the right to request redemption prior to Stated Maturity of all or part of such
interest, expressed in integral multiples of $1,000 principal amount, in the
Senior Secured Insured Quarterly Notes, and the Company will redeem the same
subject to the limitations that the Company will not be obligated to redeem,
during the period from the Original Issue Date through and including October 1,

and includes each October 1 thereafter (each such twelve-month period being
hereinafter referred to as a "Subsequent Period"),



                                       4

(i) on behalf of a deceased Beneficial Owner any interest in the Senior Secured
Insured Quarterly Notes which exceeds an aggregate principal amount of $25,000
or (ii) interests in the Senior Secured Insured Quarterly Notes in an aggregate
principal amount exceeding $3,000,000. A request for redemption may be initiated
by the Representative of a deceased Beneficial Owner at any time and in any
principal amount in integral multiples of $1,000. Representatives of deceased
Beneficial Owners must make arrangements with the Participant through whom such
interest is owned in order that timely presentation of redemption requests can
be made by the Participant to the Trustee. If the Company, although not
obligated to do so, chooses to redeem interests of any deceased Beneficial Owner
in the Senior Secured Insured Quarterly Notes in the Initial Period or any
Subsequent Period in excess of the $25,000 limitation, such redemption, to the
extent that it exceeds the $25,000 limitation for any deceased Beneficial Owner,
shall not be included in the computation of the $3,000,000 limitation for such
Initial Period or such Subsequent Period, as the case may be, or for any
succeeding Subsequent Period. Any Senior Secured Insured Note (or portion
thereof) tendered pursuant to a redemption request may be withdrawn by a written
request by the Representative received by the Trustee at least 10 days prior to
its repayment.

         Subject to the $25,000 and $3,000,000 limitations, the Company will,
after the death of any Beneficial Owner, redeem the interest of such Beneficial
Owner in the Senior Secured Insured Quarterly Notes on the next Interest Payment
Date following receipt by the Trustee of a redemption request received at least
20 days in advance of the next Interest Payment Date. The Trustee will notify
the Company promptly after receipt of any redemption request and the Company
will provide all funds necessary for such redemption prior to the date of
redemption to the Paying Agent. If redemption requests exceed the aggregate
principal amount of interests in Senior Secured Insured Quarterly Notes required
to be redeemed during the Initial Period or during any Subsequent Period, then
such excess redemption requests will be applied in the order received by the
Trustee to successive Subsequent Periods, regardless of the number of Subsequent
Periods required to redeem such interests. All redemption requests will be
redeemed in the order in which the trustee receives the redemption request. To
obtain repayment pursuant to a redemption request, the Representative must
provide to the Participant (i) a written request for repayment signed by the
Representative, and such signature must be guaranteed by a member firm of a
registered national securities exchange or of the NASD or a commercial bank or
trust company having an office or correspondent in the United States, (ii)
appropriate evidence satisfactory to the Company and the Trustee that (A) the
Representative has authority to act on behalf of the deceased Beneficial Owner,
(B) the death of such Beneficial Owner has occurred and (C) the deceased was the
owner of a beneficial interest in such Senior Secured Insured Quarterly Note at
the time of death, (iii) if applicable, a properly executed assignment or
endorsement, and (iv) if the beneficial interest in such Senior Secured Insured
Quarterly Note is held by a nominee of the deceased Beneficial Owner, a
certificate satisfactory to the Trustee from such nominee attesting to the
deceased's ownership of a beneficial interest in such Senior Secured Insured
Quarterly Note. The Participant will provide these documents to the Trustee. All
questions as to the eligibility or validity of any exercise of redemption on
behalf of a deceased Beneficial Owner will be determined by the Company, in its
sole discretion, which determinations will be final and binding on all parties.

         For purposes of this Section 5.02 an interest in Senior Secured Insured
Quarterly Notes held in tenancy by the entirety, joint tenancy or by tenants in
common will be deemed to be held by a single Beneficial Owner and the death of a
tenant by the entirety, joint tenant or tenant in common will be deemed the
death of a Beneficial Owner. The death of a Person who, during his lifetime, was
entitled to substantially all of the rights of a Beneficial Owner of an interest
in the Senior Secured Insured Quarterly Notes will be deemed the death of the
Beneficial Owner, regardless of the recordation of such interest on the records
of the Participant, if such rights can be established to the satisfaction of the
Participant and the Company.

         In the case of any redemption request which is presented pursuant to
this Section 5.02 and which has not been fulfilled at the time the Company gives
notice of its election to partially redeem Senior Secured Insured Quarterly
Notes pursuant to Section 5.01 hereof, such interest or portion thereof shall
not be subject to redemption pursuant to such Section 5.01, but shall remain
subject to redemption pursuant to this Section 5.02

paid to the holder (the "Holder") of this Note (or one or more predecessor
Notes) of record at the close of business on the regular record date (the
"Regular Record Date") for such Interest Payment Date, which, except in the case
of interest payable at the Stated Maturity (as

virtue of his having been such Holder, and may be paid to the Holder of this
Note (or one or more predecessor Notes) of record at the close of business on a
special record date (the "Special Record Date") fixed by the Company for the
payment of such defaulted interest, notice whereof shall be given to Holders not
less than 10 days prior to such Special Record Date, all as more fully provided
in the Indenture.

         Payment of the principal of this Note and the interest thereon will be
made at the office or agency of the Company in the Borough of Manhattan, City

no Global Security shall be exchangeable or transferrable.

         If an Event of Default (as defined in the Indenture) with respect to
