                              [REVERSE OF SECURITY]

     The Trust promises to pay Distributions from February 22, 2006, or from the
most recent Distribution Date to which Distributions have been paid or duly
provided for, quarterly (subject to deferral as set forth herein) in arrears on
March 15, June 15, September 15 and December 15 of each year, commencing on
March 15, 2006, at a fixed rate equal to 8.70% per annum through the interest
payment date in March 2011 and thereafter at a variable rate per annum equal to
LIBOR plus 3.64% of the Liquidation Amount of the Preferred Securities
represented by this Preferred Securities Certificate, together with any
Additional Interest Amounts, in respect to such period.

     Distributions on the Trust Securities shall be made by the Paying Agent
from the Payment Account and shall be payable on each Distribution Date only to
the extent that the Trust has funds then on hand and available in the Payment
Account for the payment of such Distributions.

     In the event (and to the extent) that the Depositor exercises its right
under the Indenture to defer the payment of interest on the Notes, Distributions
on the Preferred Securities shall be deferred.

     Under the Indenture, so long as no Note Event of Default has occurred and
is continuing, the Depositor shall have the right, at any time and from time to
time during the term of the Notes, to defer the payment of interest on the Notes
for a period of up to twenty (20) consecutive quarterly interest payment periods
(each such extended interest payment period, an "Extension Period"), during
which Extension Period no interest shall be due and payable (except any
Additional Tax Sums that may be due and payable). No interest on the Notes shall
be due and payable during an Extension Period, except at the end thereof, but
each installment of interest that would otherwise have been due and payable
during such Extension Period shall bear Additional Interest (to the extent
payment of such interest would be legally enforceable) at a fixed rate equal to
8.70% per annum through the interest payment date in March 2011 and thereafter
at a variable rate equal to LIBOR plus 3.64% per annum compounded quarterly,
from the dates on which amounts would have otherwise been due and payable until
paid or until funds for the payment thereof have been made available for
payment. If Distributions are deferred, the deferred Distributions (including
Additional Interest Amounts) shall be paid on the date that the related
Extension Period terminates to Holders (as defined in the Trust Agreement) of
the Trust Securities as they appear on the books and records of the Trust on the
record date immediately preceding such termination date.

     Distributions on the Securities must be paid on the dates payable (after
giving effect to any Extension Period) to the extent that the Trust has funds
available for the payment of such Distributions in the Payment Account of the
Trust. The Trust's funds available for Distribution to the Holders of the
Preferred Securities will be limited to payments received from the Depositor.
The payment of Distributions out of moneys held by the Trust is guaranteed by
the Depositor pursuant to the Guarantee Agreement.

     During any such Extension Period, the Depositor shall not (i) declare or
pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with

<PAGE>

respect to, any of the Depositor's capital stock or (ii) make any payment of
principal of or any interest or premium, if any, on or repay, repurchase or
redeem any debt securities of the Depositor that rank pari passu in all respects
with or junior in interest to the Notes (other than (a) repurchases, redemptions
or other acquisitions of shares of capital stock of the Depositor in connection
with (1) any employment contract, benefit plan or other similar arrangement with
or for the benefit of any one or more employees, officers, directors or
consultants, (2) a dividend reinvestment or stockholder stock purchase plan or
(3) the issuance of capital stock of the Depositor (or securities convertible
into or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Depositor's
capital stock (or any capital stock of a Subsidiary (as defined in the
Indenture) of the Depositor) for any class or series of the Depositor's capital
stock or of any class or series of the Depositor's indebtedness for any class or
series of the Depositor's capital stock, (c) the purchase of fractional
interests in shares of the Depositor's capital stock pursuant to the conversion
or exchange provisions of such capital stock or the security being converted or
exchanged, (d) any declaration of a dividend in connection with any Rights Plan
(as defined in the Indenture), the issuance of rights, stock or other property
under any Rights Plan, or the redemption or repurchase of rights pursuant
thereto or (e) any dividend in the form of stock, warrants, options or other
rights where the dividend stock or the stock issuable upon exercise of such
warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock).

     On each Note Redemption Date, on the stated maturity (or any date of
principal repayment upon early maturity) of the Notes and on each other date on
(or in respect of) which any principal on the Notes is repaid, the Trust will be
required to redeem a Like Amount of Trust Securities at the Redemption Price.
Under the Indenture, the Notes may be redeemed by the Depositor on any Interest
Payment Date, at the Depositor's option, on or after March 15, 2011 in whole or
in part from time to time at the Optional Note Redemption Price of the principal
amount thereof or the redeemed portion thereof, as applicable, together, in the
case of any such redemption, with accrued interest, including any Additional
Interest, to but excluding the date fixed for redemption; provided, that the
Depositor shall have received the prior approval of any Applicable Insurance
Regulatory Authority then required. The Notes may also be redeemed by the
Depositor, at its option, at any time, in whole but not in part, upon the
occurrence of an Investment Company Event or a Tax Event at the Special Note
Redemption Price; provided, that the Depositor shall have received the prior
approval of any Applicable Insurance Regulatory Authority then required; and
provided, further, that such Investment Company Event or a Tax Event is
continuing on the Redemption Date.

     The Trust Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the proceeds from the contemporaneous redemption or
payment at maturity of Notes. Redemptions of the Trust Securities (or portion
thereof) shall be made and the Redemption Price shall be payable on each
Redemption Date only to the extent that the Trust has funds then on hand and
available in the Payment Account for the payment of such Redemption Price.

Payments of Distributions (including any Additional Interest Amounts), the
Redemption Price, Liquidation Amount or any other amounts in respect of the
Preferred Securities shall be made by wire transfer at such place and to such
account at a banking institution in the United

<PAGE>

States as may be designated in writing at least ten (10) Business Days prior to
the date for payment by the Person entitled thereto unless proper written
transfer instructions have not been received by the relevant record date, in
which case such payments shall be made by check mailed to the address of such
Person as such address shall appear in the Security Register. If any Preferred
Securities are held by a Depositary, such Distributions shall be made to the
Depositary in immediately available funds.

     The indebtedness evidenced by the Notes is, to the extent provided in the
Indenture, subordinate and junior in right of payment to the prior payment in
full of all Senior Debt (as defined in the Indenture), and this Security is
issued subject to the provisions of the Indenture with respect thereto.
