                         PROSPECTUS SUPPLEMENT SUMMARY

    THE  FOLLOWING  SUMMARY  IS QUALIFIED  IN  ITS  ENTIRETY BY,  AND  SHOULD BE
CONSIDERED  IN  CONJUNCTION  WITH,  THE  INFORMATION  AND  FINANCIAL  STATEMENTS
APPEARING   ELSEWHERE  IN  THIS  PROSPECTUS   SUPPLEMENT  AND  THE  ACCOMPANYING
PROSPECTUS AND THE DOCUMENTS INCORPORATED THEREIN BY REFERENCE.

                                  THE COMPANY

    The  principal  business  of   Northwestern  Public  Service  Company   (the
"Company") is energy distribution. The Company is engaged in providing regulated
electric  and natural  gas service  in South Dakota  and natural  gas service in
Nebraska. The Company serves approximately 54,900 electric customers and  75,000
gas  customers  representing  a  diverse  mix  of  residential,  commercial  and
industrial customers. In  addition, the  Company has  investments in  nonutility
businesses  and has  recently contracted  to acquire  Synergy Group Incorporated
("Synergy"), a  major  propane  distribution  company.  See  "The  Company"  and
"Pending   Acquisition  of  Synergy  Group  Incorporated"  in  the  accompanying
Prospectus.

    The  Company's  electric  business  generates,  transmits  and   distributes
electricity to over 100 communities in eastern South Dakota. In 1994, 46% of the
Company's  total operating  revenues were from  the sale of  electric energy. At
December  31,  1994,  the  aggregate  capacity  of  all  Company-owned  electric
generating  units was  309,000 kilowatts ("kw"),  consisting of  202,000 kw from
jointly-owned baseload plants  and 107,000 kw  from internal combustion  turbine
and  diesel  units used  primarily for  peaking purposes.  All of  the Company's
baseload plants  are fueled  by  coal. The  Company has  maintained  competitive
electric  rates when  compared to  neighboring utilities  and has  a competitive
electric baseload  generating production  cost, which  includes fuel  and  plant
operating expenses, of less than 1.5 CENTS per kilowatt hour.

    The  Company's natural  gas business  purchases, transports  and distributes
natural gas to over 50 communities in eastern South Dakota and 4 communities  in
central  Nebraska. In 1994,  40% of the Company's  total operating revenues were
from the sale of natural gas. The Company purchases gas supply from more than 20
domestic and Canadian suppliers and  transports natural gas supply through  five
pipelines.  Gas  agreements provide  for firm  deliverable pipeline  capacity of
approximately 98,900  million  british  thermal units  ("MMBTU"),  per  day.  To
supplement  firm gas supplies,  the Company owns six  propane-air plants and has
contracts for underground natural gas storage services. Over the last five years
the Company  has  expanded its  gas  distribution  operations to  serve  29  new
communities in South Dakota.

    The Company's business strategy is summarized by three primary objectives:

    - To  enhance the Company's competitive  position in its energy distribution
      businesses;

    - To  expand  energy  sales  and  markets  with  value-added  services   for
      customers; and

    - To  provide earnings and  dividend growth and  increased shareholder value
      through its energy distribution businesses and investment and  acquisition
      activities.

By  enhancing the competitive position of its core electric and gas distribution
businesses and expanding its energy sales  and markets, the Company believes  it
will  position itself to be successful  in the increasingly competitive electric
and gas  distribution businesses  anticipated over  the next  several years.  To
supplement  growth strategies  in its electric  and natural  gas businesses, the
Company also plans  to seek  new investment and  acquisition opportunities  that
have  demonstrable growth potential.  The primary focus  of these investment and
acquisition activities  is  targeted  in  energy  distribution  businesses.  The
Company  also  plans  to  pursue  opportunities  in  non-energy  businesses that
complement its  existing  operations  and  provide  the  capability  to  enhance
shareholder value.

    In  May 1995,  the Company contracted  to acquire Synergy,  a retail propane
distributor serving over 200,000  customers from 152 locations  in 23 states  in
the  eastern and south central  regions of the U.S.  See "Pending Acquisition of
Synergy   Group    Incorporated"   in    the   accompanying    Prospectus.    In

                                      S-3

accordance  with  its  strategic plan,  the  Company believes  that  the Synergy
propane distribution operations are complementary to the Company's electric  and
natural  gas businesses.  Propane is the  nation's fourth  largest energy source
after electricity, natural gas  and fuel oil. The  acquisition price to be  paid
for  Synergy is $137.5 million cash (subject to certain adjustments) and certain
securities of the Company's acquisition subsidiary. The Company has entered into
an agreement with a third party for the sale of certain Synergy properties which
will reduce the  cash portion  of the  acquisition price  to approximately  $100
million.  The  Company  has  executed a  management  agreement  with  Empire Gas
Corporation ("Empire Gas") for the joint management of the properties after  the
acquisition.  Empire  Gas  is  the  nation's  eleventh  largest  retail  propane
distributor. Subsequent to the  acquisition and expected  third party sale,  the
Company's  total  assets  will consist  of  approximately 65%  electric  and gas
distribution, 25% propane distribution and  10% marketable securities and  other
diversified investments.

    The  Company's principal  executive offices are  located at  33 Third Street
S.E., Huron,  South  Dakota  57350.  The Company's  telephone  number  is  (605)
352-8411.

                                USE OF PROCEEDS

    The  net proceeds from the sale of  approximately $50 million of the Offered
Bonds will be  applied to  fund the  acquisition of  Synergy, including  certain
transaction  expenses. The additional net proceeds  from the sale of the Offered
Bonds will be  applied to  repay short  term debt of  the Company.  See "Use  of
Proceeds" in the accompanying Prospectus.

                       CERTAIN TERMS OF THE OFFERED BONDS

    GENERAL.   The  Offered Bonds are  being issued under  the Company's General
Mortgage Indenture  and Deed  of Trust  dated as  of August  1, 1993  (the  "New
Mortgage")   between  the  Company  and   The  Chase  Manhattan  Bank  (National
Association), as  trustee  (the  "New Mortgage  Trustee"),  as  supplemented  by
various  supplemental indentures, including the  Supplemental Indenture dated as
of                   , 1995  relating to  the Offered  Bonds (the  "Supplemental
Indenture").  The Offered Bonds will be issued  on the basis of a First Mortgage
Bond in the principal amount of  $       (the "Pledged Bond") issued to the  New
Mortgage  Trustee under the Company's Indenture dated August 1, 1940 (the "First
Mortgage")  between  the  Company  and   The  Chase  Manhattan  Bank   (National
Association)  and C. J.  Heinzelmann, as successor  Trustees, as supplemented by
various supplemental indentures, including  the supplemental indenture dated  as
of             , 1995 relating to the Pledged Bond, and on the basis of property
additions.  The Offered Bonds  will be secured,  in part, by  the First Mortgage
Bonds (including the Pledged Bond) held  by the New Mortgage Trustee. The  First
Mortgage   constitutes,  subject  to   certain  exceptions,  a   first  lien  on
substantially all properties  of the  Company. The  Offered Bonds  will also  be
secured  by the lien of the New Mortgage on the Company's properties used in the
generation, production,  transmission  or  distribution of  electricity  or  the
distribution  of gas  in any  form and for  any purpose  in the  States of South
Dakota or Nebraska, which lien is junior to the lien of the First Mortgage.  See
"Description of the Mortgage Bonds" in the accompanying Prospectus.

    The  following  summaries of  certain provisions  of  the New  Mortgage, the
Supplemental Indenture and the Offered Bonds  (referred to in the Prospectus  as
"Mortgage  Bonds") hereby supplement,  and to the  extent inconsistent therewith
replace, the description  of the general  terms and provisions  of the  Mortgage
Bonds  set forth under "Description of the Mortgage Bonds" in the Prospectus, to
which description  reference is  hereby  made. The  following summaries  do  not
purport  to be complete and are subject  to, and are qualified in their entirety
by reference  to,  the provisions  of  the  New Mortgage  and  the  Supplemental
Indenture.  The following makes use of defined terms in the New Mortgage and the
Supplemental Indenture.

    BOOK-ENTRY SYSTEM.    The  Offered Bonds  will  be  issued in  the  form  of
fully-registered  book-entry Offered Bonds  which will be  deposited with, or on
behalf of, The Depository Trust Company (the "Depositary") and registered in the
name of the Depositary's nominee (each, a "Book-Entry Security"). Except as  set
forth  below, a Book-Entry Security may not  be transferred except as a whole by
the Depositary or by a nominee of the Depositary to the Depositary, by a nominee
of the Depositary to another nominee of  the Depositary or by the Depositary  or
any  such  nominee  to  a successor  of  the  Depositary or  a  nominee  of such
successor.

    The Depositary has  advised the Company  and the Underwriters  that it is  a
limited-purpose trust company organized under the laws of the State of New York,
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, as amended.  The Depositary was created  to hold securities of its
participants and  to  facilitate  the clearance  and  settlement  of  securities
transactions  among  the  participants  in  such  securities  through electronic
book-entry changes in accounts of the participants, thereby eliminating the need
for physical movement of securities certificates. The Depositary's  participants
include  securities  brokers and  dealers  (including the  Underwriters), banks,
trust companies, clearing corporations and certain

                                      S-6

other organizations,  some  of  whom  (and/or  their  representatives)  own  the
Depositary.  Access to the  Depositary's book-entry system  is also available to
others, such as banks, brokers, dealers  and trust companies that clear  through
or  maintain a  custodial relationship  with a  participant, either  directly or
indirectly. Persons who  are not  participants may  beneficially own  securities
held  by the Depositary  only through participants. The  rules applicable to the
Depositary are on file with the Securities and Exchange Commission.

    Upon  the  issuance  by  the  Company  of  the  Book-Entry  Securities,  the
Depositary  will credit, on its book-entry registration and transfer system, the
principal amount of the Offered Bonds represented by such Book-Entry  Securities
to the accounts of participants. The accounts to be credited shall be designated
by the applicable Underwriter. Ownership of beneficial interests in a Book-Entry
Security  will be  limited to  participants or  persons that  may hold interests
through participants.  Beneficial interests  in a  Book-Entry Security  will  be
shown  on,  and the  transfer  thereof will  be  effected only  through, records
maintained  by  the  Depositary  (with   respect  to  beneficial  interests   of
participants)  or by  participants, or persons  that may  hold interests through
participants (with respect  to beneficial interests  to beneficial owners).  The
laws  of some states require that certain purchasers of securities take physical
delivery of such securities in certificated form. Such limits and such laws  may
impair the ability to transfer beneficial interests in a Book-Entry Security.

    For  a Book-Entry Security, so long as  the Depositary or its nominee is the
registered owner of a Book-Entry Security, the Depositary or its nominee, as the
case may be, will be  considered the sole owner or  holder of the Offered  Bonds
represented by such Book-Entry Security for all purposes under the New Mortgage.
Except  as  provided  below,  owners of  beneficial  interests  in  a Book-Entry
Security will  not  be  entitled  to have  Offered  Bonds  represented  by  such
Book-Entry  Security registered in their names,  will not receive or be entitled
to receive physical delivery of such Offered Bonds in certificated form and will
not be considered the owners or holders thereof under the New Mortgage.

    Principal and interest payments on  Offered Bonds issued in book-entry  form
and  represented by the Book-Entry Securities will be made by the Company to the
Depositary or its nominee, as  the case may be, as  the registered owner of  the
related  Book-Entry Securities. The Company will  not have any responsibility or
liability for any aspect of the records relating to or payments made on  account
of   beneficial  ownership  interests  in  the  Book-Entry  Securities,  or  for
maintaining, supervising or  reviewing any records  relating to such  beneficial
ownership  interests. The Company  expects that the  Depositary, upon receipt of
any payment of principal  or interest in respect  of any Book-Entry  Securities,
will credit immediately the accounts of the related participants with payment in
amounts  proportionate to their respective  beneficial interest in the principal
amount of such Book-Entry Securities as shown on the records of the  Depositary.
The  Company also expects  the payments by participants  to owners of beneficial
interests in the  Book-Entry Securities  will be governed  by standing  customer
instructions  and customary practices,  as is now 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 participants.

    If the  Depositary  is  at any  time  unwilling  or unable  to  continue  as
depositary  and a successor depositary is not appointed by the Company within 90
days, the Company will issue Offered Bonds in certificated form in exchange  for
each Book-Entry Security. In addition, the Company may at any time determine not
to  have Offered  Bonds represented  by the  Book-Entry Securities.  In any such
instance, owners of beneficial interests  in such Book-Entry Securities will  be
entitled  to physical  delivery of Offered  Bonds in certificated  form equal in
principal amount to  such beneficial interests  and to have  such Offered  Bonds
registered  in its name.  Offered Bonds so  issued in certificated  form will be
issued in  denominations of  $1,000 or  any larger  amount that  is an  integral
multiple thereof and will be issued in registered form only, without coupons.

    SAME-DAY  PAYMENT AND SETTLEMENT.  All payments of principal of and interest
on the Offered Bonds will be made by the Company in same-day funds.

                                      S-7

    SECURITY.  The Offered Bonds will be issued on the basis of the Pledged Bond
and on the  basis of property  additions. The  Pledged Bond will  be issued  and
delivered  to, and registered  in the name  of, the New  Mortgage Trustee or its
nominee and will be owned and held  by the New Mortgage Trustee, subject to  the
provisions  of the New Mortgage,  for the benefit of  the Holders (as defined in
the accompanying  Prospectus) of  the Offered  Bonds and  all other  outstanding
Mortgage  Bonds issued  under the  New Mortgage,  and the  Company will  have no
interest in the Pledged Bond. The Pledged  Bond will be issued in the  principal
amount  of            and, as is the case with the Offered Bonds, will mature on
                 , will bear interest at the rate of      % per annum, and  will
be  payable semi-annually  on                  and                   , beginning
                 . Any payment by the Company  of principal of, or interest  on,
the  Pledged Bond shall be applied by the New Mortgage Trustee to the payment of
any principal, or interest, as the case may be, in respect of the Offered  Bonds
which  is then due and, to the extent of such application, the obligation of the
Company under the New Mortgage  to make such payment  in respect of the  Offered
Bonds  will be deemed satisfied and discharged. Any payment by the Company under
the New Mortgage of principal of, or interest on, the Offered Bonds will, to the
extent thereof, be deemed to satisfy and discharge the obligation of the Company
to make a corresponding payment of principal,  or interest, as the case may  be,
in respect of the Pledged Bond which is then due.

                                  UNDERWRITING

    Under  the terms and subject to the conditions contained in the Underwriting
Agreement dated the  date hereof,  the Underwriters named  below have  severally
agreed  to purchase,  and the  Company has agreed  to sell  to the Underwriters,
severally, the following respective principal amounts of the Offered Bonds:

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


    The Underwriting  Agreement provides  that the  obligations of  the  several
Underwriters  to pay for and accept delivery of the Offered Bonds are subject to
approval of certain legal  matters by counsel and  to certain other  conditions.
The  Underwriters are  committed to pay  for and  accept delivery of  all of the
Offered Bonds  if  any are  taken;  provided that  under  certain  circumstances
involving  a default of Underwriters, less than  all of the Offered Bonds may be
purchased.

    The Underwriters  initially  propose to  offer  part of  the  Offered  Bonds
directly  to the public at the public offering price set forth on the cover page
of this  Prospectus Supplement  and part  to certain  dealers at  a price  which
represents  a concession not in  excess of     % of the  principal amount of the
Offered Bonds.  The  Underwriters may  allow  and  such dealers  may  reallow  a
concession of    % of the principal amount of the Offered Bonds to certain other
dealers.  After the initial  public offering, the public  offering price and the
other selling items may be changed.

    Each series of Offered Bonds will be a new issue of securities and will have
no established trading  market. Any  Underwriter to  whom Offered  Bonds of  any
series are sold for public offering and sale may make a market in such series of
Offered  Bonds, but  such Underwriters will  not be  obligated to do  so and may
discontinue any market making  at any time without  notice. No assurance can  be
given as to the liquidity of, or trading market for, any Offered Bonds.

    The  Company  has  agreed  to  indemnify  the  Underwriters  against certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

    The Underwriters engage  in (or in  the future may  engage in)  transactions
with,  and perform services for,  the Company or its  affiliates in the ordinary
course of business. Morgan Stanley & Co.

                         PROSPECTUS SUPPLEMENT SUMMARY

    THE  FOLLOWING  SUMMARY  IS QUALIFIED  IN  ITS  ENTIRETY BY,  AND  SHOULD BE
CONSIDERED  IN  CONJUNCTION  WITH,  THE  INFORMATION  AND  FINANCIAL  STATEMENTS
APPEARING   ELSEWHERE  IN  THIS  PROSPECTUS   SUPPLEMENT  AND  THE  ACCOMPANYING
PROSPECTUS AND THE DOCUMENTS INCORPORATED THEREIN BY REFERENCE.

                                  THE COMPANY

    The  principal  business  of   Northwestern  Public  Service  Company   (the
"Company") is energy distribution. The Company is engaged in providing regulated
electric  and natural  gas service  in South Dakota  and natural  gas service in
Nebraska. The Company serves approximately 54,900 electric customers and  75,000
gas  customers  representing  a  diverse  mix  of  residential,  commercial  and
industrial customers. In  addition, the  Company has  investments in  nonutility
businesses  and has  recently contracted  to acquire  Synergy Group Incorporated
("Synergy"), a  major  propane  distribution  company.  See  "The  Company"  and
"Pending   Acquisition  of  Synergy  Group  Incorporated"  in  the  accompanying
Prospectus.

    The  Company's  electric  business  generates,  transmits  and   distributes
electricity to over 100 communities in eastern South Dakota. In 1994, 46% of the
Company's  total operating  revenues were from  the sale of  electric energy. At
December  31,  1994,  the  aggregate  capacity  of  all  Company-owned  electric
generating  units was  309,000 kilowatts ("kw"),  consisting of  202,000 kw from
jointly-owned baseload plants  and 107,000 kw  from internal combustion  turbine
and  diesel  units used  primarily for  peaking purposes.  All of  the Company's
baseload plants  are fueled  by  coal. The  Company has  maintained  competitive
electric  rates when  compared to  neighboring utilities  and has  a competitive
electric baseload  generating production  cost, which  includes fuel  and  plant
operating expenses, of less than 1.5 CENTS per kilowatt hour.

    The  Company's natural  gas business  purchases, transports  and distributes
natural gas to over 50 communities in eastern South Dakota and 4 communities  in
central  Nebraska. In 1994,  40% of the Company's  total operating revenues were
from the sale of natural gas. The Company purchases gas supply from more than 20
domestic and Canadian suppliers and  transports natural gas supply through  five
pipelines.  Gas  agreements provide  for firm  deliverable pipeline  capacity of
approximately 98,900  million  british  thermal  units  ("MMBTU")  per  day.  To
supplement  firm gas supplies,  the Company owns six  propane-air plants and has
contracts for underground natural gas storage services. Over the last five years
the Company  has  expanded its  gas  distribution  operations to  serve  29  new
communities in South Dakota.

    The Company's business strategy is summarized by three primary objectives:

    - To  enhance the Company's competitive  position in its energy distribution
      businesses;

    - To  expand  energy  sales  and  markets  with  value-added  services   for
      customers; and

    - To  provide earnings and  dividend growth and  increased shareholder value
      through its energy distribution businesses and investment and  acquisition
      activities.

By  enhancing the competitive position of its core electric and gas distribution
businesses and expanding its energy sales  and markets, the Company believes  it
will  position itself to be successful  in the increasingly competitive electric
and gas  distribution businesses  anticipated over  the next  several years.  To
supplement  growth strategies  in its electric  and natural  gas businesses, the
Company also plans  to seek  new investment and  acquisition opportunities  that
have  demonstrable growth potential.  The primary focus  of these investment and
acquisition activities  is  targeted  in  energy  distribution  businesses.  The
Company  also  plans  to  pursue  opportunities  in  non-energy  businesses that
complement its  existing  operations  and  provide  the  capability  to  enhance
shareholder value.

    In  May 1995,  the Company contracted  to acquire Synergy,  a retail propane
distributor serving over 200,000  customers from 152 locations  in 23 states  in
the  eastern and south central  regions of the U.S.  See "Pending Acquisition of
Synergy   Group    Incorporated"   in    the   accompanying    Prospectus.    In

                                      S-3

accordance  with  its  strategic plan,  the  Company believes  that  the Synergy
propane distribution operations are complementary to the Company's electric  and
natural  gas businesses.  Propane is the  nation's fourth  largest energy source
after electricity, natural gas  and fuel oil. The  acquisition price to be  paid
for  Synergy is $137.5 million cash (subject to certain adjustments) and certain
securities of the Company's acquisition subsidiary. The Company has entered into
an agreement with a third party for the sale of certain Synergy properties which
will reduce the  cash portion  of the  acquisition price  to approximately  $100
million.  The  Company  has  executed a  management  agreement  with  Empire Gas
Corporation ("Empire Gas") for the joint management of the properties after  the
acquisition.  Empire  Gas  is  the  nation's  eleventh  largest  retail  propane
distributor. Subsequent to the  acquisition and expected  third party sale,  the
Company's  total  assets  will consist  of  approximately 65%  electric  and gas
distribution, 25% propane distribution and  10% marketable securities and  other
diversified investments.

    The  Company's principal  executive offices are  located at  33 Third Street
S.E., Huron,  South  Dakota  57350.  The Company's  telephone  number  is  (605)
352-8411.

taken.

    The Underwriters propose to offer part  of the Common Stock directly to  the
public  at the public offering price set forth on the cover page hereof and part
to certain dealers  at a price  that represents  a concession not  in excess  of
$      per  share of Common Stock. The  Underwriters may allow, and such dealers

liabilities, including liabilities under the Securities Act of 1933, as amended.

additional 180,000 shares of Common Stock at the public offering price set forth
on the  cover page  hereof,  less underwriting  discounts and  commissions.  The
Underwriters  may  exercise  such  option solely  for  the  purpose  of covering
over-allotments, if any, incurred in the sale of the Common Stock.

    The Company has  agreed in  the Underwriting  Agreement not  to directly  or
indirectly  (1) offer, pledge, sell, contract or otherwise dispose of any Common
Stock or any securities convertible into or exchangeable for Common Stock or (2)
enter into any swap or  similar agreement that transfers,  in whole or in  part,
the  economic risk  of ownership of  Common Stock, whether  any such transaction
described in clause (1) or (2) is to  be settled by delivery of Common Stock  or
other  securities, in cash or otherwise, for a  period of 90 days after the date
of this  Prospectus Supplement,  without  the prior  written consent  of  Morgan
Stanley  & Co. Incorporated,  provided that the  Company may during  such 90 day
period issue shares under its dividend reinvestment, customer stock purchase and
other plans.

    Certain of  the Underwriters  engage in  (or in  the future  may engage  in)
transactions  with, and provide  services for, the Company  or its affiliates in

DISTRIBUTIONS OUT OF MONEYS HELD BY NWPS CAPITAL AND PAYMENTS ON LIQUIDATION  OF
NWPS  CAPITAL OR THE REDEMPTION OF PREFERRED SECURITIES, AS SET FORTH BELOW, ARE
GUARANTEED BY THE COMPANY (THE "GUARANTEE") TO THE EXTENT NWPS CAPITAL HAS FUNDS
LEGALLY AVAILABLE THEREFOR AS DESCRIBED UNDER "DESCRIPTION OF THE GUARANTEES" IN
THE ACCOMPANYING PROSPECTUS. THE OBLIGATIONS OF THE COMPANY UNDER THE  GUARANTEE
ARE  SUBORDINATE AND JUNIOR IN RIGHT OF  PAYMENT TO ALL OTHER LIABILITIES OF THE
COMPANY AND PARI PASSU WITH THE MOST SENIOR PREFERRED STOCK ISSUED FROM TIME  TO
TIME  BY THE COMPANY. THE OBLIGATIONS OF THE COMPANY UNDER THE SUBORDINATED DEBT
SECURITIES ARE SUBORDINATE  AND JUNIOR IN  RIGHT OF PAYMENT  TO ALL PRESENT  AND
FUTURE  SENIOR INDEBTEDNESS (AS DEFINED HEREIN) OF THE COMPANY, WHICH AGGREGATED
APPROXIMATELY $124  MILLION AT  MARCH 31,  1995, AND  RANK PARI  PASSU WITH  THE
COMPANY'S OTHER GENERAL UNSECURED CREDITORS.
    

   
    THE  DISTRIBUTION RATE AND THE DISTRIBUTION  AND OTHER PAYMENT DATES FOR THE
PREFERRED SECURITIES WILL CORRESPOND TO THE INTEREST RATE AND INTEREST AND OTHER
PAYMENT DATES ON THE SUBORDINATED DEBT SECURITIES, WHICH WILL BE THE SOLE ASSETS
OF NWPS  CAPITAL. AS  A RESULT,  IF PRINCIPAL  OR INTEREST  IS NOT  PAID ON  THE
SUBORDINATED  DEBT  SECURITIES,  NO  AMOUNTS  WILL  BE  PAID  ON  THE  PREFERRED
SECURITIES. IF THE COMPANY DOES NOT  MAKE PRINCIPAL OR INTEREST PAYMENTS ON  THE
SUBORDINATED  DEBT SECURITIES,  NWPS CAPITAL WILL  NOT HAVE  SUFFICIENT FUNDS TO
MAKE DISTRIBUTIONS ON THE  PREFERRED SECURITIES, IN  WHICH EVENT, THE  GUARANTEE
WILL  NOT APPLY  TO SUCH DISTRIBUTIONS  UNTIL NWPS CAPITAL  HAS SUFFICIENT FUNDS
LEGALLY AVAILABLE THEREFOR.
    

   
    THE COMPANY HAS THE RIGHT TO DEFER PAYMENTS OF INTEREST ON THE  SUBORDINATED
DEBT  SECURITIES BY  EXTENDING THE INTEREST  PAYMENT PERIOD  ON THE SUBORDINATED
DEBT SECURITIES  AT  ANY  TIME FOR  UP  TO  20 CONSECUTIVE  QUARTERS  (EACH,  AN
"EXTENSION  PERIOD"). IF INTEREST PAYMENTS ARE SO DEFERRED, DISTRIBUTIONS ON THE
PREFERRED  SECURITIES  WILL  ALSO  BE  DEFERRED.  DURING  AN  EXTENSION  PERIOD,
DISTRIBUTIONS  WILL  CONTINUE TO  ACCRUE WITH  INTEREST  THEREON (TO  THE EXTENT
PERMITTED BY APPLICABLE LAW)  AT AN ANNUAL RATE  OF     % PER ANNUM,  COMPOUNDED
QUARTERLY.  DURING ANY EXTENSION PERIOD, HOLDERS OF PREFERRED SECURITIES WILL BE
REQUIRED TO INCLUDE DEFERRED  INTEREST INCOME IN THEIR  GROSS INCOME FOR  UNITED
STATES   FEDERAL  INCOME  TAX  PURPOSES  IN  ADVANCE  OF  RECEIPT  OF  THE  CASH
DISTRIBUTIONS WITH RESPECT TO  SUCH DEFERRED INTEREST  PAYMENTS. THERE COULD  BE
MULTIPLE  EXTENSION  PERIODS  OF  VARYING LENGTHS  THROUGHOUT  THE  TERM  OF THE
SUBORDINATED  DEBT  SECURITIES.  SEE  "DESCRIPTION  OF  THE  SUBORDINATED   DEBT
SECURITIES  --  OPTION  TO  EXTEND  INTEREST  PAYMENT  PERIOD."  IF  THE COMPANY
EXERCISES THE RIGHT TO EXTEND AN INTEREST PAYMENT PERIOD, THE COMPANY SHALL  NOT
DURING  SUCH  EXTENSION  PERIOD (A)  DECLARE  OR  PAY DIVIDENDS  ON,  OR  MAKE A
DISTRIBUTION WITH  RESPECT  TO,  OR  REDEEM, PURCHASE  OR  ACQUIRE,  OR  MAKE  A
LIQUIDATION  PAYMENT WITH RESPECT TO, ANY OF  ITS CAPITAL STOCK AND (B) MAKE ANY
PAYMENT OF INTEREST, PRINCIPAL  OR PREMIUM, IF ANY,  ON OR REPAY, REPURCHASE  OR

                         PROSPECTUS SUPPLEMENT SUMMARY

   
    THE  FOLLOWING  SUMMARY  IS QUALIFIED  IN  ITS  ENTIRETY BY,  AND  SHOULD BE
CONSIDERED  IN  CONJUNCTION  WITH,  THE  INFORMATION  AND  FINANCIAL  STATEMENTS
APPEARING   ELSEWHERE  IN  THIS  PROSPECTUS   SUPPLEMENT  AND  THE  ACCOMPANYING
PROSPECTUS AND THE DOCUMENTS INCORPORATED THEREIN BY REFERENCE.
    

                                  THE COMPANY

   
    The  principal  business  of   Northwestern  Public  Service  Company   (the
"Company") is energy distribution. The Company is engaged in providing regulated
electric  and natural  gas service  in South Dakota  and natural  gas service in
Nebraska. The Company serves approximately 54,900 electric customers and  75,000
gas  customers  representing  a  diverse  mix  of  residential,  commercial  and
industrial customers. In  addition, the  Company has  investments in  nonutility
businesses  and has  recently contracted  to acquire  Synergy Group Incorporated
("Synergy"), a  major  propane  distribution  company.  See  "The  Company"  and
"Pending   Acquisition  of  Synergy  Group  Incorporated"  in  the  accompanying
Prospectus.
    

   
    The  Company's  electric  business  generates,  transmits  and   distributes
electricity to over 100 communities in eastern South Dakota. In 1994, 46% of the
Company's  total operating  revenues were from  the sale of  electric energy. At
December  31,  1994,  the  aggregate  capacity  of  all  Company-owned  electric
generating  units was  309,000 kilowatts ("kw"),  consisting of  202,000 kw from
jointly-owned baseload plants  and 107,000 kw  from internal combustion  turbine
and  diesel  units used  primarily for  peaking purposes.  All of  the Company's
baseload plants  are fueled  by  coal. The  Company has  maintained  competitive
electric  rates when  compared to  neighboring utilities  and has  a competitive
electric baseload  generating production  cost, which  includes fuel  and  plant
operating expenses, of less than 1.5 CENTS per kilowatt hour.
    

   
    The  Company's natural  gas business  purchases, transports  and distributes
natural gas to over 50 communities in eastern South Dakota and 4 communities  in
central  Nebraska. In 1994,  40% of the Company's  total operating revenues were
from the sale of natural gas. The Company purchases gas supply from more than 20
domestic and Canadian suppliers and  transports natural gas supply through  five
pipelines.  Gas  agreements provide  for firm  deliverable pipeline  capacity of
approximately 98,900  million  british  thermal  units  ("MMBTU")  per  day.  To
supplement  firm gas supplies,  the Company owns six  propane-air plants and has
contracts for underground natural gas storage services. Over the last five years
the Company  has  expanded its  gas  distribution  operations to  serve  29  new
communities in South Dakota.
    

    The Company's business strategy is summarized by three primary objectives:

   
    - To  enhance the Company's competitive  position in its energy distribution
      businesses;
    

   
    - To  expand  energy  sales  and  markets  with  value-added  services   for
      customers; and
    

   
    - To  provide earnings and  dividend growth and  increased shareholder value
      through its energy distribution businesses and investment and  acquisition
      activities.
    

   
By  enhancing the competitive position of its core electric and gas distribution
businesses and expanding its energy sales  and markets, the Company believes  it
will  position itself to be successful  in the increasingly competitive electric
and gas  distribution businesses  anticipated over  the next  several years.  To
supplement  growth strategies  in its electric  and natural  gas businesses, the
Company also plans  to seek  new investment and  acquisition opportunities  that
have  demonstrable growth potential.  The primary focus  of these investment and
acquisition activities  is  targeted  in  energy  distribution  businesses.  The
Company  also  plans  to  pursue  opportunities  in  non-energy  businesses that
complement its  existing  operations  and  provide  the  capability  to  enhance
shareholder value.
    

   
    In  May 1995,  the Company contracted  to acquire Synergy,  a retail propane
distributor serving over 200,000  customers from 152 locations  in 23 states  in
the  eastern and south central  regions of the U.S.  See "Pending Acquisition of
Synergy   Group    Incorporated"   in    the   accompanying    Prospectus.    In
    

                                      S-4

   
accordance  with  its  strategic plan,  the  Company believes  that  the Synergy
propane distribution operations are complementary to the Company's electric  and
natural  gas businesses.  Propane is the  nation's fourth  largest energy source
after electricity, natural gas  and fuel oil. The  acquisition price to be  paid
for  Synergy is $137.5 million cash (subject to certain adjustments) and certain
securities of the Company's acquisition subsidiary. The Company has entered into
an agreement with a third party for the sale of certain Synergy properties which
will reduce the  cash portion  of the  acquisition price  to approximately  $100
million.  The  Company  has  executed a  management  agreement  with  Empire Gas
Corporation ("Empire Gas") for the joint management of the properties after  the
acquisition.  Empire  Gas  is  the  nation's  eleventh  largest  retail  propane
distributor. Subsequent to the  acquisition and expected  third party sale,  the
Company's  total  assets  will consist  of  approximately 65%  electric  and gas
distribution, 25% propane distribution and  10% marketable securities and  other
diversified investments.
    

   
    The  Company's principal  executive offices are  located at  33 Third Street
S.E., Huron,  South  Dakota  57350.  The Company's  telephone  number  is  (605)
352-8411.

accompanying Prospectus and should particularly consider the following matters.

RANKING OF SUBORDINATE OBLIGATIONS UNDER THE GUARANTEE AND SUBORDINATED DEBT
SECURITIES

   
    The  Company's obligations under the Guarantee are subordinate and junior in
right of payment to all other liabilities of the Company and pari passu with the
most senior  preferred  stock issued  from  time to  time  by the  Company.  The
obligations   of  the  Company  under   the  Subordinated  Debt  Securities  are
subordinate and junior  in right  of payment to  all present  and future  Senior
Indebtedness  of the Company and pari passu with obligations to or rights of the
Company's other  general  unsecured creditors.  As  of March  31,  1995,  Senior
Indebtedness  aggregated approximately $124  million. There are  no terms in the
Preferred Securities, the  Subordinated Debt  Securities or  the Guarantee  that
limit   the  Company's  ability  to  incur  additional  indebtedness,  including
indebtedness that  ranks senior  to  the Subordinated  Debt Securities  and  the
Guarantee.  See "Description of the Guarantees  -- Status of the Guarantees" and
"Description of  the  Subordinated  Debt Securities  --  Subordination"  in  the
accompanying Prospectus, and "Description of the Subordinated Debt Securities --
Subordination" herein.
    

RIGHTS UNDER THE GUARANTEE

   
    The  Guarantee will be  qualified as an indenture  under the Trust Indenture
Act of 1939, as  amended (the "Trust Indenture  Act"). Wilmington Trust  Company
will act as indenture trustee under the Guarantee for the purposes of compliance
with  the Trust Indenture  Act (the "Guarantee  Trustee"). The Guarantee Trustee
will hold  the  Guarantee  for the  benefit  of  the holders  of  the  Preferred
Securities.
    

   
    The  Guarantee guarantees  to the  holders of  the Preferred  Securities the
payment of (i) any accrued and unpaid distributions that are required to be paid
on the Preferred Securities,  to the extent  the Company has  made a payment  of
interest  or principal on the Subordinated  Debt Securities, (ii) the Redemption
Price, including all accrued and unpaid distributions with respect to  Preferred
Securities  called for redemption by NWPS Capital, to the extent the Company has
made a payment of interest or principal on the Subordinated Debt Securities, and
(iii) upon a voluntary or involuntary dissolution, winding-up or termination  of
NWPS  Capital (other  than in connection  with the  distribution of Subordinated
Debt Securities to the holders of Preferred Securities or redemption of all  the
Preferred  Securities upon the  maturity or redemption  of the Subordinated Debt
Securities), the lesser of (a) the  aggregate of the liquidation amount and  all
accrued  and unpaid distributions on the Preferred Securities to the date of the
payment to the extent NWPS Capital has funds legally available therefor and  (b)
the  amount of  assets of NWPS  Capital remaining available  for distribution to
holders of the Preferred Securities in liquidation of NWPS Capital. The  holders
of  a majority in liquidation amount of  the Preferred Securities have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Guarantee  Trustee or to  direct the exercise  of any trust  or
power conferred upon the Guarantee Trustee under the Guarantee. If the Guarantee
Trustee  fails to enforce the Guarantee, any holder of Preferred Securities may,
after such holder's  written request  to the  Guarantee Trustee  to enforce  the
Guarantee,  institute a legal proceeding directly against the Company to enforce
the Guarantee Trustee's rights under  the Guarantee without first instituting  a
legal proceeding against NWPS Capital, the Guarantee Trustee or any other person
or  entity. If  the Company  were to  default on  its obligation  to pay amounts
payable on the Subordinated Debt  Securities, NWPS Capital would lack  available
funds    for   the   payment   of    distributions   or   amounts   payable   on
    

                                      S-7

   
redemption of the Preferred Securities or otherwise, and, in such event, holders
of the Preferred Securities  would not be  able to rely  upon the Guarantee  for
payment  of such amounts. Instead, holders  of the Preferred Securities would be
required to rely on  the enforcement by  the Property Trustee  of its rights  as
registered  holder  of  the  Subordinated Debt  Securities  against  the Company
pursuant to the terms of the Subordinated  Debt Securities and may also vote  to
appoint  a Special Regular  Trustee who shall  have the same  rights, powers and
privileges as  the Regular  Trustees. See  "Description of  the Guarantees"  and
"Description   of  the   Subordinated  Debt  Securities"   in  the  accompanying
Prospectus. The Declaration provides that  each holder of Preferred  Securities,
by  acceptance thereof, agrees to the provisions of the Guarantee, including the
subordination  provisions  thereof,   and  the   Subordinated  Debt   Securities
Indenture.
    

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES

   
    If  (i) NWPS  Capital fails  to pay distributions  in full  on the Preferred
Securities  for  six  consecutive  quarterly  distribution  periods  or  (ii)  a
Declaration  Event of Default (as defined herein) occurs and is continuing, then
the holders of  Preferred Securities  would be  entitled, by  majority vote,  to
appoint  a Special Regular Trustee,  who shall have the  same rights, powers and
privileges as the other Regular Trustees. In addition, the holders of a majority
in aggregate liquidation amount of the Preferred Securities will have the  right
to:  (i) direct the time, method, and place of conducting any proceeding for any
remedy available to the Property Trustee or to direct the exercise of any  trust
or  power conferred upon the Property  Trustee under the Declaration; (ii) waive
any past default; or (iii) exercise any right to rescind or annul a  declaration
that  the principal  of all  the Subordinated Debt  Securities shall  be due and
payable; provided, however, that  where a consent  under the Indenture  requires
the consent of all holders of the Subordinated Debt Securities affected thereby,
the  Property Trustee may only give such consent at the direction of all holders
of the Preferred Securities. If the Property Trustee fails to enforce its rights
under the Subordinated Debt Securities, to the fullest extent permitted by  law,
a holder of Preferred Securities may, after such holder's written request to the
Property  Trustee to enforce such rights,  institute a legal proceeding directly
against  the  Company  to  enforce  the  Property  Trustee's  rights  under  the
Subordinated  Debt  Securities without  first  instituting any  legal proceeding
against the  Property Trustee  or any  other person  or entity.  If the  Company
exercises  its  right to  defer payments  of interest  on the  Subordinated Debt
Securities (See "Option to Extend  Interest Payment Period" below),  appointment
of  a Special  Regular Trustee  would be the  only right  of the  holders of the
Preferred Securities if NWPS Capital fails  to pay distributions in full on  the
Preferred  Securities  for  six  consecutive quarters  until  expiration  of the
extended interest payment period (20 consecutive quarters).
    

OPTION TO EXTEND INTEREST PAYMENT PERIOD

   
    The Company has the right  under the Indenture (as  such term is defined  in
"Description  of  Subordinated Debt  Securities" herein),  to defer  payments of
interest on the Subordinated Debt  Securities by extending the interest  payment
period  at any time, and from time to time, on the Subordinated Debt Securities.
As a consequence of such an extension, quarterly distributions on the  Preferred
Securities would be deferred (but despite such deferral would continue to accrue
with  interest thereon  compounded quarterly)  by NWPS  Capital during  any such
extended interest  payment period.  Such right  to extend  the interest  payment
period for the Subordinated Debt Securities is limited to a period not exceeding
20  consecutive quarters  (each, an "Extension  Period"). In the  event that the
Company exercises  this  right to  defer  interest payments,  then  during  such
Extension  Period (a) the Company shall not declare or pay dividends on, or make
a distribution  with respect  to, or  redeem,  purchase or  acquire, or  make  a
liquidation  payment  with respect  to, any  of  its capital  stock and  (b) the
Company shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or  redeem any debt securities  issued by the Company  that
rank  pari passu with  or junior to the  Subordinated Debt Securities; provided,
however, that restriction (a) above does  not apply to any stock dividends  paid
by  the Company where the dividend stock is  the same stock as that on which the
dividend is being paid. Prior to  the termination of any such Extension  Period,
the  Company may further extend the interest payment period; provided that, such
Extension Period, together with all
    

                                      S-8

such previous  and further  extensions thereof,  may not  exceed 20  consecutive
quarters.  Upon the termination of  any Extension Period and  the payment of all
amounts then due, the  Company may commence a  new Extension Period, subject  to
the  above  requirements.  See  "Description  of  the  Preferred  Securities  --
Distributions" and "Description of the Subordinated Debt Securities -- Option to
Extend Interest Payment Period."

   
    Should the  Company exercise  its right  to defer  payments of  interest  by
extending  the interest payment period, each holder of Preferred Securities will
continue to accrue interest  income (as original issue  discount) in respect  of
the  deferred interest allocable  to its Preferred  Securities for United States
federal income tax  purposes, which  will be  allocated but  not distributed  to
holders  of record  of Preferred  Securities. As a  result, each  such holder of
Preferred Securities will recognize income for United States federal income  tax
purposes  in advance of the  receipt of cash and will  not receive the cash from
NWPS Capital related  to such income  if such holder  disposes of its  Preferred
Securities  prior to the record date for the date on which distributions of such
amounts are made. The Company has  no current intention of exercising its  right
to  defer payments of interest  by extending the interest  payment period on the
Subordinated Debt Securities. However, should the Company determine to  exercise
such right in the future, the market price of the Preferred Securities is likely
to  be affected. A  holder that disposes  of its Preferred  Securities during an
Extension Period, therefore, may not receive  the same return on its  investment
as  a holder that continues to hold  its Preferred Securities. In addition, as a
result of the Company's  right to defer interest  payments, the market price  of
the  Preferred Securities (which  represent an undivided  beneficial interest in
the Subordinated Debt Securities) may be more volatile than other securities  on
which  original issue  discount accrues  but with respect  to which  there is no
right to defer interest payments. See "United States Federal Income Taxation  --
Original Issue Discount."
    

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

    Upon  the occurrence  of a Special  Event (as defined  herein), NWPS Capital
shall be dissolved, except in the limited circumstance described below, with the
result that the Subordinated Debt Securities will be distributed to the  holders
of  the Trust Securities in connection with  the liquidation of NWPS Capital. In
certain  circumstances,  the  Company  shall  have  the  right  to  redeem   the
Subordinated  Debt Securities, in whole or in part, in lieu of a distribution of
the Subordinated Debt Securities  by NWPS Capital, in  which event NWPS  Capital
will  redeem the Trust Securities on a pro  rata basis to the same extent as the
Subordinated Debt Securities are  redeemed by the  Company. See "Description  of
the Preferred Securities -- Special Event Redemption or Distribution."

    Under  current  United  States federal  income  tax law,  a  distribution of
Subordinated Debt Securities upon the dissolution of NWPS Capital would not be a
taxable event to holders of the  Preferred Securities. Upon occurrence of a  Tax
Event  (as  defined herein),  however, a  dissolution of  NWPS Capital  in which
holders of the  Preferred Securities receive  cash would be  a taxable event  to
such  holders.  See  "United  States  Federal  Income  Taxation  --  Receipt  of
Subordinated Debt Securities or Cash Upon Liquidation of NWPS Capital."

    There can  be  no  assurance as  to  the  market prices  for  the  Preferred
Securities  or  the  Subordinated Debt  Securities  that may  be  distributed in
exchange for  Preferred  Securities if  a  dissolution or  liquidation  of  NWPS
Capital  were to occur.  Accordingly, the Preferred  Securities that an investor
may purchase, whether  pursuant to  the offer made  hereby or  in the  secondary
market,  or  the  Subordinated  Debt  Securities  that  a  holder  of  Preferred
Securities may receive on dissolution and liquidation of NWPS Capital, may trade
at a discount  to the price  that the  investor paid to  purchase the  Preferred
Securities  offered hereby. Because holders  of Preferred Securities may receive
Subordinated Debt Securities upon the occurrence of a Special Event, prospective
purchasers of Preferred Securities are  also making an investment decision  with
regard  to the Subordinated Debt Securities  and should carefully review all the
information regarding the Subordinated Debt  Securities contained herein and  in
the  accompanying Prospectus.  See "Description  of the  Preferred Securities --
Special Event Redemption or Distribution"  and "Description of the  Subordinated
Debt Securities -- General."

                                      S-9

LIMITED VOTING RIGHTS

    Holders  of Preferred Securities will have limited voting rights and, except
for the rights of holders of  Preferred Securities to appoint a Special  Regular
Trustee  upon the  occurrence of  certain events  described herein,  will not be
entitled to vote to appoint, remove or  replace, or to increase or decrease  the
number  of, NWPS  Trustees, which  voting rights  are vested  exclusively in the
holder of the Common Securities.

TRADING PRICE

    The Preferred Securities may  trade at a price  that does not fully  reflect
the  value  of  accrued  but  unpaid interest  with  respect  to  the underlying
Subordinated Debt Securities. A holder who disposes of his Preferred  Securities
between  record dates for payments of  distributions thereon will be required to
include accrued but unpaid interest on the Subordinated Debt Securities  through
the  date of disposition  in income as  ordinary income (i.e.,  OID), and to add
such amount to his adjusted  tax basis in his pro  rata share of the  underlying
Subordinated Debt Securities deemed disposed of. To the extent the selling price
is less than the holder's adjusted tax basis (which will include, in the form of
OID,  all accrued but unpaid interest), a  holder will recognize a capital loss.
Subject to  certain limited  exceptions,  capital losses  cannot be  applied  to
offset  ordinary  income  for United  States  federal income  tax  purposes. See
"United States Federal Income Taxation -- Original Issue Discount" and "Sales of
Preferred Securities."

                            NWPS CAPITAL FINANCING I

   
    NWPS Capital  is  a  statutory  business trust  formed  under  Delaware  law
pursuant  to (i) a declaration of trust, dated  as of June 19, 1995, executed by
the Company, as sponsor (the "Sponsor"),  and the trustees of NWPS Capital  (the
"NWPS  Trustees")  and  (ii) the  filing  of  a certificate  of  trust  with the
Secretary of State of the  State of Delaware on  June 19, 1995. The  declaration
will  be amended and restated  in its entirety (as  so amended and restated, the
"Declaration") substantially in the form filed as an exhibit to the Registration
Statement of which  this Prospectus Supplement  and the accompanying  Prospectus
form  a part. The Declaration will be  qualified as an indenture under the Trust
Indenture Act. Upon issuance of the Preferred Securities, the purchasers thereof
will own all  of the  Preferred Securities.  See "Description  of the  Preferred
Securities  -- Book-Entry  Only Issuance --  The Depository  Trust Company." The
Company will directly or  indirectly acquire Common  Securities in an  aggregate
liquidation  amount  equal to  3% of  the  total capital  of NWPS  Capital. NWPS
Capital exists for the  exclusive purposes of (i)  issuing the Trust  Securities
representing  undivided beneficial  interests in the  assets of  the Trust, (ii)
investing the gross proceeds  of the Trust Securities  in the Subordinated  Debt
Securities  and  (iii)  engaging in  only  those other  activities  necessary or
incidental thereto.
    

   
    Pursuant to the Declaration, the number  of NWPS Trustees will initially  be
three. Two of the NWPS Trustees (the "Regular Trustees") will be persons who are
employees  or officers  of or  who are  affiliated with  the Company.  The third
trustee will be a  financial institution that maintains  its principal place  of
business  in the State of  Delaware and is unaffiliated  with the Company, which
trustee will serve as  property trustee under the  Declaration and as  indenture
trustee  for the purposes  of the Trust Indenture  Act (the "Property Trustee").
Initially, Wilmington Trust Company, a Delaware banking corporation, will be the
Property Trustee  unless  removed  or  replaced by  the  holder  of  the  Common
Securities.  Wilmington Trust Company  will also act  as indenture trustee under
the Guarantee (the "Guarantee Trustee"). See "Description of the Guarantees"  in
the accompanying Prospectus. In certain circumstances, the holders of a majority
in  aggregate liquidation amount of the Preferred Securities will be entitled to
appoint one Regular Trustee  (a "Special Regular Trustee"),  who need not be  an
officer   or  employee  of  or  otherwise   affiliated  with  the  Company.  See
"Description of the Preferred Securities -- Voting Rights."
    

    The Property Trustee will hold title to the Subordinated Debt Securities for
the benefit of  the holders of  the Trust Securities,  and the Property  Trustee
will have the power to exercise all rights,

                                      S-10

powers,  and privileges under the Indenture (as defined herein) as the holder of
the Subordinated  Debt  Securities.  In  addition,  the  Property  Trustee  will
maintain  exclusive control  of a  segregated non-interest  bearing bank account
(the  "Property  Account")  to  hold  all  payments  made  in  respect  of   the
Subordinated  Debt  Securities  for the  benefit  of  the holders  of  the Trust
Securities. The  Property  Trustee  will  make  payments  of  distributions  and
payments  on liquidation, redemption  and otherwise to the  holders of the Trust
Securities out of funds  from the Property Account.  The Guarantee Trustee  will
hold  the Guarantee for the benefit of  the holders of the Preferred Securities.
Subject to the right  of the holders  of the Preferred  Securities to appoint  a
Special  Regular Trustee, the Company,  as the direct or  indirect holder of all
the Common Securities,  will have the  right to appoint,  remove or replace  any
NWPS  Trustee and to increase or decrease  the number of NWPS Trustees; provided
that, (i)  the number  of NWPS  Trustees  shall be  at least  three and  (ii)  a
majority  shall be Regular Trustees. The Company  will pay all fees and expenses
related  to  NWPS  Capital  and  the  offering  of  the  Trust  Securities.  See
"Description of the Subordinated Debt Securities -- Miscellaneous."

    The  rights of the  holders of the  Preferred Securities, including economic
rights,  rights  to  information  and  voting  rights,  are  set  forth  in  the
Declaration,  the Delaware Business Trust Act (the "Business Trust Act") and the
Trust Indenture Act. See "Description of the Preferred Securities."

   
                                USE OF PROCEEDS
    

   
    The  net  proceeds  from  the  sale  of  approximately  1,000,000  Preferred
Securities  (approximately $24,212,000) will be  applied to fund the acquisition
of Synergy, including certain transaction expenses. The additional net  proceeds
from  the sale of the  Preferred Securities will be  applied to repay short-term
debt of the Company. See "Use of Proceeds" in the accompanying Prospectus.
    

                              ACCOUNTING TREATMENT

   
    The financial statements of NWPS Capital will be reflected in the  Company's
consolidated  financial  statements  with  the  Preferred  Securities  shown  as
Company-Obligated Mandatorily  Redeemable  Preferred  Securities  of  Subsidiary
Trust.  All of the assets  of NWPS Capital will  be approximately $31 million of
Subordinated Debt Securities of the Company  which will bear interest at a  rate
of     % per annum, assuming the issuance of 1.2 million Preferred Securities.
    

                    DESCRIPTION OF THE PREFERRED SECURITIES

    The  Preferred  Securities  will be  issued  pursuant  to the  terms  of the
Declaration. The Declaration will be qualified  as an indenture under the  Trust
Indenture  Act. The Property Trustee, the  Wilmington Trust Company, will act as
the indenture trustee  for purposes  of compliance  with the  provisions of  the
Trust  Indenture Act. The  terms of the Preferred  Securities will include those
stated in the Declaration,  the Business Trust  Act and those  made part of  the
Declaration  by the Trust Indenture Act.  The following summary of the principal
terms and provisions of the Preferred Securities does not purport to be complete
and is  subject  to,  and  qualified  in  its  entirety  by  reference  to,  the
Declaration,  a  copy  of which  is  filed  as an  exhibit  to  the Registration
Statement of which this Prospectus Supplement is a part, the Business Trust  Act
and the Trust Indenture Act.

GENERAL

    The  Declaration authorizes the Regular Trustees  to issue on behalf of NWPS
Capital the Trust Securities, which represent undivided beneficial interests  in
the assets of NWPS Capital. All of the Common Securities will be owned, directly
or  indirectly,  by the  Company.  The Common  Securities  rank pari  passu, and
payments will  be  made  thereon  on  a  pro  rata  basis,  with  the  Preferred
Securities,  except that upon the occurrence  of a Declaration Event of Default,
the rights  of  the holders  of  the Common  Securities  to receive  payment  of
periodic  distributions and payments upon  liquidation, redemption and otherwise
will be subordinated to the rights  of the holders of the Preferred  Securities.
The  Declaration does not permit the issuance  by NWPS Capital of any securities
other than the Trust  Securities or the incurrence  of any indebtedness by  NWPS
Capital. Pursuant to the Declaration, the

                                      S-11

Property  Trustee will  own the Subordinated  Debt Securities  purchased by NWPS
Capital for the benefit of the holders  of the Trust Securities. The payment  of
distributions out of money held by NWPS Capital, and payments upon redemption of
the  Preferred Securities or liquidation of  NWPS Capital, are guaranteed by the
Company to the  extent described under  "Description of the  Guarantees" in  the
accompanying Prospectus. The Guarantee will be held by Wilmington Trust Company,
the  Guarantee  Trustee,  for  the  benefit  of  the  holders  of  the Preferred
Securities. The  Guarantee does  not cover  payment of  distributions when  NWPS
Capital  does not have sufficient available  funds to pay such distributions. In
such event, the remedy of a holder of Preferred Securities is to vote to appoint
a Special Regular  Trustee and  to direct the  Property Trustee  to enforce  the
Property   Trustee's  rights   under  the  Subordinated   Debt  Securities.  See
"Description of the Preferred Securities -- Voting Rights."

DISTRIBUTIONS

    Distributions on the Preferred Securities will be fixed at a rate per  annum
of      %  of the  stated  liquidation  amount of  $25  per  Preferred Security.
Distributions in arrears for more than one quarter will bear interest thereon at
the rate per annum of   % thereof, compounded quarterly. The term "distribution"
as used herein includes any such  interest payable unless otherwise stated.  The
amount  of distributions payable for any period will be computed on the basis of
a 360-day year of twelve 30-day months.

   
    Distributions on the  Preferred Securities will  be cumulative, will  accrue
from           , 1995, the date of initial issuance thereof, and will be payable
quarterly  in arrears on March 31, June 30, September 30 and December 31 of each
year, commencing            , 1995, when, as and if available and determined  to
be so payable by the Property Trustee, except as otherwise described below.
    

   
    The  Company has the right under the Indenture to defer payments of interest
on the Subordinated  Debt Securities  by extending the  interest payment  period
from  time  to  time  on  the  Subordinated  Debt  Securities,  which  right, if
exercised, would defer quarterly distributions on the Preferred Securities  (but
such  distributions would continue to accrue  with interest since interest would
continue to  accrue  on  the  Subordinated  Debt  Securities)  during  any  such
Extension  Period.  Such right  to extend  the interest  payment period  for the
Subordinated Debt Securities is limited to a period not exceeding 20 consecutive
quarters. In the event that the  Company exercises this right, then during  such
Extension  Period (a) the  Company shall not  declare or pay  dividends on, make
distributions with  respect  to, or  redeem,  purchase  or acquire,  or  make  a
liquidation  payment  with respect  to, any  of  its capital  stock and  (b) the
Company shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or  redeem any debt securities  issued by the Company  that
rank  pari passu with or junior  to such Subordinated Debt Securities; provided,
however, that,  the  foregoing restriction  (a)  does  not apply  to  any  stock
dividends paid by the Company where the dividend stock is the same stock as that
on  which  the dividend  is being  paid. Prior  to the  termination of  any such
Extension Period, the Company  may further extend  the interest payment  period;
provided  that,  such  Extension Period,  together  with all  such  previous and
further extensions thereof,  may not  exceed 20 consecutive  quarters or  extend
beyond the maturity of the Subordinated Debt Securities. Upon the termination of
any  Extension Period and the  payment of all amounts  then due, the Company may
select  a  new  Extension  Period,  subject  to  the  above  requirements.   See
"Description  of the Subordinated Debt Securities -- Interest" and "-- Option to
Extend Interest Payment  Period." If  distributions are  deferred, the  deferred
distributions and accrued interest thereon shall be paid to holders of record of
the Preferred Securities as they appear on the books and records of NWPS Capital
on the record date next following the termination of such deferral period.
    

    Distributions  on the Preferred Securities must be paid on the dates payable
to the extent that NWPS Capital has  funds legally available for the payment  of
such  distributions in the Property Account.  NWPS Capital's funds available for
distribution to  the holders  of the  Preferred Securities  will be  limited  to
payments  received from  the Company  on the  Subordinated Debt  Securities. See

                                      S-12

"Description of the Subordinated Debt Securities." The payment of  distributions
out  of moneys held by  NWPS Capital is guaranteed by  the Company to the extent
set forth under "Description of the Guarantees" in the accompanying Prospectus.

    Distributions on the  Preferred Securities  will be payable  to the  holders
thereof  as they appear on the books and records of NWPS Capital on the relevant
record dates, which, as  long as the Preferred  Securities remain in  book-entry
only  form, will be one  Business Day prior to  the relevant payment dates. Such
distributions will be paid  through the Property Trustee  who will hold  amounts
received  in respect of the Subordinated Debt Securities in the Property Account
for the  benefit  of  the  holders  of the  Trust  Securities.  Subject  to  any
applicable laws and regulations and the provisions of the Declaration, each such
payment  will  be  made as  described  under  "Book-Entry Only  Issuance  -- The
Depository Trust Company" below. In the  event that the Preferred Securities  do
not  continue to remain in book-entry only form, the Regular Trustees shall have
the right to select relevant record dates, which shall be more than one Business
Day prior to the  relevant payment dates.  In the event that  any date on  which
distributions  are to be made on the Preferred Securities is not a Business Day,
then payment of the distributions payable on such date will be made on the  next
succeeding  day  which is  a Business  Day  (and without  any interest  or other
payment in respect of any such delay),  except that, if such Business Day is  in
the next succeeding calendar year, such payment shall be made on the immediately
preceding  Business Day, in each case with the  same force and effect as if made
on such payment date. A "Business Day"  shall mean any day other than  Saturday,
Sunday  or any other day  on which banking institutions in  the City of New York
(in the state of New  York) are permitted or required  by any applicable law  to
close.

MANDATORY REDEMPTION

   
    The  Subordinated Debt Securities will mature on          , 2025, unless the
maturity date  is  extended at  the  option  of the  Company  (provided  certain
conditions are met), and may be redeemed, in whole or in part, at any time on or
after              ,  2000, or  at any  time in  certain circumstances  upon the
occurrence of  a  Tax  Event.  Upon  the  repayment  of  the  Subordinated  Debt
Securities,  whether  at maturity  or upon  redemption,  the proceeds  from such
repayment or payment shall simultaneously be applied to redeem Trust  Securities
having  an aggregate liquidation amount equal  to the aggregate principal amount
of the Subordinated  Debt Securities  so repaid  or redeemed  at the  Redemption
Price;  provided that, holders of Trust Securities  shall be given not less than
30 nor more  than 60 days  notice of  such redemption. See  "Description of  the
Subordinated  Debt Securities --  Optional Redemption." In  the event that fewer
than all  of  the outstanding  Preferred  Securities  are to  be  redeemed,  the
Preferred  Securities will be  redeemed pro rata  as described under "Book-Entry
Only Issuance -- the Depository Trust Company" below.
    

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

   
    "Tax Event" means that the Regular  Trustees shall have received an  opinion
of  nationally recognized independent tax counsel experienced in such matters (a
"Dissolution Tax Opinion") to the effect that, as a result of (a) any  amendment
to,  or change (including any announced prospective change) in, the laws (or any
regulations thereunder) of  the United  States or any  political subdivision  or
taxing  authority  thereof or  therein, (b)  any  amendment to  or change  in an
interpretation or application  of such  laws or regulations  by any  legislative
body,   court,  governmental  agency  or  regulatory  authority  (including  the
enactment of any  legislation and the  publication of any  judicial decision  or
regulatory  determination on or after the date  of the issuance of the Preferred
Securities), (c)  any  interpretation  or  pronouncement  that  provides  for  a
position  with  respect  to  such  laws or  regulations  that  differs  from the
theretofore generally  accepted  position,  or  (d)  any  action  taken  by  any
governmental  agency  or  regulatory  authority, which  amendment  or  change is
enacted, promulgated or effective, or  which interpretation or pronouncement  is
issued or announced, or which action is taken, in each case on or after the date
of the issuance of the Preferred Securities, there is more than an insubstantial
risk that (i) NWPS Capital is, or will be within 90 days after the date thereof,
subject  to United States federal  income tax with respect  to income accrued or
received on  the Subordinated  Debt Securities,  (ii) interest  payable to  NWPS
Capital    on   the   Subordinated    Debt   Securities   is    not,   or   will
    

                                      S-13

   
not be within 90 days after the date thereof, in whole or in part, deductible by
the Company for United States federal income tax purposes or (iii) NWPS  Capital
is or will be subject to more than a de minimis amount of other taxes, duties or
other governmental charges.
    

   
    "Investment  Company  Event"  means  that the  Regular  Trustees  shall have
received an opinion of nationally recognized independent counsel experienced  in
practice  under the Investment Company Act of 1940, as amended (the "1940 Act"),
that as a  result of  the occurrence of  a change  in law or  regulation by  any
legislative  body, court, governmental agency or regulatory authority (a "Change
in 1940 Act Law"), the  Trust is or will  be considered an "investment  company"
which  is required to be registered under the 1940 Act, which Change in 1940 Act
Law becomes effective  on or after  the date  of the issuance  of the  Preferred
Securities.  In case of  any uncertainty regarding  an Investment Company Event,
the good faith  determination of the  Regular Trustees, based  on the advice  of
counsel, shall be conclusive.
    

    If,  at  any time,  a  Tax Event  or an  Investment  Company Event  (each, a
"Special Event") shall occur  and be continuing, NWPS  Capital shall, except  in
the  limited circumstances described  below, be dissolved  with the result that,
after satisfaction of liabilities to  creditors of the Trust, Subordinated  Debt
Securities  with an  aggregate principal  amount equal  to the  aggregate stated
liquidation amount of, with an interest rate identical to the distribution  rate
of,  and accrued and  unpaid interest equal to  accrued and unpaid distributions
on, the  Trust Securities,  would be  distributed to  the holders  of the  Trust
Securities  in liquidation of such  holders' interests in NWPS  Capital on a pro
rata basis  within 90  days  following the  occurrence  of such  Special  Event;
provided,  however, that  in the  case of  the occurrence  of a  Tax Event, such
dissolution and  distribution  shall be  conditioned  on the  Regular  Trustees'
receipt   of  an  opinion  of  nationally  recognized  independent  tax  counsel
experienced in such matters (a "No Recognition Opinion"), which opinion may rely
on published revenue rulings of the Internal Revenue Service, to the effect that
the holders of  the Trust Securities  will not  recognize any gain  or loss  for
United  States federal income tax  purposes as a result  of such dissolution and
distribution of Subordinated Debt Securities; and provided, further, that, if at
the time there is available to NWPS Capital the opportunity to eliminate, within
such 90-day period, the Special Event by taking some ministerial action, such as
filing a form or  making an election or  pursuing some other reasonable  measure
that  will have no adverse effect on NWPS Capital, the Company or the holders of
the Trust  Securities,  NWPS  Capital  will  pursue  such  measure  in  lieu  of
dissolution. Furthermore, if in the case of the occurrence of a Tax Event, after
receipt of a Dissolution Tax Opinion by the Regular Trustees (i) the Company has
received  an  opinion  (a  "Redemption Tax  Opinion")  of  nationally recognized
independent tax counsel experienced in such matters  that, as a result of a  Tax
Event,  there  is more  than an  insubstantial  risk that  the Company  would be
precluded from deducting the  interest on the  Subordinated Debt Securities  for
United  States  federal  income  tax  purposes  even  if  the  Subordinated Debt
Securities were distributed to the holders of Trust Securities in liquidation of
such holders' interests in NWPS Capital as described above, or (ii) the  Regular
Trustees  shall have been informed by such  tax counsel that it cannot deliver a
No Recognition Opinion to NWPS Capital,  the Company shall have the right,  upon
not  less than 30 nor more than 60  days notice, to redeem the Subordinated Debt
Securities, in  whole  or  in  part,  for cash  within  90  days  following  the
occurrence  of such Tax Event, and,  following such redemption, Trust Securities
with an aggregate liquidation amount equal to the aggregate principal amount  of
the  Subordinated Debt Securities so redeemed  shall be redeemed by NWPS Capital
at the Redemption Price on a pro rata basis; provided, however, that, if at  the
time  there  is available  to the  Company  or NWPS  Capital the  opportunity to
eliminate, within such 90-day period, the  Tax Event by taking some  ministerial
action,  such as  filing a  form or  making an  election or  pursuing some other
similar reasonable measure  which has  no adverse  effect on  NWPS Capital,  the
Company or the holders of the Trust Securities, the Company or NWPS Capital will
pursue such measure in lieu of redemption.

    If  the Subordinated Debt  Securities are distributed to  the holders of the
Preferred Securities,  the  Company will  use  its  best efforts  to  cause  the
Subordinated  Debt Securities to be listed on  the New York Stock Exchange or on
such other exchange as the Preferred Securities are then listed.

                                      S-14

    After the date  for any  distribution of Subordinated  Debt Securities  upon
dissolution  of NWPS  Capital, (i)  the Preferred  Securities will  no longer be
deemed to be  outstanding, (ii)  the Depositary or  its nominee,  as the  record
holder of the Preferred Securities, will receive a registered global certificate
or  certificates representing the  Subordinated Debt Securities  to be delivered
upon such  distribution,  and  (iii)  any  certificates  representing  Preferred
Securities not held by the Depositary or its nominee will be deemed to represent
Subordinated  Debt Securities having an aggregate  principal amount equal to the
aggregate stated liquidation amount of, with  an interest rate identical to  the
distribution  rate  of, and  accrued and  unpaid interest  equal to  accrued and
unpaid distributions on  such Preferred Securities  until such certificates  are
presented to the Company or its agent for transfer or reissuance.

    There  can be no assurance as to  the market prices for either the Preferred
Securities or  the  Subordinated Debt  Securities  that may  be  distributed  in
exchange  for the Preferred Securities if  a dissolution and liquidation of NWPS
Capital were to occur.  Accordingly, the Preferred  Securities that an  investor
may  purchase, whether  pursuant to  the offer made  hereby or  in the secondary
market, or the Subordinated  Debt Securities that an  investor may receive if  a
dissolution  and  liquidation of  NWPS Capital  were  to occur,  may trade  at a
discount to  the  price  that  the  investor  paid  to  purchase  the  Preferred
Securities offered hereby.

REDEMPTION PROCEDURES

    NWPS  Capital may  not redeem  fewer than  all of  the outstanding Preferred
Securities unless all  accrued and unpaid  distributions have been  paid on  all
Preferred  Securities for all  quarterly distribution periods  terminating on or
prior to the date of redemption.

    If NWPS  Capital  gives a  notice  of  redemption in  respect  of  Preferred
Securities  (which notice  will be irrevocable),  then, by 12:00  noon, New York
City time, on the redemption date, and  if the Company has paid to the  Property
Trustee a sufficient amount of cash in connection with the related redemption or
maturity of the Subordinated Debt Securities, then NWPS Capital will irrevocably
deposit  with the Depositary  funds sufficient to  pay the applicable Redemption
Price and will give the Depositary irrevocable instructions and authority to pay
the Redemption Price to the holders of the Preferred Securities. See "Book-Entry
Only Issuance -- The  Depository Trust Company." If  notice of redemption  shall
have  been given and funds deposited as required, then, immediately prior to the
close of  business on  the date  of such  deposit, distributions  will cease  to
accrue  and all  rights of  holders of such  Preferred Securities  so called for
redemption will  cease,  except the  right  of  the holders  of  such  Preferred
Securities  to  receive  the  Redemption  Price  but  without  interest  on such
Redemption Price. In the event that  any date fixed for redemption of  Preferred
Securities  is not a Business Day, then  payment of the Redemption Price payable
on such date  will be made  on the next  succeeding day that  is a Business  Day
(without  any interest or  other payment in  respect of any  such delay), except
that, if such Business Day falls in the next calendar year, such payment will be
made on the immediately preceding Business Day. In the event that payment of the
Redemption Price in respect  of Preferred Securities  is improperly withheld  or
refused  and not paid either by NWPS Capital,  or by the Company pursuant to the
Guarantee, distributions on such Preferred Securities will continue to accrue at
the then  applicable rate  from the  original  redemption date  to the  date  of
payment, in which case the actual payment date will be considered the date fixed
for redemption for purposes of calculating the Redemption Price.

    In the event that fewer than all of the outstanding Preferred Securities are
to  be redeemed, the Preferred Securities will be redeemed pro rata as described
below under "Book-Entry Only Issuance -- The Depository Trust Company."

    Subject to the foregoing and applicable law (including, without  limitation,
United  States federal securities laws), the  Company or its subsidiaries may at
any time, and from  time to time, purchase  outstanding Preferred Securities  by
tender, in the open market or by private agreement.

                                      S-15

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

    In  the  event of  any  voluntary or  involuntary  liquidation, dissolution,
winding-up or  termination of  NWPS  Capital (each  a "Liquidation"),  the  then
holders  of the  Preferred Securities  will be  entitled to  receive out  of the
assets of NWPS Capital,  after satisfaction of liabilities  to creditors of  the
Trust,  distributions  in  an  amount  equal  to  the  aggregate  of  the stated
liquidation amount  of  $25  per  Preferred Security  plus  accrued  and  unpaid
distributions  thereon to the date  of payment (the "Liquidation Distribution"),
unless, in connection with such Liquidation, Subordinated Debt Securities in  an
aggregate  stated  principal amount  equal to  the aggregate  stated liquidation
amount of, with  an interest  rate identical to  the distribution  rate of,  and
accrued  and unpaid interest  equal to accrued and  unpaid distributions on, the
Preferred Securities have been distributed on a pro rata basis to the holders of
the Preferred Securities in exchange for such Securities.

    If, upon any such Liquidation, the Liquidation Distribution can be paid only
in part because NWPS  Capital has insufficient assets  available to pay in  full
the  aggregate Liquidation  Distribution, then  the amounts  payable directly by
NWPS Capital on the Preferred Securities shall be paid on a pro rata basis.  The
holders  of the Common Securities will be entitled to receive distributions upon
any such dissolution  pro rata  with the  holders of  the Preferred  Securities,
except  that if a Declaration  Event of Default has  occurred and is continuing,
the Preferred Securities shall have a preference over the Common Securities with
regard to such distributions.

    Pursuant to the Declaration, NWPS Capital shall terminate (i) on           ,
2050, the expiration of the  term of NWPS Capital,  (ii) upon the bankruptcy  of
the  Company or the holder of the Common  Securities, (iii) upon the filing of a
certificate of dissolution or its equivalent  with respect to the holder of  the
Common  Securities or the  Company, the filing of  a certificate of cancellation
with respect to NWPS Capital, or the revocation of the charter of the holder  of
the  Common Securities or  the Company and  the expiration of  90 days after the
date of revocation without a  reinstatement thereof, (iv) upon the  distribution
of Subordinated Debt Securities upon the occurrence of a Special Event, (v) upon
the  entry of  a decree of  a judicial dissolution  of the holder  of the Common
Securities, the Company or NWPS Capital, or (vi) upon the redemption of all  the
Trust Securities.

DECLARATION EVENTS OF DEFAULT

    An  event of default  under the Indenture (an  "Indenture Event of Default")
constitutes an event of default under the Declaration with respect to the  Trust
Securities  (a "Declaration Event  of Default"), provided  that, pursuant to the
Declaration, the holder of the Common  Securities will be deemed to have  waived
any Declaration Event of Default with respect to the Common Securities until all
Declaration Events of Default with respect to the Preferred Securities have been
cured,  waived or otherwise eliminated. Until such Declaration Events of Default
with respect  to  the  Preferred  Securities have  been  so  cured,  waived,  or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf  of the holders of  the Preferred Securities and  only the holders of the
Preferred Securities will  have the right  to direct the  Property Trustee  with
respect to certain matters under the Declaration, and therefore the Indenture.

    Upon  the occurrence of a Declaration Event of Default, the Property Trustee
as the sole holder of the Subordinated Debt Securities will have the right under
the Indenture to declare the principal of and interest on the Subordinated  Debt
Securities  to be immediately due and payable.  The Company and NWPS Capital are
each  required  to  file  annually  with  the  Property  Trustee  an   officer's
certificate  as to  its compliance with  all conditions and  covenants under the
Declaration.

VOTING RIGHTS

    Except as  described  herein,  under  the  Business  Trust  Act,  the  Trust
Indenture  Act  and  under  "Description of  the  Guarantees  --  Amendments and
Assignment" in the accompanying Prospectus, and as otherwise required by law and
the Declaration, the  holders of the  Preferred Securities will  have no  voting
rights.

                                      S-16

   
    If  (i) NWPS  Capital fails  to pay distributions  in full  on the Preferred
Securities for  six (6)  consecutive quarterly  distribution periods  or (ii)  a
Declaration  Event of  Default occurs  and is  continuing (each  an "Appointment
Event"), then the holders of the Preferred Securities, acting as a single class,
will be entitled by a vote of a majority in liquidation amount of the  Preferred
Securities  to appoint a  Special Regular Trustee. If  the Company exercises its
right to defer  payments of interest  on the Subordinated  Debt Securities  (See
"Option  to Extend  Interest Payment  Period" below),  appointment of  a Special
Regular Trustee  would  be  the only  right  of  the holders  of  the  Preferred
Securities  if NWPS Capital fails to pay  distributions in full on the Preferred
Securities for  six  consecutive  quarters  until  expiration  of  the  extended
interest  payment period (20 consecutive  quarters). For purposes of determining
whether NWPS  Capital  has failed  to  pay distributions  in  full for  six  (6)
consecutive  quarterly distribution  periods, distributions  shall be  deemed to
remain in arrears, notwithstanding any  payments in respect thereof, until  full
cumulative distributions have been or contemporaneously are paid with respect to
all  quarterly  distribution periods  terminating  on or  prior  to the  date of
payment of such  cumulative distributions.  Any holder  of Preferred  Securities
(other  than the Company or any of its affiliates) shall be entitled to nominate
any person to be appointed  as Special Regular Trustee.  Not later than 30  days
after  such  right to  appoint  a Special  Regular  Trustee arises,  the Regular
Trustees shall convene a meeting of the holders of Preferred Securities for  the
purpose of appointing a Special Regular Trustee. If the Regular Trustees fail to
convene such meeting within such 30-day period, the holders of not less than 10%
of  the aggregate stated liquidation amount  of the Preferred Securities will be
entitled to convene such meeting. The provisions of the Declaration relating  to
the convening and conduct of the meetings of the holders will apply with respect
to  any such meeting. Any Special Regular Trustee so appointed shall cease to be
a Special Regular Trustee if the Appointment Event pursuant to which the Special
Regular Trustee  was appointed  and all  other Appointment  Events cease  to  be
continuing. Notwithstanding the appointment of any such Special Regular Trustee,
the  Company shall retain all rights under the Indenture, including the right to
defer payments of interest by extending the interest payment period as  provided
under  "Description  of the  Subordinated Debt  Securities  -- Option  to Extend
Interest Payment  Period."  If  such  an extension  occurs,  there  will  be  no
Indenture  Event of Default  and, consequently, no  Declaration Event of Default
for failure to make any scheduled  interest payment during the Extension  Period
on the date originally scheduled.
    

   
    Subject  to the requirement of the  Property Trustee obtaining a tax opinion
in certain circumstances set forth in  the last sentence of this paragraph,  the
holders  of  a  majority  in  aggregate  liquidation  amount  of  the  Preferred
Securities have the right to (i) direct the time, method and place of conducting
any proceeding for any remedy available  to the Property Trustee, or direct  the
exercise  of any trust  or power conferred  upon the Property  Trustee under the
Declaration including the right to direct the Property Trustee, as holder of the
Subordinated Debt  Securities,  to exercise  the  remedies available  under  the
Indenture  with respect to the Subordinated Debt Securities, (ii) waive any past
Indenture Event  of Default  that is  waivable  under Section  513 of  the  Base
Indenture (as defined herein), or (iii) exercise any right to rescind or annul a
declaration  that the principal of all the Subordinated Debt Securities shall be
due and payable; provided,  however, that, where a  consent under the  Indenture
would require the consent of all holders of the Subordinated Debt Securities, no
such  consent shall be given by the Property Trustee without the prior direction
of all holders  of the Preferred  Securities. If the  Property Trustee fails  to
enforce its rights under the Subordinated Debt Securities, to the fullest extent
permitted  by  law, a  record  holder of  Preferred  Securities may,  after such
holder's written  request  to  the  Property Trustee  to  enforce  such  rights,
institute  a  legal  proceeding  directly against  the  Company  to  enforce the
Property Trustee's rights under the  Subordinated Debt Securities without  first
instituting  any  legal proceeding  against the  Property  Trustee or  any other
person or entity. The Property Trustee shall notify all holders of the Preferred
Securities of any  notice of default  received from the  Indenture Trustee  with
respect  to the Subordinated Debt Securities.  Such notice shall state that such
Indenture Event  of Default  also constitutes  a Declaration  Event of  Default.
Except  with respect  to directing  the time, method  and place  of conducting a
proceeding for a remedy, the Property Trustee shall not take any of the  actions
described in clauses (i), (ii) or (iii)
    

                                      S-17

above  unless the Property Trustee has obtained an opinion of tax counsel to the
effect that,  as a  result of  such action,  NWPS Capital  will not  fail to  be
classified as a grantor trust for United States federal income tax purposes.

   
    In  the event  the consent  of the  Property Trustee,  as the  holder of the
Subordinated Debt Securities, is  required under the  Indenture with respect  to
any  amendment, modification or termination of the Indenture or the Subordinated
Debt Securities, the Property Trustee shall request the direction of the holders
of the  Trust  Securities  with  respect  to  such  amendment,  modification  or
termination  and  shall vote  with respect  to  such amendment,  modification or
termination as  directed  by a  majority  in  liquidation amount  of  the  Trust
Securities  voting together as  a single class; provided,  however, that where a
consent under the  Indenture would  require the consent  of all  holders of  the
Subordinated Debt Securities, the Property Trustee may only give such consent at
the direction of all holders of the Trust Securities. The Property Trustee shall
be under no obligation to take any such action in accordance with the directions
of  the holders of the Trust Securities unless the Property Trustee has obtained
an opinion of tax counsel to the  effect that for the purposes of United  States
federal  income tax NWPS Capital will not  be classified as other than a grantor
trust.
    

    A waiver of an Indenture  Event of Default will  constitute a waiver of  the
corresponding Declaration Event of Default.

    Any required approval or direction of holders of Preferred Securities may be
given at a separate meeting of holders of Preferred Securities convened for such
purpose,  at a meeting of all of the  holders of Trust Securities or pursuant to
written consent. The  Regular Trustees  will cause a  notice of  any meeting  at
which  holders of Preferred  Securities are entitled  to vote, or  of any matter
upon which action  by written  consent of  such holders is  to be  taken, to  be
mailed  to each holder of record of  Preferred Securities. Each such notice will
include a statement  setting forth the  following information: (i)  the date  of
such meeting or the date by which such action is to be taken; (ii) a description
of  any resolution proposed for  adoption at such meeting  on which such holders
are entitled to vote or of such matter upon which written consent is sought; and
(iii) instructions for the delivery of  proxies or consents. No vote or  consent
of  the holders  of Preferred  Securities will be  required for  NWPS Capital to
redeem  and  cancel  Preferred   Securities  or  distribute  Subordinated   Debt
Securities in accordance with the Declaration.

    Notwithstanding that holders of Preferred Securities are entitled to vote or
consent  under any  of the circumstances  described above, any  of the Preferred
Securities that are owned at such time by the Company or any entity directly  or
indirectly  controlling or  controlled by,  or under  direct or  indirect common
control with, the Company, shall not be  entitled to vote or consent and  shall,
for purposes of such vote or consent, be treated as if such Preferred Securities
were not outstanding.

    The  procedures by which holders of  Preferred Securities may exercise their
voting rights  are described  below. See  "-- Book-Entry  Only Issuance  --  The
Depository Trust Company" below.

    Except  in the limited circumstances described above, in connection with the
appointment of a Special  Regular Trustee, holders  of the Preferred  Securities
will  have  no  rights  to appoint  or  remove  the NWPS  Trustees,  who  may be
appointed, removed or replaced solely by  the Company as the indirect or  direct
holder of all of the Common Securities.

MODIFICATION OF THE DECLARATION

    The Declaration may be modified and amended if approved by a majority of the
Regular  Trustees (and in certain  circumstances the Property Trustee), provided
that, if any proposed amendment provides for, or the Regular Trustees  otherwise
propose  to effect,  (i) any action  that would materially  adversely affect the
powers, preferences or special rights of the Trust Securities, whether by way of
amendment to the Declaration or  otherwise, or (ii) the dissolution,  winding-up
or  termination  of  NWPS  Capital  other than  pursuant  to  the  terms  of the
Declaration, then  the holders  of the  Trust Securities  voting together  as  a
single  class will be  entitled to vote  on such amendment  or proposal and such
amendment or proposal  shall not  be effective except  with the  approval of  at
least 66 2/3% in

                                      S-18

liquidation  amount of the Trust Securities affected thereby; provided that, the
rights of holders of Preferred Securities  to appoint a Special Regular  Trustee
shall not be amended without the consent of each holder of Preferred Securities;
provided  further that, if any  amendment or proposal referred  to in clause (i)
above would materially  adversely affect  only the Preferred  Securities or  the
Common Securities, then only the affected class will be entitled to vote on such
amendment  or proposal  and such  amendment or  proposal shall  not be effective
except with the  approval of  66 2/3%  in liquidation  amount of  such class  of
Securities.

   
    Notwithstanding  the foregoing, no amendment or  modification may be made to
the Declaration if such amendment or  modification would (i) cause NWPS  Capital
to  be classified for purposes of United States federal income taxation as other
than a grantor  trust, (ii) affect  the powers, rights,  duties, obligations  or
immunities  of  the  Property  Trustee  or  the  Delaware  Trustee  (unless such
amendment is consented to  by the Property Trustee  or the Delaware Trustee,  as
the  case  may be),  or (iii)  cause NWPS  Capital to  be deemed  an "investment
company" which is required to be registered under the 1940 Act.
    

MERGERS, CONSOLIDATIONS OR AMALGAMATIONS

    NWPS Capital may not  consolidate, amalgamate, merge or  be replaced by,  or
convey,  transfer  or  lease  its  properties  and  assets  substantially  as an
entirety, to any  corporation or  other body,  except as  described below.  NWPS
Capital  may, with the consent of a majority of the Regular Trustees and without
the consent of the holders of the Trust Securities, the Delaware Trustee or  the
Property Trustee, consolidate, amalgamate, merge with or into, or be replaced by
a  trust organized as such  under the laws of any  State, provided that (i) such
successor entity either  (x) expressly assumes  all of the  obligations of  NWPS
Capital  under  the  Trust  Securities  or  (y)  substitutes  for  the Preferred
Securities other  securities  (the  "Successor  Securities"),  so  long  as  the
Successor  Securities rank the same as the Trust Securities rank with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii)  the
Company expressly acknowledges a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Subordinated
Debt  Securities, (iii) the Preferred Securities or any Successor Securities are
listed, or  any  Successor  Securities  will  be  listed  upon  notification  of
issuance,  on any national  securities exchange or  with another organization on
which the Preferred  Securities are  then listed  or quoted,  (iv) such  merger,
consolidation,   amalgamation  or  replacement  does  not  cause  the  Preferred
Securities or  any  Successor Securities  to  be downgraded  by  any  nationally
recognized  statistical  rating  organization, (v)  such  merger, consolidation,
amalgamation or replacement  does not adversely  affect the rights,  preferences
and  privileges  of  the  holders  of  the  Trust  Securities  or  any Successor
Securities in  any material  respect  under the  documents governing  the  Trust
Securities  or the Successor Securities (other than with respect to any dilution
of the holders' interest in  the new entity), (vi)  such successor entity has  a
purpose  substantially identical  to that of  NWPS Capital, (vii)  prior to such
merger, consolidation, amalgamation or replacement, the Company has received  an
opinion   of  a  nationally  recognized  independent  counsel  to  NWPS  Capital
experienced in such matters to the effect that, (A) such merger,  consolidation,
amalgamation  or replacement does  not adversely affect  the rights, preferences
and privileges  of  the  holders  of  the  Trust  Securities  or  any  Successor
Securities  in  any material  respect under  the  documents governing  the Trust
Securities or the Successor Securities (other than with respect to any  dilution
of  the holders'  interest in  the new entity),  and (B)  following such merger,
consolidation, amalgamation  or  replacement,  neither  NWPS  Capital  nor  such
successor entity will be required to register as an investment company under the
1940  Act and  (viii) the Company  guarantees the obligations  of such successor
entity under the  Successor Securities at  least to the  extent provided by  the
Guarantee  and the  Common Securities Guarantee.  Notwithstanding the foregoing,
NWPS Capital  shall  not,  except  with  the  consent  of  holders  of  100%  in
liquidation  amount of the Trust Securities, consolidate, amalgamate, merge with
or into,  or be  replaced by  any other  entity or  permit any  other entity  to
consolidate,   amalgamate,  merge  with   or  into,  or   replace  it,  if  such
consolidation, amalgamation, merger or replacement  would cause NWPS Capital  or
the  Successor Entity to be classified as  other than a grantor trust for United
States federal income tax purposes.

                                      S-19

   
    There are no provisions which afford the holders of the Preferred Securities
protection  in  the event  of  a highly  leveraged  transaction, reorganization,
restructuring, merger or  similar transaction involving  the Company. There  are
also no provisions which require the repurchase of the Preferred Securities upon
a change in control of the Company.
    

BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY

   
    The  Depository Trust Company ("DTC") will  act as securities depositary for
the Preferred  Securities.  The Preferred  Securities  will be  issued  only  as
fully-registered  securities  registered  in  the  name  of  Cede  &  Co. (DTC's
nominee). One or more fully-registered global Preferred Securities certificates,
representing the total aggregate number of Preferred Securities, will be  issued
and will be deposited with DTC or a custodian thereof.
    

    The laws of some jurisdictions require that certain purchasers of securities
take  physical delivery of  securities in definitive form.  Such laws may impair
the ability to transfer beneficial interests in the global Preferred  Securities
as represented by a global certificate.

    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,  as amended  (the "Exchange Act").  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 ("Direct Participants").

    DTC  is owned  by a number  of its Direct  Participants and by  the New York
Stock Exchange,  Inc.  (the  "New  York Stock  Exchange"),  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 transactions through or maintain a
direct  or  indirect 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 Securities and Exchange Commission.

    Purchases  of Preferred Securities within the DTC  system must be made by or
through Direct  Participants, which  will  receive a  credit for  the  Preferred
Securities  on DTC's records. The ownership interest of each actual purchaser of
each Preferred 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  purchases, but  Beneficial Owners  are
expected to receive written confirmations providing details of the transactions,
as  well as periodic statements  of their holdings, from  the Direct or Indirect
Participants through which the Beneficial Owners purchased Preferred Securities.
Transfers  of  ownership  interests  in  the  Preferred  Securities  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 Preferred Securities, except in the event that
use of the book-entry system for the Preferred Securities is discontinued.

    To facilitate subsequent transfers,  all the Preferred Securities  deposited
by Participants with DTC are registered in the name of DTC's nominee, Cede & Co.
The  deposit of Preferred Securities 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 Preferred Securities. DTC's records reflect
only the identity of  the Direct Participants to  whose accounts such  Preferred
Securities  are credited,  which may  or may not  be the  Beneficial Owners. The
Participants will remain responsible  for keeping account  of their holdings  on
behalf of their customers.

                                      S-20

    Conveyance   of  notices   and  other   communications  by   DTC  to  Direct
Participants, by  Direct Participants  to Indirect  Participants and  by  Direct
Participants  and Indirect Participants to Beneficial Owners will be governed by
arrangements among them,  subject to  any statutory  or regulatory  requirements
that may be in effect from time to time.

    Redemption  notices shall  be sent  to Cede &  Co. If  less than  all of the
Preferred Securities  are being  redeemed, DTC  will reduce  the amount  of  the
interest  of each Direct Participant in  such Preferred Securities in accordance
with its procedures.

    Although voting  with respect  to the  Preferred Securities  is limited,  in
those  cases where a  vote is required, neither  DTC nor Cede  & Co. will itself
consent  or  vote  with  respect  to  Preferred  Securities.  Under  its   usual
procedures,  DTC would mail an Omnibus Proxy to NWPS Capital as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co. consenting or voting
rights to those Direct Participants  to whose accounts the Preferred  Securities
are credited on the record date (identified in a listing attached to the Omnibus
Proxy).  The Company and  NWPS Capital believe that  the arrangements among DTC,
Direct  and  Indirect  Participants,  and  Beneficial  Owners  will  enable  the
Beneficial  Owners to exercise rights equivalent in substance to the rights that
can be directly exercised by a holder of a beneficial interest in NWPS Capital.

   
    Distribution payments on the Preferred Securities will be made to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings  shown on DTC's records unless  DTC
has  reason to believe that  it will not receive  payments on such payment date.
Payments by  Participants to  Beneficial  Owners will  be governed  by  standing
instructions  and customary practices,  as is the case  with securities held for
the account of customers in bearer form or registered in "street name," and such
payments will be  the responsibility of  such Participant and  not of DTC,  NWPS
Capital  or the Company, subject to  any statutory or regulatory requirements to
the contrary that may be in effect  from time to time. Payment of  distributions
to  DTC is the responsibility of NWPS  Capital, disbursement of such payments to
Direct Participants  is the  responsibility  of DTC,  and disbursement  of  such
payments  to the Beneficial Owners is  the responsibility of Direct and Indirect
Participants.
    

    Except as provided herein, a Beneficial Owner in a global Preferred Security
certificate will  not be  entitled  to receive  physical delivery  of  Preferred
Securities.  Accordingly, each Beneficial  Owner must rely  on the procedures of
DTC to exercise any rights under the Preferred Securities.

    DTC may discontinue  providing its  services as  securities depositary  with
respect  to the Preferred Securities at any  time by giving reasonable notice to
NWPS Capital. Under such circumstances, in the event that a successor securities
depositary is not obtained, Preferred Securities certificates are required to be
printed and delivered. Additionally, the  Regular Trustees (with the consent  of
the Company) may decide to discontinue use of the system of book-entry transfers
through  DTC  (or  any  successor  depositary)  with  respect  to  the Preferred
Securities. In that  event, certificates  for the Preferred  Securities will  be
printed and delivered.

   
    The  information in this section concerning  DTC and DTC's book-entry system
has been obtained from sources that the  Company and NWPS Capital believe to  be
reliable,  but neither the Company nor NWPS Capital takes responsibility for the
accuracy thereof.
    

INFORMATION CONCERNING THE PROPERTY TRUSTEE

    The Property Trustee, prior to the  occurrence of a default with respect  to
the Trust Securities, undertakes to perform only such duties as are specifically
set  forth in the Declaration and, after default, shall exercise the same degree
of care as a prudent individual would exercise in the conduct of his or her  own
affairs.

    Subject  to such provisions, the Property  Trustee is under no obligation to
exercise any of the powers vested in it by the Declaration at the request of any
holder of  Preferred Securities,  unless offered  reasonable indemnity  by  such
holder   against   the  costs,   expenses   and  liabilities   which   might  be

                                      S-21

incurred thereby. The holders  of Preferred Securities will  not be required  to
offer  such  indemnity in  the event  such holders,  by exercising  their voting
rights, direct the Property Trustee to  take any action following a  Declaration
Event of Default.

PAYING AGENT

    In  the event that the Preferred Securities do not remain in book-entry only
form, the following provisions would apply:

    The Property  Trustee  will  act  as paying  agent,  and  may  designate  an
additional or substitute paying agent at any time.

    Registration  of transfers of Preferred  Securities will be effected without
charge by or on  behalf of NWPS  Capital, but upon payment  (with the giving  of
such indemnity as NWPS Capital or the Company may require) in respect of any tax
or other government charges that may be imposed in relation to it.

    NWPS  Capital will not be required to register or cause to be registered the
transfer of  Preferred  Securities after  such  Preferred Securities  have  been
called for redemption.

GOVERNING LAW

    The  Declaration  and  the Preferred  Securities  will be  governed  by, and
construed in accordance with, the internal laws of the State of Delaware.

MISCELLANEOUS

    The Regular Trustees are authorized and directed to operate NWPS Capital  in
such  a way  so that NWPS  Capital will  not be (i)  required to  register as an
"investment company" under the  1940 Act or (ii)  characterized as other than  a
grantor  trust for  United States  federal income  tax purposes.  The Company is
authorized and directed  to conduct its  affairs so that  the Subordinated  Debt
Securities  will be  treated as  indebtedness of  the Company  for United States
federal income tax  purposes. In this  connection, the Company  and the  Regular
Trustees  are authorized  to take any  action, not  inconsistent with applicable
law,  the  certificate  of  trust  of   NWPS  Capital  or  the  certificate   of
incorporation  of the Company, that each of the Company and the Regular Trustees
determines in its discretion to be  necessary or desirable to achieve such  end,
as long as such action does not adversely affect the interests of the holders of
the Preferred Securities or vary the terms thereof.

    Holders of the Preferred Securities have no preemptive rights.

                DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

    Set  forth below is a description of  the specific terms of the Subordinated
Debt Securities in which NWPS Capital will invest the proceeds from the issuance
and sale of the Trust  Securities. This description supplements the  description
of  the general  terms and  provisions of  the Subordinated  Debt Securities set
forth in  the accompanying  Prospectus  under the  caption "Description  of  the
Subordinated  Debt Securities." The following description does not purport to be
complete and is subject to,  and is qualified in  its entirety by reference  to,
the  description  in  the  accompanying  Prospectus  and  the  Subordinated Debt
Securities Indenture, dated  as of               , 1995  (the "Base  Indenture")
between  the  Company  and The  Chase  Manhattan  Bank (N.A.),  as  Trustee (the
"Indenture Trustee"), as supplemented by  a First Supplemental Indenture,  dated
as  of            , 1995 (the Base Indenture, as so supplemented, is hereinafter
referred to as the "Indenture"), the forms of which are filed as Exhibits to the
Registration Statement of which this Prospectus Supplement and the  accompanying
Prospectus form a part. Certain capitalized terms used herein are defined in the
Indenture.

    Under  certain  circumstances  involving  the  dissolution  of  NWPS Capital
following the occurrence of a Special Event, Subordinated Debt Securities may be
distributed to  the holders  of  the Trust  Securities  in liquidation  of  NWPS
Capital.   See  "Description  of  the  Preferred  Securities  --  Special  Event
Redemption or Distribution."

                                      S-22

    If the Subordinated Debt  Securities are distributed to  the holders of  the
Preferred  Securities,  the  Company  will  use its  best  efforts  to  have the
Subordinated Debt Securities listed  on the New York  Stock Exchange or on  such
other  national  securities  exchange  or  similar  organization  on  which  the
Preferred Securities are then listed or quoted.

GENERAL

   
    The Subordinated Debt Securities will be issued as unsecured debt under  the
Indenture.  The  Subordinated  Debt  Securities  will  be  limited  in aggregate
principal amount to approximately $31 million, such amount being the sum of  the
aggregate  stated liquidation amount of the Preferred Securities and the capital
contributed by the Company in exchange  for the Common Securities (the  "Company
Payment").
    

   
    The  Subordinated  Debt  Securities  are  not  subject  to  a  sinking  fund
provision. The entire principal amount of the Subordinated Debt Securities  will
mature and become due and payable, together with any accrued and unpaid interest
thereon  including  Compound Interest  (as  hereinafter defined)  and Additional
Interest (as hereinafter defined), if any, on             , 2025 subject to  the
election   of  the  Company  to  extend  the  scheduled  maturity  date  of  the
Subordinated Debt Securities to a date  not later than             , 2044  which
election  is subject  to the Company's  satisfying certain conditions.  See " --
Option to Extend Maturity."
    

    If Subordinated  Debt Securities  are distributed  to holders  of  Preferred
Securities  in  liquidation of  such holders'  interests  in NWPS  Capital, such
Subordinated Debt Securities will initially be  issued as a Global Security.  As
described   herein,  under  certain  limited  circumstances,  Subordinated  Debt
Securities may be issued in certificated form in exchange for a Global  Security
(as  defined below).  See "Book-Entry and  Settlement" below. In  the event that
Subordinated Debt Securities are issued in certificated form, such  Subordinated
Debt  Securities will be in denominations  of $25 and integral multiples thereof
and may be transferred or exchanged at the offices described below. Payments  on
Subordinated  Debt Securities issued as a Global Security will be made to DTC, a
successor depositary or, in the  event that no depositary  is used, to a  Paying
Agent  for  the Subordinated  Debt Securities.  In  the event  Subordinated Debt
Securities are  issued in  certificated  form, principal  and interest  will  be
payable,  the transfer of  the Subordinated Debt  Securities will be registrable
and Subordinated  Debt Securities  will be  exchangeable for  Subordinated  Debt
Securities  of other denominations  of a like aggregate  principal amount at the
corporate trust office of the Indenture Trustee in Brooklyn, New York;  provided
that,  payment of  interest may be  made at the  option of the  Company by check
mailed to the address of the persons entitled thereto.

SUBORDINATION

    The  Indenture   provides  that   the  Subordinated   Debt  Securities   are
subordinated  and junior in right  of payment to all  Senior Indebtedness of the
Company.  No  payment  of  principal  (including  redemption  and  sinking  fund
payments),  premium, if any, or interest on the Subordinated Debt Securities may
be made (i) if any Senior Indebtedness of the Company is not paid when due, (ii)
any applicable grace  period with  respect to such  default has  ended and  such
default  has  not been  cured or  waived or  ceased  to exist,  or (iii)  if the
maturity of any Senior Indebtedness of the Company has been accelerated  because
of  a default. Upon any distribution of  assets of the Company to creditors upon
any dissolution, winding-up, liquidation or reorganization, whether voluntary or
involuntary, or in  bankruptcy, insolvency, receivership  or other  proceedings,
all  principal, premium, if any, and interest due or to become due on all Senior
Indebtedness of  the  Company  must  be  paid in  full  before  the  holders  of
Subordinated Debt Securities are entitled to receive or retain any payment. Upon
satisfaction  of all  claims of  all Senior  Indebtedness then  outstanding, the
rights of the holders of the Subordinated Debt Securities will be subrogated  to
the  rights of  the holders  of Senior  Indebtedness of  the Company  to receive
payments or distributions  applicable to Senior  Indebtedness until all  amounts
owing on the Subordinated Debt Securities are paid in full.

    The  term "Senior Indebtedness" means, with  respect to the Company, (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of  such
obligor for money borrowed and

                                      S-23

(B)  indebtedness evidenced  by securities,  debentures, bonds  or other similar
instruments issued by such obligor including, without limitation, in the case of
the Company, all obligations under its New Mortgage and 1940 Indenture (each  as
defined  in the accompanying Prospectus), (ii)  all capital lease obligations of
such obligor, (iii)  all obligations of  such obligor issued  or assumed as  the
deferred  purchase price of  property, all conditional  sale obligations of such
obligor and all obligations of such obligor under any title retention  agreement
(but  excluding  trade  accounts  payable  arising  in  the  ordinary  course of
business), (iv) all  obligations of such  obligor for the  reimbursement on  any
letter  of credit,  banker's acceptance,  security purchase  facility or similar
credit transaction, (v) all obligations of  the type referred to in clauses  (i)
through  (iv) above of  other persons for  the payment of  which such obligor is
responsible  or  liable  as  obligor,  guarantor  or  otherwise,  and  (vi)  all
obligations  of the type referred  to in clauses (i)  through (v) above of other
persons secured by any lien on any property or asset of such obligor (whether or
not such  obligation  is assumed  by  such obligor),  except  for (1)  any  such
indebtedness  that  is by  its  terms subordinated  to  or pari  passu  with the
Subordinated Debt  Securities and  (2) any  indebtedness between  or among  such
obligor or its affiliates, including all other debt securities and guarantees in
respect of those debt securities issued, to (a) any other NWPS Trust (as defined
in  the accompanying Prospectus), or a trustee  of such trust, and (b) any other
trust, or a trustee of such  trust, partnership or other entity affiliated  with
the Company that is a financing vehicle of the Company (a "financing entity") in
connection with the issuance by such financing entity of Preferred Securities or
other  securities  that  rank  pari  passu with,  or  junior  to,  the Preferred
Securities. Such Senior  Indebtedness shall continue  to be Senior  Indebtedness
and  be entitled to the benefits of the subordination provisions irrespective of
any amendment, modification or waiver of any term of such Senior Indebtedness.

    The Indenture does  not limit  the aggregate amount  of Senior  Indebtedness
that  may be issued by the Company. As of March 31, 1995, Senior Indebtedness of
the Company aggregated approximately $124 million.

OPTIONAL REDEMPTION

   
    The Company shall have the right to redeem the Subordinated Debt Securities,
in whole or in part, from time to  time, on or after          , 2000, or at  any
time  in certain circumstances upon  the occurrence of a  Tax Event as described
under "Description of the  Preferred Securities --  Special Event Redemption  or
Distribution,"  upon  not  less than  30  nor more  than  60 days  notice,  at a
redemption price equal to 100% of the  principal amount to be redeemed plus  any
accrued  and  unpaid interest,  including Additional  Interest,  if any,  to the
redemption date. If a partial  redemption of the Preferred Securities  resulting
from  a partial redemption  of the Subordinated Debt  Securities would result in
the delisting  of the  Preferred Securities,  the Company  may only  redeem  the
Subordinated Debt Securities in whole.
    

INTEREST

   
    Each  Subordinated Debt Security shall bear interest at the rate of    % per
annum (the "Coupon Rate") from the original date of issuance until the principal
becomes due  and  payable, and  on  any overdue  principal  and on  any  overdue
installment  of  interest  at  the Coupon  Rate,  compounded  quarterly, payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of  each
year  (each, an "Interest Payment Date"),  commencing             , 1995, to the
person in whose name such Subordinated Debt Security is registered, at the close
of business on the  Business Day next preceding  such Interest Payment Date.  In
the  event  the Subordinated  Debt Securities  shall not  continue to  remain in
book-entry only form, the Company shall  have the right to select record  dates,
which  shall be any date at least one Business Day prior to the Interest Payment
Date. It  is anticipated  that  NWPS Capital  will be  the  sole holder  of  the
Subordinated Debt Securities.
    

   
    The  amount of interest payable for any period will be computed on the basis
of a 360-day year of  twelve 30-day months. The  amount of interest payable  for
any  period shorter than a full quarterly  period for which interest is computed
will be computed on the  basis of the actual number  of days elapsed per  30-day
month.  In  the  event  that  any  date on  which  interest  is  payable  on the
Subordinated
    

                                      S-24

Debt Securities is not a Business Day,  then payment of the interest payable  on
such  date will be made on  the next succeeding day that  is a Business Day (and
without any interest  or other  payment in respect  of any  such delay),  except
that,  if such Business Day  is in the next  succeeding calendar year, then such
payment shall be made  on the immediately preceding  Business Day, in each  case
with the same force and effect as if made on such date.

OPTION TO EXTEND MATURITY DATE

   
    The  maturity date of the Subordinated Debt Securities is             , 2025
(the "Scheduled Maturity Date"). The Company, however, may, before the Scheduled
Maturity Date, extend  such maturity date  no more than  one time for  up to  an
additional  19 years  from the  Scheduled Maturity  Date; provided  that (a) the
Company is not in bankruptcy or otherwise  insolvent, (b) the Company is not  in
default  on any Subordinated  Debt Securities issued  to a NWPS  Trust or to any
trustee of such trust in connection with an issuance of Trust Securities by such
NWPS Trust, (c) the  Company has made timely  payments on the Subordinated  Debt
Securities  for the  immediately preceding  six quarters  without deferrals, (d)
NWPS Capital is  not in arrears  on payments of  distributions on the  Preferred
Securities,  (e) the Subordinated Debt Securities  are rated Investment Grade by
any one of  Standard &  Poor's Rating  Group, Moody's  Investors Service,  Inc.,
Fitch  Investor  Services, Duff  &  Phelps Credit  Rating  Company or  any other
nationally  recognized  statistical  rating  organization,  and  (g)  the  final
maturity  of  such  Subordinated Debt  Securities  is  not later  than  the 49th
anniversary of  the  issuance  of  the Preferred  Securities.  Pursuant  to  the
Declaration,  the Regular Trustees are required  to give notice of the Company's
election to extend the Scheduled Maturity  Date to the holders of the  Preferred
Securities.
    

   
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
    

   
    If  (i) NWPS  Capital fails  to pay distributions  in full  on the Preferred
Securities  for  six  consecutive  quarterly  distribution  periods  or  (ii)  a
Declaration  Event of Default (as defined herein) occurs and is continuing, then
the holders of  Preferred Securities  would be  entitled, by  majority vote,  to
appoint  a Special Regular Trustee,  who shall have the  same rights, powers and
privileges as the other Regular Trustees. In addition, the holders of a majority
in aggregate liquidation amount of the Preferred Securities will have the  right
to:  (i) direct the time, method, and place of conducting any proceeding for any
remedy available to the Property Trustee or to direct the exercise of any  trust
or  power conferred upon the Property  Trustee under the Declaration; (ii) waive
any past default; or (iii) exercise any right to rescind or annul a  declaration
that  the principal  of all  the Subordinated Debt  Securities shall  be due and
payable; provided, however, that  where a consent  under the Indenture  requires
the consent of all holders of the Subordinated Debt Securities affected thereby,
the  Property Trustee may only give such consent at the direction of all holders
of the Preferred Securities. If the Property Trustee fails to enforce its rights
under the Subordinated Debt Securities, to the fullest extent permitted by  law,
a holder of Preferred Securities may, after such holder's written request to the
Property  Trustee to enforce such rights,  institute a legal proceeding directly
against  the  Company  to  enforce  the  Property  Trustee's  rights  under  the
Subordinated  Debt  Securities without  first  instituting any  legal proceeding
against the  Property Trustee  or any  other person  or entity.  If the  Company
exercises  its  right to  defer payments  of interest  on the  Subordinated Debt
Securities (See "Option to Extend Interest Payment Period" below) appointment of
a Special  Regular  Trustee would  be  the only  right  of the  holders  of  the
Preferred  Securities if NWPS Capital fails to  pay distributions in full on the
Preferred Securities  for  six  consecutive quarters  until  expiration  of  the
extended interest payment period (20 consecutive quarters).
    

OPTION TO EXTEND INTEREST PAYMENT PERIOD

    The  Company shall have the right at any time, and from time to time, during
the term of the  Subordinated Debt Securities to  defer payments of interest  by
extending  the interest payment period for a period not exceeding 20 consecutive
quarters, at  the end  of which  Extension  Period, the  Company shall  pay  all
interest  then accrued and unpaid (including  any Additional Interest, as herein
defined) together  with  interest  thereon  compounded  quarterly  at  the  rate
specified  for  the  Subordinated Debt  Securities  to the  extent  permitted by
applicable law ("Compound Interest"); provided that, during

                                      S-25

any such  Extension  Period,  (a) the  Company  shall  not declare  or  pay  any
dividends  on,  make  any distribution  with  respect to,  or  redeem, purchase,
acquire or make a liquidation payment with respect to, any of its capital  stock
and  (b)  the Company  shall  not make  any  payment of  interest,  principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
the Company  that  rank pari  passu  with or  junior  to the  Subordinated  Debt
Securities;  provided,  however, that,  the foregoing  restriction (a)  does not
apply to any stock dividends paid by the Company where the dividend stock is the
same as that on which the dividend is paid.

    Prior to  the termination  of any  such Extension  Period, the  Company  may
further  defer payments  of interest by  extending the  interest payment period;
provided, however, that, such Extension Period, including all such previous  and
further extensions, may not exceed 20 consecutive quarters. Upon the termination
of any Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the terms set forth in this section.
No  interest during an Extension Period, except at the end thereof, shall be due
and payable. The  Company has no  present intention of  exercising its right  to
defer  payments  of interest  by extending  the interest  payment period  on the
Subordinated Debt Securities. If the Property  Trustee shall be the sole  holder
of the Subordinated Debt Securities, the Company shall give the Regular Trustees
and  the Property Trustee notice  of its selection of  such Extension Period one
Business Day prior to the earlier of (i) the date distributions on the Preferred
Securities are payable  or (ii) the  date the Regular  Trustees are required  to
give  notice to the New York Stock Exchange (or other applicable self-regulatory
organization) or to holders  of the Preferred Securities  of the record date  or
the date such distribution is payable. The Regular Trustees shall give notice of
the Company's selection of such Extension Period to the holders of the Preferred
Securities.  If  the  Property Trustee  shall  not  be the  sole  holder  of the
Subordinated Debt  Securities,  the  Company  shall  give  the  holders  of  the
Subordinated  Debt Securities notice  of its selection  of such Extension Period
ten Business Days prior to the earlier of (i) the Interest Payment Date or  (ii)
the date upon which the Company is required to give notice to the New York Stock
Exchange (or other applicable self-regulatory organization) or to holders of the
Subordinated  Debt  Securities of  the record  or payment  date of  such related
interest payment.

ADDITIONAL INTEREST

    If at any time while the Property Trustee is the holder of the  Subordinated
Debt  Securities,  NWPS Capital  shall  be required  to  pay any  taxes, duties,
assessments or governmental charges of  whatever nature (other than  withholding
taxes) imposed by the United States, or any other taxing authority, then, in any
such  case, the Company will pay  as additional interest ("Additional Interest")
on the Subordinated Debt Securities such additional amounts as shall be required
so that the net amounts received and  retained by NWPS Capital after paying  any
such  taxes, duties, assessments or other  governmental charges will be not less
than the amounts  NWPS Capital would  have received had  no such taxes,  duties,
assessments or other governmental charges been imposed.

INDENTURE EVENTS OF DEFAULT

    If  any  Indenture  Event of  Default  shall  occur and  be  continuing, the
Property Trustee, as the holder of  the Subordinated Debt Securities, will  have
the  right to declare the principal of and the interest on the Subordinated Debt
Securities (including any Compound Interest and Additional Interest, if any) and
any other amounts payable  under the Indenture to  be forthwith due and  payable
and  to enforce its other rights as  a creditor with respect to the Subordinated
Debt Securities. See "Description of the Subordinated Debt Securities --  Events
of  Default" in the accompanying  Prospectus for a description  of the Events of
Default. An Indenture Event of Default  also constitutes a Declaration Event  of
Default.  The holders of Preferred Securities  in certain circumstances have the
right to direct the Property Trustee to exercise its rights as the holder of the
Subordinated Debt Securities.  See "Description of  the Preferred Securities  --
Declaration Events of Default" and "Voting Rights."

BOOK-ENTRY AND SETTLEMENT

    If  distributed to  holders of Preferred  Securities in  connection with the
involuntary or voluntary dissolution, winding-up or liquidation of NWPS  Capital
as a result of the occurrence of a Special

                                      S-26

Event,  the Subordinated Debt  Securities will be  issued in the  form of one or
more global certificates (each, a "Global  Security") registered in the name  of
the  Depositary or its nominee. Except under the limited circumstances described
below, Subordinated Debt Securities represented by the Global Security will  not
be  exchangeable for, and  will not otherwise be  issuable as, Subordinated Debt
Securities in definitive form. The Global Securities described above may not  be
transferred  except 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 to a successor depositary or its nominee.

    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery  of such  securities in  definitive form.  Such laws  may
impair the ability to transfer beneficial interests in such a Global Security.

    Except  as provided below,  owners of beneficial interests  in such a Global
Security will not be entitled to receive physical delivery of Subordinated  Debt
Securities in definitive form and will not be considered the holders (as defined
in  the Indenture) thereof  for any purpose  under the Indenture,  and no Global
Security representing Subordinated Debt Securities shall be exchangeable, except
for another Global Security of like  denomination and tenor to be registered  in
the  name of the Depositary  or its nominee or to  a successor Depositary or its
nominee. Accordingly, each Beneficial Owner must  rely on the procedures of  the
Depositary  or if  such person is  not a  Participant, on the  procedures of the
Participant through which such person owns  its interest to exercise any  rights
of a holder under the Indenture.

THE DEPOSITARY

    If  Subordinated  Debt Securities  are distributed  to holders  of Preferred
Securities in liquidation of such holders'  interests in NWPS Capital, DTC  will
act  as  securities  depositary  for the  Subordinated  Debt  Securities.  For a
description of DTC and  the specific terms of  the depositary arrangements,  see
"Description  of the  Preferred Securities  -- Book-Entry  Only Issuance  -- The
Depository Trust Company."  As of the  date of this  Prospectus Supplement,  the
description  therein  of DTC's  book-entry system  and  DTC's practices  as they
relate to  purchases,  transfers,  notices  and payments  with  respect  to  the
Preferred  Securities apply  in all  material respects  to any  debt obligations
represented by  one or  more Global  Securities  held by  DTC. The  Company  may
appoint  a successor to DTC or any successor depositary in the event DTC or such
successor depositary is unable or unwilling to continue as a depository for  the
Global Securities.

    None  of the Company, NWPS Capital,  the Indenture Trustee, any paying agent
and any  other agent  of the  Company or  the Indenture  Trustee will  have  any
responsibility  or  liability  for any  aspect  of  the records  relating  to or
payments made on account of beneficial ownership interests in a Global  Security
for  such  Subordinated  Debt  Securities  or  for  maintaining,  supervising or
reviewing any records relating to such beneficial ownership interests.

DISCONTINUANCE OF THE DEPOSITARY'S SERVICES

    A Global Security  shall be  exchangeable for  Subordinated Debt  Securities
registered in the names of persons other than the depositary or its nominee only
if  (i) the depositary  notifies the Company  that it is  unwilling or unable to
continue as a depositary  for such Global Security  and no successor  depositary
shall  have been  appointed, (ii) the  depositary, at  any time, ceases  to be a
clearing agency registered under the Exchange  Act at which time the  depositary
is  required to  be so  registered to  act as  such depositary  and no successor
depositary shall have been appointed, (iii) the Company, in its sole discretion,
determines that such  Global Security  shall be  so exchangeable  or (iv)  there
shall  have occurred an Event of Default  with respect to such Subordinated Debt
Securities. Any Global Security that  is exchangeable pursuant to the  preceding
sentence  shall be exchangeable  for Subordinated Debt  Securities registered in
such names as the depositary shall direct. It is expected that such instructions
will be based upon directions received  by the depositary from its  Participants
with respect to ownership of beneficial interests in such Global Security.

                                      S-27

MISCELLANEOUS

   
    The  Indenture will provide that the Company  will pay all fees and expenses
related to (i) the  offering of the Trust  Securities and the Subordinated  Debt
Securities,  (ii) the organization, maintenance and dissolution of NWPS Capital,
(iii) the  retention  of the  NWPS  Trustees and  (iv)  the enforcement  by  the
Property  Trustee of the rights of the  holders of the Preferred Securities. The
payment of such fees and expenses  will be fully and unconditionally  guaranteed
by the Company.
    

                        EFFECT OF OBLIGATIONS UNDER THE
                 SUBORDINATED DEBT SECURITIES AND THE GUARANTEE

    As  set forth  in the Declaration,  the sole  purpose of NWPS  Capital is to
issue the  Trust Securities  evidencing undivided  beneficial interests  in  the
assets  of NWPS Capital, and to invest  the proceeds from such issuance and sale
in the Subordinated Debt Securities.

    As long as payments of interest and other payments are made when due on  the
Subordinated  Debt  Securities,  such  payments  will  be  sufficient  to  cover
distributions and payments due on the Trust Securities because of the  following
factors: (i) the aggregate principal amount of Subordinated Debt Securities will
be  equal to  the sum of  the aggregate  stated liquidation amount  of the Trust
Securities; (ii) the interest rate and  the interest and other payment dates  on
the   Subordinated  Debt  Securities  will   match  the  distribution  rate  and
distribution and other  payment dates  for the Preferred  Securities; (iii)  the
Company  shall  pay  all costs  and  expenses of  the  Trust to  the  extent not
satisfied out of the Trust's assets;  and (iv) the Declaration further  provides
that  the NWPS Trustees shall  not cause or permit  NWPS Capital to, among other
things, engage in any activity that is not consistent with the purposes of  NWPS
Capital.

    Payments  of  distributions  (to  the  extent  funds  therefor  are  legally
available) and other  payments due on  the Preferred Securities  (to the  extent
funds  therefor are legally available)  are guaranteed by the  Company as and to
the extent set forth under "Description  of the Guarantees" in the  accompanying
Prospectus.  If the Company does not  make interest payments on the Subordinated
Debt Securities purchased by NWPS Capital, it is expected that NWPS Capital will
not have sufficient funds to pay distributions on the Preferred Securities.  The
Guarantee  is a full and  unconditional guarantee from the  time of its issuance
but does not apply to any payment of distributions unless and until NWPS Capital
has sufficient funds legally available for the payment of such distributions.

   
    If the Company fails to make interest or other payments on the  Subordinated
Debt  Securities  when  due  (taking  account  of  any  Extension  Period),  the
Declaration  provides  a  mechanism  whereby   the  holders  of  the   Preferred
Securities,  using  the procedures  described in  "Description of  the Preferred
Securities -- Book-Entry Only Issuance -- The Depository Trust Company" and  "--
Voting  Rights," may (i) appoint  a Special Regular Trustee  and (ii) direct the
Property Trustee to enforce its  rights under the Subordinated Debt  Securities.
If  the Property Trustee fails to enforce its rights under the Subordinated Debt
Securities, to  the fullest  extent  permitted by  law,  a holder  of  Preferred
Securities  may, after such holder's written  request to the Property Trustee to
enforce such rights, institute a legal proceeding against the Company to enforce
the Property Trustee's  rights under  the Subordinated  Debt Securities  without
first instituting any legal proceeding against the Property Trustee or any other
person  or  entity.  The Company,  under  the Guarantee,  acknowledges  that the
Guarantee Trustee shall enforce  the Guarantee on behalf  of the holders of  the
Preferred Securities. If the Company fails to make payments under the Guarantee,
the  Guarantee  provides  a  mechanism  whereby  the  holders  of  the Preferred
Securities may direct the Guarantee Trustee to enforce its rights thereunder. If
the Guarantee Trustee fails  to enforce the Guarantee,  any holder of  Preferred
Securities  may, after such holder's written request to the Guarantee Trustee to
enforce the Guarantee, institute a legal proceeding directly against the Company
to enforce  the Guarantee  Trustee's rights  under the  Guarantee without  first
instituting  a legal proceeding against NWPS  Capital, the Guarantee Trustee, or
any other person.
    

                                      S-28

    The  Company  and  NWPS  Capital  believe  that  the  above  mechanisms  and
obligations,  taken  together,  are  substantially  equivalent  to  a  full  and
unconditional guarantee  by  the  Company  of  payments  due  on  the  Preferred
Securities.  See "Description of the Guarantees  -- General" in the accompanying
Prospectus.

                     UNITED STATES FEDERAL INCOME TAXATION

GENERAL

    The following is a summary of certain of the material United States  federal
income  tax consequences of the purchase, ownership and disposition of Preferred
Securities. Unless  otherwise stated,  this summary  deals only  with  Preferred
Securities  held  as  capital  assets  by  holders  who  purchase  the Preferred
Securities upon original  issuance ("Initial  Holders"). It does  not deal  with
special  classes  of  holders such  as  banks, thrifts,  real  estate investment
trusts,  regulated  investment  companies,   insurance  companies,  dealers   in
securities  or currencies, tax-exempt  investors, or persons  that will hold the
Preferred Securities as  a position  in a "straddle,"  as part  of a  "synthetic
security"  or "hedge," as part of a "conversion transaction" or other integrated
investment, or as other than a capital asset. This summary also does not address
the tax consequences to persons whose functional currency is other than the U.S.
Dollar or the tax consequences to  shareholders, partners or beneficiaries of  a
holder  of Preferred Securities. Further, it does not include any description of
any alternative minimum tax consequences or the  tax laws of any state or  local
government  or of any foreign government that may be applicable to the Preferred
Securities. This  summary is  based on  the Internal  Revenue Code  of 1986,  as
amended  (the "Code"),  Treasury regulations  thereunder and  administrative and
judicial interpretations  thereof, as  of  the date  hereof,  all of  which  are
subject to change, possibly on a retroactive basis.

CLASSIFICATION OF THE SUBORDINATED DEBT SECURITIES

    In  connection with the issuance of the Subordinated Debt Securities, Schiff
Hardin & Waite, special tax counsel to the Company and NWPS Capital, will render
its opinion generally to the effect that, although not entirely free from doubt,
under then  current law  and assuming  full  compliance with  the terms  of  the
Indenture  (and  certain  other  documents),  and  based  on  certain  facts and
assumptions contained in such opinion, the Subordinated Debt Securities held  by
NWPS Capital will be classified for United States federal income tax purposes as
indebtedness of the Company.

CLASSIFICATION OF NWPS CAPITAL

    In connection with the issuance of the Preferred Securities, Schiff Hardin &
Waite,  special tax  counsel to  the Company and  NWPS Capital,  will render its
opinion generally to the effect that,  under then current law and assuming  full
compliance  with the  terms of  the Declaration  and the  Indenture (and certain
other documents), and based on certain  facts and assumptions contained in  such
opinion,  NWPS Capital will  be classified for United  States federal income tax
purposes as a grantor trust and not as an association taxable as a  corporation.
Accordingly,  for  United States  federal income  tax  purposes, each  holder of
Preferred Securities will be  considered the owner of  an undivided interest  in
the Subordinated Debt Securities, and each holder will be required to include in
its gross income any original issue discount ("OID") accrued with respect to its
allocable share of those Subordinated Debt Securities.

ORIGINAL ISSUE DISCOUNT

   
    Because the Company has the option, under the terms of the Subordinated Debt
Securities,  to defer payments of interest by extending interest payment periods
for up  to  20  quarters, all  payments  in  respect of  the  Subordinated  Debt
Securities  will  be  treated  as "original  issue  discount."  Holders  of debt
instruments issued with OID must include that discount in income on an  economic
accrual  basis  before  the  receipt  of  cash  attributable  to  the  interest,
regardless of  their method  of tax  accounting. Generally,  all of  a  holder's
taxable interest income with respect to the Subordinated Debt Securities will be
accounted  for as OID, and  actual distributions of stated  interest will not be
separately reported as  taxable income. The  amount of OID  that accrues in  any
month  will approximately equal the  amount of the interest  that accrues on the
Subordinated Debt Securities in that month at the stated
    

                                      S-29

interest rate.  In the  event  that the  interest  payment period  is  extended,
holders  will continue to  accrue OID approximately  equal to the  amount of the
interest payment due at the end of  the Extension Period on an economic  accrual
basis over the length of the extended interest period.

    Corporate  holders  of  Preferred  Securities  will  not  be  entitled  to a
dividends received deduction with respect to any income recognized with  respect
to the Preferred Securities.

MARKET DISCOUNT AND BOND PREMIUM

    Holders of Preferred Securities other than Initial Holders may be considered
to  have acquired their undivided interests  in the Subordinated Debt Securities
with market discount  or acquisition  premium as  such phrases  are defined  for
United  States federal income tax purposes.  Such holders are advised to consult
their tax  advisors  as to  the  income  tax consequences  of  the  acquisition,
ownership and disposition of the Preferred Securities.

RECEIPT OF SUBORDINATED DEBT SECURITIES OR CASH UPON LIQUIDATION OF NWPS CAPITAL

    Under  certain circumstances, as described under the caption "Description of
the  Preferred  Securities  --   Special  Event  Redemption  or   Distribution,"
Subordinated  Debt Securities may be distributed  to holders in exchange for the
Preferred Securities and in liquidation of NWPS Capital. Under current law, such
a distribution, for United States federal income tax purposes, would be  treated
as  a  non-taxable  event to  each  holder,  and each  holder  would  receive an
aggregate tax basis in the Subordinated  Debt Securities equal to such  holder's
aggregate  tax basis in  its Preferred Securities. A  holder's holding period in
the Subordinated  Debt Securities  so received  in liquidation  of NWPS  Capital
would include the period during which the Preferred Securities were held by such
holder.

    Under  certain  circumstances  described  herein  (see  "Description  of the
Preferred  Securities  --  Special  Event  Redemption  or  Distribution"),   the
Subordinated  Debt Securities may be redeemed for  cash and the proceeds of such
redemption distributed to holders in  redemption of their Preferred  Securities.
Under current law, such a redemption would, for United States federal income tax
purposes, constitute a taxable disposition of the redeemed Preferred Securities,
and  a holder could recognize gain or loss as if it sold such redeemed Preferred
Securities for cash.  See "United  States Federal  Income Taxation  -- Sales  of
Preferred Securities."

SALES OF PREFERRED SECURITIES

    A  holder that sells Preferred Securities  will recognize gain or loss equal
to the difference between its adjusted tax basis in the Preferred Securities and
the amount  realized  on the  sale  of  such Preferred  Securities.  A  holder's
adjusted  tax basis  in the Preferred  Securities generally will  be its initial
purchase price increased  by OID  previously includible in  such holder's  gross
income  to the  date of  disposition and decreased  by payments  received on the
Preferred Securities. Such gain or loss generally will be a capital gain or loss
and generally  will  be  a long-term  capital  gain  or loss  if  the  Preferred
Securities have been held for more than one year.

    The  Preferred  Securities may  trade at  a price  that does  not accurately
reflect the value of accrued but unpaid interest with respect to the  underlying
Subordinated  Debt Securities. A holder who disposes of his Preferred Securities
between record dates for payments of  distributions thereon will be required  to
include  accrued but unpaid interest on the Subordinated Debt Securities through
the date of disposition in income as ordinary income, and to add such amount  to
his adjusted tax basis in his pro rata share of the underlying Subordinated Debt
Securities  deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis (which will include, in the form of OID, all accrued
but unpaid interest) a holder will recognize a capital loss. Subject to  certain
limited  exceptions, capital losses cannot be  applied to offset ordinary income
for United States federal income tax purposes.

                                      S-30

UNITED STATES ALIEN HOLDERS

    For  purposes  of this  discussion, a  "United States  Alien Holder"  is any
corporation, individual, partnership, estate or trust that is, as to the  United
States,  a  foreign  corporation,  a non-resident  alien  individual,  a foreign
partnership, or a non-resident fiduciary of a foreign estate or trust.

    Under present United  States federal income  tax law: (i)  payments by  NWPS
Capital  or any of its paying agents to  any holder of a Preferred Security that
is a United States  Alien Holder will  not be subject  to United States  federal
withholding  tax;  provided  that  (a) the  beneficial  owner  of  the Preferred
Security does  not actually  or constructively  own  10% or  more of  the  total
combined  voting power of all classes of  stock of the Company entitled to vote,
(b) the beneficial owner of the  Preferred Security is not a controlled  foreign
corporation  that is  related to  the Company  through stock  ownership, and (c)
either (A) the  beneficial owner  of the  Preferred Security  certifies to  NWPS
Capital or its agent, under penalties of perjury, that it is not a United States
holder  and  provides  its  name  and  address  or  (B)  a  securities  clearing
organization,  bank  or  other  financial  institution  that  holds   customers'
securities  in  the  ordinary course  of  its  trade or  business  (a "Financial
Institution"), and holds the Preferred  Security in such capacity, certifies  to
NWPS  Capital or its agent, under penalties  of perjury, that such statement has
been received from  the beneficial  owner by it  or by  a Financial  Institution
between it and the beneficial owner and furnishes NWPS Capital or its agent with
a  copy thereof; and (ii)  a United States Alien  Holder of a Preferred Security
will generally not be subject to United States federal income or withholding tax
on any gain realized upon the sale or other disposition of a Preferred Security,
except that a United States Alien Holder will be subject to United States income
tax on any gain if such United States Alien Holder (a) is engaged in a trade  or
business  in the  United States  and such gain  is effectively  connected to the
conduct of such trade or business or (b) is an individual present in the  United
States  for  183  days  or  more during  the  taxable  year,  and  certain other
conditions are met.

INFORMATION REPORTING TO HOLDERS

    Subject to  the  qualifications discussed  below,  income on  the  Preferred
Securities  will be  reported to  holders on Forms  1099, which  forms should be
mailed to holders of Preferred Securities by January 31 following each  calendar
year.

    NWPS  Capital will be obligated to report  annually to Cede & Co., as holder
of record of the Preferred Securities, the OID related to the Subordinated  Debt
Securities  that  accrued during  the year.  NWPS  Capital currently  intends to
report such information on Form 1099 prior to January 31 following each calendar
year. The Underwriters have indicated to  NWPS Capital that, to the extent  that
they  hold  Preferred  Securities  as  nominees  for  beneficial  holders,  they
currently expect to report to such  beneficial holders on Forms 1099 by  January
31  following  each  calendar  year. Under  current  law,  holders  of Preferred
Securities who  hold  as nominees  for  beneficial  holders will  not  have  any
obligation  to  report  information  regarding the  beneficial  holders  to NWPS
Capital. NWPS  Capital, moreover,  will not  have any  obligation to  report  to
beneficial  holders who are not also record holders. Thus, beneficial holders of
Preferred  Securities   who  hold   their  Preferred   Securities  through   the
Underwriters  will receive Forms  1099 reflecting the  income on their Preferred
Securities from such nominee holders rather than NWPS Capital.

BACKUP WITHHOLDING

    Payments made in respect  of, and proceeds from  the sale of, the  Preferred
Securities,  or  Subordinated  Debentures distributed  to  Holders  of Preferred
Securities, may  be subject  to a  "backup" withholding  tax of  31% unless  the
holder  complies with certain identification  requirements. Any withheld amounts
will be allowed as  a credit against the  holder's United States federal  income
tax, provided the required information is provided to the Service.

    THE  UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT  TO
THE TAX CONSEQUENCES TO THEM OF THE PURCHASE,

    Under  the terms and subject to the conditions contained in the Underwriting
Agreement dated the date hereof, each of the Underwriters named below, for  whom
Morgan  Stanley & Co.  Incorporated, Dean Witter  Reynolds Inc., NatWest Capital
Markets Limited, PaineWebber Incorporated and  Piper Jaffray Inc. are acting  as
representatives  (the "Representatives")  has severally agreed  to purchase, and
NWPS Capital has  agreed to  sell to each  of the  Underwriters, severally,  the
respective number of Preferred Securities set opposite its name below:

    Total.................................................................        1,200,000
                                                                                 ----------
                                                                                 ----------

    

    The  Underwriting  Agreement provides  that the  obligations of  the several
Underwriters to pay  for and  accept delivery  of the  Preferred Securities  are
subject to the approval of certain legal matters by their counsel and to certain
other  conditions. In the Underwriting  Agreement, the several Underwriters have
agreed, subject to the terms and  conditions set forth therein, to purchase  all
the  Preferred Securities offered hereby if  any of the Preferred Securities are
purchased. In the event of default by an Underwriter, the Underwriting Agreement
provides that,  in  certain  circumstances,  the  purchase  commitments  of  the
nondefaulting Underwriters may be increased or the Underwriting Agreement may be
terminated.

    The  Underwriters propose to  offer all or part  of the Preferred Securities
directly to the public  at the initial  public offering price  set forth on  the
cover  page of this Prospectus Supplement, and all or part to certain securities
dealers at a price  that represents a concession  not in excess  of $        per
Preferred  Security. The Underwriters may allow, and such dealers may reallow, a
concession not in  excess of $         per Preferred Security  to certain  other
dealers. After the Preferred Securities are released for sale to the public, the
offering  price and other selling  terms may from time to  time be varied by the
Representative.

   
    Because the proceeds of the sale of the Preferred Securities will ultimately
be used  to  purchase the  Subordinated  Debt  Securities of  the  Company,  the
Underwriting Agreement provides that the Company will pay to the Underwriters as
compensation  for their services $     per Preferred Security (or $       in the
aggregate); provided  that such  compensation will  be  $         per  Preferred
Security sold to certain institutions.
    

   
    During  a period  of 90  days from  the date  of the  Prospectus Supplement,
neither NWPS Capital nor the Company will, without the prior written consent  of
Morgan  Stanley & Co. Incorporated, directly or indirectly, sell, offer to sell,
grant any option for the sale of, pledge, or otherwise dispose of, any Preferred
Securities, any security  convertible into or  exchangeable into or  exercisable
for  Preferred Securities or any equity  securities substantially similar to the
Preferred Securities (except for any series of Subordinated Debt Securities  and
the  Preferred  Securities offered  hereby) or  enter into  any swap  or similar
agreement that transfers, in whole or in part, the economic risk of ownership of
Preferred Securities, whether any such transaction is to be settled by  delivery
of Preferred Securities or other securities, in cash or otherwise.
    

                                      S-32

   
    Application  has been made to list the  Preferred Securities on the New York
Stock Exchange. Listing will be contingent upon meeting the requirements of  the
New York Stock Exchange, including those relating to distribution. If listing is
approved,  trading of the Preferred Securities on the New York Stock Exchange is
expected to commence  within a 7-day  period after the  date of this  Prospectus
Supplement.  The Representatives have  advised NWPS Capital  that they intend to
make a market in the Preferred  Securities prior to the commencement of  trading
on  the New York Stock Exchange. The  Representatives will have no obligation to
make a market in the Preferred Securities, however, and may cease market  making
activities, if commenced, at any time.
    

    NWPS  Capital  and the  Company have  agreed  to indemnify  the Underwriters
against, or contribute to payments that the Underwriters may be required to make
in respect of, certain liabilities,  including liabilities under the  Securities
Act of 1933, as amended.

   
    Certain  of the  Underwriters engage  in (or  in the  future may  engage in)
transactions with, and  perform services  for, the  Company and  certain of  its
affiliates in the ordinary course of business. Morgan Stanley & Co. Incorporated
represents Synergy Group Incorporated in connection with the pending acquisition

                                  THE COMPANY

    The  Company's  principal business  is energy  distribution. The  Company is
engaged  as  an   electric  and   gas  utility   in  generating,   transmitting,
distributing,  and selling  electric energy  in eastern  South Dakota,  where it
furnishes electric service to  approximately 54,900 customers  in more than  100
communities  and adjacent rural areas  and in purchasing, distributing, selling,
and  transporting  natural  gas  to  approximately  75,000  customers  in   four
communities in Nebraska and 56 communities in eastern South Dakota. The Company,
through  its subsidiaries, is  also engaged in  certain nonutility operations as
more fully discussed under the caption "Nonutility Operations" and has  recently
contracted  to acquire Synergy Group  Incorporated, a major propane distribution
company. See "Pending  Acquisition of Synergy  Group Incorporated." The  Company
was  incorporated under the  laws of the State  of Delaware in  1923 and has its
principal office at  33 Third  Street SE,  Huron, South  Dakota 57350-1318.  Its
telephone number is 605-352-8411.

ELECTRIC BUSINESS

    On  a fully consolidated basis, 46% of the Company's 1994 operating revenues
were from the sale  of electric energy. All  of the Company's electric  revenues
are derived from customers in South Dakota.

   
    By customer category, 33% of 1994 total electric sales were from residential
sales,  50%  were  from commercial  and  industrial  sales, 2%  was  from street
lighting and sales to  public authorities, and 15%  were from sales for  resale.
The Company has relatively few large customers in its service territory.
    

    Sales  for resale  primarily include  power pool  sales to  other utilities.
Power pool sales fluctuate from  year to year depending  on a number of  factors
including  the Company's  availability of  excess short-term  generation and the
ability to sell  the excess  power to  other utilities  in the  power pool.  The
Company  also sells power and energy  at wholesale to certain municipalities for
resale and to various governmental agencies.

    The Company shares in the ownership of the Big Stone Generating Plant  ("Big
Stone"),  located near Big Stone City in northeastern South Dakota, the Coyote I
Electric Generating Plant ("Coyote"), located near Beulah, North Dakota, and the
Neal Electric Generating Unit #4 ("Neal"), located near Sioux City.

    At December  31, 1994,  the aggregate  net summer  peaking capacity  of  all
Company owned electric generating units was 309,480 kw, consisting of 105,711 kw
from Big Stone (the Company's 23.4% share),

                                       2

42,600  kw from  Coyote (the  Company's 10.0% share),  54,169 kw  from Neal (the
Company's 8.7% share), and 107,000 kw from internal combustion turbine units and
small diesel units, used primarily for peaking purposes.

    The Company is a summer peaking utility. The 1994 peak demand of 229,922  kw
occurred  on July  18, 1994.  Total system  capability at  the time  of peak was
309,480 kw. The  reserve margin  for 1994 was  35%. The  minimum reserve  margin
requirement  as determined by the members  of the Mid-Continent Area Power Pool,
of which the Company is a member, is 15%.

    The Company has  an integrated  resource plan to  identify how  to meet  the
energy needs of its customers. The plan includes estimates of customer usage and
programs  to provide for economic, reliable,  and timely supplies of energy. The
plan does not anticipate  the need for  additional baseload generating  capacity
for the Company for at least the next 10 years.

    All  of the Company's  baseload plants are  fueled by coal.  The Company has
maintained competitive electric rates when compared to neighboring utilities and
has a competitive electric baseload  generating production cost, which  includes
fuel  and plant operating  expenses, of less  than 1.5 CENTS  per kilowatt hour.
Lignite and  sub-bituminous  coal were  utilized  by  the Company  as  fuel  for
virtually  all  of  the electric  energy  generated during  1994.  The continued
delivery of lignite and sub-bituminous coal to the three large steam  generating
units  in which  the Company  is part owner  is reasonably  assured by contracts
covering various periods of the operating lives of these units.

GAS BUSINESS

    On a fully consolidated basis, 40% of the Company's 1994 operating  revenues
were  from the sale of  gas energy. During 1994, the  Company derived 56% of its
gas revenues from South Dakota and  44% from Nebraska. The Company's peak  daily
sendout was 128,700 MMBTU.

    For  the year ended December 1994, 44%  of the Company's gas sales were from
residential customers  and 56%  of  sales were  from commercial  and  industrial
sales.  During the last five years the Company has expanded its gas distribution
operations to serve 29 new communities in South Dakota.

    The Company  owns  and operates  natural  gas distribution  systems  serving
approximately  36,000 customers in eastern South  Dakota, for which it purchases
gas from various gas marketing firms under gas transportation service agreements
with various gas marketing firms. These agreements provide for firm  deliverable
pipeline  capacity of  approximately 49,300 MMBTU  per day in  South Dakota. The
Company has  service  agreements  with  Northern  Natural  Gas  Company  ("NNG")
providing  for  firm transportation  of natural  gas.  While NNG  has eliminated
nearly all of  its gas supply  activities, the Company  has supply contracts  in
place and peak shaving capacity to meet its peak day system needs.

    In  Nebraska, the Company owns and operates natural gas distribution systems
serving approximately 39,000  retail customers in  the village of  Alda and  the
cities  of  Grand  Island,  Kearney, and  North  Platte,  Nebraska.  The Company
purchases much of its natural gas for these systems from KN Gas Supply Co. under
a seven-year service agreement entered into in 1993. The Company also  purchases
certain  quantities of gas for its Nebraska customers from various gas marketing
firms. These  agreements  provide  for firm  deliverable  pipeline  capacity  of
approximately 49,600 MMBTU per day in Nebraska.

   
    To  supplement firm gas supplies, the  Company has contracts for underground
natural  gas  storage  services  to  meet  the  heating  season  and  peak   day
requirements  of its gas  customers. In addition, the  Company owns and operates
six propane-air plants with a total rated  capacity of 18,000 MMBTU per day,  or
approximately  14% of peak  day requirements. The  propane-air plants provide an
economic alternative  to pipeline  transportation charges  to meet  the  extreme
peaks caused by customer demand on extremely cold days.
    

    A  few  of the  Company's industrial  customers  purchase their  natural gas
requirements directly from gas marketing  firms for transportation and  delivery
through  the Company's distribution  system. The transportation  rates have been
designed to make the Company economically indifferent as to whether the  Company
sells and transports gas or only transports gas.

                                       3

COMPETITION

    Although  the Company's electric service  territory is assigned according to
the South Dakota Public Utilities Act, and the Company has the right to  provide
electric  service  to  present and  future  electric customers  in  its assigned
service area for so long as the service provided is deemed adequate, the  energy
industry  in general has become  increasingly competitive. Electric service also
competes with other forms of energy and the degree of competition may vary  from
time to time depending on relative costs and supplies of other forms of energy.

    The  National  Energy Policy  Act  of 1992  was  designed to  promote energy
efficiency and increased competition in the electric wholesale markets. Such Act
also allows the Federal Energy Regulatory Commission ("FERC") to order wholesale
wheeling by public utilities to provide utility and nonutility generators access
to public utility transmission facilitates. The FERC is currently  investigating
a  restructuring of  the electric  utility industry.  Many states  are currently
considering retail wheeling, which aims to provide all customers with the  right
to  choose their  electricity supplier.  No regulatory  proposals have  yet been
formally introduced in South Dakota.

    FERC Order 636  requires, among  other provisions, that  all companies  with
natural  gas pipelines separate  natural gas supply  or production services from
transportation service  and storage  businesses.  This allows  gas  distribution
companies,  such  as  the  Company, and  individual  customers  to  purchase gas
directly from producers, third parties,  and various gas marketing entities  and
transport  it through  the suppliers'  pipelines. While  Order 636  had positive
aspects by providing for  more diversified supply and  storage options, it  also
required   the   Company   to  assume   responsibility   for   the  procurement,
transportation, and storage of natural gas. The alternatives now available under
Order 636 create additional pressure on  all distribution companies to keep  gas
supply and transportation pricing competitive, particularly for large customers.

WEATHER

    Weather  fluctuations  in  the  Company's  service  area  have  the greatest
influence on the Company's revenues from year to year. Typically gas sales  peak
when  colder winter weather patterns create increased winter heating needs while
sales decline during warmer  winter periods. Electric  sales peak during  warmer
summer  periods  due to  increased air  conditioning  sales while  cooler summer
weather patterns produce less sales of electric energy.

REGULATION

    The Company is a  "public utility" within the  meaning of the Federal  Power
Act  and the South Dakota  Public Utilities Act and, as  such, is subject to the
jurisdiction of, and regulation by, FERC with respect to issuance of securities,
the South Dakota Public  Utilities Commission ("PUC")  with respect to  electric
service  territories, and both FERC and the  PUC with respect to rates, service,
accounting records,  and  in  other  respects. The  State  of  Nebraska  has  no
centralized   regulatory  agency  which  has  jurisdiction  over  the  Company's
operations in that state; however, the  Company's natural gas rates are  subject
to regulation by the municipalities in which it operates.

    Under  the South Dakota  Public Utilities Act, enacted  in 1975, a requested
rate increase may be implemented  by the Company 30 days  after the date of  its
filing  unless its effectiveness is suspended by the PUC and, in such event, can
be implemented subject  to refund  with interest six  months after  the date  of
filing,  unless  sooner  authorized  by the  PUC.  The  Company's  electric rate
schedules provide that it may pass  along to all classes of customers  qualified
increases  or decreases in the cost of  fuel used in its generating stations and
in the cost  of fuel  included in purchased  power. A  purchased gas  adjustment
provision  in its gas  rate schedules permits  the company to  pass along to gas
customers increases or decreases in the cost of purchased gas.

    The Company's last electric rate increase  amounted to less than 1% in  May,
1985.  On May 26, 1994,  the Company filed for a  $2.4 million increase in South
Dakota natural gas revenues. As a result of a negotiated settlement with the PUC
on  November  15,  1994,  the  Company  implemented  rates  which  will  produce
additional annual natural gas revenues of $2.1 million, assuming normal weather,
representing an overall

                                       4

   
increase  of 6.2%. On  December 30, 1994,  the Company filed  for a $2.7 million
increase in rates applicable to its Nebraska natural gas service area. Following
a  negotiated  settlement,  an  annual  increase  of  $2.275  million  has  been
implemented, effective July 1, 1995, an overall increase of 8.7%.
    

CAPITAL SPENDING AND FINANCING

    The  Company's  primary  capital  requirements include  the  funding  of its
utility construction and expansion programs,  the funding of debt and  preferred
stock  retirements  and  sinking  fund  requirements,  and  the  funding  of its
corporate development and investment activities.

    Expenditures for regulated utility  construction activities for 1994,  1993,
and  1992 were  $22.7 million,  $20.0 million,  and $18.5  million. Construction
expenditures during the last  three years included  expenditures related to  the
installation  of an additional 43 mw  of internal electric peaking capacity, the
expansion of the Company's natural gas system into 29 additional communities  in
eastern  South Dakota,  and to construction  of an operations  center which will
provide future cost savings and operating efficiencies through consolidation  of
activities.  Construction  expenditures  for  the  Company's  regulated  utility
businesses are estimated  to be  $19.3 million in  1995. The  majority of  these
projected  expenditures will  be spent on  enhancements of the  electric and gas
distribution  systems  and  completion  of  the  operations  center.   Estimated
construction expenditures for the Company's regulated utility businesses for the
years 1995 through 1999 are expected to be approximately $69 million.

    Capital  requirements for the mandatory retirement of long-term debt and the
mandatory preferred stock  sinking fund redemption  totaled $600,000,  $180,000,
and $513,000, for the years ended 1994, 1993, and 1992. It is expected that such
mandatory  retirements will be $600,000 in 1995, $1,080,000 in 1996, $570,000 in
1997, $20.6 million in 1998, and $13.5 million in 1999.

NONUTILITY OPERATIONS

   
    NORTHWESTERN GROWTH CORPORATION ("NGC"). NGC was incorporated under the laws
of South  Dakota  in  1994  to pursue  and  manage  nonutility  investments  and
development  activities. Although the primary  focus of NGC's investment program
will be to seek growth opportunities in the energy, energy equipment, and energy
services industries, NGC is also pursuing opportunities in existing and emerging
growth entities  in  nonenergy industries  that  meet return  and  capital  gain
requirements.  Along  with a  portfolio of  marketable securities,  NGC's assets
include the  investments of  three  subsidiaries: Northwestern  Networks,  Inc.,
Northwestern Systems, Inc., and SYN Inc.
    

    NORTHWESTERN NETWORKS, INC. ("NNI"). NNI was incorporated in South Dakota in
1986. NNI holds a common stock investment in LodgeNet Entertainment Corporation,
a  provider of  television entertainment and  information systems  to hotels and
motels.

    NORTHWESTERN SYSTEMS, INC. ("NSI"). NSI was incorporated in South Dakota  in
1986.  NSI owns all  of the common stock  ownership in Lucht,  Inc., a firm that
develops, manufactures, and markets multi-image photographic printers and  other
related equipment.

    SYN INC. ("SYN"). SYN, a Delaware corporation, was formed for the purpose of
acquiring  Synergy Group Incorporated, a major propane distributor. See "Pending
Acquisition of Synergy Group Incorporated."

    GRANT, INC.  Grant, Inc.,  which holds  title to  property not  used in  the
Company's utility business, was incorporated in South Dakota in 1972.

               PENDING ACQUISITION OF SYNERGY GROUP INCORPORATED

GENERAL

    On  May  17, 1995,  SYN  entered into  a  Purchase and  Sale  Agreement (the
"Acquisition Agreement") with Synergy Group Incorporated, a Delaware corporation
("Synergy"), S &  J Investments and  the stockholders of  Synergy (the  "Synergy
Stockholders"),  providing  for  the  acquisition  by  SYN  of  Synergy  and its

                                       5

subsidiaries and of certain operating  equipment which Synergy has been  leasing
from   S  &  J  Investments  (the  "Acquisition").  NGC,  the  immediate  parent
corporation of  SYN, joined  in  the Acquisition  Agreement to  guarantee  SYN's
performance thereof.

   
    Under  the terms of the Acquisition Agreement, the Acquisition is subject to
various  conditions   and  approvals,   including   the  accuracy   of   various
representations  and warranties made by the  sellers as to the business, assets,
financial condition and results of  operations of Synergy and its  subsidiaries,
the  obtaining of financing needed  by SYN for the  Acquisition, the issuance of
orders by the FERC authorizing the Company's issuance of the securities  offered
under  this Prospectus, the  net proceeds from  which are to  be used to provide
such  financing  for  SYN  (see  "Use  of  Proceeds"),  and  the  expiration  or
termination   of   the   waiting   period   for   the   Acquisition   under  the
Hart-Scott-Rodino Antitrust Improvements Act of 1976. On June 19, 1995 the  FERC
issued  the  required  orders and  on  July  6, 1995  early  termination  of the
Hart-Scott-Rodino waiting period was granted.
    

   
    The Acquisition will be  an expansion of  the Company's energy  distribution
business,  which  currently  is  primarily regulated  electric  and  gas utility
distribution. See "The Company". Two  of the Company's corporate objectives  are
intended  to be accomplished through the Acquisition. The immediate objective is
to expand the Company's energy distribution business. The second objective is to
use the business acquired from Synergy as a base for additional acquisitions  in
the  propane distribution industry which, unlike  the Company's electric and gas
public utility business, is not regulated  as to rates or territory served.  The
Company is currently considering the acquisition of a small propane distributor.
The  propane  distribution industry  currently  consists of  approximately 8,000
retail propane  marketing  companies  in the  continental  United  States,  with
propane  being the  fourth largest  source of energy  marketed at  retail in the
United States, following electricity, natural gas and fuel oil.
    

    As a result of  the factors affecting Synergy's  business, see "Business  of
Synergy", the Company expects that its consolidated revenues and earnings may be
subject to increased variability following consummation of the Acquisition.

BUSINESS OF SYNERGY

   
    Synergy,  headquartered in Farmingdale, New  York, is a multi-state marketer
principally engaged in the  retail distribution of propane  and other fuels  for
residential,  commercial,  industrial,  agricultural and  other  uses. Synergy's
propane sales during the past  three fiscal years represented approximately  83%
of its annual revenues, of which the major portion (approximately 50% of propane
sales in the fiscal year ending March 31, 1995) resulted from sales to customers
who  utilize propane for residential purposes, primarily for home heating, water
heating and cooking. The balance of propane sales are primarily for  commercial,
industrial  and agricultural use.  Synergy also sells propane  for use as engine
fuel for forklifts and over-the-road  vehicles. Synergy currently maintains  152
retail  branches  which service  approximately 200,000  customers in  23 states,
primarily in rural and suburban areas of the Northeast, Mid-Atlantic,  Southeast
and  Southcentral regions of the United  States. According to available industry
data, Synergy  is,  based upon  volume  sold, one  of  the nation's  10  largest
retailers of propane.
    

    Synergy  also sells gasoline,  diesel and aviation  fuel, and appliances and
equipment which use propane, and is engaged  in the sale, repair and leasing  of
forklift trucks.

   
    Synergy  purchases  propane from  major domestic  oil  companies as  well as
independent oil and liquid gas producers.  These producers ship the propane  via
pipeline to immediate supply terminals at which Synergy's large transport trucks
take  delivery and transport the propane  to bulk storage tanks. Synergy's fleet
of approximately 500 tank  trucks delivers the propane  from these bulk  storage
facilities  to approximately 193,000 propane storage tanks or cylinders which it
leases to its customers and which are located at customer premises. These  tanks
are  used exclusively to hold propane  purchased from Synergy, thereby promoting
the stability of Synergy's  customer base. While the  cost and inconvenience  of
switching  tanks tends to minimize switching by customers among suppliers on the
basis of minimal price variations, it also makes it more difficult to obtain new
customers, other than through  acquisitions, in areas  where there are  existing
relationships between potential customers and other distributors.
    

                                       6

    The  retail propane  industry is mature,  with only limited  growth in total
demand for the  product foreseen.  The Company  expects the  overall demand  for
propane  to  remain  relatively  constant  over  the  next  several  years, with
year-to-year industry  volumes being  impacted  primarily by  weather  patterns.
Therefore,  Synergy's ability to  grow within the industry  will be dependent on
its ability to acquire other retail distributors, on the success of opening  new
district  locations and on the  success of its marketing  efforts to acquire new
customers.

    Synergy competes with other distributors of propane, including several major
companies and several thousand small independent operators. Synergy's ability to
compete  effectively   depends  on   the  reliability   of  its   service,   its
responsiveness  to  customers and  its  ability to  maintain  competitive retail
prices.

   
    Synergy competes for  customers against suppliers  of electricity, fuel  oil
and  natural gas. In the last two decades,  many new homes were built, and older
homes converted to use electrical heating systems and appliances. Electricity is
a major  competitor  of propane,  but  propane generally  enjoys  a  substantial
competitive price advantage over electricity. The Company believes that fuel oil
does  not present a significant competitive  threat in Synergy's primary service
areas because:  (i)  propane is  a  residue-free, cleaner  energy  source,  (ii)
environmental concerns make fuel oil relatively unattractive, and (iii) fuel oil
appliances  generally are not  as efficient as  propane appliances. Furnaces and
appliances that  burn propane  will not  operate on  fuel oil,  and therefore  a
conversion  from  one  fuel  to  the  other  requires  the  installation  of new
equipment. Synergy's customers will have an incentive to switch to fuel oil only
if fuel oil becomes significantly less expensive than propane. Synergy generally
does not attempt  to sell propane  in areas served  by natural gas  distribution
systems,  except sales for specialized industrial applications because the price
per equivalent energy unit of propane is, and has historically been, higher than
that of natural  gas. To use  natural gas,  however, a retail  customer must  be
connected  to a distribution system provided by  a local utility. Natural gas is
not expected by management of the Company to create significant competition  for
Synergy  in  areas that  are not  currently served  by natural  gas distribution
systems because of the costs involved in building or connecting to a natural gas
distribution system.
    

   
    The propane  gas distribution  business is  affected by  economic and  other
factors,  some of which are  beyond the control of  the Synergy, such as weather
conditions. Synergy's business is highly seasonal, with a substantial portion of
its revenues  customarily being  generated during  the six  month winter  period
ending  in March.  Synergy's business was  adversely affected  by unusually warm
winter conditions in fiscal 1995. Warm  winter conditions in the future  periods
may  adversely affect Synergy's revenues, operating income and cash flow in such
years.
    

   
    The retail  propane business  is a  "margin-based" business  in which  gross
profits are dependent upon the excess of the sales price over the propane supply
costs.  Propane  is a  commodity, and,  as such,  its unit  price is  subject to
changes  in  response  to  changes   in  supply  or  other  market   conditions.
Consequently,  the unit price of propane purchased  by Synergy, as well as other
marketers, can change rapidly  over a short period.  In general, product  supply
contracts  permit suppliers to charge  posted prices at the  time of delivery or
the current prices established  at major storage points.  If rapid increases  in
the  wholesale  cost  of  propane  cannot be  immediately  passed  on  to retail
customers, such  increases may  reduce margins  on retail  sales.  Consequently,
Synergy's  profitability  will  be  sensitive to  changes  in  wholesale propane
prices.
    

   
    According to public reports  filed by Synergy  with the Commission,  Synergy
incurred  substantial net  losses in each  of its  last five fiscal  years. As a
result of such net losses, Synergy has been in default under certain of its debt
covenants and the  audit report  prepared by  Synergy's independent  accountants
relating  to Synergy's financial statements for  the last two fiscal years noted
that Synergy's  recurring losses  from operations,  net capital  deficiency  and
default  on  certain of  its debt  "raise substantial  doubt about  the entity's
ability to  continue as  a going  concern." Although  Synergy has  recorded  net
losses  during each of the  last five years, its  operating income for the years
ended March  31, 1995  and  1994 was  approximately $6,492,000  and  $4,090,000,
respectively.  See "Management  of Synergy" for  a description  of the Company's
financing  plans  and  anticipated  operating  efficiencies  which  the  Company
believes  will substantially  improve Synergy's results  of operations following
the Acquisition.

ACQUISITION CONSIDERATION

   
    The consideration to  be paid  by SYN for  the Acquisition,  in addition  to
assuming  various liabilities of  Synergy and its  subsidiaries, consists of (i)
cash in the amount of $137,500,000,  which amount will be subject to  adjustment
upward  or  downward according  to whether  the working  capital of  Synergy (as
specifically defined  in the  Acquisition  Agreement) exceeds  or is  less  than
$21,042,000  at the time of  closing of the Acquisition,  (ii) a promissory note
payable by SYN in the principal amount of $1,250,000, and (iii) the issuance  to
the  Synergy Stockholders of 17,500 shares of  the Common Stock of SYN (17.5% of
the total  that will  be  outstanding) and  2,500 shares  of  the 15%  Series  A
Cumulative  Preferred  Stock  of  SYN (valued  at  $2,500,000),  such  shares of
preferred stock being part of a series  of preferred stock of SYN for which  the
remaining 50,000 shares are expected to be issued to the Company in exchange for
a  $50,000,000 portion of  the long-term financing which  the Company expects to
provide to SYN. Substantially all of Synergy's loan indebtedness ($88.2 million)
will be paid from the cash portion of the consideration for the Acquisition.
    

MANAGEMENT OF SYNERGY

    The Acquisition  will be  made in  association with  Empire Gas  Corporation
("Empire  Gas"), a large propane  distribution company headquartered in Lebanon,
Missouri, which has a management experienced in the retail propane  distribution
business.  NGC and SYN have entered into a management agreement (the "Management
Agreement") with Empire Gas,  pursuant to which Empire  Gas has been engaged  to
perform the planning and management of the assets and business operations of SYN
and its subsidiaries, subject to the direction of the Board of Directors of SYN,
following the Acquisition (the "Management Services").

   
    It  is planned that,  immediately upon the  consummation of the Acquisition,
substantial changes will be made in the management and operation of the acquired
business in order  to achieve improvement  in the results  of operations of  the
business. NGC and Empire Gas will implement significant cost efficiency measures
to  reduce Synergy's operating, selling and general and administrative expenses.
These measures include the elimination of employee positions, corporate overhead
and  field  location  operating   expenses.  The  Synergy  headquarters   office
operations  will  be  consolidated  with the  Empire  Gas  corporate  offices in
Lebanon, Missouri, resulting in substantial expense savings. Another significant
portion  of  the  expense  reductions  is  represented  by  the  elimination  of
compensation   and  vehicle  lease  expenses  previously  paid  to  the  Synergy
Stockholders. In  addition  to operating  cost  reductions, the  Company's  post
acquisition  financing and capitalization  plan for Synergy  will reduce overall
financing expenses and provide capital for  growth that was not available  prior
to  the acquisition. See "Northwestern Public  Service Company and Synergy Group
Incorporated Pro Forma Financial Information."
    

   
    As compensation for the Management Services, SYN will pay Empire Gas a Fixed
Fee and  a Management  Fee.  The Fixed  Fee is  intended  to cover  Empire  Gas'
operating  overhead in performing the Management  Services and initially will be
$3,250,000 per annum, subject to adjustment annually based upon increases in the
Consumer Price Index. The  Management Fee will  be at the  rate of $500,000  per
annum  plus 10%  of the  amount by  which the  earnings before  interest, taxes,
depreciation and amortization  of SYN  and its subsidiaries,  on a  consolidated
basis, exceed certain threshold amounts.
    

    At  the time of the Acquisition, Empire  Gas will purchase 10% of the common
stock of SYN for $10,000 and will have an ongoing option to purchase from NGC an
additional 20% of the common stock of SYN for $20,000. However, according to the
formula stated in another agreement among SYN,  Empire Gas and NGC, NGC will  be
allowed  to reacquire from Empire Gas up to 7,500 shares of such common stock of
SYN, without payment, if Empire Gas fails to achieve certain cumulative  results
from  the management of SYN and  its subsidiaries while the Management Agreement
remains in effect.

   
    The term of the Management Agreement extends to June 30, 2000 and  continues
year  to year  thereafter unless  terminated earlier by  SYN or  Empire Gas. The
Management Agreement may be terminated by  either party prior to the  expiration
of  the  term on  any one  of several  grounds specified  in the  Agreement. The
Management Agreement includes  a right of  termination by SYN  if its  operating
results do not exceed prescribed thresholds which increase annually as specified
therein. In the event the Company receives notice
    

                                       8

   
that  the Management  Agreement will  be terminated by  Empire Gas,  SYN has the
right to the use of the personnel and  facilities of Empire Gas for a period  of
up  to  18 months  following  such notice  by  Empire Gas,  while  developing an
alternative for Empire Gas' services.
    

   
THIRD PARTY SALE
    

   
    NGC and SYN have entered into a purchase agreement with an unrelated  party,
granting  that party the right to purchase  certain of the retail branches to be
acquired by SYN from Synergy (the "Third Party Sale"). The third party  purchase
must  occur immediately  after the closing  of the Acquisition  and the purchase
price is payable in cash and will be  based on the price paid by SYN to  Synergy
for  such outlets. Such cash price is estimated to be approximately $40 million,
which would decrease  SYN's cash  payment for the  Acquisition to  approximately
$100  million,  which  reduction  would  be  applied  to  reduce  the  long-term
investment in securities to be issued by SYN to NGC or the Company and the  loan
to be made by NGC to SYN.
    

CAPITALIZATION OF SYN

   
    The  capitalization of SYN, taking into account the financing intended to be
provided to SYN by the Company and NGC  from the net proceeds of certain of  the
securities being offered pursuant to this Prospectus (see "Use of Proceeds"), is
planned  to  be as  follows at  the  time of  the Acquisition  closing, assuming
consummation of the third party sale:

    Set forth  below  are summary  financial  data extracted  from  the  audited
consolidated  statement of operations of the Company for the year ended December
31, 1994, the unaudited consolidated financial  statements of the Company as  of
March  31, 1995, and for the three months then ended; the summary financial data
extracted from  the unaudited  statement of  operations of  Synergy for  the  12
months  ended December 31, 1994  and for the three  months ended March 31, 1995,
and balance sheet information as of March 31, 1995; and the pro forma  financial
information for the Company ("the Pro Forma Financial Information") for the year
ended  December 31, 1994, for  the three months ended March  31, 1995, and as of
March 31, 1995, based on such historical financial statements, to illustrate the
effects of the Acquisition. The Pro Forma Financial Information illustrates  the
effects  of the Acquisition as adjusted to  give effect to the Third Party Sale.
(See "Pending Acquisition of Synergy Group Incorporated.")
    
   
    The  Acquisition  will  be  accounted  for  using  the  purchase  method  of
accounting.  After the Acquisition, the total  purchase price of the Acquisition
will be allocated to  Synergy's tangible and  intangible assets and  liabilities
based  upon  their  respective  fair values.  The  allocation  of  the aggregate
purchase price included in the  Pro Forma Financial Information is  preliminary,
but  the  final allocation  of  the purchase  price  is not  expected  to differ
materially from the preliminary  allocation. The financing  plan to be  executed
for  the funding of  the Acquisition is expected  to be as  presented in the Pro
Forma Financial  Information.  Although  market conditions  may  impact  certain
financing options and assumptions as to interest and dividend rates, the overall
financing plan is not expected to vary materially from that presented.
    
   
    The  pro forma statements of operations for the year ended December 31, 1994
and for the three months ended March  31, 1995, give effect to the  Acquisition,
and the related transactions as if they had occurred on January 1, 1994. The pro
forma balance sheet as of March 31, 1995 has been prepared as if the transaction
had  occurred on that date. The pro forma financial information does not purport
to present the financial  position or results of  operations of the Company  had
the  Acquisition actually been completed as of the dates indicated. In addition,
the pro  forma financial  information is  not necessarily  indicative of  future
results  of operations  and should  be read  in conjunction  with the historical
consolidated financial  statements  of  the Company  incorporated  by  reference
herein.

                    NOTES TO PRO FORMA FINANCIAL INFORMATION

   
A) Represents all relevant statement of operations effects, net of income taxes,
    generated by the expected sale of certain Synergy properties to an unrelated
    third party. Although a  purchase agreement to  sell certain properties  has
    been   executed  and  it  is  anticipated  that  such  transaction  will  be
    consummated, in the event the Third Party Sale is not closed, pro forma  net
    income available for common would have been $15,343,000 and $14,040,000; and
    pro  forma net income per  common share would have  been $1.73 and $1.58 for
    the year ended December 31,  1994 and for the  three months ended March  31,
    1995,  respectively. The  following represents  the estimated  impact on pro
    forma net income  available for  common as presented  if the  sale does  not
    occur (in thousands):

    All  general and  administrative functions  previously performed  at Synergy
    headquarters would  be undertaken  by Empire  Gas, Inc.  under a  management
    agreement  governing the operation of  the Synergy properties. (See "Pending
    Acquisition  of  Synergy  Group  Incorporated.")  Under  the  terms  of  the
    management  agreement, Empire Gas will be  compensated through a general and
    administrative charge and a management fee arrangement.

   
    The vehicle lease expenses are  primarily attributable to property owned  by
    affiliates of existing Synergy shareholders. Such property will be purchased
    as  a part of the acquisition transaction. The increase in lease expense for
    the three  months  ended March  31,  1995 reflects  the  net effect  of  the
    elimination  of such lease expense  and a reversal of  the credit to expense
    created by  a $1,328,000  forgiveness by  these same  affiliates of  accrued
    rental  obligations. In addition, general and administrative expense savings
    include shareholder compensation.
    

C) Represents  additional  depreciation and  amortization  of fixed  assets  and
    intangibles  related to  the adjustment  of assets  to fair  market value in

D) Represents  interest  expense  savings  associated  with  the  retirement  of
    Synergy's  debt as  a result of  the Acquisition net  of additional interest
    expense related to NPS issuing new debt securities.

    compensation  adjustment not been  made, pro forma  net income available for
    common would have  been $8,973,000; pro  forma net income  per common  share
    would  been $1.02; ratio of earnings to  fixed charges would have been 4.38x
    and ratio of earnings to fixed charges, including preferred dividends  would
    have been 3.68x for the three months ended March 31, 1995.

                                THE NWPS TRUSTS

    Each of NWPS Capital Financing I, NWPS Capital Financing II and NWPS Capital
Financing  III is a statutory business  trust formed under Delaware law pursuant
to (i) a separate declaration of trust ( each, a "Declaration") executed by  the
Company,  as sponsor for such  trust (the "Sponsor"), and  the NWPS Trustees (as
defined below) of such trust  and (ii) the filing  of a separate certificate  of
trust  with the Secretary  of State of the  State of Delaware  on June 19, 1995.
Each NWPS Trust exists for the  exclusive purposes of (i) issuing the  Preferred
Securities  and common securities representing undivided beneficial interests in
the assets of such  NWPS Trust (the "Common  Securities" and, together with  the
Preferred Securities, the "Trust Securities"), (ii) investing the gross proceeds
from the sale of the Trust Securities in the Subordinated Debt Securities of the
Company  and  (iii)  engaging  in  only  those  other  activities  necessary  or
incidental thereto. All of the Common Securities will be directly or  indirectly
owned  by the Company. The Common Securities  will rank pari passu, and payments
will be made thereon pro rata, with the Preferred Securities, except that,  upon
an  event of  default under the  Declaration, the  rights of the  holders of the
Common Securities  to payment  in  respect of  distributions and  payments  upon
liquidation,  redemption and otherwise will be subordinated to the rights of the
holders of the  Preferred Securities.  The Company will  directly or  indirectly
acquire  Common Securities in an aggregate liquidation amount equal to 3% of the
total capital of each NWPS Trust. Each NWPS Trust has a term of approximately 55
years but may terminate earlier, as  provided in each Declaration. The  business
and  affairs of  each NWPS Trust  will be  conducted by the  trustees (the "NWPS
Trustees") appointed by the Company as the direct or indirect holder of all  the
Common  Securities.  The holder  of the  Common Securities  will be  entitled to
appoint, remove or replace any of, or increase or reduce the number of, the NWPS
Trustees of a NWPS Trust.  The duties and obligations  of the NWPS Trustees  for
each  NWPS Trust shall be governed by the Declaration for such trust. A majority
of the NWPS Trustees will be persons who are employees or officers of or who are
affiliated with  the  Company  (the  "Regular  Trustees").  In  certain  limited
circumstances   set  forth  in  the  Prospectus  Supplement  for  the  Preferred
Securities, the holders  of a majority  in liquidation amount  of the  Preferred
Securities  will be entitled to appoint  one additional Regular Trustee who need
not be an employee or officer of  or otherwise affiliated with the Company.  One
NWPS  Trustee of  each NWPS Trust  will be  a financial institution  that is not
affiliated with the  Company and  has a  specified minimum  amount of  aggregate
capital,  surplus, and  undivided profits  of not  less than  $50,000,000, which
shall act as property trustee and as  indenture trustee for the purposes of  the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), pursuant to
the  terms set forth  in the Prospectus Supplement  for the Preferred Securities
(the "Property Trustee"). In addition,  unless the Property Trustee maintains  a
principal  place of business  in the State  of Delaware and  otherwise meets the
requirements of applicable law, one NWPS Trustee of each NWPS Trust will have  a
principal  place of business or  reside in the State  of Delaware (the "Delaware
Trustee"). The Company will pay all fees and expenses related to the NWPS Trusts
and the  offering  of  the  Trust  Securities, the  payment  of  which  will  be
guaranteed  by the  Company as described  under "Description  of the Guarantees"
herein. The Delaware Trustee  for each NWPS Trust  is Wilmington Trust  Company,
Rodney  Square North, 1100 North Market  Street, Wilmington, Delaware 19890. The
principal place of  business of each  NWPS Trust  is c/o the  Company, 33  Third
Street S.E., Huron, South Dakota, 57350-1318, telephone (605) 352-8411.

                                       19

                                USE OF PROCEEDS

   
    If  the Third Party Sale  is consummated, the net  proceeds from the sale of
$102.5  million  of  the  Offered  Securities  will  be  applied  to  fund   the
Acquisition,  including certain transaction  expenses. The Company  will use $50
million of  the net  proceeds to  purchase 50,000  shares of  the 15%  Series  A
Cumulative  Preferred  Stock of  SYN, the  subsidiary of  the Company  formed to
effect the Acquisition, and $52.5 million of the net proceeds will be loaned  by
the Company to SYN. If the Third Party Sale is not consummated, the net proceeds
from  the sale of $142,500,000 of the Offered Securities will be applied to fund
the Acquisition,  including  certain  transaction expenses.  In  that  case  the
Company  will use $68 million  of the net proceeds  to purchase 68,000 shares of
the 15% Series A Cumulative Preferred Stock of SYN and $74.5 million of the  net
proceeds will be loaned by NGC to SYN.
    

    Each  NWPS Trust will use all of the  proceeds received from the sale of its
Preferred Securities to purchase Subordinated Debt Securities from the  Company.
The  Company intends to add  the net proceeds from  the sale of the Subordinated
Debt Securities to its  general funds, to  be used to  fund the Acquisition,  as
described above, and for other general corporate purposes, as described below.

   
    The  net proceeds from the sale of any other Offered Securities will be used
for general corporate purposes, which may include the repayment of indebtedness,
working capital  expenditures  and other  investments  in, or  acquisitions  of,
businesses  and assets.  Pending application of  such net  proceeds for specific
purposes, such proceeds may be invested in short-term or marketable  securities.
Specific  allocations of proceeds to a particular purpose that have been made at
the date of any Prospectus Supplement will be described therein.
    

   
    In the event the Acquisition is  not consummated, the net proceeds from  the
sale  of the  Offered Securities will  be used  to redeem or  acquire and retire
outstanding First Mortgage Bonds (as defined under "Description of the  Mortgage
Bonds"),  repay short  term debt, and  for other general  corporate purposes, as
described above.
    

                RATIO OF EARNINGS TO FIXED CHARGES AND EARNINGS
               TO COMBINED FIXED CHARGES AND PREFERRED DIVIDENDS

    The following table sets forth the  ratios of earnings to fixed charges  and
earnings to combined fixed charges and preferred dividends for the Company on an
historical  basis for the fiscal years ended December 31, 1994, 1993, 1992, 1991
and 1990, and for the three-month period  ended March 31, 1995. Such ratios  are
also presented on a pro forma basis for the year ended December 31, 1994 and the
three-month  period ended  March 31, 1995.  For the purpose  of calculating such
ratios, "earnings" consist  of income from  continuing operations before  income
taxes,  "fixed charges" consist of interest on all indebtedness, amortization of
debt expense and  the percentage of  rental expense on  operating leases  deemed
representative  of  the  interest  factor  and  "preferred  dividends" represent
dividends paid  on all  preferred  shares outstanding  during the  periods.  See
"Northwestern  Public Service Company  and Synergy Group  Incorporated Pro Forma
Financial Information" for the assumptions upon  which the pro forma ratios  are
based.

                       DESCRIPTION OF THE MORTGAGE BONDS

GENERAL

    The  Mortgage Bonds will be bonds,  notes or other evidences of indebtedness
authenticated and  delivered under  a  General Mortgage  Indenture and  Deed  of
Trust, between the Company and The Chase

                                       20

   
Manhattan  Bank (N.A.) (the "New Mortgage Trustee"), dated as of August 1, 1993.
The New Mortgage Trustee shall act as indenture trustee for the purposes of  the
Trust  Indenture Act  of 1939,  as amended.  Such General  Mortgage and  Deed of
Trust, as supplemented by various supplemental indentures, including one or more
supplemental indentures relating to the Mortgage Bonds, is hereinafter  referred
to  as the "New Mortgage." The summaries under this heading do not purport to be
complete and  are  subject to  the  detailed  provisions of  the  New  Mortgage.
Capitalized  terms used  under this heading  which are not  otherwise defined in
this Prospectus shall have  the meanings ascribed thereto  in the New  Mortgage.
Wherever  particular provisions of the New Mortgage or terms defined therein are
referred to, such provisions or definitions  are incorporated by reference as  a
part  of the statements made  herein and such statements  are qualified in their
entirety by such reference.  References to article and  section numbers in  this
description of the Mortgage Bonds, unless otherwise indicated, are references to
article and section numbers of the New Mortgage.
    

    The  New Mortgage provides that additional bonds may be issued thereunder on
the basis of Pledged Bonds (as hereinafter defined), property additions, retired
bonds and  cash.  (See  "Issuance  of Additional  Mortgage  Bonds"  below.)  The
Mortgage  Bonds and all other bonds heretofore or hereafter issued under the New
Mortgage are collectively referred to herein as the "Mortgage Bonds."

    Reference is made to the Prospectus Supplement for the Mortgage Bonds for  a
description of the following terms of the series of Mortgage Bonds in respect of
which  this Prospectus is being delivered: (i) the title (series designation) of
such Mortgage Bonds; (ii) the limit, if any, upon the aggregate principal amount
of such Mortgage Bonds, (iii) the date  or dates on which the principal of  such
Mortgage  Bonds is payable; (iv) the rate  or rates at which such Mortgage Bonds
will bear interest,  if any; the  date or  dates from which  such interest  will
accrue;  the dates  on which  such interest  will be  payable ("Interest Payment
Dates") and the regular record dates  for the interest payable on such  Interest
Payment  Dates; (v) the bases  on which the Mortgage  Bonds will be issued; (vi)
the option, if any, of the Company to redeem such Mortgage Bonds and the periods
within which  or the  dates on  which, the  prices at  which and  the terms  and
conditions upon which, such Mortgage Bonds may be redeemed, in whole or in part,
upon  the exercise of such option; (vii)  the obligation, if any, of the Company
to redeem  or purchase  such Mortgage  Bonds  pursuant to  any sinking  fund  or
analogous provisions or at the option of the Holder and the periods within which
or  the dates on  which, the prices at  which and the  terms and conditions upon
which such Mortgage Bonds  will be redeemed,  in whole or  in part, pursuant  to
such  obligation; (viii) the denominations in  which such Mortgage Bonds will be
issuable; and (ix) any other terms of such Mortgage Bonds not inconsistent  with
the provisions of the New Mortgage.

    While  the  New  Mortgage contains  provisions  for the  maintenance  of the
Mortgaged Property, it  does not  contain any  provisions for  a maintenance  or
sinking  fund and, except  as may be  provided in a  Supplemental Indenture (and
described in the applicable Prospectus Supplement), there will be no  provisions
for any such funds for the Mortgage Bonds.

REDEMPTION OF THE MORTGAGE BONDS

    Any terms for the optional or mandatory redemption of Mortgage Bonds will be
set forth in the Prospectus Supplement. Except as shall otherwise be provided in
the  applicable Prospectus Supplement with  respect to Mortgage Bonds redeemable
at the option of the Holder, Mortgage Bonds will be redeemable only upon  notice
by  mail not less than 30  days prior to the date  fixed for redemption, and, if
less than all the Mortgage Bonds of a series, or any tranche thereof, are to  be
redeemed,  the particular Mortgage Bonds to be redeemed will be selected by such
method as shall  be provided for  the particular  series or tranche,  or in  the
absence  of any such provision, by such  method as the Bond Registrar deems fair
and appropriate. (See Sections 5.03 and 5.04.)

    Any notice of redemption at  the option of the  Company may state that  such
redemption  shall be conditioned upon receipt by the New Mortgage Trustee, on or
prior to the dated  fixed for such  redemption, of money  sufficient to pay  the
principal  of and premium, if any, and  interest, if any, on such Mortgage Bonds
and that if such money has not been so received, such notice will be of no force
and effect and the Company will not  be required to redeem such Mortgage  Bonds.
(See Section 5.04.)

                                       21

SECURITY

    GENERAL.   Except as discussed below, Mortgage Bonds now or hereafter issued
under the New Mortgage will be secured primarily by:

        (a) bonds ("First Mortgage Bonds") issued under the Company's  Indenture
    dated  August 1,  1940 (the "First  Mortgage"), to The  Chase Manhattan Bank
    (National Association), successor by  merger to The  Chase National Bank  of
    the  City of New York, as trustee  (the "First Mortgage Trustee"), and C. J.
    Heinzelmann, successor  to  Carl  E. Buckley,  as  individual  trustee,  and
    delivered  to the New  Mortgage Trustee under the  New Mortgage, which First
    Mortgage Bonds will  be secured, equally  and ratably with  all other  bonds
    issued  under the First Mortgage, by a valid first lien on substantially all
    of the fixed property, franchises and  rights of the Company of a  character
    not  expressly  excepted from  the  lien (which  excepted  property consists
    principally of  cash, securities,  receivables, personal  property held  for
    sale  or lease or consumable in operations, and certain real estate held for
    resale and  not  used  or useful  in  the  public utility  business  of  the
    Company),  subject to  permitted encumbrances  and liens  as defined  in the
    First Mortgage; and

        (b) the lien of the New Mortgage on the Company's properties used in the
    generation, production, transmission or  distribution of electricity or  the
    distribution  of gas in any form and for  any purpose in the States of South
    Dakota or Nebraska, together with the properties owned by the Company as  of
    August  1, 1993 located in the States of North Dakota and Iowa which consist
    principally of shared ownership interests in electric generating  facilities
    (the  Company does  not serve  customers in the  States of  North Dakota and
    Iowa), but not,  unless the  Company otherwise elects,  any future  acquired
    properties  in the States of North Dakota  and Iowa, which lien is junior to
    the lien of the First Mortgage.

    As  discussed  below   under  "Pledged   Bonds,"  following   a  merger   or
consolidation of another corporation into the Company, the Company could deliver
to  the New  Mortgage Trustee  bonds issued  under an  existing mortgage  on the
properties of such other corporation in lieu  of or in addition to bonds  issued
under  the First Mortgage. In  such event, the Mortgage  Bonds would be secured,
additionally, by  such  bonds  and by  the  lien  of the  New  Mortgage  on  the
properties of such other corporation, which would be junior to the liens of such
existing  mortgage and the First Mortgage. The First Mortgage and all such other
mortgages are hereinafter, collectively, called  the "Class "A" Mortgages,"  and
all bonds issued under the Class "A" Mortgages and delivered to the New Mortgage
Trustee  are hereinafter collectively called the "Pledged Bonds." If and when no
Class "A" Mortgages  are in  effect, the New  Mortgage will  constitute a  first
mortgage lien on all property of the Company subject thereto.

    PLEDGED  BONDS.   The Pledged  Bonds will  be issued  and delivered  to, and
registered in the name of, the New  Mortgage Trustee or its nominee and will  be
owned and held by the New Mortgage Trustee, subject to the provisions of the New
Mortgage,  for the benefit of the Holders of all Mortgage Bonds Outstanding from
time to time,  and the  Company will  have no  interest in  such Pledged  Bonds.
Except  as may be otherwise set forth  in the supplemental indenture pursuant to
which any Mortgage Bonds are to be issued, Pledged Bonds issued as the basis for
the authentication and delivery  of such Mortgage Bonds  (a) will mature on  the
same  dates, and in the same principal  amounts, as such Mortgage Bonds, and (b)
will contain, in addition to  any mandatory redemption provisions applicable  to
all  Pledged Bonds Outstanding  under the related  Class "A" Mortgage, mandatory
redemption provisions correlative to provisions for mandatory redemption, or for
redemption at the option  of the Holder, of  such Mortgage Bonds. Pledged  Bonds
issued  as the basis for  authentication and delivery of  a series or tranche of
Mortgage Bonds (x) may,  but need not,  bear interest, any  such interest to  be
payable  at the same times  as interest on the Mortgage  Bonds of such series or
tranche, and  (y) may,  but  need not,  contain  provisions for  the  redemption
thereof  at the  option of  the Company,  any such  redemption to  be made  at a
redemption price or prices  not less than the  principal amount of such  Pledged
Bonds. (See Sections 4.02 and 7.01.)

    Any  payment by the  Company of principal  of or premium  or interest on the
Pledged Bonds  held by  the New  Mortgage Trustee  will be  applied by  the  New
Mortgage  Trustee to the payment  of any principal, premium  or interest, as the
case may be, in  respect of the Mortgage  Bonds which is then  due, and, to  the
extent of such application, the obligation of the Company under the New Mortgage
to make such payment in

                                       22

respect  of the Mortgage Bonds  will be deemed satisfied  and discharged. If, at
the time of any such  payment of principal of Pledged  Bonds, there shall be  no
principal  then  due in  respect to  the  Mortgage Bonds,  the proceeds  of such
payment will be deemed  to constitute Funded  Cash and will be  held by the  New
Mortgage Trustee as part of the New Mortgaged Property, to be withdrawn, used or
applied  as provided in the New Mortgage. If, at the time of any such payment of
premium or interest on Pledged Bonds, there shall be no premium or interest,  as
the case may be, then due in respect of the Mortgage Bonds, the proceeds of such
payment  will be remitted to  the Company at its  request. (See Section 7.02 and
"Withdrawal of  Cash" below.)  Any payment  by the  Company of  principal of  or
premium  or interest on Mortgage Bonds  authenticated and delivered on the basis
of the deposit with  the New Mortgage  Trustee of Pledged  Bonds (other than  by
application  of the  proceeds in  respect of  such Pledged  Bonds) will,  to the
extent thereof,  be  deemed to  satisfy  and  discharge the  obligation  of  the
Company,  if any, to  make a payment  of principal, premium  or interest, as the
case may be, in respect of such Pledged Bonds which is then due.

    The New Mortgage  Trustee may  not sell,  assign or  otherwise transfer  any
Pledged Bonds except to a successor trustee under the New Mortgage. (See Section
7.04.)  At the time any Mortgage Bonds of  any series or tranche which have been
authenticated and  delivered  upon  the  basis of  Pledged  Bonds  cease  to  be
Outstanding  (other than as a  result of the application  of the proceeds of the
payment or redemption  of such Pledged  Bonds), the New  Mortgage Trustee  shall
surrender  to or upon the order of the Company an equal principal amount of such
Pledged  Bonds  having  the  same  Stated  Maturity  and  mandatory   redemption
provisions as such Mortgage Bonds. (See Section 7.03.)

    At  the date of  this Prospectus, the  only Class "A"  Mortgage is the First
Mortgage and the  only Pledged Bonds  issuable at this  time are First  Mortgage
Bonds  issuable thereunder. The New  Mortgage provides that in  the event of the
merger or consolidation of another company with or into the Company, an existing
mortgage constituting a lien  on properties of such  other company prior to  the
lien of the New Mortgage may be designated by the Company as an additional Class
"A"  Mortgage. Bonds thereafter  issued under such  additional mortgage would be
Pledged Bonds and could provide the basis for the authentication and delivery of
Mortgage Bonds under the New Mortgage. (See Section 7.06.) When no Pledged Bonds
are Outstanding under a Class "A" Mortgage except for Pledged Bonds held by  the
New  Mortgage  Trustee, then,  at  the request  of  the Company  and  subject to
satisfaction of certain conditions, the New Mortgage Trustee will surrender such
Pledged Bonds  for cancellation,  and the  related Class  "A" Mortgage  will  be
satisfied  and discharged, the lien of such  Class "A" Mortgage on the Company's
property will cease to exist  and the priority of the  lien of the New  Mortgage
will be increased. (See Section 7.07.)

   
    The  New Mortgage  contains no restrictions  on the issuance  of bonds under
Class "A" Mortgages  in addition  to Pledged Bonds  issued to  the New  Mortgage
Trustee  as the  basis for  the authentication  and delivery  of Mortgage Bonds.
First Mortgage Bonds  may currently be  issued under the  First Mortgage on  the
basis  of property additions,  retirements of bonds  previously issued under the
First Mortgage and cash  deposited with the First  Mortgage Trustee. As of  July
27,  1995, $47,500,000 of  First Mortgage Bonds (other  than Pledged Bonds) were
outstanding.
    

    LIEN OF  THE NEW  MORTGAGE.   The  properties of  the  Company used  in  the
generation,  production, transmission  and distribution  of electricity  and the
distribution of gas  in any  form and  for any purpose  in the  States of  South
Dakota or Nebraska together with properties owned by the Company as of August 1,
1993 located in the States of North Dakota and Iowa (but not, unless the Company
otherwise  elects, any future acquired properties  in the States of North Dakota
and Iowa) are subject to the lien of the New Mortgage. Substantially all of such
property, while subject to the lien of the New Mortgage, will be also subject to
the prior lien of the First Mortgage.  The Mortgage Bonds will have the  benefit
of the prior lien of the First Mortgage on such property, and the benefit of the
prior lien of any additional Class "A" Mortgage on any property subject thereto,
to  the extent of the aggregate principal  amount of Pledged Bonds, issued under
the respective Class "A" Mortgages, held by the New Mortgage Trustee.

    The lien of the New Mortgage is subject to Permitted Liens which include tax
liens and other  governmental charges  which are  not delinquent  and which  are
being  contested, construction and materialmen's  liens, certain judgment liens,
easements, reservations and rights  of others (including governmental  entities)

                                       23

in,  and defects of title in, certain property of the Company, certain leasehold
interests, liens on the Company's pollution  control and sewage and solid  waste
facilities and certain other liens and encumbrances. (See Section 1.01.)

    There  are excepted from the  lien of the New  Mortgage, among other things,
cash and securities  not paid to,  deposited with  or held by  the New  Mortgage
Trustee  under the New  Mortgage; contracts, leases and  other agreements of all
kinds, contract rights, bills, notes and other instruments, accounts receivable,
claims, certain  intellectual property  rights  and other  general  intangibles;
permits,   licenses  and   franchises;  automobiles,   other  vehicles,  movable
equipment, aircraft and vessels; all goods, wares and merchandise held for  sale
in  the ordinary  course of business  or for  use by or  for the  benefit of the
Company; fuel, materials, supplies and other personal property consumable in the
operations of the Company's business; computers, machinery and equipment;  coal,
ore,  gas,  oil, minerals  and  timber mined  or  extracted from  the  land; gas
transmission lines connecting  wells with main  or branch trunk  lines or  field
gathering  lines  connecting wells  with main  or  branch trunk  lines; electric
energy, gas, steam, water and  other products generated, produced or  purchased;
leasehold  interests; and  all books  and records.  (See Granting  Clauses.) The
First Mortgage contains similar, but not identical, exceptions.

    Without the consent of the Holders, the Company and the New Mortgage Trustee
may enter  into  supplemental indentures  to  subject to  the  lien of  the  New
Mortgage additional property, whether or not used in the electric or gas utility
businesses  (including  property which  would  otherwise be  excepted  from such
lien). (See Section 14.01.) Such property,  so long as the same would  otherwise
constitute  Property Additions (as described  below), would thereupon constitute
Property Additions and  be available  as a basis  for the  issuance of  Mortgage
Bonds. (See "Issuance of Additional Mortgage Bonds" below.)

    The  New Mortgage contains provisions  subjecting after-acquired property to
the lien  thereof,  subject to  the  prior lien  of  the First  Mortgage.  These
provisions  are limited in the  case of consolidation or  merger (whether or not
the Company is the  surviving corporation) or sale  of substantially all of  the
Company's assets. In the event of consolidation or merger or the transfer of all
the mortgaged property as or substantially as an entirety, the New Mortgage will
not be required to be a lien upon any of the properties then owned or thereafter
acquired  by  the successor  corporation,  except properties  acquired  from the
Company in or as a result  of such transaction and improvements, extensions  and
additions  to such properties and renewals, replacements and substitutions of or
for  any  part  or  parts  of   such  properties.  (See  Article  Thirteen   and
"Consolidation,  Merger,  Conveyance, Transfer  or  Lease" below.)  In addition,
after-acquired property  may  be  subject  to  vendors'  liens,  purchase  money
mortgages  and other liens thereon at the time of acquisition thereof, including
the lien of any Class "A" Mortgage.

    The New Mortgage provides  that the New Mortgage  Trustee will have a  lien,
prior  to the lien  on behalf of  the holders of  Mortgage Bonds, upon Mortgaged
Property and any money collected by the New Mortgage Trustee as proceeds of  the
Mortgaged  Property, for the payment of its reasonable compensation and expenses
and for indemnity against certain liabilities. (See Section 11.07.)

ISSUANCE OF ADDITIONAL MORTGAGE BONDS

    The maximum principal amount of Mortgage Bonds which may be issued under the
New Mortgage is limited to $500,000,000,  provided that, without the consent  of
the   Holders,  the  Company  and  the  New  Mortgage  Trustee  may  enter  into
supplemental indentures to increase such amount. (See Sections 3.01 and  14.01.)
Mortgage  Bonds of any series may be issued from time to time under Article Four
of the New Mortgage on  the basis of, and in  an aggregate principal amount  not
exceeding:

        (1) the aggregate principal amount of Pledged Bonds issued and delivered
    to the Trustee;

        (2)  75%  of the  Cost or  Fair  Value (whichever  is less)  of Property
    Additions (as  described  below) which  do  not constitute  Bonded  Property
    Additions  (being, generally,  Property Additions  which have  been made the
    basis of the authentication and delivery  of Mortgage Bonds, the release  of
    mortgaged  property  or  cash  withdrawals)  after  certain  deductions  and
    additions, primarily including adjustments to offset property retirements;

                                       24

        (3) the aggregate principal  amount of Retired  Bonds (which consist  of
    Mortgage  Bonds  no longer  Outstanding  under the  New  Mortgage (including
    Mortgage Bonds deposited under  any sinking or  analogous funds) which  have
    not  been used for certain  other purposes under the  New Mortgage and which
    are not to  be paid,  redeemed or otherwise  retired by  the application  of
    Funded  Cash),  but  if Pledged  Bonds  have  been made  the  basis  for the
    authentication and delivery of such Retired Bonds, only if the related Class
    "A" Mortgage has been discharged; and

        (4) an amount of cash deposited with the Trustee.

    In general,  the issuance  of  Mortgage Bonds  is  subject to  Adjusted  New
Earnings of the Company for 12 consecutive months within the preceding 18 months
being  at least  one and three-fourths  the Annual Interest  Requirements on all
Mortgage Bonds at  the time Outstanding,  Mortgage Bonds then  applied for,  all
outstanding  Pledged Bonds  other than  Pledged Bonds  held by  the New Mortgage
Trustee under  the  New  Mortgage,  and all  other  indebtedness  (with  certain
exceptions) secured by a lien prior to the lien of the New Mortgage, except that
no such net earnings requirement need be met if the additional Mortgage Bonds to
be  issued are to have no Stated Interest Rate prior to Maturity. The Company is
not required  to satisfy  the  net earnings  requirement  prior to  issuance  of
Mortgage  Bonds  as  provided in  (1)  above  if the  Pledged  Bonds  issued and
delivered to the New Mortgage Trustee as  the basis for such issuance have  been
authenticated and delivered under the related Class "A" Mortgage on the basis of
retired  Pledged Bonds  unless (a) the  Stated Maturity of  such retired Pledged
Bonds is  a date  more than  five  years after  the date  of the  Company  Order
requesting  the authentication and  delivery of such Mortgage  Bonds and (b) the
Stated Interest Rate, if any, on such retired Pledged Bonds immediately prior to
Maturity is less than the Stated Interest  Rate, if any, on such Mortgage  Bonds
to  be  in  effect upon  the  initial  authentication and  delivery  thereof. In
addition, the Company is  not required to satisfy  the net earnings  requirement
prior  to issuance  of Mortgage Bonds  as provided  in (3) above  unless (a) the
Stated Maturity of the Retired  Bonds is a date more  than five years after  the
date  of the  Company Order requesting  the authentication and  delivery of such
Mortgage Bonds and (b) the Stated Interest  Rate, if any, on such Retired  Bonds
immediately  prior to Maturity is less than the Stated Interest Rate, if any, on
such Mortgage Bonds to be in effect upon the initial authentication and delivery
of such Mortgage  Bonds. In general,  the interest requirement  with respect  to
variable interest rate indebtedness, if any, is determined with reference to the
rate  or rates in effect on the date immediately preceding such determination or
the rate to  be in  effect upon initial  authentication. (See  Section 1.03  and
Article Four).

    Adjusted  Net Earnings are calculated before, among other things, provisions
for income  taxes; depreciation  or amortization  of property;  interest on  any
indebtedness  and amortization of  debt discount and  expense; any non-recurring
charge to income of  whatever kind or nature  (including without limitation  the
recognition  of expense or impairment due to the non-recoverability of assets or
expense), whether or not recorded as a non-recurring item in the Company's books
of account; and any  refund of revenues previously  collected or accrued by  the
Company  subject to possible refund. With respect  to Mortgage Bonds of a series
subject to a  Periodic Offering (such  as a medium-term  note program), the  New
Mortgage Trustee will be entitled to receive a certificate evidencing compliance
with  the net earnings  requirements only once, at  or prior to  the time of the
first authentication and delivery of the  Mortgage Bonds of such series  (unless
the  Company Order requesting  the authentication and  delivery of such Mortgage
Bonds is delivered on or after the date which is two years after the most recent
Net Earnings Certificate  was delivered,  in which case  an updated  certificate
would be required to be delivered). (See Sections 1.03 and 4.01.)

    Property  Additions generally  include any  property which  is owned  by the
Company and is subject to the lien of the New Mortgage, except any property  the
cost  of  acquisition or  construction  of which  is  properly chargeable  to an
operating expense account of the Company. (See Section 1.04.)

    Unless otherwise  provided  in  the applicable  Prospectus  Supplement,  the
Company will issue the Mortgage Bonds on the basis of Pledged Bonds (I.E., First
Mortgage Bonds) issued under its First Mortgage.

                                       25

RELEASE OF PROPERTY

    The  Company may obtain the release from the lien of the New Mortgage of any
Mortgaged Property if the Fair Value of all of the Mortgaged Property (excluding
the Mortgaged Property to be released but including any Mortgaged Property to be
acquired by the Company with the  proceeds of, or otherwise in connection  with,
such  release) equals or exceeds an amount equal to twenty-fifteenths (20/15ths)
of the aggregate principal amount of Mortgage Bonds Outstanding and bonds issued
under Class "A" Mortgages outstanding (other than Pledged Bonds).

    The New Mortgage provides simplified procedures for the release of  property
which  has been released from the lien of a Class "A" Mortgage, minor properties
and property taken by eminent domain,  and provides for dispositions of  certain
obsolete  property and grants or surrender of certain rights without any release
or consent by the New Mortgage Trustee.

    If any property released from the lien  of the New Mortgage continues to  be
owned by the Company after such release, the New Mortgage will not become a lien
on  any  improvement,  extension  or  addition  to  such  property  or renewals,
replacements or substitutions of or for any part or parts of such property. (See
Article Eight.)

WITHDRAWAL OF CASH

    Subject to certain  limitations, cash  held by the  New Trustee  may (1)  be
withdrawn  by the Company (a) to the extent of the Cost or Fair Value (whichever
is less) of Unbonded Property Additions, after certain deductions and  additions
primarily including adjustments to offset retirements, or (b) in an amount equal
to  twenty-fifteenths (20/15ths) of  the aggregate principal  amount of Mortgage
Bonds that the Company would be entitled to issue on the basis of Retired  Bonds
(with  the  entitlement  to such  issuance  being  waived by  operation  of such
withdrawal), or (c) in  an amount equal to  twenty-fifteenths (20/15ths) of  the
aggregate  principal amount of  any Outstanding Mortgage  Bonds delivered to the
New Trustee, or  (2) upon  the request  of the Company,  be applied  to (a)  the
purchase of Mortgage Bonds (at prices not exceeding twenty-fifteenths (20/15ths)
of  the principal  amount thereof)  or (b) the  redemption or  payment at Stated
Maturity of Mortgage Bonds (with any Mortgage Bonds received by the New  Trustee
pursuant  to these  provisions being canceled  by the New  Trustee) (see Section
8.06); provided, however, that cash deposited  with the New Mortgage Trustee  as
the basis for the authentication and delivery of Mortgage Bonds, as well as cash
representing  a payment of principal of Pledged  Bonds, may only be withdrawn in
an amount equal to the aggregate principal amount of Mortgage Bonds the  Company
would  be entitled to issue on any  basis (with the entitlement to such issuance
being waived by operation of such withdrawal),  or may, upon the request of  the
Company,  be applied to the purchase, redemption or payment of Mortgage Bonds at
prices not  exceeding,  in the  aggregate,  the principal  amount  thereof  (See
Sections 4.05 and 7.02).

CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

    The  Company may not consolidate with or merge into any other corporation or
convey, transfer  or lease  the Mortgaged  Property as  or substantially  as  an
entirety  to any  person unless (a)  such transaction  is on such  terms as will
fully preserve the  lien and security  of the  New Mortgage and  the rights  and
powers  of the New Mortgage  Trustee and Holders, (b)  the corporation formed by
such consolidation  or into  which the  Company is  merged or  the person  which
acquires  by conveyance or transfer, or  which leases, the Mortgaged Property as
or substantially as an  entirety is a corporation  organized and existing  under
the  laws of the United  States of America or any  state or territory thereof or
the District of Columbia, and such corporation executes and delivers to the  New
Mortgage  Trustee a supplemental indenture, which contains an assumption by such
corporation of the due and punctual payment of the principal of and premium,  if
any,  and interest, if any, on the Mortgage  Bonds and the performance of all of
the covenants of the Company under the New Mortgage and which contains a  grant,
conveyance,  transfer and mortgage by the corporation confirming the lien of the
New Mortgage on the Mortgaged Property and subjecting to such lien all  property
thereafter  acquired by the  corporation which shall  constitute an improvement,
extension or addition  to the Mortgaged  Property or a  renewal, replacement  or
substitution  of  or  for  any  part  thereof,  and,  at  the  election  of  the
corporation, subjecting to the lien of the New Mortgage such other property then
owned or thereafter acquired by the

                                       26

corporation as the corporation shall  specify, and (c) in  the case of a  lease,
such  lease will be made expressly subject  to termination by the Company or the
New Mortgage Trustee at any time during the continuance of an Event of  Default.
(See Section 13.01.)

   
    Other  than the security afforded by the  lien of the First Mortgage and the
New Mortgage and the restrictions on  the issuance of additional First  Mortgage
Bonds  and New Mortgage Bonds, there are  no provisions of the First Mortgage or
the New Mortgage which afford the holders of the Offered Bonds protection in the
event of a highly  leveraged transaction, reorganization, restructuring,  merger
or similar transaction involving the Company. Neither the First Mortgage nor the
New  Mortgage contain provisions  requiring the repurchase  of the Offered Bonds
upon a change in control of the Company.
    

MODIFICATION OF NEW MORTGAGE
    Without the consent of any Holders, the Company and the New Mortgage Trustee
may enter into  one or  more supplemental indentures  for any  of the  following
purposes:

        (a)  to evidence the succession of another person to the Company and the
    assumption by any such successor of the covenants of the Company in the  New
    Mortgage and in the Mortgage Bonds; or

        (b)  to add one or more covenants of the Company or other provisions for
    the benefit of  all Holders  or for  the benefit of  the Holders  of, or  to
    remain  in effect only so long as there shall be Outstanding, Mortgage Bonds
    of one or  more specified series,  or one  or more tranches  thereof, or  to
    surrender any right or power conferred upon the Company by the New Mortgage;
    or

        (c)  to correct or amplify  the description of any  property at any time
    subject to the lien  of the New  Mortgage, or better  to assure, convey  and
    confirm  to the New Mortgage Trustee any  property subject or required to be
    subjected to the lien of the New Mortgage, or to subject to the lien of  the
    New Mortgage additional property; or

        (d)  to convey, transfer and  assign to the New  Mortgage Trustee and to
    subject to the lien of the New Mortgage with the same force and effect as if
    included in the New Mortgage, property  of subsidiaries of the Company  used
    or  to be used for one or more  purposes which if owned by the Company would
    constitute property  used or  to be  used for  one or  more of  the  Primary
    Purposes of the Company's Business, which property shall for all purposes of
    the New Mortgage be deemed to be property of the Company, together with such
    other  provisions as may be appropriate  to express the respective rights of
    the New Mortgage Trustee and the Company in regard thereto; or

        (e) to change or eliminate any provision  of the New Mortgage or to  add
    any  new  provision  to the  New  Mortgage,  provided that  if  such change,
    elimination or addition adversely  affects the interests  of the Holders  of
    the  Mortgage Bonds of any  series or tranche in  any material respect, such
    change, elimination or addition will  become effective with respect to  such
    series  or tranche  only when  no Mortgage  Bond of  such series  or tranche
    remains outstanding under the New Mortgage; or

        (f) to establish the form or terms  of the Mortgage Bonds of any  series
    or tranche as permitted by the New Mortgage; or

        (g)  to provide for the authentication and delivery of bearer securities
    and coupons appertaining thereto representing interest, if any, thereon  and
    for  the procedures for  the registration, exchange  and replacement thereof
    and for the giving of notice to, and the solicitation of the vote or consent
    of, the  holders thereof,  and  for any  and  all other  matters  incidental
    thereto; or

        (h)  to  evidence and  provide for  the acceptance  of appointment  by a
    successor trustee or by a co-trustee or separate trustee; or

        (i) to provide  for the  procedures required  to permit  the Company  to
    utilize, at its option, a noncertificated system of registration for all, or
    any series or tranche of, the Mortgage Bonds; or

        (j)  to change any place where (1) the principal of and premium, if any,
    and interest, if any, on  the Mortgage Bonds of  any series, or any  tranche
    thereof,  will be  payable, (2)  any Mortgage  Bonds of  any series,  or any
    tranche thereof, may be  surrendered for registration  of transfer, (3)  any
    Mortgage Bonds

                                       27

    of  any series, or any tranche thereof, may be surrendered for exchange, and
    (4) notices and demands to  or upon the Company  in respect of the  Mortgage
    Bonds  of any series,  or any tranche  thereof, and the  New Mortgage may be
    served; or

        (k) to  cure  any ambiguity,  to  correct or  supplement  any  provision
    therein  which may  be defective  or inconsistent  with any  other provision
    therein, or to make any  changes to the provisions  thereof or to add  other
    provisions  with  respect to  matters and  questions  arising under  the New
    Mortgage, so long as such other changes or additions do not adversely affect
    the interests of the Holders of Mortgage  Bonds of any series or tranche  in
    any material respect; or

        (l) to reflect changes in Generally Accepted Accounting Principles; or

        (m)  to provide the terms and  conditions of the exchange or conversion,
    at the  option of  the  holders of  Mortgage Bonds  of  any series,  of  the
    Mortgage  Bonds of such series for or into Mortgage Bonds of other series or
    stock or other securities of the Company or any other corporation; or

        (n) to change the  words "Mortgage Bonds" to  "First Mortgage Bonds"  in
    the  descriptive  title  of all  Outstanding  Bonds  at any  time  after the
    discharge of the First Mortgage; or

        (o) to comply with the rules  or regulations of any national  securities
    exchange on which any of the Mortgage Bonds may be listed; or

        (p) to modify Section 3.01(a) to increase the aggregate principal amount
    of  Mortgage Bonds  which may be  authenticated and delivered  under the New
    Mortgage. (See Section 14.01.)

    Without limiting the generality of the foregoing, if the Trust Indenture Act
is amended after  the date  of the  New Mortgage  in such  a way  as to  require
changes  to  the  New  Mortgage  or  the  incorporation  therein  of  additional
provisions or so  as to  permit changes to,  or the  elimination of,  provisions
which,  at the date of the New Mortgage or at any time thereafter, were required
by the Trust Indenture Act to be contained in the New Mortgage, the Company  and
the New Mortgage Trustee may, without the consent of any Holders, enter into one
or  more  supplemental indentures  to evidence  or  effect such  amendment. (See
Section 14.01.)

   
    Except as provided  above, the consent  of the  Holders of not  less than  a
majority  in aggregate principal amount of the Mortgage Bonds of all series then
Outstanding, considered as one class, is required for the purpose of adding  any
provisions  to, or changing in any manner,  or eliminating any of the provisions
of, the New Mortgage pursuant to one or more supplemental indentures;  provided,
however,  if  less than  all of  the  series of  Mortgage Bonds  Outstanding are
directly affected by a proposed supplemental indenture, then the consent only of
the Holders of a majority in aggregate principal amount of Outstanding  Mortgage
Bonds  of all  series so  directly affected,  considered as  one class,  will be
required; and provided, further, that if  the Mortgage Bonds of any series  have
been  issued in more than one tranche and if the proposed supplemental indenture
directly affects the rights of  the Holders of one or  more, but less than  all,
such  tranches, then the consent only of  the Holders of a majority in aggregate
principal amount of the Outstanding Mortgage  Bonds of all tranches so  directly
affected, considered as one class, will be required; and provided, further, that
no such amendment or modification may, without the consent of each Holder of the
Outstanding  New Mortgage of  each series or  tranche directly affected thereby,
(a) change  the Stated  Maturity of  the  principal of,  or any  installment  of
principal  of or interest on, any Mortgage  Bond, or reduce the principal amount
thereof or the rate  of interest thereon  (or the amount  of any installment  of
interest  thereon) or change the  method of calculating such  rate or reduce any
premium payable  upon  the redemption  thereof,  or  reduce the  amount  of  the
principal of a Discount Bond that would be due and payable upon a declaration of
acceleration  of maturity or change the coin  or currency (or other property) in
which any Mortgage Bond or  any premium or the  interest thereon is payable,  or
impair the right to institute suit for the enforcement of any such payment on or
after  the Stated Maturity thereof  (or, in the case  of redemption, on or after
the redemption date), (b) permit the creation  of any lien ranking prior to  the
lien  of  the New  Mortgage  with respect  to all  or  substantially all  of the
Mortgaged Property  or  terminate  the  lien  of the  New  Mortgage  on  all  or
substantially  all  of the  Mortgaged Property,  or deprive  such Holder  of the
benefit of  the  security of  the  lien of  the  New Mortgage,  (c)  reduce  the
percentage  in principal amount of the Outstanding Mortgage Bonds of such series
or tranche,  the consent  of  the Holders  of which  is  required for  any  such
supplemental
    

                                       28

   
indenture,  or the consent of the Holder of  which is required for any waiver of
compliance with any provision of the New Mortgage or any default thereunder  and
its consequences, or reduce the requirements for quorum or voting, or (d) modify
certain  of  the  provisions  of  the  New  Mortgage  relating  to  supplemental
indentures, waiver  of  certain  covenants  and  waivers  of  past  defaults.  A
supplemental  indenture  which  changes  or  eliminates  any  covenant  or other
provision of the New Mortgage which  has expressly been included solely for  the
benefit of the Holders of, or which is to remain in effect only so long as there
shall  be Outstanding Mortgage Bonds of one  or more specified series, or one or
more tranches thereof, or modifies the  rights of the Holders of Mortgage  Bonds
of  such series or  tranches with respect  to such covenant  or other provision,
will be deemed not to affect the rights under the New Mortgage of the Holders of
the Mortgage Bonds of any other series or tranche. (See Section 14.02.)
    

WAIVER

    The Holders of  at least  a majority in  aggregate principal  amount of  all
Mortgage  Bonds  may  waive the  Company's  obligations to  comply  with certain
covenants,  including  the  Company's  obligation  to  maintain  its   corporate
existence  and  properties,  pay  taxes and  discharge  liens,  maintain certain
insurance and to make  such recordings and filings  as are necessary to  protect
the security of the Holders and the rights of the New Mortgage Trustee, provided
that such waiver occurs before the time such compliance is required. The Holders
of at least a majority of the aggregate principal amount of Outstanding Mortgage
Bonds  of all affected series  or tranches, considered as  one class, may waive,
before the time for such compliance, compliance with the Company's obligation to
maintain an office or agency where the Mortgage Bonds of such series or tranches
may  be  surrendered  for  payment,  registration,  transfer  or  exchange,  and
compliance  with  any  other  covenant  specified  in  a  supplemental indenture
respecting such series or tranches. (See Section 6.09.)

EVENTS OF DEFAULT

    Each of the following events constitutes  an Event of Default under the  New
Mortgage:

        (1)  failure to pay interest  on any Mortgage Bond  within 60 days after
    the same becomes due;

        (2) failure to pay  principal or premium, if  any, on any Mortgage  Bond
    within 15 days after its Maturity;

        (3)  failure to  perform or  breach of any  covenant or  warranty of the
    Company in the New Mortgage (other than  a covenant or a warranty a  default
    in the performance of which or breach of which is dealt with elsewhere under
    this  paragraph) for a period  of 60 days after there  has been given to the
    Company by the New Mortgage Trustee, or to the Company and the New  Mortgage
    Trustee  by the Holders of  at least 50% in  principal amount of Outstanding
    Mortgage Bonds,  a written  notice  specifying such  default or  breach  and
    requiring  it to be  remedied and stating  that such notice  is a "Notice of
    Default," unless the New Mortgage Trustee,  or the New Mortgage Trustee  and
    the  Holders  of a  principal amount  of  Mortgage Bonds  not less  than the
    principal amount of Mortgage Bonds the Holders of which gave such notice, as
    the case may be, agree  in writing to an extension  of such period prior  to
    its expiration; provided, however, that the New Mortgage Trustee, or the New
    Mortgage  Trustee and such  Holders, as the  case may be,  will be deemed to
    have agreed to  an extension of  such period if  corrective action has  been
    initiated by the Company within such period and is being diligently pursued;

        (4) certain events relating to reorganization, bankruptcy and insolvency
    of the Company and appointment of a receiver or trustee for its property; or

        (5)  the occurrence of  a Matured Event  of Default under  any Class "A"
    Mortgage; provided that  the waiver  or cure of  any such  Matured Event  of
    Default  and the rescission and annulment  of the consequences thereof shall
    constitute a waiver  of the  corresponding Event  of Default  under the  New
    Mortgage  and a rescission  and annulment of  the consequences thereof. (See
    Section 10.01.)

REMEDIES

    If an  Event of  Default occurs  and is  continuing, then  the New  Mortgage
Trustee  or  the Holders  of not  less than  a majority  in principal  amount of
Mortgage Bonds then Outstanding may declare the principal

                                       29

amount (or  if  the Mortgage  Bonds  are Discount  Bonds,  such portion  of  the
principal  amount as  may be  provided for such  Discount Bonds  pursuant to the
terms of the New Mortgage) of all  of the Mortgage Bonds together with  premium,
if any, and interest accrued, if any, thereon to be immediately due and payable.
At  any time after such  declaration of the maturity  of the Mortgage Bonds then
Outstanding, but before the sale of any  of the Mortgaged Property and before  a
judgment  or decree  for payment of  money shall  have been obtained  by the New
Mortgage Trustee as provided in the New Mortgage, the Event or Events of Default
giving rise to such  declaration of acceleration will,  without further act,  be
deemed  to have  been waived,  and such  declaration and  its consequences will,
without further act, be deemed to have been rescinded and annulled, if:

        (a) the Company has  paid or deposited with  the New Mortgage Trustee  a
    sum sufficient to pay:

           (1)  all  overdue  interest,  if  any,  on  all  Mortgage  Bonds then
       Outstanding;

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

           (3)  all amounts due to the  New Mortgage Trustee as compensation and
       reimbursement as provided in the New Mortgage; and

        (b) any other Event or Events  of Default other than the non-payment  of
    the  principal of Mortgage Bonds which shall  have become due solely by such
    declaration of acceleration, shall have been cured or waived as provided  in
    the New Mortgage. (See Sections 10.02 and 10.17.)

    The  New  Mortgage provides  that, under  certain  circumstances and  to the
extent permitted by law, if  an Event of Default  occurs and is continuing,  the
New  Mortgage Trustee has the power to  take possession of, and to hold, operate
and manage, the Mortgaged Property, or with or without entry, sell the Mortgaged
Property. If the Mortgaged Property is sold, whether by the New Mortgage Trustee
or pursuant to judicial proceedings,  the principal of the Outstanding  Mortgage
Bonds,  if  not  previously  due, will  become  immediately  due,  together with
premium, if  any, and  any  accrued interest.  (See  Sections 10.03,  10.04  and
10.05.)

    If  an Event of Default occurs and  is continuing, the Holders of a majority
in principal amount of the Mortgage  Bonds then Outstanding will have the  right
to  direct the  time, method  and place  of conducting  any proceedings  for any
remedy available to the  New Mortgage Trustee or  exercising any trust or  power
conferred on the New Mortgage Trustee, provided that (a) such direction does not
conflict  with any rule of  law or with the New  Mortgage, and could not involve
the New Mortgage Trustee in personal liability in circumstances where  indemnity
would  not, in the New Mortgage Trustee's sole discretion, be adequate, (b) such
direction is not unduly prejudicial to  the rights of the nonassenting  Holders,
and  (c) the New Mortgage Trustee may take any other action deemed proper by the
New Mortgage  Trustee  which is  not  inconsistent with  such  discretion.  (See
Section 10.16.)

    The  New Mortgage provides that no Holder of any Mortgage Bond will have any
right to institute any  proceeding, judicial or otherwise,  with respect to  the
New  Mortgage, or for the appointment of a receiver or trustee, or for any other
remedy thereunder,  unless (a)  such  Holder has  previously  given to  the  New
Mortgage  Trustee  written notice  of  a continuing  Event  of Default;  (b) the
Holders of  not  less than  a  majority in  aggregate  principal amount  of  the
Mortgage  Bonds then Outstanding  have made written request  to the New Mortgage
Trustee to institute proceedings  in respect of such  Event of Default and  have
offered   the  New  Mortgage  Trustee  reasonable  indemnity  against  cost  and
liabilities incurred in complying with such  request; and (c) for 60 days  after
receipt  of such notice,  the New Mortgage  Trustee has failed  to institute any
such proceeding and no direction inconsistent  with such request has been  given
to  the  New Mortgage  Trustee during  such 60-day  period by  the Holders  of a
majority in  aggregate  principal amount  of  Mortgage Bonds  then  Outstanding.
Furthermore,  no Holder will be entitled to  institute any such action if and to
the extent  that such  action would  disturb or  prejudice the  rights of  other
Holders.  (See Section  10.11.) Notwithstanding  that the  right of  a Holder to
institute a proceeding with  respect to the New  Mortgage is subject to  certain
conditions  precedent, each Holder  of a Mortgage  Bond has the  right, which is
absolute and unconditional, to receive payment of the principal of and  premium,
if    any,   and    interest,   if   any,    on   such    Mortgage   Bond   when

                                       30

due and to  institute suit for  the enforcement  of any such  payment, and  such
rights  may not  be impaired  without the consent  of such  Holder. (See Section
10.12.) The New Mortgage provides that the New Mortgage Trustee give the Holders
notice of any default under the New Mortgage to the extent required by the Trust
Indenture Act, unless such default shall have been cured or waived, except  that
no  such notice to Holders of a  default of the character described in paragraph
(3) under "Events of Default"  shall be given until at  least 45 days after  the
occurrence  thereof.  (See Section  11.02.)  The Trust  Indenture  Act currently
permits the  New Mortgage  Trustee to  withhold notice  of default  (except  for
certain  payment defaults) if the New  Mortgage Trustee in good faith determines
the withholding of such notice to be in the interests of the Holders.

    As a condition precedent to certain  actions by the New Mortgage Trustee  in
the enforcement of the lien of the New Mortgage and institution of action on the
Mortgage  Bonds, the New Mortgage Trustee may require adequate indemnity against
costs, expense  and liabilities  to be  incurred in  connection therewith.  (See
Sections 10.11 and 11.01.)

    In  addition to every other  right and remedy provided  in the New Mortgage,
the New Mortgage Trustee may exercise any  right or remedy available to the  New
Mortgage  Trustee in  its capacity  as owner and  holder of  Pledged Bonds which
arises as a result of a default or Matured Event of Default under any Class  "A"
Mortgage,  whether or not  an Event of  Default under the  New Mortgage has then
occurred and is continuing. (See Section 10.20.)

DEFEASANCE

    Any Mortgage Bond or Bonds, or any portion of the principal amount  thereof,
will  be deemed  to have  been paid for  purposes of  the New  Mortgage, and the
entire indebtedness of  the Company in  respect thereof will  be deemed to  have
been  satisfied and discharged, if there has been irrevocably deposited with the
New Mortgage Trustee, in trust: (a) money (including Funded Cash) in the  amount
which  will be  sufficient, or  (b) Eligible  Obligations (as  described below),
which do not contain  provisions permitting the  redemption or other  prepayment
thereof  at the option of the issuer  thereof, the principal of and the interest
on which when  due, without  any regard  to reinvestment  thereof, will  provide
monies  which will be sufficient, or (c) a combination of (a) and (b) which will
be sufficient,  to pay  when  due the  principal of  and  premium, if  any,  and
interest,  if any,  due and  to become  due on  such Mortgage  Bond or  Bonds or
portions thereof. (See  Section 9.01.)  For this  purpose, Eligible  Obligations
include direct obligations of, or obligations unconditionally guaranteed by, the
United  States of America, entitled to the  benefit of the full faith and credit
thereof, and  certificates,  depositary  receipts  or  other  instruments  which
evidence  a direct  ownership interest  in such  obligations or  in any specific
interest or principal payments due in respect thereof.

    While there is no  legal precedent directly on  point, it is possible  that,
for  federal  income tax  purposes, any  deposit  contemplated in  the preceding
paragraph could be treated as a  taxable exchange of the related Mortgage  Bonds
for  an issue of obligations of  the trust or a direct  interest in the cash and
securities held in the trust. In that case, Holders of such Mortgage Bonds would
recognize gain or loss  as if the  trust obligations or  the cash or  securities
deposited,  as the case may  be, had actually been  received by them in exchange
for their Mortgage Bonds. Such Holders  thereafter would be required to  include
in  income a  share of  the income,  gain or  loss of  the trust.  The amount so
required to be included in income could be different from the amount that  would
be includible in the absence of such deposit. Prospective investors are urged to
consult  their own tax advisors as to  the specific consequences to them of such
deposit.

RESIGNATION OF THE NEW MORTGAGE TRUSTEE

    The New Mortgage  Trustee may resign  at any time  by giving written  notice
thereof  to the Company or may be removed at any time by Act of the Holders of a
majority in principal amount of Mortgage Bonds then Outstanding delivered to the
New Mortgage  Trustee and  the Company.  No resignation  or removal  of the  New
Mortgage Trustee and no appointment of a successor trustee will become effective
until  the acceptance of  appointment by a successor  trustee in accordance with
the requirements  of the  New Mortgage.  In addition,  so long  as no  Event  of
Default  or event which, after notice or lapse of time, or both, would become an
Event of Default has occurred and is continuing, under certain circumstances, if
the Company has delivered to the New Mortgage Trustee a resolution of its  Board
of Directors appointing a successor trustee

                                       31

and such successor has accepted such appointment in accordance with the terms of
the  New Mortgage, the New Mortgage Trustee  will be deemed to have resigned and
the successor will  be deemed to  have been appointed  as trustee in  accordance
with the New Mortgage. (See Section 11.10.)

CONCERNING THE NEW MORTGAGE TRUSTEE

    The  Chase Manhattan  Bank (N.A.), the  Trustee under the  New Mortgage, has
been a regular depositary of funds of the Company. As trustee under both the New
Mortgage and the First  Mortgage, The Chase Manhattan  Bank (N.A.) would have  a
conflicting  interest for  purposes of  the Trust Indenture  Act if  an Event of
Default were to  occur under  either mortgage. In  that case,  the New  Mortgage
Trustee  may be  required to  eliminate such  conflicting interest  by resigning
either as New  Mortgage Trustee or  as First Mortgage  Trustee. There are  other
instances  under the Trust Indenture Act  which would require the resignation of
the New  Mortgage Trustee,  such as  an affiliate  of the  New Mortgage  Trustee
acting as underwriter with respect to any of the Mortgage Bonds.

TRANSFER

    The transfer of the Mortgage Bonds may be registered, and Mortgage Bonds may
be  exchanged  for other  Mortgage  Bonds of  the  same series  and  tranche, of
authorized denominations and of  like tenor and  aggregate principal amount,  at
the  office  of The  Chase  Manhattan Bank  (N.A.),  as Bond  Registrar  for the
Mortgage Bonds, in  Brooklyn, New  York. The Company  may change  the place  for
registration  of  transfer  of  the  Mortgage Bonds,  may  appoint  one  or more
additional Bond  Registrars (including  the  Company) and  may remove  any  Bond
Registrar,  all at its discretion. (See Section 6.02.) The applicable Prospectus
Supplement will  identify  any  new  place  for  registration  of  transfer  and
additional  Bond Registrar appointed, and will  disclose the removal of any Bond
Registrar effected, prior to the date  of such Prospectus Supplement. Except  as
otherwise  provided in the  applicable Prospectus Supplement,  no service charge
will be made for any transfer or exchange of the Mortgage Bonds, but the Company
may require payment of a sum sufficient  to cover any tax or other  governmental
charge  that may be imposed  in connection with any  registration of transfer or
exchange of the Mortgage Bonds. The Company  will not be required to issue,  and
no  Bond Registrar will be required to  register, the transfer of or to exchange
(a) Mortgage Bonds of any series (including the Mortgage Bonds) during a  period
of  15 days prior to  giving any notice of redemption,  or (b) any Mortgage Bond
selected for redemption in  whole or in part,  except the unredeemed portion  of
any Mortgage Bond being redeemed in part. (See Section 3.05.)

                DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

    The following description sets forth certain general terms and provisions of
the  Subordinated Debt Securities to which any Prospectus Supplement may relate.
The particular  terms  of  the  Subordinated  Debt  Securities  offered  by  any
Prospectus  Supplement and the extent,  if any, to which  such general terms and
provisions may apply  to the  Subordinated Debt  Securities so  offered will  be
described in the Prospectus Supplement relating to such Debt Securities.

   
    The  Subordinated Debt Securities may be issued, in one or more series, from
time to time  under an  Indenture dated  as of                      , 1995  (the
"Indenture"),  between the Company and The Chase Manhattan Bank N.A., as trustee
(the "Indenture Trustee"), which shall act as indenture trustee for the purposes
of the Trust Indenture  Act of 1939,  as amended. The form  of the Indenture  is
filed  as an  exhibit to the  Registration Statement. Capitalized  terms used in
this section which are not otherwise  defined in this Prospectus shall have  the
meanings set forth in the Indenture.
    

    The  following  summaries of  certain  provisions of  the  Subordinated Debt
Securities and the Indenture do not purport  to be complete and are subject  to,
and  are qualified in their entirety by  express reference to all the provisions
of the Indenture, including the definitions therein of certain terms.

GENERAL

    The Subordinated  Debt Securities  will be  direct, unsecured,  subordinated
obligations of the Company.

    The  Indenture does not limit the aggregate principal amount of Subordinated
Debt Securities that  may be  issued thereunder and  provides that  Subordinated
Debt Securities may be issued thereunder from time to

                                       32

time in one or more series. The Subordinated Debt Securities are issuable in one
or  more  series pursuant  to  an indenture  supplement  to the  Indenture  or a
resolution of the Company's  Board of Directors or  a special committee  thereof
(each, a "Supplemental Indenture").

    The  Restated Certificate of Incorporation of the Company limits, subject to
certain exceptions, the amount  of unsecured indebtedness  that the Company  may
issue  or assume, without the consent of the  holders of a majority of the total
number of shares of preferred stock then outstanding, to 25% of the aggregate of
(i) the total  principal amount  of all  outstanding bonds  or other  securities
representing  secured indebtedness  of the  Company, and  (ii) the  total of the
capital stocks  and premiums  thereon and  the surplus  of the  Company as  then
stated  on the Company's books. At March 31, 1995, the Company could have issued
approximately $57 million  of unsecured indebtedness  (such as the  Subordinated
Debt Securities) without violating this provision.

   
    Reference  is made to the Prospectus Supplement relating to any Subordinated
Debt Securities  being offered  for,  among other  things, the  following  terms
thereof: (1) the title of the Subordinated Debt Securities; (2) any limit on the
aggregate  principal  amount  of  such  Subordinated  Debt  Securities;  (3) the
percentage of the principal  amount at which  such Subordinated Debt  Securities
will  be issued and, if other than  the principal amount thereof, the portion of
the principal amount thereof payable upon acceleration of the maturity  thereof,
or  the method by which such portion shall  be determined; (4) the date or dates
on which the principal of such Subordinated Debt Securities will be payable; (5)
the rights,  if any,  to defer  payments of  interest on  the Subordinated  Debt
Securities  by extending the  interest payment period, and  the duration of such
extensions; (6) the subordination terms  of the Subordinated Debt Securities  of
such  series; (7) the rate  or rates at which  such Subordinated Debt Securities
will bear  interest,  or  the method  by  which  such rate  or  rates  shall  be
determined,  and the date or dates from which such interest shall accrue, or the
method by which such date or dates  shall be determined; (8) the dates on  which
such  interest will  be payable  and the Regular  Record Dates  for any Interest
Payment Dates  and the  basis on  which interest  shall be  calculated; (9)  the
dates,  if any,  on which, the  price or  prices at which  the Subordinated Debt
Securities may, pursuant to any  mandatory or optional sinking fund  provisions,
be  redeemed by  the Company  and other  detailed terms  and provisions  of such
sinking funds; (10) the date,  if any, after which, and  the price or prices  at
which, the Subordinated Debt Securities may, pursuant to any optional redemption
provisions,  be redeemed at the option of  the Company or of the Holder thereof,
and other  detailed  terms and  provisions  of such  optional  redemption;  (11)
whether  and under what circumstances the Company will pay Additional Amounts as
contemplated by  Section  1005  of  the  Indenture  on  such  Subordinated  Debt
Securities  to  any Holder  who is  not  a United  States person  (including any
modification to the definition of such term as provided for in the Indenture  as
originally  executed) in respect  to any tax,  assessment or governmental charge
and, if so, whether the Company will have the option to redeem such Subordinated
Debt Securities rather than  pay such Additional Amounts  (and the terms of  any
such  option); (12)  any deletions  from, modifications  of or  additions to the
Events of Default or covenants of the Company with respect to such  Subordinated
Debt  Securities,  whether  or  not  such Events  of  Default  or  covenants are
consistent with the Events  of Default or covenants  set forth herein; (13)  any
security for such Subordinated Debt Securities; and (14) any other terms of such
Subordinated  Debt Securities. For a  description of the terms  of any series of
the Subordinated Debt Securities, reference must be made to both the  Prospectus
Supplement  relating  thereto  and  to  the  description  of  Subordinated  Debt
Securities set forth herein.
    

    Unless otherwise indicated  in the Prospectus  Supplement relating  thereto,
the  Subordinated Debt  Securities will  be issued  in United  States dollars in
fully registered form, without coupons, in denominations of $25 or any  integral
multiple thereof. No service charge will be made for any transfer or exchange of
the  Subordinated Debt Securities, but the Company  may require payment of a sum
sufficient to cover any tax or  other governmental charge payable in  connection
therewith.

    Unless  otherwise indicated  in the Prospectus  Supplement relating thereto,
the principal  of,  and  any  premium or  interest  on,  the  Subordinated  Debt
Securities  will  be  payable,  and the  Subordinated  Debt  Securities  will be
exchangeable and transfers thereof will be registrable, at the Place of Payment;
provided that, at the option of the Company, payment of interest may be made  by
check  mailed to the address of the person entitled thereto as it appears in the
Security Register.

                                       33

    The Indenture does not contain any provisions that may afford the Holders of
Subordinated  Debt  Securities protection  in the  event  of a  highly leveraged
transaction or  other  transaction  involving  the Company  that  may  occur  in
connection  with a takeover attempt resulting in  a decline in the credit rating
of the Subordinated  Debt Securities. The  Indenture also does  not contain  any
provisions that would limit the ability of the Company to incur indebtedness.

REGISTRATION AND TRANSFER

    Subordinated  Debt Securities  will be  issued as  Registered Securities and
either will be in certificated form or will be represented by Global Securities.
Registered Securities  will be  issuable in  denominations of  $25 and  integral
multiples  of $25 or in such  other denominations as may be  in the terms of the
Subordinated Debt Securities.

    Registered Securities will be  exchangeable for other Registered  Securities
of  the  same series  and  of a  like aggregate  principal  amount and  tenor of
different authorized denominations. Registered  Securities may be presented  for
registration  of transfer (duly endorsed or  accompanied by a written instrument
of transfer), at  the corporate  trust office of  the Indenture  Trustee in  New
York, New York, or at the office of any transfer agent designated by the Company
for  such purpose with respect to any series of Subordinated Debt Securities and
referred to in any Prospectus Supplement. No service charge will be made for any
transfer or  exchange  of Subordinated  Debt  Securities, but  the  Company  may
require  payment of  a sum  sufficient to  cover any  tax or  other governmental
charge payable in connection therewith.  If any Prospectus Supplement refers  to
any  transfer agent (in addition to  the Indenture Trustee) initially designated
by the Company with respect to  any series of Subordinated Debt Securities,  the
Company  may at any time  rescind the designation of  any such transfer agent or
approve a change in the location at  which any such transfer agent acts,  except
that,  if  Subordinated  Debt Securities  of  a  series are  issuable  solely as
Registered Securities, the Company will be required to maintain a transfer agent
in each Place of Payment for such series. The Company may at any time  designate
additional  transfer  agents with  respect to  any  series of  Subordinated Debt
Securities.

    In the event  of any  redemption of  any Subordinated  Debt Securities,  the
Company  shall  not be  required  to: (i)  issue,  register the  transfer  of or
exchange any  Subordinated Debt  Securities  during a  period beginning  at  the
opening of business 15 days before any selection of Subordinated Debt Securities
of  that series to be redeemed and ending at the close of business on the day of
mailing of the relevant notice of  redemption; (ii) register the transfer of  or
exchange  any  Subordinated  Debt  Securities, or  portion  thereof,  called for
redemption, except  the unredeemed  portion of  any Subordinated  Debt  Security
being redeemed in part; or (iii) issue, register the transfer of or exchange any
Subordinated  Debt Securities  that has  been surrendered  for repayment  at the
option of the Holder, except the portion if any, thereof not to be so repaid.

GLOBAL SECURITIES

    The Subordinated Debt Securities of  a series may be  issued in whole or  in
part  in the  form of  one or more  Global Securities  (as such  term is defined
below), which  will  be deposited  with,  or on  behalf  of, a  depositary  (the
"Depositary") or its nominee identified in the applicable Prospectus Supplement.
In  such case, one or more Global Securities will be issued in a denomination or
aggregate denomination equal to the portion of the aggregate principal amount of
outstanding Subordinated Debt Securities of the series to be represented by such
Global Security or Global Securities. Unless and until it is exchanged in  whole
or  in  part  for Subordinated  Debt  Securities  in registered  form,  a Global
Security may not be registered for transfer or exchange except as (i) a whole by
the Depositary for such Global  Security to a nominee  of such Depositary, by  a
nominee  of  such  Depositary to  such  Depositary  or another  nominee  of such
Depositary or by such Depositary, or by any nominee to a successor Depositary or
a nominee of such successor Depositary, and (ii) in the circumstances  described
in  the applicable Prospectus Supplement. The  term "Global Security," when used
with respect  to  any series  of  Subordinated  Debt Securities,  means  a  Debt
Security  that is executed by the Company and authenticated and delivered by the
Indenture Trustee to the Depositary or pursuant to the Depositary's instruction,
which shall be registered in the name of the Depositary or its nominee and which
shall represent, and shall  be denominated in an  amount equal to the  aggregate
principal amount of, all

                                       34

of  the Outstanding Subordinated  Debt Securities of such  series or any portion
thereof, in either case  having the same  terms, including, without  limitation,
the  same original  issue date,  date or  dates on  which principal  is due, and
interest rate or method of determining the interest rate.

    The specific terms of the depositary arrangement with respect to any portion
of a  series of  Subordinated Debt  Securities  to be  represented by  a  Global
Security  will be described in the applicable Prospectus Supplement. The Company
expects that the following provisions will apply to depositary arrangements.

    Unless  otherwise  specified  in   the  applicable  Prospectus   Supplement,
Subordinated  Debt Securities that are to be represented by a Global Security to
be deposited with or on behalf of  a Depositary will be represented by a  Global
Security  registered in  the name  of such Depositary  or its  nominee. Upon the
issuance of such Global Security, and  the deposit of such Global Security  with
or  on behalf of  the Depositary for  such Global Security,  the Depositary will
credit on  its  book-entry  registration  and  transfer  system  the  respective
principal amounts of the Subordinated Debt Securities represented by such Global
Security to the accounts of institutions that have accounts with such Depositary
or  its nominee ("participants"). The accounts to be credited will be designated
by the underwriters or agents of  such Subordinated Debt Securities or, if  such
Subordinated  Debt Securities are  offered and sold directly  by the Company, by
the Company. Ownership of beneficial interests  in such Global Security will  be
limited to participants or persons that may hold interests through participants.
Ownership  of beneficial interests by participants  in such Global Security will
be shown on, and the transfer of  that ownership interest will be effected  only
through,  records maintained  by the Depositary  or its nominee  for such Global
Security. Ownership of beneficial interests  in such Global Security by  persons
that  hold  through participants  will be  shown  on, and  the transfer  of that
ownership interest  within  such  participant will  be  effected  only  through,
records  maintained by such participant. The  laws of some jurisdictions require
that certain purchasers of securities take physical delivery of such  securities
in  certificated form.  The foregoing limitations  and such laws  may impair the
ability to transfer beneficial interests in such Global Securities.

    So long as  the Depositary for  a Global  Security, or its  nominee, is  the
registered  owner of such  Global Security, such Depositary  or such nominee, as
the case may be, will be considered the sole owner or Holder of the Subordinated
Debt Securities represented by such Global  Security for all purposes under  the
Indenture.  Unless otherwise specified in  the applicable Prospectus Supplement,
owners of beneficial interests in such  Global Security will not be entitled  to
have  Subordinated  Debt Securities  of the  series  represented by  such Global
Security registered in their names, will  not receive or be entitled to  receive
physical delivery of Subordinated Debt Securities of such series in certificated
form  and will not be considered the  Holders thereof for any purposes under the
Indenture. Accordingly, each person owning a beneficial interest in such  Global
Security  must rely on the  procedures of the Depositary  and, if such person is
not a  participant, on  the procedures  of the  participant through  which  such
person owns its interest to exercise any rights of a Holder under the Indenture.
The  Company understands that under existing  industry practices, if the Company
requests any action  of Holders or  an owner  of a beneficial  interest in  such
Global  Security  desires to  give any  notice or  take any  action a  Holder is
entitled to  give  or  take  under the  Indenture,  then  the  Depositary  would
authorize  the  participants  to  give  such notice  or  take  such  action, and
participants would authorize beneficial owners owning through such  participants
to  give  such  notice or  take  such action  or  would otherwise  act  upon the
instructions of beneficial owners owning through them.

    Principal of  and any  premium and  interest on  a Global  Security will  be
payable in the manner described in the applicable Prospectus Supplement.

CONSOLIDATION, MERGER AND SALE

    The  Indenture does not  contain any covenant  which restricts the Company's
ability to merge  or consolidate  with or into  any other  corporation, sell  or
convey all or substantially all of its assets to any person, firm or corporation
or otherwise engage in restructuring transactions.

EVENTS OF DEFAULT

    The  Indenture provides,  with respect  to any  series of  Subordinated Debt
Securities outstanding thereunder, that any one or more of the following  events
that has occurred and is continuing shall constitute an

                                       35

Event  of  Default: (i)  default  in the  payment of  any  interest upon  or any
Additional Amounts payable in respect of any Subordinated Debt Security of  that
series,  or of any  coupon appertaining thereto,  when the same  becomes due and
payable and continues for 30 days; provided, however, that, a valid extension of
the interest payment period by the Company for the Subordinated Debt  Securities
shall  not constitute a default in the payment of interest for this purpose, and
provided further that,  if Subordinated  Debt Securities  are issued  to a  NWPS
Trust,  or a  trustee of such  trust, in  connection with the  issuance of Trust
Securities by such NWPS Trust, said 30-day period will be replaced by a  ten-day
period;  (ii) default in the  payment of the principal of  or any premium on any
Subordinated Debt Security of  that series when due,  whether at maturity,  upon
redemption,  by  declaration  or  otherwise; provided,  however,  that,  a valid
extension of  the  maturity  of  the  Subordinated  Debt  Securities  shall  not
constitute  a default  for this  purpose; (iii)  default in  the deposit  of any
sinking fund payment,  when and as  due by  the terms of  any Subordinated  Debt
Securities  of that  series; (iv)  default in the  performance or  breach of any
covenant or  agreement of  the Company  in  the Indenture  with respect  to  any
Subordinated  Debt Security of that series,  continued for 60 days after written
notice to the Company from the Indenture Trustee or from the holders of at least
25% of the outstanding Subordinated Debt Securities of that series; (v)  certain
events  in bankruptcy,  insolvency or  reorganization of  the Company;  (vi) the
voluntary or involuntary dissolution, winding-up or termination of a NWPS  Trust
to  which (or to a trustee of  such trust to which) Subordinated Debt Securities
were issued in  connection with the  issuance of Trust  Securities by such  NWPS
Trust,   except  in  connection  with  the  distribution  of  Subordinated  Debt
Securities to the holders of Trust Securities in liquidation of such NWPS Trust,
the redemption of all  of the Trust  Securities of such  NWPS Trust, or  certain
mergers,  consolidations or amalgamations, each  as permitted by the Declaration
of such NWPS Trust; and (vii) any  other Event of Default provided with  respect
to  Subordinated Debt Securities of that series. The Company is required to file
annually with the Indenture Trustee an officer's certificate as to the Company's
compliance with all conditions and covenants under the Indenture. The  Indenture
provides  that  the Indenture  Trustee  may withhold  notice  to the  Holders of
Subordinated Debt Securities of any default, except in the case of a default  on
the  payment  of the  principal  of (or  premium), if  any,  or interest  on any
Subordinated Debt Securities or the payment of any sinking fund installment with
respect to such Subordinated Debt Securities if it considers it in the  interest
of the Holders of Subordinated Debt Securities to do so.

    If  an  Event  of  Default,  other  than  certain  events  with  respect  to
bankruptcy, insolvency  and reorganization  of the  Company or  any  Significant
Subsidiary,   occurs  and  is  continuing  with  respect  to  Subordinated  Debt
Securities of a particular series, the  Indenture Trustee or the Holders of  not
less than 25% in principal amount of Outstanding Subordinated Debt Securities of
that  series may  declare the Outstanding  Subordinated Debt  Securities of that
series due  and payable  immediately. If  an Event  of Default  with respect  to
certain events of bankruptcy, insolvency or reorganization of the Company or any
Significant  Subsidiary  with  respect  to  Subordinated  Debt  Securities  of a
particular series shall occur and be  continuing, then the principal of all  the
Outstanding  Subordinated Debt Securities of that series, and accrued and unpaid
interest thereon, shall automatically be due and payable without any act on  the
part of the Indenture Trustee or any Holder.

    Subject  to the provisions relating to  the duties of the Indenture Trustee,
if an  Event  of Default  with  respect to  Subordinated  Debt Securities  of  a
particular series occurs and is continuing, the Indenture Trustee shall be under
no obligation to exercise any of its rights or powers under the Indenture at the
request  or direction of any  of the Holders of  Subordinated Debt Securities of
such series, unless  such Holders shall  have offered to  the Indenture  Trustee
reasonable  indemnity and security  against the costs,  expenses and liabilities
that might be incurred by  it in compliance with  such request. Subject to  such
provisions  for the indemnification  of the Indenture Trustee,  the Holders of a
majority in principal amount of the Outstanding Subordinated Debt Securities  of
such  series  shall have  the  right to  direct the  time,  method and  place of
conducting any  proceeding for  any remedy  available to  the Indenture  Trustee
under the Indenture, or exercising any trust or power conferred on the Indenture
Trustee  with respect  to the Subordinated  Debt Securities of  that series. The
Indenture Trustee may refuse  to follow directions in  conflict with law or  the
Indenture that may involve the Indenture Trustee in personal liability or may be
unduly prejudicial to Holders not joining therein.

                                       36

    The  Holders  of  not  less  than a  majority  in  principal  amount  of the
Outstanding Subordinated Debt  Securities of any  series may, on  behalf of  the
Holders  of all the Subordinated Debt Securities  of such series and any related
coupons, waive any past default under the Indenture with respect to such  series
and  its consequences, except a  default (i) in the  payment of the principal of
(or premium, if any) or interest on or Additional Amounts payable in respect  of
any Subordinated Debt Security of such series unless such default has been cured
and  a sum sufficient to pay all  matured installments of interest and principal
due otherwise than by acceleration and any applicable premium has been deposited
with the Indenture Trustee or  (ii) in respect of  a covenant or provision  that
cannot  be  modified  or amended  without  the  consent of  the  Holder  of each
Outstanding Subordinated Debt Security of such series affected thereby.

MODIFICATION OR WAIVER

   
    Modification and amendment of the Indenture  may be made by the Company  and
the  Indenture  Trustee with  the  consent of  the Holders  of  not less  than a
majority in principal amount of all Outstanding Subordinated Debt Securities  or
any  series that are affected by  such modification or amendment; provided that,
no such modification or amendment may, without the consent of the Holder of each
Outstanding Subordinated Debt Security of  such series, among other things,  (i)
change  the Stated Maturity of the principal of  (or premium, if any, on) or any
installment of principal  of or interest  on any Subordinated  Debt Security  of
such  series, (ii) reduce the principal amount or the rate of interest on or any
Additional Amounts  payable in  respect  of, or  any  premium payable  upon  the
redemption  of, any  Subordinated Debt  Security of  such series,  or change the
redemption provisions  of  any Subordinated  Debt  Securities (iii)  change  any
obligation  of  the  Company  to  pay  Additional  Amounts  in  respect  of  any
Subordinated Debt Security of such series,  (iv) reduce the amount of  principal
of  a  Subordinated Debt  Security  of such  series  that is  an  Original Issue
Discount  Security  and  would  be  due  and  payable  upon  a  declaration   of
acceleration  of  the  Maturity  thereof,  (v)  adversely  affect  any  right of
repayment at the option of the Holder of any Subordinated Debt Security of  such
series,  (vi) change the  place or currency  of payment of  principal of, or any
premium or interest  on, any Subordinated  Debt Security of  such series,  (vii)
impair the right to institute suit for the enforcement of any such payment on or
after  the  Stated Maturity  thereof or  any Redemption  Date or  Repayment Date
therefor, (viii) reduce  the above-stated percentage  of Holders of  Outstanding
Subordinated  Debt Securities  of such series  necessary to modify  or amend the
Indenture or to consent to any waiver thereunder or reduce the requirements  for
voting  or quorum described below, (ix) modify the change of control provisions,
if any, or  (x) modify the  foregoing requirements or  reduce the percentage  of
Outstanding  Subordinated Debt Securities of such  series necessary to waive any
past default.
    

   
    Modification and amendment of the Indenture  may be made by the Company  and
the  Indenture  Trustee  without the  consent  of  any Holder,  for  any  of the
following purposes: (i)  to evidence  the succession  of another  person to  the
Company  as obligor  under the Indenture;  (ii) to  add to the  covenants of the
Company for the benefit of the Holders of all or any series of Subordinated Debt
Securities; (iii) to add Events of Default for the benefit of the Holders of all
or any series of Subordinated Debt  Securities; (iv) to change or eliminate  any
provisions  of the Indenture, provided that any such change or elimination shall
become effective only when there are no Outstanding Subordinated Debt Securities
of any series created  prior thereto that  are entitled to  the benefit of  such
provision; (v) to establish the form or terms of Subordinated Debt Securities of
any  series; (vi) to  secure the Subordinated Debt  Securities; (vii) to provide
for the acceptance of appointment by a successor Indenture Trustee or facilitate
the administration of the trusts under the Indenture by more than one  Indenture
Trustee;  and (viii) to  close the Indenture with  respect to the authentication
and delivery of additional  series of Subordinated Debt  Securities, or to  cure
any  ambiguity, defect or  inconsistency in the  Indenture, provided such action
does  not  adversely  affect  the  interest  of  Holders  of  Subordinated  Debt
Securities of any series.
    

CERTAIN COVENANTS

    If  Subordinated Debt Securities are issued to  a NWPS Trust or a trustee of
such trust in  connection with  the issuance of  Trust Securities  by such  NWPS
Trust and (i) there shall have occurred any event that would constitute an Event
of  Default or (ii) the Company shall be  in default with respect to its payment
of any obligations under the  related Guarantee or Common Securities  Guarantee,
then  (a)  the  Company  shall  not  declare or  pay  dividends  on,  or  make a
distribution with  respect  to  or  redeem,  purchase  or  acquire,  or  make  a

                                       37

liquidation  payment with  respect to,  any of  its capital  stock, and  (b) the
Company shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or  redeem any debt securities  issued by the Company  that
rank  pari passu with or junior  to such Subordinated Debt Securities; provided,
however, that, restriction (a) above does not apply to any stock dividends  paid
by  the Company where the dividend stock is  the same stock as that on which the
dividend is being paid.

    If Subordinated Debt Securities are issued to  a NWPS Trust or a trustee  of
such  trust in  connection with  the issuance of  Trust Securities  by such NWPS
Trust, and the Company shall have given notice of its election to defer payments
of interest  on such  Subordinated  Debt Securities  by extending  the  interest
payment  period as provided in  the Indenture and such  period, or any extension
thereof, shall  be continuing  then (a)  the Company  shall not  declare or  pay
dividends  on, or  make a  distribution with respect  to or  redeem, purchase or
acquire, or  make a  liquidation payment  with respect  to, any  of its  capital
stock,  and (b) the Company shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
the Company  that rank  pari passu  with  or junior  to such  Subordinated  Debt
Securities; provided, however, that, the restriction (a) above does not apply to
any stock dividends paid by the Company, where the dividend stock is the same as
that on which the dividend is being paid.

    If  Subordinated Debt Securities are issued to  a NWPS Trust or a trustee of
such trust in  connection with  the issuance of  Trust Securities  by such  NWPS
Trust, for so long as such Trust Securities remain outstanding, the Company will
covenant  (i) to  directly or indirectly  maintain 100% ownership  of the Common
Securities of such NWPS Trust;  provided, however, that any permitted  successor
of  the Company under  the Indenture may  succeed to the  Company's ownership of
such Common Securities and (ii) to use its reasonable efforts to cause such NWPS
Trust (a) to remain  a statutory business trust,  except in connection with  the
distribution  of Subordinated Debt Securities to the holders of Trust Securities
in liquidation of such NWPS Trust, the redemption of all of the Trust Securities
of such NWPS Trust, or certain mergers, consolidations or amalgamations, each as
permitted by the Declaration of such  NWPS Trust, and (b) to otherwise  continue
to  be  classified as  a  grantor trust  for  United States  federal  income tax
purposes.

SECURITY AND SUBORDINATION

    Any security for the Subordinated Debt  Securities will be described in  the
Prospectus Supplement that will accompany this Prospectus. The Subordinated Debt
Securities  will be subordinated and junior in right of payment to certain other
indebtedness of the Company to the extent set forth in the Prospectus Supplement
that will accompany this Prospectus.

GOVERNING LAW

    The Indenture and the Subordinated Debt Securities will be governed by,  and
construed in accordance with, the internal laws of the State of New York.

INFORMATION CONCERNING THE INDENTURE TRUSTEE

    The  Indenture Trustee,  prior to default,  undertakes to  perform only such
duties as are specifically set forth in the Indenture and, after default,  shall
exercise  the same degree of care as  a prudent individual would exercise in the
conduct of his  or her  own affairs. Subject  to such  provision, the  Indenture
Trustee is under no obligation to exercise any of the powers vested in it by the
Indenture  at the request of any  holder of Subordinated Debt Securities, unless
offered reasonable  indemnity by  such holder  against the  costs, expenses  and
liabilities  that  might  be  incurred thereby.  The  Indenture  Trustee  is not
required to expand or risk its  own funds or otherwise incur personal  financial
liability  in the performance of its  duties if the Indenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.

DEFEASANCE

   
    The Indenture provides  that, except as  may be provided  in respect of  any
series of Subordinated Debt Securities, the provisions of Article Fourteen shall
apply  to the  Subordinated Debt  Securities of any  series and  the Company may
elect either to  (a) except in  respect of any  Subordinated Debt Securities  to
which  a NWPS Trust  or a trustee  of such trust  is the holder,  defease and be
discharged from any and all obligations  with respect to such Subordinated  Debt
Securities  (except for the obligation  to pay Additional Amounts,  if any, to a
holder who is not a United States  person upon the occurrence of certain  events
of tax, assessment or
    

                                       38

governmental   charge  with  respect  to  payments  on  such  Subordinated  Debt
Securities and the  obligations to  register the  transfer or  exchange of  such
Subordinated Debt Securities, to replace temporary or mutilated, destroyed, lost
or  stolen  Subordinated Debt  Securities, to  maintain an  office or  agency in
respect of such Subordinated Debt Securities, and to hold moneys for payment  in
trust)  ("Defeasance") or (b)  be released from its  obligations with respect to
such Subordinated Debt Securities under Section 1402 or, if provided pursuant to
Section 1403  of  the Indenture,  its  obligations  with respect  to  any  other
covenant,  and any omission to comply with such obligations shall not constitute
a default  or  an  Event of  Default  with  respect to  such  Subordinated  Debt
Securities ("covenant defeasance"), in either case, upon the irrevocable deposit
by  the Company  with the  Indenture Trustee  (or other  qualifying trustee), in
trust, of an amount, in such Currency in which such Subordinated Debt Securities
are then specified as payable at Stated Maturity, or Government Obligations  (as
defined  below), or both, applicable to  such Subordinated Debt Securities (with
such applicability being determined on the basis of the currency, currency  unit
or  composite  currency  in which  such  Subordinated Debt  Securities  are then
specified as payable at Stated Maturity) which through the scheduled payment  of
principal  and interest in accordance with their  terms will provide money in an
amount sufficient to pay the principal of (and premium, if any) and interest, if
any, on such  Subordinated Debt Securities,  and any mandatory  sinking fund  or
analogous payments thereon, on the scheduled due dates therefor.

    Such a trust may only be established if, among other things, the Company has
delivered  to the Indenture Trustee  an Opinion of Counsel  (as specified in the
Indenture) to the effect that the  Holders of such Subordinated Debt  Securities
will  not recognize income,  gain or loss  for United States  federal income tax
purposes as  a result  of such  defeasance or  covenant defeasance  and will  be
subject  to United States  federal income tax  on the same  amounts, in the same
manner and at the same times as would  have been the case if such defeasance  or
covenant defeasance had not occurred; provided that, such Opinion of Counsel, in
the case of defeasance under clause (a) above, must refer to and be based upon a
revenue  ruling of the Internal Revenue Service or a change in applicable United
States federal income tax law occurring after the date of the Indenture.

    "Government Obligations" means securities that are (i) direct obligations of
the  government  that  issued  the  Currency  in  which  the  Subordinated  Debt
Securities of a particular series are payable, for the payment of which its full
faith  and credit  is pledged,  or (ii)  obligations of  a person  controlled or
supervised by and acting as an agency or instrumentality of the government  that
issued the Currency in which the Subordinated Debt Securities of such series are
payable,  the payment of which is unconditionally guaranteed as a full faith and
credit obligation by  the United  States of  America or  such other  government,
which,  in either  case, are  not callable  or redeemable  at the  option of the
issuer thereof, and shall also include a depository receipt issued by a bank  or
trust  company as custodian with respect to  any such Government Obligation or a
specific payment of interest on or  principal of any such Government  Obligation
held  by such custodian for  the account of the  holder of a depository receipt;
provided that (except as  required by law) such  custodian is not authorized  to
make  any deduction  from the  amount payable to  the holder  of such depository
receipt from any amount received by  the custodian in respect of the  Government
Obligation or the specific payment of interest in or principal of the Government
Obligation evidenced by such depository receipt.

    Unless  otherwise  provided  in  the Prospectus  Supplement,  if,  after the
Company has deposited funds and/or  Government Obligations to effect  defeasance
or  covenant  defeasance  relating  thereto with  respect  to  Subordinated Debt
Securities of any series, (a) the Holder of a Subordinated Debt Security of such
series is entitled to and does elect, pursuant to the terms of such Subordinated
Debt Security, to receive payment  in a currency other  than that in which  such
deposit  has been made in respect of  such Subordinated Debt Security or (b) the
currency in which such deposit has been made in respect of any Subordinated Debt
Security of such series ceases  to be used by  its government of issuance,  then
the  indebtedness represented by such Subordinated Debt Security shall be deemed
to have been, and will be, fully discharged and satisfied through the payment of
the  principal  of  (and  premium,  if  any)  and  interest,  if  any,  on  such
Subordinated  Debt Security as  they become due  out of the  proceeds yielded by
converting the amount so deposited in respect of such Subordinated Debt Security
into  the   Currency  in   which  such   Subordinated  Debt   Security   becomes

                                       39

payable  as a result  of such election or  such cessation of  usage based on the
applicable Market Exchange  Rate. Unless  otherwise provided  in the  Prospectus
Supplement,  all payments of principal of (and premium, if any) and interest, if
any, and Additional Amounts, if any,  on any Subordinated Debt Security that  is
payable  in  a Foreign  Currency that  ceases to  be used  by its  government of
issuance shall be made in U. S. Dollars.

   
    In the event the Company effects covenant defeasance with respect to (i) any
Subordinated Debt Securities and any related coupons and (ii) such  Subordinated
Debt  Securities are declared due  and payable because of  the occurrence of any
Event of Default, other than the Event  of Default described in clause (iii)  or
(v)  under "Events of Default," with respect to any covenant for which there has
been defeasance, the Currency and/or Government Obligations on deposit with  the
Indenture  Trustee will  be sufficient to  pay amounts due  on such Subordinated
Debt Securities at the time of their  Stated Maturity but may not be  sufficient
to  pay amounts  due on  such Subordinated  Debt Securities  at the  time of the
acceleration resulting from such  Event of Default.  However, the Company  would
remain liable to make payment of such amounts due at the time of acceleration.
    

    The  Prospectus  Supplement may  further  describe the  provisions,  if any,
permitting such defeasance or  covenant defeasance, including any  modifications
to  the  provisions  described  above, with  respect  to  the  Subordinated Debt
Securities of or within a particular series and any related coupons.

MISCELLANEOUS

    The Company will have the right at all times to assign any of its respective
rights or obligations under the Indenture  to a direct or indirect  wholly-owned
subsidiary  of the Company; provided, that, in the event of any such assignment,
the Company will remain liable for all of their respective obligations.  Subject
to the foregoing, the Indenture will be binding upon and inure to the benefit of
the  parties thereto and their respective  successors and assigns. The Indenture
provides that it may not otherwise be assigned by the parties thereto.

                    DESCRIPTION OF THE PREFERRED SECURITIES

    Each NWPS Trust may issue, from time  to time, only one series of  Preferred
Securities having terms described in the Prospectus Supplement relating thereto.
The  Declaration of each NWPS Trust authorizes the Regular Trustees of such NWPS
Trust to issue on behalf of such NWPS Trust one series of Preferred  Securities.
The Declaration will be qualified as an indenture under the Trust Indenture Act.
The   Preferred  Securities  will  have  such  terms,  including  distributions,
redemption, voting, liquidation  rights and  such other  preferred, deferred  or
other  special  rights  or  such  restrictions as  shall  be  set  forth  in the
Declaration or made part of the Declaration by the Trust Indenture Act.

    Reference is made  to the  Prospectus Supplement relating  to the  Preferred
Securities  of a  NWPS Trust for  specific terms, including  (i) the distinctive
designation  of  such  Preferred  Securities,  (ii)  the  number  of   Preferred
Securities  issued by  such NWPS Trust,  (iii) the annual  distribution rate (or
method of determining such  rate) for Preferred Securities  issued by such  NWPS
Trust  and the  date or  dates upon  which such  distributions shall  be payable
(provided, however, that,  distributions on such  Preferred Securities shall  be
payable  on a quarterly  basis to holders  of such Preferred  Securities as of a
record  date  in  each  quarter  during  which  such  Preferred  Securities  are
outstanding),  (iv) whether distributions on Preferred Securities issued by such
NWPS Trust shall be cumulative, and, in the case of Preferred Securities  having
such  cumulative distribution rights, the date or dates or method of determining
the date or  dates from which  distributions on Preferred  Securities issued  by
such  NWPS Trust shall be  cumulative, (v) the amount  or amounts which shall be
paid out of the assets of such NWPS Trust to the holders of Preferred Securities
of such  NWPS Trust  upon voluntary  or involuntary  dissolution, winding-up  or
termination  of such NWPS Trust, (vi) the obligation, if any, of such NWPS Trust
to purchase or  redeem Preferred Securities  issued by such  NWPS Trust and  the
price  or prices at which, the period or  periods within which and the terms and
conditions upon which Preferred  Securities issued by such  NWPS Trust shall  be
purchased  or redeemed, in whole or in  part, pursuant to such obligation, (vii)
the voting rights, if any, of Preferred Securities issued by such NWPS Trust  in
addition  to those required by law, including  the number of votes per Preferred
Security and any

                                       40

requirement for  the approval  by the  holders of  Preferred Securities,  or  of
Preferred  Securities  issued  by one  or  more NWPS  Trusts  or of  both,  as a
condition to specified  action or  amendments to  the Declaration  of such  NWPS
Trust,   and  (viii)   any  other  relevant   rights,  preferences,  privileges,
limitations or restrictions of  Preferred Securities issued  by such NWPS  Trust
consistent  with the Declaration of such NWPS Trust, or with applicable law. All
Preferred Securities offered  hereby will be  guaranteed by the  Company to  the
extent  set forth  below under "Description  of the  Guarantees." Certain United
States federal income tax considerations applicable to any offering of Preferred
Securities will be described in the Prospectus Supplement relating thereto.

    In connection with  the issuance  of Preferred Securities,  each NWPS  Trust
will  issue one series of Common Securities.  The Declaration of each NWPS Trust
authorizes the Regular Trustees of  each trust to issue  on behalf of such  NWPS
Trust one series of Common Securities having such terms including distributions,
redemption,  voting, liquidation  rights or  such restrictions  as shall  be set
forth therein. The terms of the Common Securities issued by a NWPS Trust will be
substantially identical to the terms of the Preferred Securities issued by  such
NWPS  Trust and the Common Securities will rank pari passu, and payments will be
made thereon pro rata with the  Preferred Securities except that, upon an  event
of  default  under the  Declaration, the  rights  of the  holders of  the Common
Securities to payment in respect of distributions and payments upon liquidation,
redemption and otherwise will  be subordinated to the  rights of the holders  of
the  Preferred Securities. Except  in certain limited  circumstances, the Common
Securities will also carry the right to  vote and to appoint, remove or  replace
any of the NWPS Trustees of a NWPS Trust. All of the Common Securities of a NWPS
Trust will be directly or indirectly owned by the Company.

                         DESCRIPTION OF THE GUARANTEES

    Set  forth below is a summary  of information concerning the Guarantees that
will be executed and delivered  by the Company for  the benefit of the  holders,
from  time to time, of Preferred Securities. Each Guarantee will be qualified as
an indenture under the Trust Indenture Act. Wilmington Trust Company will act as
indenture trustee under each Guarantee  (the "Guarantee Trustee"). The terms  of
each  Guarantee will be those set forth in each Guarantee and those made part of
each Guarantee by the Trust  Indenture Act. The summary  does not purport to  be
complete  and is subject in all respects  to the provisions of, and is qualified
in its entirety by  reference to, the  form of Guarantee, which  is filed as  an
exhibit to the Registration Statement of which this Prospectus forms a part, and
the  Trust Indenture Act. Each  Guarantee will be held  by the Guarantee Trustee
for the benefit  of the holders  of the Preferred  Securities of the  applicable
NWPS Trust.

GENERAL

   
    Pursuant to each Guarantee, the Company will irrevocably and unconditionally
agree,  to the extent  set forth herein,  to pay in  full to the  holders of the
Preferred Securities issued by a NWPS Trust, the Guarantee Payments (as  defined
herein)  (except  to the  extent  paid by  such NWPS  Trust),  as and  when due,
regardless of any  defense, right  of set-off  or counterclaim  which such  NWPS
Trust  may  have or  assert. The  following payments  with respect  to Preferred
Securities issued by a NWPS Trust (the "Guarantee Payments"), to the extent  not
paid  by such NWPS Trust will be subject to the Guarantee (without duplication):
(i) any accrued and unpaid  distributions that are required  to be paid on  such
Preferred  Securities, to the extent the Company  has made a payment of interest
or principal on  the Subordinated  Debt Securities, (ii)  the redemption  price,
including  all accrued and  unpaid distributions to the  date of redemption (the
"Redemption Price"), to the extent the Company has made a payment of interest or
principal on the  Subordinated Debt  Securities, with respect  to any  Preferred
Securities  called for redemption by such NWPS Trust, and (iii) upon a voluntary
or involuntary dissolution, winding-up or termination of such NWPS Trust  (other
than  in connection with the distribution of Subordinated Debt Securities to the
holders of  Preferred Securities  or  the redemption  of  all of  the  Preferred
Securities  upon the maturity or redemption of the Subordinated Debt Securities)
the lesser of (a) the  aggregate of the liquidation  amount and all accrued  and
unpaid  distributions on such Preferred Securities to the date of payment to the
extent such NWPS Trust has funds  legally available therefor and (b) the  amount
of   assets  of  such  NWPS  Trust   remaining  available  for  distribution  to
    

                                       41

holders of such  Preferred Securities  in liquidation  of such  NWPS Trust.  The
Company's  obligation to  make a  Guarantee Payment  may be  satisfied by direct
payment of  the required  amounts by  the Company  to the  holders of  Preferred
Securities or by causing such NWPS Trust to pay such amounts to such holders.

   
    Each  Guarantee will be  a full and unconditional  guarantee with respect to
the Preferred Securities issued  by the applicable NWPS  Trust from the time  of
issuance  of such  Preferred Securities  but will  not apply  to any  payment of
distributions due  to  the extent  such  NWPS  Trust shall  lack  funds  legally
available  therefor as a result of a failure  by the Company to make payments of
interest or principal on the Subordinated  Debt Securities. If the Company  does
not make interest payments on the Subordinated Debt Securities purchased by such
NWPS  Trust,  such  NWPS  Trust  will not  pay  distributions  on  the Preferred
Securities issued by  a NWPS  Trust and will  not have  funds legally  available
therefor. See "Description of the Subordinated Debt Securities."
    

   
    The  Company  and  NWPS  Capital  believe  that  the  above  mechanisms  and
obligations,  taken  together,  are  substantially  equivalent  to  a  full  and
unconditional  guarantee  by  the  Company  of  payments  due  on  the Preferred
Securities.
    

    The Company has also agreed to irrevocably and unconditionally guarantee the
obligations of  the NWPS  Trusts  with respect  to  the Common  Securities  (the
"Common  Securities Guarantee")  to the  same extent  as the  Guarantees, except
that, upon  an  event of  default  under  the Indenture,  holders  of  Preferred
Securities  under  the Guarantees  shall have  priority  over holders  of Common
Securities under the Common Securities Guarantees with respect to  distributions
and payments on liquidation, redemption or otherwise.

CERTAIN COVENANTS OF THE COMPANY

    In  each Guarantee, the Company will covenant that, so long as any Preferred
Securities issued  by the  applicable NWPS  Trust remain  outstanding, if  there
shall  have occurred any event  that would constitute an  event of default under
such Guarantee or the Declaration of such NWPS Trust, then (a) the Company shall
not declare or pay any dividend on, or make any distribution with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any  of
its  capital stock and (b)  the Company shall not  make any payment of interest,
principal or  premium,  if any,  on  or repay,  repurchase  or redeem  any  debt
securities  issued by the Company  which rank pari passu  with or junior to such
Subordinated Debt  Securities.  However, each  Guarantee  will except  from  the
foregoing any stock dividends paid by the Company where the dividend stock is of
the same as that on which the dividend is being paid.

MODIFICATION OF THE GUARANTEES; ASSIGNMENT

   
    Except  with respect to any changes  that do not materially adversely affect
the rights of holders  of Preferred Securities  (in which case  no vote will  be
required),  each Guarantee may  be amended only  with the prior  approval of the
holders of  not less  than 66  2/3%  in liquidation  amount of  the  outstanding
Preferred  Securities  issued  by  the  applicable  NWPS  Trust.  The  manner of
obtaining any such approval of holders of such Preferred Securities will be  set
forth  in an accompanying  Prospectus Supplement. All  guarantees and agreements
contained in  a  Guarantee  shall bind  the  successors,  assignees,  receivers,
trustees  and representatives of the  Company and shall inure  to the benefit of
the holders  of the  Preferred  Securities of  the  applicable NWPS  Trust  then
outstanding.
    

EVENTS OF DEFAULT

    An  Event of Default under the Guarantee  will occur upon the failure of the
Company to perform  any of  its payments  or other  obligations thereunder.  The
holders of a majority in liquidation amount of the Preferred Securities to which
a  Guarantee relates  have the  right to  direct the  time, method  and place of
conducting any proceeding for any remedy  available to the Guarantee Trustee  in
respect  of  the Guarantee  or  to direct  the exercise  of  any trust  or power
conferred upon the Guarantee Trustee under the Guarantee.

   
    If the Guarantee  Trustee fails  to enforce  such Guarantee,  any holder  of
Preferred Securities relating to such Guarantee may, after such holder's written
request  to the  Guarantee Trustee to  enforce the Guarantee,  institute a legal
proceeding directly  against  the Company  to  enforce the  Guarantee  Trustee's
rights under such Guarantee without first instituting a legal proceeding against
the relevant NWPS Trust, the Guarantee Trustee or any other person or entity.
    

                                       42

    The  Company will be required to provide annually to the Guarantee Trustee a
statement as to  the performance by  the Company of  certain of its  obligations
under each of the Guarantees and as to any default in such performance.

    The  Company  is required  to file  annually with  the Guarantee  Trustee an
officer's certificate as to the  Company's compliance with all conditions  under
each of the Guarantees.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

    The  Guarantee Trustee, prior to the  occurrence of a default, undertakes to
perform only such  duties as are  specifically set forth  in the Guarantee  and,
after  default with respect  to a Guarantee,  shall exercise the  same degree of
care as a prudent  individual would exercise  in the conduct of  his or her  own
affairs. Subject to such provision, the Guarantee Trustee is under no obligation
to  exercise any  of the  powers vested in  it by  a Guarantee  Agreement at the
request of any holder  of Preferred Securities unless  it is offered  reasonable
indemnity  against the  costs, expenses and  liabilities that  might be incurred
thereby.

TERMINATION OF THE GUARANTEES

    Each Guarantee will terminate as to  the Preferred Securities issued by  the
applicable NWPS Trust upon full payment of the Redemption Price of all Preferred
Securities  of  the  NWPS  Trust, upon  distribution  of  the  Subordinated Debt
Securities held by the NWPS Trust to the holders of the Preferred Securities  of
such  NWPS Trust, or upon full payment of the amounts payable in accordance with
the Declaration of  such NWPS Trust  upon liquidation of  such NWPS Trust.  Each
Guarantee  will continue to be effective or  will be reinstated, as the case may
be, if at any time any holder  of Preferred Securities issued by the  applicable
NWPS Trust must restore payment of any sums paid under such Preferred Securities
or such Guarantee.

STATUS OF THE GUARANTEES

    Each  Guarantee will constitute  an unsecured obligation  of the Company and
will rank  (i)  subordinate  and  junior  in  right  of  payment  to  all  other
liabilities  of the Company, (ii)  pari passu with the  most senior preferred or
preference stock now or hereafter issued  by the Company and with any  guarantee
now  or hereafter  entered into by  the Company  in respect of  any preferred or
preference stock  of any  affiliate of  the  Company, and  (iii) senior  to  the
Company's  common stock. The terms of the Preferred Securities provide that each
holder of Preferred  Securities issued  by a  NWPS Trust  by acceptance  thereof
agrees  to  the  subordination  provisions and  other  terms  of  the applicable
Guarantee.

    Each Guarantee will constitute a guarantee of payment and not of  collection
(allowing  the guaranteed party to institute a legal proceeding directly against
the guarantor to  enforce its  rights under  a Guarantee  without instituting  a
legal proceeding against any other person or entity).

GOVERNING LAW

    The  Guarantee  will be  governed by  and construed  in accordance  with the
internal laws of the State of New York.

                        DESCRIPTION OF THE COMMON STOCK

GENERAL

   
    Under the Company's Restated Certificate  of Incorporation, as amended  (the
"Charter"),  the Company is authorized to  issue three classes of capital stock:
300,000 shares of Cumulative Preferred Stock, par value $100 per share, of which
26,000 shares of 4 1/2% Cumulative Preferred  Stock and 40,000 shares of 5  1/4%
Cumulative  Preferred Stock are outstanding; 200,000 shares of Preference Stock,
par value $50 per share, none of which are outstanding; and 20,000,000 shares of
Common Stock, par value $3.50 per share, 7,677,232 of which were outstanding  as
of  June 8, 1995. The Cumulative Preferred Stock and the Preference Stock may be
issued at any time by the Board of  Directors in such series with such terms  as
it may fix in resolutions providing for the issuance thereof.
    

    The following statements are summaries of certain provisions relating to the
Common  Stock  contained  in  the Charter,  the  Company's  First  Mortgage Bond
Indenture, as supplemented to date (the "1940 Indenture"), and the Company's New
Mortgage  (the   1940   Indenture   and   the   New   Mortgage   Indenture   are

                                       43

referred  to together as the "Bond Indentures"). Such summaries are not complete
descriptions of the provisions  of the Charter and  the Bond Indentures and  are
qualified  in  their entirety  by reference  thereto. The  Charter and  the Bond
Indentures are  contained in  exhibits to  reports and  registration  statements
which have been filed with the Commission (see "Available Information").

DIVIDEND RIGHTS

    Subject  to  the limitations  described in  the following  three paragraphs,
dividends may be paid  on the Common  Stock out of  funds legally available  for
that purpose, when and as declared by the Company's Board of Directors.

   
    The Company may not declare or pay cash dividends on the Common Stock unless
full  dividends on  all Cumulative Preferred  Stock and on  any Preference Stock
then outstanding for the  current and all past  quarterly dividend periods  have
been  paid or provided for. Also, dividends on  the Common Stock may not be paid
unless the Company  has complied with  all sinking fund  requirements for  those
series  of the  Cumulative Preferred Stock  and any Preference  Stock which have
such requirements.
    

   
    Under the  terms  of  the Charter,  for  so  long as  shares  of  Cumulative
Preferred  Stock are outstanding, the following  dividend limitations may not be
exceeded unless  authorized by  the  holders of  two-thirds of  the  outstanding
shares  of such stock: dividends (other  than dividends payable in Common Stock)
and other distributions on, or acquisitions by the Company for value of,  Common
Stock  (a) may not exceed  50% of the Company's  Net Income Available for Common
Stock for the preceding  12-months' period if the  "common stock equity" of  the
Company  is less than 20% of "total capitalization" (each calculated as required
by the  Charter)  and  (b) may  not  exceed  75%  of such  Net  Income  if  such
capitalization  ratio is 20% or  more but less than  25%. If such capitalization
ratio is 25%  or more, no  such dividend, distribution  or acquisition shall  be
declared,  paid or  effected which  would reduce  such ratio  to less  than 25%,
except to  the  extent permitted  by  clauses (a)  and  (b). Pursuant  to  these
provisions,  at  March 31,  1995, retained  earnings were  not restricted  as to
availability for cash dividends  on the Common Stock  and the Company's  "common
stock equity" was 47% of its "total capitalization".
    

   
    The  Bond Indentures and  certain purchase agreements  relating to presently
outstanding Cumulative  Preferred Stock  contain  covenants limiting  the  funds
available  for payment of  cash dividends and other  distributions on the Common
Stock (for payment as well as purchases  of Common Stock by the Company).  Under
the  most restrictive of  existing covenants in  the Bond Indentures  or in such
purchase agreements, at March 31, 1995, a total of approximately $46,271,000 was
available for cash dividends  on the Common Stock.  In addition, under the  1940
Indenture  cash dividends on the Common Stock  and purchases of Common Stock may
be made only if the aggregate  amount expended for maintenance and provided  for
depreciation  by  the Company  subsequent to  January 1,  1946, plus  Net Income
Available for Common Stock earned after  December 31, 1945, which remains  after
such dividend (or purchase) is equal to not less than the total of 3 1/2% of the
fixed  tangible property, plant and equipment of the Company for each full year,
and a proportionate percentage for any fractional year, which shall have elapsed
between January 1, 1946, and the date of such proposed action.
    

VOTING RIGHTS

    Of the three classes of the  Company's authorized capital stock, the  Common
Stock  is the general voting stock. Holders  of Common Stock are entitled to one
vote for each share held. Except in  the case of certain dividend arrearages  on
the Cumulative Preferred Stock or Preference Stock, the Common Stock is the only
class of stock entitled to be voted for the election of directors.

LIQUIDATION RIGHTS

    In  the  event  of  a  liquidation  (whether  voluntary  or  involuntary) or
reduction in the Company's  capital resulting in any  distribution of assets  to
its  stockholders, the holders of the Common  Stock are entitled to receive, pro
rata according to the number  of shares held by each,  all of the assets of  the
Company  remaining  for  distribution  after  payment  to  the  holders  of  the
Cumulative Preferred Stock and Preference Stock of the full preferential amounts
to which they are entitled.

                                       44

CERTAIN OTHER FEATURES

    Holders of Common Stock do not have any preemptive right to subscribe to  or
acquire any additional stock or other securities issued by the Company.

TRANSFER AGENTS AND REGISTRARS

    The  Transfer Agent  and Registrars for  the Common Stock  are Norwest Bank,
Minnesota, and the Company.

PROVISIONS WITH POSSIBLE ANTI-TAKEOVER EFFECTS

    The Company's Charter currently provides for the classification of the Board
of Directors into three classes. The Charter limits the number of directors that
may be elected to  not less than  nine nor more than  twelve (exclusive of  such
number  of Directors  as may be  elected by any  class of shares  of the Company
other than  the Common  Stock on  account of  specified dividend  arrearages  in
accordance  with  the  Charter) and  provides  that  vacancies on  the  Board of
Directors are to be filled by a majority vote of directors and that directors so
chosen shall hold office until  the end of the full  term of the class in  which
the  vacancy occurred. A vote of the holders of 75% of the Company's outstanding
voting stock  is required  to amend  these provisions.  In addition,  under  the
Charter  and the Delaware General Corporation  Law, directors of the Company may
only be  removed for  cause. Removal  for cause  must be  approved by  either  a
majority  vote  of directors  (excluding the  director  or directors  subject to
removal) or by a  vote of the holders  of at least a  majority of the  Company's
outstanding voting stock.

    In  addition, the  "fair price provisions"  of Charter  require that certain
proposed business combinations  between the Company  and any person  who is  the
beneficial  owner  of more  than 10%  of  the outstanding  voting shares  of the
Company (an "interested party") must  be approved by the  holders of 75% of  the
voting  shares, unless certain fair price and procedural requirements are met or
the business combination is  approved by a  majority of "Continuing  Directors,"
those directors who were elected prior to the time a person became an interested
person  and any other  director so designated  by such directors.  A vote of the
holders of 75% of  the Company's outstanding voting  stock is required to  amend
the fair price provisions.

fixed public offering price or at varying prices determined at the time of sale.
The Offered Securities may be offered to the public either through  underwriting

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    The By-Laws of  the Company provide  for indemnification by  the Company  of
each  of its directors and officers to  the fullest extent permitted by Delaware
law for liability (including liability arising under the Securities Act of 1933)
of such director or officer arising by reason of his or her status as a director
or officer of the Company, provided that he or she met the standards established
in the By-Laws, which include  requirements that he or  she acted in good  faith
and  in a  manner he  or she  reasonably believed  to be  in the  Company's best
interest. The Company will also advance  expenses prior to final disposition  of
an  action, suit or proceeding upon receipt of an undertaking by the director or
officer to repay  such amount  if the  director or  officer is  not entitled  to
indemnification.  All rights to indemnification  and advancement of expenses are
deemed to be a contract between the Company and its directors and officers.  The
determination  that a director  or officer has met  the standards established in
the By-Laws  may  be  made  by  a  majority  vote  of  a  quorum  consisting  of
disinterested  directors, an opinion of counsel  (if no such quorum is available
or even  if attainable,  a  quorum of  disinterested  directors so  directs),  a
majority  vote of stockholders, or  a court (which may  also overturn any of the
preceding determinations).

    The Declaration of each NWPS Trust provides that no NWPS Trustee,  affiliate
of  any  NWPS  Trustee,  or  any  officers,  directors,  shareholders,  members,
partners, employees,  representatives or  agents  of any  NWPS Trustee,  or  any
employee  or agent of  such NWPS Trust  or its affiliates  (each an "Indemnified
Person") shall be liable, responsible or accountable in damages or otherwise  to
such  NWPS Trust or any employee or agent of the trust or its affiliates for any
loss, damage or claim  incurred by reason  of any act  or omission performed  or
omitted  by such Indemnified person  in good faith on  behalf of such NWPS Trust
and in a  manner such Indemnified  Person reasonably believed  to be within  the
scope  of the authority conferred on such Indemnified Person by such Declaration
or by law, except that an Indemnified Person shall be liable for any such  loss,
damage or claim incurred by reason of such Indemnified Person's gross negligence
(or, in the case of the Property Trustee, negligence) or willful misconduct with
respect  to such  acts or  omissions. The  Declaration of  each NWPS  Trust also
provides that to  the fullest extent  permitted by applicable  law, the  Company
shall  indemnify and hold harmless each  Indemnified Person from and against any
loss, damage or claim incurred by such  Indemnified Person by reason of any  act
or  omission performed or  omitted by such  Indemnified Person in  good faith on
behalf of such  NWPS Trust and  in a manner  such Indemnified Person  reasonably
believed  to  be within  the scope  of authority  conferred on  such Indemnified
Person by such Declaration, except that no Indemnified Person shall be  entitled
to    be   indemnified   in    respect   of   any    loss,   damage   or   claim

                                      II-1

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. (CONTINUED)
incurred by such Indemnified  Person by reason of  gross negligence (or, in  the
case  of the Property Trustee, negligence) or willful misconduct with respect to
such acts or  omissions. The  Declaration of  each NWPS  Trust further  provides
that,  to the  fullest extent permitted  by applicable  law, expenses (including
legal fees) incurred by  an Indemnified Person in  defending any claim,  demand,
action,  suit or proceeding shall, from time to time, be advanced by the Company
prior to the final disposition of such claim, demand, action, suit or proceeding
upon receipt by or an undertaking by  or on behalf of the Indemnified Person  to
repay  such amount if it shall be  determined that the Indemnified Person is not
entitled to be indemnified for the  underlying cause of action as authorized  by
the Declaration of such NWPS Trust.

    The  directors and officers of the Company  and the Regular Trustees of each
NWPS Trust  are  covered  by insurance  policies  indemnifying  against  certain
liabilities,  including certain liabilities arising  under the Securities Act of
1933, as amended (the "Securities Act"), which might be incurred by them in such
capacities and against which they cannot  be indemnified by the Company or  such
NWPS Trust.

    Any  agents, dealers or underwriters who execute any of the agreements filed
as Exhibit  1  to  this  registration statement  will  agree  to  indemnify  the
Company's  directors and their officers and the NWPS Trustees of each NWPS Trust
who signed the registration statement against certain liabilities that may arise
under the Securities Act with respect to information furnished to the Company or
such NWPS Trust by or on behalf of any such indemnifying party.

ITEM 16. LIST OF EXHIBITS.
    The exhibits filed herewith are set  forth on the Exhibit Index included  as

ITEM 17. UNDERTAKINGS.
    Each of the undersigned registrants hereby undertakes:

ITEM 17. UNDERTAKINGS. (CONTINUED)
        (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 purposes of determining any liability under the Securities
    Act  of 1933 each filing of the  Company's annual report pursuant to section
    13(a) or section 15(d) of the  Securities Exchange Act of 1934, as  amended,
    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.

        (5) For purposes of determining  any liability under the Securities  Act
    of  1933, the information omitted from the  form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h)  under the  Securities Act  shall be  deemed to  be part  of  this
    registration statement as of the time it was declared effective.

        (6)  For the purpose  of determining any  liability under the Securities
    Act  of  1933,  each  post-effective  amendment  that  contains  a  form  of
    prospectus  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.

    NWPS  Capital  Financing  I,  NWPS Capital  Financing  II  and  NWPS Capital
Financing III, who are some of  the registrants, hereby undertake to provide  to
the  underwriter specified in the  underwriting agreements, certificates in such
denominations and registered  in such names  as required by  the underwriter  to
permit prompt delivery to each purchaser.

    Insofar  as indemnification for liabilities arising under the Securities Act
of 1933, as  amended, may be  permitted to directors,  officers and  controlling
persons  of  the  registrants pursuant  to  the statutory  and  bylaw provisions
referred to in Item 15, or otherwise, the registrants have been advised that  in
the  opinion of the  Securities and Exchange  Commission such indemnification is
against public policy as expressed in such Act and is therefore,  unenforceable.
In  the event that  a claim for indemnification  against such liabilities (other
than the payment by the registrants of expenses incurred or paid by a  director,
officer  or controlling person  of the registrants 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
registrants will,  unless in  the opinion  of its  counsel the  matter has  been
settled  by controlling precedent, submit to a court of appropriate jurisdiction
the question whether  such indemnification  by it  is against  public policy  as
expressed  in such Act  and will be  governed by the  final adjudication of such
issue.
