     The Company promises to pay interest on the principal amount of this Note
on each Interest Payment Date, as set forth below, at the rate per annum shown

     Interest will be payable semi-annually (to the holders of record of the
Notes at the close of business on the June 15 or December 15 immediately
preceding the Interest Payment Date) on each Interest Payment Date, commencing
January 1, 1999.

     Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from June 25, 1998;
provided that, if there is no existing default in the payment of interest and
this Note is authenticated between a Regular Record Date referred to on the
face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such Interest Payment Date.  Interest will be computed on the basis
of a 360-day year of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest, to the extent lawful, at a
rate per annum that is 2% in excess of the rate otherwise payable.

2.  Method of Payment.

     The Company will pay interest (except defaulted interest) on the principal
amount of the Notes as provided above on each July 1 and January 1, commencing
January 1, 1999 to the persons who are Holders (as reflected in the Security
Register at the close of business on the June 15 or December 15 immediately
preceding the Interest Payment Date), in each case, even if the Note is
cancelled on registration of transfer or registration of exchange after such
record date; provided that, with respect to the payment of principal, the
Company will make payment to the Holder that surrenders this Note to a Paying
Agent on or after July 1, 2008.

     The Company will pay principal, premium, if any, and as provided above,
interest 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
principal, premium, if any, and interest by its check payable in such money.
It may mail an interest check to a Holder's registered address (as reflected in
the Security Register).  If a payment date is a date other than a


   5



Business Day at a place of payment, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

3.  Paying Agent and Registrar.

     Initially, the Trustee will act as authenticating agent, Paying Agent and
Registrar.  The Company may change any authenticating agent, Paying Agent or

4.  Indenture; Limitations.

     The Company issued the Notes under an Indenture dated as of June 25, 1998
(the "Indenture"), between the Company and The Bank of New York, trustee (the
"Trustee").  Capitalized terms herein are used as defined in the Indenture
unless otherwise indicated.  The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the TIA.  The
Notes are subject to all such terms, and Holders are referred to the Indenture
and the TIA for a statement of all such terms.  To the extent permitted by
applicable law, in the event of any inconsistency between the terms of this
Note and the terms of the Indenture, the terms of the Indenture shall control.

     The Notes are general unsecured obligations of the Company (except as
provided in Section 15 hereof).

     Except with respect to the Exchange Notes, the Company may not issue any
additional Notes under the Indenture.

5.  Redemption Upon Receipt of Public Equity Offering Proceeds.

     At any time and from time to time prior to July 1, 2001, the Company may
redeem up to 35% of the aggregate principal amount of the Notes with the
proceeds of one or more Public Equity Offerings following which there is a
Public Market, at any time or from time to time in part, at a Redemption Price
(expressed as a percentage of principal amount) of 115%, plus accrued and
unpaid interest, if any, to the Redemption Date (subject to the rights of
Holders of record on the relevant Regular Record Date that is on or prior to
the Redemption Date to receive interest due on an Interest Payment Date);
provided that (i) at least 65% of the aggregate principal amount of Notes
originally issued remains outstanding after each such redemption and (ii)
notice of such redemption shall be mailed within 60 days of the related Public
Equity Offering.

     Notes in original denominations larger than $1,000 may be redeemed in
part.  On and after the Redemption Date, interest ceases to accrue on Notes or
portions of Notes called for redemption, unless the Company defaults in the
payment of the Redemption Price.

6.  Repurchase upon Change of Control.

     Upon the occurrence of any Change of Control, each Holder shall have the
right to require the repurchase of its Notes by the Company in cash pursuant to
the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of purchase (the "Payment Date").

     A notice of such Change of Control will be mailed within 30 days after any
Change of Control occurs to each Holder at its last address as it appears in
the Security Register.  Notes in original denominations larger than $1,000 may
be sold to the Company in part.  On and after the Payment Date, interest ceases
to accrue on Notes or portions of Notes surrendered for purchase by the
Company, unless the Company defaults in the payment of the purchase price.

7.  Denominations; Transfer; Exchange.

     The Notes are in registered form without coupons in denominations of
$1,000 of principal amount and multiples of $1,000 in excess thereof.  A Holder
may register the transfer or exchange of Notes 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 register
the transfer or exchange of any Notes selected for redemption.  Also, it need
not register the transfer or exchange of any Notes for a period of 15 days
before the day of mailing of a notice of redemption of Notes selected for
redemption.

8.  Persons Deemed Owners.

     A Holder shall be treated as the owner of a Note for all purposes.

9.  Unclaimed Money.

     If money for the payment of principal, premium, if any, or interest
remains unclaimed for two years, the Trustee and the Paying Agent will pay the
money back to the Company at its written request.  After that, Holders entitled
to the money must look to the Company for payment, unless an abandoned property
law designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

10.  Discharge Prior to Redemption or Maturity.

     If the Company deposits with the Trustee cash, Temporary Cash Investments
or U.S. Government Obligations sufficient to pay the then outstanding principal
of, premium, if any, and accrued interest on the Notes (a) to redemption or
maturity, the Company will be discharged from the Indenture and the Notes,

forth in the Indenture, provided that if, simultaneously with the deposit of
the cash or Temporary Cash Investments and/or U.S. Government Obligations

credit to be issued by a bank with capital and surplus exceeding the principal
of, premium, if any, and interest on the Notes then outstanding, expiring not
earlier than 180 days from its issuance, in favor of the Trustee, which permits
the Trustee to draw an amount equal to the principal, premium, if any, and
accrued interest on the Notes through the expiry date of the letter of credit,
then the Company will be deemed to have paid and discharged any and all
obligations under this clause on the date of the deposit and issuance of the
letter of credit.

11.  Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Indenture, the Pledge Agreement or the
Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding, and any
existing default or compliance with any provision may be waived with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding.  Without notice to or the consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency and make any change that
does not materially and adversely affect the rights of any Holder.
