Revenue Bonds) on the Pollution Control Revenue Bonds, whether at maturity, by
tender for purchase, by acceleration, by sinking fund, redemption or otherwise,
as and when the same becomes due, the bonds of this Series shall be redeemable
in whole upon receipt by the Trustee of a written demand (hereinafter called a
"Redemption Demand") from the Pollution Control Trustee stating that there has
been such a default, stating that it is acting pursuant to the authorization
granted by Section 9.02(c) of the Pollution Control Indenture, specifying the
last date to which interest on the Pollution Control Revenue Bonds has been paid
(such date being hereinafter referred to as the "Initial Interest Accrual Date")
and demanding redemption of the bonds of this Series. The Trustee shall, within
10 days after receiving such Redemption Demand, mail a copy thereof to the
Company marked to indicate the date of its receipt by the Trustee. Promptly upon
receipt by the Company of such copy of a Redemption Demand, the Company shall
fix a date on which it will redeem the bonds of this Series so demanded to be
redeemed (hereinafter called the "Demand Redemption Date"). Notice of the date
fixed as and for the Demand Redemption Date shall be mailed by the Company to
the Trustee at least 30 days prior to such Demand Redemption Date. The date to
be fixed by the Company as and for the Demand Redemption Date may be any date up
to and including the earlier of (i) the 120th day after receipt by the Trustee
of the Redemption Demand or (ii) the Final Maturity Date, provided that if the

The Trustee shall mail notice of the Demand Redemption Date (such notice being
hereinafter called the "Demand Redemption Notice") to the Pollution Control
Trustee not more than 10 nor less than five days prior to the Demand Redemption
Date. Notwithstanding the foregoing, if a default to which this paragraph is
applicable is existing on the Final Maturity Date, such date shall be deemed to
be the Demand Redemption Date without further action (including actions
specified in this paragraph) by the Pollution Control Trustee, the Trustee or
the Company. The bonds of this Series shall be redeemed by the Company on the
Demand Redemption Date, upon surrender thereof by the Pollution Control Trustee
to the Trustee, at a redemption price equal to the principal amount thereof,
plus accrued interest thereon at the rate per annum set forth in the third
paragraph of this Bond, from the Initial Interest Accrual Date to the Demand
Redemption Date. If a Redemption Demand is rescinded by the Pollution Control
Trustee by written notice to the Trustee prior to the Demand Redemption Date, no
Demand Redemption Notice shall be given, or, if already given, shall be
automatically annulled, and interest on the bonds of this Series shall cease to
accrue, all interest accrued thereon shall be automatically rescinded and
cancelled and the Company shall not be obligated to make any payments of
principal of or interest on the bonds of this Series; but no such rescission
shall extend to or affect any subsequent default or impair any right consequent
thereon.

         In the event that all of the bonds outstanding under the Indenture
shall have become immediately due and payable, whether by declaration or
otherwise, and such acceleration shall not have been annulled, the bonds of this

that was cancelled by the Pollution Control Trustee and for which one or more
other Pollution Control Revenue Bonds were delivered and authenticated pursuant
to the Pollution Control Indenture in lieu of or in exchange or substitution for
such cancelled Pollution Control Revenue Bond), or upon provision for the

bonds "deemed to be redeemed" within the meaning of that term as used in Article
X of the Original Indenture) at, before or after the maturity thereof. On the
Release Date, the bonds of this Series shall be surrendered by the Pollution
Control Trustee to the Trustee whereupon the bonds of said Series so surrendered

present or future stockholder, officer or director of the Company or of any
predecessor or successor corporation, either directly or through the Company, or
through any such predecessor or successor corporation, or through any receiver
or trustee in bankruptcy, whether by virtue of any constitution, statute or rule
of law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released, as more fully provided in the
Indenture.

         This bond shall not be valid or become obligatory for any purpose
unless and until the certificate of authentication hereon shall have been signed
by or on behalf of Harris Trust and Savings Bank, as Trustee under the
Indenture, or its successor thereunder.

Series Y is hereinafter referred to as the Final Maturity Date. The Bonds of
Pollution Control Series Y shall bear interest from the Initial Interest Accrual
Date, as hereinafter defined, at the same rate or rates then and thereafter from
time to time borne by the Pollution Control Revenue Bonds.

         Section 2.02. Except as provided in the next succeeding paragraph of
this Section 2.02, in the event of a default under Section 9.1 of the Agreement
or in the event of a default in the payment of the principal of, premium, if
any, or interest (and such default in the payment of interest continues for the
full grace period, if any, permitted by the Pollution Control Indenture and the
Pollution Control Revenue Bonds) on the Pollution Control Revenue Bonds, whether
at maturity, by tender for purchase, by acceleration, by sinking fund,
redemption or otherwise, as and when the same becomes due, the Bonds of
Pollution Control Series Y shall be redeemable in whole upon receipt by the
Trustee of a written demand (hereinafter called a "Redemption Demand") from the
Pollution Control Trustee stating that there has been such a default, stating
that it is acting pursuant to the authorization granted by Section 9.02(c) of
the Pollution Control Indenture, specifying the last date to which interest on
the Pollution Control Revenue Bonds has been paid (such date being hereinafter
referred to as the "Initial Interest Accrual Date") and demanding redemption of
the Bonds of Pollution Control Series Y. The Trustee shall, within 10

                                       12
<PAGE>

days after receiving such Redemption Demand, mail a copy thereof to the Company
marked to indicate the date of its receipt by the Trustee. Promptly upon receipt
by the Company of such copy of a Redemption Demand, the Company shall fix a date
on which it will redeem the Bonds of Pollution Control Series Y so demanded to
be redeemed (hereinafter called the "Demand Redemption Date"). Notice of the
date fixed as the Demand Redemption Date shall be mailed by the Company to the
Trustee at least 30 days prior to such Demand Redemption Date. The date to be
fixed by the Company as and for the Demand Redemption Date may be any date up to

The Trustee shall mail notice of the Demand Redemption Date (such notice being
hereinafter called the "Demand Redemption Notice") to the Pollution Control
Trustee not more than 10 nor less than five days prior to the Demand Redemption
Date. Notwithstanding the foregoing, if a default to which this paragraph is
applicable is existing on the Final Maturity Date, such date shall be deemed to
be the Demand Redemption Date without further action (including actions
specified in this paragraph) by the Pollution Control Trustee, the Trustee or
the Company. The Bonds of Pollution Control Series Y shall be redeemed by the
Company on the Demand Redemption Date, upon surrender thereof by the Pollution
Control Trustee to the Trustee, at a redemption price equal to the principal
amount thereof, plus accrued interest thereon at the rate per annum set forth in
Section 2.01 hereof, from the Initial Interest Accrual Date to the Demand
Redemption Date. If a Redemption Demand is rescinded by the Pollution Control
Trustee by written notice to the Trustee prior to the Demand Redemption Date, no
Demand Redemption Notice shall be given, or, if already given, shall be
automatically annulled, and interest on the Bonds of Pollution Control Series Y
shall cease to accrue, all interest accrued thereon shall be automatically
rescinded and cancelled and the Company shall not be obligated to make any
payments of principal of or interest on the Bonds of Pollution Control Series Y;
but no such rescission shall extend to or affect any subsequent default or
impair any right consequent thereon.

         In the event that all of the bonds outstanding under the Indenture
shall have become immediately due and payable, whether by declaration or
otherwise, and such acceleration shall not have been annulled, the Bonds of
Pollution Control Series Y shall bear interest at the rate per annum set forth
in Section 2.01 hereof, from the Interest Accrual Date, as specified in a
written notice to the Trustee from the Pollution Control Trustee, and the
principal of and interest on the Bonds of Pollution Control Series Y from the
Initial Interest Accrual Date shall be payable in accordance with the provisions
of the Indenture.

         Anything herein contained to the contrary notwithstanding, the Trustee
is not authorized to take any action pursuant to a Redemption Demand or a
rescission thereof or a written notice required by this Section 2.02, and such
Redemption Demand, rescission or notice shall be of no force or effect, unless
it is executed in the name of the Pollution Control Trustee by one of its Vice
Presidents.

         Section 2.03.      Upon payment of the principal of and premium, if
any, and interest on the Pollution Control Revenue Bonds, whether at maturity or
prior to maturity by redemption or

otherwise, and the surrender thereof to and cancellation thereof by the
Pollution Control Trustee (other than any Pollution Control Revenue Bond that
was cancelled by the Pollution Control Trustee and for which one or more other
Pollution Control Revenue Bonds were delivered and authenticated pursuant to the
Pollution Control Indenture in lieu of or in exchange or substitution for such
cancelled Pollution Control Revenue Bond), or upon provision for the payment
thereof having been made in accordance with the Pollution Control Indenture,
Bonds of Pollution Control Series Y in a principal amount equal to the principal
amount of the Pollution Control Revenue Bonds so surrendered and cancelled or
for the provision for which payment has been made shall be deemed fully paid and
the obligations of the Company thereunder shall be terminated, and such Bonds of
Pollution Control Series Y shall be surrendered by the Pollution Control Trustee
to the Trustee and shall be cancelled and destroyed by the Trustee, and a
certificate of such cancellation and destruction shall be delivered to the
Company. From and after the Release Date (as defined below), the bonds of this
Series shall be deemed fully paid, satisfied and discharged and the obligations
of the Company hereunder and thereunder shall be terminated. The Release Date
shall be the date that the Bond Insurer (as such term is defined in the
Pollution Control Indenture), at the request of the Company, consents to the
release of the bonds of this Series as security for the Pollution Control
Revenue Bonds, provided that in no event shall that date be later than the date
as of which all bonds issued under the Indenture prior to the date of initial
issuance of this bond (and excluding bonds of this Series) have been retired
through payment, redemption or otherwise (including those bonds "deemed to be
redeemed" within the meaning of that term as used in Article X of the Original
Indenture) at, before or after the maturity thereof. On the Release Date, the
bonds of this Series shall be surrendered by the Pollution Control Trustee to
the Trustee whereupon the Bonds of said Series so surrendered shall be cancelled
by the Trustee.

         Section 2.04.      Prior to the Release Date, the Pollution Control
Trustee as the registered holder of the Bonds of Pollution Control Y at its
option may surrender the same at the office of the Trustee, in Chicago,
Illinois, or elsewhere, if authorized by the Company, for cancellation, in
exchange for other bonds of the same series of the same aggregate principal
amount. Thereupon, and upon receipt of any payment required under the provisions
of Section 2.05 hereof, the Company shall execute and deliver to the Trustee and
the Trustee shall authenticate and deliver such other registered bonds to such
registered holder at its office or at any other place specified as aforesaid.

         Section 2.05.      No charge shall be made by the Company for any
exchange or transfer of Bonds of Pollution Control Series Y other than for taxes
or other governmental charges, if any, that may be imposed in relation thereto.

                                   ARTICLE III

                                  MISCELLANEOUS

         Section 3.01. The recitals of fact herein and in the bonds (except
the Trustee's Certificate) shall be taken as statements of the Company and shall

the Indenture, or any part thereof, or as to the title of the Company

                                       14

under the Trust Indenture Act of 1939, as amended (as enacted prior to the date
of this Supplemental Indenture) by any of the provisions of Sections 310 to 317,
inclusive, of the said Act, such required provision shall control.

enforceability of the remaining provisions contained herein and therein shall
not in any way be affected, impaired, prejudiced or disturbed thereby.

         Section 3.04. Wherever in this Supplemental Indenture the word

successors and assigns of such parties, whether so expressed or not.

         Section 3.06.  (a) This Supplemental Indenture may be simultaneously
executed in several counterparts, and all said counterparts executed and
delivered, each as an original, shall constitute but one and the same
instrument.

         (b) The Table of Contents and the descriptive headings of the several
Articles of this Supplemental Indenture were formulated, used and inserted in

         This bond is one of a series of bonds of the Company issued under the

The bonds of this Series have been issued to the Pollution Control Trustee under

The bonds of this Series shall bear interest from the Initial Interest Accrual

so affected; provided that no such modification or alteration shall permit the
extension of the maturity of the principal of this bond or the reduction in the
rate of interest, if any, hereon or any other modification in the terms of
payment of such principal or interest, if any, or the taking of certain other
action as more fully set forth in the Indenture, without the consent of the

         Except as provided in the next succeeding paragraph, in the event of a
default under Section 9.1 of the Agreement or in the event of a default in the
payment of the principal of, premium, if any, or interest (and such default in
the payment of interest continues for the full grace period, if any, permitted
by the Pollution Control Indenture and the Pollution Control Revenue Bonds) on
the Pollution Control Revenue Bonds, whether at maturity, by tender for
purchase, by acceleration, by sinking fund, redemption or otherwise, as and when
the same becomes due, the bonds of this Series shall be redeemable in whole upon
receipt by the Trustee of a written demand (hereinafter called a "Redemption
Demand") from the Pollution Control Trustee stating that there has been such a
default, stating that it is acting pursuant to the authorization granted by
Section 9.02(c) of the Pollution Control Indenture, specifying the last date to
which interest on the Pollution Control Revenue Bonds has been paid (such date
being hereinafter referred to as the "Initial Interest Accrual Date") and
demanding redemption of the bonds of this Series. The Trustee shall, within 10
days after receiving such Redemption Demand, mail a copy thereof to the Company
marked to indicate the date of its receipt by the TRUSTEE. Promptly upon receipt
by the Company of such copy of a Redemption Demand, the Company shall fix a date
on which it will redeem the bonds of this Series so demanded to be redeemed
(hereinafter called the "Demand Redemption Date"). Notice of the date fixed as
and for the Demand Redemption Date shall be mailed by the Company to the Trustee
at least 30 days prior to such Demand Redemption Date. The date to be fixed by
the Company as and for the Demand Redemption Date may be any date up to and
including the earlier of (i) the 120th day after receipt by the Trustee of the
Redemption Demand or (ii) the Final Maturity Date, provided that if the Trustee
shall not have received such notice fixing the Demand Redemption Date within 90
days after receipt by it of the Redemption Demand, the Demand Redemption Date
shall be deemed to be the earlier of (i) the 120th day after receipt by the
Trustee of the Redemption Demand or (ii) the Final Maturity Date. The Trustee
shall mail notice of the Demand Redemption Date (such notice being hereinafter
called the "Demand Redemption Notice") to the Pollution Control Trustee not more
than 10 nor less than five days prior to the Demand Redemption Date.
Notwithstanding the foregoing, if a default to which this paragraph is
applicable is existing on the Final Maturity Date, such date shall be deemed to
be the Demand Redemption Date without further action (including actions
specified in this paragraph) by the Pollution Control Trustee, the Trustee or
the Company. The bonds of this Series shall be redeemed by the Company on the
Demand Redemption Date, upon surrender thereof by the Pollution Control Trustee
to the Trustee, at a redemption price equal to the principal amount thereof,
plus accrued interest thereon at the rate per annum set forth in the third
paragraph of this Bond, from the Initial Interest Accrual Date to the Demand
Redemption Date. If a Redemption Demand is rescinded by the Pollution Control
Trustee by written notice to the Trustee prior to the Demand Redemption Date, no
Demand Redemption Notice shall be given, or, if already given, shall be
automatically annulled, and interest on the bonds of this Series shall cease to
accrue, all interest accrued thereon shall be automatically rescinded and
cancelled and the Company shall not be obligated to make any payments of
principal of or interest on the bonds of this Series; but no such rescission
shall extend to or affect any subsequent default or impair any right consequent
thereon.

         In the event that all of the bonds outstanding under the Indenture
shall have become immediately due and payable, whether by declaration or
otherwise, and such acceleration shall not have been annulled, the bonds of this
Series shall bear interest at the rate per annum set forth in the third
paragraph of this bond, from the Initial Interest Accrual Date, as specified in
a

                                       8

written notice to the Trustee from the Pollution Control Trustee, and the
principal of and interest on the bonds of this Series from the Initial Interest
Accrual Date shall be payable in accordance with the provisions of the
Indenture.

         Upon payment of the principal of and premium, if any, and interest on
the Pollution Control Revenue Bonds, whether at maturity or prior to maturity by
redemption or otherwise, and the surrender thereof to and cancellation thereof
by the Pollution Control Trustee (other than any Pollution Control Revenue Bond
that was cancelled by the Pollution Control Trustee and for which one or more
other Pollution Control Revenue Bonds were delivered and authenticated pursuant
to the Pollution Control Indenture in lieu of or in exchange or substitution for
such cancelled Pollution Control Revenue Bond), or upon provision for the
payment thereof having been made in accordance with the Pollution Control
Indenture, bonds of this Series in a principal amount equal to the principal
amount of the Pollution Control Revenue Bonds so surrendered and cancelled or
for the provision for which payment has been made shall be deemed fully paid and
the obligations of the Company thereunder shall be terminated, and such bonds of
this Series shall be surrendered by the Pollution Control Trustee to the Trustee
and shall be cancelled by the Trustee. From and after the Release Date (as
defined below), the bonds of this Series shall be deemed fully paid, satisfied
and discharged and the obligations of the Company hereunder and thereunder shall
be terminated. The Release Date shall be the date that the Bond Insurer (as such
term is defined in the Pollution Control Indenture), at the request of the
Company, consents to the release of the bonds of this Series as security for the
Pollution Control Revenue Bonds, provided that in no event shall that date be
later than the date as of which all bonds issued under the Indenture prior to
the date of initial issuance of this bond (and excluding bonds of this Series
and First Mortgage Bonds, Pollution Control Series Y) have been retired through
payment, redemption or otherwise (including those bonds "deemed to be redeemed"
within the meaning of that term as used in Article X of the Original Indenture)
at, before or after the maturity thereof. On the Release Date, the bonds of this
Series shall be surrendered by the Pollution Control Trustee to the Trustee
whereupon the bonds of said Series so surrendered shall be cancelled by the
Trustee.

         No recourse shall be had for the payment of principal of, or interest,
if any, on this bond, or any part thereof, or of any claim based hereon or in
respect hereof or of the Indenture, against any incorporator, or any past,
present or future stockholder, officer or director of the Company or of any
predecessor or successor corporation, either directly or through the Company, or
through any such predecessor or successor corporation, or through any receiver
or trustee in bankruptcy, whether by virtue of any constitution, statute or rule
of law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released, as more fully provided in the
Indenture.

         This bond shall not be valid or become obligatory for any purpose
unless and until the certificate of authentication hereon shall have been signed
by or on behalf of Harris Trust and Savings Bank, as Trustee under the
Indenture, or its successor thereunder.

       Section 2.02. Except as provided in the next succeeding paragraph of this
Section 2.02, in the event of a default under Section 9.1 of the Agreement or in
the event of a default in the payment of the principal of, premium, if any, or

grace period, if any, permitted by the Pollution Control Indenture and the

rescission thereof or a written notice required by this Section 2.02, and such
Redemption Demand, rescission or notice shall be of no force or effect, unless
it is executed in the name of the Pollution Control Trustee by one of its Vice
Presidents.

       Section 2.03. Upon payment of the principal of and premium, if any, and
interest on the Pollution Control Revenue Bonds, whether at maturity or prior to
maturity by redemption or otherwise, and the surrender thereof to and
