                     ABOUT NIAGARA MOHAWK POWER CORPORATION

NIAGARA MOHAWK POWER CORPORATION

     We were organized in 1937 under the laws of New York State and are engaged
principally in the regulated energy delivery business in New York State. We
provide electric service, and we sell, distribute and transport natural gas to
approximately 1,600,000 electric and 560,000 gas customers in areas of central,
northern and western New York State.

     On March 18, 1999, we were reorganized into a holding company structure in
accordance with the Agreement and Plan of Exchange between Niagara Mohawk
Holdings, Inc. and us. Our outstanding common stock was exchanged on a
share-for-share basis for the common stock of Niagara Mohawk Holdings, Inc. Our
debt and preferred stock were not exchanged as a part of the share exchange and
continue as our obligations. See "Where You Can Find More Information" for how
you can find more information about the reorganization and about us.

RECENT DEVELOPMENT

     In 1999, the New York State Public Service Commission approved our petition
to purchase up to $800 million of Niagara Mohawk Holdings, Inc. common stock. In
July 1999, the board of directors of Niagara Mohawk Holdings, Inc. approved a
program to repurchase 20 million shares through December 31, 2001 and in March
2000 the board of directors authorized and approved the repurchase of an
additional 20 million shares through December 31, 2002. As of December 31, 1999,
we repurchased 10 million shares of the common stock of Niagara Mohawk Holdings,
Inc. Additional 5 million shares were repurchased by an agent on our behalf, but
were not paid for by us (with the exception of $1.4 million in carrying charges)
and remain in the number of shares outstanding in computing the earnings per
share of Niagara Mohawk Holdings, Inc.

                                USE OF PROCEEDS

     Unless we state otherwise in the prospectus supplement, we will use the
proceeds from the sale of the Securities offered under this prospectus and the
prospectus supplement for general corporate purposes. Our general corporate
purposes may include:

     - the finance of our construction program;

     - refund existing long term-debt and preferred stock;

     - refund short term debt;

     - the finance of termination or restructuring of Power Purchase Agreements
       with Independent Power Producers; and

     - repurchase common stock of Niagara Mohawk Holdings, Inc.

                      RATIOS OF EARNINGS TO FIXED CHARGES

     Our consolidated ratios of earnings to fixed charges for each of the fiscal
years ended December 31, 1995 through 1999 are as follows:

<TABLE>
<CAPTION>
        YEARS ENDED DECEMBER 31,
  ------------------------------------
  1999    1998   1997    1996    1995

  x1.01   x.57   x2.02   x1.57   x2.29
</TABLE>

     For purposes of computing these ratios, earnings consist of income before
income taxes plus fixed charges. Fixed charges consist of: (a) interest expenses
and amortization of debt expenses as reported in our consolidated financial
statements; (b) dividends on preferred stock of subsidiary companies; (c) the
portion of net rental expense which is deemed representative of the interest
factor inherent in rents and (d) the cumulative effect of accounting changes.

                     DESCRIPTION OF SECURITIES WE MAY OFFER

     The Securities issued under this prospectus are governed by documents
called the "INDENTURES". The Indenture governing the First Mortgage Bonds is a
contract between us and HSBC. The Indenture governing our unsecured debt
securities is a contract between us and The Bank of New York. Each of these
banks currently acts as "TRUSTEE" under the Indenture to which it is a party.

     Each Trustee has two main roles:

     - First, the Trustee can enforce your rights against us if we default.
       There are some limitations on the extent to which the Trustee acts on
       your behalf, which we describe later under "Description of New
       Bonds -- Events of Default" and "Description of New Debentures -- Events
       of Default."

     - Second, the Trustee performs administrative duties for us, which include
       sending you interest payments, transferring your debt securities to a new
       buyer if you sell and sending you notices.

     In this description, we refer to the First Mortgage Bonds as "NEW BONDS"
and the unsecured debt securities as the "NEW DEBENTURES." When we say "BOND" we
mean any bond that has been, or will be, delivered under the Indenture that
governs the New Bonds. When we say "Securities" we collectively refer to the New
Bonds and the New Debenture. A copy of each Indenture is filed as an exhibit to
the registration statement relating to the Securities.

     Each Indenture permits us to issue different series of Securities from time
to time. We may issue securities in such amounts, at such times and on such
terms as we wish. The Securities may differ from one another in their terms.

     Securities may be sold at prices substantially below their face value, and
may be denominated in foreign currencies. The prospectus supplement will
describe:

     - special United States federal income tax or other considerations, if any,
       with respect to Securities sold at original issue discount.

     - special United States federal income tax and other considerations, if
       any, with respect to Securities which are denominated in a currency or
       currency unit other than United States dollars.

     Unless otherwise indicated in the prospectus supplement, the covenants
contained in the Indentures and the Securities will not afford holders of the
Securities protection in the event of a sudden decline in credit rating that
might result from a recapitalization, restructuring, or other highly leveraged
transaction.

THIS SECTION IS ONLY A SUMMARY

     The Indentures and their associated documents, including your Securities,
contain the full legal text of the matters described in this section. A copy of
each Indenture has been filed with the SEC as part of our registration
statement. See "Where You Can Find More

                                        2

Information" on page 15 for information on how to obtain a copy.

     This section summarizes the material terms that will apply generally to the
Securities. Each particular series of Securities will have financial and other
terms specific to it, and these specific terms will be described in the
prospectus supplement. As you read this section, therefore, please remember that
the specific terms of your Securities as described in your prospectus supplement
will supplement and, if applicable, may modify or replace the general terms
described in this section. The statements we make in this section may not apply
to your Securities.

   IN THE REMAINDER OF THIS DESCRIPTION "YOU" MEANS DIRECT HOLDERS AND NOT
   "STREET NAME" OR OTHER INDIRECT HOLDERS OF DEBT SECURITIES. INDIRECT
   HOLDERS SHOULD READ THE SUBSECTION ON PAGE 12 ENTITLED "STREET NAME" AND
   OTHER INDIRECT HOLDERS".

                            DESCRIPTION OF NEW BONDS

TERMS OF THE NEW BONDS

     You should refer to the prospectus supplement for the following information
about a particular series of New Bonds:

     - the designation and principal amounts of the New Bonds;

     - the date on which the New Bonds mature;

     - the interest rate;

     - when the interest on the New Bonds accrues and is payable;

     - the dates on which interest on the New Bonds will be payable;

     - whether, when and at what price we can redeem the New Bonds; and

     - any other specific terms of the New Bonds.

THE MORTGAGE

     The New Bonds are secured by a "MORTGAGE" which will create a direct first
lien on substantially all gas and electric properties that we now own or use or
are useful in the operation of our properties as an integrated system. The
mortgage lien will also extend to all property of the same nature we acquire
after the effective date of the Mortgage. The Mortgage will not extend to
property that we acquire through merger or consolidation or a purchase of
substantially all the assets of other corporations, unless we decide otherwise.

     This lien DOES NOT EXTEND to:

     - revenues and profits of the mortgaged property;

     - any bills;

     - notes;

     - accounts receivable;

     - cash (except cash deposited with the trustee);

     - agreements;

     - securities;

     - materials and supplies; and

     - all oil, gas and other minerals and the right to this removal.

     This lien is SUBJECT TO:

     - liens for taxes and assessments not due and payable or being contested in
       good-faith;

     - obligations to public authorities as to any franchise, consent, grant,
       license or permit;

     - leases and other rights of tenants and of licensees; and

     - the rights of others to property acquired after the effective date of the
       Mortgage for transmission or distribution systems

                                        3
<PAGE>   6

       or right-of-way purposes (Granting Clause of the Mortgage).

     The direct lien on our properties is also subject to other minor types of
encumbrances which do not materially interfere with the operation of our
business. These encumbrances may include:

     - rights and claims of third parties in possession which are not disclosed
       of record;

     - any facts that can only be disclosed by an accurate survey;

     - the effect of zoning ordinances;

     - rights of public in the use of streets, roads and waterways; and

     - leases, covenants, easements.

RANKING

     The New Bonds will rank on an equal basis with all other mortgage Bonds
issued under the Mortgage.

CREDIT ENHANCEMENT

     We will provide you further information in the prospectus supplement if any
series of New Bonds shall be entitled to the benefits of a surety bond or other
form of credit enhancement.

ADDITIONAL NEW BONDS

     The Mortgage provides that we may not create any securities which will rank
senior to the New Bonds as to security. However, we may acquire property which
is subject to other liens and mortgage after-acquired property which is not
subject to the lien of the property.

     Additional New Bonds which will rank equally as to security with the New
Bonds including prior lien New Bonds may be issued under the Mortgage in an
unlimited amount only as follows:

          1.  additional New Bonds may be issued in a principal amount equal to
     60% of the net (which was in excess of $300 million on December 31, 1999)
     of property additions that are not subject to an unfunded prior lien;

          2.  we may issue additional New Bonds in exchange for bonds
     outstanding under the Mortgage or in substitution for bonds that were
     retired (which was in excess of $1.0 billion on December 31, 1999); and

          3.  additional New Bonds may be issued in a principal amount equal to
     the amount of cash we deposit with the Trustee for that purpose.

     Additional New Bonds described in paragraphs 1 and 3 above MAY NOT be
issued unless our net earnings over a certain period (12 out of the 15 preceding
months) that are available for interest, after a provision for depreciation but
before income taxes, are at least 1.75 times the annual interest charges on all
Bonds and prior lien bonds then outstanding or applied for.

     We expect to offer the New Bonds on the basis of property additions, cash
deposited with the Trustee or Bonds that have been retired or will be retired or
purchased pursuant to sinking fund payments.

RELEASES OF PROPERTY

     We may release property subject to the lien of the Mortgage, other than
cash and prior lien bonds, upon any sale, exchange, condemnation or
expropriation of the property subject to the Mortgage without furnishing notice
to the bondholders. Any property, other than cash or securities, we received
upon the release of mortgaged property shall be subject to the lien of the
Mortgage, and any cash or securities received shall, unless we use it to satisfy
some prior lien, become part of the security for the Bonds issued under the
mortgage.

     We may withdraw monies received by the Trustee as proceeds of released
property to reimburse us for retirement of Bonds and certain prior lien bonds,
or to pay, purchase or redeem these Bonds or prior lien bonds. We may also
withdraw cash in an amount equal to 166 2/3% of the principal amount of Bonds
which

                                        4
<PAGE>   7

we could issue under the Mortgage in respect of Additional Property, provided we
forgo the right to issue these Bonds. In the ordinary course of business and
otherwise, we regularly obtain from the Trustee the release of various
properties from the lien of the Mortgage. In the case of exchanges of property,
no exchange shall be made if our Funded Indebtedness is increased as a result.
(Mortgage, Articles Sixth and Seventh.)

     When we say "Additional Property" we refer to any property that we acquired
after July 31, 1937, that is used or useful in our business and which will
become subject to the first mortgage lien. Additional property will not include:

     - property which is generally charged by us to operating expenses in
       accordance with our accounting practices;

     - equipment, material and supplies we acquire for the purpose of resale in
       the usual course of business;

     - goodwill, franchises or governmental permits;

     - property we acquire as a substitute for a released property that is
       subject to the Mortgage, but only to the extent of the consideration
       received for the mortgaged property;

     - cash, accounts receivables, stocks, bonds and other evidence of
       indebtedness; and

     - any insurance proceeds we receive from the Trustee as reimbursement for
       loss or damage to property, but only to the extent of the insurance
       proceeds received.

     When we say "funded indebtedness" we refer to the aggregate unpaid
principal amount at any particular time of the Company's:

     - issued and outstanding Bonds that we issue under the Mortgage, including
       the additional Bonds that are about to be issued;

     - all issued and outstanding bonds secured by a lien which is ranked prior
       to, or equally with, the first mortgage lien; and

     - all issued and outstanding bonds that are secured by any other lien and
       are not subject to the first mortgage lien.

MAINTENANCE FUND PROVISIONS

     We are required within 90 days after the close of each fiscal year, to (a)
certify the Costs of Additional Property (b) deposit with the Trustee cash,
Bonds or certain prior lien bonds; or (c) waive our right to the authentication
and delivery of the principal amount of Bonds to which we are then entitled
under the Mortgage, to the extent that the aggregate amount of expenditure for
maintenance, repairs, renewals and replacements for the period commencing
January 1, 1977 is less than the sum of 2.25% of our depreciable property (as
defined) on January 1 of each year during such period (Mortgage, Article Fifth,
section 22).

RESTRICTION ON COMMON STOCK DIVIDEND

     To the extent that the aggregate amount of expenditure for maintenance and
repairs, plus the aggregate amount credited to depreciation, retirements and
other like reserves, for the period commencing January 1, 1977 is less than the
sum of 2.25% of our depreciable property on January 1 of each year during that
period, we must reserve an equivalent amount of surplus and hold it unavailable
for distribution as a dividend on our common stock. (Mortgage, Article Fifth,
section 23).

MERGERS AND SIMILAR EVENTS

     We are generally permitted to consolidate or merge with another company or
sell substantially all of our assets to another company as long as the following
conditions are met:

     - we are not in default under the Mortgage;

     - the terms of the merger or consolidation or sale of the our assets may
       not impair the lien, the security of the Mortgage, the rights and powers
       of the Trustee or the rights and powers of the bondholders;

     - if we are not the surviving corporation, or in the case of a sale of our
       assets, the
                                        5
<PAGE>   8

       successor corporation assumes by supplemental indenture our obligations
       under the Mortgage.

MODIFICATION

     From time to time, we may unilaterally modify the Mortgage by entering into
a supplemental indenture with the Trustee to:

     - correct property descriptions;

     - modify the Mortgage or form of bonds and coupons to facilitate stock
       exchange listing requirements; or

     - cure any ambiguity or errors in the Mortgage;

but only if the amendments are not inconsistent with the terms of the Mortgage
and shall not impair the security of the Bonds.

     The Mortgage also permits us and the Trustee to modify the Mortgage in any
manner whatsoever. A vote of the holders of Bonds owning 66 2/3% of the
principal amount of the total amount of outstanding Bonds, excluding Bonds owned
by us or by our affiliates, is required to effect this change to the Mortgage.

     However, we and the Trustee may not modify the Mortgage in the following
ways without the consent of the holder of each outstanding Bonds:

     - alter or impair our obligation to pay the principal and interest on the
       Bonds;

     - create a mortgage or a lien in the nature of a mortgage that ranks prior
       to, or equally with, the first mortgage lien;

     - any change to the Mortgage that adversely affects your rights; or

     - reduce the percentage of bondholders that is required to consent to a
       modification to the Mortgage.

     We may not modify the Mortgage without the consent of the Trustee if the
Trustee is affected by the modification.
EVENTS OF DEFAULT

     You will have special rights if an Event of Default occurs and is not
cured, as described later in this subsection.

     The term "EVENT OF DEFAULT" for the New Bonds means any of the following:

     - we do not pay the principal of or any premium on a New Bond on its due
       date;

     - we do not pay interest on a New Bond within 60 days after its Due Date;

     - we do not deposit any sinking, improvement, maintenance or similar fund
       payment on its due date;

     - we remain in breach of a covenant of the Mortgage for 90 days after we
       receive a notice of default stating we are in breach. The notice must be
       sent by the Trustee in its discretion or upon the written request of 25%
       of the bondholders; and

     - we file for bankruptcy, insolvency or reorganization events that involve
       us.

     If an Event of Default has occurred and has not been cured within 90 days,
the Trustee will notify the bondholders as to our default. The Mortgage allows
the Trustee to withhold notice of default if the Trustee determines in good
faith that withholding the notice is in the interests of the bondholders. The
Trustee may not withhold notice of any default in the payment of principal,
interest, installments upon retirement or any sinking or purchase fund.

     Prior to exercising his powers to enforce the Mortgage, the Trustee is
entitled to reasonable protection from expenses and liability (called an
"INDEMNITY").

   "STREET NAME" AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS OR
   BROKERS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A
   REQUEST OF THE TRUSTEE.

                                        6
<PAGE>   9

     The Mortgage does not require us to furnish periodic evidence to the
trustee as to the absence of default or as to our compliance with the terms of
the mortgage. However, the Mortgage requires that as a condition to the issuance
of additional Bonds, including New Bonds, we will be in compliance with any
covenant contained in the mortgage.

                       DESCRIPTION OF THE NEW DEBENTURES

TERMS OF THE NEW DEBENTURES

     You should refer to the prospectus supplement for the following information
about a particular series of New Debentures:

     - the designation and principal amounts of the New Debentures;

     - the date on which the New Debentures mature;

     - the interest rate;

     - when the interest on the New Debentures accrues and is payable;

     - the dates on which interest on the New Debentures will be payable;

     - whether, when and at what price we can redeem the New Debentures; and

     - any other specific terms of the New Debentures.

CONVERSION

     Your New Debentures may be convertible into or exchangeable for common
stock or other securities if your prospectus supplement so provides. If your New
Debentures are convertible or exchangeable, your prospectus supplement will
include provisions as to:

     - whether the New Debentures are convertible or exchangeable into our
       common stock or other securities we issue or into common stock or other
       securities of other issuers;

     - whether the conversion or exchange is mandatory, at your option or our
       option;

     - whether adjustments may be made in the number of shares of common stock
       or other securities to be received by you upon conversion or exchange.

MERGERS AND SIMILAR EVENTS

     We are generally permitted to consolidate or merge with another company or
sell substantially all of our assets to another company as long as the following
conditions are met:

     - we are not in default under the Indenture;

     - where we merge out of existence or sell our assets, the other firm may
       not be organized under a foreign country's laws (that is, it must be a
       corporation, partnership, trust or other entity organized under the laws
       of a State or the District of Columbia or under federal law); and

     - if we are not the surviving corporation, or in the case of a sale of our
       assets, the successor corporation assumes by supplemental indenture our
       obligations under the Indenture.

MODIFICATION AND WAIVER

     There are three types of changes we can make to the Indenture and the New
Debentures.

     CHANGES REQUIRING YOUR APPROVAL.  First, there are changes that cannot be
made to your New Debentures without your specific approval.

     Following is a list of those types of changes:

     - change the Stated Maturity of the principal of or interest on any New
       Debenture;

     - reduce any amounts due on any New Debenture;

     - reduce the amount of principal payable upon acceleration of the Maturity
       of any New Debenture following a default;

                                        7
<PAGE>   10

     - change the place or currency of payment on any New Debenture;

     - impair your right to sue for payment;

     - reduce the percentage of holders of New Debentures whose consent is
       needed to modify or amend the Indenture;

     - reduce the percentage of holders of New Debentures whose consent is
       needed to waive compliance with certain provisions of the Indenture or to
       waive certain defaults; and

     - modify any other aspect of the provisions dealing with modification and
       waiver of the Indenture. (Section 902)

     CHANGES REQUIRING A MAJORITY VOTE.  The second type of change to the
Indenture and the New Debentures is the kind that requires a vote in favor by
holders of New Debentures owning a majority amount of the particular series
affected. Most changes fall into this category, except for changes noted above
as requiring your specific vote, and, as we note below, changes which do not
require your approval. The same vote would be required for us to obtain a waiver
of any past defaults. However, we cannot obtain a waiver of a payment default or
any other aspect of the Indenture or the New Debentures listed in the first
category described above under "-- Changes Requiring Your Approval" unless we
obtain your individual consent to the waiver. (Section 513)

     CHANGES NOT REQUIRING APPROVAL.  The third type of change does not require
any approval by holders of New Debentures. This type is limited to
clarifications and certain other changes that would not adversely affect holders
of the New Debentures.
     FURTHER DETAILS CONCERNING VOTING.  When taking a vote, we will use the
following rules to decide how much principal amount to attribute to a New
Debenture:

     - For Original Issue Discount Securities, we will use the principal amount
       that would be due and payable on the voting date if the Maturity of the
       New Debentures were accelerated to that date because of a default.

     - For New Debentures whose principal amount is not known (for example,
       because it is based on an index), we will use a special rule for that New
       Debentures described in the prospectus supplement.

     - For New Debentures denominated in one or more foreign currencies or
       currency units, we will use the U.S. dollar equivalent.

     New Debentures will not be considered outstanding, and therefore are not
eligible to vote, if we have deposited or set aside in trust for you money for
their payment or redemption. New Debentures will also not be eligible to vote if
they have been fully defeased as described later on page 11 under "Full
Defeasance". (Section 101)

     We generally will be entitled to set any day as a record date for the
purpose of determining the holders of outstanding New Debentures that are
entitled to vote or take other action under the Indenture. In certain limited
circumstances, the Trustee will be entitled to set a record date for action by
holders. If we or the Trustee set a record date for a vote or other action to be
taken by holders of a particular series, that vote or action may be taken only
by persons who are holders of outstanding New Debentures of that series on the
record date and must be taken within 180 days following the record date or a
shorter period that we may specify (or as the Trustee may specify if it sets the
record date). We may shorten or lengthen (but not beyond 180 days) this period
from time to time. (Section 104)

   "STREET NAME" AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS OR
   BROKERS FOR INFORMATION ON HOW APPROVAL MAY BE GRANTED OR DENIED IF WE
   SEEK TO CHANGE THE INDENTURE OR THE DEBT SECURITIES OR REQUEST A WAIVER.

<PAGE>   11

COVENANTS

     The prospectus supplement for your series of New Debentures may set forth
restrictive covenants with respect to your New Debentures.

DEFEASANCE

     The following discussion of full defeasance and covenant defeasance will be
applicable to your series of New Debentures only if we choose to have them apply
to that series. If we do so choose, we will inform you of this decision in the
prospectus supplement. (Section 1301)

     FULL DEFEASANCE.  If there is a change in federal tax law, as described
below, we can legally release ourselves from any payment or other obligations on
the New Debentures (called "FULL DEFEASANCE") if we put in place the following
other arrangements for you to be repaid:

     - We must deposit in trust for your benefit and the benefit of all other
       direct holders of the New Debentures a combination of money and U.S.
       government or U.S. government agency notes or bonds that will generate
       enough cash to make interest, principal and any other payments on the New
       Debentures on their various due dates.

     - There must be a change in current federal tax law or an IRS ruling that
       lets us make the above deposit without causing you to be taxed on the New
       Debentures any differently than if we did not make the deposit and just
       repaid the New Debentures ourselves. (Under current federal tax law, the
       deposit and our legal release from the New Debentures would be treated as
       though we took back your New Debentures and gave you your share of the
       cash and notes or bonds deposited in trust. In that event, you could
       recognize gain or loss on the New Debentures you give back to us.)

     - We must deliver to the Trustee a legal opinion of our counsel confirming
       the tax law change described above. (Sections 1302 and 1304)

     - If we ever did accomplish full defeasance, as described above, you would
       have to rely solely on the trust deposit for repayment on the New
       Debentures. You could not look to us for repayment in the unlikely event
       of any shortfall. Conversely, the trust deposit would most likely be
       protected from claims of our lenders and other creditors if we ever
       become bankrupt or insolvent.

     COVENANT DEFEASANCE.  Under current federal tax law, we can make the same
type of deposit described above and be released from some of the restrictive
covenants in the New Debentures that may be described in the applicable
prospectus supplement. This is called "COVENANT DEFEASANCE". In that event, you
would lose the protection of those restrictive covenants but would gain the
protection of having money and securities set aside in trust to repay the New
Debentures. In order to achieve covenant defeasance, we must do the following:

     - We must deposit in trust for your benefit and the benefit of all other
       direct holders of the New Debentures a combination of money and U.S.
       government or U.S. government agency notes or bonds that will generate
       enough cash to make interest, principal and any other payments on the New
       Debentures on their various due dates.

     - We must deliver to the Trustee a legal opinion of our counsel confirming
       that under current federal income tax law we may make the above deposit
       without causing you to be taxed on the New Debentures any differently
       than if we did not make the deposit and just repaid the New Debentures
       ourselves.

     If we accomplish covenant defeasance, the following provisions of the
Indenture and the New Debentures would no longer apply:

     - Covenants applicable to the series of New Debentures and described in the
       prospectus supplement.

                                        9
<PAGE>   12

     - The Events of Default relating to breach of covenants and acceleration of
       the maturity of other debt, described later under "What Is an Event of
       Default?"

     If we accomplish covenant defeasance, you can still look to us for
repayment of the New Debentures if there is a shortfall in the trust deposit. In
fact, if one of the remaining Events of Default occurs (such as our bankruptcy)
and the New Debentures become immediately due and payable, there may be such a
shortfall. Depending on the event causing the default, you may not be able to
obtain payment of the shortfall. (Sections 1303 and 1304)

EVENTS OF DEFAULT

     You will have special rights if an Event of Default occurs and is not
cured, as described later in this subsection.

     WHAT IS AN EVENT OF DEFAULT?  The term "EVENT OF DEFAULT" for the New
Debentures means any of the following:

     - We do not pay the principal of or any premium on New Debenture on its due
       date.

     - We do not pay interest on New Debenture within 30 days of its due date.

     - We do not deposit any sinking fund payment on its due date.

     - We remain in breach of a covenant of the Indenture for 60 days after we
       receive a notice of default stating we are in breach. The notice must be
       sent by either the Trustee or holders of 10% of the principal amount of
       New Debentures of the affected series.

     - We file for bankruptcy or certain other events in bankruptcy, insolvency
       or reorganization occur.

     - Any other Event of Default described in the prospectus supplement occurs.
       (Section 501)

     REMEDIES IF AN EVENT OF DEFAULT OCCURS. If an Event of Default has occurred
and has not been cured, the Trustee or the holders of 25% in principal amount of
the New Debentures of the affected series may declare the entire principal
amount of all the New Debentures of that series to be due and immediately
payable. If an Event of Default occurs because of certain events in bankruptcy,
insolvency or reorganization, the principal amount of all the New Debentures of
that series will be automatically accelerated, without any action by the Trustee
or any holder. A declaration of acceleration of maturity may be canceled by the
holders of at least a majority in principal amount of the New Debentures of the
affected series. (Section 502)

     Except in cases of default where the Trustee has some special duties, the
Trustee is not required to take any action under the Indenture at the request of
any holders unless the Holders offer the Trustee an indemnity. If reasonable
indemnity is provided, the holders of a majority in principal amount of the
outstanding New Debentures of the relevant series may direct the time, method
and place of conducting any lawsuit or other formal legal action seeking any
remedy available to the Trustee. These majority holders may also direct the
Trustee in performing any other action under the Indenture. (Section 512)

     Before you bypass the Trustee and bring your own lawsuit or other formal
legal action or take other steps to enforce your rights or protect your
interests relating to the New Debentures, the following must occur:

     - You must give the Trustee written notice that an Event of Default has
       occurred and remains uncured.

     - The holders of 25% in principal amount of all outstanding New Debentures
       of the relevant series must make a written request that the Trustee take
       action because of the default, and must offer reasonable indemnity to the
       Trustee against the cost and other liabilities of taking that action.

     - The Trustee must have not taken action for 60 days after receipt of the
       notice and offer of indemnity. (Section 507)

     However, you are entitled at any time to bring a lawsuit for the payment of
money due

                                       10
<PAGE>   13

on your New Debenture on or after its due date. (Section 508)

   "STREET NAME" AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS OR
   BROKERS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A
   REQUEST OF THE TRUSTEE AND TO MAKE OR CANCEL A DECLARATION OF
   ACCELERATION.

     We will furnish to the Trustee every year a written statement of certain of
our officers certifying that to their knowledge we are in compliance with the
Indenture and the New Debentures, or else specifying any default. (Section 1004)

                             REGARDING THE TRUSTEES

     The Trustee under the Mortgage for the New Bonds is HSBC, with whom we
maintain normal banking arrangements. HSBC has also extended a line of credit to
us. We maintain bank accounts, borrow money and have other customary banking
relationships with HSBC in the ordinary course of business.

     The Trustee under the Indenture for the New Debentures is The Bank of New
York, which has extended a line of credit to us and with whom we also maintain
normal banking arrangements.

     If an event of default (or an event that would be an event of default if
the requirements for giving us default notice or for our default having to exist
for a specific period of time were disregarded) occurs, one or both of the
Trustees may be considered to have a conflicting interest for purposes of the
Trust Indenture Act of 1939 with respect to the Securities. In that case, one or
both of the Trustees may be required to resign as trustee and we would be
required to appoint one or more successor trustees.

          DESCRIPTION OF TERMS COMMON TO NEW BONDS AND NEW DEBENTURES

     Unless we provide otherwise in the prospectus supplement, the following
provisions apply equally to, both, New Bonds and New Debentures.

FORM, EXCHANGE AND TRANSFER

     The Securities will be issued:

     - only in fully registered form;

     - without interest coupons; and

     - in denominations that are multiples of $1,000.

     You may have your Securities broken into more Securities of smaller
denominations or combined into fewer Securities of larger denominations, as long
as the total principal amount is not changed. This is called an "EXCHANGE".

     You may exchange or transfer Securities at the office of the entity
performing the role of maintaining the list of registered holders, known as the
"SECURITY REGISTRAR", or at the office of any transfer agent designated by us
for that purpose.

     You will not be required to pay a service charge to transfer or exchange
Securities, but you may be required to pay for any tax or other governmental
charge associated with the exchange or transfer. The transfer or exchange will
only be made if the Security Registrar or transfer agent, as applicable, is
satisfied with your proof of ownership.

     If the Securities are redeemable and we redeem less than all of the
Securities of a particular series, we may block the transfer or exchange of
Securities during the period beginning 15 days before the day we mail the notice
of redemption and ending on the day of that mailing, in order to freeze the list
of holders to

                                       11
<PAGE>   14

prepare the mailing. We may also refuse to register transfers or exchanges of
Securities selected for redemption, except that we will continue to permit
transfers and exchanges of the unredeemed portion of any Securities being
partially redeemed.

PAYMENT AND PAYING AGENTS

     We will pay interest to you if you are a direct holder listed in the
records of the Security Registrar at the close of business on the "REGULAR
RECORD DATE." The prospectus supplement will specify the Regular Record Dates
for the Securities.

     We will pay interest, principal and any other money due on the Securities
at the corporate trust offices of each of the designated Trustees. You must make
arrangements to have your payments picked up or wired from that office. We may
also choose to pay interest by mailing checks.

   "STREET NAME" AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS OR
   BROKERS FOR INFORMATION ON HOW THEY WILL RECEIVE PAYMENTS.

     We may also arrange for additional payment offices and may cancel or change
those offices, including our use of the corporate trust offices of each of the
designated Trustees. These offices are called "PAYING AGENTS". We are required
to maintain a Paying Agent in each Place of Payment for the Securities. We must
notify you of changes in the Paying Agents for the Securities.

LEGAL OWNERSHIP

"STREET NAME" AND OTHER INDIRECT HOLDERS

     Investors who hold Securities in accounts at banks or brokers will
generally not be recognized by us as legal holders of Securities. This is called
holding in "STREET NAME". Instead, we would recognize only the bank or broker,
or the financial institution the bank or broker uses to hold its securities.
These intermediary banks, brokers and other financial institutions pass along
principal, interest and other payments on the securities, either because they
agree to do so in their customer agreements or because they are legally required
to forfeit these securities payments. If your New Securities are in "Street
Name," you should check with your own institution to find out:

     - How it handles securities payments and notices.

     - Whether it imposes fees or charges.

     - How it would handle voting if ever required.

     - Whether and how you can instruct it to send you Debt Securities
       registered in your own name so you can be a direct holder as described
       below.

     - How it would pursue rights under the Debt Securities if there were a
       default or other event triggering the need for holders to act to protect
       their interests.

DIRECT HOLDERS

     Our obligations, as well as the obligations of the Trustee and those of any
third parties employed by us or either Trustee, run only to Persons who are
registered as holders of Securities. As noted above, we do not have obligations
to you if you hold in "Street Name" or other indirect means, either because you
choose to hold Securities in that manner or because the Securities are issued in
the form of Global Securities as described below. For example, once we make
payment to the registered holder, we have no further responsibility for the
payment even if that holder is legally required to pass the payment along to you
as a "Street Name" customer but does not fulfill this obligation.

                                       12
<PAGE>   15

                               GLOBAL SECURITIES

     WHAT IS A GLOBAL SECURITY?  A Global Security is a special type of
indirectly-held Security, as described above under "Street Name' and Other
Indirect Holders". We may choose to issue some or all of the Securities in the
form of Global Securities, in which case the ultimate beneficial owners can only
be indirect holders. We do this by requiring that the Global Security be
registered in the name of a financial institution we select and by requiring
that the Securities included in the Global Security not be transferred to the
name of any other direct holder unless the special circumstances described below
occur. The financial institution that acts as the sole direct holder of the
Global Security is called the "Depositary". Any person wishing to own a Global
Security must do so indirectly through an account with a broker, bank or other
financial institution that in turn has an account with the Depositary. The
prospectus supplement will indicate whether your series of Securities will be
issued only in the form of Global Securities.

     SPECIAL INVESTOR CONSIDERATIONS FOR GLOBAL SECURITIES.  As an indirect
holder, an investor's rights relating to a Global Security will be governed by
the account rules of the investor's financial institution and of the Depositary,
as well as general laws relating to securities transfers. We do not recognize
this type of investor as a holder of Securities and instead deal only with the
Depositary that holds the Global Security.

     An investor should be aware that if Securities are issued only in the form
of Global Securities:

     The investor cannot get Securities registered in his or her own name.

     - The investor cannot receive physical certificates for his or her interest
       in the Securities.

     - The investor will be a "Street Name" holder and must look to his or her
       own bank or broker for payments on the Securities and protection of his
       or her legal rights relating to the Securities. See the discussion above
       "Street Name" and Other Indirect Holders".

     - The Depositary's policies will govern payments, transfers, exchange and
       other matters relating to the investor's interest in the Global Security.
       We and each Trustee have no responsibility for any aspect of the
       Depositary's actions or for its records of ownership interests in the
       Global Security. We and each Trustee also do not supervise the Depositary
       in any way.

     - The laws of some jurisdictions require that certain purchasers receive
       physical certificates for their interests in the securities. These laws
       may impair the ability to transfer beneficial interests in a Global
       Security.

     SPECIAL SITUATIONS WHEN A GLOBAL SECURITY WILL BE TERMINATED.  In a few
special situations described later, a Global Security will terminate and
interests in it will be exchanged for physical certificates representing
Securities. After that exchange, the choice of whether to hold Securities
directly or in "Street Name" will be up to the investor. Investors must consult
their own bank or brokers to find out how to have their interests in Securities
transferred to their own name so that they will be direct holders. The rights of
"Street Name" investors and direct holders in the Securities have been described
above under "Street Name" and Other Indirect Holders" and "Direct Holders" on
page 12.

     The special situations for termination of a Global Security are:

     - When the Depositary notifies us that it is unwilling, unable or no longer
       qualified to continue as Depositary.

     - When an event of default on the Securities has occurred and has not been
       cured. (Defaults are discussed above)

     The prospectus supplement may also list additional situations for

series of Securities covered by the prospectus supplement. When a Global
Security terminates, the Depositary (and not the company or each Trustee) is
responsible for deciding the names of the institutions that will be the initial
direct holders.

                              PLAN OF DISTRIBUTION

     We may sell Securities:

     - to or through underwriting syndicates represented by managing
       underwriters;

     - through one or more underwriters without a syndicate for them to offer
       and sell to the public;

     - through dealers or agents; and

     - to investors directly in negotiated sales or in competitively bid
       transactions.

     Any underwriter or agent involved in the offer and sale of any series of
the Securities will be named in the prospectus supplement.

     The prospectus supplement for each series of Securities will describe:

     - the terms of the offering of these Securities, including the name of the
       agent or the name or names of any underwriters;

     - the public offering or purchase price;

     - any discounts and commissions to be allowed or paid to the agent or
       underwriters and all other items constituting underwriting compensation;

     - any discounts and commissions to be allowed or paid to dealers; and

     - other specific terms of the particular Securities.

     Only the agents or underwriters named in a prospectus supplement are agents
or underwriters in connection with the Securities being offered by that
prospectus supplement.

     Underwriters, agents and dealers may be entitled, under agreements with us,
to indemnification against certain civil liabilities, including liabilities
under the Securities Act.

     Underwriters to whom we sell Securities for public offering and sale are
obliged to purchase all of those particular Securities if any are purchased.
This obligation is subject to certain conditions and may be modified in the
applicable prospectus supplement.

     Underwriters, dealers or agents may engage in transactions with, or perform
services for, us or our affiliates in the ordinary course of business.

                          VALIDITY OF DEBT SECURITIES

     Sullivan & Cromwell, New York, New York, will pass upon the validity of the
Securities for us.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Sections 721 through 726 of the Business Corporation Law of the State of
New York (the "BCL") provide for indemnification of the officers and directors
of Niagara Mohawk Power Corporation (the "Company") under certain conditions and
subject to specific limitations. The BCL permits New York corporations to
supplement the statutory indemnification with additional "non-statutory"
indemnification for directors and officers meeting a specified standard of
conduct and to advance to officers and directors litigation expenses under
certain circumstances. As permitted by the BCL, Article VI of the Company's
By-Laws provides for indemnification of, and advancement of litigation expenses
incurred by, directors and officers of the Company.

     The Company has also obtained insurance providing for indemnification of
directors and officers against certain expenses and liabilities. In addition,
pursuant to a 1986 amendment to the BCL, the Company has entered into agreements
with certain of the officers and directors of the Company providing for
indemnification for the liability of officers and directors not covered by the
policy mentioned above and the Company has agreed to enter into similar
arrangements with its officers who are not directors of the Company. Such
additional indemnification does not cover acts committed in bad faith or acts
which were the result of active and deliberate dishonesty. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or persons controlling the Company pursuant to
the foregoing provisions, the Company has been informed that, in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

     Furthermore, Section 402(b) of the BCL provides that a corporation may
include a provision in its certificate of incorporation limiting the liability
of its directors to the corporation or its shareholders for damages for the
breach of any duty, except for a breach involving intentional misconduct, bad
faith, a knowing violation of law or receipt of an improper personal benefit for
certain illegal dividends, loans or stock repurchases. Article XIIA of the
Certificate of Amendment of the Certificate of Incorporation of the Company
limits, with certain exceptions, the personal liability

                                      II-1
<PAGE>   19

of a director of the Company to the Company or its shareholders for damages for
any breach of duty in such capacity to the fullest extent permitted by the BCL.

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 a 20 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

             (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;

                                      II-5
<PAGE>   23

          PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if
     the registration statement is on Form S-3, Form S-8 or Form F-3 and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in this 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 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 which remain unsold at the
     termination of the offering.

          (4) If the registrant is a foreign private issuer, to file a
     post-effective amendment to the registration statement to include any
     financial statements required by Rule 3-19 of this chapter at the start of
     any delayed offering or throughout a continuous offering. Financial
     statements and information otherwise required by Section 10(a)(3) of the
     Act need not be furnished, provided, that the registrant includes in the
     prospectus, by means of a post-effective amendment, financial statements
     required pursuant to this paragraph (a)(4) and other information necessary
     to ensure that all other information in the prospectus is at least as
     current as the date of those financial statements. Notwithstanding the
     foregoing, with respect to a registration statement of Form F-3, a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or Rule 3-19 of
     this chapter if such financial statements and information are 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 Form F-3.

          (b) 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 that is incorporated by reference in this registration statement
     shall be deemed to be a new registration 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.

          (c) 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, or otherwise, the registrant has been advised 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.

To the Representative(s)
     named in Schedule I hereto
     of the Underwriters named

Dear Ladies and Gentlemen:

                  Niagara Mohawk Power Corporation, a New York corporation (the

(the "Underwriters") for whom you are acting as representatives (the

Underwriters and in the aggregate principal amounts specified in Schedule I
hereto (the "Securities") to be issued under its Mortgage Trust Indenture, dated

(the "Trustee"), as heretofore supplemented and amended by supplemental
indentures and as to be further supplemented and amended by a supplemental

hereinafter referred to as the "Mortgage"), and Schedule I hereto sets forth the
date, time and manner of delivery of the Securities.



<PAGE>   2
                  1. Representations and Warranties by the Company. The Company
represents and warrants to, and agrees with each Underwriter that:

                  (a) The Company meets the requirements for use of Form S-3
         under the Securities Act of 1933, as amended (the "Act") and has filed
         with the Securities and Exchange Commission (the "Commission") a
         registration statement (with the file number set forth on Schedule I
         hereto) on such Form, including a prospectus, for the registration
         under the Act of the Securities, which registration statement has
         become effective. Such registration statement and prospectus may have
         been amended or supplemented from time to time prior to the date of
         this Agreement. Any such amendment or supplement was or will be timely
         filed with the Commission and any such amendment has become effective.
         The Company will file with the Commission a prospectus supplement (the
         "Prospectus Supplement") relating to the Securities pursuant to Rule
         424 under the Act. Copies of such registration statement and
         prospectus, any such amendment or supplement, the Prospectus Supplement
         and all documents incorporated by reference therein which were filed
         with the Commission on or prior to the date of this Agreement have been
         delivered to you. Such registration statement and such prospectus or
         any prospectus used in place thereof pursuant to Rule 429 under the
         Act, as amended or supplemented prior to the date of this Agreement and
         as supplemented by the Prospectus Supplement, are hereinafter called
         the "Registration Statement," and the "Prospectus," respectively. Any
         reference herein to the Registration Statement or the Prospectus shall
         be deemed to refer to and include the documents incorporated by
         reference therein pursuant to Item 12 of Form S-3 which were filed
         under the Securities Exchange Act of 1934 (the "Exchange Act") on or
         before the date of this Agreement, and any reference herein to the
         terms "amend," "amendment" or "supplement" with respect to the
         Registration Statement or the Prospectus shall be deemed to refer to
         and include the filing of any document under the Exchange Act deemed to
         be incorporated by reference therein after the date of this Agreement.

                  (b) (i) The Registration Statement, at the time it became
         effective, any post-effective amendment thereto, at the time it became
         effective, the Prospectus, at the date of this Agreement and at the
         Closing Date (as hereinafter defined), any amendments thereof and
         supplements thereto and the Mortgage complied or will comply in all
         material respects with the Act, the Trust Indenture Act of 1939 (the
         "Trust Indenture Act") and the Exchange Act and the respective rules
         thereunder and (ii) neither the Registration Statement nor the
         Prospectus nor any amendment thereof or supplement thereto contained or
         will contain any untrue statement of a material fact or omitted or will
         omit to state any material fact required to be stated therein or
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading; provided,
         however, that the Company makes no representations or warranties as to
         (A) that part of the


                                        2
<PAGE>   3
         Registration Statement which shall constitute the Statement of
         Eligibility (Form T-1) under the Trust Indenture Act of the Trustee or
         (B) the information contained in or omitted from the Registration
         Statement or the Prospectus or any amendment thereof or supplement
         thereto in reliance upon and in conformity with information furnished
         in writing to the Company by or on behalf of any Underwriter through
         the Representatives expressly for use in the Prospectus as amended or
         supplemented.

                  (c) The documents incorporated by reference in the Prospectus,
         when they were filed with the Commission or became effective, conformed
         in all material respects to the requirements of the Act or the Exchange
         Act and the rules and regulations of the Commission thereunder, and any
         documents so filed and incorporated by reference subsequent to the date
         of this Agreement will, when they are filed with the Commission,
         conform in all material respects to the requirements of the Act and the
         Exchange Act, and the rules and regulations of the Commission
         thereunder, and none of such documents include or will include any
         untrue statement of a material fact or omit or will omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that such representation
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished by an Underwriter through
         the representatives expressly for use in the Prospectus as supplemented
         or amended.

                  (d) The accountants who have certified or shall certify the
         audited financial statements incorporated by reference as parts of the
         Registration Statement and the Prospectus are independent accountants
         as required by the Act and the rules and regulations of the Commission
         thereunder.

                  (e) The financial statements and information included or
         incorporated by reference in the Registration Statement present fairly,
         in all material respects, the financial position, results of operations
         and changes in financial position of the Company at the respective
         dates and for the respective periods indicated, all in conformity with
         generally accepted accounting principles applied on a consistent basis
         throughout the periods involved except as therein stated. The Company
         has no material contingent obligation which is not disclosed in the
         Registration Statement and Prospectus.

                  (f) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, except as
         set forth in the Registration Statement and the Prospectus, there has
         not been any material adverse change in the condition (financial or
         other), earnings, business or


                                        3

         properties of the Company, whether or not arising from transactions in
         the ordinary course of business.

                  (g) The Securities have been duly authorized, and, when are
         issued and delivered pursuant to this Agreement, such securities will
         have been duly executed, authenticated, issued and delivered in
         accordance with the Mortgage and sold to the Underwriters as provided
         herein, will constitute valid and legally binding obligations of the
         Company entitled to the benefits of the Mortgage.

                  (h) The Company has been duly incorporated and validly
         existing corporation in good standing under the laws of the State of
         New York; the Company holds all material licenses, certificates and
         permits from governmental authorities necessary for the conduct of its
         business; and the Company has the corporate power and authority to own
         its properties and conduct its business as described in the Prospectus.

                  (i) Neither the issuance or sale of the Securities, nor the
         consummation of any other of the transactions herein contemplated, nor
         the fulfillment of the terms hereof, will conflict with, result in a
         breach of or constitute a default under the terms of any indenture, or
         other agreement or instrument to which the Company is a party or by
         which it is bound or, to the best knowledge of the Company, any order
         or regulation applicable to the Company of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over the
         Company.

                  (j) The Company has filed a petition with the Public Service
         Commission of the State of New York ("PSC") with respect to the issue
         and sale of the Securities. The PSC has authorized the issue and sale
         thereof but upon the express condition that the Company shall file with
         the PSC for its consideration a copy of this Agreement and a statement
         setting forth (i) the interest rate for the Securities, (ii) any
         initial public offering price thereof, (iii) the price to be paid to
         the Company for the Securities, (iv) any underwriting commissions, (v)
         any sinking fund or other mandatory redemption provisions, and (vi) any
         redemption prices and dates with respect to redemption of the
         Securities at the option of the Company.

                  (k) The Company and each material subsidiary of the Company
         have good and valid title to all or substantially all of their
         permanent fixed properties (including the specified undivided interests
         in generating units and plants referred to in the Prospectus), except
         as otherwise indicated in the Prospectus, subject only to the
         respective liens of the indentures securing its mortgage debt.

                  2. Purchase and Sale. Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to you and each other Underwriter, and you and each other
Underwriter agree, severally and not jointly, to purchase from the Company, at
the purchase price set forth in Schedule I hereto, the respective principal
amounts of the Securities set forth opposite your respective names in Schedule I
hereto and Schedule II hereto and Schedule I hereto sets forth the date, time
and manner of delivery of the Securities.

                  Upon authorization by the Representatives of the release of
the Securities, the several Underwriters propose to offer the Securities for
sale upon the terms and conditions set forth in the Prospectus.

                  3. Delivery and Payment. Delivery of and payment for the
Securities shall be made at the place, date and time specified in Schedule I
hereto. The Securities shall be in definitive form and shall be registered in
such names and in such authorized denominations as the Representatives may
request not less than forty-eight hours in advance of the Closing Date, and
shall be delivered by or on behalf of the Company to the Representatives for the
account of such underwriter, against payment by such underwriter or on its
behalf of the purchase price therefor by wire transfer of federal (same day)
funds to the account specified by the Company to the Representatives at least
forty-eight hours in advance of the Closing Date.

                  4. Agreements. The Company agrees with each of the several
Underwriters that:

                  (a) The Company will cause the Prospectus Supplement to be
         filed or mailed for filing, in a form approved by the Representatives,
         pursuant to Rule 424 under the Act and will notify you promptly of such
         filing or mailing. During the period for which a prospectus relating to
         the Securities is required to be delivered under the Act, the Company
         will promptly advise the Representatives (i) when any amendment to the
         Registration Statement shall have become effective, (ii) when any
         subsequent supplement to the Prospectus has been filed or mailed for
         filing, (iii) of any request by the Commission for any amendment of or
         supplement to the Registration Statement or the Prospectus or for any
         additional information, (iv) of the issuance by the Commission of any
         stop order suspending the effectiveness of the Registration Statement
         or the institution or threatening of any proceedings for that purpose,
         and (v) of the receipt by the Company of any notification with respect
         to the suspension of the qualification of the Securities for sale in
         any jurisdiction or the initiation or threatening of any proceeding for
         such purpose. The Company will not file any amendment to the
         Registration Statement or supplement to the Prospectus (other than any
         prospectus supplement relating to the offering of securities registered
         under the Registration Statement other than the Securities and
         permitted by Section 4(g) hereof, or any document required to


                                        5
<PAGE>   6
         be filed under the Exchange Act which upon filing is deemed to be
         incorporated by reference in the Registration Statement or Prospectus)
         unless the Company has furnished to you a copy for your review prior to
         filing and will not file any such proposed amendment or supplement to
         which you reasonably object after receiving a reasonable notice from
         the Representatives thereof. The Company will furnish to you prior to
         the filing thereof a copy of any such prospectus supplement and any
         document which upon filing is deemed to be incorporated by reference in
         the Registration Statement or Prospectus. The Company will use its best
         efforts to prevent the issuance of any such stop order and, if issued,
         to obtain as soon as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then amended or supplemented
         would include any untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading,
         or if it shall be necessary at any time to amend or supplement the
         Prospectus to comply with the Act or the Exchange Act or the respective
         rules thereunder, the Company promptly will prepare and file with the
         Commission, subject to paragraph (a) of this Section 4, an amendment or
         supplement which will correct such statement or omission or an
         amendment or supplement which will effect such compliance.

                  (c) The Company will make generally available to its security
         holders and to the Representatives as soon as practicable, but in any
         event not later than eighteen months after the effective date of the
         Registration Statement (as defined in Rule 158(c) under the Act), an
         earnings statement (which need not be audited) of the Company, for a
         twelve-month period beginning after the date of the Prospectus
         Supplement filed pursuant to Rule 424 under the Act, which will satisfy
         the provisions of Section 11(a) of the Act.

                  (d) The Company has previously furnished to each of the
         Representatives, upon request, a signed copy of the Registration
         Statement as originally filed and of each amendment thereto, including
         the statement on Form T-1 of the Trustee and all powers of attorney,
         consents and exhibits filed therewith (other than exhibits incorporated
         by reference), and will deliver to the Representatives conformed copies
         of the Registration Statement, the Prospectus (including all documents
         incorporated by reference therein) and, so long as delivery of a
         prospectus by an Underwriter or dealer may be required by the Act, all
         amendments of and supplements to such documents, in each case as soon
         as available and in such quantities as the Representatives may
         reasonably request.


                                        6
<PAGE>   7
                  (e) The Company will furnish such information, execute such
         instruments and take such action as may be required to qualify the
         Securities for sale under the laws of such jurisdictions as the
         Representatives may designate and will maintain such qualifications in
         effect so long as required for the distribution of the Securities;
         provided, however, that the Company shall not be required to qualify to
         do business in any jurisdiction where it is not now so qualified or to
         take any action which would subject it to general or unlimited service
         of process in any jurisdiction where it is not now so subject.

                  (f) So long as the Securities are outstanding, the Company
         will furnish (or cause to be furnished) to each of the Representatives,
         upon request, copies of (i) all reports to stockholders of the Company
         and (ii) all reports and financial statements filed with the Commission
         or any national securities exchange.

                  (g) During the period beginning from the date of this
         Agreement and continuing to and including the earlier of (i) the
         termination of trading restrictions on the Securities, as notified to
         the Company by the Representatives, or (ii) the thirtieth day after the
         Closing Date for the Securities, not to offer, sell, or otherwise
         dispose of any first mortgage bonds of the Company (except under prior
         contractual commitments which have been disclosed to you), without the
         prior written consent of the Representatives, which consent shall not
         be unreasonably withheld.

                  5. Expenses. Whether or not the transactions contemplated
hereunder are consummated or this Agreement is terminated, the Company will pay
all costs and expenses incident to the performance of the obligations of the
Company hereunder, including, without limiting the generality of the foregoing,
all costs, taxes and expenses incident to the issue and delivery of the
Securities to the Underwriters, all fees and expenses of the Company's counsel
and accountants, all costs and expenses incident to the preparing, printing and
filing of the Registration Statement (including all exhibits thereto), the
Prospectus and any amendments thereof or supplements thereto, all costs and
expenses incurred in connection with "blue sky" qualifications, the legality of
the Securities for investment and the rating of the Securities, and all costs
and expenses of the printing and distribution of all documents in connection
with this underwriting. Except as provided in this Section 5 and Section 8
hereof, the Underwriters will pay all their own costs and expenses, including
the fees of their counsel and any advertising expenses in connection with any
offer they may make.

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy in all material respects of the representations and warranties on
the part of the Company contained herein as of the date hereof and the Closing
Date, to the accuracy of the statements of Company officers made in any
certificates given pursuant to the provisions


                                        7
<PAGE>   8
hereof, to the performance by the Company of its obligations hereunder and to
the following additional conditions:

                  (a) No stop order suspending the effectiveness of the
         Registration Statement shall have been issued and no proceedings for
         that purpose shall have been instituted or, to the knowledge of the
         Company or the Representatives, threatened.

                  (b) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's General Counsel to the effect that (i) the
         Company has all requisite corporate power and authority to own or lease
         and operate its properties and to carry on its own business as now
         conducted; (ii) To such counsel's knowledge, no consent, waiver,
         approval, authorization or order of, or filing, registration,
         qualification license or permit of or with, any Federal or New York
         State court or governmental agency, body or administrative agency is
         required for the execution, delivery and performance by the Company of
         the Underwriting Agreement and the Mortgage, the issuance and sale of
         the Securities, and the consummation of the transactions contemplated
         thereby, except (a) such as have been obtained and made under the
         Act and the Trust Indenture Act and from the PSC, or have been obtained
         as described in the Prospectus, (b) such as are required under state
         securities of Blue Sky laws and regulations, and (c) such as to which
         the failure to be obtained or made would not reasonably be expected,
         either individually or in the aggregate, to have a material adverse
         effect on the business, financial condition or results of operations of
         the Company and its subsidiaries, taken as a whole; provided, that
         insofar as performance by the Company of its obligations under the
         Underwriting Agreement, the Mortgage and the Securities is concerned,
         such counsel expresses no opinion as to bankruptcy, insolvency,
         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights; provided further that such
         counsel express no opinion as to any laws, rules, regulations
         applicable to the Company in its capacity as an electric and gas
         utility and as an operator, owner, or operator and owner of nuclear
         powered generating facilities, including the New York Public Service
         Law, the Federal Power Act, the Public Utility Holding Company Act of
         1935 (the "Holding Company Act"), as amended, the Atomic Energy Act of
         1954 (the "AEA") and the rules and regulations of the PSC and, solely
         with respect to jurisdiction granted by the Holding Company Act, the
         Commission, and the Nuclear Regulatory Commission (the "NRC"); and
         (iii) To such counsel's knowledge, there is not action, suit,
         investigation, litigation or proceeding affecting the Company or any of
         its subsidiaries pending or threatened before any court, governmental
         authority, governmental agency, regulatory body or arbitrator that
         would be reasonably likely to have a material adverse effect.

                  (c) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's regulatory counsel to the effect that the PSC
         has approved the Power Choice Settlement, including the MRA, and has
         issued the Financing Order granting consent to the Company's issuance
         and sale of the Securities, subject to the conditions contained in that
         Order. Based upon the Financing Order, the Company does not require
         authorization from the Federal Energy Regulatory Commission to issue
         and sell the Securities as provided for in the Underwriting Agreement
         and the Mortgage. There is not other Federal or New York State
         regulatory regime naming the Company's securities issuances solely in
         its capacity as an electric and gas company under which the Company is
         required to obtain consent and authorization to issue and sell the
         Security in accordance with the Underwriting Agreement and the
         Mortgage.

                  (d) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's nuclear regulatory counsel to the effect that
         the Company's execution of the Underwriting Agreement and the Mortgage
         and the issuance and sale of the Securities would neither contravene
         the AEA nor the regulations of the NRC in 10 Code of Federal
         Regulations, Chapter I, nor would such actions require any application
         for approval by the NRC.

                  (e) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of Sullivan &
         Cromwell, counsel for the Company, to the effect that (i) the Company
         has been duly incorporated and is existing corporation in good standing
         under the laws of the State of New York, with full corporate power and
         authority to own its properties and conduct its business as described
         in the Prospectus; (ii) the Mortgage has been duly authorized executed
         and delivered by the Company and, assuming due authorization, execution
         and delivery thereof by the Trustee, constitutes a valid, binding and
         enforceable instrument, except as may be limited by bankruptcy,
         insolvency, reorganization, moratorium or other similar laws relating
         to or affecting creditors' rights generally from time to time in effect
         and general principles of equity and except that certain laws and
         judicial decisions of the United States and the State of New York may
         limit the remedies provided for in the Mortgage in connection with the
         security provided for therein and, as to nuclear facilities, such
         remedies may also be limited or rendered unavailable by the AEA, as
         amended, and regulations thereunder; (iii) the Securities have been
         duly authorized, executed and issued by the Company and, assuming due
         authentication thereof by the Trustee, and upon payment and delivery in
         accordance with this Agreement, and subject to the qualification in
         (ii) above with respect to the validity, binding effect and
         enforceability of the Mortgage, will constitute valid and binding
         obligations of the Company entitled to the benefit and


                                        9
<PAGE>   10
         the security afforded by the Mortgage; (iv) all regulatory consents,
         authorizations, approvals and filings required to be made or obtained
         by the Company under the Federal laws of the United States and the laws
         of the State of New York for the issuance, sale and delivery of the
         Securities by the Company in accordance with this Agreement have been
         obtained or made (other than any such regulatory consents,
         authorizations, approvals or filings arising out of, relating to, or
         required to be taken pursuant to, those regulatory regimes that govern
         the Company in its capacity as an electric and gas utility and as an
         operator, owner, or operator and owner of nuclear powered generating
         facilities, including the New York Public Service Law, the Federal
         Power Act, the Holding Company Act, the AEA and the rules and
         regulations of the PSC, and, solely with respect to jurisdiction
         granted by the Holding Company Act, the Securities and Exchange
         Commission, and the NRC ("Utility Related Approvals") or any blue sky
         or state securities laws or regulations, as to which such counsel need
         express no opinion); (v) the Mortgage is qualified under the Trust
         Indenture Act; (vii) this Agreement has been duly authorized, executed
         and delivered by the Company; (viii) the Registration Statement, as of
         its effective date and the Prospectus, as of the date of the
         Prospectus, appear on their face to be appropriately responsive in all
         material respects to the requirements of the Act, the Exchange Act and
         the Trust Indenture Act and the rules and regulations of the Commission
         thereunder; (ix) such counsel have no reason to believe that either the
         Registration Statement, as of its effective date, contained any untrue
         statement of a material fact or omitted to state a material fact
         necessary to make the statements therein not misleading or that the
         Prospectus, as of the date of the Prospectus, contained or on the
         Closing Date contains an untrue statement of a material fact or on the
         Closing Date omits to state a material fact necessary to make the
         statements therein, in the light of the circumstance under which they
         were made, not misleading (except for financial statements and other
         financial data included or incorporated by reference therein as to
         which such counsel need express no opinion); and (x) neither the issue
         or sale of the Securities nor the consummation of any other of the
         transactions contemplated by this Agreement will result in a breach by
         the Company of any terms of, or constitute a default under, the
         Certificate of Incorporation, as amended, or By-Laws of the Company or
         any indenture or other agreement or undertaking of the Company known to
         such counsel.

                  (f) The Representatives shall receive from counsel for the
         Underwriters such opinion or opinions dated the Closing Date with
         respect to the validity of the Securities, the Registration Statement,
         the Prospectus and other related matters as the Representatives may
         reasonably require, and the Company shall have furnished to such
         counsel such documents as they reasonably request for the purpose of
         enabling them to pass upon such matters.

                  (g) The Company shall furnish to the Representatives a
         certificate of a Vice President, the Treasurer or the Controller of the
         Company and a Vice President, the Assistant Controller or the Assistant
         Treasurer of the Company, dated the Closing Date, to the effect that
         the signers of such certificate have carefully examined the
         Registration Statement, the Prospectus and this Agreement and that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct on and as of the
                  Closing Date with the same effect as if made on the Closing
                  Date, and the Company has complied with all the agreements and
                  satisfied all the conditions on its part to be performed or
                  satisfied at or prior to the Closing Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued, and no proceedings
                  for that purpose have been instituted, or, to their knowledge,
                  threatened; and

                           (iii) the Registration Statement, as of the later of
                  the date it became effective or the date of filing of the
                  Company's most recent Annual Report on Form 10-K, does not
                  contain any untrue statement of a material fact or omit to
                  state any material fact required to be stated therein or
                  necessary to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading; the
                  Prospectus, including any supplements or amendments thereto
                  and the documents incorporated by reference therein, does not
                  contain any 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, in the light of the
                  circumstances under which they were made, not misleading; and
                  since the effective date of the Registration Statement there
                  has not occurred any event required to be set forth in an
                  amended or supplemented prospectus which has not been so set
                  forth and there has been no document required to be filed
                  under the Exchange Act and the rules and regulations
                  thereunder, which would be deemed to be incorporated by
                  reference in the Prospectus, which has not been so filed.

                  (h) The Representatives (i) shall have received at or prior to
         the time of execution of this Agreement a letter to the Board of
         Directors of the Company dated the date of such delivery and (ii) shall
         receive at the Closing Date, a letter dated the date of delivery
         thereof from the independent accountants of the Company who have
         certified the financial statements of the Company included or
         incorporated by reference in the Registration Statement stating that
         (1) with respect to the Company and its subsidiaries they are
         independent accountants within the meaning of the Act and the
         applicable published rules and regulations


                                       11
<PAGE>   12
         thereunder; (2) in their opinion the unaudited consolidated financial
         statements of the Company and subsidiary companies included or
         incorporated by reference in the Registration Statement and examined by
         such firm comply as to form in all material respects with the
         applicable accounting requirements of the Act and the published rules
         and regulations thereunder; (3) on the basis of the following
         procedures (but not an examination in accordance with generally
         accepted auditing standards a reading of the minutes of meetings of the
         Board of Directors and stockholders of the Company and its subsidiaries
         since the date of the last audited Balance Sheet as set forth in the
         minute books through a specified date not more than five business days
         prior to the date of delivery of such letter, (B) performance of the
         procedures specified by the American Institute of Certified Public
         Accountants for a review of interim financial information as described
         in SAS 71, Interim Financial Information, on the unaudited condensed
         consolidated interim financial statements of the Company and its
         subsidiaries as incorporated by reference in the Registration Statement
         and the Prospectus, (C) if applicable, a reading of the latest
         available unaudited interim financial data, and (D) inquiries of
         certain officials of the Company who have responsibility for financial
         and accounting matters, nothing has come to their attention which
         caused them to believe that (I) the unaudited condensed consolidated
         interim financial statements, incorporated by reference in the
         Registration Statement and the Prospectus, do not comply as to form in
         all material respects with the applicable accounting requirements of
         the Act and the published rules and regulations thereunder; (II) any
         material modifications should be made to the unaudited condensed
         consolidated interim financial statements, incorporated by reference in
         the Registration Statement and the Prospectus, for them to be in
         conformity with generally accepted accounting principles; and (III) on
         the basis of inquiries of certain officials of the Company who have
         responsibilities for financial and accounting matters and a reading of
         the minutes as stated above, nothing has come to their attention which
         caused them to believe that there was any change at the date of the
         latest available interim financial data and at a specified date not
         more than five business days prior to the date of delivery of such
         letter in the capital stock, other than changes arising as a result of
         sales of Common Stock under the Company's Dividend Reinvestment and
         Stock Purchase Plan and Employee Savings Fund Plan, or long-term debt
         of the Company and its consolidated subsidiaries as compared with
         amounts shown on the latest balance sheet included or incorporated by
         reference in the Registration Statement, or for the period from the
         date of the Company's latest balance sheet included or incorporated by
         reference in the Registration Statement to the end of the preceding
         calendar month for which balance sheet data is available, there were
         any decreases, as compared with the corresponding period in the
         preceding year, in consolidated operating revenues or net income, or
         any decreases in unconsolidated capitalization, as compared with
         amounts shown on the latest balance sheet included or incorporated by
         reference in the Registration Statement, except in all instances for


                                       12
<PAGE>   13
         changes or decreases which the Registration Statement discloses have
         occurred or may occur. The letters of such independent accountants also
         shall be to the effect that they have carried out certain specified
         procedures, not constituting an audit, with respect to certain amounts,
         percentages and financial information which are derived from the
         general accounting records of the Company, which appear or are
         incorporated by reference in the Registration Statement and Prospectus
         and which are specified by the Representatives, and have compared such
         amounts, percentages and financial information with the accounting
         records of the Company and have found them to be in agreement.

                  (i) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, there shall
         not have been any change or decrease specified in the letter or letters
         referred to in paragraph (e) of this Section 6 which makes it
         impractical or inadvisable in the judgment of the Representatives to
         proceed with the public offering or the delivery of the Securities as
         contemplated by the Prospectus.

                  (j) Prior to the Closing Date, the Company shall furnish to
         the Representatives such further information, certificates and
         documents as they may reasonably request.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled when and as required by this Agreement, or if any of the
opinions and certificates mentioned above or elsewhere in this Agreement shall
not be in all material respects satisfactory in form and substance to the
Representatives and their counsel, this Agreement and all obligations of the
Underwriters hereunder may be canceled at, or at any time prior to, the Closing
Date by the Representatives. Notice of such cancellation shall be given to the
Company in writing, or by telephone or telegraph confirmed in writing.

                  7. Conditions of Company's Obligations. The obligations of the
Company to sell and deliver the Securities are subject to the following
conditions:

                  (a) Prior to the Closing Date, no stop order suspending the
         effectiveness of the Registration Statement shall have been issued and
         no proceedings for that purpose shall have been instituted or, to the
         knowledge of the Company or the Representatives, threatened.

                  (b) The PSC shall have granted authorization, and on the
         Closing Date such authorization shall be in full force and effect,
         permitting the issuance and sale of the Securities upon the terms and
         conditions hereunder set forth or contemplated and containing no
         provision unacceptable to the Company.


                                       13
<PAGE>   14
                  (c) The Underwriters shall have furnished to the Company
         completed underwriters' questionnaires from each underwriter named in
         Schedule II hereto, in form and substance satisfactory to counsel for
         the Company, which disclose no relationship between any such
         underwriter, or its directors, officers or partners, and the Company or
         the Trustee, or the directors, officers or partners thereof, which
         would require, in the opinion of such counsel, an amendment of the
         Statement of Eligibility under the Trust Indenture Act on Form T-l
         filed by the Trustee and disqualification of the Trustee.

                  If any of the conditions specified in this Section 7 shall not
have been fulfilled, this Agreement and all obligations of the Company hereunder
may be canceled on or at any time prior to the Closing Date by the Company.
Notice of such cancellation shall be given to the Underwriters in writing or by
telephone or telegraph confirmed in writing.

                  8. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
or because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof, other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally upon demand for all out-of-pocket expenses (including
fees and disbursements of counsel not to exceed $30,000) that shall have been
reasonably incurred by them in connection with the proposed purchase and sale of
the Securities.

                  9. Indemnification. (a) The Company agrees to indemnify and
hold harmless each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the
Prospectus or in any amendment thereof 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, in
the light of the circumstances under which they were made, not misleading, and
agrees to reimburse each such indemnified party for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
Company will 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 any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in


                                       14
<PAGE>   15
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for use in connection
with the preparation thereof; and provided, further, that such indemnity with
respect to a prospectus included in the Registration Statement or any amendment
thereto prior to the supplementing thereof with the Prospectus Supplement shall
not inure to the benefit of any Underwriter (or any person controlling such
Underwriter) from whom the person asserting any such loss, claim, damage or
liability purchased the Securities which are the subject thereof if such person
did not receive a copy of the Prospectus as amended or supplemented (but without
the documents incorporated by reference therein) at or prior to the confirmation
of the sale of such Securities to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact
contained in the Prospectus was corrected in the Prospectus as amended or
supplemented. This indemnity agreement will be in addition to any liability
which the Company may otherwise have.

                  (b) Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who has signed
the Registration Statement and each person, if any, who controls the Company
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from the Company to the Underwriters but only with
reference to written information furnished to the Company by or on behalf of
such Underwriter through the Representatives specifically for use in the
preparation of the documents referred to in the foregoing indemnity, and agrees
to reimburse each such indemnified party for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action. This indemnity agreement will be
in addition to any liability which any Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 9, notify the indemnifying party in writing of the
commencement thereof; but the omission to so notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 9. In case any such action is brought against
any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein, and, to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel satisfactory to
such indemnified party; provided, however, if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, the indemnified
party, or parties shall have the right to select separate counsel to assume such
legal defenses and to


                                       15
<PAGE>   16
otherwise participate in the defense of such action on behalf of such
indemnified party or parties. Upon receipt of notice from the indemnifying party
to such indemnified party of its election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 9 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in connection with the assertion of legal defenses in
accordance with the proviso to the next preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel, approved by the Representatives in the case of
subparagraph (a), representing the indemnified parties under subparagraphs (a)
or (b), as the case may be, who are parties to such action), (ii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party; and except that, if clause (i) or (iii) is applicable,
such liability shall be only in respect of the counsel referred to in such
clause (i) or (iii). In any case to which an exception set forth in (i), (ii) or
(iii) above applies, the fees and expenses of counsel shall be at the expense of
the indemnifying party.

                  (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in subparagraph (a) is
due in accordance with its terms but is for any reason unavailable from the
Company or insufficient to hold the Underwriters harmless in respect of any
losses claims, damages or liabilities (or actions in respect thereof) referred
to therein, the Company and the Underwriters shall contribute to the aggregate
losses, claims, damages and liabilities (or actions in respect thereof) to which
the Company and one or more of the Underwriters may be subject, 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 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 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 the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The relative benefits received by the Company on the one hand and the
Underwriters on the other shall be deemed to be in the same proportion as the
total net proceeds from the offering of the Securities (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters with respect to the offering of the
Securities, in each case as set forth in the table on the cover page of the
Prospectus Supplement. Notwithstanding the foregoing, no


                                       16
<PAGE>   17
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Company and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
subparagraph (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 subparagraph (d). The amount paid or payable by a
party entitled to contribution as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this
subparagraph (d) shall be deemed to include any legal or other expenses
reasonably incurred by such party in connection with investigating or defending
any such action or claim. The Underwriters' obligations under this subparagraph
(d) are several in proportion to their respective underwriting obligations and
not joint. For purposes of this subparagraph (d), each person, if any, who
controls an Underwriter within the meaning of either the Act or the Exchange Act
shall have the same rights to contribution as such Underwriter, and each person,
if any, who controls the Company within the meaning of either the Act or the
Exchange Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject to the fourth sentence of this subparagraph
(d).

                  10. Default by an Underwriter. If any one or more of the
Underwriters shall fail to purchase and pay for all of the Securities agreed to
be purchased by such Underwriter or Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the amount
of Securities set forth opposite their names in Schedule II hereto bears to the
aggregate amount of Securities set forth opposite the names of all the remaining
Underwriters) the Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase; provided, however, that in the event that the
aggregate amount of Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase shall exceed l0% of the aggregate amount of
Securities set forth in Schedule II hereto, the remaining Underwriters shall
have the right to purchase all, but shall not be under any obligation to
purchase any of, the Securities, and if such nondefaulting Underwriters do not
purchase all of the Securities, this Agreement will terminate without liability
on the part of any nondefaulting Underwriter or the Company. In the event of a
default by any Underwriter, as set forth in this Section 10, the Closing Date
shall be postponed for such period, not exceeding seven days, as the
Representatives shall determine in order that the required changes in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. Nothing herein contained shall relieve any
defaulting Underwriter of its liability, if any, to the Company or any
nondefaulting Underwriter for damages occasioned by its default hereunder.


                                       17
<PAGE>   18
                  11. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for all Securities, (a) if prior
to such time trading in securities generally on the New York Stock Exchange
shall have been suspended or limited or minimum prices shall have been
established, or (b) if a banking moratorium shall have been declared either by
Federal or New York State authorities, or (c) if trading in any securities of
the Company shall have been suspended or halted, or (d) if there shall have
occurred any new outbreak or material escalation of hostilities or other
calamity or crisis the effect of which on the financial markets in the United
States is such as to make it, in the judgment of the Representatives,
impracticable or inadvisable to market the Securities or to enforce contracts
for the sale of the Securities.

                  12. Representations and Indemnities to Survive Delivery. The
respective agreements, representations, warranties, indemnities and other
statements of the Company or its officers and of the Underwriters set forth in
or made pursuant to this Agreement will remain in full force and effect,
regardless of any investigation made by or on behalf of any Underwriter or the
Company or any of its officers or directors or any controlling person within the
meaning of the Act, and will survive delivery of and payment for the Securities.
The provisions of Sections 5, 8 and 9 hereof shall survive the termination or
cancellation of this Agreement.

                  13. Notices. All communications hereunder will be in writing
and, if sent to the Representatives, will be mailed, delivered or telegraphed
and confirmed to them at their address set forth for that purpose in Schedule I
hereto or, if sent to the Company, will be mailed, delivered or telegraphed and
confirmed to it at 300 Erie Boulevard West, Syracuse, New York 13202, attention
of [ ], Vice President -- Law and General Counsel.

                  14. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 9 hereof,
and no other person will have any right or obligation hereunder.

                  15. Applicable Law. This Agreement will be governed by and
construed in accordance with the internal substantive laws and not the choice of
law rules of the State of New York.

                  16. Counterparts. This Agreement may be executed in
counterparts, all of which, taken together, shall constitute a single agreement
among the parties to such counterparts.

                  17. Representation of the Underwriters. The Representatives
represent and warrant to the Company that they are authorized to act as the
representatives of the


                                       18
<PAGE>   19
Underwriters in connection with this financing and that the execution and
delivery of this Agreement and any action under this Agreement taken by such
Representatives will be binding upon all Underwriters.

                  18. Interpretation When No Representatives. In the event no
Underwriters are named in Schedule II hereto, the term "Underwriters" shall be
deemed for all purposes of this Agreement to be the Underwriter or Underwriters
named as such in Schedule I hereto, the principal amount of the Securities to be
purchased by any such Underwriter shall refer to that set opposite its name in
Schedule I hereto and all references to the "Representatives" shall be deemed to
refer to the Underwriter or Underwriters named in Schedule I.

                  If the foregoing is in accordance with your understanding of
our agreement, kindly sign and return to us the enclosed duplicate hereof,
whereupon this letter and your acceptance shall represent a binding agreement
among the Company and the several Underwriters in accordance with its terms.

                                            Very truly yours,

                                                              [Date]



To the Representative(s)
     named in Schedule I hereto

Dear Ladies and Gentlemen:

                  Niagara Mohawk Power Corporation, a New York corporation (the
"Company"), proposes to sell to the underwriters named in Schedule II hereto
(the "Underwriters") for whom you are acting as representatives (the
"Representatives"), its Senior Debt Securities of the designations, with the
terms, the initial public offering price, the purchase prices to the
Underwriters and in the aggregate principal amounts specified in Schedule I
hereto (the "Securities") to be issued under its Indenture, dated as of
_________, 2000, from the Company to The Bank of New York (the "Trustee"), as to
be further supplemented and amended by a supplemental indenture relating to the
Securities (such Indenture as so supplemented and amended and as to be so

                  1. Representations and Warranties by the Company. The Company
represents and warrants to, and agrees with each Underwriter that:

                  (a) The Company meets the requirements for use of Form S-3
         under the Securities Act of 1933, as amended (the "Act") and has filed
         with the Securities and Exchange Commission (the "Commission") a
         registration statement (with the file number set forth on Schedule I
         hereto) on such Form, including a prospectus, for the registration
         under the Act of the Securities, which registration statement has
         become effective. Such registration statement and prospectus may have
         been amended or supplemented from time to time prior to the date of
         this Agreement. Any such amendment or supplement was or will be timely
         filed with the Commission and any such amendment has become effective.
         The Company will file with the Commission a prospectus supplement (the
         "Prospectus Supplement") relating to the Securities pursuant to Rule
         424 under the Act. Copies of such registration statement and
         prospectus, any such amendment or supplement, the Prospectus Supplement
         and all documents incorporated by reference therein which were filed
         with the Commission on or prior to the date of this Agreement have been
         delivered to you. Such registration statement and such prospectus or
         any prospectus used in place thereof pursuant to Rule 429 under the
         Act, as amended or supplemented prior to the date of this Agreement and
         as supplemented by the Prospectus Supplement, are hereinafter called
         the "Registration Statement," and the "Prospectus," respectively. Any
         reference herein to the Registration Statement or the Prospectus shall
         be deemed to refer to and include the documents incorporated by
         reference therein pursuant to Item 12 of Form S-3 which were filed
         under the Securities Exchange Act of 1934 (the "Exchange Act") on or
         before the date of this Agreement, and any reference herein to the
         terms "amend," "amendment" or "supplement" with respect to the
         Registration Statement or the Prospectus shall be deemed to refer to
         and include the filing of any document under the Exchange Act deemed to
         be incorporated by reference therein after the date of this Agreement.

                  (b) (i) The Registration Statement, at the time it became
         effective, any post-effective amendment thereto, at the time it became
         effective, the Prospectus, at the date of this Agreement and at the
         Closing Date (as hereinafter defined), any amendments thereof and
         supplements thereto and the Indenture complied or will comply in all
         material respects with the Act, the Trust Indenture Act of 1939 (the
         "Trust Indenture Act") and the Exchange Act and the respective rules
         thereunder and (ii) neither the Registration Statement nor the
         Prospectus nor any amendment thereof or supplement thereto contained or
         will contain any untrue statement of a material fact or omitted or will
         omit to state any material fact required to be stated therein or
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading; provided,
         however,
                                        2
<PAGE>   3
         that the Company makes no representations or warranties as to (A) that
         part of the Registration Statement which shall constitute the Statement
         of Eligibility (Form T-1) under the Trust Indenture Act of the Trustee
         or (B) the information contained in or omitted from the Registration
         Statement or the Prospectus or any amendment thereof or supplement
         thereto in reliance upon and in conformity with information furnished
         in writing to the Company by or on behalf of any Underwriter through
         the Representatives expressly for use in the Prospectus as amended or
         supplemented.

                  (c) The documents incorporated by reference in the Prospectus,
         when they were filed with the Commission or became effective, conformed
         in all material respects to the requirements of the Act or the Exchange
         Act and the rules and regulations of the Commission thereunder, and any
         documents so filed and incorporated by reference subsequent to the date
         of this Agreement will, when they are filed with the Commission,
         conform in all material respects to the requirements of the Act and the
         Exchange Act, and the rules and regulations of the Commission
         thereunder, and none of such documents include or will include any
         untrue statement of a material fact or omit or will omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that such representation
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished by an Underwriter through
         the representatives expressly for use in the Prospectus as supplemented
         or amended.

                  (d) The accountants who have certified or shall certify the
         audited financial statements incorporated by reference as parts of the
         Registration Statement and the Prospectus are independent accountants
         as required by the Act and the rules and regulations of the Commission
         thereunder.

                  (e) The financial statements and information included or
         incorporated by reference in the Registration Statement present fairly,
         in all material respects, the financial position, results of operations
         and changes in financial position of the Company at the respective
         dates and for the respective periods indicated, all in conformity with
         generally accepted accounting principles applied on a consistent basis
         throughout the periods involved except as therein stated. The Company
         has no material contingent obligation which is not disclosed in the
         Registration Statement and Prospectus.

                  (f) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, except as
         set forth in the Registration Statement and the Prospectus, there has
         not been any material

                                        3
<PAGE>   4
         adverse change in the condition (financial or other), earnings,
         business or properties of the Company, whether or not arising from
         transactions in the ordinary course of business.

                  (g) The Securities have been duly authorized, and, when are
         issued and delivered pursuant to this Agreement, such securities will
         have been duly executed, authenticated, issued and delivered in
         accordance with the Indenture and sold to the Underwriters as provided
         herein, will constitute valid and legally binding obligations of the
         Company entitled to the benefits of the Indenture.

                  (h) The Company has been duly incorporated and validly
         existing corporation in good standing under the laws of the State of
         New York; the Company holds all material licenses, certificates and
         permits from governmental authorities necessary for the conduct of its
         business; and the Company has the corporate power and authority to own
         its properties and conduct its business as described in the Prospectus.

                  (i) Neither the issuance or sale of the Securities, nor the
         consummation of any other of the transactions herein contemplated, nor
         the fulfillment of the terms hereof, will conflict with, result in a
         breach of or constitute a default under the terms of any indenture, or
         other agreement or instrument to which the Company is a party or by
         which it is bound or, to the best knowledge of the Company, any order
         or regulation applicable to the Company of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over the
         Company.

                  (j) The Company has filed a petition with the Public Service
         Commission of the State of New York ("PSC") with respect to the issue
         and sale of the Securities. The PSC has authorized the issue and sale
         thereof but upon the express condition that the Company shall file with
         the PSC for its consideration a copy of this Agreement and a statement
         setting forth (i) the interest rate for the Securities, (ii) any
         initial public offering price thereof, (iii) the price to be paid to
         the Company for the Securities, (iv) any underwriting commissions, (v)
         any sinking fund or other mandatory redemption provisions, and (vi) any
         redemption prices and dates with respect to redemption of the
         Securities at the option of the Company.

                  (k) The Company and each material subsidiary of the Company
         have good and valid title to all or substantially all of their
         permanent fixed properties (including the specified undivided interests
         in generating units and plants referred to in the Prospectus), except
         as otherwise indicated in the Prospectus, subject only to the
         respective liens of the indentures securing its mortgage debt.

                  2. Purchase and Sale. Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to you and each other Underwriter, and you and each other
Underwriter agree, severally and not jointly, to purchase from the Company, at
the purchase price set forth in Schedule I hereto, the respective principal
amounts of the Securities set forth opposite your respective names in Schedule I
hereto and Schedule II hereto and Schedule I hereto sets forth the date, time
and manner of delivery of the Securities.

                  Upon authorization by the Representatives of the release of
the Securities, the several Underwriters propose to offer the Securities for
sale upon the terms and conditions set forth in the Prospectus.

                  3. Delivery and Payment. Delivery of and payment for the
Securities shall be made at the place, date and time specified in Schedule I
hereto. The Securities shall be in definitive form and shall be registered in
such names and in such authorized denominations as the Representatives may
request not less than forty-eight hours in advance of the Closing Date, and
shall be delivered by or on behalf of the Company to the Representatives for the
account of such underwriter, against payment by such underwriter or on its
behalf of the purchase price therefor by wire transfer of federal (same day)
funds to the account specified by the Company to the Representatives at least
forty-eight hours in advance of the Closing Date.

                  4. Agreements. The Company agrees with each of the several
Underwriters that:

                  (a) The Company will cause the Prospectus Supplement to be
         filed or mailed for filing, in a form approved by the Representatives,
         pursuant to Rule 424 under the Act and will notify you promptly of such
         filing or mailing. During the period for which a prospectus relating to
         the Securities is required to be delivered under the Act, the Company
         will promptly advise the Representatives (i) when any amendment to the
         Registration Statement shall have become effective, (ii) when any
         subsequent supplement to the Prospectus has been filed or mailed for
         filing, (iii) of any request by the Commission for any amendment of or
         supplement to the Registration Statement or the Prospectus or for any
         additional information, (iv) of the issuance by the Commission of any
         stop order suspending the effectiveness of the Registration Statement
         or the institution or threatening of any proceedings for that purpose,
         and (v) of the receipt by the Company of any notification with respect
         to the suspension of the qualification of the Securities for sale in
         any jurisdiction or the initiation or threatening of any proceeding for
         such purpose. The Company will not file any amendment to the
         Registration Statement or supplement to the Prospectus (other than any
         prospectus supplement relating to the offering of securities registered
         under the Registration Statement


                                        5
<PAGE>   6
         other than the Securities and permitted by Section 4(g) hereof, or any
         document required to be filed under the Exchange Act which upon filing
         is deemed to be incorporated by reference in the Registration Statement
         or Prospectus) unless the Company has furnished to you a copy for your
         review prior to filing and will not file any such proposed amendment or
         supplement to which you reasonably object after receiving a reasonable
         notice from the Representatives thereof. The Company will furnish to
         you prior to the filing thereof a copy of any such prospectus
         supplement and any document which upon filing is deemed to be
         incorporated by reference in the Registration Statement or Prospectus.
         The Company will use its best efforts to prevent the issuance of any
         such stop order and, if issued, to obtain as soon as possible the
         withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then amended or supplemented
         would include any untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading,
         or if it shall be necessary at any time to amend or supplement the
         Prospectus to comply with the Act or the Exchange Act or the respective
         rules thereunder, the Company promptly will prepare and file with the
         Commission, subject to paragraph (a) of this Section 4, an amendment or
         supplement which will correct such statement or omission or an
         amendment or supplement which will effect such compliance.

                  (c) The Company will make generally available to its security
         holders and to the Representatives as soon as practicable, but in any
         event not later than eighteen months after the effective date of the
         Registration Statement (as defined in Rule 158(c) under the Act), an
         earnings statement (which need not be audited) of the Company, for a
         twelve-month period beginning after the date of the Prospectus
         Supplement filed pursuant to Rule 424 under the Act, which will satisfy
         the provisions of Section 11(a) of the Act.

                  (d) The Company has previously furnished to each of the
         Representatives, upon request, a signed copy of the Registration
         Statement as originally filed and of each amendment thereto, including
         the statement on Form T-1 of the Trustee and all powers of attorney,
         consents and exhibits filed therewith (other than exhibits incorporated
         by reference), and will deliver to the Representatives conformed copies
         of the Registration Statement, the Prospectus (including all documents
         incorporated by reference therein) and, so long as delivery of a
         prospectus by an Underwriter or dealer may be required by the Act, all
         amendments of and supplements to such documents, in each case as soon
         as available and in such quantities as the Representatives may
         reasonably request.


                                        6
<PAGE>   7
                  (e) The Company will furnish such information, execute such
         instruments and take such action as may be required to qualify the
         Securities for sale under the laws of such jurisdictions as the
         Representatives may designate and will maintain such qualifications in
         effect so long as required for the distribution of the Securities;
         provided, however, that the Company shall not be required to qualify to
         do business in any jurisdiction where it is not now so qualified or to
         take any action which would subject it to general or unlimited service
         of process in any jurisdiction where it is not now so subject.

                  (f) So long as the Securities are outstanding, the Company
         will furnish (or cause to be furnished) to each of the Representatives,
         upon request, copies of (i) all reports to stockholders of the Company
         and (ii) all reports and financial statements filed with the Commission
         or any national securities exchange.

                  (g) During the period beginning from the date of this
         Agreement and continuing to and including the earlier of (i) the
         termination of trading restrictions on the Securities, as notified to
         the Company by the Representatives, or (ii) the thirtieth day after the
         Closing Date for the Securities, not to offer, sell, or otherwise
         dispose of any debt securities of the Company (except under prior
         contractual commitments which have been disclosed to you), without the
         prior written consent of the Representatives, which consent shall not
         be unreasonably withheld.

                  5. Expenses. Whether or not the transactions contemplated
hereunder are consummated or this Agreement is terminated, the Company will pay
all costs and expenses incident to the performance of the obligations of the
Company hereunder, including, without limiting the generality of the foregoing,
all costs, taxes and expenses incident to the issue and delivery of the
Securities to the Underwriters, all fees and expenses of the Company's counsel
and accountants, all costs and expenses incident to the preparing, printing and
filing of the Registration Statement (including all exhibits thereto), the
Prospectus and any amendments thereof or supplements thereto, all costs and
expenses incurred in connection with "blue sky" qualifications, the legality of
the Securities for investment and the rating of the Securities, and all costs
and expenses of the printing and distribution of all documents in connection
with this underwriting. Except as provided in this Section 5 and Section 8
hereof, the Underwriters will pay all their own costs and expenses, including
the fees of their counsel and any advertising expenses in connection with any
offer they may make.

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy in all material respects of the representations and warranties on
the part of the Company contained herein as of the date hereof and the Closing
Date, to the accuracy of the


                                        7
<PAGE>   8
statements of Company officers made in any certificates given pursuant to the
provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

                  (a) No stop order suspending the effectiveness of the
         Registration Statement shall have been issued and no proceedings for
         that purpose shall have been instituted or, to the knowledge of the
         Company or the Representatives, threatened.

                  (b) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's General Counsel to the effect that (i) the
         Company has all requisite corporate power and authority to own or lease
         and operate its properties and to carry on its own business as now
         conducted; (ii) To such counsel's knowledge, no consent, waiver,
         approval, authorization or order of, or filing, registration,
         qualification license or permit of or with, any Federal or New York
         State court or governmental agency, body or administrative agency is
         required for the execution, delivery and performance by the Company of
         the Underwriting Agreement and the Indenture, the issuance and sale of
         the Securities, and the consummation of the transactions contemplated
         thereby, except (a) such as have been obtained and made under the
         Securities Act and the Trust Indenture Act and from the PSC, or have
         been obtained as described in the Prospectus, (b) such as are required
         under state securities of Blue Sky laws and regulations, and (c) such
         as to which the failure to be obtained or made would not reasonably be
         expected, either individually or in the aggregate, to have a material
         adverse effect on the business, financial condition or results of
         operations of the Company and its subsidiaries, taken as a whole;
         provided, that insofar as performance by the Company of its obligations
         under the Underwriting Agreement, the Indenture and the Securities is
         concerned, such counsel expresses no opinion as to bankruptcy,
         insolvency, reorganization, moratorium and similar laws of general
         applicability relating to or affecting creditors' rights; provided
         further that such counsel express no opinion as to any laws, rules,
         regulations applicable to the Company in its capacity as an electric
         and gas utility and as an operator, owner, or operator and owner of
         nuclear powered generating facilities, including the New York Public
         Service Law, the Federal Power Act, the Public Utility Holding Company
         Act of 1935 (the "Holding Company Act"), as amended, the Atomic Energy
         Act of 1954 (the "AEA") and the rules and regulations of the PSC and,
         solely with respect to jurisdiction granted by the Holding Company Act,
         the Commission, and the Nuclear Regulatory Commission (the "NRC"); and
         (iii) To such counsel's knowledge, there is not action, suit,
         investigation, litigation or proceeding affecting the Company or any of
         its subsidiaries pending or threatened before any court,


                                        8
<PAGE>   9
         governmental authority, governmental agency, regulatory body or
         arbitrator that would be reasonably likely to have a material adverse
         effect.

                  (c) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's regulatory counsel to the effect that the PSC
         has approved the Power Choice Settlement, including the MRA, and has
         issued the Financing Order granting consent to the Company's issuance
         and sale of the Securities, subject to the conditions contained in that
         Order. Based upon the Financing Order, the Company does not require
         authorization from the Federal Energy Regulatory Commission to issue
         and sell the Securities as provided for in the Underwriting Agreement
         and the Indenture. There is not other Federal or New York State
         regulatory regime naming the Company's securities issuances solely in
         its capacity as an electric and gas company under which the Company is
         required to obtain consent and authorization to issue and sell the
         Security in accordance with the Underwriting Agreement and the
         Indenture.

                  (d) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of
         __________, the Company's nuclear regulatory counsel to the effect that
         the Company's execution of the Underwriting Agreement and the Indenture
         and the issuance and sale of the Securities would neither contravene
         the AEA nor the regulations of the NRC in 10 Code of Federal
         Regulations, Chapter I, nor would such actions require any application
         for approval by the NRC.

                  (e) The Company shall furnish to the Representatives opinions,
         addressed to the Underwriters and dated the Closing Date, of Sullivan &
         Cromwell, counsel for the Company, to the effect that (i) the Company
         has been duly incorporated and is existing corporation in good standing
         under the laws of the State of New York, with full corporate power and
         authority to own its properties and conduct its business as described
         in the Prospectus; (ii) the Indenture has been duly authorized executed
         and delivered by the Company and, assuming due authorization, execution
         and delivery thereof by the Trustee, constitutes a valid, binding and
         enforceable instrument, except as may be limited by bankruptcy,
         insolvency, reorganization, moratorium or other similar laws relating
         to or affecting creditors' rights generally from time to time in effect
         and general principles of equity and except that certain laws and
         judicial decisions of the United States and the State of New York may
         limit the remedies provided for in the Indenture in connection with the
         security provided for therein and, as to nuclear facilities, such
         remedies may also be limited or rendered unavailable by the AEA, as
         amended, and regulations thereunder; (iii) the Securities have been
         duly authorized, executed and issued by the Company and, assuming due
         authentication thereof by the Trustee, and upon payment and delivery in


                                        9
<PAGE>   10
         accordance with this Agreement, and subject to the qualification in
         (ii) above with respect to the validity, binding effect and
         enforceability of the Indenture, will constitute valid and binding
         obligations of the Company entitled to the benefit and the security
         afforded by the Indenture; (iv) all regulatory consents,
         authorizations, approvals and filings required to be made or obtained
         by the Company under the Federal laws of the United States and the laws
         of the State of New York for the issuance, sale and delivery of the
         Securities by the Company in accordance with this Agreement have been
         obtained or made (other than any such regulatory consents,
         authorizations, approvals or filings arising out of, relating to, or
         required to be taken pursuant to, those regulatory regimes that govern
         the Company in its capacity as an electric and gas utility and as an
         operator, owner, or operator and owner of nuclear powered generating
         facilities, including the New York Public Service Law, the Federal
         Power Act, the Holding Company Act, the AEA and the rules and
         regulations of the PSC, and, solely with respect to jurisdiction
         granted by the Holding Company Act, the Securities and Exchange
         Commission, and the NRC ("Utility Related Approvals") or any blue sky
         or state securities laws or regulations, as to which such counsel need
         express no opinion); (v) the Indenture is qualified under the Trust
         Indenture Act; (vii) this Agreement has been duly authorized, executed
         and delivered by the Company; (viii) the Registration Statement, as of
         its effective date and the Prospectus, as of the date of the
         Prospectus, appear on their face to be appropriately responsive in all
         material respects to the requirements of the Act, the Exchange Act and
         the Trust Indenture Act and the rules and regulations of the Commission
         thereunder; (ix) such counsel have no reason to believe that either the
         Registration Statement, as of its effective date, contained any untrue
         statement of a material fact or omitted to state a material fact
         necessary to make the statements therein not misleading or that the
         Prospectus, as of the date of the Prospectus, contained or on the
         Closing Date contains an untrue statement of a material fact or on the
         Closing Date omits to state a material fact necessary to make the
         statements therein, in the light of the circumstance under which they
         were made, not misleading (except for financial statements and other
         financial data included or incorporated by reference therein as to
         which such counsel need express no opinion); and (x) neither the issue
         or sale of the Securities nor the consummation of any other of the
         transactions contemplated by this Agreement will result in a breach by
         the Company of any terms of, or constitute a default under, the
         Certificate of Incorporation, as amended, or By-Laws of the Company or
         any indenture or other agreement or undertaking of the Company known to
         such counsel.

                  (f) The Representatives shall receive from counsel for the
         Underwriters such opinion or opinions dated the Closing Date with
         respect to the validity of the Securities, the Registration Statement,
         the Prospectus and other related matters as the Representatives may
         reasonably require, and the Company


                                       10
<PAGE>   11
         shall have furnished to such counsel such documents as they reasonably
         request for the purpose of enabling them to pass upon such matters.

                  (g) The Company shall furnish to the Representatives a
         certificate of a Vice President, the Treasurer or the Controller of the
         Company and a Vice President, the Assistant Controller or the Assistant
         Treasurer of the Company, dated the Closing Date, to the effect that
         the signers of such certificate have carefully examined the
         Registration Statement, the Prospectus and this Agreement and that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct on and as of the
                  Closing Date with the same effect as if made on the Closing
                  Date, and the Company has complied with all the agreements and
                  satisfied all the conditions on its part to be performed or
                  satisfied at or prior to the Closing Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued, and no proceedings
                  for that purpose have been instituted, or, to their knowledge,
                  threatened; and

                           (iii) the Registration Statement, as of the later of
                  the date it became effective or the date of filing of the
                  Company's most recent Annual Report on Form 10-K, does not
                  contain any untrue statement of a material fact or omit to
                  state any material fact required to be stated therein or
                  necessary to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading; the
                  Prospectus, including any supplements or amendments thereto
                  and the documents incorporated by reference therein, does not
                  contain any 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, in the light of the
                  circumstances under which they were made, not misleading; and
                  since the effective date of the Registration Statement there
                  has not occurred any event required to be set forth in an
                  amended or supplemented prospectus which has not been so set
                  forth and there has been no document required to be filed
                  under the Exchange Act and the rules and regulations
                  thereunder, which would be deemed to be incorporated by
                  reference in the Prospectus, which has not been so filed.

                  (h) The Representatives (i) shall have received at or prior to
         the time of execution of this Agreement a letter to the Board of
         Directors of the Company dated the date of such delivery and (ii) shall
         receive at the Closing Date, a letter dated the date of delivery
         thereof from the independent accountants of the Company who have
         certified the financial statements of the Company included or


                                       11
<PAGE>   12
         incorporated by reference in the Registration Statement stating that
         (1) with respect to the Company and its subsidiaries they are
         independent accountants within the meaning of the Act and the
         applicable published rules and regulations thereunder; (2) in their
         opinion the unaudited consolidated financial statements of the Company
         and subsidiary companies included or incorporated by reference in the
         Registration Statement and examined by such firm comply as to form in
         all material respects with the applicable accounting requirements of
         the Act and the published rules and regulations thereunder; (3) on the
         basis of the following procedures (but not an examination in accordance
         with generally accepted auditing standards a reading of the minutes of
         meetings of the Board of Directors and stockholders of the Company and
         its subsidiaries since the date of the last audited Balance Sheet as
         set forth in the minute books through a specified date not more than
         five business days prior to the date of delivery of such letter, (B)
         performance of the procedures specified by the American Institute of
         Certified Public Accountants for a review of interim financial
         information as described in SAS 71, Interim Financial Information, on
         the unaudited condensed consolidated interim financial statements of
         the Company and its subsidiaries as incorporated by reference in the
         Registration Statement and the Prospectus, (C) if applicable, a reading
         of the latest available unaudited interim financial data, and (D)
         inquiries of certain officials of the Company who have responsibility
         for financial and accounting matters, nothing has come to their
         attention which caused them to believe that (I) the unaudited condensed
         consolidated interim financial statements, incorporated by reference in
         the Registration Statement and the Prospectus, do not comply as to form
         in all material respects with the applicable accounting requirements of
         the Act and the published rules and regulations thereunder; (II) any
         material modifications should be made to the unaudited condensed
         consolidated interim financial statements, incorporated by reference in
         the Registration Statement and the Prospectus, for them to be in
         conformity with generally accepted accounting principles; and (III) on
         the basis of inquiries of certain officials of the Company who have
         responsibilities for financial and accounting matters and a reading of
         the minutes as stated above, nothing has come to their attention which
         caused them to believe that there was any change at the date of the
         latest available interim financial data and at a specified date not
         more than five business days prior to the date of delivery of such
         letter in the capital stock, other than changes arising as a result of
         sales of Common Stock under the Company's Dividend Reinvestment and
         Stock Purchase Plan and Employee Savings Fund Plan, or long-term debt
         of the Company and its consolidated subsidiaries as compared with
         amounts shown on the latest balance sheet included or incorporated by
         reference in the Registration Statement, or for the period from the
         date of the Company's latest balance sheet included or incorporated by
         reference in the Registration Statement to the end of the preceding
         calendar month for which balance sheet data is available, there were
         any decreases, as compared with the corresponding period in the
         preceding year, in consolidated operating


                                       12
<PAGE>   13
         revenues or net income, or any decreases in unconsolidated
         capitalization, as compared with amounts shown on the latest balance
         sheet included or incorporated by reference in the Registration
         Statement, except in all instances for changes or decreases which the
         Registration Statement discloses have occurred or may occur. The
         letters of such independent accountants also shall be to the effect
         that they have carried out certain specified procedures, not
         constituting an audit, with respect to certain amounts, percentages and
         financial information which are derived from the general accounting
         records of the Company, which appear or are incorporated by reference
         in the Registration Statement and Prospectus and which are specified by
         the Representatives, and have compared such amounts, percentages and
         financial information with the accounting records of the Company and
         have found them to be in agreement.

                  (i) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, there shall
         not have been any change or decrease specified in the letter or letters
         referred to in paragraph (e) of this Section 6 which makes it
         impractical or inadvisable in the judgment of the Representatives to
         proceed with the public offering or the delivery of the Securities as
         contemplated by the Prospectus.

                  (j) Prior to the Closing Date, the Company shall furnish to
         the Representatives such further information, certificates and
         documents as they may reasonably request.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled when and as required by this Agreement, or if any of the
opinions and certificates mentioned above or elsewhere in this Agreement shall
not be in all material respects satisfactory in form and substance to the
Representatives and their counsel, this Agreement and all obligations of the
Underwriters hereunder may be canceled at, or at any time prior to, the Closing
Date by the Representatives. Notice of such cancellation shall be given to the
Company in writing, or by telephone or telegraph confirmed in writing.

                  7. Conditions of Company's Obligations. The obligations of the
Company to sell and deliver the Securities are subject to the following
conditions:

                  (a) Prior to the Closing Date, no stop order suspending the
         effectiveness of the Registration Statement shall have been issued and
         no proceedings for that purpose shall have been instituted or, to the
         knowledge of the Company or the Representatives, threatened.

                  (b) The PSC shall have granted authorization, and on the
         Closing Date such authorization shall be in full force and effect,
         permitting the issuance and


                                       13
<PAGE>   14
         sale of the Securities upon the terms and conditions hereunder set
         forth or contemplated and containing no provision unacceptable to the
         Company.

                  (c) The Underwriters shall have furnished to the Company
         completed underwriters' questionnaires from each underwriter named in
         Schedule II hereto, in form and substance satisfactory to counsel for
         the Company, which disclose no relationship between any such
         underwriter, or its directors, officers or partners, and the Company or
         the Trustee, or the directors, officers or partners thereof, which
         would require, in the opinion of such counsel, an amendment of the
         Statement of Eligibility under the Trust Indenture Act on Form T-l
         filed by the Trustee and disqualification of the Trustee.

                  If any of the conditions specified in this Section 7 shall not
have been fulfilled, this Agreement and all obligations of the Company hereunder
may be canceled on or at any time prior to the Closing Date by the Company.
Notice of such cancellation shall be given to the Underwriters in writing or by
telephone or telegraph confirmed in writing.

                  8. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
or because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof, other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally upon demand for all out-of-pocket expenses (including
fees and disbursements of counsel not to exceed $30,000) that shall have been
reasonably incurred by them in connection with the proposed purchase and sale of
the Securities.

                  9. Indemnification. (a) The Company agrees to indemnify and
hold harmless each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the
Prospectus or in any amendment thereof 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, in
the light of the circumstances under which they were made, not misleading, and
agrees to reimburse each such indemnified party for any legal or other expenses
reasonably incurred by them in connection with investigating


                                       14
<PAGE>   15
or defending any such loss, claim, damage, liability or action; provided,
however, that the Company will 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 any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any Underwriter through
the Representatives specifically for use in connection with the preparation
thereof; and provided, further, that such indemnity with respect to a prospectus
included in the Registration Statement or any amendment thereto prior to the
supplementing thereof with the Prospectus Supplement shall not inure to the
benefit of any Underwriter (or any person controlling such Underwriter) from
whom the person asserting any such loss, claim, damage or liability purchased
the Securities which are the subject thereof if such person did not receive a
copy of the Prospectus as amended or supplemented (but without the documents
incorporated by reference therein) at or prior to the confirmation of the sale
of such Securities to such person in any case where such delivery is required by
the Act and the untrue statement or omission of a material fact contained in the
Prospectus was corrected in the Prospectus as amended or supplemented. This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

                  (b) Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who has signed
the Registration Statement and each person, if any, who controls the Company
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from the Company to the Underwriters but only with
reference to written information furnished to the Company by or on behalf of
such Underwriter through the Representatives specifically for use in the
preparation of the documents referred to in the foregoing indemnity, and agrees
to reimburse each such indemnified party for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action. This indemnity agreement will be
in addition to any liability which any Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 9, notify the indemnifying party in writing of the
commencement thereof; but the omission to so notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 9. In case any such action is brought against
any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein, and, to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel satisfactory to
such indemnified party; provided, however,


                                       15
<PAGE>   16
if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party, or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under this Section 9 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection with the assertion of legal defenses in accordance with the proviso
to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by the Representatives in the case of subparagraph
(a), representing the indemnified parties under subparagraphs (a) or (b), as the
case may be, who are parties to such action), (ii) the indemnifying party shall
not have employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action or (iii) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party; and except
that, if clause (i) or (iii) is applicable, such liability shall be only in
respect of the counsel referred to in such clause (i) or (iii). In any case to
which an exception set forth in (i), (ii) or (iii) above applies, the fees and
expenses of counsel shall be at the expense of the indemnifying party.

                  (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in subparagraph (a) is
due in accordance with its terms but is for any reason unavailable from the
Company or insufficient to hold the Underwriters harmless in respect of any
losses claims, damages or liabilities (or actions in respect thereof) referred
to therein, the Company and the Underwriters shall contribute to the aggregate
losses, claims, damages and liabilities (or actions in respect thereof) to which
the Company and one or more of the Underwriters may be subject, 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 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 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 the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or


                                       16
<PAGE>   17
omission. The relative benefits received by the Company on the one hand and the
Underwriters on the other shall be deemed to be in the same proportion as the
total net proceeds from the offering of the Securities (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters with respect to the offering of the
Securities, in each case as set forth in the table on the cover page of the
Prospectus Supplement. Notwithstanding the foregoing, no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Company and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this subparagraph
(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 subparagraph (d). The amount paid or payable by a party entitled to
contribution as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subparagraph (d) shall be
deemed to include any legal or other expenses reasonably incurred by such party
in connection with investigating or defending any such action or claim. The
Underwriters' obligations under this subparagraph (d) are several in proportion
to their respective underwriting obligations and not joint. For purposes of this
subparagraph (d), each person, if any, who controls an Underwriter within the
meaning of either the Act or the Exchange Act shall have the same rights to
contribution as such Underwriter, and each person, if any, who controls the
Company within the meaning of either the Act or the Exchange Act, each officer
of the Company who shall have signed the Registration Statement and each
director of the Company shall have the same rights to contribution as the
Company, subject to the fourth sentence of this subparagraph (d).

                  10. Default by an Underwriter. If any one or more of the
Underwriters shall fail to purchase and pay for all of the Securities agreed to
be purchased by such Underwriter or Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the amount
of Securities set forth opposite their names in Schedule II hereto bears to the
aggregate amount of Securities set forth opposite the names of all the remaining

      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 his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as

other action provided or permitted by this Indenture to be given, made or taken

substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

      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. 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. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

      The ownership of Securities shall be proved by the Security Register.

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
Security.

      The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

      The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which


                                      -19-
<PAGE>   20
a record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the Company's expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Company in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

      Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.


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

      Any request, demand, authorization, direction, notice, consent, 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,

         (1) the Trustee by any Holder or by the Company shall be sufficient for
   every purpose hereunder if made, given, furnished or filed in writing to or
   with the Trustee at its Corporate Trust Office, Attention: .................,
   or

         (2) 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 mailed,


                                      -20-
<PAGE>   21
   first-class postage prepaid, to the Company addressed to it at the address of
   its principal office specified in the first paragraph of this instrument or
   at any other address previously furnished in writing to the Trustee by the
   Company.


SECTION 106. Notice to Holders; Waiver.

      Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. 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. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, 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.

      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 by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.


SECTION 107. Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.


SECTION 108. Effect of Headings and Table of Contents.

      The Article and Section headings herein 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 in the Securities 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 in the Securities, express or implied, shall
give to any Person, other than the parties hereto and 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 Securities shall be governed by and construed in
accordance with the law of the State of New York.


SECTION 113. Legal Holidays.

      In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security 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.

<PAGE>   33
   Depositaries for such Global Securities, the form of any legend or legends
   which shall be borne by any such Global Security in addition to or in lieu of
   that set forth in Section 204 and any circumstances in addition to or in lieu
   of those set forth in Clause (2) of the last paragraph of Section 305 in
   which any such Global Security may be exchanged in whole or in part for
   Securities registered, and any transfer of such Global Security in whole or
   in part may be registered, in the name or names of Persons other than the
   Depositary for such Global Security or a nominee thereof;

      (17) any provision necessary to permit or facilitate the issuance, payment
   or conversion of any Securities of the series that may be converted into

      (18) any addition to or change in the Events of Default which applies to

   901(5)).

      All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 303) set forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

      If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.


SECTION 302. Denominations.

      The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series,


                                      -33-
<PAGE>   34
the Securities of such series shall be issuable in denominations of $1,000 and
any integral multiple thereof.


SECTION 303. Execution, Authentication, Delivery and Dating.

      The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its Vice Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

      Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper 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 Securities or did not
hold such offices at the date of such Securities.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

       (1) if the form of such Securities has been established by or pursuant to
   Board Resolution as permitted by Section 201, that such form has been
   established in conformity with the provisions of this Indenture;

       (2) if the terms of such Securities have been established by or pursuant
   to Board Resolution as permitted by Section 301, that such terms have been
   established in conformity with the provisions of this Indenture; and

       (3) that such Securities, when authenticated and delivered by the Trustee
   and issued by the Company in the manner and subject to any conditions
   specified in such Opinion of Counsel, will constitute valid and legally
   binding obligations of the Company enforceable in accordance with their
   terms, subject to bankruptcy, insolvency, fraudulent transfer,
   reorganization, moratorium and similar laws of general applicability relating
   to or affecting creditors' rights and to general equity principles.


                                      -34-
<PAGE>   35
If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.


SECTION 304. Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for


                                      -35-
<PAGE>   36
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.


SECTION 305. Registration, Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

      Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of like tenor and aggregate
principal amount.

      At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

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

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



                                      -36-
<PAGE>   37
      No service charge shall be made for any registration of transfer or
exchange of Securities, 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 Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

      If the Securities of any series (or of any series and specified tenor) are
to be redeemed in part, the Company shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption under Section 1103 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of
or exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

       (1) Each Global Security authenticated under this Indenture shall be
   registered in the name of the Depositary designated for such Global Security
   or a nominee thereof and delivered to such Depositary or a nominee thereof or
   custodian therefor, and each such Global Security shall constitute a single
   Security for all purposes of this Indenture.

       (2) Notwithstanding any other provision in this Indenture, no Global
   Security may be exchanged in whole or in part for Securities registered, and
   no transfer of a Global Security in whole or in part may be registered, in
   the name of any Person other than the Depositary for such Global Security or
   a nominee thereof unless (A) such Depositary (i) has notified the Company
   that it is unwilling or unable to continue as Depositary for such Global
   Security or (ii) has ceased to be a clearing agency registered under the
   Exchange Act, (B) there shall have occurred and be continuing an Event of
   Default with respect to such Global Security or (C) there shall exist such
   circumstances, if any, in addition to or in lieu of the foregoing as have
   been specified for this purpose as contemplated by Section 301.

       (3) Subject to Clause (2) above, any exchange of a Global Security for
   other Securities may be made in whole or in part, and all Securities issued
   in exchange for a Global Security or any portion thereof shall be registered
   in such names as the Depositary for such Global Security shall direct.

       (4) Every Security authenticated and delivered upon registration of
   transfer of, or in exchange for or in lieu of, a Global Security or any
   portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
   1107 or otherwise, shall be authenticated and


                                      -37-
<PAGE>   38
   delivered in the form of, and shall be, a Global Security, unless such
   Security is registered in the name of a Person other than the Depositary for
   such Global Security or a nominee thereof.


SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

      If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security 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 (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be 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 Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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

      Upon the issuance of any new Security 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 expenses (including
the fees and expenses of the Trustee) connected therewith.

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




                                      -38-
<PAGE>   39
SECTION 307. Payment of Interest; Interest Rights Preserved.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Security 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 Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

      Any interest on any Security 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 relevant 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 (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
      the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on 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 Security 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 cause notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor to be given to each Holder of Securities of such series in the
      manner set forth in Section 106, 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
      Securities of such series (or their respective Predecessor Securities) are
      registered at the close of business on such Special Record Date and shall
      no longer be payable pursuant to the following Clause (2).

         (2) The Company may make payment of any Defaulted Interest on the
      Securities of any series in any other lawful manner not inconsistent with
      the requirements of any


                                      -39-
<PAGE>   40
      securities exchange on which such Securities 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, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

      In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security (or one or more Predecessor Security) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediate preceding sentence, in the case of
any Security which is converted, interest whose Stated Maturity is after the
date of conversion of such Security shall not be payable. Notwithstanding the
foregoing, the terms of any Security that may be converted may provide that the
provisions of this paragraph do not apply, or apply with such additions, changes
or omissions as may be provided thereby, to such Security.


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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of and any premium and
(subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.


SECTION 309. Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in


                                      -40-
<PAGE>   41
any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order.


SECTION 310. Computation of Interest.

      Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                           SATISFACTION AND DISCHARGE


SECTION 401. Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

      (1) either

         (A) all Securities theretofore authenticated and delivered (other than
      (i) Securities which have been destroyed, lost or stolen and which have
      been replaced or paid as provided in Section 306 and (ii) Securities for
      whose payment money has theretofore been deposited in trust or segregated
      and held in trust by the Company and thereafter repaid to the Company or
      discharged from such trust, as provided in Section 1003) have been
      delivered to the Trustee for cancellation; or

         (B) all such Securities not theretofore delivered to the Trustee for
      cancellation

             (i) have become due and payable, or

            (ii) will become due and payable at their Stated Maturity within one
         year, or

         arrangements satisfactory to the Trustee for the giving of notice of
         redemption by the Trustee in the name, and at the expense, of the
         Company,

      and the Company, in the case of (i), (ii) or (iii) above, has deposited or
      caused to be deposited with the Trustee as trust funds in trust for the
      purpose money in an amount sufficient to pay and discharge the entire
      indebtedness on such Securities not theretofore delivered to the Trustee
      for cancellation, for principal and any premium and interest to the date
      of such deposit (in the case of Securities which have become due and
      payable) or to the Stated Maturity or Redemption Date, as the case may be;

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

      (3) the Company has delivered to the Trustee an Officers' Certificate and
   an Opinion of Counsel, each stating that all conditions precedent herein
   provided for relating to the satisfaction and discharge of this Indenture

obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.


SECTION 402. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

SECTION 501.  Events of Default.

     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

     (1) default in the payment of any interest upon any Security of that series
   when it becomes due and payable, and continuance of such default for a period

     (2) default in the payment of the principal of or any premium on any
   Security of that series at its Maturity; or

     (3) default in the deposit of any sinking fund payment, when and as due by

     (4) default in the performance, or breach, of any covenant or warranty of
   the Company in this Indenture (other than a covenant or warranty a default in
   whose performance or whose breach is elsewhere in this Section specifically
   dealt with or which has expressly been included in this Indenture solely for
   the benefit of series of Securities other than that series), and continuance
   of such default or breach 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 10% in principal amount of
   the Outstanding Securities of that 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; or

     (5) the entry by a court having jurisdiction in the premises of (A) 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 (B) a decree or order adjudging the
   Company a bankrupt or insolvent, or approving as properly filed a petition
   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 of the Company or of any substantial part of its
   property, or ordering the winding up or liquidation of its affairs, and the
   continuance of any such decree or order


                                     -43-
<PAGE>   44
   for relief or any such other decree or order unstayed and in effect for a
   period of 60 consecutive days; or

     (6) 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 an involuntary 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 other 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 taking of
   corporate action by the Company in furtherance of any such action; or

     (7) any other Event of Default provided with respect to Securities of that
series.


SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(5)
or 501 (6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a


                                      -44-
<PAGE>   45
majority in principal amount of the Outstanding Securities of that series, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

      (1) the Company has paid or deposited with the Trustee a sum sufficient to
   pay

        (A) all overdue interest on all Securities of that series,

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

        (C) to the extent that payment of such interest is lawful, interest upon
     overdue interest at the rate or rates prescribed therefor in such
     Securities, and

        (D) all sums paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel;

   and

     (2) all Events of Default with respect to Securities of that series, other
   than the non-payment of the principal of Securities of that series which have
   become due solely by such declaration of acceleration, have been cured or
   waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.


SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

     (1) default is made in the payment of any interest on any Security when
   such interest becomes due and payable and such default continues for a period
   of 30 days, or

     (2) default is made in the payment of the principal of (or premium, if any,
   on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be


                                      -45-
<PAGE>   46
legally enforceable, interest on any overdue principal and premium and on any
overdue interest, at the rate or rates prescribed therefor in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities 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 504.  Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized 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 amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

     No provision of this Indenture 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 Securities
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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities 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 of the Securities in respect of which such judgment has been
recovered.


SECTION 506.  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 any premium
or interest, upon presentation of the Securities 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 607; and

     SECOND: To the payment of the amounts then due and unpaid for principal of
   and any premium and interest on the Securities 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
   Securities for principal and any premium and interest, respectively.


SECTION 507.  Limitation on Suits.

     No Holder of any Security of any series 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

     (1) such Holder has previously given written notice to the Trustee of a
   continuing Event of Default with respect to the Securities of that series;

     (2) the Holders of not less than 25% in principal amount of the Outstanding
   Securities of that series shall have made written request to the Trustee to
   institute proceedings in respect of such Event of Default in its own name as
   Trustee hereunder;



                                      -47-
<PAGE>   48
     (3) such Holder or Holders have offered to the Trustee reasonable indemnity
   against the costs, expenses and liabilities to be incurred in compliance with
   such request;

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

     (5) no direction inconsistent with such written request has been given to
   the Trustee during such 60-day period by the Holders of a majority in
   principal amount of the Outstanding Securities of that series;

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

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (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 509.  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 has been discontinued
or abandoned for any reason, or has 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, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

<PAGE>   49
SECTION 510.  Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities 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 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 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities 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 512.  Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities
of any 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 Securities of
such series, provided that

     (1) such direction shall not be in conflict with any rule of law or with
   this Indenture, and

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


SECTION 513.  Waiver of Past Defaults.

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


                                      -49-
<PAGE>   50
     (1) in the payment of the principal of or any premium or interest on any
     Security of such series, or

     (2) in respect of a covenant or provision hereof which under Article Nine
     cannot be modified or amended without the consent of the Holder of each
     Outstanding Security of such series affected.

     Upon any such waiver, such default shall cease to exist, and any Event 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 514.  Undertaking for Costs.

     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, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.


SECTION 515.  Waiver of Usury, 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 usury, 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 601.  Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, 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. 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 602.  Notice of Defaults.

     If a default occurs hereunder with respect to Securities of any series, the
Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.


SECTION 603.  Certain Rights of Trustee.

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining
   from acting upon any resolution, certificate, statement, instrument, opinion,
   report, notice, request, direction, consent, order, bond, debenture, note,
   other evidence of indebtedness or other paper or document believed by it to
   be genuine and to have been signed or presented by the proper party or
   parties;

   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 Officers' Certificate;

     (4) the Trustee may consult with counsel and the written advice of such
   counsel or any Opinion of Counsel shall be full and complete authorization
   and protection in respect of any action taken, suffered or omitted by it
   hereunder in good faith and in reliance thereon;

     (5) the Trustee shall be under no obligation to exercise any of the rights
   or powers vested in it by this Indenture at the request or direction of any
   of the Holders pursuant to this Indenture, unless such Holders shall have
   offered to the Trustee reasonable security or indemnity against the costs,
   expenses and liabilities which might be incurred by it in compliance with
   such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts
   or matters stated in any resolution, certificate, statement, instrument,
   opinion, report, notice, request, direction, consent, order, bond, debenture,
   note, other evidence of indebtedness or other paper or 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 be entitled
   to examine the books, records and premises of the Company, personally or by
   agent or attorney; and

     (7) the Trustee may execute any of the trusts or powers hereunder or
   perform any duties hereunder either directly or by or through agents or
   attorneys and the Trustee shall not be responsible for any misconduct or
   negligence on the part of any agent or attorney appointed with due care by it
   hereunder.


SECTION 604.  Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, 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 any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the


                                     -52-

Securities. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of Securities or the
proceeds thereof.


SECTION 605.  May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.


SECTION 606.  Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.


SECTION 607.  Compensation and Reimbursement.

     The Company agrees

     (1) to 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);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee
   upon its request for all reasonable expenses, disbursements and advances
   incurred or made by the Trustee in accordance with any provision of this
   Indenture (including the reasonable compensation and the expenses and
   disbursements of its agents and counsel), except any such expense,
   disbursement or advance as may be attributable to its negligence or bad
   faith; and

     (3) to indemnify the Trustee for, and to hold it harmless against, any
   loss, liability or expense 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, 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.

SECTION 608.  Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series [or a trustee under -- list here any prior
indentures between the Company and the Trustee that have not been satisfied and
discharged and that may be excluded by the proviso to Section 310(b)(1) of the
Trust Indenture Act].


SECTION 609.  Corporate Trustee Required; Eligibility.

     There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person 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 with respect to the Securities of any series 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 610.  Resignation and Removal; Appointment of Successor.

     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 611.

     The Trustee may resign at any time with respect to the Securities 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 611 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
Securities of such series.



                                     -54-
<PAGE>   55
     The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

     If at any time:

     (1) the Trustee shall fail to comply with Section 608 after written request
   therefor by the Company or by any Holder who has been a bona fide Holder of a
   Security for at least six months, or

     (2) the Trustee shall cease to be eligible under Section 609 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,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security 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
Securities and the appointment of a successor Trustee or Trustees.

     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, with respect to
the Securities of one or more series, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may
be appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities 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 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, any
Holder who


                                     -55-
<PAGE>   56
has been a bona fide Holder of a Security of such series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

     The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee with respect to
all Securities, 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; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, 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.

     In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities 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, trusts and duties of the
retiring Trustee with respect to the Securities 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 Securities, 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 Securities 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


                                     -56-
<PAGE>   57
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 Securities 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 shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

     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 612.  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 Securities 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 Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.


SECTION 613.  Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust


                                     -57-
<PAGE>   58
Indenture Act regarding the collection of claims against the Company (or any
such other obligor).


SECTION 614.  Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 306, and Securities 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 Securities 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 of America, any State thereof
or the District of Columbia, 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 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,


                                     -58-
<PAGE>   59
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 and
shall give notice of such appointment in the manner provided in Section 106 to
all Holders of Securities of the series with respect to which such
Authenticating Agent will serve. 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.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

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

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of


                                     -66-
<PAGE>   67
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency.


SECTION 1003.  Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay such amount, such sum to be held as provided by the Trust
Indenture Act, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than 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 will (1) comply with the provisions of the
Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, 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, 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 or any premium or
interest on any


                                     -67-
<PAGE>   68
Security of any series and remaining unclaimed for two years after such
principal, premium 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 the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, 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 repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, notice 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 publication, any unclaimed balance of such money then remaining
will be repaid to the Company.


SECTION 1004.  Statement by Officers as to Default.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

     One of the officers signing an Officers' Certificate given pursuant to this
Section shall be the principal executive, financial or accounting officer of the
Company.


SECTION 1005.  Existence.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1006.  Maintenance of Properties.

     The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will 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 and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.


SECTION 1007.  Payment of Taxes and Other Claims.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (1) all taxes, assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.


SECTION 1008.  Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series, the Company may, with respect to the Securities of any series,
omit in any particular instance to comply with any term, provision or condition
set forth in any covenant provided pursuant to Section 301(18), 901(2) or 901(7)
for the benefit of the Holders of such series or in either of Sections 1006 or
1007, if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities of such series shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but 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.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES


SECTION 1101.  Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for such Securities) in accordance with
this Article.


SECTION 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section 301
for such Securities. In case of any redemption at the election of the Company of
less than all the Securities of any series (including any such redemption
affecting only a single Security), the Company shall, at least 60 days prior to
the Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.


SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from


                                     -70-
<PAGE>   71
the Outstanding Securities of such series and specified tenor not previously
called for redemption in accordance with the preceding sentence.

     If any Security selected for partial redemption is converted in part before
termination of the conversion right with respect to the portion of the Security
so selected, the converted portion of such Security shall be deemed (so far as
may be) to be the portion selected for redemption. Securities which have been
converted during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purposes of such selection.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for
partial redemption as aforesaid, the principal amount thereof to be redeemed.

     The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security, whether such Security is to
be redeemed in whole or in part. In the case of any such redemption in part, the
unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.


SECTION 1104.  Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

     (1)  the Redemption Date,

     (2)  the Redemption Price,

     (3) if less than all the Outstanding Securities of any series consisting of
   more than a single Security are to be redeemed, the identification (and, in
   the case of partial redemption of any such Securities, the principal amounts)
   of the particular Securities to be redeemed and, if less than all the
   Outstanding Securities of any series consisting of


                                     -71-
<PAGE>   72
   a single Security are to be redeemed, the principal amount of the particular
   Security to be redeemed,

     (4) that on the Redemption Date the Redemption Price will become due and
   payable upon each such Security to be redeemed and, if applicable, that
   interest thereon will cease to accrue on and after said date,

     (5) the place or places where each such Security is to be surrendered for
   payment of the Redemption Price, and

     (6) that the redemption is for a sinking fund, if such is the case.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.


SECTION 1105.  Deposit of Redemption Price.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

     If any Security called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any Predecessor Security to receive interest as provided in the
last paragraph of Section 307 or in the terms of such Security) be paid to the
Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.

SECTION 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, instalments of interest whose Stated Maturity is on
or prior


                                     -72-
<PAGE>   73
to the Redemption Date will be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of Section
307.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.


SECTION 1107.  Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.


                                 ARTICLE TWELVE

                                  SINKING FUNDS


SECTION 1201.  Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment", and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment". If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

<PAGE>   74
SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to any Securities of such series required to be made pursuant to the terms of
such Securities as and to the extent provided for by the terms of such
Securities; provided that the Securities to be so credited have not been
previously so credited. The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified
in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.


SECTION 1203.  Redemption of Securities for Sinking Fund.

     Not less than 40 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 35 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 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 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301.  Company's Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or


                                     -74-
<PAGE>   75
1303, in accordance with any applicable requirements provided pursuant to
Section 301 and upon compliance with the conditions set forth below in this
Article. Any such election shall be evidenced by a Board Resolution or in
another manner specified as contemplated by Section 301 for such Securities.


SECTION 1302.  Defeasance and Discharge.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (4) this Article. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have
Section 1303 applied to such Securities.


SECTION 1303.  Covenant Defeasance.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Section 801(3),
Sections 1006 [and 1007], and any covenants provided pursuant to Section
301(18), 901(2) or 901(7) for the benefit of the Holders of such Securities and
(2) the occurrence of any event specified in Sections 501(4) (with respect to
any of Section 801(3), Sections 1006 [and 1007], and any such covenants provided
pursuant to Section 301(18), 901(2) or 901(7)), and 501(7) shall be deemed not
to be or result in an Event of Default, in each case with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in


                                     -75-
<PAGE>   76
any such specified Section (to the extent so specified in the case of Section
501(4)), whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any such Section to
any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.


SECTION 1304.  Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be:

     (1) The Company shall irrevocably have deposited or caused to be deposited
   with the Trustee (or another trustee which satisfies the requirements
   contemplated by Section 609 and agrees to comply with the provisions of this
   Article applicable to it) as trust funds in trust for the purpose of making
   the following payments, specifically pledged as security for, and dedicated
   solely to, the benefits of the Holders of such Securities, (A) money in an
   amount, or (B) U.S. Government Obligations which through the scheduled
   payment of principal and interest in respect thereof in accordance with their
   terms will provide, not later than one day before the due date of any
   payment, money in an amount, or (C) a combination thereof, in each case
   sufficient, in the opinion of a nationally recognized firm of independent
   public accountants expressed in a written certification thereof delivered to
   the Trustee, to pay and discharge, and which shall be applied by the Trustee
   (or any such other qualifying trustee) to pay and discharge, the principal of
   and any premium and interest on such Securities on the respective Stated
   Maturities, in accordance with the terms of this Indenture and such
   Securities. As used herein, "U.S. Government Obligation" means (x) any
   security which is (i) a direct obligation of the United States of America for
   the payment of which the full faith and credit of the United States of
   America is pledged or (ii) an obligation of a Person controlled or supervised
   by and acting as an agency or instrumentality of the United States of America
   the payment of which is unconditionally guaranteed as a full faith and credit
   obligation by the United States of America, which, in either case (i) or
   (ii), is not callable or redeemable at the option of the issuer thereof, and
   (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of
   the Securities Act) as custodian with respect to any U.S. Government
   Obligation which is specified in Clause (x) above and held by such bank for
   the account of the holder of such depositary receipt, or with respect to any
   specific payment of principal of or interest on any U.S. Government
   Obligation which is so specified and held, provided that (except as required
   by law) such custodian is not authorized to make any deduction from the
   amount payable to the holder of such depositary receipt from any amount
   received by the custodian in respect of the U.S. Government Obligation or the
   specific payment of principal or interest evidenced by such depositary
   receipt.


                                     -76-
<PAGE>   77
     (2) In the event of an election to have Section 1302 apply to any
   Securities or any series of Securities, as the case may be, the Company shall
   have delivered to the Trustee an Opinion of Counsel stating that (A) the
   Company has received from, or there has been published by, the Internal
   Revenue Service a ruling or (B) since the date of this instrument, there has
   been a change in the applicable Federal income tax law, in either case (A) or
   (B) to the effect that, and based thereon such opinion shall confirm that,
   the Holders of such Securities will not recognize gain or loss for Federal
   income tax purposes as a result of the deposit, Defeasance and discharge to
   be effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit, Defeasance and discharge were not to
   occur.

     (3) In the event of an election to have Section 1303 apply to any
   Securities or any series of Securities, as the case may be, the Company shall
   have delivered to the Trustee an Opinion of Counsel to the effect that the
   Holders of such Securities will not recognize gain or loss for Federal income
   tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

     (4) The Company shall have delivered to the Trustee an Officer's
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.

     (5) No event which is, or after notice or lapse of time or both would
   become, an Event of Default with respect to such Securities or any other
   Securities shall have occurred and be continuing at the time of such deposit
   or, with regard to any such event specified in Sections 501(5) and (6), at
   any time on or prior to the 90th day after the date of such deposit (it being
   understood that this condition shall not be deemed satisfied until after such
   90th day).

     (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to
   have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

     (7) Such Defeasance or Covenant Defeasance shall not result in a breach or
   violation of, or constitute a default under, any other agreement or
   instrument to which the Company is a party or by which it is bound.

     (8) Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment


                                     -77-
<PAGE>   78
   Company Act unless such trust shall be registered under such Act or exempt
   from registration thereunder.

     (9) The Company shall have delivered to the Trustee an Officer's
   Certificate and an Opinion of Counsel, each stating that all conditions
   precedent with respect to such Defeasance or Covenant Defeasance have been
   complied with.


SECTION 1305.  Deposited Money and U.S. Government Obligations to Be
   Held in Trust; Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.


SECTION 1306.  Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court


                                     -78-

or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations under this Indenture and such Securities from
which the Company has been discharged or released pursuant to Section 1302 or
1303 shall be revived and reinstated as though no deposit had occurred pursuant
to this Article with respect to such Securities, until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust pursuant to
Section 1305 with respect to such Securities in accordance with this Article;
provided, however, that if the Company makes any payment of principal of or any
premium or interest on any such Security following such reinstatement of its
obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities to receive such payment from the money so held in
trust.

                              _____________ SERIES]


         This Bond is one of a duly authorized issue of Bonds of the Company, of
an unlimited (except as provided in the Indenture hereinafter mentioned)
permitted principal amount, all issued or to be issued in one or more series
(the Bonds of the series of which this Bond is a part being herein called the
"Bonds of the _________ Series"), all of the Bonds of all series being issued or
to be issued under and, irrespective of the time of issue, all equally secured
by a Mortgage Trust Indenture (herein, with all instruments stated to be
supplemental thereto to which the Trustee hereinafter named is

                                      -2-

or shall be a party, called the "Indenture"), dated as of October 1, 1937, to
Marine Midland Bank, N.A. (successor to Marine Midland Bank which was formerly
named The Marine Midland Trust Company of New York and thereafter Marine Midland
Grace Trust Company of New York and Marine Midland Bank - New York and
hereinafter, with its successors as defined in the Indenture, referred to as the
"Trustee"), to which Indenture, an executed counterpart of which is on file with
the Trustee, reference is hereby made for a description of the property
mortgaged and pledged to the Trustee, and for a statement of the nature and
extent of the security, the rights of the holders of the Bonds with respect to
such security, and the terms and conditions upon which said Bonds are or are to
be issued and secured; but neither the foregoing reference to the Indenture, nor
any provision of this Bond or of the Indenture, shall affect or impair the
obligation of the Company, which is absolute and unconditional, to pay, at the
stated or accelerated maturities herein provided, the principal of and interest
on this Bond as herein provided.

         The Indenture and the rights and obligations of the Company and of the
holders of the Bonds thereunder may be changed or modified at any time upon the
consent and approval of the Company and of the holders of 66 2/3 per cent in
principal amount of the Bonds then outstanding affected by such change or
modification, given as provided in the Indenture, and in the manner and subject
to the limitations therein set forth; provided, that no such change or
modification shall (a) alter or impair the obligation of the Company to pay the
principal of and interest on any Bond at the time and place and at the rate and
in the currency provided therein, without the consent of the holder of such
Bond, (b) permit the creation by the Company of any mortgage, or lien in the
nature of a mortgage, ranking prior to or pari passu with the lien of the
Indenture, or alter adversely to the Bondholders the character of the lien of
the Indenture, except as in the Indenture otherwise expressly provided, unless
the creation of such mortgage or lien, or such alteration of the lien of the
Indenture, be consented to by the holders of all outstanding Bonds, (c) affect
the Trustee unless consented to by the Trustee or (d) permit a reduction of the
percentage required for any change or modification of the Indenture, without the
consent of the holders of all outstanding Bonds.

         The principal of this Bond together with accrued interest thereon may
be declared, or may become, due and

                                      -3-

payable before maturity in certain events, on the conditions, in the manner and
with the effect set forth in the Indenture.

         Subsequent to the initial authentication of the Bonds of the
____________ Series, each Bond of the _________ Series shall be dated as of the
date of its authentication, and 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 provided for (unless the date of such Bond is a ________ 1 or a
________ 1 to which interest has been paid or provided for, in which case such
Bond shall bear interest from its date, or unless the date of such Bond is prior
to the payment of any interest on the Bonds of the ____________ Series, in which
case such Bond shall bear interest from ____ 1, 20__). However, so long as there
is no existing default in the payment of interest on the Bonds of the __________
Series, any such Bond authenticated by the Trustee after the close of business
on the record date for any interest payment date and prior to such interest
payment date shall be dated the date of its authentication, but shall bear
interest from such interest payment date; provided, however, that if and to the
extent that the Company shall default in the payment of interest on such
interest payment date, then 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 previously been paid or made available for payment on the
outstanding Bonds of the __________ Series or, if no interest has been paid on
such Bonds, from the date of initial authentication of Bonds of the ___________
Series.

         The Bonds of the __________ Series are entitled to the benefit of a
maintenance fund referred to in Part II of the Supplemental Indenture creating
the Bonds of the __________ Series. Except as hereinafter provided, the Bonds of
the ____________ Series may be redeemed at the option of the Company, either as
a whole or in part, on any date, whether or not an interest payment date, at the
following general redemption prices (expressed in percentages of principal
amount) and are subject to the redemption as a whole or in part by operation of
said maintenance fund at the following special redemption prices (expressed in

of any refunding operation, by the application, directly or indirectly, of
borrowed funds having an effective interest cost to the Company or any
subsidiary of the Company (calculated in accordance with accepted financial
practice) of less than ____% per annum.

         No recourse shall be had for the payment of any part of principal of,

redemption hereof prior to maturity), or for any claim based hereon or thereon,

expressly waived and released by the acceptance of this Bond and as part of the
consideration for the issue hereof, as provided in the Indenture.

         If this Bond or any part thereof is called for redemption and payment
duly provided, this Bond or such part thereof shall cease to bear interest from
and after the date for such redemption.

         Registration of transfer of this Bond may be made by the registered
owner in person or by duly authorized attorney, at the corporate trust office of
the Trustee, or at such other offices or agencies of the Trustee or the Company
as shall be maintained for such purpose, upon the surrender of this Bond, and
thereupon a new Bond or Bonds of authorized denominations of the same series for
a like aggregate principal amount will be issued to the registered transferee,
all in the manner and subject to the terms, conditions and limitations specified
in the Indenture. No service charge shall be made for any exchange or
registration of transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto. The Company and the Trustee may deem and treat the person in
whose name this Bond is registered as the absolute owner hereof for the purpose
of receiving payment of or on account of the principal and interest due hereon
(subject to the provisions of the first paragraph of this Bond) and for all
other purposes, and neither the Company, the Trustee nor any paying agent or
agency shall be affected by any notice to the contrary, whether this Bond or
such interest shall be overdue or not.

Ladies and Gentlemen:

         In connection with the registration under the Securities Act of 1933
(the "Act") of $500,000 of: (i) your First Mortgage Bonds (the "Bonds"), to be

between Niagara Mohawk Power Corporation (the "Company") and Marine Midland

"Debentures" and together with the Bonds, the "Securities") to be issued from
time to time pursuant to an Indenture (the "Debentures Indenture") between the
Company and Bank of New York (the "Debentures Trustee"), we, as your counsel,
have examined such corporate records, certificates and other documents, and such
questions of law, as we have considered necessary or appropriate for the
purposes of this opinion.

NIAGARA MOHAWK POWER CORPORATION

         Upon the basis of such examination, we advise you that, in our opinion:

                  (i) when the Registration Statement has become effective under
         the Act, the Debentures Indenture has been duly authorized, executed
         and delivered, the terms of the Debentures and of their issuance and
         sale have been duly established so as not to violate any applicable law
         or result in a default under or breach of any agreement or instrument
         binding upon the Company and so as to comply with any requirement or
         restriction imposed by any court or governmental body having
         jurisdiction over the Company, and the Debentures have been duly
         executed and authenticated in accordance with the Debentures Indenture
         and issued and sold as contemplated in the Registration Statement, the
         Debentures will constitute valid and legally binding obligations of the
         Company, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles; and
<PAGE>   2
                  (ii) when the Registration Statement has become effective
         under the Act, the terms of the Bonds and of their issuance and sale
         have been duly established so as not to violate any applicable law or
         result in a default under or breach of any agreement or instrument
         binding upon the Company and so as to comply with any requirement or
         restriction imposed by any court or governmental body having
         jurisdiction over the Company, and the Bonds have been duly executed
         and authenticated in accordance with the Mortgage and issued and sold
         as contemplated in the Registration Statement, the Bonds will
         constitute valid and legally binding obligations of the Company,
         subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and similar laws of general applicability relating to or
         affecting creditors' rights and to general equity principles.

                  In rendering the foregoing opinion, we are expressing no
opinion as to Federal or state laws relating to fraudulent transfers.

                  The foregoing opinion is limited to the Federal laws of the
United States and the laws of the state of New York and we are expressing no
opinion as to the effect of the laws of any other jurisdiction.

                  We have relied as to certain matters on information obtained
from public officials, officers of the Company and other sources believed by us
to be responsible.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the references to us under the heading
"Validity of Debt Securities" in the Prospectus. In giving such consent, we do
not thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Act.

                                      Very truly yours,
