Mortgage
      Bond,
      Guarantee Series D of 2005 due 2034




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 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 amended and supplemented by indentures supplemental thereto
      to which Indenture as so amended and 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 Financial
      Guaranty Insurance Company, a New York stock insurance corporation (the
“Insurer”), in connection with its issuance of a municipal bond new issue
      insurance policy (the “Policy”) in favor of the holders of the Revenue Bonds
      pursuant to the Insurance Agreement dated as of June 22, 2005 (the “Insurance
      Agreement”) between the Insurer and the Company in connection with the issuance
      of the Revenue Bonds. 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 June 1, 2005 between the Authority and
      the
      Company (the “Loan Agreement”), the Authority issued the Revenue Bonds under and
      pursuant to the Revenue Bond 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 Revenue 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 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
      interest on the Revenue 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 Revenue
      Bond Trustee pursuant to the Revenue Bond Indenture trust funds sufficient
      under
      such indenture to fully or partially pay, as the case may be, the corresponding
      amount then due of interest on the Revenue 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 interest on the bonds of this
      series only to the extent that the Insurer has made a payment with respect
      to
      the Revenue Bonds under the Policy.




The
      Trustee may
      conclusively presume that the obligation of the Company to pay the principal
      of,
      and interest, if any on the bonds of this 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
      Insurance Agreement with respect to the bonds of this series.




Upon
      payment of the
      principal of any Revenue 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 Revenue Bond 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
      such Revenue 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 or promptly following,
      the
      bonds of this series shall be surrendered to and canceled by the
      Trustee.




5


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 and continuance of
      an
      Event of Default (as defined in the Indenture) as in the Indenture
      provided.




The
      bonds of this
      series shall be redeemed by the Company in whole at any time prior to maturity
      at a redemption price of 100% of the principal amount to be redeemed, plus
      accrued and unpaid interest to the redemption date, upon receipt by the Trustee
      of written advice from the Insurer, confirmed in writing by the Revenue Bond
      Trustee, stating that the principal amount of all Revenue Bonds then outstanding
      under the Revenue Bond Indenture has been declared due and payable pursuant
      to
      the provisions of Section 11.02 of the Revenue Bond Indenture, specifying the
      date of the accelerated maturity of such Revenue Bonds and the date or dates
      from which interest on the Revenue Bonds has then accrued and is unpaid
      (specifying the rate or rates of such accrual and the principal amount of the
      particular Revenue Bonds to which such rates apply), stating such declaration
      of
      maturity has not been annulled and demanding payment of the principal amount
      of
      the bonds of this series plus accrued interest thereon to the date fixed for
      such redemption. The date fixed for such redemption shall be set forth in the
      aforesaid written advice and shall not be (i) earlier than the later of (a)
      the
      date specified in such written advice as the date of accelerated maturity of
      the
      Revenue Bonds then outstanding under the Revenue Bond Indenture, and (b), unless
      the registered owner or owners of the bonds of this series, waives the
      requirement of notice of such redemption, forty five days after the Trustee’s
      receipt of such written advice and (ii) later than fifty days after such date
      of
      accelerated maturity. Any required notice of redemption (or if the requirement
      for such notice is waived, such redemption) shall become null and void for
      all
      purposes under the Indenture upon receipt by the Trustee of written notice
      from
      the Insurer of the annulment of the acceleration of the maturity of the Revenue
      Bonds then outstanding under the Revenue Bond Indenture and of the rescission
      of
      the aforesaid written advice prior to the redemption date specified in such
      notice of redemption (or if the requirement for such notice is waived, specified
      in the aforesaid written advice), and thereupon no redemption of the bonds
      of
      this series and no payment in respect thereof as specified in such notice of
      redemption (or if the requirement for such notice is waived, as specified in
      the
      aforesaid written advice) shall be effected or required. But no such rescission
      shall extend to any subsequent written advice from the Insurer or impair any
      right consequent on such subsequent written advice.




The
      bonds of this
      series are not otherwise redeemable prior to their maturity.




Unless
      the
      requirement for such notice is waived in accordance with the preceding
      paragraph, any redemption of the bonds of this series shall be made after
      written notice to the registered owner or owners of such bonds of this series,
      sent by the Trustee by first class mail postage prepaid, at least 30 days and
      not more than 60 days before the redemption date, unless a shorter notice period
      is consented to in writing by the registered owner or owners of all bonds of
      this series and such consent is filed with the Trustee, and such redemption
      and
      notice shall be made in the manner provided in the Supplemental Indenture,
      subject to the provisions of the Indenture.




6


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 a single registered bond without coupons in a
      denomination equal to the aggregate principal amount of bonds of this series
      outstanding. If and to the extent this bond becomes transferable, the registered
      owner hereof, in person or by attorney duly authorized, may effectuate such
      transfer 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, upon surrender and
      cancellation of this bond and thereupon a new registered bond or bonds of the
      same series for a like principal amount, 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.

      contrary, the Company shall be obligated to make payments with respect to
      interest on the bonds of Guarantee Series D of 2005 only to the extent that
      the
      Insurer has made a payment with respect to the Revenue Bonds under the
      Policy.

Upon
      payment of the
      principal of any Revenue 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 Revenue Bond Indenture (other than
      by
      the application of the proceeds of any payment by the Insurer under the Policy),
      bonds of Guarantee Series D of 2005 in a principal amount equal to the principal
      amount of such Revenue 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
      Guarantee Series D of 2005 shall be surrendered to and cancelled by the Trustee.
      From and after the Release Date (as defined in the Insurance Agreement), the
      bonds of Guarantee Series D of 2005 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 Guarantee Series D of 2005 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 Guarantee Series D of 2005 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 Insurance Agreement with respect to the bonds of Guarantee
      Series D of 2005.




SECTION
      3.  Bonds
      of Guarantee
      Series D of 2005 are not transferable except in connection with the exercise
      of
      the rights and remedies of the holder thereof consequent upon an “Event of
      Default” as defined in the Indenture or as otherwise provided in the form of
      bond hereinabove set forth. If and to the extent bonds of Guarantee Series
      D of
      2005 become transferable, such transfer may be accomplished by the Holders
      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 form of bond of such series hereinabove
      recited.




SECTION
      4.  The
      principal
      amount of bonds of Guarantee Series D of 2005 which may be authenticated and
      delivered hereunder is limited to the aggregate principal amount of Forty
      Million Dollars ($40,000,000).




Bonds
      of Guarantee
      Series D of 2005 in the aggregate principal amount of Forty Million Dollars
      ($40,000,000) 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) upon the
      basis of Unbonded Class “A” Bonds issued and delivered to the Trustee for such
      purpose, 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 Sections 4.01 and 4.02 of the Indenture.

      5.  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 bonds of
      Guarantee Series D of 2005 (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
      6.  The
      consideration
      for the bonds of Guarantee Series D of 2005 shall be the issuance by the Insurer
      of the Policy pursuant to the Insurance Agreement.




SECTION
      7.  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 herein and not otherwise defined herein shall have the meaning
      ascribed to them in the Indenture.




SECTION
      8.  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
      9.  This
      Supplemental
      Indenture may be simultaneously executed in several counterparts and all such
      counterparts executed and delivered, each as an original, shall constitute
      but
      one and the same instrument.
