              Mortgage Bond, Pledge Series A of 2000 due 2033


          This bond is one of an issue of bonds of the Company, issuable
in series, and is one of a series known as its Mortgage Bonds of the
series designated in its title, all issued and to be issued under and
equally secured (except as to any money, obligations or other instruments,
or earnings thereon, deposited with the Trustee or sinking fund
established in accordance with the provisions of the Indenture hereinafter
mentioned for the bonds of any particular series) by a General Mortgage
Indenture and Deed of Trust, dated as of January 1, 1998, executed by the
Company to The Bank of New York, as Trustee, as supplemented by indentures
supplemental thereto, to which Indenture as so supplemented (herein
referred to as the "Indenture") reference is made for a description of the
property mortgaged and pledged, the nature and extent of the security, the
rights of the holders of the bonds in respect thereof and the terms and
conditions upon which the bonds are secured.

          The bonds of this series are issued and to be issued in order to
provide security to the Insurer in connection with its issuance of a
municipal bond insurance policy (the "Policy") in favor of the holder of
the Authority Bonds pursuant to the Insurance Agreement (the "Insurance
Agreement") dated as of April 1, 2000 between the Insurer and the Company.
In order to provide monies to fund a loan made by the Authority to the
Company pursuant to a Waste Water Facilities and Solid Waste Facilities
Loan Agreement dated as of April 1, 2000 between the Authority and the
Company (the "Loan Agreement"), the Authority has issued the Authority
Bonds under and pursuant to the Authority Indenture. Payments made by the
Company of principal and interest on the bonds of this series are intended
to be sufficient to reimburse the Insurer for any payments of principal
and interest made by the Insurer on the Authority Bonds pursuant to the
Policy.

          The bonds of this series are not transferable except (i) as
required to effect an assignment to a successor of the Insurer under the
Insurance Agreement or (ii) in compliance with a final order of a court of
competent jurisdiction in connection with any bankruptcy or reorganization
proceeding of the Company.

          The Company's obligation to make payments with respect to the
principal of and/or interest on the bonds of this series shall be fully or
partially satisfied and discharged to the extent that, at the time any
such payment shall be due, the corresponding amount then due of principal
of and/or interest on the Authority Bonds shall have been fully or
partially paid (other than by the application of the proceeds of any
payment by the Insurer under the Policy), as the case may be, or there
shall have been deposited with the Authority Trustee pursuant to the
Authority Indenture trust funds sufficient under such indenture to fully
or partially pay, as the case may be, the corresponding amount then due of
principal of and/or interest on the Authority Bonds (other than by the
application of the proceeds of any payment by the Insurer under the
Policy).  Notwithstanding anything contained herein or in the Indenture to
the contrary, the Company shall be obligated to make payments with respect
to the principal of and/or interest on the bonds of this series only to
the extent that the Insurer has made a payment with respect to the
Authority Bonds under the Policy.

          Upon payment of the principal of and interest due on the
Authority Bonds, whether at maturity or prior to maturity by acceleration,
redemption or otherwise, or upon provision for the payment thereof having
been made in accordance with the Authority Indenture (other than by the
application of the proceeds of any payment by the Insurer under the
Policy), the bonds of this series in a principal amount equal to the
principal amount of Authority Bonds so paid or for which such provision
for payment has been made shall be deemed fully paid, satisfied and
discharged and the obligations of the Company thereunder shall be
terminated and such bonds of this series shall be surrendered to and
canceled by the Trustee. From and after the Release Date (as defined in
the Insurance Agreement), the bonds of this series shall be deemed fully
paid, satisfied and discharged and the obligation of the Company
thereunder shall be terminated. On the Release Date, the bonds of this
series shall be surrendered to and canceled by the Trustee.

          The bonds of this series are subject to mandatory redemption, in
whole or in part, as the case may be, on each date that Authority Bonds
are to be redeemed.  The principal amount of the Bonds of this series to
be redeemed on any such date shall be equal to the principal amount of
Authority Bonds called for redemption on that date.  All redemptions of
bonds of this series shall be at 100% of the principal amount thereof,
plus accrued interest to the redemption date.

          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, upon
the occurrence of an Event of Default as in the Indenture provided.

          No recourse shall be had for the payment of the principal of or
premium, or interest if any, on this bond, or any part thereof, or for any
claim based thereon or otherwise in respect thereof, or of the
indebtedness represented thereby, or upon any obligation, covenant or
agreement under the Indenture, against any incorporator, stockholder,
officer or director, as such, past, present or future of the Company or of
any predecessor or successor corporation, either directly or through the
Company or a predecessor or successor corporation, whether by virtue of
any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability
of incorporators, stockholders, officers and directors being released by
the registered owner hereof by the acceptance of this bond and being
likewise waived and released by the terms of the Indenture.

          The bonds of this series are issuable only as registered bonds
without coupons in denominations of $1,000 and authorized multiples
thereof. This bond, subject to the limitations with regard thereto in the
Authority Indenture and herein, is transferable as prescribed in the
Indenture by the registered owner hereof, in person or by attorney duly
authorized, at an office or agency of the Company, in the Borough of
Manhattan, The City of New York, New York or in the City of Akron, Ohio,

registered bond or bonds of the same series 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 may deem and treat the person in whose name this bond is
registered as the absolute owner for the purpose of receiving payment of

purposes. Bonds of this series shall be exchangeable at said offices or

             Mortgage Bond, Pledge Series B of 2000 due 2033


          This bond is one of an issue of bonds of the Company, issuable
in series, and is one of a series known as its Mortgage Bonds of the
series designated in its title, all issued and to be issued under and
equally secured (except as to any money, obligations or other instruments,
or earnings thereon, deposited with the Trustee or sinking fund
established in accordance with the provisions of the Indenture hereinafter
mentioned for the bonds of any particular series) by a General Mortgage
Indenture and Deed of Trust, dated as of January 1, 1998, executed by the
Company to The Bank of New York, as Trustee, as supplemented by indentures
supplemental thereto, to which Indenture as so supplemented (herein
referred to as the "Indenture") reference is made for a description of the
property mortgaged and pledged, the nature and extent of the security, the
rights of the holders of the bonds in respect thereof and the terms and
conditions upon which the bonds are secured.

          The bonds of this series are issued and to be issued in order to
provide security to the Insurer in connection with its issuance of a
municipal bond insurance policy (the "Policy") in favor of the holders of
the Authority Bonds pursuant to the Insurance Agreement (the "Insurance
Agreement") dated as of April 1, 2000 between the Insurer and the Company.
In order to provide monies to fund a loan made by the Authority to the
Company pursuant to an Air Quality Facilities Loan Agreement dated as of
April 1, 2000 between the Authority and the Company (the "Loan
Agreement"), the Authority has issued the Authority Bonds under and
pursuant to the Authority Indenture. Payments made by the Company of
principal and interest on the bonds of this series are intended to be
sufficient to reimburse the Insurer for any payments of principal and
interest made by the Insurer on the Authority Bonds pursuant to the
Policy.

          The bonds of this series are not transferable except (i) as
required to effect an assignment to a successor of the Insurer under the
Insurance Agreement or (ii) in compliance with a final order of a court of
competent jurisdiction in connection with any bankruptcy or reorganization
proceeding of the Company.

          The Company's obligation to make payments with respect to the
principal of and/or interest on the bonds of this series shall be fully or
partially satisfied and discharged to the extent that, at the time any
such payment shall be due, the corresponding amount then due of principal
of and/or interest on the Authority Bonds shall have been fully or
partially paid (other than by the application of the proceeds of any
payment by the Insurer under the Policy), as the case may be, or there
shall have been deposited with the Authority Trustee pursuant to the
Authority Indenture trust funds sufficient under such indenture to fully
or partially pay, as the case may be, the corresponding amount then due of

Bonds (other than by the application of the proceeds of any payment by the
Insurer under the Policy). Notwithstanding anything contained herein or in
the Indenture to the contrary, the Company shall be obligated to make
payments with respect to the principal of and/or interest on the bonds of
this series only to the extent that the Insurer has made a payment with
respect to the Authority Bonds under the Policy.

          Upon payment of the principal of and interest due on the
Authority Bonds, whether at maturity or prior to maturity by acceleration,
redemption or otherwise, or upon provision for the payment thereof having
been made in accordance with the Authority Indenture (other than by the
application of the proceeds of any payment by the Insurer under the
Policy), the bonds of this series in a principal amount equal to the
principal amount of Authority Bonds so paid or for which such provision
for payment has been made shall be deemed fully paid, satisfied and
discharged and the obligations of the Company thereunder shall be
terminated and such bonds of this series shall be surrendered to and
canceled by the Trustee. From and after the Release Date (as defined in
the Insurance Agreement), the bonds of this series shall be deemed fully
paid, satisfied and discharged and the obligation of the Company
thereunder shall be terminated. On the Release Date, the bonds of this
series shall be surrendered to and canceled by the Trustee.

          The bonds of this series are subject to mandatory redemption, in
whole or in part, as the case may be, on each date that Authority Bonds
are to be redeemed. The principal amount of the Bonds of this series to be
redeemed on any such date shall be equal to the principal amount of
Authority Bonds called for redemption on that date. All redemptions of
bonds of this series shall be at 100% of the principal amount thereof,
plus accrued interest to the redemption date.

          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, upon
the occurrence of an Event of Default as in the Indenture provided.

          No recourse shall be had for the payment of the principal of or
premium, or interest if any, on this bond, or any part thereof, or for any
claim based thereon or otherwise in respect thereof, or of the
indebtedness represented thereby, or upon any obligation, covenant or
agreement under the Indenture, against any incorporator, stockholder,
officer or director, as such, past, present or future of the Company or of
any predecessor or successor corporation, either directly or through the
Company or a predecessor or successor corporation, whether by virtue of
any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability
of incorporators, stockholders, officers and directors being released by
the registered owner hereof by the acceptance of this bond and being
likewise waived and released by the terms of the Indenture.

          The bonds of this series are issuable only as registered bonds
without coupons in denominations of $1,000 and authorized multiples
thereof. This bond, subject to the limitations with regard thereto in the
Authority Indenture and herein, is transferable as prescribed in the

Bonds (other than by the application of the proceeds of any payment by the
Insurer under the Policy). Notwithstanding anything contained herein or in
the Indenture to the contrary, the Company shall be obligated to make
payments with respect to the principal of and/or interest on the bonds of
this series only to the extent that the Insurer has made a payment with
respect to the Authority Bonds under the Policy.

          Upon payment of the principal of and interest due on the
Authority Bonds, whether at maturity or prior to maturity by acceleration,
redemption or otherwise, or upon provision for the payment thereof having
been made in accordance with the Authority Indenture (other than by the
application of the proceeds of any payment by the Insurer under the
Policy), the bonds of this series in a principal amount equal to the
principal amount of Authority Bonds so paid or for which such provision
for payment has been made shall be deemed fully paid, satisfied and
discharged and the obligations of the Company thereunder shall be
terminated and such bonds of this series shall be surrendered to and
canceled by the Trustee. From and after the Release Date (as defined in
the Insurance Agreement), the bonds of this series shall be deemed fully
paid, satisfied and discharged and the obligation of the Company
thereunder shall be terminated. On the Release Date, the bonds of this
series shall be surrendered to and canceled by the Trustee.

          The bonds of this series are subject to mandatory redemption, in
whole or in part, as the case may be, on each date that Authority Bonds
are to be redeemed. The principal amount of the Bonds of this series to be
redeemed on any such date shall be equal to the principal amount of
Authority Bonds called for redemption on that date. All redemptions of
bonds of this series shall be at 100% of the principal amount thereof,
plus accrued interest to the redemption date.

          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, upon
the occurrence of a completed Event of Default as in the Indenture
provided.

          No recourse shall be had for the payment of the principal of or
premium, or interest if any, on this bond, or any part thereof, or for any
claim based thereon or otherwise in respect thereof, or of the
indebtedness represented thereby, or upon any obligation, covenant or
agreement under the Indenture, against any incorporator, stockholder,
officer or director, as such, past, present or future of the Company or of
any predecessor or successor corporation, either directly or through the
Company or a predecessor or successor corporation, whether by virtue of
any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability
of incorporators, stockholders, officers and directors being released by
the registered owner hereof by the acceptance of this bond and being
likewise waived and released by the terms of the Indenture.

          The bonds of this series are issuable only as registered bonds
without coupons in denominations of $1,000 and authorized multiples
thereof. This bond, subject to the limitations with regard thereto in the
Authority Indenture and herein, is transferable as prescribed in the
Indenture by the registered owner hereof, in person or by attorney duly
authorized, at an office or agency of the Company, in the Borough of
Manhattan, The City of New York, New York or in


                                - 21 -


<PAGE>

the City of Akron, Ohio, upon surrender and cancellation of this bond and
thereupon a new registered bond or bonds of the same series 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 may 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. Bonds of this series shall be
exchangeable at said offices or agencies of the Company for registered
bonds of other authorized denominations having the same aggregate
principal amount, in the manner and upon the conditions prescribed in the
Indenture.

              [End of Form of Bond of Pledge Series D]

and

          Whereas, all things necessary to make the bonds of the 2000
Pledge Series, when authenticated by the Trustee and issued as in the
Indenture provided, the valid, binding and legal obligations of the
Company, entitled in all respects to the security of the Indenture, have
been done and performed, and the creation, execution and delivery of this
Supplemental Indenture has in all respects been duly authorized; and

          Whereas, the Company deems it advisable to enter into this
Supplemental Indenture for the purposes of describing the bonds of the
2000 Pledge Series and establishing the respective forms, terms and
provisions thereof, as provided and contemplated by sections 2.01(a) and
3.01(b) of the Indenture, and the Company has requested and hereby
requests the Trustee to join in the execution of this Supplemental
Indenture;

          Now, therefore, It is hereby covenanted, declared and agreed, by
and between the Company and the Trustee, that all such bonds of the 2000
Pledge Series are to be issued, authenticated and delivered, subject to
this Supplemental Indenture, and to the further covenants, conditions,
uses and trusts in the Indenture set forth, and the parties hereto
mutually agree as follows:

          Section 1. Bonds of the 2000 Pledge Series shall mature on the
date set forth in the respective form of bond relating thereto
hereinbefore set forth and, subject to the provisions of said form, shall
bear interest at the rate from time to time borne by the applicable
Authority Bonds; provided, however, that in no event shall the rate of
                 -----------------
interest borne by any bonds of the 2000 Pledge Series exceed 10% per
annum. Such interest shall be payable as set forth in said forms of bond
of the 2000 Pledge Series, and such bonds of said series shall be
designated as hereinbefore in the seventh Whereas clause set forth. Both
principal of and interest on said bonds shall be payable, to the extent
specified in the respective form of bond hereinabove set forth, in any
coin or currency of the United States of America which at the time of
payment is a coin or currency in which the Authority Bonds are payable and
is legal tender for the payment of public and private debts, at the office
or agency of the Company in the Borough of Manhattan, The City of New
York, New York. Definitive bonds of said series may be issued, originally
or otherwise, only as registered bonds without coupons; and they and the
Trustee's certificate of


                                - 22 -


<PAGE>


authentication shall be substantially in the forms hereinbefore recited,
respectively.

          Definitive bonds of the 2000 Pledge Series may be issued,
originally or otherwise, only as registered bonds, substantially in the
respective form of bond hereinabove recited, and in denominations of
$1,000 and authorized multiples thereof. Delivery of a bond of the 2000
Pledge Series to the Trustee for authentication shall be conclusive
evidence that the multiple thereof and its serial number has been duly
approved by the Company.

          The bonds of the 2000 Pledge Series shall be redeemable as
provided in the respective form of bond hereinabove set forth, and such
provisions are incorporated at this place as though set forth in their
entirety.

          Except as provided in this Section 1, bonds of the 2000 Pledge
Series shall be dated and bear interest as provided in Section 3.03 of the
Indenture; provided, however, that, notwithstanding any provision of said
Section 3.03, so long as there is no existing default in the payment of
interest on said bonds, any bond of the 2000 Pledge Series authenticated
by the Trustee between an Interest Payment Date for bonds of such series
and the Regular Record Date for such interest payment date shall bear
interest from such interest payment date and the holder of any such bond
shall not be entitled to payment of interest on such interest payment date
and shall have no claim against the Company with respect thereto.

          Bonds of the 2000 Pledge Series may be transferred by the
registered owners thereof, in person or by attorney duly authorized, at an
office or agency of the Company in the Borough of Manhattan, The City of
New York, New York or in the City of Akron, Ohio but only in the manner
and upon the conditions prescribed in the Indenture and in the respective
form of bond of such series hereinabove recited.

          The person in whose name any bond of the 2000 Pledge Series is
registered at the close of business on any record date for such series
with respect to any interest payment date for such series shall be
entitled to receive the interest payable on such interest payment date
notwithstanding the cancellation of such registered bond upon any transfer
or exchange thereof subsequent to the record date and prior to such
interest payment date, except if and to the extent the Company shall
default in the payment of the interest due on such interest payment date,
in which case such defaulted interest shall be paid to the person in whose
name such bond (or any bond or bonds issued, directly or after
intermediate transactions, upon transfer or exchange or in substitution
thereof) is registered on a subsequent record date for such payment
established as provided in Section 3.07 of the Indenture.

          Notices and demands to or upon the Company in respect of the
bonds of the 2000 Pledge Series and the Indenture may be served at the
office or agency of the Company maintained for that purpose in the Borough
of Manhattan, The City of New York, NY and in the City of Akron, Ohio.

          Section 2. As more fully set forth in the respective form
thereof hereinabove recited, the Company's obligation to make payments
with respect to the principal of and/or interest on any bond of the 2000
Pledge Series shall be fully or partially satisfied and discharged


                                - 23 -


<PAGE>


to the extent that, at the time any such payment shall be due, the
corresponding amount then due of principal of and/or interest then due on
the applicable Authority Bond shall have been fully or partially paid
(other than by the application of the proceeds of any payment by the
Insurer under the applicable Policy), as the case may be, or there shall
have been deposited with the Authority Trustee pursuant to the applicable
Authority Indenture trust funds sufficient under such indenture to fully
or partially pay, as the case may be, the corresponding amount then due of
principal of and/or interest on the applicable Authority Bonds (other than
by the application of the proceeds of any payment by the Insurer under the
applicable Policy). Notwithstanding anything contained herein or in the
Indenture to the contrary, the Company shall be obligated to make payments
with respect to the principal of and/or interest on the bonds of the 2000
Pledge Series only to the extent that the Insurer has made a payment with
respect to the applicable Authority Bonds under the Policy.

          Upon payment of the principal of and interest due on the
applicable Authority Bonds, whether at maturity or prior to maturity by
acceleration, redemption or otherwise, or upon provision for the payment
thereof having been made in accordance with the applicable Authority
Indenture (other than by the application of the proceeds of any payment by
the Insurer under the applicable Policy), bonds of the 2000 Pledge Series
in a principal amount equal to the principal amount of the applicable
Authority Bonds so paid or for which such provision for payment has been
made shall be deemed fully paid, satisfied and discharged and the
obligations of the Company thereunder shall be terminated and such bonds
of the 2000 Pledge Series shall be surrendered to and cancelled by the
Trustee. From and after the Release Date (as defined in the applicable
Insurance Agreement), the bonds of the 2000 Pledge Series shall be deemed
fully paid, satisfied and discharged and the obligation of the Company
thereunder shall be terminated. On the Release Date, the bonds of the 2000
Pledge Series shall be surrendered to and canceled by the Trustee.

          The Trustee may conclusively presume that the obligation of the
Company to pay the principal of, and interest, if any on the bonds of the
2000 Pledge Series as the same shall become due and payable shall have
been fully satisfied  and discharged unless and until it shall have
received written notice from the Insurer, signed by an authorized officer
thereof, stating that the Insurer is exercising its rights under the
applicable Insurance Agreement with respect to the bonds of the 2000
Pledge Series.

          Section 3.  Except as herein otherwise expressly provided, no
duties, responsibilities or liabilities are assumed, or shall be construed
to be assumed, by the Trustee by reason of this Supplemental Indenture;
the Trustee shall not be responsible in any manner whatsoever for or in
respect of the validity or sufficiency of this Supplemental Indenture or
for or in respect of the recitals herein or in the respective bonds
(except the Trustee's authentication certificate), all of which are made
by the Company solely; and this Supplemental Indenture is executed and
accepted by the Trustee, subject to all the terms and conditions set forth
in the Indenture, as fully to all intents and purposes as if the terms and
conditions of the Indenture were herein set forth at length.

          Section 4.  The principal amount of bonds of Pledge Series A
which may be authenticated and delivered hereunder is limited to the
aggregate principal amount of Forty-four


                                - 24 -


Million Eight Hundred Thousand Dollars ($44,800,000). The principal amount

Dollars ($19,000,000). The principal amount of bonds of Pledge Series D

          Bonds of the 2000 Pledge Series in the aggregate principal
amount of One Hundred Thirty-six Million Five Hundred Thousand Dollars
($136,500,000) may at any time subsequent to the execution hereof be
executed by the Company and delivered to the Trustee and shall be
authenticated by the Trustee and delivered (either before or after the
recording hereof) pursuant to a Company Order referred to in Section 4.01
of the Indenture and upon receipt by the Trustee of the opinions and other
documents required by Section 4.02 of the Indenture.

          Section 5.  The consideration for the bonds of the 2000 Pledge
Series shall be the issuance by the Insurer of each respective Policy
pursuant to the applicable Insurance Agreement.

          Section 6.  As supplemented by this Supplemental Indenture, the
Indenture is in all respects ratified and confirmed, and the Indenture as
herein defined, and this Supplemental Indenture, shall be read, taken and
construed as one and the same instrument. Capitalized terms used but not
defined herein shall have the meanings ascribed to them in the Original
Indenture.

          Section 7.  Nothing in this Supplemental Indenture contained
shall or shall be construed to confer upon any person other than a holder
of bonds issued under the Indenture, the Company and the Trustee any right
or interest to avail himself of any benefit under any provision of the
Indenture or of this Supplemental Indenture.

          Section 8.  This Supplemental Indenture may be simultaneously
