     This Post-Effective Amendment No. 1 by the Company relates to the
Registration Statement on Form S-3 (File No. 333-72643) of AmerUs Life Holdings,
Inc., relating to its shares of Class A Common Stock previously registered for

the Company hereby adopts Registration Statement No. 333-72643 as its own for

merger described below.

     Pursuant to the Agreement and Plan of Merger, dated December 17, 1999,

Company as the surviving corporation. The merger became effective on September

AmerUs Life Holdings issued prior to the merger was automatically converted into

Company.

     The merger and related transactions are described in the Company's
Registration Statement on Form S-4 (File No. 333-36992).

                                    THE PLAN

ADMINISTRATION OF THE PLAN

     The plan will be administered by Douglas K. Owens, Vice President -
Compensation of AmerUs or any successor designated by our chief human resources
officer or our board of directors.

PLAN ELIGIBILITY

     Our agents and other non-employees will be eligible to receive options or
stock appreciation rights under the plan pursuant to criteria established by the
administrator. Each person who receives an award under the plan is referred to
as a participant. We have no obligation to select any or all agents or
non-employees for participation in the plan. For purposes of the plan, an agent
is a person who

          -    is an agent, managing general agent, personal producing agent or
               other person,

          -    is an independent contractor, and

          -    receives commissions, overrides or other amounts in connection
               with the sale of life insurance or annuities issued by one of our
               subsidiaries.


A non-employee is a person who is neither an agent nor an employee, but
significantly contributes to our success.

THE GRANT OF AWARDS

     Each year we will announce whether awards will be granted, the criteria for
granting awards, the vesting requirements for awards granted and all other
provisions designated by the administrator with respect to those awards to be
granted during that year. Awards will consist of stock options and/or stock
appreciation rights.

                                     OPTIONS

OPTION PRICES

     When we grant an option, the administrator will determine its exercise
price. The exercise price will not be less than the closing price of the common
stock as of the date of grant reported on the New York Stock Exchange, or the
principal market on which the common stock is traded, if not listed on that
exchange.

EXERCISING AN OPTION

     Subject to certain restrictions, participants may exercise options that are
vested. Each option will be effective for no more than ten (10) years. If an
option is not fully exercised by its expiration date it will terminate to the
extent not previously exercised. The administrator will determine the schedule
for the vesting of options. The administrator may also condition the exercise of
options on performance goals or other criteria.

     A participant may exercise an option by delivering written notice to us and
paying the exercise price. Participants may exercise options in full or in part,
but not for less than 100 shares of common stock. Options exercisable for less
than 100 shares may only be exercised for the full number of shares covered. A
participant will become a shareholder of those shares for which an option is
exercised at the time the administrator determines that the exercise is valid,
the option price has been received and a certificate for the shares has been
issued. We will issue shares of common stock as soon as practicable after
exercise, but no sooner than ten (10) days after receiving notice of exercise.

PAYMENT OF THE OPTION PRICE

     A participant may pay the exercise price of an option in cash or by check.
If the administrator agrees, and the participant satisfies any conditions in the
option agreement, the participant can pay the exercise price by delivering
previously held shares of the common stock or by a combination of cash and
shares. If a participant uses shares for this payment, the value of each share
delivered shall be the closing price reported on the New York Stock Exchange, or
the principal market on which the common stock is traded, if not listed on that
exchange, on the last trading date prior to the date of exercise.


                                       9
   10

                            STOCK APPRECIATION RIGHTS

     We will designate awards of stock appreciation rights in stock units. The
administrator will determine the number of stock units granted for any award of
stock appreciation rights. Each stock unit granted to a participant entitles
that participant to receive an amount in cash or shares of common stock. The
value of a stock unit will be equal to the difference between the fair market
value of one share of common stock on the date of exercise of the stock unit and
the fair market value of one share of common stock on the date that we grant the
stock unit. The administrator will determine if the participant will receive
cash or shares of common stock upon exercise of stock units.

     A participant may exercise his or her stock appreciation rights after an
initial restricted period. The administrator will determine the length of the
restricted period. The administrator will also determine the time frame, after
the initial restricted period, during which a participant may exercise his or
her stock appreciation rights. That time frame will be no more than ten (10)
years from the date of grant. The time frame will be stated in the participant's
stock appreciation rights agreement.

                               GENERAL PROVISIONS

AVAILABLE SHARES

     Subject to adjustments for stock splits, stock dividends and other changes
in the number and character of shares of common stock available for awards, we
will grant awards for up to 100,000 shares of common stock under the plan. The
shares that we will deliver upon the exercise of options or in connection with
stock appreciation rights may be authorized but unissued shares of common stock,
issued shares of common stock which we have been reacquired or a combination.

     In the event of a stock split, stock dividend or similar change in the
number and character of shares of common stock available for awards, we will
adjust

          -    the number of shares of common stock available for awards under
               the plan,

          -    the exercise price per share of common stock under each
               outstanding option, and

          -    the number and value of stock units granted under the plan.


                                       10
   11

     The purpose and effect of this type of adjustment is to give you the same
economic rights in our common stock that you had prior to a stock split, stock
dividend or similar change.

THE EXERCISE OF AWARDS BY NON-PARTICIPANTS

     You may not transfer awards other than by will or by the laws of descent
and distribution upon death. In the case of your death, your estate or heirs may
exercise the award within thirty (30) days of death, to the same extent that you
could have exercised the award at the time of your death.

THE TERMINATION OF AWARDS

     All awards terminate at the end of the term established by the
administrator. The term may be no longer than ten (10) years from the date of
grant.

     If we terminate our relationship with you for a material breach, any
unexercised awards you hold will automatically terminate on the date that we
give you notice of the material breach and/or the termination of your contract
with us. A "material breach" means that you have breached a contract or an
agreement with us and your breach constitutes conduct that causes us a monetary
or other injury, including any act of dishonesty or improper sales. If you are a
general agent, a material breach includes the conduct of your insurance agency.

     If your relationship with us is terminated for any other reason, including
death or disability, you, or your heirs in the case of death, may exercise your
award(s), solely to the extent that you were entitled to do so at the date of
termination, for a period of thirty (30) days after the date of termination. Any
unexercised awards will automatically terminate to the extent not exercised
within this thirty (30) day period. The administrator will determine whether
these provisions apply in the event that you maintain or enter into a different
contract or relationship with us. This includes a change by an agent from a
contract that includes a minimum production requirement to one that does not.

     If your relationship with us terminates, you will not be eligible to
receive awards after the date of termination of the relationship. Any
outstanding but unexercised awards will terminate as described in the preceding
paragraph.

THE STATUS OF AN AWARD HOLDER

     Receiving an award does not give you any right to continue your
relationship with us, and it does not interfere with our right to terminate our
relationship with you at any time.

     You will not have rights as a shareholder for any shares of common stock
subject to an award until the date we issue those shares.


                                       11
   12

CHANGE OF CONTROL OF AMERUS

     If we are a party to a merger or consolidation or if there is a tender
offer for shares of our common stock, the administrator can make adjustments to
the awards as necessary or appropriate, including:

          -    substituting new awards,

          -    terminating or adjusting outstanding awards, and

          -    accelerating or removing restrictions on outstanding awards.


PARTICIPANT'S AGREEMENTS

     The terms and conditions of your award(s) will be contained in an agreement
or agreements between you and us. The terms of your agreement(s) will be
consistent with the terms of the plan, but may include additional provisions and
restrictions that are not inconsistent with the plan.

CONDITIONS TO ISSUE OR DELIVER COMMON STOCK

     Our obligation to issue or deliver shares of common stock upon the exercise
of an award is subject to applicable laws and the approval of applicable
governmental and regulatory authorities, including the consent or approval of
the Iowa Commissioner of Insurance, if necessary or appropriate. As previously
noted, we have the sole discretion to deliver cash or shares of common stock
upon the exercise of stock appreciation rights.

RESALE OF COMMON STOCK

     You may publicly sell shares of common stock acquired pursuant to the plan.
However, if you may be considered our "affiliate" as defined in the SEC rules
under the Securities Act of 1933 any shares that you own may not be re-offered
or resold except:

          -    under a separate prospectus covering those shares,

          -    in connection with Rule 144 under the rules of the Securities
               Act, or

          -    under another Securities Act exemption from registration.

                               TAX CONSIDERATIONS

OPTIONS

     Options granted under the plan are non-qualified options under the Internal
Revenue Code. The grant of options will not result in the recognition of taxable
income for federal income tax purposes. When a participant exercises an option,
the participant recognizes, as ordinary income, the excess of the fair market
value of the common stock on the date of exercise over the exercise price. We
will be allowed a deduction for federal income tax purposes to the same extent
and at the same time as the participant recognizes income.

     The tax basis of a share acquired by exercise of an option with a cash
payment will be its fair market value used to determine the amount of taxable
income arising from the exercise of the option. The holding period for purposes
of determining whether a subsequent sale of the share results in the recognition
of short-term or long-term capital gain or loss will begin on the day of
transfer of the share to the participant.

     If a participant delivers shares of common stock that he or she already
owns as payment of the exercise price of shares acquired on the exercise of an
option, the delivery will not result in the recognition of a capital gain or
loss on the previously owned stock. The number of option shares received in
excess of the previously owned shares given up, in effect, are "purchased" with
the untaxed appreciation on the previously owned stock. A participant's tax
basis and holding period for the number of shares received equal to the number
of shares delivered will be the same as that for the shares delivered. A
participant's tax basis for shares received in excess of the number of shares
delivered will equal the fair market value of the shares used to determine the
amount of taxable income arising from the exercise of the option. A
participant's holding period for those excess shares will begin on the date the
shares are transferred to the participant.

STOCK APPRECIATION RIGHTS

     Generally, a participant will not realize taxable income upon the grant of
a stock appreciation right. A person granted a stock appreciation right will
realize ordinary income on the date the stock appreciation right is exercised in
an amount equal to the sum of any cash received plus the fair market value
determined as of the date of exercise of any shares received. We will be allowed
a deduction for federal income tax purposes to the same extent and at the same
time as the participant recognizes income.

     The tax basis of a share acquired by exercise of a stock appreciation right
will be its fair market value used to determine the amount of taxable income
arising from the exercise of the stock appreciation right. The holding period
for purposes of determining whether a subsequent sale of the share results in
the recognition of short-term or long-term capital gain or loss will begin on
the date of transfer of the share to the person exercising the stock
appreciation right.

GENERAL

     We will report the amount of taxable income arising from the exercise of an
option or a stock appreciation right on IRS Form 1099. You should consult your
tax advisor to determine the income tax consequences of holding and exercising
any awards granted under the plan and of selling any stock acquired pursuant to
that exercise, as well as to determine the effect of any state or local taxes.

     The plan is not qualified under Section 401(a) of the Internal Revenue Code
and is not subject to any provisions of the Employee Retirement Income Security
Act of 1974, as amended.

                              OTHER CONSIDERATIONS

     The plan will continue in effect until all awards that we have granted
expire. We will not grant any awards under the plan after February 12, 2009. The
administrator or our board of directors may amend, suspend or terminate the
plan. However, no action shall adversely affect or impair in any material
respect any award granted under the plan without the consent of the participant
holding the award.

                                 USE OF PROCEEDS

     We will use any proceeds from the exercise of awards for general corporate
purposes.

                                  LEGAL MATTERS

     The legality of the common stock offered under this prospectus will be
passed upon by Joseph K. Haggerty, Esq., Senior Vice President and General
Counsel of AmerUs. Mr. Haggerty beneficially owns 31,087 shares of our common
stock and has options to purchase 30,000 shares of our common stock.

              ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

          Previously disclosed in the original Registration Statement.

               ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 490.832 of the Iowa Business Corporation Act (the "IBCA")
provides that a corporation's articles of incorporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its shareholders for monetary damages for breach of fiduciary duty as a
director, provided that the provision does not eliminate or limit the liability
of a director for a breach of the director's duty of loyalty to the corporation
or its shareholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, for a transaction from
which the director derives an improper personal benefit, or under Section
490.833 of the IBCA. Further, Section 490.851 of the IBCA provides that a
corporation may indemnify its directors against liabilities and reasonable
expenses incurred by reason of such person serving in the capacity of director,
if such person has acted in good faith and in a manner reasonably believed by
the individual to be in or not opposed to the best interests of the corporation,
and in any criminal proceeding if such person had no reasonable cause to believe
the individual's conduct was unlawful. The indemnity provisions under Section
490.851 shall not apply (i) in the case of actions brought by or in the right of
the corporation in which the director was adjudged liable to the corporation, or
(ii) in connection with any other proceeding charging improper personal benefit
to the director, whether or not involving action in the director's official
capacity, in which the director was adjudged liable on the basis that impersonal
benefit was improperly received by the director. In addition, Section 490.852 of
the IBCA provides mandatory indemnification of reasonable expenses incurred by a
director who successfully defends any action in which the director was a party
because the director is or was a director of the corporation. Finally, Section
490.856 of the IBCA provides that, unless otherwise provided in a corporation's
articles of incorporation: (i) an officer of the corporation who is not a
director is entitled to mandatory indemnification under Section 490.852 of the
IBCA and is entitled to apply for court-ordered indemnification under Section
490.854 of the IBCA in each case to the same extent as a director, (ii) the
corporation may indemnify and advance expenses under Section 490.852 to an
officer, employee, or agent of the corporation who is not a director to the same
extent as to a director, and (iii) a corporation may also indemnify and advance
expenses to an officer, employee, or agent who is not a director to the extent,
consistent with law, that may be provided by its articles of incorporation,
bylaws, general or specific action of its board of directors, or contract.



                                       15
   16

          The Company's Articles of Incorporation provide that no director of
the Company will be liable to the Company or its shareholders for monetary
damages for any breach of fiduciary duty as a director, except to the extent
otherwise required by the IBCA. This provision will not prevent shareholders
from obtaining injunctive or other equitable relief against directors nor will
it shield directors from liability under Federal or state securities laws. In
addition, the Articles of Incorporation provide that the Company will to the
maximum extent permitted by law, indemnify a person who incurs any loss by
reason of the fact that he or she is or was or has agreed to be a director or
officer of the Company or while a director or officer of the Company is or was
serving at the request of the Company as a director, officer, partner, trustee,
employee or agent of any corporation, partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, subject to
such person having met the standards of conduct required for such
indemnification under Iowa law.

          As permitted by and in accordance with Section 490.857 of the IBCA,
the Company maintains a directors' and officers' liability insurance policy to
insure against losses arising from claims made against its directors and
officers, subject to the limitations and conditions as set forth in the
policies. In addition, the Company has entered into indemnification agreements
with its directors and certain of its executive officers providing for the
indemnification of such persons as permitted by the Company's Articles of
Incorporation and Iowa law.

                             ITEM 17. UNDERTAKINGS.

(a)  The undersigned registrant hereby undertakes:

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

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

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

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


                                       17
   18

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

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

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

(h) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

Company certifies that it has reasonable grounds to believe that it meets all of
the requirements for filing on Form S-3 and has duly caused this Post-Effective
Amendment No. 1 to the Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized in the City of Des Moines, State of Iowa,
