                                  THE COMPANY
 
  Puget Sound Energy, Inc., formerly Puget Sound Power & Light Company (the
"Company"), is an investor-owned public utility incorporated in the state of
Washington furnishing electric and, since February 10, 1997, gas service in a
territory covering approximately 6,000 square miles, principally in the Puget
Sound region of Washington state. On February 10, 1997, the Company completed
a merger (the "Merger") with the Washington Energy Company ("WECo") and its
principal subsidiary, Washington Natural Gas Company ("WNG"). Seattle-based
WNG provided natural gas distribution service in an area east of Puget Sound
that includes Seattle, Tacoma, Everett, Bellevue and Olympia. The Company
changed its name to Puget Sound Energy, Inc. effective with the Merger. The
Company's executive office is located at 411-108th Avenue N.E., Bellevue,
Washington 98004-5515, and its telephone number is (425) 454-6363.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
  The following table sets forth the Company's ratios of earnings to fixed
charges for the respective periods indicated:

</TABLE>
- --------
(1) The ratio for the twelve months ended September 30, 1997 includes charges
    incurred in connection with the Merger. Had such charges been excluded
    from earnings, the ratio of earnings to fixed charges for such period
    would have been 3.1x.
 
(2) As a result of the Merger, each of the Company's ratios reflects the
    combined operations of the Company and WECo. Because WECo's fiscal year
    ended September 30, the combined ratios for the five years ended December
    31, 1996 reflect the fiscal years ended December 31 for the Company and
    September 30 for WECo. September 30 ratios are comprised of the results of
    the Company and WECo for the twelve months ended September 30.
 
(3) For purposes of computing the ratios of earnings to fixed charges,
    earnings represent income from continuing operations before extraordinary
    items and cumulative effect of changes in accounting principles plus
    applicable income taxes and fixed charges. Fixed charges include all
    interest expense and the proportion deemed representative of the interest
    factor of rent expense.

                                USE OF PROCEEDS
 
  Except as otherwise set forth in any Prospectus Supplement, the net proceeds
to be received by the Company from the issuance and sale of the Senior Notes
will initially become part of the general funds of the Company and will be
used for the repayment of all or a portion of the Company's outstanding short-
term borrowings incurred for the Company's construction program or for the
payment at maturity or upon redemption of certain securities and for other
corporate purposes.
 
                                  SECURITIES
 
  The Senior Notes may be issued in one or more series (i) secured by the
Company's first mortgage bonds issued under either or both of the Company's
current mortgage indentures or (ii) following the Substitution Date (as
defined below), as either unsecured senior notes or as senior notes secured by
the Company's first mortgage bonds issued under a mortgage indenture other
than the Company's current mortgage indentures. On the Substitution Date, any
outstanding Senior Notes secured by the Company's first mortgage bonds when
issued will cease to be secured by first mortgage bonds issued under either of
the Company's current mortgage indentures and, at the Company's option, either
(a) will become unsecured general obligations of the Company or (b) will be
secured by first mortgage bonds issued under a mortgage indenture other than
the Company's current mortgage indentures.
 
  Senior Notes will be issued under an indenture (the "Senior Note
Indenture"), the form of which is an exhibit to the Registration Statement,
between the Company and State Street Bank and Trust Company, as trustee (the
"Senior Note Trustee"), and are described below under the caption "Description
of Senior Notes." Prior to the Substitution Date, first mortgage bonds
securing the Senior Notes (the "Pledged Bonds") will be issued under either
(a) the Fortieth Supplemental Indenture, dated September 1, 1954, as
heretofore supplemented and amended by supplemental trust indentures and a new
supplemental trust indenture for each such series of Pledged Bonds issued
thereunder (such Fortieth Supplemental Indenture, as supplemented and as to be
supplemented, is herein referred to as the "Electric Utility Mortgage"), all
from the Company to State Street Bank and Trust Company, as successor trustee
(the "Electric Utility Mortgage Trustee") or (b) the Indenture of First
Mortgage, dated April 1, 1957, as heretofore supplemented and amended by
supplemental trust indentures and a new supplemental trust indenture for each
such series of Pledged Bonds issued thereunder (such Indenture of First
Mortgage, as supplemented and as to be supplemented is herein referred to as
the "Gas Utility Mortgage"), all from the Company, as successor to Washington
Natural Gas Company, to Harris Trust and Savings Bank, Chicago, Illinois, as
trustee (the "Gas Utility Mortgage Trustee"). The Pledged Bonds to be issued
under the Electric Utility Mortgage (the "Pledged Electric Bonds") are
described below under the caption "Pledged Electric Bonds and Electric Utility
Mortgage." The Pledged Bonds to be issued under the Gas Utility Mortgage (the
"Pledged Gas Bonds") are described below under the caption "Pledged Gas Bonds
and Gas Utility Mortgage."
 
  There is no requirement, under either the Senior Note Indenture, the
Electric Utility Mortgage or the Gas Utility Mortgage (collectively, the
"Indentures"), that future issues of debt securities of the Company be issued
under the Indentures, and, subject to certain restrictions following the
Substitution Date which are described in "Description of Senior Notes--
Limitations on Liens" and "--Limitations on Sale-Leaseback Transactions," the
Company will be free to employ other indentures or documentation, containing
provisions different from those included in the Indentures or applicable to
one or more issues of Senior Notes, in connection with future issues of such
other debt securities.

                          DESCRIPTION OF SENIOR NOTES
 
GENERAL
 
  The following summaries of certain provisions of the Senior Note Indenture
do not purport to be complete and are subject to, and qualified in their
entirety by, all of the provisions of the Senior Note Indenture which is
incorporated herein by this reference and the form of which is an exhibit to
the Registration Statement of which this Prospectus is a part. References to
Section numbers under this caption are references to the Section numbers of
the Senior Note Indenture.
 
  Until the Substitution Date (as defined below), the Senior Notes will be
secured by one or more series of Pledged Bonds issued under either the
Electric Utility Mortgage or the Gas Utility Mortgage and delivered by the
Company to the Senior Note Trustee. See "--Security; Substitution Date." ON
THE SUBSTITUTION DATE (AS DEFINED BELOW), THE SENIOR NOTES WILL CEASE TO BE
SECURED BY THE PLEDGED BONDS AND, AT THE COMPANY'S OPTION, EITHER (I) WILL
BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (II) WILL BE SECURED BY
FIRST MORTGAGE BONDS (THE "SUBSTITUTED PLEDGED BONDS") ISSUED UNDER A MORTGAGE
INDENTURE OTHER THAN THE ELECTRIC UTILITY MORTGAGE OR THE GAS UTILITY MORTGAGE
(A "SUBSTITUTED MORTGAGE"). The Senior Note Indenture provides that, in
addition to the Senior Notes offered hereby, additional Senior Notes may be
issued thereunder, without limitation as to aggregate principal amount,
provided that, prior to the Substitution Date, the amount of Senior Notes that
may be issued cannot exceed the aggregate principal amount of first mortgage
bonds that the Company is able to issue under its Electric Utility Mortgage
and its Gas Utility Mortgage. See "Pledged Electric Bonds and Electric Utility
Mortgage--Issuance of Pledged Electric Bonds and Withdrawal of Cash Deposited
Against Such Issuance" and "Pledged Gas Bonds and Gas Utility Mortgage--
Issuance of Pledged Gas Bonds and Withdrawal of Cash Deposited Against Such
Issuance."
 
  The Senior Note Indenture provides that the Senior Notes will be issued in
one or more series, may be issued at various times, may have differing
maturity dates and may bear interest at differing rates. The Prospectus
Supplement applicable to each series of Senior Notes will set forth any
variation in the terms and provisions of such Senior Notes and the related
series of Pledged Bonds from those described in this Prospectus. Unless
otherwise indicated in the applicable Prospectus Supplement, the Senior Notes
will be denominated in United States currency in minimum denominations of
$1,000 and integral multiples thereof.
 
  Unless otherwise indicated in the applicable Prospectus Supplement, there
are no provisions in the Senior Note Indenture or the Senior Notes that
require the Company to redeem, or permit the holders to cause a redemption of,
the Senior Notes or that otherwise protect the holders in the event that the
Company incurs substantial additional indebtedness (except for certain
restrictions on the Company's ability to create, assume or incur certain liens
or to enter into certain financing transactions after the Substitution Date,
as described in "--Limitations on Liens" and "--Limitations on Sale-Leaseback
Transactions"), whether or not in connection with a change in control of the
Company. However, any change in control transaction that involves the
incurrence of additional long-term indebtedness (as notes, first mortgage
bonds or otherwise) by the Company in such a transaction would require
approval of state utility regulatory authorities and, possibly, of federal
utility regulatory authorities.
 
REGISTRATION, TRANSFER AND EXCHANGE
 
  Senior Notes of any series will be exchangeable for other Senior Notes of
the same series of any authorized denominations and of a like aggregate
principal amount and tenor. (Section 2.06).
 
  Unless otherwise indicated in the applicable Prospectus Supplement, Senior
Notes may be presented for registration of transfer (duly endorsed or
accompanied by a duly executed written instrument of transfer), at the office
of the Senior Note Trustee maintained for such purpose with respect to any
series of Senior Notes and referred to in the applicable Prospectus
Supplement, without service charge and upon payment of any taxes and other
governmental charges as described in the Senior Note Indenture. Such transfer
or exchange will be effected upon being satisfied with the documents of title
and indemnity of the person making the request. (Sections 2.06 and 2.07).
 
                                       6
<PAGE>
 
  In the event of any redemption of Senior Notes of any series, the Senior
Note Trustee will not be required to exchange or register a transfer of any
Senior Notes of such series selected, called or being called for redemption
except, in the case of any Senior Note to be redeemed in part, the portion
thereof not to be so redeemed. (Section 2.06). See "Book-Entry System."
 
PAYMENT AND PAYING AGENTS
 
  Principal of and interest and premium, if any, on Senior Notes issued in the
form of Global Notes will be paid in the manner described below under the
caption "Book-Entry System." Unless otherwise indicated in the applicable
Prospectus Supplement, interest on Senior Notes that are in the form of
certificated securities will be paid by wire transfer of clearinghouse funds
or by check mailed to the person entitled thereto at such person's address as
it appears in the register for the Senior Notes maintained by the Senior Note
Trustee; however, a holder of Senior Notes of one or more series under the
Senior Note Indenture in the aggregate principal amount of $10,000,000 or more
having the same interest payment dates will be entitled to receive payments of
interest on such series by wire transfer of immediately available funds to a
bank if appropriate wire transfer instructions have been received by the
Senior Note Trustee on or prior to the applicable regular record date.
(Section 2.12). Unless otherwise indicated in the applicable Prospectus
Supplement, the principal of, and interest at maturity and premium, if any, on
Senior Notes in the form of certificated securities will be payable in
immediately available funds at the office of the Senior Note Trustee. (Section
2.12).
 
  All moneys paid by the Company to a paying agent for the payment of
principal of, interest or premium, if any, on any Senior Note which remain
unclaimed at the end of one year after such principal, interest or premium
shall have become due and payable will be repaid to the Company and the holder
of such Senior Note will thereafter look only to the Company for payment
thereof. (Section 5.04).
 
SECURITY; SUBSTITUTION DATE
 
  Until the Substitution Date (as defined below), the Senior Notes will be
secured by one or more series of the Pledged Electric Bonds and/or by one or
more series of the Pledged Gas Bonds issued and delivered by the Company to
the Senior Note Trustee. See "Pledged Electric Bonds and Electric Utility
Mortgage" and "Pledged Gas Bonds and Gas Utility Mortgage." Upon the issuance
of Senior Notes prior to the Substitution Date, the Company will
simultaneously issue and deliver to the Senior Note Trustee, as security for
such Senior Notes, Pledged Electric Bonds or Pledged Gas Bonds. (Sections 4.01
and 4.08). Such Pledged Bonds will have the same stated rate or rates of
interest (or interest calculated in the same manner), interest payment dates,
stated maturity date and redemption provisions, and will be in the same
aggregate principal amount as the Senior Notes being issued. (Section 4.09).
The Company's obligations to make payments with respect to the principal of,
premium or interest on the Pledged Bonds will be fully or partially, as the
case may be, satisfied and discharged to the extent that, at the time that any
such payment shall be due, the then due principal of, premium or interest on
the related issue of Senior Notes shall have been fully or partially paid or
there shall have been deposited with the Senior Note Trustee pursuant to the
Senior Note Indenture sufficient available funds to fully or partially pay the
then due principal of, premium or interest on such Senior Notes. (Section
2.12).
 
  THE "SUBSTITUTION DATE" WILL BE THE DATE THAT ALL FIRST MORTGAGE BONDS OF
THE COMPANY ISSUED AND OUTSTANDING UNDER THE ELECTRIC UTILITY MORTGAGE
("ELECTRIC BONDS"), OTHER THAN PLEDGED ELECTRIC BONDS, AND, IF ANY PLEDGED GAS
BONDS ARE THEN HELD BY THE SENIOR NOTE TRUSTEE, ALL FIRST MORTGAGE BONDS OF
THE COMPANY ISSUED AND OUTSTANDING UNDER THE GAS UTILITY MORTGAGE ("GAS BONDS"
AND, TOGETHER WITH THE ELECTRIC BONDS, THE "FIRST MORTGAGE BONDS"), OTHER THAN
PLEDGED GAS BONDS, HAVE BEEN RETIRED (AT, BEFORE OR AFTER THE MATURITY
THEREOF) THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE ELECTRIC
BONDS DEEMED TO BE PAID WITHIN THE MEANING OF THE ELECTRIC UTILITY MORTGAGE
AND THOSE GAS BONDS DEEMED TO BE PAID WITHIN THE MEANING OF THE GAS UTILITY
MORTGAGE). ON THE SUBSTITUTION DATE, THE SENIOR NOTE TRUSTEE WILL DELIVER TO
THE COMPANY FOR CANCELLATION ALL PLEDGED BONDS, AND THE COMPANY WILL CAUSE THE
SENIOR NOTE TRUSTEE TO PROVIDE NOTICE TO ALL HOLDERS OF SENIOR NOTES OF THE
OCCURRENCE OF THE SUBSTITUTION DATE. AS A RESULT, ON THE SUBSTITUTION DATE,
THE PLEDGED BONDS WILL CEASE TO SECURE THE SENIOR NOTES, AND, AT THE
 
                                       7
<PAGE>
 
OPTION OF THE COMPANY, THE SENIOR NOTES EITHER (I) WILL BECOME UNSECURED
GENERAL OBLIGATIONS OF THE COMPANY OR (II) WILL BE SECURED BY SUBSTITUTED
PLEDGED BONDS. (Section 4.11). Each issue of Pledged Bonds will be an issue of
Electric Bonds or Gas Bonds of the Company, all of which are secured by a lien
on certain property owned by the Company. In certain circumstances prior to
the Substitution Date, the Company is permitted to reduce the aggregate
principal amount of an issue of Pledged Bonds held by the Senior Note Trustee,
but in no event to an amount lower than the aggregate outstanding principal
amount of the Senior Notes initially issued contemporaneously with such
Pledged Bonds. (Section 4.07). Following the Substitution Date, the Company
will cause the Electric Utility Mortgage and the Gas Utility Mortgage to be
closed, and the Company will not issue any additional bonds under either such
Indenture. (Section 4.10).
 
LIMITATIONS ON LIENS
 
  Under the terms of the Senior Note Indenture, the Company may not issue any
First Mortgage Bonds other than Pledged Bonds, and the Company will be
precluded after the Substitution Date from issuing additional Electric Bonds
or Gas Bonds. In addition, except as described below and unless Substituted
Pledged Bonds are issued to secure the Senior Notes, after the Substitution
Date the Company may not create, assume or incur any mortgage, pledge, lien or
security interest (collectively referred to in this section and under "--
Limitations on Sale-Leaseback Transactions" as "mortgages") upon any real
property interest or other depreciable asset which is used in the Company's
electric or gas utility business, whether owned at the Substitution Date or
thereafter acquired, to secure any indebtedness for money borrowed other than
indebtedness with maturities of twelve months or less ("Debt"), without
effectively securing all Senior Notes (other than such Senior Notes, if any,
which shall by their terms be expressly excluded from such provision) equally
and ratably with such Debt; provided, however, that this restriction will not
apply to:
 
    (a) mortgages on any property existing at the time of the property's
  acquisition (but excluding any extension of or addition to such property
  unless the terms of the mortgage as of the date of acquisition of such
  property provide that such mortgage shall be secured by such extensions or
  additions);
 
    (b) mortgages to secure the payment of all or part of the purchase price
  of property or to secure any Debt incurred prior to, at the time of or
  within 180 days after the acquisition of such property for the purpose of
  financing all or part of the purchase price of such property;
 
    (c) mortgages secured by property used in the generation of electricity;
 
    (d) mortgages existing as of the date of the Senior Note Indenture;
 
    (e) certain permitted encumbrances similar to the permitted encumbrances
  under the Electric Utility Mortgage;
 
    (f) any extension, renewal or replacement (or successive extensions,
  renewals or replacements), in whole or in part, of any mortgage referred to
  in clauses (a) through (e); provided, however, that the principal amount of
  Debt secured thereby may not exceed the principal amount of Debt (plus any
  premium or fee payable in connection with such extension, renewal or
  replacement) so secured at the time of such extension, renewal or
  replacement; and provided, further, that such mortgage must be limited to
  all or such part of the property which was subject to the mortgage so
  extended, renewed or replaced (plus improvements on such property);
 
    (g) mortgages in favor of the United States, any State thereof, any other
  country or any political subdivision of any of the foregoing, to secure
  partial, progress, advance or other payments under any contract or statute;
  or
 
    (h) mortgages securing industrial development, pollution control or
  similar revenue bonds.
 
  Notwithstanding the foregoing restriction, the Company may create, assume or
incur any mortgage not excepted above without equally and ratably securing the
Senior Notes if the aggregate amount of all Debt then outstanding and secured
by such mortgage or any other mortgage not excepted above, together with all
net sale
 
                                       8
<PAGE>
 
proceeds from Sale-Leaseback Transactions (as defined below) which are not
described in clause (i) or (ii) under "--Limitations on Sale-Leaseback
Transactions" below, does not exceed 15% of the Company's total consolidated
capitalization as shown on its latest audited consolidated balance sheet.
(Section 6.07).
 
LIMITATIONS ON SALE-LEASEBACK TRANSACTIONS
 
  Except as described below and unless Substituted Pledged Bonds are issued to
secure the Senior Notes, from and after the Substitution Date the Company may
not sell or transfer any real property interest or other depreciable asset,
with the Company taking back a lease of such property (any such transaction, a
"Sale-Leaseback Transaction"), unless (i) such Sale-Leaseback Transaction
occurs within 180 days after the later of the date of acquisition of such
property or the date of the completion of construction or commencement of full
operations on such property or (ii) within 120 days after such Sale-Leaseback
Transaction, the Company applies or causes to be applied to the retirement of
Debt of the Company (other than Debt which is subordinate in right of payment
to the Senior Notes) an amount not less than the net proceeds of the sale of
such property. (Section 6.07)
 
  Notwithstanding the foregoing restriction, the Company may effect any Sale-
Leaseback Transaction not excepted above if the net sale proceeds from such
Sale-Leaseback Transaction, together with the net sale proceeds from all other
Sale-Leaseback Transactions not excepted above and all Debt then outstanding
and secured by mortgages not described in any of clauses (a) through (h) under
"--Limitations on Liens," does not exceed 15% of the Company's total
consolidated capitalization as shown on its latest audited consolidated
balance sheet. The Company may also effect any Sale-Leaseback Transaction
involving a lease for a period, including renewals, of not more than 36
months. (Section 6.07).
 
EVENTS OF DEFAULT
 
  The following constitute events of default under the Senior Note Indenture:
(a) default in the payment of principal or premium, if any, on any Senior Note
when due and payable and continuance of such default for five days; (b)
default in the payment of interest on any Senior Note when due which continues
for 30 days; (c) default in the performance or breach of any other covenant or
warranty of the Company in the Senior Note Indenture and the continuation
thereof for 90 days after written notice to the Company as provided in the
Senior Note Indenture; (d) prior to the Substitution Date, the occurrence of a
default under the Electric Utility Mortgage, of which default the Electric
Utility Mortgage Trustee or the holders of a majority in aggregate principal
amount of the outstanding Senior Notes have given written notice to the Senior
Note Trustee; (e) prior to the Substitution Date, the occurrence of a default
under the Gas Utility Mortgage, of which default the Gas Utility Mortgage
Trustee or the holders of a majority in aggregate principal amount of the
outstanding Senior Notes have given written notice to the Senior Note Trustee;
(f) if any Substituted Pledged Bonds are outstanding, the occurrence of a
default under the Substituted Mortgage, of which default the trustee under
such Substituted Mortgage or the holders of a majority in aggregate principal
amount of the outstanding Senior Notes have given written notice to the Senior
Note Trustee; and (g) certain events of bankruptcy, insolvency or
reorganization of the Company. (Section 8.01).
 
  If an event of default occurs and is continuing, either the Senior Note
Trustee or the holders of a majority in principal amount of the outstanding
Senior Notes may declare the principal amount of all Senior Notes to be due
and payable immediately. Upon such acceleration of the Senior Notes, the
Senior Note Trustee is empowered to cause the mandatory redemption of the
Pledged Bonds or Substituted Pledged Bonds under the terms of the Electric
Utility Mortgage, Gas Utility Mortgage or the Substituted Mortgage, as the
case may be. At any time after an acceleration of the Senior Notes has been
declared, but before a judgment or decree for the immediate payment of the
principal amount of the Senior Notes has been obtained, and so long as all
first mortgage bonds have not been accelerated, if the Company pays or
deposits with the Senior Note Trustee a sum sufficient to pay all matured
installments of interest, the principal and any premium which has become due
otherwise than by acceleration and any other amounts due the Senior Note
Trustee, and all defaults shall have been cured or waived, then such payment
or deposit will cause an automatic rescission and annulment of the
acceleration of the Senior Notes. (Section 8.01).
 
                                       9
<PAGE>
 
  The Senior Note Indenture provides that the Senior Note Trustee generally
will be under no obligation to exercise any of its rights or powers under the
Senior Note Indenture at the request or direction of any of the holders unless
such holders have offered to the Senior Note Trustee reasonable security or
indemnity against the liabilities and costs which may be incurred by such
exercise. (Section 9.02). The holders of a majority in principal amount of the
outstanding Senior Notes generally will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Senior Note Trustee, or of exercising any trust or power conferred on the
Senior Note Trustee, with respect to the Senior Notes. (Section 8.07). Each
holder of any Senior Note has the right to institute a proceeding with respect
to the Senior Note Indenture, but such right is subject to certain conditions
precedent specified in the Senior Note Indenture. (Section 8.04). The Senior
Note Indenture provides that the Senior Note Trustee, within 90 days after the
occurrence of a default with respect to the Senior Notes, is required to give
the holders of the Senior Notes notice of such default, unless cured or
waived, but, except in the case of default in the payment of principal of, or
premium, if any, or interest on any Senior Notes, the Senior Note Trustee may
withhold such notice if it determines in good faith that it is in the interest
of such holders to do so. (Section 8.08). The Company is required to deliver
to the Senior Note Trustee each year a certificate as to whether or not, to
the knowledge of the officers signing such certificate, the Company is in
compliance with the conditions and covenants under the Senior Note Indenture.
(Section 6.06).
 
MODIFICATION
 
  Modification and amendment of the Senior Note Indenture may be effected by
the Company and the Senior Note Trustee with the consent of the holders of a
majority in principal amount of the outstanding Senior Notes affected thereby,
provided that no such modification or amendment may, without the consent of
the holder of each outstanding Senior Note affected thereby, (a) change the
maturity date of any Senior Note; (b) reduce the rate or extend the time of
payment of interest on any Senior Note; (c) reduce the principal amount of, or
premium payable on, any Senior Note; (d) change the coin or currency of any
payment of principal of, or any premium or interest on, any Senior Note; (e)
change the date on which any Senior Note may be redeemed or adversely affect
the rights of a holder to institute suit for the enforcement of any payment on
or with respect to any Senior Note; (f) impair the interest of the Senior Note
Trustee in the Pledged Bonds or Substituted Pledged Bonds held by it or, prior
to the Substitution Date, reduce the principal amount of any issue of Pledged
Bonds or Substituted Pledged Bonds securing the Senior Notes to an amount less
than the principal amount of the related issue of Senior Notes or alter the
payment provisions of such Pledged Bonds or Substituted Pledged Bonds in a
manner adverse to the holders of the Senior Notes; or (g) modify the foregoing
requirements or reduce the percentage of outstanding Senior Notes necessary to
modify or amend the Senior Note Indenture or to waive any past default to less
than a majority. Modification and amendment of the Senior Note Indenture may
be effected by the Company and the Senior Note Trustee without the consent of
the holders (a) to add to the covenants of the Company for the benefit of the
holders or to surrender a right conferred on the Company in the Senior Note
Indenture; (b) to add further security for the Senior Notes; (c) to make
certain other modifications, generally of a ministerial or immaterial nature;
or (d) to make certain other modifications which are not prejudicial to the
interests of the holders of the Senior Notes. (Sections 13.01 and 13.02).
 
DEFEASANCE AND DISCHARGE
 
  The Senior Note Indenture provides that the Company will be discharged from
any and all obligations in respect to the Senior Notes and the Senior Note
Indenture (except for certain obligations such as obligations to register the
transfer or exchange of Senior Notes, replace stolen, lost or mutilated Senior
Notes and maintain paying agencies) if, among other things, the Company
irrevocably deposits with the Senior Note Trustee, in trust for the benefit of
holders of Senior Notes, money or certain United States government
obligations, or any combination thereof, which through the payment of interest
thereon and principal thereof in accordance with their terms will provide
money in an amount sufficient, without reinvestment, to make all payments of
principal of, and any premium and interest on, the Senior Notes on the dates
such payments are due in accordance with the terms of the Senior Note
Indenture and the Senior Notes provided that, unless all of the Senior Notes
are to be due within 90 days of such deposit by redemption or otherwise, the
Company shall also have delivered to the
 
                                      10
<PAGE>
 
Senior Note Trustee an opinion of counsel to the effect that the holders of
the Senior Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such defeasance or discharge of the Senior Note
Indenture. Thereafter, the holders of Senior Notes must look only to such
deposit for payment of the principal of, and interest and any premium on, the
Senior Notes. (Section 5.01).
 
CONSOLIDATION, MERGER AND SALE OR DISPOSITION OF ASSETS
 
  The Company will not consolidate with or merge into any other corporation or
sell, transfer or otherwise dispose of all or substantially all its assets
unless the successor or transferee corporation assumes by supplemental
indenture the due and punctual payment of the principal of and premium and
interest on all the Senior Notes and the performance of every covenant of the
Senior Note Indenture to be performed or observed by the Company and (i) if
such transaction occurs prior to the Substitution Date, unless the successor
or transferee corporation assumes the Company's obligations under the Electric
Utility Mortgage and the Gas Utility Mortgage with respect to the Pledged
Bonds, or (ii) if such transaction occurs on or after the Substitution Date
and Substituted Pledged Bonds are outstanding, unless the successor or
transferee corporation assumes the Company's obligations under the Substituted
Mortgage with respect to the Substituted Pledged Bonds. Upon any such
consolidation, merger, sale, transfer or other disposition of all or
substantially all of the assets of the Company, the successor corporation
formed by such consolidation or into which the Company is merged or to which
such transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Senior Note Indenture
with the same effect as if such successor corporation had been named as the
Company therein and the Company will be released from all obligations under
the Senior Note Indenture. The Senior Note Indenture defines "all or
substantially all" of the assets of the Company as being 50% or more of the
total assets of the Company as shown on the balance sheet of the Company as of
the end of the prior year and specifically permits any such sale, transfer or
other disposition during a calendar year of less than 50% of total assets
without the consent of the holders of the Senior Notes and without the
assumption by the transferee of the Company's obligations on the Senior Notes
and covenants contained in the Senior Note Indenture. (Sections 12.01 and
12.02).
 
VOTING OF PLEDGED BONDS HELD BY SENIOR NOTE TRUSTEE
 
  The Senior Note Trustee, as a holder of Pledged Electric Bonds and/or
Pledged Gas Bonds, will attend any meeting of bondholders under the Electric
Utility Mortgage or the Gas Utility Mortgage, as the case may be, as to which
it receives due notice, or, at its option, will deliver its proxy in
connection therewith. Either at such meeting, or otherwise where the consent
of holders of Electric Bonds or Gas Bonds is sought without a meeting, the
Senior Note Trustee will vote all of the Pledged Electric Bonds or Pledged Gas
Bonds held by it, or will consent with respect thereto, as directed by the
holders of a majority in aggregate principal amount of the outstanding Senior
Notes; provided, however, that the Senior Note Trustee shall not be required
to vote the Pledged Bonds of any particular issue in favor of, or give consent
to, any action except upon notification by the Senior Note Trustee to the
holders of the related issue of Senior Notes of such proposal and consent
thereto of the holders of a majority in principal amount of the outstanding
Senior Notes of such issue. (Section 4.03).
 
RESIGNATION OR REMOVAL OF SENIOR NOTE TRUSTEE
 
  The Senior Note Trustee may resign at any time upon written notice to the
Company specifying the day upon which the resignation is to take effect and
such resignation will take effect immediately upon the later of the
appointment of a successor Senior Note Trustee and such specified day.
(Section 9.10).
 
  The Senior Note Trustee may be removed at any time by an instrument or
concurrent instruments in writing filed with the Senior Note Trustee and
signed by the holders, or their attorneys-in-fact, of at least a majority in
principal amount of the then outstanding Senior Notes. In addition, so long as
no event of default or event which,
 
                                      11
<PAGE>
 
with the giving of notice or lapse of time or both, would become an event of
default has occurred and is continuing, the Company may remove the Senior Note
Trustee upon notice to the holder of each Senior Note outstanding and the
Senior Note Trustee, and appointment of a successor Senior Note Trustee.
(Section 9.10).
 
CONCERNING THE SENIOR NOTE TRUSTEE
 
  State Street Bank and Trust Company is the Senior Note Trustee under the
Senior Note Indenture. The Senior Note Trustee also acts as trustee for the
Company's Electric Bonds. Though the Company does not currently maintain any
other banking relationships with the Senior Note Trustee in the ordinary course
of business, it may choose to do so in the future.

             PLEDGED ELECTRIC BONDS AND ELECTRIC UTILITY MORTGAGE
 
GENERAL
 
  The Pledged Electric Bonds issued as security for Senior Notes will be
series of Electric Bonds issued under the Electric Utility Mortgage and a new
supplemental trust indenture for each such series of Pledged Electric Bonds,
all from the Company to the Electric Utility Mortgage Trustee. Copies of the
Electric Utility Mortgage and the form of supplemental indenture for the
Pledged Electric Bonds are filed as exhibits to the Registration Statement of
which this Prospectus is a part. The following summaries of certain provisions
of the Electric Utility Mortgage do not purport to be complete and are subject
to, and qualified in their entirety by, the detailed provisions of the
Electric Utility Mortgage which are incorporated herein by this reference.
References to Article and Section numbers under this caption are references to
Article and Section numbers of the Electric Utility Mortgage unless otherwise
indicated. Unless the context indicates otherwise, words or phrases defined in
the Electric Utility Mortgage are capitalized and used with the same meanings
under this caption.
 
TERMS OF PLEDGED ELECTRIC BONDS
 
  Pledged Electric Bonds will be issued to the Senior Note Trustee. Each issue
of Pledged Electric Bonds to the Senior Note Trustee will be in a principal
amount equal to the principal amount of the Senior Notes issued
contemporaneously with such Pledged Electric Bonds. The Company's obligations
to make payments with respect to the principal of, premium or interest on the
Pledged Electric Bonds will be fully or partially, as the case may be,
satisfied and discharged to the extent that, at the time that any such payment
shall be due, the then due principal of, premium or interest on the related
issue of Senior Notes shall have been fully or partially paid or there shall
have been deposited with the Senior Note Trustee pursuant to the Senior Note
Indenture sufficient available funds to fully or partially pay the then due
principal of, premium or interest on such Senior Notes. The Pledged Electric
Bonds will be exchangeable for a like aggregate principal amount of Pledged
Electric Bonds of the same series of other authorized denominations at the
office of the Electric Utility Mortgage Trustee in Boston, Massachusetts,
without payment of any charge other than for any stamp tax or other
governmental charge incidental thereto.
 
  The Electric Utility Mortgage does not contain any covenants or other
provisions that are specifically intended to afford holders of the Pledged
Electric Bonds special protection in the event of a highly leveraged
transaction.
 
  The Prospectus Supplement applicable to each series of Senior Notes will set
forth any variation in the terms and provisions of the related series of
Pledged Electric Bonds, if any, from those described in this Prospectus. Each
issue of Pledged Electric Bonds will have the same stated rate or rates of
interest (or interest calculated in the same manner), interest payment dates,
stated maturity date and redemption provisions, and will be in the same
aggregate principal amount, as the related issue of Senior Notes.
 
DEPRECIATION FUND
 
  The Company will pay cash or deliver Electric Bonds of any series to the
Electric Utility Mortgage Trustee by May 31 of each year in an amount equal to
the minimum provision for depreciation for the preceding year (i.e., an amount
by which 15% of gross utility operating revenues of the Company, after
deducting cost of electricity purchased and rental and lease payments, exceeds
maintenance, repairs and renewals). Cash held in the depreciation fund may be
applied to the retirement of the Electric Bonds of certain of the Secured
Medium-Term Notes, Series A, certain of the Secured Medium-Term Notes, Series
B, the 7.05% Series due 2021, the 7.25% Series due 2021 and the 6.80% Series
due 2022 (the last three series were issued as collateral for City of Forsyth,
Rosebud County, Montana, Pollution Control Revenue Refunding Bonds) at a price
not exceeding the applicable Regular Redemption Price thereof, or other
Electric Bonds at a price not exceeding the applicable Special Redemption
Price thereof. In lieu of paying cash or delivering Electric Bonds, the
Company will have the option of satisfying this obligation through the use of
unfunded property additions or unfunded Electric Bond
 
                                      13
<PAGE>
 
credits, or both. Cash and Electric Bonds held in such fund may also be
withdrawn by using either of the aforesaid credits. (Section Four, Article II,
Part I). For information on the proposed modification of the depreciation fund
requirements, see "--Consent by Holders of the Pledged Electric Bonds to
Modification of Mortgage."
 
TITLES AND KIND AND PRIORITY OF LIEN
 
  The Pledged Electric Bonds are to be secured equally and ratably with all
other Electric Bonds heretofore or hereafter issued under the Electric Utility
Mortgage by a valid and direct first mortgage of the Company's electric
utility property, and on its electric franchises and permits, except as stated
below and subject only to permitted encumbrances. (Granting Clauses).
 
  The Electric Utility Mortgage permits the Company to acquire utility
property subject to certain prior liens. The Electric Utility Mortgage
requires that there shall be subjected to the lien thereof (subject to certain
liabilities in cases of mergers and consolidations) all utility property
(other than excepted property) which the Company may hereafter acquire.
(Granting Clauses of the Electric Utility Mortgage and Sections 9.06, 9.10 and
14.04). The lien of the Electric Utility Mortgage is subject to the lien of
the Gas Utility Mortgage with respect to the gas utility property of WNG
acquired in connection with the Merger, as well as all substitutions,
replacements, additions, betterments, developments, extensions and
enlargements to, of or upon such gas utility property. (Sections 9.07, 9.10
and 14.05 of the Electric Utility Mortgage and Section 14.03 of the Gas
Utility Mortgage). See "Pledged Gas Bonds and Gas Utility Mortgage--Titles and
Kind and Priority of Lien."
 
  There are excepted from the lien of the Electric Utility Mortgage: cash,
securities, notes, accounts receivable and similar instruments; conditional
sales, appliance rental or lease agreements; materials and supplies;
merchandise held for the purpose of sale, lease or distribution; fuel
(including fissionable material) and personal property consumable in
operations; oil, gas and other minerals and timber under or upon lands of the
Company; office furniture and equipment, automobiles and similar
transportation equipment; nonutility property and certain property of a
successor corporation in a merger or consolidation. (Section 20.01).
 
DIVIDEND RESTRICTION
 
  So long as any of the Electric Bonds are outstanding, the Company shall not
(i) declare or pay any dividends (other than dividends payable in the
Company's common stock) or make any other distribution on any shares of its
common stock or (ii) purchase, redeem or otherwise retire for consideration
any shares of stock except out of net income available for dividends on its
common stock (as defined), accumulated after December 31, 1957, plus the sum
of $7,500,000. (Section 1.05 of the Forty-fourth Supplemental Indenture to the
Electric Utility Mortgage).
 
ISSUANCE OF ELECTRIC BONDS AND WITHDRAWAL OF CASH DEPOSITED AGAINST SUCH
ISSUANCE
 
  The principal amount of Electric Bonds which may be issued under the
Electric Utility Mortgage is not limited, provided that the issuance tests in
the Electric Utility Mortgage are satisfied. (Section 3.01). Electric Bonds
may be issued from time to time against (i) 60% of unfunded net additions
(Section 5.03), (ii) deposit of cash (Section 5.04) and/or (iii) 100% of
unfunded Electric Bond credits (Section 5.05). The issuance of Electric Bonds
against unfunded net additions, and the issuance of Electric Bonds for other
purposes, with certain exceptions, is subject to net earnings available for
interest being at least two times the annual interest requirement on all
Electric Bonds and prior lien debt to be outstanding. (Section 1.42). Cash
deposited is withdrawable against 60% of unfunded net additions and 100% of
unfunded Electric Bond credits (Sections 8.02 and 8.03).
 
MODIFICATION OF MORTGAGE
 
  The rights of the bondholders under the Electric Utility Mortgage may be
modified with the consent of the holders of 66 2/3% of the Electric Bonds,
including the consent of the holders of 66 2/3% of the Electric Bonds of each
series affected by the proposed modification. In general, no adverse
modification of the terms of payment
 
                                      14
<PAGE>
 
and no modification permitting additional prior or parity liens, or reducing
the percentage of Electric Bonds required for modification, is effective
against any bondholder without the consent of such holder. (Section 18.02).
 
THE ELECTRIC UTILITY MORTGAGE TRUSTEE
 
  The holders of a majority in principal amount of the Electric Bonds have the
right to require the Electric Utility Mortgage Trustee to enforce the Electric
Utility Mortgage, but the Electric Utility Mortgage Trustee is entitled to
receive reasonable indemnity and under certain circumstances is not required
to act (Section 12.20).
 
DEFAULTS AND NOTICES
 
  A default under the Electric Utility Mortgage is defined as (i) failure to
pay the principal and premium when due or interest for 30 days after becoming
due, (ii) failure to satisfy any sinking, improvement or depreciation fund
obligation for 60 days after becoming due, (iii) failure for 90 days after
notice to observe other covenants or conditions, (iv) entry of an order for
reorganization or appointment of a trustee or receiver and continuance of such
order or appointment unstayed for 90 days, (v) certain adjudications,
petitions or consents in bankruptcy, insolvency or reorganization proceedings
and (vi) rendering of a judgment in excess of $100,000 and its continuance
unsatisfied for 90 days. (Section 12.01).
 
  The Electric Utility Mortgage does not require the filing with the Trustee
of any periodic evidence as to the absence of default or as to compliance with
the terms of the Electric Utility Mortgage.
 
CONSENT BY HOLDERS OF THE PLEDGED ELECTRIC BONDS TO MODIFICATION OF FIRST
MORTGAGE INDENTURE
 
  The Company anticipates that its fuel costs may increase in future years as
it utilizes its combustion turbines and other thermal resources. The
offsetting increases in revenues may escalate the minimum provision for
depreciation (15% of operating revenues less certain deductions) out of
proportion to reasonable maintenance and replacement needs. This distortion
would adversely affect the calculation of unfunded net property additions
available for certain purposes under the Electric Utility Mortgage, including
issuance of Pledged Electric Bonds.
 
  In such event, the Company would propose to modify the Electric Utility
Mortgage by reducing the amount of operating revenues used in determining the
minimum provision for depreciation by the amount of fuel costs.
 
  Each supplemental indenture for a new series of Pledged Electric Bonds will
provide that each holder of the Pledged Electric Bonds, by his acceptance
thereof, consents to such modification. This modification has been similarly
consented to by the holders of the Electric Bonds of the Secured Medium-Term
Notes, Series A and the Secured Medium Term Notes, Series B. The Sixty-seventh
Supplemental Indenture to the Electric Utility Mortgage provides that the
trustee holding the Electric Bonds issued under said Supplemental Indenture as
collateral for the Puget Energy, Inc. Guaranteed Collateralized Bonds consents
to such modification on behalf of the holders of such Guaranteed
Collateralized Bonds. The Seventy-second and Seventy-third Supplemental
Indentures to the Electric Utility Mortgage provide that the trustees holding
Electric Bonds issued under said Supplemental Indentures as collateral for
City of Forsyth, Rosebud County, Montana, Pollution Control Revenue Refunding
Bonds consent to such modification on behalf of the holders of such Pollution
Control Revenue Refunding Bonds. The modification will become effective when
consents have been obtained from the holders of 66 2/3% in principal amount of
each other series of Electric Bonds at the time outstanding.

                  PLEDGED GAS BONDS AND GAS UTILITY MORTGAGE
 
GENERAL
 
  The Pledged Gas Bonds issued as security for Senior Notes will be series of
Gas Bonds issued under the Gas Utility Mortgage and a new supplemental trust
indenture for each such series of Pledged Gas Bonds, all from the Company to
the Gas Utility Mortgage Trustee. A copy of the Gas Utility Mortgage is filed
as an exhibit to the Registration Statement of which this Prospectus is a
part. The following summaries of certain provisions of the Gas Utility
Mortgage do not purport to be complete and are subject to, and qualified in
their entirety by, the detailed provisions of the Gas Utility Mortgage which
are incorporated herein by this reference. References to Article and Section
numbers under this caption are references to Article and Section numbers of
the Gas Utility Mortgage unless otherwise indicated. Unless the context
indicates otherwise, words or phrases defined in the Gas Utility Mortgage are
capitalized and used with the same meanings under this caption.
 
TERMS OF PLEDGED GAS BONDS
 
  Pledged Gas Bonds will be issued to the Senior Note Trustee. Each issue of
Pledged Gas Bonds to the Senior Note Trustee will be in a principal amount
equal to the principal amount of the Senior Notes issued contemporaneously
with such Pledged Gas Bonds. The Company's obligations to make payments with
respect to the principal of, premium or interest on the Pledged Gas Bonds will
be fully or partially, as the case may be, satisfied and discharged to the
extent that, at the time that any such payment shall be due, the then due
principal of, premium or interest on the related issue of Senior Notes shall
have been fully or partially paid or there shall have been deposited with the
Senior Note Trustee pursuant to the Senior Note Indenture sufficient available
funds to fully or partially pay the then due principal of, premium or interest
on such Senior Notes. The Pledged Gas Bonds will be exchangeable for a like
aggregate principal amount of Pledged Gas Bonds of the same series of other
authorized denominations at the office of the Gas Utility Mortgage Trustee in
Chicago, Illinois, without payment of any charge other than for any stamp tax
or other governmental charge incidental thereto.
 
  The Gas Utility Mortgage does not contain any covenants or other provisions
that are specifically intended to afford holders of the Pledged Gas Bonds
special protection in the event of a highly leveraged transaction.
 
  The Prospectus Supplement applicable to each series of Senior Notes will set
forth any variation in the terms and provisions of the related series of
Pledged Gas Bonds, if any, from those described in this Prospectus. Each issue
of Pledged Gas Bonds will have the same stated rate or rates of interest (or
interest calculated in the same manner), interest payment dates, maturity date
and redemption provisions, and will be in the same aggregate principal amount,
as the related issue of Senior Notes.
 
RENEWAL FUND
 
  The Company will pay cash and/or deliver Gas Bonds (taken at the principal
amount thereof) to the Gas Utility Mortgage Trustee for deposit into a renewal
fund on or before May 1 of each year in an amount equal to the greater of
 
    (a) the aggregate amount of the minimum provision for depreciation (i.e.,
  an amount computed at the rate of 2% per annum, or such other rate as may
  be permitted or required by the Washington Utilities and Transportation
  Commission, of the book value of depreciable gas utility property subject
  to the lien of the Gas Utility Mortgage and not to prior liens) from March
  1, 1957 to the end of the next preceding calendar year; or
 
    (b) the aggregate amount of retirements for the same period;
 
in excess of the greater of
 
    (i) the aggregate amounts for the minimum provision for depreciation or
  retirements, whichever is greater, shown in the next preceding renewal fund
  certificate filed with the Gas Utility Mortgage Trustee pursuant to the
  requirements of Section 4.04 of the Gas Utility Mortgage; or
 
    (ii) the aggregate amounts for the minimum provision for depreciation or
  retirements, whichever is greater, shown in the latest certificate of
  available net additions delivered to the Gas Utility Mortgage Trustee
  pursuant to Section 2.01 of the Gas Utility Mortgage;
 
                                      16
<PAGE>
 
less the aggregate amount of Gas Bonds retired by sinking fund operations, not
theretofore used as a credit on account of the renewal fund in previous renewal
fund certificates. The renewal fund obligation may be satisfied in whole or in
part by credits consisting of unfunded property additions and/or unfunded Gas
Bond credits. (Section 4.04).
 
  Any cash deposited in the renewal fund, if and to the extent that the Company
at the time does not have property additions available for use as a credit to
satisfy such renewal fund obligation, may, upon the written order of the
Company, be applied by the Gas Utility Mortgage Trustee to the redemption of
certain Gas Bonds or, if not so applied pursuant to the provisions of the Gas
Utility Mortgage, to the retirement of Gas Bonds. (Section 4.04).
 
TITLES AND KIND AND PRIORITY OF LIEN
 
  The Pledged Gas Bonds are to be secured equally and ratably with all other
Gas Bonds heretofore issued under the Gas Utility Mortgage by a valid and
direct first mortgage of the Company's gas utility property (except as stated
below) and on its gas utility franchises and permits and gas purchase contracts
(Section 9.14 and Article Two of the Seventh Supplemental Indenture to the Gas
Utility Mortgage), subject only to permitted encumbrances (Granting Clause VI
and Section 1.39) and certain minor exceptions (Granting Clause IX).
 
  Notwithstanding the foregoing, there is excepted from the lien of the Gas
Utility Mortgage, among other things, all property owned by Puget Sound Power &
Light Company immediately prior to the effective time of the Merger, as well as
any property acquired by the Company after the Merger (except substitutions,
replacements, additions, betterments, developments, extensions and enlargements
to, of or upon the gas utility property owned by WNG at the time of the
Merger). (Section 1.03 of the Thirty-first Supplemental Indenture to the Gas
Utility Mortgage).
 
  The Gas Utility Mortgage permits the Company to acquire gas utility property
subject to prior liens, but such property shall not be deemed to be "property
additions" under the Gas Utility Mortgage unless and until such prior lien is
paid. At such time as title to such property shall vest in the Company free and
clear of such prior lien, then such property shall be subject to the lien of
the Gas Utility Mortgage, subject only to the permitted encumbrances and
exceptions referred to herein (Sections 1.28, 9.07 and 9.10).
 
  There are excepted from the lien of the Gas Utility Mortgage: cash,
securities, notes, accounts receivable and similar instruments; conditional
sales, appliance rental or lease agreements; materials and supplies;
merchandise held for the purpose of sale, lease or distribution; gas or liquid
hydrocarbons in pipe lines and in storage; fuel and personal property
consumable in operations; oil, gas and other minerals and timber under or upon
lands of the Company; office furniture and equipment, automobiles and similar
transportation equipment; nonutility property and certain property of a
successor corporation in a merger or consolidation. (Granting Clause IX).
 
DIVIDEND RESTRICTION
 
  So long as any of the Company's Secured Medium Term Notes, Series C, issued
under the Gas Utility Mortgage, are outstanding, the Company shall not (i)
declare or pay any dividends (other than dividends payable in the Company's
common stock) or make any other distribution on any shares of its common stock
or (ii) purchase, redeem or otherwise retire for consideration any shares of
stock (other than in exchange for, or from the net cash proceeds of, other new
shares of capital stock of the Company and other than any shares of any class
of stock ranking as to dividends or assets prior to the Company's common stock
required to be purchased, redeemed or otherwise retired for any sinking fund or
purchase fund for such class of stock), if the aggregate amount of all such
dividends, distributions and expenditures made since September 30, 1994 would
exceed the aggregate amount of the net income of the Company accumulated after
September 30, 1994 plus the sum of $20,000,000. (Section 1.04 of the Thirtieth
Supplemental Indenture to the Gas Utility Mortgage).
 
                                       17
<PAGE>
 
ISSUANCE OF GAS BONDS AND WITHDRAWAL OF CASH DEPOSITED AGAINST SUCH ISSUANCE
 
  The principal amount of Gas Bonds issuable under the Gas Utility Mortgage is
not limited, provided that the issuance tests in the Gas Utility Mortgage are
satisfied. (Section 3.01). Gas Bonds may be issued from time to time against
(i) 60% of unfunded net additions (Section 5.03); (ii) deposit of cash
(Section 5.04); and/or (iii) 100% of unfunded Gas Bond credits (Section 5.05).
With certain exceptions, the issuance of Gas Bonds is subject to net earnings
available for interest being at least (a) two times the annual interest
requirements on all Gas Bonds and prior lien debt to be outstanding (Section
1.41) and (b) 1.75 times the annual interest charges on all indebtedness of
the Company to be outstanding immediately after such issuance. (Section 1.05
of the Thirtieth Supplemental Indenture to the Gas Utility Mortgage). Cash
deposited is withdrawable against 60% of unfunded net additions in the case of
moneys on deposit with the Gas Utility Mortgage Trustee for the purpose
described in clause (ii) of this paragraph, 100% of the amount of unfunded net
additions in the case of any other trust moneys and 100% of unfunded Gas Bond
credits. (Section 8.02 and 8.03).
 
MODIFICATION OF MORTGAGE
 
  The rights of the bondholders under the Gas Utility Mortgage may be modified
with the consent of the holders of 66 2/3% of the Gas Bonds, including the
consent of the holders of 66 2/3% of the Gas Bonds of each series affected by
the proposed modification. In general, no adverse modification of the terms of
payment and no modification permitting additional prior or parity liens, or
reducing the percentage of Gas Bonds required for modification, is effective
against any bondholder without the consent of such holder. (Section 18.02).
 
THE GAS UTILITY MORTGAGE TRUSTEE
 
  The holders of a majority in principal amount of the Gas Bonds have the
right to require the Gas Utility Mortgage Trustee to enforce the Gas Utility
Mortgage, but the Gas Utility Mortgage Trustee is entitled to receive
reasonable indemnity and under certain circumstances is not required to act.
(Section 12.20).
 
DEFAULTS AND NOTICES
 
  An event of default under the Gas Utility Mortgage is defined as (i) failure
to pay the principal and premium when due, (ii) failure to pay interest for 10
days after becoming due, (iii) failure to satisfy any sinking, renewal,
improvement, maintenance or depreciation fund obligation for 30 days after
becoming due, (iv) failure for 30 days after notice to observe other covenants
or conditions, (v) entry of an order for reorganization or appointment of a
trustee or receiver or for the liquidation of the Company or the attachment of
the Company's property and continuance of such order, appointment or
attachment unstayed for 60 days, (vi) certain adjudications, petitions or
consents in bankruptcy, insolvency or reorganization proceedings, (vii)
failure to pay any part of the principal of, premium, if any, or interest on,
or any other payment of money due under any indebtedness (other than the Gas
Bonds) in an aggregate outstanding amount of $500,000 or more, or the failure
by the Company to perform or observe any other agreement, term or condition
contained in any document evidencing or securing such indebtedness, if the
effect of such failure is to cause, or to permit the holders of such
indebtedness to cause, or permit any other party to such indebtedness to
cause, any payment in respect of such indebtedness to become due prior to its
due date, and (viii) rendering of a judgment in excess of $100,000 and its
continuance unsatisfied for 90 days. (Section 12.01 and Article IV of the
Twenty-second Supplemental Indenture).
 
  The Gas Utility Mortgage does not require the filing with the Gas Utility
Mortgage Trustee of any periodic evidence as to the absence of default or as
to compliance with the terms of the Gas Utility Mortgage.

                               BOOK-ENTRY SYSTEM
 
  Each series of Senior Notes may be issued in the form of one or more Global
Notes representing all or part of such series of Senior Notes and which will
be deposited with or on behalf of the Depository and registered in the name of
the Depository or a nominee of the Depository.
 
  The following is based solely on information furnished by DTC:
 
  Unless otherwise specified in the Prospectus Supplement, DTC will act as
Depository for those Senior Notes issued as Global Notes. The Global Notes
will be issued as fully-registered securities registered in the name of Cede &
Co. (DTC's partnership nominee). DTC is a limited-purpose trust company
organized under the New York Banking Law, a "banking organization" within the
meaning of the New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Securities Exchange Act of 1934. DTC holds securities that its
participants ("Participants") deposit with DTC. DTC also facilitates the
settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-
entry changes in Participants' accounts, thereby eliminating the need for
physical movement of securities certificates. "Direct Participants" include
securities brokers and dealers, banks, trust companies, clearing corporations,
and certain other organizations. DTC is owned by a number of its Direct
Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc., and the National Association of Securities Dealers, Inc.
Access to the DTC system is also available to others such as securities
brokers and dealers, banks, and trust companies that clear through or maintain
a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the Commission.
 
  Purchases of the Senior Notes under the DTC system must be made by or
through Direct Participants, which will receive a credit for the Senior Notes
on DTC's records. The ownership interest of each actual purchaser of each
Security ("Beneficial Owner") is in turn to be recorded on the Direct and
Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchase, but Beneficial Owners are expected to
receive written confirmation providing details of the transaction, as well as
periodic statements of their holdings, from the Direct or Indirect Participant
through which the Beneficial Owner entered into the transaction. Transfers of
ownership interests in the Senior Notes are to be accomplished by entries made
on the books of Participants acting on behalf of Beneficial Owners. Beneficial
Owners will not receive certificates representing their ownership interests in
the Senior Notes, except in the event that use of the book-entry system for
the Senior Notes is discontinued.
 
  To facilitate subsequent transfers, all securities deposited by Participants
with DTC are registered in the name of DTC's partnership nominee, Cede & Co.
The deposit of the Senior Notes with DTC and their registration in the name of
Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of
the actual Beneficial Owners of the Senior Notes; DTC's records reflect only
the identity of the Direct Participants to whose accounts such Senior Notes
are credited, which may or may not be the Beneficial Owners. The Participants
will remain responsible for keeping account of the holdings on behalf of their
customers.
 
  Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.
 
  If the Global Notes are redeemable, redemption notices shall be sent to Cede
& Co. If less than all of the Global Notes are being redeemed, DTC's practice
is to determine by lot the amount of the interest of each Direct Participant
in such issue to be redeemed.
 
  Neither DTC nor Cede & Co. will consent or vote with respect to the Senior
Notes. Under its usual procedures, DTC mails an Omnibus Proxy to the Company
as soon as possible after the record date. The
 
                                      19
<PAGE>
 
Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Senior Notes are credited on the record
date (identified in a listing attached to the Omnibus Proxy).
 
  Principal, interest and any premium payments on the Senior Notes will be
made to DTC. DTC's practice is to credit Direct Participant's accounts on
payable date in accordance with their respective holdings shown on DTC's
records unless DTC has reason to believe that it will not receive payment on
payable date. Payments by Participants to Beneficial Owners will be governed
by standing instructions and customary practices, as in the case with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such Participant and not of
DTC, the applicable Trustee or the Company, subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
principal, interest and any premium to DTC is the responsibility of the
Company or the applicable Trustee, disbursement of such payments to Direct
Participants shall be the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners shall be the responsibility of Direct and
Indirect Participants.
 
  DTC may discontinue providing its services as securities depository with
respect to a series of Senior Notes at any time by giving reasonable notice to
the Company or the applicable Trustee. Under such circumstances, if a
successor securities depository is not obtained, certificates for such series
of Senior Notes are required to be printed and delivered.
 
  The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository) for any series of
Senior Notes. In that event, certificates for such series of Senior Notes will
be printed and delivered.

  The information in this section concerning DTC and DTC's book-entry system
has been obtained from DTC, and the Company and any underwriters, dealers or
agents take no responsibility for the accuracy thereof.
 
  The underwriters, dealers or agents of any Senior Notes may be Direct
Participants of DTC.
 
  NONE OF THE COMPANY, THE SENIOR NOTE TRUSTEE, THE ELECTRIC UTILITY MORTGAGE
TRUSTEE, THE GAS UTILITY MORTGAGE TRUSTEE OR ANY AGENT FOR PAYMENT ON OR
REGISTRATION OF TRANSFER OR EXCHANGE OF THE GLOBAL NOTE WILL HAVE ANY
RESPONSIBILITY OR LIABILITY FOR ANY ASPECT OF THE RECORDS RELATING TO OR
PAYMENTS MADE ON ACCOUNT OF BENEFICIAL INTERESTS IN SUCH GLOBAL NOTE OR FOR
MAINTAINING, SUPERVISING OR REVIEWING ANY RECORDS RELATING TO SUCH BENEFICIAL
INTERESTS.

                             PLAN OF DISTRIBUTION
 
  The Company may offer the Senior Notes (i) through underwriters or dealers,
(ii) directly to a limited number of purchasers or to a single purchaser or
(iii) through agents. A Prospectus Supplement with respect to each series of
Senior Notes will set forth the terms of the offering and sale of such Senior
Notes, including the proceeds to the Company from such sale, the name or names
of any underwriters, the purchase price of such Senior Notes, any underwriting
discounts and other items constituting underwriter compensation, any initial
public offering price, any discounts or concessions allowed or reallowed or
paid to dealers and any securities exchanges on which such Senior Notes may be
listed. Any initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers may be changed from time to time.
 
  If underwriters are utilized, the Senior Notes being sold to them will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of
sale. The Senior Notes may be offered to the public either through
underwriting syndicates represented by one or more managing underwriters or
directly by one or more underwriters. The underwriter or underwriters with
respect to the Senior Notes being offered will be named in a Prospectus
Supplement relating to such offering and, if an underwriting syndicate is
used, the managing underwriter or underwriters will be set forth on the cover
page of such Prospectus Supplement. Unless otherwise provided in the
Prospectus Supplement, the obligations of the underwriters will be subject to
certain conditions precedent, and the underwriters will be obligated to
purchase all of such Senior Notes if any are purchased.
 
  The Senior Notes may be sold directly by the Company or through agents
designated by the Company from time to time. Any agent involved in the offer
or sale of any Senior Notes in respect of which this Prospectus is delivered
will be named, and any commissions payable by the Company to such agent will
be set forth, in a Prospectus Supplement. Unless otherwise provided in the
Prospectus Supplement, any such agent will be acting on a best efforts basis
for the period of its appointment.
 
  If so indicated in a Prospectus Supplement, the Company will authorize
agents, underwriters or dealers to solicit offers by certain institutions to
purchase the Senior Notes from the Company at the public offering price set
forth in such Prospectus Supplement pursuant to Delayed Delivery Contracts
("Contracts") providing for payment and delivery on the date or dates stated
in such Prospectus Supplement. Each Contract will be for an amount not less
than, and the aggregate principal amount of the Senior Notes sold pursuant to
the Contracts shall be not less nor more than, the respective amounts stated
in such Prospectus Supplement. Institutions with whom the Contracts, when
authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions, and other institutions, but will in all cases be subject to the
approval of the Company. The Contracts will not be subject to any conditions
except (i) the purchase by an institution of the Senior Notes covered by its
Contract shall not at the time of delivery be prohibited under the laws of any
jurisdiction in the United States to which such institution is subject, and
(ii) if the Senior Notes are being sold to underwriters, the Company shall
have sold to such underwriters the total principal amount of the Senior Notes
less the principal amount thereof covered by the Contracts. The underwriters
will not have any responsibility in respect of the validity or performance of
the Contracts.
 
  Any underwriters, dealers or agents participating in the distribution of the
Senior Notes may be deemed to be underwriters, and any discounts or
commissions received by them on the sale or resale of the Senior Notes may be
deemed to be underwriting discounts and commissions under the Securities Act.
Agents and underwriters may be entitled, under agreements entered into with
the Company, to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act, and to
contribution with respect to payments which the agents or underwriters may be
required to make in respect thereof. Agents and underwriters may engage in
transactions with or perform services for the Company in the ordinary course
of business.

Company by Perkins Coie, Seattle, Washington and for any underwriters, dealers
or agents by Skadden, Arps, Slate, Meagher & Flom, LLP, New York, New York,
which shall rely upon the opinion of Perkins Coie with respect to matters
pertaining to the laws of the State of Washington. All matters pertaining to
the laws of the State of Washington will be passed upon by Perkins Coie.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a court to award, or a corporation's
board of directors to grant, indemnification to directors and officers on
terms sufficiently broad to permit indemnification under certain circumstances
for liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Section 6 of the Company's Bylaws (the "Bylaws"), provides
for indemnification of the Company's directors and officers to the maximum
extent permitted by Washington law.
 
  Section 23B.08.320 of the WBCA authorizes a corporation to eliminate or
limit a director's personal liability to the corporation or its shareholders
for monetary damages for conduct as a director, except in certain
circumstances involving acts or omissions, intentional misconduct by a
director or knowing violations of law by a director or distributions illegal
under Washington law, or any transaction from which the director will
personally receive a benefit in money, property or services to which the
director is not legally entitled. Article X of the Company's Restated Articles
of Incorporation, as amended (the "Articles of Incorporation") contains
provisions implementing, to the fullest extent permitted by Washington law,
such limitations on a director's liability to the Company and its
shareholders.
 
  Officers and directors of the Company are covered by insurance (with certain
exceptions and certain limitations) that indemnifies them against losses and
liabilities arising from certain alleged "wrongful acts," including alleged
errors or misstatements, or certain other alleged wrongful acts or omissions
constituting neglect or breach of duty.
 
  The above discussion of the WBCA and the Bylaws and Articles of
Incorporation is not intended to be exhaustive and is qualified in its
entirety by reference to such statute, the Bylaws and the Articles of
Incorporation.

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, unless the information required to be included in
  such post-effective amendment is contained in a periodic report filed by
  the registrant pursuant to section 13 or section 15(d) of the Securities
  Exchange Act of 1934 and incorporated by reference in this registration
  statement.
 
    (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, unless such information required to be included in
  such post-effective amendment is contained in a periodic report filed by
  the registrant pursuant to section 13 or section 15(d) of the Securities
  Exchange Act of 1934 and incorporated herein by reference. 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 and of the estimated
  maximum offering range may be reflected in the form of a prospectus filed
  with the Commissions 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.
 
  (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) That, for the purpose 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 the 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.
 
  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 foregoing provisions described under Item 15 above,
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 Securities Act of 1933 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 of whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

[OTHER AGENTS]
[ADDRESS]


Ladies and Gentlemen:

          Puget Sound Energy, Inc. a Washington corporation (the "Company"),
confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated and [OTHER AGENTS] (each, an "Agent", and collectively, the
"Agents") with respect to the issue and sale by the Company of its Senior Medium
Term Notes, Series A, Due Nine Months or More From Date of Issue (the "Notes").
The Notes are to be issued pursuant to an Indenture, dated as of November __,
1997, as amended or modified from time to time (the "Indenture"), between the
Company and [TRUSTEE], as trustee (the "Trustee").  Prior to the Substitution
Date (as defined in the Indenture), the Notes will be secured by the delivery to
the Trustee of (i) first mortgage bonds issued under the Company's electric
mortgage indenture or (ii) first mortgage bonds issued under the Company's gas
mortgage indenture, as specified in the Prospectus referred to below
(collectively, the "Pledged Bonds").  As of the date hereof, the Company has
authorized the issuance and sale of up to U.S. $500,000,000 aggregate initial
offering price of Notes to or through the Agents pursuant to the terms of this
Agreement.  It is understood, however, that 
<PAGE>
 
the Company may from time to time authorize the issuance of additional Notes and
that such additional Notes may be sold to or through the Agents pursuant to the
terms of this Agreement, all as though the issuance of such Notes were
authorized as of the date hereof.

          This Agreement provides both for the sale of Notes by the Company to
one or more Agents as principal for resale to investors and other purchasers and
for the sale of Notes by the Company directly to investors (as may from time to
time be agreed to by the Company and the  applicable Agent), in which case the
applicable Agent will act as an agent of the Company in soliciting offers for
the purchase of Notes.

          The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-________)  for the
registration of the Notes, under the Securities Act of 1933, as amended (the
"1933 Act"), and the offering thereof from time to time in accordance with Rule
415 of the rules and regulations of the Commission under the 1933 Act (the "1933
Act Regulations"), and the Company has filed such post-effective amendments
thereto as may be required prior to any acceptance by the Company of an offer
for the purchase of Notes.  Such registration statement (as so amended, if
applicable) has been declared effective by the Commission and the Indenture has
been duly qualified under the Trust Indenture Act of 1939, as amended (the "1939
Act").  Such registration statement (as so amended, if applicable) is referred
to herein as the "Registration Statement"; and the final prospectus and all
applicable amendments or supplements thereto (including the final prospectus
supplement and pricing supplement relating to the offering of Notes), in the
form first furnished to the applicable Agent(s), are collectively referred to
herein as the "Prospectus"; provided, however, that all references to the
"Registration Statement" and the "Prospectus" shall also be deemed to include
all documents incorporated therein by reference pursuant to the Securities
Exchange Act of 1934, as amended (the "1934 Act"), prior to any acceptance by
the Company of an offer for the purchase of Notes; provided, further, that if
the Company files a registration statement with the Commission pursuant to Rule
462(b) of the 1933 Act Regulations (the "Rule 462(b) 

                                       2
<PAGE>
 
Registration Statement"), then, after such filing, all references to the
"Registration Statement" shall also be deemed to include the Rule 462(b)
Registration Statement. A "preliminary prospectus" shall be deemed to refer to
any prospectus used before the registration statement became effective and any
prospectus furnished by the Company after the registration statement became
effective and before any acceptance by the Company of an offer for the purchase
of Notes which omitted information to be included upon pricing in a form of
prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act
Regulations. For purposes of this Agreement, all references to the Registration
Statement, Prospectus or preliminary prospectus or to any amendment or
supplement thereto shall be deemed to include any copy filed with the Commission
pursuant to its Electronic Data Gathering, Analysis and Retrieval system
("EDGAR").

          All references in this Agreement to financial statements and schedules
and other information which is "disclosed", "contained," "included" or "stated"
(or other references of like import) in the Registration Statement, Prospectus
or preliminary prospectus shall be deemed to include all such financial
statements and schedules and other information which is incorporated by
reference in the Registration Statement, Prospectus or preliminary prospectus,
as the case may be; and all references in this Agreement to amendments or
supplements to the Registration Statement, Prospectus or preliminary prospectus
shall be deemed to include the filing of any document under the 1934 Act which
is incorporated by reference in the Registration Statement, Prospectus or
preliminary prospectus, as the case may be.


          1.   Appointment as Agent.
               -------------------- 

          (a) Appointment.  Subject to the terms and conditions stated herein
              -----------                                                    
and subject to the reservation by the Company of the right to sell Notes
directly on its own behalf, the Company hereby agrees that Notes will be sold
exclusively to or through the Agents.  The Company agrees that it will not
appoint any other agents to act on its behalf, or to assist it, in the placement
of the Notes.

                                       3
<PAGE>
 
          (b) Sale of Notes.  The Company shall not sell or approve the
              -------------                                            
solicitation of offers for the purchase of Notes in excess of the amount which
shall be authorized by the Company from time to time or in excess of the
aggregate initial offering price of Notes registered pursuant to the
Registration Statement.  The Agents shall have no responsibility for maintaining
records with respect to the aggregate initial offering price of Notes sold, or
of otherwise monitoring the availability of Notes for sale, under the
Registration Statement.

          (c) Purchases as Principal.  The Agents shall not have any obligation
              ----------------------                                           
to purchase Notes from the Company as principal.  However, absent an agreement
between an Agent and the Company that such Agent shall be acting solely as an
agent for the Company, such Agent shall be deemed to be acting as principal in
connection with any offering of Notes by the Company through such Agent.
Accordingly, the Agents, individually or in a syndicate, may agree from time to
time to purchase Notes from the Company as principal for resale to investors and
other purchasers determined by such Agents.  Any purchase of Notes from the
Company by an Agent as principal shall be made in accordance with Section 3(a)
hereof.

          (d) Solicitations as Agent.  If agreed upon between an Agent and the
              ----------------------                                          
Company, such Agent, acting solely as an agent for the Company and not as
principal, will solicit offers for the purchase of Notes.  Such Agent will
communicate to the Company, orally, each offer for the purchase of Notes
solicited by it on an agency basis other than those offers rejected by such
Agent.  Such Agent shall have the right, in its discretion reasonably exercised,
to reject any offer for the purchase of Notes, in whole or in part, and any such
rejection shall not be deemed a breach of its agreement contained herein.  The
Company may accept or reject any offer for the purchase of Notes, in whole or in
part.  Such Agent shall make reasonable efforts to assist the Company in
obtaining performance by each purchaser whose offer for the purchase of Notes
has been solicited by it on an agency basis and accepted by the Company.  Such
Agent shall not have any liability to the Company in the event that any such
purchase is not consummated for any reason.  If the Company shall default on its
obligation 

                                       4
<PAGE>
 
to deliver Notes to a purchaser whose offer has been solicited by such Agent on
an agency basis and accepted by the Company, the Company shall (i) hold such
Agent harmless against any loss, claim or damage arising from or as a result of
such default by the Company and (ii) pay to such Agent any commission to which
it would otherwise be entitled absent such default.

          (e) Reliance.  The Company and the Agents agree that any Notes
              --------                                                  
purchased from the Company by one or more Agents as principal shall be
purchased, and any Notes the placement of which an Agent arranges as an agent of
the Company shall be placed by such Agent, in reliance on the representations,
warranties, covenants and agreements of the Company contained herein and on the
terms and conditions and in the manner provided herein.

          2.   Representations and Warranties.
               ------------------------------ 

          (a) The Company represents and warrants to each Agent as of the date
hereof, as of the date of each acceptance by the Company of an offer for the
purchase of Notes (whether to such Agent as principal or through such Agent as
agent), as of the date of each delivery of Notes (whether to such Agent as
principal or through such Agent as agent) (the date of each such delivery to
such Agent as principal is referred to herein as a "Settlement Date"), and as of

<PAGE>
 
     ownership or leasing of property or the conduct of business, except where
     the failure to so qualify or be in good standing would not result in a
     material adverse change in the condition, financial or otherwise, or in the
     earnings, business affairs or business prospects of the Company and its
     subsidiaries considered as one enterprise (a "Material Adverse Effect").

          (ii) Significant Subsidiaries. The Company has no significant
               ------------------------

     promulgated under the 1933 Act).

          (iii)  Registration Statement and Prospectus.  The Company meets the
                 -------------------------------------

     of the Registration Statement (including any Rule 462(b) Registration
     Statement) has been issued under the 1933 Act and no proceedings for that
     purpose have been instituted or are pending or, to the knowledge of the
     Company, are contemplated by the Commission, and any request on the part of
     the Commission for additional information has been complied with; the
     Indenture has been duly qualified under the 1939 Act; at the respective

     the Company's most recent Annual Report on Form 10-K with the Commission
     (the "Annual Report on Form 10-K")) became effective and at each
     Representation Date, the Registration Statement (including any Rule 462(b)

     the Commission pursuant to EDGAR, except to the extent permitted by
     Regulation S-T; and at the date hereof, at the date of the Prospectus and
     at each Representation Date, neither the Prospectus nor any amendment or
     supplement thereto included or will include an untrue statement of a
     material fact or omitted or will omit to state a material fact 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

          3.   Purchases as Principal; Solicitations as Agent.
               ----------------------------------------------

              ----------------------                                          
Agents, individually or in a syndicate, as principal shall be made in accordance
with terms agreed upon between such Agent or Agents and the Company (which
terms, unless otherwise agreed, shall, to the extent applicable, include those
terms specified in Exhibit A hereto and shall be agreed upon orally, with
written confirmation prepared by such Agent or Agents and mailed to the
Company).  An Agent's commitment to purchase Notes as principal shall be deemed
to have been made on the basis of the representations and warranties of the
Company herein contained and shall be subject to the terms and conditions herein
set forth.  Unless the context otherwise requires, references herein to "this

                                       14
<PAGE>
 
Agreement" shall include the applicable agreement of one or more Agents to
purchase Notes from the Company as principal.  Each purchase of Notes, unless
otherwise agreed, shall be at a discount from the principal amount of each such
Note equivalent to the applicable commission set forth in Schedule A hereto.
The Agents may engage the services of any broker or dealer in connection with
the resale of the Notes purchased by them as principal and may allow all or any
portion of the discount received from the Company in connection with such
purchases to such brokers or dealers.  At the time of each purchase of Notes
from the Company by one or more Agents as principal, such Agent or Agents shall
specify the requirements for the officers' certificate, opinion of counsel and
comfort letter pursuant to Sections 7(b), 7(c) and 7(d) hereof.

     If the Company and two or more Agents enter into an agreement pursuant to
which such Agents agree to purchase Notes from the Company as principal and one
or more of such Agents shall fail at the Settlement Date to purchase the Notes
which it or they are obligated to purchase (the "Defaulted Notes"), then the
nondefaulting Agents shall have the right, within 24 hours thereafter, to make
arrangements for one of them or one or more other Agents or underwriters to
purchase all, but not less than all, of the Defaulted Notes in such amounts as
may be agreed upon and upon the terms herein set forth; provided, however, that
if such arrangements shall not have been completed within such 24-hour period,
then:

          (a)  if the aggregate principal amount of Defaulted Notes does not
     exceed 10% of the aggregate principal amount of Notes to be so purchased by
     all of such Agents on the Settlement Date, the nondefaulting Agents shall
     be obligated, severally and not jointly, to purchase the full amount
     thereof in the proportions that their respective initial underwriting
     obligations bear to the underwriting obligations of all nondefaulting
     Agents; or

          (b)  if the aggregate principal amount of Defaulted Notes exceeds 10%
     of the aggregate principal amount of Notes to be so purchased by 

                                       15
<PAGE>
 
     all of such Agents on the Settlement Date, such agreement shall terminate
     without liability on the part of any nondefaulting Agent.

No action taken pursuant to this paragraph shall relieve any defaulting Agent
from liability in respect of its default.  In the event of any such default
which does not result in a termination of such agreement, either the
nondefaulting Agents or the Company shall have the right to postpone the
Settlement Date for a period not exceeding seven days in order to effect any
required changes in the Registration Statement or the Prospectus or in any other
documents or arrangements.

          (b) Solicitations as Agent.  On the basis of the representations and
              ----------------------                                          
warranties herein contained, but subject to the terms and conditions herein set
forth, when agreed by the Company and an Agent, such Agent, as an agent of the
Company, will use its reasonable efforts to solicit offers for the purchase of
Notes upon the terms set forth in the Prospectus.  The Agents are not authorized
to appoint sub-agents with respect to Notes sold through them as agent.  All
Notes sold through an Agent as agent will be sold at 100% of their principal
amount unless otherwise agreed upon between the Company and such Agent.

          The Company reserves the right, in its sole discretion, to suspend
solicitation of offers for the purchase of Notes through an Agent, as an agent
of the Company, commencing at any time for any period of time or permanently.
As soon as practicable after receipt of instructions from the Company, such
Agent will suspend solicitation of offers for the purchase of Notes from the
Company until such time as the Company has advised such Agent that such
solicitation may be resumed.

          The Company agrees to pay each Agent a commission, in the form of a
discount, equal to the applicable percentage of the principal amount of each
Note sold by the Company as a result of a solicitation made by such Agent, as an
agent of the Company, as set forth in Schedule A hereto.

          (c) Administrative Procedures.  The purchase price, interest rate or
              -------------------------                                       
formula, maturity date and other

terms of the Notes specified in Exhibit A hereto (as applicable) shall be agreed
upon between the Company and the applicable Agent(s) and specified in a pricing
supplement to the Prospectus (each, a "Pricing Supplement") to be prepared by
the Company in connection with each sale of Notes. Except as otherwise specified
in the applicable Pricing Supplement, the Notes will be issued in denominations
of U.S. $1,000 or any larger amount that is an integral multiple of U.S. $1,000.
Administrative procedures with respect to the issuance and sale of the Notes
(the "Procedures") shall be agreed upon from time to time among the Company, the
Agents and the Trustee. The Agents and the Company agree to perform, and the
Company agrees to cause the Trustee to agree to perform, their respective duties
and obligations specifically provided to be performed by them in the Procedures.

purpose or (v) any change in the rating assigned by any nationally recognized
statistical rating organization to the Program or any debt securities (including

implications, its rating of the Program or any such debt securities, or the
withdrawal by any nationally recognized statistical rating organization of its
rating of the Program or any such debt securities. The Company will make every
reasonable effort to prevent the issuance of any stop order and, if any stop
order is issued, to obtain the lifting thereof at the earliest possible moment.

          (b) Filing or Use of Amendments.  The Company will give the Agents
              ---------------------------

the Registration Statement at the time it became effective or to the Prospectus
(other than an amendment or supplement thereto providing solely for the
determination of the variable terms of the Notes or relating solely to the
offering of securities other than the Notes or an amendment or supplement
pursuant to the requirements of the 1934 Act and the 1934 Act Regulations), will

              -----------------------------                                  
and hold harmless each Agent and each person, if any, who controls such Agent

          (i) against any and all loss, liability, claim and damage whatsoever,

     prospectus or the Prospectus (or any amendment or supplement thereto), or
     the omission or alleged omission therefrom of a material fact necessary in

<PAGE>
 
     were made, not misleading;

     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, provided that (subject to Section
     8(d) hereof) any such settlement is effected with the written consent of
     the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by such Agent), reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity does not apply to any loss, liability,
- --------  -------                                                            
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with written information furnished to the Company by the Agents
expressly for use in the Registration Statement (or any amendment thereto) or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); and provided further, that such indemnity with respect to the
Prospectus shall not inure to the benefit of any Agent (or any person
controlling any Agent) from whom the person asserting any such loss, liability,
claim, damage or expense purchased the Notes which are the subject thereof if
such person did not receive a copy of the Prospectus (or the Prospectus as
supplemented), excluding documents incorporated therein by reference, at or
prior to the confirmation of the sale of such Notes to such person in any case
where such delivery is required by the 1933 Act and the untrue statement or
omission of a material fact 

                                       28
<PAGE>
 
contained in the Prospectus was corrected in the Prospectus as supplemented.

          (b) Indemnification of Company, Directors and Officers.  Each Agent
              --------------------------------------------------

Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in Section 8(a) hereof, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written

shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof and in any event shall not relieve
it from any liability which it may have otherwise than on account of this
indemnity agreement.  In the case of parties indemnified pursuant to Section
8(a) hereof, counsel to the indemnified parties shall be selected by the
applicable Agent(s) and, in the case of parties indemnified pursuant to Section
8(b) hereof, counsel to the indemnified shall be selected by the Company.  An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not

indemnified party.  In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)

<PAGE>
 
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.

          No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 8 or 9 hereof (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

          (d) Settlement without Consent if Failure to Reimburse.  If at any
              --------------------------------------------------            
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable in accordance with Section
8(a)(iii) for any settlement of the nature contemplated by Section 8(a)(ii)
effected without its written consent if (i) such settlement is entered into more
than 45 days after receipt by such indemnifying party of the aforesaid request,
(ii) such indemnifying party shall have received notice of the terms of such
settlement at least 30 days prior to such settlement being entered into and
(iii) such indemnifying party shall not have reimbursed such indemnified party
in accordance with such request prior to the date of such settlement.

          9.   Contribution.  If the indemnification provided for in Section 8
               ------------                                                   
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate 

                                       30
<PAGE>
 
amount of such losses, liabilities, claims, damages and expenses incurred by
such indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company, on the one hand, and the
applicable Agent(s), on the other hand, from the offering of the Notes that were
the subject of the claim for indemnification or (ii) if the allocation provided
by clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company, on the one hand, and the
applicable Agent(s), on the other hand, in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

          The relative benefits received by the Company, on the one hand, and
the applicable Agent(s), on the other hand, in connection with the offering of
the Notes that were the subject of the claim for indemnification shall be deemed
to be in the same respective proportions as the total net proceeds from the
offering of such Notes (before deducting expenses) received by the Company and
the total discount or commission received by each applicable Agent, as the case
may be, bears to the aggregate initial offering price of such Notes.

          The relative fault of the Company, on the one hand, and the applicable
Agent(s), on the other hand, shall be determined by reference to, among other
things, whether any untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the applicable Agent(s) and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

          The Company and the Agents agree that it would not be just and
equitable if contribution pursuant to this Section 9 were determined by pro rata
allocation (even if the applicable Agent(s) 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 Section 9.

                                       31
<PAGE>
 
          Notwithstanding the provisions of this Section 9, (i) no Agent shall
be required to contribute any amount in excess of the amount by which the total
discount or commission received by such Agent in connection with the offering of
the Notes that were the subject of the claim for indemnification exceeds the
amount of any damages which such Agent has otherwise been required to pay by
reason of any applicable untrue or alleged untrue statement or omission or
alleged omission and (ii) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  In addition, in connection with an offering of Notes
purchased from the Company by two or more Agents as principal, the respective
obligations of such Agents to contribute pursuant to this Section 9 are several,
and not joint, in proportion to the aggregate principal amount of Notes that
each such Agent has agreed to purchase from the Company.

          For purposes of this Section 9, each person, if any, who controls an
Agent within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934
Act shall have the same rights to contribution as such Agent, and each director
of the Company, each officer of the Company and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as the Company.

          10.  Payment of Expenses.
               ------------------- 

          The Company will pay all expenses incident to the performance of its
obligations under this Agreement, including:

fees and expenses relating to the eligibility and issuance of Notes in book-

          (g) The fees and expenses incurred in connection with any listing of

disbursements of counsel to the Agents in connection with, the review, if any,

incurred with the approval of the Company.

          11.  Representations, Warranties and Agreements to Survive Delivery.
               -------------------------------------------------------------- 

          All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its
subsidiaries submitted pursuant hereto or thereto shall remain operative and in
full force and effect, regardless of any investigation made by or on behalf of
the Agents or any controlling person of an Agent, or by or on behalf of the
Company, and shall survive each delivery of and payment for the Notes.

          12.  Termination.
               ----------- 

          (a) Termination of this Agreement.  This Agreement (excluding any
              -----------------------------                                
agreement by one or more Agents to purchase Notes from the Company as principal)
may be terminated for any reason, at any time by either the Company or an Agent,
as to itself, upon the giving of 30 days' prior written notice of such
termination to the other party hereto.

          (b) Termination of Agreement to Purchase Notes as Principal.  The
              -------------------------------------------------------      
applicable Agent(s) may terminate any agreement by such Agent(s) to purchase
Notes from the Company as principal, immediately upon notice to the Company, at
any time prior to the Settlement Date relating thereto, if (i) there has been,
since the date of such agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
there has occurred any material adverse change in the financial markets in the
United States or any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development or event involving a prospective
change in national or international political, financial or economic conditions,
in each case the effect of which is such as to make it, in the reasonable
judgment of such Agent(s), impracticable to market such Notes or enforce
contracts for the sale of such 

                                       34
<PAGE>
 
Notes, or (iii) trading in any securities of the Company has been suspended or
limited by the Commission or a national securities exchange, or if trading
generally on the New York Stock Exchange or the American Stock Exchange or in
the NASDAQ National Market has been suspended or limited, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices have been
required, by either of said exchanges or by such system or by order of the
Commission, the NASD or any other governmental authority, or (iv) a banking
moratorium has been declared by either Federal or New York authorities, or (v)
the rating assigned by any nationally recognized statistical rating organization
to the Program or any debt securities (including the Notes) of the Company as of
the date of such agreement shall have been lowered or withdrawn since that date
or if any such rating organization shall have publicly announced that it has
under surveillance or review its rating of the Program or any such debt
securities, or (vi) there shall have come to the attention of such Agent(s) any
facts that would cause such Agent(s) to believe that the Prospectus, at the time
it was required to be delivered to a purchaser of such Notes, included an untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances existing
at the time of such delivery, not misleading.

          (c) General.  In the event of any such termination, neither party will
              -------                                                           
have any liability to the other party hereto, except that (i) the Agents shall
be entitled to any commissions earned in accordance with the third paragraph of
Section 3(b) hereof, (ii) if at the time of termination (a) any Agent shall own
any Notes purchased by it from the Company as principal or (b) an offer to
purchase any of the Notes has been accepted by the Company but the time of
delivery to the purchaser or his agent of such Notes relating thereto has not
occurred, the covenants set forth in Sections 4 and 7 hereof shall remain in
effect until such Notes are so resold or delivered, as the case may be, and
(iii) the covenant set forth in Section 4(i) hereof, the provisions of Section
10 hereof, the indemnity and contribution agreements set forth in Sections 8 and
9 hereof, and the provisions of Sections 11, 14 and 15 hereof shall remain in
effect.

stated maturity and having the same terms and Original Issue Date or Dates.

     (c) All Notes presented for registration of transfer or for exchange,
redemption or payment shall be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the

                                     -18-
<PAGE>
 
Trustee and duly executed by the Holder or the attorney in fact of such Holder
duly authorized in writing.

     (d) No service charge shall be made for any exchange or registration of
transfer of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.

     (e) The Trustee shall not be required to exchange or register a transfer of
any Notes selected, called or being called for redemption (including Notes, if
any, redeemable at the option of the Holder, provided such Notes are then
redeemable at such Holder's option), except, in the case of any Note to be
redeemed in part, the portion thereof not to be so redeemed.

     (f) If the principal amount, and applicable premium, if any, of part, but
not all, of a Global Note is paid, then upon surrender to the Trustee of such
Global Note, the Company shall execute, and the Trustee shall authenticate,
deliver and register, a Global Note in an authorized denomination in aggregate
principal amount equal to, and having the same terms, Original Issue Date or
Dates and series as, the unpaid portion of such Global Note.

SECTION 2.07   MUTILATED, DESTROYED, LOST OR STOLEN NOTES

     (a) If any temporary or definitive Note shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its request the
Trustee shall authenticate and deliver, a new Note of like form and principal
amount and having the same terms and Original Issue Date or Dates and bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen.  In every case the applicant for a substituted Note shall
furnish to the Company, the Trustee and any paying agent or Authenticating Agent
such security or indemnity as may be required by them to save each of them
harmless, and, in every case of destruction, loss or theft of a Note, the
applicant shall also furnish to the Company and to the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.

     (b) The Trustee shall authenticate any such substituted Note and deliver
the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substituted Note, 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 connected therewith.
If any Note which has matured, is about to mature, has been redeemed or called
for redemption shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a

                                     -19-
<PAGE>
 
substituted Note, pay or authorize the payment of the same (without surrender
thereof except in the case of a mutilated Note) if the applicant for such
payment shall furnish to the Company, the Trustee and any paying agent or
Authenticating Agent such security or indemnity as may be required by them to
save each of them harmless and, in case of destruction, loss or theft, evidence
satisfactory to the Company and the Trustee of the destruction, loss or theft of
such Note and of the ownership thereof.

     (c) Every substituted Note issued pursuant to this Section 2.07 by virtue
of the fact that any Note is mutilated, destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
such destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Notes duly issued hereunder.  All Notes shall be held and
owned upon the express condition that, to the extent permitted by law, the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Notes and shall preclude any and all other
rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

SECTION 2.08   TEMPORARY NOTES

     Pending the preparation of definitive Notes, the Company may execute and
the Trustee shall authenticate and deliver temporary Notes (printed,
lithographed or otherwise reproduced).  Temporary Notes shall be issuable in any
authorized denomination and substantially in the form of the definitive Notes
but with such omissions, insertions and variations as may be appropriate for
temporary Notes, all as may be determined by the Company.  Every such temporary
Note shall be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with the same effect, as the definitive
Notes.  Without unreasonable delay the Company shall execute and shall deliver
to the Trustee definitive Notes and thereupon any or all temporary Notes shall
be surrendered in exchange therefor at the corporate trust office of the
Trustee, and the Trustee shall authenticate, deliver and register in exchange
for such temporary Notes an equal aggregate principal amount of definitive
Notes.  Such exchange shall be made by the Company at its own expense and
without any charge therefor to the Noteholders.  Until so exchanged, the
temporary Notes shall in all respects be entitled to the same benefits under
this Indenture as definitive Notes authenticated and delivered hereunder.

SECTION 2.09   CANCELLATION OF NOTES PAID, ETC.

     All Notes surrendered for the purpose of payment, redemption, exchange or
registration of transfer shall be surrendered to the Trustee for cancellation
and

                                     -20-
<PAGE>
 
promptly canceled by it and no Notes shall be issued in lieu thereof except as
expressly permitted by this Indenture.  The Company's acquisition of any Notes
shall operate as a redemption or satisfaction of the indebtedness represented by
such Notes and such Notes shall be surrendered by the Company to and canceled by
the Trustee.

SECTION 2.10   INTEREST RIGHTS PRESERVED

     Each Note delivered under this Indenture upon transfer of or in exchange
for or in lieu of any other Note shall carry all the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Note, and each such
Note shall be so dated that neither gain nor loss of interest shall result from
such transfer, exchange or substitution.

SECTION 2.11   SPECIAL RECORD DATE

     If and to the extent that the Company fails to make timely payment or
provision for timely payment of interest on any issue of Notes (other than on an
Interest Payment Date that is a maturity date), that interest shall cease to be
payable to the Persons who were the Noteholders of such issue at the applicable
Regular Record Date.  In that event, when moneys become available for payment of
that interest, the Trustee shall (a) establish a date of payment of such
interest and a Special Record Date for the payment of that interest, which
Special Record Date shall be not more than 15 or fewer than 10 days prior to the
date of the proposed payment and (b) mail notice of the date of payment and of
the Special Record Date not fewer than 10 days preceding the Special Record Date
to each Noteholder of such issue at the close of business on the 15th day
preceding the mailing at the address of such Noteholder, as it appears on the
register for the Notes.  On the day so established by the Trustee the interest
shall be payable to the Holders of the applicable Notes at the close of business
on the Special Record Date.

SECTION 2.12   PAYMENT OF NOTES

     Payment of the principal, interest and premium on all Notes shall be
payable as follows:

     (a) On or before 11:00 a.m., New York City time, of the day on which
payment of principal, interest and premium, if any, is due on any Global Note
pursuant to the terms thereof, the Company shall deliver to the Trustee funds
available on such date sufficient to make such payment, by wire transfer of
immediately available funds or by instructing the Trustee to withdraw sufficient
funds from an account maintained by the Company with the Trustee or such other
method as is acceptable to the Trustee and, if applicable, the Depositary.  On
or before 2:00 p.m.,

                                     -21-
<PAGE>
 
New York City time, or such other time as shall be agreed upon between the
Trustee and, if applicable, the Depositary, of the day on which any payment of
interest is due on any Global Note (other than at maturity), the Trustee shall
pay to the Depositary such interest in same day funds.  On or before 2:00 p.m.,
New York City time or such other time as shall be agreed upon between the
Trustee and the Depositary, of the day on which principal, interest payable at
maturity and premium, if any, is due on any Global Note, the Trustee shall
deposit with the Depositary the amount equal to the principal, interest payable
at maturity and premium, if any, by wire transfer into the account specified by
the Depositary.

     (b) With respect to any Note that is not a Global Note, principal,
applicable premium and interest due at the maturity of the Note shall be payable
in immediately available funds when due upon presentation and surrender of such
Note at the corporate trust office of the Trustee or at the authorized office of
any paying agent.  Interest on any Note that is not a Global Note (other than
interest payable at maturity) shall be paid to the Holder thereof as its name
appears on the register by check or wire transfer payable in clearinghouse
funds; provided that if the Trustee receives a written request from any Holder
of Notes, the aggregate principal amount of which having the same Interest
Payment Date equals or exceeds $10,000,000, on or before the applicable Regular
Record Date for such Interest Payment Date, interest shall be paid by wire
transfer of immediately available funds to a bank designated by such Holder in
its request or by direct deposit into the account of such Holder designated by
such Holder in its request if such account is maintained with the Trustee or any
paying agent.

     (c) The Trustee shall receive the Pledged First Mortgage Bonds or Pledged
Substituted Mortgage Bonds from the Company as provided in this Indenture and
shall hold the Pledged First Mortgage Bonds or Pledged Substituted Mortgage
Bonds, and any and all sums payable thereon or with respect thereto or realized
therefrom, in trust for the benefit of the Holders of the Notes, as herein
provided.  Subject to Article Eight hereof, the Company's obligations to make
payments with respect to the principal of, premium or interest on Pledged First
Mortgage Bonds or Pledged Substituted Mortgage Bonds will be fully or partially,
as the case may be, satisfied and discharged to the extent that, at the time
that any such payment shall be due, the then due principal of, premium or
interest on the related issue of Notes shall have been fully or partially paid
or there shall have been deposited with the Trustee pursuant to this Section
2.12 sufficient available funds to fully or partially pay the then due principal
of, premium, if any, or interest on such related issue of Notes.

SECTION 2.13  NOTES ISSUABLE IN THE FORM OF A GLOBAL NOTE

     (a) If the Company shall establish pursuant to Section 2.05 hereof that the
Notes of a particular series are to be issued in whole or in part in the form of
one or more Global Notes, then the Company shall execute and the Trustee shall,
in accordance with Section 2.05 hereof and the Company Order delivered to the
Trustee thereunder, authenticate and deliver such Global Note or Notes, which
(i) shall represent, shall be denominated in an amount equal to the aggregate
principal amount of, and shall have the same terms as, the outstanding Notes to
be represented by such Global Note or Notes, (ii) shall be registered in the
name of the Depositary or its nominee, (iii) shall be delivered by the Trustee
to the Depositary or pursuant to the Depositary's instruction and (iv) shall
bear a legend substantially to the following effect: "This Note is a Global Note
registered in the name of the Depositary (referred to herein) or a nominee
thereof and, unless and until it is exchanged in whole or in part for the
individual Notes represented hereby, this Global Note may not be transferred
except as a whole by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary
or by the Depositary or any such nominee to a successor Depositary or a nominee
of such successor Depositary.  Unless this Global Note is presented by an
authorized representative of The Depositary Trust Company, to the trustee for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or such other name as requested by an
authorized representative of The Depositary Trust Company and any payment is
made to Cede & Co., any transfer, pledge or other use hereof for value or
otherwise by or to any person is wrongful since the registered owner hereof,
Cede & Co., has an interest herein" or such other legend as may be required by
the rules and regulations of the Depositary.

     (b) Notwithstanding any other provision of Section 2.06 hereof or of this
Section 2.13, unless the terms of a Global Note expressly permit such Global
Note to be exchanged in whole or in part for individual Notes, a Global Note may
be transferred, in whole but not in part, only as described in the legend
thereto.

     (c)  (i)  If at any time the Depositary for a Global Note notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Note or if at any time the Depositary for the Global Note shall no longer be
eligible or in good standing under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or other applicable statute or regulation, the
Company shall appoint a successor Depositary, with respect to such Global Note.
If a successor Depositary for such Global Note is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election pursuant to Section 2.05(c)(vii) hereof
shall no longer be effective with respect to the

                                     -23-
<PAGE>
 
series of Notes evidenced by such Global Note and the Company shall execute, and
the Trustee, upon receipt of a Company Order for the authentication and delivery
of individual Notes of such series in exchange for such Global Note, shall
authenticate and deliver, individual Notes of such series of like tenor and
terms in definitive form in an aggregate principal amount equal to the amount of
the Global Note in exchange for such Global Note.  The Trustee shall not be
charged with knowledge or notice of the ineligibility of a Depositary unless a
responsible officer assigned to and working in its corporate trustee
administration department shall have actual knowledge thereof.

     (ii)   The Company may at any time and in its sole discretion determine
that all (but not less than all) outstanding Notes of a series issued or
issuable in the form of one or more Global Notes shall no longer be represented
by such Global Note or Notes. In such event the Company shall execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Notes in exchange for such Global Note, shall authenticate and
deliver individual Notes of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such Global Note or
Notes in exchange for such Global Note or Notes.

     (iii)  In any exchange provided for in any of the preceding two paragraphs,
the Company will execute and the Trustee will authenticate and deliver
individual Notes in definitive registered form in authorized denominations.
Upon the exchange of a Global Note for individual Notes, such Global Note shall
be canceled by the Trustee.  Notes issued in exchange for a Global Note pursuant
to this Section shall be registered in such names and in such authorized
denominations as the Depositary for such Global Note, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Notes to the Depositary for delivery to
the persons in whose names such Notes are so registered, or if the Depositary
shall refuse or be unable to deliver such Notes, the Trustee shall deliver such
Notes to the persons in whose names such Notes are registered, unless otherwise
agreed upon between the Trustee and the Company, in which event the Company
shall cause the Notes to be delivered to the persons in whose names such Notes
are registered.

     (d)    Neither the Company, the Trustee, any Authenticating Agent nor any
paying agent shall have any responsibility or liability for any aspect of the
records relating to, or payments made on account of beneficial ownership
interests of a Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

     (e)    Pursuant to the provisions of this subsection, at the option of the
Trustee and upon 30 days' written notice to the Depositary but not prior to the
first Interest Payment Date of the respective Global Notes, the Depositary shall
be required to

                                     -24-
<PAGE>
 
surrender any two or more Global Notes which have identical terms, including,
without limitation, identical maturities, interest rates and redemption
provisions (but which may have differing Original Issue Dates) to the Trustee,
and the Company shall execute, and the Trustee shall authenticate and deliver
to, or at the direction of, the Depositary, a Global Note in principal amount
equal to the aggregate principal amount of, and with all terms identical to, the
Global Notes surrendered thereto and that shall indicate each applicable
Original Issue Date and the principal amount applicable to each such Original
Issue Date.  The exchange contemplated in this subsection shall be consummated
at least 30 days prior to any Interest Payment Date applicable to any of the
Global Notes surrendered to the Trustee.  Upon any exchange of any Global Note
with two or more Original Issue Dates, whether pursuant to this Section or
pursuant to Section 2.06 or Section 3.03 hereof, the aggregate principal amount
of the Notes with a particular Original Issue Date shall be the same before and
after such exchange, after giving effect to any retirement of Notes and the
Original Issue Dates applicable to such Notes occurring in connection with such
exchange.

                                 ARTICLE THREE

                              REDEMPTION OF NOTES

SECTION 3.01  APPLICABILITY OF ARTICLE

     Such of the Notes as are, by their terms, redeemable prior to their stated
maturity date at the option of the Company, may be redeemed by the Company at
such times, in such amounts and at such prices as may be specified therein and
in accordance with the provisions of this Article Three.

SECTION 3.02  NOTICE OF REDEMPTION; SELECTION OF NOTES

     (a) The election of the Company to redeem any Notes shall be evidenced by a
Board Resolution or a Company Order which shall be given with notice of
redemption to the Trustee at least 45 days (or such shorter period acceptable to
the Trustee in its sole discretion) prior to the redemption date specified in
such notice.

     (b) Following receipt of the Company's notice pursuant to Section 3.02(a)
hereof, notice of redemption to each Holder of Notes to be redeemed as a whole
or in part shall be given by the Trustee, at the expense of the Company, in the
manner provided in Section 15.10 hereof, no less than 30 or more than 60 days
prior to the date fixed for redemption.  Any notice which is given in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the Noteholder receives the notice.  In any case, failure duly to give
such notice, or any defect in such notice, to the Holder of any Note designated
for redemption as a whole

                                     -25-
<PAGE>
 
or in part shall not affect the validity of the proceedings for the redemption
of any Note.

     (c) Each such notice shall specify the date fixed for redemption, the
places of redemption and the redemption price at which such Notes are to be
redeemed, and shall state that payment of the redemption price of such Notes or
portion thereof to be redeemed will be made upon surrender of such Notes at such
places of redemption, that interest accrued to the date fixed for redemption
will be paid as specified in such notice, and that from and after such date
interest thereon shall cease to accrue.  If less than all of a series of Notes
having the same terms are to be redeemed, the notice shall specify the Notes or
portions thereof to be redeemed.  If any Note is to be redeemed in part only,
the notice which relates to such Note shall state the portion of the principal
amount thereof to be redeemed, and shall state that, upon surrender of such
Note, a new Note or Notes having the same terms in aggregate principal amount
equal to the unredeemed portion thereof will be issued.

     (d) Unless otherwise provided by a supplemental indenture or Company Order
under Section 2.05 hereof, if less than all of a series of Notes having the same
terms are to be redeemed, the Trustee shall select pro rata or by lot, or in
such other manner as it shall deem appropriate and fair in its discretion the
particular Notes to be redeemed in whole or in part and shall thereafter
promptly notify the Company in writing of the Notes so to be redeemed.  If less
than all of a series of Notes represented by a Global Note are to be redeemed,
the particular Notes or portions thereof of such series to be redeemed shall be
selected by the Depositary for such series of Notes in such manner as the
Depositary shall determine.  Notes shall be redeemed only in denominations of
$1,000, provided that any remaining principal amount of a Note redeemed in part
shall be a denomination authorized under this Indenture.

     (e) If at the time of the mailing of any notice of redemption the Company
shall not have irrevocably directed the Trustee to apply funds deposited with
the Trustee or held by it and available to be used for the redemption of Notes
to redeem all the Notes called for redemption, such notice, at the election of
the Company, may state that it is subject to the receipt of the redemption
moneys by the Trustee before the date fixed for redemption and that such notice
shall be of no effect unless such moneys are so received before such date.

SECTION 3.03  PAYMENT OF NOTES ON REDEMPTION; DEPOSIT OF REDEMPTION PRICE

     (a) If notice of redemption for any Notes shall have been given as provided
in Section 3.02 hereof and such notice shall not contain the language permitted
at the

                                     -26-
<PAGE>
 
Company's option under Section 3.02(e) hereof, such Notes or portions of Notes
called for redemption shall become due and payable on the date and at the places
stated in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption of such Notes.  Interest on the Notes
or portions thereof so called for redemption shall cease to accrue and such
Notes or portions thereof shall be deemed not to be entitled to any benefit
under this Indenture except to receive payment of the redemption price together
with interest accrued thereon to the date fixed for redemption.  Upon
presentation and surrender of such Notes at such a place of payment in such
notice specified, such Notes or the specified portions thereof shall be paid and
redeemed at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption.

     (b) If notice of redemption shall have been given as provided in Section
3.02 hereof and such notice shall contain the language permitted at the
Company's option under Section 3.02(e) hereof, such Notes or portions of Notes
called for redemption shall become due and payable on the date and at the places
stated in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption of such Notes, and interest on the
Notes or portions thereof so called for redemption shall cease to accrue and
such Notes or portions thereof shall be deemed not to be entitled to any benefit
under this Indenture except to receive payment of the redemption price together
with interest accrued thereon to the date fixed for redemption; provided that,
in each case, the Company shall have deposited with the Trustee or a paying
agent on or prior to such redemption date an amount sufficient to pay the
redemption price together with interest accrued to the date fixed for
redemption.  Upon the Company making such deposit and upon presentation and
surrender of such Notes at the place of payment in such notice specified, such
Notes or the specified portions thereof shall be paid and redeemed at the
applicable redemption price, together with interest accrued thereon to the date
fixed for redemption.  If the Company shall not make such deposit on or prior to
the redemption date, the notice of redemption shall be of no force and effect
and the principal on such Notes or specified portions thereof shall continue to
bear interest as if the notice of redemption had not been given.

     (c) No notice of redemption of Notes shall be mailed during the continuance
of any Event of Default, except (1) that, when notice of redemption of any Notes
has been mailed, the Company shall redeem such Notes but only if funds
sufficient for that purpose have prior to the occurrence of such Event of
Default been deposited with the Trustee or a paying agent for such purpose, and
(2) that notices of redemption of all outstanding Notes may be given during the
continuance of an Event of Default.

                                     -27-
<PAGE>
 
     (d) Upon surrender of any Note redeemed in part only, the Company shall
execute, and the Trustee shall authenticate, deliver and register, a new Note or
Notes of authorized denominations in aggregate principal amount equal to, and
having the same terms, Original Issue Date or Dates and series as, the
unredeemed portion of the Note so surrendered.

principal amount of Debt (plus any premium or fee payable in connection with
such extension, renewal or replacement) so secured at the time of such
extension, renewal or replacement; and 

                                     -39-

political subdivision of any of the foregoing, to secure partial, progress,
advance or other payments pursuant to the provisions of any contract or statute,
or any Mortgage securing industrial development, pollution control or similar
revenue bonds shall not be deemed to create a Mortgage to secure any Debt.

     (c)  On and after the Substitution Date, if and only if no Pledged
Substituted Mortgage Bonds have been delivered to the Trustee, the Company will
not sell or transfer any Principal Property, with the Company taking back a
lease of such Principal Property (a "Sale-Leaseback Transaction"), unless (i)
such Sale-Leaseback Transaction occurs within 180 days from the date of
acquisition of such Principal Property or the date of the completion of
construction or commencement of full operations on such Principal Property,
whichever is later, or (ii) the Company, within 120 days after such Sale-
Leaseback Transaction, applies or causes to be applied to the retirement of Debt
of the Company (other than Debt of the Company which by its terms or the terms
of the instrument pursuant to which it was issued is subordinate in right of
payment to the Notes) an amount not less than the net proceeds of the sale of
such Principal Property.

     Notwithstanding the foregoing provisions of this Section 6.07(c), the
Company may effect any Sale-Leaseback Transaction involving any Principal
Property, provided that the net sale proceeds from such Sale-Leaseback
Transaction, together with all other Sale-Leaseback Transactions which are not
permitted pursuant to clauses (i) or (ii) of the foregoing paragraph and all
Debt secured by Mortgages not specifically excluded pursuant to any of clauses
(i) through (vi) of Section 6.07(b) from the operation of Section 6.07(b), does

days prior to the time such information is furnished or caused to be furnished
and need not include information received after such date; provided that as long
as the Trustee is the registrar for the Notes, no such list shall be required to
be furnished.  The Trustee shall preserve any list provided to it pursuant to
this Section until such time as the Company or any paying agent, as applicable,
shall provide it with a more recent list.

     (b) Within five Business Days after the receipt by the Trustee of a written
application by any three or more Holders stating that the applicants desire to
communicate with other Holders with respect to their rights under the Indenture
or under the Notes, and accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, and by reasonable proof
that each such applicant has owned a Note for a period of at least six months
preceding the date of such application, the Trustee shall, at its election,
either:

     (i)  afford to such applicants access to all information furnished to or
received by the Trustee pursuant to Section 7.01(a) hereof or, if applicable, in
its capacity as registrar for the Notes; or

     (ii) inform such applicants as to the approximate number of Holders
according to the most recent information furnished to or received by the Trustee
under Section 7.01(a) hereof or if applicable in its capacity as registrar for
the Notes, and as

                                     -41-
<PAGE>
 
to the approximate cost of mailing to such Holders the form of proxy or other
communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of Notes a copy of the form of proxy or other communication
which is specified in such request, with reasonable promptness after a tender to
the Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of such mailing, unless within five days
after such tender the Trustee shall mail to such applicants and file with the
SEC, together with a copy of the material to be mailed, a written statement to
the effect that, in the opinion of the Trustee, such mailing would be contrary
to the best interests of the Holders or would be in violation of applicable law.
Such written statement shall specify the basis of such opinion.  If the SEC,
after opportunity for a hearing upon the objections specified in the written
statement so filed, shall enter an order refusing to sustain any of such
objections or after the entry of an order sustaining one or more of such
objections, the SEC shall find, after notice and opportunity for hearing, that
all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all Holders with
reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

     (c) Every Holder of a Note, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any
paying agent nor any Authenticating Agent shall be held accountable by reason of
the disclosure of any such information as to the names and addresses of the
Holders in accordance with this Section, regardless of the source from which
such information was derived, and that the Trustee shall not be held accountable
by reason of mailing any material pursuant to a request made under this Section.

     The Company shall:

     (a) file with the Trustee, within 15 days after the Company is required to

as the SEC may from time to time by rules and regulations prescribe) which the
Company may be required to file with the SEC pursuant to Section 13 or Section
15(d) of the Exchange Act; or, if the Company is not required to file

if required by such rules and regulations, certificates or opinions of
independent public accountants, conforming to the requirements of Section 15.05
hereof, as to compliance with conditions or covenants, compliance with which is
subject to verification by accountants; and

     (c) transmit by mail to all Holders, as their names and addresses appear in
the register, within 30 days after the filing thereof with the Trustee, such
summaries of any information, documents and reports required to be filed by the

TIA (to the extent required by such Section).

                       NOTEHOLDERS ON EVENTS OF DEFAULT

SECTION 8.01  EVENTS OF DEFAULT

     (a) If one or more of the following Events of Default shall have occurred
and be continuing:

     (1) default in the payment of any installment of interest upon any of the
Notes as and when the same shall become due and payable, and continuance of such
default for a period of 30 days;

     (2) default in the payment of the principal of or premium, if any, on any
of the Notes as and when the same shall become due and payable and continuance
of such default for five days;

     (3) failure on the part of the Company duly to observe or perform any other
of the covenants or agreements on the part of the Company contained in the Notes
or in this Indenture for a period of 90 days after the date on which written
notice of such failure, requiring the same to be remedied and stating that such
notice is a "Notice of Default" hereunder, shall have been given to the Company
by the Trustee by registered mail, or to the Company and the Trustee by the
Holders of at least a majority in aggregate principal amount of the Notes at the
time outstanding;

     (4) prior to the Substitution Date, a default (as defined in either of the
First Mortgages under which Pledged First Mortgage Bonds are outstanding) has
occurred and is continuing, and the applicable Mortgage Trustee or Holders of at
least a majority in aggregate principal amount of the Notes at the time
outstanding shall have given written notice thereof to the Trustee;

                                     -44-
<PAGE>
 
     (5) if any Pledged Substituted Mortgage Bonds are outstanding, a default
(as defined in the Substituted Mortgage) has occurred and is continuing, and the
Mortgage Trustee or Holders of at least a majority in aggregate principal amount
of the Notes at the time outstanding shall have given written notice thereof to
the Trustee;

     (6) the entry of a decree or order by a court having jurisdiction over the
Company for relief in respect of the Company under the United States Bankruptcy
Code, 11 U.S.C. (S)(S) 101-1330, as now constituted or hereafter amended (the
"Bankruptcy Code"), or any other applicable federal or state bankruptcy,
insolvency or other similar law, or appointing a receiver, liquidator, assignee,
trustee, custodian, sequestrator or 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 unstayed and in
effect for a period of 60 consecutive days; or

     (7) the filing by the Company with respect to itself or its property of a
petition or answer or consent seeking relief under the Bankruptcy Code, or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or the consent by it to the institution of proceedings thereunder or to the
filing of any such petition or to the appointment of or taking possession by a
receiver, liquidator, assignee, trustee, custodian, sequestrator or other
similar official of the Company or of any substantial part of its property, or
the failure of the Company generally to pay its debts as such debts become due,
or the taking of corporate action by the Company to effectuate any such action;

then and in each and every such case, unless the principal of all of the Notes
shall have already become due and payable, either the Trustee or the Holders of
a majority in aggregate principal amount of the Notes then outstanding, by
notice in writing to the Company (and to the Trustee if given by Noteholders),
may declare the principal of all the Notes to be due and payable immediately and
upon any such declaration the same shall become and shall be immediately due and
payable, anything in this Indenture or in the Notes contained to the contrary
notwithstanding and, upon the Notes being declared to be due and payable, the
Trustee shall immediately file with the Mortgage Trustee a written demand for
redemption of all Pledged First Mortgage Bonds pursuant to the applicable
provisions of the First Mortgage or, if applicable, a written demand for
redemption of all Pledged Substituted Mortgage Bonds pursuant to the applicable
provisions of the Substituted Mortgage.  This provision, however, is subject to
the condition that if, at any time after the principal of the Notes shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided and

                                     -45-
<PAGE>
 
prior to the mailing to the Trustee by the Mortgage Trustee of a firm, valid and
unconditional notice to the Trustee of the acceleration of all of the first
mortgage bonds issued and outstanding under the First Mortgage or the
Substituted Mortgage, the Company shall pay or shall deposit with the Trustee a
sum sufficient to pay all matured installments of interest upon all of the Notes
and the principal of and any premium on any and all Notes which shall have
become due otherwise than by acceleration (with interest on overdue installments
of interest, to the extent that payment of such interest is enforceable under
applicable law, and on such principal and applicable premium at the rate borne
by the Notes to the date of such payment or deposit) and all sums paid or
advanced by the Trustee hereunder, the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.06 hereof and any and all defaults under
this Indenture, other than the non-payment of principal of and accrued interest
on Notes which shall have become due solely by acceleration of maturity, shall
have been cured or waived (including any defaults under the First Mortgage, as
evidenced by notice thereof from the Mortgage Trustee to the Trustee), then and
in every such case such payment or deposit shall cause an automatic waiver of
the Event of Default and its consequences (including, if given, the written
demand for redemption of all Pledged First Mortgage Bonds or, if applicable, all
Pledged Substituted Mortgage Bonds) and shall cause an automatic rescission and
annulment of the acceleration of the Notes; but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default, or shall
impair any right consequent thereon.

     (b) If the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such rescission or annulment or for any other reason or shall have been
determined adversely to the Trustee, then and in every such case the Company and
the Trustee shall be restored respectively to their several positions and rights
hereunder, and all rights, remedies and powers of the Company and the Trustee
shall continue as though no such proceeding had been taken.

SECTION 8.02  ENFORCEMENT BY TRUSTEE

     (a) If there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor on the Notes under the
Bankruptcy Code or any other applicable law, or in case a receiver or trustee
shall have been appointed for the property of the Company or such other obligor,
or in the case of any similar judicial proceedings relative to the Company or
other obligor on the Notes, or to the creditors or property of the Company or
such other obligor, the Trustee, irrespective of whether the principal of the
Notes shall then be due and

                                     -46-
<PAGE>
 
payable as therein expressed or by declaration or otherwise, shall be entitled
and empowered, by intervention in such proceedings or otherwise, to file and
prove a claim or claims for the whole amount of principal and any premium and
interest owing and unpaid in respect of the Notes, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including,
prior to the Substitution Date, any claims of the Trustee as holder of Pledged
First Mortgage Bonds or, if applicable, on and after the Substitution Date, any
claims of the Trustee as holder of Pledged Substituted Mortgage Bonds, and
including any amounts due to the Trustee under Section 9.06 hereof) and of the
Holders of Notes allowed in such judicial proceedings relative to the Company or
any other obligor on the Notes, its or their creditors, or its or their
property, and to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of its charges and expenses.

     (b)  All claims and rights of action under this Indenture, or under any of
the Notes, may be enforced by the Trustee without the possession of any of the
Notes, or the production thereof in any trial or other proceeding relative
thereto, and any such suit or proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall be for the ratable benefit of the Holders of the Notes in respect
of which such action was taken.

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

SECTION 8.03  APPLICATION OF MONEYS COLLECTED BY TRUSTEE

     Any moneys collected by the Trustee with respect to any of the Notes
pursuant to this Article shall be applied in the order following, at the date or

partially paid, and upon surrender thereof if fully paid.

     FIRST: To the payment of all amounts due to the Trustee pursuant to
Section 9.06 hereof;

     SECOND: If the principal of the outstanding Notes in respect of which such
moneys have been collected shall not have become due and be unpaid, to the

installments of such

                                    -47-  
<PAGE>
 
interest, with interest (to the extent allowed by law and to the extent that
such interest has been collected by the Trustee) upon the overdue installments
of interest at the rate borne by the Notes, such payments to be made ratably to
the persons entitled thereto, and then to the payment to the Holders entitled
thereto of the unpaid principal of and applicable premium on any of the Notes
which shall have become due (other than Notes previously called for redemption
for the payment of which moneys are held pursuant to the provisions of this
Indenture), whether at stated maturity or by redemption, in the order of their
due dates, beginning with the earliest due date, and if the amount available is
not sufficient to pay in full all Notes due on any particular date, then to the
payment thereof ratably, according to the amounts of principal and applicable
premium due on that date, to the Holders entitled thereto, without any
discrimination or privilege;

     THIRD: If the principal of the outstanding Notes in respect of which such
moneys have been collected shall have become due, by declaration or otherwise,
to the payment of the whole amount then owing and unpaid upon the Notes for
principal and premium, if any, and interest thereon, with interest on the
overdue principal and any premium and (to the extent allowed by law and to the
extent that such interest has been collected by the Trustee) upon overdue
installments of interest at the rate borne by the Notes; and in case such moneys
shall be insufficient to pay in full the whole amount so due and unpaid upon the
Notes, then to the payment of such principal and any premium and interest
without preference or priority of principal and any premium over interest, or of
interest over principal and any premium or of any installment of interest over
any other installment of interest, or of any Note over any other Note, ratably
to the aggregate of such principal and premium, if any, and accrued and unpaid
interest; and

     FOURTH: to the payment of the remainder, if any, to the Company or its
successors or assigns, or to whomsoever may lawfully be entitled to the same, or
as a court of competent jurisdiction may determine.

SECTION 8.04  PROCEEDINGS BY NOTEHOLDERS

     (a)  No Holder of any Note shall have any right by virtue of or by availing
of any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
such Holder previously shall have given to the Trustee written notice of an
Event of Default with respect to such Note and of the continuance thereof, as
hereinabove provided, and unless also Noteholders of a majority in aggregate
principal amount of the Notes then outstanding affected by such Event of Default
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and

                                     -48-
<PAGE>
 
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby,
and the Trustee for 60 days after its receipt of such notice, request and offer
of indemnity, shall have neglected or refused to institute any such action, suit
or proceeding.

     (b)  Notwithstanding any other provision in this Indenture, however, the
rights of any Holder of any Note to receive payment of the principal of and any
premium and interest on such Note, on or after the respective due dates
expressed in such Note or on the applicable redemption date, or to institute
suit for the enforcement of any such payment on or after such respective dates
shall not be impaired or affected without the consent of such Holder.

SECTION 8.05  PROCEEDINGS BY TRUSTEE

     In case of an Event of Default hereunder the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture,
including its rights as holder of the Pledged First Mortgage Bonds or the
Pledged Substituted Mortgage Bonds, by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted to it
under this Indenture, or to enforce any other legal or equitable right vested in
the Trustee by this Indenture or by law.

SECTION 8.06  REMEDIES CUMULATIVE AND CONTINUING

     All powers and remedies given by this Article Eight to the Trustee or to
the Noteholders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any powers and remedies hereof or of any other powers and
remedies available to the Trustee or the Holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any Holder of any of the Notes in exercising any right or
power accruing upon any default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such
default or an acquiescence therein; and, subject to Section 8.04 hereof, every
power and remedy given by this Article Eight or by law to the Trustee or to the
Noteholders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

                                     -49-
<PAGE>
 
SECTION 8.07  DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF
              NOTEHOLDERS

     The Holders of a majority in aggregate principal amount of the Notes at the
time outstanding 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; provided, that (subject to Section
9.01 hereof) the Trustee shall have the right to decline to follow any such
direction if the Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith
by its board of directors or trustees, executive committee, or a trust committee
of directors or trustees or responsible officers shall determine that the action
or proceeding so directed would involve the Trustee in personal liability or
would be unduly prejudicial to the rights of Noteholders not joining in such
directions.  The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may on behalf of all of the Holders of the Notes
waive any past default or Event of Default hereunder and its consequences except
a default in the payment of principal of or any premium or interest on the
Notes.  Upon any such waiver the Company, the Trustee and the Holders of the
Notes shall be restored to their former positions and rights hereunder,
respectively, but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon.  Whenever any
default or Event of Default hereunder shall have been waived as permitted by
this Section 8.07, said default or Event of Default shall for all purposes of
the Notes and this Indenture be deemed to have been cured and to be not
continuing.

SECTION 8.08  NOTICE OF DEFAULT

     The Trustee shall within 90 days after the occurrence of a default known to
it, give to all Holders of the Notes, in the manner provided in Section 15.10
hereof, notice of such default, unless such default shall have been cured before
the giving of such notice, the term "default" for the purpose of this Section
8.08 being hereby defined to be any event which is or after notice or lapse of
time or both would become an Event of Default; provided that, except in the case
of default in the payment of the principal of or any premium or interest on any
of the Notes, or in the payment of any sinking or purchase fund installments,
the Trustee shall be protected in withholding such notice if and so long as its
board of directors or trustees, executive committee, or a trust committee of
directors or trustees or responsible officers in good faith determines that the
withholding of such notice is in the interests of the Holders of the Notes.  The
Trustee shall not be charged with knowledge of any Event of Default unless a
responsible officer of the Trustee assigned to the corporate trustee department
of the Trustee shall have actual knowledge of such Event of Default.

                                     -50-
<PAGE>
 
SECTION 8.09  UNDERTAKING TO PAY COSTS

     All parties to this Indenture agree, and each Holder of any Note by
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but this
Section 8.09 shall not apply to any suit instituted by the Trustee, or to any
suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than 10% in principal amount of the Notes outstanding, or to any
suit instituted by any Noteholder for the enforcement of the payment of the
principal of or any premium or interest on any Note on or after the due date
expressed in such Note or the applicable redemption date.

waived), the Trustee shall exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of

or waiving of all Events of Default which may have occurred

     (A)  the duties and obligations of the Trustee shall be determined solely
by the express provisions of this Indenture, and the Trustee shall not be liable

may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee and conforming to the requirements of this Indenture; but, in the
case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall be under
a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture as to form;

omitted to be taken by it in good faith in accordance with Section 8.07 hereof
relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon
the Trustee under this Indenture.

SECTION 9.02  RELIANCE ON DOCUMENTS, OPINIONS, ETC.

     Except as otherwise provided in Section 9.01 hereof:

report, notice, request, consent, order, note or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

<PAGE>
 
     (d)  the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Noteholders, pursuant to this Indenture, unless such Noteholders
shall have offered to the Trustee reasonable security or indemnity against the
costs, expenses and liabilities which may be incurred by such exercise;

     (e)  the Trustee shall not be liable for any action taken, suffered or

agent or registrar.

SECTION 9.05  MONEYS TO BE HELD IN TRUST

     Subject to Section 5.04 hereof all moneys received by the Trustee shall,

for, and to hold it harmless against, any loss, liability or expense incurred
without negligence or bad faith on the part of the Trustee and arising out of or

costs and expenses of defending itself against any claim or liability.  The
obligations of the Company under this Section 9.06 to compensate the Trustee and
to pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder.  Such additional indebtedness
shall be secured by a lien prior to that of the Notes upon all property and
funds held or collected by the Trustee as such, except funds held in trust for
the benefit of the Holders of any particular Notes.

Street Bank and Trust Company shall not be deemed to have a conflicting interest

percentage in aggregate principal amount of the Notes may take any action, the
fact that at the time of taking any such action the Holders of such specified
percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by such Noteholders in person or
by agent or

                                     -59-

proxy appointed in writing, (b) by the record of such Noteholders voting in

satisfactory to the Trustee.  The ownership of Notes shall be proved by the
register for the Notes maintained by the Trustee.

     (b) The record of any Noteholders' meeting shall be proven in the manner
provided in Section 11.06 hereof.

SECTION 10.03  WHO DEEMED ABSOLUTE OWNERS

     Subject to Sections 2.04(f) and 10.01 hereof, the Company, the Trustee, any

principal and premium, if any, and interest on such Note, and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any
Authenticating Agent shall be affected by any notice to the contrary.  All such
payments shall be valid and effectual to satisfy and discharge the liability
upon any such Note to the extent of the sum or sums so paid.

SECTION 10.04  COMPANY-OWNED NOTES DISREGARDED

under this Indenture, Notes which are owned by the Company or any other obligor
on the Notes or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company or any other
obligor on the Notes shall be disregarded and deemed not to be outstanding for
the purpose of any such determination; provided that, for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver, only Notes which the Trustee knows are so owned

satisfaction of the Trustee the pledgee's right to take action with respect to
such Notes and that the pledgee is not a person directly or indirectly

Company or any such other obligor.  In the case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

have consented to such action may, by filing written notice with the Trustee at
the corporate trust office of the Trustee and upon proof of ownership as
provided in Section 10.02(a) hereof, revoke such action so far as it concerns

shall be conclusive and binding upon such Holder and upon all future Holders and
owners of such Note and of any Notes issued in exchange, substitution or upon
registration of transfer therefor, irrespective of whether or not any notation
thereof is made upon such Note or such other Notes.

at its option, by Board Resolution, fix in advance a record date for the
determination of Noteholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other act, but the Company
shall have no obligation to do so.  If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other act
may be given before or after the record date, but only the Noteholders of record
at the close of business on the record date shall be deemed to be Noteholders
for the purpose of determining whether Holders of the requisite aggregate
principal amount of outstanding Notes have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
act, and for that purpose the outstanding Notes shall be computed as of the
record date; provided that no such request, demand, authorization, direction,
notice, consent, waiver or other act by the Noteholders on the record date shall

supplemental indenture pursuant to this Section 13.02, the Trustee shall give
notice in the manner provided in Section 15.10 hereof, setting forth in general

failure of the Trustee to give such notice or any defect therein shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

proposed supplemental indenture would affect only a limited number of series or
issues of Notes, only the Holders of the Notes so affected shall be entitled to
consent to such supplemental indenture, and, subject to Sections 13.02(a)(1) and

Harris Trust and Savings Bank, Chicago, Illinois, as trustee (the "Gas Mortgage
Trustee" and, together with the Electric Mortgage Trustee, the "Mortgage
Trustee"), as supplemented and amended (the "Gas Mortgage" and, together with
the Electric Mortgage, the "First Mortgages").  Reference is made to the First

applicable Mortgage Trustee in respect thereof, the duties and immunities of the
applicable Mortgage Trustee, the terms and conditions upon which the Pledged
First Mortgage Bonds are secured and the circumstances under which additional
first mortgage bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN PLEDGED
FIRST MORTGAGE BONDS) ISSUED UNDER EITHER OF THE FIRST MORTGAGES HAVE BEEN
RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE FIRST MORTGAGE
BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH THE
APPLICABLE FIRST MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF (THE
"SUBSTITUTION DATE"), THE PLEDGED FIRST MORTGAGE BONDS SHALL CEASE TO SECURE THE
NOTES IN ANY MANNER, AND, AT THE OPTION OF THE COMPANY, THE NOTES EITHER (A)
WILL

<PAGE>
 
BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (B) WILL BE SECURED BY
FIRST MORTGAGE BONDS ISSUED UNDER AN INDENTURE OTHER THAN THE FIRST MORTGAGES.
IN CERTAIN CIRCUMSTANCES PRIOR TO THE SUBSTITUTION DATE AS PROVIDED IN THE
INDENTURE, THE COMPANY IS PERMITTED TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF
AN ISSUE OF PLEDGED FIRST MORTGAGE BONDS HELD BY THE TRUSTEE, BUT IN NO EVENT
PRIOR TO THE SUBSTITUTION DATE TO AN AMOUNT LESS THAN THE AGGREGATE PRINCIPAL
AMOUNT OF THE RELATED ISSUE OF NOTES INITIALLY ISSUED CONTEMPORANEOUSLY WITH
SUCH PLEDGED FIRST MORTGAGE BONDS.

     Each Note shall be dated and issued as of the date of its authentication by
the Trustee and shall bear an Original Issue Date or Dates.  Each Note or Global
Note issued upon transfer, exchange or substitution of such Note or Global Note
shall bear the Original Issue Date or Dates of such transferred, exchanged or
substituted Note or Global Note, as the case may be.

     [If applicable, one of the following two sentences: This Global Note may
not be redeemed prior to ____________, _____.  This Global Note is not
redeemable prior to the Maturity Date set forth on the first page hereof.]  [If
applicable:  On or after _______________, ____, this Global Note is redeemable
in whole or in part in increments of $1,000 (provided that any remaining
principal amount of this Global Note shall be at least $100,000) at the option
of the Company at the following redemption prices (expressed as a percentage of
the principal amount to be redeemed) plus accrued interest to the redemption
date:


           Redemption Periods                   Redemption Prices
- ------------------------------------- ------------------------------------------


     Notice of redemption will be given by mail to Holders of Notes of this
issue not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture.  In the event of redemption of
this Global Note in part only, a new Global Note or Notes of like tenor and
series for the unredeemed portion hereof will be issued in the name of the
Noteholder hereof upon the surrender hereof.]

     Interest payments for this Global Note shall be computed and paid on the
basis of a 360-day year of twelve 30-day months.  If any Interest Payment Date
or the date on which the principal of this Global Note is required to be paid is
not a Business Day, then payment of principal, premium or interest need not be
made on such date

                                      A-4
<PAGE>
 
but may be made on the next succeeding Business Day with the same force and
effect as if made on such Interest Payment Date or date on which the principal
of this Global Note is required to be paid and, in the case of timely payment
thereof no interest shall accrue for the period from and after such Interest
Payment Date or the date on which the principal of this Global Note is required
to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations as specifically set forth
in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.

     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the Indenture and, upon such declaration, the Trustee can demand the
redemption of the Pledged First Mortgage Bonds as provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modifications.  Any such consent or waiver by the Holder of this Global Note
shall be conclusive and binding upon such Holder and upon all future Holders of
this Global Note and of any Note issued upon the registration of transfer hereof
or in exchange therefor or in lieu thereof whether or not notation of such
consent or waiver is made upon the Note.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered

                                      A-5
<PAGE>
 
reasonable indemnity to the Trustee to institute such proceeding as Trustee and
the Trustee shall have failed to institute such proceeding within 60 days;
provided that such limitations do not apply to a suit instituted by the Holder
hereof for the enforcement of payment of the principal of and any premium or
interest on this Note on or after the respective due dates expressed herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, this Global Note may be transferred only as permitted by the legend
hereto.

     If at any time the Depositary for this Global Note notifies the Company
that it is unwilling or unable to continue as Depositary for this Global Note or
if at any time the Depositary for this Global Note shall no longer be eligible
or in good standing under the Securities Exchange Act of 1934, as amended, or
other applicable statute or regulation, the Company shall appoint a successor
Depositary with respect to this Global Note.  If a successor Depositary for this
Global Note is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company's
election to issue this Note in global form shall no longer be effective with
respect to this Global Note and the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of individual
Notes in exchange for this Global Note, will authenticate and deliver individual
Notes of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of this Global Note.

     The Company may at any time and in its sole discretion determine that all
Notes of this series (but not less than all) issued or issuable in the form of
one or more Global Notes shall no longer be represented by such Global Note or
Notes.  In such event, the Company shall execute, and the Trustee, upon receipt
of a Company Order for the authentication and delivery of individual Notes in
exchange for such Global Note, shall authenticate and deliver, individual Notes
of like tenor and terms in definitive form in an aggregate principal amount
equal to the principal amount of such Global Note or Notes in exchange for such
Global Note or Notes.

     Under certain circumstances specified in the Indenture, the Depositary may
be required to surrender any two or more Global Notes which have identical terms
(but which may have differing Original Issue Dates) to the Trustee, and the
Company shall execute and the Trustee shall authenticate and deliver to, or at
the direction of, the

                                      A-6
<PAGE>
 
Depositary a Global Note in principal or amount equal to the aggregate principal
amount of, and with all terms identical to, the Global Notes surrendered thereto
and that shall indicate all Original Issue Dates and the principal amount
applicable to each such Original Issue Date.

     The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the state of Washington.

     Unless the certificate of authentication hereon has been executed by the
Trustee, directly or through an Authenticating Agent by manual signature of an
authorized officer, this Global Note shall not be entitled to any benefit under
the Indenture or be valid or obligatory for any purpose.

     All capitalized terms used but not otherwise defined in this Global Note
shall have the respective meanings assigned to them in the Indenture unless
otherwise indicated herein.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

NOTES IN ANY MANNER, AND, AT THE OPTION OF THE COMPANY, THE NOTES EITHER (A)
WILL BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (B) WILL BE SECURED
BY FIRST MORTGAGE BONDS ISSUED UNDER AN INDENTURE OTHER THAN THE FIRST
MORTGAGES.  IN CERTAIN CIRCUMSTANCES PRIOR TO THE SUBSTITUTION DATE AS PROVIDED
IN THE INDENTURE, THE COMPANY IS PERMITTED TO REDUCE THE AGGREGATE PRINCIPAL
AMOUNT OF A SERIES OF PLEDGED FIRST MORTGAGE BONDS HELD BY THE TRUSTEE, BUT IN
NO EVENT PRIOR TO THE SUBSTITUTION DATE TO AN AMOUNT LESS THAN THE AGGREGATE
OUTSTANDING PRINCIPAL AMOUNT OF THE RELATED ISSUE OF NOTES INITIALLY ISSUED
CONTEMPORANEOUSLY WITH SUCH PLEDGED FIRST MORTGAGE BONDS.

     [If applicable, one of the following two sentences: This Note may not be
redeemed prior to ____________, _____.  This Note is not redeemable prior to the

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


     Notice of redemption will be given by mail to Holders of Notes of this
issue not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture.  In the event of redemption of
this Note in part only, a new Note or Notes of like tenor for the unredeemed
portion hereof will be issued in the name of the Noteholder hereof upon the
surrender hereof.]

     Interest payments for this Note shall be computed and paid on the basis of
a 360-day year of twelve 30-day months.  If any Interest Payment Date or the
date on which the principal of this Note is required to paid is not a Business
Day, then payment of principal, premium or interest need not be made on such
date but may be made on the next succeeding Business Day with the same force and
effect as if made on such Interest Payment Date or the date on which the
principal of this Note is

                                      B-5
<PAGE>
 
required to be paid, and, in the case of timely payment thereof, no interest
shall accrue for the period from and after such Interest Payment Date or the

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations as specifically set forth
in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.

     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the Indenture and, upon such declaration, the Trustee can demand the
redemption of the Pledged First Mortgage Bonds as provided in the Indenture.

amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modifications.  Any such consent or waiver by the Holder of this Note shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange therefor in lieu thereof whether or not notation of such consent or
waiver is made upon the Note.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the

                                      B-6

enforcement of payment of the principal of and any premium or interest on this
Note on or after the respective due dates expressed herein.

absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the times, places and rates and the coin or currency prescribed
in the Indenture.

Company and the Note registrar, duly executed by the Holder hereof or the
attorney in fact of such Holder duly authorized in writing, one or more new
Notes of like tenor and of authorized denominations and for the same aggregate
principal amount will be issued to the designated transferee or transferees.

coupons, in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,

surrendering the same.

exchange but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

Original Issue Date (or if this Global Note has two or more Original Issue
Dates, interest shall, beginning on each such Original Issue Date, begin to

punctually paid or duly provided for on any such Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Note is
registered at the close of business on the Regular Record Date for such

     This Global Note is a global security in respect of a duly authorized issue
of Senior Notes, Series ___ (the "Notes of this Series," which term includes any
Global Notes representing such Notes) of the Company issued and to be issued
under an Indenture dated as of ________, 1997 between the Company and State
Street Bank and Trust, Boston, Massachusetts, as trustee (the "Trustee," which
term includes any successor Trustee under the Indenture) and indentures
supplemental thereto (collectively, the "Indenture").  Under the Indenture, one
or more series of notes may be issued and, as used herein, the term "Notes"
refers to the Notes of this series and any other outstanding series of Notes.
Reference is hereby made to the Indenture for a more complete statement of the
respective rights, limitations of rights, duties and immunities under the
Indenture of the Company, the Trustee and the Noteholders and of the terms upon
which the Notes are and are to be authenticated and delivered.  This Global Note
has been issued in respect of the series designated on the first page hereof
limited in aggregate principal amount to $__________.

     [Include the following paragraph if the Company elects to issue Pledged
Substituted Mortgage Bonds (as defined in the Indenture):  The Notes will be
secured by first mortgage bonds (the "Pledged First Mortgage Bonds") delivered
by the Company to the Trustee for the benefit of the Holders of the Notes,
issued under [the Substituted Mortgage (as defined in the Indenture)] from the
Company to ________________, as trustee (the "Mortgage Trustee"), as
supplemented and amended (the "First Mortgage").  Reference is made to the First
Mortgage and the Indenture for a description of the rights of the Trustee as
holder of the Pledged First Mortgage Bonds, the property mortgaged and pledged
under the First Mortgage, the rights of the Company and of the Mortgage Trustee
in respect thereof, the duties and immunities of the Mortgage Trustee, the terms
and conditions upon which the Pledged First Mortgage Bonds are secured and the
circumstances under which additional first mortgage bonds may be issued.]

     Each Note shall be dated and issued as of the date of its authentication by
the Trustee and shall bear an Original Issue Date or Dates.  Each Note or Global
Note issued upon transfer, exchange or substitution of such Note or Global Note
shall bear the Original Issue Date or Dates of such transferred, exchanged or
substituted Note or Global Note, as the case may be.

     [If applicable, one of the following two sentences: This Global Note may
not be redeemed prior to ____________, ____.  This Global Note is not redeemable
prior to the Maturity Date set forth on the first page hereof.]  [If applicable:
On or after _______________, ____, this Global Note is redeemable in whole or in
part in increments of $1,000 (provided that any remaining principal amount of
this Global Note shall be at least $100,000) at the option of the Company at the
following

                                      C-3
<PAGE>
 
redemption prices (expressed as a percentage of the principal amount to be
redeemed) plus accrued interest to the redemption date:

           Redemption Periods                          Redemption Prices
- ----------------------------------------  --------------------------------------



Notice of redemption will be given by mail to Holders of Notes of this issue not
less than 30 or more than 60 days prior to the date fixed for redemption, all as
provided in the Indenture.  In the event of redemption of this Global Note in
part only, a new Global Note or Notes of like tenor and series for the
unredeemed portion hereof will be issued in the name of the Noteholder hereof
upon the surrender hereof.]

     Interest payments for this Global Note shall be computed and paid on the
basis of a 360-day year of twelve 30-day months.  If any Interest Payment Date
or the date on which the principal of this Global Note is required to be paid is
not a Business Day, then payment of principal, premium or interest need not be
made on such date but may be made on the next succeeding Business Day with the
same force and effect as if made on such Interest Payment Date or date on which
the principal of this Global Note is required to be paid and, in the case of
timely payment thereof no interest shall accrue for the period from and after
such Interest Payment Date or the date on which the principal of this Global
Note is required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations specifically as set forth
in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.

     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the Indenture.

                                      C-4

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modifications.  Any such consent or waiver by the Holder of this Global Note
shall be conclusive and binding upon such Holder and upon all future Holders of
this Global Note and of any Note issued upon the registration of transfer hereof
or in exchange therefor or in lieu thereof whether or not notation of such
consent or waiver is made upon the Note.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal of and any premium or interest on this Note on or after the
respective due dates expressed herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, this Global Note may be transferred only as permitted by the legend
hereto.

     If at any time the Depositary for this Global Note notifies the Company
that it is unwilling or unable to continue as Depositary for this Global Note or
if at any time the Depositary for this Global Note shall no longer be eligible
or in good standing under the Securities Exchange Act of 1934, as amended, or
other applicable statute or regulation, the Company shall appoint a successor
Depositary with respect to this Global Note.  If a successor Depositary for this
Global Note is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company's
election to issue this Note in global form shall no longer be effective with
respect to this Global Note and the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery

                                      C-5

of individual Notes in exchange for this Global Note, will authenticate and
deliver individual Notes of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of this Global Note.

     The Company may at any time and in its sole discretion determine that all
Notes (but not less than all) issued or issuable in the form of one or more
Global Notes shall no longer be represented by such Global Note or Notes.  In
such event, the Company shall execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of individual Notes in
exchange for such Global Note, shall authenticate and deliver, individual Notes
of like tenor and terms in definitive form in an aggregate principal amount
equal to the principal amount of such Global Note or Notes in exchange for such
Global Note or Notes.

     Under certain circumstances specified in the Indenture, the Depositary may
be required to surrender any two or more Global Notes which have identical terms
(but which may have differing Original Issue Dates) to the Trustee, and the
Company shall execute and the Trustee shall authenticate and deliver to, or at
the direction of, the Depositary a Global Note in principal or amount equal to
the aggregate principal amount of, and with all terms identical to, the Global
Notes surrendered thereto and that shall indicate all Original Issue Dates and
the principal amount applicable to each such Original Issue Date.

     The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the state of Washington.

     Unless the certificate of authentication hereon has been executed by the
Trustee, directly or through an Authenticating Agent by manual signature of an
authorized officer, this Global Note shall not be entitled to any benefit under
the Indenture or be valid or obligatory for any purpose.

     All capitalized terms used but not otherwise defined in this Global Note
shall have the respective meanings assigned to them in the Indenture unless
otherwise indicated herein.

                                                                         DOLLARS

on the Maturity Date set forth above, and to pay interest thereon from the
Original Issue Date set forth above or from the most recent date to which
interest has been paid or duly provided for, semiannually in arrears on
__________ and __________ in each year (each, an "Interest Payment Date"),
commencing on the first such Interest Payment Date succeeding the Original Issue
Date set forth above, at the per annum Interest Rate set forth above, until the
principal hereof is paid or made available for payment.  No interest shall
accrue on the Maturity Date, so long as the principal amount of this Note is
paid in full on the Maturity Date.  The interest so payable and punctually paid
or duly provided, further, for on any such Interest Payment Date will, as
provided in the Indenture (as defined below), be paid to the Person in whose
name this Note is registered at the close of business on the Regular Record Date
for such interest, which shall be the __________ or __________ , as the case may
be, next preceding such Interest Payment Date; provided that the first Interest
Payment Date for any Note, the Original Issue Date of which is after a Regular
Record Date but prior to the applicable Interest Payment Date, shall be the
Interest Payment Date following the next succeeding Regular Record Date; and
provided, further, that interest payable on the Maturity Date set forth above
or, if applicable, upon redemption or acceleration, shall be payable to the
Person to whom principal shall be payable.  Except as otherwise provided in the
Indenture (referred to on the reverse 

                                      D-1
<PAGE>
 
hereof), any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and
shall be paid to the Person in whose name this Note is registered at the close
of business on a Special Record Date for the payment of such defaulted interest
to be fixed by the Trustee, notice whereof shall be given to Noteholders not
more than 15 days nor fewer than 10 days prior to such Special Record Date.
Principal, applicable premium and interest due at the maturity of this Note
shall be payable in immediately available funds when due upon presentation and
surrender of this Note at the corporate trust office of the Trustee or at the
authorized office of any paying agent. Interest on this Note (other than
interest payable at maturity) shall be paid by check or wire transfer payable in
clearinghouse funds to the Holder as its name appears on the register; provided,
that if the Trustee receives a written request from any Holder of Notes, the
aggregate principal amount of which having the same Interest Payment Date as
this Note equals or exceeds $10,000,000, on or before the applicable Regular
Record Date, interest on the Note shall be paid by wire transfer of immediately
available funds to a bank designated by such Holder in its request or by direct
deposit into the account of such Holder designated by such Holder in its request
if such account is maintained with the Trustee or any Paying agent.

     REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH
IN FULL ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof directly or through an Authenticating
Agent by manual signature of an authorized officer, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

                              SENIOR NOTE, SERIES

     This Note is one of a duly authorized issue of Senior Notes, Series ___
(the "Notes of this Series") of the Company issued and to be issued under an
Indenture dated as of ________, 1997, between the Company and State Street Bank
and Trust, Boston, Massachusetts, as trustee (herein called the "Trustee"),
which term includes any successor Trustee under the Indenture) and indentures
supplemental thereto (collectively, the "Indenture").  Under the Indenture, one
or more series of notes may be issued and, as used herein, the term "Notes"
refers to the Notes of this series and any other outstanding series of Notes.
Reference is hereby made for a more complete statement of the respective rights,
limitations of rights, duties and immunities under the Indenture of the Company,
the Trustee and the Noteholders and of the terms upon which the Notes are and
are to be authenticated and delivered.  This Note is one of the series
designated on the face hereof limited in aggregate principal amount to
$__________.

     [Include the following paragraph if the Company elects to issue Pledged
Substituted Mortgage Bonds (as defined in the Indenture):  The Notes will be
secured by first mortgage bonds (the "Pledged First Mortgage Bonds") delivered
by the Company to the Trustee for the benefit of the Holders of the Notes,
issued under [the Substituted Mortgage (as defined in the Indenture)] from the
Company to ________________, as trustee (the "Mortgage Trustee"), as
supplemented and amended (the "First Mortgage").  Reference is made to the First
Mortgage and the Indenture for a description of the rights of the Trustee as
holder of the Pledged First Mortgage Bonds, the property mortgaged and pledged
under the First Mortgage, the rights of the Company and of the Mortgage Trustee
in respect thereof, the duties and immunities of the Mortgage Trustee, the terms
and conditions upon which the Pledged First Mortgage Bonds are secured and the
circumstances under which additional first mortgage bonds may be issued.]

     [If applicable, one of the following two sentences:  This Note may not be
redeemed prior to __________, ____.  This Note is not redeemable prior to the
Maturity Date set forth on the face hereof.]  [If applicable: On or after
________, ____, this Note is redeemable in whole or in part in increments of
$1,000 (provided that any remaining principal amount of this Note shall be at
least $1,000) at the option of the Company at the following redemption prices
(expressed as a percentage of the principal amount to be redeemed) plus accrued
interest to the redemption date:

<PAGE>
 
           Redemption Periods                      Redemption Prices
- ------------------------------------- ------------------------------------------



     Notice of redemption will be given by mail to Holders of Notes of this
issue not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture.  In the event of redemption of
this Note in part only, a new Note or Notes of like tenor for the unredeemed
portion hereof will be issued in the name of the Noteholder hereof upon the
surrender hereof.]

     Interest payments for this Note shall be computed and paid on the basis of
a 360-day year of twelve 30-day months.  If any Interest Payment Date or the
date on which the principal of this Note is required to paid is not a Business
Day, then payment of principal, premium or interest need not be made on such
date but may be made on the next succeeding Business Day with the same force and
effect as if made on such Interest Payment Date or the date on which the
principal of this Note is required to be paid, and, in the case of timely
payment thereof, no interest shall accrue for the period from and after such
Interest Payment Date or the date on which the principal of this Note is
required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations as specifically set forth
in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.

     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the

                                      D-5
<PAGE>
 
Indenture and, upon such declaration, the Trustee can demand the redemption of
the Pledged First Mortgage Bonds as provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modification.  Any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange
therefor in lieu thereof whether or not notation of such consent or waiver is
made upon the Note.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal of and any premium or interest on this Note on or after the
respective due dates expressed herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Note register.  Upon
surrender of this Note for registration or transfer at the corporate trust
office of the Trustee or such other office or agency as may be designated by the
Company in the Borough of Manhattan, the City and State of New York, endorsed by
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Note registrar, duly executed by the Holder hereof or the
attorney in fact of such Holder duly authorized in writing, one or more new
Notes of like tenor and of authorized denominations and for the same aggregate
principal amount will be issued to the designated transferee or transferees.

                                      D-6

     The Notes of this series are issuable only in registered form, without
coupons, in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Notes are exchangeable for a like aggregate principal amount of Notes of like
tenor and of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner thereof for all
purposes, whether or not this Note is overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the state of Washington.

     All capitalized terms used but not otherwise defined in this Note shall
have the respective meanings assigned to them in the Indenture.

Puget Sound Energy, Inc.
411 - 108th Avenue N.E.
Bellevue, WA  98004-5515

Ladies and Gentlemen:

     This opinion is furnished in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of $500,000,000 aggregate
principal amount of Senior Notes (the "Notes") of Puget Sound Energy, Inc. (the
"Company") pursuant to the Company's Registration Statement on Form S-3 filed
with the Securities and Exchange Commission on the date hereof (the
"Registration Statement").

     We have examined the Registration Statement and such other documents and
records of the Company, certificates of public officials, and other documents as
we have deemed necessary or appropriate for the purposes of this opinion.
Capitalized terms used but not otherwise defined herein have the respective
meanings assigned to such terms in the Registration Statement.

     Based upon the foregoing, we are of the opinion that, when the following
events have occurred:

     (a) the Board of Directors of the Company has duly authorized (i) the
issuance and sale of the Notes, (ii) the execution and delivery of an Indenture
(the "Indenture") between the Company and State Street Bank and Trust Company
(the "Note Trustee") and an indenture supplemental thereto pursuant to which the
Company will issue a series of Notes, (iii) the issuance and delivery of Pledged
Bonds to the Note Trustee to secure the Company's obligations under the Notes
and (iv) the execution and delivery of an indenture supplemental to the Electric
Utility Mortgage or the Gas Utility Mortgage, as the case may be, pursuant to
which the Company will issue a series of Pledged Bonds (the "Pledged Bond
Supplemental Indenture");

<PAGE>
 
November 25, 1997

     (b) the Washington Utilities and Transportation Commission has issued the
appropriate orders authorizing the issuance and sale of the Notes and the
issuance of the Pledged Bonds;

     (c) the Registration Statement and any amendments or supplements thereto
have been filed, and the Registration Statement has become effective;

     (d) the terms of the Notes and their issue and sale have been duly
established in conformity with the Indenture so as not to violate any applicable
law, agreement or instrument then binding upon the Company;

     (e) the terms of the Pledged Bonds and their issue have been duly
established in conformity with the Electric Utility Mortgage or Gas Utility
Mortgage, as the case may be, so as not to violate any applicable law, agreement
or instrument then binding upon the Company;

     (f) the Company having complied with the terms and conditions of the
Indenture with respect to the creation, authentication and delivery of a
supplemental indenture thereto;

     (g) the due execution by the Company and authentication and delivery by the
Note Trustee of the Notes, and the issuance and sale thereof by the Company as
contemplated by the Registration Statement and in accordance with the above-
mentioned corporate and governmental authorizations;

     (h) the Company having complied with the terms and conditions of the
Electric Utility Mortgage or the Gas Utility Mortgage, as the case may be, with
respect to the creation, authentication and delivery of a supplemental indenture
thereto;

     (i) the due execution by the Company and authentication and delivery by the
Electric Utility Mortgage Trustee or the Gas Utility Mortgage Trustee, as the
case may be, of the Pledged Bonds, and the issuance thereof by the Company as
contemplated by the Registration Statement and in accordance with the above-
mentioned corporate and governmental authorizations; and

     (j) the Pledged Bond Supplemental Indenture has been duly filed and
recorded in the appropriate recording offices of all jurisdictions in which the
properties subject to the Electric Utility Mortgage or the Gas Utility Mortgage,
as the
<PAGE>
 
November 25, 1997

case may be, are located, and all appropriate Uniform Commercial Code filings
have been duly filed and recorded;

the Notes will constitute in the hands of the respective holders thereof valid
and binding obligations of the Company, subject to applicable bankruptcy and
insolvency laws and the application of general principles of equity.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal
Matters" in the related 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,
