                               REVERSE OF SECURITY

      The Trust promises to pay Distributions from November 1, 2002, or from the
most recent Distribution Date to which Distributions have been paid or duly
provided for, semi-annually (subject to deferral as set forth herein) in arrears
on May 15th and November 15th of each year, commencing on May 15, 2003, at a
variable rate per annum equal to LIBOR plus 3.35% of the Liquidation Amount of
the Preferred Securities represented by this Preferred Securities Certificate,
provided, that, the applicable Distribution Rate shall not exceed 12.0% through
the Distribution Date in November, 2007, 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 ten (10) consecutive semi-annual 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 the rate equal to
LIBOR plus 3.35% per annum (provided, that, the applicable interest rate shall
not exceed 12.0% through the Interest Payment Date in November, 2007, compounded
semiannually, 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.

<PAGE>

      During any such Extension Period, the Company shall not (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Depositor's capital stock or
(ii) make any payment of principal of or any interest or premium 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 November 15, 2007 in whole
or in part from time to time at a redemption price equal to one hundred percent
(100%) 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 the Office of Thrift Supervision if 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 a Capital Disqualification Event, an Investment Company
Event or a Tax Event at the Indenture Redemption Price.

      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.

<PAGE>

      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 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.
