TERMS OF SALE

The terms for each Senior Note that are not specified in the Prospectus will be
included in a Prospectus Supplement. We may sell the Senior Notes at one or more

by First Mortgage Bonds. The date that the Senior Notes are no longer secured by
First Mortgage Bonds is called the Release Date.

We urge you to carefully read this Prospectus and the Prospectus Supplement,

Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if this

DESCRIPTION OF SENIOR NOTES

GENERAL

We will issue one or more new series of Senior Notes under a Senior Note
Indenture between us and a Senior Note Trustee whom we will name. The
information we are providing you in this Prospectus concerning the Senior Note
Indenture and related documents is only a summary of the information provided in
those documents. You should consult the Senior Notes themselves, the Senior Note
Indenture, any Supplemental Senior Note Indentures and other documents for more
complete information on the Senior Notes. These documents appear as exhibits to
the Registration Statement, or will appear as exhibits to a Current Report on
Form 8-K, which we will file later, and which will be incorporated by reference
into this Prospectus.

Until the Release Date, all of the Senior Notes will be secured by one or more
series of First Mortgage Bonds, which we will issue and deliver to the Senior
Note Trustee. For more information, see "Security" and "Release Date" below.

On the Release Date, the Senior Notes

o     will cease to be secured by First Mortgage Bonds;

o     will become our unsecured obligations; and

o     will rank as equal with our other unsecured indebtedness.

The Senior Note Indenture provides that, in addition to the Senior Notes offered
under this shelf registration process, additional Senior Notes may be issued
later, without limitation as to aggregate principal amount. Before the Release
Date, however, the amount of Senior Notes that we may issue cannot exceed the
amount of First Mortgage Bonds that we are able to issue under the Mortgage. For
more information, see "Description of First Mortgage Bonds --Issuance of
Additional Bonds" below.

You should consult the Prospectus Supplement relating to any particular issue of
Senior Notes for the following information:

o     the title of the Senior Notes;

o     any limit on aggregate principal amount of the Senior Notes or the series
      of which they are a part;

o     the date on which the principal of the Senior Notes will be payable;

o     the rate, including the method of determination if applicable, at which
      the Senior Notes will bear interest, if any; and

      --    the date from which any interest will accrue;

      --    the dates on which we will pay interest; and

      --    the record date for any interest payable on any interest payment
            date;

o     the place where

      --    the principal of, premium, if any, and interest on the Senior Notes
            will be payable;

      --    you may register transfer of the Senior Notes;

      --    you may exchange the Senior Notes;


                                       4
<PAGE>

      --    you may serve notices and demands upon us regarding the Senior
            Notes;

o     the Security Registrar for the Senior Notes and whether the principal of
      the Senior Notes is payable without presentment or surrender of them;

o     the terms and conditions upon which we may elect to redeem any Senior
      Notes;

o     the terms and conditions upon which the Senior Notes must be redeemed or
      purchased due to our obligations pursuant to any sinking fund or other
      mandatory redemption provisions, or at the holder's option, including any
      applicable exceptions to notice requirements;

o     the denominations in which we may issue Senior Notes;

o     the manner in which we will determine any amounts payable on the Senior
      Notes which are to be determined with reference to an index or other fact
      or event ascertainable outside the Senior Note Indenture;

o     the currency, if other than United States currency, in which payments on
      the Senior Notes will be payable;

o     terms according to which elections can be made by us or the holder
      regarding payments on the Senior Notes in currency other than the currency
      in which the notes are stated to be payable;

o     the portion of the principal amount of the Senior Notes payable upon
      declaration of acceleration of their maturity;

o     if payments are to be made on the Senior Notes in securities or other
      property, the type and amount of the securities and other property or the
      method by which the amount shall be determined;

o     the terms applicable to any rights to convert Senior Notes into or
      exchange them for our securities or those of any other entity;

o     if we issue Senior Notes as Global Securities,

      --    any limitations on transfer or exchange rights or the right to
            obtain the registration of transfer;

      --    any limitations on the right to obtain definitive certificates for
            the Senior Notes; and

      --    any other matters incidental to the Senior Notes;

o     whether we are issuing the Senior Notes as bearer securities;

      obtain registration of their transfer, and the terms and amount of any
      service charge required for registration of transfer or exchange;

      or any variations in the definition of Business Day, with respect to the
      Senior Notes;

o     any additions to the Events of Default applicable to any Senior Notes and
      any additions to our covenants for the benefit of the holders of the
      Senior Notes;

      designation of the series of Senior Note First Mortgage Bonds to be
      delivered to the Senior Note Trustee as security for the Senior Notes;


                                       5
<PAGE>

o     any other terms of the Senior Notes not in conflict with the provisions of
      the Senior Note Indenture; and

o     any other collateral security, assurance or guarantee for the Senior
      Notes.

For more information, see Section 301 of the Senior Note Indenture.

Senior Notes may be sold at a substantial discount below their principal amount.
You should consult the applicable Prospectus Supplement for a description of
certain special United States federal income tax considerations which may apply
to Senior Notes sold at an original issue discount or denominated in a currency
other than dollars.

Unless the applicable Prospectus Supplement states otherwise, the covenants
contained in the Senior Note Indenture will not afford holders of Senior Notes
protection in the event we have a change in control or are involved after the
Release Date in a highly-leveraged transaction.

SECURITY

Until the Release Date, described in the following section, all of the Senior
Notes will be secured by one or more series of First Mortgage Bonds, which we
will issue and deliver to the Senior Note Trustee. For more information on the
First Mortgage Bonds, see "Description of First Mortgage Bonds" below. When we
issue a series of Senior Notes prior to the Release Date, we will simultaneously
issue and deliver to the Senior Note Trustee, as security for all of the Senior
Notes, a series of Senior Note First Mortgage Bonds. These First Mortgage Bonds
will have the same stated interest rate (or interest calculated in the same
manner), interest payment dates, stated maturity and redemption provisions, and
will be in the same aggregate principal amount, as the series of Senior Notes we
are issuing. For more information, see Sections 401, 402 and 403 of the Senior
Note Indenture. Payments we make to the Senior Note Trustee on a series of
Senior Notes will satisfy our obligations with respect to the corresponding
payments due on the related series of Senior Note First Mortgage Bonds.

Each series of Senior Note First Mortgage Bonds will be a series of First
Mortgage Bonds, all of which are secured by a lien on certain property we own.
For more discussion on the lien, see "Description of First Mortgage Bonds -
Priority and Security" below. In certain circumstances prior to the Release
Date, we may reduce the aggregate principal amount of Senior Note First Mortgage
Bonds held by the Senior Note Trustee. In no event, however, may we reduce that
amount to an amount lower than the aggregate outstanding principal amount of the
Senior Notes then outstanding. For more information, see Section 409 of the
Senior Note Indenture. Following the Release Date, we will close the Mortgage
and not issue any additional First Mortgage Bonds under the Mortgage. For more
information, see Section 403 of the Senior Note Indenture.

RELEASE DATE

On the Release Date, the Senior Note First Mortgage Bonds will no longer secure
the Senior Notes, and the Senior Notes will become our unsecured general
obligations. For more information, see Section 403 of the Senior Note Indenture.
The Release Date means the date that we have repaid, redeemed or otherwise
retired all of our First Mortgage Bonds, excluding Senior Note First Mortgage
Bonds securing the Senior Notes and other First Mortgage Bonds which do not in
aggregate principal amount exceed the greater of 5% of our Net


                                       6
<PAGE>

Tangible Assets or 5% of our Capitalization (each as defined in the following
section on "Limitation of Liens"). Excluding this issuance, we currently have
$224,615,000 aggregate principal amount of First Mortgage Bonds outstanding. If
an event of default under either the Senior Note Indenture or the First Mortgage
Indenture has occurred and is continuing on the date that the Release Date would
otherwise occur, the Release Date will be postponed until the event of default
has been cured.

The Senior Note Trustee will give the Senior Note holders notice when the
Release Date occurs. See "Description of Senior Notes--Defeasance" below for a
discussion of another situation in which outstanding Senior Notes would not be
secured by Senior Note First Mortgage Bonds.

LIMITATION OF LIENS

In this section and in the following section on "Limitation on Sale and
Lease-Back Transactions," the following terms have the meanings indicated:

"Capitalization" means the total of all the following items appearing on, or
included in, our consolidated balance sheet: (i) liabilities for indebtedness
maturing more than 12 months from the date of determination; and (ii) common
stock, preferred stock, premium on capital stock, capital surplus, capital in
excess of par value, and retained earnings (however the foregoing may be
designated), less, to the extent not otherwise deducted, the cost of shares of
our capital stock held in our treasury. Capitalization shall be determined in
accordance with generally accepted accounting principles and practices
applicable to the type of business in which we are engaged and approved by
independent accountants regularly retained by us, and may be determined as of a
date not more than 60 days prior to the happening of the event for which the
determination is being made.

"Debt" means any outstanding debt for money borrowed evidenced by notes,
debentures, bonds or other securities, or guarantees of any debt.

"Net Tangible Assets" means the amount shown as total assets on our consolidated
balance sheet, less (i) intangible assets including, but without limitation,
such items as goodwill, trademarks, trade names, patents, unamortized debt
discount and expense and certain regulatory assets, and (ii) appropriate
adjustments, if any, on account of minority interests. Net Tangible Assets shall
be determined in accordance with generally accepted accounting principles and
practices applicable to the type of business in which we are engaged and
approved by the independent accountants regularly retained by us, and may be
determined as of a date not more than 60 days prior to the happening of the
event for which such determination is being made.

"Operating Property" means (i) any interest in real property we own and (ii) any
asset we own that is depreciable in accordance with generally accepted
accounting principles, excluding, in either case, any interest of ours as lessee
under any lease (except for a lease that results from a Sale and Lease-Back
Transaction) which has been or would be capitalized on the books of the lessee
in accordance with generally accepted accounting principles.

"Sale and Lease-Back Transaction" means any arrangement with any person
providing for the leasing to us of any Operating Property (except for temporary
leases for a term, including any renewal or potential renewal, of not more than
48 months),


                                       7
<PAGE>

which Operating Property has been or is to be sold or transferred by us to the
person; PROVIDED, HOWEVER, Sale and Lease-Back Transaction shall not include
[any arrangement first entered into prior to the date of the Senior Note
Indenture and shall not include] any transaction pursuant to which we sell
Operating Property to, and thereafter purchase energy or services from, any
entity, which transaction is ordered or authorized by any regulatory authority
having jurisdiction over us or our operations or is entered into pursuant to any
plan or program of industry restructuring ordered or authorized by any such
regulatory authority.

"Value" means, with respect to a Sale and Lease-Back Transaction, as of any
particular time, the amount equal to the greater of (i) our net proceeds from
the sale or transfer of the property leased pursuant to the Sale and Lease-Back
Transaction or (ii) the net book value of the property, as determined by us in
accordance with generally accepted accounting principles at the time of entering
into the Sale and Lease-Back Transaction, in either case multiplied by a
fraction, the numerator of which shall be equal to the number of full years of
the term of the lease that is part of the Sale and Lease-Back Transaction
remaining at the time of determination and the denominator of which shall be
equal to the number of full years of the term, without regard, in any case, to
any renewal or extension options contained in the lease.

The Senior Note Indenture provides that, from and after the Release Date, so
long as any Senior Notes are outstanding, we may not issue, assume, guarantee
(including any contingent obligation to purchase) or permit to exist any Debt
that is secured by any mortgage, security interest, pledge or lien ("Lien") of
or upon any Operating Property owned by us, whether owned at the date of the
Senior Note Indenture or subsequently acquired, without effectively securing the
Senior Notes (together with, if we shall so determine, any other indebtedness of
ours ranking equally with the Senior Notes) equally and ratably with the Debt
(but only so long as the Debt is so secured).

The foregoing restriction will not apply to:

o     Liens on any Operating Property existing at the time of its acquisition
      and not created in contemplation of the acquisition;

o     Liens on Operating Property of a corporation existing at the time the
      corporation is merged into or consolidated with us, or at the time the
      corporation disposes of substantially all of its properties (or those of a
      division) to us provided that the Lien is not extended to property owned
      by us immediately prior to the merger, consolidation, or other disposition
      and is not created in contemplation of the merger, consolidation or other
      disposition;

o     Liens on Operating Property to secure the cost of acquisition,
      construction, development or substantial repair, alteration or improvement
      of that property or to secure indebtedness incurred to provide funds for
      any of these purposes or for reimbursement of funds previously expended
      for any of these purposes, provided the Liens are created or assumed
      contemporaneously with, or within 18 months after, the acquisition or the
      completion of substantial repair or alteration, construction, development
      or substantial improvement or within 6 months thereafter pursuant to a
      commitment for financing arranged with a lender or investor within that
      18-month period;


                                       8
<PAGE>

o     Liens in favor of the United States or any state or any department, agency
      or instrumentality or political subdivision of the United States or any
      state, or for the benefit of holders of securities issued by any of these
      entities, to secure any Debt incurred for the purpose of financing all or
      any part of the purchase price or the cost of substantially repairing or
      altering, constructing, developing or substantially improving our
      Operating Property; or

o     Any extension, renewal or replacement (or successive extensions, renewals
      or replacements), in whole or part, of any Lien referred to in the
      exceptions listed above, provided, however, that the principal amount of
      Debt secured thereby and not otherwise authorized by those exceptions
      listed above, shall not exceed the principal amount of Debt, plus any
      premium or fee payable in connection with any such extension, renewal or
      replacement, so secured at the time of such extension, renewal or
      replacement.

In addition, notwithstanding the foregoing restrictions, from and after the
Release Date we may issue, assume or guarantee Debt secured by a Lien which
would otherwise be subject to the foregoing restrictions up to an aggregate
amount which, together with all other of our secured Debt (not including secured
Debt permitted under any of the foregoing exceptions) and the Value of all Sale
and Lease-Back Transactions existing at such time (other than Sale and
Lease-Back Transactions the proceeds of which have been applied to the
retirement of certain indebtedness, Sale and Lease-Back Transactions in which
the property involved would have been permitted to be subjected to a Lien under
any of the foregoing exceptions and Sale and Lease-Back Transactions that are
permitted by the first sentence of "Limitations on Sale and Lease-Back
Transactions" below), does not exceed the greater of 10% of our Net Tangible
Assets or 10% of our Capitalization. The foregoing restrictions do not limit our
ability to place Liens on (i) the capital stock of any of our subsidiaries or
(ii) the assets of any of our subsidiaries.

LIMITATIONS ON SALE AND LEASE-BACK TRANSACTIONS

The Senior Note Indenture provides that so long as the Senior Notes are
outstanding from and after the Release Date, we may not enter into or permit to
exist any Sale and Lease-Back Transaction with respect to any Operating Property
(except for temporary leases for a term, including any renewal or potential
renewal, of not more than 48 months), if the purchaser's commitment is obtained
more than 18 months after the later of the completion of the acquisition,
construction or development of the Operating Property or the placing in
operation of the Operating Property or of the Operating Property as constructed
or developed or substantially repaired, altered or improved. This restriction
will not apply if (a) we would be entitled pursuant to any of the provisions
listed as exceptions to the restriction applicable to "Limitation on Liens"
above to issue, assume, guarantee or permit to exist Debt secured by a Lien on
the Operating Property without equally and ratably securing the Senior Notes,
(b) after giving effect to the Sale and Lease-Back Transaction, we could incur
pursuant to the provisions described in the last paragraph under "Limitation on
Liens," at least $1.00 of additional Debt secured by Liens (other than Liens
permitted by clause (a)), or (c) we apply within 180 days an amount equal to, in
the case of a sale or transfer for cash, the net proceeds (not less than the
fair value of the Operating Property so leased) and, otherwise, an amount equal
to the fair value


                                       9
<PAGE>

(as determined by our Board of Directors) of the Operating Property so leased,
to the retirement of Senior Notes or other Debt of the Company ranking equally
with the Senior Notes, subject to reduction for Senior Notes delivered and the
Debt retired during the 180-day period otherwise than pursuant to mandatory
sinking fund or prepayment provisions and payments at stated maturity.

FORM, EXCHANGE AND TRANSFER

Unless the applicable Prospectus Supplement states otherwise, we will issue
Senior Notes only in fully registered form without coupons and in denominations
of $1,000 and integral multiples of that amount. For more information, see
Sections 201 and 302 of the Senior Note Indenture.

Holders may present Senior Notes for exchange or for registration of transfer,
duly endorsed or accompanied by a duly executed instrument of transfer, at the
office of the Security Registrar or at the office of any Transfer Agent we may
designate. Exchanges and transfers are subject to the terms of the Senior Note
Indenture and applicable limitations for global securities. We may designate
ourselves the Security Registrar. No charge will be made for any registration of
transfer or exchange of Senior Notes, but we may require payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
with the transaction. Any transfer or exchange will become effective upon the
Security Registrar or Transfer Agent, as the case may be, being satisfied with
the documents of title and identity of the person making the request. For more
information, see Section 305 of the Senior Note Indenture.

The applicable Prospectus Supplement will state the name of any Transfer Agent,
in addition to the Security Registrar initially designated by the Company for
any Senior Notes. We may at any time designate additional Transfer Agents or
withdraw the designation of any Transfer Agent or make a change in the office
through which any Transfer Agent acts. We must, however, maintain a Transfer
Agent in each place of payment for the Senior Notes of each series. For more
information, see Section 702 of the Senior Note Indenture.

We will not be required to

o     issue, register the transfer of, or exchange any Senior Note or any
      Tranche of any Senior Note during a period beginning at the opening of
      business 15 days before the day of mailing of a notice of redemption of
      any Senior Note or any Tranche of any Senior Note called for redemption
      and ending at the close of business on the day of mailing; or

o     register the transfer of, or exchange any Senior Note selected for
      redemption except the unredeemed portion of any Senior Note being
      partially redeemed.

For more information, see Section 305 of the Senior Note Indenture.

PAYMENT AND PAYING AGENTS

Unless the applicable Prospectus Supplement states otherwise, we will pay
interest on a Senior Note on any interest payment date to the person in whose
name the Senior Note is registered at the close of business on the regular
record date for the interest payment. For more information, see Section 307 of
the Senior Note Indenture.

Unless the applicable Prospectus Supplement provides otherwise, we will pay
principal and any premium and interest on Senior Notes at the office of the
Paying Agent whom we will designate for this


                                       10
<PAGE>

purpose. Unless the applicable Prospectus Supplement states otherwise, the
corporate trust office of the Senior Note Trustee in New York City will be
designated as our sole Paying Agent for payments with respect to Senior Notes of
each series. Any other Paying Agents initially designated by us for the Senior
Notes of a particular series will be named in the applicable Prospectus
Supplement. We may at any time add or delete Paying Agents or change the office
through which any Paying Agent acts. We must, however, maintain a Paying Agent
in each place of payment for the Senior Notes of a particular series. For more
information, see Section 702 of the Senior Note Indenture.

All money we pay to a Paying Agent for the payment of the principal and any
premium or interest on any Senior Note which remains unclaimed at the end of two
years after payment is due will be repaid to us. After that date, the holder of
that Senior Note may look to us for these payments. For more information, see
Section 703 of the Senior Note Indenture.

REDEMPTION

You should consult the applicable Prospectus Supplement for any terms regarding
optional or mandatory redemption of Senior Notes. Except for the provisions in
the applicable Prospectus Supplement regarding Senior Notes redeemable at the
holder's option, Senior Notes may be redeemed only upon notice by mail not less
than 30 nor more than 60 days prior to the redemption date. Further, if less
than all the Senior Notes of a series, or any Tranche of a series, are to be
redeemed, the Senior Notes to be redeemed will be selected by the method
provided for the particular series. In the absence of a selection provision, the
Senior Note Trustee will select a fair and appropriate method of random
selection. For more information, see Sections 503 and 504 of the Senior Note
Indenture.

A notice of redemption we provide may state:

o     that redemption is conditioned upon receipt by the Paying Agent on or
      before the redemption date of money sufficient to pay the principal and
      any premium and interest on the Senior Notes; and

o     that if the money has not been received, the notice will be ineffective
      and we will not be required to redeem the Senior Notes.

For more information, see Section 504 of the Senior Note Indenture.

CONSOLIDATION, MERGER AND SALE OF ASSETS

We may not consolidate with or merge into any other person, nor may we transfer
or lease substantially all of our assets and property to any person, unless:

o     the corporation formed by the consolidation or into which we are merged,
      or the person which acquires by conveyance or transfer, or which leases,
      substantially all of our property and assets:

      --    is organized and validly existing under the laws of any domestic
            jurisdiction;

      --    expressly assumes our obligations on the Senior Notes and under the
            Senior Note Indenture; and

      --    prior to the Release Date, expressly assumes our obligations under
            the Senior Note First Mortgage Bonds and under the Mortgage;


                                       11
<PAGE>

o     immediately after the transaction becomes effective, no Event of Default,
      and no event which would become an Event of Default, shall have occurred
      and be continuing; and

o     we will have delivered to the Senior Note Trustee an Officer's Certificate
      and Opinion of Counsel as provided in the Senior Note Indenture.

For more information, see Section 1201 of the Senior Note Indenture.

EVENTS OF DEFAULT

"Event of Default" under the Senior Note Indenture with respect to Senior Notes
of any series means any one of the following:

o     failure to pay any interest due on the Senior Notes within 30 days;

o     failure to pay principal or premium when due on a Senior Note;

o     breach of or failure to perform any covenant or warranty of ours in the
      Senior Note Indenture with respect to the particular series of Senior
      Notes for 60 days (subject to extension under certain circumstances for
      another 120 days) after we receive notice from the Senior Note Trustee, or
      we and the Senior Note Trustee receive notice from the holders of at least
      33% in principal amount of the Senior Notes of that series outstanding
      under the Senior Note Indenture according to the provisions of the Senior
      Note Indenture;

o     prior to the Release Date, the occurrence of a Default under the Mortgage
      (see "Description of the First Mortgage Bonds - Events of Default" below);

o     certain events of bankruptcy, insolvency or reorganization; and

o     any other Event of Default set forth in the applicable Prospectus
      Supplement.

For more information, see Section 901 of the Senior Note Indenture.

An Event of Default with respect to a particular series of Senior Notes does not
necessarily constitute an Event of Default with respect to the Senior Notes of
any other series issued under the Senior Note Indenture.

If an Event of Default with respect to a particular series of Senior Notes
occurs and is continuing, either the Senior Note Trustee or the holders of at
least 33% in principal amount of the outstanding Senior Notes of that series may
declare the principal amount of all of the Senior Notes of that series to be due
and payable immediately. If the Senior Notes of that series are discount notes
or similar Senior Notes, only the portion of the principal amount as specified
in the applicable Prospectus Supplement may be immediately due and payable. If
an Event of Default occurs and is continuing with respect to all series of
Senior Notes (including all Events of Default relating to bankruptcy, insolvency
or reorganization), the Senior Note Trustee or the holders of at least 33% in
principal amount of the outstanding Senior Notes of all series, considered
together, may declare an acceleration of the principal amount of all Senior
Notes. In the event of an acceleration prior to the Release Date with respect to
all Senior Notes, the Senior Note Trustee will make a demand for acceleration of
all amounts due under all of the Senior Note First Mortgage Bonds, but this
demand will only result in such an acceleration if allowed by the acceleration
provisions of the First Mortgage.

At any time after a declaration of acceleration with respect to the Senior Notes


                                       12
<PAGE>

of a particular series, and before a judgment or decree for payment of the money
due has been obtained, and before the acceleration of the Senior Note First
Mortgage Bonds, the Event or Events of Default giving rise to the declaration of
acceleration will, without further action, be deemed to have been waived, and
the declaration and its consequences will be deemed to have been rescinded and
annulled, if

o     we have paid or deposited with the Senior Note Trustee a sum sufficient to
      pay

      --    all overdue interest on all Senior Notes of the particular series;

      --    the principal of and any premium on any Senior Notes of that series
            which have become due otherwise than by the declaration of
            acceleration and any interest at the rate prescribed in the Senior
            Notes;

      --    interest upon overdue interest at the rate prescribed in the Senior
            Notes, to the extend payment is lawful;

      --    all amounts due to the Senior Note Trustee under the Senior Note
            Indenture; and

o     any other Event of Default with respect to the Senior Notes of the
      particular series, other than the failure to pay the principal of the
      Senior Notes of that series which has become due solely by the declaration
      of acceleration, has been cured or waived as provided in the Senior Note
      Indenture.

For more information, see Section 902 of the Senior Note Indenture.

The Senior Note Indenture includes provisions as to the duties of the Senior
Note Trustee in case an Event of Default occurs and is continuing. Consistent
with these provisions, the Senior Note Trustee will be under no obligation to
exercise any of its rights or powers at the request or direction of any of the
holders, unless those holders have offered to the Senior Note Trustee reasonable
indemnity. For more information, see Section 1003 of the Senior Note Indenture.
Subject to these provisions of indemnification, the holders of a majority in
principal amount of the outstanding Senior Notes of any series may direct the
time, method and place of conducting any proceeding for any remedy available to
the Senior Note Trustee, or exercising any trust or power conferred on the
Senior Note Trustee, with respect to the Senior Notes of that series. For more
information, see Section 912 of the Senior Note Indenture.

No Senior Note holder may institute any proceeding regarding the Senior Note
Indenture, or for the appointment of a receiver or a trustee, or for any other
remedy under the Senior Note Indenture unless

o     the holder has previously given to the Senior Note Trustee written notice
      of a continuing Event of Default with respect to Senior Notes of that
      particular series,

o     the holders of a majority in aggregate principal amount of the outstanding
      Senior Notes of all series with respect to which an Event of Default is
      continuing have made a written request to the Senior Note Trustee, and
      have offered reasonable indemnity to the Senior Note Trustee to institute
      the proceeding as trustee, and

o     the Senior Note Trustee has failed to institute the proceeding, and has
      not received from the holders of a majority in principal amount of the
      outstanding Senior Notes of that series a direction inconsistent with the
      request, within 60


                                       13
<PAGE>

      days after notice, request and offer of reasonable indemnity.

For more information, see Section 907 of the Senior Note Indenture.

The preceding limitations do not apply, however, to a suit instituted by a
Senior Note holder for the enforcement of payment of the principal of or any
premium or interest on the Senior Note on or after the applicable due date
stated in the Senior Note. For more information, see Section 908 of the Senior
Note Indenture.

We must furnish annually to the Senior Note Trustee a statement by an
appropriate officer as to that officer's knowledge of our compliance with all
conditions and covenants under the Senior Note Indenture. Our compliance is to
be determined without regard to any grace period or notice requirement under the
Senior Note Indenture. For more information, see Section 706 of the Senior Note
Indenture.

MODIFICATIONS AND WAIVER

The Company and the Senior Note Trustee, without the consent of the holders of
the Senior Notes, may enter into one or more supplemental Senior Note Indentures
for any of the following purposes:

o     to evidence the assumptions by an permitted successor of our covenants in
      the Senior Note Indenture and the Senior Notes:

o     to add one or more covenants or other provisions for the benefit of the
      holders of outstanding Senior Notes or to surrender any right or power
      conferred upon us by the Senior Note Indenture;

o     to add any additional Events of Default;

o     to change or eliminate any provision of the Senior Note Indenture or add
      any new provision to it (but if this action will adversely affect the
      interests of the holders of any particular series of Senior Notes in any
      material respect, the action will become effective with respect to that
      series only when there is no Senior Note of that series remaining
      outstanding under the Senior Note Indenture);

o     to provide collateral security for the Senior Notes;

o     to establish the form or terms of Senior Notes according to the provisions
      of the Senior Note Indenture;

o     to evidence the acceptance of appointment of a successor Senior Note
      Trustee under the Senior Note Indenture with respect to one or more series
      of the Senior Notes and to add to or change any of the provisions of the
      Senior Note Indenture as necessary to provide for the administration of
      the trusts under the Senior Note Indenture by more than one trustee;

o     to provide for the procedures required to permit us to use a
      non-certificated system of registration for any Senior Notes series;

o     to change any place where

      --    the principal of and any premium and interest on any Senior Notes is
            payable,

      --    any Senior Notes may be surrendered for registration of transfer or
            exchange, or

      --    notices and demands to or upon us regarding Senior Notes and the


                                       14
<PAGE>

            Senior Note Indenture may be served; or

o     to cure any ambiguity or inconsistency (but any of these changes or
      additions will not adversely affect the interests of the holders of Senior
      Notes of any series in any material respect).

For more information see Section 1301 of the Senior Note Indenture.

The holders of at least a majority in aggregate principal amount of the
outstanding Senior Notes of any series may waive

o     compliance by us with certain provisions of the Senior Note Indenture (see
      Section 707 of the Senior Note Indenture); and

o     any past default under the Senior Note Indenture, except a default in the
      payment of principal, premium, or interest, and certain covenants and
      provisions of the Senior Note Indenture that cannot be modified or amended
      without consent of the holder of each outstanding Senior Note of the
      series affected (see Section 913 of the Senior Note Indenture).

The Trust Indenture Act of 1939 may be amended after the date of the Senior Note
Indenture to require changes to the Senior Note Indenture. In this event, the
Senior Note Indenture will be deemed to have been amended so as to effect the
changes, and we and the Senior Note Trustee may, without the consent of any
holders, enter into one or more Supplemental Senior Note Indentures to evidence
or effect the amendment. For more information, see Section 1301 of the Senior
Note Indenture.

Except as provided in this section, the consent of the holders of a majority in
aggregate principal amount of the outstanding Senior Notes, considered as one
class, is required to change in any manner the Senior Note Indenture pursuant to
one or more supplemental Senior Note Indentures. If less than all of the series
of Senior Notes outstanding are directly affected by a proposed supplemental
Senior Note Indenture, however, only the consent of the holders of a majority in
aggregate principal amount of the outstanding Senior Notes of all series
directly affected, considered as one class, will be required. Furthermore, if
the Senior Notes of any series have been issued in more than one Tranche and if
the proposed supplemental Senior Note Indenture directly affects the rights of
the holders of one or more, but not all Tranches, only the consent of the
holders of a majority in aggregate principal amount of the outstanding Senior
Notes of all Tranches directly affected, considered as one class, will be
required. In addition, an amendment or modification

o     may not, without the consent of the holder of the Senior Note

      --    change the maturity of the principal of, or any installment of
            principal of or interest on, any Senior Note,

            Mortgage Bonds to an amount less than that of the related series of

      supplemental Senior Note Indentures, waivers of certain covenants and
      waivers of past defaults with respect to the Senior Notes of any series,
      or any Tranche of a series, without the consent of the holder of each
      outstanding Senior Note affected.

A supplemental Senior Note Indenture will be deemed not to affect the rights
under the Senior Note Indenture of the holders of any series or Tranche of the
Senior Notes if the supplemental Senior Note Indenture

o     changes or eliminates any covenant or other provision of the Senior Note
      Indenture expressly included solely for the benefit of one or more other
      particular series of Senior Notes or Tranches thereof; or

o     modifies the rights of the holders of Senior Notes of any other series or
      Tranches with respect to any covenant or other provision.

For more information, see Section 1302 of the Senior Note Indenture.

If we solicit from holders of the Senior Notes any type of action, we may at our
option fix in advance a record date for the determination of the holders
entitled to vote on the action. We shall have no obligation, however, to do so.
If we fix a record date, the action may be taken before or after the record
date, but only the holders of record at the close of business on the record date
shall be deemed to be holders for the purpose of determining whether holders of
the requisite proportion of the outstanding Senior Notes have authorized the
action. For that purpose, the outstanding Senior Notes shall be computed as of
the record date. Any holder action shall bind every future holder of the same
security and the holder of every security issued upon the registration of
transfer of or in exchange for or in lieu of the security in respect of anything
done or permitted by the Senior Note Trustee or us in reliance on that action,
whether or not notation of the action is made upon the


                                       16
<PAGE>

security. For more information, see Section 104 of the Senior Note Indenture.

DEFEASANCE

Unless the applicable Prospectus Supplement provides otherwise, any Senior Note,
or portion of the principal amount of a Senior Note, will be deemed to have been
paid for purposes of the Senior Note Indenture, and, at our election, our entire
indebtedness in respect to the Senior Note (or portion thereof) will be deemed
to have been satisfied and discharged, if we have irrevocably deposited with the
Senior Note Trustee or any Paying Agent other than us, in trust, money, certain
Eligible Obligations, or a combination of the two, sufficient to pay principal
of any premium and interest due and to become due on the Senior Note or portions
thereof. For more information , see Section 801 of the Senior Note Indenture.
For this purpose, unless the applicable Prospectus Supplement provides
otherwise, "Eligible Obligations" include direct obligations of, or obligations
unconditionally guaranteed by, the United States, entitled to the benefit of
full faith and credit of the United States, and certificates, depositary
receipts or other instruments which evidence a direct ownership interest in
these obligations or in any specific interest or principal payments due in
respect to those obligations.

RESIGNATION OF SENIOR NOTE TRUSTEE

The Senior Note Trustee may resign at any time by giving written notice to us or
may be removed at any time by an action of the holders of a majority in
principal amount of outstanding Senior Notes delivered to the Senior Note
Trustee and us. No resignation or removal of the Senior Note Trustee and no
appointment of a successor trustee will become effective until a successor
trustee accepts appointment in accordance with the requirements of the Senior
Note Indenture. So long as no Event of Default or event which would become an
Event of Default has occurred and is continuing, and except with respect to a
Senior Note Trustee appointed by an action of the holders, if we have delivered
to the Senior Note Trustee a resolution of our Board of Directors appointing a
successor trustee and the successor trustee has accepted the appointment in
accordance with the terms of the Senior Note Indenture, the Senior Note Trustee
will be deemed to have resigned and the successor trustee will be deemed to have
been appointed as trustee in accordance with the Senior Note Indenture. For more
information, see Section 1010 of the Senior Note Indenture.

MISCELLANEOUS

NOTICES

GLOBAL SECURITIES

We may issue some or all of the Senior Notes of any series as Global Securities.
We will register each Global Security in the name of a depositary identified in
the applicable Prospectus Supplement. The Global Securities will be deposited
with a depositary or nominee or custodian for the depositary and will bear a
legend regarding restrictions on exchanges and registration of transfer as
discussed below and any other matters to be provided pursuant to the Senior Note
Indenture.

As long as the depositary or its nominee is the registered holder of a Global
Security, that person will be considered the sole owner and holder of the Global
Security and the Senior Notes represented by it for all purposes under the
Senior Notes and the Senior Note Indenture. Except in limited circumstances,
owners of a beneficial interest in a Global Security

o     will not be entitled to have the Global Security or any Senior Notes
      represented by it registered in their names;

o     will not receive or be entitled to receive physical delivery of
      certificated Senior Notes in exchange for the Global Security; and

o     will not be considered to be the owners or holders of the Global Security
      or any Senior Notes represented by it for any purposes under the Senior
      Notes or the Senior Note Indenture.

We will make all payments of principal and any premium and interest on a Global
Security to the depositary or its nominee as the holder of the Global Security.
The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. These laws may impair
the ability to transfer beneficial interests in a Global Security.

Ownership of beneficial interests in a Global Security will be limited to
institutions having accounts with the depositary or its nominee, called
"participants" for purposes of this discussion, and to persons that hold
beneficial interests through participants. When a Global Security is issued, the
depositary will credit on its book entry, registration and transfer system the
principal amounts of Senior Notes represented by the Global Security to the
accounts of its participants. Ownership of beneficial interests in a Global
Security will be shown only on, and the transfer of those ownership interests
will be effected only through, records maintained by

o     the depositary, with respect to participant's interests or;

o     any participant, with respect to interests of persons held by the
      participants on their behalf.

Payments by participants to owners of beneficial interests held through such
participants will be the responsibility of such participants. The depositary may
from time to time adopt various policies and procedures governing payments,
transfers, exchanges, and other matters relating to beneficial interests in a
Global Security. None of the following will have any responsibility or liability
for any aspect of the depositary or any participant's records relating to, or
for payments made on account of, beneficial interest in a Global Security, or
for maintaining, supervising or reviewing any records relating to these
beneficial interests:

o     the Southern Indiana Gas and Electric Company;


                                       18
<PAGE>

o     the Trustee under the First Mortgage Indenture;

o     the Trustee under the Senior Note Indenture; or

o     any agent of each of the above.

DESCRIPTION OF FIRST MORTGAGE BONDS

GENERAL

First Mortgage Bonds will be issued to the Senior Note Trustee to secure each
issuance of Senior Notes. See "Description of Senior Notes -- Security" above.

We will issue the First Mortgage Bonds under a Mortgage and Deed of Trust, dated
as of April 1, 1932 with Bankers Trust Company, New York, N.Y., as Trustee (the
"Trustee") pursuant to an indenture or indentures which will supplement the
Mortgage and Deed of Trust. In the following discussion, we will refer to the
Mortgage and Deed of Trust and all indentures that supplement it as the
"Mortgage".

We will refer to all of our First Mortgage Bonds, including those already issued
and those to be issued as "First Mortgage Bonds." The information we are
providing you in this Prospectus concerning the First Mortgage Bonds and the
Mortgage is only a summary of the information provided in those documents. You
should consult the Mortgage and other documents for more complete information.
These documents appear as exhibits to the Registration Statement, or will appear
as exhibits to a Current Report on Form 8-K, which we will file, and which will
be incorporated by reference into this Prospectus.

INTEREST, MATURITY, REDEMPTION AND PAYMENT

These terms will be correlated to the terms of the related Senior Notes that the
particular First Mortgage Bonds secure. See the accompanying Prospectus
Supplement.

IMPROVEMENT AND SINKING FUND REQUIREMENT

The Mortgage (Section 36A) requires the annual deposit with the Trustee of cash
equal to 1% of the maximum principal amount of all First Mortgage Bonds
outstanding at any one time subsequent to July 1, 1948 (less First Mortgage
Bonds retired directly or indirectly as a result of the sale of property or
cancelled pursuant to the provisions of Section 36B described below). We may
withdraw the cash upon certification of the amount of unfunded property
additions which would support the issuance of a principal amount of First
Mortgage Bonds equal to 100% of the amount of cash withdrawn or the cash may be
applied to the purchase or redemption of First Mortgage Bonds.

MAINTENANCE AND REPLACEMENT REQUIREMENTS

The Mortgage (Section 36B) requires the annual deposit with the Trustee of an
amount in cash or in principal amount of First Mortgage Bonds or of outstanding
prior lien bonds (or in lieu thereof the certification of unfunded property
additions) equal to the amount, if any, by which 15% of the gross earnings
during the preceding calendar year exceeds the aggregate amounts expended during
that period for repairs, maintenance and replacements. Gross earnings are
computed after deducting the costs of electric energy and gas purchased for
resale. A credit balance established in any year may be utilized to meet the
requirements during a later period


                                       19
<PAGE>

or to effect the withdrawal of deposited cash or First Mortgage Bonds or to
unfund property previously certified to the Trustee.

The Mortgage provides that, effective at such times as all First Mortgage Bonds
issued prior to January 1, 1977 are no longer outstanding, the Mortgage may be
amended to change the above requirement, insofar as it is based upon a
comparison with 15% of the gross earnings during the preceding calendar year, to
a comparison with 2.25% of our depreciable property, as defined, on December 31
of the preceding calendar year (Section 3 of the Supplemental Indenture dated as
of January 15, 1977).

PRIORITY AND SECURITY

Each First Mortgage Bond ranks pari passu as to security with all other First
Mortgage Bonds outstanding under the Mortgage, which, in the opinion of our
legal counsel, Messrs. Bamberger, Foreman, Oswald and Hahn, is a first lien on
substantially of our physical property, permits and franchises, subject only to
excepted encumbrances, as defined in the Mortgage (Section 2). The Mortgage
permits the acquisition of property subject to prior liens existing at the time
of acquisition and the use of such property additions as a basis for the
issuance of additional bonds in an amount which, together with certain other
items, does not exceed 15% of the aggregate principal amount of First Mortgage
Bonds to be outstanding under the Mortgage (Section 24).

ISSUANCE OF ADDITIONAL BONDS

The Mortgage permits the issuance of additional First Mortgage Bonds (a) to the
extent of 60% of the cost or then fair value to us, whichever is less, of
unfunded property additions (as defined in the Mortgage, Sections 4 and 5)
(Section 23); (b) to refund unfunded prior lien bonds (as defined in the
Mortgage, Section 6) (Section 24); (c) to refund First Mortgage Bonds (Section
27); or (d) upon the deposit of cash equal to the principal amount of First
Mortgage Bonds requested to be issued (Section 28). Deposited cash may be
withdrawn in lieu of the authentication of First Mortgage Bonds to which we
would otherwise be entitled or against 60% of unfunded property additions
certified to the Trustee or against the deposit of First Mortgage Bonds or the
deposit or reduction of prior lien bonds or may be applied to the purchase or
redemption of First Mortgage Bonds (Sections 29 and 30).

Additional First Mortgage Bonds may not be issued under (a) or (d) above (or
under certain circumstances under (c) above) unless net earnings (as defined in
the Mortgage, Section 7) for twelve consecutive months within the fifteen
preceding calendar months shall have been at least equal to twice the annual
interest requirements on, and at least 10% of, the principal amount of all First
Mortgage Bonds outstanding, including those proposed to be issued and all
outstanding prior lien indebtedness (Section 25). At December 31, 1998, such
coverages were at least 2.4 times and 16%, respectively. Net earnings are
computed before charges for renewals, replacements and depreciation, but after
deducting the greater of (i) 10% of gross operating revenues for such period, or
(ii) the amount by which 15% of gross operating revenues for such period exceeds
the amount expended for current repairs and maintenance. Gross operating
revenues are computed after deducting the cost of electric energy and gas
purchased for resale.

The First Mortgage Bonds issued to the Senior Note Trustee are expected to be
issued against unfunded property additions or retired bonds. Unfunded property


                                       20
<PAGE>

additions at March 31, 1999 amounted to $310,288,123.

LIMITATION ON DIVIDENDS

The Mortgage in effect restricts our payment of cash dividends on our Common
Stock to the accumulated surplus available for distribution to the Common Stock
earned subsequent to December 31, 1947, subject to reduction if amounts deducted
from earnings for current repairs and maintenance and provisions for renewals,
replacements and depreciation of all of our property are less than amounts
specified in the Mortgage (Section 1.02 of the Supplemental Indenture dated as
of July 1, 1948, as supplemented). No amount was restricted against cash
dividends on Common Stock at March 31, 1999 under this provision.

The Amended Articles of Incorporation in effect restricts our payment of cash
dividends on Common Stock to accumulated surplus available for distribution to
the Common Stock earned subsequent to December 31, 1935, and requires that,
immediately after such dividends, there shall remain to the credit of earned
surplus an amount at least equal to two times the annual dividend requirements
on all then outstanding Preferred Stock and Preferred Stock, No Par Value. See
Art. VI, Terms of Capital Stock, General Provisions (B). The amount restricted
against cash dividends on Common Stock at March 31, 1999 under this restriction
was $2,154,682, leaving $244,181,106 unrestricted for the payment of dividends.
In addition, the Amended Articles of Incorporation provides that surplus
otherwise available for the payment of dividends on Common Stock shall be
restricted to the extent that such surplus is included in a calculation required
to permit us to issue, sell or dispose of preferred stock or other stock senior
to the Common Stock. See Art. VI, Terms of Capital Stock, General Provisions
(E)(4).

An order of the Securities and Exchange Commission dated October 12, 1944 under
the Public Utility Holding Company Act of 1935 in effect restricts our payment
of cash dividends on Common Stock to 75% of net income available for
distribution to the Common Stock, earned subsequent to December 31, 1943, if the
percentage of Common Stock equity to total capitalization and surplus, as
defined, is less than 25%. At March 31, 1999, the ratio of Common Stock equity
to total capitalization and surplus amounted to approximately 53%.

MODIFICATION OF THE MORTGAGE

The Mortgage may be modified or amended by us with the consent of the holders of
all the outstanding First Mortgage Bonds issued prior to January 15, 1977 and
the consent of the holders of 66 2/3% of the principal amount of all outstanding
First Mortgage Bonds. No amendment without the consent of the holder of a First
Mortgage Bond would (1) extend the maturity of, or reduce the rate of interest
on, or otherwise modify the terms of payment of principal or interest on, or
impair the right of such holder to institute suit on or after the due date for
the enforcement of the payment of principal or interest on, that First Mortgage
Bond or (2) deprive the holder of the lien of the Mortgage or permit the
creation of any lien ranking prior to or equal with the lien of the Mortgage on
any of the mortgaged property or (3) reduce the percentage of bondholders whose
consent is required with respect to the matters specified in (1) and (2) above
(Section 4 of the Supplemental Indenture dated as of January 15, 1977).

The Mortgage permits an amendment to the Mortgage which authorizes us, effective
at such time as all First Mortgage Bonds issued


                                       21
<PAGE>

on or prior to May 31, 1986 are no longer outstanding, to designate First
Mortgage Bonds of any series (rather than the First Mortgage Bonds of the
earliest maturing series that are redeemable) as the First Mortgage Bonds to be
redeemed pursuant to Section 36B of the Mortgage and to do so at any time
(rather than only after three years) that cash for such purpose is on deposit
with the Trustee pursuant to the provisions of that Section. (Section 5 of the
Supplemental Indenture dated as of June 1, 1986). The Senior Note First Mortgage
Bonds will not be redeemable except in conjunction with the retirement of the
Senior Notes that they secure.

REGARDING DEFAULT

Under the Mortgage, the following are defined as "completed defaults":

o     failure to pay principal of any First Mortgage Bond or prior lien bond
      when due;

o     failure for 90 days to pay interest due upon any First Mortgage Bonds;

o     failure to pay interest due upon any prior lien bonds, continued for the
      period of grace, if any (not exceeding 90 days) specified in the
      instrument securing such prior lien bond;

o     the institution of voluntary proceedings involving bankruptcy or
      insolvency or appointment of a receiver for us or our property or general
      assignment for the benefit of creditors or the pendency of similar
      proceedings for 90 days if brought by others; and

o     failure for 90 days, after notice from the Trustee, to perform any other
      covenant, agreement or condition with respect to the Mortgage (Section
      66). A failure by us to deposit or direct the application of money for the
      redemption of First Mortgage Bonds called for redemption also constitutes
      a completed default (Section 52).

Upon the occurrence and continuation of a completed default, the Trustee of the
holders of not less than 20% of the First Mortgage Bonds then outstanding may
accelerate the maturity of all First Mortgage Bonds, subject to the right of the
holders of a majority of the First Mortgage Bonds to annul the acceleration if
the default has been cured and no foreclosure sale has occurred (Section 66).

REGARDING THE TRUSTEE

Bankers Trust Company, Trustee under the Mortgage, is a depositary of the
Company.

The Trustee is required to take action at the request of the holders of First
Mortgage Bonds only when requested to do so by the holders of a majority in
principal amount of the First Mortgage Bonds then outstanding. Before proceeding
to enforce the lien of the Mortgage, the Trustee may require that it be properly
indemnified to its satisfaction (Section 93).

RELEASE AND SUBSTITUTION OF PROPERTY

The Mortgage (Section 58) provides that, subject to various limitations,
property may be released from the lien thereof, whether or not sold or otherwise
disposed of by us, upon the basis of cash deposited with the Trustee, purchase
money obligations or First Mortgage Bonds delivered to the Trustee, prior lien
bonds delivered to the Trustee or reduced or assumed, or unfunded property
additions certified to the Trustee.

The Mortgage (Section 60) permits the cash proceeds of released property to be
withdrawn against unfunded property


                                       22
<PAGE>

additions certified to the Trustee or against the deposit of First Mortgage
Bonds or the deposit or reduction of prior lien bonds or to be applied to the
purchase or redemption of First Mortgage Bonds.

EVIDENCE TO BE FURNISHED TO THE TRUSTEE UNDER THE MORTGAGE

Compliance with Mortgage provisions is evidenced by written statements of our
officers or persons selected or paid by us (such as an engineer with respect to
the value of property being certified or released, an accountant with respect to
a net earnings certificate and counsel with respect property titles and
compliance with the Mortgage generally). In certain major matters (as required
by Section 314(d) of the Trust Indenture Act of 1939, as amended) the accountant
or engineer must be independent. We are required to file a treasurer's
certificate with the Trustee on or before May 1 of each year indicating that we
have complied with all the provisions of the Mortgage and are not in default
with respect to any of the covenants contained in the Mortgage (Section 3.06 of
the Supplemental Indenture dated as of July 1, 1948). Various other certificates
and papers are required to be filed annually and upon the happening of various
events.

PLAN OF DISTRIBUTION

We intend to sell the Senior Notes in a public offering through the underwriters
or dealers named on the cover of the applicable Prospectus Supplement.

The applicable Prospectus Supplement will set forth the terms under which the
Senior Notes are offered, including

o     the purchase price and the net proceeds to us from the sale;

o     any underwriting discounts and other items constituting underwriters
      compensation;

o     the initial public offering price; and

o     any discounts or concessions allowed, re-allowed or paid to dealers.

We or any underwriters or dealers may change from time to time any initial
public offering price and any discounts or concessions allowed or re-allowed or
paid to dealers.

The Senior Notes will be acquired by the underwriters for their own account and
may be resold in one or more transactions, including negotiated transactions, at
a fixed public offering price or at varying prices determined at the time of the
sale. Unless the applicable Prospectus Supplement states otherwise, the
obligations of any underwriter to purchase the Senior Notes will be subject to
certain conditions, and the underwriter will be obligated to purchase the Senior
Notes, except that in certain cases involving a default by an underwriter, less
than all of the Senior Notes may be purchased.

The applicable Prospectus Supplement will state whether we will authorize
underwriters or dealers to solicit offers by certain specified institutions to
purchase Senior Notes at the public offering price set forth in the Prospectus
Supplement pursuant to delayed delivery contracts providing for payment and
delivery on a specified future date. These contracts will be subject to the
conditions set forth in the Prospectus Supplement. Additionally, the Prospectus
Supplement will set forth the commission payable for solicitation of those
contracts.

The underwriters may be entitled under agreements entered into with the Company
to indemnification by the Company against


                                       23

certain civil liabilities, including liabilities under the Securities Act of
1933.

Item 15. Indemnification of Directors and Officers.

The following resolution was adopted by the Executive Committee of the Board of
Directors of the Company on May 12, 1999:


            RESOLVED: that with respect to the preparation and filing of a
            Registration Statement and Prospectus with the Securities and
            Exchange Commission in connection with the proposed issuance and
            sale from time to time of Securities of the Company at an aggregate
            initial offering price not to exceed $90,000,000, this Company
            indemnify and save harmless each and every officer of the Company
            executing and preparing the Registration Statement and Prospectus in
            its original or amended or supplemented form, and every director of
            the Company who was a director thereof at the time of the filing of
            the Registration Statement and Prospectus in their original or
            amended or supplemented form, against any and all costs reasonably
            incurred by them or any of them in connection with any action, suit
            or proceeding arising out of the preparation, filing or use of the
            said Registration Statement or Prospectus relating to such issue
            whether brought under the Securities Act of 1933, as amended, or
            under any other applicable law, where such action, suit or
            proceeding is finally adjudicated in favor of such director, officer
            or employee and the time to appeal has expired.

Similar indemnity resolutions have been adopted which are applicable to other
issues of securities presently outstanding, and similar general indemnity

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

            (1) To file, during any period in which offers or sales are being
      made, a post-effective amendment to this Registration Statement (i) to
      include any prospectus required by Section 10(a)(3) of the Securities Act
      of 1933; (ii) to reflect in the Prospectus any facts or events arising
      after the effective date of the Registration Statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in the
      Registration Statement (notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than 20 percent change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective Registration Statement); or (iii) to include any material
      information with respect to the plan of distribution not previously
      disclosed in the Registration Statement or any material change to such
      information in the Registration Statement; provided, however, that the
      registrant need not file a post-effective amendment to include the
      information required to be included by subsection (i) or (ii) if such
      information is contained in periodic reports filed with or furnished to
      the Commission by the registrant pursuant to Section 13 or Section 15(d)
      of the Securities Exchange Act of 1934 that are incorporated by reference
      in the Registration Statement.

            (2) That, for the purpose of determining any liability under the
      Securities Act of 1933, each such post-effective amendment shall be deemed
      to be a new registration


                                      II-3
<PAGE>

      statement relating to the securities offered therein, and the offering of
      such securities at that time shall be deemed to be the initial bona fide
      offering thereof.

            (3) To remove from registration by means of a post-effective
      amendment any of the securities being registered that remain unsold at the
      termination of the offering.

            (4) That, for purposes of determining any liability under the
      Securities Act of 1933, each filing of the registrant's annual report
      pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
      of 1934 (and, where applicable, each filing of an employee benefit plan's
      annual report pursuant to Section 15(d) of the Securities Exchange Act of
      1934) that is incorporated by reference in this Registration Statement
      shall be deemed to be a new registration statement relating to the
      securities offered herein, and the offering of such securities at that
      time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                            Southern Indiana Gas and
                                Electric Company

                             Underwriting Agreement

To the Representatives of the
   several Underwriters named in
   the respective Pricing Agreements
   hereinafter described.

                                                ________ __, 1999

Dear Sirs:

            From time to time Southern Indiana Gas and Electric Company, an
Indiana corporation (the "Company"), proposes to enter into one or more Pricing
Agreements (each a "Pricing Agreement") in the form of Annex I hereto, with such
additions and deletions as the parties thereto may determine, and, subject to
the terms and conditions stated herein and therein, to issue and sell to the
firms named in Schedule I to the applicable Pricing Agreement (such firms
constituting the "Underwriters" with respect to such Pricing Agreement and the
Senior Notes specified therein) certain of its Senior Notes (the "Senior
Notes"). Senior Notes specified in Schedule II to a Pricing Agreement are
hereinafter referred to as the "Designated Senior Notes" with respect to such
Pricing Agreement.

            The Senior Notes are to be issued under a governing indenture
(together with any supplements, the "Senior Note Indenture") each between the
Company and ___________________, as Trustee (the "Senior Note Trustee"), in
substantially the form heretofore delivered to the Representatives. Until the
Release Date (as defined in the Senior Note Indenture), the Senior Notes will be
secured by one or more series of Senior Note First Mortgage Bonds (as defined in
the Senior Note Indenture) issued and delivered by the Company to the Senior
Note Trustee. On the Release Date, the Senior Notes will cease to be secured by
the Senior Note First Mortgage Bonds and will become unsecured obligations of
the Company. The Senior Note First Mortgage Bonds securing the Senior Notes will
be issued under the Company's Mortgage and Deed of Trust, dated as of April 1,
1932, with Bankers Trust Company, New York, New York, as Trustee (the "Mortgage
Trustee"), as heretofore supplemented and amended by

<PAGE>
                                                                               2


Supplemental Indentures and as the same may be further supplemented by a
Supplemental Indenture relating to the Senior Note First Mortgage Bonds (such
Mortgage and Deed of Trust, as so supplemented and amended and as to be
supplemented and amended being hereinafter referred to as the "Mortgage" and
such Supplemental Indenture being referred to as the "Supplemental Indenture").
The terms and rights of the Senior Notes shall be as specified in the Pricing
Agreement relating thereto and specified in or pursuant to the Senior Note
Indenture.

            1. Particular sales of Designated Senior Notes may be made from time
to time to the Underwriters of such Senior Notes for whom the firms designated
as representatives of the Underwriters of such Senior Notes in the Pricing
Agreement relating thereto will act as representatives (the "Representatives").
The term "Representatives" also refers to a single firm acting as sole
representative of the Underwriters and to Underwriters who act without any firm
being designated as their representative. This Agreement shall not be construed
as an obligation of the Company to sell any of the Senior Notes to the
Underwriters or as an obligation of any of the Underwriters to purchase any of
the Senior Notes. The obligation of the Company to issue and sell any of the
Senior Notes and the obligation of any of the Underwriters to purchase any of
the Senior Notes shall be evidenced by the Pricing Agreement with respect to the
Designated Senior Notes specified therein. Each Pricing Agreement shall specify
the aggregate principal amount of such Designated Senior Notes, the public
offering price of such Designated Senior Notes, the purchase price to the
Underwriters of such Designated Senior Notes, the names of the Underwriters of
such Designated Senior Notes, the names of the Representatives of such
Underwriters and the principal amount of such Designated Senior Notes to be
purchased by each Underwriter, and shall set forth the date, time and manner of
delivery of such Designated Senior Notes and payment therefor. The Pricing
Agreement shall also specify (to the extent not set forth in the Senior Note
Indenture, the Registration Statement (as defined in Section 2 hereof) and the
Prospectus (as defined in Section 2 hereof)) the terms of such Designated Senior
Notes. A Pricing Agreement shall be in the form of an executed writing (which
may be in counterparts), and may be evidenced by an exchange of telegraphic
communications or communications transmitted through any other rapid
transmission device designed to produce a written record of communications
transmitted. The obligations of the Underwriters under this Agreement and each
Pricing Agreement shall be several and not joint.

            2. The Company represents and warrants to, and agrees with, each of
the Underwriters that:

            (a) A registration statement in respect of the Senior Notes has been
      filed with the Securities and Exchange Commission (the "Commission"); such
      registration statement

<PAGE>
                                                                               3


      and any post-effective amendment thereto, each in the form heretofore
      delivered or to be delivered to the Representatives and, excluding
      exhibits to such registration statement, but including all documents
      incorporated by reference in the prospectus contained therein, to the
      Representatives for each of the other Underwriters have been declared
      effective by the Commission in such form; other than a registration
      statement, if any, increasing the size of the offering (a "Rule 462(b)
      Registration Statement"), filed, pursuant to rule 462(b) under the
      Securities Act of 1933, as amended (the "Act"), which became effective
      upon filing, no other document with respect to such registration statement
      or document incorporated by reference therein has heretofore been filed or
      transmitted for filing with the Commission; and no stop order suspending
      the effectiveness of such registration statement or the Rule 462(b)
      Registration Statement, if any, has been issued and no proceeding for that
      purpose has been initiated or threatened by the Commission (any
      preliminary prospectus included in such registration statement or filed
      with the Commission pursuant to Rule 424(a) of the rules and regulations
      of the Commission under the Act being hereinafter called a "Preliminary
      Prospectus"; the various parts of such registration statement and the Rule
      462(b) Registration Statement, if any, including all exhibits thereto and
      the documents incorporated by reference in the prospectus contained in the
      registration statement at the time such part of the registration statement
      became effective but excluding Form T-1, each as amended at the time such
      part of the Registration Statement became effective or such part of the
      Rule 462(b) Registration Statement, if any, became effective, being
      hereinafter called the "Registration Statement"; the prospectus relating
      to the Senior Notes, in the form in which it has most recently been filed,
      or transmitted for filing, with the Commission on or prior to the date of
      this Agreement, being hereinafter called the "Prospectus"; any reference
      herein to any Preliminary Prospectus or the Prospectus shall be deemed to
      refer to and include the documents incorporated by reference therein
      pursuant to the applicable form under the Act, as of the date of such
      Preliminary Prospectus or Prospectus, as the case may be; any reference to
      any amendment or supplement to any Preliminary Prospectus or the
      Prospectus shall be deemed to refer to and include any documents filed
      after the date of such Preliminary Prospectus or Prospectus, as the case
      may be, under the Securities Exchange Act of 1934, as amended (the
      "Exchange Act"), and incorporated by reference in such Preliminary
      Prospectus or Prospectus, as the case may be; any reference to any
      amendment to the Registration Statement shall be deemed to refer to and
      include any annual report of the Company filed pursuant to Section 13(a)
      or 15(d) of the Exchange Act after the effective date of the Registration
      Statement that is incorporated by reference in

<PAGE>
                                                                               4


      the Registration Statement; and any reference to the Prospectus as amended
      or supplemented shall be deemed to refer to the Prospectus as amended or
      supplemented in relation to the applicable Designated Senior Notes in the
      form in which it is filed with the Commission pursuant to Rule 424(b)
      under the Act in accordance with Section 5(a) hereof, including any
      documents incorporated by reference therein as of the date of such
      filing);

            (b) The documents incorporated by reference in the Prospectus, when
      they became effective or were filed with the Commission, as the case may
      be, conformed in all material respects to the requirements of the Act or
      the Exchange Act, as applicable, and the rules and regulations of the
      Commission thereunder, and none of such documents contained an untrue
      statement of a material fact or omitted to state a material fact required
      to be stated therein or necessary to make the statements therein not
      misleading; and any further documents so filed and incorporated by
      reference in the Prospectus or any further amendment or supplement
      thereto, when such documents become effective or are filed with the
      Commission, as the case may be, will conform in all material respects to
      the requirements of the Act or the Exchange Act, as applicable, and the
      rules and regulations of the Commission thereunder and will not contain an
      untrue statement of a material fact or omit to state a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading; provided, however, that this representation and warranty
      shall not apply to any statements or omissions made in reliance upon and
      in conformity with information furnished in writing to the Company by an
      Underwriter of Designated Senior Notes through the Representatives
      expressly for use in the Prospectus as amended or supplemented relating to
      such Senior Notes;

            (c) The Registration Statement and the Prospectus conform, and any
      further amendments or supplements to the Registration Statement or the
      Prospectus will conform, in all material respects to the requirements of
      the Act and the Trust Indenture Act of 1939 (the "Trust Indenture Act")
      and the rules and regulations of the Commission thereunder and do not and
      will not, as of the applicable effective date as to the Registration
      Statement and as of the applicable filing date as to the Prospectus and
      any amendment or supplement thereto, contain an untrue statement of a
      material fact or omit to state a material fact required to be stated
      therein or necessary to make the statements therein not misleading;
      provided, however, that this representation and warranty shall not apply
      to any statements or omissions made in reliance upon and in conformity
      with information furnished in writing to the Company by an Underwriter of
      Designated Senior Notes through

<PAGE>
                                                                               5


      the Representatives expressly for use in the Prospectus as amended or
      supplemented relating to such Senior Notes;

            (d) Other than as set forth in or contemplated by the Prospectus,
      (i) the Company has not sustained since the date of the latest audited
      financial statements included or incorporated by reference in the
      Prospectus any material loss or interference with its business whether or
      not insured against; and (ii) since the respective dates as of which
      information is given in the Registration Statement and the Prospectus,

      be affected by the Year 2000 Problem and has completed or is in the
      process of completing measures which are designed to address the Year 2000
      Problem. As a result of such review and such measures, the Company has no
      reason to believe, and does not believe, that the Year 2000 Problem will
      have a material adverse effect on the general affairs, management, the
      current or future consolidated financial position, business prospects,
      stockholders' equity or results of operations of the Company and its
      subsidiaries or result in any material loss or interference with the
      Company's business or operations. The "Year 2000 Problem" as used herein
      means any significant risk that computer hardware or software used in the
      receipt, transmission, processing, manipulation, storage, retrieval,
      retransmission or other utilization of data or in the operation of
      mechanical or electrical systems of any kind will not, in the case of

      as effectively as in the case of dates or time periods occurring prior to
      January 1, 2000.

      United States of a national emergency or war if the effect of any such
      event specified in this Clause (iii) in the judgment of the
      Representatives makes it impracticable or inadvisable to proceed with the
      public offering or the delivery of the Designated Senior Notes on

                                                                              22


      the terms and in the manner contemplated in the Prospectus as amended or
      supplemented;

            (i) The Company shall have complied with the provisions of Section
      5(c) hereof with respect to the furnishing of prospectuses on the New York
      Business Day next succeeding the date of this Agreement; and

            (j) The Company shall have furnished or caused to be furnished to
      the Representatives at the Time of Delivery for the Designated Senior
      Notes a certificate or certificates of officers of the Company
      satisfactory to the Representatives as to the accuracy of the
      representations and warranties of the Company herein at and as of such
      Time of Delivery, as to the performance by the Company of all of its
      obligations hereunder to be performed at or prior to such Time of
      Delivery, as to the matters set forth in subsections (a) and (f) of this
      Section and as to such other matters as the Representatives may reasonably
      request.

      8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Senior Notes, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, any preliminary prospectus supplement, the Registration Statement,
the Prospectus as amended or supplemented and any other prospectus relating to
the Senior Notes, or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
of Designated Senior Notes through the Representatives expressly for use in the
Prospectus as amended or supplemented relating to such Senior Notes; and
provided further, that the Company shall not be liable to any Underwriter under
the indemnity agreement in this subsection (a) with respect to any Preliminary
Prospectus to the extent that any such loss, claim, damage or liability of such
Underwriter results from the fact

<PAGE>
                                                                              23


that such Underwriter sold Designated Senior Notes to a person as to whom it
shall be established that there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the Prospectus in any case where
such delivery is required by the Act if such Underwriter failed to make
reasonable efforts generally consistent with the then prevailing industry
practice and the Company has previously furnished copies thereof in sufficient
quantity and on a timely basis to such Underwriter and the loss, claim, damage
or liability of such Underwriter results from an untrue statement or omission of
a material fact contained in the Preliminary Prospectus which was identified in
writing to such Underwriter and corrected in the Prospectus.

            (b) Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented and any
other prospectus relating to the Senior Notes, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Senior Notes, or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives expressly for use therein; and will reimburse the Company for
any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.

            (c) Promptly after receipt by an indemnified party under Subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel

<PAGE>
                                                                              24


satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying party), and, after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party under such subsection for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.

            (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
Subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and the Underwriters of the
Designated Senior Notes on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations, including relative benefit. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or such Underwriters on the other, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Subsection (d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Subsection (d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in this
Subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this Subsection (d),
no Underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the applicable Designated Senior Notes
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be

<PAGE>
                                                                              25


entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Underwriters of Designated Senior
Notes in this Subsection (d) to contribute are several in proportion to their
respective underwriting obligations with respect to such Senior Notes and not
joint.

            (e) The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company and to each
person, if any, who controls the Company within the meaning of the Act.

            9. (a) If any Underwriter shall default in its obligation to
purchase the Designated Senior Notes which it has agreed to purchase under the
Pricing Agreement relating to such Designated Senior Notes, the Representatives
may in their discretion arrange for themselves or another party or other parties
to purchase such Designated Senior Notes on the terms contained herein. If
within thirty-six hours after such default by any Underwriter the
Representatives do not arrange for the purchase of such Designated Senior Notes,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to the
Representatives to purchase such Designated Senior Notes on such terms. In the
event that, within the respective prescribed period, the Representatives notify
the Company that they have so arranged for the purchase of such Designated
Senior Notes, or the Company notifies the Representatives that it has so
arranged for the purchase of such Designated Senior Notes, the Representatives
or the Company shall have the right to postpone the Time of Delivery for such
Designated Senior Notes for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus as amended or supplemented, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments or supplements to the Registration Statement or the Prospectus which
in the opinion of the Representatives may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section 9 with like effect as if such person had originally been a
party to the Pricing Agreement relating to such Designated Senior Notes.

            (b) If, after giving effect to any arrangements for the purchase of
the Designated Senior Notes of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in Subsection (a) above, the
aggregate

<PAGE>
                                                                              26


principal amount of such Designated Senior Notes which remains unpurchased does
not exceed one-eleventh of the aggregate principal amount of the Designated
Senior Notes, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the principal amount of Designated Senior
Notes which such Underwriter agreed to purchase under the Pricing Agreement
relating to such Designated Senior Notes and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the
principal amount of Designated Senior Notes which such Underwriter agreed to
purchase under such Pricing Agreement) of the Designated Senior Notes of such
defaulting Underwriter or Underwriters for which such arrangements have not been
made; but nothing herein shall relieve a defaulting Underwriter from liability
for its default.

            (c) If, after giving effect to any arrangements for the purchase of
the Designated Senior Notes of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in Subsection (a) above, the
aggregate principal amount of Designated Senior Notes which remains unpurchased
exceeds one-eleventh of the aggregate principal amount of the Designated Senior
Notes, as referred to in Subsection (b) above, or if the Company shall not
exercise the right described in Subsection (b) above to require non-defaulting
Underwriters to purchase Designated Senior Notes of a defaulting Underwriter or
Underwriters, then the Pricing Agreement relating to such Designated Senior
Notes shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

            10. The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of and payment for the Senior Notes.

            11. If any Pricing Agreement shall be terminated pursuant to Section
9 hereof, the Company shall not then be under any liability to any Underwriter
with respect to the Designated Senior Notes covered by such Pricing Agreement
except as provided in Section 6 and Section 8 hereof; but, if for any other
reason Designated Senior Notes are not delivered by or on behalf of the Company
as provided herein, the Company will reimburse the Underwriters through the
Representatives for all out-of-pocket

<PAGE>
                                                                              27


expenses approved in writing by the Representatives, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of such Designated Senior
Notes, but the Company shall then be under no further liability to any
Underwriter with respect to such Designated Senior Notes except as provided in
Section 6 and Section 8 hereof.

            12. In all dealings hereunder, the Representatives of the
Underwriters of Designated Senior Notes shall act on behalf of each of such
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by such Representatives jointly or by such of the Representatives, if any,
as may be designated for such purpose in the Pricing Agreement.

            All statements, requests, notices and agreements hereunder shall be
in writing, and if to the Underwriters shall be delivered or sent by mail or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail or
facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
registered mail to such Underwriter at its address provided to the Company for
the purpose of notices pursuant to such Section 8(c).

            13. This Agreement and each Pricing Agreement shall be binding upon,
and inure solely to the benefit of, the Underwriters, the Company and, to the
extent provided in Section 8 and Section 10 hereof, the officers and directors
of the Company and each person who controls the Company or any Underwriter, and
their respective heirs, executors, administrators, successors and assigns, and
no other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement. No purchaser of any of the Senior Notes
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

            14. Time shall be of the essence of each Pricing Agreement. As used
herein, "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business. As used herein, "New York Business Day"
shall mean any day when the New York Stock Exchange is open for business.

            15. THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

            16. This Agreement and each Pricing Agreement may be executed by any
one or more of the parties hereto and thereto in

all such respective counterparts shall together constitute one and the same

made at and as of the date of this Pricing Agreement, except that each of the

the Prospectus as amended or supplemented relating to the Designated Senior
Notes which are the subject of this Pricing Agreement. Each reference to the

                                          ---------------------------------


Accepted as of the date hereof:

            Pursuant to Section 7(d) of the Underwriting Agreement, the
accountants shall furnish a letter to the Underwriters to the effect that:

                  (i) They are independent certified public accountants with
      respect to the Company and its subsidiaries within the meaning of the Act
      and the applicable published rules and regulations thereunder;

                  (ii) In their opinion, the financial statements and any
      supplementary financial information and schedules (and, if applicable,
      prospective financial statements and/or pro forma financial information)
      examined by them and included or incorporated by reference in the
      Registration Statement or the Prospectus comply as to form in all material
      respects with the applicable accounting requirements of the Act or the
      Exchange Act, as applicable, and the related published rules and
      regulations thereunder; and, if applicable, they have made a review in
      accordance with standards established by the American Institute of
      Certified Public Accountants of the consolidated interim financial
      statements, selected financial data, pro forma financial information,
      prospective financial statements and/or condensed financial statements
      derived from audited financial statements of the Company for the periods
      specified in such letter, as indicated in their reports thereon, copies of
      which have been furnished to the representative of the Underwriters (the
      "Representatives");

                  (iii) The unaudited selected financial information with
      respect to the consolidated results of operations and financial position
      of the company for the five most recent fiscal years included in the
      Prospectus and included or incorporated by reference in Item 6 of the
      Company's Annual Report on Form 10-K for the most recent fiscal year
      agrees with the corresponding amounts (after restatement where applicable)
      in the audited consolidated financial statements for five such fiscal
      years which were included or incorporated by reference in the Company's
      Annual Reports on Form 10-K for such fiscal years;

                  (iv) On the basis of limited procedures, not constituting an
      examination in accordance with generally accepted auditing standards,
      consisting of a reading of the unaudited financial statements and other
      information referred to below, a reading of the latest available interim
      financial statements of the Company and its subsidiaries, inspection of
      the minute books of the Company and its subsidiaries since the date of the
      latest audited financial statements included or incorporated by reference
      in the Prospectus, inquiries of officials of the Company and its
      subsidiaries responsible for financial and accounting

      matters and such other inquiries and procedures as may be specified in
      such letter, nothing came to their attention that caused them to believe
      that:

                  (A) the unaudited condensed consolidated statements of income,
            consolidated balance sheets and consolidated statements of cash
            flows included or incorporated by reference in the Company's
            Quarterly Reports on Form 10-Q incorporated by reference in the
            Prospectus do not comply as to form in all material respects with
            the applicable accounting requirements of the Exchange Act as it
            applies to Form 10-Q and the related published rules and regulations
            thereunder or are not in conformity with generally accepted
            accounting principles applied on a basis substantially consistent
            with the basis for the audited consolidated statements of income,
            consolidated balance sheets and consolidated statements of cash
            flows included or incorporated by reference in the Company's Annual
            Report on Form 10-K for the most recent fiscal year;

                  (B) any other unaudited income statement data and balance
            sheet items included in the Prospectus do not agree with the
            corresponding items in the unaudited consolidated financial
            statements from which such data and items were derived, and any such
            unaudited data and items were not determined on a basis
            substantially consistent with the basis for the corresponding
            amounts in the audited consolidated financial statements included or
            incorporated by reference in the Company's Annual Report on Form
            10-K for the most recent fiscal year;

                  (C) the unaudited financial statements which were not included
            in the Prospectus but from which were derived the unaudited
            condensed financial statements referred to in clause (A) and any
            unaudited income statement data and balance sheet items included in
            the Prospectus and referred to in Clause (B) were not determined on
            a basis substantially consistent with the basis for the audited
            financial statements included or incorporated by reference in the

                    SOUTHERN INDIANA GAS AND ELECTRIC COMPANY

          FIRST MORTGAGE BOND, __% SENIOR NOTE SERIES OF 1999 DUE 20__

            This bond is one of an issue of First Mortgage Bonds of the Company,
issuable in series, and is one of the series designated in the title hereof, all
issued and to be issued under and equally secured (except as to any sinking fund
established in accordance with the provisions of the Mortgage hereinafter
mentioned for the bonds of any particular series) by an Indenture of Mortgage
and Deed of Trust, dated as of April 1, 1932, executed by the Company to Bankers

supplemental thereto, to which Indenture as so amended and supplemented (herein
referred to as the Mortgage) 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 principal hereof may be declared or may become due on the
conditions, with the effect, in the manner and at the time set forth in the
Mortgage, upon the occurrence of a completed default as provided in the
Mortgage.

            The bonds of this series shall be redeemable as follows: [     ]

            This bond is transferable as prescribed in the Mortgage by the
registered owner hereof in person, or by his duly authorized attorney, at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, New York, upon surrender and cancellation of this bond, and thereupon, a
new fully registered bond of the same series for a like principal amount will be
issued to the transferee in exchange thereof as provided in the Mortgage, and
upon payment, if the Company shall require it, of the 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, premium, if any, and interest due
hereon and for all other purposes.

            The bonds of this series are issuable as registered bonds without
coupons in denominations of $1,000 and authorized multiples thereof. In the
manner and upon payment of the charges prescribed in the Mortgage, registered
bonds without coupons of this series may be exchanged for a like aggregate
principal amount of registered bonds without coupons of other authorized
denominations of the same series, upon presentation and surrender thereof, for
cancellation, to the Trustee at its principal corporate trust office in the
Borough of Manhattan, The City of New York, New York.

            No recourse shall be had for the payment of the principal of,
premium, if any, or interest on this bond against any incorporator or any past,
present or future subscriber to the capital stock, stockholder, office or
director of the Company or of any predecessor or successor corporation, either
directly or through the Company or any predecessor or successor corporation,
under any rule of law, statute or constitution or by the enforcement of any
assessment or otherwise, all such liability of incorporators, subscribers,
stockholders, officers and directors being released by the holder or owner
hereof by the acceptance of this bond and being likewise waived and released by
the terms of the Mortgage.

            Pursuant to the Mortgage, the holder or owner of this bond by his
acceptance hereof is deemed to have agreed to amendments to the Mortgage which
will eventually permit certain amendments to the Mortgage with the consent of
the holders of 66% of the principal amount of the outstanding bonds of all
series issued under the Mortgage, which redefine, effective at such time as all
bonds of each series of bonds issued under the Mortgage prior to January 1, 1977
are no longer outstanding, the amounts required to be spent by the Company under
the Mortgage for the repair, maintenance, renewal and replacement of its
property and which authorize the Company, effective at such time as all bonds of
each series issued under the Mortgage on or prior to May 31, 1986 are no longer
outstanding, to designate bonds of any series as the bonds to be redeemed
pursuant to Section 36B of the Mortgage and to do so at any time that cash for
such purpose is on deposit with Trustee pursuant to the provisions of that
Section.

or taxes or other governmental charge required to be paid by the Company. The
form of the temporary bonds of said series shall be in substantially the form of
the form of registered bond hereinbefore recited with such appropriate changes
therein as are required on account of the temporary nature thereof. Said
temporary bonds of said series shall be in registered form without coupons and
shall be exchangeable for definitive bonds of said series when prepared.

            The person in whose name any registered bond without coupons of the
Thirty-Eighth Series is registered at the close of business on any record date
(as hereinbelow defined) with respect to any interest payment date 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 is
registered either at the close of business on the day preceding the date of
payment of such defaulted interest or on a subsequent record date for such
payment if one shall have been established as hereinafter provided. A subsequent
record date may be established by or on behalf of the Company by notice mailed
to the holders of bonds not less than ten days preceding such record date, which
record date shall be not more than thirty days prior to the subsequent interest
payment date. The term "record date" as used in this Section with respect to any
regular interest payment date shall mean the ________ 15 or ________ 15, as the
case may be, next preceding such interest payment date, or, if such ________ 15
or ________ 15 shall be a legal holiday or a day on which banking institutions
in the Borough of Manhattan, The City of New York, New York, are authorized or
obligated by law to close, the next preceding day which shall not be a legal
holiday or day on which such institutions are so authorized or obligated to
close.

            Except as provided in this Section, every registered bond without
coupons of the Thirty-Eighth Series shall be dated and shall bear interest as
provided in Section 10 of the Indenture; provided, however, that so long as
there is no existing default in the payment of interest on the bonds, the holder
of any bond authenticated by the Trustee between the record date for any
interest payment date and such interest payment date shall not be entitled to
the payment of the interest due on such interest payment date and shall have no
claim against the Company with respect thereto; and provided, further, that, if
and to the extent the Company shall default in the payment of the interest due
on such interest payment date, then any such bond shall bear interest from the
________ 1 or ________ 1, as the case may be, next preceding the date of such
bond, to which interest has been paid or, if the Company shall be in default
with respect to the interest due on ________ 1, 1999, then from ________ 1,
1999.

            Bonds of the Thirty-Eighth Series shall be redeemable as follows:

            SECTION 2. The Company's obligation to make payments with respect to
the principal of, premium, if any, and/or interest on, the bonds of the
Thirty-Eighth 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 premium, if any, and/or interest then due on,
the senior notes (the "Senior Notes") issued pursuant to the Indenture (for
Senior Notes) dated as of July __, 1999, between the Company and Bankers Trust
Company, the Senior Note Trustee (the "Senior Note Indenture") shall have been
fully or partially paid (other than by the application of the proceeds of a
payment in respect of such bonds of the Thirty-Eighth Series), as the case may
be, or there shall have been deposited with the Senior Note Trustee pursuant to
the Senior Note 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 premium, if any, and/or interest on, the Senior Notes
(other than by the application of the proceeds of a payment in respect of such
bonds of the Thirty-Eighth Series).

            Upon payment of the principal of, and premium if any, and interest
due on the Senior Notes, 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 Senior Note Indenture (other than by the
application of the proceeds of a payment in respect of such bonds of the
Thirty-Eighth Series), bonds of the Thirty-Eighth Series in a principal amount
equal to the principal amount of Senior Notes 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 Thirty-Eighth Series shall be surrendered to and cancelled by
the Trustee. From and after the Release Date (as defined in the Senior Note
Indenture), the bonds of the Thirty-Eighth 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 Thirty-Eighth Series shall be
surrendered to and cancelled by the Trustee.

            SECTION 3. The Company covenants that the provisions of Section 36A
of the Indenture and of Section 1.02 of the Supplemental Indenture dated as of
July 1, 1948, which are to remain in effect so long as any bonds of the series
referred to in said Section shall be outstanding under the Indenture, shall
remain in full force and effect so long as any bonds of the Thirty-Eighth Series
shall be outstanding under the Indenture.

            SECTION 4. 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, other than as
set forth in the Mortgage. The Trustee shall not be responsible for the recitals
herein or in the bonds (except the Trustee's certificate of authentication), all
of which are made by the Company solely. Without limiting the generality of the
foregoing, the Trustee shall have no responsibility for, and shall incur no
liability with respect to, the form or substance of the Certificates or the form
or substance of any agreement under which any banking or other financial
institution receives the Deposit or makes the Payments nor shall the Trustee
have any responsibility, or incur any liability, with respect to the performance
of such banking or other financial institution under any such agreement.

            SECTION 5. As supplemented and amended by this Supplemental
Indenture, the Mortgage is in all respects ratified and confirmed, and the
Mortgage and this Supplemental Indenture shall be read, taken and construed as
one and the same instrument.

            SECTION 6. This Supplemental Indenture may be executed in several
counterparts and all such counterparts executed and delivered, each as an
original, shall constitute but one and the same instrument.

paragraph of this Indenture until a successor Trustee shall have become such
with respect to one or more series of Notes pursuant to the applicable

Section 102. Compliance Certificates and Opinions.

            Except as otherwise expressly provided in this Indenture, upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officer's Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

            Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

            (a) a statement that each Person signing such certificate or opinion
      has read such covenant or condition and the definitions herein relating
      thereto;

            (b) a brief statement as to the nature and scope of the examination

      certificate or opinion are based;

      such covenant or condition has been complied with; and

            (d) a statement as to whether, in the opinion of each such Person,
      such condition or covenant has been complied with.

Section 103. Form of Documents Delivered to Trustee.

            In any case where several matters are required to be certified by,
or covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters


                                       9
<PAGE>

and one or more other such Persons as to other matters, and any such Person may
certify or give an opinion as to such matters in one or several documents.

            Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such officer's certificate or opinion are
based are erroneous. Any such certificate or Opinion of Counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

            Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

            Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Company which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Notes issued under the authority of such defective document
or instrument shall nevertheless be the valid obligations of the Company
entitled to the benefits of this Indenture equally and ratably with all other
Outstanding Notes, except as aforesaid.

Section 104. Acts of Holders.

            (a) Any request, demand, authorization, direction, notice, consent,
      election, waiver or other action provided by this Indenture to be made,
      given or taken by Holders may be embodied in and evidenced by one or more
      instruments of substantially similar tenor signed by such Holders in
      person or by an agent duly appointed in writing or, alternatively, may be
      embodied in and evidenced by the record of Holders voting in favor
      thereof, either in person or by proxies duly appointed in writing, at any
      meeting of Holders duly called and held in accordance with the provisions
      of Article Fourteen, or a combination of such instruments and any such
      record. Except as herein otherwise expressly provided, such action shall
      become effective when such instrument or


                                       10
<PAGE>

      instruments or record or both are delivered to the Trustee and, where it
      is hereby expressly required, to the Company. Such instrument or
      instruments and any such record (and the action embodied therein and
      evidenced thereby) are herein sometimes referred to as the "Act" of the
      Holders signing such instrument or instruments and so voting at any such
      meeting. Proof of execution of any such instrument or of a writing
      appointing any such agent, or of the holding by any Person of a Note,
      shall be sufficient for any purpose of this Indenture and (subject to
      Section 1001) conclusive in favor of the Trustee and the Company, if made
      in the manner provided in this Section. The record of any meeting of
      Holders shall be proved in the manner provided in Section 1406.

            (b) The fact and date of the execution by any Person of any such
      instrument or writing may be proved by the affidavit of a witness of such
      execution or by a certificate of a notary public or other officer
      authorized by law to take acknowledgments of deeds, certifying that the
      individual signing such instrument or writing acknowledged to him the
      execution thereof or may be proved in any other manner which the Trustee
      and the Company deem sufficient. Where such execution is by a signer
      acting in a capacity other than his individual capacity, such certificate
      or affidavit shall also constitute sufficient proof of his authority.

            (c) The principal amount (except as otherwise contemplated in clause
      (y) of the proviso to the definition of Outstanding) and serial numbers of
      Notes held by any Person, and the date of holding the same, shall be
      proved by the Note Register.

            (d) Any request, demand, authorization, direction, notice, consent,
      election, waiver or other Act of a Holder shall bind every future Holder
      of the same Note and the Holder of every Note issued upon the registration
      of transfer thereof or in exchange therefor or in lieu thereof in respect
      of anything done, omitted or suffered to be done by the Trustee or the
      Company in reliance thereon, whether or not notation of such action is
      made upon such Note.

            (e) Until such time as written instruments shall have been delivered
      to the Trustee with respect to the requisite percentage of principal
      amount of Notes for the action contemplated by such instruments, any such
      instrument executed and delivered by or on behalf of a Holder may be
      revoked with respect to any or all of such Notes by written notice by such
      Holder or any subsequent Holder, proven in the manner in which such
      instrument was proven.

            (f) Notes of any series, or any Tranche thereof, authenticated and
      delivered after any Act of Holders may, and shall if required by the
      Trustee, bear a notation in form approved by the Trustee as to any action
      taken by such Act of Holders. If the Company shall so determine, new Notes
      of any series, or any Tranche thereof, so modified as to conform, in the
      opinion of the Trustee and the Company, to such action may be prepared and
      executed by the Company and authenticated and delivered by the Trustee in
      exchange for Outstanding Notes of such series or Tranche.

            (g) If the Company shall solicit from Holders any request, demand,
      authorization, direction, notice, consent, waiver or other Act, the
      Company may, at its


                                       11
<PAGE>

      option, fix in advance a record date for the determination of Holders
      entitled to give such request, demand, authorization, direction, notice,
      consent, waiver or other Act, but the Company shall have no obligation to
      do so. If such a record date is fixed, such request, demand,
      authorization, direction, notice, consent, waiver or other Act may be
      given before or after such record date, but only the Holders of record at
      the close of business on the record date shall be deemed to be Holders for
      the purposes of determining whether Holders of the requisite proportion of
      the Outstanding Notes have authorized or agreed or consented to such
      request, demand, authorization, direction, notice, consent, waiver or
      other Act, and for that purpose the Outstanding Notes shall be computed as
      of such record date.

Section 105. Notices, Etc. to Trustee and Company.

            Any request, demand, authorization, direction, notice, consent,
election, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with, the
Trustee by any Holder or by the Company, or the Company by the Trustee or by any
Holder, shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and delivered personally to an officer or

Section 106. Notice to Holders of Notes; Waiver.

            Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given, and shall be deemed given, to Holders if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Note Register, not later than the
latest date, and not earlier than the earliest date, prescribed for the giving
of such notice.

            In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
Holders by mail, then such notification as shall be made with the approval of
the Trustee shall constitute a sufficient notification for every purpose
hereunder. In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.

            Any notice required by this Indenture may be waived in writing by
the Person entitled to receive such notice, either before or after the event
otherwise to be specified therein, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

Section 107. Conflict with Trust Indenture Act.

            If any provision of this Indenture limits, qualifies or conflicts
with another provision hereof which is required or deemed to be included in this
Indenture by, or is otherwise governed by, any of the provisions of the Trust
Indenture Act, such other provision shall control; and if any provision hereof
otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall
control.

Section 108. Effect of Headings and Table of Contents.

            The Article and Section headings in this Indenture and the Table of
Contents are for convenience only and shall not affect the construction hereof.

Section 109. Successors and Assigns.

            All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

Section 110. Separability Clause.

            In case any provision in this Indenture or the Notes shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 111. Benefits of Indenture.

            Nothing in this Indenture or the Notes, express or implied, shall
give to any Person, other than the parties hereto, their successors hereunder,
and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

Section 112. Governing Law.

            This Indenture and the Notes shall be governed by and construed in
accordance with the laws of the State of New York, except to the extent that the
law of any other jurisdiction shall be mandatorily applicable.

Section 113. Legal Holidays.

            In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Note shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Notes
other than a provision in Notes of any series, or any Tranche thereof, or in the
indenture supplemental hereto, Board Resolution or Officer's Certificate which
establishes the terms of the Notes of such series or Tranche, which specifically
states that such provision shall apply in lieu of this Section) payment of
interest or principal and premium, if any, need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, or at the Stated Maturity, and, if such payment
is made or duly provided for on such Business Day, no interest shall accrue on
the amount so payable for the period from and after such Interest Payment Date,
Redemption Date or Stated Maturity, as the case may be, to such Business Day.

Section 303. Execution, Authentication, Delivery and Dating.

            Unless otherwise provided as contemplated by Section 301 with
respect to any series of Notes, or any Tranche thereof, the Notes shall be
executed on behalf of the Company by an Authorized Officer and may have the
corporate seal of the Company affixed thereto or reproduced thereon attested by
any other Authorized Officer. The signature of any or all of these officers on
the Notes may be manual or facsimile.

            Notes bearing the manual or facsimile signatures of individuals who
were at the time of execution Authorized Officers of the Company shall bind the
Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Notes or did
not hold such offices at the date of such Notes.

            The Trustee shall authenticate and deliver Notes of a series, for
original issue, at one time or from time to time in accordance with the Company
Order referred to below, upon receipt by the Trustee of:

            (a) the instrument or instruments establishing the form or forms and
      terms of such series, as provided in Sections 201 and 301;

            (b) a Company Order requesting the authentication and delivery of
      such Notes and, to the extent that the terms of such Notes shall not have
      been established in an indenture supplemental hereto or in a Board
      Resolution, or in an Officer's Certificate pursuant to a supplemental
      indenture or Board Resolution, all as contemplated by Sections 201 and
      301, either (i) establishing such terms or (ii) in the case of Notes of a
      series subject to a Periodic Offering, specifying procedures, acceptable
      to the Trustee, by which such terms are to be established (which
      procedures may provide, to the extent acceptable to the Trustee, for
      authentication and delivery pursuant to oral or electronic instructions
      from the Company or any agent or agents thereof, which oral instructions
      are to be promptly confirmed electronically or in writing), in either case
      in accordance with the instrument or instruments delivered pursuant to
      clause (a) above; the Notes of such series, executed on behalf of the
      Company by an Authorized Officer;

            (c) if prior to the Release Date, Senior Note First Mortgage Bonds
      of a series conforming to the requirements of Sections 401 and 402 hereof;

            (d) the Notes of such series, executed on behalf of the Company by
      an Authorized Officer;

            (e) an Opinion of Counsel to the effect that:

                  (i) the form or forms of such Notes have been duly authorized
            by the Company and have been established in conformity with the
            provisions of this Indenture;

                  (ii) the terms of such Notes have been duly authorized by the
            Company and have been established in conformity with the provisions
            of this Indenture; and


                                       19
<PAGE>

                  (iii) assuming authentication and delivery by the Trustee and
            subject to any conditions specified in such Opinion of Counsel, such
            Notes will have been duly issued under the Indenture and will be
            legal, valid and binding obligations of the Company enforceable in
            accordance with their terms, except as limited by bankruptcy,
            insolvency or other laws affecting mortgagees' and other creditors'
            rights and general equitable principles;

                  (iv) if prior to the Release Date, the Senior Note First
            Mortgage Bonds being delivered to the Trustee in connection with the
            issuance of such Notes, assuming authentication by the Mortgage
            Trustee in accordance with the First Mortgage and delivery to the
            Trustee and subject to any conditions specified in such Opinion of
            Counsel, will have been duly authorized by the Company and duly
            issued under the First Mortgage and will constitute the legal, valid
            and binding obligations of the Company, enforceable in accordance
            with their terms, except as limited by bankruptcy, insolvency or
            other laws affecting mortgagees' and other creditors' rights and
            general equitable principles, and such Senior Note First Mortgage
            Bonds are entitled to the benefits of the security afforded by the
            First Mortgage, and are secured equally and ratably with all other
            bonds outstanding thereunder, except insofar as any sinking or other
            fund may afford additional security for the bonds of any particular
            series;

provided, however, that, with respect to Notes of a series subject to a Periodic
Offering, the Trustee shall be entitled to receive such Opinion of Counsel only
once at or prior to the time of the first authentication of such Notes (provided
that such Opinion of Counsel addresses the authentication and delivery of all
Notes of such series) and that in lieu of the opinions described in clauses (ii)
and (iii) above Counsel may opine that:

                  (x) when the terms of such Notes shall have been established
            pursuant to a Company Order or Orders or pursuant to such procedures
            (acceptable to the Trustee) as may be specified from time to time by
            a Company Order or Orders, all as contemplated by and in accordance
            with the instrument or instruments delivered pursuant to clause (a)
            above, such terms will have been duly authorized by the Company and
            will have been established in conformity with the provisions of this
            Indenture; and

                  (y) such Notes, when authenticated and delivered by the
            Trustee in accordance with this Indenture and the Company Order or
            Orders or specified procedures referred to in paragraph (x) above
            and issued and delivered by the Company in the manner and subject to
            any conditions specified in such Opinion of Counsel, will have been
            duly issued under this Indenture and will constitute valid and
            legally binding obligations of the Company, entitled to the benefits
            provided by the Indenture, and enforceable in accordance with their
            terms, subject, as to enforcement, to laws relating to or affecting
            generally the enforcement of creditors' rights, including, without
            limitation, bankruptcy and insolvency laws and to general principles
            of equity (regardless of whether such enforceability is considered
            in a proceeding in equity or at law).


                                       20
<PAGE>

            With respect to Notes of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Notes, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, at or prior to the time of the first authentication of Notes of such
series unless and until such opinion or other documents have been superseded or
revoked or expire by their terms. In connection with the authentication and
delivery of Notes of a series subject to a Periodic Offering, the Trustee shall
be entitled to assume that the Company's instructions to authenticate and
deliver such Notes do not violate any rules, regulations or orders of any
Governmental Authority having jurisdiction over the Company.

            If the form or terms of the Notes of any series have been
established by or pursuant to a Board Resolution or an Officer's Certificate as
permitted by Sections 201 or 301, the Trustee shall not be required to
authenticate such Notes if the issuance of such Notes pursuant to this Indenture
will materially or adversely affect the Trustee's own rights, duties or
immunities under the Notes and this Indenture or otherwise in a manner which is
not reasonably acceptable to the Trustee.

            Unless otherwise specified as contemplated by Section 301 with
respect to any series of Notes, or any Tranche thereof, each Note shall be dated
the date of its authentication.

            Unless otherwise specified as contemplated by Section 301 with
respect to any series of Notes, or any Tranche thereof, no Note shall be
entitled to any benefit under this Indenture or be valid or obligatory for any
purpose unless there appears on such Note a certificate of authentication
substantially in the form provided for herein executed by the Trustee or its
agent by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder and is entitled to the benefits of this
Indenture. Notwithstanding the foregoing, if any Note shall have been
authenticated and delivered hereunder to the Company, or any Person acting on
its behalf, but shall never have been issued and sold by the Company, and the
Company shall deliver such Note to the Note Registrar for cancellation as
provided in Section 309 together with a written statement (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) stating
that such Note has never been issued and sold by the Company, for all purposes
of this Indenture such Note shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits hereof.

Section 304. Temporary Notes.

            Pending the preparation of definitive Notes of any series, or any
Tranche thereof, the Company may execute, and upon Company Order the Trustee
shall authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Notes in lieu of which they are
issued, with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Notes may determine, as evidenced by
their execution of such Notes; provided, however, that temporary Notes need not
recite specific redemption, sinking fund, conversion or exchange provisions.


                                       21
<PAGE>

            Unless otherwise specified as contemplated by Section 301 with
respect to the Notes of any series, or any Tranche thereof, after the
preparation of definitive Notes of such series or Tranche, the temporary Notes
of such series or Tranche shall be exchangeable, without charge to the Holder
thereof, for definitive Notes of such series or Tranche, upon surrender of such
temporary Notes at the office or agency of the Company maintained pursuant to
Section 702 in a Place of Payment for such Notes. Upon such surrender of
temporary Notes, the Company shall, except as aforesaid, execute and the Trustee
shall authenticate and deliver in exchange therefor definitive Notes of the same
series and Tranche, of authorized denominations and of like tenor and aggregate
principal amount.

            Until exchanged in full as hereinabove provided, temporary Notes
shall in all respects be entitled to the same benefits under this Indenture as
definitive Notes of the same series and Tranche and of like tenor authenticated
and delivered hereunder.

Section 305. Registration, Registration of Transfer and Exchange.

            The Company shall cause to be kept in each office designated
pursuant to Section 702, with respect to the Notes of each series or any Tranche
thereof, a register (all registers kept in accordance with this Section being
collectively referred to as the "Note Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes of such series or Tranche and the registration of transfer
thereof. The Company shall designate one Person to maintain the Note Register
for the Notes of each series on a consolidated basis, and such Person is
referred to herein, with respect to such series, as the "Note Registrar."
Anything herein to the contrary notwithstanding, the Company may designate one
or more of its offices as an office in which a register with respect to the
Notes of one or more series, or any Tranche or Tranches thereof, shall be
maintained, and the Company may designate itself the Note Registrar with respect
to one or more of such series. The Note Register shall be open for inspection by
the Trustee and the Company at all reasonable times.

            Except as otherwise specified as contemplated by Section 301 with
respect to the Notes of any series, or any Tranche thereof, upon surrender for
registration of transfer of any Note of such series or Tranche at the office or
agency of the Company maintained pursuant to Section 702 in a Place of Payment
for such series or Tranche, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes of the same series and Tranche, of authorized
denominations and of like tenor and aggregate principal amount.

            Except as otherwise specified as contemplated by Section 301 with
respect to the Notes of any series, or any Tranche thereof, any Note of such
series or Tranche may be exchanged at the option of the Holder, for one or more
new Notes of the same series and Tranche, of authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency. Whenever any Notes are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Notes that the Holder making the exchange is entitled to receive.


                                       22
<PAGE>

            All Notes delivered upon any registration of transfer or exchange of
Notes shall be valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

            Every Note presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company, the Trustee or the Note
Registrar) be duly endorsed or shall be accompanied by a written instrument of
transfer in form satisfactory to the Company, the Trustee or the Note Registrar,
as the case may be, duly executed by the Holder thereof or his attorney duly
authorized in writing.

            Unless otherwise specified as contemplated by Section 301 with
respect to Notes of any series, or any Tranche thereof, no service charge shall
be made for any registration of transfer or exchange of Notes, but the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Notes, other than exchanges pursuant to Section 304, 506 or 1306 not
involving any transfer.

            The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Notes of any series, or any
Tranche thereof, during a period of 15 days immediately preceding the day of the
mailing of a notice of redemption of the Notes of such series or Tranche or (b)
any Note so selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part.

Section 306. Mutilated, Destroyed, Lost and Stolen Notes.

            If any mutilated Note is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Note of the same series, and of like tenor and principal amount
and bearing a number not contemporaneously outstanding.

            If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Note and (b) such security or indemnity as may be reasonably
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such Note is
held by a Person purporting to be the owner of such Note, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Note, a new Note of the same series and Tranche, and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

            Notwithstanding the foregoing, in case any such mutilated,
destroyed, lost or stolen Note has become or is about to become due and payable,
the Company in its discretion may, instead of issuing a new Note, pay such Note.

            Upon the issuance of any new Note under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the fees and expenses of the Trustee) connected
therewith.


                                       23
<PAGE>

            Every new Note of any series issued pursuant to this Section in lieu
of any destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone other than the Holder of
such new Note, and any such new Note shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Notes of such
series duly issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

Section 307. Payment of Interest; Interest Rights Preserved.

            Unless otherwise specified as contemplated by Section 301 with
respect to the Notes of any series, or any Tranche thereof, interest on any Note
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record
Date for such interest payment.

            Any interest on any Note of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the related Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (a) or (b) below:

            (a) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Notes of such series (or their
      respective Predecessor Notes) are registered at the close of business on a
      date (herein called a "Special Record Date") for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Note of such series and the date of
      the proposed payment, and at the same time the Company shall deposit with
      the Trustee an amount of money equal to the aggregate amount proposed to
      be paid in respect of such Defaulted Interest or shall make arrangements
      satisfactory to the Trustee for such deposit prior to the date of the
      proposed payment, such money when deposited to be held in trust for the
      benefit of the Persons entitled to such Defaulted Interest as in this
      clause provided. Thereupon the Trustee shall fix a Special Record Date for
      the payment of such Defaulted Interest which shall be not more than 15
      days and not less than 10 days prior to the date of the proposed payment
      and not less than 10 days after the receipt by the Trustee of the notice
      of the proposed payment. The Trustee shall promptly notify the Company of
      such Special Record Date and, in the name and at the expense of the
      Company, shall promptly cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to each Holder of Notes of such series at the
      address of such Holder as it appears in the Note Register, not less than
      10 days prior to such Special Record Date. Notice of the proposed payment
      of such Defaulted Interest and the Special Record Date therefor having
      been so mailed, such Defaulted Interest shall be paid to the Persons in
      whose names the Notes of such series (or their


                                       24
<PAGE>

      respective Predecessor Notes) are registered at the close of business on
      such Special Record Date.

            (b) The Company may make payment of any Defaulted Interest on the
      Notes of any series in any other lawful manner not inconsistent with the
      requirements of any securities exchange on which such Notes may be listed,
      and upon such notice as may be required by such exchange, if, after notice
      given by the Company to the Trustee of the proposed payment pursuant to
      this clause, such manner of payment shall be deemed practicable by the
      Trustee.

            Subject to the foregoing provisions of this Section and Section 305,
each Note delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Note shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Note.

Section 308. Persons Deemed Owners.

            Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Note is registered as the absolute owner of such
Note for the purpose of receiving payment of principal of and premium, if any,
and (subject to Sections 305 and 307) interest, if any, on such Note and for all
other purposes whatsoever, whether or not such Note be overdue, and neither the

            (e) the place or places where such Notes are to be surrendered for

"mandatory sinking fund payment", and any payment in excess of such minimum
amount provided for by the terms of Notes of any series, or any Tranche thereof,

such Notes, in each case in satisfaction of all or any part of such mandatory
sinking fund payment; provided, however, that no Notes shall be applied in
satisfaction of a mandatory sinking fund payment if such Notes shall have been

      and that such Notes have not previously been so credited, and the Company
      shall also deliver to the Trustee any Notes to be so delivered.

            If the Company shall not have delivered such Officer's Certificate
and, to the extent applicable, all such Notes, on or prior to the 45th day prior
to such sinking fund payment date, the sinking fund payment for such series or
Tranche in respect of such sinking fund payment date shall be made entirely in
cash in the amount of the mandatory sinking fund payment. Not less than 30 days
before each such sinking fund payment date the Trustee shall select the Notes to
be redeemed upon such sinking fund payment date in the manner specified in
Section 503 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 504. Such
notice having been duly


                                       34

given, the redemption of such Notes shall be made upon the terms and in the
manner stated in Sections 505 and 506.

                                   ARTICLE VII

                                    Covenants

Section 701. Payment of Principal, Premium and Interest.

            The Company shall pay the principal of and premium, if any, and
interest, if any, on the Notes of each series in accordance with the terms of
such Notes and this Indenture.

Section 702. Maintenance of Office or Agency.

            The Company shall maintain in each Place of Payment for the Notes of
each series, or any Tranche thereof, an office or agency where payment of such
Notes shall be made, where the registration of transfer or exchange of such
Notes may be effected and where notices and demands to or upon the Company in
respect of such Notes and this Indenture may be served. The Company shall give
prompt written notice to the Trustee of the location, and any change in the
location, of each such office or agency and prompt notice to the Holders of any
such change in the manner specified in Section 106. If at any time the Company
shall fail to maintain any such required office or agency in respect of Notes of
any series, or any Tranche thereof, or shall fail to furnish the Trustee with
the address thereof, payment of such Notes shall be made, registration of
transfer or exchange thereof may be effected and notices and demands in respect
thereof may be served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent for all such purposes in any
such event.

            The Company may also from time to time designate one or more other
offices or agencies with respect to the Notes of one or more series, or any
Tranche thereof, for any or all of the foregoing purposes and may from time to
time rescind such designations; provided, however, that, unless otherwise
specified as contemplated by Section 301 with respect to the Notes of such
series or Tranche no such designation or rescission shall in any manner relieve
the Company of its obligation to maintain an office or agency for such purposes
in each Place of Payment for such Notes in accordance with the requirements set
forth above. The Company shall give prompt written notice to the Trustee, and
prompt notice to the Holders in the manner specified in Section 106, of any such
designation or rescission and of any change in the location of any such other
office or agency.

            Anything herein to the contrary notwithstanding, any office or
agency required by this Section may be maintained at an office of the Company,
in which event the Company shall perform all functions to be performed at such
office or agency.

Section 703. Money for Notes Payments to be Held in Trust.

            If the Company shall at any time act as its own Paying Agent with
respect to the Notes of any series, or any Tranche thereof, it shall, on or
before each due date of the principal of and premium, if any, and interest, if
any, on any of such Notes, segregate and hold in trust for the


                                       35
<PAGE>

benefit of the Persons entitled thereto a sum sufficient to pay the principal
and premium or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided. The Company shall promptly
notify the Trustee of any failure by the Company (or any other obligor on such
Notes) to make any payment of principal of or premium, if any, or interest, if
any, on such Notes.

            Whenever the Company shall have one or more Paying Agents for the
Notes of any series, or any Tranche thereof, it shall, on or before each due
date of the principal of and premium, if any, and interest, if any, on such
Notes, deposit with such Paying Agents sums sufficient (without duplication) to
pay the principal and premium or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company shall
promptly notify the Trustee of any failure by it so to act.

            The Company shall cause each Paying Agent for the Notes of any
series, or any Tranche thereof, other than the Company or the Trustee, to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent shall:

            (a) hold all sums held by it for the payment of the principal of and
      premium, if any, or interest, if any, on such Notes in trust for the
      benefit of the Persons entitled thereto until such sums shall be paid to
      such Persons or otherwise disposed of as herein provided;

            (b) give the Trustee notice of any failure by the Company (or any
      other obligor upon such Notes) to make any payment of principal of or
      premium, if any, or interest, if any, on such Notes; and

            (c) at any time during the continuance of any such default, upon the
      written request of the Trustee, forthwith pay to the Trustee all sums so
      held in trust by such Paying Agent and furnish to the Trustee such
      information as it possesses regarding the names and addresses of the
      Persons entitled to such sums.

            The Company may at any time pay, or by Company Order direct any
Paying Agent to pay, to the Trustee all sums held in trust by the Company or
such Paying Agent, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by the Company or such Paying Agent and, if
so stated in a Company Order delivered to the Trustee, in accordance with the
provisions of Article Eight; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of and premium,
if any, or interest, if any, on any Note and remaining unclaimed for two years
after such principal and premium, if any, or interest has become due and payable
shall be paid to the Company on Company Request, or, if then held by the
Company, shall be discharged from such trust; and, upon such payment or
discharge, the Holder of such Note shall, as an unsecured general creditor and
not as a Holder of


                                       36
<PAGE>

an Outstanding Note, look only to the Company for payment of the amount so due
and payable and remaining unpaid, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such payment to the
Company, may at the expense of the Company cause to be mailed, on one occasion
only, notice to such Holder that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such mailing, any unclaimed balance of such money then remaining will be paid to
the Company.

Section 704. Corporate Existence.

            Subject to the rights of the Company under Article Twelve, the
Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence.

Section 705. Maintenance of Properties.

            The Company shall cause (or, with respect to property owned in
common with others, make reasonable effort to cause) all its properties used or
useful in the conduct of its business to be maintained and kept in good
condition, repair and working order and shall cause (or, with respect to
property owned in common with others, make reasonable effort to cause) to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as, in the judgment of the Company, may be necessary so that the
business carried on in connection therewith may be properly conducted; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing, or causing the discontinuance of, the operation and maintenance
of any of its properties if such discontinuance is, in the judgment of the
Company, desirable in the conduct of its business.

Section 706. Annual Officer's Certificate as to Compliance.

            Not later than June 1 in each year, commencing June 1, 2000, the
Company shall deliver to the Trustee an Officer's Certificate, which need not
comply with Section 102, executed by the principal executive officer, the
principal financial officer or the principal accounting officer of the Company,
stating whether to such officer's knowledge, the Company is in compliance with
all conditions and covenants under this Indenture, such compliance to be
determined without regard to any period of grace or requirement of notice under
this Indenture, and making any other statements as may be required by the
provisions of Section 314(a)(4) of the Trust Indenture Act.

Section 707. Waiver of Certain Covenants.

            The Company may omit in any particular instance to comply with any
term, provision or condition set forth in (a) Section 702 or any additional
covenant or restriction specified with respect to the Notes of any series, or
any Tranche thereof, as contemplated by Section 301 if before the time for such
compliance the Holders of at least a majority in aggregate principal amount of
the Outstanding Notes of all series and Tranches with respect to which
compliance with Section 702 or such additional covenant or restriction is to be
omitted,


                                       37
<PAGE>

considered as one class, shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition and (b) Section 704, 705, 706 or Article Twelve if before
the time for such compliance the Holders of at least a majority in principal
amount of Notes Outstanding under this Indenture shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition; but, in the case of (a) or (b), no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

Section 708. Recording, Filing, etc.; Opinions of Counsel.

            The Company will (and the Trustee shall be under no duty to) cause
this Indenture, any indentures supplemental to this Indenture, any financing or
continuation statements, and any other documents, to be promptly recorded and

      interest of the Trustee intended to be created by this Indenture for the
      benefit of the Holders from time to time in the Senior Note First Mortgage
      Bonds, and reciting the details of such action, or stating that, in the
      opinion of such counsel, no such action is necessary to perfect or make
      such security interest effective and stating what, if any, action of the
      foregoing character may reasonably be expected to become necessary prior
      to the next succeeding July 15 to maintain, perfect and make such security
      interest effective; and

Section 709. Liens.

            (a) From and after the Release Date and so long as any Notes are
      Outstanding, the Company will not issue, assume, or guarantee (including
      any contingent obligation to purchase) any Debt secured by any mortgage,
      security interest, pledge, or lien (herein referred to as a "Lien") of or
      upon any Operating Property of the Company, whether owned at the date of
      the Indenture or thereafter acquired, and will not permit to exist any
      Debt secured by a Lien on any Operating Property created on or prior to
      the Release Date, without in any such case effectively securing, on the
      later to occur of the issuance, assumption, or guarantee of any such Debt

                  of the properties of such corporation or a division thereof as
                  an entirety or substantially as an entirety to the Company,
                  provided that such Lien as a result of such merger,
                  consolidation, sale, lease, or other disposition is not
                  extended to property owned by the Company immediately prior

                  contemporaneously with, or within eighteen (18) months after,
                  such acquisition or completion of construction, development,
                  or substantial repair, alteration, or improvement or within
                  six (6) months thereafter pursuant to a commitment for

                  State thereof, or for the benefit of holders of securities
                  issued by any such entity, to secure any Debt incurred for the
                  purpose of financing all or any part of the purchase price or
                  the cost of constructing, developing,


                                       39

            (5)   any extension, renewal or replacement (or successive
                  extensions, renewals, or replacements), in whole or in part,
                  of any Lien referred to in the foregoing clauses (1) to (4),
                  inclusive; provided, however, that the principal amount of
                  Debt secured thereby and not otherwise authorized by said
                  clauses (1) to (4), inclusive, shall not exceed the principal
                  amount of Debt, plus any premium or fee payable in connection
                  with any such extension, renewal, or replacement, so secured
                  at the time of such extension, renewal, or replacement.

            (b) Notwithstanding the provisions of Section 709(a), from and after
      the Release Date and so long as any Notes are Outstanding, the Company may
      issue, assume, or guarantee Debt, or permit to exist Debt, secured by
      Liens which would otherwise be subject to the restrictions of Section
      709(a) up to an aggregate principal amount that, together with the
      principal amount of all other Debt of the Company secured by Liens (other
      than Liens permitted by Section 709(a) that would otherwise be subject to
      the foregoing restrictions) and the Value of all Sale and Lease-Back
      Transactions in existence at such time (other than (i) any Sale and
      Lease-Back Transaction that, if such Sale and Lease-Back Transaction had
      been a Lien, would have been permitted by Section 709(a), (ii) Sale and
      Lease-Back Transactions permitted by Section 710 because the commitment by
      or on behalf of the purchaser was obtained no later than eighteen (18)
      months after the later of events described in (i) or (ii) of Section 710,
      and (iii) Sale and Lease-Back Transactions as to which application of
      amounts have been made in accordance with clause (z) of Section 710), does
      not at the time exceed the greater of ten percent (10%) of Net Tangible
      Assets or ten percent (10%) of Capitalization.

            (c) If at any time the Company shall issue, assume, or guarantee any
      Debt secured by any Lien and if Section 709(a) requires that the
      Outstanding Notes be secured equally and ratably with such Debt, the
      Company will promptly execute, at its expense, any instruments necessary
      to so equally and ratably secure the Outstanding Notes and deliver the
      same to the Trustee along with:

            (1)   An Officers' Certificate stating that the covenant of the
                  Company contained in Section 709(a) has been complied with;
                  and

            (2)   An Opinion of Counsel to the effect that the Company has
                  complied with the covenant contained in Section 709(a), and
                  that any instrument executed by the Company in the performance
                  of such covenant complies with the requirements of such
                  covenant.

            In the event that the Company shall hereafter secure Outstanding
      Notes equally and ratably with any other obligation or indebtedness
      (including other Notes) pursuant to the provisions of this Section 709,
      the Trustee is hereby authorized to enter into an indenture or agreement
      supplemental hereto and to take such action, if any, as it may, in


                                       40
<PAGE>

      its sole and absolute discretion, deem advisable to enable it to enforce
      effectively the rights of the Holders of Outstanding Notes so secured,
      equally and ratably with such other obligation or indebtedness.

Section 710. Sale and Lease-Back Transactions.

            From and after the Release Date and so long as any Notes are
outstanding, the Company will not enter into any Sale and Lease-Back Transaction
with respect to any Operating Property and will not permit to remain in effect
any Sale and Lease-Back Transaction entered into on or prior to the Release Date
with respect to any Operating Property if, in any case, the commitment by or on
behalf of the purchaser is or was obtained more than eighteen (18) months after
the later of (i) the completion of the acquisition, construction, or development
of such Operating Property or (ii) the placing in operation of such Operating
Property or of such Operating Property as constructed, developed, or
substantially repaired, altered, or improved, unless (x) the Company would be

Notes or (y) the Company would be entitled pursuant to Section 709(b), after
giving effect to such Sale and Lease-Back Transaction, to incur $1.00 of
additional Debt secured by Liens (other than Liens permitted by Section 709(a))
or (z) the Company shall apply or cause to be applied, in the case of a sale or
transfer for cash, an amount equal to the net proceeds thereof (but not less
than the fair value (as determined by the Company's Chief Financial Officer) of
such Operating Property at the date of such sale or transfer) and, in the case
of a sale or transfer otherwise than for cash, an amount equal to the fair value
(as determined by the Board of Directors) of the Operating Property so leased,
to the retirement, within one hundred eighty (180) days after the later to occur
of the effective date of such Sale and Lease-Back Transaction or the Release
Date, of Notes or other Debt of the Company ranking equally with, the Notes;
provided, however, that any such retirement of Notes shall be in accordance with
the terms and provisions of the Indenture and the Notes; provided, further, that
the amount to be applied to such retirement of Notes or other Debt shall be
reduced by an amount equal to the sum of (a) an amount equal to the redemption
price with respect to Notes delivered within such one hundred eighty (180)-day
period to the Trustee for retirement and cancellation and (b) the principal
amount, plus any premium or fee paid in connection with any redemption in
accordance with the terms of other Debt voluntarily retired by the Company
within such one hundred eighty (180)-day period, excluding in each case
retirements pursuant to mandatory sinking fund or prepayment provisions and
payments at maturity.

            requirements set forth in clause (b) above have been satisfied; and

                  (z) if such deposit shall have been made prior to the Maturity
            of such Notes, an Officer's Certificate stating the Company's
            intention that, upon delivery of such Officer's Certificate, its
            indebtedness in respect of such Notes or portions thereof will have
            been satisfied and discharged as contemplated in this Section.

If the Company shall make any deposit of money and/or Eligible Obligations with
respect to any Notes, or any portion of the principal amount thereof, as
contemplated by this section, the Company shall not deliver an Officer's
Certificate described in clause (z) above unless the Company shall also deliver
to the Trustee, together with such Officer's Certificate, an Opinion of Counsel
to the effect that, as a result of a change in law occurring after the date of
this Indenture, the Holders of such Notes, or portions thereof, will not
recognize income, gain or loss for United States federal income tax purposes as
a result of the satisfaction and discharge of the Company's indebtedness in
respect thereof and will be subject to United States federal income tax on the


                                       42
<PAGE>

same amounts, at the same times and in the same manner as if such satisfaction
and discharge had not been effected.

            Upon the deposit of money or Eligible Obligations, or both, in
accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon receipt of a Company Request,
acknowledge in writing that the Note or Notes or portions thereof with respect
to which such deposit was made are deemed to have been paid for all purposes of
this Indenture and that the entire indebtedness of the Company in respect
thereof has been satisfied and discharged as contemplated in this Section. In
the event that all of the conditions set forth in the preceding paragraph shall
have been satisfied in respect of any Notes or portions thereof except that, for
any reason, the Officer's Certificate specified in clause (z) shall not have
been delivered, such Notes or portions thereof shall nevertheless be deemed to
have been paid for all purposes of this Indenture, and the Holders of such Notes
or portions thereof shall nevertheless be no longer entitled to the benefits of
this Indenture or of any of the covenants of the Company under Article Seven
(except the covenants contained in Sections 702 and 703) or any other covenants
made in respect of such Notes or portions thereof as contemplated by Section
301, but the indebtedness of the Company in respect of such Notes or portions
thereof shall not be deemed to have been satisfied and discharged prior to
Maturity for any other purpose, and the Holders of such Notes or portions
thereof shall continue to be entitled to look to the Company for payment of the
indebtedness represented thereby; and, upon Company Request, the Trustee shall
acknowledge in writing that such Notes or portions thereof are deemed to have
been paid for all purposes of this Indenture.

            If payment at Stated Maturity of less than all of the Notes of any
series, or any Tranche thereof, is to be provided for in the manner and with the
effect provided in this Section, the Trustee shall select such Notes, or
portions of principal amount thereof, in the manner specified by Section 503 for
selection for redemption of less than all the Notes of a series or Tranche.

            In the event that Notes which shall be deemed to have been paid for
purposes of this Indenture, and, if such is the case, in respect of which the
Company's indebtedness shall have been satisfied and discharged, all as provided
in this Section do not mature and are not to be redeemed within the sixty (60)
day period commencing with the date of the deposit of moneys or Eligible
Obligations, as aforesaid, the Company shall, as promptly as practicable, give a
notice, in the same manner as a notice of redemption with respect to such Notes,
to the Holders of such Notes to the effect that such deposit has been made and
the effect thereof.

            Notwithstanding that any Notes shall be deemed to have been paid for
purposes of this Indenture, as aforesaid, the obligations of the Company and the
Trustee in respect of such Notes under Sections 304, 305, 306, 504, 603 (as to
notice of redemption), 702, 703, 1007, 1014 and 1015 and this Article Eight
shall survive.

            To the extent Notes are deemed paid and discharged pursuant to this
Section 801, the obligation of the Company to make payment with respect to the
principal of and premium, if any, and interest on the related Senior Note First
Mortgage Bonds shall be satisfied and discharged, and such Senior Note First
Mortgage Bonds shall cease to secure the Notes in any manner but shall continue
to be held by the Trustee until the Release Date.


                                       43
<PAGE>

            If the Company shall have paid or caused to be paid the principal of
and premium, if any, and interest on any Note, as and when the same shall have
become due and payable or the Company shall have delivered to the Trustee or the
Note Registrar for cancellation any Outstanding Note, such Note shall cease to
be entitled to any lien, benefit or security under this Indenture. Upon a Note
of any series ceasing to be entitled to any lien, benefit or security under this
Indenture, the obligation of the Company to make payment with respect to
principal of and premium, if any, and interest on a principal amount of the
related series of Senior Note First Mortgage Bonds equal to the principal amount
of such Note shall be satisfied and discharged and such portion of the principal
amount of such Senior Note First Mortgage Bonds shall cease to secure such Note
in any manner, but such Senior Note First Mortgage Bonds shall continue to be
held by the Trustee until the Release Date.

            The Company shall pay, and shall indemnify the Trustee or any Paying
Agent with which Eligible Obligations shall have been deposited as provided in
this Section against, any tax, fee or other charge imposed on or assessed
against such Eligible Obligations or the principal or interest received in
respect of such Eligible Obligations, including, but not limited to, any such
tax payable by any entity deemed, for tax purposes, to have been created as a
result of such deposit.

            Anything herein to the contrary notwithstanding, (a) if, at any time
after a Note would be deemed to have been paid for purposes of this Indenture,
and, if such is the case, the Company's indebtedness in respect thereof would be
deemed to have been satisfied or discharged, pursuant to this Section (without
regard to the provisions of this paragraph), the Trustee or any Paying Agent, as
the case may be, shall be required to return the money or Eligible Obligations,
or combination thereof, deposited with it as aforesaid to the Company or its
representative under any applicable Federal or State bankruptcy, insolvency or
other similar law, such Note shall thereupon be deemed retroactively not to have
been paid and any satisfaction and discharge of the Company's indebtedness in
respect thereof (and in respect of the related Senior Note First Mortgage Bonds)
shall retroactively be deemed not to have been effected, such Note shall be
deemed to remain Outstanding, and such Note shall continue to be secured by the
related Senior Note First Mortgage Bond until the Release Date and (b) any
satisfaction and discharge of the Company's indebtedness in respect of any Note
shall be subject to the provisions of the last paragraph of Section 703.

Section 802. Satisfaction and Discharge of Indenture.

            This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

            (a) no Notes remain Outstanding hereunder; and

            (b) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company;

provided, however, that if, in accordance with the last paragraph of Section
801, any Note, previously deemed to have been paid for purposes of this
Indenture, shall be deemed


                                       44
<PAGE>

retroactively not to have been so paid, this Indenture shall thereupon be deemed
retroactively not to have been satisfied and discharged, as aforesaid, and to
remain in full force and effect, and the Company shall execute and deliver such
instruments as the Trustee shall reasonably request to evidence and acknowledge
the same.

            Notwithstanding the satisfaction and discharge of this Indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 304,
305, 306, 504, 603 (as to notice of redemption), 702, 703, 1007, 1014 and 1015
and this Article Eight shall survive.

            Upon satisfaction and discharge of this Indenture as provided in
this Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 1007, any and all money, Notes and other
property then held by the Trustee for the benefit of the Holders of the Notes
other than money and Eligible Obligations held by the Trustee pursuant to
Section 803.

Section 803. Application of Trust Money.

            Neither the Eligible Obligations nor the money deposited pursuant to
Section 801, nor the principal or interest payments on any such Eligible
Obligations, shall be withdrawn or used for any purpose other than, and shall be
held in trust for, the payment of the principal of, and premium, if any, and
interest, if any, on, the Notes or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions
of Section 703; provided, however, that, so long as there shall not have
occurred and be continuing an Event of Default, or an event which, with the
giving of notice or the passage of time, would become an Event of Default, any
cash received from such principal or interest payments on such Eligible
Obligations, if not then needed for such purpose, shall, to the extent
practicable, be invested in Eligible Obligations of the type described in clause
(b) in the first paragraph of Section 801 maturing at such times and in such
amounts as shall be sufficient to pay when due the principal of and premium, if
any, and interest, if any, due and to become due on such Notes or portions
thereof on and prior to the Maturity thereof, and interest earned from such
reinvestment shall be paid over to the Company as received, free and clear of
any trust, lien or pledge under this Indenture except the lien provided by
Section 1007; and provided, further, that, so long as there shall not have
occurred and be continuing an Event of Default, or an event which, with the
giving of notice or the passage of time, would become an Event of Default, any
moneys held in accordance with this Section on the Maturity of all such Notes in
excess of the amount required to pay the principal of and premium, if any, and
interest, if any, then due on such Notes shall be paid over to the Company free
and clear of any trust, lien or pledge under this Indenture except the lien
provided by Section 1007; and provided, further, that if an Event of Default, or
an event which, with the giving of notice or the passage of time, would become
an Event of Default, shall have occurred and be continuing, moneys to be paid
over to the Company pursuant to this Section shall be held until such Event of
Default, or event which, with the giving of notice or the passage of time, would
become an Event of Default, shall have been waived or cured.

                           Events of Default; Remedies

Section 901. Events of Default.

            "Event of Default", wherever used herein with respect to Notes of
any series, means any one of the following events:

            (a) failure to pay interest, if any, on any Note of such series
      within thirty (30) days after the same becomes due and payable; or

            (b) failure to pay the principal of or premium, if any, on any Note
      of such series when due and payable; or

            (c) failure to perform or breach of any covenant or warranty of the
      Company in this Indenture (other than a covenant or warranty a default in
      the performance of which or breach of which is elsewhere in this Section
      specifically dealt with or which has expressly been included in this
      Indenture solely for the benefit of one or more series of Notes other than
      such series) for a period of 60 days after there has been given, by
      registered or certified mail, to the Company by the Trustee, or to the
      Company and the Trustee by the Holders of at least 33% in principal amount
      of the Outstanding Notes of such series, a written notice specifying such
      default or breach and requiring it to be remedied and stating that such
      notice is a "Notice of Default" hereunder, unless the Trustee, or the
      Trustee and the Holders of a principal amount of Notes of such series not
      less than the principal amount of Notes the Holders of which gave such
      notice, as the case may be, shall agree in writing to an extension of such
      period prior to its expiration; provided, however, that the Trustee, or
      the Trustee and the Holders of such principal amount of Notes of such
      series, as the case may be, shall be deemed to have agreed to an extension
      of such period for a maximum of one hundred twenty (120) days if
      corrective action is initiated by the Company within such period and is
      being diligently pursued; or

            (d) prior to the Release Date, a completed default (as defined in
      Section 66 of the First Mortgage) has occurred and is continuing;
      provided, however, that, anything in this Indenture to the contrary
      notwithstanding, the waiver or cure of such completed default under the
      First Mortgage and the rescission and annulment of the consequences
      thereof shall constitute a waiver of the corresponding Event of Default
      hereunder and a rescission and annulment of the consequences thereof;

            (e) the entry by a court having jurisdiction in the premises of (1)
      a decree or order for relief in respect of the Company in an involuntary
      case or proceeding under any applicable Federal or State bankruptcy,
      insolvency, reorganization or other similar law or (2) a decree or order
      adjudging the Company a bankrupt or insolvent, or approving as properly
      filed a petition by one or more Persons other than the Company seeking
      reorganization, arrangement, adjustment or composition of or in respect of
      the Company under any applicable Federal or State law, or appointing a
      custodian, receiver, liquidator, assignee, trustee, sequestrator or other
      similar official for the Company or for any


                                       46
<PAGE>

      substantial part of its property, or ordering the winding up or
      liquidation of its affairs, and any such decree or order for relief or any
      such other decree or order shall have remained unstayed and in effect for
      a period of 90 consecutive days; or

            (f) the commencement by the Company of a voluntary case or
      proceeding under any applicable Federal or State bankruptcy, insolvency,
      reorganization or other similar law or of any other case or proceeding to
      be adjudicated a bankrupt or insolvent, or the consent by it to the entry
      of a decree or order for relief in respect of the Company in case or
      proceeding under any applicable Federal or State bankruptcy, insolvency,
      reorganization or other similar law or to the commencement of any
      bankruptcy or insolvency case or proceeding against it, or the filing by
      it of a petition or answer or consent seeking reorganization or relief
      under any applicable Federal or State law, or the consent by it to the
      filing of such petition or to the appointment of or taking possession by a
      custodian, receiver, liquidator, assignee, trustee, sequestrator or
      similar official of the Company or of any substantial part of its
      property, or the making by it of an assignment for the benefit of
      creditors, or the admission by it in writing of its inability to pay its
      debts generally as they become due, or the authorization of such action by
      the Board of Directors; or

            (g) any other Event of Default specified with respect to Notes of
      such series.

Section 902. Acceleration of Maturity; Rescission and Annulment.

            If an Event of Default due to the default in payment of principal
of, or premium, if any, or interest on, any series of Notes or due to the
default in the performance or breach of any other covenant or warranty of the
Company applicable to the Notes of such series but not applicable to all
Outstanding Notes shall have occurred and be continuing, either the Trustee or
the Holders of not less than 33% in principal amount of the Notes of such series
may then declare the principal amount (or, if any of the Notes of such series
are Discount Notes, such portion of the principal amount as may be specified in
the terms thereof as contemplated by Section 301) of all Notes of such series
and premium, if payment of any thereof be in default, and interest accrued
thereon to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by the Holders). If an Event of Default due to
default in the performance of any other of the covenants or agreements herein
applicable to all Outstanding Notes or an Event of Default specified in Section
901(d), (e) or (f) shall have occurred and be continuing, either the Trustee or
the Holders of not less than 33% in principal amount of all Notes then
Outstanding (considered as one class), and not the Holders of the Notes of any
one of such series, may declare the principal amount (or, if any of the Notes
are Discount Notes, such portion of the principal amount of such Notes as may be
specified in the terms thereof as contemplated by Section 301) of all Notes and
premium, if payment of any thereof be in default, and interest accrued thereon
to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by the Holders). As a consequence of each such declaration
(herein referred to as a declaration of acceleration) with respect to Notes of
any series, the principal amount (or portion thereof in the case of Discount
Notes) of such Notes, any such premium, and interest accrued thereon shall
become due and payable immediately. Prior to the Release Date, upon all of the
Notes becoming immediately due and payable by declaration pursuant to any of the
foregoing provisions of this Section 902, the Trustee shall immediately file


                                       47
<PAGE>

with the Mortgage Trustee a written demand for the acceleration of the payment
of principal of and premium, if any and accrued interest on all Senior Note
First Mortgage Bonds pursuant to the applicable provisions of the First
Mortgage.

            At any time after such a declaration of acceleration with respect to
Notes of any series shall have been made and before a judgment or decree for
payment of the money due shall have been obtained by the Trustee as hereinafter
in this Article provided, and prior to the receipt by the Trustee from the
Mortgage Trustee of an irrevocable, valid and unconditional notice to the
Trustee of the acceleration of the payment of principal, by declaration or
otherwise, of all of the Senior Note First Mortgage Bonds issued and outstanding
under the First Mortgage, the Event or Events of Default and its consequences
(including, if given, the written demand for the acceleration of the payment of
principal of and premium, if any, and accrued interest on all such Senior Note
First Mortgage Bonds) giving rise to such declaration of acceleration shall,
without further act, be deemed to have been waived, and such declaration and its
consequences shall, without further act, be deemed to have been rescinded and
annulled, if

            (a) the Company shall have paid or deposited with the Trustee a sum
      sufficient to pay

                  (1) all overdue interest on all Notes of such series;

                  (2) the principal of and premium, if any, on any Notes of such
            series which have become due otherwise than by such declaration of
            acceleration and interest thereon at the rate or rates prescribed
            therefor in such Notes;

                  (3) to the extent that payment of such interest is lawful,
            interest upon overdue interest at the rate or rates prescribed
            therefor in such Notes;

                  (4) all amounts due to the Trustee under Section 1007;

            and

            (b) any other Event or Events of Default with respect to Notes of
      such series, other than the non-payment of the principal of Notes of such
      series which shall have become due solely by such declaration of
      acceleration, shall have been cured (including any completed default (as
      defined in Section 66 of the First Mortgage) under the First Mortgage, as
      evidenced by notice thereof received by the Trustee from the Mortgage
      Trustee) or waived as provided in Section 913 or under the First Mortgage.

No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereon.

Section 903. Collection of Indebtedness and Suits for Enforcement by Trustee.

            If an Event of Default described in clause (a) or (b) of Section 901
shall have occurred and be continuing, the Company shall, upon demand of the
Trustee, pay to it, for the benefit of the Holders of the Notes of the series
with respect to which such Event of Default shall


                                       48
<PAGE>

have occurred, the whole amount then due and payable on such Notes for principal
and premium, if any, and interest, if any, and, to the extent permitted by law,
interest on premium, if any, and on any overdue principal and interest, at the
rate or rates prescribed therefor in such Notes, and, in addition thereto, such
further amount as shall be sufficient to cover any amounts due to the Trustee
under Section 1007.

            If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Notes,
wherever situated.

            If an Event of Default with respect to Notes of any series shall
have occurred and be continuing, the Trustee may in its discretion proceed to
protect and enforce its rights (including, prior to the Release Date, any rights
the Trustee may have as a holder of Senior Note First Mortgage Bonds) and the
rights of the Holders of Notes of such series by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

Section 904. Trustee May File Proofs of Claim.

            In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Notes shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

            (a) to file and prove a claim for the whole amount of principal,
      premium, if any, and interest, if any, owing and unpaid in respect of the
      Notes and to file such other papers or documents as may be necessary or
      advisable in order to have the claims of the Trustee (including any claim
      for amounts due to the Trustee under Section 1007 and, prior to the
      Release Date, any claims of the Trustee as holder of Senior Note First
      Mortgage Bonds) and of the Holders allowed in such judicial proceeding,
      and

            (b) to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same,

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amounts due it under Section 1007.


                                       49
<PAGE>

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

Section 905. Trustee May Enforce Claims Without Possession of Notes.

            All rights of action and claims under this Indenture or the Notes
may be prosecuted and enforced by the Trustee without the possession of any of
the Notes or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders in respect of which such judgment has been recovered.

Section 906. Application of Money Collected.

            Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or premium, if
any, or interest, if any, upon presentation of the Notes in respect of which or
for the benefit of which such money shall have been collected and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  First: To the payment of all amounts due the Trustee under
            Section 1007;

                  Second: To the payment of the amounts then due and unpaid upon
            the Notes for principal of and premium, if any, and interest, if
            any, in respect of which or for the benefit of which such money has
            been collected, ratably, without preference or priority of any kind,
            according to the amounts due and payable on such Notes for
            principal, premium, if any, and interest, if any, respectively; and

                  Third: To the payment of the remainder, if any, to the
            Company, or to whomsoever may be lawfully entitled to receive the
            same or as a court of competent jurisdiction may direct.

Section 907. Limitation on Suits.

            No Holder shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

            (a) such Holder shall have previously given written notice to the
      Trustee of a continuing Event of Default with respect to the Notes of such
      series;

            (b) the Holders of not less than a majority in aggregate principal
      amount of the Outstanding Notes of all series in respect of which an Event
      of Default shall have occurred and be continuing, considered as one class,
      shall have made written request to


                                       50
<PAGE>

      the Trustee to institute proceedings in respect of such Event of Default
      in its own name as Trustee hereunder;

            (c) such Holder or Holders shall have offered to the Trustee
      reasonable indemnity against the costs, expenses and liabilities to be
      incurred in compliance with such request;

            (d) the Trustee for 60 days after its receipt of such notice,
      request and offer of indemnity shall have failed to institute any such
      proceeding; and

            (e) no direction inconsistent with such written request shall have
      been given to the Trustee during such 60-day period by the Holders of a
      majority in aggregate principal amount of the Outstanding Notes of all
      series in respect of which an Event of Default shall have occurred and be
      continuing, considered as one class;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

Section 908. Unconditional Right of Holders to Receive Principal, Premium and
             Interest.

            Notwithstanding any other provision in this Indenture, the Holder of
any Note shall have the right, which is absolute and unconditional, to receive
payment of the principal of and premium, if any, and (subject to Section 307)
interest, if any, on such Note on the Stated Maturity or Maturities expressed in
such Note (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

Section 909. Restoration of Rights and Remedies.

            If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding shall have
been discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee or to such Holder, then and in every such case, subject
to any determination in such proceeding, the Company, and Trustee and such
Holder shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and such Holder
shall continue as though no such proceeding had been instituted.

Section 910. Rights and Remedies Cumulative.

            Except as otherwise provided in the last paragraph of Section 306,
no right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or


                                       51
<PAGE>

hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 911. Delay or Omission Not Waiver.

            No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 912. Control by Holders of Notes.

            If an Event of Default shall have occurred and be continuing in
respect of a series of Notes, the Holders of a majority in principal amount of
the Outstanding Notes of such series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, with respect
to the Notes of such series; provided, however, that if an Event of Default
shall have occurred and be continuing with respect to more than one series of
Notes, the Holders of a majority in aggregate principal amount of the
Outstanding Notes of all such series, considered as one class, shall have the
right to make such direction, and not the Holders of the Notes of any one of
such series; and provided, further, that

            (a) such direction shall not be in conflict with any rule of law or
      with this Indenture, and could not involve the Trustee in personal
      liability in circumstances where indemnity would not in the Trustee's
      reasonable discretion be adequate, and

            (b) the Trustee may take any other action deemed proper by the
      Trustee that is not inconsistent with such direction.

            Before proceeding to exercise any right or power hereunder at the
direction of such Holders, the Trustee shall be entitled to receive from such
Holders reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in compliance with any such direction.

Section 913. Waiver of Past Defaults.

            The Holders of not less than a majority in aggregate principal
amount of the Outstanding Notes of any series may on behalf of the Holders of
all the Notes of such series waive any past default hereunder with respect to
such series and its consequences, except a default

            (a) in the payment of the principal of or premium, if any, or
      interest, if any, on any Note of such series, or


                                       52
<PAGE>

            (b) in respect of a covenant or provision hereof which under Section
      1302 cannot be modified or amended without the consent of the Holder of
      each Outstanding Note of such series affected.

            Upon any such waiver, such default shall cease to exist, and any and
all Events of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

Section 914. Undertaking for Costs.

            The Company and the Trustee agree, and each Holder by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in aggregate
principal amount of the Outstanding Notes of all series in respect of which such
suit may be brought, considered as one class, or to any suit instituted by any
Holder for the enforcement of the payment of the principal of or premium, if
any, or interest, if any, on any Note on or after the Stated Maturity or
Maturities expressed in such Note (or, in the case of redemption, on or after
the Redemption Date).

Section 915. Waiver of Stay or Extension Laws.

            The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

Section 916. Default Under the First Mortgage.

            In addition to every other right and remedy provided herein, the
Trustee may exercise any right or remedy available to the Trustee in its
capacity as owner and holder of Senior Note First Mortgage Bonds which arises as
a result of a completed default (as defined in Section 66 of the First Mortgage)
whether or not an Event of Default hereunder shall then have occurred and be
continuing.

Section 1001. Certain Duties and Responsibilities.

            (a) The Trustee shall have and be subject to all the duties and
      responsibilities specified with respect to an indenture trustee in the
      Trust Indenture Act and no implied covenants or obligations shall be read
      into this Indenture against the Trustee. For purposes of Sections 315(a)
      and 315(c) of the Trust Indenture Act, the term "default" is hereby
      defined as an Event of Default which has occurred and is continuing.

            (b) No provision of this Indenture shall require the Trustee to
      expend or risk its own funds or otherwise incur any financial liability in
      the performance of any of its duties hereunder, or in the exercise of any
      of its rights or powers, if it shall have reasonable grounds for believing
      that repayment of such funds or adequate indemnity against such risk or
      liability is not reasonably assured to it.

            (c) Notwithstanding anything contained in this Indenture to the
      contrary, the duties and responsibilities of the Trustee under this
      Indenture shall be subject to the protections, exculpations and
      limitations on liability afforded to the Trustee under the provisions of
      the Trust Indenture Act, including those provisions of such Act deemed by
      such Act to be included herein. For the purpose of Section 315(d)(2) of
      the Trust Indenture Act, the term "responsible officer" is hereby defined
      as a Responsible Officer and the chairman or vice-chairman of the board of
      directors, the chairman or vice-chairman of the executive committee of the
      board of directors, the president, any vice president, the secretary, any
      assistant secretary, the treasurer, any assistant treasurer, the cashier,

      performed by a Responsible Officer or any of the above designated officers
      and also means, with respect to a particular corporate trust matter, any
      other officer to whom such matter is referred because of his or her
      knowledge of or familiarity with the particular subject.

            (d) Whether or not therein expressly so provided, every provision of
      this Indenture relating to the conduct or affecting the liability of or
      affording protection to the Trustee shall be subject to the provisions of
      this Section.

Section 1002. Notice of Defaults.

            The Trustee shall give the Holders notice of any default hereunder
with respect to the Notes of any series to the Holders of Notes of such series
of which it has knowledge (within the meaning of Section 1003(h) hereof) in the
manner and to the extent required to do so by the Trust Indenture Act, unless
such default shall have been cured or waived; provided, however, that in the
case of any default of the character specified in Section 901(c), no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
For the purpose of this


                                       54
<PAGE>

Section, the term "default" means any event that is, or after notice or lapse of
time, or both, would become, an Event of Default.

Section 1003. Certain Rights of Trustee.

            (c) whenever in the administration of this Indenture the Trustee
      shall deem it desirable that a matter be proved or established prior to
      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officer's Certificate,

      the costs, expenses and liabilities which might be incurred by it in
      compliance with such request or direction;

            (f) the Trustee shall not be bound to make any investigation into

      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall (subject to applicable legal requirements) be
      entitled to examine, during normal business hours, the books, records and
      premises of the Company, personally or by agent or attorney;

            (g) the Trustee may execute any of the trusts or powers hereunder or

      or Event of Default with respect to the Notes of any series for which it
      is acting as Trustee unless either (1) a Responsible Officer of the
      Trustee shall have actual knowledge of the default or Event of Default or
      (2) written notice of such default or Event of Default (which shall state
      that such notice is a "Notice of Default" or a "Notice of an Event of
      Default" hereunder, as the case may be) shall have been given to the
      Trustee by the Company, any other obligor on such Notes or by any Holder
      of such Notes, or in the case of an Event of Default described in Section
      901(d), by the Mortgage Trustee or Holders of at least 25% in principal
      amount of the outstanding Notes.

Section 1004. Not Responsible for Recitals or Issuance of Notes.

            The recitals contained herein and in the Notes (except the Trustee's
certificates of authentication) shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes or as to the value, title or
validity of any Senior Note First Mortgage Bonds or other securities at any time
pledged or deposited with the Trustee hereunder or as to the security offered
thereby or hereby. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of Notes or the proceeds
thereof.

Section 1005. May Hold Notes.

            Each of the Trustee, any Authenticating Agent, any Paying Agent, any
Note Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Notes and, subject to Sections 1008
and 1013, may otherwise deal with the Company with the same rights it would have
if it were not the Trustee, Authenticating Agent, Paying Agent, Note Registrar
or such other agent.

Section 1006. Money Held in Trust.

hereunder except as expressly provided herein or otherwise agreed with, and for
the sole benefit of, the Company.

Section 1007. Compensation and Reimbursement.

            The Company shall

            (a) pay to the Trustee from time to time reasonable compensation for
      all services rendered by it hereunder (which compensation shall not be
      limited by any provision of law in regard to the compensation of a trustee
      of an express trust);

            (b) except as otherwise expressly provided herein, reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances reasonably incurred or made by the Trustee in accordance with any
      provision of this Indenture, including the


                                       56
<PAGE>

      costs of collection and (including the reasonable compensation and the
      expenses and disbursements of its agents and counsel), except to the
      extent that any such expense, disbursement or advance may be attributable
      to its negligence, willful misconduct or bad faith; and

            (c) indemnify the Trustee and hold it harmless from and against any
      loss, liability or expense (including reasonable attorney's fees and
      expenses) incurred without negligence or bad faith on its part arising out
      of or in connection with the acceptance or administration of the trust or
      trusts hereunder or the performance of its duties hereunder, including the
      costs and expenses of defending itself against any claim or liability in
      connection with the exercise or performance of any of its powers or duties
      hereunder.

            As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Notes upon all
property and funds held or collected by the Trustee as such other than property
and funds held in trust under Section 803 (except as otherwise provided in
Section 803). "Trustee" for purposes of this Section shall include any
predecessor Trustee; provided; however, that the negligence, willful misconduct
or bad faith of any Trustee hereunder shall not affect the rights of any other
Trustee hereunder.

            When a Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 901(e) or Section 901(f), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

            The provisions of this Section 1007 shall survive termination of
this Indenture.

Section 1008. Disqualification; Conflicting Interests.

            If the Trustee shall have or acquire any conflicting interest within
the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the effect,
and subject to the conditions, provided in the Trust Indenture Act and this
Indenture. For purposes of Section 310(b)(1) of the Trust Indenture Act and to
the extent permitted thereby, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a Trustee under (i) this Indenture with
respect to Notes of more than one series, or (ii) the First Mortgage or with
respect to the Senior Note First Mortgage Bonds issued thereunder.

            There shall at all times be a Trustee hereunder which shall be

            (a) a corporation organized and doing business under the laws of the
      United States, any State or Territory thereof or the District of Columbia,
      authorized under such laws to exercise corporate trust powers, having a
      combined capital and surplus of at least $100,000,000 and subject to
      supervision or examination by Federal or State authority, or


                                       57
<PAGE>

            (b) if and to the extent permitted by the Commission by rule,
      regulation or order upon application, a corporation or other Person
      organized and doing business under the laws of a foreign government,
      authorized under such laws to exercise corporate trust powers, having a
      combined capital and surplus of at least $100,000,000 or the Dollar
      equivalent of the applicable foreign currency and subject to supervision

      subdivision thereof substantially equivalent to supervision or examination
      applicable to United States institutional trustees,

and, in either case, qualified and eligible under this Article and the Trust
Indenture Act. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of such supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

Section 1010. Resignation and Removal; Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
      successor Trustee pursuant to this Article shall become effective until
      the acceptance of appointment by the successor Trustee in accordance with
      the applicable requirements of Section 1011.

            (b) The Trustee may resign at any time with respect to the Notes of
      one or more series by giving written notice thereof to the Company. If the
      instrument of acceptance by a successor Trustee required by Section 1011
      shall not have been delivered to the Trustee within 30 days after the
      giving of such notice of resignation, the resigning Trustee may petition
      any court of competent jurisdiction for the appointment of a successor
      Trustee with respect to the Notes of such series.

            (c) The Trustee may be removed at any time with respect to the Notes
      of any series by Act of the Holders of a majority in principal amount of
      the Outstanding Notes of such series delivered to the Trustee and to the
      Company.

            (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 1008 after
            written request therefor by the Company or by any Holder who has
            been a bona fide Holder for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 1009
            and shall fail to resign after written request therefor by the
            Company or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
            adjudged a bankrupt or insolvent or a receiver of the Trustee or of
            its property shall be appointed or any public officer shall take
            charge or control of the Trustee or of its property or affairs for
            the purpose of rehabilitation, conservation or liquidation,


                                       58
<PAGE>

      then, in any such case, (x) the Company by a Board Resolution may remove
      the Trustee with respect to all Notes or (y) subject to Section 914, any
      Holder who has been a bona fide Holder for at least six months may, on
      behalf of himself and all others similarly situated, petition any court of
      competent jurisdiction for the removal of the Trustee with respect to all
      Notes and the appointment of a successor Trustee or Trustees.

            (e) If the Trustee shall resign, be removed or become incapable of
      acting, or if a vacancy shall occur in the office of Trustee for any cause
      (other than as contemplated in clause (y) in subsection (d) of this
      Section), with respect to the Notes of one or more series, the Company, by
      a Board Resolution, shall promptly appoint a successor Trustee or Trustees
      with respect to the Notes of that or those series (it being understood
      that any such successor Trustee may be appointed with respect to the Notes
      of one or more or all of such series and that at any time there shall be
      only one Trustee with respect to the Notes of any particular series) and
      shall comply with the applicable requirements of Section 1011. If, within
      one year after such resignation, removal or incapability, or the
      occurrence of such vacancy, a successor Trustee with respect to the Notes
      of any series shall be appointed by Act of the Holders of a majority in
      principal amount of the Outstanding Notes of such series delivered to the
      Company and the retiring Trustee, the successor Trustee so appointed
      shall, forthwith upon its acceptance of such appointment in accordance
      with the applicable requirements of Section 1011, become the successor
      Trustee with respect to the Notes of such series and to that extent
      supersede the successor Trustee appointed by the Company. If no successor
      Trustee with respect to the Notes of any series shall have been so
      appointed by the Company or the Holders and accepted appointment in the
      manner required by Section 1011, any Holder who has been a bona fide
      Holder of a Note of such series for at least six months may, on behalf of
      itself and all others similarly situated, petition any court of competent
      jurisdiction for the appointment of a successor Trustee with respect to
      the Notes of such series.

            (f) So long as no event which is, or after notice or lapse of time,
      or both, would become, an Event of Default shall have occurred and be
      continuing, and except with respect to a Trustee appointed by Act of the
      Holders of a majority in principal amount of the Outstanding Notes
      pursuant to subsection (e) of this Section, if the Company shall have
      delivered to the Trustee (i) a Board Resolution appointing a successor
      Trustee, effective as of a date specified therein, and (ii) an instrument
      of acceptance of such appointment, effective as of such date, by such
      successor Trustee in accordance with Section 1011, the Trustee shall be
      deemed to have resigned as contemplated in subsection (b) of this Section,
      the successor Trustee shall be deemed to have been appointed by the
      Company pursuant to subsection (e) of this Section and such appointment
      shall be deemed to have been accepted as contemplated in Section 1011, all
      as of such date, and all other provisions of this Section and Section 1011
      shall be applicable to such resignation, appointment and acceptance except
      to the extent inconsistent with this subsection (f).

            (g) The Company or, should the Company fail so to act promptly, the
      successor Trustee at the expense of the Company shall give notice of each
      resignation and each removal of the Trustee with respect to the Notes of

      Holders of Notes of such series as their names and addresses appear in the
      Note Register. Each notice shall include the name of the successor Trustee
      with respect to the Notes of such series and the address of its corporate
      trust office.

Section 1011. Acceptance of Appointment by Successor.

            (a) In case of the appointment hereunder of a successor Trustee with
      respect to the Notes of all series, every such successor Trustee so
      appointed shall execute, acknowledge and deliver to the Company and to the
      retiring Trustee an instrument accepting such appointment, and thereupon
      the resignation or removal of the retiring Trustee shall become effective
      and such successor Trustee, without any further act, deed or conveyance,
      shall become vested with all the rights, powers, trusts and duties of the
      retiring Trustee, including rights, title and interest in the Senior Note
      First Mortgage Bonds; but, on the request of the Company or the successor
      Trustee, such retiring Trustee shall, upon payment of all sums owed to it,
      execute and deliver an instrument transferring to such successor Trustee
      all the rights, powers and trusts of the retiring Trustee and shall duly
      assign, transfer and deliver to such successor Trustee all property and
      money held by such retiring Trustee hereunder.

            (b) In case of the appointment hereunder of a successor Trustee with
      respect to the Notes of one or more (but not all) series, the Company, the
      retiring Trustee and each successor Trustee with respect to the Notes of
      one or more series shall execute and deliver an indenture supplemental
      hereto wherein each successor Trustee shall accept such appointment and
      which (1) shall contain such provisions as shall be necessary or desirable
      to transfer and confirm to, and to vest in, each successor Trustee all the
      rights, powers and trusts of the retiring Trustee with respect to the
      Notes of that or those series to which the appointment of such successor
      Trustee relates, (2) if the retiring Trustee is not retiring with respect
      to all Notes, shall contain such provisions as shall be deemed necessary
      or desirable to confirm that all the rights, powers, trusts and duties of
      the retiring Trustee with respect to the Notes of that or those series as
      to which the retiring Trustee is not retiring shall continue to be vested
      in the retiring Trustee and (3) shall add to or change any of the
      provisions of this Indenture as shall be necessary to provide for or
      facilitate the administration of the trusts hereunder by more than one
      Trustee, it being understood that nothing herein or in such supplemental
      indenture shall constitute such Trustees co-trustees of the same trust and
      that each such Trustee shall be trustee of a trust or trusts hereunder
      separate and apart from any trust or trusts hereunder administered by any
      other such Trustee; and upon the execution and delivery of such
      supplemental indenture the resignation or removal of the retiring Trustee
      shall become effective to the extent provided therein and each such
      successor Trustee, without any further act, deed or conveyance, shall
      become vested with all the rights, powers, trusts and duties of the
      retiring Trustee with respect to the Notes of that or those series to
      which the appointment of such successor Trustee relates; but, on request
      of the Company or any successor Trustee, such retiring Trustee, upon
      payment of all sums owed to it, shall duly assign, transfer and deliver to
      such successor Trustee all property and money held by such retiring
      Trustee hereunder with respect to the Notes of that or those series to
      which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
      execute any instruments which fully vest in and confirm to such successor
      Trustee all such rights, powers and trusts referred to in subsection (a)
      or (b) of this Section, as the case may be.

            (d) No successor Trustee shall accept its appointment unless at the
      time of such acceptance such successor Trustee shall be qualified and
      eligible under this Article.

Section 1012. Merger, Conversion, Consolidation or Succession to Business.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

Section 1013. Preferential Collection of Claims Against Company.

            If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Notes (other than by reason of a relationship described
in Section 311(b) of the Trust Indenture Act), the Trustee shall be subject to
any and all applicable provisions of the Trust Indenture Act regarding the
collection of claims against the Company or such other obligor. For purposes of
Section 311(b) of the Trust Indenture Act:

            (a) the term "cash transaction" means any transaction in which full
      payment for goods or Notes sold is made within seven days after delivery
      of the goods or Notes in currency or in checks or other orders drawn upon
      banks or bankers and payable upon demand;

            (b) the term "self-liquidating paper" means any draft, bill of
      exchange, acceptance or obligation which is made, drawn, negotiated or
      incurred by the Company for the purpose of financing the purchase,
      processing, manufacturing, shipment, storage or sale of goods, wares or
      merchandise and which is secured by documents evidencing title to,
      possession of, or a lien upon, the goods, wares or merchandise or the
      receivables or proceeds arising from the sale of the goods, wares or
      merchandise previously constituting the security, provided the security is
      received by the Trustee simultaneously with the creation of the creditor
      relationship with the Company arising from the making, drawing,
      negotiating or incurring of the draft, bill of exchange, acceptance or
      obligation.

Section 1014. Co-trustees and Separate Trustees.

            At any time or times, for the purpose of meeting the legal
requirements of any applicable jurisdiction, the Company and the Trustee shall
have power to appoint, and, upon the


                                       61
<PAGE>

written request of the Trustee or of the Holders of at least thirty-three
percent (33%) in principal amount of the Notes then Outstanding, the Company
shall for such purpose join with the Trustee in the execution and delivery of
all instruments and agreements necessary or proper to appoint, one or more
Persons approved by the Trustee either to act as co-trustee, jointly with the
Trustee, or to act as separate trustee, in either case with such powers as may
be provided in the instrument of appointment, and to vest in such Person or
Persons, in the capacity aforesaid, any property, title, right or power deemed
necessary or desirable, subject to the other provisions of this Section. If the
Company does not join in such appointment within 15 days after the receipt by it
of a request so to do, or if an Event of Default shall have occurred and be
continuing, the Trustee alone shall have power to make such appointment.

            Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed, acknowledged
and delivered by the Company.

            Every co-trustee or separate trustee shall, to the extent permitted
by law, but to such extent only, be appointed subject to the following
conditions:

            (a) the Notes shall be authenticated and delivered, and all rights,
      powers, duties and obligations hereunder in respect of the custody of
      Notes, cash and other personal property held by, or required to be
      deposited or pledged with, the Trustee hereunder, shall be exercised
      solely, by the Trustee;

            (b) the rights, powers, duties and obligations hereby conferred or
      imposed upon the Trustee in respect of any property covered by such
      appointment shall be conferred or imposed upon and exercised or performed
      either by the Trustee or by the Trustee and such co-trustee or separate
      trustee jointly, as shall be provided in the instrument appointing such
      co-trustee or separate trustee, except to the extent that under any law of
      any jurisdiction in which any particular act is to be performed, the
      Trustee shall be incompetent or unqualified to perform such act, in which
      event such rights, powers, duties and obligations shall be exercised and
      performed by such co-trustee or separate trustee;

            (c) the Trustee at any time, by an instrument in writing executed by
      it, with the concurrence of the Company, may accept the resignation of or
      remove any co-trustee or separate trustee appointed under this Section,
      and, if an Event of Default shall have occurred and be continuing, the
      Trustee shall have power to accept the resignation of, or remove, any such
      co-trustee or separate trustee without the concurrence of the Company.
      Upon the written request of the Trustee, the Company shall join with the
      Trustee in the execution and delivery of all instruments and agreements
      necessary or proper to effectuate such resignation or removal. A successor
      to any co-trustee or separate trustee so resigned or removed may be
      appointed in the manner provided in this Section;

            (d) no co-trustee or separate trustee hereunder shall be personally
      liable by reason of any act or omission of the Trustee, or any other such
      trustee hereunder; and


                                       62
<PAGE>

            (e) any Act of Holders delivered to the Trustee shall be deemed to
      have been delivered to each such co-trustee and separate trustee.

Section 1015. Appointment of Authenticating Agent.

            The Trustee may appoint an Authenticating Agent or Agents with
respect to the Notes of one or more series, or any Tranche thereof, which shall
be authorized to act on behalf of the Trustee to authenticate Notes of such
series or Tranche issued upon original issuance, exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and Notes so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Notes by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States, any State or territory thereof or the District of Columbia or the
Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

            Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

            An Authenticating Agent may resign at any time by giving 45 days
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder, with like effect as
if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.


                                       63
<PAGE>

            The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

            The provisions of Sections 308, 1004 and 1005 shall be applicable to
each Authenticating Agent.

            If an appointment with respect to the Notes of one or more series,
or any Tranche thereof, shall be made pursuant to this Section, the Notes of
such series or Tranche may have endorsed thereon, in addition to the Trustee's
certificate of authentication, an alternate certificate of authentication
substantially in the following form:

            This is one of the Notes of the series designated therein referred
to in the within-mentioned Indenture.

Dated:


                                        ________________________________________
                                                       As Trustee


                                        By______________________________________
                                                 As Authenticating Agent


                                        By______________________________________
                                                  Authorized Signatory

            If all of the Notes of a series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating Notes
upon original issuance located in a Place of Payment where the Company wishes to
have Notes of such series authenticated upon original issuance, the Trustee, if
so requested by the Company in writing (which writing need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel), shall
appoint, in accordance with this Section and in accordance with such procedures
as shall be acceptable to the Trustee, an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Notes.

and October 1 in each year, commencing with the year 1999, and at such other

list need be furnished so long as the Trustee shall be the Note Registrar. Every
holder of Notes by receiving and holding the same, agrees with the Company and
the Trustee that neither the Company nor the Trustee nor any agent of either of
them shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders of Notes in accordance

any successor section of such Act.

manner, as shall be required by the Trust Indenture Act. The Company shall
notify the Trustee of the listing of any Notes on any securities exchange.
Delivery of such reports, information and documents by the Company to the
Trustee is for informational purposes only, and the Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

into which the Company is merged or the Person to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may

            provisions, or shall by operation of law be deemed to effect such
            changes or incorporate such provisions by reference or otherwise,
            this Indenture shall be deemed to have been amended so as to conform
            to such amendment to the Trust Indenture Act, and the Company and
            the Trustee may, without the consent of any Holders, enter into an
            indenture supplemental hereto to effect or evidence such changes or
            additional provisions; or

                  (y) if any such amendment shall permit one or more changes to,
            or the elimination of, any provisions hereof which, at the date of
            the execution and delivery hereof or at any time thereafter, are
            required by the Trust Indenture Act to be contained herein, this
            Indenture shall be deemed to have been amended to effect such
            changes or elimination, and the Company and the Trustee may, without
            the consent of any Holders, enter into an indenture or indentures
            supplemental hereto to evidence such amendment hereof.

Section 1302. Supplemental Indentures With Consent of Holders.

            With the consent of the Holders of not less than a majority in
aggregate principal amount of the Notes of all series then Outstanding under
this Indenture, considered as one class, by Act of said Holders delivered to the
Company and the Trustee, the Company, when authorized by a Board Resolution, and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to, or changing in any manner or
eliminating any of the provisions of, this Indenture; provided, however, that if
there shall be Notes of more than one series Outstanding hereunder and if a
proposed supplemental indenture shall directly affect the rights of the Holders
of Notes of one or more, but less than all, of such series, then the consent
only of the Holders of a majority in aggregate principal amount of the
Outstanding Notes of all series so directly affected, considered as one class,
shall be required; and provided, further, that if the Notes of any series shall
have been issued in more than one


                                       68
<PAGE>

Tranche and if the proposed supplemental indenture shall directly affect the
rights of the Holders of Notes of one or more, but less than all, of such
Tranches, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Notes of all Tranches so directly affected,
considered as one class, shall be required; and provided, further, that no such
supplemental indenture shall:

            (a) change the Stated Maturity of the principal of, or any
      installment of principal of or interest on, any Note, or reduce the
      principal amount thereof or the rate of interest thereon (or the amount of
      any installment of interest thereon) or change the method of calculating
      such rate, or reduce any premium payable upon the redemption thereof, or
      reduce the amount of the principal of a Discount Note that would be due
      and payable upon a declaration of acceleration of the Maturity thereof
      pursuant to Section 902, or change the coin or currency (or other
      property) in which any Note or any premium or the interest thereon is
      payable, or impair the right to institute suit for the enforcement of any
      such payment on or after the Stated Maturity of any Note (or, in the case
      of redemption, on or after the Redemption Date), without, in any such
      case, the consent of the Holder of such Note, or

            (b) prior to the Release Date, impair the interest hereunder of the
      Trustee in any Senior Note First Mortgage Bonds, reduce the principal
      amount of any series of Senior Note First Mortgage Bonds to an amount less
      than the principal amount of the related series of Notes or alter the
      payment provisions of such Senior Note First Mortgage Bonds in a manner
      adverse to the Holders of the Senior Notes, without, in any such case, the
      consent of the Holder of each Outstanding Note; or

            (c) reduce the percentage in principal amount of the Outstanding
      Notes of any series or any Tranche thereof, the consent of the Holders of
      which is required for any such supplemental indenture, or the consent of

            (d) modify any of the provisions of this Section, Section 707 or
      Section 913 with respect to the Notes of any series, or any Tranche
      thereof (except to increase the percentages in principal amount referred
      to in this Section or such other Sections or to provide that other
      provisions of this Indenture cannot be modified or waived) without the
      consent of the Holder of each Outstanding Note affected thereby; provided,
      however, that this clause shall not be deemed to require the consent of
      any Holder with respect to changes in the references to "the Trustee" and
      concomitant changes in this Section, or the deletion of this proviso, in
      accordance with the requirements of Sections 1011(b), 1014 and 1301(h).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Notes, or of one or more Tranches
thereof, or which modifies the rights of the Holders of Notes of such series or
Tranches with respect to such covenant or other provision, shall be


                                       69
<PAGE>

deemed not to affect the rights under this Indenture of the Holders of Notes of
any other series or Tranche.

It shall not be necessary for any Act of Holders under this Section to approve
the particular form of any proposed supplemental indenture, but it shall be
sufficient if such Act shall approve the substance thereof. A waiver by a Holder
of such Holder's right to consent under this Section shall be deemed to be a
consent of such Holder.

Section 1303. Execution of Supplemental Indentures.

            In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 1001) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties, immunities or liabilities under this Indenture or
otherwise.

Section 1304. Effect of Supplemental Indentures.

            Upon the execution of any supplemental indenture under this Article
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Notes theretofore or thereafter authenticated and delivered hereunder shall
be bound thereby. Any supplemental indenture permitted by this Article may
restate this Indenture in its entirety, and, upon the execution and delivery
thereof, any such restatement shall supersede this Indenture as theretofore in
effect for all purposes.

Section 1305. Conformity with Trust Indenture Act.

            Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

Section 1306. Reference in Notes to Supplemental Indentures.

            Notes of any series, or any Tranche thereof, authenticated and
delivered after the execution of any supplemental indenture pursuant to this
Article may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Notes of any series, or any
Tranche thereof, so modified as to conform, in the opinion of the Trustee and
the Company, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for
Outstanding Notes of such series or Tranche.

Section 1307. Modification Without Supplemental Indenture.

            If the terms of any particular series of Notes shall have been
established in a Board Resolution or an Officer's Certificate pursuant to a
Board Resolution as contemplated by Section 301, and not in an indenture
supplemental hereto, additions to, changes in or the elimination of any of such
terms may be effected by means of a supplemental Board Resolution or Officer's
Certificate, as the case may be, delivered to, and accepted by, the Trustee;
provided, however, that such supplemental Board Resolution or Officer's
Certificate shall not be accepted by the Trustee or otherwise be effective
unless all conditions set forth in this Indenture which would be required to be
satisfied if such additions, changes or elimination were contained in a
supplemental indenture shall have been appropriately satisfied. Upon the
acceptance thereof by the Trustee, any such supplemental Board Resolution or
Officer's Certificate shall be deemed to be a "supplemental indenture" for
purposes of Section 1304 and 1306.

                                   ARTICLE XIV

                   Meetings of Holders; Action Without Meeting

Section 1401. Purposes for Which Meetings May Be Called.

            A meeting of Holders of Notes of one or more, or all, series, or any

      meeting, shall be given, in the manner provided in Section 106, not less
      than 21 nor more than 180 days prior to the date fixed for the meeting.

            (b) If the Trustee shall have been requested to call a meeting of

      Tranches thereof, by the Company or by the Holders of 33% in aggregate
      principal amount of all of such series and Tranches, considered as one
      class, for any purpose specified in Section 1401, by written request
      setting forth in reasonable detail the action proposed to be taken at the
      meeting, and the Trustee shall not have given the notice of such meeting
      within 21 days after receipt of such request or shall not thereafter
      proceed to cause the meeting to be held as provided herein, then the
      Company or the Holders of Notes of such series and Tranches in the amount
      above specified, as the case may be, may determine the time and the place


                                       71

            (c) Any meeting of Holders of Notes of one or more, or all, series,
      or any Tranche or Tranches thereof, shall be valid without notice if the
      Holders of all Outstanding Notes of such series or Tranches are present in
      person or by proxy and if representatives of the Company and the Trustee
      are present, or if notice is waived in writing before or after the meeting
      by the Holders of all Outstanding Notes of such series, or by such of them
      as are not present at the meeting in person or by proxy, and by the
      Company and the Trustee.

Section 1404. Quorum; Action.

            The Persons entitled to vote a majority in aggregate principal
amount of the Outstanding Notes of the series and Tranches with respect to which
a meeting shall have been called as hereinbefore provided, considered as one
class, shall constitute a quorum for a meeting of Holders of Notes of such
series and Tranches; provided, however, that if any action is to be taken at
such meeting which this Indenture expressly provides may be taken by the Holders
of a specified percentage, which is less than a majority, in principal amount of
the Outstanding Notes of such series and Tranches, considered as one class, the
Persons entitled to vote such specified percentage in principal amount of the
Outstanding Notes of such series and Tranches, considered as one class, shall
constitute a quorum. In the absence of a quorum within one hour of the time
appointed for any such meeting, the meeting shall, if convened at the request of
Holders of Notes of such series and Tranches, be dissolved. In any other case
the meeting may be adjourned for such period as may be determined by the

<PAGE>

            Except as limited by Section 1302, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in aggregate principal amount of the Outstanding Notes of the series
and Tranches with respect to which such meeting shall have been called,
considered as one class; provided, however, that, except as so limited, any
resolution with respect to any action which this Indenture expressly provides
may be taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Notes of such series and
Tranches, considered as one class, may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Notes of such series and Tranches, considered as one class.

            Any resolution passed or decision taken at any meeting of Holders of
Notes duly held in accordance with this Section shall be binding on all the
Holders of Notes of the series and Tranches with respect to which such meeting
shall have been held, whether or not present or represented at the meeting.

Section 1405. Attendance at Meetings; Determination of Voting Rights; Conduct
              and Adjournment of Meetings.

            (a) Attendance at meetings of Holders of Notes may be in person or
      by proxy; and, to the extent permitted by law, any such proxy shall remain
      in effect and be binding upon any future Holder of the Notes with respect
      to which it was given unless and until specifically revoked by the Holder
      or future Holder of such Notes before being voted.

            (b) Notwithstanding any other provisions of this Indenture, the
      Trustee may make such reasonable regulations as it may deem advisable for
      any meeting of Holders of Notes in regard to proof of the holding of such
      Notes and of the appointment of proxies and in regard to the appointment
      and duties of inspectors of votes, the submission and examination of
      proxies, certificates and other evidence of the right to vote, and such
      other matters concerning the conduct of the meeting as it shall deem
      appropriate. Except as otherwise permitted or required by any such
      regulations, the holding of Notes shall be proved in the manner specified
      in Section 104 and the appointment of any proxy shall be proved in the
      manner specified in Section 104. Such regulations may provide that written
      instruments appointing proxies, regular on their face, may be presumed
      valid and genuine without the proof specified in Section 104 or other
      proof.

            (c) The Trustee shall, by an instrument in writing, appoint a
      temporary chairman of the meeting, unless the meeting shall have been
      called by the Company or by Holders as provided in Section 1402(b), in
      which case the Company or the Holders of Notes of the series and Tranches
      calling the meeting, as the case may be, shall in like manner appoint a
      temporary chairman. A permanent chairman and a permanent secretary of the
      meeting shall be elected by vote of the Persons entitled to vote a
      majority in aggregate principal amount of the Outstanding Notes of all
      series and Tranches represented at the meeting, considered as one class.


                                       73
<PAGE>

            (d) At any meeting each Holder or proxy shall be entitled to one
      vote for each $1 principal amount of Notes held or represented by him;
      provided, however, that no vote shall be cast or counted at any meeting in
      respect of any Note challenged as not Outstanding and ruled by the
      chairman of the meeting to be not Outstanding. The chairman of the meeting
      shall have no right to vote, except as a Holder of a Note or proxy.

            (e) Any meeting duly called pursuant to Section 1402 at which a
      quorum is present may be adjourned from time to time by Persons entitled
      to vote a majority in aggregate principal amount of the Outstanding Notes
      of all series and Tranches represented at the meeting, considered as one
      class; and the meeting may be held as so adjourned without further notice.

Section 1406. Counting Votes and Recording Action of Meetings.

            The vote upon any resolution submitted to any meeting of Holders
shall be by written ballots on which shall be subscribed the signatures of the
Holders or of their representatives by proxy and the principal amounts and
serial numbers of the Outstanding Notes, of the series and Tranches with respect
to which the meeting shall have been called, held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports of all votes cast at the meeting. A record of the proceedings of each
meeting of Holders shall be prepared by the secretary of the meeting and there
shall be attached to said record the original reports of the inspectors of votes
on any vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

Section 1407. Action Without Meeting.

            In lieu of a vote of Holders at a meeting as hereinbefore
contemplated in this Article, any request, demand, authorization, direction,
notice, consent, waiver or other action may be made, given or taken by Holders
by written instruments as provided in Section 104.

         Immunity of Incorporators, Stockholders, Officers and Directors

Section 1501. Liability Solely Corporate.

            No recourse shall be had for the payment of the principal of or
premium, if any, or interest, if any, on any Notes, 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


                                       74

agreement under this Indenture, against any incorporator, stockholder, officer
or director, as such, past, present or future of the Company or of any

provision, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise, it being expressly agreed and understood that this
Indenture and all the Notes are solely corporate obligations, and that no
personal liability whatsoever shall attach to, or be incurred by, any

indirectly through the Company or any predecessor or successor corporation,
because of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants or agreements contained in this Indenture or in any
of the Notes or to be implied herefrom or therefrom, and that any such personal
liability is hereby expressly waived and released as a condition of, and as part
of the consideration for, the execution of this Indenture and the issuance of
the Notes.

      Southern Indiana Gas & Electric, a corporation duly organized and existing

the principal sum of _______________ Dollars ($_____) on

<PAGE>

________, 20__, and to pay interest thereon from ________, 1999 or from the most
recent Interest Payment Date with respect to which interest has been paid or
duly provided for, semi-annually on ________ 1 and ________ 1 in each year (each
an "Interest Payment Date"), commencing ________, ____, at the rate of ___% per
annum, until the principal hereof is paid or made available for payment,
provided that any principal and premium, and any such installment of interest,
which is overdue shall bear interest at the rate of ____% per annum (to the
extent that the payment of such interest shall be legally enforceable); from the
dates such amounts are due until they are paid or made available for payment,
and such interest shall be payable on demand. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Note (or
one or more Predecessor Notes) is registered at the close of business on the
Regular Record Date for such interest, which shall be the ________ 15 or
________ 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Note (or one
or more Predecessor Notes) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Notes of this series not
less than 10 days prior to such Special Record Date, or be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Notes of this series may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in said
Indenture.

      Payment of the principal of (and premium if any) and such interest on this
Note will be made at the office or agency of the Company maintained for that
purpose in The City of New York, in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
such interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Note Register.

      The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. Interest will accrue from each
prior Interest Payment Date to, but not including, the relevant payment date. In
the event that any date on which interest is payable on the Notes of this series
is not a Business Day at any Place of Payment, then payment of interest or
principal and premium, if any, need not be made at such Place of Payment on such
date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, and, if such payment is made or
duly provided for on such Business Day, no interest shall accrue on the amount
so payable for the period from and after such Interest Payment Date, Redemption
Date or Stated Maturity, as the case may be, to such Business Day. A "Business
Day" means when used with respect to a Place of Payment or any other particular
location specified in the Indenture, means any day, other than a Saturday or
Sunday, which is not a day on which banking institutions or trust companies in
such Place of Payment or other location are generally authorized or required by
law, regulation or executive order to remain closed.

      Reference is hereby made to the further provisions of this Note set forth
below, which further provisions shall for all purposes have the same effect as
if set forth at this place.

"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and Bankers Trust Company, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Notes and of the terms upon
which the Notes are, and are to be, authenticated and delivered. This Note is
one of the series designated on the face hereof, limited in aggregate principal
amount to $80,000,000.

      Prior to the Release Date (as hereinafter defined), this Note will be
secured by first mortgage bonds (the "Senior Note First Mortgage Bonds")
delivered by the Company to the Trustee for the benefit of all Holders of Notes
from time to time Outstanding, issued under the Indenture, dated as of April 1,
1932, between the Company and Bankers Trust Company, as trustee, as supplemented
and amended from time to time (the "First Mortgage"). Reference is made to the
First Mortgage for a description of property mortgaged and pledged, the nature
and extent of the security, the rights of the holders of the first mortgage
bonds under the First Mortgage and of the Mortgage Trustee in respect thereof,
the duties and immunities of the Mortgage Trustee and the terms and conditions
upon which the Senior Note First Mortgage Bonds are secured and the

      FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS, OTHER THAN FIRST
MORTGAGE BONDS WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED EITHER FIVE
PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION, HAVE
BEEN RETIRED THROUGH REPAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE FIRST
MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH
THE FIRST MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT NO
DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE "RELEASE DATE"),
THE SENIOR NOTE FIRST MORTGAGE BONDS SHALL CEASE TO SECURE THE NOTES IN ANY
MANNER.

      The Notes of this series are subject to redemption by the Company, at its
option, in whole, at any time, or in part, from time to time, upon notice as
provided in the Indenture (not less than 30 nor more than 60 days prior to a
date fixed for redemption (the "Redemption Date")) as follows: [     ]

      If notice has been given as provided in the Indenture and funds for the
redemption of any Notes (or any portion thereof) called for redemption shall
have been made available on the redemption date referred to in such notice, such
Notes (or any portion thereof) will cease to bear interest on the date fixed for
such redemption specified in such notice and the only right of the Holders of
such Notes will be to receive payment of the Redemption Price.

      Notice of any optional redemption of Notes of this series (or any portion
thereof) will be given to Holders at their addresses, as shown in the Note
Register for such Notes, not more than 60 nor less than 30 days prior to the
date fixed for redemption. The notice of redemption will specify, among other
items, the method of calculation of the Redemption Price and the principal
amount of the Notes held by such Holder to be redeemed. If less than all of the
Notes are to be redeemed at the option of the Company, the Trustee shall select,
in such manner as it shall deem fair and appropriate, the portion of such Note
to be redeemed in whole or in part.

      The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Note upon compliance with certain conditions set forth in
the Indenture.

amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes to be affected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of specified percentages of the Notes Outstanding. The Indenture also
contains provisions permitting the Holders of specified percentages in principal
amount of the Notes at the time Outstanding, on behalf of the Holders of all
Notes, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange therefor or
in lieu hereof, whether or not notation of such consent or waiver is made upon
this Note.

      As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Notes of this series, the Holders of not less than a majority in aggregate
principal amount of the Notes of all series at the time Outstanding in respect
of which an Event of Default shall have occurred and be continuing shall have

Event of Default shall have occurred and be continuing a direction inconsistent
with such request, and shall have failed to institute any such proceeding for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Note for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the times, place and rate, and in the coin or currency, herein
prescribed.

                Registration Statement on Form S-3 with respect to $80,000,000
                Senior Notes secured by $80,000,000 First Mortgage Bonds

Ladies and Gentlemen:

      In connection with the registration of $80,000,000 of the Company's Senior
Notes (the "Senior Notes") secured by $80,000,000 of the Company's First
Mortgage Bonds (the "First Mortgage Bonds") under the Securities Act of 1933, as
amended (the "Act"), we have examined the Registration Statement on Form S-3
(the "Registration Statement") and such corporate records, other documents and
questions of law as we considered necessary for the purpose of this opinion.

      On the basis of such examination, it is our opinion, assuming (i) the
applicable provisions of the Securities Act, the Trust Indenture Act of 1939, as
amended, and the securities or "blue sky" laws of various states shall have been
complied with, (ii) the Indenture (for Senior Notes) between the Company and
Bankers Trust Company, as Trustee, and the Supplemental Indentures relating to
the Senior Notes and First Mortgage Bonds shall have been duly authorized,
executed and delivered, (iii) the Senior Notes shall have been duly authorized,
executed, authenticated and delivered against the consideration therefor to be
set forth in the supplement or supplements to the prospectus constituting a part
of the Registration Statement and (iv) the First Mortgage Bonds have been duly
authorized, executed, authenticated and delivered to the Senior Note Trustee in
connection with the issuance of the Senior Notes, that the Senior Notes and
First Mortgage Bonds will be legally issued, fully paid, non-assessable and
binding obligations of the Company, except as limited by bankruptcy, insolvency,
reorganization, fraudulent conveyance or other similar laws affecting creditors'
rights and general equitable principles (regardless of whether enforceability is
considered in a proceeding in equity or at law).

      We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement.

                                        Yours very truly,
                                        BAMBERGER, FOREMAN, OSWALD AND HAHN

                                    ARTICLE I

                            MEETINGS OF STOCKHOLDERS

SECTION 1. The annual meeting of the stockholders of this Company shall be held

the third Tuesday in January of each year, for the election of directors and
such other business as may properly come before said meeting.

SECTION 2. Special meetings of stockholders other than those regulated by
statute may be called at any time by a majority of the directors. It shall be
the duty of the Chairman of the Board, the Chief Executive Officer or the
President to call such meetings whenever requested in writing to do so by
stockholders owning a majority of the capital stock.

SECTION 3. At all meetings of stockholders, there shall be present, either in
person or by proxy, stockholders owning a majority of the capital stock of the
Company, in order to constitute a quorum, except at special elections of
directors, as provided by law, but less than a quorum shall have power to
adjourn any meeting.

SECTION 4. The Chairman of the Board or, in his absence, the Chief Executive
Officer or, in his absence, the President or, in their absence, the senior
officer present, shall preside at meetings of the stockholders and shall direct
the proceedings and the order of business. The Secretary shall act as secretary
of such meetings and record the proceedings.

                                   ARTICLE II

                                    DIRECTORS

SECTION 1. The affairs of the Company shall be managed and its corporate powers
exercised by a Board of Directors consisting of such number of directors, but
not less than ten nor more than twenty-five, as may from time to time be fixed
by resolution adopted by a majority of the directors then in office, or by the
stockholders. In the event of any increase in the number of directors,
additional directors may be elected within the limitations so fixed, either by
the stockholders or within the limitations imposed by law, by a majority of
directors then in office. One-third of the number of directors, as fixed from
time to time, shall constitute a quorum. Any one or more members of the Board of
Directors or any Committee thereof may participate in a meeting of the Board of
Directors or Committee thereof by means of a conference telephone or similar

to hear each other at the same time. Participation by such means shall
constitute presence in person at such a meeting.
<PAGE>

All directors hereafter elected shall hold office until the next annual meeting
of the stockholders and until their successors are elected and have qualified.
No person who shall have attained age 72 shall be eligible to be elected or
re-elected a director. Such director may, however, remain a director of the
Company until the next annual meeting of the stockholders of Bankers Trust New
York Corporation (the Company's parent) so that such director's retirement will
coincide with the retirement date from Bankers Trust New York Corporation.

No Officer-Director who shall have attained age 65, or earlier relinquishes his
responsibilities and title, shall be eligible to serve as a director.

SECTION 2. Vacancies not exceeding one-third of the whole number of the Board of
Directors may be filled by the affirmative vote of a majority of the directors
then in office, and the directors so elected shall hold office for the balance
of the unexpired term.

SECTION 3. The Chairman of the Board shall preside at meetings of the Board of
Directors. In his absence, the Chief Executive Officer or, in his absence, such
other director as the Board of Directors from time to time may designate shall
preside at such meetings.

SECTION 4. The Board of Directors may adopt such Rules and Regulations for the
conduct of its meetings and the management of the affairs of the Company as it
may deem proper, not inconsistent with the laws of the State of New York, or
these By-Laws, and all officers and employees shall strictly adhere to, and be
bound by, such Rules and Regulations.

SECTION 5. Regular meetings of the Board of Directors shall be held from time to
time on the third Tuesday of the month. If the day appointed for holding such
regular meetings shall be a legal holiday, the regular meeting to be held on
such day shall be held on the next business day thereafter. Special meetings of
the Board of Directors may be called upon at least two day's notice whenever it
may be deemed proper by the Chairman of the Board or, the Chief Executive
Officer or, in their absence, by such other director as the Board of Directors
may have designated pursuant to Section 3 of this Article, and shall be called
upon like notice whenever any three of the directors so request in writing.

SECTION 6. The compensation of directors as such or as members of committees
shall be fixed from time to time by resolution of the Board of Directors.

                                   ARTICLE III

                                   COMMITTEES

SECTION 1. There shall be an Executive Committee of the Board consisting of not
less than five directors who shall be appointed annually by the Board of
Directors. The Chairman of the Board shall preside at meetings of the Executive
Committee. In his absence, the Chief Executive Officer or, in his absence, such
other member of the Committee as the Committee from time to time may designate
shall preside at such meetings.

The Executive Committee shall possess and exercise to the extent permitted by
law all of the powers of the Board of Directors, except when the latter is in
session, and shall keep minutes of its proceedings, which shall be presented to
the Board of Directors at its next subsequent meeting. All acts done and powers
and authority conferred by the Executive Committee from time to time shall be
and be deemed to be, and may be certified as being, the act and under the
authority of the Board of Directors.

A majority of the Committee shall constitute a quorum, but the Committee may act
only by the concurrent vote of not less than one-third of its members, at least
one of whom must be a director other than an officer. Any one or more directors,
even though not members of the Executive Committee, may attend any meeting of
the Committee, and the member or members of the Committee present, even though
less than a quorum, may designate any one or more of such directors as a
substitute or substitutes for any absent member or members of the Committee, and
each such substitute or substitutes shall be counted for quorum, voting, and all
other purposes as a member or members of the Committee.

SECTION 2. There shall be an Audit Committee appointed annually by resolution
adopted by a majority of the entire Board of Directors which shall consist of
such number of directors, who are not also officers of the Company, as may from
time to time be fixed by resolution adopted by the Board of Directors. The
Chairman shall be designated by the Board of Directors, who shall also from time
to time fix a quorum for meetings of the Committee. Such Committee shall conduct
the annual directors' examinations of the Company as required by the New York
State Banking Law; shall review the reports of all examinations made of the
Company by public authorities and report thereon to the Board of Directors; and
shall report to the Board of Directors such other matters as it deems advisable
with respect to the Company, its various departments and the conduct of its
operations.

In the performance of its duties, the Audit Committee may employ or retain, from
time to time, expert assistants, independent of the officers or personnel of the
Company, to make studies of the Company's assets and liabilities as the
Committee may request and to make an examination of the accounting and auditing
methods of the Company and its system of internal protective controls to the
extent considered necessary or advisable in order to determine that the
operations of the Company, including its fiduciary departments, are being
audited by the General Auditor in such a manner as to provide prudent and
adequate protection. The Committee also may direct the General Auditor to make
such investigation as it deems necessary or advisable with respect to the
Company, its various departments and the conduct of its operations. The
Committee shall hold regular quarterly
<PAGE>

meetings and during the intervals thereof shall meet at other times on call of
the Chairman.

SECTION 3. The Board of Directors shall have the power to appoint any other
Committees as may seem necessary, and from time to time to suspend or continue
the powers and duties of such Committees. Each Committee appointed pursuant to
this Article shall serve at the pleasure of the Board of Directors.

                                   ARTICLE IV

Chairman or any Vice Chairman, may from time to time appoint assistant officers.
All officers elected or appointed by the Board of Directors shall hold their
respective offices during the pleasure of the Board of Directors, and all
assistant officers shall hold office at the pleasure of the Board or the
Chairman of the Board or the Chief Executive Officer or, in their absence, the

performance of their duties.

SECTION 2. The Board of Directors shall designate the Chief Executive Officer of
the Company who may also hold the additional title of Chairman of the Board,
President, Senior Vice Chairman or Vice Chairman and such person shall have,
subject to the supervision and direction of the Board of Directors or the
Executive Committee, all of the powers vested in such Chief Executive Officer by
law or by these By-Laws, or which usually attach or pertain to such office. The
other officers shall have, subject to the supervision and direction of the Board
of Directors or the Executive Committee or the Chairman of the Board or, the
Chief Executive Officer, the powers vested by law or by these By-Laws in them as
holders of their respective offices and, in addition, shall perform such other
duties as shall be assigned to them by the Board of Directors or the Executive
Committee or the Chairman of the Board or the Chief Executive Officer.

The General Auditor shall be responsible, through the Audit Committee, to the
Board of Directors for the determination of the program of the internal audit
function and the evaluation of the adequacy of the system of internal controls.
Subject to the Board of Directors, the General Auditor shall have and may
exercise all the powers and shall perform all the duties usual to such office
and shall have such other powers as may be prescribed or assigned to him from
time to time by the Board of Directors or vested in him by law or by these
By-Laws. He shall perform such other duties and shall make such investigations,
examinations and reports as may be prescribed or required by the Audit
<PAGE>

Committee. The General Auditor shall have unrestricted access to all records and
premises of the Company and shall delegate such authority to his subordinates.
He shall have the duty to report to the Audit Committee on all matters
concerning the internal audit program and the adequacy of the system of internal
controls of the Company which he deems advisable or which the Audit Committee
may request. Additionally, the General Auditor shall have the duty of reporting
independently of all officers of the Company to the Audit Committee at least
quarterly on any matters concerning the internal audit program and the adequacy
of the system of internal controls of the Company that should be brought to the
attention of the directors except those matters responsibility for which has
been vested in the General Credit Auditor. Should the General Auditor deem any
matter to be of special immediate importance, he shall report thereon forthwith
to the Audit Committee. The General Auditor shall report to the Chief Financial
Officer only for administrative purposes.

The General Credit Auditor shall be responsible to the Chief Executive Officer
and, through the Audit Committee, to the Board of Directors for the systems of
internal credit audit, shall perform such other duties as the Chief Executive
Officer may prescribe, and shall make such examinations and reports as may be
required by the Audit Committee. The General Credit Auditor shall have
unrestricted access to all records and may delegate such authority to
subordinates.

                                    ARTICLE V

                INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

SECTION 1. The Company shall, to the fullest extent permitted by Section 7018 of
the New York Banking Law, indemnify any person who is or was made, or threatened
to be made, a party to an action or proceeding, whether civil or criminal,
whether involving any actual or alleged breach of duty, neglect or error, any
accountability, or any actual or alleged misstatement, misleading statement or
other act or omission and whether brought or threatened in any court or
administrative or legislative body or agency, including an action by or in the
right of the Company to procure a judgment in its favor and an action by or in
the right of any other corporation of any type or kind, domestic or foreign, or
any partnership, joint venture, trust, employee benefit plan or other
enterprise, which any director or officer of the Company is servicing or served
in any capacity at the request of the Company by reason of the fact that he, his
testator or intestate, is or was a director or officer of the Company, or is
serving or served such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise in any capacity, against judgments,
fines, amounts paid in settlement, and costs, charges and expenses, including
attorneys' fees, or any appeal therein; provided, however, that no
indemnification shall be provided to any such person if a judgment or other
final adjudication adverse to the director or officer establishes that (i) his
acts were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material to the cause of action so
adjudicated, or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

SECTION 2. The Company may indemnify any other person to whom the Company is
permitted to provide indemnification or the advancement of expenses by
applicable law, whether pursuant to rights granted pursuant to, or provided by,
the New York Banking Law or other rights created by (i) a resolution of
stockholders, (ii) a resolution of directors, or (iii) an agreement providing
for such indemnification, it being expressly intended that these By-Laws
authorize the creation of other rights in any such manner.

SECTION 3. The Company shall, from time to time, reimburse or advance to any
person referred to in Section 1 the funds necessary for payment of expenses,
including attorneys' fees, incurred in connection with any action or proceeding
referred to in Section 1, upon receipt of a written undertaking by or on behalf
of such person to repay such amount(s) if a judgment or other final adjudication
adverse to the director or officer establishes that (i) his acts were committed
in bad faith or were the result of active and deliberate dishonesty and, in
either case, were material to the cause of action so adjudicated, or (ii) he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.

SECTION 4. Any director or officer of the Company serving (i) another
corporation, of which a majority of the shares entitled to vote in the election
of its directors is held by the Company, or (ii) any employee benefit plan of
the Company or any corporation referred to in clause (i) in any capacity shall
be deemed to be doing so at the request of the Company. In all other cases, the
provisions of this Article V will apply (i) only if the person serving another
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise so served at the specific request of the Company, evidenced by
a written communication signed by the Chairman of the Board, the Chief Executive
Officer or
<PAGE>

the President, and (ii) only if and to the extent that, after making such
efforts as the Chairman of the Board, the Chief Executive Officer or the
President shall deem adequate in the circumstances, such person shall be unable
to obtain indemnification from such other enterprise or its insurer.

SECTION 5. Any person entitled to be indemnified or to the reimbursement or
advancement of expenses as a matter of right pursuant to this Article V may
elect to have the right to indemnification (or advancement of expenses)
interpreted on the basis of the applicable law in effect at the time of
occurrence of the event or events giving rise to the action or proceeding, to
the extent permitted by law, or on the basis of the applicable law in effect at
the time indemnification is sought.

SECTION 6. The right to be indemnified or to the reimbursement or advancement of
expense pursuant to this Article V (i) is a contract right pursuant to which the
person entitled thereto may bring suit as if the provisions hereof were set
forth in a separate written contract between the Company and the director or
officer, (ii) is intended to be retroactive and shall be available with respect
to events occurring prior to the adoption hereof, and (iii) shall continue to
exist after the rescission or restrictive modification hereof with respect to
events occurring prior thereto.

SECTION 7. If a request to be indemnified or for the reimbursement or
advancement of expenses pursuant hereto is not paid in full by the Company
within thirty days after a written claim has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled also to be paid the expenses of prosecuting such
claim. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in the
circumstance, nor an actual determination by the Company (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant is
not entitled to indemnification or to the reimbursement or advancement of
expenses, shall be a defense to the action or create a presumption that the
claimant is not so entitled.

SECTION 8. A person who has been successful, on the merits or otherwise, in the
defense of a civil or criminal action or proceeding of the character described
in Section 1 shall be entitled to indemnification only as provided in Sections 1
and 3, notwithstanding any provision of the New York Banking Law to the
contrary.

properly assigned for transfer.

SECTION 3. At all meetings of stockholders, there shall be present, either in
person or by proxy, stockholders owning a majority of the capital stock of the

these By-Laws, and all officers and employees shall strictly adhere to, and be
bound by, such Rules and Regulations.

SECTION 5. Regular meetings of the Board of Directors shall be held from time to
time on the third Tuesday of the month. If the day appointed for holding such
regular meetings shall be a legal holiday, the regular meeting to be held on
such day shall be held on the next business day thereafter. Special meetings of
the Board of Directors may be called upon at least two day's notice whenever it
may be deemed proper by the Chairman of the Board or, the Chief Executive
Officer or, in their absence, by such other director as the Board of Directors
may have designated pursuant to Section 3 of this Article, and shall be called
upon like notice whenever any three of the directors so request in writing.

SECTION 6. The compensation of directors as such or as members of committees
shall be fixed from time to time by resolution of the Board of Directors.

less than five directors who shall be appointed annually by the Board of
Directors. The Chairman of the Board shall preside at meetings of the Executive

session, and shall keep minutes of its proceedings, which shall be presented to
the Board of Directors at its next subsequent meeting. All acts done and powers
and authority conferred by the Executive Committee from time to time shall be
and be deemed to be, and may be certified as being, the act and under the
authority of the Board of Directors.

A majority of the Committee shall constitute a quorum, but the Committee may act
only by the concurrent vote of not less than one-third of its members, at least
one of whom must be a director other than an officer. Any one or more directors,
even though not members of the Executive Committee, may attend any meeting of
the Committee, and the member or members of the Committee present, even though
less than a quorum, may designate any one or more of such directors as a
substitute or substitutes for any absent member or members of the Committee, and
each such substitute or substitutes shall be counted for quorum, voting, and all
other purposes as a member or members of the Committee.

SECTION 2. There shall be an Audit Committee appointed annually by resolution
adopted by a majority of the entire Board of Directors which shall consist of

operations of the Company, including its fiduciary departments, are being
audited by the General Auditor in such a manner as to provide prudent and
adequate protection. The Committee also may direct the General Auditor to make
such investigation as it deems necessary or advisable with respect to the
Company, its various departments and the conduct of its operations. The
Committee shall hold regular quarterly

Committees as may seem necessary, and from time to time to suspend or continue
the powers and duties of such Committees. Each Committee appointed pursuant to
this Article shall serve at the pleasure of the Board of Directors.

law or by these By-Laws, or which usually attach or pertain to such office. The
other officers shall have, subject to the supervision and direction of the Board
of Directors or the Executive Committee or the Chairman of the Board or, the

                INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

SECTION 1. The Company shall, to the fullest extent permitted by Section 7018 of
the New York Banking Law, indemnify any person who is or was made, or threatened
to be made, a party to an action or proceeding, whether civil or criminal,
whether involving any actual or alleged breach of duty, neglect or error, any
accountability, or any actual or alleged misstatement, misleading statement or
other act or omission and whether brought or threatened in any court or
administrative or legislative body or agency, including an action by or in the
right of the Company to procure a judgment in its favor and an action by or in
the right of any other corporation of any type or kind, domestic or foreign, or
any partnership, joint venture, trust, employee benefit plan or other
enterprise, which any director or officer of the Company is servicing or served
in any capacity at the request of the Company by reason of the fact that he, his
testator or intestate, is or was a director or officer of the Company, or is
serving or served such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise in any capacity, against judgments,
fines, amounts paid in settlement, and costs, charges and expenses, including
attorneys' fees, or any appeal therein; provided, however, that no
indemnification shall be provided to any such person if a judgment or other
final adjudication adverse to the director or officer establishes that (i) his
acts were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material to the cause of action so
adjudicated, or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

SECTION 2. The Company may indemnify any other person to whom the Company is
permitted to provide indemnification or the advancement of expenses by
applicable law, whether pursuant to rights granted pursuant to, or provided by,
the New York Banking Law or other rights created by (i) a resolution of
stockholders, (ii) a resolution of directors, or (iii) an agreement providing
for such indemnification, it being expressly intended that these By-Laws
authorize the creation of other rights in any such manner.

SECTION 3. The Company shall, from time to time, reimburse or advance to any
person referred to in Section 1 the funds necessary for payment of expenses,
including attorneys' fees, incurred in connection with any action or proceeding
referred to in Section 1, upon receipt of a written undertaking by or on behalf
of such person to repay such amount(s) if a judgment or other final adjudication
adverse to the director or officer establishes that (i) his acts were committed
in bad faith or were the result of active and deliberate dishonesty and, in
either case, were material to the cause of action so adjudicated, or (ii) he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.

SECTION 4. Any director or officer of the Company serving (i) another
corporation, of which a majority of the shares entitled to vote in the election
of its directors is held by the Company, or (ii) any employee benefit plan of
the Company or any corporation referred to in clause (i) in any capacity shall
be deemed to be doing so at the request of the Company. In all other cases, the
provisions of this Article V will apply (i) only if the person serving another
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise so served at the specific request of the Company, evidenced by
a written communication signed by the Chairman of the Board, the Chief Executive
Officer or the President, and (ii) only if and to the extent that, after making
such efforts as the Chairman of the Board, the Chief Executive Officer or

<PAGE>

the President shall deem adequate in the circumstances, such person shall be
unable to obtain indemnification from such other enterprise or its insurer.

SECTION 5. Any person entitled to be indemnified or to the reimbursement or
advancement of expenses as a matter of right pursuant to this Article V may
elect to have the right to indemnification (or advancement of expenses)
interpreted on the basis of the applicable law in effect at the time of
occurrence of the event or events giving rise to the action or proceeding, to
the extent permitted by law, or on the basis of the applicable law in effect at
the time indemnification is sought.

SECTION 6. The right to be indemnified or to the reimbursement or advancement of
expense pursuant to this Article V (i) is a contract right pursuant to which the
person entitled thereto may bring suit as if the provisions hereof were set
forth in a separate written contract between the Company and the director or
officer, (ii) is intended to be retroactive and shall be available with respect
to events occurring prior to the adoption hereof, and (iii) shall continue to
exist after the rescission or restrictive modification hereof with respect to
events occurring prior thereto.

SECTION 7. If a request to be indemnified or for the reimbursement or
advancement of expenses pursuant hereto is not paid in full by the Company
within thirty days after a written claim has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled also to be paid the expenses of prosecuting such
claim. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in the
circumstance, nor an actual determination by the Company (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant is
not entitled to indemnification or to the reimbursement or advancement of
expenses, shall be a defense to the action or create a presumption that the
claimant is not so entitled.

SECTION 8. A person who has been successful, on the merits or otherwise, in the
defense of a civil or criminal action or proceeding of the character described
in Section 1 shall be entitled to indemnification only as provided in Sections 1
and 3, notwithstanding any provision of the New York Banking Law to the
contrary.
