ITEM 1.  BUSINESS

GENERAL

     AmerUs Life Holdings, Inc. (the Company) 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, the District of Columbia and the U.S.
Virgin Islands. The Company was formed in 1996 as a result of the creation of
the first mutual insurance holding company in the United States, the American
Mutual Holding Company (AMHC). AMHC owns approximately 58% of the Company. The
Company's principal subsidiaries are AmerUs Life Insurance Company (AmerUs
Life), Delta Life Corporation (Delta) and AmVestors Financial Corporation
(AmVestors).

     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 American Mutual Life Insurance Company into Central Life Assurance
Company. On June 30, 1996, American Mutual Life Insurance Company was converted
into a stock life insurance company pursuant to a plan of reorganization
involving the formation of AMHC (the Reorganization) and its name was changed to
AmerUs Life. AmerUs Life is licensed to do business in the District of Columbia
and in all states except New Hampshire and New York.

     On October 23, 1997, the Company acquired all of the outstanding capital
stock of Delta for approximately $165 million in cash (the Delta Acquisition).
The principal asset of Delta is its wholly-owned subsidiary, Delta Life and
Annuity Company (Delta Life), an Iowa domiciled life insurance company formed in
1955 that is licensed in the District of Columbia and in all states except New
York.

     On December 19, 1997, the Company acquired AmVestors in a stock exchange
valued at approximately $350 million (the AmVestors Acquisition). AmVestors'
principal operating subsidiaries are American Investors Life Insurance Company,
Inc. (American), a Kansas domiciled life insurance company licensed in 49 states
and the District of Columbia; and Financial Benefit Life Insurance Company
(FBL), a Kansas domiciled life insurance company doing business in 43 states,
the District of Columbia and the U.S. Virgin Islands.

     The Company also participates in a joint venture with Ameritas Life
Insurance Corp. (Ameritas) (Ameritas Joint Venture) through AmerUs Life's 34%
ownership interest in AMAL Corporation, a Nebraska corporation (AMAL). AMAL's
operations are conducted through Ameritas Variable Life Insurance Company
(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 47 states and the District of Columbia. AIC is a
registered broker-dealer which is licensed to do business in all states except
New York. AmerUs Life's partner in the Ameritas Joint Venture, Ameritas, is a
Nebraska mutual life insurance company which has been in existence for more than
100 years.

     On December 20, 1999, the Company and the Company's controlling
shareholder, AMHC, announced that their respective boards of directors had
approved plans for the demutualization of AMHC and the merger of the Company
into AMHC following the demutualization. Upon completion of the demutualization,
AMHC would be a public company. AMHC will change its name to AmerUs Group Co.
(AmerUs Group) and be traded on the New York Stock Exchange under the symbol
"AMH". Members of AMHC will receive approximately 17 million shares of AmerUs
Group and cash or policy credits in excess of $300 million as a result of the
demutualization. Shareholders of the Company will receive shares in AmerUs Group
in a one-for-one exchange. To complete the demutualization and merger, approval
is needed from the members of AMHC, the Iowa Commissioner of Insurance and
shareholders of the Company. Members of AMHC and shareholders of the Company
will be asked to approve the proposed demutualization and merger plans during
the second quarter of 2000.

     On February 18, 2000, the Company, AMHC and Indianapolis Life Insurance Co.
(ILICO) entered into a definitive agreement for a combination of the companies.
Under these terms, AMHC will proceed with its previously announced
demutualization. ILICO will demutualize separately and ILICO's members will
receive cash, policy credits and stock equivalent to the value of 11.25 million
shares of stock of AmerUs Group. Upon demutualization, ILICO will become a
subsidiary of AmerUs Group and will continue operations as a stock life
insurance company. As part of the transaction, AMHC made an initial investment
of $100 million in a downstream holding company of ILICO on February 18, 2000.
ILICO is a 95-year old mutual life insurance and annuity company based in
Indianapolis, Indiana. ILICO and its subsidiaries are licensed to do business in
all 50 states and the District of Columbia. At December 31, 1999, ILICO had
total assets of $6.1 billion and insurance in force of $30.3 billion. The
contemplated transactions are subject to normal closing conditions, including
appropriate policyholder/member, shareholder and regulatory approvals. The
Company expects the demutualization of ILICO and combination with AmerUs Group
to take place in the fourth quarter of 2000.

OPERATIONS

     The Company has two operating segments: Life Insurance and Annuities.

     Additional information concerning the Company's segments may be found in

</TABLE>

     Traditional Life Insurance Products.  The Company's traditional life
insurance products have a long history of being highly competitive within the
industry. 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. The Company
also offers a second to die whole life insurance product which insures two lives
and provides benefits upon the death of the second insured. The Company targets
its second to die products primarily to potential customers seeking to achieve
estate planning goals. Sales of participating whole life insurance decreased in
1999, which was consistent with the general industry decline of sales of this
product.

     Term life insurance provides 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. Term life insurance
is a highly competitive and quickly changing market. Term life insurance sales
increased

                                        3
<PAGE>   6

approximately 15% in 1999 primarily as a result of product repricing completed
in mid-1999 along with an increase in consumer demand for the product. Consumer
demand for term products was generally up in 1999 as a result of legislative
changes taking effect in January, 2000 which were anticipated to impact product
pricing. The increase in 1998 term life insurance sales was primarily due to the
introduction of three new term products in the first quarter of 1998.

     Since 1989, the Company 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. 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 year ended December 31, 1999, sales of participating whole life and
term life insurance products represented 43% and 19%, respectively, of first
year annualized premiums for all individual life insurance products sold by the
Company.

     Universal Life Insurance Products.  The Company 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 the
Company. Specific charges are made against the account for the cost of insurance
and for expenses. The universal life policy provides flexibility as to the
amount and timing of premium payments and the level of death benefits provided.

     The Company's universal life insurance products provide benefits for the
life of the insured. Within limits established by the Company 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. Increased sales of universal life in
1999, 1998 and 1997 were primarily attributable to new universal life products
introduced in each year. The weighted average crediting rate for universal life
insurance liabilities was 5.67% for the year 1999, 6.08% for the year 1998 and
6.23% for the year 1997. For the year ended December 31, 1999, sales of
universal life insurance products represented 38% of first year annualized
premiums for all individual life insurance products sold by the Company.

     The following table sets forth the Company's collected individual life
premiums, including collected individual life premiums associated with the
Closed Block, for the periods indicated:

DISTRIBUTION SYSTEMS

     The Company sells life insurance in 49 states, the District of Columbia and
the U.S. Virgin Islands. The states with the highest geographic concentration of
sales, based on statutory premiums, are California, Iowa, Minnesota, Texas and
Illinois. These states account for approximately 44% of the Company's statutory
premiums.

     The Company's target customers are individuals in the middle and upper
income brackets and small businesses. The Company markets its life insurance
products on a national basis primarily through a Preferred Producer agency
system and a Personal Producing General Agent (PPGA) distribution system. The
Company currently employs 14 regional vice presidents who are responsible for
supervising the Preferred Producer agencies and/or PPGA agents within their
assigned geographic regions.

     Under the Preferred Producer agency system, a contractual arrangement is
entered into with the Preferred Producer general agent for the sale of insurance
products by the Preferred Producer agents and brokers assigned to the Preferred
Producer general agent's agency. The Preferred Producer general agents are
primarily compensated by receiving a percentage of the first year commissions
paid to Preferred Producer agents and brokers in the Preferred Producer general
agent's agency and by renewal commissions on premiums subsequently collected on
that business. In addition, the Preferred Producers receive certain fringe
benefits and other allowances.

     The Preferred Producer 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 Preferred Producer agents and brokers in their
agency. Currently, the Company has 40 Preferred Producer general agents in 23
states, through which approximately 750 Preferred Producer agents sell the
Company's products. While Preferred Producer agents in the Preferred Producer
agency system are non-exclusive, most agents use the Company's products for a
majority of their new business of the type of products offered by the Company.
No single Preferred Producer general agency accounts for more than 7% of the
total first year life commissions paid by the Company.

     Preferred Producer agents are also independent contractors and are
primarily compensated by commissions on first year and renewal premiums
collected on business written by them plus certain fringe benefits and other
allowances. In addition, Preferred Producer agents can earn bonus commissions,
graded by production and persistency on their business.

                                        5
<PAGE>   8

     Under the PPGA system, the Company 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 the Company
rather than the Company's full line of insurance products. The PPGA system is
comprised of approximately 900 PPGA's, with approximately 1,100 agents.

     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.

     The Company has also developed programs to sell life insurance through
select banks and brokerages. The customers targeted and the products sold are
similar to those of the Preferred Producer agency system and the PPGA system,
with an emphasis on wealth distribution and deferred compensation products in
the bank channel and an emphasis on universal life products in the brokerage
channel.

     Under the bank distribution system, the Company contracts with banks and
marketing organizations for the sale of insurance products by agents who are
employees of the banks. Commissions are paid to the banks. Currently, the
Company has approximately 23 banks and 3 marketing organizations under contract
through which approximately 240 agents sell the Company's products. The Company
provides training and servicing support to the banks and marketing
organizations.

     Under the brokerage distribution system, a contractual arrangement is
entered into with an independent brokerage general agent to promote the
Company's insurance products to their network of agents and brokers. The agent
receives a commission and the general agent receives an override commission on
the business produced. The Company currently has 19 brokerage general agents
under contract.

ANNUITY SEGMENT

PRODUCTS

     The Company's annuity premiums consisted of approximately 89% from fixed
annuity products and 11% from equity-index annuity products in 1999. Annuity
premiums increased significantly in 1998 due to the Company's acquisition of
Delta and AmVestors in the fourth quarter of 1997. The following table sets
forth annuity collected premiums for the periods indicated:

     Fixed Annuity Products.  The Company offers a broad portfolio of fixed
annuity products. Annuities provide for the payment of periodic benefits over 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.

     The Company offers a variety of interest rate crediting strategies on its
fixed annuity products. These strategies include initial interest crediting
rates with guarantees for periods of one to five years. Following the initial
guarantee period, the Company may adjust the credited interest rate annually,
subject to the minimum interest rates specified in the contracts. Such minimum
guarantee rates currently range from 3% to 5%. The

                                        6
<PAGE>   9

Company also offers an interest rate crediting strategy that credits the policy
with a return generally based upon the interest rates it earns on assets
supporting the respective policies less management fees.

     Equity-Index Annuities.  The Company offers equity-index annuity products
that are based on Standard & Poor's 500 Composite Stock Price
Index -- Registered Trademark. Earnings credited to these products generally are
linked to increases in the anniversary date values of the applicable index, less
management fees.

     In the third quarter of 1999, the Company entered into a reinsurance
agreement for the assumption of a block of equity-index annuities totaling $59.6
million from its joint venture partner, AVLIC. In conjunction with this
transaction, the Company now directly issues this equity-index product, which
contributed to the increased sales in 1999. In addition, the Company introduced
a new equity-linked product in mid-1999 which had a positive impact on sales.

     In December 1999, the Company introduced a multi-choice annuity product
which provides for various earnings strategies under one product, such as a
long-term equity index, an annual equity index, an investment grade bond index,
and a guaranteed one-year rate. Earnings are credited to this product based on
the increases in the applicable indexes, less management fees, and funds may be
moved between investment alternatives.

each date presented:

DISTRIBUTION SYSTEMS

     The Company sells annuities in 49 states, the District of Columbia and the
U.S. Virgin Islands. The states with the highest geographic concentration of
sales, based on statutory premiums, are Iowa, California, Illinois, Florida and
Texas. These states account for approximately 54% of the Company's statutory
premiums.

     The Company directs its marketing efforts towards the asset accumulation,
conservative savings, and retirement markets. The Company markets its annuity
products on a national basis primarily through networks of independent agents.
The independent agents are supervised by regional vice presidents and regional
directors or Independent Marketing Organizations (IMOs). In addition, the
Preferred Producer Agency and PPGA systems discussed previously are utilized to
market select annuity products.

     The regional vice presidents and regional directors are primarily
responsible for recruiting agents and servicing those agents in an effort to
promote the Company's products. The regional vice presidents' and regional
directors' marketing support activities include informational mailings,
seminars, and case consultations, all of which are designed to educate agents
about annuities in general and the Company in particular. Regional vice
presidents and regional directors are paid a base salary plus incentive
compensation based on the business produced by agents within their territory.
There are currently four regional vice presidents and regional directors
covering the southeastern, western, southwestern and midwestern regions of the
United States.

     The Company's IMOs consist of approximately 70 contracted organizations,
two wholly-owned organizations and one partially-owned organization. The IMOs
are responsible for recruiting, servicing and educating

                                        7
<PAGE>   10

agents in an effort to promote the Company's products. The IMOs receive an
override commission based on the business produced by their agents.

     The Company currently has approximately 8,300 independent agents licensed
to sell its products. The Company also maintains contact with approximately
56,000 agents that are not currently licensed, but have either sold the
Company's annuities in the past or have expressed an interest in doing so. These
agents continue to receive periodic mailings related to interest rate and
commission changes, and new product introductions, and are reappointed as
required in order to represent the Company in selling its products. However, in
order to save costs associated with reappointing agents, the Company does not
automatically relicense an agent that has not written business for twelve
months.

     No single agent accounted for more than 0.9% of the Company's annuity sales
in 1999. The Company does not have exclusive agency agreements with its agents
and management believes most of these agents sell products similar to those sold
by the Company for other insurance companies.

     The Company also sells annuities through the bank channel discussed
previously in the Life Insurance Segment section. The customers targeted and the
products sold are similar to those sold by the independent agent networks.
Subsequent to year end, the Company purchased an 80% ownership interest in an
independent marketing organization that is associated with over 700 community
banks in the southeast region of the United States. Fixed annuity products are
the primary product focus of this organization.

AMERITAS JOINT VENTURE

     The Company's investment in the Ameritas Joint Venture affords the Company
access to a line of existing variable life insurance and annuity products while
providing a lower-cost entry into an established business, thereby eliminating
significant start-up costs and allowing for immediate potential earnings.

     The Ameritas Joint Venture offers through AVLIC fixed annuity products,
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, owners of variable annuities
and life insurance policies are able to choose from a range of investment funds
offered by each manager.

     Under the terms of the joint venture agreement, AmerUs Life and Ameritas
write their new single and flexible premium deferred fixed annuities and
variable annuities and variable life insurance through the Ameritas Joint
Venture. AmerUs Life 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. AmerUs Life also offers equity-index annuity
products directly.

     The variable life insurance products and the fixed and variable annuities
offered by the Ameritas Joint Venture are distributed through the Company's
Preferred Producer general agency, PPGA, and Bank distribution systems, as well
as through the distribution systems of Ameritas and AVLIC.

     Under the terms of the joint venture agreement, AmerUs Life has an option
to purchase an additional 5% to 15% of AMAL if certain premium growth targets
are met. AmerUs Life and Ameritas each have guaranteed the policyholder
obligations of AVLIC. The guarantee of each party is joint and several, and will
remain in effect until certain conditions are met.

     As of December 31, 1999, AMAL had total consolidated assets of $2,756.0
million and total consolidated shareholder's equity of $86.8 million on a GAAP
basis. AVLIC had $5.4 billion of insurance in force and $41.6 million in surplus
as of December 31, 1999, on a statutory basis.

COMPETITION

     The Company operates in a highly competitive industry. Numerous life
insurance companies and other entities, including banks and other financial
institutions, compete with the Company, many of which have greater financial and
other resources as compared to the Company. The Company believes that the
principal competitive factors in the sale of insurance products are product
features, price, commission structure,
                                        8
<PAGE>   11

perceived stability of the insurer, financial strength ratings, value-added
service and name recognition. Many other companies are capable of competing for
sales in the Company's target markets (including companies that do not presently
compete in such markets). The Company's ability to compete for sales is
dependent upon its ability to address the competitive factors described above.

     In addition to competing for sales, the Company 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 the Company 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.

     As of December 31, 1999, AmerUs Life's financial strength rating was: rated
"A" (Excellent) by A.M. Best Company; rated "Baa1" (Adequate) by Moody's
Investors Service; and rated "A" (Strong) by Standard & Poor's.

     Delta Life's financial strength rating was: rated "A" (Excellent) by A.M.
Best Company; rated "Baa1" (Adequate) by Moody's Investors Service; and rated
"BBB" (Good) by Standard & Poor's.

     American's financial strength rating was: rated "A-" (Excellent) by A.M.
Best Company; rated "Baa1" (Adequate) by Moody's Investors Service; and rated
"A" (Strong) by Standard & Poor's.

     FBL's financial strength rating was "B+" (Very Good) at A.M. Best Company
and "BBB" (Good) by Standard & Poor's.

INSURANCE UNDERWRITING

     The Company follows detailed, uniform underwriting practices and procedures
in its insurance business which are designed to assess risks before issuing
coverage to qualified applicants. The Company has professional underwriters who
evaluate policy applications on the basis of information provided by applicants
and others.

REINSURANCE

     In accordance with industry practices, the Company reinsures portions of
its life insurance and disability income exposure with unaffiliated insurance
companies under traditional indemnity reinsurance arrangements. Such reinsurance
arrangements are in accordance with standard reinsurance practices within the
industry. The Company enters into these arrangements to assist in diversifying
their risks and to limit the maximum loss on risks that exceed policy retention
limits. The Company's maximum retention limit for life insurance policies was
$1,000,000 per life insured. Effective January 1, 2000, the Company entered into
additional reinsurance agreements which effectively reduced the Company's
retention limit to $100,000 for the majority of policies issued since July 1,
1996 and for the majority of new business going forward. Indemnity reinsurance
does not fully discharge the Company's obligation to pay claims on business it
reinsures. The Company, as the ceding company, remains responsible for policy
claims to the extent the reinsurer fails to pay such claims. The Company
annually monitors the creditworthiness of its primary reinsurers, and has
experienced no material reinsurance recoverability problems in recent years.

     As of December 31, 1999, the Company had reinsurance arrangements in place
for life insurance having a face amount of approximately $5.6 billion with 19
unaffiliated reinsurers. All but one of the companies with which the Company had
life reinsurance arrangements as of such date were rated "A" or better by A.M.
Best. As of December 31, 1999, the Company's top five reinsurers (by face amount
reinsured) constituted approximately 87% of the total face amount reinsured by
the Company as of such date. Of these top five reinsurers, three are rated "A+"
and the other two "A" by A.M. Best.

     The Company reinsures 25% of its equity-index annuity reserves with an
unaffiliated reinsurer which is rated "A+" by A.M. Best. The Company also
reinsures approximately 1% of its deferred annuities with an unaffiliated
company which is rated "A" by A.M. Best.

EMPLOYEES

     As of December 31, 1999, the Company had 694 full-time employees. None of
these employees are covered by a collective bargaining agreement and the Company
believes that its relations with employees are satisfactory.

SUBSIDIARIES

     The Company was formed in August, 1996 in connection with the creation of
the first mutual insurance holding company in the United States. The Company has
primarily four wholly-owned subsidiaries: AmerUs Life, an Iowa life insurance
company; Delta, an Iowa corporation; AmVestors, a Kansas corporation and AmerUs
Capital Management Group, Inc. (ACM), an Iowa corporation. AmerUs Life has two
wholly-owned subsidiaries: CLA Assurance Company, an Iowa life insurance
company; and American Vanguard Life Insurance Company, an Iowa life insurance
company. In addition, AmerUs Life currently owns a 34% interest in AMAL
Corporation, through whose wholly-owned subsidiaries the Ameritas Joint Venture
operates. Delta primarily has one wholly-owned subsidiary, Delta Life, an Iowa
life insurance company. AmVestors primarily has two wholly-owned subsidiaries:
American, a Kansas life insurance company; and FBL, a Kansas life insurance
company. ACM has one wholly-owned subsidiary, ACM Properties, Inc.

REGULATION

     The Company is indirectly controlled by a mutual insurance holding company,
AMHC. Mutual insurance holding companies are subject to regulation by the Iowa
Insurance Division. This includes compliance with the Iowa Insurance Holding
Company Systems Act. The Iowa Commissioner of Insurance also has jurisdiction
over an intermediate holding company, such as the Company, as if it were a
mutual insurance holding company.

     AMHC and the Company are also each subject to the Iowa Insurer Supervision,
Rehabilitation and Liquidation Act, Iowa Code Chapter 507C. In addition, the
assets of AMHC and the Company are available to satisfy claims of AmerUs Life in
the event the Iowa Commissioner initiates a proceeding under Chapter 507C. AMHC
and the Company may not merge with or be acquired by another entity without
approval of the Iowa Commissioner. In addition, in the case of a merger of AMHC
with another mutual company, separate approval by the Iowa Attorney general is
required.

     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
a reorganization pursuant to Iowa law, the Iowa Commissioner has adopted rules
that limit the activities and affiliations that are permissible for a mutual
insurance holding company. The Iowa Commissioner also has issued rules which,
under certain circumstances, require prior approval by the Iowa Commissioner of
the issuance of stock by the Company.

     Shares of the capital stock of the Company which carry the right to cast a
majority of the votes entitled to be cast by all of the outstanding shares of
the Company 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.

     AmerUs Life, Delta Life, American and FBL 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 sales practices, 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 the Company's insurance companies are licensed
administers a guaranty fund, which provides for assessments of licensed insurers

companies. Assessments can be partially recovered through a reduction in future
premium taxes in some states.

     Risk-based capital ("RBC") standards for life insurance companies were
adopted by the National Association of Insurance Commissioners ("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 and Kansas. 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 December 31, 1999, AmerUs
Life's, Delta Life's, American's and FBL's RBC levels were 508%, 541%, 441% and
473%, respectively, of each of their respective authorized control level RBC
thresholds.

DIVIDENDS

     The Company's Board of Directors has declared and paid a quarterly dividend
of $0.10 per share of Common Stock, beginning in the second quarter of 1997. The
Board of Directors has approved moving from a quarterly dividend to an annual
dividend beginning in 2000. The declaration and payment of dividends in the
future is subject to the discretion of the Company's Board of Directors and will
be dependent upon the Company's financial condition, results of operations, cash
requirements, future prospects, regulatory restrictions on the payment of
dividends by the Company's life insurance subsidiaries and other factors deemed
relevant by the Company's Board of Directors.

     The Company is an insurance holding company whose principal assets consist
of all of the outstanding shares of the common stock of its life insurance
subsidiaries. The Company's ongoing ability to pay dividends to its shareholders
and meet its other obligations, including operating expenses and any debt
service, primarily depends upon the receipt of sufficient funds from its life
insurance subsidiaries in the form of dividends, interest payments or loans.

     Based on statutory insurance regulations and 1998 results, the Company's
subsidiaries could have paid an estimated $60.7 million in dividends in 1999
without obtaining regulatory approval. Of this amount, the Company's
subsidiaries paid the Company $48 million in dividends in 1999. Based on 1999
results, the

                                       12
<PAGE>   15

Company's subsidiaries can pay an estimated $61.1 million in dividends in 2000
without obtaining regulatory approval.

     Under its bank credit facility, the Company is prohibited from paying
dividends on its Common Stock in excess of an amount equal to 3% of the
Company's consolidated net worth as of the last day of the preceding fiscal
year.

     In connection with the 8.85% Capital Securities, Series A (the "Capital
Securities"), issued in 1997 by AmerUs Capital I, the Company's subsidiary
trust, and the 7.00% Adjustable Conversion-rate Equity Security Units (ACES),
issued in 1998 by AmerUs Capital II, the Company's subsidiary trust, the Company
has agreed not to declare or pay any dividends on the Company's capital stock
(including the Class A Common Stock) during any period for which the Company
elects to extend interest payments on its junior subordinated debentures, except
for stock dividends paid by the Company where the dividend stock is the same
stock as that on which the dividend is being paid. Dividends on the Company's
capital stock cannot be paid until all accrued interest on the Capital
Securities and ACES has been paid.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION

     The following analysis of the consolidated results of operations and
financial condition of the Company should be read in conjunction with the
Selected Consolidated Financial and Operating Data and Consolidated Financial
Statements and related notes.

OVERVIEW

     The Company 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,
the District of Columbia and the U.S. Virgin Islands. The Company has two
reportable operating segments: Life Insurance and Annuities. The Life Insurance
segment's primary product offerings consist of whole life, universal life and
term life insurance policies. The primary product offerings of the Annuity
segment are fixed annuities.

     In accordance with Generally Accepted Accounting Principals (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. The Company 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 deferred. The
method of amortizing deferred policy acquisition costs for life insurance
products varies, 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 statutory surplus. Non-participating life insurance deferred policy
acquisition costs are 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. Deferred acquisition costs for participating
policies are amortized as an expense primarily 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
the Company 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. The Company has the ability to mitigate adverse experience through
adjustments to credited interest rates, policyowner dividends or cost of
insurance charges.

ADJUSTED NET OPERATING INCOME

     The following table reflects net income adjusted to eliminate certain items
(net of applicable income taxes) which management believes do not necessarily
indicate overall operating trends. For example, net realized capital gains or
losses on investments, excluding gains or losses on convertible debt which are
considered core earnings, are eliminated. Net realized capital gains or losses
on investments may be realized at the sole discretion of management and are
often realized in accordance with tax planning strategies. Therefore, net
realized capital gains or losses do not reflect the Company's ongoing earnings
capacity. Different items are likely to occur in each period presented and
others may have different opinions as to which items may warrant adjustment.
Adjusted net operating income is the basis used by the Company in assessing
overall performance. Adjusted net operating income as described here may not be
comparable to similarly titled measures reported by other companies. The
adjusted operating income shown below does not constitute net income computed in
accordance with GAAP.

(A) Represents total realized gains or losses (core and non-core) on investments
    adjusted for income taxes on such amounts. Realized gains or losses 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 gains on the convertible preferred stock and bond portfolio, net
    of income taxes. Such amounts are included in the total realized gains or
    losses adjustment in footnote (A). As these gains or losses are reflective
    of the Company's operating activities, they are added back to net income.

(C) Represents amortization of deferred policy acquisition costs due to non-core
    realized gains or losses being included in product margins adjusted for
    income taxes on such amounts.

(D) Represents costs in 1999 directly related to the Company's proposed merger
    with its controlling shareholder, AMHC, following the proposed
    demutualization of AMHC. These costs consist primarily of legal and
    consulting expenses. See further discussion of the proposed reorganization
    plans in Item 1. The 1996 and 1995 costs were directly related to the
    conversion of AmerUs Life into a stock company and consisted primarily of
    printing, postage, legal and consulting costs. These costs each year were
    not of a continuing nature and were not expected to have any effect on
    future operations.

                                       16

(E) Represents the mutual life insurance company equity add-on tax, which is
    applicable only to mutual life insurance companies and which is not
    applicable to the Company after June 30, 1996, due to AmerUs Life's
    conversion into a stock company.

(F) Basic adjusted operating income per common share for 1999, 1998 and 1997 is
    calculated using 30.23 million, 33.46 million and 23.54 million shares,
    respectively. Basic adjusted operating income per common share for 1996 and
    1995 is calculated using 23.16 million shares.

(G) Diluted adjusted operating income per common share for 1999, 1998 and 1997
    is calculated using 30.31 million, 33.70 million and 23.57 million shares,
    respectively. Diluted adjusted operating income per common share for 1996
    and 1995 is calculated using 23.16 million shares.

ACQUISITIONS

     The Company acquired all of the outstanding stock of Delta on October 23,
1997, for approximately $165 million in cash. The transaction was accounted for
as a purchase and accordingly, the Company's results of operations include Delta
from the date of purchase. The Company acquired all of the outstanding stock of
AmVestors on December 19, 1997, in a stock exchange valued at approximately $350
million. This transaction was also accounted for as a purchase and the Company's
results of operations include AmVestors from the date of purchase. (See Note 15
of the Consolidated Financial Statements for the discussion of the Company's
acquisitions.)

THE CLOSED BLOCK

     The Closed Block was established on June 30, 1996. 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 reorganization of AmerUs
Life, assets would be available to maintain the dividend scales and interest
credits in effect prior to the Reorganization if the experience underlying such
scales and credits continues.

     The contribution to the operating income of the Company 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 "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 titled
"Closed Block Assets". Likewise, all liabilities attributable to the Closed
Block are combined and disclosed as the "Closed Block Liabilities".

OPERATING SEGMENTS

     The Company has two reportable operating segments: Life Insurance and
Annuities. Products generally distinguish a segment. The Company uses the same
accounting policies and procedures to measure operating segment income as it
uses to measure its consolidated income from operations with the exception of
the elimination of certain items which management believes are not necessarily
indicative of overall operating trends. These items are explained further in the
Adjusted Net Operating Income section of Management's Discussion and Analysis of
Results of Operations and Financial Condition. Revenues and benefits and
expenses are primarily attributed directly to each operating segment. Net
investment income and core realized gains (losses) on investments are allocated
based on the directly-related asset portfolios. Other revenues and expenses
which are deemed not to be associated with any specific reportable segment are
grouped together in the All Other category. These items primarily consist of
discontinued product lines such as group and health and holding company revenues
and expenses. The Company assesses the performance of its operating

                                       17

segments before interest expense, income taxes, and equity in earnings of its
unconsolidated subsidiary, AMAL.

     Traditional life insurance premiums increased by $13.0 million to $64.3
million in 1999 compared to $51.3 million in 1998 and $30.7 million in 1997. The
increase in traditional life insurance premiums was primarily the result of the
growth of the business since the formation of the Closed Block in June, 1996 and
continued favorable persistency.

     Immediate annuity and supplementary contract premiums were $25.1 million in
1999 compared to $29.6 million in 1998 and $17.2 million in 1997. The decrease
in premiums in 1999 was primarily due to decreased immediate annuity sales while
the increase in annuity and supplementary contract premiums in 1998 was
primarily due to the acquisitions of Delta and AmVestors. Without these
acquisitions, immediate annuity and supplementary contract premiums increased by
$2.5 million in 1998 due to increased immediate annuity sales.

     Universal life product charges increased by $0.6 million in 1999 to $46.8
million compared to $46.2 million in 1998 and $45.6 million in 1997. The
increase in product charges each year was primarily due to increased cost of
insurance charges as a result of the normal aging of the block of business,
partially offset by higher reinsurance costs.

     Annuity product charges increased by $1.0 million in 1999 to $27.8 million
compared to $26.8 million in 1998 and $1.7 million in 1997. Increased surrender
charges and expense loads on deferred annuities primarily contributed to the
increase in 1999 while the increase in 1998 was primarily due to the
acquisitions of Delta

                                       18
<PAGE>   21

and AmVestors. Annuity product charges for 1998 and 1997 included $23.5 million
and $0.7 million, respectively, from Delta and AmVestors.

     Total net investment income was $540.1 million in 1999 compared to $503.4
million in 1998 and $224.4 in 1997. The increase in 1999 net investment income
was primarily attributable to higher average invested assets (excluding market
value adjustments) and a higher effective yield compared to 1998. Average
invested assets (excluding market value adjustments) increased approximately
$343.7 million in 1999 compared to 1998 primarily due to the Company's increased
investment funds from two structured asset-backed commercial paper vehicles. See
further discussion of these vehicles in the Liquidity and Capital Resources
section. The increase in 1998 net investment income was primarily due to the
acquisitions of Delta and AmVestors. Net investment income in 1998 and 1997
included $322.0 million and $30.2 million, respectively, from Delta and
AmVestors. The effective yield of the entire portfolio in 1999 was 7.15%
compared to 6.98% in 1998 and 7.49% in 1997. Yields in 1998 were impacted by a
decline in value on hedge funds and long-term private partnership investments
resulting in lower net investment income in both the life insurance and annuity
segments in that year. The effective yield of the annuity portion of the
portfolio decreased 10 basis points to 6.68% in 1999 compared to 6.78% in 1998
and 7.24% in 1997. The decrease in the 1999 effective yield primarily resulted
from lower reinvestment rates throughout 1998 and the majority of 1999 compared
to the portfolio rate at the beginning of the prior year period.

     Realized gains on investments were $3.2 million in 1999 compared to
realized losses of $0.1 million and realized gains of $13.8 million in 1998 and
1997, respectively. The level of realized gains and losses will fluctuate from
period to period depending on the prevailing interest rate and economic
environment and the timing of the sale of investments.

     All other income primarily consists of structured finance fees from
affordable housing programs.

     The Contribution from the Closed Block was $25.2 million in 1999 compared
to $31.5 million in 1998 and $31.0 million in 1997. The following table sets
forth the operating results of the Closed Block for the years ended December 31,
1999, 1998 and 1997:

     Closed Block insurance premiums decreased by $8.8 million in 1999 to $189.4
million compared to $198.2 million in 1998 and $206.1 million in 1997. The
decrease in insurance premiums each year is consistent with the reduction of the
Closed Block's life insurance in force that is expected to continue over the
life of the Block. Similarly, the 1999 decrease in product charges or universal
life policies included in the Closed Block is primarily the result of the
reduction of such business in force.

                                       19
<PAGE>   22

     Net investment income for the Closed Block decreased by $7.7 million in
1999 to $108.1 million compared to $115.8 million in 1998 and $113.8 million in
1997. The decrease in 1999 was primarily attributable to lower effective yields,
partially offset by higher average invested assets (excluding market value
adjustments) while the increase in 1998 was primarily attributable to the growth
in average invested assets (excluding market value adjustments) resulting from
the reinvestment of investment earnings.

     Realized losses on investments of the Closed Block were $0.4 million in
1999 compared to realized gains of $10.3 million in 1998 and $0.7 million in
1997. The level of realized gains and losses will fluctuate from period to
period depending on the prevailing interest rate and economic environment and
the timing of the sale of investments.

     Closed Block policyowner benefits decreased by $7.3 million in 1999 to
$193.5 million compared to $200.8 million in 1998 and $206.6 million in 1997.
The decrease in policyowner benefits each year is primarily due to lower death
benefits and to the reduction of life reserves which is consistent with the
reduction of the Closed Block's life insurance in force that is expected over
the life of the Block.

     The amortization of deferred policy acquisition costs for the Closed Block
decreased by $6.0 million in 1999 to $20.3 million compared to $26.3 million in
1998 and $31.5 million in 1997. The decrease in the amortization of deferred
policy acquisition costs each year is consistent with the projected reduction in
the gross margins of the Closed Block as the life insurance in force declines.

     Closed Block dividends to policyowners decreased by $8.1 million to $66.3
million in 1999 compared to $74.4 million in 1998 and $59.6 million in 1997. The
decrease in 1999 was primarily due to the decrease in deferred dividends
resulting from lower realized gains while the increase in 1998 primarily
resulted from increased deferred dividends associated with the higher realized
gains that year.

     Total life insurance benefits increased by $12.8 million in 1999 to $104.2
million compared to $91.4 million in 1998 and $77.8 million in 1997. An increase
in life insurance benefits is expected as the traditional block of business
continues to grow and as the universal block of business ages. However, in the
last half of 1999 the Company experienced higher than expected death benefits.
The Company does not believe

                                       20
<PAGE>   23

that this is an indication of a change in long-term mortality trends but more of
a fluctuation which is not unusual from time to time. Partially offsetting the
increases in death benefits and higher policy reserves in 1999 was a reduction
in interest credited. Interest credited on universal policyowner account
balances decreased $3.9 million in 1999 to $30.4 million compared to $34.3
million in 1998 primarily due to a reduction in crediting rates. The weighted
average interest crediting rate on policyowner account balances for 1999 was
5.67% compared to 6.08% for 1998. Interest credited on universal policyowner
account balances in 1998 was $1.5 higher than 1997. The increase was primarily
due to higher account values, partially offset by lower interest crediting
rates. The weighted average interest crediting rate decreased 15 basis points to
6.08% for 1998 compared to 6.23% for 1997.

     Annuity benefits were $338.0 million in 1999 compared to $339.3 million in
1998 and $117.6 million in 1997. The decrease in 1999 was primarily attributable
to a lower weighted average crediting rate on annuity balances in 1999 compared
to 1998, partially offset by higher average liabilities. The weighted average
crediting rate on deferred annuity account balances was decreased 24 basis
points to 4.95% for 1999 compared to 5.19% for 1998 and 5.25% for 1997.
Crediting rates were decreased in response to the decrease in effective yields
on the annuity investment portfolio resulting in GAAP spreads widening 14 basis
points in 1999 as compared to 1998. Other annuity benefits increased in 1999 as
compared to 1998. Other annuity benefits in 1999 included approximately $13.1
million of interest expense on two insurance contracts issued to two commercial
paper conduits during the year. See further discussion of these conduits in the
Liquidity and Capital Resources section. Partially offsetting this increased
expense was a decrease in immediate annuity reserves and benefit payments on
immediate annuities, which corresponds with the reduction in immediate annuity
sales. The increase in annuity benefits in 1998 was primarily due to the
acquisitions of Delta and AmVestors.

     Total life insurance expenses were $70.6 million in 1999 compared to $64.7
million in 1998 and $54.9 million in 1997. Underwriting, acquisition and
insurance expenses increased each year, primarily due to costs related to the
Year 2000 Compliance Project and costs associated with the Company's enhancement
of its administration and distribution systems. Amortization of deferred policy
acquisition costs and value of

                                       21
<PAGE>   24

business acquired (VOBA) decreased $4.1 million in 1999 and increased $5.0
million in 1998. Deferred policy acquisition costs are generally amortized in
proportion to gross margins. In 1999, modifications were made to the dividend
scale of traditional products to coincide with the decline in investment yields,
resulting in increased estimated future gross margins. These modifications
primarily contributed to the decreased amortization in 1999. Lower death
benefits in 1998 on those policies for which deferred costs are amortized
contributed to higher gross margins in 1998, resulting in the increased
amortization that year.

     Total annuity expenses increased by $4.7 million in 1999 to $79.3 million
compared to $74.6 million in 1998 and $14.1 million in 1997. Underwriting,
acquisition and insurance expenses decreased $4.7 million in 1999 primarily due
to cost savings realized from the consolidation of acquired subsidiary
operations. Amortization of deferred policy acquisition costs and VOBA increased
$9.3 million in 1999. Gross margins increased due to higher interest spreads and
the reduced expenses, resulting in the increased amortization. The increase in
annuity expenses in 1998 was primarily attributable to the acquisitions of Delta
and AmVestors.

     All other expenses increased by $5.4 million in 1999 and decreased by $1.7
million in 1998. Expenses in 1998 were reduced by certain one-time benefits and
1999 expenses included the amortization of the debt issuance costs on the
capital securities and senior notes issued in mid-1998 and additional holding
company expenses primarily related to air transportation, conferences, incentive
compensation and corporate development programs. The 1997 other expenses
included a $1.3 million write-off of expenses related to a former bank credit
facility which was replaced by a new agreement in 1997.

     The 1999 reorganization costs consist of legal and consulting expenses
associated with the Company's proposed merger with its controlling shareholder,
AMHC, following the proposed demutualization of AMHC. See further discussion of
these proposed reorganization plans in Item 1. As these costs are not of a
continuing nature, they have been excluded from the operating segment amounts.

     Adjusted pre-tax operating income from Life Insurance operations increased
by $9.1 million in 1999 to $50.3 million compared to $41.2 million in 1998 and
$46.5 million in 1997. The increase in 1999 compared to 1998 was primarily due
to increased investment income and decreased deferred policy acquisition cost
amortization which was partially offset by a decreased contribution from the
Closed Block and increased costs related to the Year 2000 Compliance Project and
enhancement of the Company's administration and distribution systems. The
decrease in 1998 was primarily due to lower net investment income and increased
costs related to the Year 2000 Compliance Project and costs associated with the
Company's development of alternative distribution systems.

     Adjusted pre-tax operating income from Annuity operations increased by $4.6
million in 1999 to $88.7 million compared to $84.1 million in 1998 and $35.2
million in 1997. The increase in 1999 was primarily due to increased spreads
while the increase in 1998 was primarily due to the acquisitions of Delta and
AmVestors.

     All other adjusted pre-tax operating losses increased $2.4 million in 1999
and decreased $1.2 million in 1998. The changes from year to year primarily
related to the changes in expenses discussed previously.

     Interest expense increased by $1.2 million in 1999 to $28.3 million
compared to $27.1 million in 1998 and $15.0 million in 1997. The increased
interest expense in 1999 was primarily due to higher interest rates on the
senior notes and adjusted conversion-rate equity security units outstanding
during 1999 as compared to the revolving credit agreement borrowings outstanding
during 1998. The increased interest expense in 1998 was primarily due to
increased debt levels from the 1997 fourth quarter acquisitions of Delta and
AmVestors.

     Income tax expense increased by $3.7 million in 1999 to $32.1 million
compared to $28.4 million in 1998 and $22.0 million in 1997. The effective tax
rate in 1999 was 32.5% compared to 31.2% in 1998 and 27.5% in 1997. The increase
in the effective rate in 1999 was primarily due to a $0.3 million decrease in
tax credits generated by affordable housing and historic rehabilitation
investments and the capitalization of $1.8 million of demutualization costs for
income tax purposes. The increase in the effective tax rate in 1998 was
primarily due to a $2.4 million increase in goodwill amortization and a $0.8
million decrease in tax credits generated by affordable housing and historic
rehabilitation investments. Tax credits generated from these investments totaled
$5.2 million in 1999 compared to $5.5 million in 1998 and $6.3 million in 1997.

     The equity in earnings of unconsolidated subsidiary represents 34% of the
net income of AMAL Corporation, net of goodwill amortization. AMAL Corporation
is the joint venture partner through which the Company markets variable life and
variable annuity products and selected fixed annuity products.

     Net income increased by $3.9 million to $66.7 million in 1999 compared to
$62.8 million in 1998 and $58.1 million in 1997. The increase in 1999 net income
resulted from the increased pre-tax adjusted operating income from the Life
Insurance operations and Annuity operations, which was partially offset by
reorganization costs, increased interest expense, higher effective income tax
rates, and lower income from AMAL Corporation. The increase in net income in
1998 was primarily from increased annuity operating income which was partially
offset by lower realized gains on investments and increased interest expense and
a higher effective income tax rate.

LIQUIDITY AND CAPITAL RESOURCES

THE COMPANY

     The Company's 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 the Company by AmerUs Life),
investment income on assets held by the Company and fees which the Company
charges its subsidiaries and certain other of its affiliates for services,
offset by the expenses incurred for debt service, salaries and other expenses.

     The Company intends to rely primarily on dividends and interest income from
its life insurance subsidiaries in order to make dividend payments to its
shareholders. The payment of dividends by its life insurance subsidiaries is
regulated under various state laws. Under Iowa law, AmerUs Life and Delta Life
may pay dividends only from the earned surplus arising from their respective
businesses and must receive the prior approval of the Iowa Insurance
Commissioner to pay any dividend that would exceed certain statutory
limitations. The current statute limits any dividend, together with dividends
paid out within the preceding 12 months, to the greater of (i) 10% of the
respective company's policyowners' 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. The payment of dividends by AmVestors' subsidiaries,
American and FBL is regulated under Kansas law, which has statutory limitations
similar to those in place in Iowa. Based on these limitations and 1998 results,
the Company's subsidiaries could have paid an estimated $60.7 million in
dividends in 1999 without obtaining regulatory
                                       23
<PAGE>   26

approval. Of this amount, the Company's subsidiaries paid the Company $48
million in dividends in 1999. Based on 1999 results, the Company's subsidiaries
could pay an estimated $61.1 million in dividends in 2000 without obtaining
regulatory approval.

     The Company and its subsidiaries generated cash flows from operating
activities of $632.3 million, $479.4 million and $224.4 million for the years
ended December 31, 1999, 1998 and 1997, respectively. Excess operating cash
flows were primarily used to increase the Company's investment portfolio, fund
policyowner account withdrawals and purchase common stock for the treasury.

     The Company has a $150 million revolving credit facility with a syndicate
of lenders (the "Bank Credit Facility"). As of December 31, 1999, there was a
$32 million outstanding loan balance under the facility. The Bank Credit
Facility provides for typical events of default and covenants with respect to
the conduct of the business of the Company and its subsidiaries and requires the
maintenance of various financial levels and ratios. Among other covenants, the
Company (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 Life and Delta Life, to maintain
certain ratings from A.M. Best and certain levels of adjusted capital and
surplus and risk-based capital.

     During 1999, the Company entered into two $250 million separate account
funding agreements, of which one remained outstanding as of December 31, 1999.
Under this agreement, a five-year floating rate insurance contract is issued to
a commercial paper conduit. The funding agreement is secured by assets in the
Company's separate account and is further backed by the general account assets.
The separate account assets are legally segregated and are not subject to the
claims that arise out of any other business of the Company. The separate account
assets and liabilities are included with general account assets in the financial
statements. The funding agreement may not be cancelled by the commercial paper
conduit unless there is a default under the agreement, but the Company may
terminate at any time.

     During 1999 and 1998, the Company purchased 385,200 shares and 4,325,019
shares of common stock for the treasury at a total cost of $8.9 million and
$102.1 million, respectively.

LIFE INSURANCE SUBSIDIARIES

     The cash flows of the Company's 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, payment of debt, income
taxes and current operating expenses. Life insurance companies generally produce
a positive cash flow from operations, as measured by the amount by which cash
flows 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 the Company's life insurance subsidiaries.

     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. The Company continuously monitors
benefits and surrenders to provide projections of future cash requirements. As
part of this monitoring process, the Company performs cash flow testing of its
assets and liabilities under various scenarios to evaluate the adequacy of
reserves. In developing its investment strategy, the Company 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 the
Company's life insurance subsidiaries.

     The Company takes into account asset/liability management considerations in
the product development and design process. Contract terms for the Company's
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 liabilities for interest-sensitive life products
and annuities by their contractual withdrawal provisions at December 31, 1999
(including liabilities in both the Closed Block and the general account):

(A) Includes $1,216.3 million of statutory liabilities with a contractual
     surrender charges of less than five percent of the account balance.

     AmerUs Life and its joint venture partner are contingently liable in the
event the joint venture, AVLIC, cannot meet its policyholder obligations. At
December 31, 1999, AVLIC had statutory assets of $2,559.1 million, liabilities
of $2,517.5 million, and surplus of $41.6 million.

     Through its membership in the Federal Home Loan Bank (FHLB) of Des Moines,
AmerUs Life is eligible to borrow on a line of credit available to provide it
additional liquidity. Interest is payable at a current rate at the time of any
advance. As of December 31, 1999, AmerUs Life had a $25 million open secured
line of credit against which there were no borrowings. In addition to the line
of credit, AmerUs Life has long-term advances from the FHLB outstanding of $16.1
million at December 31, 1999.

     The Company's life insurance subsidiaries may also obtain liquidity through
sales of investments. The Company's investment portfolio as of December 31, 1999
had a carrying value of $9 billion, including Closed Block investments.

     At December 31, 1999, the statutory surplus of the Company's subsidiaries
was approximately $425.0 million. The Company believes that this level of
statutory capital is more than adequate as each life insurance subsidiary's
risk-based capital is significantly in excess of required levels.

     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 the Company as the Company will have access to the
public debt and equity markets.

INVESTMENT PORTFOLIO

GENERAL

     The Company maintains a diversified portfolio of investments which is
supervised by an experienced in-house staff of investment professionals. The
Company employs sophisticated asset/liability management techniques in order to
achieve competitive yields, while maintaining risk at acceptable levels. The
asset
                                       25
<PAGE>   28

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 Investment Committee of the Board of
Directors of each of the life insurance companies and are overseen by the
Investment Committee of the Board of Directors of the Company. Management
regularly monitors individual assets and asset groups, in addition to monitoring
the overall asset mix. In addition, the insurance company boards and the
Investment Committee review investment guidelines and monitor internal controls.

INVESTMENT STRATEGY

     The Company's 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.

     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. The
Company utilizes analytical systems to establish an optimal asset mix for each
line of business. The Company 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.

INVESTED ASSETS

     The Company maintains a diversified portfolio of investments, including
public and private fixed maturity securities, commercial mortgage loans and
equity real estate. The Company's 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 the Company's
earnings goals.

     The Closed Block was formed to give certain policyowners additional
assurances as to the dividend policies of the Company. As a result of
establishing the Closed Block on June 30, 1996, the Company allocated certain
assets from its investment portfolio to the Closed Block (see Note 1 to the
Consolidated Financial Statements for further discussion). The following table
summarizes consolidated invested assets by asset category as of December 31,
1999 and 1998, and sets forth the allocation of such assets between the Closed
Block and the general account. The remaining information relating to the
Company's 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 investments are mortgage-related securities including commercial
mortgage-backed securities (CMBS), collateralized mortgage obligations (CMOs),
and pass-through mortgage securities. Asset-backed securities are both
residential and non-residential including exposure to home equity loans, home
improvement loans, manufactured housing loans as well as securities backed by
loans on automobiles, credit cards, and other collateral or collateral bond
obligations. Residential mortgage pass-through and CMOs total $1,630.5 million
or 18.2% of total invested assets. Asset-backed residential mortgages total
$361.3 million or 4.0% of total invested assets. As of December 31, 1999, MBS
were $1,774.1 million or 19.8%, of total invested

                                       28

assets of which $1,420.6 million or 80.0% of MBS were from government sponsored
enterprises. Other MBS were $353.5 million or 20.0%, of MBS as of December 31,
1999. Management believes that the quality of assets in the MBS portfolio is
generally high, with 94% of such assets representing agency backed or "AAA"
rated securities.

     The Company uses interest rate swaps, caps, and options to reduce its
exposure to changes in interest rates and to manage duration mismatches. The
Company also uses call options to hedge equity-indexed annuities. Although the
Company is subject to the risk that counterparties will fail to perform, credit
standings of counterparties are monitored regularly. The Company only enters
into transactions with highly rated counterparties. The Company 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, caps, and
options, which represent the extent of the Company's involvement in such
contracts but not the risk of loss, at December 31, 1999, amounted to $640.9
million. The swaps had no carrying value at December 31, 1999 and a fair value
which amounted to a net receivable position of $3.3 million at December 31,
1999. The carrying value and fair value of options amounted to $91.9 million and
$121.7 million, respectively. The interest rate caps and options are reflected
as "other investments" on the Company's consolidated financial statements as of
December 31, 1999. The net amount payable or receivable from interest rate swaps
and caps are accrued as an adjustment to interest income.

MORTGAGE LOANS

     As of December 31, 1999, mortgage loans in the Company's investment
portfolio were $615.2 million, or 6.9% of the aggregate carrying value of
invested assets, including the Closed Block. As of December 31, 1999, commercial
mortgage loans and residential mortgage loans comprised 73.2% and 26.8%,
respectively, of the mortgage loans in the Company's investment portfolio.

     Commercial mortgage loans consist primarily of fixed-rate mortgage loans.
As of December 31, 1999, the Company held 380 individual commercial mortgage
loans with an average balance of $1.2 million.

     As of December 31, 1999, no loans in the Company's loan portfolio (as
measured by principal balance) were classified as delinquent or in foreclosure.
As of the same date, only two loans aggregating $2.5 million, or 0.4%, of the
Company's loan portfolio (as measured by principal balance) were classified as
restructured. During 1999, the Company had no foreclosures.

EQUITY REAL ESTATE

     In recent years the Company has significantly reduced its equity real
estate portfolio. As of December 31, 1999, the carrying value of investment real
estate, including the Closed Block, was $1.5 million.

OTHER

     The Company held $297.9 million of policy loans on individual insurance
products as of December 31, 1999. Policy loans are permitted to the extent of a
policy's contractual limits and are fully collateralized by policy cash values.

     As of December 31, 1999, the Company held equity securities of $14.6
million. The largest holding of equity securities, Federal Home Loan Bank, had a
carrying value of $12.3 million as of December 31, 1999.

     The Company held $269.9 million of other invested assets (including
short-term investments) on December 31, 1999. Other invested assets consist
primarily of various joint venture and limited partnership investments and
derivatives.

EFFECTS OF INFLATION AND INTEREST RATE CHANGES

     The Company does not believe that inflation has had a material effect on
its consolidated results of operations.

                                       29

     Interest rate changes may have temporary effects on the sale and
profitability of the annuities and life insurance products offered by the
Company. For example, if interest rates rise, competing investments (such as
annuities or life insurance products offered by the Company's competitors,
certificates of deposit, mutual funds, and similar instruments) may become more
attractive to potential purchasers of the Company's products until the Company
increases the interest rate credited to owners of its annuities and life
insurance products. In contrast, as interest rates fall, the Company attempts to
adjust its credited rates to compensate for the corresponding decline in
reinvestment rates. The Company monitors interest rates and sells annuities and
life insurance policies that permit flexibility to make interest rate changes as
part of its management of interest spreads. However, the profitability of the
Company's products is based upon persistency, mortality and expenses, as well as
interest rate spreads.

     The Company manages its investment portfolio in part to reduce its exposure
to interest rate fluctuations. In general, the market value of its fixed
maturity portfolio increases or decreases in an inverse relationship with
fluctuations in interest rates, and net investment income increases or decreases
in a direct relationship with interest rate changes.

     The Company 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. The Company utilizes analytical systems to establish an
optimal asset mix for each line of business. The Company 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 on a
regular basis 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.
The Company invests in 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. For a further discussion and disclosure of the nature and
extent of the Company's use of derivatives, see Note 14 to the Consolidated
Financial Statements.

FEDERAL INCOME TAX MATTERS

     The Company and its non-life subsidiaries file a consolidated federal
income tax return. The life insurance subsidiaries file separate federal income
tax returns. 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 MATTERS

SFAS 133 AND 137

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 defines derivative instruments
and provides comprehensive accounting and reporting standards for the
recognition and measurement of derivative and hedging activities (including
certain instruments embedded in other contracts). It requires derivatives to be
recorded in the consolidated balance sheet at fair value and establishes
criteria for hedges of changes in the fair value of assets, liabilities or firm
commitments, hedges or variable cash flows or forecasted transactions, and
hedges of foreign currency exposures of net investments in foreign operations.
Changes in the fair value of derivatives not meeting specific hedge accounting
criteria would be recognized in the consolidated statement of operations. In
June 1999, the FASB issued SFAS No. 137, "Accounting for Derivative Instruments
and Hedging Activities -- Deferral of
                                       30
<PAGE>   33

the Effective Date of FASB Statement No. 133." SFAS No. 137 delays the effective
date of SFAS No. 133 for all fiscal quarters until fiscal years beginning after
June 15, 2000. The Company is evaluating SFAS No. 133 and has not determined its
effect on the consolidated financial statements.

SOP 97-3

     On January 1, 1999, the Company adopted the American Institute of Certified
Public Accountants (AICPA) Statement of Position (SOP) 97-3, "Accounting by
Insurance and Other Enterprises for Insurance-Related Assessments." This
statement provides guidance on when an insurance or other enterprise should
recognize a liability for guaranty fund and other assessments and on how to
measure such liability. The adoption of SOP 97-3 had no material impact on the
financial position or results of operations as the Company currently estimates
assessment liabilities when a determination of an insolvency has occurred.

SOP 98-1

     On January 1, 1999, the Company adopted AICPA SOP 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use." This SOP
provides guidance for determining whether costs of software developed or
obtained for internal use should be capitalized or expensed as incurred. In the
past, the Company has expensed such costs as they were incurred. The adoption of
SOP 98-1 had no material impact on the financial position or results of
operations of the Company.

STATUTORY ACCOUNTING CODIFICATION

     The NAIC has codified statutory accounting practices, which are expected to
constitute the only source of prescribed statutory accounting practices and are
effective in 2001. Codification will change prescribed statutory accounting
practices and may result in changes to the accounting practices that insurance
enterprises use to prepare their statutory financial statements. The changes of
codification will not have a material impact on statutory surplus.

YEAR 2000 COMPLIANCE

     In connection with the year 2000, an important business issue emerged
regarding how existing application software programs and operating systems could
accommodate the date value "2000". Many existing application software products
were designed to accommodate only a two-digit date position which represents the
year (i.e., 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
information technology systems will be able to process accurately.

     The Company formed a Year 2000 working group to address potential problems
posed by this development to assure that the Company was prepared for the year
2000. The Company's overall Year 2000 compliance initiatives included the
following components: (i) assessment of all business critical systems (business
critical systems include computer and embedded systems); processes and external
interfaces and dependencies; (ii) remediation or upgrading of business critical
systems; (iii) testing of both modified and updated systems as well as
integrated systems testing; (iv) implementation of modified and updated systems;
and (v) contingency planning.

     The Company completed the Year 2000 modifications, conversions and testing
and, to date, has not experienced any significant operational difficulties in
2000.

     Total costs associated with Year 2000 modifications and conversions were
approximately $8.5 million, with approximately $4.3 million incurred for the
year ended December 31, 1999. These costs were expensed as incurred.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The main objectives in managing the investment portfolios of the Company
and its insurance subsidiaries are to maximize investment income and total
investment returns while minimizing credit risks in order to provide maximum
support to the insurance underwriting operations. Investment strategies are
developed based on many factors including asset liability management, regulatory
requirements, fluctuations in interest rates and consideration of other market
risks. Investment decisions are centrally managed by investment professionals
based on guidelines established by management and approved by the boards of
directors.

     Market risk represents the potential for loss due to adverse changes in the
fair value of financial instruments. The market risks related to financial
instruments of the Company and its subsidiaries primarily relate to the
investment portfolio, which exposes the Company to risks related to interest
rates and, to a lesser extent, credit quality and prepayment variation.
Analytical tools and monitoring systems are in place to assess each of these
elements of market risk.

     Interest rate risk is the price sensitivity of a fixed income security to
changes in interest rates. Management views these potential changes in price
within the overall context of asset and liability management. Company actuaries
estimate the payout pattern of our liabilities, primarily the Company's
lapsation, to determine duration, which is the present value of the fixed income
investment portfolios after consideration of the duration of these liabilities
and other factors, which management believes mitigates the overall effect of
interest rate risk for the Company.

     The table below provides information about the Company's fixed maturity
investments and mortgage loans at December 31, 1999. The table presents cash
flows of principal amounts and related weighted average interest rates by
expected maturity dates. The cash flows are based on the earlier of the call
date or the maturity date or, for mortgage-backed securities, expected payment
patterns. Actual cash flows could differ from the expected amounts.

</TABLE>

     The Company and its subsidiaries have consistently invested in high quality
marketable securities. As a result, management believes that the Company has
minimal credit quality risk. Fixed maturity securities are comprised of U.S.
Treasury, government agency, mortgage-backed and corporate securities.
Approximately 72% of fixed maturity securities are issued by the U.S. Treasury
or U.S. government agencies or are rated A or better by Moody's, Standard and
Poor's, or the NAIC. Less than 8% of the bond portfolio is below investment
grade. Fixed maturity securities have an average maturity of approximately 7.64
years.

     Prepayment risk refers to the changes in prepayment patterns that can
either shorten or lengthen the expected timing of the principal repayments and
thus the average life and the effective yield of a security. Such risk exists
primarily within the Company's portfolio of mortgage-backed securities.
Management monitors such risk regularly. The Company invests primarily in those
classes of mortgage-backed securities that are less subject to prepayment risk.

     The Company's use of derivatives is generally limited to hedging purposes
and has principally consisted of using interest rate swaps, caps, swaptions and
options. These instruments, viewed separately, subject the Company to varying
degrees of market and credit risk. However when used for hedging, the
expectation is that these instruments would reduce overall market risk. Credit
risk arises from the possibility that counterparties

                                       32
<PAGE>   35

may fail to perform under the terms of the contracts. (See Note 14 of the
Consolidated Financial Statements for additional information).

     Equity price risk is the potential loss arising from changes in the value
of equity securities. In general, equities have more year-to-year price
variability than intermediate term grade bonds. However, returns over longer
time frames have been consistently higher. The Company's equity securities are
high quality and readily marketable.

     All of the above risks are monitored on an ongoing basis. A combination of
in-house systems and proprietary models and externally licensed software are
used to analyze individual securities as well as each portfolio. These tools
provide the portfolio managers with information to assist them in the evaluation
of the market risks of the portfolio.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
  AmerUs Life Holdings, Inc.:

     We have audited the accompanying consolidated balance sheets of AmerUs Life
Holdings, Inc. and subsidiaries as of December 31, 1999 and 1998, and the
related consolidated statements of income, comprehensive income, stockholders'
equity, and cash flows for each of the years in the three-year period ended
December 31, 1999. 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, 1999 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1999, in conformity with generally accepted
accounting principles.

                   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 Preferred Producer agency system, a Personal Producing General
Agents (PPGA) system and national networks of independent agents. The life
insurance and annuity operations are the Company's two operating segments.

ORGANIZATION

     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 this Reorganization which became
effective on June 30, 1996, 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.

     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 of the Class B shares are adjusted to ensure that votes of the Class B
shares together with the votes of Class A shares held by the Class B
shareholders will always have a majority of the votes. AMHC must directly or
indirectly control a majority of the voting shares of the Company. In addition,
as long as the members of AMHC own directly or indirectly more than 50 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.

CONSOLIDATION AND BASIS OF PRESENTATION

     The accompanying consolidated financial statements of the Company and its
wholly-owned subsidiaries have been prepared in conformity with Generally
Accepted Accounting Principles (GAAP) which, as to the insurance company
subsidiaries, differ from statutory accounting practices prescribed or permitted
by regulatory authorities.

     The accompanying consolidated financial statements include the accounts and
operations of the Company and its wholly-owned subsidiaries, principally, AmerUs
Life, AmVestors Financial Corporation (AmVestors), Delta Life Corporation
(Delta) and AmerUs Capital Management Group, Inc. (ACM). All significant
intercompany transactions and balances have been eliminated in consolidation.

     The preparation of consolidated financial statements in conformity with
GAAP requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of

                                      F-11

                           AMERUS LIFE HOLDINGS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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.

     Certain balances for 1997 and 1998 have been reclassified to conform to the
1999 presentation format.

CASH AND CASH EQUIVALENTS

     For purposes of reporting cash flows, the Company includes cash and amounts
due from other financial institutions and interest-bearing deposits in other
financial institutions purchased with original maturities of three months or
less in cash and cash equivalents. Amounts of interest-bearing deposits included
as cash equivalents at December 31, 1999 and 1998 were $48.9 million and $86.5
million, respectively.

CLOSED BLOCK

     The Reorganization contained an arrangement, known as a closed block (the
Closed Block), to provide for dividends on policies that were generally in force
on June 30, 1996 and were within the classes of individual policies for which
AmerUs Life had a dividend scale in effect at the time of the Reorganization.
The primary products included in the Closed Block are whole life, certain
universal life policies and term life insurance policies. 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 Closed Block until the Closed Block is no longer in effect. The
Company will not be required to support the payment of dividends and interest
credits on the Closed Block policies from its general funds, although it could
choose to provide such support. The Company will continue to pay guaranteed
benefits under all policies, including policies included in the Closed Block, in
accordance with their terms. In the event that the Closed Block assets were
insufficient to meet the benefits of the Closed Block guaranteed benefits,
general assets would be utilized to meet the contractual benefits of the Closed
Block policyholders.

     The estimated net cash flows assumed in determining the Closed Block
funding consist of premiums from policies included in the Closed Block,
investment income from Closed Block assets, proceeds from maturities and
dispositions of Closed Block assets, less benefits paid on Closed Block
policies, certain expenses funded in the Closed Block, and dividends on Closed
Block policies based on current payable dividend scales. To the extent that the
actual cash flows from the assets allocated to the Closed Block are, in the
aggregate, more favorable than assumed in establishing the Closed Block, total
dividends paid to the Closed Block policyholders in future years will be greater
than the total dividends that would have been paid to such policyholders if the
current payable dividend scales had been continued. Conversely, to the extent
that the actual cash flows from the assets allocated to the Closed Block are, in
the aggregate, less favorable than assumed in establishing the Closed Block,
total dividends paid to the Closed Block policyholders in future years will be
less than the total dividends that would have been paid to such policyholders if
the current payable dividend scales had been continued.

     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. Closed Block underwriting, acquisition and
insurance expenses include premium taxes and guarantee fund assessments. All
other underwriting, acquisition and insurance expenses related to the Closed
Block operations are charged to operations outside 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. Unrealized gains and losses on investments
are included outside of the Closed Block as a component of other comprehensive
income and will be included in the Closed Block operations upon their
realization. Unrealized gains and losses are not included in the determination
of the policyholder obligation.

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, except for certain policies of Delta Life which have
specific investments identified and for which valuation changes and related
unrealized gains and losses are included in future life and annuity policy
benefits. These unrealized gains or losses in stockholders' equity, excluding
certain Delta Life unrealized gains or losses as described above, are reported
net of taxes and adjustments to deferred policy acquisition costs and value of
business acquired.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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.

     The Company has one $250 million separate account funding agreement. Under
this agreement, a five-year floating rate insurance contract is issued to a
commercial paper conduit. The funding agreement is secured by assets in the
Company's separate account and is further backed by the general account assets.
The separate account assets are legally segregated and are not subject to claims
that arise out of any other business of the Company. The separate account assets
and liabilities are included with general account assets in the financial
statements. The funding agreement may not be cancelled by the commercial paper
conduit unless there is a default under the agreement, but the Company may
terminate at any time.

     Investments in partnerships and joint ventures are accounted for under the
equity method whereby the Company initially records the investment at cost.
Subsequently, the Company increases or decreases the carrying amount of the
investment for its share of income or loss, respectively, of the investee. The
Company is primarily a limited partner in such investments.

MORTGAGE LOANS

     Loans are stated at the principal amounts outstanding, net of unearned
income, deferred loan fees, discounts, and allowances for possible losses.
Unearned income, net deferred loan fees, premiums, and discounts on loans which
are probable of collection are amortized over the terms of the loans using a
method that approximates the interest method. A loan is considered impaired if
it is probable that contractual amounts due will not be collected. Impaired
loans are valued at the fair value of the underlying collateral. Accrued
interest receivable in arrears which management believes is doubtful of
collection is charged against income. Subsequent interest income is not
recognized on such loans until collected or until determined by management to be
collectible.

REAL ESTATE

     Real estate is stated at cost less accumulated depreciation. Depreciation
is calculated over the estimated useful lives using primarily accelerated
depreciation methods.

INTEREST RATE SWAPS, CAPS, SWAPTIONS AND OPTIONS

     The Company uses interest rate swaps, caps, swaptions and options as part
of its overall interest rate risk management strategy for certain life insurance
and annuity products. The book values of the underlying hedged investments or
anticipated investment transactions are amortized over the remaining lives of
the
                                      F-14

                           AMERUS LIFE HOLDINGS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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.

     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.

     The Company has equity-indexed annuity products that guarantee the return
of principal to the customer and credits interest based on a percentage of the
gain in the S&P 500 Index -Registered Trademark-. A portion of the premium from
each customer is invested in investment grade fixed income securities to cover
the minimum guaranteed value due the customer at the end of the term. A portion
of the premium is used to purchase S&P 500 call options to hedge the growth in
interest credited to the customer as a direct result of increases in the S&P 500
Index -Registered Trademark-. The amounts to be paid or received pursuant to
these agreements are accrued and recognized in income over the life of the
agreements. The initial cost of an option agreement is amortized to 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 method of
amortizing deferred policy acquisition costs for traditional life insurance
products varies, 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 statutory surplus. Deferred policy acquisition costs for participating
traditional life insurance are generally amortized over the life of the policies
in proportion to the present value of estimated gross margins. Non-participating
traditional life insurance deferred policy acquisition costs are 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
generally amortized 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
margins on the underlying policies vary from previous estimates. The deferred
policy acquisition cost asset is adjusted for the impact on estimated gross
profits of net unrealized gains and losses on securities.

VALUE OF BUSINESS ACQUIRED

     Value of Business Acquired (VOBA) from insurance companies acquired
represents the portion of the purchase price allocated to the right to receive
future cash flows from insurance contracts existing at the date of the
acquisition. This cost of policies purchased represents the actuarially
determined present value of the projected future cash flows from the acquired
policies.

                                      F-15
<PAGE>   60
                           AMERUS LIFE HOLDINGS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The expected future cash flows used in determining such value are based on
actuarially determined projections of future premium receipts, mortality,
surrenders, operating expenses, changes in insurance liabilities, investment
yields on the assets retained to support the policy liabilities and other
factors. These projections take into account all factors known or expected at
the valuation date, based on the judgment of management. The actual experience
on purchased business may vary from projections due to differences in renewal
premium, investment spread, investment gains or losses, mortality and morbidity
costs and other factors.

     The discount rate used to determine the value of policies purchased is the
rate of return required in order to invest in the business being acquired.
Factors in determining this rate include the cost of capital required to fund
the acquisition; the acquired company's compatibility with other Company
activities that may impact future cash flows; the complexity of the acquired
company; and recent discount rates used by others to determine valuations to
acquire similar blocks of business.

     VOBA is amortized based on the incidence of the expected cash flows using
the interest rate credited to the underlying policies. If cash flows differ from
expectations, the amortization of the VOBA is adjusted. The VOBA asset is
adjusted for the impact on estimated gross profits of net unrealized gains and
losses on securities. Each year, the recoverability of the VOBA is evaluated and
if the evaluation indicates that the existing insurance liabilities, together
with the present value of future net cash flows from the blocks of business
acquired, is insufficient to recover the VOBA, the difference is charged to
expense as an additional write-off of the VOBA.

GOODWILL

     Goodwill represents the excess of the amount paid to acquire a company over
the fair value of its net assets. Goodwill is amortized on a straight-line basis
over a thirty year period. The value of goodwill is monitored based on the
estimates of future earnings. If it is determined that future earnings do not
support the recoverability of goodwill, its carrying value is reduced by a
corresponding charge to expense.

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 7.50 percent.
The weighted average assumed interest rate for all traditional life policy
reserves was 4.33 percent in 1999, 4.30 percent in 1998 and 4.27 percent in
1997. 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.

                           AMERUS LIFE HOLDINGS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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 rates for universal life products were 5.67 percent in 1999, 6.08
percent in 1998 and 6.23 percent in 1997. The range of interest crediting rates
for annuity products, excluding bonus interest payouts, was 4.00 to 7.00 percent
in 1999, 1998 and 1997.

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 approximately 64 percent of
the Company's individual life policies in force (based on face amounts).

PROPERTY AND EQUIPMENT

     Property and equipment is recorded at cost and is depreciated principally
under the straight-line method.

STOCK-BASED COMPENSATION

     Statement of Financial Accounting Standards (SFAS) 123, "Accounting for
Stock-Based Compensation," requires increased disclosure of compensation expense
arising from stock compensation plans. SFAS 123 encourages rather than requires
companies to adopt a new method of accounting for stock compensation awards
based on their estimated fair value at the date they are granted. Companies are
permitted to continue accounting under APB Opinion 25 which requires
compensation cost be recognized based on the difference, if any, between the
quoted market price of the stock on the date of grant and the amount an employee
must pay to acquire the stock. The Company has elected to continue to apply APB
Opinion 25 in its consolidated financial statements and has disclosed proforma
net income and earnings per share information.

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, 1999, 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.

INCOME TAXES

     The Company and its non-life insurance subsidiaries file a consolidated
federal income tax return. The life insurance subsidiaries file separate federal
income tax returns. 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.

EARNINGS PER SHARE

     Basic earnings per share of common stock are computed by dividing net
income by the weighted-average number of common shares outstanding during the
period. Diluted earnings per share assumes the issuance of common shares
applicable to stock options and warrants and is calculated using the treasury
stock method.

TREASURY STOCK

     The Company accounts for its treasury stock using the par value method.
Shares purchased for treasury are not retired and are reissued as needed.

EMERGING ACCOUNTING MATTERS

SFAS 133 AND 137

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 defines derivative instruments
and provides comprehensive accounting and reporting standards for the
recognition and measurement of derivative and hedging activities (including
certain instruments embedded in other contracts). It requires derivatives to be
recorded in the consolidated balance sheet at fair value and establishes
criteria for hedges of changes in the fair value of assets, liabilities or firm
commitments, hedges of variable cash flows or forecasted transactions, and
hedges of foreign currency exposures of net investments in foreign operations.
Changes in the fair value of derivatives not meeting specific hedge accounting
criteria would be recognized in the consolidated statement of operations. In
June 1999, the FASB issued SFAS No. 137, "Accounting for Derivative Instruments
and Hedging Activities -- Deferral of the Effective Date of FASB Statement No.
133." SFAS No. 137 delays the effective date of SFAS No. 133 for all fiscal
quarters until fiscal years beginning after June 15, 2000. The Company is
evaluating SFAS No. 133 and has not determined its effect on the consolidated
financial statements.

SOP 97-3

     On January 1, 1999, the Company adopted the American Institute of Certified
Public Accountants (AICPA) Statement of Position (SOP) 97-3, "Accounting by
Insurance and Other Enterprises for Insurance-Related Assessments." This
statement provides guidance on when an insurance or other enterprise should
recognize a liability for guaranty fund and other assessments and on how to
measure such liability. The adoption of SOP 97-3 had no material impact on the
financial position or results of operations as the Company currently estimates
assessment liabilities when a determination of an insolvency has occurred.

SOP 98-1

     On January 1, 1999, the Company adopted AICPA SOP 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use." This SOP
provides guidance for determining whether costs of software developed or
obtained for internal use should be capitalized or expensed as incurred. In the
past, the Company has expensed such costs as they were incurred. The adoption of
SOP 98-1 had no material impact on the financial position or results of
operations of the Company.

STATUTORY ACCOUNTING CODIFICATION

     The NAIC has codified statutory accounting practices, which are expected to
constitute the only source of prescribed statutory accounting practices and are
effective in 2001. Codification will change prescribed statutory accounting
practices and may result in changes to the accounting practices that insurance
enterprises use to prepare their statutory financial statements. The changes of
codification will not have a material impact on statutory surplus.

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 attempts to minimize 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.

     The Company manages its credit risk associated with these loans by
diversifying its mortgage portfolio by property type and geographic location and
by seeking favorable loan to value ratios on secured properties. The states with
the highest concentration of mortgage loans were Florida, Texas, and Tennessee
with principal balances of $93.6 million, $84.5 million and $38.4 million,
respectively.

     At December 31, 1999 and 1998, the Company's investment in mortgage loans
included $1.7 million and $15.4 million, respectively, in loans that are
considered to be impaired, for which the related allowance for credit losses are
$0.9 million and $4.0 million, respectively. The average recorded investment in
impaired loans during the years ended December 31, 1999 and 1998 was $8.5
million and $18.9 million, respectively. For the years ended December 31, 1999
and 1998, the Company recorded $1.9 million and $0.3 million, respectively, in
interest income on those impaired loans.

     The amounts the Company will ultimately realize from these loans could
differ materially from their carrying values because of future developments
affecting the underlying collateral or the borrower's ability to repay the loans
and leases. As of December 31, 1999, there were no material commitments to lend
additional funds to customers whose loans were classified as nonaccrual or
restructured.

     No mortgage loan on any one individual property exceeded $13 million at
December 31, 1999.

     Provisions for losses are summarized as follows:

     Amortization is recognized in proportion to expected future gross profits
over a 20 year period and is based on the average interest crediting rates which
range from 4.05% to 7.61% for 1999 and over the next five years. Interest
accrued on the unamortized VOBA amounted to $13.0 million and $14.6 million in
1999 and 1998, respectively, which is netted with the VOBA amortization expense.
The estimated amortization for the next five years is as follows:

(A) The Capital Securities were issued through a wholly-owned subsidiary trust,
    AmerUs Capital I. 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.

(B) The Adjustable Conversion-rate Equity Security Units were issued through a
    wholly-owned subsidiary trust, AmerUs Capital II. Each unit consists of a
    forward common stock purchase contract for a share at a price of $31.5625
    per share on July 27, 2001, and a quarterly income preferred security
    bearing interest at 6.86% and due July 27, 2003. The Company repurchased
    451,000 units on December 31, 1998 at an average unit price of $22.89. On
    September 10, 1999, the Company repurchased 61,400 units at an average unit
    price of $24.80. These transactions resulted in gains of $2.9 million and
    $0.4 million, respectively, which have been reflected as additions to
    paid-in capital as the gains are primarily attributable to the change in
    value of the forward common stock purchase contract. The Company is
    obligated to mandatorily redeem the capital securities on July 27, 2003. At
    December 31, 1999, 4,080,500 units were outstanding.

     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.

     Federal income tax returns for the Company for years through 1992 are
closed to further assessment of taxes. The Internal Revenue Service is examining
federal income tax returns of the Company for 1993 through 1996. Management
believes adequate provisions have been made for any additional taxes which may
become due with respect to open years.

(8) EMPLOYEE BENEFIT PLANS

DEFINED BENEFIT PLANS

     The Company has defined benefit pension plans which covered substantially
all of the Company's employees, as well as employees of certain other subsidiary
companies of AMHC. The plans provided for benefits based upon years of service
and the employee's compensation. The Company froze the defined benefit pension
plans effective December 31, 1995, and has recognized its portion of a
curtailment gain amounting to $6.2 million. Effective January 1, 1996, the
defined benefit pension plans were replaced by a defined contribution savings
and retirement plan which also replaced the Company's defined contribution
pension plans.

DEFINED CONTRIBUTION PENSION PLANS

     The Company has a defined contribution savings and retirement plan. Company
contributions are non-discretionary and consist of a matching contribution of an
amount equal to 125 percent of employee contributions, up to 4 percent of annual
employee compensation, and an annual contribution of an amount equal to 4
percent of annual employee compensation. Beginning in 1999, the Company uses a
combination of cash and Company common stock for the annual contribution. The
shares for this purpose are provided by the Company's leveraged Employee Stock
Ownership Plan. Compensation expense for the employer match and annual
contribution amounted to $4.1 million, $3.1 million and $3.7 million in 1999,
1998 and 1997, respectively, including $0.5 million of ESOP compensation expense
in 1999.

LEVERAGED EMPLOYEE STOCK OWNERSHIP PLAN

     In connection with the acquisition of AmVestors, the Company has a
leveraged Employee Stock Ownership Plan (ESOP) which was sponsored by AmVestors
for all AmVestors full-time employees with one year of service. The ESOP
acquired AmVestors stock, which was subsequently exchanged for the Company's
stock, through the proceeds of a note payable to American Investors Life
Insurance Company, a subsidiary of AmVestors. The note bears interest at 7.0%
and is payable in annual installments through December 30, 2002. The note had an
unpaid principal balance of $1.4 million and $1.8 million at December 31, 1999
and 1998, respectively.

     The Company makes annual contributions to the ESOP equal to the ESOP's debt
service less dividends received by the ESOP. All dividends received by the ESOP
are used to pay debt service. The ESOP shares initially were pledged as
collateral for its debt. As the debt is repaid, shares are released from
collateral and allocated to active employees of the Company and certain other
subsidiaries of AMHC, based on the proportion of debt service paid in the year.
Beginning in 1999, the released shares are used to fund a portion of the
Company's annual defined contribution savings and retirement plan contribution.

     The Company accounts for its ESOP in accordance with Statement of Position
93-6. Accordingly, as shares are released from collateral, compensation expense,
or a reduction in the annual defined contribution savings and retirement plan
liability, is reported equal to the current market price of the shares, and the
shares become outstanding for earnings-per-share (EPS) computations. ESOP
compensation expense was $0.5 million, $0.4 million and $0.3 million for the
years ended December 31, 1999, 1998 and 1997, respectively.

     At December 31, 1999 and 1998, the Company reinsured 25% and 39%,
respectively, of its equity index annuity reserves amounting to $108.6 million
and $92.6 million, respectively, with an unaffiliated reinsurer. As of the same
dates, the Company also reinsured approximately 1% in each year of its deferred
annuity reserves amounting to $44.2 million and $59.3 million, respectively,
with an unaffiliated reinsurer.

     In the third quarter of 1999, the Company entered into a reinsurance
agreement for the assumption of a block of equity-index annuities of its joint
venture partner, AVLIC. The Company received assets of approximately $57 million
and assumed liabilities of approximately $59 million. A value of business
acquired asset of approximately $2 million was recorded in connection with this
transaction.

     The Company is contingently liable for the portion of the policies
reinsured under each of its existing reinsurance agreements in the event the
reinsurance companies are unable to pay their portion of any reinsured claim.
Management believes that any liability from this contingency is unlikely.
However, to limit the possibility of such losses, the Company evaluates the
financial condition of its reinsurers and monitors concentration of credit risk.

(11) COMMITMENTS AND CONTINGENCIES

     The Company has entered into agreements with various partnerships in which
a subsidiary of AMHC has an interest. Pursuant to these agreements the Company
is obligated to make future capital contributions to the partnerships of up to
$58.3 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, guarantees 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. The Company has also guaranteed
two loans for a fee. At December 31, 1999, outstanding commitments to extend
credit totaled approximately $25.7 million and loan guarantees totaled
approximately $6.6 million.

     The Company has an agreement with Bank One, N.A. whereby the Company
guarantees the payment of loans made to certain of the Company's managers and
executives for the purpose of purchasing Common Stock and ACES pursuant to the
Stock Purchase Program. The liability of the Company in respect of the principal
amount of loans is limited to $25 million. The Company has also guaranteed
interest and all other fees and obligations owing on the loans. Each participant
in the program has agreed to repay the Company for any amounts paid by the
Company under the guarantee in accordance with a reimbursement agreement entered
into between the participant and the Company.

     AmerUs Life 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,

     In the ordinary course of business, the Company and its subsidiaries are
engaged in certain litigation, none of which management believes is material to
the Company's results of operations.

(12) STOCKHOLDERS' EQUITY

     Generally, the stockholders' equity of the Company's insurance subsidiaries
available for distribution to the Company is 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 2000, the Company's insurance subsidiaries can distribute
approximately $61.1 million in the form of dividends to the Company without
prior approval of such regulatory authorities.

STOCK OPTION PLANS

     The Company has two stock incentive plans authorizing the issuance of
incentive and non-qualified stock options to employees, officers and
non-employee directors of the Company. The Company has reserved 1,400,000 shares
and 150,000 shares of Class A Common Stock for issuance under these plans.

     In conjunction with the acquisition of AmVestors, the Company has two
additional plans in which no additional shares may be granted. They are a
non-qualified stock option plan and an incentive stock option plan.

     The Company also has a non-employee stock option plan authorizing the
issuance of stock options or SARs to insurance agents and other non-employees of
the Company. The Company has reserved 100,000 shares of Class A Common Stock for
issuance under this plan. The terms and conditions under this plan are the same
as under the employee stock incentive plans.

     The option price per share under all plans may not be less than the fair
value of the Company's common stock on the date of grant and the term of the
option may not be longer than ten years. Generally, all options have a
three-year vesting schedule with one-third of the options granted vesting at the
end of each of the three years.

     A summary of the Company's stock option plan follows:

     The estimated weighted average fair value of options granted in 1999, 1998
and 1997 was $9.63, $13.03 and $11.68 per share, respectively. The Company
applies Accounting Principles Board Opinion 25 and related Interpretations in
accounting for its stock option plans. Accordingly, no compensation expense has
been recognized for its option plans. Had compensation expense for the Company's
option plans been determined based on the fair value at the grant dates for
awards under those plans consistent with the method prescribed by SFAS 123, the
Company's net earnings and diluted earnings per share for the years ended
December 31, 1999, 1998 and 1997 would have been reduced to the pro forma
amounts indicated below:

RESTRICTED STOCK

     The Company has awarded common stock to eligible employees and non-employee
directors under the two stock incentive plans. The plans have restriction
periods of two to three years tied to employment and/or service. A portion of
the awards were recorded at the market value on the date of the grant as
unearned compensation since common shares were legally issued on that date. The
initial values of these grants are amortized over the restriction periods, net
of forfeitures. The remaining awards, for which common shares will not be issued
until the end of the restriction period, are being accrued net of forfeitures
over the required service period at the market value on the date of issuance.

     Restricted stock and compensation expense information is as follows:

(13) STATUTORY ACCOUNTING PRACTICES

     The Company's insurance subsidiaries' statutory net income was $49.4
million, $61.0 million and $59.0 million in the years ended December 31, 1999,
1998, and 1997, respectively. The Company's insurance subsidiaries' statutory
surplus and capital was $444.6 million, $472.1 million and $577.3 million at
December 31, 1999, 1998 and 1997, respectively. The minimum capital and surplus
requirements in the states of Iowa and Kansas are $5.0 million and $1.2 million,
respectively.

     The Company's insurance subsidiaries are domiciled in Iowa and Kansas and
prepare their statutory-basis financial statements in accordance with accounting
practices prescribed or permitted by those respective state insurance
departments. Prescribed statutory accounting practices include state laws,
regulations, and general administrative rules, as well as a variety of
publications of the 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 has codified statutory accounting practices which are
expected to constitute the only source of prescribed statutory accounting
practices and are effective in 2001. Codification will change prescribed
statutory accounting practices and may result in changes to the accounting
practices that insurance enterprises

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

use to prepare their statutory financial statements. The Company is currently
evaluating the impact of codification on its statutory financial statements,
however, the changes will not have a material impact on statutory surplus.

     The respective insurance departments impose minimum risk-based capital
(RBC) requirements on insurance enterprises that were developed by the NAIC. The
formulas for determining the amount of 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. The life
insurance subsidiaries have exceeded the authorized control level RBC
requirements in each of the years since the inception of the RBC requirement in
1993.

(14) 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 equity-indexed agreements (options) 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 transactions with only highly rated counterparties.

     The credit risk on all financial instruments, whether on or off the balance
sheet, is controlled through an ongoing 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. Interest rate swap agreements, which expire in
2002, 2003 and 2004, generally involve the exchange of interest payments. The
interest rate cap agreements involve the payment of a maximum fixed interest
rate when an indexed rate exceeds that fixed rate. Swaption agreements 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 a
decrease of $1.5 million, $0.8 million and $0.5 million in 1999, 1998 and 1997,
respectively. 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.

EQUITY-INDEXED AGREEMENTS

     The Company enters into financial agreements to manage the equity risk in
its equity-indexed annuities. Call options, which expire beginning in 2000
through 2009, are linked to the index in which the equity-indexed annuity
crediting rates are based. This allows the Company to participate in index
increases if the market advances as a hedge against the higher credited rates.
The amounts to be received or paid pursuant to these agreements are accrued and
recognized as an adjustment to income over the life of the agreements.

(17) 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 stockholders'
equity, although such volatility will

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 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:

     Short-term investments and other investments:  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, 1999, 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, in foreclosure,
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 (annuities primarily) are
stated at the cost the Company would incur to extinguish the liability (i.e.,
the cash surrender value).

     Debt and capital securities:  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.

(18) REORGANIZATION

     On December 20, 1999 the Company and the Company's controlling shareholder,
AMHC, announced that their respective boards of directors had approved plans for
the demutualization of AMHC and the merger of the Company into AMHC following
the demutualization. Upon completion of the demutualization, AMHC would be a
public company and will change its name to AmerUs Group Co. (AmerUs Group).
Members of AMHC will receive approximately 17 million shares of AmerUs Group and
cash or policy credits in excess of $300 million as a result of the
demutualization. Shareholders of the Company will receive shares in AmerUs Group
in a one-for-one exchange. Upon completion of the demutualization, AmerUs Group
will consist of the Company and AMHC's non-life subsidiaries, principally AmerUs
Properties, Inc. and AmerUs Home Equity.

     Approval for the demutualization and merger is needed from the members of
AMHC, the Iowa Insurance Commissioner and shareholders of the Company. The
Company expects to ask for approval of these transactions during the second
quarter of 2000.

(19) SUBSEQUENT EVENTS

     On February 18, 2000, the Company, AMHC and Indianapolis Life Insurance Co.
(ILICO) entered into a definitive agreement for a combination of the companies.
Under these terms, AMHC will proceed with its previously announced
demutualization. ILICO will demutualize separately and ILICO's members will
receive cash, policy credits and stock equivalent to the value of 11.25 million
shares of stock of AmerUs Group. Upon

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

demutualization, ILICO will become a subsidiary of AmerUs Group and will
continue operations as a stock life insurance company.

     As part of the transaction, AMHC made an initial investment of $100 million
in a downstream holding company of ILICO on February 18, 2000.

     ILICO is a 95-year old mutual life insurance and annuity company based in
Indianapolis, Indiana. ILICO and its subsidiaries are licensed to do business in
all 50 states and the District of Columbia. At December 31, 1999, ILICO had
total assets of $6.1 billion and insurance in force of $30.3 billion.

     The contemplated transactions are subject to normal closing conditions,
including appropriate policyholder/member, shareholder and regulatory approvals.
The Company expects the demutualization of ILICO and combination into AmerUs
Group to take place in the fourth quarter of 2000.

     On February 1, 2000, the Company acquired an independent marketing
organization for approximately $18.1 million. Additional consideration may be
paid contingent on the earnings of the acquired company over the next five
years. The assets of the acquired company were approximately $1.6 million as of
December 31, 1999 and the revenues were approximately $10.0 million for the year
then ended.

(20) OPERATING SEGMENTS

     The Company has two operating segments: Life Insurance and Annuities.
Products generally distinguish a segment. A brief description of each segment
follows:

LIFE INSURANCE

     Open Block:  The primary product offerings consist of whole life, universal
life and term life insurance policies. These products are marketed on a national
basis primarily through a Preferred Producer agency system and a Personal
Producing General Agent ("PPGA") distribution system.

     Closed Block:  Closed Block was established for insurance policies which
had a dividend scale in effect as of June 30, 1996. The Closed Block was
designed to provide reasonable assurance to owners of insurance policies
included therein that, after the Reorganization of AmerUs Life, assets would be
available to maintain the dividend scales and interest credits in effect prior
to the Reorganization if the experience underlying such scales and credits
continues. The primary products included in the Closed Block are whole life,
certain universal life policies and term life insurance policies.

ANNUITIES

     The Annuity segment markets fixed annuities on a national basis primarily
through independent brokers and marketing companies. The Annuity segment also
includes one insurance contract issued to a commercial paper conduit.

     The Company uses the same accounting policies and procedures to measure
operating segment income and assets as it uses to measure its consolidated
income from operations and assets with the exception of the elimination of
certain items which management believes are not necessarily indicative of
overall operating trends. For example, net realized capital gains or losses on
investments, excluding gains or losses on convertible debt which are considered
core earnings, are not included as part of operating segment income. These items
are shown between adjusted pre-tax operating income and income from operations
on the following operating segment income tables. Operating segment income is
generally income before non-core realized gains and losses, interest expense,
income taxes and equity in earnings of its unconsolidated subsidiary, AMAL.
Premiums, product charges, policyowner benefits, insurance expenses,
amortization of deferred policy acquisition costs and VOBA and dividends to
policyowners are attributed directly to each operating segment. Net investment
income and core realized gains and losses on investments are allocated

based on directly-related assets required for transacting the business of that
segment. Other revenues and benefits and expenses which are deemed not to be
associated with any specific reportable segment are grouped together in the All
Other category. These items primarily consist of discontinued product lines such
as group and health, and holding company revenues and expenses. The contribution
to the operating income of the life insurance segment from the Closed Block is
reported as a single line item.

     Assets are segmented based on policy liabilities directly attributable to
each segment. All assets allocated to the Closed Block are grouped together and
shown as a separate item entitled "Closed Block Assets."

     There are no significant intersegment transactions.

     Operating segment income and assets are as follows:

income, and cash flows for each of the years in the three-year period ended
December 31, 1999, as contained in Part II, Item 8 of the annual report on Form
10-K for the year 1999. In connection with our audits of the aforementioned

    stock, through the proceeds of a note payable to American Investors Life

the demutualization of AMHC and the merger of the Company into AMHC following
the demutualization. Upon completion of the demutualization, AMHC would be a
public company and will change its name to AmerUs Group Co. (AmerUs Group).

cash or policy credits in excess of $300 million as a result of the
demutualization. Shareholders of the Company will receive shares in AmerUs Group
in a one-for-one exchange. Upon completion of the demutualization, AmerUs Group
will consist of the Company and AMHC's non-life subsidiaries, principally AmerUs
Properties, Inc. and AmerUs Home Equity.

     Approval for the demutualization and merger is needed from the members of
AMHC, the Iowa Insurance Commissioner and shareholders of the Company. The
Company expects to ask for approval of these transactions during the second
quarter of 2000.

(4) SUBSEQUENT EVENTS

     On February 18, 2000, the Company, AMHC and Indianapolis Life Insurance Co.
(ILICO) entered into a definitive agreement for a combination of the companies.
Under these terms, AMHC will proceed with its previously announced
demutualization. ILICO will demutualize separately and ILICO's members will
receive cash, policy credits and stock equivalent to the value of 11.25 million
shares of stock of AmerUs Group. Upon demutualization, ILICO will become a
subsidiary of AmerUs Group and will continue operations as a stock life
insurance company.

     As part of the transaction, AMHC made an initial investment of $100 million
in a downstream holding company of ILICO on February 18, 2000.

     ILICO is a 95-year old mutual life insurance and annuity company based in
Indianapolis, Indiana. ILICO and its subsidiaries are licensed to do business in
all 50 states and the District of Columbia. At December 31, 1999, ILICO had
total assets of $6.1 billion and insurance in force of $30.3 billion.

     The contemplated transactions are subject to normal closing conditions,
including appropriate policyholder/member, shareholder and regulatory approvals.
The Company expects the demutualization of ILICO and combination into AmerUs
Group to take place in the fourth quarter of 2000.

                               PURCHASE AGREEMENT


This Purchase Agreement (this "Agreement") is made as of this 18th day of
February, 2000, by and between American Mutual Holding Company, an Iowa mutual
insurance holding company ("AMHC"), and AmerUs Life Holdings, Inc., an Iowa
corporation ("AMH").

                                    RECITALS

WHEREAS, the Board of Directors of AMHC has approved and will recommend to its
members the Plan of Conversion dated as of December 17, 1999 (as such Plan of
Conversion has been amended by Amendment No. 1 thereto as of February 11, 2000,
the "Plan"), whereby AMHC shall convert to a stock company, change its name to
"AmerUs Group Co." and merge with AMH, and the Board of Directors of AMH has
approved and will recommend to its stockholders the merger of AMH with and into
AMHC, both subject to the terms set forth in the Agreement and Plan of Merger
dated as of December 17, 1999, between AMHC and AMH, as amended by Amendment No.
1 dated as of February 18, 2000 (the "Merger") ( as so amended the "Merger
Agreement");

WHEREAS, AMHC, AMH, Indianapolis Life Insurance Company, an Indiana mutual
insurance company ("Indianapolis Life"), and the Indianapolis Life Group of
Companies, Inc., an Indiana corporation 61.3% of whose common shares are owned
by Indianapolis Life ("ILGC"), intend to enter into a Combination and Investment
Agreement (the "Combination Agreement") whereby, among other things, (i)
Indianapolis Life shall reorganize with and into AMHC, the surviving corporation
in the Merger, (ii) AMHC or AMH shall purchase, and ILGC shall sell, 105.96
shares of non-voting Common Stock of ILGC (collectively with any securities that
are exchanged for such non-voting Common Stock, the "ILGC Stock") for an
aggregate consideration of $100 million, (iii) in certain circumstances,
including certain terminations of the Combination Agreement, Indianapolis Life,
ILGC or their respective affiliates shall repurchase the ILGC Stock from AMHC or
AMH and/or pay certain break-up fees, and (iv) a subsidiary of AMH will manage
certain investments of Indianapolis Life;

WHEREAS, because AMHC has available enough cash to purchase the ILGC Stock
without the necessity of incurring indebtedness and the costs and expenses
related thereto, and because AMHC will be the surviving corporation in the
Merger, AMH has requested that AMHC purchase the ILGC Stock and AMHC has agreed
to accommodate this request subject to the terms and conditions of this
Agreement. AMHC and AMH desire that the relative risks and rewards related to
the ILGC Stock be allocated as if the ILGC Stock was originally purchased by AMH
rather than AMHC, subject to compensating AMHC for the risk of accommodating AMH
pursuant hereto;

WHEREAS, in the event that (A) both (i) Indianapolis Life or any affiliate
thereof has not repurchased the ILGC Stock and (ii) the Plan does not become
effective and the Merger Agreement is terminated, in each case in accordance
with the terms thereof, (B) any non-


<PAGE>   2

permitted encumbrance, pledge, lien, removal or sale described in Section 3.2(a)
occurs, or (C) AMHC delivers to AMH, on a date not more than five (5) business
days prior to the Plan Effective Date, as such term is defined in the Plan, a
written notice exercising the rights of AMHC under this Agreement to cause AMH
to purchase the ILGC Stock (each of (A), (B) and (C) being a "Trigger Event" and
(C) being a "Five-Day Notice Trigger Event"), the parties hereto desire that
AMHC sell and AMH purchase the ILGC Stock in accordance with the terms of this
Agreement; and

WHEREAS, in the event that the Plan does become effective and the closing under
the Merger Agreement occurs, and the ILGC Stock has not been purchased by AMH
pursuant hereto, the parties hereto desire that the ILGC Stock be treated under
the Plan in like manner as the Non-Insurance Subsidiaries (as such term is
defined in the Plan) whereby an amount of cash equal to the Purchase Price (as
defined in Section 1.1 hereof) shall be credited to Net Cash Proceeds (as
defined in the Plan) under and in accordance with the Plan, and that this
Agreement be terminated and be of no further effect.

NOW, THEREFORE, in consideration of the foregoing, the parties hereto agree as
follows:

                                    Article I
                                 Purchase Rights

         Section 1.1 Grant of Purchase Right. Upon the terms and subject to the
conditions set forth herein, AMH hereby irrevocably grants to AMHC the right and
option to cause AMH to immediately purchase in accordance with this Agreement
all of the ILGC Stock held at the time of exercise by AMHC upon the occurrence
of a Trigger Event for an aggregate cash purchase price (the "Purchase Price")
as calculated pursuant to Section 1.3 below. AMH agrees to so purchase from
AMHC, upon delivery of an Exercise Notice, the ILGC Stock for the Purchase
Price.

         Section 1.2 Method of Exercise. AMHC may exercise the put rights hereby
granted to it on any date on or after the occurrence of a Trigger Event by
executing and delivering to AMH (i) a written notice of exercise (the "Exercise
Notice"), and (ii) a photocopy of the certificates representing all the ILGC
Stock held by AMHC to be purchased by AMH, duly endorsed for transfer or
accompanied by a duly executed instrument of assignment at the offices of AMH.
At the time of payment by AMH of the Purchase Price to AMHC, AMHC shall deliver
to AMH the original certificates representing the ILGC Stock free and clear of
all rights, claims, charges, liens and encumbrances whatsoever ("Encumbrances"),
except for those restrictions and options set forth in the Combination
Agreement.

         Section 1.3 Payment of Purchase Price. (a) On or before the 30th day
(or on the Plan Effective Date (as defined in the Plan), in the case of a
Five-Day Notice Trigger Event) after receipt of the Exercise Notice (the
"Closing Date"), AMH agrees that it shall pay in full the Purchase Price to AMHC
by Federal Wire transfer of immediately available funds to an account, or by
such other reasonable means, specified by AMHC in the Exercise Notice. The
Purchase Price to be paid by AMH shall be an amount equal to (i) One Hundred
Million Dollars ($100,000,000) plus a rate of return of Eight percent (8.0%) per
annum (or if the Purchase Price is not paid in full on the Closing Date, a rate
of return of Twelve percent (12.0%) per annum (the

                                      -2-

<PAGE>   3

"Default Rate") for the period beginning on the Closing Date to and including
the date on which the Purchase Price is actually paid), for the period beginning
on the date AMHC purchases the ILGC Stock to and including the date prior to
which the Purchase Price is paid, less (ii) an amount equal to the aggregate
amount of cash dividends or other consideration received by AMHC in respect of
the ILGC Stock during the same period. In the event that the amount set forth in
clause (ii) in the preceding sentence is greater than the amount set forth in
clause (i), then AMHC shall promptly pay to AMH such excess amount. Any break-up
fee under the Combination Agreement shall be paid to AMH.

                  (b) AMH may elect to cause one or more of its subsidiaries to
purchase the ILGC Stock in accordance with AMH's obligations under this
Agreement. In such event, upon written notice to AMHC, AMH will cause full
payment to be made by such subsidiary to AMHC and AMHC shall make delivery of
the original certificates to such subsidiary upon receipt of the payment of the
Purchase Price, thus satisfying the obligations of both AMH and AMHC under this
Section 1.3. Notwithstanding the foregoing, the election by AMH to cause a
subsidiary to purchase the ILGC Stock shall not relieve AMH of its obligations
as the primary obligor under this Agreement.

                  (c) The obligations of AMH under this Agreement shall be
general obligations of AMH and, to the extent that such treatment does not
violate or provide any new or additional rights to any persons other than AMHC
under any agreement of AMH, the obligations of AMH under this Agreement shall be
treated as pari passu with all non-senior debt of AMH.

         Section 1.4 Payment of Expenses. AMH agrees that it shall pay all of
AMHC costs and expenses relating to this Agreement, to AMHC's acquisition of the
ILGC Stock, including the costs and expenses of its advisors, and to AMHC's
costs of collection if AMH defaults in its obligation to pay timely the Purchase
Price.

                                   Article II
                         Representations and Warranties

         Section 2.1 Representations and Warranties of AMH. AMH hereby
represents and warrants to AMHC that, on the date of this Agreement:

                  (a) The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly

transactions contemplated hereby and thereby, and the compliance with the terms,

any material lease, indenture, mortgage, loan, or credit agreement or any other
agreement or instrument to which AMH is a party or by which it or its assets may
be bound or affected; (iii) violate or constitute a breach of any decision,

the States of Iowa, Kansas, Indiana, New York, Massachusetts and Arizona (such
Commissioners being collectively, the "Insurance Authorities") and any required
securities or broker-dealer approvals, no consent or approval of, or filing and
expiration of a waiting period or a period for disapproval by, any governmental
authority is required for AMH to consummate the transactions contemplated by
this Agreement, except for any such approval which the failure to obtain would
have, or could reasonably be expected to have, a material adverse effect on AMH.

                  (d) There is no encumbrance, pledge or lien against the Assets
(as defined in Section 3.2(a)) under current loan documents binding AMH or its
subsidiaries.

         Section 2.2 Representations and Warranties of AMHC. AMHC hereby
represents and warrants to AMH that, on the date of this Agreement:

                  (a) The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action of AMHC. This Agreement has been
duly and validly executed and delivered by AMHC and, assuming the due and valid
authorization, execution and delivery of this Agreement by AMH, constitutes a
legal, valid and binding obligation of AMH, enforceable against it in accordance

transactions contemplated hereby and thereby, and the compliance with the terms,
conditions and provisions hereof by AMHC do not (i) contravene any provisions of
AMHC's articles of incorporation or by-laws; (ii) conflict with or result in a

material lease, indenture, mortgage, loan, or credit agreement or any other
agreement or instrument to which AMHC is a party or by which it or its assets
may be bound or affected; (iii) violate or constitute a breach of any decision,

                  (d) AMHC is and on the Closing Date will be the record and
beneficial owner of the ILGC Stock, free and clear of all Encumbrances except
for those restrictions and options set forth in the Combination Agreement.

                                   Article III
                                    Covenants

         Section 3.1 Approvals, etc. In the event that any notification is
required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, in connection with the purchase by AMHC or AMH of the ILGC Stock, or in
the event any other consent, approval or authorization of, or declaration of or
filing with, or other action by, any person (including, without limitation, any
governmental authority) is required after the date hereof pursuant to applicable
law as a condition precedent to the performance by AMH of this Agreement and/or
the purchase by AMH of the ILGC Stock, upon the exercise by AMHC in accordance
with the terms hereof, then each of AMH and AMHC shall use its reasonable best
efforts to obtain the same not later than the date upon which AMH is obligated
to perform its obligations hereunder.

         Section 3.2 Maintenance of Liquidity. (a) Until the Closing Date, AMH
will not, directly or indirectly, create, incur, assume, or suffer to exist any
encumbrance, pledge or lien of any kind upon (except for any encumbrance, pledge

Agreement to the extent required by the existing loan agreements as of the date
hereof), nor will it sell, lease or otherwise dispose of, the assets listed on
Schedule I ("Assets"), attached hereto and made a part hereof, which assets
have, as of the date of this Agreement, a fair market value of $110 million. AMH
shall have the right from time-to-time after the date of this Agreement to
substitute for all or a portion of the Assets other assets of AMH of equivalent
or greater fair market value, liquidity and credit quality which assets shall
become "Assets" hereunder. If AMH is not otherwise able to fund the Purchase
Price, AMH shall use the Assets to do so.

         (b) Upon execution of this Agreement, AMHC, AMH and the custodian
currently holding the Assets pursuant to agreements with AMH and its
subsidiaries (the "Custodian") shall enter into an agreement (the "Notification
Agreement") in such form and with such terms upon which such parties mutually
agree to cause the Assets to be held during the term of this Agreement with the
Custodian and to cause the Custodian (i) to deliver to Nicholas Critelli,
counsel to the AMHC

                                      -5-

Special Board Committee, or such other person as may be designated by Mr.
Critelli, upon request by Mr. Critelli and no less frequently than on a monthly
basis, written confirmation that the Assets continue to be held by the Custodian
and (ii) to deliver to Mr. Critelli immediate notice of any encumbrance, pledge,
lien, removal or sale of the Assets. AMH shall immediately notify the Custodian
of any encumbrance, pledge, lien, removal or sale of the Assets. The Chief
Financial Officer of AMH shall certify each report delivered under clause (ii)
of the preceding sentence and shall deliver to the AMHC Special Board Committee
each week a certification that the Assets (or substitutions therefor permitted
by Section 3.2(a)) continue to be held by the Custodian. Any such encumbrance,
pledge, lien, removal or sale of the Assets not permitted by Section 3.2(a)
shall be considered a Trigger Event for purposes of this Agreement.

                                   Article IV

changes contemplated by this Agreement, with the same force and effect as if
made on and as of the Closing Date, except in such cases where the failure to be
so true and correct would not have a material adverse effect on AMH.

                  (b) Agreements and Covenants. AMH shall have performed or
complied in all material respects with all agreements and covenants required by
this Agreement to be performed or complied with by them at or prior to the
Closing Date.

adverse effect on AMHC.

                          AGREEMENT AND PLAN OF MERGER


This Agreement and Plan of Merger (this "Agreement") is made as of this 17th day
of December, 1999, by and between American Mutual Holding Company, an Iowa
mutual insurance holding company (to be converted to a stock company pursuant to
Chapters 521A and 508B of the Code of Iowa and renamed "AmerUs Group Co.")
("AMHC"), and AmerUs Life Holdings, Inc., an Iowa corporation ("AMH").

                                    RECITALS

WHEREAS, the Board of Directors of AMHC deems it advisable and in the best
interest of AMHC and its members that AMHC convert into a stock company and
merge with AMH with AMHC as the surviving corporation;

WHEREAS, the Board of Directors of AMH deems it advisable and in the best
interest of AMH and its stockholders that AMH merge with and into AMHC;

WHEREAS, the Board of Directors of AMHC has approved and will recommend to its
members the Plan of Conversion dated as of December 17th, 1999 (the "Plan"),
whereby AMHC shall convert to a stock company, change its name to "AmerUs Group
Co." and merge with AMH, and the Board of Directors of AMH has approved and will
recommend to its stockholders the merger of AMH with and into AMHC, both subject
to the terms set forth herein (the "Merger"); and

WHEREAS, for U.S. federal income tax purposes, it is intended that this
Agreement be a "plan of reorganization" within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code").

NOW, THEREFORE, in consideration of the foregoing, the parties hereto agree as
follows:

                                   Article III
                     Conversion of Shares; Effect of Merger

         Section 3.1 Conversion; Exchange Ratio. At the Effective Time, by
virtue of the Merger and without any action on the part of any holder of capital
stock of AMH or AMHC:

                  (a) Each share of (i) Class A Common Stock, no par value, of
AMH (the "Class A Shares"), and (ii) Class B Common Stock, no par value, of AMH
(the "Class B Shares," and together with the Class A Shares, the "AMH Shares"),

                  (d) Notwithstanding anything in this Agreement to the
contrary, AMH Shares held by a person (a "Dissenting Stockholder") who complies
with all the provisions of Iowa law concerning the right of holders of AMH
Shares to dissent from the Merger and require appraisal of their AMH Shares
("Dissenting Shares") shall not be converted as described in Section 3.1(a) but
shall become the right only to receive such consideration as may be determined
to be due to such Dissenting Stockholder pursuant to the laws of the State of
Iowa. If, after the Effective Time, such Dissenting Stockholder withdraws his
demand for appraisal or fails to perfect or otherwise loses his right of
appraisal, in any case pursuant to the IBCA, his AMH Shares shall be deemed
converted as of the Effective Time into the right to receive AMHC Shares as
provided in Section 3.1(a).

         Section 3.2 Exchange of Shares. At the Effective Time, the stock
transfer books of AMH shall be closed as to the holders of capital stock of AMH
immediately prior to the Effective Time and no transfer of capital stock of AMH
by any such holder shall thereafter be made or recognized. If, after the
Effective Time, certificates which represented AMH Shares immediately prior to
the Effective Time are properly presented in accordance with Section 3.3 hereof
to the exchange agent, ChaseMellon Shareholder Services, L.L.C. (hereinafter
referred to as the "Exchange Agent"), such certificates shall be cancelled and
exchanged for certificates representing the number of AMHC Shares into which the
AMH Shares represented thereby were converted in the Merger.

         Section 3.3 Exchange Procedure. (a) At or prior to the Effective Time,
AMHC shall deposit, or shall cause to be deposited, with the Exchange Agent, for
the benefit of the holders of certificates formerly representing AMH Shares
("Old Certificates"), for exchange in accordance with this Article III,
certificates representing the AMHC Shares ("New Certificates") to be issued
pursuant to this Article III in exchange for outstanding AMH Shares.

                  (b) As promptly as practicable after the Effective Time, AMHC
shall send or cause to be sent to each holder of record of AMH Shares
immediately prior to the Effective Time whose shares were converted into the
right to receive AMHC Shares pursuant to Section 3.1 transmittal materials for
use in exchanging such stockholder's Old Certificates for the consideration set
forth in this Article III. AMHC shall cause the New Certificates into which such
stockholder's AMH Shares are converted at the Effective Time to be delivered to
such stockholder upon delivery to and receipt by the Exchange Agent of Old
Certificates representing all such stockholder's AMH Shares (or indemnity
reasonably satisfactory to AMHC and the Exchange Agent, if any of such
certificates are lost, stolen or destroyed). No interest will be paid on any
merger consideration.

                  (c) Until surrendered for exchange in accordance with the
provisions of this Section 3.3, each certificate theretofore representing AMH
Shares (other than shares to be cancelled pursuant to Section 3.1(b) hereof and
Dissenting Shares) shall from and after the Effective Time represent for all
purposes only the right to receive AMHC Shares as set forth in this Agreement.
No dividends or other distributions with respect to AMHC Shares with a record
date occurring after the Effective Time shall be paid to the holder of any
unsurrendered Old Certificate representing AMH Shares converted in the Merger
into the right to receive such AMHC Shares until the holder thereof receives New
Certificates in exchange therefor in



                                      -3-
<PAGE>   4


accordance with the procedures set forth in this Section 3.3. After so receiving
New Certificates, the record holder thereof also shall be entitled to receive
any such dividends or other distributions, without any interest thereon, which
theretofore had become payable with respect to AMHC Shares such holder had the
right to receive upon surrender of the Old Certificates.

         Section 3.4 Transfer Taxes. If any certificate for any AMHC Shares is
to be issued in a name other than the name of the registered owner of the AMH
Shares surrendered, it shall be a condition of such exchange that (i) the person
requesting such exchange shall pay to the Exchange Agent any transfer or other
taxes; or (ii) establish to the satisfaction of the Exchange Agent that all
applicable taxes have been paid or that no taxes are due.

         Section 3.5 Closing. The closing of the transaction contemplated by
this Agreement (the "Closing") shall take place on such date and time and at
such place after satisfaction or waiver of the conditions set forth in Article
VI upon which AMH and AMHC mutually agree and which, to the extent required by
law, are approved by the Iowa Commissioner of Insurance (the "Iowa
Commissioner").

         Section 3.6 No Further Ownership Rights in AMH Stock; No Liability. The
consideration provided pursuant to this Article III to persons identified on the
books and records of AMH as the owners of AMH Shares shall be deemed to have
been paid in full satisfaction of all rights pertaining to the AMH Shares
theretofore existing, and there shall be no further registration of transfers on
the stock transfer books of the Surviving Corporation of the AMH Shares which
were outstanding immediately prior to the Effective Time. None of AMH, AMHC, the
Surviving Corporation or the Exchange Agent shall be liable to any person in
respect of any property delivered in good faith to a public official pursuant to
any abandoned property, escheat or other similar law.

         Section 3.7 AMH Common Stock Rights. Each stock option, restricted
stock award, stock warrant, stock appreciation right and similar common stock
equivalents, instruments or units (each, a "Common Stock Right") outstanding at
the Effective Time which may be exercised for issuance of, converted into or
relating to the AMH Shares (or, in the case of stock appreciation rights, which
are based upon the value of AMH Shares) (each, a "Continuing Common Stock
Right") shall be assumed by AMHC and converted into a stock option, restricted
stock award, a stock warrant or similar common stock equivalent, instrument or
unit, respectively, to purchase, convert into or relate to AMHC Shares (or, in
the case of stock appreciation rights, become based upon the value of AMHC
Shares) wherein (i) the right to purchase or convert into AMH Shares pursuant to
the Continuing Common Stock Right shall be converted into the right to purchase
or convert into that same number of AMHC Shares, (ii) the exercise or conversion
price per share of the AMHC Shares shall be the previous exercise or conversion
price per AMH Share, and (iii) in all other material respects the Continuing
Common Stock Right shall be subject to the same terms and conditions as governed
the Common Stock Right on which it was based, including the length of time
within which the Continuing Common Stock Right may be exercised or converted
(which shall not be extended except that the holder of a Continuing Common Stock
Right who continues in the service of AMHC or a subsidiary of AMHC shall not be
deemed to have terminated service for purposes of determining the Continuing
Common Stock Right exercise or conversion period) and for all Continuing Common



                                      -4-

Stock Rights, such adjustments shall be and are intended to be effected in a
manner which is consistent with Section 424(a) of the Code. At the Effective
Time, AMHC shall assume and adopt the AmerUs Life Holdings, Inc. Non-Employee
Director Stock Plan, the AmerUs Life Holdings, Inc. 1999 Non-Employee Stock
Option Plan, the AmerUs Life Holdings, Inc. Stock Incentive Plan and the AmerUs
Group Co. MIP Deferral Plan, as each such plan is maintained and administered by
AMH at the Effective Time.

                                   Article IV
                         Representations and Warranties

         Section 4.1 Representations and Warranties of AMH.  AMH represents and
warrants to AMHC as follows:

         (a) Organization and Authority. AMH and each of its subsidiaries is a
corporation duly organized, validly existing, and in good standing under the
laws of its jurisdiction of organization, and has full corporate power and
authority to conduct its business and own its property as now conducted and
owned, in each case, except to the extent that the lack of such organization,
existence, good standing, power or authority does not have, nor could reasonably
be expected to have, a Material Adverse Effect (as defined in Section 8.5) on
AMH. Each of AMH and its subsidiaries is duly qualified or licensed and in good
standing as a foreign corporation in each jurisdiction in which the nature of
its business or the ownership or leasing of its property makes such
qualification or licensing necessary other than in such jurisdictions where the
failure to be so qualified or licensed (individually or in the aggregate) would
not result in a Material Adverse Effect with respect to AMH. AMH has the
requisite corporate power and authority to enter into this Agreement and,
subject to approval of this Agreement by the requisite vote of holders of each
of the Class A Shares and Class B Shares, voting as separate classes, and
receipt of necessary regulatory approvals, to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action of AMH, except for the required
approval of the stockholders of AMH of this Agreement. This Agreement has been
duly and validly executed and delivered by AMH and, assuming the due and valid
authorization, execution and delivery of this Agreement by AMHC, constitutes a
legal, valid and binding obligation of AMH, enforceable against it in accordance
with its terms, except as enforceability may be limited by bankruptcy and other
similar laws and general principles of equity.

                  (b) Capitalization of AMH; Ownership of Subsidiary Stock. The
authorized capital stock of AMH consists of 180,000,000 Class A Shares,
50,000,000 Class B Shares and 20,000,000 shares of preferred stock, no par value
("AMH Preferred Stock"). At the close of business on November 1, 1999, an
aggregate of 30,070,854 Class A Shares and Class B Shares and no shares of AMH
Preferred Stock were issued and outstanding, with 25,070,854 Class A Shares and
5,000,000 Class B Shares issued and outstanding, respectively, which comprise
all the issued and outstanding shares of capital stock of AMH. All such issued
and outstanding shares of capital stock of AMH have been duly authorized,
validly issued and are fully paid and non-assessable. AMH owns all the
outstanding shares of capital stock of each of AmerUs Life

Insurance Company, Delta Life Corporation, AmVestors Financial Corporation and
American Capital Management Group, Inc.

                  (c) No Violation of Existing Agreements. Except as set forth
on Schedule 4.1(c), the execution and delivery of this Agreement, together with
all documents and instruments contemplated herein, the consummation of the
transactions contemplated hereby and thereby, and the compliance with the terms,
conditions and provisions hereof by AMH do not (i) contravene any provisions of
AMH's articles of incorporation or by-laws; (ii) conflict with or result in a
breach of or constitute a material default (or an event that might, with the
passage of time or the giving of notice or both, constitute a material default)
or give rise to any right to terminate, cancel or accelerate or to any loss of
material benefit under any of the terms, conditions, or provisions of any
material lease, indenture, mortgage, loan, or credit agreement or any other
agreement or instrument to which AMH is a party or by which it or its assets may
be bound or affected; (iii) violate or constitute a breach of any decision,
judgment or order of any court or arbitration board or of any governmental
department, commission, board, agency or instrumentality, domestic or foreign,
by which AMH is bound or to which it is subject; or (iv) violate any applicable
law, rule, or regulation to which AMH or any of its property is bound, in each
case of clauses (i)-(iv) which has or could reasonably be expected to have a
Material Adverse Effect (as defined in Section 8.5) on AMH.

                  (d) No Consents or Approvals of Governmental Authorities.
Except for any required regulatory approvals, including, without limitation,
approval by the Iowa Commissioner, the Commissioner of Insurance of the State of
Kansas (the "Kansas Commissioner") and any required securities or broker-dealer
approvals and acceptance of the Articles of Merger pursuant to the IBCA, no
consent or approval of, or filing and expiration of a waiting period or a period
for disapproval by, any governmental authority is required for AMH to consummate
the transactions contemplated by this Agreement, except for any such approval
which the failure to obtain would have, or could reasonably be expected to have,
a Material Adverse Effect (as defined in Section 8.5) on AMH.

                  (e) Title to Assets. Each of AMH and its subsidiaries has good
and merchantable title to all material properties and assets which are reflected
and identified as owned by such entities in the financial statements of AMH set
forth in its Quarterly Report on Form 10-Q filed with the Securities and
Exchange Commission (the "SEC") for the fiscal quarter ended September 30, 1999
(the "AMH Quarterly Financial Statements"), other than property disposed of in
the ordinary course of business subsequent to the date of such financial
statements, free and clear of any material mortgage, lien, pledge, charge, claim
or encumbrance, or material right, title and interest in others, except (a) as
reflected or specified in AMH's audited financial statements set forth in its
Annual Report on Form 10-K filed with the SEC for its fiscal year ended December
31, 1998, including the notes thereto and the unaudited quarterly financial
statements of AMH filed on Form 10-Q with the SEC for each of the first three
quarters of 1999, including the notes thereto (collectively, the "AMH Financial
Statements"), (b) the lien of taxes not yet due or payable or being contested in
good faith by appropriate proceedings and (c) such imperfections of title and
encumbrances, if any, as do not materially detract from the value or interfere
with the use of the properties subject thereto or affected thereby or could
otherwise be reasonably expected to result in a Material Adverse Effect (as
defined in Section 8.5) on AMH.



                                      -6-
<PAGE>   7

                  (f) Taxes. Each of AMH and its subsidiaries has filed or
caused to be filed in a timely manner (within any applicable extension periods)
all material tax returns required to be filed by the Code or by applicable state
or foreign tax laws; all taxes shown to be due on such tax returns have been or
will be timely paid in full and no material tax liens have been filed, in each
case, except for filings or payments the absence of which, or liens the
existence of which, would not have nor could reasonably be expected to result in
a Material Adverse Effect (as defined in Section 8.5) on AMH. The Federal
consolidated income tax returns in which AMH and/or any of its subsidiaries
joined have been examined by the Internal Revenue Service for taxable years
through the year ended December 31, 1992 and all material deficiencies resulting
from such examinations have been paid; taxable years through the year ended
December 31, 1996, are currently before the IRS Office of Appeals or under
examination.

                  (g) Undisclosed Liabilities. Except as disclosed in the
Schedules to this Agreement, the AMH Financial Statements, or as incurred in the
ordinary course of business since the date of the AMH Financial Statements,
neither AMH nor any of its subsidiaries has to AMH's knowledge any liabilities
(absolute, accrued, contingent, unknown or otherwise) of a nature which, if
known, would be required to be disclosed on a balance sheet or in the related
notes to the consolidated financial statements prepared in accordance with
generally accepted accounting principles ("GAAP") and which would have, or could
be reasonably expected to have, individually or in the aggregate, a Material
Adverse Effect (as defined in Section 8.5) on AMH.

                  (h) Absence of Material Events. Since September 30, 1999,
there has not been: (a) any change in the business, assets or prospects of AMH
or its subsidiaries which has had or could reasonably be expected to result in a
Material Adverse Effect (as defined in Section 8.5) to AMH, nor, to the
knowledge of AMH, are any such changes threatened, anticipated or contemplated,
or (b) any actual or, to the knowledge of AMH, threatened, anticipated or
contemplated, damage, destruction, loss, conversion, termination, cancellation,
default or taking by eminent domain or other action by governmental authority
which has had or could reasonably be expected to have a Material Adverse Effect
on AMH.

                  (i) Financial Statements. The AMH Financial Statements fairly
present in all material respects the consolidated financial position of AMH and
its subsidiaries as at the respective dates thereof and the consolidated results
of AMH operations and cash flows for the respective periods indicated, in each
case in accordance with GAAP consistently applied, except as may be indicated in
the notes thereto, or, in the case of unaudited interim financial statements, as
may be permitted by GAAP, except for normal and recurring year-end adjustments
and the absence of certain notes.

                  (j) Litigation. Except as set forth in Schedule 4.1(j), there
is no action, suit, investigation or proceeding pending against AMH or its
subsidiaries, or, to AMH's knowledge, threatened against or affecting AMH or its
subsidiaries, before any court or arbitrator or any governmental body, agency or
official relating to the transactions contemplated hereby or which, if
determined or resolved adversely to AMH, could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect (as defined in
Section 8.5) on AMH.



                                      -7-
<PAGE>   8

                  (k) Employee Benefit Plans. Each employee benefit plan of AMH
or its subsidiaries (and each related trust, insurance contract or fund) to the
knowledge of AMH is being maintained and administered in compliance with its
terms and to the knowledge of AMH, AMH has complied in form and in operation in
all respects with the applicable requirements of all laws, regulations and
rulings, including but not limited to ERISA and the Code, and all amounts due
thereunder have been paid, except, in each case to the extent that any such
non-compliance would not, nor could reasonably be expected to result in a
Material Adverse Effect (as defined in Section 8.5) on AMH.

                  (l) Compliance With Laws. To the knowledge of AMH, neither AMH
nor any of its subsidiaries is in conflict with, or in default or violation of
any law, rule, regulation, order, judgment or decree applicable to AMH or any of
its subsidiaries or by which AMH or any of its subsidiaries or any of their
respective properties is bound or affected, in each case except for such matters
which do not have, nor could reasonably be expected to have, a Material Adverse
Effect (as defined in Section 8.5) on AMH. To the knowledge of AMH, (i) no
investigation or review by any governmental entity is pending or threatened
against AMH or any of its subsidiaries, nor has any governmental entity
indicated an intention to conduct the same and (ii) there is no material
judgment, injunction, order or decree binding upon AMH or any of its
subsidiaries, in each case except for such matters which do not have, nor could
reasonably be expected to have, a Material Adverse Effect (as defined in Section
8.5) on AMH.

                  (m) Environmental Matters. Except as set forth in Schedule
4.1(m), to the knowledge of AMH, each of AMH and its subsidiaries is in material
compliance with all applicable federal, state and local laws and regulations
relating to pollution or protection of human health or the environment
(including, without limitation, ambient air, surface water, ground water, land
surface or subsurface strata), including, without limitation, laws, standards
and regulations relating to emissions, discharges, releases or threatened
releases of chemicals, pollutants, contaminants, wastes, toxic substances
hazardous substances, or conditions, petroleum and petroleum products
("Materials of Environmental Concern"), or otherwise relating to the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of Materials of Environmental Concern (collectively,
"Environmental Laws"), which compliance includes, but is not limited to, the
possession by AMH or its subsidiaries of all permits and other governmental
authorizations required under applicable Environmental Laws, and compliance with
the terms and conditions thereof, except in each case any such non-compliance
which does not have, nor could reasonably be expected to have, a Material
Adverse Effect (as defined in Section 8.5) on AMH.

                  Section 4.2 Representations and Warranties of AMHC. AMHC
represents and warrants to AMH as follows:

                  (a) Organization and Authority. AMHC is a mutual insurance
holding company duly organized, validly existing, and in good standing under the
laws of the State of Iowa, and has full corporate power and authority to conduct
its business and own its property as now conducted and owned, except to the
extent that the lack of such organization, existence, good standing, power or
authority does not have, nor could reasonably be expected to have, a Material
Adverse Effect on AMHC. Each of AMHC and its subsidiaries is duly qualified or




                                      -8-
<PAGE>   9

licensed and in good standing as a foreign corporation in each jurisdiction in
which the nature of its business or the ownership or leasing of its property
makes such qualification or licensing necessary other than in such jurisdictions
where the failure to be so qualified or licensed (individually or in the
aggregate) would not have a Material Adverse Effect (as defined in Section 8.5)
on AMHC. AMHC has the requisite corporate power and authority to enter into this
Agreement and, subject to approval of this Agreement by the requisite vote of
its members, and receipt of necessary regulatory approvals, to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized by all necessary corporate action of AMHC, except for the
required approval of the members of AMHC of this Agreement. This Agreement has
been duly and validly executed and delivered by AMHC and, assuming the due and
valid authorization, execution and delivery of this Agreement by AMH,
constitutes a legal, valid and binding obligation of AMHC, enforceable against
it in accordance with its terms, except as enforceability may be limited by
bankruptcy and other similar laws and general principles of equity.

                  (b) Capitalization of AMHC. As of the date of this Agreement,
AMHC has no capital stock authorized, issued or outstanding. The authorized
capital stock of AMHC after conversion to a stock company shall consist of
230,000,000 shares of Common Stock, no par value, and 20,000,000 shares of
preferred stock, no par value. The AMHC Shares, when issued in accordance with
this Agreement, shall be duly authorized, validly issued and fully paid and
non-assessable.

                  (c) No Violation of Existing Agreements. Except as set forth
on Schedule 4.2(c), the execution and delivery of this Agreement, together with
all documents and instruments contemplated herein, the consummation of the
transactions contemplated hereby and thereby, and the compliance with the terms,
conditions and provisions hereof by AMHC do not (i) contravene any provisions of
AMHC's articles of incorporation or by-laws; (ii) conflict with or result in a
breach of or constitute a material default (or an event that might, with the
passage of time or the giving of notice or both, constitute a material default)
or give rise to any right to terminate, cancel or accelerate or to any loss of
material benefit under any of the terms, conditions, or provisions of any
material lease, indenture, mortgage, loan, or credit agreement or any other
agreement or instrument to which AMHC is a party or by which it or its assets
may be bound or affected; (iii) violate or constitute a breach of any decision,
judgment or order of any court or arbitration board or of any governmental
department, commission, board, agency or instrumentality, domestic or foreign,
by which AMHC is bound or to which it is subject; or (iv) violate any applicable
law, rule, or regulation to which AMHC or any of its property is bound, in each
case of clauses (i)-(iv) which has or could reasonably be expected to have a
Material Adverse Effect (as defined in Section 8.5) on AMHC.

                  (d) No Consents or Approvals of Governmental Authorities.
Except as stated in the Plan, and except for any required approval by regulatory
authorities, including, without limitation, securities or broker-dealer
approvals, no consent or approval of, or filing and expiration of a waiting
period or a period for disapproval by, any governmental authority is required
for AMHC to consummate the transactions contemplated by this Agreement, except
for filing and acceptance of the Articles of Merger pursuant to the IBCA, which
the failure to obtain



                                      -9-
<PAGE>   10

would have, or could reasonably be expected to have, a Material Adverse Effect
(as defined in Section 8.5) on AMHC.

                  (e) Title to Assets. Each of AMHC and its subsidiaries has
good and merchantable title to all material properties and assets reflected and
identified as owned by such entities in its financial statements dated as of
September 30, 1999 (the "Quarterly AMHC Financial Statements"), other than
property disposed of in the ordinary course of business subsequent to the date
of such financial statements, free and clear of any material mortgage, lien,
pledge, charge, claim or encumbrance, or material right, title and interest in
others, except (a) as reflected in AMHC's audited financial statements for its
fiscal year ended December 31, 1998, including the notes thereto and the
unaudited quarterly financial statements of AMHC for each of the first three
quarters of 1999 (collectively, the "AMHC Financial Statements"), (b) the lien
of taxes not yet due or payable or being contested in good faith by appropriate
proceedings and (c) such imperfections of title and encumbrances, if any, as do
not materially detract from the value or interfere with the use of the
properties subject thereto or affected thereby or could otherwise be reasonably
expected to result in a Material Adverse Effect (as defined in Section 8.5) on
AMHC.

                  (f) Taxes. Each of AMHC and its subsidiaries has filed or
caused to be filed in a timely manner (within any applicable extension periods)
all material tax returns required to be filed by the Code or by applicable state
or foreign tax laws; all taxes shown to be due on such tax returns have been or
will be timely paid in full and no material tax liens have been filed in each
case, except for filings or payments the absence of which, or liens the
existence of which, would have or could be reasonably expected to have a
Material Adverse Effect (as defined in Section 8.5) on AMHC. The Federal
consolidated income tax returns in which AMHC and/or any of its subsidiaries
joined have been examined by the Internal Revenue Service for all taxable years
through the year ended December 31, 1992 and all material deficiencies resulting

examination.

                  (g) Undisclosed Liabilities. Except as disclosed in the

ordinary course of business since the date of the AMHC Financial Statements,
neither AMHC nor any of its subsidiaries has to AMHC's knowledge any liabilities
(absolute, accrued, contingent, unknown or otherwise) of a nature which, if
known, would be required to be disclosed on a balance sheet or in the related
notes to the consolidated financial statements prepared in accordance with GAAP
and which have, or could be reasonably expected to have, individually or in the
aggregate, a Material Adverse Effect (as defined in Section 8.5) on AMHC.

                  (h) Absence of Material Events. Since December 31, 1998, there
has not been: (a) any change in the business, assets or prospects of AMHC and
its subsidiaries which has had or could be reasonably expected to result in
Material Adverse Effect (as defined in Section 8.5) to AMHC, nor, to the
knowledge of AMHC, are any such changes threatened, anticipated or contemplated
or (b) any actual or, to the knowledge of AMHC, threatened, anticipated or
contemplated, damage, destruction, loss, conversion, termination, cancellation,
default or taking by eminent domain or other action by governmental authority
which has had or could be reasonably expected to have a Material Adverse Effect

resolved adversely to AMHC, may have, individually or in the aggregate, a
Material Adverse Effect on AMHC (as defined in Section 8.5).

and its subsidiaries (and each related trust, insurance contract or fund) to the
knowledge of AMHC is being maintained and administered in compliance with its
terms and to the knowledge of AMHC, AMHC has complied in form and in operation
in all respects with the applicable requirements of all laws, regulations and
rulings, including but not limited to ERISA and the Code, and all amounts due
thereunder have been paid, except, in each case to the extent that any such
non-compliance would not, nor could reasonably be expected to result in a
Material Adverse Effect on AMHC (as defined in Section 8.5).

                  (l) Compliance With Laws. To the knowledge of AMHC, neither
AMHC nor any of its subsidiaries is in conflict with, or in default or violation
of any law, rule, regulation, order, judgment or decree applicable to AMHC or
any of its subsidiaries or by which AMHC or any of its subsidiaries or any of
their respective properties is bound or affected, in each case except for such
matters which do not have, nor could reasonably be expected to have, a Material
Adverse Effect (as defined in Section 8.5) on AMHC. To the knowledge of AMHC,
(i) no investigation or review by any governmental entity is pending or
threatened against AMHC or any of its subsidiaries, nor has any governmental
entity indicated an intention to conduct the same and (ii) there is no material
judgment, injunction, order or decree binding upon AMHC or any of its
subsidiaries, in each case except for such matters which do not have, nor could
reasonably be expected to have, a Material Adverse Effect (as defined in Section
8.5) on AMHC.

                  (m) Environmental Matters. Except as set forth in Schedule
4.2(m), to the knowledge of AMHC, each of AMHC and its subsidiaries is in
material compliance with all Environmental Laws, which compliance includes, but
is not limited to, the possession by AMHC or its subsidiaries of all permits and
other governmental authorizations required under applicable Environmental Laws,

such non-compliance which does not have, nor could reasonably be expected to
have, a Material Adverse Effect on AMHC (as defined in Section 8.5).

have been required to be set forth or described in the Schedules at such time.

withheld, no supplement or amendment shall be deemed to cure any breach of any
representation or warranty made in this Agreement or have any effect for the
purpose of determining satisfaction of the conditions set forth in Section

of the members of AMHC in accordance with and to the extent required by the
Plan, Articles of Incorporation of AMHC or applicable laws;

                  (b) AMH Approvals. This Agreement and transactions
contemplated hereby shall have been approved and adopted by the requisite vote
of each class of the stockholders of AMH in accordance with and to the extent
required by the Articles of Incorporation of AMH or applicable laws;

                  (c) No Injunctions. No preliminary or permanent injunction or
other order of any federal or state court in the United States which prohibits
the consummation of the Merger shall have been issued and remain in effect;

                  (d) Securities Filings. All required securities filings shall
have become effective and shall be effective at the Effective Time, and no stop
order suspending effectiveness of such filings shall have been issued, and no
action, suit, proceeding or investigation by the SEC or any state securities
commission to suspend the effectiveness thereof shall have been initiated and be
continuing, or, to the knowledge of AMHC or AMH, threatened, and all necessary
approvals under state securities laws relating to the issuance or trading of
AMHC Shares to be issued in connection with the Merger shall have been received;

                  (e) Regulatory Approvals. Approval of any necessary regulatory
bodies shall have been obtained and be in effect, except for approvals which the

                  (f) Listing. The AMHC Shares issuable in the Merger and in
connection with the exercise of Continuing Common Stock Rights shall have been

securities association, subject only to official notice of issuance;

                  (g) Litigation. No order, judgment or decree shall be

of imposing materially adverse conditions deemed to be unreasonable by AMHC or
AMH to, or preventing completion of, the Merger and no suit, action or other
proceeding shall be pending before any court or governmental entity in which it
is sought to restrain or prohibit the Merger or obtain other substantial
monetary or other relief against one or more parties hereto in connection with
this Agreement or the Plan and which AMHC or AMH determines in good faith, based
upon the advice of their respective counsel, makes it inadvisable to proceed
with the Merger because any such suit, action or proceeding has a significant
potential to be resolved in a way so as to deprive the party electing not to
proceed of any of the material benefits to it of the Merger;

                  (h) Non-Governmental Consents. All consents or approvals of
all persons, other than the Iowa Commissioner, Kansas Commissioner, required

indentures entered into by AMHC or AMH, required for or in connection with the
execution, delivery and performance of this Agreement and the consummation of
the Merger shall have been obtained and be in full force and effect, unless the
failure to obtain any such consent or approval is not in the judgment of AMHC
and AMH reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect (as defined in Section 8.5) on AMHC, AMH or the Surviving
Corporation;

Section 8.5) on AMH.

                  (b) Agreements and Covenants. AMH shall have performed or
complied in all material respects with all agreements and covenants required by

         4.4      If Tenant should fail to pay any taxes, assessments or
                  governmental charges required to be paid by it hereunder, in
                  addition to any other remedies provided herein, Landlord may,
                  in its sole discretion, pay such taxes, assessments and
                  governmental charges. Any sums so paid by Landlord shall be
                  deemed to be additional rental owing by Tenant to Landlord and
                  due and payable upon demand as additional rent with interest
                  at the rate of twelve percent (12.00%) from the date of the
                  payment by Landlord.

         4.5      If at any time during the term of the Lease the present method
                  of taxation shall be changed so that, in lieu of the whole or
                  any part of any taxes, assessments, levies or charges levied,
                  assessed or imposed on real estate and the improvements
                  thereon there shall be levied, assessed or imposed on Landlord
                  a capital levy or other tax directly on the rents received
                  from Tenant and/or any assessment, levy or charge measured by
                  or based in whole or in part, upon such rents, then all such
                  taxes, assessments, levies or charges, or the part thereof so
                  measured or based, shall be deemed to be included with the
                  term taxes for the purposes hereof and shall be paid by
                  Tenant.

         4.6      Tenant may contest by appropriate proceedings, the amount,
                  validity or application of any taxes by appropriate
                  proceedings diligently conducted in good faith provided that
                  (a) such proceedings shall suspend the collection thereof, (b)
                  no part of the Leased Property or of any rent would be subject
                  to loss, sale or forfeiture before determination of any
                  contest, (c) Landlord would not be subject to any criminal
                  liability for failure to pay, (d) such proceedings shall not
                  affect the payment of rent hereunder or prevent Tenant from
                  using any Leased Property for its intended purposes, and (e)
                  Tenant shall notify Landlord of any such proceedings at which
                  the amount of contest exceeds $10,000.00 within 20 days after
                  the commencement thereof, and shall describe such proceedings
                  in reasonable detail. Tenant will conduct all such contests in
                  good faith and with due diligence and will, promptly after the
                  determination of such contest, pay and discharge all amounts
                  which shall be determined to be payable therein. In the event
                  Tenant elects to dispute and contest any taxes, it shall
                  provide Landlord with a surety bond in the amount of taxes in
                  dispute.

         4.7      Landlord covenants and agrees that if there shall be any
                  refunds or rebates of the Taxes paid by Tenant, such refunds
                  or rebates shall belong to Tenant. Any refunds received by
                  Landlord shall be deemed trust funds and as such are to be
                  received by Landlord in trust and paid to Tenant forthwith.
                  Tenant will, upon the request of the Landlord, sign any
                  receipts which may be necessary to secure the payment of any
                  such refunds or rebates.

5.0      USE.

         5.1      Use. The Leased Property shall be used and occupied by Tenant
                  only as general office use. Tenant shall not change the use of
                  any Leased Property as set forth above without Landlord's
                  prior written consent, which consent shall not be

                  unreasonably withheld. Tenant will not do or permit any act or
                  thing that is contrary to any legal requirement or insurance
                  requirement, or that impairs the value of any Leased Property
                  or any part thereof or that materially increases the dangers,
                  or poses unreasonable risk of harm, to third parties (in, on
                  or off any Leased Property) arising from activities thereon,
                  or that constitutes a public or private nuisance or waste to
                  any Leased Property or any part thereof. Tenant shall not
                  conduct any activity on any Premises or use any Leased
                  Property in any manner (i) which would cause any Leased
                  Property to become a hazardous waste treatment, storage or
                  disposal facility within the meaning of, or otherwise bring
                  any Leased Property within the ambit of, the Resource
                  Conservation and Recovery Act of 1976 as amended, 42
                  U.S.C.ss.6901 et seq., or any similar state law or local
                  ordinance; (ii) so as to cause a release or threat of release
                  of hazardous waste from any Leased Property within the meaning
                  of, or otherwise bring any Leased Property within the ambit
                  of, the Comprehensive Environmental Response Compensation and
                  Liability Act of 1980 as amended, the Toxic Substance Control
                  Act 15 U.S.C.ss. 2601, et seq. and the Federal Hazardous
                  Materials Transportation Act 49 U.S.C.ss.1801 et seq., or any
                  similar state law or local ordinance or any other
                  environmental law; or (iii) so as to cause a discharge of
                  pollutants or effluents into any water source or system, or
                  the discharge into the air of any emissions, which would
                  require a permit under the Federal Water Pollution Control
                  Act, 33 U.S.C.ss.1251, et seq., or the Clean Air Act, 42
                  U.S.C.ss.1857, et seq., or any similar state or local
                  ordinance.

         5.2      Compliance with the Law. Tenant shall, at Tenant's expense,
                  comply promptly with all applicable statutes, ordinances,
                  rules, regulations, orders and requirements in effect during
                  the term hereof, regarding the use by Tenant of any Leased
                  Property. Tenant shall not use or permit the use of any Leased
                  Property in any manner that will tend to create waste or a
                  nuisance, or, otherwise expose Landlord or any Leased Property
                  to any liability.

         5.3      Condition of Leased Property. Tenant hereby accepts all of the
                  Leased Property in their condition as of the date of the
                  possession hereunder, subject to all applicable zoning,
                  municipal, county and state laws, ordinances, and regulations
                  governing and regulating the use of any Leased Property, and
                  accepts this Lease subject thereto and to all matters
                  disclosed thereby, and by any exhibits attached hereto. Tenant
                  acknowledges that neither the Landlord nor Landlord's agent
                  has made any representation or warranty as to the suitability
                  of any Leased Property for the conduct of the Tenant's
                  business.

         5.4      Tenant's Covenants and Indemnity. Tenant shall not dispose of
                  or otherwise allow the release of any hazardous waste or
                  materials in, on, or under the Premises, or any adjacent
                  property or in any improvements placed on the Premises. Tenant
                  represents and warrants to Landlord that Tenant's intended use
                  of any Leased Property does not involve the use, production,
                  disposal or bringing onto any Premises of any hazardous waste
                  or materials. Tenant shall promptly comply with all statutes,
                  regulations and ordinances, and with all orders, decrees

                  waste or materials, in, on, or under any Leased Property or
                  any adjacent property, or incorporated in any improvements, at
                  Tenant's expense.

                  Whether or not Tenant has actual knowledge of the release of
                  hazardous waste or materials in, on, or under any Leased
                  Property or any adjacent property as the result of Tenant's
                  use of any Leased Property, Tenant shall reimburse Landlord
                  for the full amount of all costs and expenses incurred by
                  Landlord in connection with such compliance activities, and
                  such obligation shall continue even after the termination of
                  this Lease. Tenant shall notify Landlord immediately of any
                  release of any hazardous waste or materials in, on or under
                  any Leased Property.

                  Tenant shall indemnify, defend and hold Landlord harmless from
                  and against any and all claims, damages, demands, losses,
                  liens, liabilities, obligations, fines, penalties, charges,

                  proceedings and costs and expenses (including, without
                  limitation, attorneys' fees and disbursements) which may be
                  imposed on, incurred or paid by, or asserted against Landlord
                  or any Leased Property by reason of, or in connection with (i)
                  any misrepresentation or breach of warranty, or (ii) the acts
                  or omissions of Tenant, or any sublessee or other person for
                  whom Tenant would otherwise be liable, resulting in the
                  release of any hazardous waste or materials, or (iii) arising
                  directly or indirectly from or out of or in any way connected
                  to Tenant's use, storage, ownership, possession, or control of
                  hazardous substances in, on or under any Leased Property which
                  directly or indirectly result in the Leased Property or any
                  other property becoming contaminated with hazardous
                  substances. Tenant hereby agrees upon notification to clean up
                  from any Leased Property or any other property any
                  contamination caused by its activity, including, without
                  limitation, use, storage, ownership, possession or control of
                  hazardous substances in, on or under any Leased Property,
                  including, without limitations, any remedial action required
                  by applicable governmental authorities. Tenant further
                  acknowledges that it will be solely responsible for all costs
                  and expenses relating to the clean up of hazardous substances
                  from any Leased Property or any other properties which become
                  contaminated with hazardous substances as a result of Tenant's
                  activities in, on or under any Leased Property.

                  may enter into a property management contract with a third
                  party or entity related to Landlord for the management of the

                  not exceed $50,000.00 annually. Tenant shall be responsible to

                  for actual cost of on-site maintenance personnel who are not
                  employees of Tenant.

         7.2      Maintenance and Repairs. Tenant shall at its sole cost and
                  expense keep and maintain all Leased Property, including
                  sidewalks, landscaping and driveways located on the Premises,
                  in good working order and condition and repair, and shall
                  suffer no waste with respect thereto. Tenant shall at its sole
                  cost and expense make all needed repairs to and replacements
                  of the Leased Property, interior and exterior, structural and
                  nonstructural, ordinary and extraordinary, including but not
                  limited to any roof, air conditioning and heating systems,
                  replacements or cracked or broken glass, repair of parking
                  areas and driveways, and shall keep the plumbing units, pipes
                  and connections free from obstruction and protected against
                  ice and freezing. Landlord has no responsibility to maintain
                  or pay for any part of the maintenance or replacement of the
                  Leased Property.

         7.3      Surrender. On the last day of the term hereof, or on any
                  sooner termination, Tenant shall surrender the Leased Property
                  to Landlord in good condition, broom clean, ordinary wear and
                  tear excepted. Tenant shall repair any damage to the Leased
                  Property caused by the removal of Tenant's Equipment pursuant

                  of any kind or type, the repair or replacement (but only to

                  all heating, air conditioning, and ventilating equipment.

         7.4      Landlord's Rights. If Tenant fails to perform Tenant's
                  obligations under any of the provisions of this Section 7,
                  Landlord shall give Tenant written notice to do such acts as
                  are reasonably required to maintain any Leased Property in
                  good order and condition. If, within thirty (30) days of such
                  notice, Tenant fails to commence to do the work and diligently
                  prosecute it to completion, then Landlord shall have the
                  right, (but not the obligation) at Tenant's expense to take
                  such action or expend such funds necessary (i) to prevent
                  immediate physical deterioration to the Premises or (ii) to

                  installations on or about any Premises without the express
                  written consent of the Landlord; provided, however, that the

                  include ducting, power plants, space heaters, conduit, and

                  not be unreasonably withheld.

         (c)      All alterations, changes, additions, improvements, and utility
                  installations (whether or not such utility installations

         (d)      Landlord shall be deemed to have given its consent to a
                  request pursuant to this Section 7.4 if it fails to respond to
                  Tenant's written request within fifteen (15) days after
                  receipt thereof and if the request states on its face that
                  failure to respond in a fifteen (15) day period will be deemed
                  to be a consent.

8.0      ENTRY BY LANDLORD.

         Landlord and Landlord's agents, shall have the right on reasonable

         law, the right, but by no means the obligation, to cause the lien to be
         released by such means as it shall deem proper, including payment of
         the claim giving rise to the lien. All such sums paid by Landlord and

                  notice from Landlord, shall defend same at Tenant's expense by
                  counsel reasonably satisfactory to Landlord. However, Tenant
                  shall not be liable for any damage or injury occasioned by the
                  negligence or intentional acts of Landlord or its designated
                  agents, or employees.

                  acts or gross negligence of the Landlord, its agents and

                  damage which may be sustained by the person, goods, wares,
                  merchandise, or property of the Tenant, or by any agent or
                  other person claiming by or under Tenant which might be caused
                  by or resulting from fire, steam, electricity, gas, water, or
                  rain, which may leak or flow from or into any part of

                  results from conditions arising in, on or under any Building
                  or Premises or from other sources. Landlord shall not be
                  liable for any damages arising from any act or neglect of any
                  other tenant (if any) of any Building or Premises. Tenant
                  shall defend, indemnify and hold harmless Landlord from and
                  against any and all claims by any person which may arise from
                  the matters mentioned in this Section 10.2 except for
                  intentional acts or negligence of the Landlord, its agents and

                  insuring Landlord and Tenant against any liability arising out
                  of the ownership, use, occupancy, or maintenance of any Leased
                  Property. Such insurance shall at all times be in an amount of
                  not less than $2,000,000.00. The limits of such insurance
                  shall not limit the liability of the Tenant. All insurance

                  and amounts of such insurance with loss payable clauses
                  satisfactory to Landlord, provided that in the event Tenant
                  fails to procure and maintain such insurance, Landlord may
                  (but shall not be required to), procure same at Tenant's
                  expense after ten (10) days prior written notice. No such

                  or other modification except after thirty (30) days prior
                  written notice to Landlord by the insurer. All such policies
                  shall be written as primary policies, not contributing with
                  and not in excess of coverages which the Landlord may carry.
                  Tenant shall, within twenty (20) days prior to the expiration
                  of such policies, furnish Landlord with renewals or binders or
                  Landlord may order such insurance and charge the cost to the
                  Tenant, which amounts shall be payable by Tenant on demand.
                  Tenant shall have the right to provide such insurance coverage
                  pursuant to blanket policies which the Tenant may have in
                  force, provided such blanket policies expressly afford
                  coverage of any Leased Property and to Landlord as is required
                  by this Lease.

         11.2     Property Insurance. Landlord shall, at Tenant's expense,

                  Lease, the policy or policies of insurance covering loss or
                  damage to any Leased Property in the amount of the full
                  replacement value thereof, and providing protection against
                  all perils included within the classification of fire,
                  extended coverage, vandalism, malicious mischief, sprinkler

                  Property is in a flood plain), and special extended peril (all
                  risk). All such policies shall be written as primary policies,
                  not contributing with and not in excess of coverages which the
                  Landlord may carry. Landlord shall order such insurance and
                  charge the cost to the Tenant, which amounts shall be payable
                  by Tenant on demand. If


                                       10
<PAGE>   11

                  Tenant determines that the premium cost is too high, Tenant
                  may deliver quotes from three other insurer of similar or
                  better Best rating for similar coverage and provided the
                  quotes show more than a 10% reduction in premium rate,
                  Landlord will select one of the three insurers to provide the
                  insurance for the Leased Premises. Such insurance shall
                  provide for payment of losses thereunder to Landlord or the
                  holder of a first mortgage or deed of trust on any of the
                  Leased Property. Any loss proceeds shall be made available for
                  the purposes of replacing or rebuilding the pertinent Leased
                  Property if required under Section 12 and in which event, such
                  funds shall be segregated from the general funds of Landlord.

         11.3     Waiver of Subrogation. Landlord and Tenant shall waive any and
                  all rights of recovery against the other or against the
                  officers, employees, agents and representatives of the other,
                  on account of loss or damage occasioned to such waiving party
                  or its property or the property of others under its control
                  caused by fire or any of the extended coverage risks described
                  above to the extent that such loss or damage is insured.
                  Landlord and/or Tenant shall give notice to the insurance
                  carrier or carriers involved that the foregoing mutual Waiver
                  of Subrogation option is contained in this Lease. The waivers
                  provided for in this Section 11.3 shall be applicable and
                  effective only in the event such waivers are obtainable from
                  the insurance carriers concerned.

12.0     DAMAGE TO PREMISES.

         12.1     Partial or Total Damage -Insurance Available. In the event of
                  damage causing a partial or total destruction of the Building
                  during the term of this Lease and there is made available to
                  the Landlord, pursuant to Section 11.0 above, insurance
                  proceeds for such damage, Landlord shall utilize all such
                  insurance proceeds and cause the Building to be promptly
                  repaired to the condition existing immediately prior to such
                  damage, with this Lease to continue in full force and effect.
                  Tenant shall deposit with Landlord or make available to
                  Landlord only that amount equal to the deductible provided
                  under said insurance contract within ten (10) days after
                  notice to Tenant by Landlord. Provided, however, if Landlord
                  has not begun reconstruction or repairs within thirty (30)
                  days after the later of (i) receipt of available insurance
                  proceeds or (ii) receipt of the deductible payment, or it is
                  not reasonably anticipated that such repair or reconstruction
                  can be completed within a 180-day period after commencement or
                  reconstruction, Tenant may terminate this Lease by written
                  notice to Landlord along with the insurance deductible.

                  If after commencement of construction the Building is not
                  completed and ready for occupancy within 180 days after the
                  commencement of construction, subject to Force Majeure causes,
                  Tenant may terminate this Lease by written notice to the
                  Landlord. For purposes hereof, a Force Majeure cause shall be
                  an act of God, weather, earthquake, strike, insurrection, war
                  or other event outside the control of Landlord, during which
                  period the 180-day period referenced above shall be abated.

<PAGE>   12

         12.2     Repair Not Permitted. In the event that the Building may not
                  be repaired herein under applicable laws and regulations
                  notwithstanding the availability of insurance proceeds, this
                  Lease shall be terminated as to such Leased Property effective
                  with the date of the damage occurrence, and Landlord shall be
                  entitled to retain the insurance proceeds pertaining to the
                  Leased Property and receive from Tenant the amount of the
                  insurance deductible.

         12.3     Damage to Building or Personal Property During Last Two Years
                  of Term. In the event of any total or partial destruction to
                  the Building occurring during the last two (2) year period of
                  the term of this Lease (or any extension thereof), and
                  notwithstanding the provisions of Sections 12.1 above,
                  Landlord or Tenant shall have the right for the longer of (i)
                  a period of sixty (60) days following the event giving rise to
                  the casualty or damage, or (ii) the period of fifteen (15)
                  days following the receipt of insurance proceeds to terminate
                  this Lease as to such Leased Property. In the event of such
                  termination, Landlord shall be entitled to retain the
                  insurance proceeds and receive from Tenant the amount of the
                  insurance deductible. This Section shall not apply to a
                  casualty during any period in which the remaining Lease Term
                  (including any properly exercised renewal options) is greater
                  than two (2) years.

13.0     CONDEMNATION.

         If all, or a substantial portion of any Leased Property shall be taken
         or appropriated for public or quasi-public use by the right of eminent
         domain, (with or without litigation), or transferred by agreement in
         connection with such public or quasi-public use, either Landlord or
         Tenant shall have the right at is option (exercisable within thirty
         (30) days of the receipt of notice of such taking) to terminate this
         Lease as to such Leased Property as of the date possession is taken by
         the condemning authority. A substantial portion of the Leased Property
         shall be deemed to be taken or appropriated if more than twenty percent
         (20.0%) of the Building is subject to such taking. If all or a
         substantial portion of the parking shall be taken, Landlord shall
         immediately procure equivalent substitute parking acceptable to Tenant,
         which acceptance shall not be unreasonably withheld. Absent acceptance,
         Tenant shall have the right to terminate this Lease. No award for any
         partial or entire taking shall be apportioned, and except as provided
         in the next sentence, Tenant hereby assigns to Landlord any award which
         may be made in such taking appropriation, or condemnation, together
         with any and all rights of Tenant now or hereafter arising in such
         award. Landlord has no interest, however, in any award made to Tenant
         for the taking of Equipment belonging to Tenant; or for the
         interruption of or damage to Tenant's business, or to Tenant's
         unamortized cost of leasehold improvements. Any award to the Landlord
         by reason of such partial taking shall be made available for
         reconstruction, should the Tenant so elect, and shall be segregated
         from the Landlord's general funds. No temporary taking of any Leased
         Property and/or of the Tenant's rights therein, or under this Lease,
         shall terminate this Lease as to such Leased Property or give Tenant
         any right to any abatement of rent. Provided, however, if it is
         reasonably anticipated that such temporary taking will extend for any
         greater than 180 days, or if such temporary taking actually extends
         beyond such 180 period, subject to Force Majeure


                                       12
<PAGE>   13
         causes, Tenant may, by written notice to Landlord, terminate this
         Lease. Any award made for such temporary taking shall belong entirely
         to Tenant unless Tenant terminates this Lease, in which event the award
         shall belong entirely to Landlord.

14.0     ASSIGNMENT AND SUBLETTING.

         14.1     Landlord's Consent Required. Tenant shall not assign,
                  transfer, mortgage, pledge, hypothecate, or encumber this
                  Lease or any interest therein, nor permit such assignment by
                  operation of law, and shall not sublet any Leased Property or
                  any part thereof, without the prior express written consent of
                  the Landlord, which consent shall not be unreasonably
                  withheld. Any attempt to do so without such consent being in
                  hand, shall be wholly void and shall constitute a breach of
                  this Lease.

         14.2     No Release of Tenant. No consent by Landlord to any assignment
                  or subletting by Tenant shall relieve Tenant of any
                  obligations to be performed by Tenant under this Lease,
                  whether occurring before or after such assignment or
                  subletting. The consent by Landlord to any assignment or
                  subletting shall not relieve Tenant from the obligation to
                  obtain Landlord's express written consent to any other
                  assignment or subletting. The acceptance of any rent by
                  Landlord from any person shall not be deemed to be a waiver by
                  Landlord of any provision of this Lease, or to be deemed a
                  consent to any assignment, subletting, or other transfer.

         14.3     By Landlord. This Lease shall be fully assignable by Landlord
                  or its assigns.

         14.4     Permitted Assignments. Notwithstanding anything to the
                  contrary in this Lease, Tenant may assign the Lease without
                  Landlord's consent to:

                  (a)      a parent or subsidiary corporation of Tenant, or

                  (b)      the surviving entity in the event of the merger,
                           consolidation or acquisition of Tenant, or

                  (c)      an entity which purchases all or substantially all of
                           Tenant's assets, or

                  (d)      to any person or entity which purchases all or
                           substantially all of the stock of Tenants

                  provided that in (a) through (d) above, the proposed assignee
                  meets each of the following criteria:

                           (i)      The proposed assignee has a net worth (at
                                    the time of assignment) of at least
                                    $150,000,000.00.

                           (ii)     The proposed assignee's use of the Premises
                                    conforms to the permitted use under this
                                    Lease.

<PAGE>   14

                           (iii)    Landlord (or any of its affiliates) has not
                                    had problems (including, but not limited to,
                                    material defaults, late payments,
                                    bankruptcies, court cases, maintenance
                                    concerns, or other property management
                                    problems) with the proposed assignee.

15.0     SUBORDINATION

         15.1     Subordination. At Landlord's option, this Lease shall be
                  subject and subordinate to all ground or underlying leases
                  hereinafter executed affecting any Leased Property, and to the
                  lien of any mortgages or deeds of trust in any amount or
                  amounts whatsoever now or hereafter placed on or against the
                  land or improvements or either thereof, of which the Premises
                  are a part, without the necessity of the execution and
                  delivery of any further instruments, on the part of the
                  Tenant, to effectuate such subordination. If any mortgagee,
                  trustee, or ground lessor shall elect to have this Lease prior
                  to the lien of its mortgage deed of trust or ground lease, and
                  shall give written notice thereof to Tenant, this Lease shall
                  be deemed prior to such mortgage, deed of trust or ground
                  lease, on the date of the recording thereof.

         15.2     Subordination Agreements. Tenant covenants and agrees to
                  execute and deliver upon demand, without charge, such further
                  instruments evidencing such subordination of this Lease to
                  such ground or underlying leases and to the lien of any such
                  mortgages or deeds of trust as may be required by Landlord.

         15.3     Quiet Enjoyment. Landlord covenants and agrees with Tenant
                  that upon Tenant paying rent and other monetary sums due under
                  this Lease, performing its covenants and conditions of the
                  Lease and upon recognizing any subsequent lessor under a
                  ground or underlying lease or any purchaser as Landlord,
                  Tenant shall and may peaceably and quietly have, hold, and
                  enjoy the Leased Property for the term of the Lease as against
                  any adverse claim of Landlord or any party claiming under
                  Landlord subject, however, to the terms of the Lease.

         15.4     Attornment. In the event any proceedings are brought for
                  default under any ground or underlying lease, or in the event
                  of foreclosure or the exercise of a power of sale under any
                  mortgage or deed or trust made by Landlord covering any Leased
                  Property, the Tenant shall attorn to the lessor under the
                  ground or underlying lease or the purchaser upon any such
                  foreclosure, or sale, and recognize such lessor or purchaser
                  as the Landlord under this Lease, provided said lessor or
                  purchaser expressly agrees in writing to be bound by the terms
                  of this Lease.

         15.5     Non-Disturbance. Tenant's agreement to subordinate or attorn
                  pursuant to Section 15.1 and 15.4 is expressly contingent upon
                  Tenant receiving a commercially reasonable and acceptable
                  non-disturbance agreement at no cost to Tenant.

16.0     DEFAULT, REMEDIES

         16.1     Event of Default. The occurrence of any of the following shall
                  constitute a material default and breach of this lease by
                  Tenant:

                  (a)      Any failure by Tenant to pay the rent or any other
                           monetary sums required to be paid hereunder (where
                           such failure continues for five (5) days after
                           written notice by Landlord to Tenant);

                  (b)      The abandonment or vacation of any Leased Property by
                           the Tenant;

                  (c)      A failure by Tenant to observe and perform any other
                           provision of this Lease to be observed or performed
                           by Tenant, where such failure continues for thirty
                           (30) days after written notice thereof by the
                           Landlord to the Tenant. However, if the nature of the
                           default is such that the default cannot be reasonably
                           cured within the thirty (30) day period, Tenant shall
                           not be deemed to be in default if Tenant shall within
                           such period of time commence such cure and thereafter
                           diligently prosecute the same to completion;

                  (d)      The making by Tenant of any general assignment or
                           general arrangement for the benefit of creditors; the
                           filing by or against Tenant of a petition to have
                           Tenant adjudged a bankrupt, or of a petition for
                           reorganization or arrangement under any law relating
                           to bankruptcy; the appointment of a trustee or
                           receiver to take possession of substantially all of
                           the Tenant's assets located at any Premises or of
                           Tenant's interest in this Lease where possession is
                           not restored to Tenant within thirty (30) days; or
                           the attachment, execution or other judicial seizure
                           of substantially all of Tenant's assets located at
                           any Premises or of Tenant's interest in this Lease,
                           where such seizure is not discharged within thirty
                           (30) days; and

         16.2     Remedies. Upon the occurrence of any Event of Default
                  described in Paragraph 16.1 and at any time thereafter so long
                  as the same shall be continuing, Landlord may, at its option,
                  by notice to Tenant do one or more of the following, as
                  Landlord in its sole discretion shall determine:

                  (a)      Landlord may, by notice to Tenant, terminate this
                           Lease as of the date specified in such notice;
                           however, (A) no reletting, reentry or taking of
                           possession of any or all of the Property by Landlord
                           will be construed as an election on Landlord's part
                           to terminate this Lease unless a written notice of
                           such intention is given to Tenant, (B)
                           notwithstanding any reletting, reentry or taking of
                           possession, Landlord may at any time thereafter elect
                           to terminate this Lease with respect to any or all of
                           the Leased Property, and (C) no act or thing done by
                           Landlord or any of its agents, representatives or
                           employees and no agreement accepting a


                                       15
<PAGE>   16

                           surrender of any or all of the Leased Property shall
                           be valid unless the same be made in writing and
                           executed by Landlord;

                  (b)      Landlord may (i) demand that Tenat, and Tenant shall
                           upon the written demand of Landlord, return the
                           Leased Property promptly to Landlord in the manner
                           and condition as if the Leased Property were being
                           returned at the end of the Term, and Landlord shall
                           not be liable for the reimbursement of Tenant for any
                           costs and expenses incurred by Tenant in connection
                           therewith, and (ii) without prejudice to any other
                           remedy which Landlord may have for possession of the
                           Leased Property, enter upon the Leased Property and
                           take immediate possession of (to the exclusion of
                           Tenet) the Leased Property and expel or remove Tenant
                           and any other person who may be occupying the same,
                           by summary proceedings or otherwise, all without
                           liability to Landlord for or by reason of such entry
                           or taking of possession, whether for the restoration
                           of damage to property caused by such taking or
                           otherwise and, in addition to Landlord's other
                           damages, Tenant shall be responsible for the
                           reasonably necessary costs and expenses of reletting,
                           including without limitation, brokers fees, tenant
                           improvements and inducements for new tenants,
                           security costs, expenses of the lender, prepayment or
                           other penalties under any note or mortgage and the
                           costs of any repairs made by Landlord.

                  (c)      Except as Landlord may otherwise be required by law,
                           Landlord may hold, keep idle or lease to others the
                           property as Landlord in its sole discretion may
                           determine, free and clear of any rights of Tenant and
                           without any duty to account to Tenant with respect to
                           such action or inaction or for any proceeds with
                           respect to such action or inaction, except that
                           Tenant's obligation to pay base rent from and after
                           the occurrence of an Event of Default shall be
                           reduced by the net proceeds, if any, received by
                           Landlord from leasing the Leased Property to any
                           person, or allowing any person to use the Leased
                           Property, other than Tenant for the same periods or
                           any portion thereof;

                  (d)      Landlord may retain and apply against Landlord's
                           damages all sums which Landlord would, absent such
                           Event of Default, be required to pay to, or turn over
                           to, Tenant pursuant to the terms of this Lease; or

                  (e)      Landlord may exercise any other right or remedy that
                           may be available to it by law or in equity, or
                           proceed by appropriate court action (legal or
                           equitable) to enforce the terms hereof or to recover
                           damages for the breach hereof including without
                           limitation, the right to sue for and collect the
                           present value of all future base rent from date of
                           termination for the balance of the Term (if the Lease
                           had not been terminated) discounted monthly at the
                           annual rate then in effect as the Discount Rate of
                           the Federal Reserve Bank of New York. Separate suits
                           may be brought to collect any such damages for any
                           period or periods with respect to which


                                       16
<PAGE>   17

                           rent shall have accrued, and such suits shall not in
                           any manner prejudice Landlord's right to collect any
                           such damages for any subsequent periods, or Landlord
                           may defer any such suit until after the expiration of
                           the base Term or the then current renewal Term, in
                           which event such suit shall be deemed not to have
                           accrued until the expiration of the base Term, or the
                           then current renewal Term.

         16.3     Late Charges. Tenant hereby acknowledges that late payment by
                  Tenant to Landlord of rent and other sums due hereunder will
                  cause Landlord to incur costs not contemplated by this Lease,
                  the exact amount of which will be difficult to ascertain. Such
                  costs include, but are not limited to, processing and
                  accounting charges, and late charges which may be imposed on
                  Landlord by the terms of any mortgage or deed of trust
                  covering any Leased Property. Accordingly, if any installment
                  of rent or any other sum due from Tenant shall not be received
                  by Landlord or Landlord's designee within five (5) days after
                  such amount shall be due, Tenant shall pay to Landlord a late
                  charge equal to five percent (5.00%) of such overdue amount.
                  The parties hereby agree that such late charge represents a
                  fair and reasonable estimate of the cost Landlord will incur
                  by reason of late payment by Tenant.

         16.4     Default by Landlord. Landlord shall not be in default unless
                  Landlord fails to perform obligations required of Landlord
                  within a reasonable time, but in no event later than thirty
                  (30) days after written notice by Tenant to Landlord and to
                  the holder of any first mortgage or deed of trust covering the
                  Premises, whose name and address shall have been furnished to
                  Tenant in writing, specifying wherein Landlord has failed to
                  perform such obligation, provided, however that if the nature
                  of Landlord's obligation is such that more than thirty (30)
                  days are required for performance, then Landlord shall not be
                  in default if Landlord commences performance within such
                  thirty (30) day period and thereafter diligently prosecutes
                  same to completion. Tenant agrees that any such mortgagee or
                  deed of trust holder shall have the right to cure such default
                  on behalf of Landlord within thirty (30) calendar days after
                  receipt of such notice.

         17.1     Estoppel Certificate.

                  (a)      Tenant shall at any time upon not less than twenty
                           (20) days prior written notice from Landlord,
                           execute, and deliver to Landlord a statement in
                           writing (i) certifying that this Lease is unmodified
                           and in full force and effect (or, if modified,
                           stating the nature of such modification and
                           certifying that this Lease, as so modified, is in
                           full force and effect), and the date to which the
                           rent and other charges are paid in advance, if any,
                           and (ii) acknowledging that there are not, to
                           Tenant's knowledge, any uncured defaults on the part
                           of Landlord hereunder, or specifying such defaults if
                           any are claimed. Any such statement may be
                           conclusively

                           relied upon by any prospective purchaser or
                           encumbrancer of any Leased Property.

                  (b)      Tenant's failure to deliver such statement within
                           such time shall be conclusive upon Tenant (i) that
                           this Lease is in full force and effect, without
                           modification except as may be represented by
                           Landlord, (ii) that there are no uncured defaults in
                           Landlord's performance, and (iii) that not more than
                           one month's rent has been paid in advance.

                  (c)      Landlord shall execute such estoppel certificates,
                           upon twenty (20) days written notice from Tenant, as
                           Tenant may request from time to time. Landlord's
                           failure to deliver such statement within such time
                           shall be conclusive upon Landlord (i) that this Lease
                           is in full force and effect, without modification
                           except as may be represented by Tenant, (ii) that
                           there are no uncured defaults in Tenant's performance
                           and (iii) that not more than one month's rent has
                           been paid in advance.

         17.2     Transfer of Landlord's Interest.

                  (a)      In the event of a bona fide sale or conveyance by
                           Landlord of Landlord's interest in any Leased
                           Property or in any other property in which any
                           Premises may be a part, other than a transfer for
                           security purposes only, if Landlord is not in default
                           under any provisions of this Lease, Landlord shall be
                           relieved from and after the date specified in any
                           such notice of transfer of all obligations and
                           liabilities accruing thereafter on the part of the
                           Landlord with respect to the transferred Leased
                           Property, provided that any funds in the hands of
                           Landlord at the time of transfer in which Tenant has
                           an interest, shall be delivered to the successor of
                           the Landlord and provided Landlord's assignee assumes
                           all such obligations. This Lease shall not be
                           affected by any such sale and Tenant agrees to attorn
                           to the purchaser or assignee provided all Landlord's
                           obligations hereunder are assumed in writing by the
                           transferee.

                  (b)      Tenant acknowledges notice from Landlord of its
                           intent to enter into a Purchase Agreement for the
                           sale of the subject property to William C. Knapp as
                           Trustee of the William C. Knapp Revocable Trust or
                           its assigns. Should said sale be completed, Landlord
                           acknowledges herein its agreement to pay to said
                           Purchaser the sum of $1,984,162.00 payable in the
                           event that Tenant does not exercise its first option
                           to renew this Lease for the first additional five (5)
                           year term for any reason other than default of
                           Landlord or Landlord's election to terminate the
                           Lease under the provisions of Paragraph 12.0.
                           However, should this Lease be terminated by Tenant
                           under the provisions relating to condemnation found
                           in Paragraph 13.0 herein, Tenant's payment required
                           herein shall be reduced by an amount equal to the
                           difference between $5,200,000.00 purchase price paid
                           by Landlord and the amount received from the
                           condemning


                                       18

                           authority. No reduction shall be made in the event of
                           a casualty loss if Tenant elects to terminate this
                           Lease pursuant to the provisions of Paragraph 12.0 or
                           if repairs are not permitted pursuant to the
                           application of Paragraph 12.2. This payment has been
                           calculated and attributed to asbestos abatement
                           costs. Payment is due on date of termination.

         17.3     Captions; Attachment; Defined Terms.

                  (a)      Captions of the paragraphs of this Lease are for
                           convenience only and shall not be deemed to be
                           relevant in resolving any question of interpretation
                           or construction of any section of this Lease.

                  (b)      Exhibits attached hereto, and addendums and schedules
                           initialed by the parties, are deemed by attachment to
                           constitute part of this Lease and are incorporated
                           herein.

         17.4     Entire Agreement. This instrument along with any exhibits and
                  attachments hereto constitutes the entire agreement between
                  Landlord and Tenant relative to the Leased Property. This
                  agreement and the exhibits and attachments may be altered,
                  amended, or revoked only by an instrument in writing signed by
                  both Landlord and Tenant. Landlord and Tenant hereby agree
                  that all prior or contemporaneous oral agreements between and
                  among themselves and their agents or representatives relating
                  to the leasing of any Leased Property are merged into or
                  revoked by this agreement.

         17.5     Severability. The invalidity of any provision of this Lease,
                  as determined by a court of competent jurisdiction, shall in
                  no way affect the validity of any other provision hereof.

         17.6     Time; Joint and Several Liability. Time is of the essence of
                  this Lease in each and every provision hereof. All the terms,
                  covenants, and conditions contained in this Lease to be
                  performed by either party, if such party shall consist of more
                  than one person or organization, shall be deemed to be joint
                  and several, and all rights and remedies of the parties shall
                  be cumulative and non-exclusive of any other remedy at law or
                  in equity.

         17.7     Waiver. No waiver by Landlord of any provision hereof shall be
                  deemed a waiver of any other provision hereof or of any
                  subsequent breach by Tenant of the same or any other
                  provision. Landlord's consent to or approval of any act shall
                  not be deemed to render unnecessary the obtaining of
                  Landlord's express written consent to or approval of any
                  subsequent act by the Tenant. The acceptance of rent hereunder
                  by Landlord shall not be a waiver of any succeeding breach by
                  Tenant of any provision hereof, other than the failure of
                  Tenant to pay the particular rent so accepted, regardless of
                  Landlord's knowledge of such succeeding breach at the time of
                  acceptance of such rent.

         17.8     Surrender of Premises. The voluntary or other surrender of
                  this Lease by the Tenant, or mutual cancellation thereof,
                  shall not work a merger, and shall, at the option of Landlord,
                  terminate all or any existing subleases or subtenancies, or
                  may, at the option of Landlord, operate as an assignment to it
                  of any or all such subleases or subtenancies.

         17.9     Holding Over. If Tenant remains in possession of all or any
                  part of any Leased Property after the expiration of the term
                  of this Lease, with or without the express or implied consent
                  of the Landlord, such tenancy shall be from month to month
                  only, and not a renewal of this Lease or an extension for any
                  further term. In such case, rent and other monetary sums due
                  hereunder shall be payable in the amount and at the time
                  specified in this Lease and such month-to-month tenancy shall
                  be subject to every other term, covenant, and agreement
                  contained herein. Base rent shall increase to 125% of the most
                  recent base rent of the preceding term.

         17.10    Signs.

                  (a)      Tenant shall have the right to erect such signs as it
                           shall elect, all in accordance with legal
                           requirements.

                  (b)      Any such signs described above shall be removed at
                           the expiration or earlier termination of the Lease at
                           Tenant's expense and Tenant shall repair any damage
                           to any Leased Property resulting from such removal.
                           If Tenant fails to do so, Landlord may cause such
                           removal and repair on Tenant's behalf at Tenant's
                           expense.

         17.11    Reasonable Consent. Except as limited elsewhere in this Lease,
                  wherever in this Lease Landlord and/or Tenant is required to
                  give its consent or approval to any action on the part of the
                  other, such consent or approval shall not be unreasonably
                  withheld or delayed. In the event of failure to give any such
                  consent, the other party shall be entitled to specific
                  performance of law and shall have such other remedies as are
                  reserved to it under this Lease.

         17.12    Interest on Past-Due Obligations. Except as expressly herein
                  provided, any amount due to Landlord not paid when due shall
                  bear interest at twelve percent (12.00%) per annum from the
                  due date. Payment of such interest shall not excuse or cure
                  any default by Tenant under this Lease. Payment of such
                  interest is in addition to the late charge specified in
                  Section 16.3 of this Lease.

         17.13    Recording. Tenant shall not record this Lease without
                  Landlord's prior express written consent. Landlord and Tenant
                  shall, at the request of either and at Tenant's expense,
                  execute and record a short form or memorandum of Lease.

         17.14    Costs of Suit.

                  (a)      If Tenant or Landlord shall bring any action for any
                           relief against the other, declaratory or otherwise,
                           arising out of this Lease, including any suit by
                           Landlord for the recovery of rent or possession of
                           any Leased Property, the prevailing party shall be
                           entitled to an award of its reasonable attorneys'
                           fees and costs. Such fees and costs shall include
                           those fees and costs incurred at trial, on appeal, or
                           in any bankruptcy proceeding.

                  (b)      Should Landlord, without fault on Landlord's part, be
                           made a party to any litigation instituted by Tenant
                           or any third party against Tenant, or by or against
                           any person holding under or using any Leased Property
                           by license of Tenant, or for the foreclosure of any
                           lien for labor, material furnished to or for Tenant
                           or any such other person or otherwise arising out of
                           or resulting from any act or transaction of Tenant,
                           or of any such person, Tenant covenants to defend,
                           indemnify, and hold Landlord harmless from any
                           judgment rendered against Landlord or any Leased
                           Property, or any part thereof, and all costs and
                           expenses, including reasonable attorney fees,
                           incurred by Landlord in or in connection with such
                           litigation.

         17.15    Binding Effect; Choice of Law. The parties hereto agree that
                  all provisions hereof are to be construed as both covenants,
                  and conditions as though the words importing such covenants
                  and conditions were used in each separate paragraph hereof.
                  Subject to any provisions hereof restricting assignment or
                  subletting by the Tenant, all of the provisions hereof shall
                  bind and inure to the benefit of the parties hereto, their
                  respective heirs, legal representative, assigns, and
                  successors. This Lease shall be governed by the laws of the
                  State of Iowa.

         17.16    Waiver of Jury Trial. EACH OF THE PARTIES HERETO KNOWINGLY,
                  VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHTS IT MAY HAVE TO
                  A TRIAL BY JURY IN RESPECT OF ANY LITIGATION ARISING OUT OF,
                  UNDER, OR IN CONNECTION WITH THIS LEASE OR ANY EXHIBIT HERETO,
                  OR ANY COURSE OF CONDUCT, COURSE OF DEALING OR STATEMENTS
                  (WHETHER VERBAL OR WRITTEN) MADE BY THE PARTIES HEREIN.

         17.17    Corporate Authority. If Tenant is a corporation, each
                  individual executing this Lease on behalf of said corporation
                  represents and warrants that he is duly authorized to execute
                  and deliver this Lease on behalf of said corporation in
                  accordance with a duly adopted resolution of the Board of
                  Directors of said corporation, and that this Lease is binding
                  upon said corporation in accordance with its terms.

         17.18    Representation of Landlord. Landlord represents and warrants
                  that (i) it holds fee or leasehold title to the Leased
                  Property subject to the Lease and has full power and authority
                  to enter into this Lease; and (ii) each individual executing

such consent not to be unreasonably withheld.

         Section 1.04. The services provided by the Services Provider under this
Agreement shall be performed in a professional and commercially reasonable
manner consistent with industry standards and in accordance with applicable laws
and regulations.

         Section 1.05. The services rendered by the Services Provider shall in
no way constitute the relinquishment of the management's responsibility of the
AmerUs Company receiving such service, which shall not be relieved of any
obligation or liability which it would otherwise be subject by law as a result
of those services being rendered.

ARTICLE II.  ADEQUATE STAFF AND FACILITIES

         Section 2.01. During the Service Period, the Services Provider shall

(90) days' written notice to the Services Provider. In addition, the Services
Provider, upon ninety (90) days' written notice may terminate any one or more of

terminated or substantially reduced at any time by mutual consent of the
parties.

ARTICLE VI.  MISCELLANEOUS

                      AMENDMENT NO. 2 TO FACILITY AGREEMENT


         This AMENDMENT NO. 2 TO FACILITY AGREEMENT (this "Amendment") is
entered into as of January 25, 2000 by and among AmerUs Life Holdings, Inc. (the
"Company"), Bank One, NA (f/k/a The First National Bank of Chicago),
individually and as agent ("Agent"), and the other finanial institutions
signatory hereto (the "Lenders").

                                    RECITALS

         A. The Company, the Agent and the Lenders are party to that certain
$27,500,000 Facility and Guaranty Agreement dated as of February 12, 1999 (as
previously amended, the "Facility Agreement"). Unless otherwise specified
herein, capitalized terms used in this Amendment shall have the meanings
ascribed to them by the Facility Agreement.

         B. The Company, the Agent and the undersigned Lenders wish to amend the
Facility Agreement on the terms and conditions set forth below in order to
accommodate, among other things, the merger (the "Merger") of the Company with
and into the reorganized stock company which results from the demutualization of
American Mutual Holding Company, the name of which is to be determined (the
"Reorganized Company").

         Now, therefore, in consideration of the mutual execution hereof and
other good and valuable consideration, the parties hereto agree as follows:

              1.   Amendment to Facility Agreement. Upon the Effective Date
(as defined below) or the Delayed Effective Date (as defined below), as
applicable, the Facility Agreement shall be amended as follows:

                   (a)  Article I is amended as follows:

                   (i)  by deleting the definitions of "Change of Control",
         "Company" and "Subsidiary" and replacing each in its entirety to read
         as follows:

                   "Change of Control" shall mean the occurrence of any of the
              following events: (i) the Company shall cease to own, directly, or
              indirectly through Wholly-Owned Subsidiaries, 100% of the issued

              vote for the election of directors, or any other class of stock of
              AmerUs Life of which the Company owns 50% or less shall become
              entitled to elect a majority of AmerUs Life's board of directors;
              or (ii) during any period of 25 consecutive calendar months,
              individuals who at the beginning of such period constituted the
              Board of Directors of the Company (together with any new directors
              whose election by such Board of Directors or whose nomination for
              election by the stockholders or members, as the case may be, of
              the Company was approved by a vote of a majority of the directors
              then


<PAGE>   2

              still in office who were either directors at the beginning of such
              period or whose election or nomination for election was previously
              so approved) cease for any reason to constitute a majority of such
              Board of Directors then in office.";

                   "Company" means the reorganized stock company which results
              from the demutualization of American Mutual Holding Company, the
              name of which is to be determined, and the successor by merger to
              AmerUs Life Holdings, Inc.";

                   "Subsidiary" of any Person shall mean and include (a) any
              corporation more than 50% of whose stock of any class or classes
              having by the terms thereof ordinary voting power to elect a
              majority of the directors of such corporation (irrespective of
              whether or not at the time stock of any class or classes of such
              corporation shall have or might have voting power by reason of the
              happening of any contingency) is at the time owned by such Person
              directly or indirectly through Subsidiaries and (b) any
              partnership, association, joint venture or other entity in which
              such Person directly or indirectly through Subsidiaries has more
              than a 50% equity or voting interest at the time. Unless otherwise
              expressly provided, all references herein to "Subsidiary" shall
              mean a Subsidiary of the Company; provided that, notwithstanding
              the foregoing provisions of this definition (x) any grantor trust
              or limited liability company established by the Company and/or its
              Subsidiaries in order to effectuate the lease/leaseback

              cogeneration facility in Linz, Austria as described in the summary
              of terms and structure delivered to the Administrative Agent and
              the Banks prior to the Fourth Amendment Effective Date (all as
              defined in the Existing Credit Agreement), and any trust or
              limited liability company formed by the Company and/or its
              Subsidiaries after the Fourth Amendment Effective Date to
              effectuate transactions with ESG or any other Person in which the
              Indebtedness of the Company and its Subsidiaries incurred in
              connection therewith is comprised solely of (i) obligations which
              are non-recourse to the Company or any of its Subsidiaries and
              (ii) other obligations which are or will be 100% defeased by U.S.
              Government obligations (each such transaction, including the
              lease/leaseback with ESG, a "Permitted Transaction") and (y) any
              Person which is at the relevant time of determination an
              Unrestricted Subsidiary (as such term is defined in the Existing
              Credit Agreement, as amended by the Sixth Amendment thereto dated
              as of May 18, 1999), shall not constitute a Subsidiary for
              purposes of this Agreement."

                   (ii)  by deleting the definition of "Group".

                   (iii) by adding the following definition for "Bank One" in
              its proper alphabetical order:

                   "Bank One" means Bank One, NA, a national banking
              association having its principal office in Chicago, Illinois, in
              its individual capacity, and its successors."

<PAGE>   3

                   (b)  Each reference therein to "First Chicago" is amended to
         be a reference to "Bank One" and each reference to "The First National

                   (c)  Section 5.01(a) is amended by adding the following at
         the end of such section:

                   "; provided, however, that AmerUs Life Holdings, Inc. may

              demutualization of American Mutual Holding Company,  the name of
              which is to be determined.

                   (d)  Section 6.01(g) is amended in its entirety to read as
         follows:

                   "(g) The Company shall default in the performance or
         observance of Section 5.01(e) or (h) herein or Section 7.10 or 7.11 of
         the Existing Credit Agreement (as amended by the Sixth Amendment
         thereto dated as of May 18, 1999)."

                   (e)  the first sentence of Section 10.01 is amended to add
the  following  at the conclusion thereof before the period:

         "and further provided that AmerUs Life Holdings, Inc. may assign such
         rights and obligations to the reorganized stock company which results
         from the demutualization of American Mutual Holding Company in
         connection with the Merger of AmerUs Life Holdings, Inc. into such

                              AGREEMENT AND RELEASE


         THIS AGREEMENT AND RELEASE, dated as of December 31, 1999, is entered
into by and between AmerUs Life Holdings, Inc., AmerUs Group Co., American
Mutual Holding Company, and all of their respective subsidiaries and affiliates
(collectively and individually "Employer") and Marcia S. Hanson ("Employee").

         In consideration of the payment by Employer of the Severance Amount and
Continued Benefits as hereinafter set forth and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Employee agrees as follows:

         1. ALL OTHER AGREEMENTS RESCINDED. Except as expressly otherwise herein
provided, this Agreement and Release supersedes and rescinds the Amended and
Restated Employment Agreement, dated April 15, 1999, between Employer and
Employee and all other agreements oral, written, express, implied or otherwise,
if any, between Employer and Employee, effective as of December 31, 1999 (the
"Termination Date").

         2. RELEASE AND WAIVER. Except for breaches of the rights provided in
Sections 6 and 7 of this Agreement and Release, Employee, on her behalf and on
behalf of others who might derive rights through her, fully and forever releases
and discharges Employer and each of its partners, principals, stockholders,
directors, officers, employees, agents, trustees, pension plan trustees and
administrators, contractors, consultants, and attorneys, whether past, present,
or future, and all predecessors, successors, and assigns thereof ("Released
Parties"), from any and all claims, demands, agreements, causes of action,
injunctions, and restraints or liabilities of whatever kind, arising out of or
in any way related to her employment with Employer or in her capacity as an
officer or a director of Employer, whether in law, equity, or otherwise, and
whether now known or unknown or which have ever existed or now exist, including,
but not limited to, claims, liabilities, or causes of action relating to or
arising out of Employee's hiring, employment, or separation from employment with

the Family Medical leave Act, 29 U.S.C. ss.2601 et. seq., Title VII of the Civil

<PAGE>   2

Privileged and Confidential


essential and material terms of this Agreement and Release and that without such
release, waiver, and covenant not to sue, no agreement would have been reached
by the parties.

         3. COVENANT NOT TO SUE. Employee covenants not to sue or to institute
or cause to be instituted any kind of claim or action in any federal, state or
local agency or court against any of the Released Parties arising out of or
attributable to Employee's employment, or separation from employment with
Employer, or any other action or cause of action released under Section 2
hereof.

         4. COMPLIANCE WITH APPLICABLE LAW. In order to comply with the Older
Workers Benefit Protection Act, Employee acknowledges that she is releasing any
claim she might have under the Age Discrimination in Employment Act. Employee
shall be given twenty one (21) days to consider entering into this Agreement and
Release. If Employee signs this Agreement and Release prior to the end of twenty
one (21) days, her signature shall constitute a waiver of that twenty-one day
consideration period. Employee shall further be given seven (7) days subsequent
to her execution of this Agreement and Release to revoke her execution. Proof of
execution shall be provided to Victor N. Daley, by delivering an executed
original Agreement and Release within forty-eight (48) hours of its execution.
Proof of revocation shall be provided by delivering a notice of revocation to
Victor N. Daley prior to the end of the seventh day after executing this
Agreement and Release. In the event Employee revokes execution pursuant to this
paragraph, Employer shall have no obligation under this Agreement and Release,
including no obligation to pay Employee the Severance Amount and Continued
Benefits as set forth herein.

         5. EMPLOYEE ADVISED TO SEEK LEGAL COUNSEL. Employee acknowledges that
Employer advised her to seek the advice of legal counsel before entering into
this Agreement and Release. Employee acknowledges that she has read this
Agreement and Release, that she fully understands and appreciates the meaning of
this Agreement and Release, that it fully reflects the entirety of the agreement
between the parties, that no representation, inducement, or warranty has been
made to her by or on behalf of Employer except as expressly set forth herein,
that she has consulted competent legal counsel of her selection, and that she
KNOWINGLY and VOLUNTARILY enters into this Agreement and Release and agrees to
comply with its terms and conditions.

         6. SEVERANCE AMOUNT. The Employee shall receive (i) an amount equal to
two (2) years base compensation of $240,000 per year, which sum shall be payable
in equal semimonthly installments during this two year period beginning on the
day after the Termination Date (the "Severance Period"), (ii) her targeted MIP
bonus at the fifty percent 50% level (i.e., $120,000) for each of the two years
of the Severance Period which shall be payable on March 1, 2000 and March 1,
2001, respectively, and (iii) an amount equal to her monthly flex credits which
shall be payable in equal semimonthly installments of $125 during the Severance
Period ((i), (ii) and (iii) collectively the "Severance Amount"). If Employee's
Termination Date is later than December 31st of 1999, the base compensation
portion (item (i) of the preceding sentence) of the Severance Amount shall be
reduced by the amount of Employee's base compensation earned



                                      -2-
<PAGE>   3

Privileged and Confidential

between December 31, 1999 and the Termination Date multiplied by .50. For
example, a May 1, 2000 Termination Date would result in a reduction of two (2)
months compensation providing Employee with a total two year base compensation
amount of $440,000.

         7. CONTINUED BENEFITS. In addition to the Severance Amount set forth in
Section 6 above, Employee shall receive the following benefits.

            a. Executive Stock Purchase. During the Severance Period, Employee
         shall remain eligible to continue her current participation as a
         participant in the Executive Stock Purchase Plan.

            b. Stock Options and 1999 MIP Payment. Employee's stock options
         shall as of the Termination Date be forfeited and no longer
         exercisable, and Employee shall not receive a 1999 MIP payment;
         however, in lieu of such options and MIP payment, Employee shall
         receive $280,000.

            c. MIP Deferral. Any amounts the Employee has deferred according to
         the AmerUs Group MIP Deferral Plan shall be paid on the Termination
         Date. Valuation of the MIP deferral shall be based on the December 31,
         1999 price of AMH Class A common stock.

            d. Long-term Incentive Plan. All deferred monies from the Long Term
         Incentive Plan plus earnings on those deferrals will be payable at
         termination. Additionally, the three year performance cycle payout
         ending December 31, 1999 will be paid as soon as the results are known.

            e. Vacation Pay. Employee shall receive in cash all accrued and
         unused vacation on the next regularly scheduled pay date following the
         Termination Date.

            f. Group Insurance Coverage. Employee's group medical and dental
         coverage shall continue until the Termination Date, and thereafter
         Employee shall be eligible to continue her medical and dental coverage
         under COBRA provisions, subject to applicable law. COBRA notices and
         enrollment forms shall be mailed to Employee's home from MedSoft
         Corporation, provided that Employee completes and returns the
         appropriate enrollment forms in accordance with such forms'
         instructions.

            g. Other Benefits. Employee's accidental death and dismemberment
         coverage shall end on the last day of the month of the Termination
         Date. All other fringe benefits provided by Employer, including
         short-term disability and long-term disability coverage, shall end on
         the Termination Date. Employee shall have the option of converting her
         long-term disability insurance utilizing the long-term disability
         conversion application previously provided to Employee. After
         completing and returning the application to Provident Life & Accident
         Insurance




                                      -3-
<PAGE>   4


Privileged and Confidential


         Company, Employee shall receive her individualized rate as provided for
         in the policy. There are no available conversion options for Employee's
         accidental death and dismemberment or short-term disability coverage.

            h. Life Insurance. Employee's basic group life, as well as any
         supplemental life, child life, and spouse life insurance elected shall
         all continue through the last day of the month of the Termination Date.
         Employee shall have the option to continue her supplemental life, child
         life, and spouse life insurance coverage through portability or
         conversion if elected within thirty one (31) days of cessation of
         coverage. Employee may "port" her supplemental life, child life, or
         spouse life insurance by completing a portability application that has
         been provided to Employee. Although Employee may not port her basic
         group life coverage, she shall have the option of converting her basic
         life insurance coverage, as well as any supplemental life, child life,
         and spouse life insurance coverage which Employee has elected, by
         completing a form that has been provided to Employee. Neither
         portability nor conversion requires underwriting and Employee may port
         and/or convert to an amount less than or equal to her basic and
         supplemental coverage combined, provided she does so within thirty one
         (31) days of the Termination Date.

            i. Retirement Plans. As of the Termination Date, Employee shall be
         vested in all employee and employer matching contributions to the
         All*AmerUs Savings & Retirement, SERP, and Excess Benefit Plans salary
         deferral. Employee's participation in the 401 (k) Plan shall end on the
         Termination Date, and Employee shall not take a distribution from the
         plan until thirty (30) days following the Termination Date.

         8. SUCCESSORS; BINDING AGREEMENT. This Agreement and Release shall be
binding on, inure to the benefit of, and be enforceable by the successors and
assigns of Employer. This Agreement and Release shall be binding on, inure to
the benefit of, and be enforceable by Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.

         9. NO ASSIGNMENT. The right of Employee or any other person to the
payment of amounts or other benefits under this Agreement and Release shall not
be assigned, alienated, hypothecated, placed in trust, disposed of, transferred,
pledged or encumbered (except by will or by the laws of descent and
distribution), and, to the extent permitted by law, no such amount or payment
shall in any way be subject to any legal process to subject the same to the
payments of any claim against Employee or any other person.

         10. NOTICE. For the purposes of this Agreement and Release, notices and
all other communications provided for in the Agreement and Release shall be in
writing and shall be deemed to have been duly given when hand delivered or
mailed by registered mail, return receipt requested, postage prepaid, addressed
to the respective addresses set forth below, provided that all notices to

courts in the State of Iowa. Any award so rendered shall be final and binding
upon the parties hereto. All costs and expenses of the arbitrator(s) shall be
paid as determined by such arbitrator(s), and all costs and expenses of experts,
witnesses, and other persons retained by the parties shall be borne by them
respectively.

         15. INJUNCTIVE RELIEF. In the event of a breach or threatened breach by
Employee of the provisions of this Agreement and Release, Employer shall be
entitled to an injunction to prevent irreparable injury to Employer. In this
regard, Employee understands and agrees that any breach by Employee of the
provisions of this Agreement and Release will result in serious and irreparable
injury to Employer and its business and that the remedy at law alone will be an
inadequate remedy for such breach.

         16. GENERAL CREDITOR. Nothing contained in this Agreement and Release
and no action taken pursuant to the provisions of this Agreement and Release
shall create or be construed to create a trust of any kind or a fiduciary
relationship between Employer and Employee or any other person, nor shall any
money or property of Employer be segregated for the benefit of Employee to
satisfy the obligations of Employer hereunder. To the extent that Employee
acquires a right to receive payments hereunder, such rights shall be no greater
than the right of any general unsecured creditor of Employer. Except as
expressly provided herein, each payment shall be made in cash from the general
assets of Employer.

         17. NONVESTED RIGHTS. The rights and benefits of Employee under this
Agreement and Release are nonvested rights and benefits of Employee.

         18. TAX WITHHOLDING. Employer will have the right to withhold from any
transfer or payment made to Employee or to any other person hereunder, whether
such payment is to be made in cash or other property, all applicable federal,
state, city or other taxes or foreign taxes as shall be required in the
determination of Employer, pursuant to any statute or governmental regulation or
ruling.

         19. DISCLOSURE OF INFORMATION. Employee hereby acknowledges that she
has had access to confidential information of Employer and of corporations
affiliated with Employer and that such information may constitute valuable,
special and unique property of Employer and such other corporations. Employee
shall not disclose any such confidential information to any person or entity for
any reason or purpose whatsoever, including, without limitation, the disclosure
of the terms and conditions of this Agreement and Release, except as may be
required by law. If Employee becomes legally compelled to disclose any
confidential information, Employee will provide Employer prompt notice thereof
so that Employer may seek a protective order or other appropriate



                                      -6-

Privileged and Confidential


remedy and Employee will cooperate with Employer in that effort. If such
protective order or other remedy is not obtained, Employee (a) will furnish only
that portion of the confidential information that Employee is advised by written
opinion of counsel is legally required; and (b) will exercise her best effort to
obtain reliable assurance that confidential treatment will be accorded such
confidential information.

         20. AGREEMENT NOT TO SOLICIT EMPLOYEES OR AGENTS. Employee agrees that,
for a period of three (3) years following the Termination Date, neither she nor
any affiliate shall, either alone or on behalf of any business engaged in
competition with Employer, solicit or induce, or in any manner attempt to
solicit or induce any person employed by, or an agent of, Employer to terminate
his or her contract or employment or agency, as the case may be, with Employer.

         21. NON-DISPARAGEMENT. Employee agrees that she shall not (a) take any
action to demean, disparage, or criticize Employer or any of Employer's
officers, employees, agents, directors, or stockholders; or (b) make any
negative or adverse remarks whatsoever to any third party, including without
limitation, actual or potential customers, investors of Employer, and past,
current or future employees, agents, and/or consultants of Employer, concerning
the business, operations, technologies, products, services, marketing
strategies, pricing policies, management, affairs and financial condition of
Employer and/or its successors, assigns, stockholders, officers, directors, and
employees; provided, however, that nothing contained in this Paragraph shall be
deemed to prohibit Employee from truthfully responding to inquires pursuant to
legal process or providing information as required by law.

         22. RETURN OF DOCUMENTS. Employee agrees that upon the Termination Date
Employee shall deliver to Employer all notes, letters, documents, and records
which may contain proprietary information which are then in her possession or
control and shall destroy any and all copies and summaries thereof not returned
to Employer.

         23. GOVERNING LAW. The provisions of this Agreement and Release shall
(except to the extent federal law applies) be construed in accordance with the
laws of the State of Iowa, without giving effect to any choice of law rules that
may require the application of the laws of another jurisdiction.

         24. ENTIRE AGREEMENT. This Agreement represents the entire
understanding and agreement between the parties hereto with respect to the
subject matter hereto, and upon the execution and delivery of this Agreement,
neither AMH nor Employee shall have any further rights, obligations or
liabilities under the Prior Agreement or any other written or oral agreement
relating to the subject matter hereof.

                         SUPPLEMENTAL BENEFIT AGREEMENT

         THIS SUPPLEMENTAL  BENEFIT  AGREEMENT (this  "Agreement") is entered
into and made effective as of the 7th day of February, 2000, by and between
           , an individual residing at                 ("Employee"), and AmerUs
Life Insurance Co., an Iowa corporation having its principal place of business
at 611 5th Avenue, Des Moines, Iowa  50309 ("Employer").

         WHEREAS, Employer currently employs Employee                         of
Employer; and

         WHEREAS, Employer and Employee wish to enter into an agreement
concerning a certain aspect of their employment relationship;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:

         Section 1. Definitions. Whenever used herein, capitalized words and
phrases, unless the context otherwise requires, shall have the meanings ascribed
in the text, or as set forth on Exhibit A, which is attached hereto and made a
part hereof.

         Section 2. Termination of Employment by Employee for Good Reason.

                  a. If the employment of Employee is terminated by Employee for
Good Reason, Employee shall be entitled to the Severance Payment and the
Continued Benefits.

                  b. Any offer of Comparable Employment following a Change of
Control shall remain open for at least fifteen (15) days after such offer is
extended to Employee. If Employee does not accept an offer of Comparable
Employment following a Change of Control within fifteen (15) days after it is
offered, all rights of Employee under this Agreement shall cease.

                   c. If Employee timely accepts an offer of Comparable
Employment following a Change of Control and if within two (2) years following
the date such offer of Comparable Employment is accepted either (i) the
employment of Employee is terminated by Employer without Cause (as such term is
described in Section 4 hereof) or (ii) a Material Event occurs and Employee
elects to terminate his or her employment with Employer (which will also be
considered a termination of employment by Employee for Good Reason for purposes
hereof), then Employee shall be entitled to the Severance Payment and the
Continued Benefits.

         Section 3. Termination of Employment by Employer Following Change of
Control. If the employment of Employee is terminated by Employer following a
Change of Control, and such termination is not for Cause as described in Section
4 hereof, Employee shall be entitled to the Severance Payment and the Continued
Benefits; provided, however, that if the Employee accepts an offer of Comparable
Employment, the provisions of Section 2(c) shall apply rather than this Section
3.



<PAGE>   2

         Section 4. Termination of Employment by Employer for Cause. Employer
may terminate the employment of Employee at any time for Cause. Employer shall
have "Cause" to terminate Employee's employment for Employee's personal
dishonesty, gross negligence, willful misconduct, breach of fiduciary duty
involving personal profit, intentional failure to perform stated duties, or
willful violation of any law, rule, regulation (other than traffic violations or
similar offenses) or final cease-and-desist order. Upon termination for Cause,
all rights of Employee under this Agreement shall cease as of the Termination
Date.

         Section 5. Notice of Termination. Any termination of the employment of
Employee shall be communicated by a Notice of Termination to the other party
hereto. If there is any dispute or controversy under this Agreement with respect
to Employee's entitlement to the Severance Payment or Continued Benefits, or the
amount of same, except in the event of a termination for Cause by Employer,
Employer shall continue to pay Employee the full compensation and benefits in
effect when the Notice of Termination was given (including without limitation
Base Compensation and payments under any bonus and incentive plans in which
Employee participates), until the earlier of the date when the dispute is
finally resolved or twelve (12) months from the date when the Notice of
Termination was given. Amounts paid under the preceding sentence shall be offset
against and shall reduce any other amounts due under this Agreement, including
any Severance Payment or Continued Benefits and any arbitration award under
Section 11 hereof.

         Section 6. Severance Payment. In the event the employment of Employee
is terminated by Employee for Good Reason as described in Section 2 hereof or by
Employer following a Change of Control as described in Section 3 hereof,
Employer shall pay to Employee the following Severance Payment, which shall be
paid in a lump sum within thirty-five (35) days following the Termination Date:

                  a.       Any amount of Employee's Base Compensation earned but
unpaid through the  Termination Date; and

                  b. In lieu of any further salary or other payments of any kind
to Employee for periods after the Termination Date, an amount equal to:

                           i.      the sum of:

                                   (1)      Employee's Base Compensation, plus

                                   (2)      the amount of Employee's annual
                                            bonus that would have been paid
                                            immediately preceding the
                                            Termination Date assuming the Plan
                                            Target Level (as defined by the
                                            Plan) had been achieved;

                           ii.     multiplied by the number two(2); and

                  c. An amount equal to the contributions from the Employer the
Employee would have otherwise been entitled to under the Plans if Employee had
remained an employee of Employer


                                       3
<PAGE>   3

until and including December 31 of the calendar year in which Employee's
employment terminates and Employee had earned the amounts set forth in Section
6.b.i above through said December 31st; provided, however, if Section 280G(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), is applicable, the
amount of Severance Payment described herein shall be limited to the extent
necessary so that, within the meaning of Section 280G(b)(2)(A)(ii) of the Code,
the aggregate present value of the payments in the nature of compensation to (or
for the benefit of) the Employee which are contingent on a Change of Control
(with a Change of Control for this purpose being defined in terms of a "change"
described in either Section 280G(b)(2)(A)(i)(I) or (II) of the Code) are limited
to an amount equal to 2.999 multiplied by the "base amount," as such term is
defined in Section 280G(b)(3) of the Code.

         Section 7. Continued Benefits. In the event the employment of Employee
is terminated by Employee for Good Reason as described in Section 2 hereof or by
Employer following a Change of Control as described in Section 3 hereof,
Employer shall continue to provide to Employee the Continued Benefits described
in this Section 7. Employer shall maintain in full force and effect, for the
benefit of Employee for two (2) years after the Termination Date, all employee
welfare benefit plans and programs or arrangements in which Employee was
entitled to participate immediately prior to the Termination Date (the
"Continued Benefits"); provided, however, that Employee's continued
participation is possible under the general terms and provisions of such plans,
programs and arrangements. In the event that Employee's continued participation
in any such plan, program or arrangement is not possible, Employer shall arrange
to provide Employee with substantially equivalent benefits. At the end of the
period of coverage, Employee shall have the option to have assigned to Employee
at no cost and with no apportionment of prepaid premiums any assignable
insurance policy owned by Employer and relating specifically to Employee.
Notwithstanding the foregoing, Employee's period of continued coverage under any
such plan, program or arrangement (or any Employer-arranged provision of such
benefits) shall terminate as of the date Employee becomes eligible to
participate in a similar plan, program or arrangement of another employer.
Employee shall be deemed to be "eligible to participate" for this purpose even
if Employee is required to pay an employee premium and even if the new plan,
program or arrangement imposes preexisting condition limitations or
restrictions. In addition, Employee shall be fully vested in all of his or her
account in the AllHAAmerUs Savings & Retirement Plan and the AllHAAmerUs
Supplemental Executive Retirement Plan.

         Section 8. No Mitigation. Employee shall not be required to mitigate
the amount of any Severance Payment or Continued Benefits by seeking other
employment or otherwise, nor shall the amount of any Severance Payment or
Continued Benefits (other than the earlier termination of certain employee
benefits as described in Section 7 hereof) be reduced by any compensation earned
by Employee as a result of employment by another employer after termination of
this Agreement or otherwise. Employer's obligation to pay Employee the
compensation and make the arrangements provided herein shall be absolute and
unconditional and, following any Change of Control, shall not be affected by any
circumstances, including without limitation any set-off (except as provided in
Sections 5 and 9.b. hereof), counterclaim, recoupment, defense or other rights
which Employer may have. Except as otherwise provided herein, all amounts
payable by Employer shall be paid without notice or demand.

         Section 9.      Indemnification.

                  a.     Employer shall pay, and indemnify Employee against, all
costs and expenses, including without limitation the fees and expenses of
attorneys, arbitrators, experts and witnesses, incurred by or on behalf of
Employee in connection with any arbitration or legal claim or proceeding arising
from this Agreement or the interpretation thereof, to the extent that Employee
is successful, on the merits or otherwise, in any such claim or proceeding. If
Employee is not wholly successful in such claim or proceeding but is successful,
on the merits or otherwise, as to one or more but less than all claims, issues
or matters in such claim or proceeding, then Employer shall indemnify Employee
against all such costs and expenses incurred by Employee or on Employee's behalf
in connection with each successfully resolved claim, issue or matter.

                  b.     Employer shall advance all such costs and expenses
incurred by or on behalf of Employee in connection with any such claim or
proceeding referred to in Section 9.a. hereof within twenty (20) days after
receipt by Employer of a statement or statements from Employee requesting such
advance or advances, whether prior to or after final disposition of such claim
or proceeding. Such statement or statements shall reasonably evidence the costs
and expenses incurred by Employee and shall be preceded or accompanied by an
undertaking by or on behalf of Employee to repay any costs and expenses advanced
if it shall ultimately be determined that Employee is not entitled to be
indemnified against such costs and expenses and, furthermore, if Employee fails
to repay any costs and expenses that are advanced, then such amounts shall be
offset against and shall reduce any other amounts due to Employee under this
Agreement.

         Section 10.     Notices. All notices and other communications provided
for or permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telecopier or commercial courier guaranteeing next day
delivery to the respective addresses provided for Employer and Employee in the
introductory paragraph of this Agreement. Notices to Employer shall be addressed
to the attention of the Chief Executive Officer and the Corporate Secretary of
Employer. All such notices and communications shall be deemed to have been duly
given; at the time delivered by hand, if personally delivered; five (5) business
days after being deposited in the mail, postage prepaid, if mailed; when receipt
is acknowledged, if telecopied; and the next business day after timely delivery
to the courier, if sent by commercial courier guaranteeing next day delivery.

         Section 11.     Arbitration. Employer and Employee agree that any
disputes arising out of or relating to this Agreement shall be arbitrated in
accordance with the rules of the American Arbitration Association and the
Federal Arbitration Act. Such arbitration shall be held in Des Moines, Iowa. No
party shall initiate arbitration unless, at least thirty (30) days prior
thereto, such party has given the other party written notice of the intent to
initiate arbitration and a detailed description of the basis of the dispute. A
single arbitrator (or, in any matter in which the amount in controversy exceeds
$500,000, a panel of three (3) arbitrators) shall interpret this Agreement in
accordance with Iowa laws and shall conduct proceedings in accordance with the
Federal Rules of Civil Procedure. Punitive damages, if any, awarded by the
arbitrator(s) shall not exceed two (2) times compensatory damages awarded. Any
award of the arbitrator(s) shall be deemed final, and judgment upon such award
may be entered and enforced in any Iowa District Court and transferred to any
other jurisdiction.

         Section 12.     Tax Withholding. Employer shall have the right to
withhold from any transfer or payment made to Employee or to any other Person
hereunder, whether such payment is to be made in cash or other property, all
applicable federal, state, city or other taxes or foreign taxes as shall be
required in the determination of Employer pursuant to any statute or
governmental regulation or ruling.

         Section 13.     Interest. Employer shall pay Employee interest at a
rate of ten percent (10%) per annum on any benefits payable to Employee
hereunder not paid by the date provided for herein from such date until the date
of payment.

         Section 14.     General Creditor. Nothing contained in this Agreement
and no action taken pursuant to the provisions of this Agreement shall create or
be construed to create a trust of any kind or a fiduciary relationship between
Employer and Employee or any other Person, nor shall any money or property of
Employer be segregated for the benefit of Employee to satisfy the obligations of
Employer hereunder. To the extent that Employee acquires a right to receive
payments hereunder, such rights shall be no greater than the right of any
general unsecured creditor of Employer. Except as expressly provided herein,
each payment shall be made in cash from the general assets of Employer.

         Section 15.     No Waiver. The failure of either party to require the
performance of any term or condition of this Agreement, or the waiver by either
party of any breach of this Agreement, shall not prevent a subsequent
enforcement of any term or condition nor be deemed to be a waiver of any
subsequent breach by either party.

         Section 16.     Binding Effect. This Agreement shall be binding on and
inure to the benefit of the successors and assigns of Employer. This Agreement
shall inure to the benefit of and be enforceable by Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.

         Section 17.     No Assignment. The right of Employee or any other
Person to the payment of amounts or other benefits under this Agreement shall
not be assigned, alienated, hypothecated, placed in trust, disposed of,
transferred, pledged or encumbered (except as provided in Section 16 herein)
and, to the extent permitted by law, no such amount or payment shall in any way
be subject to any legal process to subject the same to the payments of any claim
against Employee or any other Person.

         Section  18.    Paragraphs and Other Headings.  The paragraph headings
contained in this Agreement are for reference purposes only and shall not affect
the interpretation of this Agreement.

         Section  19.    Governing  Law.  This Agreement and all transactions
contemplated by this Agreement shall be governed by, and construed and enforced
in accordance with, the laws of the State of Iowa, without regard to principles
of conflicts of laws.

         Section 20.     Severability. If any one or more of the provisions
contained in this Agreement shall for any reason be held invalid, illegal or
unenforceable, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Agreement, which shall be construed as

                                       6

<PAGE>   6

if such invalid, illegal or unenforceable provision had never been contained
herein. It is the intention of the parties that if any provision of this
Agreement is capable of two constructions, one of which would render the
provision void and the other of which would render the provision valid, then the
provision shall have the meaning that renders it valid.

         Section 21.     At-Will Employment. Nothing in this Agreement shall
alter the "at-will" nature of Employee's employment with Employer, it being
understood that the "at-will" nature of Employee's employment with Employer
shall in no way alter the benefits to which Employee is otherwise entitled under
this Agreement.

         Section 22.     Survivability.  The obligations of Employer and
Employee under this Agreement shall survive the termination of this Agreement.

         Section 23.     Employer After A Change of Control. Following a Change
of Control and the acceptance by Employee of an offer of Comparable Employment,
the term "Employer" shall be deemed to mean the actual employer of Employee
(which may be Employer, an affiliate thereof or some other Person involved in
the Change of Control).

         Section 24.     Entire Agreement. This Agreement sets forth the entire
understanding of the parties and supersedes all other representations,
agreements and understandings, oral or otherwise, between or among the parties
with respect to the matters contained herein.

         IN WITNESS WHEREOF, the parties have set their respective signatures as
of the day and year first above written.

                                   DEFINITIONS


         "Affiliate" shall mean with respect to any Person, any Person which,
directly or indirectly, through one or more intermediaries, controls, is
controlled by or is under common control with such entity; provided, however,
that any Person which owns directly or indirectly ten percent (10%) or more of
the securities having ordinary voting power for the election of directors or any
other governing body of a corporation or ten percent (10%) or more of the
partnership or other ownership interests of any other Person (other than as a
limited partner of such Person) will be deemed to control such Person.

         "AMHC" shall mean American Mutual Holding Company.

         "Base Compensation" shall mean the greater of (i) the semi-monthly
salary paid to Employee by Employer which was in effect immediately prior to the
Termination Date or (ii) the semi-monthly salary paid to Employee by Employer
which was in effect prior to any reduction thereof made without the written
consent of Employee, in either case multiplied by twenty-four (24).

         "Change of Control" shall mean any Transaction or series of
Transactions involving Employer or any Affiliate of Employer which results in
either (i) AMHC not directly or indirectly owning or controlling shares of stock
of the Employer sufficient to cast a majority of the votes necessary to elect
members of the Board of Directors of the Employer ("Voting Control"); (ii) the
individuals who, prior to such Transaction, constituted the board of directors
of AMHC ceasing to constitute at least a majority thereof, unless the election,
or the nomination for election of each director of AMHC for a period of two (2)
years following the consummation of such Transaction was approved by a vote of
at least two-thirds of the directors of AMHC then still in office who were
directors of AMHC prior to such Transaction; (iii) the individuals who, prior to
such Transaction, constituted the board of directors of Employer ceasing to
constitute at least a majority thereof, unless the election, or the nomination
for election of each director of the Employer for a period of two (2) years
following the consummation of such Transaction was approved by a vote of at
least two-thirds of the directors of Employer then still in office who were
directors of Employer prior to such Transaction; or (iv) the acquisition by any
Person other than AMHC or its subsidiaries of the beneficial ownership, as
defined in Rule 13d-3 of the Securities Exchange Act of 1934, of more than
twenty-five percent (25%) of the shares of stock of the Employer which are
entitled to elect the board of directors of the Employer at any time that AMHC
does not have beneficial ownership of the Voting Control of the Employer;
provided, however, that in the case of (i), (ii) and (iii), a Transaction which
is a Demutualization shall not constitute a Change of Control if the directors
elected or nominated for election to either AMHC's or Employer's respective
board of directors by AMHC's or Employer's respective stockholders following the
Demutualization were the directors of AMHC or Employer, respectively, prior to
such Demutualization, or if the election, or the nomination for election, by
AMHC's or Employer's respective stockholders, of each director of AMHC or
Employer, respectively, for a period of two (2) years following the consummation
of such Demutualization was approved by a vote

                                       1

<PAGE>   8

of at least two-thirds of the directors of AMHC or Employer then still in office
who were the respective directors of AMHC or the Employer prior to such
Demutualization.

         "Comparable Employment" shall mean employment with Employer, an
Affiliate thereof or a third party involved in any Change of Control on terms
and conditions (including without limitation geographic location) which in the
aggregate are at least substantially comparable to the terms and conditions of
employment prevailing with respect to Employee immediately preceding a Change of
Control.
