Article IX of the  Indenture,  reference is hereby made for a description of the
properties  mortgaged and pledged,  the nature and extent of the  security,  the
rights of the  registered  owners of the Bonds  and of the  Trustee  in  respect
thereof,  and the terms and conditions  upon which the Bonds are, and are to be,
secured.  The Bonds may be issued in series,  for various  principal  sums,  may
mature  at  different  times,  may bear  interest  at  different  rates  and may
otherwise vary as in the Indenture provided.  This First Mortgage Bond is one of
a series designated as the First Mortgage Bonds, Pollution Control Series U (the
"Pollution  Control  Series U Bonds") of the  Company,  unlimited  in  aggregate
principal amount, issued under and secured by the Indenture and described in the
supplemental  indenture  no.  1 dated  as of July 15,  1999  (the  "Supplemental
Indenture  No.  1 of July 15,  1999"),  between  the  Company  and the  Trustee,
supplemental to the Indenture.

     To  the  extent   permitted   by,  and  as  provided  in,  the   Indenture,
modifications or alterations of the Indenture,  or of any indenture supplemental
thereto,  and of the rights and obligations of the Company and of the holders of
the  Bonds  and  coupons  may be made  with the  consent  of the  Company  by an
affirmative  vote of the holders of not less than 66 2/3% in amount of the Bonds
entitled to vote then outstanding,  at a meeting of Bondholders  called and held
as provided in the Indenture,  and by an affirmative  vote of the holders of not
less than 66 2/3% in amount of the  Bonds of any  series  entitled  to vote then
outstanding and affected by such modification or alteration, in case one or more
but less than all of the series of Bonds then  outstanding  under the  Indenture
are so affected; provided however, that no such modification or alteration shall
be made which will affect the terms of payment of the  principal of, or interest
or premium, if any, on this First Mortgage Bond.

                                       92


         The  Pollution  Control  Series U Bonds are  subject to  redemption  in
accordance with the terms of Article III of the Supplemental  Indenture No. 1 of
July 15, 1999.

         In case an Event of Default, as defined in the Indenture,  shall occur,
the principal of all the Bonds at any such time outstanding  under the Indenture
may be declared or may become due and payable,  upon the  conditions  and in the
manner and with the effect  provided in the  Indenture.  The Indenture  provides
that such  declaration  may in certain  events be  rescinded by the holders of a
majority in principal amount of the Bonds outstanding.

         No  recourse  shall be had for the  payment  of the  principal  of,  or
premium or interest on this First  Mortgage  Bond, or for any claim based hereon
or  on  the  Indenture  or  any  indenture  supplemental  thereto,  against  any
incorporator,  or against any stockholder,  director or officer,  as such, past,
present  or  future,  of  the  Company,  or  of  any  predecessor  or  successor
corporation,  either directly or through the Company or any such  predecessor or
successor corporation, 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, whether at common law, in equity, by any constitution,  statute, rule
of law, or  otherwise,  of  incorporators,  stockholders,  directors or officers
being  released by every owner hereof by the  acceptance of this First  Mortgage
Bond and as part of the consideration  for the issue hereof,  and being likewise
released by the terms of the Indenture;  provided,  however, that nothing herein
or in the  Indenture  or any  indenture  supplemental  thereto  contained  shall
prevent  the  enforcement  of the  liability,  if  any,  of any  stockholder  or
subscriber  to capital  stock upon or in respect of shares of capital  stock not
fully paid up.

         Notwithstanding  any  provision  in  the  Indenture,  the  Supplemental
Indenture  No. 1 of July 15, 1999 or this First  Mortgage  Bond to the contrary,
any payment by the Company under the New Mortgage of principal of, or premium or
interest on, bonds which shall have been  authenticated  and delivered under the
New Mortgage  (the "New  Mortgage  Pollution  Control  Series U Bonds") upon the
basis of the issuance and delivery to the New Mortgage  Trustee of the Pollution
Control Series U Bonds shall,  to the extent  thereof,  be deemed to satisfy and
discharge the obligation of the Company to make a payment of principal,  premium
or interest, as the case may be, in respect of this First Mortgage Bond which is
then due.

         This First  Mortgage Bond  constitutes a "Pledged  Bond" (as defined in
the  New  Mortgage)  and  is  subject  to all of  the  rights  and  restrictions
applicable to Pledged Bonds as set forth in the New Mortgage.  Without  limiting
the  generality of the  foregoing,  this First Mortgage Bond shall be subject to
surrender by the New  Mortgage  Trustee in  accordance  with the  provisions  of
Section  7.03 of the New  Mortgage.  To the extent  that any  provisions  in the
Indenture,  the  Supplemental  Indenture of July 15, 1999 or this First Mortgage
Bond are inconsistent with the provisions relating to Pledged Bonds that are set
forth in the New Mortgage, the provisions of the New Mortgage shall apply.

         SECTION 3.  Notwithstanding  any  provision in the Original  Indenture,
this  Supplemental  Indenture No. 1, or the Pollution  Control Series U Bonds to
the contrary, any payment by the Company under the New Mortgage of principal of,
or premium or interest on, New Mortgage  Pollution Control Series U Bonds shall,

                                       93


to the extent thereof,  be deemed to satisfy and discharge the obligation of the
Company to make any payment of principal,  premium or interest,  as the case may
be, in respect of the Pollution Control Series U Bonds which is then due.

         SECTION 4. The Pollution  Control  Series U Bonds  constitute  "Pledged
Bonds" (as defined in the New Mortgage) and are subject to all of the rights and
restrictions  applicable  to  Pledged  Bonds as set  forth in the New  Mortgage.
Without limiting the generality of the foregoing, the Pollution Control Series U
Bonds shall be subject to surrender by the New  Mortgage  Trustee in  accordance
with the provisions of Section 7.03 of the New Mortgage.  To the extent that any
provisions in the Original Indenture,  this Supplemental  Indenture No. 1 or the
Pollution Control Series U Bonds are inconsistent  with the provisions  relating
to Pledged Bonds that are set forth in the New Mortgage,  the  provisions of the
New Mortgage shall apply.


                                   ARTICLE II.

                   ISSUE OF POLLUTION CONTROL SERIES U BONDS.

         SECTION  1. The  Company  hereby  exercises  the  right to  obtain  the
authentication  of $35,615,000  principal amount of additional Bonds pursuant to
the terms of Section 6 of Article III of the Original  Indenture in substitution
for refundable Bonds.
All such additional Bonds shall be Pollution Control Series U Bonds.

         SECTION 2. Such Pollution  Control Series U Bonds may be  authenticated
and delivered prior to the filing for recordation of this Supplemental Indenture
No. 1.

         SECTION 3.  Notwithstanding  any provision in the Original Indenture to
the contrary, execution of the Pollution Control Series U Bonds on behalf of the
Company,  and the attesting of the corporate seal of the Company  affixed to the
Pollution Control Series U Bonds by the officers of the Company authorized to do
such acts by Section 12 of Article II of the Original  Indenture  may be validly
done  either  by the  manual  or the  facsimile  signatures  of such  authorized
officers of the Company.


                                  ARTICLE III.

                                   REDEMPTION.

         The Pollution  Control Series U Bonds shall,  subject to the provisions
of the Original  Indenture,  be redeemable on the same terms,  on the same dates
and in the same  manner as the New  Mortgage  Pollution  Control  Series U Bonds
shall be redeemed  under the terms of  supplemental  indenture  no. 1 to the New
Mortgage dated as of July 15, 1999.

                                       94


                                   ARTICLE IV.

         The Trustee hereby accepts the trusts hereby declared and provided, and
agrees  to  perform  the same  upon the terms  and  conditions  in the  Original

         for or in respect of the validity or sufficiency  of this  Supplemental
         Indenture No. 1 or the due execution hereof by the Company or for or in
         respect of the recitals  contained  herein,  all of which  recitals are
         made by the  Company  solely.  In  general,  each  and  every  term and
         condition  contained in Article XIII of the  Original  Indenture  shall
         apply to this  Supplemental  Indenture  No. 1 with the same  force  and
         effect  as if the  same  were  herein  set  forth in  full,  with  such
         omissions,  variations and modifications  thereof as may be appropriate
         to make the same conform to this Supplemental Indenture No. 1.

                            MISCELLANEOUS PROVISIONS.

     This  Supplemental  Indenture No. 1 may be  simultaneously  executed in any
