   [FORM OF REVERSE SIDE OF GLOBAL SECURITY]  

AMERICAN EQUITY INVESTMENT LIFE HOLDING COMPANY  

Series B 5.25% Contingent Convertible Senior Note Due 2024  

        (1)   New
Series of Securities. 

        This
Security shall constitute a new, separate series of Securities under the Indenture and Holders hereof shall constitute a separate class of Holders. 

        (2)   Interest.

        This
Security will bear interest from December 6, 2004 or from the most recent date to which interest has been paid or duly provided for, semi-annually in arrears on
June 6 and December 6 of each year (each, an "Interest Payment Date"), subject to Section 11.08 of the Indenture, commencing
June 6, 2005. The Company will pay interest on any overdue principal amount at the interest rate borne by the Securities at the time such interest on the overdue principal amount accrues,
compounded semi-annually, and it shall pay interest on overdue installments of interest and Contingent Interest and Liquidated Damages, if any (without regard to any applicable grace
period), at the same interest rate, compounded semi-annually. Interest (including Contingent Interest and Liquidated Damages, if any) on the Securities will be computed on the basis of a
360-day year comprised of twelve 30-day months. 

        The
Company shall pay additional interest ("Contingent Interest") to the Holders during any six-month period (a  "Contingent Interest Period") from and
including an Interest Payment Date to but excluding the next Interest Payment Date, commencing with the
six-month period ending June 6, 2012, if the average Trading Price per Security for the five Trading Days ending on the third Trading Day immediately preceding the first day of the
applicable Contingent Interest Period (the "Contingent Interest Average Trading Price") equals 120% or more of the principal amount of such Security.
The amount of Contingent Interest payable per $1,000 principal amount of Securities in respect of any Contingent Interest Period shall equal 0.50% per annum on the Contingent Interest Average Trading
Price. The Company will pay Contingent Interest, if any, in the same manner and at the same time as it will pay interest as described above. 

        Upon
determination that Holders will be entitled to receive Contingent Interest for a Contingent Interest Period, on or prior to the first day of such Contingent Interest Period, the
Company shall issue a press release and notify the Trustee promptly in writing. 

        (3)   Method
of Payment. 

        The
Company will pay interest (including Contingent Interest and Liquidated Damages, if any) on this Security to the Person who is the registered Holder of this Security at the close of
business on May 20 or November 20 (each a "Record Date"), as the case may be, immediately preceding the related Interest Payment Date.
Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Redemption Price, Repurchase Price, Change in Control Repurchase Price and the
principal amount at Stated Maturity, as the case may be, to the Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the Security. The Company will pay cash
amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may pay interest (including Contingent Interest and
Liquidated Damages, if any), the Redemption Price, Repurchase Price, Change in Control Repurchase Price and the principal amount at Stated Maturity, as the case may be, to a Holder holding Securities
in definitive form by check or wire payable in such money; provided that a Holder holding Securities in definitive form with an aggregate principal
amount in excess of $1,000,000 may request payment by wire transfer in immediately available funds to an account in North America at the election of such Holder. The Company may mail an interest check
to the Holder's registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer
of immediately available funds to the account of the Depositary or its nominee. 

        (4)   Paying
Agent, Conversion Agent and Registrar. 

        Initially,
U.S. Bank National Association (the "Trustee") will act as Paying Agent, Conversion Agent and Registrar. The Company may
appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company will
maintain at least one Paying Agent having an office or agency in the State of New York, City of New York, Borough of Manhattan, which shall initially be an 

A-5

 

office
or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 

        (5)   Indenture.

        The
Company issued the Securities under an Indenture dated as of December 6, 2004 (the "Original Indenture") between the Company
and the Trustee, as supplemented by the First Supplemental Indenture dated as December 30, 2004 (the "Supplemental Indenture", and together with
the Original Indenture, the "Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the "TIA"). Capitalized terms used
herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement
of those terms. 

        The
Securities are senior unsecured obligations of the Company and may be issued in unlimited principal amount under the Indenture. The Indenture does not limit other indebtedness of the
Company, secured or unsecured. 

        (6)   Redemption
at the Option of the Company. 

        No
sinking fund is provided for the Securities. Beginning on December 15, 2011 and during the periods thereafter to maturity, the Securities of this series are redeemable as a
whole at any time, or in part from time to time, in any integral multiple of $1,000, at the option of the Company for cash at a Redemption Price equal to 100% of the principal amount, together with
accrued but unpaid interest (including Contingent Interest and Liquidated Damages, if any) thereon, up to but not including the Redemption Date;  provided that, if the Redemption Date is between the
close of business on a Record Date and the opening of business on the related Interest Payment
Date, interest will be payable to the Holders in whose names the Securities are registered at the close of business on the relevant Record Date. 

        Notice
of redemption pursuant to paragraph 5 of this Security will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of
Securities to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Securities of this series (or portions thereof) to be redeemed on the Redemption
Date is deposited with the Paying Agent prior to 11:00 a.m., New York City time, on the Redemption Date, immediately after such Redemption Date, interest (including Contingent Interest and
Liquidated Damages, if any) shall cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of principal amount may be redeemed in part but only in
integral multiples of $1,000 of principal amount. 

        (7)   Repurchase
By the Company at the Option of the Holder on Specified Dates; Repurchase at the Option of the Holder Upon a Change in Control. 

        Subject
to the terms and conditions of the Indenture, the Company shall become obligated to repurchase, at the option of the Holder, on December 15, 2011, December 15, 2014
and December 15, 2019 (each, a "Repurchase Date"), all or a portion of the Securities held by such Holder, in any integral multiple of $1,000,
for cash at a price per Security equal to 100% of the aggregate principal amount of the Security (the "Repurchase Price"), together with accrued but
unpaid interest (including Contingent Interest and Liquidated Damages, if any) thereon, up to but not including the Repurchase Date upon delivery of a Repurchase Notice containing the information set
forth in the Indenture, together with the Securities subject thereto, at any time from the opening of business on the date that is 30 Business Days prior to such Repurchase Date until the close of
business on the Business Day
prior to such Repurchase Date, and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture. 

        At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase the Securities held by such Holder after the
occurrence of a Change in Control of the Company for a Change in Control Repurchase Price equal to 100% of the principal amount thereof plus accrued but unpaid interest (including Contingent Interest
and Liquidated Damages, if any) thereon, up to but not including the Change in Control Repurchase Date which Change in Control Repurchase Price shall be paid in cash
(provided that if the Change in Control Repurchase Date is between the close of business on a Record Date and the opening of business on the related
Interest Payment Date, accrued but unpaid interest will be payable to the Holders in whose names the Securities are registered at the close of business on the relevant Record Date). Holders have the
right to withdraw any Repurchase Notice or Change in Control Repurchase Notice, as the case 

A-6

 

may
be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. 

        If
cash sufficient to pay the Repurchase Price or Change in Control Repurchase Price, as the case may be, and accrued but unpaid interest (including Contingent Interest and Liquidated
Damages, if any) on all Securities of this series or portions thereof to be repurchased as of the Repurchase Date or the Change in Control Repurchase Date, as the case may be, is held by the Paying
Agent by 11:00 a.m., New York City time, on the Business Day immediately following the Repurchase Date or the Change in Control Repurchase Date, interest (including Contingent Interest and
Liquidated Damages, if any) shall cease to accrue on such Securities (or portions thereof) as of such Repurchase Date or Change in Control Repurchase Date, and the Holder thereof shall have no other
rights as such, other than the right to receive the Repurchase Price or Change in Control Repurchase Price, as the case may be, and interest (including Contingent Interest and Liquidated Damages, if
any) upon surrender of such Security. 

        (8)   Conversion.

        Upon
satisfaction of the conditions set forth in Section 10.01(a) of the Indenture, a Holder of a Security may convert any portion of the principal amount of any Security that is
an integral multiple of $1,000 into cash and fully paid and non-assessable shares (calculated as to each conversion to the nearest 1/10000th of a share) of Common Stock in accordance with
the provisions of Section 10.14 of the Indenture; provided that if such Security is called for redemption, the conversion right will terminate at
the close of business on the second Business Day immediately preceding the Redemption Date of such Security (unless the Company shall default in making the redemption payment when due, in which case
the conversion right shall terminate at the close of business on the date such default is cured and such Security is redeemed). Such conversion right shall commence on the initial issuance date of the
Securities and expire at the close of business on the date of maturity, subject, in the case of conversion of any Global Security, to any Applicable Procedures. The Conversion Price shall, as of the
date of the Indenture, initially be $14.47 per share of Common Stock. The Conversion Rate shall, as of the date of the Indenture, initially be approximately 69.1085. The Conversion Price and
Conversion Rate will be adjusted under the circumstances specified in the Indenture. Upon conversion, no adjustment for interest (including Contingent Interest and Liquidated Damages, if any) or
dividends will be made. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Ten Day Average Closing Stock Price (as defined in the
Indenture). Except as provided in Section 10.02(c) of the Indenture, delivery of the Principal Return, Net Shares and cash in lieu of fractional shares shall be deemed to satisfy the Company's
obligation to pay the principal amount of a converted Security and accrued but unpaid interest (including
Contingent Interest and Liquidated Damages, if any) thereon. Any accrued interest (including Contingent Interest and Liquidated Damages, if any) payable on a converted Security will be deemed paid in
full, rather than canceled, extinguished or forfeited. 

        In
addition, following certain corporate transactions as set forth in Sections 10.01(a)(iii)(A) and 10.01(a)(iii)(B) that occur on or prior to December 15, 2011 and that
constitute a Change in Control (other than relating to the composition of the Board of Directors as described in clause (d) of the definition of Change in Control in Section 1.01) and
for which 10% or more of the fair market value of the consideration for the Common Stock (as determined by the Board of Directors) in the corporate transaction consists of (i) cash,
(ii) other property or (iii) securities that are not traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange or the Nasdaq National
Market, a Holder who elects to convert its Securities in connection with such corporate transaction will be entitled to receive Additional Shares of Common Stock upon conversion in certain
circumstances. 

        To
convert a Security, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to the Conversion Agent, (b) surrender the
Security to the Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, (d) pay any transfer or other tax, if
required and (e) if the Security is held in book-entry form, complete and deliver to the Depositary appropriate instructions pursuant to the Applicable Procedures. If a Holder
surrenders a Security for conversion between the close of business on the Record Date and the opening of business on the related Interest Payment Date, the Security must be accompanied by payment of
an amount equal to the interest (including Contingent Interest and Liquidated Damages, if any) payable on such Interest Payment Date on the principal amount of the Security or portion thereof then
converted; provided that no such payment shall be required if such Security has been called for redemption on a Redemption Date within the period
between close of business on such Record Date and the opening of business on such Interest Payment Date, or if such Security 

A-7

 

is
surrendered for conversion on the Interest Payment Date. A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. 

        A
Security in respect of which a Holder has delivered a Repurchase Notice or a Change of Control Repurchase Notice exercising the option of such Holder to require the Company to
repurchase such Security as provided in Section 3.08 or Section 3.09, respectively, of the Indenture may be converted only if such notice of exercise is withdrawn in accordance with the
terms of the Indenture. 

        (9)   Denominations;
Transfer; Exchange. 

        The
Securities are in fully registered form, without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required
by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed), or any Securities in respect of which a Repurchase Notice or a Change in Control Repurchase Notice has been given and not withdrawn (except, in the case of a Security to
be repurchased in part, the portion of the Security not to be repurchased), or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 

        (10) Persons
Deemed Owners. 

        The
registered Holder of this Security may be treated as the owner of this Security for all purposes. 

        (11) Amendment;
Waiver. 

        Subject
to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in
aggregate principal amount of the Securities of this series at the time outstanding and (ii) certain defaults may be waived with the written consent of the Holders of a majority in aggregate
principal amount of the Securities of this series at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and the Trustee may
amend the Indenture or the Securities (i) to cure any ambiguity, omission, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder in any
material respect, (ii) to comply with Article 5 or Section 10.11 of the Indenture, (iii) to make provisions with respect to the conversion right of Holders pursuant to the
requirements of Section 10.01 of the Indenture, (iv) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee, or (v) to comply with
the provisions of the TIA or any requirement of the SEC in connection with the qualification of the Indenture under the TIA. 

        (12) Defaults
and Remedies. 

        Except
as set forth in the Indenture, if an Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of Securities of this series
then outstanding may declare all the Securities to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Securities of this series may not enforce the
Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received security or indemnity reasonably
satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities of this series at the time outstanding
to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of any continuing Default or Event of Default (except a default in payment of
principal or interest when due, for any reason) if it determines in good faith that withholding notice is in the interests of Holders. 

        (13) Trustee
Dealings with the Company. 

        Subject
to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not
Trustee. 

        (14) No
Recourse Against Others. 

        A
director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by 

A-8

 

reason
of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the
Securities. 

        (15) Ranking.

        The
Securities shall be unsecured senior obligations of the Company and shall rank equally in right of payment with any other existing and future senior indebtedness of the Company and
senior to any future subordinated indebtedness of the Company. 

        (16) Authentication.

        This
Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security. 

        (17) Abbreviations.

        Customary
abbreviations may be used in the name of a Holder or an assignee, such as TEN COM ("Tenants In Common"), TEN ENT
("Tenants By The Entireties"), JT TEN ("Joint Tenants With Right Of Survivorship And Not As Tenants In Common"),  CUST ("Custodian") and U/G/M/A
("Uniform Gift To Minors Act"). 

        (18) Governing
Law. 

        THE
LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS SECURITY. 

        (19) CUSIP

        Pursuant
to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a

numbers printed hereon.
