in the Closed
Block including investment income thereon prove to be insufficient to pay the
benefits guaranteed under the policies included in the Closed Block, AmerUs will
be required to make such payments from its general funds. AmerUs bears the costs
of operating and managing the Closed Block and, accordingly, such costs were not
funded as part of the assets allocated to the Closed Block. Any increase in such
costs in the future would be borne by AmerUs. See "ADDITIONAL INFORMATION
REGARDING AMERUS-- Business--The AmerUs Reorganization--Establishment and
Operation of the Closed Block."
 
RISKS RELATING TO YEAR 2000 COMPLIANCE
 
    Many existing computer software programs and operating systems were designed
such that the year 1999 is the maximum date that many computer systems will be
able to process. AmerUs has formed a working group to address potential problems
posed by this limitation in systems software to assure that AmerUs is prepared
for the year 2000. If modifications and conversion to deal with year 2000 issues
are not completed on a timely basis or are not fully effective, such issues may
have a material adverse effect on the results of operations of AmerUs. See
"ADDITIONAL INFORMATION REGARDING AMERUS--Management's Discussion and Analysis
of Results of Operations and Financial Condition of AmerUs--Year 2000
Compliance."
 
AMERUS CLASS A COMMON STOCK ELIGIBLE FOR FUTURE SALE
 
    Sales of substantial amounts of AmerUs Class A common stock (including
shares of AmerUs Class B common stock converted into AmerUs Class A common
stock), or the perception that such sales could occur, could have an adverse
effect on the price of the AmerUs Class A common stock. As of the date of this
Joint Proxy Statement/Prospectus, AMHC beneficially owns 11,706,511 shares of
Amerus Class A common stock. All of the shares of AmerUs Class A common stock
which are currently beneficially owned by AMHC are eligible for sale under SEC
rules, subject to certain volume and timing limitations. AmerUs Group has
advised AmerUs that it intends to acquire additional shares of either AmerUs
Common Stock or AmVestors Common Stock which would be converted into AmerUs
Class A Common Stock. However, there can be no assurance that such purchases
would be made, or if made, that such shares would not be resold.
 
LIMITED TRADING HISTORY FOR AMERUS CLASS A COMMON STOCK; POSSIBLE VOLATILITY OF
  AMERUS CLASS A COMMON STOCK PRICE
 
    From January 28, 1997 (the date on which the AmerUs Class A common stock
began trading on Nasdaq) through November 11, 1997, the per share bid price of
the AmerUs Class A common stock has fluctuated from a low of $19 1/8 to a high
of $35-1/2. In the future, the market price for the AmerUs Class A common stock
may be significantly affected by AmerUs' operating results, the ability of
AmerUs to successfully integrate the Merger and the acquisition of Delta and
fluctuations in the stock market generally, as well as general economic
conditions.

and into AmVestors pursuant to the Amended and Restated Agreement and Plan of
Merger, dated as of September 19, 1997, as amended and restated on October 8,
1997 (the "MERGER AGREEMENT"). As a result of the Merger, AmVestors would become
a wholly owned subsidiary of AmerUs and all outstanding shares of common stock,
no par value, of AmVestors ("AMVESTORS COMMON STOCK") would be converted into

                                 THE COMPANIES
 
AMERUS LIFE HOLDINGS, INC.
 
    AmerUs is an insurance holding company engaged through its subsidiaries in
the business of marketing, underwriting and distributing a broad range of
individual life insurance and annuity products to individuals and businesses in
49 states and the District of Columbia. AmerUs' primary product offerings
consist of whole life, universal life and term life insurance policies and fixed
annuities. In connection with a joint venture (the "AMERITAS JOINT VENTURE")
with Ameritas Life Insurance Corp. ("AMERITAS"), AmerUs' subsidiary, AmerUs Life
Insurance Company ("AMERUS LIFE") markets fixed annuities issued by Ameritas
Variable Life Insurance Company ("AVLIC") and sells AVLIC's variable life
insurance and variable annuity products. As of June 30, 1997, AmerUs had
approximately 424,000 life insurance policies and annuity contracts outstanding
and individual life insurance in force, net of reinsurance, of approximately
$25.9 billion. As of June 30, 1997, AmerUs had total assets of $4.5 billion and
total shareholders' equity of $535 million.
 
    AmerUs' principal subsidiaries are AmerUs Life and Delta Life Corporation
("DELTA"). AmerUs Life was originally incorporated in 1896 as a mutual insurance
company under the name Central Life Assurance Society of the United States
("CENTRAL LIFE"). On June 30, 1996, AmerUs Life was converted into a stock life
insurance company as part of the AmerUs Reorganization. As part of the AmerUs
Reorganization, all of the shares of capital stock of AmerUs Life were issued to
American Mutual Holding Company, an Iowa mutual insurance holding company
("AMHC"), which subsequently contributed such shares to its wholly-owned
subsidiary, AmerUs Group Co. ("AMERUS GROUP"), which in turn contributed such
shares to AmerUs. See "ADDITIONAL INFORMATION REGARDING AMERUS--Business--The
AmerUs Reorganization."
 
    On October 23, 1997, AmerUs acquired all of the outstanding capital stock of
Delta for $162.9 million in cash. As of June 30, 1997, Delta had approximately
52,000 annuity contracts outstanding, had assets of $2.0 billion, had total
stockholders' equity of $107.4 million, and had reserves of approximately
 
                                       22
<PAGE>
$1.8 billion. See "ADDITIONAL INFORMATION REGARDING AMERUS--Business--Recent
Developments--Acquisition of Delta Life Corporation."

                           THE AMERUS SPECIAL MEETING
 
GENERAL
 
    This Joint Proxy Statement/Prospectus is provided to the shareholders of
AmerUs in connection with the solicitation of proxies by the AmerUs Board for
use at the AmerUs Special Meeting to be held on December 18, 1997 at 10:00 a.m.,
local time, at the offices of AmerUs Life Insurance Company at 611 Fifth Avenue,
Des Moines, Iowa and at any adjournments or postponements thereof. A form of
proxy is being provided to the shareholders of AmerUs with this Joint Proxy
Statement/Prospectus in connection with the solicitation of proxies by the
AmerUs Board for use at the AmerUs Special Meeting.
 
MATTERS TO BE CONSIDERED
 
    At the AmerUs Special Meeting, shareholders will be asked to (i) approve the
Stock Issuance pursuant to the Merger, and (ii) vote upon such other business as
may properly come before the AmerUs Special Meeting or any adjournments or
postponements thereof. The AmerUs Board knows of no business that will be
presented for consideration at the AmerUs Special Meeting other than the matters
described in this Joint Proxy Statement/Prospectus. The aggregate number of
shares of AmerUs Class A Common Stock issued in connection with the Stock
Issuance immediately following the Merger is expected to be between
approximately 11.6 million and 12.8 million shares (based upon an Average AmerUs
Share Price of $27.00 and $29.75, respectively, and in each case assuming that
treasury shares are eliminated and all options and warrants are rolled over into
options to acquire shares of AmerUs Class A Common Stock). Unless AmerUs agrees
to pay the Adjusted Merger Consideration (as defined below), the aggregate
number of shares of AmerUs Class A Common Stock issuable in connection with the
Merger should not be more than 14.7 million shares (which would occur if the
Average AmerUs Share Price is $27.00 or less, and assuming conversion of the
AmVestors Convertible Debentures and exercise of all outstanding options and
warrants to purchase AmVestors Common Stock). See "THE MERGER--Merger
Consideration". If the Average AmerUs Trading Price is less than $27.00, the
AmVestors Board may terminate the Merger Agreement unless AmerUs agrees to
provide additional shares of AmerUs Class A Common Stock necessary to achieve a
value of $20 per share of AmVestors Common Stock. If the Stock Issuance is
approved, the AmerUs Board would have the authority to increase the shares being
issued in order to achieve the value of $20 per share. AmerUs shareholders
should note that the exact number of shares to be issued in the Merger is not
likely to be known at the time of the AmerUs Special Meeting. The AmVestors
Board is not required to exercise this termination right. Therefore, AmVestors
stockholders could receive consideration in the Merger valuing their shares of
AmVestors Common Stock at less than $20 per share.
 
    The vote on the Stock Issuance is being taken because AmerUs, as a company
whose shares are listed and traded on Nasdaq, must comply with a Nasdaq rule
requiring shareholder approval if AmerUs issues common stock in connection with
the acquisition of the stock or assets of another company that has or will have
voting power equal to or in excess of 20% of the voting power outstanding before
such issuance or the number of shares of common stock to be issued is or will be
equal to or in excess of 20% of the number of shares of common stock outstanding
before such issuance. The Stock Issuance would result in the issuance of AmerUs
Class A Common Stock in excess of 20% of the number of shares of AmerUs Common
Stock outstanding before the Stock Issuance. The AmerUs Board has determined
that the Merger and the Stock Issuance are advisable and in the best interests
of AmerUs and its shareholders and has approved the Merger and the Stock
Issuance by unanimous vote of those directors voting. ACCORDINGLY, THE AMERUS
BOARD RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THE STOCK ISSUANCE. See
"THE MERGER--Background of the Merger" and "--AmerUs' Reasons for the Merger and
the Stock Issuance; Recommendation of the AmerUs Board."
 
    SHAREHOLDERS ARE REQUESTED TO PROMPTLY COMPLETE, DATE, SIGN AND RETURN THE
ACCOMPANYING PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

RECORD DATE; QUORUM
 
    Only shareholders of record of AmerUs Common Stock at the close of business
on November 5, 1997 (the "AMERUS MEETING RECORD DATE") will be entitled to
receive notice of, and to vote at, the AmerUs Special Meeting and any
adjournments or postponements thereof. As of the AmerUs Meeting Record Date,
there were issued and outstanding 18,155,989 shares of AmerUs Class A Common
Stock and 5,000,000 shares of Class B Common Stock. A majority of the
outstanding shares of AmerUs Common Stock entitled to vote must be represented
in person or by proxy at the AmerUs Special Meeting in order for a quorum to be
present. If such a quorum is not present, a majority of shares so represented
may adjourn or postpone the AmerUs Special Meeting to a future date.
 
VOTE REQUIRED
 
    The approval of the Stock Issuance requires the affirmative vote of the
majority of the votes cast by the holders of outstanding shares of AmerUs Common
Stock present at a meeting duly held at which a quorum is present. Shares which
are present but not voted, either by abstention or non-vote (including broker
non-vote), will be counted for establishing a quorum but will not be counted to
determine whether the Stock Issuance is approved. Each share of AmerUs Common
Stock will be entitled to one vote.
 
    As of the AmerUs Meeting Record Date, AmerUs' directors and executive
officers and their affiliates may be deemed to be beneficial owners of
16,783,210 shares of AmerUs Common Stock representing approximately 72% of the
outstanding AmerUs Common Stock. As of the AmerUs Meeting Record Date, AMHC
beneficially owned 16,706,511 of such shares of AmerUs Common Stock (the "AMHC
SHARES"). On September 19, 1997, the Board of Directors of AMHC approved
resolutions authorizing appropriate officers and its affiliates to cause the
AMHC Shares to be voted in favor of the Stock Issuance. Since the AMHC Shares
constitute a majority of the outstanding shares of AmerUs Common Stock as of the
record date for the AmerUs Special Meeting, the vote of shares beneficially
owned by AMHC would be sufficient to approve the Stock Issuance, regardless of
whether any other AmerUs shareholder votes in favor of the Stock Issuance. See
"SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT--AmerUs Common
Stock."
 
PROXIES
 
    Shares represented by properly executed proxies received in time for the
AmerUs Special Meeting will be voted at the AmerUs Special Meeting, including at
any adjournment or postponement thereof, in the manner specified by the holder
thereof. Proxies which are properly executed but which do not contain voting
instructions will be voted in favor of approval of the Stock Issuance. If a
quorum is not present at the AmerUs Special Meeting, the persons appointed as
proxies will not have the discretion to vote or act to adjourn or postpone the
AmerUs Special Meeting according to their judgment.
 
    The grant of a proxy on the enclosed AmerUs form does not preclude a
shareholder from voting in person. A shareholder may revoke a proxy at any time
prior to its exercise by submitting a new proxy at a later date, by filing with
the Secretary of AmerUs a duly executed revocation of proxy bearing a later date
or by voting in person at the meeting, including at any adjournment or
postponement thereof. Attendance at the AmerUs Special Meeting will not of
itself constitute revocation of a proxy.
 
SOLICITATION OF PROXIES
 
    AmerUs will bear the cost of solicitation of proxies from its shareholders,
except that AmerUs and AmVestors will share equally the cost of printing this
Joint Proxy Statement/Prospectus. In addition to solicitation by mail, the
directors, officers and employees of AmerUs and its subsidiaries may solicit
proxies, without receiving additional compensation therefor, by telephone,
telefax or telegram or in person. Arrangements will also be made with brokerage
houses and other custodians, nominees and fiduciaries for the forwarding of
solicitation materials to the beneficial owners of stock held of record by such
persons, and AmerUs will reimburse such brokerage houses, custodians, nominees
and fiduciaries for the reasonable out-of-pocket expenses in connection
therewith.

                         THE AMVESTORS SPECIAL MEETING
 
GENERAL
 
    This Joint Proxy Statement/Prospectus is being furnished to the stockholders
of AmVestors in connection with the solicitation of proxies by the AmVestors
Board for use at the AmVestors Special Meeting to be held on December 18, 1997
at 10:00 a.m., local time, at the Kansas City Airport Marriott, 775 Brasilia
Street, Kansas City, Missouri, and at any adjournments or postponements thereof.
Each copy of this Joint Proxy Statement/Prospectus mailed to stockholders is
accompanied by a proxy card furnished in connection with the solicitation of
proxies by the AmVestors Board for use at the AmVestors Special Meeting.
 
MATTERS TO BE CONSIDERED
 
    At the AmVestors Special Meeting, stockholders will be asked to (i) approve
the Merger Agreement and the transactions contemplated thereby, and (ii) vote
upon such other business as may properly come before the AmVestors Special
Meeting or any adjournments or postponements thereof (including, without
limitation, adjournment of the AmVestors Special Meeting in order to allow for
additional solicitation of stockholder votes in order to obtain a quorum or in
order to obtain more votes in favor of the Merger Agreement). The AmVestors
Board knows of no business that will be presented for consideration at the
AmVestors Special Meeting other than the matters described in this Joint Proxy
Statement/ Prospectus.
 
    The AmVestors Board has determined that the Merger and the Merger Agreement
are advisable and in the best interests of AmVestors and its stockholders and
has approved the Merger and the Merger Agreement by unanimous vote of those
directors voting. ACCORDINGLY, THE AMVESTORS BOARD RECOMMENDS THAT AMVESTORS
STOCKHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. See "THE
MERGER--Background of the Merger" and "--AmVestors' Reasons for the Merger;
Recommendation of the AmVestors Board."
 
    STOCKHOLDERS ARE REQUESTED TO PROMPTLY COMPLETE, DATE, SIGN AND RETURN THE
ACCOMPANYING PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE. FAILURE TO RETURN
A PROPERLY EXECUTED PROXY CARD OR TO VOTE AT THE SPECIAL MEETING WILL HAVE THE
SAME EFFECT AS A VOTE AGAINST THE MERGER AGREEMENT.
 
RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM
 
    Only the holders of record of AmVestors Common Stock as of the close of
business on November 11, 1997 (the "AMVESTORS MEETING RECORD DATE") will be
entitled to notice of and to vote at the AmVestors Special Meeting. At the close
of business on November 10, 1997, there were 12,215,888 shares of AmVestors
Common Stock outstanding and entitled to vote, held by approximately 3,800
stockholders of record. Directors and executive officers of AmVestors and its
affiliates (as a group) were entitled to vote 767,991 shares of AmVestors Common
Stock, or approximately 4.5% of the outstanding votes entitled to be cast at the
AmVestors Special Meeting; all such persons have indicated to AmVestors their
intention to vote their shares of AmVestors Common Stock FOR the approval and
adoption of the Merger Agreement and the transactions contemplated thereby.
Holders of record of AmVestors Common Stock as of the close of business on the
AmVestors Meeting Record Date are entitled to one vote per share on any matter
voted on at the AmVestors Special Meeting.
 
    The presence, either in person or by proxy, of the holders of a majority of
the outstanding shares of AmVestors Common Stock as of the AmVestors Meeting
Record Date is necessary to constitute a quorum at the AmVestors Special
Meeting. Broker non-votes and abstentions count for the purpose of determining a
quorum at the AmVestors Special Meeting. If a quorum is not obtained, or if
fewer shares are likely to be voted in favor of approval and adoption of the
Merger Agreement than the number required for approval, it is expected that the
AmVestors Special Meeting will be adjourned for the purpose of allowing
additional time for soliciting and obtaining additional proxies or votes or for
any
 
                                       26
<PAGE>
other purpose, including obtaining necessary regulatory approvals, and, at any
subsequent reconvening of the AmVestors Special Meeting, all proxies will be
voted in the same manner as such proxies would have been voted at the original
convening of the meeting (except for any proxy which has been effectively
revoked or withdrawn), notwithstanding that such proxy may have been effectively
voted on the same or any other matter at a previous meeting.
 
    STOCKHOLDERS SHOULD NOT FORWARD ANY COMMON STOCK CERTIFICATES WITH THEIR
PROXY CARDS. IN THE EVENT THE MERGER IS CONSUMMATED, STOCK CERTIFICATES SHOULD
BE DELIVERED IN ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF
TRANSMITTAL, WHICH WILL BE SENT TO STOCKHOLDERS BY CHASEMELLON SHAREHOLDER
SERVICES LLC, IN ITS CAPACITY AS THE EXCHANGE AGENT, PROMPTLY AFTER THE
EFFECTIVE TIME.
 
VOTE REQUIRED
 
    The affirmative vote of the holders of at least a majority of the
outstanding shares of AmVestors Common Stock entitled to vote on the matters to
be acted upon is required to approve and adopt the Merger Agreement and the
transactions contemplated thereby. The failure to submit a proxy card (or vote
in person at the AmVestors Special Meeting) or the abstention from voting by a
stockholder (including broker non-votes) shall have the same effect as a vote
against the Merger Agreement. Brokers who hold shares of AmVestors Common Stock
as nominees will not have discretionary authority to vote shares with respect to
the Merger Agreement absent instructions from the beneficial owner thereof. The
proxy holders named in the enclosed proxy card will vote all shares of the
AmVestors Common Stock represented by proxy cards that are properly signed and
returned by stockholders in accordance with the instructions contained therein.
You may specify your voting choices by marking the appropriate boxes on the
proxy card. Shares as to which an executed proxy card is returned and the
stockholder has abstained from voting on any matter are considered shares
present at the AmVestors Special Meeting for purposes of determining a quorum
and are included in determining whether the proposals presented at the Special
Meeting are approved (I.E., an abstention would have the effect of a vote
against the Merger Agreement and the transactions contemplated thereby, and
against such other business as may have properly come before the AmVestors
Special Meeting, including adjournment or postponement thereof). On the other
hand, brokers do not have discretionary authority to vote on the approval and
adoption of the Merger Agreement as to shares held in street name, and
therefore, if an executed proxy card is returned by a broker holding shares of
AmVestors Common Stock in street name such shares will be considered present at
the AmVestors Special Meeting for purposes of determining a quorum but will not
be voted with respect to such matter (which has the effect of voting against the
proposal). IF STOCKHOLDERS PROPERLY SIGN AND RETURN THEIR PROXY CARD, BUT DO NOT
SPECIFY THEIR VOTING CHOICES, THEIR SHARES WILL BE VOTED FOR ALL PROPOSALS AND
TO APPROVE AND ADOPT THE MERGER AGREEMENT AS RECOMMENDED BY THE AMVESTORS BOARD.
 
    The AmVestors Board is not aware of any matters other than those set forth
in the Notice of AmVestors Special Meeting of stockholders that may be brought
before the AmVestors Special Meeting. If any other matters properly come before
the AmVestors Special Meeting, including a motion to adjourn the AmVestors
Special Meeting for the purpose of soliciting additional proxies, the persons
named in the accompanying proxy will vote the shares represented by all properly
executed proxies on such matters in their discretion, except that shares
represented by proxies which have been voted "against" the Merger Agreement will
not be used to vote "for" adjournment of the AmVestors Special Meeting for the
purpose of allowing additional time for soliciting additional votes "for" the
Merger Agreement. See "--Revocability of Proxies."
 
REVOCABILITY OF PROXIES
 
    A stockholder may revoke a proxy at any time prior to its exercise by (i)
delivering to Lynn F. Hammes, Secretary, AmVestors Financial Corporation, 555
South Kansas Avenue, Topeka, Kansas 66603, a written notice of revocation prior
to the AmVestors Special Meeting, (ii) delivering, prior to the AmVestors
Special Meeting, a duly executed proxy bearing a later date, or (iii) attending
the AmVestors
 
                                       27
<PAGE>
Special Meeting and voting in person. The presence of a stockholder at the
AmVestors Special Meeting will not in and of itself automatically revoke such
stockholder's proxy.
 
SOLICITATION OF PROXIES
 
    AmVestors will bear the costs of solicitation of proxies from its
stockholders, except that AmVestors and AmerUs will share equally the cost of
printing this Joint Proxy Statement/Prospectus. In addition to solicitation of
proxies by mail, directors, officers and employees of AmVestors and its
subsidiaries, without receiving additional compensation therefor, may solicit
proxies by telephone, telefax, telegram or in person. Arrangements also will be
made with brokerage firms and other custodians, nominees and fiduciaries for the
forwarding of solicitation materials to the beneficial owners of stock held of
record by such persons and AmVestors will reimburse such brokerage firms,
custodians, nominees and fiduciaries for reasonable out-of-pocket expenses
incurred by them in connection therewith.
 
    Beacon Hill Partners, Inc. ("BEACON HILL"), a professional soliciting
organization, will assist in the solicitation of proxies by AmVestors. Beacon
Hill's fee for solicitation of the proxies is estimated to be $7,500 plus
reimbursement for out-of-pocket costs and expenses.
 
    In addition, directors, officers and employees of AmerUs and its
subsidiaries may solicit proxies from AmVestors stockholders, without receiving
additional compensation therefor, by telephone, mail, telefax, telegram or in
person.
 
ADJOURNMENT OF THE AMVESTORS SPECIAL MEETING
 
    A vote (i) in person by a stockholder for adjournment of the AmVestors
Special Meeting, or (ii) for the last proposal on the proxy card authorizing the
named proxies to vote the shares covered by such proxy in their discretion with
respect to such other business as may properly come before the AmVestors Special
Meeting, which would allow such named proxies in their discretion to vote to
adjourn the AmVestors Special Meeting, would allow for additional solicitation
of stockholder votes in order to obtain a quorum or in order to obtain more
votes in favor of the Merger Agreement. The AmVestors Board unanimously
recommends that the stockholders vote in person in favor of any adjournment of
the AmVestors Special Meeting so suggested by the AmVestors Board in order to
solicit additional votes in order to obtain a quorum or to obtain more votes in
favor of the Merger Agreement, or in favor of the last proposal on its
respective proxy card. See "--Vote Required" for the effect of abstentions and
broker non-votes with respect to a vote on a proposal to adjourn the AmVestors
Special Meeting and on such other proposals.

                                   THE MERGER
 
GENERAL
 
    The discussion in this Joint Proxy Statement/Prospectus of the Merger and
the description of the Merger Agreement's principal terms are subject to and
qualified in their entirety by reference to the Merger Agreement, a copy of
which is attached to this Joint Proxy Statement/Prospectus as Annex I.
 
BACKGROUND OF THE MERGER
 
    The AmVestors Board has from time to time considered various corporate
strategies designed to increase long-term stockholder value in recognition of
the increasing importance of scale in the financial services industry. In 1993
the AmVestors Board set a goal to double assets under management over the next
three years, to $4.0 billion by December 31, 1996. In connection therewith,
AmVestors embarked on a strategy of growth which included pursuing acquisitions
of annuity companies, such as its acquisition of Financial Benefit Group, Inc.
("FBG") in April 1996, and blocks of annuity contracts. In addition, AmVestors
continued its emphasis on selling the full range of fixed rate individual
annuity products through existing agency relationships, and expanding such
relationships. By December 31, 1996, AmVestors had approximately $3.3 billion of
assets under management, well below its $4.0 billion goal, and senior management
at AmVestors became concerned with AmVestors' lack of sufficient resources to
successfully pursue an acquisition-based growth strategy. At the meetings of the
AmVestors Board on March 27, 1997 and June 10, 1997, this issue was discussed,
among other things, and the AmVestors Board concluded that while AmVestors had
experienced annual growth in premiums during 1993-1996 and year-to-date 1997,
because of its relative size, its prospects for continued growth in an
increasingly consolidating and competitive industry warranted consideration of
the feasibility of strategic alternatives in order to significantly enhance
stockholder value. At its March 27, 1997 meeting, the AmVestors Board retained
Goldman Sachs & Co. ("GOLDMAN SACHS") as financial advisor and Bush-O'Donnell &
Co., Inc. ("BUSH-O'DONNELL") as special advisor to advise AmVestors' management
in its exploration of strategic alternatives.
 
    Soon after the March 27, 1997 AmVestors Board meeting, another insurance
company expressed interest to AmVestors regarding a potential strategic
combination and preliminary discussions were held between management of
AmVestors and such other life insurance company. Such company entered into a
confidentiality agreement with AmVestors and conducted preliminary due diligence
of AmVestors during May 1997, but such discussions did not result in a specific
transaction proposal and such company indicated that it was no longer interested
in a transaction and withdrew.
 
    On June 10, 1997, the AmVestors Board met with Goldman Sachs and legal
counsel and discussed the withdrawal of the other insurance company and
authorized Goldman Sachs to begin a general solicitation of interest in the
market on behalf of AmVestors in an acquisition of or other strategic
transaction with AmVestors.
 
    Beginning June 11, 1997, Goldman Sachs began such solicitation and made
initial contact with 65 potential acquirors on behalf of AmVestors.
Approximately half of these companies expressed interest in receiving
confidential information, including AmerUs. Following execution of
confidentiality agreements, including customary standstill and certain other
provisions, these potential acquirors were sent an offering memorandum and
actuarial appraisal of AmVestors insurance subsidiaries. AmerUs executed such a
confidentiality agreement on June 19, 1997 and received an offering memorandum
and actuarial appraisal. Subsequently, these potential acquirors were invited by
Goldman Sachs on behalf of AmVestors to submit written, non-binding indications
of interest, in accordance with certain procedures, to acquire or combine with
AmVestors. Five of these companies (including AmerUs) submitted formal
indications of interest, and were invited to conduct detailed due diligence of
AmVestors. After a review of the offering memorandum and an initial analysis of
the value of AmVestors prepared by AmerUs management, AmerUs submitted a
non-binding indication of interest on July 11, 1997.
 
    On July 22, 1997, AmVestors publicly announced that it had retained Goldman
Sachs to assist it in exploring its strategic alternatives. On August 1, 1997,
Goldman Sachs distributed final bid instructions
 
                                       29
<PAGE>
to four of these companies, each of which was invited to continue due diligence
on AmVestors and following that to indicate the terms and conditions on which
they might propose to enter into a business combination with AmVestors. At this
time, AmerUs retained Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ") to assist it in evaluating a transaction with AmVestors.
 
    Pursuant to the procedures established, on July 28 and 29, 1997 certain
representatives of AmerUs and their advisors conducted initial due diligence on
AmVestors and met with the senior management of AmVestors including Mr. Ralph W.
Laster, Jr., Chairman and Chief Executive Officer of AmVestors, and Mr. Mark V.
Heitz, President and General Counsel of AmVestors. The AmerUs representatives
included Mr. Michael E. Sproule, Executive Vice President and Chief Financial
Officer, Mr. Michael G. Fraizer, Senior Vice President and Treasurer of AmerUs,
and certain other officers of AmerUs.
 
    Between August 1 and August 28, 1997 each of the four companies that had
been invited to conduct further due diligence on AmVestors communicated to
Goldman Sachs various terms and conditions on which they might propose to enter
into a business combination with AmVestors.
 
    Following an extensive evaluation of the operations and financial condition
of AmVestors based upon the materials provided and the results of due diligence,
AmerUs on August 26, 1997, submitted its initial firm proposal for a strategic
combination of AmerUs and AmVestors. Under the proposal, each share of AmVestors
Common Stock would be converted into the right to receive a number of shares of
AmerUs Class A Common Stock valued at $19.00. In addition, AmVestors
shareholders would have had the right to elect to receive $19.00 in cash for
each share, provided that not more than 30% of the total consideration would be
paid in cash. Collar provisions which would allow AmVestors shareholders to
share in the upside potential of AmerUs stock were also offered.
 
    On August 28, 1997 the AmVestors Board met, together with Goldman Sachs and
legal counsel, to discuss the results of the solicitation process and the
initial AmerUs proposal. At such meeting, the AmVestors Board reviewed with
Goldman Sachs the possible terms of a business combination which were
communicated by the companies that conducted further due diligence on AmVestors.
The AmVestors Board considered with respect to such companies and the terms
which they had communicated, among other factors, the type and amount of
consideration proposed and such companies' respective financial status,
prospects and reputation. Based upon such considerations, including its belief
that the initial AmerUs proposal was likely to yield to AmVestors stockholders
the most attractive amount and type of consideration, the AmVestors Board
authorized management of AmVestors to pursue further negotiations with AmerUs.
Pursuant to subsequent telephone negotiations between AmVestors and AmerUs, the
terms and conditions of the AmerUs proposal were modified to include a variable
number of shares of AmerUs Class A Common Stock, subject to a maximum and
minimum number, based upon a range of trading prices which would be used to
determine the number of shares of AmerUs Class A Common Stock into which each
share of AmVestors Common Stock would be converted.
 
    Subsequent to AmerUs' initial proposal and prior to execution of the
definitive Merger Agreement, another company, (one of the companies first
solicited in June which did not submit a preliminary indication of interest)
expressed interest in a possible strategic transaction with AmVestors. After
entering into a confidentiality agreement, this company conducted detailed due
diligence of AmVestors, but did not submit a definitive proposal.
 
    On August 29, 1997, Goldman Sachs on behalf of AmVestors informed AmerUs
that AmVestors was interested in a stock transaction and might consider a
similar but enhanced offer. Various telephone discussions ensued between AmerUs,
AmVestors, and representatives of their respective financial advisors during the
following weekend. The participants included Mr. Roger K. Brooks, Chairman,
Chief Executive Officer and President of AmerUs, Mr. Joseph K. Haggerty, Senior
Vice President and General Counsel of AmerUs, Messrs. Sproule, Laster and Heitz
as well as Mr. James O'Donnell, a director of AmVestors and a partner in
Bush-O'Donnell and representatives of their respective financial advisors. On
September 3, 1997, Messrs, Brooks, Sproule, Laster, Heitz, O'Donnell and
representatives of the respective financial advisors met to discuss the merits
of the proposal providing for a modified collar on the exchange ratios and total
stock consideration. The parties were unable to reach agreement at this
 
                                       30
<PAGE>
time. Subsequently, on September 5, 1997, AmerUs offered a per share
consideration with a variable number of shares of AmerUs Class A Common Stock,
subject to a maximum and minimum number, intended to be valued at at least
$20.00, and a $19.00 cash alternative for up to 30% of the total consideration.
Over the next several days, the details were refined by the representatives of
the parties. In further negotiations, the Termination for Price (as defined
below) was agreed upon, and the $19.00 cash alternative was eliminated.
 
    The AmerUs Board has provided AmerUs management with general authority to
consider and negotiate potential acquisitions, with the understanding that all
such actions would be subject to review and approval of the AmerUs Board.
Consistent with this practice, AmerUs management did not seek specific authority
to enter into negotiations concerning this transaction. On September 11, 1997,
AmerUs management initially contacted certain AmerUs directors to inform them of
the possibility of a transaction, the status of the negotiations and to solicit
questions and advice. On September 13, 1997, each of the directors of AmerUs was
sent material concerning the potential transactions with AmVestors including a
review of the proposed transaction and an overview of AmVestors and its
financial results, sales and distribution, investment portfolio and management,
the projected expense savings and summary appraisal analysis. From September 8
through September 18, 1997, AmVestors, AmerUs and their respective financial
advisors and counsel held several meetings in person and by telephone to
negotiate the various terms and conditions of the definitive Merger Agreement
and to conduct due diligence with respect to each other. These discussions led
to the definitive Merger Agreement.
 
    On September 17, 1997, a special meeting of the AmerUs Board was held to
discuss various aspects of the proposed merger with AmVestors. Members of AmerUs
management discussed with the AmerUs Board the proposal to acquire AmVestors
including (1) a description of AmVestors' business, financial condition,
distribution systems, investment portfolio and management; (2) details of
potential expense savings and effects on earnings; and (3) a summary of major
terms of the proposed Merger Agreement. Representatives of DLJ and Fox-Pitt,
Kelton Inc. ("FOX-PITT, KELTON"), a special advisor retained by AmerUs in
September 1997, also reviewed their analysis of the proposed transaction,
including its financial terms. At the conclusion of the meeting, the AmerUs
Board authorized management to finalize the documentation for the proposed
transaction in preparation for a special AmerUs Board meeting scheduled for
September 19, 1997.
 
    On September 19, 1997, the AmVestors Board held a full day special special
meeting to review, with the advice and assistance of its financial and legal
advisors, the proposed Merger Agreement and the transactions contemplated
thereby. At such meeting, AmVestors' management and financial and legal advisors
made presentations to the AmVestors Board concerning such matters. After further
discussions with Goldman Sachs and the management of AmVestors, and having
compared the terms communicated by the three other companies that had conducted
further due diligence on AmVestors to those contained in the proposed Merger
Agreement, the AmVestors Board determined that the Merger Consideration offered
by AmerUs represented the highest price per share likely to be obtained for
AmVestors stockholders. Goldman Sachs rendered to the AmVestors Board its
written opinion to the effect that, as of such date, the Exchange Ratio pursuant
to the Merger Agreement was fair from a financial point of view to the holders
of AmVestors Common Stock. Following the AmVestors Board's review of the Merger
Agreement and the transactions contemplated thereby, including the Merger, the
AmVestors Board unanimously approved the proposed Merger Agreement and
transactions contemplated thereby, including the Merger, and authorized the
execution and delivery of the Merger Agreement.
 
    On September 19, 1997, the AmerUs Board held a special meeting and
considered the proposed Merger Agreement and the transactions contemplated
thereby, including the Stock Issuance. The Chairman reviewed developments since
the AmerUs Board meeting held on September 17, 1997. Members of AmerUs
management and its legal advisors made presentations concerning key elements of
the proposed transaction, including the financial assessment of AmVestors, pro
forma merger analysis, results of due diligence and legal considerations for the
AmerUs Board in discharging its fiduciary responsibilities in connection with
the proposed transaction, and the terms and conditions of the Merger Agreement
which had been negotiated. The AmerUs Board was advised of the financial aspects
of the
 
                                       31
<PAGE>
Merger by DLJ and was also provided a written opinion from DLJ that the Exchange
Ratio was fair to AmerUs from a financial point of view. Fox-Pitt, Kelton, an
investment banking firm which served as a financial advisor to AmerUs in
connection with the acquisition of Delta, did not submit a written opinion or
report to the Board, but did verbally review with the Board their observations
about AmVestors, including a comparison of its operation to Delta's, the reasons
underlying the success of the AmerUs offer and the potentially favorable market
reaction to the transaction. Based upon the information presented, the AmerUs
Board unanimously approved the Merger Agreement and determined that the Merger
and the Stock Issuance were in the best interests of AmerUs shareholders, and
recommended that the AmerUs shareholders vote for the Stock Issuance.
 
    Early in the evening on Friday, September 19, 1997, the Merger Agreement was
executed and delivered by all parties thereto, and on September 22, 1997,
AmVestors and AmerUs issued a joint press release announcing the Merger
Agreement.
 
CERTAIN AMVESTORS PROJECTED FINANCIAL INFORMATION AND ASSUMPTIONS
 
    During the course of due diligence of certain parties, including AmerUs,
relating to potential strategic transactions with AmVestors, AmVestors made
available to such parties certain financial projections and estimates prepared
by AmVestors management.
 
    AmVestors management utilized a top down approach to project financial
results using the following key assumptions. The projections assumed that
annuity premiums received would rise from approximately $514.4 million in 1997
to approximately $943.5 million in 2001. The projections were calculated
assuming level interest rates utilizing the December 31, 1996 yield curve.
Projected yields, calculated by dividing the sum of investment income and
realized gains by average cash and invested assets in the models, were assumed
to decline from 7.80% in 1997 to 7.66% in 2001 for FBL and to rise from 7.39% in
1997 to 7.47% in 2001 for American. Realized gains include the difference
between AmVestors' expected returns (based on historical results) on convertible
stocks and bonds and the coupon/dividend income from these securities. The
projections assume that throughout 1997 American and FBL's holdings of
convertible securities are increased to approximately 5% of invested assets.
Generally, no allowance has been made for default losses. AmVestors has not
experienced a default loss since 1991.
 
    AmVestors' current interest crediting strategy is utilized as the beginning
crediting strategy for the projections. The projections assume that credited
rates are reduced 25 basis points on American's business in 1998. The average
credited interest rates generated in the models by the assumed crediting
strategy were assumed to rise from 4.89% in 1997 to 5.23% in 2001 for FBL and to
decline from 5.59% in 1997 to 5.35% in 2001 for American.
 
    Surrender assumptions contained in the projections represent management's
best estimate of full, partial and free withdrawals. These assumptions were
developed with full consideration to historical results of the existing inforce
business.
 
    The average surrender rates, calculated as a percentage of average policy
reserves, were assumed to decline from 17.90% in 1997 to 16.92% in 2001 for FBL
and to decline from 16.09% in 1997 to 15.48% in 2001 for American (including
deaths, full, partial and free surrenders).
 
    Total fixed maintenance costs were assumed to be constant. All projections
assume a 35% effective federal tax rate in all years.
 
    Based upon the foregoing assumptions and qualifications, the projected total
assets for AmVestors were estimated to rise from approximately $3.6 billion in
1997 to approximately $5.2 billion in 2001, total revenue was estimated to rise
from approximately $238.1 million in 1997 to approximately $343.0 million in
2001, and net earnings were estimated to rise from approximately $24.6 million
in 1997 to approximately $37.2 million in 2001.
 
    AmVestors does not as a matter of course make public any projections as to
future performance or earnings, and the projections set forth above are included
in this Joint Proxy Statement/Prospectus only because the information was
provided to AmerUs. The projections were not prepared with a view to
 
                                       32
<PAGE>
public disclosure or compliance with the published guidelines of the American
Institute of Certified Public Accountants regarding prospective financial
information. AmVestors' internal operating projections are, in general, prepared
solely for internal use in connection with budgeting and other management
decisions and are subjective in many respects and thus susceptible to various
interpretations and periodic revisions based on actual experience and business
developments. The projections were based on a number of material assumptions
specified therein and summarized above. These assumptions are beyond the control
of AmVestors, AmerUs and Merger Sub or their respective financial advisors, and
require a degree of economic forecasting that is inherently uncertain and
subjective. None of AmVestors, AmerUs or Merger Sub or their respective
financial advisors assumes any responsibility for the accuracy of any of the
projections. Neither AmVestors' independent auditors, nor any other independent
accountants or financial advisors, have compiled, examined or performed any
procedures with respect to the prospective financial information contained
herein, nor have they expressed any opinion or any form of assurance on such
information or its achievability, and assume no responsibility for, and disclaim
any association with, the prospective financial information. The inclusion of
the foregoing projections should not be regarded as an indication that
AmVestors, AmerUs or Merger Sub or any other person who received such
information considers it an accurate prediction of future events. AmerUs and
Merger Sub can provide no assurance whatsoever as to either the accuracy or
completeness of such projected financial statements or as to whether the
assumptions identified by AmVestors management relating thereto were reasonable.
Neither AmVestors nor AmerUs intends to update, revise or correct such
projections if they become inaccurate (even in the short term).
 
AMERUS' REASONS FOR THE MERGER AND THE STOCK ISSUANCE; RECOMMENDATION OF THE
  AMERUS BOARD
 
    At a meeting of the AmerUs Board (with one member absent) held on September
19, 1997, members of AmerUs' management and representatives of DLJ and Fox-Pitt,
Kelton made presentations concerning the business and prospects of AmVestors and
the potential combination of AmVestors and AmerUs. The AmerUs Board also
received presentations concerning, and reviewed the terms of, the Merger
Agreement with members of AmerUs' management, its legal counsel and financial
advisors. At the meeting, the AmerUs Board unanimously determined that the Stock
Issuance and the Merger, upon the terms and conditions set forth in the Merger
Agreement, are fair to, and in the best interests of, the shareholders of
AmerUs. Accordingly, the AmerUs Board has unanimously approved the Stock
Issuance and the Merger Agreement and unanimously recommends that the holders of
outstanding shares of AmerUs Common Stock vote for approval of the Stock
Issuance at the AmerUs Special Meeting. See "--Background of the Merger."
 
    In reaching its determination, the AmerUs Board consulted with AmerUs'
management, as well as its financial advisors and legal counsel, and considered
the following material factors:
 
    (i) The expectation that the Merger would provide important strategic
benefits, including:
 
        (a) expansion of AmerUs' presence in the rapidly growing asset
    accumulation business, which involves seeking and actively managing
    policyholder funds through insurance and annuity products;
 
        (b) enhancement of the breadth and diversity of AmerUs' distribution
    network;
 
        (c) increased potential for significant cross-selling efficiencies and
    expense savings opportunities; and
 
        (d) the complementary fit with the recent acquisition of Delta.
 
    (ii) The opportunity for earnings accretion (as described under "--Opinion
of the Financial Advisor to the AmerUs Board--Pro Forma Merger Analysis") and
reduction in expenses, including anticipated cost savings of $6-8 million in
1998 and additional amounts thereafter.
 
    (iii) The expectation that because of the issuance of additional shares of
AmerUs Class A Common Stock to acquire AmVestors (with the number outstanding
and held by the public estimated at between
 
                                       33
<PAGE>
approximately 17.9 and 19.1 million vs. 6.4 million for AmerUs as of September
19, 1997), the AmerUs Class A Common Stock would have increased market float and
greater liquidity.
 
    (iv) The presentations of DLJ delivered to the AmerUs Board on September 17
and 19, 1997, including DLJ's comparison of the calculated values of the Merger
Consideration of $20 per share to the median values described below under each
of the sections "Opinion of Financial Advisor to the AmerUs Board--Transaction
Analysis and Public Company Analysis" and DLJ analyses set forth under "Opinion
of Financial Advisor to the AmerUs Board--Stock Trading History, Pro Forma
Merger Analysis and Contribution Analysis"; and DLJ's written opinion to the
effect that as of such date the Exchange Ratio was fair to AmerUs from a
financial point of view. A copy of such opinion is attached to this Joint Proxy
Statement/Prospectus as Annex II. See "--Opinion of the Financial Advisor to the
AmerUs Board."
 
    (v) The terms and conditions of the Merger Agreement (including the fact
that under certain circumstances, AmVestors must pay AmerUs a termination fee of
up to $10.8 million in connection with the termination of the Merger Agreement
(See "THE MERGER AGREEMENT--Termination", "--Fees and Expenses")), which the
AmerUs Board, based on presentations by its legal and financial advisors, deemed
to be generally favorable to AmerUs, as well as the belief that approval of the
Merger Agreement and the Stock Issuance was consistent with the AmerUs Board's
fiduciary duties as described by its legal advisors.
 
    (vi) AmVestors projected financial information and assumptions,
substantially as described in the preceding section.
 
    (vii) The analysis and recommendation of the Merger by AmerUs' management,
including, without limitation, a discussion of the foregoing factors.
 
    From the information and advice provided by management and its advisers on
the operational and strategic benefits of the acquisition in the annuity market
and the potential for a positive financial impact, the AmerUs Board believes
that the acquisition of AmVestors is a financially and operationally sound step
in its overall strategy of growing the company and increasing its resources and
that it is in the best interests of AmerUs and its shareholders.
 
    The foregoing discussion of information and factors considered and given
weight by the AmerUs Board is not intended to be exhaustive. In view of the wide
variety of factors considered in connection with its evaluation of the terms of
the Merger, the AmerUs Board did not find it practicable to, and did not,
quantify or otherwise attempt to assign relative weights to the specific factors
considered in reaching their determinations. In addition, individual members of
the AmerUs Board may have given different weights to different factors. For
additional information concerning anticipated cost savings and estimated number
of shares held by the public referenced above, see "AMERUS LIFE HOLDINGS, INC.,
DELTA LIFE CORPORATION AND AMVESTORS FINANCIAL CORPORATION PRO FORMA CONDENSED
CONSOLIDATED FINANCIAL INFORMATION".
 
    THE AMERUS BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF AMERUS COMMON STOCK
VOTE FOR APPROVAL OF THE STOCK ISSUANCE.
 
OPINION OF THE FINANCIAL ADVISOR TO THE AMERUS BOARD
 
    In its role as financial advisor to AmerUs, DLJ was asked by AmerUs to
render its opinion to the AmerUs Board as to the fairness from a financial point
of view to AmerUs of the consideration to be paid by AmerUs pursuant to the
terms of the Merger Agreement. AmerUs engaged DLJ to provide its fairness
opinion based upon DLJ's qualifications, expertise and reputation as well as
DLJ's prior investment banking relationship and familiarity with AmerUs. On
September 19, 1997, DLJ delivered its written opinion (the "DLJ OPINION") to the
effect that as of the date of such opinion and based upon and subject to the
assumptions, limitations and qualifications set forth in such opinion, the
Exchange Ratio was fair to AmerUs from a financial point of view.
 
                                       34
<PAGE>
    A COPY OF THE DLJ OPINION IS ATTACHED HERETO AS ANNEX II. AMERUS
SHAREHOLDERS ARE URGED TO READ THE OPINION IN ITS ENTIRETY FOR ASSUMPTIONS MADE,
PROCEDURES FOLLOWED, OTHER MATTERS CONSIDERED AND LIMITS OF THE REVIEW BY DLJ.
 
    The DLJ Opinion was prepared for the AmerUs Board and is directed only to
the fairness from a financial point of view to AmerUs, and does not constitute a
recommendation to any AmerUs shareholder as to how to vote at the AmerUs Special
Meeting. The DLJ Opinion does not constitute an opinion as to the price at which
AmerUs Class A Common Stock will actually trade at any time. The type and amount
of Merger Consideration was determined in arms' length negotiations between
AmerUs and AmVestors, in which negotiations DLJ advised AmerUs. No restrictions
or limitations were imposed by the AmerUs Board upon DLJ with respect to the
investigations made or the procedures followed by DLJ in rendering its opinion.
 
    In arriving at its opinion, DLJ reviewed the Merger Agreement. DLJ also
reviewed financial and other information that was publicly available or
furnished to it by AmerUs and AmVestors, including information provided during
discussions with their respective managements. Included in the information
provided during discussions with the respective managements were certain
financial projections of AmVestors for the period beginning January 1, 1997 and
ending December 31, 2001 prepared by the management of AmVestors, as well as
certain financial projections of AmerUs, pro forma for the acquisition of Delta,
for the period beginning January 1, 1997 and ending December 31, 1999 prepared
by the management of AmerUs. In addition, DLJ compared certain financial and
securities data of AmerUs and AmVestors with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of AmerUs Class A Common Stock and AmVestors Common Stock,
reviewed prices and premiums paid in certain other business combinations and
conducted such other financial studies, analyses and investigations as DLJ
deemed appropriate for purposes of rendering the DLJ Opinion.
 
    In rendering its opinion, DLJ relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
it from public sources, that was provided to it by AmerUs and AmVestors or their
respective representatives, or that was otherwise reviewed by it. In particular,
DLJ relied upon the estimates of the management of AmerUs of the operating
synergies achievable as a result of the Merger. With respect to the financial
projections supplied to it by AmVestors, DLJ assumed that they were reasonably
prepared on the basis reflecting the best currently available estimates and
judgments of the management of AmVestors as to the future operating and
financial performance of AmVestors. With respect to the financial projections
supplied to it by AmerUs, DLJ assumed that they were reasonably prepared on the
basis reflecting the best currently available estimates and judgments of the
management of AmerUs as to the future operating and financial performance of
AmerUs. DLJ did not assume any responsibility for making an independent
evaluation of any assets or liabilities or for making any independent
verification of any of the information reviewed by it.
 
    The DLJ Opinion is necessarily based on economic, market, financial and
other conditions as they existed on, and on the information made available to
DLJ as of September 19, 1997. It should be understood that, although subsequent
developments may affect the DLJ Opinion, DLJ does not have any obligation to
update, revise or reaffirm the DLJ Opinion.
 
    The following is a summary of the presentation made by DLJ to the AmerUs
Board at its September 19, 1997 meeting.
 
    TRANSACTION ANALYSIS.  DLJ reviewed publicly available information for
selected transactions completed since 1992 involving the acquisition of annuity
companies (the "SELECTED ANNUITY TRANSACTIONS") and the acquisition of life
insurance and annuity companies (the "SELECTED LIFE AND ANNUITY TRANSACTIONS")
(together, the "SELECTED TRANSACTIONS"). In reviewing the Selected Transactions,
several factors were considered, including: (i) the lack of publicly available
information for subsidiary and private company transactions which represent a
significant portion of the relevant merger and acquisition activity; and (ii)
the lack of directly comparable transactions. The Selected Transactions were not
intended to represent the complete list of annuity company transactions or life
insurance and annuity company transactions which have occurred. Such
transactions were used in this analysis because the companies involved were
deemed by DLJ to operate in similar businesses or have similar financial
characteristics to AmVestors.
 
                                       35
<PAGE>
    DLJ reviewed the consideration paid in the Selected Transactions in terms of
the price paid for the common stock in the Selected Transactions as a multiple
of GAAP operating earnings for the latest reported twelve month period ("LTM")
ended prior to the announcement of such transactions and as a multiple of
shareholders' equity for the latest fiscal quarter ("LFQ") ended prior to the
announcement of such transactions. In analyzing acquisitions of life insurance
and annuity companies, the purchase price paid may be described in terms of
multiples of the price paid for common stock to GAAP operating earnings and to
shareholders' equity. Variances in multiples for different transactions may
reflect such considerations as the consistency, quality and growth of earnings
and the company's capitalization, asset quality and return on capital. Since
GAAP operating earnings and shareholders' equity already reflect the cost of a
company's debt or preferred stock financing, analyses of multiples of GAAP
operating earnings or shareholders' equity are usually based on the price paid
for the company's common stock, which excludes the cost of assuming, repaying or
redeeming such debt or preferred stock financing. Comparing the multiples of the
Merger Consideration to the GAAP operating earnings and stockholders' equity of
AmVestors with multiples paid by acquirers in other transactions indicates
whether the valuation being placed on AmVestors is within the range of values
paid for other life insurance and annuity companies.
 
    The low, average and high multiples of price paid for common stock to LTM
GAAP operating earnings were 7.7x, 16.4x and 36.6x, respectively, for the
Selected Annuity Transactions and 10.4x, 17.0x and 26.9x, respectively, for the
Selected Life and Annuity Transactions. Based on Merger Consideration of $20.00
per share, the implied multiple of Merger Consideration to AmVestors' GAAP
operating earnings for the LTM ended June 30, 1997 was 13.6x. This multiple is
between the low and average multiples of both the Selected Annuity Transactions
and the Selected Life and Annuity Transactions. The low, average and high
multiples of price paid for common stock to stockholders' equity as of the end
of the LFQ ended prior to the announcement of the transaction were 0.9x, 1.4x
and 2.7x, respectively, for the Selected Annuity Transactions and 0.9x, 1.5x and
2.7x, respectively, for the Selected Life and Annuity Transactions. Based on
Merger Consideration of $20.00 per share, the implied multiple of Merger
Consideration to AmVestors' stockholders' equity as of June 30, 1997 was 1.3x.
This multiple is between the low and average multiples of both the Selected
Annuity Transactions and the Selected Life and Annuity Transactions.
 
    DLJ determined the percentage premium of the offer prices (represented by
the purchase price per share in cash transactions and the price of the
constituent securities multiplied by the exchange ratio in the case of
stock-for-stock mergers) over the public market trading prices one day, one week
and one month prior to the announcement date for selected transactions involving
annuity companies where the acquired company's stock was publicly traded (the
"SELECTED PUBLIC ANNUITY TRANSACTIONS") and for selected transactions involving
life insurance and annuity companies where the acquired company's stock was
publicly traded (the "SELECTED PUBLIC LIFE AND ANNUITY TRANSACTIONS"). The
average premiums of offer prices to public market trading prices one day, one
week and one month prior to the announcement date were 15.4%, 17.2% and 26.9%,
respectively, for the Selected Public Annuity Transactions and 17.0%, 18.4% and
26.2%, respectively, for the Selected Public Life and Annuity Transactions.
Merger Consideration of $20.00 per share represents discounts to the trading
prices of AmVestors Common Stock one day, one week and one month prior to
September 17, 1997 of 24.4%, 15.0% and 11.9%, respectively. These discounts are
lower than the corresponding average premiums of the Selected Public Annuity
Transactions and the Selected Public Life and Annuity Transactions. Merger
Consideration of $20.00 per share represents premiums to the trading prices of
AmVestors Common Stock one day, one week and one month prior to the July 22,
1997 announcement that AmVestors was exploring strategic alternatives, including
a sale, of 1.9%, 2.2% and 11.1%, respectively. These premiums are lower than the
corresponding average premiums of the Selected Public Annuity Transactions and
the Selected Public Life and Annuity Transactions.
 
    PUBLIC COMPANY ANALYSIS.  To provide comparative market information, DLJ
compared selected historical and projected operating and financial ratios of
AmVestors to the corresponding data and ratios
 
                                       36
<PAGE>
of selected annuity companies whose securities are publicly traded. Such
companies included American Annuity Group Inc., Life USA Holding Inc. and
Presidential Life Corp. (the "SELECTED SMALL CAPITALIZATION ANNUITY COMPANIES")
as well as Liberty Financial Companies, Nationwide Financial Services, Inc.,
ReliaStar Financial Corp. and SunAmerica, Inc. (the "SELECTED LARGE
CAPITALIZATION ANNUITY COMPANIES") (together, the "SELECTED ANNUITY COMPANIES").
 
    Such analysis included, among other things, the ratios of stock price to
GAAP operating earnings per share ("EPS") for the LTM ended June 30, 1997,
estimated GAAP operating EPS for 1997 and 1998 (as compiled by Institutional
Brokers Estimating Service for the Selected Annuity Companies) and shareholders'
equity per share as of June 30, 1997. Closing stock prices as of September 17,
1997 were used in this analysis. The ratios described in this paragraph have
been designed to reflect the value attributable in the public equity markets to
various valuation measures of annuity companies. Measures utilized in the public
marketplace to value the stock of publicly traded companies in the annuity
industry are based on, among other things, a company's historical and projected
GAAP operating earnings as well as shareholders' equity. The multiples of stock
price to GAAP operating EPS reflect the value attributed to a company by public
equity market investors based on the company's historical and projected
earnings. The multiples of stock price to shareholders' equity per share reflect
the values attributed to a company by public equity market investors based on
the company's net worth. Variances in multiples for different companies may
reflect such considerations as the consistency, quality and growth of earnings
and the company's capitalization, asset quality and return on capital. Since
GAAP operating earnings and shareholders' equity already reflect the cost of a
company's debt or preferred stock financing, analyses of multiples of GAAP
operating earnings or shareholders' equity are usually based on the price paid
for the company's common stock, which excludes debt or preferred stock
financing. Comparing the multiples of the Merger Consideration to the GAAP
operating EPS and shareholders' equity of AmVestors with the multiples at which
the Selected Annuity Companies trade indicates whether the valuation being
placed on AmVestors pursuant to the Merger Consideration is within the range of
values at which the Selected Annuity Companies trade.
 
    The low, average and high multiples of public stock price to GAAP operating
EPS for the LTM ended June 30, 1997 were 14.0x, 14.4x and 15.0x, respectively,
for the Selected Small Capitalization Annuity Companies and 14.7x, 16.8x and
21.7x, respectively, for the Selected Large Capitalization Annuity Companies.
Based on Merger Consideration of $20.00 per share, the implied multiple of offer
price to AmVestors' GAAP operating EPS for the LTM ended June 30, 1997 was
13.6x. This multiple is lower than the low multiples of both the Selected Small
Capitalization Annuity Companies and the Selected Large Capitalization Annuity
Companies. The low, average and high multiples of public stock price to
estimated 1997 GAAP operating EPS were 13.8x, 14.7x and 15.4x, respectively, for
the Selected Small Capitalization Annuity Companies and 14.3x, 16.2x and 20.5x,
respectively, for the Selected Large Capitalization Annuity Companies. Based on
Merger Consideration of $20.00 per share, the implied multiple of offer price to
AmVestors' estimated 1997 GAAP operating EPS was 12.4x. This multiple is lower
than the low multiples of both the Selected Small Capitalization Annuity
Companies and the Selected Large Capitalization Annuity Companies. The low,
average and high multiples of public stock price to estimated 1998 GAAP
operating EPS were 12.6x, 13.1x and 13.8x, respectively, for the Selected Small
Capitalization Annuity Companies and 12.9x, 14.1x and 17.3, respectively, for
the Selected Large Capitalization Annuity Companies. Based on Merger
Consideration of $20.00 per share, the implied multiple of offer price to
AmVestors' estimated GAAP operating EPS for 1998 was 10.9x. This multiple is
lower than the low multiples of both public stock price to estimated 1998 GAAP
operating EPS of the Selected Small Capitalization Annuity Companies and the
Selected Large Capitalization Annuity Companies. The low, average and high
multiples of public stock price to stockholders' equity per share as of June 30,
1997 were 1.54x, 1.92x and 2.24x, respectively, for the Selected Small
Capitalization Annuity Companies and 1.46x, 2.47x and 3.75x, respectively, for
the Selected Large Capitalization Annuity Companies. Based on Merger
Consideration of $20.00 per share, the implied multiple of offer price to
AmVestors' stockholders' equity per share as of June 30, 1997 was 1.30x. This
multiple is lower than the low multiples of both the Selected Small
Capitalization Annuity Companies and the Selected Large Capitalization Annuity
Companies.

    No company or transaction used in the transaction analysis or the public
company analysis described above was directly comparable to the proposed Merger
or AmVestors. Accordingly, an analysis of the results of the foregoing was not
simply mathematical nor necessarily precise; rather, it involved complex
considerations and judgments concerning differences in financial and operating
characteristics of companies and other factors that could affect the transaction
values and trading prices. For example, many qualitative factors are involved in
valuing a company or analyzing a transaction in the life insurance and annuity
industries, including assessments of the quality of management, the
attractiveness of the company's target market, the economics of the products
being sold and the company's market position relative to its competitors. Other
factors that could affect the transaction values or trading prices include
differences in distribution, products, geographic or demographic customer
concentration, size, accounting practices, asset portfolio quality, interest
rate sensitivity and other factors. These factors may affect the transaction
values or trading prices in each case by affecting in varying degrees investors'
expectations of such factors as the company's risk and future operating
profitability.
 
    STOCK TRADING HISTORY.  To provide contextual data and comparative market
data, DLJ examined the history of the trading prices and their relative
relationships for AmVestors Common Stock for various periods ended prior to
September 17, 1997. DLJ also reviewed the daily closing prices of AmVestors
Common Stock and compared the AmVestors stock prices with the indices of the
Selected Annuity Companies. In addition, DLJ reviewed the trading history of
AmVestors Common Stock relative to indices of the Selected Annuity Companies in
order to assess the relative stock price performance of AmVestors and such
indices.
 
    PRO FORMA MERGER ANALYSIS.  DLJ analyzed certain pro forma financial effects
resulting from the Merger. In conducting its analysis, DLJ relied upon certain
assumptions described above and financial projections provided by the
managements of AmVestors and AmerUs. DLJ analyzed the pro forma effect of the
Merger on the EPS, stockholders' equity per share, leverage ratios and ownership
of AmerUs. AmerUs' management has indicated that it believes that the Merger
will offer consolidation opportunities which will result in revenue enhancements
and expense savings (together, "SYNERGIES") relative to the stand-alone
projected revenues and expenses of AmVestors and AmerUs. DLJ incorporated
estimates of such synergies provided by the management of AmerUs in its
analysis, although DLJ did not express any opinion as to the likelihood of such
synergies being realized. The results of the pro forma merger analysis are not
necessarily indicative of future operating results or financial position. Based
on these assumptions and on a range of Average AmerUs Share Prices and assuming
all AmVestors options and warrants are converted into comparable AmerUs
securities, AmerUs' shareholders would realize EPS accretion in 1998 and 1999,
and AmerUs' shareholders would realize shareholders' equity per share accretion
as of June 30, 1997. Based on these assumptions and assuming all AmVestors
options and warrants are converted into comparable AmerUs securities and
assuming Average AmerUs Share Prices of $27.00 and $29.75 per share, AmerUs'
ratios of debt and preferred stock to total capitalization as of June 30, 1997
would be 26.2% assuming the Merger is completed. Based on these assumptions and
assuming all AmVestors options and warrants are converted into comparable AmerUs
securities and assuming Average AmerUs Share Prices of $27.00 and $29.75 per
share, AmerUs' shareholders would have pro forma aggregate ownership of the
combined company of 63.5% and 65.6%, respectively. There can be no assurance as
to whether the assumptions regarding financial sources set forth in this
paragraph will occur, and such assumptions are used only for purposes of
illustration.
 
    CONTRIBUTION ANALYSIS.  DLJ analyzed AmVestors' and AmerUs' relative
contributions to the combined company with respect to pro forma ownership, 1998
estimated GAAP net income, 1999 estimated GAAP net income, total assets and
total shareholders' equity as of June 30, 1997 and compared this with the
relative ownership of AmerUs shareholders in the combined company after the
Merger. Such analysis was considered on a percentage contribution basis and was
made, where appropriate, with respect to estimated GAAP operating earnings for
1998 and 1999, as projected by AmVestors' and AmerUs' managements and not
reflecting any accounting adjustments related to the Merger or any synergies
expected to result from the Merger.
 
                                       38
<PAGE>
    AmVestors' relative contribution to the combined company with respect to pro
forma ownership is 34.4% of the total assuming an average AmerUs share price of
$29.75. AmVestors' relative contribution to the combined company with respect to
1998 and 1999 estimated GAAP net income is 31.7% and 30.3%, respectively, of the
total. AmVestors' relative contribution to total assets was 34.8% of the total.
AmVestors' relative contribution to shareholders' equity as of June 30, 1997 was
30.5% of the total. The results of these contribution analyses are not
necessarily indicative of the contributions that the respective businesses may
actually make in the future.
 
    The summary set forth above does not purport to be a complete description of
the analyses performed by DLJ, but describes, in summary form, the principal
elements of the presentation made by DLJ to the AmerUs Board on September 19,
1997. The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial analysis and the
application of these methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. Each of the
analyses conducted by DLJ was carried out in order to provide a different
perspective on the Merger and add to the total mix of information available. DLJ
did not form a conclusion as to whether any individual analysis, considered in
isolation, supported or failed to support an opinion as to fairness, from a
financial point of view. Rather, in reaching its conclusion, DLJ considered the
results of the analyses in light of each other and did not place particular
reliance or weight on any individual analysis and ultimately reached its opinion
based on the results of all analyses taken as a whole. Accordingly,
notwithstanding the separate factors summarized above, DLJ believes that its
analyses must be considered as a whole and that selected portions of its
analyses and the factors considered by it, without considering all analyses and
factors, may create an incomplete view of the evaluation process underlying the
DLJ Opinion. In performing its analyses, DLJ made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters. The analyses performed by DLJ are not necessarily indicative of actual
values or future results, which may be significantly more or less favorable than
suggested by such analyses.
 
    The AmerUs Board selected DLJ as its financial advisor because it is a
nationally recognized investment banking firm that has substantial experience in
transactions similar to the Merger and is familiar with AmerUs, its business and
the life insurance and annuity industries, as well as the fact that DLJ, as part
of its investment banking services, is regularly engaged in the valuation of
businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.
Pursuant to the terms of an engagement letter dated September 15, 1997 between
AmerUs and DLJ, AmerUs is to pay DLJ $500,000 for the rendering of the DLJ
Opinion and will pay DLJ, upon consummation of the Transaction, cash
compensation equal to $3,000,000, less the $500,000 payable pursuant to the
rendering of the DLJ opinion. AmerUs also agreed to reimburse DLJ for all
out-of-pocket expenses (including the reasonable fees and out-of-pocket expenses
of counsel) incurred by DLJ in connection with its engagement and to indemnify
DLJ and certain related persons against certain liabilities in connection with
its engagement, including liabilities under the federal securities laws. The
terms of the fee arrangement with DLJ, which DLJ and AmerUs believe are
customary in transactions of this nature, were negotiated at arms' length
between AmerUs and DLJ and the AmerUs Board was aware of such arrangement,
including the fact that a significant portion of the aggregate fee payable to
DLJ is contingent upon consummation of the Merger.
 
    In the ordinary course of business, DLJ may actively trade the securities of
both AmerUs and AmVestors for its own account and for the accounts of its
customers and, accordingly, may at any time hold a long or short position in
such securities. DLJ has performed investment banking and other services for
AmerUs in the past and has received usual and customary compensation for such
services. In January 1997, DLJ co-managed an initial public offering of AmerUs
common stock and received usual and customary underwriters compensation. In
addition, in April 1996, DLJ advised FBG, in its sale to AmVestors and received
usual and customary compensation for such services.
 
    Fox-Pitt, Kelton also presented orally its observations about the AmVestors
transaction to the Board. Fox-Pitt, Kelton compared the distinctive distribution
systems of both AmVestors and Delta. While noting
 
                                       39
<PAGE>
their differences it believed them to be complimentary. Fox-Pitt, Kelton also
stated that the relative size of AmVestors in the increasingly competitive and
consolidating annuity market, combined with the recent acquisitions in the fixed
annuity company sector by other potential purchasers, limited the number of
potential acquirers. However, the combination of AmVestors, Delta and AmerUs
Life created a competitive basis for the future because of the increased size of
the combined operations and because AmVestors has a demonstrated track record of
growth in the fixed annuity sector of the market. Lastly, Fox-Pitt Kelton
indicated it believed that the market would react favorably to the transaction
because of the recent market performance of AmVestors and because the
transaction reaffirmed the publicly stated acquisition strategy of AmerUs.
 
AMVESTORS' REASONS FOR THE MERGER; RECOMMENDATION OF THE AMVESTORS BOARD
 
    The AmVestors Board has unanimously approved the Merger Agreement and the
transactions contemplated thereby. The AmVestors Board believes that the Merger
will permit the stockholders of AmVestors to participate, through a tax-free
reorganization, in a combined company with greater financial resources,
diversification and ability to compete in a consolidating life insurance/annuity
products industry.
 
    In reaching its conclusion for such approval, the AmVestors Board consulted
with AmVestors senior management and financial and legal advisors and considered
many factors (at the September 19, 1997 Board meeting and at previous AmVestors
Board meetings), including, but not limited to, the following:
 
         (i) the presentations by management of AmVestors regarding the
    financial condition, results of operations, business and prospects of
    AmVestors;
 
        (ii) the Merger Consideration's premium over the $17.25 per share
    closing market price of AmVestors Common Stock on June 10, 1997, the date of
    the decision of the AmVestors Board to explore strategic alternatives
    (assuming the per share value of the Merger Consideration equals the minimum
    of $20.00, the Merger Consideration represents a 16% premium in comparison
    to such price (see "-- Opinion of the Financial Advisor to the AmVestors
    Board");
 
        (iii) the determination of the value of the Merger Consideration is such
    that (A) such value has the potential to increase over $20.00 per share of
    AmVestors Common Stock in the event that the AmerUs Stock Price is greater
    than $29.75 and (B) such value has the potential to decrease but cannot fall
    below $20.00 per share of AmVestors Common Stock without affording AmVestors
    the right to terminate the Merger Agreement and abandon the Merger (see
    "--Merger Consideration");
 
        (iv) certain pro forma financial information regarding the Merger,
    including the potential realization by AmVestors stockholders of a
    significant increase in rate of annual cash dividend without increasing
    their current investment (from $0.12 per AmVestors share to $0.27 per AmerUs
    share, pro forma);
 
        (v) the terms and conditions of the Merger Agreement, including but not
    limited to the representations, warranties and covenants thereof, the
    ability of AmVestors to consider unsolicited third party offers in the
    exercise of its fiduciary duties and to terminate the Agreement in certain
    circumstances, and the obligation of AmVestors to pay to AmerUs its expenses
    and/or a $10.8 million "breakup fee" in certain circumstances where the
    Merger is not consummated (see "CERTAIN PROVISIONS OF THE MERGER
    AGREEMENT--Conditions to the Merger", "--No Solicitation" and
    "--Termination");
 
        (vi) the opinion received by the AmVestors Board from Goldman Sachs on
    September 19, 1997 to the effect that, as of such date, the Exchange Ratio
    pursuant to the Merger Agreement was fair from a financial point of view to
    the holders of AmVestors Common Stock (see "--Opinion of the Financial
    Advisor to the AmVestors Board");
 
       (vii) the compatibility of the business and operating strategies of
    AmVestors and AmerUs offering AmVestors stockholders the opportunity to
    recognize potential increased profits and
 
                                       40
<PAGE>
    growth resulting in increased stockholder value. Except as set forth below
    with respect to the potential efficiencies and cost savings that reasonably
    could be expected to be achieved as a result of the Merger (which the senior
    management of AmVestors and AmerUs estimate will aggregate approximately
    $6-8 million in 1998 and additional amounts thereafter), the AmVestors Board
    did not consider it practicable to, nor did it attempt to, quantify all of
    the benefits that reasonably could be expected to be realized by the
    stockholders of AmVestors as a result of their continuing interest in the
    surviving company. Nonetheless, the AmVestors Board considered that there
    would be a number of such benefits, including but not limited to (A) the
    financial and managerial strength of both AmVestors and AmerUs and the
    consequent ability to enhance the on-going growth potential of the business,
    (B) the potential for growth of the AmVestors business as a result of the
    possibility of cross-marketing AmVestors products to the AmerUs policyholder
    base and (C) the potential effect of the Merger on the perception by the
    ratings agencies of the business;
 
       (viii) the potential efficiencies and synergies to be realized (including
    anticipated expense savings and operation efficiencies resulting from, among
    other things, removal of duplicative administrative and support functions
    and facilities, estimated at between $6-8 million in 1998 and additional
    amounts thereafter) by combining the operations of AmVestors and AmerUs.
 
        (ix) the historical market prices and trading information with respect
    to the shares of AmerUs Class A Common Stock and AmVestors Common Stock,
    respectively, compared to each other and to industry composites and the S&P
    500;
 
        (x) the treatment of the Merger as a "tax-free reorganization" for
    federal income tax purposes (see "--Certain U.S. Federal Income Tax
    Considerations of the Merger");
 
        (xi) the regulatory approvals required to consummate the Merger (see
    "--Regulatory Approvals") and the prospects for receiving such approvals;
 
       (xii) the interest of certain officers and directors of AmVestors and the
    fact that such officers and directors could have interests in the Merger
    that are different from other AmVestors' stockholders (see "--Certain
    Transactions; Interests of Certain Persons in the Merger");
 
       (xiii) the AmVestors' management review and due diligence of AmerUs'
    financial condition, results of operations, business and prospects and
    AmerUs' ability to consummate the transaction on a timely basis;
 
       (xiv) the potential effects arising from the fact that AmerUs' corporate
    parent, AMHC, is an Iowa mutual insurance holding company and indirectly
    owns approximately 72% of the voting securities of AmerUs, including but not
    limited to possible adverse effects on liquidity and realization of control
    premiums (see "RISK FACTORS--Holding Company Structure; Limitation on
    Dividends", "--Control by AMHC; Anti-Takeover Effects of Iowa Law and AmerUs
    Charter and Bylaws" and
    "--Relationship with AMHC; Potential Conflicts of Interest");
 
       (xv) if the AmerUs offer were rejected, the likelihood of negotiating an
    alternative transaction on as favorable a basis with another party within a
    reasonable time frame; and
 
       (xvi) that the Merger is conditioned upon approval by the holders of a
    majority of the outstanding shares of AmVestors Common Stock.
 
    Based on their analysis, the AmVestors Board determined that the Merger is
in the best interests of AmVestors' stockholders. The foregoing discussion of
the information and factors considered by the AmVestors Board is not intended to
be exhaustive, and such were considered collectively by the AmVestors Board in
connection with its review of the Merger Agreement and the transactions
contemplated thereby. In view of the variety of factors considered in connection
with its evaluation, the AmVestors Board did not find it practicable to, and did
not, quantify or otherwise rank in importance the specific factors considered in
reaching its determination. In general, however, the discussions among the
members of the AmVestors Board evidenced the view that, except as described
below, the factors enumerated above were regarded as supporting the AmVestors
Board determination to approve the
 
                                       41
<PAGE>
Merger and the Merger Agreement. The factors set forth in paragraphs (ix) and
(xi) were part of the general mix of information considered by the AmVestors
Board and while important, were not necessarily regarded as having critical
importance to its decision-making process. The factors noted in paragraphs (ii),
(v), (vi), (viii), (x), (xii), (xiv) and (xvi) were regarded as important to the
AmVestors Boards' evaluation of the transaction, with the factor noted in
paragraph (xiv) being viewed negatively as described. Finally, the factors set
forth in paragraphs (i), (iii), (iv), (vii), (xiii) and (xv) were considered
highly important to the AmVestors Board and factored heavily in its decision to
recommend approval of the Merger and the Merger Agreement. Notwithstanding the
foregoing, individual members of the AmVestors Board may have attributed
different levels of significance to different factors.
 
    The AmVestors Board has reserved the right, under certain circumstances, to
withdraw, modify or amend the foregoing recommendation in the exercise of its
fiduciary duties. See "CERTAIN PROVISIONS OF THE MERGER AGREEMENT--No
Solicitation".
 
    THE AMVESTORS BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE
MERGER AS BEING IN THE BEST INTERESTS OF STOCKHOLDERS OF AMVESTORS AND
UNANIMOUSLY RECOMMENDS THAT SUCH STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT AND THE MERGER.
 
OPINION OF THE FINANCIAL ADVISOR TO THE AMVESTORS BOARD
 
    On September 19, 1997, Goldman Sachs delivered its written opinion to the
AmVestors Board to the effect that as of the date of such opinion the Exchange
Ratio pursuant to the Merger Agreement was fair from a financial point of view
to the holders of shares of AmVestors Common Stock.
 
    THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED SEPTEMBER 19,
1997, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON
THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX III
TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. STOCKHOLDERS OF AMVESTORS ARE URGED TO, AND SHOULD, READ SUCH OPINION
IN ITS ENTIRETY.
 
    In connection with its opinion, Goldman Sachs reviewed, among other things,
(i) the Merger Agreement; (ii) an actuarial appraisal, dated May 13, 1997, of
AmVestors' insurance operations prepared by Actuarial Resources Corporation (the
"APPRAISAL"); (iii) Annual Reports to Stockholders and Annual Reports on Form
10-K of AmVestors for the five years ended December 31, 1996; (iv) certain
interim reports to stockholders and Quarterly Reports on Form 10-Q of AmVestors
and AmerUs; (v) the Registration Statement on Form S-1 of AmerUs, dated January
28, 1997; (vi) Statutory Annual Statements filed by American Investors Life
Insurance Company, Financial Benefit Life Insurance Company and AmerUs Life
Insurance Company (including the predecessor companies Central Life Assurance
Company and American Mutual Life Insurance Company) with the Insurance
Departments of the States under the laws of which they are respectively
organized for the five years ended December 31, 1996; (vii) certain interim
statutory reports filed by American Investors Life Insurance Company, Financial
Benefit Life Insurance Company and AmerUs Life Insurance Company with such
Insurance Departments; (viii) certain other communications from AmVestors and
AmerUs to their respective stockholders; (ix) certain information regarding the
reserves of AmerUs; and (x) certain internal financial analyses and forecasts
for AmVestors and AmerUs that were prepared by their respective managements.
Goldman Sachs held discussions with members of the senior management of
AmVestors and AmerUs regarding the strategic rationale for, and the potential
benefits of, the transaction contemplated by the Merger Agreement and the past
and current business operations, financial condition, and future prospects of
their respective companies. Goldman Sachs also discussed the pro forma impact of
the Merger, as well as the pending acquisition by AmerUs of Delta with the
management of AmerUs (the "PRO FORMA INFORMATION"), as well as certain other
financial analyses provided to Goldman Sachs by AmerUs regarding Delta. In
addition, Goldman Sachs reviewed the reported price and trading activity for the
AmVestors Common Stock and AmerUs Common Stock, compared certain financial and
stock market information for AmVestors and AmerUs with similar information for
certain other companies the securities of which are publicly traded, reviewed
 
                                       42
<PAGE>
the financial terms of certain recent business combinations in the life
insurance and annuities industries specifically and in other industries
generally and performed such other studies and analyses as it considered
appropriate.
 
    Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it, including the information
furnished by AmVestors and AmerUs relating to reserves and related items, and
Goldman Sachs assumed such accuracy and completeness for purposes of rendering
its opinion. In that regard, Goldman Sachs assumed, with the consent of
AmVestors, that the financial estimates of AmVestors were reasonably prepared
and reflect the best currently available judgments of AmVestors and that such
estimates will be realized in the amounts and the times contemplated thereby.
Goldman Sachs also assumed, with the consent of AmerUs, that the financial
estimates of AmerUs were reasonably prepared and reflect the best currently
available judgments of AmerUs and that such estimates will be realized in the
amounts and the times contemplated thereby. Goldman Sachs is not an actuarial
firm, and Goldman Sachs' services did not include actuarial determinations or
evaluations by Goldman Sachs or an attempt to evaluate actuarial assumptions. In
addition, Goldman Sachs has not made an independent evaluation or appraisal of
the assets and liabilities of AmVestors, AmerUs or Delta or any of their
subsidiaries and, except for the Appraisal and certain information related to
the reserves of AmVestors and AmerUs, Goldman Sachs has not been furnished with
any such evaluation or appraisal.
 
    Goldman Sachs' opinion was provided for the information and assistance of
the AmVestors Board in connection with its consideration of the transaction
contemplated by the Merger Agreement and such opinion does not constitute a
recommendation as to how any holder of shares of AmVestors Common Stock should
vote with respect to such transaction. Goldman Sachs' opinion was necessarily
based upon financial, economic, market and other conditions as they existed and
could be evaluated on the date of such opinion. Goldman Sachs expressed no
opinion as to the value of the AmerUs Class A Common Stock when issued to the
holders of shares of AmVestors Common Stock pursuant to the Merger Agreement or
to the prices at which AmerUs Class A Common Stock will trade subsequent to the
Merger.
 
    The following is a summary of certain of the financial analyses used by
Goldman Sachs in connection with providing its written opinion to the AmVestors
Board on September 19, 1997.
 
        (i)  HISTORICAL STOCK TRADING ANALYSIS.  Goldman Sachs reviewed the
    daily historical closing prices and trading volumes for shares of AmVestors
    Common Stock during the period from September 16, 1996 to September 16,
    1997. In addition, Goldman Sachs reviewed the volume of shares of AmVestors
    Common Stock traded at a range of prices between the periods from June 10,
    1994 to June 10, 1997 and from June 10, 1997 to September 16, 1997; this
    review indicated weighted
    average market prices of shares of AmVestors Common Stock of $14.01 and
    $22.01, respectively, for the periods reviewed. Goldman Sachs also reviewed
    the daily historical closing prices and trading volumes for shares of AmerUs
    Class A Common Stock for the period from January 30, 1997 to September 16,
    1997.
 
        (ii)  INDEXED STOCK PRICE HISTORIES.  Goldman Sachs reviewed the daily
    indexed historical trading prices for shares of AmVestors Common Stock
    during the period from June 10, 1997 to September 16, 1997, as compared to
    the S&P 500 and composite indexes comprised of (i) the following annuity
    companies: American Annuity, Conseco, Hartford Life, Life USA, National
    Western Life, Nationwide Financial, Presidential Life, SunAmerica and
    Western National (the "ANNUITY COMPOSITE"); and (ii) the following small-cap
    life insurance companies: American Heritage, Guarantee Life, Kansas City
    Life, Liberty Corp, Penncorp Financial and Protective Life (the "SELECTED
    SMALL-CAP LIFE COMPANIES"). Goldman Sachs also reviewed (a) the weekly
    indexed historical prices for shares of AmVestors Common Stock during the
    period from September 16, 1994 to September 12, 1997, as compared to the S&P
    500, the Annuity Composite (not including Hartford Life, Nationwide
    Financial and Western National), and the Selected Small-Cap Life Companies
    (not including Guarantee Life), (b) the daily indexed historical stock price
    for shares of AmerUs Class A Common Stock
 
                                       43
<PAGE>
    during the period from January 29, 1997 to September 16, 1997, as compared
    to the S&P 500, shares of AmVestors Common Stock, the Annuity Composite (not
    including Hartford Life and Nationwide Financial) and the Selected Small-Cap
    Life Companies, and (c) historical forward price-to-earnings ratios for
    shares of AmerUs Class A Common Stock for the period from January 29, 1997
    to September 16, 1997, as compared to shares of AmVestors Common Stock, the
    Annuity Composite (not including Hartford Life and Nationwide Financial) and
    the Selected Small-Cap Life Companies.
 
        (iii)  SELECTED COMPANIES ANALYSIS.  Goldman Sachs reviewed and compared
    certain financial information relating to AmVestors and AmerUs to
    corresponding financial information, ratios and public market multiples for
    the Selected Small-Cap Life Companies and for selected publicly traded
    large-capitalization life insurance companies and annuity companies. The
    selected large-capitalization life insurance companies were American
    General, Equitable, AFLAC, Lincoln National, UNUM, Torchmark,
    Jefferson-Pilot, Provident, ReliaStar and Unitrin (the "SELECTED LARGE-CAP
    LIFE COMPANIES"). The selected annuity companies were (i) SunAmerica,
    Conseco, Hartford Life and Nationwide Financial (the "LARGE-CAP ANNUITY
    COMPANIES"); and (ii) American Annuity, Presidential Life, ARM Financial
    Group, Life USA and National Western Life (the "SMALL-CAP ANNUITY COMPANIES"
    and, together with the Large-Cap Annuity Companies, the Small-Cap Life
    Companies and the Large-Cap Life Companies, the "SELECTED COMPANIES").
 
        The multiples of AmVestors and AmerUs were calculated using a price of
    $24.88 per share of AmVestors Common Stock and a price of $28.63 per share
    of AmerUs Class A Common Stock, the closing prices of such shares on the
    NYSE and Nasdaq, respectively, on September 17, 1997. The multiples and
    ratios for AmVestors, AmerUs and the Selected Companies were based on the
    most recent publicly available information.
 
        Goldman Sachs considered, among other multiples and ratios, (i)
    estimated price-to-earnings ratios for 1997 (the "1997 P/E RATIO") and 1998
    (the "1998 P/E RATIO"), in each case based on median Institutional Brokers
    Estimate System ("IBES") earnings estimates as of September 17, 1997 (the
    "IBES ESTIMATES"), (ii) earnings per share ("EPS") growth rates for the
    period between 1997 and 1998 based on the IBES Estimates (the "ONE YEAR EPS
    GROWTH RATE"), (iii) IBES projected five year EPS growth rates (the "FIVE
    YEAR EPS GROWTH RATE"), (iv) price as a multiple of book value adjusted to
    exclude the effect of FAS 115 (the "PRICE/BOOK RATIO"), (v) return on
    average (A) common equity ("ROACE") and (B) assets ("ROAA"), in each case
    for the twelve months ended June 30, 1997, excluding realized gains,
    accounting changes and one-time charges, (vi) the dividend yield (the
    "DIVIDEND YIELD"), and (vii) the debt to capital ratio (the "DEBT/CAPITAL
    RATIO"), giving preferred stock and capital securities 50% credit as equity.
    Goldman Sachs' analyses indicated that (a) 1997 P/E Ratios ranged from 15.4x
    to 19.3x for the Selected Large-Cap Annuity Companies with a median of
    17.7x, from 13.7x to 15.2x for the Selected Small-Cap Annuity Companies with
    a median of 14.2x, from 11.5x to 16.9x for the Selected Small-Cap Life
    Companies with a median of 14.6x, and from 14.4x to 20.7x for the Selected
    Large-Cap Life Companies with a median of 16.0x, compared with 1997 P/E
    Ratios of 15.5x for AmVestors and 14.0x for AmerUs, (b) 1998 P/E Ratios
    ranged from 13.2x to 16.7x for the Selected Large-Cap Annuity Companies with
    a median of 14.7x, from 11.1x to 14.0x for the Selected Small-Cap Annuity
    Companies with a median of 12.8x, from 9.0x to 15.2x for the Selected
    Small-Cap Life Companies with a median of 13.1x, and from 12.6x to 17.7x for
    the Selected Large-Cap Life Companies with a median of 14.4x, compared with
    1998 P/E Ratios of 13.6x for AmVestors and of 12.4x for AmerUs, (c) One Year
    EPS Growth Rates ranged from 15.2% to 22.2% for the Selected Large-Cap
    Annuity Companies with a median of 17.3%, from 8.8% to 22.8% for the
    Selected Small-Cap Annuity Companies with a median of 11.4%, from 8.7% to

    Dividend Yields ranged from .7% to 1.1% for the Selected Large-Cap Annuity
    Companies with a median of .9%, from 0.0% to 1.5% for the Selected Small-Cap

    compared with Dividend Yields of .5% for AmVestors and of 1.4% for AmerUs,
    (i) Debt/Capital Ratios ranged from 16.2% to 37.2% for the Selected

    to 36.2% for the Selected Small-Cap Life Companies with a median of 19.2%,
    and from 6.9% to 67.9% for the Selected Large-Cap Life Companies with a
    median of 25.8%, compared with Debt/Capital Ratios of 24.6% for AmVestors
    and of 18.5% for AmerUs.
 
        (iv)  STANDALONE NET PRESENT VALUE ANALYSIS.  Goldman Sachs performed a
    standalone net present value analysis per share of AmVestors Common Stock
    assuming (i) 1997 net income (excluding realized gains and losses and other
    extraordinary items) per share of $1.61 (fully diluted) based on management
    estimates, (ii) that dividends grow at the rates indicated for EPS and are
    all reinvested in AmVestors Common Stock, (iii) EPS growth rates of between
    8% and 20% after 1997, (iv) sale of a share of AmVestors Common Stock after
    five years at a hypothetical price to earnings ratio of 10.2x the following
    year's earnings, and (v) that such price per share of AmVestors Common Stock
    is discounted at rates between 8% and 16%. This analysis indicated a range
    of values per share of AmVestors Common Stock of between $11.07 and $24.06.
    The 13.3% EPS growth scenario (the five year growth rate that reflects IBES
    estimates) indicated a range of values between $13.40 and $19.15.
 
        (v)  SELECTED TRANSACTIONS ANALYSIS.  Goldman Sachs analyzed certain
    information relating to certain selected transactions in the life industry
    and annuities industries consummated or announced since January 1, 1996 (the
    "SELECTED TRANSACTIONS"). Such analysis indicated that for the Selected
    Transactions, with several data points being unavailable, aggregate equity
    consideration as a multiple of (i) last 12 months net income ranged from
    2.8x to 37.4x, with a mean of 17.8x and a median of 16.5x, (ii) tangible
    GAAP book value ranged from 1.0x to 5.2x, with a mean of 1.9x and a median
    of 1.4x, and (iii) statutory surplus ranged from 0.3x to 12.0x, with a mean
    of 3.9x and a median of 3.6x. Goldman Sachs also analyzed certain
    information relating to the following selected annuity transactions (some of
    which were among the Selected Transactions) over $100 million (the "SELECTED
    ANNUITY TRANSACTIONS"): American General Corporation/Western National Corp.
    (remaining 55% stake), Metropolitan Life Insurance Co./Security First Group
    (London Insurance Group), AmerUs Life Holdings/Delta Life, ING Group
    N.V./Equitable of Iowa Cos., SunAmerica Life Insurance/John Alden Financial
    (Annuity Operations), Conseco, Inc./American Life Holdings, Inc.
 
                                       45
<PAGE>
    (remaining 62%), General Electric Capital Corp./First Colony Corp.,
    Knightsbridge Capital Fund I/ United Companies Life Insurance, Sun America,
    Inc./Ford Life Insurance, Conseco Capital Partners II, L.P./Statesman Group,
    Inc., and General Electric Capital Corp./United Pacific Life Insurance. Such
    analysis indicated that for the Selected Annuity Transactions consummated or
    announced since April 5, 1993, with several data points being unavailable,
    aggregate equity consideration as a multiple of (a) last 12 months net
    income (excluding realized gains and losses and other extraordinary items)
    was a mean of 14.5x and a median of 15.0x, (b) tangible GAAP book value was
    a mean of 1.9x and a median of 1.6x, and (c) previous year statutory surplus
    was a mean of 2.9x and a median of 3.0x. Goldman Sachs noted that, based on
    a transaction price of $20.00, the consideration to be received by AmVestors
    stockholders pursuant to the Merger Agreement implied multiples of aggregate
    equity consideration to last 12 months net income, last 12 months net income
    (excluding realized gains and losses other than on trading securities and
    certain convertible securities), tangible GAAP book value and statutory
    surplus of 16.0x, 14.0x, 1.41x and 2.63x, respectively.
 
        (vi)  SUMMARY PRO FORMA MERGER ANALYSIS.  Goldman Sachs prepared a
    summary pro forma analysis of the Merger and the acquisition of Delta by
    AmerUs. Such analysis was based upon, among other things, a transaction
    price of $20.00, IBES estimates of EPS for AmerUs Class A Common Stock in
    1997 and 1998, and upon estimates provided by AmerUs management regarding
    synergies and other earnings enhancements expected to result from the
    Merger. Goldman Sachs' analysis indicated that the Merger and the
    acquisition of Delta would be accretive to shares of AmerUs Class A Common
    Stock on an EPS basis in 1998 and 1999, and on a book value per share basis.
 
        (vii)  CONTRIBUTION ANALYSIS.  Goldman Sachs reviewed certain historical
    operating and financial information (including, among other things,
    earnings, operating earnings, assets and shareholders' equity, and statutory
    capital) for AmVestors, AmerUs and the pro forma combined entity resulting
    from the Merger, based on publicly available information for each of
    AmVestors and AmerUs. Goldman Sachs' analysis was based on a transaction
    price of $20.00 and a price per share of AmerUs Class A Common Stock of
    $28.63. The analysis indicated that AmVestors stockholders would own 35.5%
    of the outstanding total equity of the combined entity after the Merger.
    Goldman Sachs also analyzed the relative income statement and balance sheet
    contribution of AmVestors and AmerUs to the combined entity on a pro forma
    basis for fiscal year 1996. This analysis indicated that AmVestors would
    have contributed 28.3% to combined revenues, 36.4% to combined operating
    earnings (excluding realized gains and losses and other extraordinary
    items), 34.6% to combined assets, 24.9% to combined shareholders' equity,
    and 26.2% to combined statutory capital.
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
AmVestors or AmerUs or the contemplated transaction. The analyses were prepared
solely for purposes of Goldman Sachs providing its opinion to the AmVestors
Board as to the fairness of the Exchange Ratio pursuant to the Merger Agreement
and do not purport to be appraisals or necessarily reflect the prices at which
businesses or securities actually may be sold. Analyses based upon forecasts of
future results are not necessarily indicative of actual future results, which
may be significantly more or less favorable than suggested by such analyses.
Because such analyses are inherently subject to uncertainty, being based upon
numerous factors or events beyond the control of the parties or their respective
advisors, none of AmVestors, AmerUs, Goldman Sachs or any other person assumes
responsibility if future results are materially different from those forecast.
 
    As described above, Goldman Sachs' opinion to the AmVestors Board was one of
many factors taken into consideration by the AmVestors Board in making its
determination to approve the Merger Agreement. The foregoing summary does not
purport to be a complete description of the analysis
 
                                       46
<PAGE>
performed by Goldman Sachs and is qualified by reference to the written opinion
of Goldman Sachs set forth in Annex III hereto.
 
    Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with AmVestors, having acted as its financial advisor in connection
with, and having participated in certain of the negotiations leading to, the
Merger Agreement. Goldman Sachs has also provided certain investment banking
services to AmerUs from time to time, including having acted as its financial
advisor on the formation of a mutual holding company in 1996, having acted as
lead manager of its initial public offering of AmerUs Class A Common Stock in
January 1997 and as lead manager of an issuance of the Capital Securities of
AmerUs Capital I, an affiliate of AmerUs in February 1997, and Goldman Sachs may
provide investment banking services to AmerUs in the future. AmVestors selected
Goldman Sachs as its financial advisor because it is a nationally recognized
investment banking firm that has substantial experience in transactions similar
to the Merger.
 
    Goldman Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to
time effect transactions and hold positions in the securities or options on
securities of AmVestors and/or AmerUs for its own account and for the account of
customers.
 
    Pursuant to a letter agreement dated April 17, 1997 (the "GOLDMAN SACHS
ENGAGEMENT LETTER"), AmVestors engaged Goldman Sachs to act as its financial
advisor in connection with the Merger. Pursuant to the terms of the Goldman
Sachs Engagement Letter, AmVestors has agreed to pay Goldman Sachs upon
consummation of the Merger a transaction fee of $3.5 million plus 4% of the
amount by which the aggregate consideration paid in the Merger exceeds $362.5
million. AmVestors has agreed to reimburse Goldman Sachs for its reasonable
out-of-pocket expenses, including attorney's fees, and to indemnify Goldman
Sachs against certain liabilities, including certain liabilities under the
federal securities laws.
 
REGULATORY APPROVALS
 
    Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), the Merger may not be consummated until notifications
have been given and certain information has been furnished to the FTC and the
Antitrust Division of the Department of Justice (the "ANTITRUST DIVISION") and
specified waiting period requirements have been satisfied. AmVestors and AmerUs
filed notification and report forms under the HSR Act with the FTC and the
Antitrust Division on November 10, 1997. The latest required waiting periods for
such filings under the HSR Act are due to expire on December 10, 1997 (assuming
no request for additional information is received). However, at any time before
or after the Effective Time of the Merger, and notwithstanding that the HSR Act
waiting period has expired, the FTC, the Antitrust Division or any state could
take such action under the antitrust laws as it deems necessary or desirable in
the public interest. Such action could include seeking to enjoin the
consummation of the Merger or seeking divestiture of AmVestors or businesses of
AmerUs or AmVestors acquired as a result of the Merger.
 
    Under Kansas insurance laws and related regulations, the acquisition of
control of a domestic insurer must receive prior approval by the state's
insurance department. Kansas law provides that a transaction will be approved if
the insurance department finds that the transaction would, among other things,
not violate the law or be contrary to the interest of the insureds of any
participating domestic insurer. Applications for approval of the Merger and all
related transactions were submitted to the Kansas Insurance Department on
October 28, 1997. At the suggestion of the Florida Insurance Commissioner,
AmVestors has filed a document to cause the redomestication of FBL from Florida
to Kansas. Filings of pre-acquisition notification have been made in certain
states where insurance holding systems acts contain anti-competition provisions
pertaining to the lines of business in which AmVestors or any of its
 
                                       47
<PAGE>
insurance subsidiaries compete. In addition, certain states' insurance licensing
laws require relicensing of AmVestors insurance subsidiaries after consummation
of the Merger.
 
    Under Iowa insurance laws and related regulations, the offering of stock by
AmerUs must receive prior approval by the Iowa Commissioner of Insurance. An
application for approval of the stock issuance will be submitted by AmerUs to
the Iowa Commissioner of Insurance.
 
    The Merger Agreement generally provides for a ninety day extension beyond
the Outside Date (as defined below) if the Merger shall not have occurred as a
result of a failure to receive governmental approvals.
 
FORM OF THE MERGER
 
    If the approval of the AmVestors stockholders and the approval of the AmerUs
shareholders are obtained and all other conditions to the Merger are satisfied
or waived, Merger Sub will be merged with and into AmVestors, with AmVestors
being the surviving corporation after the Merger and a wholly owned subsidiary
of AmerUs. The date on which the closing of the Merger shall occur is referred
to herein as the "CLOSING DATE."
 
MERGER CONSIDERATION
 
    The Merger Agreement provides that, as of the Effective Time, each
outstanding share of AmVestors Common Stock (other than any held in treasury by
AmVestors) shall be converted into the right to receive (x) if the Average
AmerUs Share Price (as defined below) is greater than or equal to $27.00 but
less than or equal to $29.75, the number of shares of AmerUs Class A Common
Stock determined by dividing $20.00 by the Average AmerUs Share Price and
rounding the result to the nearest one ten-thousandth of a share; (y) if the
Average AmerUs Share Price is less than $27.00, 0.7407 shares of AmerUs Class A
Common Stock (subject to AmVestors' termination right described below); and (z)
if the Average AmerUs Share Price is greater than $29.75, 0.6724 shares of
AmerUs Class A Common Stock (as applicable, the "MERGER CONSIDERATION" or
"EXCHANGE RATIO"). The "AVERAGE AMERUS SHARE PRICE" means the average of the
last reported sales prices per share of AmerUs Class A Common Stock as quoted by
Nasdaq for the 20 consecutive trading days (the "VALUATION PERIOD") ending on
the trading day (the "PRICE MEASURING DATE") which is ten trading days prior to
the Closing Date.
 
    In the event that the Average AmerUs Share Price on the Price Measuring Date
is less than $27.00, AmVestors shall have the option to deliver a written notice
to AmerUs on the trading day following the Price Measuring Date providing for
the termination of the Merger Agreement subject to the next sentence (the
"TERMINATION NOTICE"). If AmVestors properly delivers a Termination Notice, the
Merger Agreement shall terminate at the close of business on the fifth trading
day following the Price Measuring Date unless prior to such time AmerUs shall
have delivered a written notice to AmVestors whereby AmerUs agrees to adjust the
consideration into which each share of AmVestors Common Stock is convertible
from the Merger Consideration as determined above to the adjusted Merger
Consideration ("ADJUSTED MERGER CONSIDERATION") determined by dividing $20.00 by
the Average AmerUs Share Price as of the Price Measuring Date and rounding the
result to the nearest one ten-thousandth of a share (termination of the Merger
Agreement under such circumstances is referred to herein as the "TERMINATION FOR
PRICE"). If AmVestors did not deliver a Termination Notice under the
circumstances described in this paragraph, the Merger Consideration would be
valued (based upon the Average AmerUs Trading Price) at less than $20.00. SINCE
AMVESTORS' DECISION WHETHER TO EXERCISE ITS RIGHT TO DELIVER A TERMINATION
NOTICE IS DEPENDENT, TO SOME EXTENT, ON CIRCUMSTANCES EXISTING AT THE TIME OF
SUCH DECISION, THERE CAN BE NO ASSURANCE AT THIS TIME AS TO WHETHER OR NOT
AMVESTORS WOULD ELECT TO EXERCISE SUCH RIGHT.
 
    The Merger Consideration generally is intended to provide shares of AmerUs
Class A Common Stock valued at not less than $20.00, based upon the Average
AmerUs Share Price, provided that the Merger Consideration would be valued at
less than $20.00 per share if the Average AmerUs Trading Price is less than
$27.00 and the AmVestors Board does not terminate the Merger Agreement as
 
                                       48
<PAGE>
described above. Therefore, a higher Average AmerUs Share Price up to $29.75
would result in fewer shares of AmerUs Class A Common Stock constituting the
Merger Consideration, and a lower Average AmerUs Share Price down to $27.00
would result in more shares of AmerUs Class A Common Stock constituting the
Merger Consideration. If the Average AmerUs Share Price were equal to $31 11/16
per share, the last sales price of AmerUs Class A Common Stock as reported on
Nasdaq, on November 11, 1997, the Merger Consideration would be equal to 0.6724
of one share of AmerUs Class A Common Stock. The aggregate number of shares of
AmerUs Class A Common Stock issued in connection with the Stock Issuance
immediately following the Merger is expected to be between approximately 11.6
million and 12.8 million shares (based upon an Average AmerUs Share Price of $27
and $29.75, respectively, and in each case assuming that all options and
warrants are rolled over into options to acquire shares of AmerUs Class A Common
Stock). Unless AmerUs agrees to pay the Adjusted Merger Consideration, the
aggregate number of shares of AmerUs Class A Common Stock issued and issuable
should not be more than 14.7 million shares (which would occur if the Average
AmerUs Share Price is $27.00 or less assuming conversion of the AmVestors
Convertible Debentures and exercise of all outstanding options and warrants to
purchase AmVestors Common Stock). If the Stock Issuance is approved, the AmerUs
Board would have the authority to agree to pay the Adjusted Merger
Consideration. If such authority were exercised, the total number of shares of
AmerUs Class A Common Stock issued and issuable in the Merger could exceed 14.7
million, potentially by a significant amount.
 
    AmerUs and AmVestors anticipate that the Closing Date will occur as promptly
as practicable following satisfaction or waiver of each of the conditions to the
Merger, including approval of the Merger Agreement by the holders of the
requisite number of shares of AmVestors Common Stock and approval of the Stock
Issuance by the requisite number of shares of AmerUs Common Stock. If the
Special Meetings occur prior to the end of the Valuation Period, the number of
shares of AmerUs Class A Common Stock constituting the Merger Consideration will
not be known at the time the vote on the approval of the Merger Agreement is
held. The Merger Agreement provides that the Valuation Period will end ten
trading days prior to the Closing Date, and therefore the number of shares of
AmerUs Class A Common Stock constituting the Merger Consideration will be fixed
at that time. The market price of AmerUs Class A Common Stock and hence the
value of the Merger Consideration are expected to fluctuate with the performance
of AmerUs and general market conditions. The last sales price of AmerUs Class A
Common Stock on the Closing Date may be higher or lower than the Average AmerUs
Share Price, and as a result, the value of the Merger Consideration at the
Closing Date may be more or less than $20.00. See "RISK FACTORS."
 
    If between the date of the Merger Agreement and the Effective Time the
outstanding shares of AmerUs Class A Common Stock shall have been changed into a
different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares, the Merger Consideration shall be correspondingly adjusted
to the extent appropriate to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares.
 
EFFECTIVE TIME
 
    The Merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of the State of Kansas. Such filing will be made as
promptly as practicable after satisfaction or waiver of the conditions to the
Merger.
 
EXCHANGE PROCEDURES
 
    From and after the Effective Time, AmerUs shall make available to
ChaseMellon Shareholder Services LLC (the "EXCHANGE AGENT"), for the benefit of
the holders of shares of AmVestors Common Stock, exchange certificates
evidencing such number of shares of AmerUs Class A Common Stock issuable to
holders of AmVestors Common Stock in the Merger and, upon request of the
Exchange Agent, cash in the amount required to be exchanged for fractional
shares of AmVestors Common Stock in the Merger.
 
                                       49
<PAGE>
    As promptly as practicable after the Effective Time, AmerUs shall cause the
Exchange Agent to mail to each holder of a certificate or certificates which
immediately prior to the Effective Time represented outstanding shares of
AmVestors Common Stock (the "CERTIFICATES") (i) a letter of transmittal (which
shall be in customary form and shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon proper
delivery of the Certificates to the Exchange Agent) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for certificates
evidencing shares of AmerUs Class A Common Stock.
 
    Upon surrender to the Exchange Agent of a Certificate for cancellation,
together with such letter of transmittal, duly executed and completed in
accordance with the instructions thereto, and such other documents as may be
reasonably required pursuant to such instructions, the holder of such
certificate shall be entitled to receive in exchange therefor (i) a certificate
representing that number of whole shares of AmerUs Class A Common Stock, if any,
which such holder has the right to receive and a check in the amount equal to
the cash, if any, which such holder has the right to receive in lieu of any
fractional shares of AmerUs Class A Common Stock and any dividends or other
distributions to which such holder is entitled, and the Certificate so
surrendered shall forthwith be canceled.
 
    No dividends or other distributions declared or made after the Effective
Time with respect to AmerUs Class A Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of AmerUs Class A Common Stock represented thereby, and no
cash payment in lieu of any fractional shares shall be paid to any such holder,
until the holder of such Certificate shall surrender such Certificate. Subject
to the effect of escheat, tax or other applicable laws, following surrender of
any such Certificate, there shall be paid to the holder of the certificates
representing whole shares of AmerUs Class A Common Stock issued in exchange
therefor, without interest, (i) promptly, the amount of any cash payable with
respect to a fractional share of AmerUs Class A Common Stock to which such
holder is entitled and the amount of dividends or other distributions with a
record date after the Effective Time and theretofore paid with respect to such
whole shares of AmerUs Class A Common Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions, with a record date after
the Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of AmerUs Class A Common
Stock.
 
    At the Effective Time, the stock transfer books of AmVestors shall be closed
and there shall be no further registration of transfers of shares of AmVestors
Common Stock thereafter on the records of AmVestors. From and after the
Effective Time, the holders of Certificates shall cease to have any rights with
respect to the shares of AmVestors Common Stock represented by such
Certificates, except as otherwise provided herein or by law. On or after the
Effective Time, any Certificates presented to the Exchange Agent or AmerUs for
any reason shall be converted into shares of AmerUs Class A Common Stock, and
any cash in lieu of fractional shares of AmerUs Class A Common Stock and any
dividends or other distributions to which the holders thereof are entitled shall
be paid.
 
NASDAQ LISTING
 
    AmerUs has agreed to file an application to list the shares of AmerUs Class
A Common Stock to be issued in connection with the Merger on Nasdaq, subject to
approval of the Stock Issuance by the AmerUs shareholders and the Merger
Agreement by the AmVestors stockholders and official notice of issuance. The
shares of AmerUs Class A Common Stock are traded on Nasdaq under the symbol
"AMRS."
 
CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE MERGER
 
    The following summary, based upon current law and subject to the
qualifications set forth below and contained therein, sets forth the opinion of
Skadden, Arps, Slate, Meagher & Flom LLP, counsel to AmerUs, and Bryan Cave LLP,
counsel to AmVestors, as to the material U.S. federal income tax consequences of
the Merger to holders of AmVestors Common Stock that hold their shares of
AmVestors Common Stock as capital assets. Such opinion is not binding on the
IRS. This summary is based upon
 
                                       50
<PAGE>
the Internal Revenue Code of 1986, as amended (the "CODE"), applicable Treasury
regulations thereunder and administrative rulings and judicial authority as of
the date hereof, all of which are subject to change at any time, possibly with
retroactive effect. Any such change could affect the continuing validity of this
summary. This summary does not purport to discuss all aspects of U.S. federal
income taxation that may be relevant to a particular holder of AmVestors Common
Stock in light of such holder's specific circumstances or to certain types of
holders subject to special treatment under U.S. federal income tax laws (for
example, foreign persons, dealers in securities, banks and other financial
institutions, tax-exempt organizations and holders who acquired AmVestors Common
Stock pursuant to the exercise of options or otherwise as compensation or
through a tax-qualified retirement plan). Tax considerations under state, local
and foreign tax laws are not addressed herein. EACH AMVESTORS STOCKHOLDER IS
URGED TO CONSULT HIS OR HER TAX ADVISOR AS TO THE SPECIFIC TAX CONSIDERATIONS OF
THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND
FOREIGN TAX LAWS IN HIS OR HER PARTICULAR CIRCUMSTANCES.
 
    No ruling has been (or will be) sought from the Internal Revenue Service as
to the U.S. federal income tax consequences of the Merger. It is a condition to
the consummation of the Merger that AmerUs receive an opinion from its counsel,
Skadden, Arps, Slate, Meagher & Flom LLP, and that AmVestors receive an opinion
from its counsel, Bryan Cave LLP, substantially to the effect that, based upon
certain facts, representations and assumptions, the Merger will be treated for
U.S. federal income tax purposes as a reorganization within the meaning of
Section 368(a) of the Code; neither AmerUs nor AmVestors will waive such
condition to the consummation of the Merger. In rendering such opinions, counsel
may require and rely upon (and may incorporate by reference), representations
and covenants, including those contained in certificates of officers of AmerUs,
AmVestors, Merger Sub and others. The specific provisions of each such
representation and covenant shall be in form and substance reasonably
satisfactory to such counsel.
 
    Subject to the qualifications set forth herein and assuming that the Merger
is treated for U.S. federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code, it is the opinion of Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to AmerUS, and Bryan Cave LLP, counsel to
AmVestors, that the Merger will result in the following U.S. federal income tax
consequences:
 
1.  No gain or loss will be recognized by holders of AmVestors Common Stock who
    exchange their AmVestors Common Stock for AmerUs Class A Common Stock
    pursuant to the Merger, except with respect to any cash received by such
    AmVestors stockholders in lieu of the receipt of fractional shares of AmerUs
    Class A Common Stock.
 
2.  A holder of AmVestors Common Stock who receives cash in lieu of a fractional
    share of AmerUs Class A Common Stock in the Merger generally will be treated
    as if the fractional share had been distributed to such holder as part of
    the Merger and then redeemed by AmerUs in exchange for the cash. This cash
    payment will be treated as having been received in exchange for the redeemed
    fractional share under Section 302 of the Code. The receipt of such cash
    payment generally should result in capital gain or loss equal to the
    difference between the amount of cash received and the holder's basis in the
    fractional share of AmerUs Class A Common Stock deemed to be redeemed.
 
3.  Each holder of AmVestors Common Stock who exchanges his or her AmVestors
    Common Stock for AmerUs Class A Common Stock pursuant to the Merger will
    have an aggregate tax basis in the AmerUs Class A Common Stock received in
    the Merger equal to his or her aggregate tax basis in the AmVestors Common
    Stock exchanged therefor, decreased by the amount of any tax basis allocable
    to any fractional share interest for which cash is received.
 
4.  Provided that the shares of AmVestors Common Stock are held as a capital
    asset at the Effective Time, the holding period of AmerUs Class A Common
    Stock received in the Merger in exchange therefor will include the holding
    period of such AmVestors Common Stock.
 
5.  AmerUs, AmVestors and Merger Sub will not recognize any gain or loss as a
    result of the Merger.
 
    BACKUP WITHHOLDING.  To prevent "backup withholding" of U.S. federal income
tax on any payments of cash to a holder of AmVestors Common Stock in the Merger,
a holder of AmVestors Common
 
                                       51
<PAGE>
Stock must, unless an exception applies under the applicable law and
regulations, provide the payor of such cash with such holder's correct taxpayer
identification number ("TIN") on a Substitute Form W-9 and certify under
penalties of perjury that such number is correct and that such holder is not
subject to backup withholding. A Substitute Form W-9 will be provided to each
holder of AmVestors Common Stock in the letter of transmittal to be mailed to
each holder after the Effective Time. If the correct TIN and certifications are
not provided, a $50 penalty may be imposed on a holder of AmVestors Common Stock
by the Internal Revenue Service, and any cash to be received by such holder may
be subject to backup withholding at a rate of 31%.
 
    THE U.S. FEDERAL INCOME TAX CONSIDERATIONS SET FORTH ABOVE ARE BASED UPON
PRESENT LAW, ARE FOR GENERAL INFORMATION ONLY AND DO NOT PURPORT TO BE A
COMPLETE ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS WHICH MAY APPLY TO A
HOLDER OF AMVESTORS COMMON STOCK. THE TAX EFFECTS AS APPLICABLE TO A PARTICULAR
HOLDER OF AMVESTORS COMMON STOCK MAY BE DIFFERENT FROM THE TAX EFFECTS AS
APPLICABLE TO OTHER HOLDERS OF AMVESTORS COMMON STOCK, INCLUDING THE APPLICATION
AND EFFECT OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAW, AND THUS, HOLDERS OF
AMVESTORS COMMON STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS.
 
TREATMENT OF AMVESTORS STOCK OPTIONS
 
    Prior to the Closing, the AmVestors Board (or, if appropriate, any committee
administering AmVestors' 1989 Non-Qualified Stock Option Plan (the "NQSO PLAN")
or 1996 Incentive Stock Option Plan (the "ISO PLAN," and together with the NQSO
Plan, the "AMVESTORS OPTION PLANS") shall adopt such resolutions or take such
other actions as may be required to adjust the terms of all outstanding
AmVestors options issued pursuant to the AmVestors Option Plans and related
agreements (the "AMVESTORS OPTIONS"), to provide that at the Effective Time,
each AmVestors Option outstanding (whether or not vested and exercisable)
immediately prior to the Effective Time shall at the Effective Time cease to
represent a right to acquire shares of AmVestors Common Stock and shall be
converted automatically into an option (a "CONTINUING OPTION") to acquire AmerUs
Class A Common Stock in an amount and at an exercise price determined as
provided in the immediately following sentence (and on substantially the same
terms and conditions as were applicable under such AmVestors Option Plan and the
agreements evidencing grants thereunder). At the Effective Time, if the holder
of an AmVestors Option which is then outstanding and unexercised has not timely
elected (with respect to AmVestors Options granted under the NQSO Plan) or has
not timely requested (with respect to AmVestors Options granted under the ISO
Plan; or if so requested, if such request has been denied by AmVestors) to
receive cash for such AmVestors Option as described below, then such AmVestors
Option shall, in accordance with the provisions of the NQSO Plan or the ISO
Plan, whichever is applicable, become a Continuing Option to acquire (x) the
number of shares of AmerUs Class A Common Stock equal to the product of (i) the
number of shares of AmVestors Common Stock subject to such AmVestors Option
immediately prior to the Effective Time multiplied by (ii) the Merger
Consideration (a partial share shall be rounded down to the next lower whole
share), with (y) an exercise price equal to the quotient of (i) the original
exercise price per share (the "ORIGINAL EXERCISE PRICE") of AmVestors Common
Stock subject to such AmVestors Option in effect immediately prior to the
Effective Time divided by (ii) the Merger Consideration and rounding the
exercise price thus determined to the nearest whole cent (a half cent shall be
rounded to the next higher whole cent). In the case of AmVestors Options
intended to be incentive stock options, the exercise price, number of shares of
AmerUs Class A Common Stock subject to such Continuing Option and terms and
conditions or exercise of such Continuing Option shall be determined in order to
comply with the requirements of Section 424(a) of the Code.
 
    Prior to the Closing, AmVestors shall deliver to the holders of AmVestors
Options (whether or not vested and exercisable) a notice offering to (i) holders
of AmVestors Options issued pursuant to the NQSO Plan the right to elect, and
(ii) holders of AmVestors Options issued pursuant to the ISO Plan the right to
request, to receive in consideration for the cancellation of all (but not less
than all) of such holder's AmVestors Options, an amount in cash equal to the
product of (x) the excess of (i) the Option
 
                                       52
<PAGE>
Cash Price (as defined below), over (ii) the Original Exercise Price of such
AmVestors Option, multiplied by (y) the number of shares subject to such
AmVestors Option. AmVestors intends to grant all requests from holders of
AmVestors Options issued pursuant to the ISO Plan to receive cash. The "OPTION
CASH PRICE" is the product of (A) the last reported sales price per share of
AmerUs Class A Common Stock as quoted by Nasdaq on the Closing Date multiplied
by (B) the Merger Consideration. Alternatively, with the consent of AmerUs prior
to the Closing, holders of AmVestors Options may request to receive in
consideration for the cancellation of such holder's AmVestors Options, a number
of shares of AmerUs Class A Common Stock (rounded down to the nearest whole
share) equal to the amount of cash which otherwise would be payable upon
termination of such AmVestors Options as described in the first sentence of this
paragraph, divided by the last sales price of AmerUs Class A Common Stock as
reported on Nasdaq as of the Effective Time.
 
    To make the election for cash consideration, any eligible AmVestors Option
holder must deposit with the Exchange Agent at least ten trading days prior to
the Closing a properly completed notice in accordance with the Merger Agreement.
Following the Effective Time, AmVestors shall deliver to each such holder the
cash amount so elected. No interest shall be paid on such amount. If the Merger
Agreement is terminated before the Effective Time, the option agreements will be
returned to each such holder.
 
RESALES OF AMERUS CLASS A COMMON STOCK
 
    All shares of AmerUs Class A Common Stock to be issued in connection with
the Merger, as well as upon exercise of certain warrants (the "PUBLIC WARRANTS")
which were registered under the Securities Act by AmVestors, are being
registered under the Securities Act. Such shares will be freely transferable,
except that shares received by any person who may be deemed to be an affiliate
within the meaning of Rule 145 of the rules and regulations promulgated under
the Securities Act (each such person being an "AFFILIATE") of AmVestors may not
be resold except in transactions permitted by such Rule 145 or as otherwise
permitted under the Securities Act.
 
    AmVestors has agreed to deliver to AmerUs a list of names and addresses of
those persons who were, in AmVestors' reasonable judgment, Affiliates of
AmVestors. AmVestors has also agreed to use its reasonable efforts to cause to
be delivered to AmerUs, on or prior to the Closing Date, a letter substantially
in the form agreed to by AmVestors and AmerUs, executed by each of the
Affiliates of AmVestors identified in the foregoing list and by any person who
shall have become an Affiliate of AmVestors subsequent to the delivery of such
list.
 
    Prior to the Closing Date, AmVestors shall use its reasonable efforts to
deliver to AmerUs a letter identifying all persons who are, at the time the
Merger Agreement is submitted for approval to the stockholders of AmVestors,
Affiliates of AmVestors (including all directors of AmVestors).
 
ACCOUNTING TREATMENT
 
    The Merger will be accounted for by AmerUs under the "purchase" method of
accounting in accordance with generally accepted accounting principles.
Therefore, the aggregate consideration paid by AmerUs in connection with the
Merger will be allocated to AmVestors' assets and liabilities based on their
fair market values with any excess being recorded as goodwill. The assets and
liabilities and results of operations of AmVestors will be consolidated into the
assets and liabilities and results of operations of AmerUs subsequent to the
Effective Time.
 
NO DISSENTERS' RIGHTS
 
    Pursuant to Section 17-6712(k) of the Kansas General Corporation Code
("KGCC"), holders of the AmVestors Common Stock are not entitled to dissenter
appraisal rights in connection with the Merger since (i) the AmVestors Common
Stock is registered and traded on the NYSE (and the AmVestors' Articles of
Incorporation do not otherwise provide for such appraisal rights in connection
with the Merger) and (ii) the shares of AmerUs Class A Common Stock to be issued
to holders of AmVestors Common Stock in the Merger are registered on Nasdaq.
 
                                       53
<PAGE>
    The IBCA (as defined below) does not provide for dissenter appraisal rights
to holders of the AmerUs Class A Common Stock in connection with the Stock
Issuance.
 
CERTAIN TRANSACTIONS; INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In considering the recommendation of the AmVestors Board with respect to the
Merger, AmVestors stockholders should be aware that certain directors and
officers of AmVestors have interests in the Merger different from the interests
of other AmVestors stockholders.
 
    CHANGE IN CONTROL ARRANGEMENT.  Mr. Ralph W. Laster, Jr., Chairman of the
Board and Chief Executive Officer of AmVestors, and Mr. Mark V. Heitz, President
and General Counsel of AmVestors, are parties to an Incentive Agreement and a
special Incentive Bonus Arrangement which are intended to provide additional
compensation based upon the performance of AmVestors Common Stock ("SARS"). Mr.
Laster and Mr. Heitz hold such SARs with respect to 475,000 shares and 345,500
shares, respectively, at a weighted average strike price of $15.487 per share
and $15.510 per share, respectively. Pursuant to such arrangements, generally,
in the event that AmVestors enters into an agreement providing for a transaction
in which AmVestors Common Stock is converted into the right to receive any
stock, cash or other property, the holder of a SAR is entitled to receive a
payment in cash upon consummation of such transaction equal to the product of
the number of shares referenced by such SAR multiplied by the difference between
the aggregate fair market value of the stock, cash or other property receivable
in exchange for one share of AmVestors Common Stock (generally as determined in
good faith by AmVestors Board as of the date of the exchange) minus the strike
price. Upon consummation of the Merger, Messrs. Laster and Heitz will receive
approximately $2,150,275 and $1,555,334, respectively, pursuant to such terms of
the SARs (assuming an exchange ratio which values each share of AmVestors Common
Stock at $20).
 
    EMPLOYMENT AGREEMENTS.  Messrs. Laster and Heitz are parties to separate
employment agreements with AmVestors that entitle them, upon a change of control
of AmVestors, to terminate their employment and be paid, in the case of Mr.
Laster, three years of salary (which is $450,000 per year) and in the case of
Mr. Heitz, two years of salary (which is $337,500 per year) commencing on the
date of termination in consideration for their non-competition obligations under
such agreements. Since Mr. Heitz has agreed to enter into an employment
agreement with the Surviving Corporation on substantially similar terms upon the
Effective Time, Mr. Heitz has agreed to waive his right to any change of control
or severance payment under his existing employment agreement with AmVestors.
Executive vice presidents of AmVestors are parties to employment agreements with
AmVestors that entitle them to payment of twelve months of salary upon any
termination by AmVestors of their employment that is not for cause (which the
AmVestors Board has determined would include any termination resulting from a
change of control). Frank T. Crohn, a director of AmVestors and Chairman of the
Boards of FBL, AIMCOR and Annuity Warehouse, Inc. f/k/a The Insurance Mart, and
Donna J. Rubertone, President of FBL, are parties to employment agreements with
AmVestors that will entitle them to payment of the remainder of the cash
compensation under such contract if, following a merger involving AmVestors, Mr.
Crohn or Ms. Rubertone, as the case may be, is not designated to the positions
and given the duties described in such agreement. Mr. Crohn's and Ms.
Rubertone's contracts terminate by their terms on April 7, 1998 and April 7,
1999, respectively.
 
    BONUS PLAN.  Under the AmVestors Bonus Compensation Plan, certain employees,
including all of the executive officers, of AmVestors are entitled to payment of
a "cash bonus" (payment made in a lump sum) and a "salary bonus" (payment made
over time in accordance with normal pay practices), based upon the fulfillment
by AmVestors of certain performance objectives. Pursuant to the Bonus
Compensation Plan, if any such employee's employment is terminated as a result
of a change of control, such employee is entitled to a lump sum payment of the
full amount of any cash bonus and salary bonus for which such employee is
eligible (whether or not performance objectives were obtained) for the remainder
of the calendar year in which the termination occurred. For 1997 compensation,
the maximum bonus potential for executive officers of AmVestors under the Bonus
Compensation Plan ranges from 35% to 75% of base salary.
 
                                       54
<PAGE>
    SEVERANCE COMPENSATION PLAN.  Pursuant to a severance compensation plan
established by the AmVestors Board (the "SEVERANCE COMPENSATION PLAN"),
employees and officers of AmVestors may become entitled to certain severance
compensation in the event of termination of their employment without cause
(whether by AmVestors or by any successor to the business of AmVestors,
including succession by merger), which occurs within one year after such
transaction. The standard severance payment under the Severance Compensation
Plan is two weeks of salary ("BASE SEVERANCE") plus an additional two weeks of
salary for each full year of service, with officers of AmVestors being entitled
to receive the greater of (i) additional weeks of Base Severance (up to 18
weeks) based upon the seniority of the officer position held or (ii) the amount
of severance provided under his or her employment agreement with AmVestors (if
any). In addition, Mr. Laster has discretionary authority to offer to any
employee of AmVestors, in addition to other severance compensation, an
additional severance payment (a "DISCRETIONARY SEVERANCE PAYMENT"). Executive
vice presidents have been granted Discretionary Severance Payments equal to one
year's salary to be paid in the event their employment is terminated as a result
of the Merger. From the date of the Merger Agreement, Mr. Laster may not make
any additional Discretionary Severance Payments to any employee in excess of
$30,000 or amounting to more than $300,000 in aggregate.
 
    LIABILITY INSURANCE COVERAGE.  Pursuant to the Merger Agreement, AmerUs and
Merger Sub have agreed to maintain directors' and officers' liability insurance
for the current and former directors and officers of AmVestors for a period of
six years after the Effective Time.
 
    BOARD SEAT; EMPLOYMENT AFTER CLOSING.  AmerUs has requested, and Mr. Laster
has agreed, that, after the Effective Time, Mr. Laster will serve as a director
of AmerUs. It is expected that Mr. Laster will be appointed to fill an existing
vacancy on the AmerUs Board and that he will be nominated at the next annual
meeting for a two-year term as director expiring in 2000. As a director of
AmerUs, Mr. Laster will be entitled to receive the compensation payable to
AmerUs directors as described under "MANAGEMENT BEFORE AND AFTER THE MERGER --
Compensation of Directors." Assuming Mr. Heitz does not elect to receive cash
for outstanding options, upon consummation of the Merger Mr. Heitz would become
the beneficial owner of up to 204,786 shares of AmerUs Class A Common Stock
including options to acquire 148,140 shares of AmerUs Class A Common Stock, some
or all of which may be sold from time to time pursuant to the Registration
Statement of which this Joint Proxy Statement/Prospectus forms a part. Mr. Heitz
and AmerUs have agreed to enter into an employment agreement whereby, upon the
Effective Time, Mr. Heitz would become the President and Chief Executive Officer
of AmVestors (the Surviving Corporation) on substantially the same terms as Mr.
Heitz's current employment agreement with AmVestors. Assuming Mr. Laster does
not elect to receive cash for outstanding options, upon consummation of the
Merger Mr. Laster would become the beneficial owner of up to 255,037 shares of
AmerUs Class A Common Stock including options to acquire 185,175 shares of
AmerUs Class A Common Stock, some or all of which may be sold from time to time
pursuant to the Registration Statement of which this Joint Proxy
Statement/Prospectus forms a part. Except for the arrangements specifically set
forth in this Joint Proxy Statement/Prospectus and the Merger Agreement, AmerUs
has made no commitments with respect to the retention of AmVestors employees
after the Merger.
 
    AFFILIATION WITH SPECIAL ADVISOR.  Mr. James V. O'Donnell, a director of
AmVestors, is President of Bush-O'Donnell, AmVestors' special advisor in
connection with the Merger. Pursuant to the terms of an engagement letter dated
April 22, 1997 between AmVestors and Bush-O'Donnell, AmVestors has agreed to pay
Bush-O'Donnell a fee for its services of $350,000 plus .4% of the amount by
which the aggregate Merger Consideration exceeds $362.5 million.
 
    STOCK OPTIONS.  On October 20, 1997, R. Rex Lee, M.D., a director of
AmVestors, exercised options resulting in the net acquisition of 63,675 shares
of AmVestors Common Stock and subsequently sold such shares to AmerUs Group for
$20 per share plus payment, upon consummation of the Merger, of an amount per
share equal to the amount (the "ADDITIONAL AMOUNT") by which the lesser of (i)
the Merger Consideration or (ii) $20.625, exceeds $20. In the event the Merger
Agreement is terminated pursuant to Article IX thereof, AmerUs will pay Dr. Lee
a per share amount equal to the closing price of AmVestors Common Stock on the
fifth trading day following the first public announcement of such
 
                                       55
<PAGE>
termination less $20, up to the Additional Amount. As of October 22, 1997, Dr.
Lee retained beneficial ownership of 5,000 shares of AmVestors Common Stock.
 
    In connection with the exercise of options by Mark V. Heitz in October, 1997
AmVestors loaned Mr. Heitz $250,000 for payment of taxes realized by Mr. Heitz
on such exercise. Such loan bears interest at the prime rate and is payable in
full on December 31, 1997.
 
    Each officer of AmVestors who holds AmVestor Options under the ISO Plan will
become fully vested in such options and each director or officer of AmVestors
who holds AmVestors Options will be entitled to elect to convert such AmVestors
Options into Continuing Options of AmerUs or receive (or for options under the
ISO Plan, request) cash payment for the value thereof (or, with respect to
certain AmVestors Options, at the holder's election and with AmerUs' consent,
shares of AmerUs Class A Common Stock equivalent to such value). See
"--Treatment of AmVestors Stock Options." The following table sets forth
information with respect to the cash amounts payable to executive officers of
AmVestors upon consummation of the Merger for AmVestors Options held by them,
assuming (i) that such officers elect or request to receive cash for such
options and (ii) an exchange ratio which values each share of AmVestors Common
Stock at $20 per share.

or other reserve for financial reporting purposes or for
 
                                       57

other accounting purposes (including without limitation, any practice, policy,
assumption, or method relating to or affecting the determination of insurance or
annuities in force, premium or investment income, reserve liabilities, or
operating ratios with respect to expenses, losses, or lapses). AmVestors also
agreed to (i) prepare properly and file duly and validly all reports and all tax
returns required to be filed with any governmental or regulatory authorities
with respect to its business, operations, or affairs and (ii) pay in full and
when due all taxes indicated by such tax returns or otherwise levied or assessed
upon it or any of its assets and properties, and withhold or collect and pay to
the proper taxing authorities or hold in separate bank accounts for such payment
all taxes that it is required to so withhold or collect and pay, unless
reasonable reserves therefor have been established and reflected in its books
and records. AmVestors agreed not to make any tax election with respect to such
tax returns without the consent of AmerUs, which consent shall not be
unreasonably withheld. AmVestors shall not and shall not permit any Acquired
Company to settle any material audit, make or change any material tax election
or file any amended tax return (except as previously disclosed to AmerUs). At
least 10 days prior to filing any income tax return or other material tax return
relating to AmVestors or any Acquired Company, AmVestors shall deliver a copy of
such tax return to AmerUs for AmerUs' review and comment. AmVestors agreed to
refrain from making, filing, or entering into (whether before or after the
closing) any election, consent, or agreement with respect to any Acquired
Company or any of their respective assets and properties. AmVestors agreed to
cause (i) all reserve liabilities with respect to insurance and annuity
contracts established or reflected in the books and records of AmVestors
Insurance Subsidiaries to be (A) established in accordance with the methods for
establishing liabilities and reserving methods followed by AmVestors Insurance
Subsidiaries in the preparation of the AmVestors' Annual Report and (B) adequate
(under generally accepted actuarial principles consistently applied) to cover
the total amount of all reasonably anticipated matured and unmatured benefits,
dividends, losses, claims, expenses, and other liabilities of AmVestors
Insurance Subsidiaries under all insurance and annuity contracts pursuant to
which AmVestors Insurance Subsidiaries have or will have any liability
(including without limitation any liability arising under or as a result of any
reinsurance, coinsurance, or other similar contract) and (ii) AmVestors
Insurance Subsidiaries to continue to own assets that qualify as legal reserve
assets under all applicable insurance laws in an amount at least equal to their
required reserve liabilities. AmVestors agreed to use all commercially
reasonable efforts to maintain in full force and effect until the Closing
substantially the same levels of coverage as the insurance afforded under
existing contracts previously disclosed to AmerUs pursuant to the Merger
Agreement. Any and all benefits under such contracts paid or payable to any
Acquired Company prior to the Closing with respect to the business, operations,
affairs, or assets and properties of such Acquired Company shall be paid to such
Acquired Company. AmVestors agreed to continue to and will cause the other
Acquired Companies to comply, in all material respects, with all laws applicable
to its business, operations, or affairs. AmVestors agreed to not and will cause
the other Acquired Companies not to incur any liabilities outside of the
ordinary course of their respective businesses and consistent with past
practices.
 
EXERCISE OF CALL OF AMVESTORS CONVERTIBLE DEBENTURES
 
    AmVestors agreed to cause notices of redemption to be mailed to all
registered holders of 3% convertible debentures due 2003 of AmVestors (the
"AMVESTORS CONVERTIBLE DEBENTURES") issued pursuant to the Indenture dated July
12, 1996, between AmVestors and Bank of New York, as successor trustee (the
"INDENTURE") prior to September 26, 1997, in accordance with applicable
provisions of the Indenture, and shall use its commercially reasonable efforts
to cause the redemption of all outstanding AmVestors Convertible Debentures in
accordance with the applicable provisions of the Indenture (the "REDEMPTION").
On September 24, 1997, AmVestors issued a written notice of redemption of all
the outstanding AmVestors Convertible Debentures on November 14, 1997 (the
"REDEMPTION DATE"), at a redemption price (the "REDEMPTION PRICE") equal to 100%
of their principal amount plus Accrued Current Interest (as defined in the
Indenture). All the outstanding AmVestors Convertible Debentures were converted
into shares of AmVestors Common Stock prior to the close of business on November
7, 1997 at a conversion price of $17.125 per share.

INDEMNIFICATION
 
    AmerUs has agreed in the Merger Agreement that it will, to the fullest
extent permitted by law, cause the Surviving Corporation to honor, and will
itself honor, all AmVestors' obligations to indemnify each current or former
director and officer of AmVestors or any of its Subsidiaries (each such
indemnified person, an "INDEMNIFIED PARTY" and collectively, the "INDEMNIFIED
PARTIES") for acts or omissions by such Indemnified Parties occurring prior to
the Effective Time to the extent that such obligations of AmVestors exist on the
date of the Merger Agreement, whether pursuant to AmVestors' Certificate of
Incorporation (the "AMVESTORS CHARTER"), By-Laws (the "AMVESTORS BY-LAWS") or
individual indemnity agreements. Any amendment, repeal or other modification to
the AmVestors Charter or the AmVestors By-Laws will not affect the obligations
of AmerUs and shall not adversely affect the rights of Indemnified Parties under
the Merger Agreement, unless such modification is required by law. AmerUs and
AmVestors also agreed that, for a period of six years after the Effective Time
(as defined in the Merger Agreement) (it being understood that AmVestors has
prepaid all premiums for such policies through February 17, 2000), AmerUs shall
cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by AmVestors (provided that AmerUs may
substitute therefor policies containing terms with respect to coverage and
amounts identical or more extensive to the coverage and amounts currently
provided by AmVestors' policy) with respect to claims arising from or related to
facts or events which occurred at or prior to the Effective Time; PROVIDED,
HOWEVER, that AmerUs shall not be obligated to make annual premium payments for
such insurance to the extent such premiums exceed 150% of the annual premiums
paid as of the date of the Merger Agreement by AmVestors for such insurance
(such 150% amount, the "MAXIMUM PREMIUM"), and that, to the extent such
insurance coverage cannot be obtained at all, or can only be obtained at an
annual premium in excess of the Maximum Premium, AmerUs shall maintain the most
advantageous policies of directors' and officers' insurance obtainable for an
annual premium equal to the Maximum Premium.

<PAGE>
opinion (including facts set forth in the certificates of officers), the Merger
will be treated for United States Federal income tax purposes as a

NO SOLICITATION
 
    Under the Merger Agreement, AmVestors agreed, and agreed to cause each
Acquired Company to, immediately cease and cause to be terminated any existing
activities, discussions, or negotiations by AmVestors, any Acquired Company or
any officer, director or employee of, investment banker, attorney, accountant or
other advisor or representative of, AmVestors or any Acquired Company, with
parties conducted heretofore with respect to any of the foregoing. The Merger
Agreement provides that AmVestors shall not, nor shall AmVestors authorize or
permit any of the Acquired Companies, or any of its or their officers,
directors, employees, representatives or agents, to, directly or indirectly,
encourage, solicit, participate in, initiate or continue discussions or
negotiations with, or provide any information to, any person (other than AmerUs
or Merger Sub) with respect to, or take any action to facilitate any inquiries
or the making of, or enter into any agreement (including any preliminary
agreement) relating to, or approve any proposal that constitutes, or may
reasonably be expected to lead to, any Acquisition Proposal (as defined below),
provided that, at any time prior to the approval of the Merger Agreement and the
Merger by AmVestors' stockholders at the AmVestors Special Meeting, AmVestors
may furnish information and access, in each case only in response to requests
which were not solicited on or after the date of the Merger Agreement, to any
person pursuant to a customary confidentiality agreement, and may participate in
discussions and negotiate with such person concerning an Acquisition Proposal,
if the AmVestors Board determines in its good faith judgment, following
consultation with outside counsel, that (i) such person shall have submitted a
Competitive Proposal (as defined below) which was not solicited on or after the
date of the Merger Agreement, and (ii) that it is required to do so in order to
comply with its fiduciary duties to stockholders under applicable law. The
Merger Agreement provides that the AmVestors Board shall notify AmerUs orally
(within one business day), and in writing (as promptly as practicable) of all
inquiries and proposals that it may receive relating to any Acquisition Proposal
and the material terms and conditions thereof, that it and any Acquired Company
or any of its or their officers, directors, employees, representatives or agents
may receive relating to any Acquisition Proposal and thereafter keep AmerUs
promptly advised of any material developments with respect thereto.
 
    The Merger Agreement provides that the AmVestors Board shall not withdraw or
modify, or propose to withdraw or modify, its recommendation of the Merger
Agreement and the transactions contemplated hereby or approve or recommend, or
propose to approve or recommend, any Acquisition Proposal, provided that, if the
AmVestors Board determines in its good faith judgment, following consultation
with outside counsel and an independent financial advisor, that (i) such Person
shall have submitted a Superior Proposal (as defined below) which was not
solicited on or after the date of the Merger Agreement, and (ii), that it is
required to do so in order to comply with its fiduciary duties to stockholders
under applicable law, the AmVestors Board may (x) withdraw or modify, or propose
to withdraw or modify, its recommendation of the transactions contemplated by
the Merger Agreement on account of such Superior Proposal or (y) approve or
recommend such Superior Proposal or terminate the Merger
 
                                       61
<PAGE>
Agreement (and concurrently with or after such termination, cause AmVestors to
enter into any agreement with respect to such Superior Proposal) but in each
case of the foregoing (x) and (y) only after providing at least five business
days prior written notice to AmerUs (A) advising AmerUs that the AmVestors Board
has received or become aware of a Superior Proposal, (B) specifying the material
terms and conditions of such Superior Proposal, and (C) identifying the person
making the Superior Proposal, and (D) stating that it intends to withdraw its
recommendation or approve or recommend such Superior Proposal.
 
    Such provision of the Merger Agreement does not, however, prohibit the
AmVestors Board from disclosing to AmVestors' stockholders a position permitted
thereby in accordance with Rules 14d-9 and 14e-2 promulgated under the Exchange
Act with respect to any tender offer for shares of capital stock of AmVestors.
 
    An "ACQUISITION PROPOSAL" means any proposal, offer or expression of
interest from any person involving a merger, consolidation or other business
combination with AmVestors or any other Acquired Company or any proposal, offer
or expression of interest to acquire or cause to be acquired in any manner,
directly or indirectly, including, without limitation, through any reinsurance
or coinsurance transaction, all or a significant portion of the business,
assets, or capital stock of AmVestors or any other Acquired Company, other than
the transactions contemplated by the Merger Agreement.
 
    A "SUPERIOR PROPOSAL" means any bona fide Acquisition Proposal from any
person and which is otherwise on terms that the AmVestors Board determines in
its good faith reasonable judgment, following consultation with outside counsel
and an independent financial advisor, to be more favorable to AmVestors'
stockholders than the Merger and for which financing, to the extent required, is
then committed or which, in the good faith judgment of the AmVestors Board,
based upon the advice of its financial advisors, is reasonably capable of being
obtained by such third party on commercially reasonable terms.
 
    A "COMPETITIVE PROPOSAL" means any bona fide Acquisition Proposal from any
Person that the AmVestors Board determines in its good faith reasonable
judgment, could reasonably be expected to lead to a transaction which is
financially superior to the Merger.
 
TERMINATION
 
    The Merger Agreement may be terminated at any time prior to the Effective
Time, upon notice by the terminating party to the other party:
 
        (a) at any time before the Closing, by mutual written agreement of the
    parties; or
 
        (b) at any time by AmVestors if any of the AmerUs' or Merger Sub's
    covenants or representations and warranties shall have been breached, or
    shall not have been performed or complied with, in any material respect, at
    or before the Closing Date and such breach, non-performance, or non-
    compliance has not been cured or eliminated within 30 calendar days after
    written notice thereof has been given to AmerUs, or if a condition to
    AmVestors' obligations thereunder cannot be satisfied prior to the Outside
    Date (as defined below);
 
        (c) at any time by AmerUs if any of AmVestors' covenants or
    representations and warranties shall have been breached, or shall not have
    been performed or complied with, in any material respect, before the Closing

    or eliminated within 30 calendar days after written notice thereof has been
    given to AmVestors, or if a condition to AmerUs' obligations thereunder
    cannot be satisfied prior to the Outside Date;
 
        (d) by AmerUs or AmVestors, if the Merger Agreement and the Merger shall
    have failed to receive the requisite approval of (i) the stockholders of
    AmVestors at the AmVestors Special Meeting, or (ii) the shareholders of
    AmerUs at the AmerUs Special Meeting;
 
                                       62

        (e) at any time after June 30, 1998 (the "OUTSIDE DATE") by AmVestors or
    AmerUs, if the transactions contemplated by the Merger Agreement have not
    been consummated on or before such date, provided, that the Merger Agreement
    shall be extended not more than ninety days thereafter if the Merger shall
    not have occurred as a result of the failure to receive any governmental
    approvals, and such failure to obtain approval is not caused by a breach of
    the Merger Agreement (or any representation, warranty, covenant, or
    agreement included therein) by the party electing to terminate pursuant to
    this clause (e);
 
        (f)  by AmVestors in accordance with the provisions described under
    "--No Solicitation";
 
        (g) by AmerUs if the AmVestors Board shall have withdrawn or modified
    its recommendation of the Merger Agreement or the transactions contemplated
    thereby or approves or recommends any Acquisition Proposal; or
 
        (h) by AmVestors in accordance with the Termination for Price.

incurring such fees or expenses, whether or not the Merger is consummated,
except that expenses incurred in connection with SEC filing fees, the printing
and mailing of the Joint Proxy Statement/ Prospectus shall be shared equally by
AmerUs and AmVestors.

Merger Agreement and the transactions contemplated thereby.
 
    In the event the Merger Agreement is terminated (x) by either AmVestors or
AmerUs, if the Merger Agreement and the Merger shall have failed to receive the
requisite approval of the stockholders of AmVestors at the AmVestors Special
Meeting, or (y) by either AmVestors or AmerUs at any time after the Outside Date
if the transactions contemplated by the Merger Agreement have not been
consummated on or before such date (provided in the case of clause (y) that
AmVestors' stockholders shall not have voted upon the approval of the Merger
Agreement at the AmVestors Special Meeting prior to the Outside Date and such
failure to vote was not primarily due to AmerUs' actions or inactions), (i)
AmVestors shall pay to AmerUs by wire transfer of immediately available funds

connection with the Merger Agreement and the transactions contemplated thereby

stock of any Acquired Company, or (C) any transaction which would result in the
direct or indirect acquisition by any person of the power to direct the voting
or disposition of shares of capital stock of AmVestors representing 50% or more
of the total voting power of all outstanding shares of capital stock of
AmVestors, or otherwise resulting in a change in control of AmVestors, AmVestors

instrument in writing signed on behalf of such party. The failure of any party
to the Merger Agreement to assert any of its rights under the Merger Agreement
or otherwise shall not constitute a waiver of such rights.

are derived from the consolidated financial statements of AmerUs. The
consolidated financial statements as of or for each of the four years ended

financial information presented for all interim periods reflects all adjustments
(consisting only of normal recurring adjustments) necessary for a fair

and 1996 are not necessarily indicative of results that may be expected for any
other interim period or the year as a whole. This data should be read in

(A) The merger of the two predecessor entities of AmerUs, which was consummated
    in 1994, has been accounted for as a pooling of interests transaction.
 
(B) AmerUs formed the Closed Block on June 30, 1996 as a part of the AmerUs
    Reorganization. Invested assets allocated to the Closed Block are classified
    as Closed Block assets. Revenues and expenses associated with the Closed
    Block are shown net as a single line item. Accordingly, the individual
    income statement components for the first six months of 1997 are not
    comparable with the first six months of 1996, prior to the establishment of
    the Closed Block. See "ADDITIONAL INFORMATION REGARDING
    AMERUS--Business--The AmerUs Reorganization--Establishment and Operation of
    the Closed Block," "--Management's Discussion and Analysis of Results of
    Operations and Financial Condition of AmerUs--Results of Operations--Six
    Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996," and
    "--Management's Discussion and Analysis of Results of Operations and
    Financial Condition of AmerUs--Results of Operations--1996 Compared to
    1995."
 
(C) Retroactively reflects the pro forma effect of the issuance of 18.16 million
    shares of AmerUs Class A Common Stock and 5.0 million shares of AmerUs Class
    B Common Stock at the beginning of the respective periods.
 
(D) Amounts reported prior to June 30, 1996 reflect policyowners' equity. From
    December 31, 1993, results reflect the impact of SFAS 115, "Accounting for
    Certain Investments in Debt and Equity Securities."
 
(E) Adjusted operating income adjusts net income for the after-tax effect of
    realized gains or losses on investments less that portion of the
    amortization of deferred policy acquisition costs on such amounts, the
    mutual life insurance equity add-on tax, costs directly related to the
    AmerUs Reorganization, and the cumulative effect of accounting changes of
    SFAS 106. See "ADDITIONAL INFORMATION REGARDING AMERUS--Management's
    Discussion and Analysis of Results of Operations and Financial Condition of
    AmerUs."
 
(F) Effective May 1996, substantially all new sales of individual deferred
    annuities are made through the Ameritas Joint Venture. See "SEE ADDITIONAL
    INFORMATION REGARDING AMERUS--Business--Ameritas Joint Venture."

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION
 
    The following unaudited pro forma condensed consolidated financial
statements give effect to the acquisition of Delta and the Merger of AmerUs and
AmVestors and the issuance of 11.49 million shares of AmerUs Class A Common
Stock as the Merger Consideration (assuming the Merger Consideration is .6724,
the conversion of all AmVestors Convertible Debentures and rollover of all
warrants and options to purchase shares of AmVestors Common Stock) as if the
acquisition of Delta and the Merger had occurred as of June 30, 1997 for the
purposes of the unaudited pro forma condensed consolidated balance sheet and as
of January 1, 1996 for the purposes of the unaudited pro forma condensed
consolidated statements of income for the six months ended June 30, 1997 and the
year ended December 31, 1996. The acquisition of Delta and the Merger are

reasonable and reflect the effects of the transactions described above. Such
unaudited pro forma condensed consolidated financial statements are provided for

(A) Giving effect to the acquisition of Delta under purchase accounting, the
    total purchase cost of Delta will be allocated to the assets and liabilities
    acquired based on their relative fair values as of the date of acquisition,
    with any excess of the total purchase cost over the fair value of the assets
    acquired less the fair value of the liabilities assumed recorded as
    goodwill. The cost allocations, primarily related to value of business
    acquired, investments, and goodwill, are based on studies which are not yet
    completed. Accordingly, the final allocations may differ from the amounts
    reflected herein, due to interest rate fluctuations, operating experience,
    and results of operations through the date of closing. Although the final
    allocations may differ, the pro forma financial statements reflect
    management's best estimate based on currently available information and the
    differences between the current and final allocations are not expected to be
    material.

(B) Giving effect to the Merger under purchase accounting, the total purchase
    cost of AmVestors will be allocated to the assets and liabilities acquired
    based on their relative fair values as of the date of acquisition, with any
    excess of the total purchase cost over the fair value of the assets acquired
    less the fair value of the liabilities assumed recorded as goodwill. The
    cost allocations, primarily related to value of business acquired,
    investments, and goodwill, are based on studies which are not yet completed.
    Accordingly, the final allocations may differ from the amounts reflected
    herein, due to interest rate fluctuations, operating experience, and results
    of operations through the date of closing. Although the final allocations
    may differ, the pro forma financial statements reflect management's best
    estimate based on currently available information and the differences
    between the current and final allocations are not expected to be material.
 
   It has been assumed that the Average AmerUs Trading Price was $30.275 per
    share (which represents the average of the closing prices of AmerUs common
    stock the date of the merger announcement, two days preceding and two days
    succeeding the announcement), and that therefore the Merger Consideration
    was .6724, that the number of AmVestors common stock outstanding was equal
    to the number of shares outstanding on June 30, 1997 that the $65 million
    outstanding principal amount of AmVestors Convertible Debentures were
    converted at $17.125 per share at the beginning of the respective periods
    resulting in the issuance of 3,795,620 additional shares of AmVestors Common
    Stock and that all options and warrants to acquire 2,756,636 shares of
    AmVestors Common Stock valued at their fair market value are rolled over
    into options or warrants to acquire shares of AmerUs Class A Common Stock
    with identical terms as the AmVestors options or warrants. As a result, the
    total number of shares of AmerUs Class A Common Stock issued as merger
    consideration was assumed to be 11,491,141.
 
   In the event that the holders of AmVestors' stock options and stock warrants
    elect not to rollover and instead elect to receive cash, the impact on pro
    forma earnings per share would be less than $.02
 
                                       73
<PAGE>
    per share. The total amount of funds required to cash out the stock options
    and the warrants would range from $18.9 million up to $22.6 million for the
    exchange ratio of .7407 and .6724, respectively, assuming an AmerUs Class A
    Common Stock price per share of $27 and $31.75, respectively.

The historical components of AmVestor's shareholders' equity have been eliminated in accordance with purchase
accounting. In addition, common stock is adjusted to reflect the shares issued in conjunction with the
merger's exchange of stock amounting to $11.5 million. Additional paid-in capital is also adjusted for the
excess of the merger consideration exchanged over the stated value of the AmerUs Common Stock amounting to
$336.4 million.
 
AmerUs Group has indicated its intention (depending on, among other things, market conditions and other
factors) to expend up to an aggregate of $35 million to partially offset its dilution from the Stock
Issuance, through purchases of shares of AmVestors Common Stock in public or private transactions prior to
the closing of the Merger and/or through purchases of shares of AmerUs Common Stock in public or private
transactions following the shareholders' meetings. Any such purchases would have no effect on the pro forma
financial statements or on the ownership of AmVestors by AmerUs after the Merger.

FUTURE COST SAVINGS
 
    As AmVestors operations are integrated with the existing operations of
AmerUs, management expects to achieve annual cost savings of approximately $6-8
million (pre-tax) during 1998 and additional savings beginning at the end of the
third quarter from the reduction of overhead expenses and the elimination of
redundant expenses. For instance, during 1998, expenses which can be eliminated
shortly after completing the acquisition include: (i) expenses associated with
the operation and maintenance of an aircraft, (ii) certain executive
compensation and related office expenses, (iii) operating costs of FBL at a
separate location, (iv) costs associated with filings and listings as a result
of being a publicly held entity, (v) duplicative costs of the investment
management department, and (vi) tax, license, and other fees paid to various
governmental agencies. Late in 1998, management expects to begin to consolidate
the administrative and data processing functions in order to achieve greater
operational efficiencies. Although there can be no assurance that these
projected cost savings will fall within the range provided, the expense savings
outlined above represent management's best estimate based on the currently
available information. See "SUMMARY--Forward Looking Information".

                      DESCRIPTION OF AMERUS CAPITAL STOCK
 
    THE FOLLOWING DESCRIPTION DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO AMERUS' AMENDED AND RESTATED ARTICLES OF
INCORPORATION (THE "AMERUS CHARTER"), THE AMERUS BY-LAWS (THE "AMERUS BY-LAWS")
AND TO CERTAIN PROVISIONS OF THE IOWA BUSINESS CORPORATION ACT (THE "IBCA").
 
GENERAL
 
    The authorized capital stock of AmerUs consists of 145 million shares, of
which 75 million are shares of AmerUs Class A Common Stock, 50 million are
shares of Class B Common Stock and 20 million are shares of preferred stock
("AMERUS PREFERRED STOCK"). As of the AmerUs Meeting Record Date, there are
18,155,989 shares of AmerUs Class A Common Stock outstanding, 5,000,000 shares
of AmerUs Class B Common Stock outstanding, and no shares of AmerUs Preferred
Stock outstanding. As of the AmerUs Meeting Record Date, AMHC beneficially owns
11,706,511 of the AmerUs Class A Common Stock (approximately 64% of the
outstanding shares) and 5,000,000 of the AmerUs Class B Common Stock (100% of
the outstanding), for an aggregate of approximately 72% of the AmerUs Common
Stock. In addition, 1,400,000 and 150,000 shares of AmerUs Class A Common Stock
are reserved for issuance under options granted or available for grant under the
AmerUs Stock Plan and Director Plan (each as defined below) , respectively, and
5,000,000 shares of AmerUs Class A Common Stock are reserved for issuance upon
conversion of AmerUs Class B Common Stock.
 
COMMON STOCK
 
    The powers, preferences and rights of the AmerUs Class A Common Stock and
the AmerUs Class B Common Stock and the qualifications, limitations or
restrictions thereof are identical except as otherwise provided by law and
except for provisions described below relating to voting, ownership, conversion,
dividends and relative number of shares outstanding described below.
 
    OWNERSHIP AND NUMBER OF AMERUS CLASS B COMMON STOCK.  The AmerUs Class B
Common Stock (or any interest therein) may only be owned by AMHC or a mutual
insurance holding company or intermediate holding company which is expressly
authorized by applicable law to own or have a beneficial interest in the AmerUs
Class B Common Stock (a "PERMITTED CLASS B HOLDER"). The AmerUs Charter provides
that the number of outstanding shares of AmerUs Class A Common Stock (excluding
shares of AmerUs Class A Common Stock owned by AMHC or another Permitted Class B
Holder) shall exceed the number of outstanding shares of AmerUs Class B Common
Stock plus the shares of AmerUs Class A Common Stock owned by AMHC or another
Permitted Class B Holder only as authorized by law and never by a ratio of more
than three to one (the "AMERUS CLASS RATIO").
 
    VOTING.  Each share of AmerUs Class A Common Stock entitles its holder to
one vote per share on all matters upon which shareholders are entitled to vote.
Each share of AmerUs Class B Common Stock entitles its holder to one vote per
share on all such matters except that, if on the record date for determining
shares eligible to vote, the number of outstanding shares of AmerUs Class A
Common Stock (excluding shares owned by a Permitted Class B Holder) and any
outstanding shares of AmerUs Preferred Stock having voting rights, if any
(excluding shares owned by a Permitted Class B Holder), equals or exceeds the
number of outstanding shares of AmerUs Class B Common Stock plus the number of
outstanding shares of AmerUs Class A Common Stock owned by a Permitted Class B
Holder, the voting rights for each share of AmerUs Class B Common Stock shall be
equal to the aggregate number of shares of AmerUs Class A Common Stock
(excluding shares owned by a Permitted Class B Holder) and AmerUs Preferred
Stock having voting rights, if any, then outstanding (excluding shares owned by
a Permitted Class B Holder) plus one divided by the number of outstanding shares
of AmerUs Class B Common Stock. Accordingly, even if the number of outstanding
shares of AmerUs Class A Common Stock (excluding shares owned by a Permitted
Class B Holder) exceeds the number of outstanding shares of AmerUs Class B
Stock, the Permitted Class B Holder will always have a majority of the votes.
The AmerUs Charter also generally provides that the shares of AmerUs Class B
Common Stock plus outstanding shares of AmerUs Class A Common Stock owned by a
Permitted Class B Holder
 
                                       78
<PAGE>
shall at all times carry the right to cast at least 50.1% of the votes of the
outstanding shares of capital stock of AmerUs.
 
    Holders of each class of AmerUs Common Stock generally vote together as a
single class on all matters. However, the holders of AmerUs Class A Common Stock
and the holders of AmerUs Class B Common Stock will vote separately as a class
with respect to (i) amendments to the AmerUs Charter that alter or change the
powers, preferences or special rights of their respective class of stock so as
to affect them adversely, and (ii) certain matters for which class voting is
required under Iowa law, including (x) approval of proposed amendments to AmerUs
Charter that, among other things, would alter the designation, rights,
preferences or limitations of all or part of the shares of their respective
class, increase or decrease the aggregate number of authorized shares of such
class, effect an exchange or reclassification or create a right of exchange of
all or part of the shares of one class into shares of another class, create a
new class of shares or increase the rights, preferences, or number of authorized
shares of any existing class so that it would have rights or preferences with
respect to distribution or to dissolution that are prior, superior, or
substantially equal to, the shares of such class; (y) approval of a proposed
plan of merger or consolidation if such plan contains any provisions which, if
contained in a proposed amendment to the AmerUs Charter, would entitle such
class of shares to vote as a class (with certain limited exceptions for
shareholders of the surviving corporation); and (z) approval of a plan of share
exchange (to be voted upon by each class included in the exchange). In addition,
the provision of the AmerUs Charter relating to the AmerUs Class Ratio may not
be amended without the approval of holders of both a majority of the AmerUs
Common Stock and a majority of the shares of AmerUs Class A Common Stock
(excluding shares held by a Permitted Class B Holder).
 
    The AmerUs Charter does not permit cumulative voting in the election of
directors.
 
    DISTRIBUTIONS.  No cash dividends may be declared in any fiscal year on the
AmerUs Class B Common Stock until and unless a cash dividend has been declared
on the AmerUs Class A Common Stock. Any cash dividends will be declared and paid
equally on both classes. The classes of AmerUs Common Stock will rank equally
and have equal rights with respect to distributions, including distributions
upon liquidation of AmerUs. However, in the case of dividends or other
distributions payable on the AmerUs Common Stock in shares of such stock,
including distributions pursuant to stock splits or stock dividends, only AmerUs
Class A Common Stock will be distributed with respect to AmerUs Class A Common
Stock and only AmerUs Class B Common Stock will be distributed with respect to
AmerUs Class B Common Stock. In no event will either class of AmerUs Common
Stock be split, divided or combined unless the other is split, divided or
combined equally.
 
    OTHER.  So long as the number of outstanding shares of AmerUs Class A Common
Stock (excluding shares owned by a Permitted Class B Holder) shall exceed the
number of outstanding shares of AmerUs Class B Common Stock plus the outstanding
shares of AmerUs Class A Common Stock owned by AMHC or another Permitted Class B
Holder only as authorized by law and never by a ratio of more than three to one,
the AmerUs Class B Common Stock will be convertible at all times into AmerUs
Class A Common Stock on a share-for-share basis by surrender of certificates to
the transfer agent for AmerUs. Therefore, shareholders who subsequently desire
to sell some or all of their shares of AmerUs Class B Common Stock may convert
those shares into an equal number of shares of AmerUs Class A Common Stock and
sell the shares of AmerUs Class A Common Stock in the public market. AmerUs will
be required to reserve shares of AmerUs Class A Common Stock sufficient for
issuance upon conversion of AmerUs Class B Common Stock.
 
    The AmerUs Charter provides that a Permitted Class B Holder has the
preemptive rights as described in "COMPARISON OF SHAREHOLDER RIGHTS--Preemptive
Rights." The AmerUs Intercompany Agreement also affords the AmerUs Affiliated
Group certain equity purchase rights. See "ADDITIONAL INFORMATION REGARDING
AMERUS--Business--Certain Transactions and Relationships--AmerUs Intercompany
Agreement."
 
    In the event that AMHC (or any successor mutual insurance holding company)
is demutualized and is converted into a stock company pursuant to Iowa law, then
immediately upon such conversion each
 
                                       79
<PAGE>
share of the AmerUs Class B Common Stock shall automatically be converted into
one share of AmerUs Class A Common Stock. AMHC has advised AmerUs that AMHC has
no present plans to demutualize.
 
    Any conveyance, transfer, assignment, pledge, security interest, lien,
encumbrance or hypothecation or alienation by AMHC or any intermediate holding
company, in or on any of the shares of AmerUs Common Stock which would result in
AMHC not holding the right, directly or indirectly, to cast a majority of the
votes entitled to be cast in respect of all outstanding capital stock of AmerUs
Life shall be deemed void in inverse chronological order from the date of such
transaction to the extent necessary to give AMHC unencumbered direct or indirect
ownership of a majority of such voting shares.
 
PREFERRED STOCK
 
    The AmerUs Board is authorized, subject to any limitations prescribed by
law, from time to time to issue up to an aggregate of 20 million shares of
AmerUs Preferred Stock in one or more series, each of such series to have such
voting powers, full or limited, or no voting powers, and such designations,
preferences and relative, participating, optional or other special rights, and
such qualifications, limitations or restrictions thereof, as shall be determined
by the AmerUs Board in a resolution or resolutions providing for the issue of
such AmerUs Preferred Stock; provided, however, that no AmerUs Preferred Stock
may have more than one vote per share. As a result, any class or series of
AmerUs Preferred Stock could have rights which would adversely affect the rights
of the holders of the AmerUs Class A Common Stock. The issuance of a new series
of AmerUs Preferred Stock, while providing desirable flexibility in connection
with possible acquisitions or other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or discouraging a third
party from acquiring, a majority of the outstanding voting stock of AmerUs.
 
CAPITAL SECURITIES OF AMERUS CAPITAL I
 
    AmerUs Capital I, a Delaware business trust and a wholly-owned subsidiary of
AmerUs, issued $86 million of Capital Securities in 1997 as part of AmerUs'
financing plan. The assets of the Trust are invested in Junior Subordinated
Debentures of AmerUs, which debt securities have a stated maturity of thirty
years. If AmerUs redeems all or a portion of the Junior Subordinated Debentures,
the Trust must redeem a corresponding amount of the Capital Securities.
 
INDEMNIFICATION AND LIMITATION OF LIABILITY
 
    The AmerUs Charter provides that no director of AmerUs shall be liable to
AmerUs or its shareholders for monetary damages for any breach of fiduciary duty
as a director, except to the extent otherwise required by the IBCA. This
provision does not prevent shareholders from obtaining injunctive or other
equitable relief against directors nor does it shield directors from liability
under Federal or state securities laws. In addition, the AmerUs Charter provides
that AmerUs shall, to the maximum extent permitted by law, indemnify any person
who incurs any loss by reason of the fact that he is or was or has agreed to be
a director or officer of AmerUs or while a director or officer of AmerUs is or
was serving at the request of AmerUs as a director, officer, partner, trustee,
employee or agent of any corporation, partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, subject to
such person having met the standards of conduct required for such
indemnification under Iowa law.
 
TRANSFER AGENT AND REGISTRAR
 
    The Transfer Agent and Registrar for the AmerUs Class A Common Stock is
ChaseMellon Shareholder Services, L.L.C.
 
AMVESTORS WARRANTS
 
    As of November 10, 1997, AmVestors has issued and outstanding warrants to
acquire up to 896,704 shares of AmVestors Common Stock (the "AMVESTORS
WARRANTS"), including the Public Warrants (which are publicly traded on the
Nasdaq Small Cap Market under the symbol "AMVWW") to acquire up to
 
                                       80
<PAGE>
716,318 shares of AmVestors Common Stock. Following the Merger and subject to
certain cash-out rights, upon exercise of any AmVestors Warrant, each holder
shall have the right to receive a number of shares of AmerUs Class A Common
Stock equal to the Merger Consideration. If the Merger Consideration were equal
to 0.7407 and no warrants were cashed-out, the AmVestors Warrants would be
convertible into an aggregate of 664,188 shares of AmerUs Class A Common Stock.
If the Merger Consideration were equal to 0.6724 and no warrants were
cashed-out, the AmVestors Warrants would be convertible into an aggregate of
602,943 shares of AmerUs Class A Common Stock. For additional information
concerning the AmVestors Warrants, see "WHERE YOU CAN FIND MORE INFORMATION."

                        COMPARISON OF SHAREHOLDER RIGHTS
 
    THE STATEMENTS SET FORTH UNDER THIS HEADING WITH RESPECT TO THE IBCA, THE
AMERUS CHARTER AND THE AMERUS BY-LAWS, AND THE KANSAS GENERAL CORPORATION CODE
(THE "KGCC"), THE AMVESTORS ARTICLES OF INCORPORATION (THE "AMVESTORS CHARTER")
AND THE AMVESTORS BY-LAWS (THE "AMVESTORS BY-LAWS") ARE BRIEF SUMMARIES THEREOF
AND DO NOT PURPORT TO BE COMPLETE AND ARE QUALIFIED IN THEIR ENTIRETY BY
REFERENCE TO THE RELEVANT PROVISIONS OF THE IBCA, THE AMERUS CHARTER, THE AMERUS
BY-LAWS, THE KGCC, THE AMVESTORS CHARTER AND THE AMVESTORS BY-LAWS, AS
APPROPRIATE.
 
GENERAL
 
    AmerUs is incorporated under the laws of the State of Iowa. AmVestors is
incorporated under the laws of the State of Kansas. If the Merger is
consummated, the stockholders of AmVestors will become shareholders of AmerUs.
As shareholders of an Iowa corporation, their rights will differ in certain
respects from those of stockholders of a Kansas corporation. In addition, the
rights of stockholders of AmVestors who become shareholders of AmerUs following
the Merger will be governed by the AmerUs Charter and the AmerUs By-Laws rather
than the provisions of the AmVestors Charter and the AmVestors By-Laws.
 
CAPITAL STOCK
 
    The authorized capital stock of AmerUs consists of 145 million shares, of
which 75 million are shares of AmerUs Class A Common Stock, 50 million are
shares of AmerUs Class B Common Stock and 20 million are shares of AmerUs
Preferred Stock. For further information concerning AmerUs capital stock, see
"DESCRIPTION OF AMERUS CAPITAL STOCK."
 
    The authorized capital stock of AmVestors consists of 27 million shares, of
which 2 million are shares of AmVestors Preferred Stock and 25 million are
shares of AmVestors Common Stock. Each share of AmVestors Common Stock is
entitled to one vote on all matters presented to the stockholders. The holders
of AmVestors Common Stock have cumulative voting rights in the election of
directors. Thus, each holder of AmVestors Common Stock is entitled to the number
of votes equaling the number of shares of AmVestors Common Stock he or she holds
multiplied by the number of directors to be elected, and he or she may cast all
of such votes for a single director or may distribute them among the number of
directors to be voted for, or for any two or more of them.
 
AMENDMENT OF GOVERNING DOCUMENTS
 
    CERTIFICATES OF INCORPORATION.  Under the IBCA, amendments to the articles
of incorporation generally must be recommended by the board of directors and
approved by the shareholders. If the proposed amendment would not create
dissenters' rights with respect to a voting group entitled to vote, for a
proposed amendment to be approved by such voting group, more votes of such group
must be cast in favor of the proposed amendment than against, provided a quorum
is present. If the proposed amendment would create dissenters' rights in one or
more voting groups, the shareholders in such voting groups must approve the
amendment by a majority of the votes entitled to be cast on the amendment. In
either case, the articles of incorporation or a by-law adopted by the
shareholders or the board of directors may require a greater vote. Under the
IBCA, unless otherwise provided, certain specified amendments to the articles of
incorporation may be made by the board of directors (without shareholder
approval). In addition, certain specified amendments affecting the rights of
holders of a class of securities must be approved by vote of holders of shares
of such class entitled to vote thereon, even though they ordinarily would not
have voting rights.
 
    Under the KGCC, except for certain specified matters, an amendment or change
to a corporation's articles of incorporation must be adopted by resolution
declaring its advisability by the board of directors of the corporation,
followed by a vote of the majority of all outstanding shares entitled to vote
thereon at a meeting of stockholders. In addition, certain specified amendments
affecting the rights of holders of a
 
                                       82
<PAGE>
class of securities must be approved by vote of the majority of all outstanding
shares of such class entitled to vote thereon, even though they ordinarily would
not have voting rights.
 
    The AmerUs Charter reserves the right to amend any provision contained
therein in the manner prescribed by statute, but it requires the affirmative
vote of at least a majority of all the outstanding shares of AmerUs Class A
Common Stock and AmerUs Class B Common Stock and the affirmative vote of at
least a majority of the outstanding shares of AmerUs Class A Common Stock
(excluding outstanding shares of AmerUs Class A Common Stock owned by any
Permitted Class B Holder) to amend or repeal the provision of the AmerUs Charter
relating to the AmerUs Class Ratio.
 
    Under the AmVestors Charter, any proposal to amend or repeal certain
provisions of the AmVestors Charter including provisions relating to business
combinations (including factors to be considered by the directors when
evaluating any offer of another party to make an acquisition proposal), the size
of the board of directors, removal of directors and indemnification of directors
requires the affirmative vote of not less than two-thirds of the outstanding
shares entitled to vote in the election of directors.
 
    BY-LAWS.  Under the IBCA, a corporation's board of directors may amend or
repeal the corporation's by-laws, except to the extent otherwise provided in the
articles of incorporation or the IBCA ,or a by-law adopted by the shareholders,
and except that a by-law adopted or amended by the shareholders which fixes a
greater quorum or voting requirement for shareholders or voting groups of
shareholders than is required by the articles of incorporation may not be
adopted, amended or repealed by the board of directors. A by-law that fixes a
greater quorum or voting requirement for the board of directors may be amended
or repealed (i) if originally adopted by the shareholders, only by the
shareholders, and (ii) if originally adopted by the board of directors, by the
board of directors or the shareholders, except that such by-law, if adopted by
the shareholders, may provide that it may be amended or repealed only by a
specified vote of either the shareholders or the board of directors. A
corporation's shareholders may amend or repeal the corporation's by-laws even
though the by-laws may also be amended or repealed by the board of directors.
 
    Under the KGCC, by-laws may be adopted, amended or repealed by the
stockholders entitled to vote. When provided by the certificate of
incorporation, the board of directors may also adopt, amend or repeal by-laws.
 
    By their terms, the AmerUs By-Laws may be amended or repealed by the AmerUs
Board or by the shareholders of AmerUs, provided, however, that the shareholders
may from time to time specify particular provisions of the AmerUs By-Laws which
shall not be amended or repealed by the AmerUs Board.
 
    The AmVestors By-Laws do not provide for the adoption, amendment or repeal
of the AmVestors By-Laws by the AmVestors Board.
 
DIRECTORS
 
    NUMBER AND ELECTION; CLASSIFICATION.  The AmerUs Charter and AmerUs By-Laws
provide for the classification of the AmerUs Board into three classes. Each
class has a three-year term expiring on the date of the third annual meeting of
stockholders succeeding their election. The AmerUs Charter also provides that
the number of directors shall be fixed from time to time by the AmerUs Board,
but may not consist of less than seven nor more than 21 persons. Currently, the
number of AmerUs directors is ten (with one vacancy). The AmerUs Charter
provides that there shall be no cumulative voting in the election of directors.
The foregoing provisions cannot be altered, amended or repealed without the
affirmative vote of the majority of the holders of the outstanding voting
securities of AmerUs.
 
    The AmVestors Charter and AmVestors By-Laws provide for the classification
of the AmVestors Board into three classes. Each class has a three-year term
expiring on the date of the third annual meeting of stockholders succeeding
their election. The AmVestors By-Laws provide that the number of directors shall
be fixed from time to time by the AmVestors Board, but may not consist of less
than three
 
                                       83
<PAGE>
nor more than 13 persons. Currently, the number of AmVestors directors is 11.
The AmVestors By-Laws provide that all directors of AmVestors must be AmVestors
stockholders. The AmVestors By-Laws provide that no person shall be qualified to
serve as a director of AmVestors who is a director, officer or employee of any
life insurance company, or life insurance holding company, unless by a
two-thirds vote the AmVestors Board waives this prohibition for that person. No
director of AmVestors may concurrently be a director, officer or employee of any
life insurance company, or life insurance holding company, unless the AmVestors
Board waives this prohibition for that director of AmVestors. The AmVestors
Charter provides that cumulative voting rights shall be afforded stockholders at
all elections of directors. The foregoing provisions cannot be altered, amended
or repealed without the affirmative vote of two-thirds of the holders of the
outstanding shares of AmVestors Common Stock entitled to vote in the election of
directors, except to increase the number of classes into which the AmVestors
Board is divided.
 
    REMOVAL; VACANCIES.  Under the IBCA, any or all directors may be removed,
with or without cause, by the shareholders unless the articles of incorporation
provide that directors may be removed only for cause, except that (i) if
cumulative voting is authorized, a director shall not be removed if the number
of votes sufficient to elect that director under cumulative voting is voted
against the director's removal and (b) if cumulative voting is not authorized, a
director may be removed only if the number of votes cast to remove that director
exceeds the number of votes cast not to remove the director. The AmerUs By-Laws
provide that directors shall be subject to removal, with or without cause, in
the manner prescribed by law. The AmerUs Charter does not provide that directors
may be removed only for cause.
 
    The IBCA provides that, unless the articles of incorporation of a
corporation provide otherwise, vacancies on the board of directors, including
those resulting from an increase in the number of directors, may be filled by a
vote of the board of directors or the shareholders. If the number of directors
then in office is less than a quorum, the vacancies may be filled by a vote of a
majority of directors then in office. If the vacant office was held by a
director elected by a voting group of shareholders, only the holders of shares
of that voting group are entitled to fill the vacancy if it is filled by the
shareholders. A director elected to fill a vacancy shall hold office until the
next meeting of stockholders, and until his successor has been elected and
qualified. The AmerUs Charter and the AmerUs By-Laws provide that any vacancy in
the AmerUs Board may be filled only by a vote of the AmerUs Board, provided a
quorum is present, or by a majority of directors then in office, if less than a
quorum is then in office, or by a sole remaining director. In addition, the
AmerUs Charter provides that if the number of directors is changed, any increase
or decrease shall be apportioned among the three classes by a two-thirds vote of
the directors then in office.
 
    The KGCC provides that any or all directors may be removed, with or without
cause, by the holders of a majority of the shares then entitled to vote at an
election of directors, except that (a) in the case of a corporation whose board
is classified, any or all directors may only be removed for cause by vote of the
stockholders and a director may be removed without cause by a shareholder vote
only if the certificate of incorporation or the by-laws so provide and (b) in
the case of a corporation having cumulative voting for directors, if less than
the entire board is to be removed, no director may be removed without cause if
the votes cast against such director's removal would be sufficient to elect such
director if then cumulatively voted at an election of the entire board of
directors, or, if there be classes of directors, at an election of the class of
directors of which such director is a part. The AmVestors Charter provides that
directors may be removed only for cause by the holders of two-thirds of the
outstanding shares of capital stock of AmVestors entitled to vote in the
election of directors, or only for cause by a majority of the AmVestors Board.
The AmVestors Charter and the AmVestors By-Laws do not provide for the removal
of directors without cause by a stockholder vote.
 
    The KGCC provides that a vacancy on the board of directors shall be filled
as the by-laws of the corporation provide and, in the absence of such provision,
the vacancy shall be filled (i) by a majority of directors then in office or
(ii) whenever the holders of any class or classes of stock or series thereof are
entitled to elect one or more directors by the AmVestors Charter, by a majority
of the directors elected by such class or classes or series thereof then in
office, or by a sole remaining director so elected. The
 
                                       84
<PAGE>
AmVestors Charter and the AmVestors By-Laws provide that any vacancies in the
board shall be filled by a majority vote of the directors then in office, even
if less than a quorum. The AmVestors By-Laws provide that a director elected to
fill a vacancy shall hold office until the next election of the class for which
such director shall have been chosen, and until his successor has been elected
and qualified.
 
    FIDUCIARY DUTIES.  Under the IBCA, a director must perform his duties as a
director, including his duties as a member of any committee of the board upon
which he may serve, in good faith and with the care which an ordinarily prudent
person in a like position would exercise under similar circumstances and in a
manner the director reasonably believes to be in the best interests of the
corporation. A director shall not be considered to be acting in good faith if he
has knowledge concerning the matter in question that would cause such reliance
to be unwarranted. A person who so performs his duties shall have no liability
by reason of being or having been a director of the corporation.
 
    The KGCC provides that a director, in determining what is in the best
interest of the corporation when considering a tender offer or proposal of
acquisition, merger, consolidation, or similar proposal, shall consider any or
all of the following community interest factors, in addition to consideration of
the effects of any action on stockholders: (a) the effects of the action on the
corporation's employees, suppliers, creditors and customers, (b) the effects of
the action on the communities in which the corporation operates and (c) the
long-term as well as short-term interests of the corporation and its
stockholders, including the possibility that these interests may be best served
by the continued independence of the corporation. The consideration of any or
all of the community interest factors is not a violation of the business
judgment rule or of any duty of the director to the stockholders, or a group of
stockholders, even if the director reasonably determines that a community
interest factor or factors outweigh the financial or other benefits to the
corporation or a stockholder or group of stockholders.
 
    The AmVestors Charter provides that the AmVestors Board, when evaluating any
offer of another party to make an Acquisition Proposal (as defined below),
shall, in connection with the exercise of its judgment in determining what is in
the best interests of AmVestors as a whole, be authorized to give due
consideration to such factors as the AmVestors Board determines to be relevant,
including, without limitation: (i) the interests of AmVestors' stockholders;
(ii) whether the proposed transaction might violate federal or state laws; (iii)
the consideration being offered in the proposed transaction, in relation not
only to the then current market price, but also to certain other factors bearing
on securities prices and the corporation's financial and future prospects; and
(iv) the effects upon employees, suppliers, customers and the communities.
"Acquisition Proposal" means any proposal of any person to (1) make a tender
offer or exchange offer for any equity security of AmVestors; (2) merge or
consolidate with another corporation, or (3) purchase or otherwise acquire all
or substantially all of the properties and assets of AmVestors. This provision
of the AmVestors Charter may not be altered, amended or repealed by the
stockholders except by a vote of two-thirds of the outstanding shares of
AmVestors entitled to vote in the election of directors.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
    Special meetings of the AmerUs shareholders may be called at any time by the
AmerUs Board, by the Chairman of the Board or by the Chief Executive Officer of
AmerUs, and shall be called by the AmerUs Board upon the written demand, signed,
dated and delivered to the Secretary of AmerUs, of the holders of at least ten
percent of all the votes entitled to be cast on any issue proposed to be
considered at the meeting.
 
    The AmVestors By-Laws provide that special meetings may be called by the
Chairman of the Board or upon the request of stockholders owning at least fifty
percent of the outstanding stock of AmVestors entitled to vote at such meeting
by the President or the Secretary or the Treasurer.
 
NOMINATIONS OF DIRECTORS AND BUSINESS PRESENTED AT ANNUAL MEETINGS
 
    The AmerUs By-Laws generally provide that notice of nominations for the
AmerUs Board, other than nominations by the AmerUs Board or a committee thereof,
must be received by AmerUs, together with
 
                                       85
<PAGE>
certain other information, not less than 30 days prior to the meeting at which
such directors are to be elected. In the event that less than 40 days' notice or
prior disclosure of the date of the meeting is given, notice by the shareholders
must be received by AmerUs not later than the close of business on the tenth day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made, whichever first occurs.
 
    The AmerUs By-Laws also generally provide that notice of any business
proposed to be brought before an annual meeting of shareholders other than by or
at the direction of the AmerUs Board or a committee thereof, must be received by
AmerUs, together with certain other information, not less than 30 days prior to
the meeting at which such proposal is to be introduced. In the event less than
40 days' notice or prior public disclosure of the date of the meeting is given,
notice by the shareholder must be received by AmerUs not later than the close of
business on the tenth day following the day on which such notice of the date of
the meeting was mailed or such public disclosure was made, whichever first
occurs.
 
    Neither the AmVestors Charter nor the AmVestors By-Laws contain provisions
similar to those described in the two preceding paragraphs.
 
PREEMPTIVE RIGHTS
 
    Under the IBCA, the shareholders of an Iowa corporation do not have a
preemptive right to acquire the corporation's unissued shares, except to the
extent the articles of incorporation so provide. The AmerUs Charter provides
that so long as AMHC is a mutual insurance holding company within the meaning of
the Iowa Code, AMHC or any Permitted Class B Holder shall have the preemptive
right to purchase unissued shares of voting stock (including, without
limitation, AmerUs Class A Common Stock
and AmerUs Class B Common Stock) or any securities convertible into or
exchangeable for shares of voting stock or any options, warrants or rights to
acquire shares of voting stock ("EQUITY PURCHASE RIGHTS") to the extent required
for AMHC or any Permitted Class B Holder to comply with the provision of the
AmerUs Charter which states that, except as otherwise permitted in such articles
of incorporation, the number of outstanding shares of AmerUs Class A Common
Stock (excluding shares of AmerUs Class A Common Stock owned by a Permitted
Class B Holder) shall exceed the number of outstanding shares of AmerUs Class B
Common Stock plus outstanding shares of AmerUs Class A Common Stock owned by a
Permitted Class B Holder only as authorized by law and never by a ratio of more
than three to one. AmerUs is authorized and empowered to enter into an agreement
with AMHC and/or a Permitted Class B Holder relating to Equity Purchase Rights.
 
    Kansas law does not provide for preemptive rights to acquire a corporation's
unissued stock. However, such right may be expressly granted to the stockholders
in a corporation's articles of incorporation. The AmVestors Charter does not
provide for preemptive rights.
 
DIVIDENDS AND DISTRIBUTIONS
 
    Under the IBCA, a corporation may make distributions to its shareholders
subject to restriction by the articles of incorporation and subject to the
further limitation that no distribution may be made if, after giving it effect,
(i) the corporation would not be able to pay its debts as they become due in the
usual course of business or (ii) the corporation's total assets would be less
than the sum of its liabilities plus (unless the articles of incorporation
permit otherwise) the amount that would be needed, if the corporation were to be
dissolved at the time of the distribution, to satisfy the preferential rights
upon dissolution of shareholders whose preferential rights are superior to those
receiving the distribution.
 
    Other than the restrictions imposed by Kansas law, neither the AmVestors
Charter nor the AmVestors By-Laws contain additional restrictions on the
declaration or payment of dividends.
 
    The KGCC provides that the directors of every corporation, subject to any
restrictions contained in its articles of incorporation, may declare and pay
dividends upon the shares of its capital stock either (1) out of its surplus, or
(2) in case there shall be no such surplus, out of its net profits for the
fiscal year in which the dividend is declared or the preceding fiscal year. If
the capital of the corporation shall have
 
                                       86
<PAGE>
been diminished by depreciation in the value of its property, or by losses, or
otherwise, to an amount less than the aggregate amount of the capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets, the directors of such corporation
shall not declare and pay out of such net profits any dividends upon any shares
of any classes of its capital stock until the deficiency in the amount of
capital represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets shall have been repaired.
 
DISSENTERS' RIGHTS
 
    Under the IBCA, a shareholder is entitled to dissent from, and obtain
payment of the fair value of the shareholder's shares in the event of: (a) the
consummation of a plan of merger if (i) shareholder approval is required for the
merger and the shareholder is entitled to vote thereon or (ii) the corporation
is a subsidiary that is merged with its parent; (b) the consummation of a plan
of share exchange if the shareholder is entitled to vote on the plan; (c) the
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; or (d) an amendment
of the articles of incorporation that materially and adversely affects rights in
respect of a dissenter's shares. A dissenting shareholder is not entitled to
challenge the corporate action creating the shareholder's entitlement to dissent
unless the action is unlawful or fraudulent with respect to the shareholder or
the corporation.
 
    The KGCC provides that a stockholder has the right to dissent from any
merger or consolidation and receive the fair value of the stockholder's stock on
the effective date of the merger or consolidation unless the shares of any class
or series of a class of stock which, at the record date fixed to determine the
stockholders entitled to receive notice of and to vote at the meeting of
stockholders at which the agreement of merger or consolidation is to be acted
on, were either (a) registered on a national securities exchange or designated
as a national market system security on an interdealer quotation system by
Nasdaq or (b) held of record by not less than 2,000 stockholders, unless the
articles of incorporation of the corporation issuing such stock shall otherwise
provide. Notwithstanding (a) and (b) above, dissenters' rights are available if
under the terms of a merger or consolidation, such stockholders are required to
accept for such stock anything except (i) stock or stock and cash in lieu of
fractional shares of the corporation surviving or resulting from the merger or
consolidation; (ii) stock or stock and cash in lieu of fractional shares of any
other corporation, which at the record date fixed to determine the stockholders
entitled to receive notice of and to vote at the meeting of stockholders at
which the agreement of merger or consolidation is to be acted on, were either
registered on a national securities exchange or held of record by not less than
2,000 stockholders or (iii) a combination of stock or stock and cash in lieu of
fractional shares as set forth in (i) and (ii) above.
 
                                       87
<PAGE>
INDEMNIFICATION AND LIMITATION OF LIABILITY
 
    For information concerning indemnification for certain individuals
affiliated with AmerUs, by AmerUs and limitation of liability, see "DESCRIPTION
OF AMERUS CAPITAL STOCK."
 
    The AmVestors By-Laws provide that AmVestors may indemnify any person who
was or is a party, or is threatened to be made a party, to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, other than an action by or in the right of the
corporation, by reason of the fact that such person is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, including attorneys' fees, if
such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation; and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
such person's conduct was unlawful.
 
    In addition, the AmVestors By-Laws provide that AmVestors may indemnify any
person who was or is a party, or is threatened to be made a party, to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person is or was a director or officer of the corporation, or is or was serving
at the request of the corporation as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise against
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of such action or suit, including attorneys' fee, if such
person acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.
 
    Any indemnification under the above provisions, unless ordered by a court,
shall be made by a determination in accordance with the procedures set forth in
the KGCC.
 
    As permitted under the KGCC, the AmVestors Charter provides that no director
shall be personally liable to AmVestors or any of its stockholders for monetary
damages for breach of duty as a director, provided that such elimination of
liability shall not be applicable (i) for a breach of the director's duty of
loyalty to the corporation or its stockholders; (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law; (iii) under the provisions of Section 17-6424 of the KGCC and amendments
thereto or (iv) for any transaction from which the director derived an improper
personal benefit. Section 17-6424 of the KGCC provides joint and several
director liability for the directors under whose administration any willful or
negligent violation of the provisions of the KGCC dealing with (i) the
limitations on the powers of a corporation respecting its own stock, (ii) the
payment of dividends and (iii) the retirement by a corporation of shares of
capital stock of such corporation, occurs.
 
PROVISIONS APPLICABLE TO BUSINESS COMBINATIONS AND CHANGES IN CONTROL
 
    Under Iowa law and the AmerUs Charter, AMHC must retain directly or
indirectly ownership of shares of AmerUs capital stock which carry the right to
cast a majority of the votes entitled to be cast by all outstanding shares of
AmerUs capital stock unless AMHC elects to demutualize. See "DESCRIPTION OF
AMERUS CAPITAL STOCK." Any merger or acquisition of AmerUs by another entity or
the acquisition or attempted acquisition of more than 10% of the stock of AmerUs
is subject to regulatory approval by the Iowa Commissioner. See "ADDITIONAL
INFORMATION REGARDING AMERUS--Business-- Supervision and Regulation."
 
                                       88
<PAGE>
    Generally under the KGCC, a merger requires the approval of holders of a
majority of the outstanding stock of each corporation entitled to vote thereon.
However, approval of the stockholders of the surviving corporation is not
required if certain criteria are met, including the requirement that either no
shares of common stock of the surviving corporation and no shares, securities or
obligations convertible into such stock are to be issued or delivered under the
plan of merger, or the authorized unissued shares or the treasury shares of
common stock of the surviving corporation to be issued or delivered under the
plan of merger plus those initially issuable upon conversion of any other
shares, securities or obligations to be issued or delivered under such plan do
not exceed 20% of the shares of common stock of such constituent corporation
outstanding immediately prior to the effective date of the merger.
 
    In addition to any action required by law, the AmVestors Charter contains a
provision that requires the affirmative vote of the holders of at least
two-thirds (2/3) of the then outstanding shares of capital stock of AmVestors
entitled to vote generally in the election of directors as a condition for
Business Combinations (defined below) involving AmVestors and an Interested
Stockholder (defined below). For purposes of this provision of the AmVestors
Charter, "BUSINESS COMBINATION" is defined to mean: (i) any merger or
consolidation involving AmVestors or any of its subsidiaries with or into an
Interested Stockholder (as defined below) or any entity that is or after such
transaction would be an Affiliate (as defined below) of an Interested
Stockholder; (ii) any sale, lease, exchange, pledge, transfer or other
disposition by AmVestors or any of its subsidiaries of more than 25% of the fair
market value of its total assets; (iii) any sale, lease, exchange, transfer or
disposition of more than 25% of the fair market value of the total assets of an
Interested Stockholder to AmVestors or any subsidiary; (iv) the issuance or
transfer by AmVestors or any subsidiary of any securities of AmVestors or any
subsidiary to an Interested Stockholder in exchange for cash, securities or
other properties; (v) any merger or consolidation of an Interested Stockholder
or any Affiliate of any Interested Stockholder with or into AmVestors or any
subsidiary of AmVestors; (vi) any reclassification of securities, or
recapitalization of AmVestors, or any merger or consolidation of AmVestors with
any of its subsidiaries or any other transaction which would have the effect of
increasing the voting power of an Interested Stockholder or any Affiliate of any
Interested Stockholder; (vii) the adoption of any plan or proposal for the
liquidation or dissolution of AmVestors proposed by or on behalf of an
Interested Stockholder or any Affiliate of any Interested Stockholder; and
(viii) any agreement, contract or other arrangement providing for any of the
transactions described above. For purposes of this provision of the AmVestors
Charter, an "INTERESTED STOCKHOLDER" is defined generally to mean any person who
or which is the beneficial owner of five percent (5%) or more of AmVestors'
voting stock.
 
    The requirement of the affirmative vote of the holders of at least
two-thirds (2/3) of the then outstanding shares of capital stock of AmVestors
entitled to vote generally in the election of directors can be waived in certain
circumstances where: (a) the Business Combination is approved by a majority of
the directors unaffiliated with the Interested Stockholder or (b) the Business
Combination is solely between AmVestors and another corporation 100% of which is
owned either directly or indirectly by AmVestors; or (c) certain minimum price
and procedural requirements are met. For purposes of this provision of the
AmVestors Charter, the term "AFFILIATE" has the same meaning ascribed to such
term in Rule 12b-2 of the General Rules and Regulations under the Securities
Exchange Act of 1934.
 
STATE ANTI-TAKEOVER LAWS
 
    IOWA BUSINESS COMBINATION ACT.  AmerUs is subject to Section 490.1109 of the
IBCA, which imposes a three-year moratorium on business combinations between an
Iowa corporation and an "Interested Shareholder" (defined generally as a person
with 15% or more of a corporation's outstanding voting stock). Section 490.1108
of the IBCA provides that in considering acquisition proposals, directors may
consider, in addition to the consideration of the effects of any action on
shareholders, the effects on the company's employees, suppliers, creditors,
customers and the communities in which it operates, as well as the long-term and
short-term interests of the company. Consideration of any or all community
interest factors is not a violation of the business judgment rule, even if the
directors reasonably determine that effects on a community or other factors
outweigh the financial or other benefits to the
 
                                       89
<PAGE>
company or a shareholder or group of shareholders. Section 490.624A of the IBCA
also includes authorization of "poison pills" which include, without limitation,
terms and conditions of stock rights or options issued by a corporation that
preclude or limit the exercise, transfer or receipt of stock rights by persons
owning or offering to acquire a specified number or percentage of a
corporation's outstanding shares.
 
    Under Iowa law, no business combination (defined to include mergers, sales
of assets, sales of outstanding stock, and loans) involving AmerUs and an
Interested Shareholder (defined to include any holder of 15% or more of its
voting stock) may be entered into within three years of the time the shareholder
became an interested shareholder unless: (a) the business combination or the
purchase of shares which resulted in the shareholder becoming an interested
shareholder is approved by the AmerUs Board before the shareholder became an
interested shareholder, (b) upon consummation of the transaction which resulted
in the shareholder becoming an interested shareholder, the interested
shareholder owned at least eighty-five percent of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding, for
purposes of determining the number of shares outstanding, those shares owned by
persons who are directors and officers, and by employee stock plans in which
employee participants do not have rights to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange
offering; or (c) at or after the shareholder became an interested shareholder,
the business combination is approved by the AmerUs Board and approved at an
annual or special meeting of shareholders by two-thirds of the outstanding
voting stock of AmerUs which is not owned by the interested shareholder.
 
    The foregoing provisions of state law could have the effect of delaying,
deferring or preventing a change in control of AmerUs if the AmerUs Board
determines that a change of control is not in the best interests of AmerUs, its
shareholders and other constituencies. In addition, the regulatory restrictions
on the acquisition of securities of AmerUs may also deter attempts to effect, or
prevent the consummation of, a change in control of AmerUs.
 
    KANSAS BUSINESS COMBINATION ACT.  AmVestors is subject to Sections 17-12,100
et seq. of the KGCC, which imposes a three-year moratorium on business
combinations between a Kansas corporation and an Interested Stockholder. In
general, the KGCC prevents an Interested Stockholder from engaging in a Business
Combination with a Kansas corporation for three years following the date such
person became an Interested Stockholder. As used in the KGCC, the term "BUSINESS
COMBINATION" includes mergers or consolidations with an Interested Stockholder
and certain other transactions with an Interested Stockholder and certain other
transactions with an Interested Stockholder, including, without
limitation: (i) any sale, lease, exchange, mortgage, pledge, transfer or other
disposition to or with the Interested Stockholder of assets (except
proportionately as a stockholder of the corporation) having an aggregate market
value equal to 10% or more of the aggregate market value of all assets of the
corporation determined on a consolidated basis or the aggregate market value of
all the outstanding stock of the corporation; (ii) any transaction which results
in the issuance or transfer by the corporation or by certain subsidiaries
thereof of stock of the corporation or such subsidiary to the Interested
Stockholder, except pursuant to a transaction which, in general, effects a pro
rata distribution to all stockholders of the Corporation; (iii) any transaction
involving the corporation or certain subsidiaries thereof which has the effect,
directly or indirectly, of increasing the proportionate share of the shares of
any class or series, or securities convertible into shares of the corporation or
any subsidiary which is owned directly or indirectly by the Interested
Stockholders, or (iv) any receipt by the Interested Stockholders of the benefit
(except proportionately as a stockholder of the corporation) of any loans,
advances, guarantees, pledges, or other financial benefits provided by or
through the corporation or certain subsidiaries.
 
    The three-year moratorium may be avoided if: (i) before such person came an
Interested Stockholder, the board of directors approved either the Business
Combination or the transaction in which the Interested Stockholder became an
Interested Stockholder; or (ii) upon consummation of the transaction which
resulted in the stockholder becoming an Interested Stockholder, the stockholder
owned at least
 
                                       90
<PAGE>
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding shares held by directors who are also officers
of the corporation and by certain employee stock ownership plans); or (iii) on
or following the date on which such person became an Interested Stockholder, the
Business Combination is approved by the board of directors and authorized at an
annual or special meeting of stockholders by the affirmative vote of the
stockholders of at least 66 2/3% of the outstanding voting stock of the
corporation not owned by the Interested Stockholder.
 
    The Business Combination restrictions described above do not apply if, among
other things: (i) the corporation's original articles of incorporation contain a
provision expressly electing not to be governed by this provision; (ii) the
holders of a majority of the voting stock of the corporation approve an
amendment to its articles of incorporation or by-laws expressly electing not to
be governed by this provision (effective twelve (12) months after the
amendment's adoption), which amendment shall not be applicable to any Business
Combination with a person who was an Interested Stockholder at or prior to the
time of the amendment; or (iii) the corporation does not have a class of voting
stock that is (a) listed on a national securities exchange, (b) authorized for
quotation on Nasdaq or a similar quotation system; or (c) held of record by more
than 2,000 stockholders.
 
    This provision of the KGCC also does not apply to certain Business
Combinations with an Interested Stockholder when such combination is proposed
after the public announcement of, and before the consummation or abandonment of,
a merger or consolidation, a sale of 50% or more of the aggregate market value
of the assets of the corporation on a consolidated basis or the aggregate market
value of all outstanding shares of the corporation, or a tender offer for 50% or
more of the outstanding voting shares of the corporation, if the triggering
transaction is with or by a person who either was not an Interested Stockholder
with board of director approval, and if the transaction is approved or not
opposed by a majority of the current directors who were also directors prior to
any person becoming an Interested Stockholder during the previous three years.
The AmVestors Charter does not contain a provision expressly electing not to be
covered by the Business Combinations restrictions of the KGCC, so such
restrictions apply to AmVestors.

    The following chart illustrates the general organization of AmerUs
immediately following completion of the Merger, assuming the Merger
Consideration is 0.6724 shares of AmerUs Class A Common Stock and all warrants
and options to purchase AmVestors Common Stock are rolled over into warrants and
options to purchase shares of AmerUs Class A Common Stock. The percentages shown
do not include shares of AmerUs Class A Common Stock which may be issued upon
exercise of warrants and options following the Merger. In addition, the
percentage of AmerUs Common Stock owned by AmerUs Group would be increased if,
as expected, AmerUs Group acquires additional shares of AmVestors Common Stock
prior to completion of the Merger.
 
    AmerUs has two classes of common stock. In the Merger, AmVestor stockholders
would receive AmerUs Class A common stock, the same class held by other public
shareholders. AMHC beneficially owns all outstanding shares of AmerUs Class B
common stock. Under the AmerUs Charter, shares of AmerUs Class B common stock
carry with them the right to cast a number of votes generally intended to ensure
that AMHC has the right to cast at least 50.1% of the votes entitled to be cast
with respect to capital stock of AmerUs. See "DESCRIPTION OF AMERUS CAPITAL
STOCK." See "ADDITIONAL INFORMATION REGARDING AMERUS--Business--Certain
Transactions and Relationships" for information concerning the relationship

                    ADDITIONAL INFORMATION REGARDING AMERUS
 
BUSINESS
 
    GENERAL.  AmerUs is a holding company engaged through its subsidiaries in
the business of marketing, underwriting and distributing a broad range of
individual life insurance and annuity products to individuals and businesses in
49 states and the District of Columbia. AmerUs' primary product offerings
consist of whole life, universal life and term life insurance policies and fixed
annuities. In addition, through a joint venture arrangement (the "AMERITAS JOINT
Venture"), AmerUs Life's distribution systems market fixed annuities issued by
AVLIC and sell AVLIC's variable life insurance and variable annuity products.
Based on published comparisons and rankings of life insurance and annuity
products, AmerUs believes that its products have a long history of being
competitive within the industry.
 
    AmerUs was formed in 1996 in connection with the creation of AMHC, the first
mutual insurance holding company in the United States. AMHC owns 100% of AmerUs
Group, AmerUs' controlling shareholder. AmerUs' subsidiary, AmerUs Life, was
originally incorporated in 1896 as a mutual insurance company under the name
Central Life Assurance Society of the United States. Its name was changed to
American Mutual Life Insurance Company in 1994 following the merger of Old AML
into Central Life. On June 30, 1996, American Mutual Life Insurance Company was
converted into a stock life insurance company pursuant to the AmerUs
Reorganization Plan (as defined below) and its name was changed to AmerUs Life
Insurance Company. As of June 30, 1997, AmerUs Life had approximately 424,000
life insurance policies and annuity contracts outstanding and individual life
insurance in force, net of reinsurance, of approximately $25.9 billion. As of
June 30, 1997, AmerUs had total assets of $4.5 billion and total shareholders'
equity of $535 million. On February 3, 1997, AmerUs received $56.7 million in
gross proceeds from a subscription offering and initial public offering of
shares of its AmerUs Class A Common Stock.
 
    On October 23, 1997 AmerUs acquired Delta. Delta specializes in the sale of
individual single and flexible premium deferred annuities, primarily in the
southeastern, western, southwestern and midwestern regions of the United States.
Sales are made primarily through a network of over 3,400 independent agents.
Delta's strategy is to target the conservative saver by offering conservative
asset management and an innovative product design. Approximately 55% of Delta's
1996 direct collected premiums were derived from retirement-oriented
tax-qualified annuities. Delta Life is licensed in the District of Columbia and
in all states except New York. For a discussion of the business, products and
distribution systems of Delta, see "--Recent Developments--Acquisition of Delta
Life Corporation."
 
    AmerUs' target markets are individuals in the middle and upper income
brackets and small businesses. Its geographic focus is national in scope (except
for New York, in which AmerUs is not licensed to do business), and it primarily
serves suburban and rural areas. AmerUs Life distributes its products primarily
through a combination of career general agency and personal producing general
agency ("PPGA") distribution systems, as well as a network of independent
brokers. The career general agency system consists of a network of 36 career
general agencies, with approximately 540 career agents. The PPGA system is
comprised of approximately 450 PPGAs, with approximately 1,050 agents. Variable
life insurance products and the fixed and variable annuities offered by the
Ameritas Joint Venture are marketed through AmerUs Life's distribution systems
and the distribution systems of Ameritas and AVLIC, which consist of
approximately 200 agents and 450 independent broker-dealers (with approximately
8,300 registered representatives), respectively.
 
    The pricing of AmerUs' products is generally determined by reference to
actuarial calculations and statistical assumptions principally relating to
mortality, persistency, investment yield assumptions, estimates of expenses and
management's judgment as to market and competitive conditions. The premiums and
deposits received, together with assumed investment earnings, are designed to
cover policy benefits, expenses and policyowner dividends plus return a profit
to AmerUs. These profits arise from the margin between mortality charges and
insurance benefits paid, the margin between actual investment results and the
investment income credited to policies (either directly or through dividends to
 
                                      102
<PAGE>
policyowners) and the margin between expense charges and actual expenses. The
level of profits also depends on persistency because business acquisition costs,
particularly agent commissions, are recovered over the life of the policy.
Dividends and interest credited on policies (including policies included in the
Closed Block) may vary from time to time reflecting changes in investment,
mortality, persistency, expenses and other factors. Interest rate fluctuations
have an effect on investment income and may have an impact on policyowner
behavior. Increased lapses in policies may be experienced if AmerUs does not
maintain interest rates and dividend scales that are competitive with other
products in the marketplace.
 
    BUSINESS STRATEGY.  AmerUs' business strategy to achieve earnings growth and
increase share-holder value is focused on managing certain operating
fundamentals where AmerUs' results have historically compared favorably to the
industry. AmerUs intends to utilize these operating strengths to differentiate
its products by maintaining its position and reputation as a low-cost producer
that provides high-value products to its life insurance and annuity customers,
while also providing superior service to both agents and customers. AmerUs
believes it is well positioned to compete effectively based upon a number of
strengths including its strong operating performance, customer-driven product
offerings, productive and diversified distribution systems, sophisticated
asset/liability management capabilities and a customer service orientation. In
addition, AmerUs may continue to seek new business opportunities through
mergers, acquisitions and strategic alliances.
 
    THE AMERUS REORGANIZATION.
 
    Description of the AmerUs Reorganization.  On October 27, 1995, the Board of
Directors of American Mutual Life adopted the plan of reorganization (the
"AMERUS REORGANIZATION PLAN"), pursuant to which AMHC was formed as a mutual
insurance holding company and American Mutual Life was converted into a stock
life insurance company and its name was changed to AmerUs Life Insurance
Company.
 
    As part of the AmerUs Reorganization, all of the shares of capital stock of
AmerUs Life were issued to AMHC. Subsequently, AMHC contributed all of its
shares of capital stock of AmerUs Life to AmerUs Group, which contributed such
shares to AmerUs, AmerUs Group's then wholly-owned subsidiary. Under this
structure, AmerUs is an intermediate holding company, with AmerUs Group as its
direct controlling shareholder and AmerUs Life as its wholly-owned subsidiary.
Under Iowa law, AMHC is required to retain direct or indirect ownership and
control of shares which carry the right to cast a majority of the votes entitled
to be cast by holders of the outstanding capital stock of AmerUs Life.
 
    American Mutual Life was the first company to obtain approval under the Iowa
mutual holding company statute to form a mutual insurance holding company.
AmerUs understands that the states of California, Florida, Kansas, Louisiana,
Minnesota, Missouri, Nebraska, North Dakota, Ohio, Oregon, Pennsylvania, Rhode
Island, Texas and Vermont, and the District of Columbia, have adopted laws
authorizing the formation of mutual insurance holding companies.
 
    Background and Reasons for the AmerUs Reorganization.  Recognizing the
capital-raising difficulties faced by mutual insurers and the present
competitive state of the insurance industry, the Iowa legislature in 1995
amended Iowa's insurance law to permit mutual insurance companies incorporated
in Iowa to reorganize into a mutual insurance holding company structure.
 
    As a mutual life insurance company, American Mutual Life had no ability to
issue shares of capital stock and consequently had no access to market sources
of equity capital and limited ability to increase its surplus and fund future
growth while maintaining the financial strength necessary to assure policyowners
that their obligations will be met. The AmerUs Reorganization positioned AmerUs
to obtain access to equity capital by effecting equity offerings as necessary
and appropriate to satisfy its capital requirements.
 
    The AmerUs Reorganization was also intended to facilitate potential mergers,
acquisitions and strategic alliances by creating a more flexible corporate
structure. Among other things, the AmerUs Reorganization positioned AmerUs to
issue stock to consummate acquisitions.
 
                                      103
<PAGE>
    The Iowa legislation permits AMHC to demutualize, a process which would
cause AMHC to convert from mutual to stock form and become publicly owned by
shareholders. Pursuant to AmerUs' Charter, upon a demutualization all of AmerUs'
shares of outstanding AmerUs Class B Common Stock will automatically convert
into shares of AmerUs Class A Common Stock. See "DESCRIPTION OF AMERUS CAPITAL
STOCK." AMHC has advised AmerUs that AMHC has no present plans to demutualize.
 
    Establishment and Operation of the Closed Block.  In connection with the
AmerUs Reorganization, the Closed Block was established. Insurance policies
which had a dividend scale in effect as of June 30, 1996 were included in the
Closed Block. The Closed Block was designed to provide reasonable assurance to
policyowners included therein that, after the AmerUs Reorganization, assets will
be available to maintain the dividend scales and interest credits in effect
prior to the AmerUs Reorganization if the experience underlying such scales and
credits continues. The establishment of the Closed Block did not alter,
diminish, reduce or in any other way adversely affect these policyowners'
contractual rights.
 
    The Closed Block was established on June 30, 1996. Pursuant to the AmerUs
Reorganization Plan, assets were allocated to the Closed Block at June 30, 1996
in an amount which AmerUs expects to produce cash flows which, together with
anticipated revenues from the Closed Block Business, are expected to be
sufficient to support the Closed Block Business, including provision for payment
of claims, taxes and certain other expenses and for the continuation of dividend
scales and interest credits in effect prior to the Amerus Reorganization if the
experience underlying such scales and credits continues or for appropriate
adjustments in such scales and credits if the experience changes. The assets,
including the revenue therefrom, allocated to the Closed Block will accrue
solely to the benefit of policyowners included in the Closed Block Business
until such time as the Closed Block is no longer in effect. To the extent that
over time cash flows from the assets allocated to the Closed Block and other
experience relating to the Closed Block are, in the aggregate, more or less
favorable than assumed in establishing the Closed Block, total dividends and
interest credits paid to Closed Block policyowners in the future may be greater
than or less than the total dividends and interest credits that would have been
paid to these policyowners if the dividend scales and interest credits in effect
prior to the AmerUs Reorganization had been continued. Dividends and interest
credits on policies included in the Closed Block, as in the past, will be
declared at the discretion of AmerUs Life's Board of Directors and may vary from
time to time (reflecting changes in investment, mortality, persistency and other
experience factors). AmerUs Life will not be required to support the payment of
dividends and interest credits on Closed Block policies from its general funds
above certain guaranteed levels, although it could choose to provide such
support if it were deemed to be in the best interests of AmerUs Life's
shareholders.
 
    AmerUs Life will continue to pay guaranteed benefits under all policies,
including the policies included in the Closed Block, in accordance with their
terms. If the assets allocated to the Closed Block, the investment cash flows
from those assets and the revenues from the policies included in the Closed
Block including investment income thereon prove to be insufficient to pay the
benefits guaranteed under the policies included in the Closed Block, AmerUs Life
will be required to make such payments from its general funds. AmerUs Life bears
the costs of operating and managing the Closed Block and, accordingly, such
costs were not funded as part of the assets allocated to the Closed Block. Any
increase in such costs in the future would be borne by AmerUs Life. Since the
Closed Block has been funded to provide for payment of guaranteed benefits as
well as future dividends, it should not be necessary to use other general funds
to pay guaranteed benefits unless the Closed Block Business experiences
substantial adverse deviations in investment, mortality, persistency or other
experience factors. While AmerUs Life will use its best efforts to support the
policies included in the Closed Block with the assets allocated to the Closed
Block, these assets will be subject to the same liabilities (with the same
priority in liquidation) as assets outside the Closed Block.
 
    The Closed Block will continue in effect until either (i) the last policy in
the Closed Block is no longer in force or (ii) the Closed Block is dissolved.
The AmerUs Reorganization Plan provides that the Closed Block may not be
dissolved without the approval of the Iowa Commissioner, which approval could
only be obtained if dissolution were demonstrated not to be adverse to the
interests of the policyowners whose policies make up the Closed Block. If the
Closed Block is dissolved, the assets associated with
 
                                      104
<PAGE>
the Closed Block will become part of AmerUs Life's general funds. If the Closed
Block is not dissolved, the expected life of the Closed Block is in excess of 75
years.
 
    Closed Block Assets and Liabilities.  At June 30, 1997, the Closed Block had
assets of $1,307.4 million and liabilities of $1,563.8 million. The excess of
Closed Block Liabilities over Closed Block Assets represents the expected future
after-tax contributions (before certain other expense charges, which were not
funded in the Closed Block) from the Closed Block which may be recognized in
income over the period the policies in the Closed Block remain in force.
 
    If the actual contribution from the Closed Block in any given period equals
or exceeds the expected contribution for such period as determined at the
establishment of the Closed Block, only the expected contribution would be
recognized in income from continuing operations for that period. Any excess of
the actual contribution over the expected contribution is recognized in income
from continuing operations to the extent that the aggregate expected
contribution for all prior periods exceeded the aggregate actual contribution.
Any remaining excess of actual contribution over expected contributions would be
accrued in the Closed Block as a liability for future policyowners' dividends.
This accrual for future dividends effectively limits the actual Closed Block
contribution recognized in income from continuing operations to the Closed Block
contribution expected to emerge from operation of the Closed Block as determined
as of the date of establishment of the Closed Block.
 
    If the actual contribution from the Closed Block in any given period is less
than the expected contribution for that period, because changes in dividends
scales are inadequate to offset the negative performance in relation to the
expected performance, the contribution inuring to shareholders of AmerUs Life
will be reduced. If a liability for policyowners' dividends had been previously
established in the Closed Block because the actual contribution to the relevant
date had exceeded the expected contribution to such date, such liability would
be reduced (but not below zero) in any periods in which the actual contribution
for that period is less than the expected contribution for such period.
 
    AMERITAS JOINT VENTURE.  Ameritas Life Insurance Corp. ("AMERITAS") is a
Nebraska mutual life insurance company which has been in existence for more than
100 years. Ameritas is licensed to conduct business in the District of Columbia
and in all states except New York, and had approximately 200 agents as of June
30, 1997. On a statutory basis, Ameritas had $1.8 billion in assets, $8.1
billion of insurance in force and $285.2 million in policyowners' surplus as of
June 30, 1997. Ameritas currently is rated "AA" (Excellent) by Standard & Poor's
and "A+" (Superior) by A.M. Best.
 
    AmerUs participates in the Ameritas Joint Venture through AmerUs Life's 34%
ownership interest in AMAL Corporation, a Nebraska corporation ("AMAL"). AMAL's
operations are conducted through AVLIC and Ameritas Investment Corp., a
registered broker-dealer ("AIC"), its two wholly-owned subsidiaries, which have
been in business since 1983. AVLIC is licensed to conduct business in 46 states
and the District of Columbia and currently markets its products and those of AIC
through approximately 450 independent broker-dealers (with approximately 8,300
registered representatives) and the Ameritas distribution system. AIC is a
registered broker/dealer which is licensed to do business in 49 states. As of
June 30, 1997, AMAL had total consolidated assets of $1,324.7 million and total
consolidated stockholders' equity of $68.0 million on a GAAP basis. AVLIC had
$3.4 billion of insurance in force and $44.8 million in surplus as of June 30,
1997, on a statutory basis.
 
    AmerUs Life contributed $20.4 million in cash and substantially all of its
new fixed annuity production, as well as other consideration, for its interest
in AMAL. Under the terms of the Joint Venture Agreement, AmerUs Life has an
option to purchase an additional 5% to 15% of AMAL (the "OPTION") if certain
premium growth targets are met. The AMAL Option is exercisable in three
portions, each of which would permit AmerUs Life to acquire the number of
newly-authorized shares that would increase its equity ownership by 5%. Each
portion of the AMAL Option is exercisable at specified exercise prices set forth
in the Joint Venture Agreement.
 
    Management of the Ameritas Joint Venture is shared between AmerUs Life and
Ameritas. Each has equal membership on the board of directors of AMAL, AVLIC and
AIC.
 
                                      105
<PAGE>
    The Joint Venture Agreement provides that certain conditions may trigger
buy-sell provisions of the Joint Venture Agreement in the event of certain
disputes between the parties. For example, if at any time during the
continuation of the Ameritas Joint Venture a dispute arises between the parties,
the Joint Venture Agreement sets forth a mechanism for the resolution of the
dispute by informal means, including mediation. In certain specified
circumstances, in the event a major dispute remains unresolved, certain buy-sell
provisions of the Joint Venture Agreement can be triggered. Further, each party
may make and/ or enter into acquisitions, divestitures, mergers, consolidations,
or other transactions affecting its corporate structure. However, if any such
transaction involves or constitutes a "change of control" with respect to
Ameritas or AmerUs Life, then the other party shall have the right to trigger
the buy-sell provisions of the Joint Venture Agreement. A "change of control" is
deemed to have occurred if a majority of the board of directors of an entity or
an ultimate parent shall consist of individuals who were not directors of such
entity prior to such transaction or who were not nominated for board membership
by such directors.
 
    AmerUs and Ameritas each have guaranteed the obligations of AVLIC. The
guarantee of each party is joint and several, and will remain in effect until
certain financial conditions are met.
 
    PRODUCTS.  AmerUs offers a diverse line of individual life insurance
products which are tailored to its markets and distributed primarily through its
career general agency and PPGA distribution systems. In addition, AmerUs
recently acquired Delta, through which it now offers additional annuity products
through an extensive network of independent agents. AmerUs also is a party to
the Ameritas Joint Venture, which offers fixed and variable annuity and variable
life insurance products. As a result of superior operating fundamentals,
including mortality, persistency, operating expenses and investment yield,
AmerUs has had a long history of providing high-value, low-cost products to its
customers, while operating profitably. Moreover, AmerUs continuously reviews and
updates its product portfolio in order to continue offering a broad range of
products at competitive performance levels.
 
    Individual Life Insurance and Fixed Annuity Products of AmerUs
Life.  Traditional life insurance has accounted for approximately 70% of AmerUs
Life's total individual life insurance premiums for the last three years and
universal life insurance has accounted for approximately 30% of its total
individual life insurance premiums for the same time period. In addition, AmerUs
Life has historically offered a broad line of fixed annuity products.

    Traditional Life Insurance Products.  AmerUs Life's traditional life
insurance products have a long history of being highly competitive within the
industry. AmerUs Life is the only participant in the industry to have had its
participating whole life insurance products ranked among the top ten in annual
surveys prepared by A.M. Best for each of the years 1976 through 1995. AmerUs
Life ranked 14th and 10th for the 10- and 20-year measures, respectively, for
1996, and ranked 12th and 9th for the 10- and 20-year measures, respectively,
for 1997. (Source: Best's Review, Rankings of 10- and 20-year Interest Adjusted
Surrender Cost Index, 1976-1997). Management believes that such surveys provide
a gauge for measuring product performance based upon operating fundamentals,
including mortality, persistency, operating expenses and investment yield, and
that the consistent high rankings of AmerUs Life's traditional life insurance
products in such surveys reflect AmerUs Life's status within the industry as a
provider of high-value products to its customers.
 
    AmerUs Life's traditional life insurance products include participating
whole life and term life insurance products. Participating whole life insurance
is designed to provide benefits for the life of the insured. This product
generally provides for level premiums and a level death benefit and requires
payments in excess of the mortality cost in earlier years to offset increasing
mortality costs in later years. AmerUs Life also offers a second to die whole
life insurance product which insures two lives and provides benefits upon the
death of the second insured. AmerUs Life targets its second to die products
primarily to potential customers seeking to achieve estate planning goals.
 
    AmerUs Life also offers a portfolio of term life insurance policies that
provide life insurance protection for a specific time period (which generally
can be renewed at an increased premium). Such policies are mortality-based and
offer no cash accumulation feature.
 
    Since 1989, AmerUs Life has offered a flexible life insurance product, which
is a combination of permanent participating whole life insurance, increasing
paid-up additions and decreasing term insurance coverage. In 1994, AmerUs Life
began offering an enhanced version of this product. These products give
policyowners additional flexibility in designing an appropriate combination of
permanent and term life insurance coverages to meet their specific needs at
varying premium levels.
 
    For the six months ended June 30, 1997, sales of participating whole life
and term life insurance products represented 61% and 13%, respectively, of first
year annualized premiums for all individual life insurance products.
 
    Universal Life Insurance Products.  AmerUs Life offers universal life
insurance products, pursuant to which an insurance account is maintained for
each insurance policy. Premiums, net of specified expenses, are credited to the
account, as is interest, generally at a rate determined from time to time by
AmerUs Life. Specific charges are made against the account for the cost of
insurance protection and for AmerUs Life's expenses. The universal life form
allows for flexibility as to the amount and timing of premium payments and for
the level of death benefits provided.
 
    AmerUs Life has maintained consistently competitive universal life products.
Based on annual surveys by A.M. Best measuring account and cash values of
universal life products, AmerUs Life's products have consistently ranked in the
top half of all companies included in the survey with respect to account values
and has ranked in the top quarter of all companies included in the survey with
respect to cash values. (Source: Best's Review, Rankings of 5-year Account and
Cash Values, 1991-1997; Rankings of 10-year Account and Cash Values, 1993-1997,
with 1993 the initial year of the survey of 10-year values).
 
    AmerUs Life's universal life insurance products provide benefits for the
life of the insured. Within limits established by AmerUs Life and state
regulations, policyowners may vary the premiums and the amount of the policy's
death benefit as long as there are sufficient policy funds available to cover
all policy charges for the coming period. Interest is credited to the policy at
a rate determined from time to time by AmerUs Life. The weighted average
crediting rate for AmerUs Life's universal life insurance liabilities was 6.27%
for the year ended December 31, 1996 and 6.24% for the six months ended June 30,
 
                                      107
<PAGE>
1997. For the six months ended June 30, 1997, sales of universal life insurance
products represented 26% of first year annualized premiums for all individual
life insurance products.
 
    Fixed Annuity Products.  Historically, AmerUs Life has offered a broad
portfolio of fixed annuity products. Annuities provide for the payment of
periodic benefits for a specified time period. Benefits may commence immediately
or may be deferred to a future date. Fixed annuities generally are backed by a
general investment account and credited with a rate of return that is
periodically reset.
 
    AmerUs Life's fixed annuity products are also highly competitive within the
industry. AmerUs Life's single premium deferred annuity products were ranked
among the industry leaders in annual surveys by A.M. Best for 1991 through 1996
measuring account and cash values of single premium deferred annuity products of
participants in the industry. (Source: Best's Review, Rankings of 5- and 10-year
Account Values and 5- and 10-year Cash Values, 1991-1996).
 
    From September 1993 until the commencement of the Ameritas Joint Venture in
1996, the majority of AmerUs Life's fixed annuity sales consisted of its
Advantage Series of deferred annuities. The Advantage Series consists of three
products comprised of two book value annuities, which are fixed annuities, and
one market value adjusted annuity, which is a fixed annuity with a market
adjustment feature. Both book value annuities have a first year interest rate
guarantee. One of the book value annuities also provides a bonus interest rate
for the first year. The market value adjusted annuity has a first year interest
rate guarantee and also provides a bonus interest rate for the first year. In
1996, the Advantage Series accounted for over $59 million in premiums, which
represented approximately 82% of AmerUs Life's total fixed annuity production
for the year.
 
    Delta Products.  Delta Life specializes in the sale of individual life and
flexible premium deferred annuities. Delta Life also markets two single premium
equity index annuity products that are based either on the S&P
500-Registered Trademark- or an international index created by Delta Life from
stock market indexes from France, Germany, Japan, Switzerland and the United
Kingdom. See "--Recent Developments--Acquisition Of Delta Life
Corporation--Products."
 
    Ameritas Joint Venture Products.  On April 1, 1996, AmerUs commenced the
Ameritas Joint Venture with Ameritas, through which AmerUs Life's distribution
systems offer AVLIC's fixed annuity products and AVLIC's variable life insurance
and annuity products. The fixed annuities currently offered by the Ameritas
Joint Venture are substantially similar to AmerUs' Advantage Series products.
AmerUs' investment in the Ameritas Joint Venture affords AmerUs access to a line
of existing variable life insurance and variable annuity products while
providing a lower-cost entry into an established business, thereby eliminating
significant start-up costs and allowing for immediate potential earnings. See
"-- Ameritas Joint Venture."
 
    The Ameritas Joint Venture offers, through AVLIC, flexible premium and
single premium variable universal life insurance products and variable
annuities. Variable products provide for allocation of funds to a general
account or to one or more separate accounts under which the owner bears the
investment risk. Through AVLIC's fund managers, which include Fidelity
Management and Research Company, Fred Alger Management, Inc. and Massachusetts
Financial Services Company, owners of variable annuities and life insurance
policies are able to choose from a range of investment funds offered by each
manager. In the future, AVLIC may also sell low load life insurance products,
which have a lower commission rate, and may acquire other companies or business
lines in appropriate circumstances.
 
    Under the terms of the Joint Venture Agreement governing the Ameritas Joint
Venture, AmerUs and Ameritas will write a substantial portion of their new
single and flexible premium deferred fixed annuities and variable annuities and
variable life insurance through the Ameritas Joint Venture. AmerUs has retained
the right to continue to issue replacement business to its fixed annuity
customers in existence prior to the effective date of the Joint Venture
Agreement.
 
    The variable life insurance products and the fixed and variable annuities
offered by the Ameritas Joint Venture are distributed through AmerUs' career
general agency and PPGA distribution systems, as
 
                                      108
<PAGE>
well as through the distribution systems of Ameritas and AVLIC. See "--Ameritas
Joint Venture" and "--Certain Transactions and Relationships."
 
    In response to customer demand, AmerUs Life developed an equity index
annuity which it began offering through the Ameritas Joint Venture in the fourth
quarter of 1996. AmerUs Life retained the right to issue this type of contract
to its customers in existence prior to the effective date of the Joint Venture
Agreement and through certain other distribution systems. An equity index
annuity provides a guaranteed cash value independent of the equity markets. In
addition, the credited rate is linked to an external equity index, such as the
S&P 500-Registered Trademark- stock index excluding dividends.
 
    Sponsored Products.  AmerUs also derives fee income from the sale of various
sponsored products through its career general agency and PPGA distribution
systems under co-marketing arrangements with leading insurance providers for
such products. Such sponsored products include individual long-term disability
and group life, health and dental insurance products.

(A) Effective May 1996, substantially all new sales of individual deferred
    annuities are made through the Ameritas Joint Venture, which sales are not
    reflected in the above table. See "--Ameritas Joint Venture."
 
(B) AmerUs Life sold substantially all of its group life business as of July 1,
    1996 and is no longer actively marketing this line of business.
 
    AmerUs Life's traditional life insurance products include participating
whole life and term life insurance products. The reduction in the number of
traditional life insurance policies reflected in the above table is attributable
to policy surrenders, policy terminations or expirations, and consolidations of
one or more outstanding policies into new policies. While AmerUs Life has
experienced a decrease in the number of traditional life policies, the size of
the policies outstanding has increased and the amount of premiums collected has
also increased. For universal life products, AmerUs Life has experienced a
reduction in both the number of policies and face amounts in force. Such
reductions in universal life policies in force are attributable to similar
termination activities as with the traditional life products. For universal life
products, AmerUs Life has not experienced growth in the average policy size in
force in recent years as significant as has been experienced for traditional
life due to the more recent introduction in the 1980's of universal life
policies. Therefore, the reduction in number of policies has resulted in a
reduction in the amount of insurance in force. The reduction in the amount of
annuity business in force is primarily attributable to the transfer of new
annuity production to the Ameritas Joint Venture in May 1996. AmerUs' investment
in the Ameritas Joint Venture is carried on the equity method of accounting.
 
    AmerUs Life has experienced higher persistency for its life insurance
products (i.e., lower lapse rates) than industry averages. Persistency is
measured in terms of renewal premiums. While AmerUs Life has generally
experienced a decrease in the number of policies outstanding over the last
several years, the size of policies outstanding has increased and the amount of
premiums collected has increased.
 
                                      110
<PAGE>
Such increased premium levels are in large part due to AmerUs Life's favorable
persistency. The ability to achieve higher persistency also results in lower
unit costs. The following table illustrates lapse rates on individual life
insurance products for AmerUs Life and for stock and mutual life insurance
companies for the years ended December 31, 1992 through 1996:

    DISTRIBUTION.  AmerUs Life markets its insurance products on a national
basis primarily through a career general agency system, a PPGA system,
independent insurance brokers and certain of AmerUs' affiliates. AmerUs Life
employs nine regional vice presidents who are responsible for supervising the
career general agencies and/or PPGA agents within their assigned geographic
regions.

(A) Effective May 1996, substantially all new sales of individual deferred
    annuities are made through the Ameritas Joint Venture. See "--Ameritas Joint
    Venture."
 
    Career General Agency System and Brokers.  Under the career general agency
system, AmerUs Life enters into a contractual arrangement with the career
general agent for the sale of insurance products by the career agents and
brokers assigned to the career general agent's agency. The career general agents
are primarily compensated by receiving a percentage of the first year
commissions paid to career agents and brokers in the career general agent's
agency and by renewal commissions on premiums subsequently collected on that
business.
 
    The career general agents are independent contractors and are generally
responsible for the expenses of operating their agencies, including office and
overhead expenses and the recruiting, selection, contracting, training and
development of career agents and brokers in their agency. Currently, AmerUs Life
has 36 career general agencies in 24 states, through which approximately 540
career agents sell AmerUs Life's products. While career agents in the career
general agency system are non-exclusive, AmerUs Life believes most agents use
AmerUs Life's products for a majority of their new business of the type of
products offered by AmerUs Life. No single career general agency accounts for
more than 10% of the total first year commissions paid by AmerUs Life.
 
    Career agents are also independent contractors and are primarily compensated
by commissions on first year and renewal premiums collected on business written
by them. In addition, career agents can earn bonus commissions, graded by
production and persistency on their business.
 
    AmerUs Life believes the quality of the agents in its career general agency
system is competitive with that of other life insurance companies. AmerUs Life's
retention of its career general agency sales force has historically been above
the average retention rates of other companies in the industry. AmerUs
 
                                      112
<PAGE>
Life attributes its success in attracting and retaining qualified agents to the
high quality of its products, its marketing support and administrative services
and its competitive compensation structure. AmerUs Life also provides career
general agents with various screening tools which enable the general agents to
screen career agent applicants to eliminate those who may not be qualified.
 
    AmerUs Life also sells its products through a network of approximately 1,750
insurance brokers in all jurisdictions in which AmerUs Life is licensed to sell
insurance. Brokers are independent contractors who sell a variety of insurance
products issued by various companies. Brokers operate through the career general
agency system but are compensated under a commission structure which is separate
from those used for career agents and in the PPGA system.
 
    Personal Producing General Agency System.  Under the PPGA system, AmerUs
Life contracts primarily with individuals who are experienced individual agents
or head a small group of experienced individual agents. These individuals are
independent contractors and are responsible for all of their own expenses. These
individuals often sell products for other insurance companies, and may offer
selected products of AmerUs Life rather than AmerUs Life's full line of
insurance products.
 
    PPGAs are compensated by commissions on first year and renewal premiums
collected on business written by themselves and the agents in their units. In
addition to a base commission, PPGAs may earn bonus commissions on their
business, graded by production and persistency.
 
    Distributions Through Affiliates.  AmerUs Life also sells its products
through certain of its affiliated companies. AmerUs Life has arrangements with
AmerUs Investments, Inc. ("AmerUs Investments"), a wholly-owned subsidiary of
AmerUs Bank, to market products of AmerUs Life. AmerUs Life has entered into an
agreement with AmerUs Investments pursuant to which AmerUs Life and AVLIC pay
AmerUs Investments fees in the form of commissions in exchange for generating
sales of such products. Persons selling AmerUs Life's products under this
arrangement are employees of AmerUs Investments and are paid a regular salary in
addition to being eligible for commissions under a commission structure (which
is distinct from the structure used under AmerUs Life's career general agency
and PPGA systems). See "--Agreements Involving Real Estate--Sale of Insurance
Policies."
 
    AVLIC has a separate arrangement with AmerUs Investments pursuant to which
AmerUs Investments sells variable and fixed annuities and variable life
insurance products.
 
    Marketing Support Services.  AmerUs Life also supports its distribution
systems with a trained staff of marketing and other professionals who provide
the career general agency and PPGA systems with a wide range of services in
support of the sale of AmerUs Life's products. In addition to providing
information about the products offered by AmerUs Life, these professionals are
able to offer detailed advice on business insurance, financial and estate
planning and other advanced underwriting services.
 
    AmerUs Life also provides its agents in both the career general agency and
PPGA systems with insurance industry information support services and computer
technology. For example, an advanced illustration and sales presentation
computer software package is provided to agents to assist them in their selling
efforts. In addition, AmerUs Life's agents use computer technology to
individualize marketing and product use information at the point of sale to
better service policyowners and potential policyowners. AmerUs Life supports
these systems with in-house computer professionals to assist agents with
software and systems questions relating to its computer-assisted marketing
tools.
 
    AmerUs Life conducts an intensive annual educational conference as part of
its continuing efforts to educate and train agents and to market AmerUs Life's
products. The conference is generally well-attended by AmerUs Life's agents and
other interested persons who are not affiliated with AmerUs Life.
 
    Distribution System of Delta.  Delta Life's annuity products are sold
through independent agents who are supervised by regional directors with
specified geographic supervisory responsibilities. The regional directors are
primarily responsible for recruiting agents and servicing those agents in an
effort to promote Delta Life's products. The regional directors' marketing
support activities include informational mailings, seminars, and case
consultations all of which are designed to educate agents about
 
                                      113
<PAGE>
annuities in general and Delta Life in particular. Regional directors are paid
an override commission on the business produced by agents within their
territory. There are currently nine regional directors covering the
southeastern, western, southwestern and midwestern regions of the United States.
 
    The regional directors are responsible for the over 3,400 licensed,
independent agents, who may also sell insurance products of other companies. Of
these agents, approximately 900 have written new business for Delta Life for the
first six months of 1997. No single agent was responsible for more than 1.2% of
Delta Life's 1996 annuity premiums. No significant amount of business is
produced by stock brokerage firms, banks or large national insurance brokerage
agencies.
 
    INSURANCE UNDERWRITING.  AmerUs Life follows detailed, uniform underwriting
practices and procedures in its insurance business which are designed to assess
risks before issuing coverage to qualified applicants. AmerUs Life has
professional underwriters who evaluate policy applications on the basis of
information provided by applicants and others. As demonstrated by the following
table, AmerUs Life's underwriting standards produced mortality results which are
generally more favorable than the assumptions used in its product pricing, which
are based upon industry guidelines:

(A) Results illustrated for 1992-1993 are for Central Life only. The 1992-1993
    results for Old AML are unavailable. Management believes that the 1992-1993
    mortality experience for Old AML would not materially change the statistics
    reported for 1992-1993.
 
(B) Pricing mortality is established at a level below the 1975-1980 Basic Table,
    an experience mortality table widely used in the industry as a basis of
    mortality.
 
    Management also believes that its actual mortality results compare favorably
to those of others in the industry. AmerUs Life believes that its favorable
mortality results are attributable to, among other things, the geographic
location of its customer base in rural and suburban areas (as opposed to urban
areas), the higher-income profile of its customer base and its consistent
application of appropriate underwriting criteria to the processing of new
customer applications. Actual incurred mortality for 1996 was very favorable
compared to pricing, but is not necessarily indicative of future mortality
results.
 
    RESERVES.  In accordance with applicable insurance regulations, AmerUs
records as liabilities in its statutory financial statements actuarially
determined reserves that are calculated to meet future obligations of AmerUs' in
force life insurance and annuity contracts. The reserves are based on
actuarially recognized methods using prescribed morbidity and mortality tables
and interest rates. Reserves include unearned premiums, premium deposits, claims
that have been reported but are not yet paid, claims that have been incurred but
have not been reported, and claims in the process of settlement. AmerUs'
reserves comply with state insurance department statutory requirements.
 
    The liability for future policy benefits reflected in the AmerUs
Consolidated Financial Statements for traditional life insurance is computed
using a net level method, utilizing the guaranteed interest and mortality rates
used in calculating cash surrender values as described in the contracts. Benefit
reserves for traditional limited-payment life insurance policies include the
deferred portion of the premiums received during the premium-paying period.
Deferred premiums are recognized as income over the life of the policies. Policy
benefit claims are charged to expense in the period that the claims are
incurred. All insurance-related benefits, losses and expenses are reported net
of reinsurance.
 
    Future policy benefit reserves for universal life insurance and investment
products are computed under a retrospective deposit method and represent policy
account balances before applicable surrender charges. Policy benefits and claims
that are charged to expense include benefit claims incurred in the period in
excess of related policy account balances.

    REINSURANCE.  In accordance with industry practices, AmerUs reinsures
portions of its life insurance and disability income exposure, generally with
unaffiliated insurance companies under traditional indemnity reinsurance
agreements. Reinsurance arrangements entered into with unaffiliated insurance
companies are in accordance with standard reinsurance practices within the
industry. As of December 31, 1996, AmerUs Life had reinsurance arrangements in
place for life insurance having a face amount of approximately $4.2 billion with
21 unaffiliated reinsurers. All of the companies with which AmerUs Life had life
reinsurance arrangements as of such date were rated "A-" or better by A.M. Best.
AmerUs Life's largest life reinsurance relationship as of December 31, 1996 was
with RGA Reinsurance Company with life reinsurance in the face amount of
approximately $1.4 billion. As of December 31, 1996, AmerUs Life's top five
reinsurers (by face amount reinsured) constituted approximately 80% of the total
face amount reinsured by AmerUs Life as of such date. Of the top five
reinsurers, four were rated "A+" and the other was rated "A++" by A.M. Best as
of December 31, 1996.
 
    AmerUs enters into indemnity reinsurance arrangements to assist in
diversifying its risks and to limit the maximum loss on risks that exceed
AmerUs' policy retention limits. AmerUs Life's present maximum retention limit
for life insurance policies is $1,000,000 per life insured. Indemnity
reinsurance does not fully discharge AmerUs' obligation to pay claims on the
reinsured business. AmerUs as the ceding insurer remains responsible for policy
claims to the extent the reinsurer fails to pay such claims. AmerUs annually
monitors the creditworthiness of its primary reinsurers, and has experienced no
material reinsurance recoverability problems in recent years.
 
  INVESTMENT PORTFOLIO
 
    General.  AmerUs maintains a diversified portfolio of investments which is
supervised by an experienced in-house staff of investment professionals. AmerUs
employs sophisticated asset management techniques in order to achieve
competitive yields, while maintaining risk at acceptable levels. The asset
portfolio is segmented by liability type, with tailored investment strategies
for specific product lines. Investment policies and significant individual
investments are subject to approval by the AmerUs Board. Management regularly
monitors individual assets and asset groups, in addition to monitoring the
overall asset mix. In addition, the Investment Committee reviews investment
guidelines and monitors internal controls.
 
    Investment Strategy.  AmerUs' investment philosophy is to employ an
integrated asset/liability management approach with separate investment
portfolios for specific product lines, such as traditional life, universal life
and annuities, to generate attractive risk-adjusted returns on capital.
Essential to this philosophy is coordinating investments in the investment
portfolio with product strategies, focusing on risk-adjusted returns and
identifying and evaluating associated business risks.
 
    AmerUs' asset/liability management approach utilizes separate investment
portfolios for specific product lines, such as traditional life, universal life
and annuities. Investment policies and strategies have been established based on
the specific characteristics of each product line. The portfolio investment
policies and strategies establish asset duration, quality and other guidelines.
AmerUs utilizes analytical systems to establish an optimal asset mix for each
line of business. AmerUs seeks to manage the asset/ liability mismatch and the
associated interest rate risk through active management of the investment
portfolio. Financial, actuarial, investment, product development and product
marketing professionals work together throughout the product development,
introduction and management phases to jointly develop and implement product
features, initial and renewal crediting strategies, and investment strategies
based on extensive modeling of a variety of factors under a number of interest
rate scenarios.
 
    In force reserves and the assets allocated to each segment are modeled to
analyze projected cash flows under a variety of economic scenarios. The result
of this modeling is used to modify asset allocation, investment portfolio
duration and convexity and renewal crediting strategies. AmerUs invests in
collateralized mortgage obligations ("CMOS") as part of its basic portfolio
strategy, but uses other types of derivatives only as a hedge against the
effects of interest rate fluctuations or to synthetically alter the investment
characteristics of specific assets. Currently, AmerUs utilizes derivatives to
support three
 
                                      115
<PAGE>
specific targeted strategies. The first strategy involves the conversion of
floating rate assets to synthetic fixed rate assets to achieve a greater
risk-adjusted return. Secondly, AmerUs uses derivatives to help protect AmerUs
against disintermediation risk in the event of a general rise in interest rates.
Finally, AmerUs uses derivative products to assist in the management of duration
mismatch of AmerUs' assets and liabilities.
 
    AmerUs seeks to manage the relationship between risk and expected return to
maintain a prudent balance between the two. Like others in the industry, AmerUs
is exposed to various potential sources of investment risk including: credit
risk relating to the uncertainty attached to the timing and amount of principal
and interest payments, interest rate risk relating to the economic effects of
changing interest rates, real estate risk relating to changes in property value
due to local economic and demographic conditions, and liquidity risk relating to
holding assets for which there is no active secondary market. AmerUs manages
credit risk principally by careful analysis of the creditworthiness of each
issuer, diversification of its holdings and prudent asset allocation. It manages
interest rate risk through sophisticated asset/liability management techniques,
including the selective use of derivative instruments. It manages real estate
risk principally by geographic and demographic diversification, careful periodic
monitoring of local economic and other conditions and by limiting loan to value
rates to acceptable levels. AmerUs manages liquidity risk principally by asset
allocation and by maintaining various credit facilities and a portfolio of
public, investment grade securities in an amount not less than 50% of the total
invested assets.
 
    The objective of AmerUs' mortgage backed securities ("MBS") investments is
to provide incremental return, while maintaining reasonable liquidity and cash
flow stability. Each MBS is evaluated to determine its interest rate sensitivity
and average life variability. In general, AmerUs seeks investments which provide
improved cash flow stability through either implicit or explicit prepayment
protection. Investments with implicit prepayment protection can take the form of
pass-throughs or CMOs backed by seasoned pools of loans which have already had
ample opportunity to refinance but have failed to do so. Explicit prepayment
protection can take the form of prepayment lockouts, yield maintenance
provisions or prepayment penalties, which are common features of multifamily
MBS, commercial MBS and FHA-insured project loans. At June 30, 1997, AmerUs' MBS
investment portfolio composition was approximately 16% fixed rate pass-throughs
backed by seasoned loan pools, 19% floating rate pass-throughs and 65% CMOs with
some form of explicit prepayment protection. AmerUs has established specific
investment guidelines for the management of MBS. As a general policy, AmerUs
does not invest in interest-only and principal-only or other similar leveraged
derivative mortgage instruments.
 
    AmerUs has improved the quality of its investment portfolio in recent years
in a number of respects. AmerUs has reduced real estate-related assets (defined
as real estate loans and real estate equity investments) as a percentage of
total invested assets from previous levels. Real estate related assets, which
totaled 19.2% of invested assets as of December 31, 1993, were reduced to 14.5%
of invested assets as of December 31, 1994, to 10.2% of total invested assets as
of December 31, 1995, to 5.8% of total invested assets as of December 31, 1996
and June 30, 1997. AmerUs' problem loan ratio (defined as aggregate delinquent,
in process of foreclosure and restructured mortgage loans) also decreased from
21.3% as of December 31, 1994 to 9.4% as of December 31, 1995, to 3.5% as of
December 31, 1996 and to 3.4% as of June 30, 1997.
 
    AmerUs in recent years has also reduced its exposure to higher risk fixed
maturity securities and common stock. AmerUs' percentage of higher risk fixed
maturity assets (defined as assets categorized in NAIC designations 3-6) was
approximately 5.3% of total invested assets as of June 30, 1997, as compared to
5.3 % as of December 31, 1996, 5.3% as of December 31, 1995 and 6.9% as of
December 31, 1994. In addition, AmerUs decreased its common stock holdings to
0.8% of total invested assets as of June 30, 1997, down from 0.9% as of December
31, 1996, 2.1% as of December 31, 1995 and 3.7% as of December 31, 1994.

<PAGE>
    Investment Monitoring and Valuation.  As part of AmerUs' investment
management process, it regularly monitors its invested assets. Fixed maturity
securities are reviewed upon receipt of the obligor's financial statements,
generally on a quarterly basis, for financial performance and historical
compliance with financial covenants. Generally, AmerUs reviews its commercial
mortgage loan and equity real estate portfolios on a monthly basis and
identifies all commercial mortgage loans and equity real estate which cause
management to conclude that such loans or investments require increased
management attention due to payment delinquencies. Detailed property analyses
and property valuations are performed annually for each commercial mortgage
loan. AmerUs generally requires borrowers to submit their financial statements
for annual review.
 
    AmerUs has policies and procedures which management believes value invested
assets fairly and consistently. As a result of the implementation of SFAS 115 as
of December 31, 1993, certain fixed maturity securities are classified as
available-for-sale, and therefore are carried at fair value in AmerUs'
Consolidated Financial Statements. Public and private fixed maturity securities
are carried principally at fair value, which is based on quoted market prices or
dealer quotes. If a quoted market price is unavailable, fair value is estimated
using values obtained from independent pricing services. In the case of private
placements, if quotes are unavailable the price is estimated by discounting
expected future cash flows using a current market rate applicable to the yield,
credit quality and maturity of the investments.
 
    Equity securities are carried principally at fair value, based on quoted
market prices. To value performing fixed interest rate mortgage loans, the
estimated net cash flows to maturity are discounted to derive an estimated
market value. The discount rate used is based on the individual loan's remaining
weighted average life and a basis point spread over the United States Treasury
yield curve at the date of valuation. Performing variable rate commercial loans
and residential loans are valued at par. Restructured, foreclosed or delinquent
loans, as well as loans to affiliates, are valued primarily at the lower of the
estimated net cash flows to maturity discounted at a market rate of interest, or
the current outstanding principal balance. Equity real estate is carried at
depreciated cost, or amortized cost for capital leases, less valuation
allowances. Equity real estate acquired in satisfaction of debt is valued at the
lower of cost or estimated fair value at the date of acquisition and is
periodically revalued. Valuation allowances for other than temporary impairments
in value are netted against the asset categories to which they apply, and
additions to valuation allowances are included in total investment results.
 
    Invested Assets.  AmerUs maintains a diversified portfolio of investments,
including public and private fixed maturity securities, commercial mortgage
loans and equity real estate. AmerUs' objective is to maintain a high-quality,
diversified fixed maturity securities portfolio that produces a yield and total
return that supports the various product line liabilities and AmerUs' earnings
goals.
 
    In connection with the AmerUs Reorganization Plan, the Closed Block was
formalized to give certain policy holders additional assurances as to the
dividend policies of AmerUs as a result of establishing the Closed Block on June
30, 1996, AmerUs allocated certain assets from its investment portfolio to the
Closed Block. See "--The AmerUs Reorganization." The following table summarizes
consolidated invested assets by asset category as of June 30, 1997 and as of
December 31, 1996 and 1995, and sets forth the allocation of such assets between
the Closed Block and the general account. The remaining information in this
Joint Proxy Statement/Prospectus relating to AmerUs' investment portfolio
presents information about the investment portfolio on a combined basis
(including invested assets in both the Closed Block and the general account).

    MBS comprise a core position within AmerUs' fixed maturity securities
investments. MBS investments include residential, commercial MBS, home equity
loans (including home equity loans purchased from one of AmerUs' affiliates, see
"--Agreements Involving Real Estate--Purchase of Loans and Securitization"),
manufactured housing, FHA Title I and CMBS. Residential mortgage pass-throughs
and CMOs total $879.2 million or 21.9% of total invested assets. As of June 30,
1997, MBS were
 
                                      119
<PAGE>
$1,254.4 million or 31.3%, of total invested assets of which $660.2 million, or
52.6% of MBS were guaranteed by the United States government or an agency of the
United States government. Other MBS were $594.2 million, or 47.4%, of MBS as of
June 30, 1997. Management believes that the quality of assets in the MBS
portfolio is generally high, with 81.6% of such assets representing agency
backed or "AAA" rated securities.
 
    AmerUs uses interest rate swaps and caps to reduce its exposure to changes
in interest rates and to manage duration mismatches. Although AmerUs is subject
to the risk that counterparties will fail to perform, credit standings of
counterparties are monitored regularly. AmerUs' policy is to contract only with
counterparties that are rated "AA" or higher; accordingly, it is expected that
counterparties will be able to satisfy their obligations under such contracts.
AmerUs is also subject to the risk associated with changes in the value of
contracts. However, such adverse changes in value generally are offset by
changes in the value of the items being hedged. The notional principal amounts
of the swaps and caps, which represent the extent of AmerUs' involvement in such
contracts but not the risk of loss, at June 30, 1997 amounted to $980.2 million.
The swaps had a carrying value and a fair value which amounted to a net
receivable position of $4.8 million at June 30, 1997. The carrying value and
fair value of interest rate caps, options and swaptions amounted to $8.0 million
and $5.3 million, respectively, and are reflected as "other investments" on
AmerUs' consolidated financial statements as of June 30, 1997. The net amount
payable or receivable from interest rate swaps and caps is accrued as an
adjustment to interest income.
 
    Mortgage Loans. As of June 30, 1997, mortgage loans in the investment
portfolio were $230.4 million, or 5.7% of the aggregate carrying value of
invested assets. Of the June 30, 1997 amount, commercial mortgage loans were
86.9%, and residential mortgage loans were 13.1%.
 
    In the last several years, AmerUs has significantly reduced its mortgage
loan investments as a percentage of its invested assets through sales of certain
mortgage loan assets, decreased originations of new loans and write-downs of
delinquent loans. As of December 31, 1993, mortgage loans totaled $652.2
million, or 17.9% of invested assets. By December 31, 1996, such investments
totaled $225.8 million, or 5.7% of invested assets and by June 30, 1997 such
investments totaled $230.4 million, or 5.7% of invested assets. Commercial
mortgage loans consist primarily of fixed-rate mortgage loans on complete
properties. As of June 30, 1997, AmerUs held 128 individual commercial mortgage
loans having an average interest rate, maturity and balance of 9.3%, 77 months
and $1.7 million, respectively.
 
    Substantially all of the new commercial mortgage loans were originated by
AmerUs through mortgage loan correspondents with whom AmerUs had an ongoing
relationship at the time such mortgage loans were originated. AmerUs is not
originating new commercial mortgage loans although it is renewing existing loans
in its portfolio in selected cases. AmerUs annually estimates the current
loan-to-value ratios of its commercial mortgage loans based on an analysis of
the operating statements of each mortgaged property.
 
    As of June 30, 1997, only $1.9 million, or 0.8%, of AmerUs' loan portfolio
(as measured by principal balance) was classified as delinquent or in
foreclosure. As of the same date, only $6.2 million, or 2.6%, of AmerUs' loan
portfolio (as measured by principal balance) was classified as restructured. For
the first six months of 1997, AmerUs had no foreclosures.
 
    In November 1994, in a transaction approved by the Iowa Commissioner, AmerUs
securitized a pool of 89 fixed rate commercial/multifamily mortgage loans with a
then outstanding aggregate principal balance of approximately $158 million.
AmerUs sold these mortgage loans to a trust. Several classes of
Commercial/Multifamily Mortgage Pass-Through Certificates, Series 1994-1
representing undivided beneficial ownership interests in the trust were then
issued and sold in a private placement. AmerUs retained a residual interest in
the trust which had a carrying value as of June 30, 1997 of $3.5 million. The
primary purpose of this securitization was to convert the mortgage loans into
cash, which could then be reinvested, and fixed maturity securities so as to
enhance AmerUs' liquidity, overall investment quality and long-term economic
value.
 
                                      120
<PAGE>
    AmerUs from time to time purchases home equity loans and residential
mortgage loans originated by certain of its affiliates. See "--Agreements
Involving Real Estate--Purchases of Loans and Securitization."
 
    Equity Real Estate. In recent years AmerUs has significantly reduced its
equity real estate portfolio. As of June 30, 1997, investment real estate
consisted of two properties located in two states. The carrying value of
investment real estate as of June 30, 1997 was $4.4 million. As of June 30,
1997, AmerUs' rental properties were 100% occupied by third parties or by
AmerUs.
 
    Other. AmerUs held $235.1 million of policy loans on individual insurance
products as of June 30, 1997. Of these policy loans, 69.5% were on traditional
life policies and 30.5% were on universal life policies and annuities. Policy
loans are permitted to the extent of a policy's contractual limits and are fully
collateralized by policy cash values. Loan rates range from 4% to 9%.
 
    As of June 30, 1997, AmerUs held equity securities of $63.0 million ($31.1
million in preferred stock). The largest holding of equity securities had a
carrying value of $28.1 million as of June 30, 1997.
 
    AmerUs held $98.6 million of other invested assets (including short-term
investments) on June 30, 1997. Other invested assets included various joint
venture investments and financial instruments.

statements regarding their ratings. Duff & Phelps reaffirmed its AA-(very high)
claims-paying ability rating of AmerUs Life. Duff & Phelps said it views the
Merger as having long term positive implications. Standard & Poor's has placed
its claims-paying rating of AmerUs Life on Credit Watch with negative
implications. Standard & Poor's stated that its action results from several
operational uncertainties. A.M. Best reaffirmed the A (excellent) rating of
AmerUs Life stating that expanded economies of scale for new business systems
and product support systems should enable it to improve earnings. Following
announcement of the acquisition of Delta, Moody's indicated that AmerUs Life,
rated A2 (good) for financial strength, was under review for possible downgrade.
Moody's has not issued any further statement with respect to AmerUs Life's
financial strength rating since announcement of the Merger.
 
    Also following the announcement of the Merger, Duff & Phelps placed the A
(high) claims-paying ability rating of American Investors Life on "rating watch
up," reflecting potential benefits of the Merger. A. M. Best affirmed its
ratings for American Investors Life and Financial Benefit Life. Moody's placed
the Ba3 (questionable) subordinated debt rating of AmVestors on review for
possible upgrade.
 
    Also following the announcement of the Merger, A. M. Best reaffirmed the A-
(excellent) rating for American Investors Life and the B+ (very good) rating for
Financial Benefit Life.
 
                                      121

    COMPETITION.  AmerUs operates in a highly competitive industry. Numerous
life insurance companies and other entities, including banks and other financial
institutions, compete with AmerUs, many of which have greater financial and
other resources as compared to AmerUs. AmerUs believes that the principal
competitive factors in the sale of insurance products are product features,
price, commission structure, perceived stability of the insurer, claims-paying
ratings, value-added service and name recognition. Many other companies are
capable of competing for sales in AmerUs' target markets (including companies
that do not presently compete in such markets). AmerUs' ability to compete for
sales is dependent upon its ability to address the competitive factors described
above.
 
    In addition to competing for sales, AmerUs competes for qualified agents and
brokers to distribute its products. Strong competition exists among insurance
companies for agents and brokers with demonstrated ability. Management believes
that the bases of competition for the services of such agents and brokers are
commission structure, support services, prior relationships and the strength of
an insurer's products. Although AmerUs believes that it has good relationships
with its agents and brokers, its ability to compete will depend on its continued
ability to attract and retain qualified persons.
 
    FEDERAL INCOME TAX CONSIDERATIONS.  Certain of the life insurance products
and annuities marketed and issued by AmerUs and the Ameritas Joint Venture enjoy
income tax advantages as compared to other savings investments, such as
certificates of deposit and taxable bonds. One important tax advantage is the
deferral of income taxation on any increases in the contract values during the
accumulation phase of the life insurance and annuities in contrast to the
current taxation of all earnings on many other savings and investment products.
In the event that the federal income tax laws are changed so that accumulated
earnings on these life insurance policies and annuities do not enjoy the tax
deferral described above, or so that additional savings and investment products
achieve similar tax deferral status, or so that tax rates are significantly
lower so that the policyowner's or annuitant's ability to defer income tax on
policy or annuity earnings is no longer a significant factor for the
policyowner, consumer demand for the affected products could decline materially.
From time to time, Congress has considered proposals to revise or eliminate this
tax deferral. There is no such proposal currently pending in Congress, nor has
the current administration announced any consideration of any such proposal. If
legislation were enacted to eliminate the tax advantages of life insurance
policies and annuities, such a change could have an adverse effect on the
ability of AmerUs to sell those products.
 
    EMPLOYEES.  As of June 30, 1997, AmerUs had 407 full-time employees. None of
AmerUs' employees are covered by a collective bargaining agreement and AmerUs
believes that its relations with employees are satisfactory.
 
    Certain employees of AmerUs also provide services to other affiliated
entities, including affiliates not directly owned by AmerUs. See "--Certain
Transactions and Relationships."
 
    SUBSIDIARIES.  AmerUs was formed in August, 1996 in connection with the
AmerUs Reorganization. See "The AmerUs Reorganization ." AmerUs' principal
subsidiaries are AmerUs Life and Delta. In addition, AmerUs Life currently owns
a 34% interest in AMAL Corporation, through whose wholly-owned subsidiaries the
Ameritas Joint Venture operates. See "--Ameritas Joint Venture." Delta's
principal subsidiary is Delta Life.
 
    LEGAL PROCEEDINGS.  AmerUs Life is a defendant in a class action lawsuit,
COZAD V. AMERICAN MUTUAL LIFE INSURANCE COMPANY, which was brought on August 31,
1995 in the District Court for Travis County, Texas. The complaint, which seeks
unspecified damages, was filed by former policyowners on behalf of themselves
and all similarly situated persons who purchased certain individual life
insurance policies which were underwritten and sold by AmerUs Life within Texas
and which were allegedly based upon uniform sales presentations and policy
illustrations from and after 1980. AmerUs Life has denied the allegations
contained in such complaint.
 
    Following a court-initiated mediation process, AmerUs and the plaintiffs
have entered into a nationwide class settlement of certain market conduct issues
for a substantial block of its policies. On
 
                                      122
<PAGE>
September 16, 1997, the court entered an order approving the certification of
the class and the fairness of the settlement.
 
    Due to the potential that a settlement may be reached in this case, AmerUs
incurred a significant charge to income in 1996. Based upon its current
estimates of the range of loss at between five and eight million dollars, AmerUs
has established a reserve of five million dollars. The eventual costs of the
settlement cannot be precisely determined at this time, and may be more or less
than the amount of the range.
 
    A class action lawsuit, BHAT V. AMERUS LIFE INSURANCE COMPANY, was also
filed in December 1996 in the United States District Court for the Northern
District of California. The complaint alleges that AmerUs Life breached the
terms of certain life and annuity policies, and breached certain other duties
owed to policyowners, when it allegedly passed an increase in its corporate
income taxes (known as the deferred acquisition cost, or DAC, tax) through to
owners of those policies. The complaint also includes RICO allegations. The
plaintiff, an insured under a universal life policy issued by Central Life,
seeks unspecified actual and punitive damages and injunctive relief on behalf of
himself and all policyowners of AmerUs Life with universal life, term and
"blended" life insurance policies and annuities. AmerUs Life denies the
allegations contained in the complaint, including the existence of a legitimate
class. The litigation is in the discovery stage and is being vigorously defended
by AmerUs Life. A hearing on certification of the class has not yet been
scheduled. At this time, AmerUs cannot determine the ultimate outcome of this
litigation or the amount of potential liability, if any.
 
    Despite AmerUs' vigorous defense of these class action lawsuits and its
denial of any wrongdoing, there can be no assurance that the outcome of such
lawsuits will not have a material adverse effect on the life insurance industry
generally or on AmerUs. See "RISK FACTORS--Risks of Class Action Litigation."
 
    In the ordinary course of business, AmerUs and its subsidiaries are also
engaged in certain other litigation, none of which management believes is
material.
 
    PROPERTIES.  AmerUs' principal business operations are conducted from two
locations. AmerUs' executive offices are located at 699 Walnut Street, Des
Moines, Iowa. AmerUs Life's executive offices are located at 699 Walnut Street,
Des Moines, Iowa. AmerUs and AmerUs Life both lease offices from an affiliate,
AmerUs Properties, Inc. See "--Certain Transactions and Relationships."
 
    Delta leases its executive offices, which are located at 530 Oak Street,
Memphis, Tennessee.
 
    SUPERVISION AND REGULATION.  AmerUs is indirectly owned by AMHC, a mutual
insurance holding company. A mutual insurance holding company is subject to
regulation at a level substantially equal to that of an Iowa domestic insurance
company, and is governed by statutory and regulatory requirements which are
identical to, or which parallel, the regulatory requirements imposed upon Iowa
domestic insurance companies. The Iowa Commissioner has jurisdiction over an
intermediate holding company, such as AmerUs, as if it were a mutual insurance
holding company.
 
    AMHC and AmerUs are each subject to the Iowa Insurer Supervision,
Rehabilitation and Liquidation Act, Iowa Code Chapter 507C. In addition, AMHC
and AmerUs are subject to the provisions of the Iowa Insurance Holding Company
Systems Act in the same manner and substantially to the same extent as domestic
insurance companies. In addition, the assets of AMHC and AmerUs are available to
satisfy claims of policyowners of AmerUs Life, in the same manner as a domestic
insurance company in the event the Iowa Commissioner initiates a proceeding
under Chapter 507C.
 
    AMHC and AmerUs may not merge with or be acquired by another entity without
approval of the Iowa Commissioner. In addition, in the case of a merger or
consolidation, separate approval by the Iowa Attorney General is required. The
statutory provisions applicable to the demutualization of a domestic mutual life
insurance company are applicable to the demutualization of a mutual insurance
holding company. In addition, no person may acquire or make an offer to acquire
voting stock in AmerUs if such acquisition would result in such person's
obtaining control over AmerUs. Generally, any person who,
 
                                      123
<PAGE>
directly or indirectly, owns, controls, holds with the power to vote, or holds
proxies representing 10% or more of AmerUs' voting securities (consisting of
both AmerUs Class A Common Stock and AmerUs Class B Common Stock) is deemed to
have control.
 
    Under rules adopted by the Iowa Commissioner, AMHC is required to provide to
the Iowa Division of Insurance an annual report containing historical and
prospective information, including financial statements, an investment plan
covering all assets, any intention it has of borrowing money and information
regarding any "closed block" formed as part of the AmerUs Reorganization.
 
    In addition to rules establishing the terms and conditions pursuant to which
the Iowa Commissioner will approve the sale of stock of an intermediate
insurance holding company or a subsidiary stock insurance company resulting from
the AmerUs Reorganization pursuant to Iowa law, the Iowa Commissioner has
adopted rules that also limit the activities and affiliations that are
permissible for mutual insurance holding companies. Under such rules, among
other things, (i) at least 50 percent of the GAAP net worth of the mutual
insurance holding company must be invested in insurance company subsidiaries;
(ii) a mutual insurance holding company may not pay any policy credit, dividend
or other distribution to any policyowner member unless such payment has been
approved by the Iowa Commissioner; and (iii) at any time a mutual holding
company acquires or plans to acquire more than 50 percent of a stock insurance
company, a mutual insurance holding company must submit to the Iowa Commissioner
a plan describing any membership interests of policyowners.
 
    The Iowa Commissioner also has issued rules which require prior approval by
the Iowa Commissioner of the issuance of stock by AmerUs. Under such rules,
AmerUs is required to give notice to the Iowa Commissioner prior to any public
or private common stock offering.
 
    Shares of the capital stock of AmerUs Life which carry the right to cast a
majority of the votes entitled to be cast by all of the outstanding shares of
AmerUs Life are required by Iowa law to at all times be owned, directly or
indirectly, by AMHC and may not be conveyed, transferred, assigned, pledged,
subjected to a security interest or lien, encumbered, or otherwise hypothecated
or alienated by AMHC or any intermediate holding company. Any conveyance,
transfer, assignment, pledge, security interest, lien, encumbrance or
hypothecation or alienation by AMHC, or any intermediate holding company, in or
on such shares shall be deemed void in inverse chronological order of the date
of such transaction to the extent necessary to give the mutual insurance holding
company unencumbered direct or indirect ownership of shares representing a
majority of the votes entitled to be cast by all of the outstanding shares of
AmerUs Life.
 
    Regulation of Life Insurance Subsidiaries.  AmerUs relies primarily on
dividends and interest income from AmerUs Life and Delta to make any dividend
payments to its shareholders. The ability of AmerUs Life to pay dividends to
AmerUs is limited by law to earned profits (statutory unassigned surplus) as of
the date the dividend is paid, as determined in accordance with accounting
practices prescribed or permitted by the insurance regulatory authorities of the
State of Iowa. In addition, under the Iowa Insurance Holding Company Systems
Act, AmerUs Life may not pay an "extraordinary" dividend without prior notice to
and approval by the Iowa Commissioner. An "extraordinary" dividend is defined
under the Iowa Holding Company Systems Act as any dividend or distribution of
cash or other property whose fair market value, together with that of other
dividends or distributions made within the preceding 12 months exceeds the
greater of (i) 10% of policyowners' surplus (total statutory capital stock and
statutory surplus) as of December 31 of the preceding year, or (ii) the
statutory net gain from operations of the insurer for the 12 month period ending
the December 31 of the preceding year. Iowa law gives the Iowa Commissioner
broad discretion to disapprove requests for dividends in excess of these limits.
Based on this limitation and 1996 statutory results, and absent the AmerUs
Reorganization, AmerUs Life would have been able to pay approximately $34
million in dividends to AmerUs in 1997 without obtaining the Iowa Commissioner's
approval. However, as a result of the AmerUs Reorganization AmerUs Life is not
able to pay any additional dividends until December 1997 without the prior
approval of the Iowa Commissioner. Thus far in 1997, AmerUs Life has requested
and received approval
 
                                      124
<PAGE>
for the payment of $10 million in dividends. See "RISK FACTORS--Holding Company
Structure; Limitations on Dividends." The payment of dividends by Delta is
regulated under Tennessee law, which has statutory limitations similar to
Iowa's. Based on these limitations and 1996 statutory results, Delta could pay
$8.7 million in dividends in 1997.
 
    AmerUs' life insurance subsidiaries are subject to regulation and
supervision by the states in which they transact business. State insurance laws
generally establish supervisory agencies with broad administrative and
supervisory powers related to granting and revoking licenses, transacting
business, establishing guaranty fund associations, licensing agents, approving
policy forms, regulating premium rates for some lines of business, establishing
reserve requirements, prescribing the form and content of required financial
statements and reports, determining the reasonableness and adequacy of statutory
capital and surplus, and regulating the type and amount of investments
permitted.
 
    Every state in which AmerUs' life insurance subsidiaries are licensed
administers a guaranty fund, which provides for assessments of licensed insurers
for the protection of policyowners of insolvent insurance companies. There has
been an increase in the number of insurance companies that are under supervision
which has resulted in an increase in the amount of assessments to cover losses
to policyowners of such companies. Assessments can be partially recovered
through a reduction in future premium taxes in some states. In these situations,
the assessments are generally capitalized and amortized against future
reductions in premium taxes. Management cannot reasonably predict the amount of
such future assessments, if any.
 
    Ethical sales practices and compliance with applicable laws and regulations
relevant to the life insurance industry have been a continuing focus of AmerUs'
support efforts. AmerUs has a continuing education program focusing on ethical
practices which is being provided to all agents. A program is currently being
implemented to further formalize AmerUs' current practices and standards in the
compliance and market conduct areas.
 
    Recently, the insurance regulatory framework has been placed under increased
scrutiny by various states, the federal government and the NAIC. Various states
have considered or enacted legislation which changes, and in many cases
increases, the state's authority to regulate insurance companies. Although
legislation has been under consideration for several years in Congress which, if
enacted, would result in the federal government assuming some role in the
regulation of insurance companies, management does not expect the current
Congress to enact federal insurance regulation. The NAIC, in conjunction with
state regulators, has been reviewing existing insurance laws and regulations.
The NAIC recently approved and recommended to the states for adoption and
implementation several regulatory initiatives designed to reduce the risk of
insurance company insolvencies. Through the NAIC accreditation program, these
recommendations for state legislation have taken on an increased significance.
Two such initiatives which have been adopted by the NAIC are risk-based capital
standards ("RBC") and a model investment law.
 
    The RBC standards for life insurance companies were adopted by the NAIC in
1992 and require insurance companies to calculate and report for statutory basis
financial statements information under a risk-based capital formula. The formula
is embodied in the NAIC Model Act, which has been adopted by many states,
including Iowa. RBC requirements are intended to allow insurance regulators to
identify at an early stage inadequately capitalized insurance companies based
upon the types and mixtures of risks inherent in such companies' operations. The
formula includes components for asset risk, liability risk, interest rate
exposure and other factors. As of June 30, 1997, AmerUs Life's and Delta Life's
RBC levels were 800% and 529%, respectively, of the authorized control level RBC
thresholds.
 
    The RBC requirements are intended to be used by insurance regulators as an
early warning tool to identify deteriorating or weakly capitalized companies for
the purpose of initiating regulatory actions. They are not designed as a ranking
mechanism for adequately capitalized companies. In addition, the formula defines
a new minimum capital standard which supplements the low, fixed minimum capital
and surplus requirements previously implemented on a state-by-state basis.
 
                                      125
<PAGE>
    The NAIC RBC requirements categorize insurance companies according to the
extent to which they meet or exceed certain RBC thresholds. The law requires
increasing degrees of regulatory oversight and intervention based on the level
of an insurance company's authorized control level RBC as its RBC declines.
These degrees of regulatory action are triggered by the RBC level of an
insurance company as follows: (i) a "Company Action Level Event" (requiring the
insurance company to inform and obtain approval from the Director of a
comprehensive financial plan for increasing its RBC), which would occur if,
among other things, an insurance company's RBC falls below 200% of its
authorized control level RBC, or if an insurance company's RBC falls below 250%
of its authorized control level RBC and has a negative trend; (ii) a "Regulatory
Action Level Event" (resulting in, in addition to the requirement of a financial
plan, regulatory actions including examination of an insurance company's assets,
liabilities and operations followed by an order specifying such corrective
actions as the Director determines to be appropriate), which would occur if,
among other things, an insurance company's RBC falls below 150% of its
authorized control level RBC; (iii) an "Authorized Control Level Event"
(resulting in, in addition to the regulatory actions above, such actions as are
necessary to cause an insurance company to be placed under regulatory control in
a rehabilitation or liquidation proceeding if deemed to be in the best interests
of policyowners, creditors and the public), which would occur if, among other
things, an insurance company's RBC falls below 100% of its authorized control
level RBC; and (iv) a "Mandatory Control Level Event" (resulting in, on a
mandatory basis, such actions as are necessary to cause an insurance company to
be placed under regulatory control in a rehabilitation or liquidation
proceeding), which would occur if, among other things, an insurance company's
RBC falls below 70% of its authorized control level RBC.
 
    Approximately once every three to five years, as part of their routine
regulatory oversight process, state insurance departments conduct detailed
examinations of the books, records and accounts of insurance companies domiciled
in their states. Such examinations are generally conducted in cooperation with
the departments of two or three other states, under guidelines promulgated by
the NAIC. AmerUs Life was last examined by the Iowa Commissioner as of December
31, 1993. No material issues were raised by the Iowa Commissioner in such
examination. However, AmerUs has been notified that the Iowa Commissioner will
commence an examination of AmerUs Life for the years 1994, 1995 and 1996, which
examination is scheduled to begin in late 1997. The last examination of Delta by
the Tennessee Insurance Commissioner occurred in 1993. No material issues were
raised by the Tennessee Commissioner in such examination.
 
    The NAIC has recently adopted model legislation to govern insurance company
investments. In addition, draft alternative model legislation is also under
discussion at the NAIC level. However, implementation of any investment model
law into state law is not anticipated in the foreseeable future. Management
believes that if the recently adopted model law or the current alternative
discussion draft were adopted without modification it would not have a material
impact on AmerUs.
 
    Certain of AmerUs' insurance and annuity products are innovative and
relatively new. The regulatory framework at the state and federal level
applicable to such products is evolving and has not fully developed. The
developing regulatory framework could affect the design of such products and
AmerUs' ability to sell certain products. For example, on August 20, 1997, the
SEC issued a concept release in which the SEC has requested information and
comments about the structure of equity index insurance products, the manner in
which they are marketed and the federal securities law issues raised by equity
index insurance products. Although the release does not set forth any proposed
rules or new SEC policy with respect to such matters, it is possible that,
following receipt of comments, the SEC may propose new regulations or policies
with respect to equity index insurance products which may affect the marketing
of such products or impose requirements that some or all of such products be
registered with the SEC.
 
    CERTAIN TRANSACTIONS AND RELATIONSHIPS.  THE FOLLOWING SUMMARIES OF THE
INTERCOMPANY AGREEMENT AND OTHER AGREEMENTS IDENTIFIED DO NOT PURPORT TO BE
COMPLETE AND ARE QUALIFIED IN THEIR ENTIRETY BY REFERENCE TO SUCH AGREEMENTS. AS
USED HEREIN, "AMERUS AFFILIATED GROUP" MEANS AMHC AND ITS DIRECT AND INDIRECT
SUBSIDIARIES NOW OR HEREAFTER EXISTING, OTHER THAN AMERUS AND ITS SUBSIDIARIES,
AND "AMERUS
 
                                      126
<PAGE>
CONTROL GROUP" MEANS, COLLECTIVELY, AMHC AND AMERUS GROUP. CAPITALIZED TERMS
USED BUT NOT DEFINED HEREIN HAVE THE MEANINGS GIVEN TO THEM IN SUCH AGREEMENTS.
 
    AmerUs Life is a wholly-owned direct subsidiary of AmerUs. AmerUs is a
direct subsidiary of AmerUs Group, which in turn is a wholly-owned direct
subsidiary of AMHC. As a result of such ownership, AMHC, AmerUs Group, the other
subsidiaries of AmerUs Group and AmerUs and its subsidiaries, including AmerUs
Life, have a variety of relationships, certain of which are summarized below.
Management believes that the terms of the agreements described herein are on a
basis no less favorable than could be obtained from unaffiliated third parties.
 
    OWNERSHIP OF VOTING INTERESTS OF AMERUS.  As a result of the AmerUs
Reorganization of AmerUs and its affiliates into a mutual insurance holding
company structure, AMHC is required by Iowa law to own, directly or indirectly
through one or more intermediate holding companies, shares of capital stock of
AmerUs Life which carry the right to cast a majority of the votes entitled to be
cast by all of the outstanding shares of the capital stock at a shareholders'
meeting of AmerUs Life. See "--Supervision and Regulation." In compliance with
this requirement, all of the issued and outstanding shares of AmerUs Class B
Common Stock are owned by AmerUs Group, a wholly-owned subsidiary of AMHC.
AmerUs Group also owns a substantial number of shares of AmerUs Class A Common
Stock. See "SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND
MANAGEMENT--AmerUs Common Stock." Additionally, AmerUs' Charter provides that no
shares of its Class B Common Stock may be owned by any person other than AMHC, a
subsidiary of AMHC or another mutual insurance holding company or intermediate
holding company as expressly authorized by Iowa law or by the Iowa Commissioner.
Any proposed amendments to such provisions of the AmerUs Charter are subject to
approval by the Iowa Commissioner and the Iowa Attorney General. See
"DESCRIPTION OF AMERUS CAPITAL STOCK."
 
    AMHC'S POLICY WITH RESPECT TO CORPORATE OPPORTUNITIES.  AmerUs has been
advised that AMHC has adopted a general policy with respect to certain corporate
opportunities presented to AMHC. The implementation of such policy in any
situation is expressly subject to any applicable regulatory, tax, contractual or
legal restrictions as well as issues as to feasibility. Pursuant to such policy,
so long as AMHC directly or indirectly owns at least 50.1% of the voting power
of the outstanding common stock of AmerUs (the "VOTING CONTROL PERIOD"), AMHC
intends to first offer to AmerUs any corporate opportunity relating to the
acquisition of any stock life insurance company or any company (other than a
mutual insurance holding company) primarily engaged in owning a stock life
insurance company. During the Voting Control Period, AMHC also intends to first
offer to AmerUs any corporate opportunity primarily relating to a joint venture,
partnership, or similar affiliation in the life insurance or annuity industry.
During the Voting Control Period, in the event that AMHC merges with a mutual
insurance holding company owning a stock life insurance company or a mutual
insurance company is reorganized pursuant to Chapter 521A of the Iowa Code into
a stock life insurance company subsidiary of AMHC, AMHC intends, if the other
party to the transaction agrees, to offer AmerUs the corporate opportunity to
combine such acquired company with AmerUs or a subsidiary thereof in exchange
for appropriate consideration.
 
    Any combination would be on terms which are approved by a majority of the
independent directors of AMHC and AmerUs and set forth in a written agreement
between the parties. However, neither AMHC nor AmerUs is obligated to take any
action which is not consistent with their respective fiduciary duties or
applicable contractual, regulatory, tax or legal requirements. Moreover, the
results of negotiations with parties interested in a potential transaction or
other factors, such as feasibility or a desire to maintain the separate
identities and assets of two insurers, may result in AMHC not presenting a
potential transaction to AmerUs or a company acquired by AMHC not being combined
with AmerUs or a subsidiary thereof.
 
    Under AMHC's policy, a corporate opportunity is considered to be a business
opportunity in the life insurance and annuity business known to AMHC which
AmerUs is legally and financially able to undertake, is of practical advantage
to AmerUs and is one in which AmerUs has an interest or a reasonable expectancy.
If AmerUs does not choose to pursue a corporate opportunity within a reasonable
period after such opportunity is first presented to it, AMHC would not intend to
afford AmerUs any further opportunity with respect to such potential
transaction.
 
                                      127
<PAGE>
    AMERUS INTERCOMPANY AGREEMENT.  AMHC, AmerUs Group and AmerUs have entered
into an Amended and Restated Intercompany Agreement dated as of December 1, 1996
(the "AMERUS INTERCOMPANY AGREEMENT"), certain provisions of which are
summarized below.
 
    LICENSE TO USE THE AMERUS NAME AND CERTAIN TRADEMARKS. Pursuant to the
AmerUs Intercompany Agreement, AmerUs Group and certain members of the AmerUs
Affiliated Group have granted to AmerUs and certain of its subsidiaries, a
non-exclusive, revocable license to use the AmerUs name and certain trademarks
(collectively, the "TRADEMARKS") solely in connection with AmerUs' life
insurance business and activities related to such life insurance business. The
AmerUs Intercompany Agreement provides, among other things, that subject to
AmerUs Group's ability to revoke the license in the circumstances described
below and subject to regulatory approval, within a specified time from the date
on which the AmerUs Control Group ceases to control more than 50% of the
combined voting power of the outstanding Common Stock (the "LICENSE TRIGGER
DATE"), if AmerUs' name or any of its subsidiaries' names at such time includes
the "AmerUs" name, AmerUs and such subsidiaries will be required to change their
names and will be required to discontinue the use of certain related marks.
Following the License Trigger Date, AmerUs and its subsidiaries will continue to
have the right to use the AmerUs name in connection with the identification of
insurance products for an initial five-year period with an option to renew for
an additional five years, for which AmerUs will pay a nominal annual fee to
AmerUs Group until such time as AmerUs and its subsidiaries completely
discontinue use of the "AmerUs" name. In addition, the AmerUs Intercompany
Agreement provides that AmerUs and its subsidiaries will not, without the prior
written consent of AmerUs Group, take any action with respect to (i) any
litigation or proceeding involving the Trademarks, (ii) any change in AmerUs'
names, logos and other identifications that might reasonably be expected to
affect the Trademarks or (iii) any advertising campaigns or strate-gies that use
the Trademarks or that refer to any member of the AmerUs Affiliated Group.
AmerUs Group has the right to revoke the license under certain circumstances
relating to advertising, promotion or use of the Trademarks in a manner contrary
to AmerUs Group guidelines. In addition, AmerUs Group can revoke any of AmerUs'
subsidiaries' use of the license if there is a change of control of any such
subsidiary of AmerUs that is licensed to use the Trademarks. A revocation by
AmerUs Group of the license to use the Trademarks could have a material adverse
effect on AmerUs' ability to conduct its business.
 
    INDEMNIFICATION. The AmerUs Intercompany Agreement provides that AmerUs will
indemnify each member of the AmerUs Affiliated Group and each of their
respective officers, directors, employees and agents (collectively, the
"INDEMNITEES") against losses based on, arising out of or resulting from (i) the
use of the Trademarks by AmerUs or its subsidiaries, (ii) the ownership or the
operation of the assets or properties, and the operation or conduct of the
business of AmerUs or its subsidiaries, (iii) any other activities of AmerUs or
its subsidiaries, (iv) any other acts or omissions by AmerUs or its subsidiaries
arising out of performance of the AmerUs Intercompany Agreement and certain
other agreements, (v) any guaranty, keep well, net worth or financial condition
maintenance agreement of or by any member of the AmerUs Affiliated Group
provided to any parties with respect to any actual or contingent obligation of
AmerUs or its subsidiaries, (vi) any breach by AmerUs of the AmerUs Intercompany
Agreement, and (vii) certain other matters. In addition, AmerUs has agreed to
indemnify the Indemnitees against certain civil liabilities, including
liabilities under the Securities Act, relating to misstatements in or omissions
from the Registration Statement of which this Joint Proxy Statement/Prospectus
forms a part and any other registration statement that AmerUs files under the
Securities Act (other than misstatements or omissions made in reliance on
information relating to and furnished by any member of the AmerUs Affiliated
Group for use in the preparation thereof, against which AMHC has agreed to
indemnify AmerUs). AMHC has also agreed to indemnify AmerUs and its subsidiaries
and each of their respective officers, directors, employees and agents against
losses based on, arising out of or resulting from (i) any breach by the AmerUs
Affiliated Group of the AmerUs Intercompany Agreement, (ii) the ownership or the
operation of the assets or properties, and the operation or conduct of the
business of any member of the AmerUs Affiliated Group, (iii) certain third party
claims relating to the Trademarks and (iv) certain other specifically identified
matters.

<PAGE>
    AMHC CONSENT TO CERTAIN EVENTS. The AmerUs Intercompany Agreement provides
that until the date on which the members of the AmerUs Control Group cease to
control at least 50.1% of the combined voting power of the outstanding AmerUs
Common Stock of AmerUs (the "TRIGGER DATE"), the prior written consent of AMHC
will be required for: (i) any consolidation or merger of AmerUs or any of its
subsidiaries with any person (other than certain transactions involving wholly
owned subsidiaries); (ii) any sale, lease, exchange or other disposition or any
acquisition by AmerUs or any of its subsidiaries (other than transactions to
which AmerUs and its wholly owned subsidiaries are the only parties), or any
series of related dispositions or acquisitions, involving consideration in
excess of $20 million; (iii) any change in the authorized capital stock of
AmerUs or the creation of any class or series of capital stock of AmerUs, (iv)
any issuance by AmerUs or any subsidiary of AmerUs of any equity securities or
equity derivative securities, except (a) up to three million shares of Common
Stock pursuant to employee and director stock option, profit sharing and other
benefit plans of AmerUs and its subsidiaries, (b) the issuance of Preferred
Stock which is not convertible or exchangeable into Common Stock and which only
has voting rights required by law, (c) the issuance of shares of capital stock
of a wholly owned subsidiary of AmerUs and (d) pursuant to the Transactions
(defined as AmerUs' February 1997 initial public offering and any corporate
AmerUs Reorganization or transaction undertaken in connection with the initial
public offering to which AmerUs or any of its subsidiaries is a party); (v) the
dissolution of AmerUs; (vi) transactions or a series of related transactions
with affiliates of AmerUs (other than members of the AmerUs Affiliated Group)
involving consideration in excess of $10 million, other than (a) the
Transactions, (b) transactions on terms substantially the same as or more
favorable to AmerUs than those that would be available from an unaffiliated
third party and (c) transactions between or among any of AmerUs and its wholly
owned subsidiaries; and (vii) any corporate action by AmerUs which would cause
AmerUs or AmerUs Life to violate the requirements of Section 521A.14 of the Iowa
Insurance Code (relating to mutual insurance holding companies).
 
    AmerUs has sought and received the consent of AMHC to the Merger and the
Stock Issuance.
 
    REGISTRATION RIGHTS. AmerUs has granted to the AmerUs Control Group certain
demand and "piggyback" registration rights with respect to shares of AmerUs
Common Stock owned by it. The AmerUs Control Group has the right to request up
to two demand registrations in each calendar year. The AmerUs Control Group also
has the right, which it may exercise at any time and from time to time, to
include the shares of Common Stock held by it in certain other registrations of
common equity securities of AmerUs initiated by AmerUs on its own behalf or on
behalf of any shareholder of AmerUs. Such registration rights are transferable
by the AmerUs Control Group provided that such transferee is (i) a member of the
AmerUs Control Group or (ii) in the case of AmerUs Class A Common Stock only, an
institutional accredited investor (as defined under Rule 501(a) promulgated
under the Securities Act) permitted to acquire such registrable shares under
applicable law. AmerUs has agreed to pay all costs and expenses in connection
with each such registration, except underwriting discounts, commissions and
legal fees of the AmerUs Control Group applicable to the shares of Common Stock
sold by the AmerUs Control Group. The AmerUs Intercompany Agreement contains
customary terms and provisions with respect to, among other things, registration
procedures and certain rights to indemnification granted by parties thereunder
in connection with the registration of AmerUs Common Stock on behalf of the
AmerUs Control Group.
 
    EQUITY PURCHASE RIGHTS. AmerUs has agreed that, to the extent permitted by
Nasdaq so long as AmerUs is listed on Nasdaq, and so long as the AmerUs Control
Group controls at least 50.1% of the combined voting power of the outstanding
Common Stock of AmerUs, the AmerUs Control Group may purchase its pro rata share
(based on its then current percentage equity interest in AmerUs) of any voting
equity security issued by AmerUs (excluding any such securities offered in
connection with any merger, acquisition, exchange offer, employee and director
stock option or other benefit plans, dividend reinvestment plans and other
offerings other than for cash).
 
    CERTAIN BUSINESS RELATIONSHIPS. AmerUs has agreed that all distribution
arrangements in effect as of September 15, 1996 pursuant to which members of the
AmerUs Affiliated Group distribute insurance products of AmerUs or its
subsidiaries shall continue until the Trigger Date.
 
                                      129
<PAGE>
    MANAGEMENT SERVICES.  Until the Trigger Date, AmerUs has agreed to provide
to the AmerUs Affiliated Group certain management and administrative services,
including: (i) general management services, (ii) assistance in matters relating
to operations, strategy and business planning and (iii) as requested, furnish
reports to the board of directors of AMHC or AmerUs Group with respect to
aspects of the business and affairs of the AmerUs Affiliated Group. In
connection with such services AmerUs will be subject to the exclusive authority
of the board of directors of AMHC or the AmerUs Affiliated Group member for
which such services are performed. AmerUs Group will pay AmerUs $2.0 million in
consideration for such services in 1997.
 
    TAX ALLOCATION AGREEMENT.  AmerUs and AMHC have entered into an agreement
relating to the allocation of federal and state income tax liabilities (the "TAX
ALLOCATION AGREEMENT"). Under the Tax Allocation Agreement, AmerUs will be
responsible for all income tax liabilities that are attributable to the net
income of AmerUs and its subsidiaries under applicable federal and state tax
laws. AmerUs will have no responsibility for income tax liabilities attributable
to AMHC and its wholly-owned subsidiaries under such laws, including any
liabilities that may have arisen while such subsidiaries were wholly-owned
subsidiaries of AmerUs Life. If and to the extent that losses of AMHC and its
wholly-owned subsidiaries are applied to reduce the federal or state income
taxes attributable to the net income of AmerUs, AmerUs will be required to make
a payment to AMHC equal to such tax reduction. Conversely, if and to the extent
that losses of AmerUs are applied to reduce the federal or state income tax
liability attributable to the net income of AMHC and its wholly-owned
subsidiaries for any year, AMHC will be required to make a payment to AmerUs
equal to such tax reduction. It is not anticipated that the federal or state
income tax liability of AmerUs or its subsidiaries will be determined on a
consolidated or combined basis with that of AMHC or any of its wholly-owned
subsidiaries for any period after the Merger.
 
    AGREEMENTS INVOLVING REAL ESTATE.  AmerUs Life has entered into asset and
property management contracts with API. Pursuant to such agreements, API
provides asset and property management services to AmerUs Life with respect to
certain real estate owned by AmerUs Life. The total expenses incurred by AmerUs
Life pursuant to such agreements equaled approximately $1,108,000 and $33,000
for the year ended December 31, 1996 and the six months ended June 30, 1997,
respectively.
 
    Total rental income earned by AmerUs under all agreements with members of
the AmerUs Affiliated Group was approximately $474,000 for the year ended
December 31, 1996 and none for the six months ended June 30, 1997.
 
    AmerUs entered into lease agreements with API in December 1996 because the
facilities occupied by AmerUs as its executive and home offices were transferred
to API as part of the AmerUs Reorganization. The lease agreements require
monthly payments of $143,000 on a net basis for a period of 5 years. In
addition, AmerUs leases additional space on a monthly basis. Total rent paid
under these agreements was $143,000 and $943,000 for the year ended December 31,
1996 and the six months ended June 30, 1997, respectively.
 
    AmerUs Life paid rentals to AmerUs Bank of $24,000 for the year ended
December 31, 1996, under the terms of a lease agreement which expired in 1996.
 
    AmerUs Life has entered into various limited partnership and joint venture
agreements in which API or an affiliate serves as general partner. AmerUs Life
contributed portions of its joint venture interests to API and sold several of
these partnership interests to newly formed partnerships in which API has an
interest. Total proceeds from these sales were $1,638,000 and $10,979,000 in the
year ended December 31, 1996 and in the six months ended June 30, 1997,
respectively. After such sales, AmerUs Life purchased a 9.75% limited
partnership interest in one of the newly formed partnerships for $2,160,000. In
addition, AmerUs Life agreed to make loans to the newly formed partnerships in
the aggregate amount of up to $20,000,000 of which none was outstanding as of
June 30, 1997.
 
    AmerUs Life has also entered into agreements with various partnerships in
which API has an interest pursuant to which AmerUs Life is obligated to make
future capital contributions to such partnerships in an amount of up to
$4,643,000.
 
                                      130
<PAGE>
    As of June 30, 1997, AmerUs Life had a total investment of $9,052,000 in
various partnerships and joint ventures in which API had an interest.
 
    LOAN SERVICING AGREEMENTS.  AmerUs Life has entered into various loan
servicing agreements with various members of the AmerUs Affiliated Group. The
total expenses incurred by AmerUs Life for such services was approximately
$1,420,000 and $186,000 for the year ended December 31, 1996 and the six months
ended June 30, 1997, respectively.
 
    AmerUs Life has also entered into various loan servicing agreements with
AmerUs Bank. Pursuant to such agreements, AmerUs Life services certain
nonresidential mortgage loans on behalf of AmerUs Bank. The total revenues
earned by AmerUs Life for such services were approximately $28,000 and $13,000
for the year ended December 31, 1996 and the six months ended June 30, 1997,
respectively.
 
    OTHER SERVICE AGREEMENTS.  AmerUs and AmerUs Life have entered into various
miscellaneous services agreements with members of the AmerUs Affiliated Group.
Pursuant to such agreements, AmerUs and AmerUs Life provide certain
communications, tax, law department, accounting department, internal audit,
administrative and data processing services to such other parties to the
agreements, as requested. The aggregate revenues earned for services performed
by AmerUs and AmerUs Life in accordance with such agreements were approximately
$7,119,000 and $2,961,000 for the year ended December 31, 1996 and the six
months ended June 30, 1997, respectively.
 
    PURCHASE OF LOANS AND SECURITIZATION.  AmerUs Life entered into a purchase
agreement with AmerUs Bank, dated as of June 28, 1996, pursuant to which AmerUs
Life acquired an HEL Asset-Backed Class A Note (the "NOTE") and Class R
Certificate Series 1996-1 (the "CERTIFICATE"). The Note had a face amount of
$43,715,845 and pays interest at the rate of 8.35% per annum. The Certificate
has a face amount of $3,039,069 and pays interest at the rate of 16.81% per
annum. The Note and Certificate are backed by the assets of the AB Home Equity
Loan Trust (the "AB TRUST"), which consist of approximately $47 million of
second mortgage loans. Pursuant to a Pooling and Servicing Agreement, dated as
of June 28, 1996 (the "Pooling and Servicing Agreement"), between AmerUs Bank
and Boatmen's Trust Company ("BOATMEN'S"), and a Transfer Agreement, dated as of
June 28, 1996, between AmerUs Bank and Boatmen's, as trustee of the AB Trust,
the AB Trust acquired such loans from AmerUs Bank, and paid a purchase price of
$46,754,914. Under the Pooling and Servicing Agreement AmerUs Bank acts as the
servicer of the loans and receives a servicing fee equivalent to the amount of
all interest collected on the loans in excess of 8.9%.
 
    AmerUs Life entered into a master agreement of purchase and sale with AmerUs
Bank, dated as of March 5, 1997, whereby the terms under which AmerUs Life would
purchase home equity mortgage loans from AmerUs Bank was established. AmerUs
Life records the purchase of such loans at their purchase price which represents
fair market value, which may be different from AmerUs Bank's carrying value.
AmerUs would accordingly recognize gain or loss on such transactions. To date,
AmerUs Life has acquired loans with aggregate principal balances at the time of
sale of $98,476,213. Most of the acquired loans were sold by AmerUs Life on
October 24, 1997, to Bank of New York, as Trustee of the AmerUs Home Equity Loan
Trust 1997-1 (the "TRUST") in a $125 million offering of home equity loans. Of
the $125 million, $30,947,779 was set aside under the Pooling and Servicing
Agreement to be used by AmerUs Life to acquire additional home equity mortgage
loans for inclusion in the Trust. AmerUs Life services the loans in the Trust
and AmerUs Bank acts as a subservicer of the loans and receives a pass-through
of the servicing fee of 50 basis points of the outstanding principal balances of
the loans.
 
    AmerUs Life entered into a purchase agreement with AmerUs Mortgage dated
March 1, 1997, whereby AmerUs Life has committed to purchase up to $200 million
principal amount of first mortgage loans originated by AmerUs Mortgage. The
commitment expires on December 31, 1997, and is terminable by either party upon
sixty days' notice. As of October 31, 1997, AmerUs Life has purchased 58
mortgage loans pursuant to such commitment for a total purchase price of
$8,453,000.
 
    SALE OF INSURANCE POLICIES.  AmerUs Life has entered into an agreement,
dated January 1, 1995, with AmerUs Investments, Inc. ("AMERUS INVESTMENTS"), a
wholly-owned subsidiary of AmerUs Bank, to
 
                                      131
<PAGE>
market products of AmerUs Life. Pursuant to this agreement, AmerUs Life pays
AmerUs Investments fees in the form of commissions in exchange for generating
sales of such products. Total commissions paid to AmerUs Investments were
$521,000 and $683,000 for the year ended December 31, 1996 and six months ended
June 30, 1997, respectively.
 
    AmerUs has also entered into certain Affiliated Agent Contracts with
employees of AmerUs Investments (the "AFFILIATED AGENTS") to solicit, sell and
service AmerUs Life insurance products and has also entered into a Servicing
Agreement, dated March 1, 1992, with AmerUs Investments pursuant to which AmerUs
Investments agreed to service the business sold by any Affiliated Agent and
otherwise supervise its employees who are Affiliated Agents.
 
    CAPITAL CONTRIBUTION.  During 1996, AmerUs Life made a capital contribution
to or for the benefit of certain of its subsidiaries in connection with the
AmerUs Reorganization. The capital contribution consisted of cash and other
property having an approximate net carrying value of $79 million. After making
such capital contribution, AmerUs Life caused certain of its non-life insurance
subsidiaries to be distributed to AmerUs Group, effectively separating AMHC's
non-life insurance businesses from the life insurance businesses owned by
AmerUs.
 
    From time to time AmerUs Life has made capital contributions to Lartnec
Investment Co. ("LARTNEC"). Lartnec had previously been a subsidiary of AmerUs
Life, and AmerUs Financial Services, Inc. ("AFS") had previously been a
subsidiary of Lartnec. During 1996, AFS was merged into Lartnec and Lartnec was
then merged upstream into AmerUs Life, after which the distribution of the non-
life insurance subsidiaries to AmerUs Group was effected. During 1996, AmerUs
Life made capital contributions to Lartnec in the approximate total amount of
$4,463,000 prior to Lartnec's liquidation.
 
    LOANS AND CREDIT SUPPORT TO THE AMERUS AFFILIATED GROUP.  AmerUs Life has
provided financing to members of the AmerUs Affiliated Group or their affiliates
for various purposes. The outstanding balance of all such financings was $62
million and $58 million as of December 31, 1996 and June 30, 1997, respectively.
AmerUs Life recorded interest income of $5.0 million and $2.6 million for the
year ended December 31, 1996 and the six months ended June 30, 1997,
respectively. All such loans were made on terms which were intended to
approximate arms' length transactions.
 
    AmerUs Life pledged investment securities as collateral for indebtedness of
the AmerUs Affiliated Group. Approximately $62.0 million was outstanding under
the facility at December 31, 1996. The value of the collateral pledged was
approximately $88.0 million as of December 31, 1996. No collateral was pledged
as of June 30, 1997 for indebtedness of the AmerUs Affiliated Group.
 
    In addition, AmerUs Life guaranteed various borrowings of members of the
AmerUs Affiliated Group with outstanding balances of approximately $7.1 million
and $7.0 million at December 31, 1996 and June 30, 1997, respectively.
 
    AmerUs Life has outstanding loan commitments to various partnerships in
which API has an interest. At June 30, 1997, the outstanding loan commitments
were approximately $15,000,000.
 
    RESTRICTIONS UNDER AMERUS GROUP FINANCING__In January 1997, AmerUs Group
entered into a revolving credit facility with a syndicate of lenders secured by
a pledge of certain of the outstanding capital stock held by AmerUs Group in its
direct and indirect subsidiaries, including AmerUs and AmerUs Life. As of
October 31, 1997, AmerUs Group had not made any borrowings under the credit
facility and there were no outstanding loan amounts under that facility. The
credit facility provides for typical events of default and covenants with
respect to the conduct of the business of AmerUs Group and its subsidiaries and
requires the maintenance of various financial levels and ratios. Among other
covenants, AmerUs Group is required to ensure that (a) AmerUs maintains certain
specified financial ratios with respect to minimum consolidated net worth,
adjusted capital and surplus, cash flow to fixed charges, and leverage, (b)
AmerUs Life, Delta Life and any other material life insurance subsidiary
maintain a specified ratio of risk-based capital, and (c) AmerUs Life maintains
a rating by A.M. Best of "A-" or better (provided that no event of default will
occur under the credit facility until the earlier to occur of AmerUs Life's
rating falling below "B++" or 12 months after AmerUs Life's rating falling below
"A-").
 
                                      132
<PAGE>
    SECURITY ARRANGEMENTS FOR BANK CREDIT FACILITY.  In connection with the Bank
Credit Facility (as defined below), AmerUs has pledged to the lenders
approximately 49.9% of the common stock of AmerUs Life owned by AmerUs and a $50
million 9% surplus note payable to AmerUs by AmerUs Life.
 
    TRANSACTIONS WITH AFFILIATES OF DIRECTORS.  John A. Wing, a director of
AmerUs, is Chairman and Chief Executive Officer of ABN AMRO Chicago Corporation.
ABN AMRO Chicago Corporation has from time to time performed investment banking
services for AmerUs, including assisting AmerUs with its subscription offering
and serving as co-manager of AmerUs' initial public offering of its AmerUs Class
A Common Stock. The total amount of fees paid by AmerUs to ABN AMRO Chicago
Corporation with respect to such services was $50,000 and $1,043,298 during 1996
and 1997, respectively. Additionally, ABN AMRO is a co-manager of the Bank
Credit Facility.
 
    RECENT DEVELOPMENTS--ACQUISITION OF DELTA LIFE CORPORATION
 
    General.  On October 23, 1997, AmerUs acquired all of the outstanding
capital stock of Delta for $162.9 million in cash. The principal asset of Delta
is its wholly-owned subsidiary, Delta Life and Annuity Company ("DELTA LIFE"), a
Tennessee domiciled life insurance company formed in 1955. Delta Life
specializes in the sale of individual single and flexible premium deferred
annuities, primarily in the southeastern, western, southwestern and midwestern
regions of the United States. Such sales are made primarily through a network of
over 3,400 independent agents. Approximately 55% of Delta Life's 1996 direct
collected premiums were derived from retirement-oriented tax-qualified
annuities. Delta Life is licensed in the District of Columbia and in all states
except New York.
 
    Delta Life's strategy is to structure its fixed annuity products to appeal
to the conservative retirement saver who is seeking principal preservation and
consistency of earnings. Most of Delta Life's products are innovative in that
they incorporate a fixed contractual management fee. In addition to offering a
lifetime guaranteed minimum interest crediting rate and an annual guaranteed
interest crediting rate, these annuities also require the crediting of the
interest rate earned on the assets supporting the respective policies after
deducting the contractual management fee. Over 70% of policyowners' assets are
invested in securities issued, secured or guaranteed by the U.S. Government,
government agencies or instrumentalities.
 
    AmerUs believes that the acquisition of Delta is an important step in
implementing AmerUs' growth strategy. With this acquisition, AmerUs increases
its presence in the rapidly growing asset accumulation business, gains access to
Delta's extensive marketing capabilities, significantly expands distribution
capacity and gives AmerUs additional scale with the opportunity for improved
operational efficiencies and substantial expense reductions.
 
    Delta Life's operations complement a number of the operating fundamentals of
AmerUs. By integrating the operations of Delta Life with those of AmerUs Life,
management expects to substantially reduce the unit costs of both AmerUs Life's
and Delta Life's general insurance expenses and investment expenses by spreading
fixed costs over a larger revenue base. Delta Life's distribution system of
independent agents continues AmerUs' efforts to increase capacity and diversify
distribution channels. To the extent that Delta Life has built sales in the
south and southeast, this provides geographic diversification in areas where
AmerUs Life has not concentrated its sales activities in the past. At the same
time, the product strategy of Delta Life expands AmerUs' offering of competitive
products that meet the demands of customers.

    Products.  Delta Life's product offerings differ from those of most of its
competitors in two ways. First, Delta Life offers an interest rate crediting
strategy on almost all of its single and flexible premium deferred annuities
that credits the policy with a return based upon the interest rate it earns on
assets supporting the respective policies less a contractually stated management
fee. In addition, these policies offer a lifetime guaranteed minimum interest
crediting rate and an annual guaranteed interest crediting rate. Second, Delta
Life's investment policy mandates that no less than 70% of policyowners' assets
be invested in securities issued, secured or guaranteed by the U.S. Government,
government agencies or instrumentalities. The balance of these funds is invested
primarily in investment grade corporate bonds and commercial mortgages.
 
    In 1996, Delta Life introduced and commenced marketing two single premium
equity index annuity products that are based either on Standard & Poor's 500
Composite Stock Price Index ("S&P 500-Registered Trademark-") or an
international index created by Delta Life from stock market indexes from France,
Germany, Japan, Switzerland and the United Kingdom. These products receive the
benefit of 100% of any increase in the selected index less a contractually
stated management fee. This benefit is determined as follows: On each policy
anniversary, a new S&P 500-Registered Trademark- value is locked in. If this
value is higher than any other prior anniversary value, an annual effective
interest rate is calculated for the seven year term using the S&P
500-Registered Trademark- values at the commencement of the policy and on the
last anniversary. The contractual annual management fee is subtracted and the
resulting net rate is used to calculate the value of the policy at the end of
the seven year term. If a higher S&P 500-Registered Trademark- value occurs on a
later policy anniversary, then this calculation is repeated using the higher S&P
500-Registered Trademark- value. The policyowner is guaranteed to receive at
least 110% of the original premium at the end of the seven year term of the
policy, assuming no withdrawals.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL
  CONDITION OF AMERUS
 
    THE FOLLOWING ANALYSIS OF THE CONSOLIDATED RESULTS OF OPERATIONS AND
FINANCIAL CONDITION OF AMERUS SHOULD BE READ IN CONJUNCTION WITH THE AMERUS
SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA AND THE CONSOLIDATED FINANCIAL
STATEMENTS OF AMERUS AND RELATED NOTES INCLUDED ELSEWHERE IN THIS JOINT PROXY
STATEMENT/PROSPECTUS.
 
      OVERVIEW.  AmerUs is a holding company engaged through its subsidiaries in
the business of marketing, underwriting and distributing a broad range of
individual life insurance and annuity products to individuals and businesses in
49 states and the District of Columbia. AmerUs' primary product offerings
consist of whole life, universal life and term life insurance policies and fixed
annuities. Since April 1, 1996 AmerUs has been a party to the Ameritas Joint
Venture with Ameritas Life Insurance Corp., through which it markets fixed
annuities and sells variable annuities and variable life insurance products. See
"--Business--Products" and "--Business--Ameritas Joint Venture."
 
    In accordance with GAAP, universal life insurance premiums and annuity
deposits received are reflected as increases in liabilities for policyowner
account balances and not as revenues. Revenues reported for universal life and
annuity products consist of policy charges for the cost of insurance,
administration charges and surrender charges assessed against policyowner
account balances. Surrender benefits paid relating to universal life insurance
policies and annuity products are reflected as decreases in liabilities for
policyowner account balances and not as expenses. Amounts for interest credited
to universal life and annuity policyowner account balances and benefit claims in
excess of policyowner account balances are reported as expenses in the financial
statements. AmerUs receives investment income earned from the funds deposited
into account balances by universal life and annuity policyowners, the majority
of which is passed through to such policyowners in the form of interest
credited.
 
    Premium revenues reported for traditional life insurance products are
recognized as revenues when due. Future policy benefits and policy acquisition
costs are recognized as expenses over the life of the policy by means of a
provision for future policy benefits and amortization of deferred policy
acquisition costs.
 
    The costs related to acquiring new business, including certain costs of
issuing policies and certain other variable selling expenses (principally
commissions), defined as deferred policy acquisition costs, are capitalized and
amortized as an expense in proportion to expected profits or margins from such
policies. This amortization is adjusted when current or estimated future gross
profits or margins on the underlying policies vary from previous estimates. For
example, the amortization of deferred policy acquisition costs is accelerated
when policy terminations are higher than originally estimated or when
investments supporting the policies are sold at a gain prior to their
anticipated maturity. Death and other policyowner benefits reflect exposure to
mortality risk and fluctuate from period to period based on the level of claims
incurred within insurance retention limits. The profitability of AmerUs is
primarily affected by expense levels, interest spread results (i.e., the excess
of investment earnings over the interest credited to policyowners) and
fluctuations in mortality, persistency and other policyowner benefits. AmerUs
has the ability to mitigate adverse experience through adjustments to credited
interest rates, policyowner dividends or cost of insurance charges.
 
      ADJUSTED OPERATING INCOME.  The following table reflects net income
adjusted to eliminate certain items (net of applicable income taxes) which
management believes are not necessarily indicative of overall operating trends,
including net realized gains or losses on investments. Different items are
likely to occur in each period presented and others may have different opinions
as to which items may

warrant adjustment. The adjusted operating income shown below does not
constitute net income computed in accordance with GAAP.

- ------------------
 
(A) Represents realized gains or losses on investments less that portion of the
    amortization of deferred policy acquisition costs adjusted for income taxes
    on such amounts. Realized gains may vary widely between periods. Such
    amounts are determined by management's timing of individual transactions and
    do not necessarily correspond to the underlying operating trends.
 
(B) Represents the mutual life insurance company equity add-on tax, which is
    applicable only to mutual life insurance companies and which AmerUs believes
    will not be applicable to AmerUs after June 30, 1996 due to AmerUs Life's
    conversion into a stock company.
 
(C) Represents costs directly related to the AmerUs Reorganization consisting
    primarily of printing, postage, legal and consulting costs. All of the 1995
    costs were incurred in the second half of 1995. These costs were not of a
    continuing nature and were not expected to have any effect on future
    operations.
 
(D) As of January 1, 1993, AmerUs adopted SFAS 106, pursuant to which the cost
    of certain post-retirement benefits must be recognized on an accrual basis
    as employees perform services to earn such benefits. AmerUs' transition
    obligation as of January 1, 1993 amounted to approximately $3.2 million, net
    of income tax benefits, and was recorded as a cumulative effect adjustment
    to net income.
 
       THE CLOSED BLOCK.  In connection with the AmerUs Reorganization, the
Closed Block was established. Insurance policies which had a dividend scale in
effect as of June 30, 1996 were included in the Closed Block. The Closed Block
was designed to provide reasonable assurance to owners of insurance policies
included therein that, after the AmerUs Reorganization, assets would be
available to maintain the dividend scales and interest credits in effect prior
to the AmerUs Reorganization if the experience underlying such scales and
credits continues. See "RISK FACTORS--Risks Relating to the Closed Block" and
"--Business--The AmerUs Reorganization."
 
    The contribution to the operating income of AmerUs from the Closed Block is
reported as a single line item in the income statement. Accordingly, premiums,
product charges, investment income, realized gains (losses) on investments,
policyowner benefits and dividends attributable to the Closed Block, less
certain minor expenses including amortization of deferred policy acquisition
costs, are shown as a net number under the caption the "Contribution from the
Closed Block." This results in material reductions in the respective line items
in the income statement while having no effect on net income. The expenses
associated with the administration of the policies included in the Closed Block
and the renewal commissions on these policies are not charged against the
Contribution from the Closed Block, but rather are grouped with underwriting,
acquisition and insurance expenses. Also, all assets allocated to the Closed
Block are grouped together and shown as a separate item entitled "Closed Block
Assets." Likewise, all liabilities attributable to the Closed Block are combined
and disclosed as the "Closed Block Liabilities."

  AMERUS RESULTS OF OPERATIONS
 
  Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
    COMBINED RESULTS OF OPERATIONS.  Since the operating results from the Closed
Block for the six months ended June 30, 1997 are reported on one line of the
income statement, "Contribution from the Closed Block," the individual income
statement components for the first six months of 1997 are not fully comparable
with those for the first six months of 1996, prior to the establishment of the
Closed Block. Management believes that the presentation of the results of
operations for the six months ended June 30, 1997 on a combined basis as if the
Closed Block had not been formed facilitates comparability with the results of
operations for the six months ended June 30, 1996. Accordingly, the combined
presentation set forth below includes certain revenues and expenses associated
with the policies included in the Closed Block. Such presentation does not,
however, affect AmerUs' reported net income.

    Individual life and annuity premiums and product charges increased $5.4
million, or 3.6%, for the six months ended June 30, 1997 from the same period in
1996. Traditional life insurance premiums increased $4.1 million for the six
months as a result of continued growth in renewal premiums. Immediate annuity
deposits and supplementary contract premiums were $0.3 million higher for the
six months ended June 30, 1997 compared to the same period in 1996. The increase
was primarily the result of higher supplementary contract premiums. Other
premiums were lower in 1997 for the six month period primarily due to the sale
of AmerUs' remaining group life operation in the third quarter of 1996.
 
    Universal life product charges increased $1.0 million for the six months
ended June 30, 1997 compared to the same period in 1996. The increased product
charges in 1997 were primarily due to increased cost of insurance charges as a
result of the normal aging of the block of business.
 
    Net investment income increased $9.9 million for the six months ended June
30, 1997 from the same period in 1996. Average invested assets for the first
half of 1997 increased $152.3 million (excluding market value adjustments) over
the same period in 1996, and the effective yield on average invested assets
(excluding market value adjustments) increased from 7.69% for the first six
months of 1996 to 7.88% for the same period in 1997. Included in the six months
1997 net investment income was $2.6 million from other invested assets and $2.4
million from the sale of certain investment partnership interests.
 
    Realized gains on investments decreased $55.9 million for the six months
ended June 30, 1997 from the same period in 1996. Included in the six month
amounts for 1996 were approximately $52.4 million of gains from the sale of
common stock as a result of the liquidation of AmerUs' equity portfolio, with
approximately $51.5 million of the gains occurring during the first quarter of
1996.

</TABLE>
 
    Total policyowner benefits increased $4.2 million for the six months ended
June 30, 1997 from the same period in 1996. Traditional life insurance benefits
increased $5.5 million for the six month period primarily due to the growth and
aging of the business inforce and increased death benefits as a result of
slightly higher mortality. Universal life insurance benefits increased $4.6
million for the six months ended June 30, 1997 from the same period in 1996
primarily as a result of increased death benefits due to higher mortality.
 
    Interest credited to universal life policyowner account balances increased
$1.6 million for the six months ended June 30, 1997 from the same period in
1996. While the weighted average crediting rate for AmerUs' universal life
liabilities decreased 12 basis points from 6.36% for the first six months of
1996 to 6.24% for the first six months of 1997, AmerUs' average liabilities
increased $34.6 million over the same period, resulting in the increased
credited amounts during the first six months of 1997.
 
    Annuity benefits decreased $4.2 million for the six months ended June 30,
1997 from the same period in 1996 primarily due to reduced interest credited to
policyowner account balances. The decrease in interest credited amounts in 1997
compared to 1996 amounted to $5.2 million for the six months ended June 30. The
weighted average crediting rate for AmerUs' individual deferred annuity
liabilities decreased 13 basis points to 5.38% for the first six months of 1997
compared to 5.51% for the first six months of 1996. AmerUs' average deferred
annuity liabilities decreased $125.7 million from the first six months of 1996
to the first six months of 1997, also contributing to the decrease in interest
credited amounts in 1997. The increase in other annuity benefits in 1997 was
primarily the result of higher supplemental contract premiums.
 
    Miscellaneous benefits were lower in 1997 for the six month period primarily
due to the sale of AmerUs' remaining group life operation in the third quarter
of 1996.

</TABLE>
 
    Commission expense, net of deferrals was $4.1 million for the six months
ended June 30, 1997, decreasing $0.4 million from the same period a year ago
primarily due to lower sales of products for which commissions are not
capitalized. Other underwriting, acquisition and insurance expenses, net of
deferrals, increased $3.2 million for the six months ended June 30, 1997, from
the same period in 1996. The increase in expenses in 1997 for the six month
period is primarily due to interest expense on capital securities issued by
AmerUs and interest expense on the revolving line of credit. This added expense
was largely offset by investment of the borrowed funds which contributed to the
growth in invested assets and the higher investment earnings.
 
    The amortization of deferred policy acquisition costs decreased $4.1 million
for the six months ended June 30, 1997, from the same period in 1996. Deferred
policy acquisition costs are generally amortized in proportion to gross margins,
including realized capital gains. Higher death benefits and lower realized
capital gains in the first six months of 1997, compared to the first six months
of 1996, contributed to lower gross margins in 1997 on products for which
deferred costs are amortized, resulting in the lower amortization during the
first six months of 1997.
 
    Dividends to policyowners increased $3.4 million for the six months ended
June 30, 1997 from the same period in 1996. The increase in the dividends for
the six month period was the result of the growth and aging of the inforce
policies and the establishment of a deferred dividend liability for the Closed
Block, as actual gross profits on such policies through June 30, 1997, exceeded
expected profits. Traditional life reserves grew 7.9% from June 30, 1996, to
$1.26 billion at June 30, 1997. The weighted average interest rate used in the
dividend formula for these policies was 7.18% during the first six months of
1997 compared to 7.17% during the same period of 1996.
 
    Income before income tax expense and equity in earnings of unconsolidated
subsidiary decreased $49.1 million for the six months ended June 30, 1997 to
$39.9 million compared to $89.0 million for the same period for 1996, due
primarily to lower realized gains on investments in 1997.
 
    Income tax expense decreased $21.2 million for the six months ended June 30,
1997 from the same period in 1996 primarily as a result of the lower pre-tax
income due to the lower realized gains on investments, and as a result of the
$4.5 million provision for the equity add-on tax in the first half of 1996.
 
    Net income decreased $27.5 million for the six months ended June 30, 1997
from the same period in 1996. The reduced net income for the six month period
resulted primarily from lower realized gains on investments.
 
  1996 Compared to 1995
 
    COMBINED RESULTS OF OPERATIONS.  Since the operating results from the Closed
Block for the six months ended December 1996 are reported on one line of the
income statement, "Contribution from the Closed Block," individual income
statement components for 1996 are not fully comparable with those for 1995 and
1994, prior to the establishment of the Closed Block. Management believes that
the presentation of the results of operations for 1996 on a combined basis as if
the Closed Block had not been formed facilitates comparability with the results
of operations for 1995 and 1994. Accordingly, the
 
                                      142

combined presentation set forth below includes certain revenues and expenses
associated with policies included in the Closed Block. Such presentation does
not, however, affect AmerUs' reported net income.

    Individual life and annuity premiums and product charges increased $9.0
million to $303.8 million, or 3.1%, from $294.8 million in 1995. Insurance
premiums increased $2.7 million to $246.8 million in 1996 compared to $244.1
million in 1995. Traditional life insurance premiums increased $9.3 million in

1996. While there have been modest decreases in new traditional life insurance
production over the past two years, continued growth in renewal premiums has
produced the increase in traditional life insurance premiums in 1996. Immediate
annuity deposits and supplementary contract premiums were $1.6 million lower in
1996 compared to 1995 due to reduced immediate annuity sales. Other premiums
decreased significantly in 1996 primarily due to AmerUs' exit from several group
life and long-term disability reinsurance pools in the second half of 1995 and
the sale of AmerUs' remaining group life operation in the third quarter of 1996.
 
    Universal life product charges increased slightly in 1996 primarily due to
increased cost of insurance charges as a result of the normal aging of that
block of business.
 
    Net investment income decreased by $0.3 million to $284.9 million in 1996
compared to $285.2 million in 1995. The decrease in net investment income in
1996 was attributable to an increase in average invested assets more than offset
by declines in the effective yields on average invested assets. Average invested
assets (excluding market value adjustments) increased by $171.8 million to
$3,790.1 million in 1996, compared to $3,618.3 million in 1995. The increase in
average invested assets in 1996 was largely attributable to the investment of
the $175.0 million proceeds from bank borrowings late during the year. The
effective yield on average invested assets (excluding market value adjustments)
decreased to 7.52% in 1996 from 7.88% in 1995. The decrease in effective yield
in 1996 was primarily due to lower bond yields and the timing of the investment
of the proceeds from the bank borrowing.
 
    Realized gains on investments were $66.4 million in 1996 compared to gains
of $51.4 million in 1995. The increase in gains of $15.0 million in 1996
resulted primarily from increased sales of common stock in the investment
portfolio. The sale of common stock in 1996 was a direct result of AmerUs'
decision to reduce the level of equity securities as a percentage of its
investment portfolio on a long-term basis. Proceeds from these sales were
invested primarily in fixed maturity securities.
 
    Other revenues decreased $2.7 million in 1996 to $2.7 million compared to
$5.4 million in 1995. Other revenues in 1995 included a gain of $3.1 million
which resulted from the curtailment of AmerUs' defined benefit pension plans
effective December 31, 1995. Effective January 1, 1996, such defined benefit
pension plans were replaced with a defined contribution savings retirement plan.

<PAGE>
    Total policyowner benefits were $365.8 million in 1996 compared to $374.6
million in 1995. Traditional life insurance benefits increased by $7.3 million
in 1996 primarily due to the growth in the amount of such business inforce.
Universal life insurance benefits increased by $2.5 million in 1996. The
increased benefits in 1996 were due to increased death benefits due to higher
mortality and increased interest credited to policyowner account balances. While
the weighted average crediting rate for AmerUs' universal life liabilities
decreased 19 basis points to 6.27% in 1996 from 6.46% in 1995, AmerUs' average
liabilities increased $39.8 million from 1995 to 1996, resulting in the
increased credited amounts in 1996.
 
    Annuity benefits decreased $13.1 million in 1996 to $100.6 million compared
to $113.7 million in 1995. Such benefits decreased in 1996 primarily due to
reduced interest credited to policyowner account balances. The weighted average
crediting rate for AmerUs' individual deferred annuity liabilities decreased 80
basis points to 5.36% in 1996 compared to 6.16% in 1995 and AmerUs' average
deferred annuity liabilities decreased $71.0 million from 1995 to 1996, also
contributing to the lower interest credited amounts in 1996.
 
    Miscellaneous benefits decreased significantly in 1996 primarily due to
AmerUs' exit from several group life and long-term disability reinsurance pools
in the second half of 1995 and the sale of AmerUs' remaining group life
operation in the third quarter of 1996.

</TABLE>
 
    Commission expense, net of deferrals, decreased $2.5 million to $7.9 million
in 1996 compared to $10.4 million in 1995. The reduction in 1996 was primarily
due to a decrease in gross commission expense as a result of lower life
insurance sales in 1996 and the transfer of new annuity sales to the Ameritas
Joint Venture in May 1996. Other underwriting, acquisition and insurance
expenses, net of deferrals, increased by $6.6 million, or 13.7%, to $54.8
million in 1996. The increase in expenses during 1996 was due to increased costs
related to the AmerUs Reorganization of $0.1 million, the formation of the
Ameritas Joint Venture of $0.4 million, and expenses related to changing the
name of the life company to AmerUs Life of $0.7 million; higher premium taxes of
$1.1 million due to a one-time adjustment to the amortization of the guaranty
association asset and an increased accrual for estimated future assessments; and
increased settlements and associated legal fees of $4.7 million. 1996
settlements and legal fees included the establishment of a $5.0 million reserve
in connection with certain pending class action litigation.
 
    The amortization of deferred policy acquisition costs increased by $8.3
million in 1996. Since deferred policy acquisition costs are primarily amortized
in proportion to gross margins, the increases in amortization in 1996 are
primarily due to higher gross margins including increased realized capital
gains.
 
    Dividends to policyowners increased by $6.1 million, or 12.3%, to $55.5
million in 1996 compared to $49.4 million in 1995. The increase in dividends was
primarily the result of the growth and aging of inforce business. Traditional
life reserves grew 7.7% from the end of 1995 to the end of 1996, or to $1.21
billion. The weighted average dividend rate credited to these policies was 7.17%
in 1996 compared to 7.14% in 1995.

    Income before income tax expense and equity in earnings of unconsolidated
subsidiary increased by $6.5 million to $117.0 million in 1996 compared to
$110.5 million in 1995. The increase in 1996 resulted primarily from the
increase in realized gains on investments.
 
    Income tax expense increased $2.6 million in 1996 to $43.8 million compared
to $41.2 million in 1995. The increased 1996 income taxes were the result of the
higher pre-tax income due primarily to the increased realized gains on
investments and a $4.5 million provision for the equity add-on tax in the first
half of 1996, partially offset by $2.7 million of low-income housing tax
credits. The equity add-on tax is applicable only to mutual life insurance
companies and AmerUs believes such tax will not be applicable to AmerUs after
June 30, 1996 due to AmerUs Life's conversion into a stock company.
 
    Net income increased by $4.9 million in 1996 to $74.2 million compared to
$69.3 million in 1995. The increased net income in 1996 resulted largely from
the higher pre-tax income due primarily to the increased realized gains on
investments.

    Individual life and annuity premiums and product charges increased $12.3
million to $294.8 million, or 4.4%, from $282.5 million in 1994. Insurance
premiums increased $6.2 million to $244.1 million in 1995 compared to $237.9
million in 1994. Traditional life insurance premiums increased $10.3 million
primarily as a result of continued growth in renewal premiums. Immediate annuity
deposits and supplementary contract premiums were $1.0 million greater in 1995
than 1994 due to increased immediate annuity sales. Other premiums were $5.1
million lower in 1995 than in 1994 primarily due to AmerUs' exit from several
group life and long-term disability reinsurance pools in 1995, as part of
management's continuing review of insurance products' profitability.
 
    Universal life product charges were $0.9 million higher in 1995 compared to
1994 primarily due to increased cost of insurance charges as a result of the
normal aging of that block of business.
 
    Net investment income increased by $9.5 million, or 3.5%, to $285.2 million
in 1995 as compared to $275.7 million in 1994. The increase was attributable to
an increase in average invested assets partially offset by a decline in the
effective yield on average invested assets. Average invested assets (excluding
market value adjustments) increased by $156.1 million in 1995 to $3,618.3
million compared to $3,462.2 million in 1994. The effective yield on average
invested assets (excluding market value adjustments) decreased from 7.96% in
1994 to 7.88% in 1995 reflecting a reduction in interest income on both bonds
and commercial mortgages as a result of lower market interest rates on new
investments.
 
    Realized gains on investments were $51.4 million in 1995 compared to
realized losses of $19.9 million in 1994. The increase of $71.3 million in 1995
resulted primarily from the combination of increased
 
                                      146
<PAGE>
gains of $32.5 million over 1994 amounts from the sale of common stock and a
gain of $9.4 million in 1995 compared to a loss of $25.5 million in 1994 from
sales of fixed maturity securities. Of the losses incurred in 1994, $21.1
million were incurred in connection with sales of fixed maturity securities
which resulted from a planned investment strategy that maximized the after-tax
proceeds from the sale of selected fixed maturity securities. The sales of
common stock in 1995 were a direct result of AmerUs' decision to reduce the
level of equity securities as a percentage of its investment portfolio on a
long-term basis. Proceeds from these sales were invested primarily in fixed
maturity securities.
 
    Other revenues increased in 1995 by $3.0 million from 1994 levels, primarily
due to a gain of $3.1 million which resulted from the curtailment of AmerUs'
defined benefit pension plans, effective December 31, 1995. See Note 7 to the
Consolidated Financial Statements of AmerUs.

</TABLE>
 
    Total policyowner benefits increased $4.7 million from 1994 to $374.6
million in 1995. Traditional life benefits increased $5.6 million due to
increased mortality costs and increased liabilities for future policy benefits,
in each case primarily associated with the growth in the amount of such business
inforce. Universal life benefits increased $3.1 million primarily due to
increased interest credited to policyowner account balances. The weighted
average crediting rate for AmerUs' universal life liabilities increased two
basis points from 6.44% in 1994 to 6.46% in 1995, and AmerUs' average
liabilities increased $41.9 million, or 5.8%, from 1994 to 1995, resulting in
the increased credited amounts in 1995.
 
    Annuity benefits increased $0.8 million in 1995 to $113.7 million compared
to $112.9 million in 1994. Such benefits increased due to increased interest
credited to policyowner account balances and increased other annuity benefits.
While the weighted average crediting rate for AmerUs' individual deferred
annuity liabilities decreased 25 basis points to 6.16% in 1995 compared to 6.41%
in 1994, AmerUs' average liabilities increased $32.1 million, or 2.5%, from 1994
to 1995, resulting in the increased interest credited amounts in 1995. The
increased other annuity benefits were the result of continued growth in the
immediate annuity and supplementary contract business inforce.
 
    The decrease in miscellaneous benefits of $4.8 million to $8.4 million in
1995 compared to $13.2 million in 1994 was primarily the result of AmerUs' exit
from several group life and long-term disability reinsurance pools in 1995.

</TABLE>
 
    Commission expense, net of deferrals, increased $1.0 million, or 10.5%, in
1995 to $10.4 million, primarily as a result of the integration of the product
lines of Central Life and Old AML and an increase in gross commissions of $3.0
million as a result of increased annuity sales in 1995. Other underwriting,
acquisition and insurance expenses, net of deferrals, decreased in 1995 by $10.9
million, or 18.5%, to $48.2 million. 1995 was the first year of the consolidated
operations of Central Life and Old AML. As a result of the combination,
approximately $7.8 million of cost reductions were realized in 1995 from 1994
combined levels, excluding the merger-related expenses described below. These
reductions in 1995 were partially offset by increased legal and settlement costs
of $1.1 million, higher incentive compensation of $1.0 million and $2.2 million
of expenses related to the investigation and review of alternative capital
structures, including implementing the AmerUs Reorganization. Included in 1994
expenses were approximately $10.0 million of expenses related to the merger of
Central Life and Old AML compared to $2.2 million of merger-related costs in
1995.
 
    The amortization of deferred policy acquisition costs increased by $7.4
million to $50.2 million in 1995 compared to $42.8 million in 1994. The increase
in amortization in 1995 was primarily due to higher realized gains and gross
margins in 1995 than in 1994.
 
    Dividends to policyowners increased by $4.4 million, or 9.8%, to $49.4
million in 1995 compared to $45.0 million in 1994. The growth in dividends was
primarily the result of the growth and aging of the inforce policies.
Traditional life reserves grew 8.4% from 1994 to $1.12 billion in 1995. The
weighted average dividend rate credited to these policies was 7.14% for 1995 and
1994.
 
    Income before income tax expense and equity in earnings of unconsolidated
subsidiary increased by $84.4 million, or 323%, to $110.5 million in 1995
compared to $26.1 million in 1994. The increase resulted primarily from the $9.5
million increase in net investment income, net realized gains on investments of
$51.4 million in 1995 as compared to net realized losses on investments of $19.9
million in 1994, and reduced expenses, partially offset by higher dividends to
policyowners.
 
    Income tax expense increased by $21.8 million to $41.2 million in 1995 as
compared to $19.4 million in 1994. The increased 1995 income taxes were the
result of the higher pre-tax income discussed above. The effective income tax
rate for 1995 was 37.3% and for 1994 was 74.5%. In 1994, American Mutual Life
was subject to the equity add-on tax which resulted in an additional $9.6
million of current income tax expense. The effective income tax rate for 1994,
adjusted to remove the equity add-on tax, would have been 37.8%. The 1995 equity
add-on tax was zero.
 
    Net income increased by $62.6 million in 1995 to $69.3 million from $6.7
million in 1994. This increase resulted from the increases in pre-tax income
discussed above.
 
  LIQUIDITY AND CAPITAL RESOURCES
 
    AmerUs. AmerUs' cash flows from operations consist of dividends from
subsidiaries, if declared and paid, interest income on loans and advances to its
subsidiaries (including a surplus note issued to AmerUs by AmerUs Life),
investment income on assets held by AmerUs and fees which AmerUs charges AmerUs
Group, AmerUs Life, Delta and certain other of its affiliates for management
services, offset by the expenses incurred for debt service, salaries and other
expenses.
 
                                      148

    AmerUs intends to rely primarily on dividends and interest income from
AmerUs Life and Delta in order to make dividend payments to its shareholders.
The payment of dividends by AmerUs Life to AmerUs is regulated under Iowa law.
Under Iowa law, AmerUs Life may pay dividends only from the earned surplus
arising from its business and must receive the prior approval of the Iowa
Commissioner to pay a dividend if such dividend would exceed certain statutory
limitations. The current statutory limitation is the greater of (i) 10% of
AmerUs Life's capital and surplus as of the preceding year end or (ii) the net
gain from operations for the previous calendar year. Iowa law gives the Iowa
Commissioner broad discretion to disapprove requests for dividends in excess of
these limits. Based on this limitation and 1996 statutory results, and absent
the AmerUs Reorganization, AmerUs Life would have been able to pay approximately
$34 million in dividends without obtaining the Iowa Commissioner's approval.
However, as a result of the AmerUs Reorganization, AmerUs Life is not able to
pay dividends to AmerUs until December 1997 without the prior approval of the
Iowa Commissioner. Thus far in 1997, AmerUs Life has requested and received
approval to pay $10 million of dividends. See "--Business--Supervision and
Regulation." It is AmerUs Life's intention to seek regulatory approval to pay
additional dividends to AmerUs during 1997. The payment of dividends by Delta to
AmerUs is regulated under Tennessee law, which has statutory limitations similar
to Iowa's. Based on these limitations and 1996 statutory results, Delta could
pay $8.7 million in dividends in 1997. Management believes that AmerUs will have
adequate access to capital through the public equity and debt markets and the
Bank Credit Facility to meet presently anticipated capital requirements.
 
    On October 23, 1997, AmerUs entered into a $250 million revolving credit
facility with a syndicate of lenders (the "BANK CREDIT FACILITY") to be used to
replace its existing revolving credit facility, to finance the acquisition of
Delta, to finance permitted mergers and acquisitions and to finance other
general corporate purposes. The Bank Credit Facility is secured by a pledge of
approximately 49.9% of the outstanding common stock of AmerUs Life, 100% of the
outstanding common stock of Delta and a $50 million 9% surplus note payable to
AmerUs by AmerUs Life. As of October 31, 1997, there was an outstanding loan
balance of $235.1 million under the facility. The Bank Credit Facility provides
for typical events of default and covenants with respect to the conduct of the
business of AmerUs and its subsidiaries and requires the maintenance of various
financial levels and ratios. Among other covenants, AmerUs (a) cannot have a
leverage ratio greater than 0.35:1.0 or an interest coverage ratio less than
2.5:1.0, (b) is prohibited from paying cash dividends on its common stock in
excess of an amount equal to 3% of its consolidated net worth as of the last day
of the preceding fiscal year, and (c) must cause certain of its subsidiaries
including AmerUs and Delta Life to maintain certain ratings from A.M. Best and
certain levels of adjusted capital and surplus and risk-based capital.
 
    AmerUs may also be affected by the restrictions under the existing credit
agreement of AmerUs Group described above (see "--Business--Certain Transactions
and Relationships--Restrictions under AmerUs Group Financing").
 
    Following consummation of the Merger, AmerUs management currently expects
AmerUs to issue approximately $200 million in debt securities. It is currently
anticipated that the proceeds would be used to pay down indebtedness under the
Bank Credit Facility and the amount available under the facility would be
reduced to $150 million.
 
    AmerUs may from time to time review other potential acquisition
opportunities. AmerUs anticipates that funding for any such acquisition may be
provided from available cash resources or from debt or equity financing. In the
future AmerUs anticipates that its liquidity and capital needs will be met
through interest and dividends from its life insurance subsidiaries, accessing
the public equity and debt markets depending upon market conditions, or
alternatively from bank financing.
 
    Life Insurance Subsidiaries.  The cash inflows of AmerUs' life insurance
subsidiaries consist primarily of premium income, deposits to policyowner
account balances, income from investments, sales, maturities and calls of
investments and repayments of investment principal. Cash outflows are primarily
related to withdrawals of policyowner account balances, investment purchases,
payment of policy acquisition costs, payment of policyowner benefits, income
taxes and current operating expenses. Life
 
                                      149
<PAGE>
insurance companies generally produce a positive cash flow from operations, as
measured by the amount by which cash inflows are adequate to meet benefit
obligations to policyowners and normal operating expenses as they are incurred.
The remaining cash flow is generally used to increase the asset base to provide
funds to meet the need for future policy benefit payments and for writing new
business.
 
    Management anticipates that funds to meet its short-term and long-term
capital expenditures, cash dividends to shareholders and operating cash needs
will come from existing capital and internally generated funds. Management
believes that the current level of cash and available-for-sale and short-term
securities, combined with expected net cash inflows from operations, maturities
of fixed maturity investments, principal payments on mortgage-backed securities
and its insurance products, will be adequate to meet the anticipated short-term
cash obligations of AmerUs' life insurance subsidiaries.
 
    AmerUs generated cash flows from operating activities of $106.3 million,
$147.6 million, $189.1 million and $172.4 million for the six months ended June
30, 1997 and for the years ended December 31, 1996, 1995 and 1994, respectively.
Excess operating cash flows were primarily used to increase AmerUs' fixed
maturity investment portfolio consistent with the long-term investment objective
of AmerUs to reduce the level of equity investments and mortgages as a
percentage of its investment portfolio.
 
    Delta generated cash flows (deficits) from operating activities of $5.6
million, $7.9 million, $(5.8) million and $1.3 million for the six months ended
June 30, 1997 and for the years ended December 31, 1996, 1995 and 1994,
respectively. Excess operating cash flows were primarily used to increase
Delta's fixed maturity investment portfolio.
 
    Matching the investment portfolio maturities to the cash flow demands of the
type of insurance being provided is an important consideration for each type of
life insurance product and annuity. AmerUs continuously monitors benefits and
surrenders to provide projections of future cash requirements. As part of this
monitoring process, AmerUs performs cash flow testing of its assets and
liabilities under various scenarios to evaluate the adequacy of reserves. In
developing its investment strategy, AmerUs establishes a level of cash and
securities which, combined with expected net cash inflows from operations,
maturities of fixed maturity investments and principal payments on
mortgage-backed securities, are believed adequate to meet anticipated short-term
and long-term benefit and expense payment obligations. There can be no assurance
that future experience regarding benefits and surrenders will be similar to
historic experience since withdrawal and surrender levels are influenced by such
factors as the interest rate environment and the claims-paying and financial
strength ratings of AmerUs' life insurance subsidiaries. See "RISK
FACTORS--Future Policy Benefits Exposure" and "--Interest Rate Fluctuations;
Risk of Impact on Forced Liquidation of Investment Portfolio."
 
    AmerUs takes into account asset-liability management considerations.
Contract terms for AmerUs' interest-sensitive products include surrender and
withdrawal provisions which mitigate the risk of losses due to early
withdrawals. These provisions generally do one or more of the following: limit
the amount of penalty-free withdrawals, limit the circumstances under which
withdrawals are permitted, or assess a surrender charge or market value
adjustment relating to the underlying assets. The following table summarizes
statutory liabilities for interest-sensitive life products and annuities by
their contractual withdrawal provisions at June 30, 1997 (dollars in millions):

    Through its membership in the Federal Home Loan Bank of Des Moines, AmerUs
Life is eligible to borrow on a line of credit available to provide it
additional liquidity. The line of credit, the amount of which is re-set
annually, is based on the amount of capital stock of the Federal Home Loan Bank
of Des Moines owned by AmerUs Life, which supported a borrowing capacity of
$33.4 million as of June 30, 1997. Interest is payable at a current rate at the
time of any advance. As of June 30, 1997, AmerUs Life had a $25 million open
secured line of credit against which $19.9 million had been borrowed.
 
    AmerUs' life insurance subsidiaries may also obtain liquidity through sales
of investments or borrowings collateralized by their investment portfolios.
AmerUs' investment portfolio as of June 30, 1997 had a carrying value of $4.0
billion, including Closed Block investments. As of June 30, 1997, fixed maturity
securities were $3.4 billion, or 83.7% of invested assets, with public and
private fixed maturity securities constituting $3.0 billion, or 75.5%, and
$326.8 million, or 8.2%, of total fixed maturity securities, respectively. See
"--Business--Investment Portfolio." Delta's investment portfolio as of June 30,
1997 had a carrying value of $1.8 billion.
 
    At June 30, 1997, the statutory surplus of AmerUs Life and Delta Life was
approximately $295 million and $88.5 million, respectively. AmerUs believes that
these levels of statutory capital are more than adequate as each life insurance
subsidiary's risk-based capital is significantly in excess of required levels.
See "--Business--Supervision and Regulation--Regulation of Life Insurance
Subsidiaries."
 
    In the future, in addition to their cash flows from operations and borrowing
capacity, the life insurance subsidiaries would anticipate obtaining their
required capital from AmerUs as AmerUs will have access to the public debt and
equity markets.
 
    EFFECTS OF INFLATION AND INTEREST RATE CHANGES.  AmerUs does not believe
that inflation has had a material effect on its consolidated results of
operations.
 
    Interest rate changes may have temporary effects on the sale and
profitability of the annuities and life insurance products offered by AmerUs.
For example, if interest rates rise, competing investments (such as annuities or
life insurance products offered by AmerUs' competitors, certificates of deposit,
mutual funds, and similar instruments) may become more attractive to potential
purchasers of AmerUs' products until AmerUs increases the interest rate credited
to owners of its annuities and life insurance products. In contrast, as interest
rates fall, AmerUs attempts to adjust its credited rates to compensate for the
corresponding decline in reinvestment rates. AmerUs monitors interest rates and
sells annuities and life insurance policies that permit flexible responses to
interest rate changes as part of AmerUs' management of interest spreads.
However, the profitability of AmerUs' products is not based solely upon interest
rate spreads but also on persistency, mortality and expenses.
 
    AmerUs manages its investment portfolio in part to reduce its exposure to
interest rate fluctuations. In general, the market value of AmerUs' fixed
maturity portfolio increases or decreases in an inverse relationship with
fluctuations in interest rates, and AmerUs' net investment income increases or
decreases in a direct relationship with interest rate changes.
 
    Although all of its assets support all of its liabilities, AmerUs has
developed an asset/liability management approach with separate investment
portfolios for major product lines such as traditional life, universal life and
annuities. Investment policies and strategies have been established based on the
specific characteristics of each product line. The portfolio investment policies
and strategies establish asset duration, quality and other guidelines. AmerUs
utilizes analytical systems to establish an optimal asset mix for each line of
business. AmerUs seeks to manage the asset/liability mismatch and the associated
interest rate risk through active management of the investment portfolio.
Financial, actuarial, investment, product development and product marketing
professionals work together throughout the product development, introduction and
management phases to jointly develop and implement product features, initial and
renewal crediting strategies, and investment strategies based on extensive
modeling of a variety of factors under a number of interest rate scenarios.
 
    Inforce reserves and the assets allocated to each segment are modeled on a
regular basis to analyze projected cash flows under a variety of economic
scenarios. The result of this modeling is used
 
                                      151
<PAGE>
to modify asset allocation, investment portfolio duration and convexity and
renewal crediting strategies. AmerUs does invest in collateralized mortgage
obligations as part of its basic portfolio strategy, but uses other types of
derivatives only as a hedge against the effects of interest rate fluctuations or
to synthetically alter the investment characteristics of specific assets. For a
further discussion and disclosure of the nature and extent of AmerUs' use of
derivatives, see Note 13 to the Consolidated Financial Statements of AmerUs.
 
    FEDERAL INCOME TAX MATTERS.  Until February 3, 1997, AmerUs and its
subsidiaries filed as part of a consolidated United States federal income tax
return with AMHC and its subsidiaries. For the short tax year beginning February
4, 1997, AmerUs and its subsidiaries will not file as part of a consolidated
United States federal income tax return with AMHC. Further, AmerUs and its
subsidiaries (including AmerUs Life and Delta) would not be eligible to file a
consolidated life/non-life United States federal income tax return until January
1, 2003, subject to the other requirements of federal income tax law relating to
consolidation.
 
  EMERGING ACCOUNTING MATTERS.
 
    SFAS Nos. 125 and 127.  In June 1996, the FASB issued Statement No. 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities." SFAS No. 125 provides consistent accounting standards for
securitizations and other transfers of assets, determines when financial assets
or liabilities should be considered sold or settled and removed from the balance
sheet, and determines when related revenues and expenses should be recognized.
FASB Statement No. 125 is effective for transfers and servicing of financial
assets and extinguishments of liabilities occurring after December 31, 1996. In
December 1996, the FASB issued Statement No. 127, "Deferral of the Effective
Date of Certain Provisions of FASB Statement No. 125, an Amendment of FASB
Statement No. 125." SFAS No. 127 defers the provisions of SFAS No. 125 for one
year related to repurchase agreements, dollar-rolls, securities lending, and
similar transactions. SFAS No. 125 and 127 are applicable to AmerUs. However,
management believes they will have no material effect on AmerUs' consolidated
financial statements.
 
    SFAS No. 128.  In February 1997, the FASB issued Statement No. 128,
"Earnings Per Share." SFAS No. 128 specifies the computation, presentation, and
disclosure requirements for earnings per share for entities with publicly held
common stock. Basic earnings per share is computed by dividing income available
to common stockholders by the weighted-average number of common shares
outstanding for the period. Diluted earnings per share reflects the dilution
that would occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the entity. SFAS No. 128 is effective
for interim and annual periods ending after December 15, 1997. All prior period
earnings per share data presented will be restated for the provisions of SFAS
No. 128.
 
    SFAS No. 129.  In February 1997, the FASB issued Statement No. 129,
"Disclosure of Information about Capital Structure." SFAS No. 129 requires
disclosures about capital structures, including pertinent rights and privileges
of various securities outstanding; the number of shares issued upon conversion,
exercise, or satisfaction of required conditions during the most recent fiscal
period; the aggregate liquidation preference in involuntary liquidation for
preferred stock or other senior stock; the aggregate per-share amounts at which
preferred stock may be called or is subject to redemption; and the amount of
redemption requirements for all issues of capital stock that are redeemable at
fixed or determinable prices on fixed or determinable dates in each of the five
years following the latest balance sheet presented. SFAS No. 129 is effective
for financial statements for periods ending after December 15, 1997. The
provisions of SFAS No. 129 are of a reporting nature and are not expected to
have an impact on the financial position or results of operations of AmerUs.
 
    SFAS No. 130.  In June 1997, the FASB issued Statement No. 130, "Reporting
Comprehensive Income." SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components: revenues, expenses, gains,
and losses. All items that are required to be recognized under accounting
standards as components of comprehensive income, consisting of changes in equity
 
                                      152
<PAGE>
of a business enterprise during a period from transactions and other events and
circumstances from nonowner sources, are to be reported in a financial statement
that is displayed with the same prominence as other financial statements. SFAS
No. 130 is effective for financial statements beginning after December 15, 1997.
The provisions of SFAS No. 130 are of a reporting nature and are not expected to
have an impact on the financial position or results of operations of AmerUs.
 
    SFAS No. 131.  In June 1997, the FASB issued Statement No. 131, "Disclosures
about Segments of an Enterprise and Related Information." SFAS No. 131
establishes standards for the way that public businesses report information
about operating segments in financial statements. Operating segments are
components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and assess performance. Generally, financial
information is required to be reported on the basis that it is used internally
for evaluating segment performance and deciding how to allocate resources to
segments. SFAS No. 131 is effective for financial statements for periods
beginning after December 15, 1997. The provisions of SFAS No. 131 are of a
reporting nature and are not expected to have an impact on the financial
position or results of operations of AmerUs.
 
    Statutory Accounting Codification.  The NAIC currently is in the process of
codifying statutory accounting practices, the result of which is expected to
constitute the only source of "prescribed" statutory accounting practices.
Accordingly, that project, which is not expected to be effective before the end
of 1999, will likely change certain statutory accounting practices. The
codification may result in changes to the permitted or prescribed accounting
practices that AmerUs' insurance subsidiaries use to prepare their
statutory-basis financial statements.
 
    YEAR 2000 COMPLIANCE.  As the year 2000 approaches, an important business
issue has emerged regarding how existing application software programs and
operating systems can accommodate the date value "2000." Many existing
application software products were designed to only accommodate a two digit date
position which represents the year (E.G., the number "95" is stored on the
system and represents the year 1995). As a result, the year 1999 (i.e., "99") is
the maximum date value many systems will be able to accurately process. AmerUs
has formed a year 2000 working group to address potential problems posed by this
development to assure that AmerUs is prepared for the year 2000. Management does
not anticipate that AmerUs will incur significant operating expenses or be
required to invest heavily in computer system improvements to address the year
2000 issues. However, if modifications and conversions to deal with year 2000
issues are not completed on a timely basis or are not fully effective, such
issues may have a material adverse effect on the operations of AmerUs. All costs
associated with year 2000 modifications and conversions will be expensed as
incurred.

  COMPENSATION PURSUANT TO STOCK PLANS OF AMERUS
 
    STOCK INCENTIVE PLAN.  On September 15, 1996, AmerUs' Board adopted the
AmerUs Life Holdings, Inc. Stock Incentive Plan (the "STOCK PLAN"). The AmerUs
Stock Plan was approved by AmerUs' sole shareholder and became effective on
December 4, 1996. The purpose of the Stock Plan is to enable AmerUs to attract
and retain employees who will contribute to AmerUs' long-term success by
enabling such employees to participate in the long-term success and growth of
AmerUs through an equity interest in AmerUs.
 
    The AmerUs Stock Plan provides for the grant of options (including incentive
stock options and non-qualified stock options), stock appreciation rights and
restricted stock awards.
 
    The summary of the AmerUs Stock Plan which appears below is qualified in its
entirety by reference to the full text of such Plan.
 
    TYPES OF AWARDS.  The AmerUs Stock Plan provides for the grant of any or all
of the following types of awards: (1) stock options, including incentive stock
options and non-qualified stock options; (2) stock appreciation rights; and (3)
restricted stock. Awards may be granted in combination as determined by the
Human Resources Committees of the AmerUs Board (the "COMMITTEE").
 
    TERM.  The AmerUs Stock Plan will terminate ten years after its effective
date (the "TERMINATION DATE"). No awards shall be granted pursuant to the AmerUs
Stock Plan after the Termination Date, but awards granted prior thereto may
extend beyond such time. The AmerUs Board may terminate the AmerUs Stock Plan
prior to the Termination Date; however, termination of the AmerUs Stock Plan
will not affect awards made prior to termination.
 
    ELIGIBILITY.  Officers and other key and high potential employees of AmerUs,
its affiliates and its subsidiaries (but excluding members of the Committee and
any person who serves only as a director) who are responsible for or contribute
to the management, growth and/or profitability of the business of AmerUs are
eligible to be granted stock options, stock appreciation rights, or restricted
stock awards. The options and participants under the AmerUs Stock Plan are
selected from time to time by the Committee, in its sole discretion, from among
those eligible, and the Committee determines, in its sole discretion, the number
of shares covered by each award or grant.
 
    SHARES SUBJECT TO THE STOCK PLAN.  The total number of shares of AmerUs
Class A Common Stock reserved and available for distribution under the AmerUs
Stock Plan is 1.4 million. Such shares may consist, in whole or in part, of
authorized and unissued shares or treasury shares. If any shares of AmerUs Class
A Common Stock that have been optioned cease to be subject to option, or if any
shares subject to Restricted Stock Award granted thereunder are forfeited or
such awards otherwise terminate, such shares shall again be available for
distribution in connection with future awards under the AmerUs Stock Plan. The
maximum total number of shares subject to awards which may be granted under the
AmerUs Stock Plan in any one year is 700,000, and the maximum number of shares
subject to awards which may be granted under the Stock Plan to any individual in
any one year is 230,000 (in both cases, subject to appropriate adjustments to
reflect changes in the capitalization of AmerUs).
 
    STOCK OPTIONS.  The Committee is authorized to determine the terms and
conditions of all option grants, subject to the limitations that the option
price per share may not be less than the fair market value of a share of AmerUs'
common stock on the date of grant and the term of an option may not be longer
than ten (10) years. Payment of the option price may be made in any manner
specified by the Committee (which may include cash or common stock of AmerUs, or
by "cashless exercise").
 
    STOCK APPRECIATION RIGHTS ("SARS").  The Committee is authorized to grant
SARs in tandem with options under the AmerUs Stock Plan. A SAR can be exercised
only to the extent the option with respect to which it is granted is not
exercised, and is subject to the same terms and conditions as the option to
which it relates. Upon exercise of a SAR, the holder will be entitled to
receive, for each share with respect to which the SAR is exercised, an amount
(the "APPRECIATION") equal to the difference between the option
 
                                      155
<PAGE>
price of the related option and the fair market value of a share of common stock
of AmerUs on the date of exercise of the SAR. The appreciation will be payable
in cash or AmerUs Class A Common Stock, at the discretion of the Committee.
 
    RESTRICTED STOCK.  The Committee is authorized to award restricted stock
under the AmerUs Stock Plan subject to the terms and conditions as the Committee
may determine. The Committee has the authority to determine the number of shares
of restricted stock to be awarded, the price, if any, to be paid by the
recipient of the restricted stock, and the date or dates on which the restricted
stock will vest. The vesting of restricted stock may be conditioned upon the
completion of a specific period of service with AmerUs, upon the attainment of
specified performance goals, or upon such other criteria as the Committee may
determine. The AmerUs Stock Plan gives the Committee discretion to make loans to
the recipients for the purchase price of restricted stock and to accelerate the
vesting of restricted stock on a case by case basis at any time.
 
    FEDERAL INCOME TAX ASPECTS UNDER THE AMERUS STOCK PLAN.  The following is a
brief summary of the federal income tax consequences of awards made under the
AmerUs Stock Plan. This summary does not describe state, local or foreign tax
consequences. The information contained in this section is based on present law
and regulations, which are subject to be changed prospectively or retroactively.
 
    The optionee will recognize no taxable income upon the grant or exercise of
an Incentive Stock Option (as defined under the AmerUs Stock Plan), and AmerUs
will not be entitled to any deduction. Upon a disposition of the shares after
the later of two years from the date of grant and one year from the date of
exercise, the participant will recognize long-term capital gain or loss equal to
the difference, if any, between the amount realized and the exercise price. The
excess, if any, of the fair market value of the shares of AmerUs Class A Common
Stock on the date of exercise of the Incentive Stock Option over the exercise
price may be subject to alternative minimum tax. In such circumstances, no
deduction will be allowed to AmerUs for federal income tax purposes.
 
    If AmerUs Class A Common Stock acquired upon the exercise of an Incentive
Stock Option is disposed of prior to the expiration of the holding periods
described above, (i) the optionee will recognize ordinary compensation income in
the taxable year of disposition in an amount equal to the excess, if any, of the
lesser of the fair market value of the shares on the date of exercise and the
amount realized on the disposition of the shares, over the exercise price paid
for such shares; and (ii) AmerUs will be entitled to a corresponding deduction.
 
    With respect to Non-Qualified Options (as defined under the AmerUs Stock
Plan) (i) upon grant of the option, the optionee will recognize no income; and
(ii) upon exercise of the option, the optionee will recognize ordinary
compensation income in an amount equal to the excess, if any, of the fair market
value of the shares on the date of exercise over the exercise price, and AmerUs
will be entitled to a corresponding deduction. On the disposition of the shares,
the optionee will recognize gain or loss equal to the amount realized and the
sum of the exercise price and the ordinary compensation income realized. Such
gain or loss will be treated as either short-term or long-term capital gain or
loss, depending upon the length of time that the optionee has held the shares.
 
    An optionee recognizes no taxable income upon the grant of a SAR, and AmerUs
is not entitled to a deduction. An optionee will recognize ordinary income, and
AmerUs will be entitled to a deduction, at the time of exercise equal to the
cash or fair market value of common stock payable upon such exercise.
 
    The grant of Restricted Stock (as defined under the AmerUs Stock Plan) under
the AmerUs Stock Plan will not result in income for the grantee or in a
deduction for AmerUs, assuming the shares transferred are subject to a
"substantial risk of forfeiture" as intended by AmerUs. If there are no such
restrictions, the grantee would recognize ordinary income upon receipt of
shares. Dividends paid to the grantee while the stock remains subject to
restriction will be treated as compensation for federal income tax purposes. At
the time the restrictions lapse, the grantee will recognize ordinary income, and
AmerUs will be entitled to a deduction measured by the fair market value of the
shares at the time of lapse.
 
                                      156
<PAGE>
However, an optionee may elect to recognize income measured by the fair market
value of the shares at the time of grant and AmerUs will be entitled to a
corresponding deduction.
 
    Awards paid to certain executive officers may be subject to the limitations
under Section 162(m) of the Code that prohibit the deduction of certain
compensation paid in excess of $1,000,000 in any taxable year. The application
of such section to awards made under plans adopted and approved prior to the
time at which a company's stock becomes publicly traded is not clear. AmerUs
believes that compensation payable pursuant to options granted under the AmerUs
Stock Plan should not be limited as to deductibility by reason of Section 162(m)
and that compensation payable in respect of other awards may fail to be
deductible for federal income tax purposes unless such awards qualify for
certain exemptive relief that may be available for grants made prior to the
first meeting of shareholders of AmerUs at which directors are elected in 1999.
 
    On July 28, 1997, the Committee made grants of Non-Qualified Options under
the AmerUs Stock Plan to purchase AmerUs Class A Common Stock to the Named
Executive Officers as follows: Mr. Brooks (165,000 shares), Mr. Godlasky (60,000
shares), Mr. Sproule (60,000 shares) and Mr. Kalainov (165,000 shares). Mr. Doan
retired prior to July 28, 1997 and therefore did not receive options. On the
same date as the grants to the Named Executive Officers, Non-Qualified Options
for the purchase of 214,000 shares were made to 31 other employees of AmerUs.
All of the options granted have a per share exercise price equal to $27.875 and
expire on July 28, 2007.
 
      NON-EMPLOYEE DIRECTOR STOCK PLAN.  On September 15, 1996, AmerUs' Board
adopted the AmerUs Life Non-Employee Director Stock Plan (the "DIRECTOR PLAN").
The Director Plan was approved by AmerUs' sole shareholder and became effective
on December 4, 1996. The purpose of the Director Plan is to provide stock-based
compensation to eligible Directors of AmerUs in order to encourage a high level
of Director performance and to provide Directors with a proprietary interest in
AmerUs' success.
 
    The Director Plan provides for grants of restricted shares of AmerUs Class A
Common Stock ("RESTRICTED SHARES") and for the grant of options to purchase
shares of AmerUs Class A Common Stock. To date, no Restricted Shares or options
have been granted.
 
    The Director Plan is administered by the Committee. The total number of
shares of AmerUs Class A Common Stock reserved and available for distribution
under the Director Plan is 150,000. Such shares may consist, in whole or in
part, of authorized and unissued shares or treasury shares.
 
    Each Non-Employee Director of AmerUs is eligible to participate in the
Director Plan. A "Non-Employee Director" for this purpose means Directors who
are not officers for purposes of Section 16 of the Exchange Act or otherwise
employed, or a consultant to, AmerUs or any of its affiliates, and who is an
outside director under Section 1.162-27(e)(3) of the regulations promulgated
under the Code.
 
    STOCK OPTIONS.  Beginning January 1, 1998, options for 2,500 shares of
AmerUs Class A Common Stock will be granted to each Non-Employee Director
automatically on the first day of each calendar year in which the AmerUs Class A
Common Stock is publicly traded on Nasdaq. Options granted under the Director
Plan shall be evidenced by a written agreement in such form as the Committee
shall from time to time approve. The option price per share of AmerUs Class A
Common Stock purchasable under an option shall be 100% of the fair market value
of the AmerUs Class A Common Stock on the date of the grant of the option. Each
option shall be exercisable for a term of ten (10) years from the date such
option is granted. Options will not become exercisable until the expiration of
twelve (12) months from the date of the grant of the option.
 
    RESTRICTED STOCK AWARDS.  Each Non-Employee Director may elect, pursuant to
a written irrevocable election, to receive Restricted Stock in lieu of part or
all of such Non-Employee Director's director fees. The number of shares of
Restricted Stock granted to a Non-Employee Director pursuant to such election
shall be equal to the dollar amount of director fees which the Non-Employee
Director has
 
                                      157
<PAGE>
elected not to receive, divided by seventy-five percent (75%) of the fair market
value of the AmerUs Class A Common Stock as of the date of payment.
 
    Generally, a Non-Employee Director will not be permitted to sell, transfer,
pledge or assign shares of Restricted Stock awarded under the Director Plan for
a period of one (1) year following the effective date of the Restricted Stock
Agreement pursuant to which such shares of Restricted Stock are awarded.
 
    FEDERAL INCOME TAX ASPECTS UNDER THE DIRECTOR PLAN.  Federal income tax
consequences of options and Restricted Stock granted under the Director Plan are
the same as those described with respect to Non-Qualified Options and Restricted
Stock under the AmerUs Stock Plan.
 
  COMPENSATION PURSUANT TO PLANS OF AMERUS
 
    MANAGEMENT INCENTIVE PLAN.  AmerUs sponsors a Management Incentive Plan
("MIP") for officers and key management employees of AmerUs and its
subsidiaries. On an annual basis, AmerUs establishes various and distinct goals
for its executives and key managers. Goals generally relate to objectives such
as increased revenue, expense levels and earnings. Attainment of individual and
AmerUs goals can generate payment of cash bonuses ranging from 15% to 70% of an
executive's base salary. Payment of these annual incentives is approved by the
AmerUs Board and made in a separate lump-sum on or before the end of February of
the ensuing year.
 
    LONG-TERM INCENTIVE COMPENSATION PLAN.  AmerUs established a long-term
incentive compensation Performance Share Plan effective January 1, 1995 (the
"LTIP"). Under the LTIP, the Committee of the AmerUs Board has the authority to
grant Performance Shares to eligible employees on such dates as the Committee
shall determine. Performance Shares which were granted to Named Executive
Officers during 1996 are shown in the following table:

    SAVINGS AND PROFIT SHARING PLANS.  Each of the Named Executive Officers
participates in the All AmerUs Savings & Retirement Plan, formerly called the
All AmerUs Savings & Retirement Plan for Employees of American Mutual Life (the
"SAVINGS & RETIREMENT PLAN"), a profit sharing plan containing a qualified cash
or deferred arrangement, the All AmerUs Supplemental Executive Retirement Plan
(the "SUPPLEMENTAL PLAN") and the All AmerUs Excess Benefit Plan (the "EXCESS
PLAN"). Each of the Named Executive Officers also has a frozen benefit under
either the American Mutual Life Insurance Company Employees' Pension Plan (the
"AML EMPLOYEES' FROZEN PENSION PLAN") or the American Mutual Life Insurance
(formerly Central Life Assurance) Company Pension Plan (the "AML (FORMERLY
CENTRAL LIFE) FROZEN PENSION PLAN")(the AML Employees' Frozen Pension Plan and
the AML (formerly Central Life) Frozen Pension Plan are hereinafter sometimes
collectively referred to as the "FROZEN PENSION PLANS"). Certain of the Named
Executive Officers additionally have a frozen benefit under the American Mutual
Life Insurance Company Supplemental Executive Retirement Plan (the "AML FROZEN
SERP").
 
    Prior to December 31, 1995, AmerUs maintained three separate defined
contribution plans for eligible employees (collectively the "AMERUS FORMER
SAVINGS PLANS"). Contributions under the AmerUs Former Savings Plans ceased as
of December 31, 1995 and, effective January 1, 1996, the AmerUs
 
                                      158
<PAGE>
Former Savings Plans were merged into the Savings & Retirement Plan. AmerUs
amended the Savings & Retirement Plan, effective February 3, 1997, to allow
other affiliates to adopt the plan. AmerUs, and such entities which adopt the
Savings & Retirement Plan are hereinafter referred to as "Employers".
 
    The Savings & Retirement Plan is intended to be qualified under Section
401(a) of the Code and is administered by the AmerUs Benefit and Pension
Committee (the "BENEFITS COMMITTEE"), whose members are appointed by the AmerUs
Board. The Benefits Committee is responsible for interpreting the provisions of
the Savings & Retirement Plan, making certain amendments thereto and adopting
rules and regulations reasonably necessary or advisable to implement and
administer the AmerUs Stock Plan.
 
    The Savings & Retirement Plan allows for elective employee pretax
contributions, a core and matching contributions made by the Employers,
discretionary profit-sharing contributions and an individually-determined
interim benefit supplement, if applicable. Employee pretax contributions are
governed by Code Section 401(k). Participants may elect to make pretax
contributions to the Savings & Retirement Plan that are at least 1% and not more
than 15% of the participant's compensation. The Benefits Committee may reduce,
suspend or refund the contribution of a "highly compensated participant" (as
defined in the Savings & Retirement Plan) in order to ensure compliance with the
nondiscrimination tests set forth in the Savings & Retirement Plan.
 
    The Employers contribute 4% of each eligible participating employee's
compensation as of the end of a plan year in accordance with the provisions of
the Savings & Retirement Plan ("CORE CONTRIBUTIONS"). In addition, the Employers
make matching contributions of 125% of each employee's pretax contributions not
in excess of 4% of an employee's compensation ("MATCHING CONTRIBUTIONS").
 
    FROZEN PENSION PLANS.  Prior to January 1, 1996, American Mutual Life
maintained the Frozen Pension Plans, which were qualified under Section 401(a)
of the Code. Participants in the Frozen Pensions Plans ceased accruing benefits
under such plans as of December 31, 1995 and the Frozen Pension Plans were
merged into the surviving American Mutual Life Insurance Company Pension Plan
(the "SURVIVING AML PENSION PLAN"). Retirement benefits under the predecessor
AML Employees' Frozen Pension Plan were based primarily on an employee's years
of service, and compensation during the highest five consecutive plan years of
employment out of the last ten years of service, as of December 31, 1995;
retirement benefits under the predecessor AML (formerly Central Life) Frozen
Pension Plan were based primarily on an employee's years of service and career
compensation as of December 31, 1995. All employees' frozen accrued benefits as
of December 31, 1995 are fully vested.
 
    Prior to January 1, 1996, American Mutual Life also maintained the AML
Frozen SERP and the Central Life Frozen SERP, which were similar in operation to
the Supplemental Plan currently in effect. Participants in these plans ceased
accruing benefits under these plans as of December 31, 1995.

    The following table sets forth the frozen accrued monthly benefits payable

(1) Messrs. Brooks, Doan, Godlasky and Sproule have received an actuarially
    determined lump sum distribution of their accrued benefits under such plans.
 
(2) Included in this amount is $15,411 in monthly benefits due under the terms
    of an Employment Agreement, dated February 1, 1995, between American Mutual
    Life and Sam C. Kalainov. See "--Employment Agreement."
 
  SUPPLEMENTAL PLAN
 
    AmerUs adopted, effective January 1, 1996, the Supplemental Executive
Retirement Plan (the "SUPPLEMENTAL PLAN"). Certain employees whose benefits
under the Savings & Retirement Plan are limited by the provisions of Section
401(a)(17) of the Code and for whom compensation is deferred (including the
Named Executive Officers), are eligible to participate in such plan. The
Supplemental Plan is not intended to meet the qualification requirements of
Section 401 of the Code, and no cash or funds shall be set aside or otherwise
segregated for the payment of benefits under such plan until such time as
benefits are actually paid.
 
  EXCESS PLAN
 
    AmerUs also adopted, effective January 1, 1996, the Excess Plan. Employees
whose benefits under the Savings & Retirement Plan are limited by Section 415 of
the Code are eligible to participate in such plan. The Excess Plan is not
intended to meet the qualification requirements of Section 401 of the Code, and
no cash or funds shall be set aside or otherwise segregated for the payment of
benefits under such plan until such time as benefits are actually paid.
 
  EMPLOYMENT AGREEMENT
 
    AmerUs Life entered into an employment agreement (the "EMPLOYMENT
AGREEMENT") with Mr. Kalainov, dated February 1, 1995, under which he served as
the Chairman of the AmerUs Life Board and Chairman of AmerUs Life's Charitable
Foundation. The term of the Employment Agreement was to continue until May 15,
2000, but could expire earlier if Mr. Brooks ceased to perform the duties of
Chief Executive Officer of AmerUs Life. If Mr. Kalainov's service as Chairman
were terminated prior to May 15, 2000, AmerUs Life was required to execute a
consulting contract with him pursuant to which, among other things, AmerUs Life
was obligated to pay the difference between the benefits Mr. Kalainov received
under AmerUs Life's pension plans and the sum of his base salary plus incentive
compensation for the preceding 12 months. The Employment Agreement provided that
Mr. Kalainov would serve as Chairman of the Foundation until May 15, 2000.
 
                                      160

                                               endowment contract) or annuity contract
                                               issued by AmerUs.
 
PREMIUM......................................  Payments and considerations received on
                                               insurance policies and annuity contracts
                                               issued or reinsured by an insurance company.

                                               deferred annuity contracts are not accounted
                                               for as revenues.
 
REINSURANCE..................................  The practice whereby one party, called the
                                               reinsurer or assuming company, in
                                               consideration of a premium paid to such
                                               party, agrees to indemnify another party,
                                               called the ceding company or primary insurer,
                                               for risks underwritten by the ceding company.
                                               Reinsurance provides a primary insurer with
                                               three major benefits: it reduces net
                                               liability on individual risks; it helps to
                                               protect against catastrophic losses; and it
                                               helps to maintain acceptable surplus and
                                               reserve ratios. Reinsurance provides a
                                               primary insurer with additional underwriting
                                               capacity in that the primary insurer can
                                               accept larger risks and can expand the volume
                                               of business it writes without increasing its
                                               capital base. The ceding company remains
                                               liable on its obligations under the policies
                                               reinsured if the reinsurer fails to pay
                                               claims on a reinsured policy.

                                               upon the death of the second to die of the

SEPARATE ACCOUNTS............................  Investment accounts maintained by an insurer
                                               to which funds have been allocated for
                                               certain policies under provisions of relevant
                                               state law. The investments in each separate
                                               account are maintained separately from those
                                               in other separate accounts and the general
                                               account. The investment results of the
                                               separate account assets are passed through
                                               directly to the separate account
                                               policyowners, so that an insurer derives
                                               management and other fees from, but bears no
                                               investment risk on, these assets, except the
                                               risk on a small number of products that
                                               returns on separate assets will not meet the
                                               relatively low minimum rate guaranteed on
                                               these products.

                                               policy. Premiums, net of specified expenses,

                                               considerable flexibility as to the amount and
                                               timing of premium payments and for the level

                                               purchase accumulation units. The value of a
                                               unit fluctuates in accordance with the
                                               investment experience of a separate account;
                                               variable annuity contracts typically include
                                               a general account guaranteed interest

                                               of benefits to the annuitant, the annuitant
                                               can generally elect from a number of payment
                                               options which provide either fixed or
                                               variable benefit payments.

                                               of years), and (iii) single premium life
                                               insurance (a lump sum amount paid at the
                                               inception of the policy). The insurance
                                               policy pays a benefit (contractual amount
                                               adjusted for items such as policy loans and
                                               dividends, if any) at the death of the
                                               insured. Whole life insurance also builds up
                                               cash values.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
AmerUs Life Holdings, Inc.:
 
    We have audited the accompanying consolidated balance sheets of AmerUs Life
Holdings, Inc. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the years in the three-year period ended December 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of AmerUs Life
Holdings, Inc. and subsidiaries as of December 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996, in conformity with generally accepted
accounting principles.
 
    As discussed in note 1 to the consolidated financial statements, the Company
implemented the provisions of the Statement of Financial Accounting Standards
(SFAS) No. 120, "Accounting and Reporting by Mutual Life Insurance Enterprises
and by Insurance Enterprises for Certain Long-Duration Participating Contracts."
Also, as discussed in note 1, the Company restated its consolidated financial
statements to reflect the spin-off of a wholly owned subsidiary in 1996, which
resulted in a change in the subsidiaries comprising the consolidated financial
statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  NATURE OF OPERATIONS
 
    AmerUs Life Holdings, Inc.'s (the Company) operations consist primarily of
marketing, underwriting, and distributing life insurance, annuities, and related
products to individuals throughout the United States. The Company's products are
sold through a career general agency system and a personal producing general
agency system. The life insurance and annuity operations are the Company's only
business segment.
 
  ORGANIZATION AND PRINCIPLES OF CONSOLIDATION
 
    The Company was formed on August 1, 1996 in conjunction with a plan of
reorganization (the Reorganization) of the former American Mutual Life Insurance
Company (American Mutual Life). Pursuant to the Reorganization which became
effective on June 30, 1996 (the Effective Date), American Mutual Life was
converted to a mutual insurance holding company structure whereby American
Mutual Holding Company (AMHC), a mutual insurance holding company, was formed.
Additionally, American Mutual Life was converted to a stock life insurance
company and renamed AmerUs Life Insurance Company (AmerUs Life). All of the
initial shares of capital stock of AmerUs Life were issued to AMHC.
 
    On August 1, 1996, AMHC contributed all of its shares of capital stock of
AmerUs Life to AmerUs Group Co. (AmerUs Group). On the same date, the Company
was formed, and all of its shares of capital stock were issued to AmerUs Group.
 
    Prior to the distribution (Distribution) by AmerUs Life of its Non-Life
Insurance Subsidiaries (as defined below), AmerUs Life made a capital
contribution of cash and other property (Capital Contribution) to or for the
benefit of AmerUs Properties, Inc., AmerUs Bank and Iowa Realty Co., Inc., and
each of their respective subsidiaries (Non-Life Insurance Subsidiaries). The net
assets contributed in the Capital Contribution had an aggregate carrying value
of approximately $79 million as of the date of contribution. Following the
Capital Contribution, a series of transactions was undertaken by the Company and
its affiliates. AmerUs Life effected the Distribution, pursuant to which it
distributed the Non-Life Insurance Subsidiaries to AmerUs Group. Immediately
after the Distribution, AmerUs Group contributed all of its shares of common
stock in AmerUs Life to the Company. Under this structure, the Company is an
intermediate holding company, with AmerUs Group as its direct parent company and
AmerUs Life as its wholly-owned subsidiary. Under Iowa law, AMHC is required to
retain direct or indirect ownership and control of shares representing a
majority of the vote of the outstanding capital stock of the Company.
Immediately following the Distribution, the Company entered into a bank credit
facility pursuant to which it borrowed $100 million in term debt and $75 million
under a revolving line of credit (Bank Credit Facility). The Company used the
proceeds from such borrowings to make a $125 million capital contribution to
AmerUs Life and to purchase a $50 million surplus note from AmerUs Life.
 
    The effect of the Distribution was to decrease (increase) net income by
$6,292,000, $10,539,000, ($101,000) in the years ended December 31, 1996, 1995,
and 1994, respectively, such amounts representing the net income (loss) of
Lartnec Investment Co., a former subsidiary of AmerUs Life, and its subsidiaries
(collectively, Lartnec).
 
    As a result of the Reorganization, AMHC indirectly owned, through AmerUs
Group, 14,500,000 shares of Class A Common Stock and 5,000,000 shares of Class B
Common Stock of the Company. The Class B Common Stock must be held, directly or
indirectly, by AMHC. The Class B Common Stock is generally convertible on a
share-for-share basis for Class A Common Stock. Each share of Class A and Class
B Common Stock entitles its holder to one vote per share; however, the voting
rights are adjusted if the number of Class A shares exceed the number of Class B
shares such that the holders of Class B shares will always have a majority of
the votes. AMHC must directly or indirectly control a majority of the voting
shares of AmerUs Life. In addition, as long as the members of AMHC own directly
or indirectly at

least 50.1 percent of the voting power of the outstanding voting stock, AMHC is
entitled to equity purchase rights which provide for the Company to notify AMHC
in writing of a proposed sale of voting stock or any options, warrants, or
rights to acquire voting stock. AMHC has the right to purchase the same
proportionate number of shares being offered for sale as AMHC owns of the total
shares at the time of the registration.
 
    In February 1997, AmerUs Group sold 2,793,489 shares of Class A common stock
to the public and the Company issued 3,655,989 shares of Class A common stock in
its initial public offering for gross proceeds of $56.7 million. As a result,
AmerUs Group's ownership of the Company was reduced to 72.15%.
 
    The accompanying consolidated financial statements include only the accounts
and operations, after intercompany eliminations, of AmerUs Life Holdings, Inc.
and its wholly owned subsidiaries, principally, AmerUs Life Insurance Company
and American Vanguard Life Insurance Company (American Vanguard Life). The
consolidated financial statements do not include the results of operations or
financial position of the Non-Life Insurance Subsidiaries.
 
    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles (GAAP) requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
CLOSED BLOCK
 
    The Reorganization contained an arrangement, known as a closed block (the
Closed Block), to provide for dividends on policies that were inforce on the
Effective Date and were within the classes of individual policies for which the
Company had a dividend scale in effect at the time of the Reorganization. The
Closed Block was designed to give reasonable assurance to owners of affected
policies that assets will be available to support such policies, including
maintaining dividend scales in effect at the time of the Reorganization, if the
experience underlying such scales continues. The assets, including revenue
therefrom, allocated to the Closed Block will accrue solely to the benefit of
the owners of policies included in the block until the block is no longer in
effect. The Company will not be required to support the payment of dividends
except those contractually guaranteed on Closed Block policies from its general
funds.
 
    The financial information of the Closed Block, while prepared on a GAAP
basis, reflects its contractual provisions and not its actual results of
operations and financial position. Many expenses related to the Closed Block
operations are charged to operations outside of the Closed Block; accordingly,
the contribution from the Closed Block does not represent the actual
profitability of the Closed Block operations. Operating costs and expenses
outside of the Closed Block are, therefore, disproportionate to the business
outside of the Closed Block.

  BASIS OF PRESENTATION
 
    The accompanying consolidated financial statements of the Company and its
wholly owned subsidiaries have been prepared in conformity with GAAP which, as
to the insurance company subsidiaries, differ from statutory accounting
practices prescribed or permitted by regulatory authorities.
 
    The insurance company subsidiaries adopted SFAS 120, "Accounting and
Reporting by Mutual Life Insurance Enterprises and by Insurance Enterprises for
Certain Long-Duration Participating Contracts", in 1995. SFAS 120 permits stock
life insurance companies to apply the provisions of the American Institute of
Certified Public Accountant's Statement of Position 95-1, "Accounting for
Certain Insurance Activities of Mutual Life Insurance Enterprises," to
participating life insurance contracts that meet the conditions in SFAS 120. The
accompanying consolidated financial statements have been restated for the
effects of implementing SFAS 120.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  INTERIM FINANCIAL INFORMATION
 
    The consolidated financial statements as of June 30, 1997, and for the
six-month periods ended June 30, 1997 and 1996, and related disclosures in these
notes have not been audited. The interim consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and notes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring accruals unless
noted otherwise herein) considered necessary for a fair presentation have been
included. Operating results for the six-month period ended June 30, 1997, are
not necessarily indicative of the results that may be expected for the year
ending December 31, 1997. (See Note 16).
 
  INVESTMENTS
 
    Investments in fixed maturity and equity securities that are to be held for
indefinite periods of time are reported as securities available for sale.
Securities available for sale are reported in the accompanying consolidated
financial statements at fair value. Any valuation changes resulting from changes
in the fair value of these securities are reflected as a component of
stockholders' equity. These unrealized gains or losses in stockholders' equity
are reported net of taxes and adjustments to deferred policy acquisition costs.
 
    Premiums and discounts on fixed maturity securities are amortized or
accreted over the life of the related security as an adjustment to yield using
the effective interest method. Realized gains and losses are included in
earnings and are determined using the specific identification method. The
carrying value of investments is reduced to its estimated realizable value if a
decline in fair value is considered other than temporary with such reduction
charged to earnings.
 
    Mortgage loans on real estate and other long-term investments are stated at
cost less amortized discounts and allowances for possible losses. Policy loans
are stated at their aggregate unpaid balances. Real estate acquired by
foreclosure is stated at the lower of cost or fair value less estimated costs to
sell.
 
    Investments in real estate and mortgage loans on real estate are considered
impaired when the Company determines that collection of all amounts due under
the contractual terms is doubtful or carrying values exceed the fair value of
underlying collateral. The Company adjusts real estate and mortgage loans on
real estate to their estimated net realizable value at the point at which it
determines an impairment is other than temporary. Interest income on impaired
mortgage loans is recognized when cash is received. In addition, the Company has
established a valuation allowance for mortgage loans on real estate and other
invested assets. Valuation allowances for other than temporary impairments in
value are netted against the asset categories to which they apply, and additions
to valuation allowances are included in total investment results.
 
    Investment in unconsolidated subsidiary is carried on an equity basis
consisting of the cost of the original investment and the Company's allocable
share of net earnings, unrealized gains and losses on available-for-sales
securities, and return of capital.
 
  INTEREST RATE SWAPS, CAPS AND SWAPTIONS
 
    The Company uses interest rate swaps, caps, and swaptions as part of its
overall interest rate risk management strategy for certain life insurance and
annuity products. The book values of the interest rate swaps, caps, and
swaptions are amortized over the remaining lives of the hedged investments as
adjustments to investment income. Certain agreements hedge assets which are
carried at fair value; accordingly, such underlying hedged investments are also
carried at fair value. Any unamortized gains or losses are recognized when the
underlying investments are sold.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Interest rate swap contracts are used to convert the interest rate
characteristics (fixed or variable) of certain investments to match those of the
related insurance liabilities that the investments are supporting. The net
interest effect of such swap transactions is reported as an adjustment of
interest income as incurred.
 
    Interest rate caps are used to limit the effects of changing interest rates
on yields of variable rate or short-term assets or liabilities. The initial cost
of any such agreement is amortized to investment income over the life of the
agreement. Periodic payments that are receivable as a result of the agreements
are accrued as an adjustment of investment income.
 
    Swaption agreements are used in conjunction with interest rate caps to
protect against rising rates. Swaption agreements involve the right to enter
into a swap transaction at a pre-specified price. The initial cost of a swaption
agreement is amortized to investment income over the life of the agreement.
 
  POLICY ACQUISITION COSTS
 
    Certain commissions, policy issue and underwriting costs, and other variable
costs incurred to acquire or renew traditional life insurance, universal life
insurance, and annuity products have been deferred. The amortization method of
deferred policy acquisition costs for traditional life insurance products is
different, dependent upon whether the contract is participating or
non-participating. Participating contracts are those which are expected to pay
dividends to policyowners in proportion to their relative contribution to the
Company's surplus. Deferred policy acquisition costs for participating
traditional life insurance are being amortized over the life of the policies
generally in proportion to the present value of estimated gross margins.
Non-participating traditional life insurance deferred policy acquisition costs
are being amortized over the premium-paying period of the related policies in
proportion to the ratio of annual premium revenues to total anticipated premium
revenues using assumptions consistent with those used in computing policy
benefit reserves. For universal life insurance and annuity products, deferred
policy acquisition costs are being amortized generally in proportion to the
present value of estimated gross margins from surrender charges and investment,
mortality, and expense margins. The amortization for participating traditional
life, universal life, and annuity products is adjusted retrospectively when
current or estimated future gross profits or margins on the underlying policies
vary from previous estimates. Deferred policy acquisition costs are adjusted for
the impact on estimated gross profits of net unrealized gains and losses on
securities.
 
  RECOGNITION OF REVENUES
 
    Premiums for traditional life insurance products (including those products
with fixed and guaranteed premiums and benefits and which consist principally of
whole life insurance policies and certain annuities with life contingencies) are
recognized as revenues when due. For limited payment life insurance policies,
premiums are recorded as income when due with any excess profit deferred and
recognized over the expected lives of the contracts. Amounts received as
payments for universal life insurance policies and for annuity products
(including deferred annuities and annuities without life contingencies) are not
recorded as premium revenue. Revenues for such contracts consist of policy
charges for the cost of insurance, policy administration charges, and surrender
charges assessed against policyowner account balances during the period. All
insurance-related revenue is reported net of reinsurance ceded.
 
  FUTURE POLICY BENEFITS
 
    The liability for future policy benefits for traditional life insurance is
computed using the net level method, utilizing the guaranteed interest and
mortality rates used in calculating cash surrender values as described in the
contracts. Reserve interest assumptions range from 2.00 percent to 7.25 percent.
The weighted average assumed interest rate for all traditional life policy
reserves was 4.23 percent in 1996,

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
4.20 percent in 1995 and 4.10 percent in 1994. Policy benefit claims are charged
to expense in the period that the claims are incurred. All insurance-related
benefits, losses, and expenses are reported net of reinsurance ceded.
 
    Future policy benefit reserves for universal life insurance and annuity
products are computed under a retrospective deposit method and represent policy
account balances before applicable surrender charges. Policy benefits and claims
that are charged to expense include benefit claims incurred in the period in
excess of related policy account balances. The weighted average interest
crediting rate for universal life products was 6.27 percent in 1996, 6.46
percent in 1995 and 6.44 percent in 1994. The weighted average interest
crediting rate for annuity products was 5.36 percent in 1996, 6.16 percent in
1995 and 6.41 percent in 1994.
 
  PARTICIPATING POLICIES
 
    Participating policies entitle the policyowners to receive dividends based
on actual interest, mortality, morbidity, and expense experience for the related
policies. These dividends are distributed to the policyowners through an annual
dividend using current dividend scales which are approved by the board of
directors. Nearly 100 percent of traditional life policies are currently paying
dividends and traditional life policies represent 67 percent of the Company's
individual life policies inforce.
 
  PROPERTY AND EQUIPMENT
 
    Property and equipment is recorded at cost and is depreciated principally
under the straight-line method.
 
  GUARANTY FUND ASSESSMENTS
 
    The Company is subject to insurance guaranty laws in the states in which it
writes business. These laws provide for assessments against insurance companies
for the benefit of policyowners and claimants in the event of insolvency of
other life insurance companies. As of December 31, 1996, the Company has accrued
for the gross amount of guaranty fund assessments for known insolvencies net of
estimated recoveries of premium tax offsets.
 
  BENEFIT PLAN COSTS
 
    The Company recognizes pension costs for its defined benefit plans in
accordance with SFAS 87, "Employers' Accounting for Pensions." Pension costs are
funded according to regulations provided under the Internal Revenue Code.
 
  POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
    Under SFAS 106, "Employers' Accounting for Postretirement Benefits Other
Than Pensions," the cost of postretirement benefits must be recognized on an
accrual basis as employees perform services to earn the benefits. The Company
adopted SFAS 106 as of January 1, 1993. Prior to 1993, the cost of retiree
health care and life insurance benefits was recognized as an expense when paid.
 
  INCOME TAXES
 
    The Company and its subsidiaries, with the exception of American Vanguard
Life, file a consolidated federal income tax return with the Non-Life Insurance
Subsidiaries. The separate return method is used to compute the Company's
provision for federal income taxes. Deferred income tax assets and liabilities
are determined based on differences among the financial reporting and tax bases
of assets and liabilities and are measured using the enacted tax rates and laws.
 
  EMERGING ACCOUNTING MATTER
 
    In June 1996, the FASB issued Statement No. 125, "Accounting for Transfers
and Servicing of Financial Assets and Extinguishments of Liabilities." SFAS No.
125 provides consistent accounting

standards for securitizations and other transfers of financial assets,
determines when financial assets (liabilities) should be considered sold
(settled) and removed from the balance sheet, and determines when related
revenues and expenses should be recognized. FASB Statement No. 125 is effective
for transfers and servicing of financial assets and extinguishments of
liabilities occurring after December 31, 1996. This statement will be applicable
to the Company, however, management believes that it will have no material
effect on the Company's consolidated financial statements.
 
  BUSINESS RISKS
 
    The Company operates in a business environment which is subject to various
risks and uncertainties. Such risks and uncertainties include interest rate
risk, legal and regulatory changes, and default risk.
 
    Interest rate risk is the potential for interest rates to change, which can
cause fluctuations in the value of investments. To the extent that fluctuations
in interest rates cause the duration of assets and liabilities to differ, the
Company may have to sell assets prior to their maturity and realize losses.
Interest rate exposure for the investment portfolio is managed through
asset/liability management techniques which attempt to match the duration of the
assets with the estimated duration of the liabilities. The Company also utilizes
derivative investment contracts to manage interest rate risk.
 
    The potential also exists for changes in the legal or regulatory environment
in which the Company operates, which can create additional costs and expenses
not anticipated by the Company in pricing its products. In other words,
regulatory initiatives or new legal theories may create costs for the Company
beyond those recorded in the financial statements. The Company mitigates this
risk by operating in a geographically diverse area, which reduces its exposure
to any single jurisdiction, closely monitoring the regulatory environment to
anticipate changes, and by using underwriting practices which identify and
minimize the potential adverse impact of this risk.
 
    Default risk is the risk that issuers of securities owned by the Company may
default or that other parties, including reinsurers, may not be able to pay
amounts due the Company. The Company minimizes this risk by adhering to a
conservative investment strategy, holding a well diversified portfolio of assets
to minimize concentrations, maintaining sound reinsurance and credit and
collection policies, and providing allowances or reserves for any amounts deemed
uncollectible.
 
  EARNINGS PER COMMON SHARE
 
    Earnings per share have been computed on a pro forma basis by giving
retroactive effect to the issuance of 18.16 million shares of Class A common
stock and 5 million shares of Class B common stock as if all such shares had
been issued at the beginning of the respective periods and by giving retroactive
effect to the Capital Contribution.

    million from the proceeds of a common or preferred offering and regular
    semi-annual payments of $5 million commencing in June 1997. The revolving
    credit loan provides for a maximum borrowing of $75 million with the balance

    however, the Company may elect to fix the rate for periods from 30 days to
    six months. The Bank Credit Facility contains various financial and

    The differential earnings amount is an equity add-on tax which mutual life
insurance companies are required to pay. The amount is determined annually and
is calculated by comparing the earnings rate of mutual life insurance companies
and certain stock life insurance companies. In certain years, such as 1993 and
1995, the calculations have resulted in negative adjustments with no additional
tax amount to be paid.
 
    The Company's federal income tax expense (benefit) is summarized as follows:

    The Company is required to establish a "valuation allowance" for any portion
of the deferred tax asset that management believes will not be realized. In the
opinion of management, it is more likely than not that it will realize the
benefit of the deferred tax assets, and, therefore, no such valuation allowance
has been established.
 
    During 1996, the Company transferred $0.8 million in deferred tax
liabilities related to assets contributed in the Capital Contribution.
 
    Federal Income tax returns for the Company for years through 1989 are closed
to further assessment of taxes. The Internal Revenue Service is examining
federal income tax returns of the Company for 1990 through 1992. Management
believes adequate provisions have been made for any additional taxes which may
become due with respect to open years.
 
    Income taxes paid by the Company totaled $45.4 million, $51.9 million and
$14.6 million in the years ended December 31, 1996, 1995 and 1994, respectively.
 
(7) DEFINED BENEFIT PENSION PLANS
 
    The Company has defined benefit pension plans which cover substantially all
of the Company's employees, as well as employees of certain affiliated
companies. The plans provide for benefits based upon years of service and the
employee's compensation. Information for the Company's portion of the plans'
funded status is not available. The Company has frozen the defined benefit
pension plans effective December 31, 1995, and has recognized its portion of a
curtailment gain amounting to $6.2 million, or $3.1 million after federal excise
taxes, as other revenues in 1995. Effective January 1, 1996, the defined benefit
pension plans have been replaced by a defined contribution savings and
retirement plan which also replaces the Company's defined contribution pension
plans. The following information

special termination benefits for the plan was approximately $1.6 million.
 
  DEFINED CONTRIBUTION PENSION PLANS
 
    The Company has three defined contribution 401(k) plans which cover
substantially all employees. The Company's total contribution under the plans

single defined contribution savings and retirement plan to which total
contributions from the Company amounted to $2.4 million in 1996.

    The weighted-average annual assumed rate of increase in the per capita cost
of covered benefits (i.e., health care cost trend rate) for the medical and
dental plan is approximately 8.50 percent, 9.00 percent, and 9.50 percent for
1996, 1995, and 1994, respectively, and is assumed to decrease gradually to 5.00
percent over seven years and remain at that level thereafter. The health care
cost trend rate assumption has a significant effect on the amounts reported. For
example, increasing the assumed health care cost trend rates by one percentage
point in each year would increase the accumulated postretirement benefit
obligation for the medical plan as of December 31, 1995 by 7.70 percent and the
aggregate of the service and interest cost components of net periodic
postretirement benefit expense for 1995 and 1994, by $.06 million and $.02
million, respectively, on a combined basis. As of January 1, 1996 the plan was
changed to provide a fixed monthly benefit for medical benefits; accordingly,

(9) REINSURANCE
 
    At December 31, 1996, the Company's maximum retention limit for acceptance
of risk on life insurance was $1 million. The retention limit for certain
policies issued prior to July 1, 1985, was $125,000 and for certain policies
issued after June 30, 1985, and before December 1, 1994, was $250,000. There are
reinsurance agreements with various companies whereby insurance in excess of
these retention limits are reinsured. Insurance in-force ceded to nonaffiliated
companies under risk sharing arrangements at December 31, 1996, 1995 and 1994,
totaled approximately $4,170 million, $3,814 million and $3,265 million,
respectively.

(9) REINSURANCE (CONTINUED)
    Total life premiums ceded amounted to $14.8 million, $14.2 million and $13.7
million for the years ended December 31, 1996, 1995, and 1994, respectively.
Total life premiums assumed amounted to $1.5 million, $4.9 million and $7.9
million, respectively.
 
    To the extent that reinsuring companies are unable to meet obligations under
these agreements, the Company remains liable. To limit the possibility of such
losses, the Company evaluates the financial condition of its reinsurers and
monitors concentration of credit risk.
 
(10) COMMITMENTS AND CONTINGENCIES
 
    The Non-Life Insurance Subsidiaries had various credit lines and
arrangements totaling $85 million at December 31, 1996. Approximately $62
million was outstanding under these agreements at December 31, 1996, which were
collateralized by Company investments of approximately $88 million. Subsequent
to December 31, 1996, the Company's collateral was released.
 
    The Company has agreed to make loans to newly formed partnerships, of which
$26,600,000 was outstanding as of December 31, 1996.
 
    The Company guarantees the payment of 60 percent of a pool of mortgage loans
and the related interest, previously sold to an unrelated party. The outstanding
balance of such mortgage loans subject to this repayment guarantee at December
31, 1996, was approximately $10 million.
 
    The Company is party to financial instruments in the normal course of
business to meet the financing needs of its customers having risk exposure not
reflected in the balance sheet. These financial instruments include commitments
to extend credit and standby letters of credit. Commitments to extend credit are
agreements to lend to customers. Commitments generally have fixed expiration
dates and may require payment of a fee. Since many commitments expire without
being drawn upon, the total amount of commitments does not necessarily represent
future cash requirements. At December 31, 1996, outstanding commitments to
extend credit totaled approximately $15.5 million.
 
    The Company and its joint venture partner are contingently liable in the
event the joint venture, Ameritas Variable Life Insurance Company (AVLIC),
cannot meet its policyholder obligations. At December 31, 1996, AVLIC had
statutory assets of $1,108 million, liabilities of $1,049 million, and surplus
of $59 million.
 
    AmerUs Life is a defendant in a class action lawsuit which was brought on
August 31, 1995 in the District Court for Travis County, Texas. The complaint,
which seeks unspecified damages, was filed by former policyowners on behalf of
themselves and all similarly situated persons who purchased certain individual
life insurance policies which were underwritten and sold by AmerUs Life within
Texas from and after 1980. The complaint alleges that sales presentations and
policy illustrations misrepresented that premiums would "vanish" after a stated
number of years, without adequate disclosure of the effect of changes in the
policy dividends. AmerUs Life has denied the allegations contained in such
complaint and denies any wrongdoing in connection with such allegations. The
parties have engaged in discovery, but a hearing on certification of the class
has not yet been held.
 
    The parties are engaged in a court-initiated mediation process in the Texas
litigation and, in light of the uncertainties, hazards and expenses of
litigation, have discussed a number of different settlement approaches,
including a nationwide class settlement of certain market conduct issues for a
substantial block of the Company's traditional whole life policies. Progress in
negotiating such a class settlement appears to have been made, but certain
issues remain unresolved and no definitive agreement has been reached. Even if
such an agreement were reached, the court would have to approve its terms.

settlement satisfactory to the Company not be reached or not be approved, the
Company would continue to vigorously defend against the claims asserted,
including the existence of a legitimate class.
 
    Due to the potential that a settlement may be reached in this case, the
Company has incurred a significant charge to income for 1996. Based upon its
current estimates of the range of loss at between five and eight million
dollars, the Company has established a reserve of five million dollars. The
eventual costs of any settlement cannot be precisely determined at this time,
and may be more or less than the amount of the range.
 
    A class action lawsuit was filed in June 1996 in the United States District
Court for the Northern District of California. The complaint alleges that AmerUs
Life breached the terms of certain life and annuity policies, and breached
certain other duties owed to policyowners, when it allegedly passed an increase
in its corporate income taxes (known as the deferred acquisition cost, or DAC,
tax) through to owners of those policies. The Plaintiff, an insured under a
universal life policy issued by Central Life, seeks unspecified actual and
punitive damages and injunctive relief on behalf of himself and all policyowners
of AmerUs Life with universal life, term and "blended" life insurance policies
and annuities. The plaintiff has recently filed a second complaint in the same
court, based upon the same facts but adding RICO allegations to those made in
the original lawsuit. AmerUs Life denies the allegations contained in both
complaints, including the existence of a legitimate class. The litigation is in
the early discovery stage and is being vigorously defended by AmerUs Life and
the potential range of loss cannot be currently estimated. A hearing on
certification of the class has not yet been scheduled.
 
    Despite the Company's vigorous defense of these class action lawsuits and
its denial of any wrongdoing, there can be no assurance that the outcome of such
lawsuits will not have a material adverse effect on the life insurance industry
generally or on the Company. In the ordinary course of business, the Company and
its subsidiaries are also engaged in certain other litigation, none of which
management believes is material.
 
(11) STOCKHOLDERS' EQUITY
 
    Generally, the stockholders' equity of the Company's insurance subsidiaries
available for distribution to the Company are limited to the amounts that the
insurance subsidiaries' net assets, as determined in accordance with statutory
accounting practices, exceed minimum statutory capital requirements; however,
payments of such amounts as dividends may be subject to approval by regulatory
authorities. In 1997, the Company's insurance subsidiaries could distribute
approximately $34 million in the form of dividends to the Company without prior
approval of such regulatory authorities. However, as a result of the
distribution and capital contribution, the Company will not be able to pay
additional dividends in the 12-month period following the Distribution of the
Non-Life Insurance Subsidiaries without the prior approval of the Iowa
Commissioner.
 
    The Company made additional contributions to the Non-Life Insurance
Subsidiaries amounting to $4.2 million, $41.2 million, and $5.0 million, in the
years ended December 31, 1996, 1995, and 1994, respectively, which have been
considered dividends to AMHC as a result of the Distribution.
 
(12) STATUTORY ACCOUNTING PRACTICES
 
    The Company's insurance subsidiaries' statutory net income was $62.4
million, $59.9 million, and $20.3 million in the years ended December 31, 1996,
1995, and 1994, respectively.
 
    The Company's insurance subsidiaries' statutory surplus and capital was
$283.0 million, and $276.3 million at December 31, 1996 and 1995, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
 
(12) STATUTORY ACCOUNTING PRACTICES (CONTINUED)
    The Company's insurance subsidiaries are domiciled in Iowa and prepare their
statutory-basis financial statements in accordance with accounting practices
prescribed or permitted by the Iowa Department of Commerce (Iowa Department).
Prescribed statutory accounting practices include state laws, regulations, and
general administrative rules, as well as a variety of publications of the
National Association of Insurance Commissioners (NAIC). Permitted statutory
accounting practices encompass all accounting practices that are not prescribed;
such practices may differ from state to state, may differ from company to
company within a state, and may change in the future. The NAIC currently is in
the process of codifying statutory accounting practices, the result of which is
expected to constitute the only source of prescribed statutory accounting
practices. Accordingly, that project, which is expected to be completed in 1997,
will likely change, to some extent, prescribed statutory accounting practices
and may result in changes to the accounting practices that insurance enterprises
use to prepare their statutory financial statements.
 
    The Company does not utilize any permitted practices in the preparation of
its statutory-basis financial statements which would have a material impact on
statutory surplus.
 
    The Iowa Department imposes minimum risk-based capital requirements on
insurance enterprises that were developed by the NAIC. The formulas for
determining the amount of risk-based capital (RBC) specify various weighting
factors that are applied to financial balances or various levels of activity
based on the perceived degree of risk. Regulatory compliance is determined by a
ratio (the Ratio) of the enterprise's regulatory total adjusted capital, as
defined by the NAIC, to its authorized control level, RBC, as defined by the
NAIC. Enterprises below specific trigger points or ratios are classified within
certain levels, each of which requires specified corrective action.
 
    AmerUs Life has a Ratio that is at least 700 percent of the authorized
control level RBC requirements; accordingly, AmerUs Life exceeds the RBC
requirements.
 
(13) FINANCIAL INSTRUMENTS
 
    The Company utilizes a variety of off-balance-sheet financial instruments as
part of its efforts to hedge and manage fluctuations in the market value of its
portfolio of available-for-sale securities, attributable to changes in general
interest rate levels, and to manage duration mismatch of assets and liabilities.
Those instruments include interest rate exchange agreements (swaps, caps and
swaptions) and involve elements of credit and market risks in excess of the
amounts recognized in the accompanying financial statements at a given point in
time. The contract or notional amounts of those instruments reflect the extent
of involvement in the various types of financial instruments.
 
    The Company's exposure to credit risk is the risk of loss from a
counterparty failing to perform according to the terms of the contract. That
exposure includes settlement risk (i.e., the risk that the counterparty defaults
after the Company has delivered funds or securities under terms of the contract)
that would result in an accounting loss and replacement cost risk (i.e., the
cost to replace the contract at current market rates should the counterparty
default prior to settlement date). To limit exposure associated with
counterparty nonperformance on interest rate exchange agreements, the Company
enters into master netting agreements with its counterparties.
 
    The credit risk on all financial instruments, whether on or off the balance
sheet, is controlled through an on-going credit review, approval, and monitoring
process. The Company determines, on an individual counterparty basis, the need
for collateral or other security to support financial instruments with credit
risk and establishes individual and aggregate counterparty exposure limits.

  INTEREST RATE EXCHANGE AGREEMENTS
 
    The Company enters into interest rate exchange agreements to reduce and
manage interest rate risk associated with individual assets and liabilities and
its overall aggregate portfolio. The interest rate swap agreements, which expire
between 1999 and 2001, generally involve the exchange of fixed and floating rate
interest payments, without an exchange of the underlying principal. The interest
rate cap agreements, which expire between 1997 and 2001, involve the payment of
a maximum fixed interest rate when an indexed rate exceeds that fixed rate.
Swaption agreements, which expire between 1999 and 2002, involve the right to
enter into a swap transaction at a pre-specified price. These agreements are
used in conjunction with interest rate caps to protect against rising rates. The
amounts to be received or paid pursuant to those agreements are accrued and
recognized in the accompanying consolidated statements of income through an
adjustment to investment income over the life of the agreements. The net effect
on income from amortization and interest paid or received was an increase of
$0.9 million and $1.5 million for the years ended December 31, 1996 and 1995,
respectively. There were no material effects in 1994. Gains or losses realized
on closed or terminated agreements accounted for as hedges are deferred and
amortized to investment income on a constant yield basis over the shorter of the
life of the agreements or the expected remaining life of the underlying assets
or liabilities.

    The Company is exposed to credit loss in the event of nonperformance by
counterparties on interest rate cap and interest rate swap agreements. The
Company does not anticipate nonperformance by any of these counterparties. The
credit risk associated with such agreements is minimized by purchasing such
agreements from financial institutions with long-standing, superior performance
records. The amount of such exposure is essentially their replacement cost,
which is approximated by the unrealized gains in such contracts.
 
    The Company has no current exposure to the counterparty when a contract
contains an unrealized loss.

    rate information will change accordingly.
 
(14) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    SFAS 107, "Disclosures about Fair Values of Financial Instruments," requires
disclosures of fair value information about financial instruments, whether
recognized or not recognized in a company's balance sheet, for which it is
practicable to estimate that value. In cases where quoted market prices are not
available, fair values are based on estimates using discounted cash flow or
other valuation techniques. Those techniques are significantly affected by the
assumptions used, including the discount rates and estimates of the amount and
timing of future cash flows. SFAS 107 excludes certain insurance liabilities and
other non-financial instruments from its disclosure requirements. The fair value
amounts presented herein do not include an amount for the value associated with
customer or agent relationships, the expected interest margin (interest earnings
over interest credited) to be earned in the future on investment-type products,
or other intangible items. Accordingly, the aggregate fair value amounts
presented herein do not necessarily represent the underlying value of the
Company; likewise, care should be exercised in deriving conclusions about the
Company's business or financial condition based on the fair value information
presented herein.
 
    The Company closely monitors the level of its insurance liabilities, the
level of interest rates credited to its interest sensitive products, and the
assumed interest margin provided for within the pricing structure of its other
products. Those amounts are taken into consideration in the Company's overall
management of interest rate risk that attempts to minimize exposure to changing
interest rates through the matching of investment maturities with amounts
expected to be due under insurance contracts. As such, the Company believes that
it has reduced the volatility inherent in its fair value adjusted policyowners'
equity, although such volatility will not be reduced completely. The Company has
used discount rates in the determination of fair values for its liabilities that
are consistent with market yields for related assets. The use of the asset
market yield is consistent with management's opinion that the risks inherent in
the Company's asset and liability portfolios are similar, and the fact that fair
values for both assets and

(14) FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
liabilities generally will react in much the same manner during periods of
interest rate changes. However, that assumption might not result in fair values
that are consistent with values obtained through an actuarial appraisal of the
Company's business or values that might arise in a negotiated transaction.
 
    The following presentation reflects fair values for those instruments
specifically covered by SFAS 107, along with fair value amounts for those
traditional insurance liabilities for which disclosure is permitted but not
required; the fair values for all other assets and liabilities have been
reported at their carrying amounts.
 
  VALUATION METHODS AND ASSUMPTIONS
 
    The following methods and assumptions were used to estimate the fair value
of each class of financial instruments:
 
    Cash, short-term investments, policy loans, accrued investment income: the
carrying amounts for these instruments approximate their fair values.
 
    Fixed maturities and equity securities: fair values for bonds are based on
quoted market prices or dealer quotes. If a quoted market price is not
available, fair value is estimated using values obtained from independent
pricing services or, in the case of private placements, are estimated by
discounting expected future cash flows using a current market rate applicable to
the yield, credit quality, and maturity of the investments. The fair values for
preferred and common stocks are based on quoted market prices.
 
    Mortgage loans on real estate: for all performing fixed interest rate loans,
the estimated net cash flows to maturity were discounted to derive an estimated
market value. The discount rate used was based on the individual loan's
remaining weighted average life and a basis point spread based on the market
conditions for the type of loan and credit quality. These spreads were over the
December 31, 1996, United States treasury yield curve. Performing variable rate
commercial loans and residential loans were valued at the current outstanding
balance. Loans which have been restructured, are in foreclosure, are
significantly delinquent, or are to affiliates were valued primarily at the
lower of the estimated net cash flows to maturity discounted at a market rate of
interest or the current outstanding principal balance.
 
    Hedging instruments: fair values for derivative securities are based on
pricing models or formulas using current assumptions and are classified as other
assets or other liabilities.
 
    Policy reserves: fair values of the Company's liabilities under contracts
not involving significant mortality or morbidity risks (principally, annuities)
are stated at the cost the Company would incur to extinguish the liability;
I.E., the cash surrender value.
 
    Debt: fair values for debt are estimated using discounted cash flow analysis
based on the Company's current incremental borrowing rate for similar types of
borrowing arrangements.
 
    The carrying amounts of other financial assets, dividends payable to
policyowners, and policy reserves including significant mortality or morbidity
risks approximate their fair values.

    On February 3, 1997, the Company issued $86,000,000 of 8.85% Capital
Securities, Series A, through a wholly-owned subsidiary trust. The sole asset of
the trust is the junior subordinated debentures of the Company in the principal
amount of $88.66 million with interest at 8.85% maturing February 1, 2027. The
Company has fully and unconditionally guaranteed the obligation of the trust
under the Capital Securities and is obligated to mandatorily redeem the
securities on February 1, 2027. The Company may prepay the securities at anytime
after February 1, 2007.
 
(C) FEDERAL INCOME TAXES
 
    The effective income tax rate for the period ending June 30, 1997 was lower
than the prevailing corporate rate primarily as a result of earned low income
housing and historic rehabilitation credits.
 
(D) COMMITMENTS AND CONTINGENCIES
 
    AmerUs Life is a defendant in a class action lawsuit, Cozad v. American
Mutual Life Insurance Company, which was brought on August 31, 1995 in the
District Court for Travis County, Texas. The complaint, which seeks unspecified
damages, was filed by former policyowners on behalf of themselves and all
similarly situated persons who purchased individual life insurance policies
which were underwritten and sold by AmerUs Life within Texas and which were
allegedly based upon uniform sales presentations and policy illustrations from
and after 1980. AmerUs Life has denied the allegations contained in such
complaint.
 
    Following a court-initiated mediation process, the Company and the
plaintiffs have entered into a nationwide class settlement of certain market
conduct issues for a substantial block of its policies. On September 16, 1997,
the court entered an order approving the certification of the class and the
fairness of the settlement, subject only to an appeal, if any. A final hearing
has been scheduled following notice to class members. There can be no assurance
the agreement will be approved by the court and become effective. Should a
settlement not be approved, this litigation would continue and the Company would
continue to vigorously defend against claims asserted, including the existence
of a legitimate class. Due to the potential that a settlement may be reached in
this case, the Company incurred a significant charge to income in 1996. Based
upon its current estimates of the range of loss at between five and eight
million dollars, the Company has established a reserve of five million dollars.
The eventual costs of any

settlement cannot be precisely determined at this time, and may be more or less
than the amount of the range.
 
    A class action lawsuit was filed in June 1996 in the United States District
Court for the Northern District of California. The complaint alleges that AmerUs
Life breached the terms of certain life and annuity policies, and breached
certain other duties owed to policyowners, when it allegedly passed an increase
in its corporate income taxes (known as the deferred acquisition cost, or DAC,
tax) through to owners of those policies. The Plaintiff, an insured under a
universal life policy issued by Central Life, seeks unspecified actual and
punitive damages and injunctive relief on behalf of himself and all policyowners
of AmerUs Life with universal life, term and "blended" life insurance policies
and annuities. The plaintiff has recently filed a second complaint in the same
court, based upon the same facts but adding RICO allegations to those made in
the original lawsuit. AmerUs Life denies the allegations contained in both
complaints, including the existence of a legitimate class. The litigation is in
the early discovery stage and is being vigorously defended by AmerUs Life and
the potential range of loss cannot be currently estimated. A hearing on
certification of the class has not yet been scheduled.
 
    AmerUs and its joint venture partner are contingently liable in the event
the joint venture, Ameritas Variable Life Insurance Company (AVLIC), cannot meet
its policyholder obligations. At December 31, 1996, AVLIC had statutory assets
of $1,108 million, liabilities of $1,049 million, and surplus of $59 million.

(F) SUBSEQUENT EVENTS
 
DELTA LIFE
 
    The Company completed the acquisition of Delta Life Corporation following
receipt of an order on October 23, 1997 from the Tennessee Department of
Commerce and Insurance approving the change of control for $162.9 million in
cash. Delta Life Corporation provides deferred annuity and equity index annuity
products through an insurance subsidiary and had assets of approximately $2.0
billion, at the date of the closing.
 
    On October 23, 1997, the Company entered into a new bank credit facility and
repaid the term loan under the prior bank credit facility. The new loan
agreement provides for a $250 million revolving credit facility on substantially
the same terms as the former agreement. The Company immediately borrowed $235
million to finance the acquisition of Delta Life Corporation, retire the former
term loan and retire certain indebtedness of Delta.
 
AMVESTORS
 
    On September 19, 1997, the Company entered into an agreement and plan of
merger which provides for the issuance of Class A Common Stock in exchange for
the outstanding common stock of AmVestors Financial Corporation (AmVestors)
after which, AmVestors will survive as a subsidiary of the Company. AmVestors
had approximately $206 million of revenues from the sale of life insurance and
annuity products and net investment income during the year ended December 31,
1996 and had approximately $3.3 billion in assets at that date. The transaction
is subject to approval by the shareholders of the Company and AmVestors and also
regulatory approval, but is expected to close in 1997.
 
(G) RELATED PARTY TRANSACTIONS
 
    AmerUs Life entered into a master agreement of purchase and sale with AmerUs
Bank, dated as of March 5, 1997, whereby AmerUs Life agreed to purchase whole
loans from AmerUs Bank from time to time. AmerUs Life also entered into a loan
servicing agreement with AmerUs Bank, dated as of March 5, 1997, whereby AmerUs
Bank acts as servicer of the loans and receives a servicing fee ranging from 50
to 58 basis points of the outstanding principal balances of the loans. AmerUs
Life has made three purchases under this agreement during 1997. On March 7,
1997, $25.3 million in outstanding principal at a $1.4 million premium; on
September 10, 1997, $39.1 million in outstanding principal at a $2.7 million
premium; and on September 28, 1997, $34.0 million in outstanding principal at a
$2.4 million premium. Subsequent to September 30, 1997, these loans were sold by
AmerUs Life at a small gain.
 
    AmerUs Life entered into a purchase agreement with AmerUs Mortgage dated
March 1, 1997, whereby AmerUs Life has committed to purchase up to $200 million
principal amount of first mortgage loans originated by AmerUs Mortgage. The
commitment expires on December 31, 1997, and is terminable by either party upon
sixty days' notice. To date, AmerUs Life has purchased 13 mortgage loans
pursuant to such commitment for a total purchase price of $1.8 million.

                          AGREEMENT AND PLAN OF MERGER
 
    THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER (this "AGREEMENT") is
dated as of September 19, 1997 and amended as of October 8, 1997, and is by and
among AmVestors Financial Corporation, a Kansas corporation (the "COMPANY"),
AmerUs Life Holdings, Inc., an Iowa corporation ("PARENT"), and AFC Corp., a
Kansas corporation and a subsidiary of Parent ("SUB"). A Glossary of Terms is
attached as Annex A and incorporated herein by reference.
 
                                    RECITALS
 
    WHEREAS, the respective Boards of Directors of Parent, Sub and the Company
have approved the merger of Sub into the Company, upon the terms and subject to
the conditions set forth in this Agreement, whereby each issued and outstanding
share of common stock, no par value, of the Company (the "COMPANY COMMON
STOCK"), not owned directly or indirectly by Parent or held in treasury by the
Company, will be converted into the right to receive the Merger Consideration
(as defined below), on the terms set forth herein;
 
    WHEREAS, Parent, Sub and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger; and
 
    WHEREAS, for federal income tax purposes, it is intended that the Merger of
the Company and Sub shall qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "CODE"),
and that this Agreement shall be, and is hereby, adopted as a plan of
reorganization for the purposes of Section 368 of the Code.
 
                                   AGREEMENT
 
    NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties and covenants set forth herein and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    SECTION 1.01  THE MERGER.
 
    (a) Subject to the terms and conditions of this Agreement, at the Effective
Time (as defined in Section 1.01(b)), Sub shall be merged with and into the
Company (the "MERGER") in accordance with the Kansas Statutes Annotated ("KSA"),
Chapter 17 (the "KGCC"), whereupon the separate existence of the Sub shall
cease, and the Company shall be the surviving corporation (the "SURVIVING
CORPORATION").
 
    (b) The consummation of the Merger (the "CLOSING") shall take place (i) at
the offices of Bryan Cave LLP, One Metropolitan Square, 211 North Broadway,
Suite 3600, St. Louis, Missouri, at 10:00 A.M., on such date (the "CLOSING
DATE") which is three business days after the date on which the last of the
conditions set forth in Article 8 hereof shall have been satisfied or waived in
accordance with this Agreement, or (ii) such other place, time and date as the
parties hereto shall agree. Prior to the Closing, Sub and the Company shall
execute and deliver to the Secretary of State of the State of Kansas (the
"KANSAS SECRETARY OF STATE") a Certificate of Merger in proper form for filing
under the KGCC on the day of the Closing, and the Merger shall become effective
upon the filing of the Certificate of Merger with the Kansas Secretary of State
or at such later time as may be specified in the Certificate of Merger, such
time being herein called the "EFFECTIVE TIME".
 
    (c) The Merger shall have the effects set forth in the KGCC. Without
limiting the generality of the foregoing, at the Effective Time (i) the
Surviving Corporation shall possess all assets and property of every
description, and every interest therein, wherever located, and the rights,
privileges, immunities,
 
                                      I-1
<PAGE>
power, franchises, and authority, of a public as well as of a private nature, of
each of the Company and the Sub and all obligations belonging to or due each of
them shall be vested in the Surviving Corporation without further act or deed;
(ii) title to any real estate or any interest therein vested in either of the
Company or the Sub shall not revert or in any way be impaired by reason of the
Merger; (iii) all rights of creditors and all liens on any property of the
Company and the Sub shall be preserved unimpaired; and (iv) the Surviving
Corporation shall be liable for all the obligations of the Company and the Sub,
and any claim existing, or action or proceeding pending, by or against either of
them, may be prosecuted to judgment with the right of appeal, as if the Merger
had not taken place.
 
    SECTION 1.02  STOCK OPTIONS.
 
    (a) As soon as practicable following the date of this Agreement, but in any
event not less than fifteen trading days prior to the Closing, the Board of
Directors of the Company (or, if appropriate, any committee administering the
Company's 1989 Non-Qualified Stock Option Plan (the "NQSO PLAN") or 1996
Incentive Stock Option Plan (the "ISO PLAN," and together with the NQSO Plan,
the "COMPANY OPTION PLANS") shall adopt such resolutions or take such other
actions as may be required to adjust the terms of all outstanding Company
Options (as defined in Section 3.03) issued pursuant to the Company Option Plans
and related agreements, to provide that at the Effective Time, each Company
Option outstanding (whether or not vested and exercisable) immediately prior to
the Effective Time shall at the Effective Time cease to represent a right to
acquire shares of Company Common Stock and shall be converted automatically into
an option (a "CONTINUING OPTION") to acquire Parent Common Stock in an amount
and at an exercise price determined as provided in the immediately following
sentence (and on substantially the same terms and conditions as were applicable
under such Company Option Plan and the agreements evidencing grants thereunder),
subject to Section 1.02(b). At the Effective Time, if the holder of a Company
Option which is then outstanding and unexercised has not timely elected (with
respect to Company Options granted under the NQSO Plan) or has not timely
requested (with respect to Company Options granted under the ISO Plan; or if so
requested, if such request has been denied by the Company) to receive cash for
such Company Option as described in subsection (b) of this Section 1.02, then
such Company Option shall, in accordance with the provisions of the NQSO Plan or
the ISO Plan, whichever is applicable, become a Continuing Option to acquire (x)
the number of shares of Parent Common Stock equal to the product of (i) the
number of shares of Company Common Stock subject to such Company Option
immediately prior to the Effective Time multiplied by (ii) the Merger
Consideration (a partial share shall be rounded down to the next lower whole
share), with (y) an exercise price equal to the quotient of (i) the original
exercise price per share (the "ORIGINAL EXERCISE PRICE") of Company Common Stock
subject to such Company Option in effect immediately prior to the Effective Time
divided by (ii) the Merger Consideration and rounding the exercise price thus
determined to the nearest whole cent (a half cent shall be rounded to the next
higher whole cent). In the case of Company Options intended to be incentive
stock options (as defined in Section 422 of the Code), the exercise price,
number of shares of Parent Common Stock subject to such Continuing Option and
terms and conditions or exercise of such Continuing Option shall be determined
in order to comply with the requirements of Section 424(a) of the Code.
 
    (b) As soon as practicable following the date of this Agreement, but in any
event not less than fifteen trading days prior to the Closing, the Company shall
deliver to the holders of Company Options (whether or not vested and
exercisable) a Cash Option Notice Form (as defined below) offering to (i)
holders of Company Options issued pursuant to the NQSO Plan the right to elect,
and (ii) holders of Company Options issued pursuant to the ISO Plan the right to
request, to receive in consideration for the cancellation of all (but not less
than all) of such holder's Company Options, an amount in cash equal to the
product of (x) the excess of (i) the Option Cash Price (as defined below), over
(ii) the Original Exercise Price of such Company Option, multiplied by (y) the
number of shares subject to such Company Option. The "OPTION CASH PRICE" is the
product of (A) the last reported sales price per share of Parent Common Stock as
quoted by Nasdaq (as defined below) on the Closing Date multiplied by (B) the
Merger Consideration. Alternatively, with the consent of Parent prior to the
Closing, holders of
 
                                      I-2
<PAGE>
Company Options may request to receive in consideration for the cancellation of
such holder's Company Options, a number of shares of Parent Common Stock
(rounded down to the nearest whole share) equal to the amount of cash which
otherwise would be payable upon termination of such Company Options pursuant to
the first sentence of this Section 1.02(b), divided by the last sales price of
Parent Common Stock as reported on Nasdaq as of the Effective Time.
 
    (c) As soon as practicable after the Effective Time, Parent shall deliver to
the holders of Continuing Options appropriate notices setting forth such
holders' rights pursuant to the respective Company Option Plans.
 
    (d) To make the election for cash consideration described in Section 1.02(b)
above, any eligible Company Option holder must deposit with the Exchange Agent
at least ten trading days prior to the Closing a properly completed notice
("CASH OPTION NOTICE FORM"), in form and substance reasonably satisfactory to
Parent (including an appropriate release), and the Option Agreements (as defined
below) relating to any such Company Options for which such election is made.
Such election shall be irrevocable unless the Agreement is terminated before the
Effective Time. Following the Effective Time, the Company shall deliver to each
such holder the cash amount so elected, calculated in accordance with Section
1.02(b) above. No interest shall be paid on such amount. If this Agreement is
terminated before the Effective Time, the Option Agreement(s) shall be returned
to each such holder.
 
    SECTION 1.03  STOCK APPRECIATION RIGHTS.  Following the Effective Time, the
holders of outstanding Company SARs (as defined in Section 3.03(e) hereof),
shall be entitled to receive in consideration for the cancellation of such
Company SAR an amount in cash equal to the product of (x) the excess of (i) the
Option Cash Price over (ii) the strike price of such Company SAR, multiplied by
(y) the number of shares of Company Common Stock referenced by the Company SARs;
provided, that Parent shall have received from each such holder a written
acknowledgement that such payment is in full satisfaction of the Company's and
Parent's obligations in respect of the Company SARs.
 
    SECTION 1.04  ARTICLES OF INCORPORATION AND BY-LAWS.
 
    (a) The Articles of Incorporation of the Company, as in effect immediately
prior to the Effective Time, shall be the Articles of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided therein or
by applicable law.
 
    (b) The By-Laws of Sub as in effect immediately prior to the Effective Time
shall be the By-Laws of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable law.
 
    SECTION 1.05  DIRECTORS.  The individuals who are the directors of Sub
immediately prior to the Effective Time shall be the directors of the Surviving
Corporation until thereafter they cease to be directors in accordance with the
KGCC and the Articles of Incorporation and By-Laws of the Surviving Corporation.
 
    SECTION 1.06  OFFICERS.  The individuals who are the officers of the Company
immediately prior to the Effective Time shall be the officers of the Surviving
Corporation until thereafter they cease to be officers in accordance with the
KGCC and the Articles of Incorporation and By-Laws of the Surviving Corporation.
 
                                   ARTICLE II
                   EFFECT OF THE MERGER ON THE CAPITAL STOCK
                        OF THE CONSTITUENT CORPORATIONS;
                            EXCHANGE OF CERTIFICATES
 
    SECTION 2.01  CAPITAL STOCK OF SUB.  As of the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
Company Common Stock or any shares of capital stock of Sub, each share of common
stock, without par value, of Sub issued and outstanding immediately prior to the
Effective Time shall be converted into and become one fully paid and
nonassessable share of common stock, without par value, of the Surviving
Corporation.
 
                                      I-3
<PAGE>
    SECTION 2.02  CANCELLATION OF TREASURY STOCK AND PARENT OWNED STOCK.  As of
the Effective Time, by virtue of the Merger and without any action on the part
of the holder of any shares of Company Common Stock or any shares of capital
stock of Sub, each share of Company Common Stock issued and held immediately
prior to the Effective Time in the Company's treasury and each share of Company
Common Stock that is owned by Parent, Sub or any other subsidiary of Parent
shall automatically be canceled and retired and shall cease to exist, and no
consideration shall be delivered in exchange therefor. At the Effective Time,
shares of Company Common Stock held by subsidiaries of the Company shall be
converted into the right to receive the Merger Consideration in accordance with
Section 2.03.
 
    SECTION 2.03  CONVERSION OF COMPANY COMMON STOCK.
 
    (a) As of the Effective Time, by virtue of the Merger and without any action
on the part of the holder of any shares of Company Common Stock or any shares of
capital stock of Sub, except as otherwise provided in this Section 2.03 and
subject to Section 2.04(f), each share of Company Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares to be
canceled in accordance with Section 2.02) shall be converted into the right to
receive (x) if the Average Parent Share Price (as defined below) is greater than
or equal to $27.00 but less than or equal to $29.75, the number of shares of
Parent Common Stock (as defined in Section 4.10 hereof) determined by dividing
$20.00 by the Average Parent Share Price and rounding the result to the nearest
one ten-thousandth of a share; (y) if the Average Parent Share Price is less
than $27.00, 0.7407 shares of Parent Common Stock (subject to the next
succeeding paragraph); and (z) if the Average Parent Share Price is greater than
$29.75, 0.6724 shares of Parent Common Stock (as applicable, the "MERGER
CONSIDERATION"); provided, however, that, in any event, if between the date of
this Agreement and the Effective Time the outstanding shares of Parent Common
Stock shall have been changed into a different number of shares or a different
class, by reason of any stock dividend, subdivision, reclassification,
recapitalization, split, combination or exchange of shares, the Merger
Consideration shall be correspondingly adjusted to the extent appropriate to
reflect such stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares. The "AVERAGE PARENT SHARE PRICE" means
the average of the last reported sales prices per share of Parent Common Stock
as quoted by The Nasdaq National Market ("NASDAQ") for the 20 consecutive
trading days ending on the trading day (the "PRICE MEASURING DATE") which is ten
trading days prior to the Closing Date.
 
    (b) In the event that the Average Parent Share Price on the Price Measuring
Date is less than $27.00, the Company shall have the option to deliver a written
notice to Parent on the trading day following the Price Measuring Date providing
for the termination of this Agreement pursuant to this Section 2.03(b) and
Article IX, subject to the next sentence (the "TERMINATION NOTICE"). If the
Company properly delivers a Termination Notice, this Agreement shall terminate
in accordance with Article IX hereof at the close of business on the fifth
trading day following the Price Measuring Date unless prior to such time Parent
shall have delivered to the Company a written notice whereby the Parent agrees
to adjust the consideration into which each share of Company Common Stock from
the Merger Consideration as determined above to the number of shares of Parent
Common Stock (the "ADJUSTED MERGER CONSIDERATION") determined by dividing $20.00
by the Average Parent Share Price as of the Price Measuring Date and rounding
the result to the nearest one ten-thousandth of a share.
 
    (c) As of the Effective Time, all such shares of Company Common Stock shall
no longer be outstanding and shall automatically be canceled and retired and
shall cease to exist, and each holder of a certificate representing any such
shares of Company Common Stock shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration.
 
    SECTION 2.04  EXCHANGE OF CERTIFICATES.
 
    (a) EXCHANGE AGENT. From and after the Effective Time, (i) Parent shall make
available to a bank or trust company designated by Parent and reasonably
satisfactory to the Company (the "EXCHANGE AGENT"), for the benefit of the
holders of shares of Company Common Stock, for exchange in accordance with this
Article II through the Exchange Agent, (i) certificates evidencing such number
of shares of Parent Common Stock issuable to holders of Company Common Stock in
the Merger pursuant to
 
                                      I-4
<PAGE>
Section 2.03 and (ii) upon request of the Exchange Agent cash in the amount
required to be exchanged for shares of Company Common Stock in the Merger
pursuant to Section 2.04(f) (such certificates for shares of Parent Common
Stock, together with any dividends or distributions with respect thereto and
cash, being hereinafter referred to as the "EXCHANGE FUND"). The Exchange Agent
shall, pursuant to irrevocable instructions, deliver the Parent Common Stock
contemplated to be issued pursuant to Section 2.03 out of the Exchange Fund.
Except as contemplated by Section 2.04(f) hereof, the Exchange Fund shall not be
used for any other purpose. The Exchange Agent shall invest any cash included in
the Exchange Fund, as directed by Parent, on a daily basis. Any interest and
other income resulting from such investments shall be paid to Parent.
 
    (b) EXCHANGE PROCEDURES. As promptly as practicable after the Effective
Time, Parent shall cause the Exchange Agent to mail to each holder of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "CERTIFICATES") (i)
a letter of transmittal (which shall be in customary form and shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates evidencing shares of Parent Common Stock.
 
    (c) EXCHANGE OF CERTIFICATES. Upon surrender to the Exchange Agent of a
Certificate for cancellation, together with such letter of transmittal, duly
executed and completed in accordance with the instructions thereto, and such
other documents as may be reasonably required pursuant to such instructions, the
holder of such Certificate shall be entitled to receive in exchange therefor (i)
a Certificate representing that number of whole shares of Parent Common Stock,
if any, which such holder has the right to receive pursuant to this Article II
and (ii) a check in the amount equal to the cash, if any, which such holder has
the right to receive pursuant to the provisions of this Article II (including
any cash in lieu of any fractional shares of Parent Common Stock to which such
holder is entitled pursuant to Section 2.04(f) and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.04(d)), and
the Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of shares of Company Common Stock which is not registered
in the transfer records of the Company, the applicable Merger Consideration,
cash in lieu of any fractional shares of Parent Common Stock to which such
holder is entitled pursuant to Section 2.04(f) and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.04(d) may
be issued to a transferee if the Certificate representing such shares of Company
Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.04, each Certificate shall be deemed at all times
after the Effective Time to represent only the right to receive upon such
surrender the applicable Merger Consideration with respect to the shares of
Company Common Stock formerly represented thereby, cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 2.04(f) and any dividends or other distributions to which
such holder is entitled pursuant to Section 2.04(d).
 
    (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF PARENT COMMON STOCK.
No dividends or other distributions declared or made after the Effective Time
with respect to Parent Common Stock with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock represented thereby, and no cash payment in lieu
of any fractional shares shall be paid to any such holder pursuant to Section
2.04(f), until the holder of such Certificate shall surrender such Certificate.
Subject to the effect of escheat, tax or other applicable laws, following
surrender of any such Certificate, there shall be paid to the holder of the
certificates representing whole shares of Parent Common Stock issued in exchange
therefor, without interest, (i) promptly, the amount of any cash payable with
respect to a fractional share of Parent Common Stock to which such holder is
entitled pursuant to Section 2.04(f) and the amount of dividends or other
distributions with a record date after the Effective Time and theretofore paid
with respect to such whole shares of Parent Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions,
 
                                      I-5
<PAGE>
with a record date after the Effective Time but prior to surrender and a payment
date occurring after surrender, payable with respect to such whole shares of
Parent Common Stock.
 
    (e) NO FURTHER RIGHTS IN COMPANY COMMON STOCK. All shares of Parent Common
Stock issued or cash paid upon conversion of the shares of Company Common Stock
in accordance with the terms hereof (including any cash paid pursuant to Section
2.04(d) or (f)) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Common Stock.
 
    (f)  NO FRACTIONAL SHARES. No certificates or scrip representing fractional
shares of Parent Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interests will not entitle the owner
thereof to vote or to any other rights of a shareholder of Parent. Each holder
of a fractional share interest shall be paid an amount in cash equal to the
product obtained by multiplying (i) such fractional share interest to which such
holder (after taking into account all fractional share interests then held by
such holder) would otherwise be entitled by (ii) the product of the (x) Merger
Consideration or (y) Adjusted Merger Consideration, as appropriate, and the
Average Parent Share Price. As promptly as practicable after the determination
of the amount of cash, if any, to be paid to holders of fractional share
interests, the Exchange Agent shall so notify Parent, and Parent shall deposit
such amount with the Exchange Agent and shall cause the Exchange Agent to
forward payments to such holders of fractional share interests subject to and in
accordance with the terms of Sections 2.04(b), (c) and (d).
 
    (g) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund
(including any shares of Parent Common Stock) which remains undistributed to the
holders of Company Common Stock for one year after the Effective Time shall be
delivered to Parent, upon demand, and any holders of Company Common Stock who
have not theretofore complied with this Article II shall thereafter look only to
Parent for the applicable Merger Consideration, any cash in lieu of fractional
shares of Parent Common Stock to which they are entitled pursuant to Section
2.04(f) and any dividends or other distributions with respect to the Parent
Common Stock to which they are entitled pursuant to Section 2.04(d). Any portion
of the Exchange Fund remaining unclaimed by holders of shares of Company Common
Stock as of a date which is immediately prior to such time as such amounts would
otherwise escheat to or become property of any government entity shall, to the
extent permitted by applicable law, become the property of Parent free and clear
of any claims or interest of any person previously entitled thereto.
 
    (h) NO LIABILITY. None of the Exchange Agent, Parent nor the Surviving
Corporation shall be liable to any holder of shares of Company Common Stock for
any such shares of Parent Common Stock (or dividends or distributions with
respect thereto), or cash delivered to a public official pursuant to any
abandoned property, escheat or similar law.
 
    (i)  WITHHOLDING RIGHTS. Each of the Surviving Corporation and Parent shall
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of Company Common Stock such
amounts as it is required to deduct and withhold with respect to the making of
such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by the Surviving Corporation or
Parent, as the case may be, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the shares of
Company Common Stock in respect of which such deduction and withholding was made
by the Surviving Corporation or Parent, as the case may be.
 
    (j)  LOST CERTIFICATES. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such person of a bond, in such reasonable
amount as the Surviving Corporation may direct, as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate the
applicable Merger Consideration, any cash in lieu of fractional shares of Parent
Common Stock to which the holders thereof are entitled pursuant to Section
2.04(f) and any dividends or other distributions to which the holders thereof
are entitled pursuant to this Agreement.
 
                                      I-6

Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title and interest in, to or under any of the rights,
properties or assets of either the Sub or the Company acquired or to be acquired

desirable to vest, perfect or confirm any and all right, title and interest in,
to and under such rights, properties or assets in the Surviving Corporation or
otherwise to carry out the purposes of this Agreement.
 
    SECTION 2.05  STOCK TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of Company Common Stock thereafter on the
records of the Company. From and after the Effective Time, the holders of
certificates representing shares of Company Common Stock outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to such
shares of Company Common Stock, except as otherwise provided herein or by law.
On or after the Effective Time, any Certificates presented to the Exchange Agent
or Parent for any reason shall be converted into shares of Parent Common Stock,
any cash in lieu of fractional shares of Parent Common Stock to which the

Section 2.04(d).

amended (the "SECURITIES ACT").

    (a) The Company has made available to Parent true and complete copies of the
following financial statements (the "COMPANY FINANCIAL STATEMENTS"):
 
        (i)  audited (A) annual GAAP Statements for the Company and (B) Annual
    Statements for the Company Insurance Subsidiaries, for each of the years
    ended December 31, 1994, 1995, and 1996, including all the notes thereto;
    and
 
        (ii) unaudited (A) quarterly GAAP Statements for the Company and (B)
    Quarterly Statements for the Company Insurance Subsidiaries, for each of the
    first three quarters of each of 1995 and 1996, and the first two quarters of
    1997, including all the notes thereto.
 
    (b) Each such Company Financial Statement (and the notes thereto), and each
GAAP Statement and Quarterly Statement made available by the Company pursuant to
Section 5.04, including without limitation each balance sheet and each of the
statements of operations, capital and surplus account, and cash flow contained
therein was prepared in accordance with SAP ("SAP STATEMENTS") or GAAP ("GAAP
STATEMENTS"), respectively, except as may be otherwise indicated in notes filed

the financial condition and results of operations and cash flows of the Company
and its consolidated subsidiaries or the Company Insurance Subsidiaries, as
 
                                      I-10
<PAGE>
the case may be, as of the respective dates thereof or for the respective
periods presented therein, subject, in the case of quarterly statements, to
normal year end adjustments. Each SAP Statement was timely filed and complied in
all material respects with all applicable Laws when filed with the applicable
insurance regulatory authority, and any deficiencies known to the Company with
respect to any such SAP Statement have been cured or corrected to the
satisfaction of such insurance regulatory authority.
 
    (c) Except as indicated on Section 3.08 of the Company Disclosure Schedule,
the Company has not received written notice from the Kansas Commissioner of
Insurance ("KCI") or the Florida Commissioner of Insurance ("FCI") asserting any
deficiency with respect to such SAP Statements.
 
    (d) Since December 31, 1996, the Company Insurance Subsidiaries have filed
all reports and other filings, together with any amendments required to be made
with respect thereto, that it has been required to file with state insurance
regulatory authorities (the "COMPANY INSURANCE SUBSIDIARIES FILINGS"), and all
of the Company Insurance Subsidiaries Filings prior to the date hereof complied,
and all such filings made hereafter prior to the Effective Time will comply, in
all material respects with applicable insurance laws, rules and regulations,

ceding of insurance, assumption of insurance or indemnification with respect to
insurance or similar material arrangements applicable to the Company Insurance
Subsidiaries or their properties or assets (collectively, "REINSURANCE
AGREEMENTS") is not fully collectible in due course. The Company Insurance
Subsidiaries are entitled to take full credit in their SAP Statements pursuant
to applicable insurance laws, rules and regulations for such reinsurance,
coinsurance or excess insurance ceded pursuant to any such Reinsurance

actuarial standards consistently applied, are fairly stated in accordance with
sound actuarial principles, are based on actuarial assumptions that are in
accordance with those called for by the provisions of the related insurance and
annuity Contracts and in the related reinsurance, coinsurance and other similar
Contracts of the Company Insurance Subsidiaries, and meet in all material
respects the requirements of the insurance Laws of its state of domicile.
Adequate provision for all such Reserve Liabilities have been made (under
generally accepted actuarial principles consistently applied) to cover the total
amount of all reasonably anticipated matured and unmatured benefits, dividends,
claims and other liabilities of the Company Insurance Subsidiaries under all
insurance and annuity Contracts under which the Company Insurance Subsidiaries
have any liability (including without limitation any liability arising under or
as a result of any reinsurance, coinsurance or other similar Contract) on the
respective dates of such SAP Statement based on then current information
regarding interest earnings, mortality and morbidity experience, persistency and
expenses. The Company Insurance Subsidiaries own assets that qualify as legal
reserve assets under applicable insurance Laws in an amount at least equal to
all such Reserve Liabilities; and
 
    (b) Adequate provision has been made for all estimated losses, settlements,
costs and expenses from pending suits, actions and proceedings included in the
December 31, 1996 Annual Statement and the latest Quarterly Statements, and the
reserves and accrued Liabilities relating thereto were determined in accordance
with SAP and Statement of Financial Accounting Standards No. 5 issued by the
Financial Accounting Standards Board.

        (a) Each "EMPLOYEE BENEFIT PLAN" (as defined in Section 3(3) of ERISA),
    bonus, deferred compensation, stock option, stock purchase or other equity
    compensation plan, program or arrangement, each employment, termination or
    severance agreement or plan, incentive compensation or other agreement,

    Acquired Company at any time during the seven-calendar year period
    immediately preceding the Closing Date for the benefit of employees or
    directors of the Company or any other Acquired Company or former employees
    or directors of the Company or any other Acquired Company (collectively, the
    "PLANS") is listed at Section 3.14(a) of the Company Disclosure Schedule.
    Except as may be required by applicable Law or regulatory action, neither
    the Company, nor any Acquired Company, nor any of their respective
    Affiliates, has any Contract, plan or commitment, whether legally binding or
    not, to create any additional Plan or to modify or change any existing Plan.
 
        (b) With respect to each Plan, the Company has made available to, or
    delivered or caused to be delivered to, Parent and its counsel true and
    complete copies of the following documents, as

    applicable, for each respective Plan: (i) all Plan documents, with all
    amendments thereto or, if the Plan is not a written Plan, a description
    thereof; (ii) the current summary plan description with any applicable
    summaries of material modifications thereto as well as any other material

    Plan which is intended to be "QUALIFIED" within the meaning of Section
    401(a) of the Code has received a favorable determination letter from the
    Internal Revenue Service and no event has occurred and no condition exists
    which could reasonably be expected to result in the revocation of any such
    determination. Other than with respect to those matters (the "FBGESOP
    MATTERS") that have been specifically disclosed to the IRS in writing in
    connection with the Company's application, dated as of July 1996, under the
    Employee Plan Closing Agreement Program ("CAP"), the FBGESOP is qualified

    qualification defects in the FBGESOP will not exceed $10,000, and (y)
    provided that the Company corrects the defects in the FBGESOP, the IRS will
    treat the FBGESOP as tax-qualified and in compliance with the requirements
    of Section 401(a) of the Code. Except as disclosed at Section 3.14(c) of the
    Company Disclosure Schedule, other than with respect to the FBGESOP Matters,
    all trusts maintained under the Plans are exempt from taxation under Section
    501(a) of the Code.

    Schedule, no Plan is or has been covered by Section 302 or Title IV of ERISA
    or is or has been subject to the minimum funding requirements of Section 412
    of the Code. No liability has been, or could reasonably be expected to be,
    incurred under Title IV of ERISA (other than for benefits payable in the
    ordinary course of PBGC insurance premiums) or Section 412(f) or (n) of the
    Code by any entity required to be aggregated with the Company or any other
    Acquired Company pursuant to Section 4001(b) of ERISA and/or Section 414(b)
    or (c) of the Code (and the regulations promulgated thereunder) with respect

    (excluding any amounts not yet due).
 
        (f)  Except as disclosed at Section 3.14(f) of the Company Disclosure
    Schedule, neither the Company nor any other Acquired Company nor any other

    in any transaction in connection with any Plan that could reasonably be
    expected to result in the imposition of a material penalty pursuant to
    Section 409 of ERISA or a Tax pursuant to Section 4975(a) of the Code.
    Except as disclosed at Section 3.14(f) of the Company Disclosure Schedule,
    no Plan or related trust owns any securities in violation of Section 407 of
    ERISA.
 
        (g) No Plan provides medical, surgical, hospitalization, death or
    similar benefits (whether or not insured) for employees or former employees
    of the Acquired Companies or any Subsidiary for periods extending beyond
    their retirement or other termination of service, other than (i) coverage
 
                                      I-19

    to severance pay, unemployment compensation or any other payment, except as

    or vesting, or increase the amount of compensation due any such director,
    employee or officer.

failure to so administer and operate such Plan would not reasonably be expected
to have a Material Adverse Effect on the Parent. For purposes of this Agreement,
the term "PARENT PLAN" shall mean each "EMPLOYEE BENEFIT PLAN" (as defined in
Section 3(3) of ERISA), bonus, deferred compensation, stock option, stock
purchase or other equity compensation plan, program or arrangement, each
employment, termination or severance agreement or plan, incentive compensation

its Affiliates pursuant to Section 4001(b) of ERISA and/or Section 414(b) or (c)

Subsidiary has entered into any transactions that would be required to be
disclosed in future public filings under the Exchange Act pursuant to such Item
except for such transactions that are on economic terms no less favorable to

a Person that is not affiliated with Parent, or as have been disclosed in
Section 4.22 of the Parent Disclosure Schedule.
 
    SECTION 4.23  DISCLOSURE.  To Parent's Knowledge, neither the
representations and warranties set forth in this Article IV nor any certificate
required to be furnished by the Parent, Parent Subsidiaries or Sub to the
Company in connection with this Agreement or the transactions contemplated
hereby contains any untrue statement of a material fact concerning Parent,

    registered holders of Company Convertible Debentures prior to September 26,
    1997, in accordance with applicable provisions of the Indenture, and shall
    use its commercially reasonable efforts to cause the redemption of all
    outstanding Company Convertible Debentures in accordance with Section 1102
    of the Indenture (the "REDEMPTION").
 
        (b) In the event that the Company requires cash to pay for any Company
    Convertible Debentures duly surrendered on the Redemption Date (as defined
    in the Indenture), the Company may request in writing not less than ten
    business days in advance of the Redemption Date that Parent purchase, and
    Parent shall purchase, at Parent's election, either such surrendered Company
    Convertible Debentures or a new issue of convertible debentures of the
    Company simultaneously with consummation of the Redemption, in each case, in
    the amount actually redeemed and at a price equal to par value and on terms
    which are substantially identical to the Company Convertible Debentures
    (including interest rate, maturity, conversion price and redemption
    provisions). Notwithstanding the above, Parent may not convert any Company
    Convertible Debenture into shares of Company Common Stock, if and to the
    extent such conversion would require applicable regulatory approvals, if
    any, which Parent has not obtained.

    proper or advisable to consummate and make effective, in the most
    expeditious manner practicable, the Merger and the other transactions
    contemplated by this Agreement, including (i) the obtaining of all necessary
    actions or nonactions, waivers, consents and approvals from Governmental
    Entities and the making of all necessary registrations and filings

    obtaining of all necessary consents, approvals or waivers from third
    parties, (iii) the defending of any lawsuits or other legal proceedings,

<PAGE>
    consummation of the transactions contemplated by this Agreement including
    seeking to have any stay or temporary restraining order entered by any court
    or other Governmental Entity vacated or reversed, and (iv) the execution and
    delivery of any additional instruments necessary to consummate the
    transactions contemplated by, and to fully carry out the purposes of, this
    Agreement; provided, however, that Parent shall not be obligated to take any
    action pursuant to the foregoing if the taking of such action or the
    obtaining of any waiver, consent, approval or exemption is reasonably likely
    to result in the imposition of a condition or restriction of the type
    referred to in Section 8.01(g)(i) and (ii). In connection with and without
    limiting the foregoing, Parent, the Company and their respective Boards of
    Directors shall (i) take all action necessary so that no state takeover
    statute or similar statute or regulation is or becomes applicable to the
    Merger, this Agreement or any other transaction contemplated by this
    Agreement and (ii) if any state takeover statute or similar statute or
    regulation becomes applicable to the Merger, this Agreement or any other
    transaction contemplated by this Agreement, take all action necessary so
    that the Merger and the other transactions contemplated by this Agreement
    may be consummated as promptly as practicable on the terms contemplated by
    this Agreement and otherwise to minimize the effect of such statute or
    regulation on the Merger and the other transactions contemplated by this
    Agreement.
 
        (b) The Company shall give prompt notice to Parent, and Parent or Sub
    shall give prompt notice to the Company, of (i) any representation or
    warranty made by it or contained in this Agreement that is qualified as to
    materiality becoming untrue or inaccurate in any respect or any such
    representation or warranty that is not so qualified becoming untrue or
    inaccurate in any material respect or (ii) the failure by it to comply with
    or satisfy in any material respect any covenant, condition or agreement to
    be complied with or satisfied by it under this Agreement; PROVIDED, HOWEVER,
    that no such notification shall be deemed to cure any breach of the
    representations, warranties, covenants or agreements of the parties or the
    conditions to the obligations of the parties under this Agreement.
 
    SECTION 7.06  INDEMNIFICATION.
 
        (a) Parent shall, to the fullest extent permitted by law, cause the
    Surviving Corporation to honor, and will itself honor, all the Company's
    obligations to indemnify each current or former director and officer of the
    Company or the Company subsidiaries (each, an "INDEMNIFIED PARTY" and
    collectively, the "INDEMNIFIED PARTIES") for acts or omissions by such
    Indemnified Parties occurring prior to the Effective Time to the extent that
    such obligations of the Company exist on the date of this Agreement, whether
    pursuant to the Company's Certificate of Incorporation, By-Laws or
    individual indemnity agreements. Any amendment, repeal or other modification
    to the Certificate of Incorporation or By-Laws of the Company shall not
    affect the obligations of Parent hereunder and shall not adversely affect
    the rights thereunder of Indemnified Parties, unless such modification is
    required by law.
 
        (b) For a period of six years after the Effective Time (it being
    understood that the Company has prepaid all premiums for such policies
    through February 17, 2000), Parent shall cause to be maintained in effect
    the current policies of directors' and officers' liability insurance
    maintained by the Company (provided that Parent may substitute therefor
    policies containing terms with respect to coverage and amounts identical or
    more extensive to the coverage and amounts currently provided by the
    Company's policy) with respect to claims arising from or related to facts or
    events which occurred at or prior to the Effective Time; PROVIDED, HOWEVER,
    that Parent shall not be obligated to make annual premium payments for such
    insurance to the extent such premiums exceed 150% of the annual premiums
    paid as of the date hereof by the Company for such insurance (such 150%
    amount, the "MAXIMUM PREMIUM"). If such insurance coverage cannot be
    obtained at all, or can only be obtained at an annual premium in excess of
    the Maximum Premium, Parent shall maintain the most advantageous policies of
    directors' and officers' insurance obtainable for an annual premium equal to
    the Maximum Premium. The Company represents to Parent that the Maximum
    Premium is $300,000.

by this Agreement, including the Merger, and shall not issue any such press

prior approval of the other party, except as may be required by applicable law,
court process or by obligations pursuant to any listing agreement with any
national securities exchange.
 
    SECTION 7.09  TAX TREATMENT.  Each of Parent and the Company shall use its
reasonable best efforts to (i) not take any action and (ii) not fail to take any
action either before or after the Effective Time which action or failure to act
would prevent, or would be likely to prevent, the Merger from qualifying as a
reorganization within the meaning of Section 368(a) of the Code, and shall each
use their reasonable efforts to obtain the opinion of their respective counsel
referred to in Sections 8.02(d) and 8.03(d) of this Agreement.
 
    SECTION 7.10  AFFILIATES.  Prior to the Closing Date, the Company shall use
its reasonable efforts to deliver to Parent a letter identifying all persons who
are, at the time this Agreement is submitted for approval to the stockholders of
the Company, "AFFILIATES" of the Company (including all directors of the
Company) for purposes of Rule 145 under the Securities Act. The Company shall
use reasonable efforts to cause each such person to deliver to Parent on or
prior to the Closing Date a written agreement substantially in the form attached
hereto as Annex B.
 
    Section 7.11  COMPANY SHAREHOLDER TAX REPRESENTATION.  Immediately prior to
the Closing Date, the Company shall deliver to Parent a schedule identifying all

Company, as appropriate, which counsel may reasonably require in connection with
their opinions under Sections 8.02(d) and 8.03(d) of this Agreement.
 
    SECTION 7.13  STOCK EXCHANGE LISTING.  Parent shall as promptly as
practicable prepare and submit to the Nasdaq a listing application covering the
shares of Parent Common Stock to be issued in connection with the Merger and
this Agreement, and shall use all reasonable efforts to obtain, prior to the
Effective Time, approval for the listing of such shares, subject to official
notice of issuance.
 
    SECTION 7.14  OTHER ACTIONS AND AGREEMENTS.  Except as expressly permitted
by this Agreement, the Company and Parent shall not, and shall not permit any of
their respective subsidiaries to, take any action that would, or that would
reasonably be expected to, result in (i) any of the representations and
warranties of such party set forth in this Agreement that are qualified as to
materiality becoming untrue, (ii) any of such representations and warranties
that are not so qualified becoming untrue in any material respect or (iii) any
of the conditions to the Merger set forth in Article VIII not being satisfied.
Notwithstanding any other provision herein, any consequence of the Company's
good faith, commercially reasonable compliance with Section 5.18 of this
Agreement will not be considered for purposes of determining whether a Material
Adverse Effect on the Company has occurred, whether a representation or warranty
has been breached or whether a condition to Parent's obligations hereunder has
been satisfied, provided Section 3.28 is accurate and the Company is in
compliance with Section 5.18.

the Company to effect the Merger is further subject to the satisfaction or
waiver by the Company on or prior to the Closing Date of the following
conditions:
 
        (a) REPRESENTATIONS AND WARRANTIES. The representations and warranties

    materiality shall be true and correct, and the representations and
    warranties of Parent and Sub set forth in this Agreement that are not so
    qualified shall be true and correct in all material respects, in each case
    as of the date of this Agreement and as of the Closing Date as though made
    on and as of the Closing Date, except to the extent any such representation
    or warranty expressly relates to an earlier date (in which case as of such
    date), and the Company shall have received a certificate signed on behalf of
    Parent by the Chief Executive Officer and the Chief Financial Officer of
    Parent to such effect.
 
        (b) PERFORMANCE OF OBLIGATIONS OF PARENT AND SUB. Parent and Sub shall

    such effect.
 
        (c) OFFICERS' AND DIRECTORS' CERTIFICATES. Parent shall have delivered
    to the Company a certificate, dated the Closing Date and executed by the
    Secretary of Parent, certifying (a) that Parent has duly and validly taken
    all corporate action necessary to authorize its execution and delivery of
    this Agreement and its performance of its obligations under this Agreement,
    and (b) that the resolutions (true and complete copies of which shall be
    attached to the certificate) of the Board of Directors and stockholders of
    Parent with respect to this Agreement and the transactions contemplated
    hereby have been duly and validly adopted and are in full force and effect.
    In addition, Parent shall have delivered to Parent executed copies of the

    Agreement.
 
        (d) TAX OPINION. The Company shall have received an opinion dated the
    Closing Date from Bryan Cave LLP, counsel to the Company, in form and
    substance reasonably satisfactory to the Company, substantially to the
    effect that, on the basis of facts, representations and assumptions set
    forth in such opinion which are consistent with the state of facts existing
    on the Closing Date, the Merger will be treated for United States Federal
    income tax purposes as a reorganization within the meaning of Section 368(a)

    upon (and may incorporate by reference) representations and covenants,
    including those contained in certificates of officers of Parent, the
    Company, Sub and others necessary to give such opinion and to provide
    assurance to stockholders of the Company that they will not recognize gain
    in the Merger, except to the extent cash is received in exchange for
    fractional shares. The specific provisions of each such representation and
    covenant shall be in form and substance reasonably satisfactory to Bryan
    Cave LLP and each such representation and covenant shall be dated on or
    before the date of such opinion and shall not have been withdrawn or
    modified in any material respect.
 
        (e) ABSENCE OF MATERIAL ADVERSE EFFECT ON PARENT OR DELTA. There shall
    not have occurred since the date of this Agreement any event, change, effect
    or development which, individually or in the aggregate, has had or is
    reasonably likely to have, a Material Adverse Effect on Parent.
    Notwithstanding any other provision of this Agreement, it is understood and
    agreed that for all purposes of this Agreement, except for the following
    sentence, no term, representation, warranty, covenant, agreement or other
    provision hereunder shall be deemed to apply to or include Delta Life

    the acquisition of Delta on Parent. In the event Parent acquires Delta,
    there shall not have occurred any event, change, effect or development
    which, individually or in the aggregate, has had or is reasonably likely to
    have, a Material Adverse Effect on Parent.

                                  TERMINATION
 
    SECTION 9.01  TERMINATION.  This Agreement may be terminated and the
transactions contemplated hereby may be abandoned at any time prior to the
Effective Time, upon notice by the terminating party to the other party:
 
        (a) at any time before the Closing, by mutual written agreement of the
    parties; or
 
        (b) at any time by the Company if any of the covenants set forth in
    Article VI or representations and warranties set forth in Article IV shall
    have been breached, or shall not have been performed or complied with, in
    any material respect, at or before the Closing Date and such breach, non-
    performance, or noncompliance has not been cured or eliminated within 30
    calendar days after written notice thereof has been given to Parent, or if a
    condition under Sections 8.01 or 8.03 to the Company's obligations hereunder
    cannot be satisfied prior to the Outside Date;
 
        (c) at any time by Parent if any of the covenants set forth in Article V
    or representations and warranties set forth in Article III shall have been
    breached, or shall not have been performed or complied with, in any material
    respect, before the Closing Date and such breach, non-performance, or
    non-compliance has not been cured or eliminated within 30 calendar days
    after written notice thereof has been given to Company, or if a condition
    under Sections 8.01 or 8.02 to Parent's obligations hereunder cannot be
    satisfied prior to the Outside Date;
 
        (d) by Parent or Company, if this Agreement and the Merger shall have
    failed to receive the requisite approval of the stockholders of (i) the
    Company at the Company Special Meeting, or (ii) Parent at the Parent Special
    Meeting;
 
        (e) at any time after June 30, 1998 (the "OUTSIDE DATE") by the Company
    or Parent, if the transactions contemplated by this Agreement have not been
    consummated on or before such date, provided, that this Agreement shall be
    extended not more than ninety days thereafter if the Merger shall not have
    occurred as a result of the failure to receive the governmental approvals
    set forth in Section 3.06 of the Disclosure Schedule hereto, and such
    failure to obtain approval is not caused by a breach of this Agreement (or
    any representation, warranty, covenant, or agreement included herein) by the
    party electing to terminate pursuant to this clause (e);
 
        (f)  by the Company in accordance with Section 5.16(b);
 
        (g) by Parent if the Board of Directors of the Company shall have
    withdrawn or modified its recommendation of this Agreement or the
    transactions contemplated hereby or approves or recommends any Acquisition
    Proposal; or
 
        (h) by the Company in accordance with Section 2.03(b), unless Parent
    agrees to pay the Adjusted Merger Consideration.
 
    SECTION 9.02  EFFECT OF TERMINATION.
 
        (a) If this Agreement is validly terminated pursuant to Section 9.01
    hereof, this Agreement will forthwith become null and void, and there will
    be no Liability on the part of Company or Parent or Sub (or any of their
    respective Affiliates, officers, directors, employees, agents, consultants,
    or other representatives), except that (i) the provisions of this Section
    9.02, Section 5.18, Section 7.07, the second sentence of Section 7.14, and
    Section 10.02 will continue to apply following any such termination, (ii)
    the provisions relating to confidentiality in Section 7.04 hereof will
    continue to apply following any such termination and (iii) any such
    termination shall be without prejudice to any claim which either party may
    have against the other for breach of this Agreement (or any representation,
    warranty, covenant, or agreement included herein). Without limitation on
    remedies all reasonable out-of-pocket expenses incurred in connection with
    this Agreement and the transactions contemplated hereby by a nonbreaching
    party who terminates this Agreement pursuant to Section 9.01 hereof will be
    reimbursed promptly by the breaching party.

    or Parent pursuant to Section 9.01(d)(i), or (y) by either the Company or
    Parent pursuant to Section 9.01(e) (provided solely in the case of this
    subsection (y) that the Company's stockholders shall not have voted upon the
    approval of this Agreement at the Company Special Meeting prior to the
    Outside Date and such failure to vote was not primarily due to Parent's
    actions or inactions), (i) the Company shall pay to Parent by wire transfer

    a written demand therefor, an amount equal to all reasonable out-of-pocket
    expenses incurred by Parent in connection with this Agreement and the

    time within 24 months following the date of such termination, approves,

    direct or indirect acquisition by any Person of the power to direct the
    voting or disposition of shares of capital stock of the Company representing
    50% or more of the total voting power of all outstanding shares of capital
    stock of the Company, or otherwise resulting in a change in control of the
    Company, the Company shall pay to Parent by wire transfer of immediately
    available funds the amount of $10.8 million, it being understood that such
    amounts are intended to constitute liquidated damages and not as a penalty.
 
        (d) In the event this Agreement is terminated by Parent or the Company
    pursuant to Section 9.01(d)(i) and, prior to the Company Special Meeting,
    (x) the Board of Directors of the Company withdrew or modified its
    recommendation of this Agreement or the transactions contemplated hereby or
    approved or recommended any Acquisition Proposal, and (y) Parent had not
    terminated this Agreement pursuant to Section 9.01(g), the Company shall pay
    to Parent by wire transfer of immediately available funds (A) within two
    Business Days following such termination the amount of $10.8 million, plus
    (B) within two Business Days following receipt of a written demand therefor,
    an amount equal to all reasonable out-of-pocket expenses incurred by Parent

    damages and not as a penalty.

any time before or after the Company Stockholder Approval or the Parent
Stockholder Approval; provided, however, that after the Company Stockholder
Approval or the Parent Stockholder Approval, there shall be made no amendment
that by law requires further approval by such stockholders without the further
approval of such stockholders. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties.
 
    SECTION 9.04  EXTENSION; WAIVER.  At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, or (b) waive any inaccuracies in
the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement, waive compliance with any of the
covenants or conditions contained in this Agreement. Any agreement on the part
of a party to any such extension or waiver shall be valid only if set forth in
an instrument in writing signed on behalf of such party. The failure of any
party to this Agreement to assert any of its rights under this Agreement or
otherwise shall not constitute a waiver of such rights.

    SECTION 10.03  INTERPRETATION.  When a reference is made in this Agreement
to a Section, Article, Annex or Exhibit, such reference shall be to a Section or
Article of, or an Annex or Exhibit to, this Agreement unless otherwise
indicated. In this Agreement, unless a contrary intention appears, (i) the words
"HEREIN", "HEREOF" and "HEREUNDER" and other words of similar import refer to
this Agreement as a whole and not to any particular Article, Section or other
subdivision. The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Whenever the words "INCLUDE", "INCLUDES" or
"INCLUDING" are used in this Agreement, they shall be deemed to be followed by
the words "WITHOUT LIMITATION".
 
    SECTION 10.04  SEVERABILITY.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule or law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that transactions contemplated hereby are fulfilled to the extent
possible.
 
    SECTION 10.05  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties.
 
    SECTION 10.06  ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES.  This
Agreement (including the documents referred to herein) (a) constitute the entire
agreement, and supersede all prior agreements and understandings, both written
and oral, among the parties with respect to the subject matter of this Agreement
and (b) except for the provisions of Sections 1.02 and 7.06 are not intended to
confer upon any person other than the parties any rights or remedies. It is
expressly agreed that the stockholders of neither Parent nor the Company are
intended beneficiaries of any provision hereof.
 
    SECTION 10.07  GOVERNING LAW.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York, regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof, provided that the laws of the state of Kansas shall govern the
effects of the Merger contemplated hereby.
 
    SECTION 10.08  ASSIGNMENT.  Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise by any of the parties without the prior
written consent of the other parties, except that Sub may assign, in its sole
discretion, any of or all its rights, interests and obligations under this
Agreement to Parent or to any direct or indirect wholly owned Parent Subsidiary,
but no such assignment shall relieve Sub of any of its obligations under this
Agreement. Subject to the preceding sentence, this Agreement will be binding
upon, inure to the benefit of, and be enforceable by, the parties and their
respective successors and assigns. Parent shall cause Sub to perform its
obligations hereunder.
 
    SECTION 10.09  ENFORCEMENT; CONSENT TO JURISDICTION.  The parties agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions of this Agreement in any court of
the United States located in the State of New York or in New York state court,
this being in addition to any other remedy to which they are entitled at law or
in equity. In addition, each of the parties hereto (a) consents to submit itself
to the personal jurisdiction of any Federal court located in the State of New
York or any New York state court in the event any dispute arises out of this
Agreement or any of the transactions contemplated by this Agreement, (b) agrees
that it will not attempt to deny or defeat such personal jurisdiction by motion
or other request for leave from any such court and (c) agrees that it will not
initiate any action relating to this Agreement or any of the transactions
contemplated by this Agreement in any court other than a Federal court sitting
in the State of New York or a New York state court.

                          FORM OF AFFILIATE LETTER FOR
                           AFFILIATES OF THE COMPANY
 
                                                               [         ], 1997
 
AmerUs Life Holdings, Inc.
418 Sixth Avenue
Des Moines, Iowa 50309-2407
Ladies and Gentlemen:
 
    I have been advised that as of the date of this letter I may be deemed to be
an "affiliate" of AmVestors Financial Corporation, a Kansas corporation (the
"Company"), as the term "affiliate" is defined for purposes of paragraphs (c)
and (d) of Rule 145 of the rules and regulations (the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act"). Pursuant to the terms of the
Agreement and Plan of Merger dated as of September 19, 1997 (the "Merger
Agreement") among AmerUs Life Holdings, Inc., an Iowa corporation ("Parent"),
AFC Corp., a Kansas corporation ("Merger Sub"), and the Company, the Merger Sub
will be merged with and into the Company (the "Merger"). Capitalized terms used
in this letter without definition shall have the meanings assigned to them in
the Merger Agreement.
 
    As a result of the Merger, I may receive shares of common stock, no par
value, of Parent (the "Parent Shares"). I would receive such Parent Shares in
exchange for shares (or upon exercise of options for shares) owned by me of
common stock, no par value, of the Company (the "Company Shares").
 
    1.  I represent, warrant and covenant to Parent that in the event I receive
any Parent Shares as a result of the Merger:
 
        A.  I shall not make any sale, transfer or other disposition of the
    Parent Shares in violation of the Act or the Rules and Regulations.
 
        B.  I have carefully read this letter and the Merger Agreement and
    discussed the requirements of such documents and other applicable
    limitations upon my ability to sell, transfer or otherwise dispose of the
    Parent Shares, to the extent I felt necessary, with my counsel or counsel
    for the Company.
 
        C.  I have been advised that the issuance of the Parent Shares to me
    pursuant to the Merger has been registered with the Commission under the Act
    on a Registration Statement on Form S-4. However, I have also been advised
    that, because at the time the Merger is submitted for a vote of the
    shareholders of the Company, (a) I may be deemed to be an affiliate of the
    Company and (b) the distribution by me of the Parent Shares has not been
    registered under the Act, I may not sell, transfer or otherwise dispose of
    the Parent Shares issued to me in the Merger unless (i) such sale, transfer
    or other disposition is made in conformity with the volume and other
    limitations of Rule 145 promulgated by the Commission under the Act, (ii)
    such sale, transfer or other disposition has been registered under the Act
    or (iii) in the opinion of counsel reasonably acceptable to Parent, such
    sale, transfer or other disposition is otherwise exempt from registration
    under the Act.
 
                                     I-B-1
<PAGE>
        D.  I understand that Parent is under no obligation to register the
    sale, transfer or other disposition of the Parent Shares by me or on my
    behalf under the Act or, except as provided in paragraph 2(A) below, to take
    any other action necessary in order to make compliance with an exemption
    from such registration available.
 
        E.  I understand that Parent reserves the right to place on the
    certificates for the Parent Shares issued to me, or any substitutions
    therefor, a legend stating in substance:
 
        "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION
    TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE
    SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE
    WITH THE TERMS OF AN AGREEMENT DATED [____________], 1997 BETWEEN THE
    REGISTERED HOLDER HEREOF AND AMERUS LIFE HOLDINGS, INC., A COPY OF WHICH
    AGREE-MENT IS ON FILE AT THE PRINCIPAL OFFICES OF AMERUS LIFE HOLDINGS,
    INC."
 
        F.  I understand that unless a sale or transfer is made in conformity
    with the provisions of Rule 145, or pursuant to a registration statement,
    Parent reserves the right to put the following legend on the certificates
    issued to my transferee:
 
        "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
    RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER
    THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE
    HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY
    DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND
    MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH
    AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF
    1933."
 
        G. Execution of this letter should not be considered an admission on my
    part that I am an "affiliate" of the Company as described in the first
    paragraph of this letter, nor as a waiver of any rights I may have to object
    to any claim that I am such an affiliate on or after the date of this
    letter.
 
    2.  By Parent's acceptance of this letter, Parent hereby agrees with me as
follows:
 
        A.  For so long as and to the extent necessary to permit me to sell the
    Parent Shares pursuant to Rule 145 and, to the extent applicable, Rule 144
    under the Act, Parent shall (a) use its reasonable efforts to (i) file, on a
    timely basis, all reports and data required to be filed with the Commission
    by it pursuant to Section 13 of the Securities Exchange Act of 1934, as
    amended (the "1934 Act"), and (ii) furnish to me upon request a written
    statement as to whether Parent has complied with such reporting requirements
    during the 12 months (or such shorter period as Parent has been subject
    thereto) preceding any proposed sale of the Parent Shares by me under Rule
    145, and (b) otherwise use its reasonable efforts to permit such sales
    pursuant to Rule 145 and Rule 144. Parent hereby represents to me that it
    has filed all reports required to be filed with the Commission under Section
    13 of the 1934 Act during the preceding 12 months (or such shorter period as
    Parent has been subject thereto).
 
                                     I-B-2
<PAGE>
        B.  It is understood and agreed that certificates with the legends set
    forth in paragraphs E and F above will be substituted by delivery of
    certificates without such legend if (i) one year shall have elapsed from the
    date the undersigned acquired the Parent Shares received in the Merger and
    the provisions of Rule 145(d)(2) are then available to the undersigned, (ii)
    two years shall have elapsed from the date the undersigned acquired the
    Parent Shares received in the Merger and the provisions of Rule 145(d)(3)
    are then applicable to the undersigned, or (iii) Parent has received either
    an opinion of counsel, which opinion and counsel shall be reasonably
    satisfactory to Parent, or a "no action" letter obtained by the undersigned
    from the staff of the Commission, to the effect that the restrictions
    imposed by Rule 145 under the Act no longer apply to the undersigned.
 
                                          Very truly yours,
 
                                          --------------------------------------

Board of Directors
AmerUs Life Holdings, Inc.

Des Moines, Iowa 50309-2407
 
Dear Board Members:
 
    You have requested our opinion as to the fairness from a financial point of
view to AmerUs Life Holdings, Inc. (the "Company") of the consideration to be
paid by the Company pursuant to the terms of the Agreement of Merger, dated as
of September 19, 1997 (the "Agreement") by and among AmVestors Financial
Corporation ("AmVestors"), the Company and a wholly owned subsidiary of the
Company ("Sub"), pursuant to which Sub will be merged (the "Merger") with and
into AmVestors.
 
    Pursuant to the Agreement, each share of common stock, no par value
("AmVestors Common Stock"), of AmVestors will be converted, subject to certain
exceptions, into the right to receive an amount of shares of Series A common
stock, no par value ("Company Common Stock"), of the Company, determined as
follows: (a) if the Average Company Share Price (as defined below) is greater
than or equal to $27.00 but less than or equal to $29.75, the number of shares
of Company Common Stock determined by dividing $20.00 by the Average Company
Share Price; (b) if the Average Company Share Price is less than $27.00, 0.7407
shares of Company Common Stock; and (c) if the Average Company Share Price is
greater than $29.75, 0.6724 shares of Company Common Stock (such number of
shares determined pursuant to clauses (a) through (c) above, the "Exchange
Ratio"). The "Average Company Share Price" means the average of the last
reported sales prices per share of Company Common Stock as quoted by The Nasdaq
National Market for the 20 consecutive trading days ending on the trading day
which is ten trading days prior to the consummation of the Merger.
 
    In arriving at our opinion, we have reviewed the draft dated September 19,
1997 of the Agreement. We also have reviewed financial and other information
that was publicly available or furnished to us by the Company and AmVestors,
including information provided during discussions with their respective
managements. Included in the information provided during discussions with the
respective managements were certain financial projections of AmVestors for the
period beginning January 1, 1997 and ending December 31, 2001 prepared by the
management of AmVestors, as well as certain financial projections of the
Company, pro forma for the acquisition of Delta Life Corporation, for the period
beginning January 1, 1997 and ending December 31, 1999 prepared by the
management of the Company. In addition, we have compared certain financial and
securities data of AmVestors with various other companies whose securities are
traded in public markets, reviewed the historical stock prices and trading
volumes of the common stock of AmVestors, reviewed prices and premiums paid in
certain other business combinations and conducted such other financial studies,
analyses and investigations as we deemed appropriate for purposes of this
opinion.
 
    In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
us from public sources, that was provided to us by the Company and AmVestors or
their respective representatives, or that was otherwise reviewed by us. In
particular, we have relied upon the estimates of the management of the Company
of the operating synergies achievable as a result of the Merger. With respect to
the financial projections supplied to us, we have assumed that they have been
reasonably prepared on the basis reflecting the best currently available
estimates and judgments of the management of the Company and AmVestors as to the
future

information reviewed by us.
 
    Our opinion is necessarily based on economic, market, financial and other
conditions as they existed on, and on the information made available to us as
of, the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion herein as to the
prices at which Company Common Stock will actually trade at any time. Our
opinion does not address the relative merits of the Merger and the other
business strategies being considered by the Company's Board of Directors, nor
does it address the Board's decision to proceed with the Merger. Our opinion
does not constitute a recommendation to any shareholder as to how such
shareholder should vote on the proposed transaction.
 
    Donaldson, Lufkin, & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. DLJ has performed investment
banking and other services for the Company in the past and has been compensated
for such services. In January 1997, DLJ co-managed an initial public offering of
Company Common Stock and received usual and customary underwriters compensation.
In addition, in April 1996, DLJ advised Financial Benefit Group, Inc. in its
sale to AmVestors and received usual and customary compensation for such
services.
 
    Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the Exchange Ratio is fair to the Company from a financial
point of view.

Ladies and Gentlemen:
 
You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of Common Stock, no par value (the
"Shares"), of AmVestors Financial Corporation (the "Company") of the Exchange
Ratio (as defined below) pursuant to the Agreement and Plan of Merger, dated as
of September 19, 1997, among AmerUs Life Holdings, Inc. ("AmerUs"), Joe Corp., a
wholly-owned subsidiary of AmerUs, and the Company (the "Agreement"). Pursuant
to the Agreement, the Company will merge with Joe Corp. (the "Merger") and each
outstanding Share will be converted into the right to receive a number of shares
of Series A Common Stock, no par value (the "AmerUs Common Stock"), of AmerUs,
computed, subject to adjustment, such that each Share will be exchanged for at
least 0.6724 shares of AmerUs Common Stock, as set forth in the Agreement (the
"Exchange Ratio").
 
Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. We are familiar with
the Company having acted as its financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement. We also
have provided certain investment banking services to AmerUs from time to time,
including having acted as its financial advisor on the formation of a mutual
holding company in 1996, having acted as lead manager of the initial public
offering of AmerUs Common Stock in January 1997 and as lead manager of an
issuance of the Capital Securities of AmerUs Capital I, an affiliate of AmerUs,
in January 1997, and we may provide investment banking services to AmerUs in the
future.
 
In connection with this opinion, we have reviewed, among other things, the
Agreement; an actuarial appraisal dated May 13, 1997 of the insurance operations
of the Company prepared by Actuarial Resources Corporation (the "Appraisal");
Annual Reports to Stockholders and Annual Reports on Form 10-K of the Company
for the five years ended December 31, 1996; the Registration Statement on Form
S-1 of AmerUs, dated January 28, 1997; Statutory Annual Statements filed by
American Investors Life Insurance Company, Financial Benefit Life

Insurance Company and AmerUs Life Insurance Company (including the predecessor
companies Central Life Assurance Company and American Mutual Life Insurance
Company), with the Insurance Departments of the States under which they are
respectively organized for the five years ended December 31, 1996; certain
interim statutory reports filed by American Investors Life Insurance Company,
Financial Benefit Life Insurance Company and AmerUs Life Insurance Company with
the Insurance Departments of the States under which they are respectively
organized; certain interim reports to stockholders and Quarterly Reports on Form
10-Q of the Company and AmerUs; certain other communications from the Company
and AmerUs to their respective stockholders; certain information regarding the
reserves of AmerUs; certain internal financial analyses and forecasts for the
Company prepared by the management of the Company; and certain internal
financial analyses and forecasts for AmerUs and the Company prepared by the
management of AmerUs. We have held discussions with members of the senior
management of the Company and AmerUs regarding the strategic rationale for, and
the potential benefits of, the Merger and the past and current business
operations, financial condition and future prospects of their respective
companies. We also have discussed the pro forma impact of the Merger, as well as
the pending acquisition by AmerUs of Delta Life and Annuity Company ("Delta
Life") with the management of AmerUs (the "Pro Forma Information"), as well as
certain other financial analyses provided to us by AmerUs regarding Delta Life.
In addition, we have reviewed the reported price and trading activity for the
Shares and the AmerUs Common Stock, compared certain financial and stock market
information for the Company and AmerUs with similar information for certain
other companies the securities of which are publicly traded, reviewed the
financial terms of certain recent business combinations in the life insurance
and annuities industries specifically and in other industries generally and
performed such other studies and analyses as we considered appropriate.
 
We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us, including the information furnished by the
Company and AmerUs relating to reserves and related items, and have assumed such
accuracy and completeness for purposes of rendering this opinion. In that
regard, we have assumed, with your consent, that the financial estimates of the
Company and AmerUs, including, without limitation, the Pro Forma Information
provided to us by AmerUs have been reasonably prepared and reflect the best
currently available judgments of the Company and AmerUs and that such estimates
will be realized in the amounts and the times contemplated thereby. We are not
actuaries and our services did not include actuarial determinations or
evaluations by us or an attempt to evaluate actuarial assumptions. In addition,
we have not made an independent evaluation or appraisal of the assets and
liabilities of the Company, AmerUs, Delta Life or any of their subsidiaries and,
except for the Appraisal and certain information related to the reserves of the
Company and AmerUs, we have not been furnished with any such evaluation or
appraisal.

Our advisory services and the opinion expressed herein are provided for the
information and assistance of the Board of Directors of the Company in
connection with its consideration of the transaction contemplated by the
Agreement and such opinion does not constitute a recommendation as to how any
holder of Shares should vote with respect to such transaction.
 
Our opinion is necessarily based upon financial, economic, market and other
conditions as they exist and can be evaluated on the date hereof. We are not
expressing any opinion as to the value of the AmerUs Common Stock when issued to
the holders of the Shares pursuant to the Agreement or to the prices at which
such AmerUs Common Stock will trade subsequent to the Merger.
 
Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair from a financial point of view to the
holders of Shares.
 
Very truly yours,

                                       PART II
                        INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20:  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 851 of the Iowa Business Corporation Act ("IBCA") provides that a
corporation has the power to indemnify its directors against liabilities and
expenses incurred by reason of such person serving in the capacity of director
or officer, if such person has acted in good faith and in a manner reasonably
believed by the individual to be in or not opposed to the best interests of the
corporation, and in any criminal proceeding if such person had no reasonable
cause to believe the individual's conduct was unlawful.  The foregoing indemnity
provisions notwithstanding, in the case of actions brought by or in the right of
the corporation, no indemnification shall be made to such director with respect
to any matter as to which such individual has been adjudged to be liable to the
corporation unless, and only to the extent that, a court determines that
indemnification is proper under the circumstances.  Indemnification, where
proper, is limited to reasonable expenses incurred in connection with such
proceedings.

    Section 852 of the IBCA provides that, unless limited by its articles of
incorporation, a corporation must indemnify a director who successfully defends
himself in a proceeding to which the director was a party by nature of the
director's role as director.

    Section 853 of the IBCA provides that a corporation may pay for or
reimburse the reasonable expenses incurred by a director who is a party to
proceeding prior to final disposition where (1) the director supplies the
corporation with written affirmation that the director has acted in good faith
pursuant to Section 851, (2) the director agrees, in writing, to repay the
advance if it is determined that the director did not meet the required standard
of conduct, and (3) the facts known at the time of reimbursement would not
preclude indemnification.

    Section 854 of the IBCA specifies, where a corporation's articles of
incorporation do not provide otherwise, the manner in which a director may apply
for indemnification to the court conducting the proceeding.

    Section 855 of the IBCA specifies the process that a corporation must use
in determining whether indemnification of a director is permissible because the
director has met the standard of conduct required by Section 851.

    Section 856 of the IBCA provides that, unless a corporation's articles of
incorporation provide otherwise, an officer of a corporation who is not a
director is entitled to indemnification to the same extent as a director.

    Section 857 of the IBCA authorizes the purchase and maintenance of
insurance to indemnify an individual who is or was a director, officer,
employee, or agent of the corporation.

    Article VIII of the Amended and Restated Articles of Incorporation of the
Registrant (the "Articles") provides in part that the Registrant shall indemnify
its directors to the fullest extent possible under the IBCA, and the
Registrant's Bylaws extend the same indemnity to its officers.  The Articles
also provide that no directors shall be liable to the Registrant or its
shareholders for monetary damages for breach of the individual's fiduciary duty
as a director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or its shareholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for any transaction in which the director derived an improper
personal benefit, or (iv) under the IBCA provisions relating to improper
distributions.

    The Registrant maintains a directors' and officers' liability insurance
policy to insure against losses arising from claims made against its directors
and officers, subject to the limitations and conditions as set forth in the
policies.  In

                                         II-1
<PAGE>

addition, the Registrant has entered into indemnification agreements with its
directors and certain of its executive officers providing for the
indemnification of such persons as permitted by the Articles and Iowa law.

    (a)  EXHIBITS

ITEM 22.  UNDERTAKINGS

(a) The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933.

         (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar amount of securities offered would not
exceed that which was registered) and any deviation from the low or high and of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price represent no more than a 20 percent change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

         (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

    (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein,and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

                                         II-2
<PAGE>

(b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDe offering thereof.

(c)(1)  The undersigned Registrant hereby undertakes as follows:  that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

    (2)  The Registrant undertakes that every prospectus:  (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

(d)  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

(e)  The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form S-4, within one business day of receipt
of such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

(f)  The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Gentlemen:

    The following opinion is furnished in connection with the Registration 
Statement on Form S-4 (the "Registration Statement") being filed by AmerUs 
Life Holdings, Inc., an Iowa corporation (the "Company") under the Securities 
Act of 1933, as amended, relating to the issuance of shares of the Class A 
Common Stock, no par value, of the Company (the "Class A Common Stock") in 
connection with:

    (a)  the proposed merger (the "Merger") of AFC Corp., a Kansas 
         corporation and a wholly-owned subsidiary of the Company, with and 
         into AmVestors Financial Corporation, a Kansas corporation 
         ("AmVestors"), in accordance with the terms of the Amended and 
         Restated Agreement and Plan of Merger, dated as of September 19, 
         1997, as amended and restated as of October 8, 1997, by and among 
         the Company, AFC Corp. and AmVestors (the "Merger Agreement", a copy 
         of which is attached as Annex I to the Joint Proxy 
         Statement/Prospectus forming a part of the Registration Statement);

    (b)  the exercise, following consummation of the Merger, of the 
         outstanding AmVestors warrants identified in Section 3.03(c) of the 
         Merger Agreement (the "Assumed Warrants").

<PAGE>

    I have examined originals or copies, certified or otherwise identified to
my satisfaction, of such corporate records and other documents, and have
conducted such other investigations of fact and law, as I have deemed necessary
or advisable for purposes of this opinion.  For purposes of this opinion, I have
assumed that the Assumed Warrants were duly authorized and issued, are in full
force and effect and constitute the legal, valid and binding obligations of
AmVestors in accordance with their terms.

    Upon the basis of the foregoing, I am of the opinion that:

    1.   The Class A Common Stock to be issued in connection with the Merger
         has been duly authorized and, subject to the Registration Statement
         becoming effective, when issued in accordance with the terms of the
         Merger Agreement, the Class A Common Stock will be legally issued,
         fully paid and nonassessable.

    2.   Upon consummation of the Merger, the Class A Common Stock issuable
         upon exercise of the Assumed Warrants has been duly authorized and,
         subject to the Registration Statement becoming effective, when issued
         in accordance with the terms of the Assumed Warrants, as applicable,
         and upon receipt by the Company of the consideration therefor, the
         Class A Common Stock will be legally issued, fully paid and
         nonassessable.

    I consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to me in the Joint Proxy Statement/Prospectus
forming a part of the Registration Statement.

                        Very truly yours,

evidenced under this Agreement constitutes a loan and not a purchase and sale,
it is the intent of the parties hereto that this Agreement shall constitute a
security agreement under applicable law and that Seller has granted a first
priority security interest in all of Seller's right, title and interest in and
to each Mortgage Loan and all proceeds thereof.  To protect the interests of
Buyer in the event that the transactions contemplated hereunder are deemed to
constitute a pledge of security for a loan, Seller shall execute or cause to be
executed such documents and take or cause to be taken such actions as may be
necessary to maintain and preserve the security interest of Buyer granted
pursuant to this Section 2.7.  Seller hereby appoints Buyer its attorney-in-fact

statement, instrument of further assurance or other document or to take such
other action, as may be required under this Section 2.7, and such appointment is
irrevocable and coupled with an interest.

                            REPRESENTATIONS AND WARRANTIES

    Section 3.1.   GENERAL REPRESENTATIONS AND WARRANTIES OF SELLER.  As of
each Closing Date, Seller hereby makes each of the following representations and
warranties to Buyer:

    (a)     Seller is a federal savings bank, duly organized and validly
            existing under the laws of the United States of America which has
            the power to own its assets and to transact the business in which
            it is presently engaged.  To the extent required, Seller is duly
            qualified in good standing under the laws the State of Iowa and
            each jurisdiction where its ownership of property or the conduct of
            its business requires such qualification and where the failure to
            be so qualified would have a material adverse affect on the
            business and assets of Seller, taken as a whole.

    (b)     Seller has the requisite power and authority to execute and deliver
            this Agreement  and to consummate the transactions contemplated
            hereby.  Seller has been duly authorized by proper action to
            approve the execution and delivery of this Agreement, the sale of
            the Mortgage Loans to Buyer according to the terms of this
            Agreement and the execution and delivery to Buyer of all
            instruments


                                          7
<PAGE>

            appropriate and necessary for the transfer and sale of the Mortgage
            Loans to Buyer.  This Agreement has been duly executed and
            delivered by Seller and constitutes a legal, valid and binding
            obligation of Seller, enforceable against Seller in accordance with
            its terms, subject only to bankruptcy and insolvency laws and
            similar laws affecting creditors' rights generally and equitable
            principles of law.

    (c)     Neither the execution and delivery of this Agreement nor the
            consummation of the transaction contemplated by this Agreement will
            conflict with or result in a breach of, or constitute a default
            under, any instrument or agreement to which Seller is a party, or
            by which it is bound, nor be in violation of any governmental
            decree, order or ruling as to which Seller may be bound.

    (d)     The consummation of the transactions contemplated by this Agreement
            are in the ordinary course of business of Seller, and the transfer,
            assignment and conveyance of the Notes and the Mortgages by Seller
            pursuant to this Agreement are not subject to the bulk transfer or
            similar statutory provisions in effect in any applicable
            jurisdiction.

    (e)     No action, suit, proceeding or governmental investigation or
            inquiry is currently pending or, to the knowledge of Seller,
            threatened against Seller which, if adversely determined, would
            have a material adverse effect on the business, combined assets or
            financial condition of Seller or on the Mortgage Loans or would
            prevent the consummation of the transactions contemplated by this
            Agreement.

    (f)     Seller does not believe, nor does it have any reason or cause to
            believe, that it cannot perform each and every covenant contained
            in this Agreement.  Seller is solvent, and the sale of the Mortgage
            Loans will not cause Seller to become insolvent.  The sale of the
            Mortgage Loans is not undertaken with the intent to hinder, delay
            or defraud any creditor of Seller.

    (g)     No consent, approval, authorization or order of any court or
            governmental agency or body is required for the execution, delivery
            and performance by Seller of or compliance of Seller with this
            Agreement, or, if required, such consent, approval, authorization
            or order has been obtained prior to the applicable Closing Date.

    (h)     Seller has not, in connection with this transaction, incurred any
            obligation, made any commitment or taken any action which might
            result in a claim against or an obligation by Buyer to pay a sales
            brokerage commission, finder's fee or similar fee with respect to
            this Agreement.

    (i)     With respect to approximately ninety percent (90%) of the Mortgage
            Loans, by aggregate principal balance as of the Cut-Off Date, as of
            the date of origination and, to the best of Seller's knowledge, as
            of the Closing Date, the Obligor occupies the related Mortgaged
            Property as the Obligor's primary residence.  The sole basis for
            such representation is either (i) a representation by the Obligor
            at origination of the Mortgage Loan that the Mortgaged Property
            will be used for a


                                          8
<PAGE>

            period of at least six months every year, or that the Obligor
            intends to use the Mortgaged Property, as the primary residence, or
            (ii) that the address of the Mortgaged Property is the Obligor's
            mailing address as reflected in Seller's records.  No more than ten
            percent (10%) of the Mortgaged Properties, by aggregate principal
            balance as of the Cut-Off Date, are non-owner occupied, and none of
            the Mortgaged Properties are rental properties.  No Mortgage Loan
            was made for the purpose of original construction or made to
            facilitate an exchange of property by the Obligor.

    Section 3.2.   REPRESENTATIONS AND WARRANTIES OF SELLER REGARDING THE
MORTGAGE LOANS. With respect to each Mortgage Loan, as of the Closing Date on
which such Mortgage Loan is sold to Buyer, Seller hereby makes the following
representations and warranties to Buyer:

    (a)     Seller has clear, marketable and valid title and is the owner of
            the Mortgage Loan and the indebtedness evidenced by the Note, and
            has the unqualified right to transfer title to the Mortgage Loan
            and all documents and instruments in connection therewith to Buyer,
            free of any encumbrance, lien, pledge or interest of any third
            Person whatsoever.

    (b)     The information regarding the Mortgage Loan contained in the
            Schedule of Assets is true and correct in all respects as of the
            Cut-Off Date.

    (c)     The Note, the Mortgage and all instruments and supporting
            documentation evidencing, securing or otherwise related to the
            Mortgage Loan are genuine, valid and enforceable according to their
            terms, subject only to bankruptcy and insolvency laws, or similar
            laws affecting creditors' rights generally and equitable principles
            of law, and all signatures thereon are genuine.

    (d)     The Mortgage Loan was underwritten in compliance with Seller's
            underwriting guidelines attached hereto as EXHIBIT B; provided,
            however, that a default on the Mortgage Loan shall not, by itself,
            be deemed to infer that such Mortgage Loan does not comply with
            Seller's underwriting guidelines.

    (e)     The Mortgage Loan is not contractually delinquent by more than
            thirty (30) days, nor has it been delinquent for more than sixty
            (60) days at any time within the twelve (12) month period preceding
            the Closing Date, nor has the Mortgage Loan at any time been
            renewed for the purpose of concealing the delinquency of any
            Persons obligated thereon.

    (f)     As to the Mortgage Loan, all applicable federal, state and local
            laws, rules and regulations have been complied with, including
            without limitation the Real Estate Settlement Procedures Act, the
            Equal Credit Opportunity Act, the Federal Truth-in-Lending Act
            (Regulation Z), the Fair Credit Reporting Act, the Flood Disaster
            Protection Act, licensing laws, federal and state usury laws, and
            any other applicable laws, rules or regulations which prohibit or
            limit fees, charges or costs which lenders may impose on borrowers.


                                          9
<PAGE>

    (g)     The Mortgage has been duly recorded and constitutes a valid and
            legally enforceable lien on the Mortgaged Property in accordance
            with the laws of the jurisdiction in which the Mortgaged Property
            is located, and the Mortgaged Property is not subject to any other
            recorded liens having priority over the lien of the Seller, except
            for Permited Exceptions and other liens as are approved in writing
            by Buyer.

    (h)     The Assignment relating to the Mortgage is in recordable form and
            is acceptable for recording under the laws of the jurisdiction in
            which the Mortgaged Property is located.

    (i)     The Mortgage Loan and the Note are free from any right of
            rescission, defense (including the defense of usury), off-set,
            counterclaim or recoupment assessable by the Obligor.  No right of
            rescission, defense, off-set, counterclaim or recoupment has been
            asserted to Seller or, to Seller's knowledge, to any other Person.

    (j)     The terms of the Note and the Mortgage have not been impaired,
            waived, altered or modified in any respect, except by a written
            instrument which, if necessary to protect the interests of Buyer,
            has been recorded.

    (k)     The Note, the Mortgage and all other documents contained in the
            Mortgage Loan File are on FNMA or FHLMC uniform instruments or on
            forms acceptable to FNMA or FHLMC or reasonably acceptable to
            Buyer.

    (l)     Seller has made no representations to the Obligor that are
            inconsistent with the Note, the Mortgage or any other mortgage
            instrument concerning the Obligor.

    (m)     There is no payment default, and, to the best of Seller's
            knowledge, there is no other default, breach, violation or event of
            acceleration existing under the Note or the Mortgage and no event
            which, with the passage of time or with notice and the expiration
            of any applicable grace or cure period, would constitute a default,
            breach, violation or event of acceleration, and Seller has not
            waived any default, breach, violation or event of acceleration.

    (n)     The Mortgage contains customary provisions such as to render the
            rights and remedies of the holder thereof adequate for the
            realization against the Mortgaged Property of the benefits of the
            security provided thereby, including (i) in the case of a Mortgage
            designated as a deed of trust, by trustee's sale, and (ii)
            otherwise by judicial foreclosure.

    (o)     Neither the Mortgage nor the Note has been satisfied, canceled,
            subordinated or rescinded, in whole or in part, and the Mortgaged
            Property has not been released from the lien of the Mortgage, in
            whole or in part, nor has any instrument been executed that would
            effect any such release, cancellation, subordination or rescission.
            Seller has not waived performance by the Obligor of any action,
            where the Obligor's failure to perform such action would cause the
            Mortgage


                                          10

            Loan to be in default, nor has Seller waived any default resulting
            from the action or inaction by the Obligor.

    (p)     The Mortgage Loan has been closed and the proceeds of the Mortgage
            Loan have been fully disbursed and there is no requirement for
            future advances with respect thereto.  All costs, fees and expensed
            incurred in making or closing the Mortgage Loan and the recording
            of the Mortgage have been paid, and the Obligor is not entitled to
            any refund of any amounts paid or due under the Note or the
            Mortgage.

    (q)     If required by Seller's underwriting guidelines, the Mortgage Loan
            is covered by either (i) an attorney's opinion of title and
            abstract of title the form and substance of which is acceptable to
            FNMA or (ii) an ALTA lender's title policy or other generally
            acceptable form of policy of insurance issued by a title insurer
            qualified to do business in the jurisdiction where the Mortgaged
            Property is located, insuring Seller, its successor and assigns, as
            to the appropriate first or second priority lien of the Mortgage,
            in the original principal amount of the Mortgage Loan, subject only
            to Permitted Exceptions. No claims have been made under any such
            lender's title insurance policy, and Seller has not taken any
            action or failed to take any action which would impair the coverage
            of any such lender's title insurance policy.

    (r)     To the best of Seller's knowledge, there are no mechanic's or
            similar liens or claims which have been filed for work, labor or
            material (and no rights outstanding that by law could give rise to
            such liens) affecting the Mortgaged Property which are or may be
            liens prior to or equal or coordinate with the lien of the
            Mortgage.

    (s)     In the event that the Mortgage is a deed of trust, a trustee,
            authorized and duly qualified under applicable law to serve as
            such, has been properly designated and currently so serves and is
            named in the Mortgage.

    (t)     If required pursuant to Seller's underwriting guidelines, the
            Mortgage Loan File contains an appraisal of the Mortgaged Property
            signed prior to the approval of the application for the Mortgage
            Loan by a qualified appraiser who (i) is licensed in the state
            where the Mortgaged Property is located; (ii) has no interest,
            direct or indirect, in the Mortgaged Property or in any loan on the
            security thereof; and (iii) does not receive compensation that is
            affected by the approval or disapproval of the Mortgage Loan.  All
            such appraisals comply in all material respects with applicable
            federal and state laws and regulations.

    (u)     The Obligor has not requested from Seller, and Seller has no
            knowledge of any request for, any relief for the Obligor under the
            Soldiers' and Sailors' Civil Relief Act of 1940.

    (v)     To the best of Seller's knowledge, there exists no violation of any
            local, state, or federal environmental law, rule or regulation in
            respect of the Mortgaged Property which violation has or could have
            a material adverse effect on the market value


                                          11
<PAGE>

            of such Mortgaged Property.  Seller has no knowledge of any pending
            action or proceeding involving the Mortgaged Property in which
            compliance with any environmental law, rule or regulation is in
            issue; and, to the best of Seller's knowledge, nothing further
            remains to be done to satisfy in full all requirements of each such
            law, rule or regulation constituting a prerequisite to the use and
            enjoyment of such Mortgaged Property.

    (w)     The Mortgaged Property is a fee simple estate and consists of a
            parcel of real property with (i) a single family residence, (ii)  a
            two-to four-family dwelling, (iii) an individual condominium unit
            in a low-rise or high-rise condominium project, or (iv) an
            individual unit in a planned unit development erected thereon.

    (x)     All improvements upon the Mortgaged Property are insured by a
            blanket hazard insurance policy which is issued by an insurer and
            in an amount acceptable to FNMA against loss by fire and such other
            risks (excluding mud slides and earthquakes) as are usually insured
            against in the broad form of extended coverage hazard insurance
            from time to time available, including flood hazards if upon
            origination of the Mortgage Loan, the Mortgaged Property was
            located in an area identified in the Federal Register by the
            Federal Emergency Management Agency as having special flood hazards
            (and if flood insurance was required by federal regulation).
            Seller has not engaged in and has no knowledge of the Obligor's or
            any subservicer's having engaged in, any act or omission which
            would impair the coverage of any such policy, the benefits of the
            endorsement provided for therein or the validity and binding effect
            of either.

    (y)     No taxes, impositions, fees or assessments in the nature of a tax
            shall accrue against or be collected from Buyer on the Mortgage
            Loan by reason of the purchase by Buyer of the Mortgage Loan.

    (z)     The Mortgage has never been assigned to any third party.

    (aa)    Seller has not initiated an action of foreclosure against nor
            obtained a judgment of foreclosure against the related Mortgaged
            Property.

    (bb)    To the best of Seller's knowledge: (i) neither the Mortgaged
            Property nor any improvements thereon is the subject of pending
            insurance claims;  (ii) the Obligor is not deceased, and neither
            the Obligor nor the Mortgage Loan is the subject of, or are in any
            way affected by, any pending legal proceeding; and (iii) the
            Mortgaged Property is not the subject matter of a pending sale to a
            third party by the Obligor, nor is the Mortgage Loan the subject
            matter of a payoff in progress.

    (cc)    None of the credits applied to the Mortgage Loan has been
            gratuitous or given by Seller for considerations other than the
            payment of money, and all amounts represented to be payable on
            Mortgage Loan are, in fact, payable in accordance with the
            provisions of the Note.


                                          12

    (dd)    The Mortgage contains usual and customary provisions for the
            acceleration of amounts outstanding on the Note in the event that
            the Mortgaged Property is sold.

    (ee)    Seller has not received notice of: (i) any proceeding for the total
            or partial condemnation of the Mortgaged Property; (ii) any
            proceeding for relief by or against any Obligor under federal or
            state bankruptcy or insolvency laws; or (iii) any subsequent,
            intervening mortgage, lien, attachment, lis pendens or other
            encumbrance affecting the Mortgaged Property, other than Permitted
            Exceptions.

    (ff)    The Mortgage Loan contains no provisions pursuant to which payments
            are (i) paid or partially paid with funds deposited in any separate
            account established by Seller, Obligor or any Person on behalf of
            Obligor; (ii) paid by any source other than Obligor; or (iii)
            contains any similar provisions which may constitute a "buydown" of
            the interest rate.

    (gg)    The consideration received by Seller upon the sale of the Mortgage
            Loan constitutes fair consideration and reasonably equivalent value
            for the Mortgage Loan.

    (hh)    Seller used no adverse selection procedures in selecting the
            Mortgage Loan from among the outstanding loans in Seller's
            portfolio.

    (ii)    The Combined Loan to Value Ratio on the Mortgage Loan does not
            exceed one hundred percent (100%).

    (jj)    The related Mortgage Loan File contains each of the documents and
            instruments specified to be included therein, with such exceptions
            as set forth in Section 2.6 hereof. 

    (kk)    The Mortgaged Property is neither a mobile home nor a manufactured
            housing unit that is not permanently attached to its foundation.

    (ll)    The Mortgage Loan has no shared appreciation feature or other
            contingent interest feature.

    (mm)    The Mortgage Loan is secured by either a first or a second lien. 
            Seller has not received a notice of default of any first mortgage
            loan related to a Mortgaged Property which has not been cured.

    (nn)    The indebtedness evidenced by the Mortgage Loan is not convertible
            to an ownership interest in the related Mortgaged Property or the
            related Obligor.

    (oo)    No Mortgage related to the Mortgage Loan provides that the related
            Mortgaged Property secures any other promissory note or obligation
            expressly described in such Mortgage other than another Mortgage
            Loan.


                                          13

    (pp)    The Mortgage Loan does not permit the Obligor to require the
            release of all or a portion of the Mortgaged Property from the lien
            of the related Mortgage other than upon payment in full of the
            Mortgage Loan.

    (oo)    The Mortgage Loan does not provide for deferred interest.

    Section 3.3.   REPRESENTATIONS AND WARRANTIES OF BUYER.  Buyer hereby makes
the following representations and warranties to Seller as of each Closing Date:

    (a)     Buyer is a corporation, duly organized and validly existing under
            the laws of the State of Iowa, which has the power to own its
            assets and to transact the business in which it is presently
            engaged.  Buyer is duly qualified and in good standing under the
            laws of the State of Iowa and each jurisdiction where its ownership
            of property or the conduct of its business requires such
            qualification and where the failure to be so qualified would have a
            material adverse affect on the business and assets of Buyer, taken
            as a whole.

    (b)     Buyer 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 and the consummation of the transactions
            contemplated hereby have been duly and validly authorized by all
            necessary corporate action, and no other corporate proceedings on
            the part of Buyer are necessary to authorize this Agreement or to
            consummate the transactions contemplated hereby.  This Agreement
            has been duly executed and delivered by Buyer and constitutes a
            legal, valid and binding obligation of Buyer, enforceable against
            Buyer in accordance with its terms, subject only to bankruptcy and
            insolvency laws and similar laws affecting creditors' rights
            generally and equitable principles of law.

    (c)     Neither the execution and delivery of this Agreement, nor the
            consummation of the transaction contemplated by this Agreement will
            conflict with or result in a breach of, or constitute a default
            under, any instrument or agreement to which Buyer is a party, or by
            which it is bound, or be in violation of any governmental decree,
            order or ruling as to which Buyer may be bound.

    (d)     No action, suit, proceeding or governmental investigation or
            inquiry is currently pending or, to the knowledge of Buyer,
            threatened against Buyer which, if adversely determined, would have
            a material adverse effect on the business, combined assets or
            financial condition of Buyer or on the Mortgage Loans or would
            prevent the consummation of the transactions contemplated by this
            Agreement.

    (e)     Buyer does not believe, nor does it have any reason or cause to
            believe, that it cannot perform each and every covenant contained
            in this Agreement.  Buyer is solvent, and the purchase of the
            Mortgage Loans will not cause Buyer to become insolvent. 


                                          14

<PAGE>



    (f)     No consent, approval, authorization or order of any court or
            governmental agency or body is required for the execution, delivery
            and performance by Buyer of or compliance of Buyer with this
            Agreement, or, if required, such consent, approval, authorization
            or order has been obtained prior to the applicable Closing Date.
    
    (g)     Buyer has not, in connection with this transaction, incurred any
            obligation, made any commitment or taken any action which might
            result in a claim against or an obligation by Seller to pay a sales
            brokerage commission, finder's fee or similar fee with respect to
            this Agreement.

                   representations made by Seller in this Agreement, to the
                   extent that such untruthfulness does not arise by reason of

                   covenants or provisions of this Agreement, to the extent
                   that the breach has a material adverse effect and to the
                   extent that such breach does not arise by reason of Buyer's
                   actions; or

            (iii)  Any action taken by Seller with respect to any Mortgage Loan
                   prior to the Closing Date for such Mortgage Loan.

                   to consult with the other party regarding the defense of a
                   claim against it.

    Section 5.2.   BUYER'S INDEMNIFICATION. (a) Buyer shall indemnify Buyer and

    (b)     The foregoing provisions of this Section 5.2 shall be subject to
            the following conditions:

            (i)    Seller must promptly notify Buyer upon commencement of any

    Section 5.3.  CURE OF BREACH, REPURCHASE OR SUBSTITUTION BY SELLER. In 
the event of a breach of any of Seller's representations, warranties or 
covenants, in addition to the remedies specified in Section 5.1 above, Buyer, 
as assignee of any purchased Mortgage Loan, may demand, for the twenty-four 
(24) months immediately following the Closing Date for such Mortgage Loan 
(the "Substitution Period"), that Seller, at Seller's option, either:  (a) 
cure the breach or (b) substitute a loan of equal value subject to all the 
terms and conditions of this Agreement.  After the Substitution Period, in 
the event of a breach of any of Seller's representations, warranties or 
covenants, in addition to the remedies specified in Section 5.1 above, Buyer 
may demand that Seller, at Seller's option, either: (a) cure the breach or 
(b) repurchase such Mortgage Loan forthwith, for the then unpaid principal 
balance plus accrued interest. Seller shall have a period of ten (10) 
Business Days from its receipt of written notice from Buyer of a breach to 
take such action demanded by Buyer as Seller may elect, but if Seller elects 
to cure the breach and the nature of the breach giving rise to the obligation 
of Seller to cure the breach is such that it cannot be cured immediately, 
Seller shall have the right to proceed diligently to effect a cure, which 
shall in no event be effectuated later than thirty (30) days from the date of 
Seller's receipt of notice of the breach.  If Seller has not cured the breach 
after this thirty (30) day period lapses, Seller shall repurchase or

RE: Master Commitment for the Purchase of Residential Mortgage Loans

Dear Gentlepersons:

This letter and the exhibits represent an agreement (the "Master Commitment") 
between AmerUs Mortgage ("Seller") and AmerUs Life ("Purchaser"). Under this 
Master Commitment, Seller and Purchaser agree to the one hundred percent 
whole loan sale and purchase of first lien residential mortgage loans. The 
total amount of the Master Commitment will be $200,000,000. The terms and 
conditions of this Master Commitment will expire on March 1, 1998, or upon 
the delivery and purchase of the Master Commitment amount. The mortgage loans 
must meet the terms and conditions as stated on the attached appendices.

SECTION 1. LOAN PROGRAMS.

Eligible loan programs are identified on the attached appendices. Other loan 
programs may be added to this Commitment from time to time by letter 
agreement between Seller and Purchaser.

SECTION 2. UNDERWRITING GUIDELINES.

Section 2a. DELEGATED UNDERWRITING APPROVAL BY SELLER. Seller shall receive 
delegated underwriting authority, in accordance with the terms and guidelines 
of this Master Commitment. Seller acknowledges and agrees that its 
underwriting will conform to prudent and sound underwriting practices. 
Purchaser may, at its sole option, perform a separate credit evaluation at 
the time the loan is submitted for loan purchase. All loans originated under 
this Master Commitment shall have standard FHLMC or FNMA full or alternative 
documentation and shall generally meet the underwriting guidelines specified 
in the FHLMC SELLER/SERVICER GUIDE and FNMA SELLING AND SERVICING GUIDE, 
unless exceptions to these guidelines are specified in the attached 
appendices or given approval by Purchaser for a specified loan prior to its 
closing.

Section 2b. COMPLIANCE. Seller represents and warrants to Purchaser that any 
and all requirements of federal, state, or local law, rule, or regulation 
applicable to any loan originated under this commitment have been complied 
with, including but not limited to usury, truth-in-lending, real estate 
settlement procedures, consumer credit protection, equal credit opportunity, 
and disclosure laws. Seller shall deliver to Purchaser such evidence of 
compliance with all such requirements that Purchaser may at its sole option

acknowledges and agrees that it is responsible for delivering to borrowers 
all applicable Equal Credit Opportunity Act notices required in connection 
with a loan.

SECTION 3. WEATHER RELATED, TAX AND INSURANCE ESCROWS.

Purchaser shall give Seller the option of waiving escrows for taxes and 
homeowner's insurance if the loan-to-value ratio of the subject loan is less 
than or equal to 80%. Purchaser shall allow weather related escrow holdbacks 
under Seller's current escrow policies. Seller shall not waive escrows for 
flood insurance or private mortgage insurance where such insurance is 
required for any loan.

SECTION 4. PIPELINE OF LOANS.

Seller shall provide to Purchaser at least monthly, but no more frequently 
than weekly, a Pipeline Report of all unfunded loans registered under this 
Master Commitment. At minimum this report shall include lock/float status, 
current interest rate and price, approval status, and projected closing date. 
At request of Purchaser, Seller shall provide separate tracking and reporting

business days of receipt of the Schedule of Loans. Any loan which is not 
eligible for purchase will be suspended and Seller shall have thirty days to 
cure the suspended loan and resubmit it for purchase.

Purchaser shall fund all mortgage loans at its committed price. Pricing shall 
be established by Seller subject to review and approval of Purchaser and 
according to the methodology specified in the attached appendices. All 
funding amounts shall be net of any fees or accrued interest owed to 
Purchaser by Seller.

Section 5b. DELIVERY AND FUNDING DOCUMENTS. At the time of loan delivery, 
Seller's Warehouse Lender shall submit a Schedule of Mortgage Loans to 
Purchaser which shall list all security instruments and mortgage loan 
documents required for funding that are held by Seller or Seller's Warehouse

     CREDIT AGREEMENT, dated as of October 23, 1997, among AMERUS LIFE 
HOLDINGS, INC., an Iowa corporation (the "Borrower"), the lending 
institutions listed from time to time on Annex I hereto (each a "Bank" and, 
collectively, the "Banks"), BANK ONE, INDIANA, NA and ABN AMRO BANK, N.V., 
as Co-Arrangers, and THE CHASE MANHATTAN BANK, as Administrative Agent (the 
"Administrative Agent"). Unless otherwise defined herein, all capitalized 
terms used herein and defined in Section 9 are used herein as so defined.

                             W I T N E S S E T H :

     WHEREAS, subject to and upon the terms and conditions set forth herein, 
the Banks are willing to make available to the Borrower the credit facility 
provided for herein.

     NOW, THEREFORE, IT IS AGREED:

     SECTION 1. AMOUNT AND TERMS OF CREDIT.

     1.01  COMMITMENTS.  Subject to and upon the terms and conditions set 
forth herein, each Bank severally agrees, at any time and from time to time 
on and after the Effective Date and prior to the Maturity Date, to make a 
loan or loans (each, a "Loan" and, collectively, the "Loans") to the 
Borrower, which Loans (i) shall, at the option of the Borrower, be Base Rate 
Loans or Eurodollar Loans, PROVIDED that (x) except as otherwise specifically 
provided in Section 1.10(b), all Loans comprising the same Borrowing shall at 
all times be of the same Type and (y) unless the Administrative Agent has 
determined that the Syndication Date has occurred (at which time this clause 
(y) shall no longer be applicable), prior to the 90th day following the 
Initial Borrowing Date the Borrower may only elect Base Rate Loans, or 
Eurodollar Loans having an Interest Period of one week, and if during such 
period the Borrower elects to have Loans outstanding as Eurodollar Loans, the 
Interest Periods for all such Eurodollar Loans shall begin and end on the 
same dates, (ii) may be repaid and reborrowed at any time in accordance with 
the provisions hereof, (iii) shall have an aggregate principal amount at any 
time outstanding which does not exceed for any Bank the Commitment of such 
Bank at such time and (iv) shall have an aggregate principal amount at any 
time outstanding which does not exceed for all Banks the Total Commitment at 
such time.

<PAGE>

     1.02  MINIMUM AMOUNT OF EACH BORROWING; MAXIMUM NUMBER OF BORROWINGS. The 
aggregate principal amount of each Borrowing hereunder shall not be less than 
$5,000,000 and, if in excess thereof, shall be in an integral multiple of 
$1,000,000.  More than one Borrowing may be incurred on any day; PROVIDED 
that at no time shall there be outstanding more than six Borrowings of 
Eurodollar Loans.

     1.03  NOTICE OF BORROWING.  (a)  In connection with its incurrence of 
Loans on any Business Day, including the Initial Borrowing Date, the Borrower 
shall give the Administrative Agent at its Notice Office, prior to 11:00 A.M. 
(New York time), at least three Business Days' prior written notice (or 
telephonic notice promptly confirmed in writing) of each Eurodollar Loan or 
at least one Business Day's prior written notice (or telephonic notice 
promptly confirmed in writing) of each Base Rate Loan.  Such notice (the 
"Notice of Borrowing"), except as otherwise expressly provided in Section 
1.10, shall be irrevocable, and, in the case of a written notice and a 
confirmation of telephonic notice, shall be in the form of Exhibit A hereto, 
appropriately completed to specify (i) the aggregate principal amount of the 
Loans to be made pursuant to such Borrowing, (ii) the date of such Borrowing 
(which shall be a Business Day) and (iii) whether the respective Borrowings 
shall consist of Base Rate Loans or Eurodollar Loans and, if Eurodollar 
Loans, the Interest Period to be initially applicable thereto.  The 
Administrative Agent shall promptly give each Bank written notice (or 
telephonic notice promptly confirmed in writing) of each proposed Borrowing, 
of such Bank's proportionate share thereof and of the other matters covered 
by the Notice of Borrowing.

     (b)  Without in any way limiting the obligation of the Borrower to 
confirm in writing any notice it may give hereunder by telephone, the 
Administrative Agent may act prior to receipt of written confirmation without 
liability upon the basis of such telephonic notice, believed by the 
Administrative Agent in good faith to be from an Authorized Officer of the 
Borrower.  In each such case the Administrative Agent's record of the terms 
of any such telephonic notice shall be conclusive absent manifest error.

     1.04  DISBURSEMENT OF FUNDS.  (a)  Subject to the terms and conditions 
herein set forth, no later than 11:00 A.M. (New York time) on the date of 
each incurrence of Loans, each Bank will make available to the Administrative 
Agent its PRO RATA share of each Borrowing requested to be made on such date 
in the manner provided below.

     (b)  Each Bank shall make available all amounts it is to fund under any 
Borrowing in U.S. dollars and immediately available funds to the 
Administrative Agent at the Administrative Agent's Payment Office and the 
Administrative Agent will make 

                                     -2-

<PAGE>

available to the Borrower as promptly as practicable by depositing to its 
account at the Administrative Agent's Payment Office the aggregate of the 
amounts so made available in the type of funds received.  Unless the 
Administrative Agent shall have been notified by any Bank prior to the date 
of any such Borrowing that such Bank does not intend to make available to the 
Administrative Agent its portion of the Borrowing or Borrowings to be made on 
such date, the Administrative Agent may assume that such Bank has made such 
amount available to the Administrative Agent on the date of such Borrowing, 
and the Administrative Agent, in reliance upon such assumption, may (in its 
sole discretion and without any obligation to do so) make available to the 
Borrower a corresponding amount.  If such corresponding amount is not in fact 
made available to the Administrative Agent by such Bank and the 
Administrative Agent has made available same to the Borrower, the 
Administrative Agent shall be entitled to recover such corresponding amount 
from such Bank.  If such Bank does not pay such corresponding amount 
forthwith upon the Administrative Agent's demand therefor, the Administrative 
Agent shall promptly notify the Borrower, and the Borrower shall immediately 
pay such corresponding amount to the Administrative Agent.  The 
Administrative Agent shall also be entitled to recover from the Bank or the 
Borrower, as the case may be, interest on such corresponding amount in 
respect of each day from the date such corresponding amount was made 
available by the Administrative Agent to the Borrower to the date such 
corresponding amount is recovered by the Administrative Agent, at a rate per 
annum equal to (x) if paid by such Bank, the overnight Federal Funds 
Effective Rate or (y) if paid by the Borrower, the then applicable rate of 
interest, calculated in accordance with Section 1.08(a) or (b), as the case 
may be, for the respective Loans.

     (c)  Nothing in this Section 1.04 shall be deemed to relieve any Bank 
from its obligation to fulfill its commitments hereunder or to prejudice any 
rights which the Borrower may have against any Bank as a result of any 
default by such Bank hereunder.

     1.05  NOTES.  (a)  The Borrower's obligation to pay the principal of, 
and interest on, all the Loans made to it by each Bank shall be evidenced by 
a promissory note substantially in the form of Exhibit B with blanks 
appropriately completed in conformity herewith (each a "Note" and 
collectively the "Notes").

     (b)  The Note issued to each Bank shall (i) be executed by the Borrower, 
(ii) be payable to the order of such Bank and be dated the Initial Borrowing 
Date (or if issued after the Initial Borrowing Date, be dated the date of the 
issuance thereof), (iii) be in a stated principal amount equal to the 
Commitment of such Bank and be payable in the principal amount of the 
outstanding Loans evidenced thereby, (iv) mature on the Maturity Date, (v) 
bear interest as provided in the appropriate clause of Section 1.08 in 
respect of the Base Rate Loans and Eurodollar Loans, as the case may be, 
evidenced 

                                     -3-

<PAGE>

thereby, (vi) be subject to voluntary prepayment as provided in Section 3.01 
and mandatory repayment as provided in Section 3.02 and (vii) be entitled to 
the benefits of this Agreement and the other Credit Documents.

     (c)  Each Bank will record on its internal records the amount of each 
Loan made by it and each payment in respect thereof and will prior to any 
transfer of its Note endorse on the reverse side thereof the outstanding 
principal amount of Loans evidenced thereby.  Failure to make any such 
notation or any error in any such notation shall not affect the Borrower's 
obligations in respect of such Loans.

     1.06  CONVERSIONS.  The Borrower shall have the option to convert on any 
Business Day all or a portion at least equal to $5,000,000 (and, if in excess 
thereof, an integral multiple of $1,000,000) of the outstanding principal 
amount of the Loans of one Type into a Borrowing or Borrowings of the other 
Type of Loan; PROVIDED that (i) no partial conversion of a Borrowing of 
Eurodollar Loans shall reduce the outstanding principal amount of the 
Eurodollar Loans pursuant to such Borrowing to less than $5,000,000, (ii) 
Base Rate Loans may only be converted into Eurodollar Loans if no Default or 
Event of Default is in existence on the date of the conversion, (iii) 
Borrowings of Eurodollar Loans resulting from this Section 1.06 shall be 
limited in number as provided in Section 1.02, (iv) Eurodollar Loans may only 
be converted into Base Rate Loans on the last day of the Interest Period 
applicable thereto, (v) unless the Administrative Agent has determined that 
the Syndication Date has occurred (at which time this clause (v) shall no 
longer be applicable), prior to the 90th day following the Initial Borrowing 
Date, conversions of Base Rate Loans into Eurodollar Loans may only be made 
in accordance with Section 1.01(i)(y), and (vi) each such conversion shall be 
made PRO RATA among the Loans of each Bank of the Type being converted.  Each 
such conversion shall be effected by the Borrower by giving the 
Administrative Agent at its Notice Office, prior to 11:00 A.M. (New York 
time), at least three Business Days' (or one Business Day's in the case of a 
conversion into Base Rate Loans) prior written notice (or telephonic notice 
promptly confirmed in writing) (each a "Notice of Conversion") specifying the 
Loans to be so converted, the Type of Loans to be converted into and, if to 
be converted into a Borrowing of Eurodollar Loans, the Interest Period to be 
initially applicable thereto.  The Administrative Agent shall give each Bank 
prompt notice of any such proposed conversion affecting any of its Loans.

     1.07  PRO RATA BORROWINGS.  All Borrowings of Loans under this Agreement 
shall be loaned by the Banks PRO RATA on the basis of their Commitments.  It 
is understood that no Bank shall be responsible for any default by any other 
Bank in its obligation to make Loans hereunder and that each Bank shall be 
obligated to make the Loans provided to be made by it hereunder, regardless 
of the failure of any other Bank to fulfill its commitments hereunder.

                                     -4-

     1.08  INTEREST.  (a)  The unpaid principal amount of each Base Rate Loan 
shall bear interest from the date of the Borrowing thereof until the earlier 
of (i) the maturity (whether by acceleration or otherwise) of such Base Rate 
Loan and (ii) the conversion of such Base Rate Loan to a Eurodollar Loan 
pursuant to Section 1.06, at a rate per annum which shall at all times be the 
Base Rate in effect from time to time.

     (b)  The unpaid principal amount of each Eurodollar Loan shall bear 
interest from the date of the Borrowing thereof until the earlier of (i) the 
maturity (whether by acceleration or otherwise) of such Eurodollar Loan or 
(ii) the conversion of such Eurodollar Loan to a Base Rate Loan pursuant to 
Section 1.06, at a rate per annum which shall at all times be the Applicable 
Margin then in effect for Eurodollar Loans plus the relevant Eurodollar Rate 
for the Interest Period applicable to such Eurodollar Loan.

     (c)  Overdue principal and, to the extent permitted by law, overdue 
interest in respect of each Loan and any other overdue amount payable 
hereunder shall bear interest at a rate per annum equal to the Base Rate in 
effect from time to time plus 2%, PROVIDED that overdue principal in respect 
of Eurodollar Loans shall bear interest until the end of the Interest Period 
applicable to such Eurodollar Loans at a rate per annum equal to 2% in excess 
of the rate otherwise applicable to such Eurodollar Loans.

     (d)  Interest shall accrue from and including the date of any Borrowing 
to but excluding the date of any repayment thereof and shall be payable (i) 
in respect of each Base Rate Loan, quarterly in arrears on the last Business 
Day of each calendar quarter, (ii) in respect of each Eurodollar Loan, on the 
last day of each Interest Period applicable thereto and, in the case of an 
Interest Period of six months, on the date occurring three months after the 
first day of such Interest Period and (iii) in respect of each Loan, on any 
conversion or prepayment (on the amount so converted or prepaid), at maturity 
(whether by acceleration or otherwise) and, after such maturity, on demand.

     (e)  All computations of interest hereunder shall be made in accordance 
with Section 11.07(b).

     (f)  The Administrative Agent, upon determining the interest rate for 
any Borrowing of Eurodollar Loans for any Interest Period, shall promptly 
notify the Borrower and the Banks thereof.

     1.09  INTEREST PERIODS.  At the time the Borrower gives a Notice of 
Borrowing or Notice of Conversion in respect of the making of, or conversion 
into, a Borrowing of Eurodollar Loans (in the case of the initial Interest 
Period applicable thereto) or prior to 11:00 A.M. (New York time) on the 
third Business Day prior to 

                                     -5-

<PAGE>

the expiration of an Interest Period applicable to a Borrowing of Eurodollar 
Loans, it shall have the right to elect by giving the Administrative Agent 
written notice (or telephonic notice promptly confirmed in writing) of the 
Interest Period to be applicable to such Borrowing, which Interest Period 
shall, at the option of the Borrower, be a one week period or a one, two, 
three or six month period.  Notwithstanding anything to the contrary 
contained above:

          (i)  the initial Interest Period for any Borrowing of Eurodollar Loans
     shall commence on the date of such Borrowing (including the date of any 
     conversion from a Borrowing of Base Rate Loans) and each Interest Period 
     occurring thereafter in respect of such Borrowing shall commence on the day
     on which the next preceding Interest Period expires;

         (ii)  if any Interest Period begins on a day for which there is no 
     numerically corresponding day in the calendar month at the end of such 
     Interest Period, such Interest Period shall end on the last Business Day of
     such calendar month;

        (iii)  if any Interest Period would otherwise expire on a day which 
     is not a Business Day, such Interest Period shall expire on the next 
     succeeding Business Day, PROVIDED that if any Interest Period would 
     otherwise expire on a day which is not a Business Day but is a day of the
     month after which no further Business Day occurs in such month, such 
     Interest Period shall expire on the next preceding Business Day;

         (iv)  no Interest Period may be elected if it would extend beyond the
     Maturity Date; and

          (v)  no Interest Period may be elected at any time when a Default or
     Event of Default is then in existence.

     If upon the expiration of any Interest Period, the Borrower has failed, 
or is not permitted, to elect a new Interest Period to be applicable to the 
respective Borrowing of Eurodollar Loans as provided above, the Borrower 
shall be deemed to have elected to convert such Borrowing into a Borrowing of 
Base Rate Loans effective as of the expiration date of such current Interest 
Period.

     1.10  INCREASED COSTS, ILLEGALITY, ETC.  (a)  In the event that (x) in
the case of clause (i) below, the Administrative Agent or (y) in the case of
clauses (ii) and (iii) below, any Bank shall have determined in good faith
(which determination shall, absent manifest error, be final and conclusive and
binding upon all parties hereto):

                                     -6-

<PAGE>

          (i)  on any date for determining the Eurodollar Rate for any 
     Interest Period, that, by reason of any changes arising after the Effective
     Date affecting the interbank Eurodollar market, adequate and fair means do 
     not exist for ascertaining the applicable interest rate on the basis 
     provided for in the definition of Eurodollar Rate; or

         (ii)  at any time, that such Bank shall incur increased costs or 
     reductions in the amounts received or receivable hereunder with respect to
     any Eurodollar Loans (other than any increased cost or reduction in the 
     amount received or receivable resulting from the imposition of or a change
     in the rate of taxes or similar charges) because of (x) any change since
     the Effective Date in any applicable law, governmental rule, regulation, 
     guideline, order or request (whether or not having the force of law), or in
     the interpretation or administration thereof and including the introduction
     of any new law or governmental rule, regulation, guideline, order or 
     request (such as, for example, but not limited to, a change in official 
     reserve requirements, but, in all events, excluding reserves required under
     Regulation D to the extent included in the computation of the Eurodollar 
     Rate) and/or (y) other circumstances affecting the interbank Eurodollar 
     market or the position of such Bank in such market; or

        (iii)  at any time, that the making or continuance of any Eurodollar 
     Loan has become unlawful by compliance by such Bank in good faith with any 
     change since the Effective Date in any law, governmental rule, regulation, 
     guideline or order, or the interpretation or application thereof, or would 
     conflict with any thereof not having the force of law but with which such 
     Bank customarily complies, or has become impracticable as a result of a 
     contingency occurring after the Effective Date which materially adversely 
     affects the interbank Eurodollar market;

then, and in any such event, such Bank (or the Administrative Agent in the 
case of clause (i) above) shall (x) on such date and (y) within 10 Business 
Days of the date on which such event no longer exists give notice (by 
telephone confirmed in writing) to the Borrower and to the Administrative 
Agent of such determination and the reason therefor (which notice the 
Administrative Agent shall promptly transmit to each of the other Banks).  
Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no 
longer be available until such time as the Administrative Agent notifies the 
Borrower and the Banks that the circumstances giving rise to such notice by 
the Administrative Agent no longer exist, and any Notice of Borrowing or 
Notice of Conversion given by the Borrower with respect to Eurodollar Loans 
which have not yet been incurred shall be deemed rescinded by the Borrower 
or, in the case of a Notice of Borrowing, shall, at the option of the 
Borrower, be deemed converted into a Notice of Borrowing for 

                                     -7-

<PAGE>

Base Rate Loans to be made on the date of Borrowing contained in such Notice 
of Borrowing, (y) in the case of clause (ii) above, the Borrower shall pay to 
such Bank, upon written demand therefor, such additional amounts (in the form 
of an increased rate of, or a different method of calculating, interest or 
otherwise as such Bank shall determine in good faith) as shall be required to 
compensate such Bank for such increased costs or reductions in amounts 
receivable hereunder (a written notice as to the additional amounts owed to 
such Bank, showing the basis for the calculation thereof, which basis shall 
be reasonable and consistently applied, submitted to the Borrower by such 
Bank shall, absent manifest error, be final and conclusive and binding upon 
all parties hereto) and (z) in the case of clause (iii) above, the Borrower 
shall take one of the actions specified in Section 1.10(b) as promptly as 
possible and, in any event, within the time period required by law.

     (b) At any time that any Eurodollar Loan is affected by the 
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may 
(and in the case of a Eurodollar Loan affected pursuant to Section 
1.10(a)(iii) the Borrower shall) either (i) if the affected Eurodollar Loan 
is then being made pursuant to a Borrowing, by giving the Administrative 
Agent telephonic notice (confirmed promptly in writing) thereof on the same 
date that the Borrower was notified by a Bank (or on the next Business Day if 
the Borrower received such notice after 3:00 p.m. (New York time)) pursuant 
to Section 1.10(a)(ii) or (iii), cancel said Borrowing, convert the related 
Notice of Borrowing into one requesting a Borrowing of Base Rate Loans or 
require the affected Bank to make its requested Loan as a Base Rate Loan, or 
(ii) if the affected Eurodollar Loan is then outstanding, upon at least one 
Business Day's notice to the Administrative Agent, require the affected Bank 
to convert each such affected Eurodollar Loan into a Base Rate Loan, PROVIDED 
that if more than one Bank is affected at any time, then all affected Banks 
must be treated the same pursuant to this Section 1.10(b).

     (c) If any Bank shall have determined in good faith that after the 
Effective Date the adoption or effectiveness of any applicable law, rule or 
regulation regarding capital adequacy, or any change therein, or any change 
in the interpretation or administration thereof by any governmental 
authority, central bank or comparable agency charged by law with the 
interpretation or administration thereof, or compliance by such Bank or its 
parent corporation with any request or directive regarding capital adequacy 
(whether or not having the force of law) of any such authority, central bank 
or comparable agency, in each case made subsequent to the Effective Date, has 
or would have the effect of reducing the rate of return on such Bank's or its 
parent corporation's capital or assets as a consequence of such Bank's 
commitments or obligations hereunder to a level below that which such Bank or 
its parent corporation could have achieved but for such adoption, 
effectiveness, change or compliance (taking into consideration such Bank's or 
its parent corporation's policies with respect to capital 

                                     -8-

<PAGE>

adequacy), then from time to time, upon demand by such Bank (with a copy to 
the Administrative Agent), the Borrower shall pay to such Bank such 
additional amount or amounts as will compensate such Bank or its parent 
corporation for such reduction.  Each Bank, upon determining in good faith 
that any additional amounts will be payable pursuant to this Section 1.10(c), 
will give prompt written notice thereof to the Borrower, which notice shall 
set forth the basis of the calculation of such additional amounts, which 
basis must be reasonable and consistently applied, although the failure to 
give any such notice shall not release or diminish any of the Borrower's 
obligations to pay additional amounts pursuant to this Section 1.10(c) upon 
the subsequent receipt of such notice.

     1.11  COMPENSATION.  The Borrower shall compensate each Bank, upon its 
written request (which request shall set forth the basis for requesting such 
compensation), for all reasonable losses, expenses and liabilities 
(including, without limitation, any loss, expense or liability incurred by 
reason of the liquidation or reemployment of deposits or other funds required 
by such Bank to fund its Eurodollar Loans but excluding any loss of 
anticipated profit with respect to such Loans) which such Bank may sustain:  
(i) if for any reason (other than a default by such Bank or the 
Administrative Agent) a Borrowing of Eurodollar Loans does not occur on a 
date specified therefor in a Notice of Borrowing or Notice of Conversion 
(whether or not withdrawn by the Borrower or deemed withdrawn pursuant to 
Section 1.10(a)); (ii) if any repayment, prepayment or conversion of any of 
its Eurodollar Loans occurs on a date which is not the last day of an 
Interest Period applicable thereto; (iii) if any prepayment of any of its 
Eurodollar Loans is not made on any date specified in a notice of prepayment 
given by the Borrower; or (iv) as a consequence of (x) any other failure by 
the Borrower to repay its Loans when required by the terms of this Agreement 
or (y) an election made pursuant to Section 1.10(b).  Calculation of all 
amounts payable to a Bank under this Section 1.11 shall be made as though 
that Bank had actually funded its relevant Eurodollar Loan through the 
purchase of a Eurodollar deposit bearing interest at the Eurodollar Rate in 
an amount equal to the amount of that Loan, having a maturity comparable to 
the relevant Interest Period and through the transfer of such Eurodollar 
deposit from an offshore office of that Bank or other bank to a domestic 
office of that Bank in the United States of America; PROVIDED, HOWEVER, that 
each Bank may fund each of its Eurodollar Loans in any manner it sees fit and 
the foregoing assumption shall be utilized only for the calculation of 
amounts payable under this Section 1.11.

     1.12  CHANGE OF LENDING OFFICE.  Each Bank agrees that, upon the 
occurrence of any event giving rise to the operation of Section 1.10(a)(ii) 
or (iii) or 3.04 with respect to such Bank, it will, if requested by the 
Borrower, use reasonable efforts (subject to overall policy considerations of 
such Bank) to designate another lending office for any Loans affected by such 
event; PROVIDED that such designation is made on such 

                                     -9-

<PAGE>

terms that, in the opinion of such Bank, such Bank and its lending office 
suffer no economic, legal or regulatory disadvantage, with the object of 
avoiding the consequence of the event giving rise to the operation of any 
such Section.  Nothing in this Section 1.12 shall affect or postpone any of 
the obligations of the Borrower or the right of any Bank provided in Section 
1.10 or 3.04.

     SECTION 2.  FEES; COMMITMENTS.

     2.01  FEES. (a)  The Borrower agrees to pay the Administrative Agent a 
commitment fee (the "Commitment Fee") for the account of each Bank for the 
period from and including the Effective Date to but excluding the earlier of 
the Maturity Date and the date the Total Commitment has been terminated (the 
"Termination Date"), computed at a per annum rate equal to the Applicable 
Commitment Fee Percentage from time to time on the daily average Unutilized 
Commitment of such Bank.  Accrued Commitment Fees shall be due and payable in 
arrears on the last Business Day of each March, June, September and December 
and on the Termination Date.

     (b) The Borrower agrees to pay the Administrative Agent a utilization 
fee (the "Utilization Fee") for the account of each Bank for each day from 
and including the Effective Date to and including the earlier of the Maturity 
Date and the Termination Date on which the outstanding principal amount of 
all Loans made by such Bank equals or exceeds 50% of the Commitment of such 
Bank, computed at a per annum rate equal to the Applicable Utilization Fee 
Percentage from time to time on the outstanding principal amount of Loans of 
such Bank from time to time.  Accrued Utilization Fees shall be due and 
payable in arrears on the last Business Day of each March, June, September 
and December and on the Termination Date.

     (c) The Borrower shall pay to the Administrative Agent, for the account 
of the Administrative Agent, when and as due, such fees as have been, or are 
from time to time, separately agreed upon.

     (d) All computations of Fees shall be made in accordance with Section 
11.07(b).

     2.02  VOLUNTARY REDUCTION OF COMMITMENTS.  Upon at least three Business 
Days' prior written notice (or telephonic notice promptly confirmed in 
writing) given by the Borrower to the Administrative Agent at its Notice 
Office (which notice the Administrative Agent shall promptly transmit to each 
of the Banks), the Borrower shall have the right, without premium or penalty, 
to terminate, in whole or in part, the Total Unutilized Commitment, PROVIDED 
that (x) partial reductions of the Total


                                      -10-
<PAGE>

Unutilized Commitment pursuant to this Section 2.02 shall be in the amount of 
at least $5,000,000, and (y) any such termination shall apply proportionately 
to permanently reduce the Commitment of each of the Banks.

          2.03 MANDATORY REDUCTION OF COMMITMENTS.  (a) The Total Commitment 
(and the Commitment of each Bank) shall be terminated at 5:00 p.m. (New York 
time) on the Expiration Date unless the Effective Date has occurred on or 
before such date.

          (b)  The Total Commitment shall terminate on the Maturity Date.

          (c)  In addition to any other mandatory commitment reductions 
pursuant to this Section 2.03, the Total Commitment shall be permanently 
reduced on any date after the Effective Date on which the Borrower incurs any 
Indebtedness for borrowed money (other than Indebtedness for borrowed money 
incurred pursuant to Sections 7.04(a)-(o)) by an amount equal to 50% of the 
net proceeds of such Indebtedness.  Any reduction to the Total Commitment 
pursuant to this Section 2.03(c) shall be applied proportionately to reduce 
the Commitment of each Bank; PROVIDED, that in no event shall the Total 
Commitment be reduced below $150,000,000 at any time as a result of this 
Section 2.03(c).

          SECTION 3.  PAYMENTS.

          3.01 VOLUNTARY PREPAYMENTS.  The Borrower shall have the right to 
prepay Loans, without premium or penalty (except for amounts payable pursuant 
to Section 1.11), in whole or in part, from time to time on the following 
terms and conditions: (i) the Borrower shall give the Administrative Agent at 
its Notice Office written notice (or telephonic notice promptly confirmed in 
writing) of its intent to prepay the Loans, the amount of such prepayment and 
(in the case of Eurodollar Loans) the specific Borrowing(s) pursuant to which 
made, which notice shall be received by the Administrative Agent (x) in the 
case of Base Rate Loans, no later than 11:00 A.M. (New York time) one 
Business Day prior to the date of such prepayment, or (y) in the case of 
Eurodollar Loans, three Business Days prior to the date of such prepayment, 
which notice shall promptly be transmitted by the Administrative Agent to 
each of the Banks; (ii) each partial prepayment of any Borrowing shall be in 
an aggregate principal amount of at least $5,000,000, PROVIDED that no 
partial prepayment of Eurodollar Loans made pursuant to a Borrowing shall 
reduce the aggregate principal amount of the Loans outstanding pursuant to 
such Borrowing to an amount less than $5,000,000; and (iii) each prepayment 
in respect of any Loans made pursuant to a Borrowing shall be applied PRO 
RATA among such Loans.


                                      -11-

<PAGE>

          3.02 MANDATORY REPAYMENTS.  (a) On any day on which the sum of the 
aggregate outstanding principal amount of the Loans exceeds the Total 
Commitment as then in effect, the Borrower shall prepay principal of Loans in 
an amount equal to such excess.

          (b)  With respect to each repayment of Loans required by this 
Section 3.02, the Borrower may designate the Types of Loans which are to be 
repaid and, in the case of Eurodollar Loans, the specific Borrowing or 
Borrowings pursuant to which made, PROVIDED that:  (i) if any repayment of 
Eurodollar Loans made pursuant to a single Borrowing shall reduce the 
outstanding Eurodollar Loans made pursuant to such Borrowing to an amount 
less than $5,000,000 such Borrowing shall be converted immediately into a 
Borrowing of Base Rate Loans and (ii) each repayment of Loans made pursuant 
to the same Borrowing shall be applied PRO RATA among the Banks which made 
such Loans.  In the absence of a designation by the Borrower as described in 
the preceding sentence, the Administrative Agent shall, subject to the above, 
make such designation in its sole discretion.

          3.03 METHOD AND PLACE OF PAYMENT.  Except as otherwise specifically 
provided herein, all payments under this Agreement and the Notes shall be 
made to the Administrative Agent for the ratable account of the Banks 
entitled thereto, not later than 11:00 A.M. (New York time) on the date when 
due and shall be made in immediately available funds and in lawful money of 
the United States of America at the Payment Office, it being understood that 
written, telex or facsimile notice by the Borrower to the Administrative 
Agent to make a payment from the funds in the Borrower's account at the 
Payment Office shall constitute the making of such payment to the extent of 
such funds held in such account.  Any payments under this Agreement which are 
made later than 11:00 A.M. (New York time) shall be deemed to have been made 
on the next succeeding Business Day.  Whenever any payment to be made 
hereunder shall be stated to be due on a day which is not a Business Day, the 
due date thereof shall be extended to the next succeeding Business Day and, 
with respect to payments of principal, interest shall be payable during such 
extension at the applicable rate in effect immediately prior to such 
extension.

          3.04 NET PAYMENTS.  (a) All payments made by the Borrower hereunder 
or under any Note will be made without setoff, counterclaim or other defense. 
Except as provided in Section 3.04(b), all such payments will be made free 
and clear of, and without deduction or withholding for, any present or future 
taxes, levies, imposts, duties, fees, assessments or other charges of 
whatever nature now or hereafter imposed by any jurisdiction or by any 
political subdivision or taxing authority thereof or therein with respect to 
such payments (but excluding, except as provided in the second succeeding 
sentence, any tax imposed on or measured by the net income or net profits of 
a 


                                      -12-

<PAGE>

Bank, or franchise taxes imposed on it, pursuant to the laws of the 
jurisdiction in which it is organized or the jurisdiction in which the 
principal office or applicable lending office of such Bank is located or any 
subdivision thereof or therein) and all interest, penalties or similar 
liabilities with respect to such non-excluded taxes, levies, imposts, duties, 
fees, assessments or other charges (all such non-excluded taxes, levies, 
imposts, duties, fees, assessments or other charges being referred to 
collectively as "Taxes").  If any Taxes are so levied or imposed, the 
Borrower agrees to pay the full amount of such Taxes, and such additional 
amounts as may be necessary so that every payment of all amounts due under 
this Agreement or under any Note, after withholding or deduction for or on 
account of any Taxes, will not be less than the amount provided for herein or 
in such Note.  If any amounts are payable in respect of Taxes pursuant to the 
preceding sentence, the Borrower agrees to reimburse each Bank, upon the 
written request of such Bank, for taxes imposed on or measured by the net 
income or net profits of such Bank, and franchise taxes imposed on such Bank, 
pursuant to the laws of the jurisdiction in which such Bank is organized or 
in which the principal office or applicable lending office of such Bank is 
located or under the laws of any political subdivision or taxing authority of 
any such jurisdiction in which such Bank is organized or in which the 
principal office or applicable lending office of such Bank is located and for 
any withholding of taxes as such Bank shall determine are payable by, or 
withheld from, such Bank, in respect of such amounts so paid to or on behalf 
of such Bank pursuant to the preceding sentence and in respect of any amounts 
paid to or on behalf of such Bank pursuant to this sentence.  The Borrower 
will furnish to the Administrative Agent within 45 days after the date the 
payment of any Taxes is due pursuant to applicable law certified copies of 
tax receipts evidencing such payment by the Borrower.  The Borrower agrees to 
indemnify and hold harmless each Bank, and reimburse such Bank upon its 
written request, for the amount of any Taxes so levied or imposed and paid by 
such Bank.

          (b)  Each Bank that is not a United States person (as such term is 
defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax 
purposes agrees to deliver to the Borrower and the Administrative Agent on or 
prior to the Effective Date, or in the case of a Bank that is an assignee or 
transferee of an interest under this Agreement pursuant to Section 11.04(b) 
(unless the respective Bank was already a Bank hereunder immediately prior to 
such assignment or transfer), on the date of such assignment or transfer to 
such Bank, (i) two accurate and complete original signed copies of Internal 
Revenue Service Form 4224 or 1001 (or successor forms) certifying to such 
Bank's entitlement to a complete exemption from United States withholding tax 
with respect to payments to be made under this Agreement and under any Note, 
or (ii) if the Bank is not a "bank" within the meaning of Section 
881(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service 
Form 1001 or 4224 pursuant to clause (i) above, (x) a certificate 
substantially in the form of Exhibit C (any such certificate, 


                                      -13-

<PAGE>

a "Section 3.04(b)(ii) Certificate") and (y) two accurate and complete 
original signed copies of Internal Revenue Service Form W-8 (or successor 
form) certifying to such Bank's entitlement to a complete exemption from 
United States withholding tax with respect to payments of interest to be made 
under this Agreement and under any Note.  In addition, each Bank agrees that 
from time to time after the Effective Date, when a lapse in time or change in 
circumstances renders the previous certification obsolete or inaccurate in 
any material respect, it will deliver to the Borrower and the Administrative 
Agent two new accurate and complete original signed copies of Internal 
Revenue Service Form 4224 or 1001, or Form W-8 and a Section 3.04(b)(ii) 
Certificate, as the case may be, and such other forms as may be required in 
order to confirm or establish the entitlement of such Bank to a continued 
exemption from or reduction in United States withholding tax with respect to 
payments under this Agreement and any Note, or it shall immediately notify 
the Borrower and the Administrative Agent of its inability to deliver any 
such Form or Certificate, in which case such Bank shall not be required to 
deliver any such Form or Certificate pursuant to this Section 3.04(b). 
Notwithstanding anything to the contrary contained in Section 3.04(a), but 
subject to Section 11.04(b) and the immediately succeeding sentence, (x) the 
Borrower shall be entitled, to the extent it is required to do so by law, to 
deduct or withhold income or similar taxes imposed by the United States (or 
any political subdivision or taxing authority thereof or therein) from 
interest, Fees or other amounts payable hereunder for the account of any Bank 
which is not a United States person (as such term is defined in Section 
7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent 
that such Bank has not provided to the Borrower U.S. Internal Revenue Service 
Forms that establish a complete exemption from such deduction or withholding 
and (y) the Borrower shall not be obligated pursuant to Section 3.04(a) 
hereof to gross-up payments to be made to a Bank in respect of income or 
similar taxes imposed by the United States if (I) such Bank has not provided 
to the Borrower the Internal Revenue Service Forms required to be provided to 
the Borrower pursuant to this Section 3.04(b) or (II) in the case of a 
payment, other than interest, to a Bank described in clause (ii) above, to 
the extent that such Forms do not establish a complete exemption from 
withholding of such taxes.  Notwithstanding anything to the contrary 
contained in the preceding sentence or elsewhere in this Section 3.04 and 
except as set forth in Section 11.04(b), the Borrower agrees to pay any 
additional amounts and to indemnify each Bank in the manner set forth in 
Section 3.04(a) (without regard to the identity of the jurisdiction requiring 
the deduction or withholding) in respect of any Taxes deducted or withheld by 
it as described in the immediately preceding sentence as a result of any 
changes after the Effective Date in any applicable law, treaty, governmental 
rule, regulation, guideline or order, or in the interpretation thereof, 
relating to the deducting or withholding of such Taxes.

          (b)  NOTICE OF BORROWING.  Prior to the making of each Loan, the 
     Administrative Agent shall have received a Notice of Borrowing meeting 
     the requirements of Section 1.03(a).

          The occurrence of the Initial Borrowing Date and the acceptance of 
the proceeds of each Loan shall constitute a representation and warranty by 
the Borrower to the Administrative Agent and each of the Banks that all the 
conditions specified in this Section 4 and applicable to the Initial 
Borrowing Date and/or the making of such Loan, as the case may be, exist as 
of that time (except to the extent that any of the conditions specified in 
this Section 4 are required to be satisfactory to or determined by any Bank, 
the Required Banks and/or the Administrative Agent or otherwise expressly 
calls for a subjective determination to be made by any Bank, the Required 
Banks and/or the Administrative Agent).  All of the Notes, certificates, 
legal opinions and other documents and papers referred to in this Section 4, 
unless otherwise specified, shall be delivered to the Administrative Agent at

to induce the Banks to enter into this Agreement and to make the Loans 
provided for herein, the Borrower makes the following representations and 
warranties to, and agreements with, the Banks, all of which shall survive the 
execution and delivery of this Agreement and the making of the Loans (with 
the making of each Loan being deemed to constitute a representation and 
warranty that the matters specified in this Section 5 are true and correct in 
all material respects on and as of the date of the making of such Loan unless 
such representation and warranty expressly indicates that it is being made as 
of any specific date in which case such representation and warranty shall be 
true and correct in all material respects as of such specified date):

          5.01 CORPORATE STATUS.  Except as disclosed on Annex III hereto,

other organizational power and authority to own its property and assets and 
to transact the business in which it is engaged and presently proposes to 
engage, and (ii) has been duly qualified and is authorized to do business and 
is in good standing in all jurisdictions where it is required to be so

power and authority to execute, deliver and carry out the terms and 
provisions of the Credit Documents to which it is a party and has taken all 
necessary corporate action to authorize the execution, delivery and 
performance of the Credit Documents to which it is a party.  The Borrower has 
duly executed and delivered each Credit Document to which it is a party and 
each such Credit Document constitutes the legal, valid and binding obligation 
of the Borrower enforceable against the Borrower in accordance with its 
terms, except to the extent that enforceability thereof may be limited by 
applicable bankruptcy, insolvency, moratorium or similar laws affecting 
creditors' rights generally and general principles of equity regardless of 
whether enforcement is sought in a proceeding in equity or at law.

          5.03 NO CONTRAVENTION OF LAWS, AGREEMENTS OR ORGANIZATIONAL 
DOCUMENTS. Neither the execution, delivery and performance by the Borrower of 
the Credit Documents to which it is a party nor compliance with the terms and 
provisions thereof, nor the consummation of the transactions contemplated 
therein, (i) will contravene any applicable provision of any law, statute, 
rule, regulation, order, writ, injunction or decree of any court or 
governmental instrumentality, (ii) will conflict or be inconsistent with or 
result in any breach of any of the terms, covenants, conditions or provisions 
of, or constitute a default under, or (other than pursuant to the Pledge 
Agreement) result in the creation or imposition of (or the obligation to 
create or impose) any Lien upon any of the property or assets of the Borrower 
or any of its Subsidiaries pursuant to the terms of, any indenture, mortgage, 
deed of trust, loan agreement, credit agreement or any other material 
instrument to which the Borrower or any of its Subsidiaries is a party or by 
which it or any of its property or assets are bound or to which it may be 
subject or (iii) will violate any provision of the Certificate of 
Incorporation or By-Laws of the Borrower or any of its Subsidiaries.

          5.04 LITIGATION AND CONTINGENT LIABILITIES.  There are no actions,

or any of its Subsidiaries (including, without limitation, with respect to 
this Agreement or any documentation executed in connection herewith) (i) that 
have or could reasonably be expected to have a Material Adverse Effect or 
(ii) that could reasonably be expected to have a material adverse effect on 
the rights or remedies of the Banks, the Administrative Agent or the 
Collateral Agent or on the ability of the Borrower to perform its respective 
obligations to the Banks, the Administrative Agent or the Collateral Agent 
hereunder and under the other Credit Documents to which it is, or will be, a 
party.

  Agreement and all fees, interest and other amounts payable thereunder in
  their entirety; and

     (ii) second, to finance the Delta Life Acquisition.

     (b)  After compliance with clause (a) above, the proceeds of the Loans 
incurred on the Initial Borrowing Date and thereafter shall be utilized as

hereunder; and (ii) for general corporate purposes.

     (c)  Neither the making of any Loan hereunder or other Indebtedness or 
financing of the Borrower, nor the use of the proceeds thereof, will violate 
or be inconsistent with the provisions of Regulation G, T, U or X of the 
Board of Governors of the Federal Reserve System and no part of the proceeds 
of any Loan or other Indebtedness or financing of the Borrower will be used 
to purchase or carry any Margin Stock or to extend credit for the purpose of 
purchasing or carrying any Margin Stock.

     5.06  APPROVALS.  Any order, consent, approval, license, authorization, 
or validation of, or filing, recording or registration with, or exemption by, 
any foreign or domestic governmental or public body or authority, or any

connection with (i) the execution, delivery and performance of any Credit 
Document or (ii) the legality, validity, binding effect or enforceability of 
any Credit Document, has been obtained.

Public Utility Holding Company Act of 1935, as amended.

     5.09  TRUE AND COMPLETE DISCLOSURE; PROJECTIONS AND ASSUMPTIONS.  All 
factual information (taken as a whole) heretofore or contemporaneously 
furnished by or on behalf of the Borrower or any of its Subsidiaries to the 
Administrative Agent or any Bank (including, without limitation, all 
information contained in the Credit Documents) for purposes of or in 
connection with this Agreement or any transaction contemplated herein is, and 
all other factual information (taken as a whole) hereafter


                                      -21-

<PAGE>

furnished by or on behalf of any such Persons in writing to the 
Administrative Agent will be, true and accurate in all material respects on 
the date as of which such information is dated and not incomplete by omitting 
to state any material fact necessary to make such information (taken as a 
whole) not misleading at such time in light of the circumstances under which 
such information was provided.  The projections contained in such materials 
are based on good faith estimates and assumptions believed by the Borrower to 
be reasonable and attainable at the time made, it being recognized by the 
Banks that such projections as to future events are not to be viewed as facts 
and that actual results during the period or periods covered by any such 
projections may differ from the projected results.

     5.10  FINANCIAL CONDITION; FINANCIAL STATEMENTS.  (a)  The financial 
statements delivered to the Administrative Agent pursuant to Section 4.01(i)

extent provided in the notes to said financial statements.

a whole, has or is reasonably likely to have a Material Adverse Effect.

      5.11  SECURITY INTERESTS.  On and after the Initial Borrowing Date but 
prior to the Collateral Release Date, the Pledge Agreement creates, as 
security for the Obligations, valid and enforceable perfected security 
interests in and Liens on all of the Collateral subject thereto, superior to 
and prior to the rights of all third persons, and subject to no other Liens, 
in favor of the Collateral Agent for the benefit of the Banks.  At all times 
on or after the Initial Borrowing Date but prior to the Collateral Release 
Date, the Borrower has good and marketable title to all Collateral free and 
clear of all Liens (except as created pursuant to the Pledge Agreement).  No 
filings or recordings are required in order to perfect the security interests 
created under the Pledge Agreement.

     5.12  TAX RETURNS AND PAYMENTS.  The Borrower and its Subsidiaries have 
filed or have obtained valid extensions with respect to all material income 
and other material tax returns which are required to be filed and have paid,

said returns or on any assessments made against them or their property and 
all other material taxes, assessments, fees or other charges imposed on them

there are no waivers or agreements for the extension of time for the 
assessment of any tax other than those not reasonably likely to have a 
Material Adverse Effect.  No tax Liens have been filed and no claims are

with respect to any such taxes, fees or other charges for any fiscal period, 
which are reasonably likely to have a Material Adverse Effect.

     5.13  COMPLIANCE WITH ERISA.  (a)  Annex IV sets forth each Plan in 
effect on the Effective Date; each Plan (and each related trust, insurance 
contract or fund) is in compliance with its terms and with all applicable 
laws, including without limitation ERISA and the Code; each Plan (and each 
related trust, if any) which is intended to be qualified under Section 401(a) 
of the Code has received a determination letter from the Internal Revenue

501(a) of the Code and/or, in the case of a Plan amendment, has timely filed

Affiliate; neither the Borrower nor any Subsidiary of the Borrower nor any 
ERISA Affiliate has incurred any liability (including any indirect, 
contingent or secondary liability) to or on account of a Plan pursuant to 
Section 409, 502(i), 502(1), 515, 4062, 4063, 4064, 4069, 4201, 4204, or 4212

of the Code; no lien imposed under the Code or ERISA on the assets of the

Subsidiaries may cease contributions to or terminate any employee benefit 
plan maintained by any of them without incurring any liability; PROVIDED that

compliance with all applicable environmental laws), except such failure(s) to 
comply as would not, in the aggregate, have a Material Adverse Effect.  All 
required regulatory approvals are in full force and effect on the date 
hereof, except where the failure of such approvals to be in full force and 
effect could not, individually or in the aggregate, reasonably be expected to 
have a Material Adverse Effect.

where issued or have been filed with and not objected to by such authorities 
within the period provided for objection, except for those forms with respect 
to which a failure to obtain such approval or make such a filing without it 
being objected to, could not, singly or in the aggregate, reasonably be 
expected to have a Material Adverse Effect.

described in Annex X are the only material contracts regarding reinsurance, 
coinsurance, excess insurance, ceding of insurance (other than insurance

<PAGE>

Agreement and the other Credit Documents and to exercise such powers and 
perform such duties as are expressly delegated to the Administrative Agent by 
the terms of this Agreement and the other Credit Documents, together with 
such other powers as are reasonably incidental thereto. The Administrative 
Agent agrees to act as such upon the express conditions contained in this 
Section 10.  Notwithstanding any provision to the contrary elsewhere in this 
Agreement, the Administrative Agent shall not have any duties or 
responsibilities, except those expressly set forth herein or in the other 
Credit Documents, nor any fiduciary relationship with any Bank, and no 
implied covenants, functions, responsibilities, duties, obligations or 
liabilities shall be read into this Agreement or otherwise exist against the 
Administrative Agent. The provisions of this Section 10 are solely for the 
benefit of the Administrative Agent and the Banks, and the Borrower shall not 
have any rights as a third party beneficiary of any of the provisions hereof. 
 In performing its functions and duties under this Agreement, the 
Administrative Agent shall act solely as agent of the Banks and does not 
assume and shall not be deemed to have assumed any obligation or relationship 
of agency or trust with or for the Borrower.

         10.2  DELEGATION OF DUTIES.  The Administrative Agent may execute 
any of its duties under this Agreement or any other Credit Document by or 
through agents or attorneys-in-fact and shall be entitled to advice of 
counsel concerning all matters pertaining to such duties.  The Administrative 
Agent shall not be responsible for the negligence or misconduct of any agents 
or attorneys-in-fact selected by it with reasonable care except to the extent 
otherwise required by Section 10.03.

         10.3  EXCULPATORY PROVISIONS.  Neither the Administrative Agent nor 
any of its officers, directors, employees, agents, attorneys-in-fact or 
affiliates shall be (i) liable for any action lawfully taken or omitted to be 
taken by it or such Person under or in connection with this Agreement (except 
for its or such Person's own gross negligence or willful misconduct) or (ii) 
responsible in any manner to any of the Banks for any recitals, statements, 
representations or warranties made by the Borrower or any Subsidiary or any 
of their respective officers contained in this Agreement, any other Credit 
Document or in any certificate, report, statement or other document referred 
to or provided for in, or received by the Administrative Agent under or in 
connection with, this Agreement or any other Credit Document or for any 
failure of the Borrower or any of its Subsidiaries or any of their respective 
officers to perform its obligations hereunder or thereunder.  The 
Administrative Agent shall not be under any obligation to any Bank to 
ascertain or to inquire as to the observance or performance of any of the 
agreements contained in, or conditions of, this Agreement, or to inspect the 
properties, books or records of the Borrower or any of its Subsidiaries.  The 
Administrative Agent shall not be responsible to any Bank for the 
effectiveness, genuineness, validity, enforceability, collectibility or 
sufficiency of this Agreement or any Credit Document

                                       -68-

<PAGE>

or for any representations, warranties, recitals or statements made herein or 
therein or made in any written or oral statement or in any financial or other 
statements, instruments, reports, certificates or any other documents in 
connection herewith or therewith furnished or made by the Administrative 
Agent to the Banks or by or on behalf of the Borrower to the Administrative 
Agent or any Bank or be required to ascertain or inquire as to the 
performance or observance of any of the terms, conditions, provisions, 
covenants or agreements contained herein or therein or as to the use of the 
proceeds of the Loans or of the existence or possible existence of any 
Default or Event of Default.

         10.4  RELIANCE BY ADMINISTRATIVE AGENT.  The Administrative Agent 
shall be entitled to rely, and shall be fully protected in relying, upon any 
note, writing, resolution, notice, consent, certificate, affidavit, letter, 
cablegram, telegram, facsimile transmission, telex or teletype message, 
statement, order or other document or conversation believed by it to be 
genuine and correct and to have been signed, sent or made by the proper 
Person or Persons and upon advice and statements of legal counsel (including, 
without limitation, counsel to the Borrower), independent accountants and 
other experts selected by the Administrative Agent.  The Administrative Agent 
shall be fully justified in failing or refusing to take any action under this 
Agreement or any other Credit Document unless it shall first receive such 
advice or concurrence of the Required Banks as it deems appropriate or it 
shall first be indemnified to its satisfaction by the Banks against any and 
all liability and expense which may be incurred by it by reason of taking or 
continuing to take any such action. The Administrative Agent shall in all 
cases be fully protected in acting, or in refraining from acting, under this 
Agreement and the other Credit Documents in accordance with a request of the 
Required Banks, and such request and any action taken or failure to act 
pursuant thereto shall be binding upon all the Banks.

         10.5  NOTICE OF DEFAULT.  The Administrative Agent shall not be 
deemed to have knowledge or notice of the occurrence of any Default or Event 
of Default hereunder unless the Administrative Agent has received notice from 
a Bank or the Borrower referring to this Agreement, describing such Default 
or Event of Default and stating that such notice is a "notice of default."  
In the event that the Administrative Agent receives such a notice, the 
Administrative Agent shall give prompt notice thereof to the Banks.  The 
Administrative Agent shall take such action with respect to such Default or 
Event of Default as shall be reasonably directed by the Required Banks, 
PROVIDED that unless and until the Administrative Agent shall have received 
such directions, the Administrative Agent may (but shall not be obligated to) 
take such action, or refrain from taking such action, with respect to such 
Default or Event of Default as it shall deem advisable in the best interests 
of the Banks.

                                       -69-
<PAGE>

     10.06  NON-RELIANCE.  Each Bank expressly acknowledges that neither the 
Administrative Agent nor any of its officers, directors, employees, agents, 
attorneys-in-fact or affiliates have made any representations or warranties 
to it and that no act by the Administrative Agent hereinafter taken, 
including any review of the affairs of the Borrower or any of its 
Subsidiaries, shall be deemed to constitute any representation or warranty by 
the Administrative Agent to any Bank.  Each Bank represents to the 
Administrative Agent that it has, independently and without reliance upon the 
Administrative Agent or any other Bank, and based on such documents and 
information as it has deemed appropriate, made its own appraisal of and 
investigation into the business, assets, operations, property, financial and 
other conditions, prospects and creditworthiness of the Borrower and its 
Subsidiaries and made its own decision to make its Loans hereunder and enter 
into this Agreement.  Each Bank also represents that it will, independently 
and without reliance upon the Administrative Agent or any other Bank, and 
based on such documents and information as it shall deem appropriate at the 
time, continue to make its own credit analysis, appraisals and decisions in 
taking or not taking action under this Agreement, and to make such 
investigation as it deems necessary to inform itself as to the business, 
assets, operations, property, financial and other conditions, prospects and 
creditworthiness of the Borrower and its Subsidiaries. The Administrative 
Agent shall not have any duty or responsibility to provide any Bank with any 
credit or other information concerning the business, operations, assets, 
property, financial and other conditions, prospects or creditworthiness of 
the Borrower or any Subsidiary which may come into the possession of the 
Administrative Agent or any of its officers, directors, employees, agents, 
attorneys-in-fact or affiliates.

     10.07  INDEMNIFICATION.  Each Bank agrees to indemnify the Administrative 
Agent and the Collateral Agent in its respective capacities as such ratably 
according to such Bank's respective Commitment (or, if the Total Commitment 
has terminated, according to such Bank's respective Commitment immediately 
prior to such termination), from and against any and all liabilities, 
obligations, losses, damages, penalties, actions, judgments, suits, costs, 
reasonable expenses or disbursements of any kind whatsoever which may at any 
time (including, without limitation, at any time following the payment of the 
Obligations) be imposed on, incurred by or asserted against the 
Administrative Agent in its capacity as such in any way relating to or 
arising out of this Agreement or any other Credit Document, or any documents 
contemplated by or referred to herein or the transactions contemplated hereby 
or any action taken or omitted to be taken by the Administrative Agent under 
or in connection with any of the foregoing, but only to the extent that any 
of the foregoing is not paid by the Borrower or any of its Subsidiaries, 
PROVIDED that no Bank shall be liable to the Administrative Agent for the 
payment of any portion of such liabilities, obligations, losses, damages, 
penalties, actions, judgments, suits, costs, expenses or disbursements 
resulting solely from the Administrative Agent's gross negligence or willful 
misconduct.  If any


                                       -70-

<PAGE>

indemnity furnished to the Administrative Agent for any purpose shall, in the 
opinion of the Administrative Agent, be insufficient or become impaired, the 
Administrative Agent may call for additional indemnity and cease, or not 
commence, to do the acts indemnified against until such additional indemnity 
is furnished.  The agreements in this Section 10.07 shall survive the payment 
of all Obligations.

     10.08  THE ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.  The 
Administrative Agent and its affiliates may make loans to, accept deposits 
from and generally engage in any kind of business with the Borrower and its 
Subsidiaries as though not acting as Administrative Agent hereunder.  With 
respect to the Loans made by it and all Obligations owing to it, the 
Administrative Agent shall have the same rights and powers under this 
Agreement as any Bank and may exercise the same as though it were not the 
Administrative Agent, and the terms "Bank" and "Banks" shall include the 
Administrative Agent in its individual capacity.

     10.09  SUCCESSOR ADMINISTRATIVE AGENT.  The Administrative Agent may 
resign as the Administrative Agent upon 20 days' notice to the Banks and the 
Borrower.  Upon such resignation, the Required Banks shall, with the consent 
of the Borrower (such consent not to be unreasonably withheld), appoint from 
among the Banks a successor Administrative Agent for the Banks, whereupon 
such successor agent shall succeed to the rights, powers and duties of the 
Administrative Agent, and the term "Administrative Agent" shall include 
such successor agent effective upon its appointment, and the resigning 
Administrative Agent's rights, powers and duties as the Administrative Agent 
shall be terminated, without any other or further act or deed on the part of 
such former Administrative Agent or any of the parties to this Agreement.  
After the retiring Administrative Agent's resignation hereunder as the 
Administrative Agent, the provisions of this Section 10 shall inure to its 
benefit as to any actions taken or omitted to be taken by it while it was 
Administrative Agent under this Agreement.

     SECTION 11.  MISCELLANEOUS.

     11.01  PAYMENT OF EXPENSES, ETC.  The Borrower hereby agrees to:  (i) 
whether or not the transactions herein contemplated are consummated, pay all 
reasonable out-of-pocket costs and expenses of the Administrative Agent in

<PAGE>

amendment, waiver or consent relating to this Agreement or any other Credit 
Document; (iii) whether or not the transactions herein contemplated are

counsel for the Administrative Agent and for each of the Banks); (iv) pay and 
hold each of the Banks harmless from and against any and all present and 
future stamp and other similar taxes with respect to the foregoing matters 
and save each of the Banks harmless from and against any and all liabilities 
with respect to or resulting from any delay or omission to pay such taxes; 
and (v) indemnify the Administrative Agent and each Bank, and their 
respective officers, directors, employees, representatives and agents (each, 
an "indemnified person") from and hold each of them harmless against any 
and all losses, liabilities, claims, damages or expenses (collectively, 
"Claims") incurred by any of them as a result of, or arising out of, or in 
any way related to, or by reason of, any investigation, litigation or other 
proceeding (whether or not the Administrative Agent or any Bank is a party 
thereto) related to the entering into and/or performance of any Credit 
Document or the use of the proceeds of any Loans hereunder or the 
consummation of any other transactions contemplated in any Credit Document, 
including, without limitation, the reasonable fees and disbursements of 
counsel incurred in connection with any such investigation, litigation or 
other proceeding (but excluding any such losses, liabilities, claims, damages 
or expenses to the extent incurred by reason of the gross negligence or 
willful misconduct of the Person to be indemnified).

     11.02  RIGHT OF SETOFF.  In addition to any rights now or hereafter 
granted under applicable law or otherwise, and not by way of limitation of 
any such rights, upon the occurrence and continuance of an Event of Default, 
each Bank is hereby authorized at any time or from time to time, without 
presentment, demand, protest or other notice of any kind to the Borrower or 
to any other Person, any such notice being hereby expressly waived, to set 
off and to appropriate and apply any and all deposits (general or special) 
and any other Indebtedness at any time held or owing by such Bank (including, 
without limitation, by branches and agencies of such Bank wherever located) 
to or for the credit or the account of the Borrower against and on account of 
the Obligations and liabilities of the Borrower to such Bank or any other 
Bank under this Agreement or under any of the other Credit Documents, 
including, without limitation, all interests in Obligations of the Borrower 
purchased by such Bank or any other Bank pursuant to Section 11.06(b), and 
all other claims of any nature or description arising out of or connected 
with this Agreement or any other Credit Document, irrespective of whether or 
not such Bank shall have made any demand hereunder and although said 
Obligations, liabilities or claims, or any of them, shall be contingent or 
unmatured.  Each Bank is hereby designated the agent of all other Banks for 
purposes of effecting



                                       -72-

<PAGE>

set off pursuant to this Section 11.02 and the Borrower hereby grants to each 
Bank for such Bank's own benefit and as agent for all other Banks a 
continuing security interest in any and all deposits, accounts or moneys of 
the Borrower maintained from time to time with such Bank.

     11.03  NOTICES.  Except as otherwise expressly provided herein, all 
notices and other communications provided for hereunder shall be in writing 
(including telegraphic, telex, facsimile or cable communication) and mailed, 
telegraphed, telexed, telecopied, cabled or delivered, if to the Borrower, at 
the address specified opposite its signature below; if to any Bank, at its 
address specified for such Bank on Annex II hereto; or, at such other address 
as shall be designated by any party in a written notice to the other parties 
hereto. All such notices and communications shall be mailed, telegraphed, 
telexed, telecopied, cabled or sent by overnight courier and shall be 
effective when received.

     11.04  BENEFIT OF AGREEMENT.  (a)  This Agreement shall be binding upon 
and inure to the benefit of and be enforceable by the respective successors 
and assigns of the parties hereto; PROVIDED, HOWEVER, the Borrower may not 
assign or transfer any of its rights or obligations hereunder without the 
prior written consent of the Banks.  Each Bank may at any time grant 
participations in any of its rights hereunder or under any of its Notes to 
any bank or other financial institution; PROVIDED that in the case of any 
such participation, the participant shall not have any rights under this 
Agreement or any of the other Credit Documents, including rights of consent, 
approval or waiver (the participant's rights against such Bank in respect of 
such participation to be those set forth in the agreement executed by such 
Bank in favor of the participant relating thereto) and all amounts payable by 
the Borrower hereunder shall be determined as if such Bank had not sold such 
participation, except that the participant shall be entitled to receive the 
additional amounts under Sections 1.10, 1.11 and 3.04 of this Agreement to, 
and only to, the extent that such Bank would be entitled to such benefits if 
the participation had not been entered into or sold; and PROVIDED FURTHER, 
that no Bank shall transfer, grant or assign any participation under which 
the participant shall have rights to approve any amendment to or waiver of 
this Agreement or any other Credit Document except to the extent such 
amendment or waiver would (i) extend the final scheduled maturity of any Loan 
or Note in which such participant is participating or reduce the rate or 
extend the time of payment of interest thereon or Fees, or reduce the 
principal amount thereof, or increase such participant's participating 
interest in any Commitment or Loan over the amount thereof then in effect (it 
being understood that a waiver of any Default or Event of Default or of a 
mandatory reduction in the Total Commitment shall not constitute a change in 
the terms of any Commitment and that an increase in any Commitment shall be 
permitted without the consent of any participant if such participant's 
participation is not increased as a result thereof), (ii) release all or


                                      -73-

<PAGE>

any material portion of the Collateral (except as expressly provided in the 
Credit Documents) or (iii) consent to the assignment or transfer by the 
Borrower of any of its rights and obligations under this Agreement or any 
other Credit Document except in accordance with the terms hereof and thereof.

     (b)  Notwithstanding the foregoing, any Bank may assign all or a portion 
of its rights and obligations hereunder to a bank or other financial 
institution with the prior written consent of the Administrative Agent, which 
consent shall not be unreasonably withheld.  No assignment of less than all 
of a Bank's rights and obligations hereunder pursuant to the immediately 
preceding sentence shall, to the extent such transaction represents an 
assignment to an institution other than one or more Banks hereunder, be in an 
aggregate amount less than the minimum of $5,000,000 unless otherwise agreed 
to by the Administrative Agent and the Borrower in writing.  If any Bank so 
sells or assigns all or a part of its rights hereunder or under the Notes, 
any reference in this Agreement or the Notes to such assigning Bank shall 
thereafter refer to such Bank and to the respective assignee to the extent of 
their respective interests and the respective assignee shall have, to the 
extent of such assignment (unless otherwise provided therein), the same 
rights and benefits as it would if it were such assigning Bank.  Each 
assignment pursuant to this Section 11.04(b) shall be effected by the 
assigning Bank and the assignee Bank executing an Assignment and Assumption 
Agreement substantially in the form of Exhibit G (appropriately completed).  
At the time of any such assignment, (i) Annex I shall be deemed to be amended 
to reflect the Commitments, if any, and outstanding Loans of the respective 
assignee (which shall result in a direct reduction to the Commitments, if 
any, and outstanding Loans of the assigning Bank) and of the other Banks, 
(ii) if any such assignment occurs after the Effective Date, at the request 
of the assignor or the assignee the Borrower will issue new Notes to the 
respective assignee and to the assigning Bank in conformity with the 
requirements of Section 1.05 and (iii) the Administrative Agent shall receive 
from the assigning Bank and/or the assignee Bank or financial institution at 
the time of each assignment the payment of a nonrefundable assignment fee of 
$3,500, PROVIDED that such transfer or assignment will not be effective until 
recorded by the Administrative Agent on the Register pursuant to Section 
11.17 hereof.  At the time of each assignment pursuant to this Section 
11.04(b) to a Person which is not already a Bank hereunder and which is not a 
United States person (as such term is defined in Section 7701(a)(30) of the 
Code) for Federal income tax purposes, the respective assignee Bank shall 
provide to the Borrower and the Administrative Agent the appropriate Internal 
Revenue Service forms (and, if applicable a Section 3.04(b)(ii) Certificate) 
described in Section 3.04(b).  Each Bank and the Borrower agrees to execute 
such documents (including, without limitation, amendments to this Agreement 
and the other Credit Documents) as shall be necessary to effect the 
foregoing.  Promptly following any assignment pursuant to this Section 
11.04(b), the assigning Bank shall promptly notify the Borrower and the 
Administrative


                                      -74-

<PAGE>

Agent thereof.  Nothing in this Section 11.04 shall prevent or prohibit any 
Bank from pledging its Loans or Notes hereunder to a Federal Reserve Bank in 
support of borrowings made by such Bank from such Federal Reserve Bank.

     (c)  Notwithstanding any other provisions of this Section 11.04, no 
transfer or assignment of the interests or obligations of any Bank hereunder 
or any grant of participations therein shall be permitted if such transfer, 
assignment or grant would require the Borrower to file a registration 
statement with the SEC or to qualify the Loans under the "Blue Sky" laws of 
any State.

     (d)  Each Bank initially party to this Agreement hereby represents, and 
each Person that becomes a Bank pursuant to an assignment permitted by clause 
(b) above will upon its becoming party to this Agreement represent, that it 
is a commercial lender, other financial institution or other "accredited 
investor" (as defined in SEC Regulation D) which makes loans in the ordinary 
course of its business or is acquiring the Loans without a view to 
distribution of the Loans within the meaning of the federal securities laws, 
and that it will make or acquire Loans for its own account in the ordinary 
course of such business, PROVIDED that, subject to the preceding clauses (a) 
through (c), the disposition of any promissory notes or other evidences of or 
interests in Indebtedness held by such Bank shall at all times be within its 
exclusive control.

     11.05  NO WAIVER; REMEDIES CUMULATIVE.  No failure or delay on the part 
of the Administrative Agent or any Bank in exercising any right, power or 
privilege hereunder or under any other Credit Document and no course of 
dealing between the Borrower and the Administrative Agent or any Bank shall 
operate as a waiver thereof; nor shall any single or partial exercise of any 
right, power or privilege hereunder or under any other Credit Document 
preclude any other or further exercise thereof or the exercise of any other 
right, power or privilege hereunder or thereunder.  The rights and remedies 
herein expressly provided are cumulative and not exclusive of any rights or 
remedies which the Administrative Agent or any Bank would otherwise have.  No 
notice to or demand on the Borrower in any case shall entitle the Borrower to 
any other or further notice or demand in similar or other circumstances or 
constitute a waiver of the rights of the Administrative Agent or the Banks to 
any other or further action in any circumstances without notice or demand.

     11.06  PAYMENTS PRO RATA.  (a)  The Administrative Agent agrees that 
promptly after its receipt of each payment from or on behalf of the Borrower 
in respect of any Obligations of the Borrower, it shall distribute such 
payment to the Banks (other than any Bank that has consented in writing to

respective shares, if any, of the Obligations with respect to which such 
payment was received.

     (b)  Each of the Banks agrees that, if it should receive any amount 
hereunder (whether by voluntary payment, by realization upon security, by the 
exercise of the right of setoff or banker's lien, by counterclaim or cross 
action, by the enforcement of any right under the Credit Documents, or 
otherwise) which is applicable to the payment of the principal of, or 
interest on, the Loans or Fees, of a sum which with respect to the related 
sum or sums received by other Banks is in a greater proportion than the total 
of such Obligation then owed and due to such Bank bears to the total of such 
Obligation then owed and due to all of the Banks immediately prior to such 
receipt, then such Bank receiving such excess payment shall purchase for cash 
without recourse or warranty from the other Banks an interest in the 
Obligations of the Borrower to such Banks in such amount as shall result in a 
proportional participation by all of the Banks in such amount, PROVIDED that 
if all or any portion of such excess amount is thereafter recovered from such 
Bank, such purchase shall be rescinded and the purchase price restored to the 
extent of such recovery, but without interest.

furnished to the Banks pursuant hereto shall be made and prepared in 
accordance with GAAP or SAP, as the case may be, consistently applied 
throughout the periods involved (except as set forth in the notes thereto or 
as otherwise disclosed in writing by the Borrower to the Banks).  In 
addition, except as otherwise specifically provided herein, all computations 
determining compliance with Section 7, including definitions used therein, 
shall utilize accounting principles and policies in effect from time to time; 
PROVIDED that (i) if any such accounting principle or policy (whether GAAP or 
SAP or both) shall change after the Effective Date, the Borrower shall give 
reasonable notice thereof to the Administrative Agent and each of the Banks 
and if within 30 days following such notice the Borrower, the Administrative 
Agent or the Required Banks shall elect by giving written notice of such 
election to the other parties hereto, such computations shall not give effect 
to such change unless and until this Agreement shall be amended pursuant to 
Section 11.12 to give effect to such change, and (ii) if at any time the 
computations determining compliance with Section 7 utilize accounting 
principles different from those utilized in the financial statements then 
being furnished to the Banks pursuant to Section 6.01, such financial 
statements shall be accompanied by reconciliation work-sheets.

     (b)  All computations of interest on Loans and Fees hereunder shall be 
made on the actual number of days elapsed over a year of 360 days.

    11.14  DOMICILE OF LOANS.  Subject to Section 11.04, each Bank may

ruling applicable to such Bank and/or its affiliates, and (f) to any permitted
prospective or actual syndicate member or participant in the Loans, provided

Agreement.

    11.16  WAIVER OF JURY TRIAL.  EACH OF THE PARTIES TO THIS AGREEMENT
HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL


                                     -79
<PAGE>

BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING 
TO THIS AGREEMENT, THE CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED 
HEREBY OR THEREBY.

    11.17  REGISTER.  The Borrower hereby designates the Administrative
Agent to serve as its agent, solely for purposes of this Section 11.17, to
maintain a register (the "Register") on which it will record the Commitments
from time to time of each of the Banks, the Loans made by each of the Banks and
each repayment in respect of the principal amount of the Loans of each Bank.
Failure to make any such recordation, or any error in such recordation shall not
affect the obligations of the Borrower in respect of such Loans.  With respect
to any Bank, the transfer of the Commitments of such Bank and the rights to the
principal of, and interest on, any Loan made pursuant to such Commitments shall
not be effective until such transfer is recorded on the Register maintained by
the Administrative Agent with respect to ownership of such Commitments and Loans
and prior to such recordation all amounts owing to the transferor with respect
to such Commitments and Loans shall remain owing to the transferor.  The
registration of assignment or transfer of all or part of any Commitments and
Loans shall be recorded by the Administrative Agent on the Register only upon
the acceptance by the Administrative Agent of a properly executed and delivered
Assignment and Assumption Agreement pursuant to Section 11.04(b).  Coincident
with the delivery of such an Assignment and Assumption Agreement to the
Administrative Agent for acceptance and registration of assignment or transfer
of all or part of a Loan, or as soon thereafter as practicable, the assigning or
transferor Bank shall surrender the Note evidencing such Loan, and thereupon one
or more new Notes in the same aggregate principal amount shall be issued to the
assigning or transferor Bank and/or the new Bank.  The Borrower agrees to
indemnify the Administrative Agent from and against any and all losses, claims,
damages and liabilities of whatsoever nature which may be imposed on, asserted
against or incurred by the Administrative Agent in performing its duties under
this Section 11.17 (but excluding any such losses, liabilities, claims, damages
or expenses to the extent incurred by reason of the gross negligence or willful
misconduct of the Administrative Agent).

    11.18  COLLATERAL RELEASE.  On the Collateral Release Date, so long as
no Default or Event of Default shall exist at such time, the Pledge Agreement
shall be terminated and no longer be of any force or effect and the Collateral
Agent is hereby authorized and directed at such time to take such actions as are
appropriate to give effect to such termination and release.

1.  REINSURED desires to cede, and REINSURER desires to accept, reinsurance of
    the certain deferred annuity policies as specified in this Agreement,
    subject to the terms and conditions set forth herein.

2.  To facilitate the profitable performance of the policies reinsured
    hereunder for the mutual benefit of the REINSURED and the REINSURER, the
    REINSURED and the REINSURER desire that the same investment manager manage
    the investment and reinvestment of the assets underlying the reinsured
    policies according to a common investment policy.

<PAGE>

3.  To facilitate the profitable performance of the policies reinsured
    hereunder for the mutual benefit of the REINSURED and the REINSURER, the
    REINSURED and the REINSURER desire that the companies establish a
    management committee to oversee the investment policy for the assets
    underlying the reinsured policies, to review investment performance and to
    review other matters of mutual interest.


                           B.  REINSURANCE COVERAGE

1.  All of the deferred annuity policies (referred to herein as "the policies")
    issued by the REINSURED during the term of this Agreement on the forms
    listed in Schedule I shall be reinsured with the REINSURER automatically in
    accordance with the REINSURED'S underwriting rules applicable to such
    policies.

2.  The reinsurance shall cover the quota share of the policies as specified in
    Schedule II.  All benefits provided by the policies shall be reinsured
    hereunder in the portion specified in Schedule II.

3.  The liability of the REINSURER shall begin simultaneously with that of the
    REINSURED but in no event prior to the effective date of this Agreement. 
    Reinsurance with respect to any policy shall not be in force and binding
    unless the insurance issued directly by the REINSURED is in force and
    unless the issuance and delivery of such insurance constituted the doing of
    business in a state of the United States of America (including the District
    of Columbia) in which the REINSURED was properly licensed.

4.  Reinsurance under this Agreement shall be on the coinsurance plan and shall
    follow the forms of the REINSURED.

5.  The reinsurance under this Agreement with respect to any policy shall be
    maintained in force without reduction so long as the liability of the
    REINSURED under such policy reinsured hereunder remains in force without
    reduction, unless reinsurance is terminated or reduced as provided herein.


                                       2
<PAGE>

6.  Internal Replacements - Any internal program for the replacement of
    reinsured contracts must be approved by the Management Committee. 
    Replacement business shall continue to be subject to this Coinsurance
    Agreement unless the REINSURER decides not to reinsure the replaced
    business.


                      C.  PLACING REINSURANCE IN EFFECT


Reinsurance shall become effective simultaneously with the liability of the 
REINSURED, provided however, that the REINSURED shall give notification of 
such reinsurance to the REINSURER no later than the monthly report set out in 
Schedule III.


                          D.  PAYMENTS BY REINSURED


The REINSURED shall pay the REINSURER reinsurance premiums equal to the 
REINSURER's quota share of the gross contributions or premiums the REINSURED 
receives on the policies on and after the effective date of this Agreement.


                          E.  PAYMENTS BY REINSURER


1.  BENEFITS

    The REINSURER shall pay the REINSURED the REINSURER's quota share of:

    (a)  the death benefits (including interest paid beyond the date of death)
         paid by the REINSURED, without deduction for reserves (after taking
         into account surrender charges, if any); and

    (b)  the net cash surrender values paid by the REINSURED;


                                       3
<PAGE>

    (c)  the net cash surrender calculated on anuitizing policies as if they
         had been surrendered for cash;

    (d)  the return of premiums, net policy expense allowances, to the
         policyholder of a canceled policy paid by the REINSURED.

2.  POLICY EXPENSE ALLOWANCES

    The REINSURER shall pay the REINSURED the allowances and expense
    reimbursements as defined in Schedule VI on the REINSURER's quota share of
    the policies.  These allowances and expense reimbursements shall be netted
    on at least a weekly basis from cash flow, if sufficient, before the
    balance is transferred to the trust account.  If insufficient, the
    REINSURER shall be billed for the net amount due.

3.  PROFIT SHARING

    The REINSURER shall pay to REINSURED an experience refund at the end of
    each seven year policy term if statutory profits earned during a given 7
    year term, calculated assuming all in force policies surrender at the end
    of the term, exceed 10% of the premium at the beginning of the term.  Fifty
    percent (50%) of any excess profit above 10% of premium on the REINSURER's
    quota share of the business will be refunded to the REINSURED by the
    REINSURER as an experience refund at the end of a given 7 year term.  The
    experience refund calculation will be done for all policies issued in a
    given calendar year and paid within 30 days after the end of the year for
    which it is being calculated.


                               F.  TERMS OF REINSURANCE


1.  AMOUNTS DUE REINSURED OR REINSURER

    Except as otherwise specifically provided herein, all amounts due to be
    paid to the REINSURER or the REINSURED shall be determined on a net basis
    as of the issue day of every calendar week to which such amount is
    attributable.  The issue day for issues of 


                                       4
<PAGE>

    a given week will initially be the Thursday of the following week 
    subject to modifications by the REINSURED upon agreement by the 
    REINSURER.  If the Thursday is a bank holiday or if the REINSURED feels 
    another day should be used, the REINSURED will notify the REINSURER and 
    they will mutually define another day of the week as the issue day.  All 
    amounts shall be due and accrued as of such date.  The payment of such 
    amounts shall be submitted in accordance with the provisions of Section 
    F, paragraph 2.  All settlements of account between the REINSURER and 
    the REINSURED shall be made in cash or its equivalent.  Book value and 
    statutory reserves shall be determined in accordance with the 
    REINSURED's standard practices.

2.  PAYMENT DATES

    (a)  The REINSURED shall submit a Periodic Report substantially in accord
         with the reports listed in Schedule III.  Any amounts indicated in the
         Periodic Report as due the REINSURER shall accompany such report.

    (b)  Not later than fifteen (15) days after the receipt of the Periodic
         Report, any amounts indicated in the Periodic Report as due the
         REINSURED shall be paid by the REINSURER.

    (c)  Not later than twenty (20) days after the end of each calendar
         quarter, the REINSURED shall submit to the REINSURER a Quarterly
         Report substantially in accord with Schedule IV.

    (d)  Not later than twenty (20) days after the end of each calendar year,
         the REINSURED shall submit to the REINSURER an Annual Report
         substantially in accord with Schedule V.

In the event that actual numbers are not available, reasonable estimates will 
be used and appropriate adjustments will be made within 30 days or on the 
next report whichever is sooner.

In addition the REINSURED agrees to work with the REINSURER and the REINSURER 
agrees to work with the REINSURED to perform cash flow analysis as required. 
This would 


                                       5

<PAGE>

include providing copies of any work (e.g. New York Regulation 126 actuarial 
opinion) performed by the REINSURED and the REINSURER to analyze reserve 
adequacy as this work is being developed.

3.  SECTION 1.848-2(g)(8) ELECTION

    If the Business reinsured hereunder includes for U.S. Federal income tax
    purposes Specified Insurance Contracts pursuant to Section 848 of the
    Internal Revenue Code or the Final Income Tax Regulations thereunder, the
    REINSURED and the REINSURER, with respect to this Agreement, agree to make
    the election provided in Section 1.848-2(g)(8) of the Final Income Tax
    Regulations issued December 28, 1992 under Section 848 of the Internal
    Revenue Code of 1986.  The specifics on this election are set forth in
    Schedule IX.

4.  OFFSET

    Any debits or credits, matured or unmatured, liquidated or unliquidated,
    regardless of when they arose or were incurred, in favour of or against
    either the REINSURED or the REINSURER with respect to this Agreement are
    deemed mutual debits or credits, as the case may be, and shall be set off,
    and only the balance shall be allowed or paid.


                       G.  TRUST AGREEMENT AND ASSET MANAGEMENT


1.  The REINSURER shall enter into a trust agreement with the REINSURED and
    State Street Bank and Trust Company, as trustee for establishment of a
    trust.

2.  The REINSURED shall deposit premium payments as described in Section D,
    less Payments by REINSURER as described in Section E, directly into the
    trust account.  Deposit by the REINSURED of amounts calculated pursuant to
    this Agreement directly into the trust shall constitute payment by the
    REINSURED of each premium to the REINSURER and shall satisfy the
    REINSURED's obligation hereunder to pay such premium to the REINSURER.


                                       6
<PAGE>

3.  The assets in the trust account shall be invested and reinvested pursuant
    to the investment policy ("Investment Policy") set forth in Addendum I as
    such policy may be modified from time to time by the Management Committee
    as provided in Section J.

4.  If this Agreement is terminated with respect to new policies pursuant to
    Section W, and all reinsured policies have passed their second anniversary,
    the trust account shall be managed to maintain the aggregate book value of
    assets in the trust account at a level at least equal to the statutory
    reserve of the policies supported by the assets in the account.

5.  The REINSURED and the REINSURER shall share all trustee/custodial fees and
    expenses paid for the trust account.

6.  The REINSURED and REINSURER agree that the assets in the trust account,
    notwithstanding any other provisions in this Agreement, shall be utilized
    and applied by the REINSURED or any successor by operation of law of the
    REINSURED, including, without limitation, any liquidator, rehabilitator,
    receiver or conservator of the REINSURED, without diminution because of
    insolvency on the part of the REINSURED or the REINSURER to satisfy the
    obligations of the REINSURED, including expenses, with respect to the
    policies reinsured under this Agreement.

7.  At anytime when the book value of assets in the trust exceed the statutory
    reserve required for the policies supported by the assets in the account,
    the REINSURED and the REINSURER, upon mutual agreement, can withdraw their
    respective quota share of assets exceeding the statutory reserves from such
    account.

    If, at the end of any calendar quarter, the statutory reserve required for
    the policies supported by the assets in the trust account exceeds the book
    value of assets in that account by an amount equal to or greater than 
    one-quarter of one percent (.25%) of the required reserve amount, the 
    REINSURER and the REINSURED shall immediately deposit cash in an amount 
    equal to their respective quota share of the shortfall into that account.


                                       7
<PAGE>

    For purposes of this section, book value and statutory reserves shall be
    determined in accordance with the REINSURED's standard practice, unless the
    parties agree otherwise in writing.

8.  In the event that any amount is withdrawn from the trust account pursuant
    to Paragraph 6 of this Section, the REINSURED shall promptly return to the
    trust account any amounts that are subsequently determined not to be
    withdrawn in compliance with the provisions of this Agreement.

9.  Transfer to the REINSURED by the trustee of the assets withdrawn from the
    trust account pursuant to Paragraph 6 above, shall constitute payment by
    the REINSURER pursuant to this Agreement and shall discharge the REINSURER
    of the obligation which gave rise to the withdrawal to the extent of the
    amount withdrawn, provided however, the REINSURER may later contest whether
    it had failed to reimburse or pay the REINSURED as required by this
    Agreement.

10. The REINSURER shall not retrocede any portion of its quota share of the
    policies in a manner which would require the transfer of assets from the
    trust to the retrocessionaire.


                       H.  PORTFOLIO MANAGEMENT AGREEMENT


1.  The REINSURER shall enter into an Portfolio Management Agreement with Delta
    Life and Annuity Company ("DLAC") pursuant to which DLAC shall manage the
    investment and reinvestment of the assets in the trust account.  DLAC shall
    invest the assets pursuant to the terms of the Investment Policy (Addendum
    I) as such policy may be modified from times to times by the Management
    Committee as provided in Section J hereof and the terms and conditions of
    the Portfolio Management Agreement.

2.  The REINSURER shall be responsible for paying DLAC a monthly fee as
    specified in the Portfolio Management Agreement.


                                       8
<PAGE>

3.  If reinsurance pursuant to this Agreement terminates and there is no
    reinsurance in force between the REINSURED and the REINSURER hereunder,
    DLAC (or any successor Portfolio Manager) and the REINSURER each shall have
    the right to terminate the Portfolio Management Agreement immediately.  The
    Portfolio Management Agreement shall contain such additional termination
    provisions as the REINSURER and DLAC may agree.

4.  If the Management Committee determines that the performance of the
    Portfolio Manager is not satisfactory to support the business reinsured
    hereunder, the REINSURER shall have the right to terminate the Portfolio
    Management Agreement upon 30 days prior written notice to the Portfolio
    Manager.

5.  In the event the Portfolio Management Agreement terminates while
    reinsurance remains in force hereunder, a successor Portfolio Manager shall
    be proposed by the REINSURED subject to approval by the REINSURER.


        I.  SPREADS DEDUCTED FROM THE INDEX OR INDICES ON THE POLICIES
                                       

First year and renewal spreads on the policies shall be set in accordance with
the provisions of Schedule VII.


                               J.  MANAGEMENT COMMITTEE


1.  A Management Committee consisting of four representatives from the
    REINSURED and the REINSURER shall be established.  Two representatives from
    each company shall be elected by the Presidents of the respective companies
    for one year terms.  The Management Committee shall function as a general
    communication vehicle and decision maker as set out below.

2.  The Management Committee shall meet no less frequently than annually.  Any
    member of the Management 


                                       9
<PAGE>

    Committee may call a meeting upon ten (10) days prior written notice unless
    waived in writing.

3.  In addition to functioning as a general communication vehicle, the role of
    the Management Committee is to deal with issues that arise in connection
    with the following items:

    1.   To determine any adjustments to be made to the option price formula.

    2.   To decide upon modification of the Investment Policy as referred to in
         Section H.

    3.   To approve any material changes in products, product pricing, or
         market approach.

    4.   To periodically establish portfolio management guidelines with respect
         to the realization of net capital gains and losses during defined
         periods.

    5.   To establish a change in strategy and guidelines with respect to the
         use of options, futures, caps and other derivative investment products
         including inclusion or exclusion of counterparties for the call
         options.

    Decisions of the Management Committee shall require the unanimous agreement
    of all members of the committee.

4.  In the event the Management Committee fails to reach unanimous agreement on
    items, there shall be no change in those items or the treatment under the
    terms of this Agreement of the issues and matters which are subject of
    those items.


           K.  CLAIMS, LITIGATION, UNUSUAL EXPENSES AND ADJUSTMENTS


1.  Any Unusual Expenses incurred by the REINSURED in defending or
    investigating a claim for policy liability or rescinding a policy reinsured
    hereunder shall be participated in by the REINSURER in the 


                                      10
<PAGE>

    same proportion as its reinsurance bears to the total insurance under 
    such policy.

2.  For purposes of this Agreement, it is agreed that expenses, attorney's
    fees, and interest imposed against the REINSURED and arising solely out of
    a settlement or a judgement rendered against the REINSURED in a suit for
    policy benefits reinsured hereunder shall be considered Unusual Expenses.

3.  In no event, however, shall the following categories of expenses or
    liabilities be considered for purposes of this Agreement as "Unusual
    Expenses":

    (a)  routine investigative or administrative expenses; and

    (b)  expenses, fees, settlements, or judgments arising out of or in
         connection with claims against the REINSURED for punitive or exemplary
         damages; and

    (c)  expenses, fees, settlements, or judgments arising out of or in
         connection with claims made against the REINSURED and based on alleged
         or actual bad faith, or willful misconduct;

    and the REINSURER shall have no liability under this Agreement for expenses
    or liabilities described in the above subparagraphs 3(a), (b) and (c).

4.  Litigation. If the REINSURED contests a claim which results in actual or
    threatened litigation, the REINSURED shall notify the REINSURER.  The
    REINSURER may elect not to participate in the contest and pay its quota
    share of the liabilities on the policy being contested within 20 days of
    such notice.  In such event, the REINSURED shall be solely responsible for
    the conduct of the litigation and for all expenses and liabilities incurred
    in connection with such claim and the REINSURER shall have no further
    liability or responsibility to pay or share in such expenses or
    liabilities.

    In all cases, the REINSURED shall be solely responsible for the management
    of each and every claim or litigation arising out of or in connection with
    the 


                                      11
<PAGE>

    policies reinsured hereunder, and shall have all power and authority to
    settle or dispute any claim and to direct the course of any such
    litigation.  Consistent with the terms of this paragraph K, REINSURER shall
    be bound by the terms of any such settlement or the outcome of any such
    litigation.

    In the event REINSURED shall become aware of any actual or threatened
    litigation in which the claimant or adverse party is asserting direct
    liability of the REINSURER with respect to a policy reinsured hereunder,
    the REINSURED shall promptly notify REINSURER.  The expenses incurred by
    the REINSURER with respect to such litigation shall be shared by the
    REINSURED in the same proportion as its quota share of the insurance
    liability under such policy.


                               L.  ANNUITIZATION


The REINSURED shall recapture reinsurance with respect to all reinsured 
policies upon their annuitization.  The REINSURER shall pay the REINSURED the 
cash surrender value less any surrender charges according to the terms of the 
respective policy being recaptured by the REINSURED upon annuitization 
pursuant to this Section.  Such payment shall reflect the entire 
consideration to be paid in regard to such recapture.


                                  M.  ERRORS


If either the REINSURED or the REINSURER shall fail to perform an obligation 
under this Agreement and such failure shall be the result of an error on the 
part of the REINSURED or the REINSURER, such error shall be corrected by 
restoring both the REINSURED and the REINSURER to the positions they would 
have occupied had no such error occurred; an "error" is a clerical mistake 
made inadvertently and excludes errors of judgment and all other forms of 
error.


                     N.  AUDIT OF RECORDS AND PROCEDURES


                                      12
<PAGE>

The REINSURER and the REINSURED each shall have the right to audit, at the 
office of the other, all records and procedures relating to reinsurance under 
this Agreement.  The expenses of any such audit shall be born by the party 
initiating the audit.


                              O. CONFIDENTIALITY


The REINSURED and REINSURER each agree that all information, including but 
not limited to customer information, is proprietary in nature.  Such 
information shall be received by the REINSURER in strict confidence, shall be 
used for the purpose of this Agreement only and no such information shall be 
disclosed to a third party by the recipient party, its agents, or employees 
without the prior written consent of the REINSURED.  Except as may be 
necessary by reason of legal or regulatory requirements, each party hereto 
agrees to take all reasonable precautions to prevent the disclosure to 
outside parties of such information.


                               P.  ARBITRATION


1.  If the REINSURED and the REINSURER cannot mutually resolve a dispute which
    arises out of or relates to this Agreement, the dispute shall be decided
    through arbitration as set forth in Schedule VIII.  The arbitrators shall
    be impartial and shall base their decision on the terms and conditions of
    this Agreement.  In the event that an interpretation of the terms and
    conditions of this Agreement does not explicitly dispose of an issue in
    dispute between the parties, then the arbitrators may base their decision
    on the customs and practices of the insurance and reinsurance industry
    rather than solely on a strict interpretation of applicable law.  There
    shall be no appeal from the arbitrators' decision.  Any court having
    jurisdiction over the subject matter and the parties may reduce the
    arbitrators' decision to judgment.

2.  The parties intend this Section to be enforceable in accordance with the
    Federal Arbitration Act (9 


                                      13
<PAGE>

    U.S.C. Section 1 et seq.), including any amendments to that Act which are
    subsequently adopted.  The parties further intend that the issue of 
    arbitrability of any dispute hereunder shall be resolved pursuant to the 
    Federal Arbitration Act and federal court decisions construing the Federal
    Arbitration Act, and not pursuant to the law of any state.  In the event 
    that either party refuses to submit to arbitration as required by 
    Paragraph 1, the other party may request a United States Federal District 
    Court to compel arbitration in accordance with the Federal Arbitration Act.
    Both parties consent to the jurisdiction of such court to enforce this 
    Section and to confirm and enforce the performance of any award of the 
    arbitrators.

3.  The obligations of the parties to arbitrate disputes hereunder pursuant to
    this Section shall survive the termination of this Agreement.


                                Q.  INSOLVENCY


1.  The portion of any risk or obligation assumed by the REINSURER, when such
    portion is ascertained, shall be payable on demand of the REINSURED at the
    same time as the REINSURED shall pay its net retained portion of such risk
    or obligation, with reasonable provision for verification before payment,
    and the reinsurance shall be payable by the REINSURER, on the basis of the
    liability of the REINSURED under the policies reinsured hereunder without
    diminution because of the insolvency of the REINSURED.  In the event of
    insolvency and the appointment of a conservator, liquidator or statutory
    successor of the REINSURED, such portion shall be payable to such
    conservator, liquidator or statutory successor immediately upon demand,
    with reasonable provision for verification, on the basis of claims allowed
    against the REINSURED by any court of competent jurisdiction or by any
    conservator, liquidator or statutory successor of the REINSURED having
    authority to allow such claims, without diminution because of such
    insolvency or because such conservator, liquidator or statutory successor
    has failed to pay all or a portion of any claims.


                                      14
<PAGE>

2.  The REINSURED's conservator, liquidator, or statutory successor shall give
    the REINSURER written notice of the pendency of a claim against the
    REINSURED indicating the policy reinsured, within a reasonable time after
    such claim is filed.  The REINSURER may interpose, at its own expense, in
    the proceeding where such claim is to be adjudicated, any defense or
    defenses which the REINSURER may deem available to the REINSURED, or its
    conservator, liquidator or statutory successor.

3.  Any expense incurred by the REINSURER pursuant to paragraph 2, above, shall
    be payable subject to court approval out of the estate of the REINSURED as
    part of the expense of conservation or liquidation to the extent of the
    REINSURER's quota share of the benefit which may accrue to the REINSURED in
    conservation or liquidation, solely as a result of the defense undertaken
    by the REINSURER.  Where two or more reinsurers are participating in the
    same claim and a majority in interest elect to interpose defense to such
    claim, the expense shall be apportioned in accordance with the terms of
    this Agreement as though such expense had been incurred by the REINSURED.


                           R.  PARTIES TO AGREEMENT


This is an agreement for indemnity reinsurance solely between the REINSURED and
the REINSURER.  The acceptance of reinsurance hereunder shall not create any
right or legal relation whatever between the REINSURER and the insured or the
beneficiary under any policy reinsured hereunder, and the REINSURED shall be and
remain solely liable to such insured or beneficiary under any such policy.


                                S.  ASSIGNMENT


None of the rights and obligations under this Agreement may be assigned by
either the REINSURED or the REINSURER, without the prior written consent of the
other party.


                                      15
<PAGE>

                              T.  EFFECTIVE DATE


The effective date of this Agreement is 12:01 a.m., February 1, 1996.

                          U.  DURATION OF AGREEMENT

1.  Except as otherwise provided herein, this Agreement shall be unlimited in
    duration.

2.  Except in the case mentioned in Schedule VII, this Agreement may be
    terminated with respect to new policies by either the REINSURER or the
    REINSURED any time after the earlier of (a) or (b), where (a) is February
    1, 1999, and (b) is when the amount of the gross contributions and premiums
    received by the REINSURER pursuant to the policies exceeds $300 million. 
    Such termination shall be effective immediately upon receipt of written
    notice of termination by one party from the other party.

3.  The REINSURED shall have the right to terminate this Agreement and
    recapture the reinsured business as to any policy reinsured hereunder at
    any time after such reinsured policy has been in force for a period of
    fourteen (14) years.  Recapture shall be based upon terms to be negotiated
    at the time of termination.  Several general principles shall be followed
    at any recapture negotiation.

    (a)  Recapture must be elected with respect to all policies issued from a
         same calendar year then in force which are reinsured under this
         Agreement.

    (b)  The consideration to be paid shall reflect the present value of
         profits on the Recaptured Business.

    (c)  The profit projection shall reflect the cost of all significant risks. 
         These risks are primarily risks associated with defaults, interest
         rate movements, and the index movements.

4.  The REINSURED shall have the right to terminate this Agreement and
    recapture all reinsurance hereunder in 


                                      16
<PAGE>

    the event the REINSURER becomes subject to any insolvency or similar 
    proceeding.  In the event the REINSURED exercises this right to 
    terminate and recapture reinsurance, the REINSURED shall reimburse the 
    REINSURER for any unamortized excess first-year expense allowances, and 
    the REINSURER shall transfer the assets in the trust to the REINSURED, 
    after first having deposited or withdrawn (with the REINSURED's consent) 
    sufficient assets to or from the trust such that the statutory book 
    value of assets in the trust is equal to the statutory liability 
    (statutory reserve plus interest maintenance reserve) recaptured.

5.  The termination of this Agreement or of the reinsurance in effect under
    this Agreement shall not extend to or affect any of the rights or
    obligations of the REINSURED and the REINSURER applicable to any period
    prior to the effective date of such termination.  In the event that,
    subsequent to the termination of this Agreement, an adjustment is made
    necessary with respect to any accounting hereunder, a supplementary
    accounting shall take place.  Any amount owed to either party by reason of
    such supplementary accounting shall be paid promptly upon the completion
    thereof.

6.  After the effective date of any recapture, the REINSURER shall no longer
    share in the experience on the block, including profits and/or losses.


                          V.  REGULATORY COMPLIANCE


If the overall structure or a particular clause of this Agreement causes a
regulatory issue with any of the states in which the REINSURED or the REINSURER
are licensed, both parties agree to make their best effort to resolve the
situation.

                                       
                                W.  AGREEMENT


This Agreement, together with the trust agreement established pursuant to
Section G and the Portfolio Management 


                                      17
<PAGE>

Agreement established pursuant to Section H constitutes the entire agreement 
between the REINSURED and the REINSURER with respect to the business being 
reinsured hereunder; they supersede any prior oral or written agreements with 
respect to the business being reinsured hereunder other than as expressed in 
this Agreement, together with the trust agreement pursuant to Section G and 
the Portfolio Management Agreement established pursuant to Section H.  Any 
change or modification to this Agreement shall be null and void unless made 
by amendment to the Agreement signed by both the REINSURED and the REINSURER.

Governing Law.  This agreement shall be governed by and construed in accordance
with the laws of the State of Tennessee without regard to principles of
conflicts of law contained therein.

                                  ADDENDUM I


INVESTMENT POLICY - INDEX PRODUCTS

PORTFOLIO OBJECTIVES


The indexed deferred annuity account is managed to provide a guaranteed 
minimum return with additional interest rate guarantees liked to the 
performance of the index or indices as defined by the respective policy forms 
reinsured under this Agreement.  The product is designed with significant 
surrender charges and a fixed maturity (rollover) period.  The goal will be a 
fixed income portfolio that closely matches projected guaranteed minimum 
liability cash flows.  The index linked additional interest rate guarantees 
will be hedged using a combination of custom index call and put options.

PERMITTED INVESTMENTS

(1) Debentures issued, secured or guaranteed by the U.S. Government, 
government agencies or instrumentalities (including original issue zero 
coupon and stripped principal or interest payments from original coupon 
bearing debentures).

(2) Public corporate and taxable municipal securities rated A3/A- or higher.

(3) Custom options (calls and puts) with approved counterparties designed to 
hedge index linked additional interest liability under the annuity contracts.


MATURITY, LIQUIDITY & DURATION GUIDELINES


(1) A target fixed income portfolio modified duration will be established by 
the Management Committee using periodic cash flow testing and assuming all 
policies are redeemed at the end of each 7 year term.  The fixed income 
portfolio's actual duration will not vary from the target by more than one 
half year.


                                      20
<PAGE>

(2) Notwithstanding the fixed income portfolio duration constraint described 
in (1) above, no fixed income investments will be made which have a final 
maturity date exceeding the next renewal date of the underlying liabilities 
by more than one year.

(3) The Management Committee will direct periodic cash flow testing of the 
block of business with projections utilizing various interest rate and 
indices scenarios.

(4) Liquidity requirements will be defined by the Management Committee from 
time to time.  It is understood that DLAC will make every effort to be fully 
invested at all times.  To facilitate trades, there will be times where DLAC 
will have to use additional cash or will not make full use of all of the 
available cash to purchase bulk amounts of bonds in a given week.  The 
REINSURER will pay an overnight rate to the REINSURED on cash borrowed to 
complete a trade.  The net amount will be computed and settled quarterly.  
DLAC may, subject to approval from the Management Committee, establish 
collateral (REPO) credit lines to provide temporary liquidity in lieu of the 
disposition of assets.


ADDITIONAL INVESTMENT CONSTRAINTS


- -   Overall credit quality of the fixed income portfolio to be "AA3/AA-" or
    better.

- -   All fixed income investments to be U.S. dollar denominated.

- -   Minimum liquidity provisions to be maintained as defined by the Management
    Committee.

- -   From time to time, DLAC may present revised guidelines to the Management
    Committee for consideration.

- -   Asset Class Weightings (based on market value):

         U.S. Government and Agency bonds   20 - 100%
         Public taxable municipal bonds      0 - 15%
         Public corporate bonds              0 - 80%


                                      21
<PAGE>

- -   Corporate Sector Weightings (based on market value):

    Industrials              maximum of 40%
    Finance                  maximum of 30%
    Utilities                maximum of 30%
    Yankees                  maximum of 10%
    Foreign Governments      maximum of 10%

- -   Issuer Limitations (other than U.S. Government and Agencies):

         Rating              minimum rating of A3/A-

    Issuer Concentration (based on market value)

              Aaa/AAA             3.00%
              Aa3/AA- and above   2.00%
              A3/A-     and above      1.25%

    For the first 3 months of the Agreement, the reinsured share of the
    portfolio will have an assumed growth level of $100 million.  This means
    that on the REINSURER's share of the assets, the maximum amount to be
    invested in a A3 bond from the same issuer is $1.25 million.  This $100
    million assumed growth level will be estimated again by the REINSURER and
    the REINSURED at the end of the first 3 months based on the business volume
    issued at that time.

- -   Taxable municipal bonds must be general obligations or essential service
    revenue bonds.  If insured, the underlying rating must be investment grade,
    the insurer must be rated Aa3/AA- or higher, and all other issuer
    limitations apply.

- -   All hedging activity will be conducted with counterparties (or guarantors)
    with a minimum rating of A3 from Moody's or A- from S&P and approved by the
    Management Committee.  All hedging activity will be governed by the
    policies and procedures outlined in Exhibit I of this Agreement.

- -   It is understood that, as this is a new and growing portfolio, compliance
    with all the guidelines outlined above will not be possible immediately
    from inception.  While best efforts will be made to 


                                      22
<PAGE>

    achieve and maintain compliance as soon as possible, with respect to issuer
    concentration, asset class weightings, and corporate sector weightings, 
    compliance requirements will be waived for a period not exceeding one year 
    from inception.

- -   The assets held in the fixed income portfolio shall be classified as
    "Available for Sale" as defined under FASB 115 for GAAP accounting
    purposes.

                   ALLOWANCES AND EXPENSE REIMBURSEMENTS


The REINSURER shall pay to the REINSURED the following expense allowances:

1. Commission of 7% of premium on the initial policy term.  This is 
consistent with the pricing assumption of the REINSURED and what is actually 
paid on new sales.  These commissions are fully charged back on surrenders 
occurring in the first year of issue and will be paid back to the REINSURER 
on surrenders.

2. Agent Travel Commission of 0.35% of initial policy term premium.

If the REINSURED decides to change the commission rate or the bonus rate, the 
Management Committee would have to review the expense allowances and the 
spread management for this Agreement.

3. Commission of 3.5% of premium for a subsequent ("renewed") policy term in 
the first renewal year and 0.6% of premium in the renewal years after the 
first renewal year of each subsequent policy term.

4. Quota share of issue expense of $358 per policy.

5. Quota share of annual administrative expenses of $140.00 per policy in 
force.

The initial policy term allowances shall be netted from cash flows, if 
sufficient, before the balance is transferred to the trust account.  If the 
cash flows are insufficient, the REINSURER shall be billed for the net amount 
due. The annual allowances are to be taken out of the trust account on a 
monthly basis.  Each renewal allowance is to be charged against all reinsured 
policies issued on the same date.

                                  SCHEDULE VII

Spread Management

Definition of Terms for Schedule VII:

         Expense reimbursed is expressed as a percentage of premium and it
         includes commission and other issue expenses.  At inception of the
         Agreement, it is equal to 8.245% of premium.

         Yield is the effective annual yield that can be earned on a AA- rated
         7 year bond purchased to comply with the Investment Policy.  The yield
         can be viewed as being the 7 year Treasury yield plus an average
         spread earned on a 7 year "AA-" rated corporate bond.

         A bucket is defined as all policies issued on the same date.

         The Portfolio is defined as all policies issued since the inception of
         this Agreement.

         The Investment Policy is the investment policy set forth in Addendum I
         hereto.


    1.   REINSURED POLICIES IN INITIAL POLICY TERM

         a) Each Bucket

         For each bucket, the REINSURED shall manage the spread deducted from
         the effective yield calculated using the index defined in the
         underlying policy such that the dollar amount remaining after paying
         for the options and other issue expenses reimbursed under this
         Agreement be invested in bonds with an effective yield large enough to
         grow to 115.2% of the original premium at the end of a 7 year period. 
         In all instances, these bonds will be purchased in compliance with the
         Investment Policy.

         The formula for the maximum price to paid on the option is:


                                      30
<PAGE>

         Option Price less than/or equal to 1- expense reiumbursed -
             115.2%   
         -------------
         ((1+Yield)^7)

         If the price of the option is greater than 20% of the premium, the
         REINSURED will require prior approval from the REINSURER before
         issuing more new business.

         b) Entire Portfolio

         Similarly for the entire portfolio, the REINSURED shall manage the
         spread deducted from the effective yield calculated using the index
         defined in the underlying policy such that the dollar amount remaining
         after paying for the options and other issue expenses reimbursed under
         this Agreement be invested in bonds with an average effective yield
         large enough to grow to 116.25% of the original premiums at the end of
         a 7 year period.

         The formula for the average price to be paid on the option is:

         Average Option Prices less than/or equal to 1- expense reiumbursed -
             116.25%    
         ----------------
         ((1+Avge Yld)^7)

         where, the average option price is weighted by the premium volume and
         the average yield is weighted by the initial book value of the bonds.

         If the REINSURED does not comply to the above formula, the REINSURER
         reserves the right to terminate this Agreement with respect to new
         business with 10 days prior written notice.

    2.   REINSURED POLICIES IN SUBSEQUENT POLICY TERMS

         The REINSURED shall set renewal spread under the same conditions as
         the initial policy term spreads unless a different method is set by
         the Management Committee.


                                      31
<PAGE>

                                SCHEDULE VIII

                             ARBITRATION SCHEDULE

To initiate arbitration, either the REINSURED or the REINSURER shall notify 
the other party in writing of its desire to arbitrate, stating the nature of 
its dispute and the remedy sought.  The party to which the notice is sent 
shall respond to the notification in writing within ten (10) days of its 
receipt.

The arbitration hearing shall be before a panel of three arbitrators, each of 
whom must be a present or former officer of an insurance or reinsurance 
company. An arbitrator may not be a present or former officer, attorney, or 
consultant of the REINSURED or the REINSURER or either's affiliates.

The REINSURED and the REINSURER shall each name five (5) candidates to serve 
as an arbitrator.  The REINSURED and the REINSURER shall each choose one 
candidate from the other party's list, and these two candidates shall serve 
as the first two arbitrators.  If one or more candidates so chosen shall 
decline to serve as an arbitrator, the party which named such candidate shall 
add an additional candidate to its list, and the other party shall again 
choose one candidate from the list.  This process shall continue until two 
arbitrators have been chosen and have accepted.  The REINSURED and the 
REINSURER shall each present their initial lists of five (5) candidates by 
written notification to the other party within twenty-five (25) days of the 
date of the mailing of the notification initiating the arbitration.  Any 
subsequent additions to the list which are required shall be presented within 
ten (10) days of the date the naming party receives notice that a candidate 
that has been chosen declines to serve.

The two arbitrators shall then select the third arbitrator from the eight (8) 
candidates remaining on the lists of the REINSURED and the REINSURER within 
fourteen (14) days of the acceptance of their positions as arbitrators. If 
the two arbitrators cannot agree on the choice of a third, then this choice 
shall be referred back to the REINSURED and the REINSURER. The REINSURED and 
the REINSURER shall take turns striking the name of one of the remaining 
candidates from the initial eight (8) 


                                      32
<PAGE>

candidates until only one candidate remains. If the candidate so chosen shall 
decline to serve as the third arbitrator, the candidate whose name was 
stricken last shall be nominated as the third arbitrator. This process shall 
continue until a candidate has been chosen and has accepted. This candidate 
shall serve as the third arbitrator. The first turn at striking the name of a 
candidate shall belong to the party that is responding to the other party's 
initiation of the arbitration. Once chosen, the arbitrators are empowered to 
decide all substantive and procedural issues by a majority of votes.

It is agreed that each of the three arbitrators should be impartial regarding
the dispute and should resolve the dispute on the basis described in the
"ARBITRATION" section of this Agreement. Therefore, at no time will either the
REINSURED or the REINSURER contact or otherwise communicate with any person who
is to be or has been designated as a candidate to serve as an arbitrator
concerning the dispute, except upon the basis of jointly drafted communications
provided by both the REINSURED and the REINSURER to inform those candidates
actually chosen as arbitrators of the nature and facts of the dispute. 
Likewise, any written or oral arguments provided to the arbitrators concerning
the dispute shall be coordinated with the other party and shall be provided
simultaneously to the other party or shall take place in the presence of the
other party. Further, at no time shall any arbitrator be informed that the
arbitrator has been named or chosen by one party or the other.

The arbitration shall be held on the date fixed by the arbitrators. In no 
event shall this date be later than six (6) months after the appointment of 
the third arbitrator. As soon as possible, the arbitrators shall establish 
prearbitration procedures as warranted by the facts and issues of the 
particular case. In establishing such procedures the arbitrators shall make 
provision for reasonable pre-hearing examinations of officers, employees or 
agents of the parties and for the production of relevant documentation. At 
least ten (10) days prior to the arbitration hearing, each party shall 
provide the other party and the arbitrators with a detailed statement of the 
facts and arguments it will present at the arbitration hearing. The 
arbitrators may consider any relevant evidence; they shall give the evidence 
such weight as they deem it entitled to after consideration of any 


                                      33
<PAGE>

objections raised concerning it. The party initiating the arbitration shall 
have the burden of proving its case by a preponderance of the evidence. Each 
party shall be entitled to call as witnesses any officers, employees or 
agents of the other party and such other party shall do everything reasonable 
to ensure the attendance and cooperation of any such witnesses. Each party 
may examine any witnesses who testify at the arbitration hearing. Within 
twenty (20) days after the end of the arbitration hearing, the arbitrators 
shall issue a written decision that sets forth their findings and any award 
to be paid as a result of the arbitration, except that the arbitrators may 
not award punitive or exemplary damages. In their decision, the arbitrators 
shall also apportion the costs of arbitration, which shall include, but not 
be limited to, their own fees and expenses.

    year.

6.  The REINSURER may contest such calculation by providing an alternative
    calculation to the REINSURED in writing within 30 days of the REINSURER's
    receipt of the REINSURED's calculation.  If the REINSURER does not so
    notify the REINSURED, the REINSURER will report the net consideration as
    determined by the

    REINSURED in the REINSURER'S tax return for the previous calendar year.

7.  If the REINSURER contests the REINSURED's calculation of the net
    consideration, the parties will act in good faith to reach an agreement as
    to the correct amount within thirty (30) days of the date the REINSURER
    submits its alternative calculation.  If the REINSURED and the REINSURER
    reach agreement on an amount of net consideration, each party shall report
    such amount in their respective tax returns for the previous calendar year.

<PAGE>

AmVestors; and

         WHEREAS, as of the Effective Date (as defined in Section 3 hereof)
AmVestors shall have been acquired by ALH as described in that certain Agreement
and Plan of Merger dated September 19th, 1997 (hereinafter referred to as
"Merger Agreement");

         WHEREAS, ALH desires for the Company to continue to have the benefit 
of Mr. Heitz's knowledge and experience and considers such a vital element in 
protecting and enhancing the best interests of ALH and its shareholders and 
in providing management for AmVestors.

         NOW, THEREFORE, in consideration of the mutual agreements and
conditions contained herein, the parties hereto agree as follows:

         1.   FULL-TIME EMPLOYMENT OF EXECUTIVE.

              a.   DUTIES AND STATUS.

                   (1)  AmVestors hereby employs Mr. Heitz as its President and
Chief Executive Officer and American hereby employs Mr. Heitz as its President
and Chief Executive Officer to provide certain services set forth herein and to
provide certain other employment services to affiliates for the employment
period as defined in paragraph 3(a), and Mr. Heitz accepts such employment, on
the terms and conditions set forth in this Agreement.  During the employment
period, Mr. 



                                   2
<PAGE>

Heitz shall perform such managerial duties and responsibilities for
AmVestors and affiliates as may be assigned to him in accordance with the
bylaws.

                   (2)  During the employment period, Mr. Heitz shall devote 
his full time and efforts to the business of AmVestors and its affiliates and 
shall not engage in consulting work or any trade or business for his own 
account or for or on behalf of any other person, firm or corporation which 
competes, conflicts or interferes with the performance of his duties 
hereunder in any way. Mr. Heitz shall be entitled to reasonable vacations and 
to such personal and sick leave as may be established by AmVestors' and 
affiliates corporate policies.  Mr. Heitz shall perform his duties while 
employed in good faith and shall observe faithfully the covenants and 
agreements made by him herein.

              b.   COMPENSATION AND GENERAL BENEFITS.

                   (1)  During the employment period, AmVestors shall pay Mr.
Heitz a base salary to be established annually by the Board of Directors,
payable in twice monthly installments (or on such other basis as may be mutually
agreed upon).  The salary shall be reviewed annually by the Board of Directors
and may be increased, but not diminished, during the employment period.

                   (2)  In addition to the salary provided by subparagraph (1)
of this paragraph 1(b), AmVestors and affiliates shall provide benefits and
other perquisites reasonably comparable to, and no less favorable than, those



                                  3
<PAGE>

provided by AmVestors and its affiliates to Mr. Heitz during 1997, including,
but not limited to, an automobile suitable for the business and personal use of
Mr. Heitz.

                   (3)  Attached hereto is a copy of a letter from ALH setting
forth the compensation and general benefits to be payable to Mr. Heitz during
the employment period.  ALH guarantees performance by the Company of its
obligations under this paragraph 1(b) throughout the entire term of this
Agreement.

         2.   COMPETITION:  CONFIDENTIAL INFORMATION.

         The parties recognize that, due to the nature of Mr. Heitz's prior
association with the Companies and of his engagement hereunder, and as a
consequence of his relationship to Companies, both in the past and in the
future, Mr. Heitz has had access to and has acquired, and has assisted in and
may assist in developing confidential and proprietary information relating to
the business and operations of the Companies.  Mr. Heitz recognizes that such
information has been and will continue to be of central importance to the
business of the Companies and that disclosure of such information to others or
its use by others could cause substantial irreparable loss to the Companies. 
Mr. Heitz and Companies also recognize that an important part of Mr. Heitz's
duties will be to develop good will for the Companies through his personal
contact with others having business relationships with Companies and within the
insurance industry, and that there is a danger that this good will, a
propri-



                                 4
<PAGE>

etary asset of the Companies, may follow him if and when his relationship
with the Companies is terminated.  Mr. Heitz accordingly agrees as follows:

              a.   NON-COMPETITION DURING EMPLOYMENT PERIOD.  During the
employment period he will not directly or indirectly, either individually or as
owner, partner, agent, employee, consultant or otherwise, except for the account
of and on behalf of Companies, engage in any activity competitive with the
business of Companies, nor will he be in competition with Companies, solicit or
otherwise attempt to establish any business relationships with any person, firm
or corporation which was, at any time during the employment period, a customer
or supplier of Companies.  However, nothing in this Section 2 shall be construed
to prevent him from owning, as an investment, up to one percent (1%) of a class
of equity securities issued by any competitor of Companies.

              b.   NON-COMPETITION AFTER PERIOD OF EMPLOYMENT.  Mr. Heitz
agrees that during the term of this Agreement and for a period of two years
following termination of this Agreement, if payments are being made to Mr. Heitz
pursuant to paragraph 3.c., he will not, without the Companies prior written
permission, attempt to entice away from the Companies or affiliates or
subsidiaries on behalf of any party whatsoever, or employ or otherwise engage,
contract with or retain directly or indirectly; (i) any employee then employed
by the Companies, affiliates or subsidiaries or employed by them at any time
during the previous two (2) 



                                      5
<PAGE>

years; or (ii) any individual or entity under engagement by the Companies 
during the previous two yeas, by contract or otherwise, for the purpose of 
marketing, distributing or selling insurance and annuity products or 
developing clients or customers on behalf of the Companies. Mr. Heitz further 
agrees that during such period (if such payments are being made), he will not 
do anything to impair the Companies or their affiliates or subsidiaries' 
prospects of sales or business retention, and shall not solicit for any 
reason any of the Companies or its employees, agency personnel, insureds or 
applicants, nor knowingly accept commissions directly or indirectly on any 
policy written in replacement of any policy produced or written by the 
Companies or any of their affiliates or subsidiaries nor shall Mr. Heitz in 
any way derogate the Companies, its products or personnel.

              c.   CONFIDENTIAL INFORMATION.  Mr. Heitz will not disclose any
confidential information of Companies which is now known to him or which
hereafter may become known to him as a result of his employment or association
with Companies and shall not at any time directly or indirectly disclose any
such information to any person, firm or corporation, or use the same in any way
other than in connection with the business of Companies and at all times after
the expiration of the employment period.

              d.   COMPANIES' REMEDIES FOR BREACH.  It is recognized that
damages in the event of breach of this Section 2 by Mr. Heitz would be
difficult, if 



                                      6
<PAGE>

not impossible, to ascertain and it is, therefore, agreed that each of the 
Companies, in addition to and without limiting any other remedy or right it 
may have, shall have the right to an injunction or other equitable relief in 
any court of competent jurisdiction, enjoining any such breach, and Mr. Heitz 
hereby waives any and all defenses he may have on the ground of lack of 
jurisdiction or competence of the court to grant such an injunction or other 
equitable relief.  The existence of this right shall not preclude Companies 
from pursuing any other rights and remedies at law or in equity which 
Companies may have.

         3.   EMPLOYMENT PERIOD.

              a.   DURATION.  The employment period shall commence on the date
of the closing of the acquisition of AmVestors as described in the Merger
Agreement (the "Effective Date") and shall end on December 31, 2000 unless
otherwise terminated as provided in this Agreement.

              b.   PERFORMANCE AND TERMINATION.  Subject to the performance of
the covenants and agreements made by Companies herein, Mr. Heitz shall perform
his duties during the employment period in good faith and will observe
faithfully the covenants and agreements made by him herein.  Mr. Heitz shall not
be discharged during the employment period except for cause involving
dishonestly, moral turpitude, or material breach of any express or implied
condition under this 



                                      7
<PAGE>

Agreement.  The discharge of Mr. Heitz for reasons other than those specified 
in the preceding sentence shall be deemed to be a discharge without cause.

              c.   MR. HEITZ'S REMEDIES.  If the Companies shall take any
action with respect to Mr. Heitz's employment as set forth in paragraph 3(d)
thereby entitling him to terminate his employment as provided in paragraph 3(d),
or discharges him without cause then Mr. Heitz shall be entitled to be paid a
sum equal to two (2) years salary based on the base salary level in effect on
the date of termination or discharge.  Payments shall be made bimonthly in 48
equal installments and shall commence on the effective date of discharge or
termination.  The parties agree that, the payments provided hereunder shall be
deemed to constitute payment for the non-compete provisions contained in
paragraph 2(b) and not a penalty for breach by Companies and Companies agree
that Mr. Heitz shall not be required to mitigate his damages.  This paragraph
shall constitute Mr. Heitz's sole remedy for compensation upon the cessation of
his employment and/or breach of this Agreement.

         In the event Mr. Heitz materially violates the non-compete provisions
of paragraph 2(b) after his employment has ceased then Companies shall have the
right to cease all payments required under the provisions of paragraph 3(c).

              d.   TERMINATION FOR GOOD REASON.  Mr. Heitz shall be entitled to
terminate his employment for good reason.  Any termination of employ-



                                      8
<PAGE>

ment under the following circumstances shall be for good reason and shall be 
deemed to be a breach of this Agreement by the Companies:

                   (1)  Without the express written consent of Mr. Heitz, he is
assigned any duties inconsistent with his positions, duties, responsibilities
and status with the Companies since the Effective Date, or his reporting
responsibilities, titles or offices as in effect during the period of this
Agreement are changed or he is removed from or not reelected to any of such
positions, except in connection with the termination of his employment for
cause, or as a result of his substantial disability or death;

                   (2)  The annual base salary of Mr. Heitz as in effect on the
