                       9.20% SENIOR SECURED BOND SERIES B

                                    DUE 2029

     This bond is one of an issue of bonds of the Company, issuable in series,
and is one of a series known as its 9.20% Senior Secured Bonds Series B Due 2029
(collectively, the "BONDS"), all issued and to be issued under and equally
secured (except as to any sinking fund established in accordance with the
provisions of the Indenture hereinafter mentioned for the bonds of any
particular series) by a Trust Indenture, dated as of March 1, 2000, executed and
delivered between the Company and The Bank of New York, as Trustee and
Depositary Bank (the "ORIGINAL INDENTURE"), as amended and supplemented by the
First Supplemental Indenture, dated as of March 1, 2000, to which the Original
Indenture is so amended and supplemented (herein collectively referred to as the
"INDENTURE"). A description of the rights of the Bondholders and the terms and
conditions upon which the Bonds are issued are set forth in the Indenture.
Capitalized terms used but not otherwise defined herein shall have the meanings
assigned thereto in the Indenture.

     THE BONDS ARE SUBJECT TO OPTIONAL AND MANDATORY REDEMPTION AND PREPAYMENT
AS PROVIDED IN THE INDENTURE.

     As more fully described in the Indenture, the Company has the right,
without the consent by Holders of the Bonds, to amend the Indenture in certain
respects of the Bondholders. As more fully described in the Indenture, with the
consent of Bondholders of not less than a majority in aggregate principal amount
of the Bonds of all series then Outstanding, the Company may amend the Indenture
in any other respect; provided, however, that no amendment shall, without the
consent of the Holder of each Outstanding Bond, (1) change the maturity date of
any Bond, or change the amount, of any payment of principal, interest or
premium, if any, on any Bond, (2) permit the creation of any lien on the
Collateral not otherwise permitted, prior to or on a parity with the lien of the
Indenture, or terminate the lien of the Indenture, (3) reduce the percentage of
the principal amount of Bonds the Holders of which are required to approve any
such amendment or (4) waive a Default in the payment of principal, interest or
premium, if any, or the remedies available in the case of an Event of Default.

     The principal hereof may be declared or may become due on the conditions,
in the manner and at the time set forth in the Indenture, including an
acceleration of payment of the principal upon the occurrence and during the
continuance of an Event of Default as in the Indenture provided.

     Recourse under this Bond is limited as set forth under the Indenture.
Satisfaction of the obligations of the Company under this Indenture, for the
payment of the principal of or premium, if any, or interest on any Bonds, or any
part thereof, or for any claim based thereon or otherwise in respect thereof or
related thereto, shall be had solely from the Collateral and the assets of the
Company and no recourse shall be had in the event of any non-performance by the
Company of


                                       4
<PAGE>

any such obligations to (i) any assets or properties of the Members (or any
Person that controls any Member within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) or (ii) any Affiliate of the
Company or any incorporators, officers, directors or employees thereof, and no
judgment for any deficiency upon the obligations of the Company under this
Indenture, for the payment of the principal of or premium, if any, or interest
on any Bonds, or any part thereof, or for any claim based thereon or otherwise
in respect thereof or related thereto, shall be obtainable by the Bondholders or
the Trustee against any Member or Affiliate of the Company or any other
incorporator, stockholder, officer, employee or director, past, present or
future of the Company or any Affiliate of the Company; PROVIDED, HOWEVER, that
nothing contained herein shall prevent the taking of any action permitted by law
against the Company or any of its Affiliates, or in any way affect or impair the
rights of the Trustee or Bondholders to take any action permitted by law, in
either case to realize upon the collateral and, PROVIDED FURTHER, that nothing
herein shall be deemed to affect the obligations of any Affiliate of the Company
under any Transaction Document to which such Affiliate is a party.

     The Bonds are issuable only as registered bonds without coupons in
denominations of $100,000 and integral multiples of $1,000 in excess thereof and
authorized multiples thereof. This Bond is transferable as prescribed in the
Indenture by the registered owner hereof, in person or by attorney duly
authorized, at the Corporate Trust Office of the Trustee, upon surrender and
cancellation of this Bond, and thereupon a new registered Bond or Bonds for a
like principal amount in authorized denominations will be issued to the
transferee in exchange therefor, as provided in the Indenture, and upon payment,
if the Company shall require it, of the transfer charges therein prescribed. The
Company and the Trustee shall deem and treat the person in whose name this Bond
is registered as the absolute owner for the purpose of receiving payment of or
on account of the principal and interest due hereon and for all other purposes.
Registered Bonds shall be exchangeable at said office of the Trustee for
registered Bonds of other authorized denominations having the same aggregate
principal amount, in the manner and upon the conditions prescribed in the
Indenture. Notwithstanding any provision of the Indenture, (a) neither the
Company nor the Trustee shall be required to make transfers or exchanges of
Bonds during the period between any interest payment date for such Bonds and the
Regular Record Date next preceding such interest payment date, and (b) no charge
shall be made upon any transfer or exchange of Bonds other than for any tax or
taxes or other government charges required to be paid by the Company.

     All payments of principal and interest with respect to certificated Bonds
will be made by dollar check drawn on a bank in The City of New York or, for
Bondholders of at least U.S.$1,000,000 in aggregate principal amount of Bonds,
by wire transfer to a dollar account maintained by the payee with a bank in the
United States; PROVIDED, that a written request from such Bondholder to such
effect designating such account is received by the Trustee or the Paying Agent
no later than the Regular Record Date immediately preceding such Bond Payment
Date. Unless such designation is revoked, any such designation made by such
person with respect to such certificated Bonds will remain in effect with
respect to any future payments with respect to such certificated Bond payable to
such person.
