     Re:  Northwestern Public Service Company - Consent to Amendment to
1940
Indenture and Agreement to Exchange Bonds

Ladies and Gentlemen:

     We refer to:

     (i)  the Indenture dated August 1, 1940 (as the same has been amended
from time to time, the "1940 Indenture") by and between Northwestern Public
Service Company (the "Company") and The Chase Manhattan Bank (National
Association), successor to The Chase National Bank of the City of New York
(the "1940 Trustee"), and C. J. Heinzelmann, successor to Carl E. Buckley
(the 1940 Trustee and said C. J. Heinzelmann being hereinafter called the
"1940 Trustees");

     (ii) the Supplemental Indenture dated November 1, 1989 by and between
the Company and the 1940 Trustees, pursuant to which the Company issued
$7,500,000 of its First Mortgage Bonds, 8.90% Series due 1999 (the "8.90%
Bonds") to Metropolitan Life Insurance Company ("Metropolitan Life");

     (iii)     the Supplemental Indenture dated July 15, 1991 by and
between the Company and the 1940 Trustees, pursuant to which the Company
issued $15,000,000 of its First Mortgage Bonds, 8.824% Series due 1998 (the
"8.824% Bonds"), $11,000,000 of which were issued to The Travelers
Insurance Company ("Travelers") and the remaining $4,000,000 of which were
issued to The Phoenix Insurance Company ("Phoenix");

     (iv) the Supplemental Indenture dated September 1, 1992 by and between
the Company and the 1940 Trustees, pursuant to which the Company issued
$25,000,000 of its First Mortgage Bonds, 6.99% Series due 2002 (the "6.99%
Bonds"), $22,000,000 of which were issued to Travelers and the remaining
$3,000,000 of which were issued to The Travelers Indemnity Company
("Indemnity"); and

     (v)  the Supplemental Indenture dated August 15, 1993 by and between
the Company and the 1940 Trustees, pursuant to which the Company issued
$55,000,000 of its First Mortgage Bonds, 7% Series due 2023 (the "7%
Bonds") to The Chase Manhattan Bank (National Association), as Trustee (the
"1993 Trustee") under the General Mortgage Indenture and Deed of Trust
dated as of August 1, 1993 (the "1993 Indenture") by and between the
Company and the 1993 Trustee.

     Unless otherwise defined herein, the terms defined in the 1940
Indenture shall be used herein as therein defined.

     As of the date of this letter, the only Bonds outstanding under the
1940 Indenture are the 8.90% Bonds, the 8.824% Bonds, the 6.99% Bonds and
the 7% Bonds, and the only holders of the Bonds are Metropolitan Life,
Travelers, Phoenix, Indemnity and the 1993 Trustee (collectively, the
"Bondholders").

     The Company has advised the Bondholders that it desires to enter into
a Supplemental Indenture with the 1940 Trustees pursuant to which the
Company would issue up to $75,000,000 of Bonds (the "New 1940 Bonds") to
the 1993 Trustee to be used as "Pledged Bonds" under the 1993 Indenture for
purposes of issuing to the public a like amount of bonds ("New Mortgage
Bonds") under the 1993 Indenture (the "Public Offering").  At present, the
Company is not able to issue the full amount of New 1940 Bonds under the
1940 Indenture, because of (a) the limitation in Section 3 of Article II of
the 1940 Indenture that it may issue Bonds pursuant to such Section only to
the extent in principal amount of sixty percent (60%) of all "net
expenditures" (as defined in such Section), and (b) the prohibition in
Section 3 of Article II of the 1940 Indenture on using as the basis for the
issuance of Bonds any expenditures for property which has previously been
used by the Company to satisfy its maintenance and renewal fund obligations
under Article VII of the 1940 Indenture.

     The undersigned Bondholders have agreed (a) to consent to the
amendment of Section 3 of Article II to the 1940 Indenture (i) to increase
the percentage stated therein from sixty percent (60%) to seventy-five
percent (75%), and (ii) to eliminate the restriction regarding the use of
expenditures for property that has been used to satisfy the Company's
obligations under Article VII of the 1940 Indenture, pursuant to a
Supplemental Indenture to the 1940 Indenture in substantially the form of
Exhibit A attached hereto, and (b) in the case of Metropolitan Life,
Travelers, Phoenix and Indemnity (collectively, the "Exchanging
Bondholders"), to exchange the Bonds held by each of them for bonds of like
tenor to be issued pursuant to a Supplemental Indenture to the 1993
Indenture in substantially the form of Exhibit B-1, Exhibit B-2 or Exhibit
B-3 (as applicable), in each case so long as the Company agrees to the
conditions and other provisions set forth herein.

     1.   Accordingly, the Company and the undersigned Bondholders
(including the 1993 Trustee) hereby agree as follows:

          (a)  The actions set forth in clause (b) of this Paragraph 1
     shall be effective as if the same had taken place at a meeting of
     Bondholders pursuant to Article XVIII (Meetings of Bondholders) of the
     1940 Indenture (which provision was added to the 1940 Indenture by the
     Supplemental Indenture dated October 1, 1946), and the undersigned
     Bondholders hereby waive any and all notice of a meeting of the
     Bondholders provided for in said Article XVIII; and

          (b)  The undersigned Bondholders hereby consent to the execution
     by the Company and the 1940 Trustees of the Supplemental Indenture to
     the 1940 Indenture in substantially the form of Exhibit A attached
     hereto, and the recording and filing thereof in the various
     jurisdictions in which the 1940 Indenture is recorded or filed.

     2.   The Company and the Exchanging Bondholders hereby agree as
follows:

          (a)  On a date not later than the last to occur of September 1,
     1995 or the date of the Public Offering, the Company will issue:

                    (i)  to Metropolitan Life, and Metropolitan Life will
          accept, one or more bonds in the aggregate principal amount of
          $7,500,000 in exchange for all of the issued and outstanding
          8.90% Bonds, which bonds shall bear interest at a rate of 8.90%
          per annum, shall mature on November 1, 1999, and shall be issued
          pursuant to a Supplemental Indenture to the 1993 Indenture in
          substantially the form of Exhibit B-1 attached hereto (as the
          same may be modified by mutual agreement of the Company and
          Metropolitan Life) and afforded the benefits set forth therein;

                    (ii) to Travelers, and Travelers will accept, one or
          more bonds in the aggregate principal amount of $11,000,000 in
          exchange for a like amount of 8.824% Bonds held by it, and to
          Phoenix, and Phoenix will accept, one or more bonds in the
          aggregate principal amount of $4,000,000 in exchange for a like
          amount of 8.824% Bonds held by it, in each case which bonds shall
          bear interest at a rate of 8.824% per annum, shall mature on July
          15, 1998, and shall be issued pursuant to a Supplemental
          Indenture to the 1993 Indenture in substantially the form of
          Exhibit B-2 attached hereto (as the same may be modified by
          mutual agreement of the Company, Travelers and Phoenix) and
          afforded the benefits set forth therein; and

                    (iii)     to Travelers, and Travelers will accept, one
          or more bonds in the aggregate principal amount of $22,000,000 in
          exchange for a like amount of 6.99% Bonds held by it, and to
          Indemnity, and Indemnity will accept, one or more bonds in the
          aggregate principal amount of $3,000,000 in exchange for a like
          amount of 6.99% Bonds held by it, in each case which bonds shall
          bear interest at a rate of 6.99% per annum, shall mature on
          September 1, 2002, and shall be issued pursuant to a Supplemental
          Indenture to the 1993 Indenture in substantially the form of
          Exhibit B-3 attached hereto (as the same may be modified by
          mutual agreement of the Company, Travelers and Indemnity) and
          afforded the benefits set forth therein.

     The bonds to be issued under the 1993 Indenture and the Supplemental
     Indentures thereto pursuant to this clause (a) are referred to herein
     as the "Exchanged Bonds."

          (b)  At the time of the issue of the Exchanged Bonds pursuant to
     clause (a) of this Paragraph 2, each of the Exchanging Bondholders
     will surrender their respective Bonds in exchange for the Exchanged
     Bonds (which shall be stated to accrue interest from the date of the
     last interest payment date of the Bonds to be exchanged for the
     Exchanged Bonds), subject to satisfaction of the following conditions:

                    (i)  Each Exchanging Bondholder shall have received an
          opinion of counsel from Schiff Hardin & Waite in substantially
          the form (mutatis mutandis) of the opinion delivered pursuant to
          Paragraph 9(b) (or in the case of the Exchanged Bonds issued in
          exchange for the 8.90% Bonds, Paragraph 10(b)) of the Bond
          Purchase Agreements pursuant to which the Bonds were issued to
          such Exchanging Bondholder;

                    (ii) Each Exchanging Bondholder shall have received an
          opinion of counsel from local counsel in the States of South
          Dakota and Nebraska in substantially the form (mutatis mutandis)
          of the opinions delivered pursuant to Paragraph 9(c) (or in the
          case of the Exchanged Bonds issued in exchange for the 8.90%
          Bonds, Paragraph 10(c)) of the Bond Purchase Agreements pursuant
          to which the Bonds were issued to such Exchanging Bondholder;

                    (iii)     Each Exchanging Bondholder shall have
          received an officer's certificate in substantially the form
          (mutatis mutandis) of the officer's certificate delivered
          pursuant to Paragraph 9(d) (or in the case of the Exchanged Bonds
          issued in exchange for the 8.90% Bonds, Paragraph 10(d)) of the
          Bond Purchase Agreements pursuant to which the Bonds were issued
          to such Exchanging Bondholder, which officer's certificate shall
          also include a representation by the Company to the effect that
          the issuance of the Exchanged Bonds and the compliance by the
          Company with the provisions thereof will not involve any
          prohibited transaction within the meaning of ERISA or Section
          4975 of the Internal Revenue Code;

                    (iv) Each Exchanging Bondholder shall be satisfied with
          the proceedings taken on or before the date of the exchange in
          connection with the transactions contemplated by this Paragraph
          2, and with the form and substance of all instruments applicable
          to the issuance of the Exchanged Bonds;

                    (v)  The exchange shall, on the date of the exchange,
          be permitted by the laws and regulations of all jurisdictions to
          which each Exchanging Bondholder is then subject, and each
          Exchanging Bondholder shall have received such factual
          certificates, signed by officers of the Company, or such other
          evidence as it may request to establish compliance with this
          condition; and

                    (vi) The obligation of each Exchanging Bondholder to
          surrender its respective Bonds is subject to the surrender by
          each of the other Exchanging Bondholders of their Bonds.

          (c)  Concurrently with the issuance of the Exchanged Bonds in
     accordance with clause (a) of this Paragraph 2 and the surrender of
     the Bonds in accordance with clause (b) of this Paragraph 2, the
     Company will deliver to the 1993 Trustee the "Company Order" and the
     other documents and instruments referred to in Section 7.07 of the
     1993 Indenture for purposes of causing the 1993 Trustee to surrender
     for cancellation to the 1940 Trustees all of the Pledged Bonds
     (including the 7% Bonds and the New 1940 Bonds) then held by the 1993
     Trustee.

          (d)  Promptly following the surrender by the 1993 Trustee of the
     Pledged Bonds in accordance with clause (c) of this Paragraph 2, the
     Company will deliver (i) to the 1940 Trustees the request of the
     Company and the other documents and instruments referred to in Article
     XII of the 1940 Indenture for purposes of causing the 1940 Trustees to
     cancel and discharge the lien of the 1940 Indenture as provided for in
     said Article XII, and (ii) to the Exchanging Bondholders a certificate
     to the effect that the 1940 Mortgage has been cancelled and
     discharged, together with an opinion of counsel from Schiff Hardin &
     Waite to the same effect.

     3.   As further consideration for the agreement of the Exchanging
Bondholders to the consent to the amendment to the 1940 Indenture, the
exchange of the Bonds for the Exchanged Bonds and the other matters
provided for herein, the Company agrees that each Exchanging Bondholder (or
its respective successors or assigns), with respect to the Exchanged Bonds
then held by it, shall have the following rights, in addition to the rights
provided for in the 1993 Indenture and the Supplemental Indentures pursuant
to which the Exchanged Bonds were issued:

          (a)  If, at any time subsequent to the earlier of (i) the date
     which is 120 days following the issuance of New Mortgage Bonds
     pursuant to the S-3 Registration Statement filed by the Company on
     June 21, 1995, as the same may be amended or supplemented, or (ii)
     January 1, 1996, an Exchanging Bondholder gives written notice to the
     Company (specifying that it is being given pursuant to this clause
     (a)) requesting the Company to file a registration statement to
     register under the 1933 Act all (but not less than all) of a series of
     Exchanged Bonds owned by the requesting person (provided, however,
     that (1) in the event that such request is made with respect to the
     Exchanged Bonds to be issued in exchange for the 8.824% Bonds, such
     request shall be submitted by both Travelers and Phoenix, and (2) in
     the event that such request is made with respect to the Exchanged
     Bonds to be issued in exchange for the 6.99% Bonds, such request shall
     be submitted by both Travelers and Indemnity), then the Company shall
     promptly notify each of the other Exchanging Bondholders of such
     request.  Within 15 days after receipt by any such other Exchanging
     Bondholder of notice of such request, it may notify the Company that
     it too requests that all (but not less than all) of a series of
     Exchanged Bonds owned by such Exchanging Bondholder be included in
     such registration (all of the Exchanging Bondholders who at that point
     have requested the Company to include their Exchanged Bonds in the
     registration being hereinafter referred to as the "Selling
     Bondholders"); provided, however, that the failure by an Exchanging
     Bondholder to make such a request shall not preclude such Exchanging
     Bondholder from subsequently exercising its rights under this
     Paragraph 3.  The Company shall then use its best efforts to cause to
     be registered under the 1933 Act all Exchanged Bonds that the Selling
     Bondholders have so requested to be registered.  Notwithstanding the
     foregoing, the Company shall not be obligated to effect a registration
     pursuant to this clause (a) during the period starting with the date
     45 days prior to the Company's estimated date of filing of, a
     registration statement pertaining to an underwritten public offering
     of New Mortgage Bonds for the account of the Company, provided that
     the Company is actively employing in good faith all reasonable efforts
     to cause such registration statement to become effective and that the
     Company's estimate of the date of filing such registration statement
     is made in good faith.  The Company shall be obligated to effect one
     registration pursuant to this clause (a) for each series of Exchanged
     Bonds.  At any time prior to the effectiveness of the registration
     statement, any request for registration under this clause (a) may be
     withdrawn by a Selling Bondholder, whereupon, if such withdrawal
     affects all of the Exchanged Bonds that were to be the subject of the
     registration statement, the Company shall either not file or withdraw
     the filing of the registration statement, as applicable, and such
     withdrawal of the request for registration will not be deemed to have
     been the exercise of the registration right granted in this clause
     (a).

          (b)  Whenever under clause (a) of this Paragraph 3 the Company is
     to use its best efforts to effect the registration of any Exchanged
     Bonds, that shall require the Company to do the following:

                    (i)  As expeditiously as reasonably possible (and in
          any event within 30 days following the delivery to the Company of
          the request by the first Selling Bondholder pursuant to clause
          (a) of this Paragraph 3), prepare and file with the Securities
          and Exchange Commission ("SEC," which term includes any successor
          agency) a registration statement with respect to such Exchanged
          Bonds, and use its best efforts to cause such registration
          statement to become and remain effective under the 1933 Act,
          except that the Company shall in no event be obligated to cause
          any such registration to remain effective for more than nine
          months.

                    (ii) As expeditiously as reasonably possible, prepare
          and file with the SEC such amendments and supplements to such
          registration statement and the prospectus used in connection with
          such registration statement as may be necessary to comply with
          the provisions of the 1933 Act with respect to the disposition of
          all securities covered by such registration statement.

                    (iii)     As expeditiously as reasonably possible,
          furnish to each Selling Bondholder such numbers of the copies of
          the prospectus used in connection with such registration
          statement (including all preliminary prospectuses and the final
          prospectus), and all amendments and supplements thereto, and such
          other documents as they may reasonably request in order to
          facilitate the distribution of the Exchanged Bonds owned by such
          Selling Bondholder.

                    (iv) As expeditiously as reasonably possible, make a
          commercially reasonable effort to register and qualify the
          securities covered by such registration statement under such
          securities or Blue Sky laws of such jurisdictions as shall be
          reasonably appropriate or requested by each Selling Bondholder or
          by the underwriter (if any) for the distribution of the
          securities covered by the registration statement, except that the
          Company shall not be required in connection therewith or as a
          condition thereto to qualify to do business or to file a general
          consent to service of process in any such jurisdiction, and
          except that (anything in this letter to the contrary
          notwithstanding with respect to the bearing of expenses) if any
          jurisdiction in which the Exchanged Bonds shall be qualified
          shall require that expenses incurred in connection with the
          registration or qualification of the Exchanged Bonds in that
          jurisdiction be borne by those selling the Exchanged Bonds, then
          such expenses shall be payable by the Selling Bondholders pro
          rata in accordance with the principal amount of the Exchanged
          Bonds being registered, to the extent required by such
          jurisdiction.

                    (v)  Advise each Selling Bondholder promptly after the
          Company shall receive notice or obtain knowledge thereof of (1)
          the issuance of any stop order by the SEC suspending the
          effectiveness of such registration statement or the initiation or
          threatening of any proceeding for that purpose, (2) any similar
          action by any regulatory agency of competent jurisdiction under
          the securities or Blue Sky laws of any jurisdiction, and in any
          such case promptly make a commercially reasonable effort to
          prevent the issuance of any stop order or the taking of any such
          similar action or to obtain its withdrawal if such stop order
          shall be issued or any such similar action shall be taken, and
          (3) the happening of any event as a result of which the
          prospectus included in such registration statement contains an
          untrue statement of material fact or omits to state any fact
          necessary to make the statements therein not misleading.

                    (vi) Furnish to each Selling Bondholder copies of all
          documents proposed to be filed with respect to any amendment or
          supplement to such registration statement or prospectus at a
          reasonable time prior to such filing, and not file any such
          amendment or supplement to which the Selling Bondholders of a
          majority of the Exchanged Bonds covered by such registration
          statement shall have reasonably objected on the grounds that such
          amendment or supplement does not comply in all material respects
          with the requirements of the 1933 Act or the rules and
          regulations thereunder, unless in the opinion of counsel for the
          Company the filing of such amendment or supplement is reasonably
          necessary to protect the Company from any liabilities under any
          applicable federal or state law and such filing will not violate
          applicable law.

                    (vii)     Furnish on the effective date of the
          registration statement and, if such registration includes an
          underwritten public offering, at the closing provided for in the
          underwriting agreement: (1) an opinion, dated each such date, of
          the counsel representing the Company for the purposes of such
          registration, addressed to the underwriters, if any, and to the
          Selling Bondholders participating in such registration, stating
          that such registration statement has become effective under the
          1933 Act and that (A) to the best of such counsel's knowledge, no
          stop order suspending the effectiveness thereof has been issued
          and no proceedings for that purpose have been instituted or are
          pending or contemplated under the 1933 Act, (B) the registration
          statement, related prospectus and each amendment or supplement
          thereto comply as to form in all material respects with the
          requirements of the 1933 Act and the applicable rules and
          regulations of the SEC thereunder (except that such counsel need
          express no opinion as to financial statements and financial data
          contained therein), (C) such counsel have no reason to believe
          that the registration statement, the prospectus or any amendment
          or supplement thereto contains any untrue statement of a material
          fact or omits to state a material fact required to be stated
          therein or necessary to make the statements therein, in the light
          of circumstances under which they were made, not misleading
          (except that such counsel need express no belief as to the
          financial statements and financial data contained therein, nor as
          to any of the information provided by the Selling Bondholders
          pursuant to clause (c) of this Paragraph 3), (D) the description
          in the registration statement or prospectus or any amendment or
          supplement thereto of all legal and governmental proceedings and
          all contracts and other legal documents or instruments filed as

          dated each such date, from the independent certified public
          accountants of the Company, addressed to the underwriters, if
          any, and to the Selling Bondholders participating in such
          registration, covering such matters as such underwriters and such
          Selling Bondholders may reasonably request, in which letter such
          accountants shall state (without limiting the generality of the
          foregoing) that they are independent certified public accountants
          within the meaning of the 1933 Act and that in the opinion of
          such accountants the financial statements and other financial
          data of the Company included in the registration statement or the
          prospectus or any amendment or supplement thereto comply in all
          material respects with the applicable accounting requirements of
          the 1933 Act and applicable rules and regulations thereunder.

                    (viii)    Enter into such customary agreements and take
          all such other actions as the Selling Bondholders that are
          holders of a majority of the Exchanged Bonds covered by such
          registration statement or the managing underwriters for such
          registration, if any, may reasonably request in order to
          facilitate the distribution of such Exchanged Bonds (including,
          without limitation, to cause such Exchanged Bonds to be listed on
          such securities exchange on which similar securities issued by
          the Company are then listed, to cause such Exchanged Bonds to be
          eligible for quotation and transaction reporting through an
          automated inter-dealer quotation system operated by a national
          securities association, and to provide a transfer agent and
          registrar).

                    (ix) Make available for inspection by, and cause the
          Company's officers, directors, employees and independent
          accountants to supply to, any Selling Bondholder, any underwriter
          participating in the distribution pursuant to such registration
          statement, and any attorney, accountant or other agent for any
          thereof, all financial and other records of the Company and all
          information reasonable requested in connection with such
          registration statement.

                    (x)  Enter into an indemnity agreement pursuant to
          which the Company agrees (to the extent permitted by law) to
          indemnify and hold harmless each Selling Bondholder, each of its
          directors, officers, employees and agents, each underwriter (if
          any), each other person who participates in the offering of such
          Exchanged Bonds, and each other person, if any, who controls
          (within the meaning of the 1933 Act) such Selling Bondholder,
          underwriter or participating person, against any losses, claims,
          damages or liabilities, joint or several, to which such Selling
          Bondholder, director, officer, employee, agent, underwriter,
          participating person or controlling person may become subject
          under the 1933 Act or any other statute or at common law, insofar
          as such losses, claims, damages or liabilities (or actions in
          respect thereof) arise out of or are based upon (A) any alleged
          untrue statement of any material fact contained, on the effective
          date thereof, in any registration statement under which such
          Exchanged Bonds were registered under the 1933 Act, any
          preliminary prospectus or final prospectus contained therein, or
          any summary prospectus issued in connection with any Exchanged
          Bonds being registered, or any amendment or supplement thereto,
          or (B) any alleged omission to state in any such document a
          material fact required to be stated therein or necessary to make
          the statements therein not misleading, and shall reimburse such
          Selling Bondholders, director, officer, employee, agent,
          underwriter, participating person or controlling person for any
          legal or other expenses reasonably incurred by such Selling
          Bondholder, director, officer, employee, agent, underwriter,
          participating person or controlling person in connection with
          investigating or defending any such loss, damage, liability or
          action; provided, however, that the Company shall not be liable
          to such Selling Bondholder, director, officer, employee, agent,
          underwriter, participating person or controlling person in any
          such case to the extent that any such loss, claim, damage or
          liability arises out of or is based upon any alleged untrue
          statement or alleged omission made in such registration
          statement, preliminary prospectus, final prospectus, summary
          prospectus or amendment or supplement thereto in reliance upon
          and in conformity with written information furnished to the
          Company by such Selling Bondholder, specifically for use therein.
          Such indemnity agreement shall contain customary provisions with
          respect to the procedure to be followed in connection with the
          assertion of any right to indemnification, as well as customary
          provisions with respect to just and equitable contribution in the
          event where any such indemnity is unavailable.

          (c)  It shall be a condition precedent to the obligations of the
     Company to take any action pursuant to this Paragraph 3 that each
     Selling Bondholder shall furnish to the Company such information
     regarding such Selling Bondholder, the Exchanged Bonds held by such
     Selling Bondholder, and the intended method of disposition of such
     Exchanged Bonds (which may, but need not, involve an underwritten
     transaction) as the Company shall reasonably request and as shall be
     required in connection with the action to be taken by the Company.

          (d)  All expenses incurred in connection with a registration
     pursuant to clause (a) of this Paragraph 3 (excluding underwriters'
     discounts and commissions (if any), fees of any counsel which the
     Selling Bondholder may separately engage and expenses expressly
     required by clause (b)(iv) of this Paragraph 3 to be paid by the
     Selling Bondholders), including without limitation all registration
     and qualification fees, printers' and accounting fees, fees and
     disbursements of counsel for the Company, internal expenses of the
     Company (including, without limitation, salaries of officers and
     employees) and listing fees shall be borne by the Company.

          (e)  In the event that, for any reason other than the failure by
     a Selling Bondholder to comply with the provisions of this Paragraph
     3, the registration statement provided for in clause (a) of this
     Paragraph 3 is not declared effective by the SEC within 90 days
     following the filing thereof pursuant to clause (b)(i) of this
     Paragraph 3, the Company shall be obligated to pay to each Selling
     Bondholder a fee equal to fifteen basis points (.15%) per annum
     (calculated on the basis of a 360-day year) of the principal amount of
     the Exchanged Bonds owned by such Selling Bondholder that are subject
     to such registration statement for the period beginning on the 90th
     day following the filing of such registration statement and ending on
     the earlier of (i) the date that such registration statement is
     declared effective by the SEC, or (ii) the date on which the Exchanged
     Bonds with respect to which the fee applies are paid in full by the
     Company.  The fee provided for under this clause (e) shall be payable
     semi-annually in arrears on the date on which interest on the
     Exchanged Bonds is due and payable and on the last day of the period
     referred to in the preceding sentence.

          (f)  For purposes of this Paragraph 3:  (i) the term "1933 Act"
     means the Securities Act of 1933, as amended; and (ii) the terms
     "register," "registered" and "registration" refer to a registration
     effected by filing a registration statement in compliance with the
     1933 Act (a "registration statement") and such registration statement
     becoming effective under the 1933 Act.

     In order to induce the Bondholders to execute and deliver this letter,
     the Company represents and warrants to the Bondholders that:

          (a)  This letter is the legal, valid and binding obligation of
     the Company, enforceable against the Company in accordance with its
     terms, except as may be limited by bankruptcy, insolvency or similar
     laws affecting the enforcement of creditors rights in general and by
     general principles of equity;

          (b)  No "default" or "event of default" (as such terms are
     defined in the 1940 Indenture) or "Event of Default" (as such term is
     defined in the 1993 Indenture) exists, in each case both before and
     after giving effect to the consents and other matters contemplated
     hereby; and

          (c)  Upon the discharge of the lien of the 1940 Indenture in
     accordance with clause (d) of Paragraph 2, the lien of the 1993
     Indenture on the property formerly subject to the lien of the 1940
     Indenture, to the extent the same is part of the "Mortgaged Property"
     under the 1993 Indenture, will be subject to no lien prior to the lien
     of the 1993 Indenture except "Permitted Liens" under the 1993
     Indenture and liens of the character permitted to exist or to be
     created under Section 6.06 of the 1993 Indenture.

     Nothing contained in this letter shall affect in any manner the
Company's obligations under the Bond Purchase Agreements pursuant to which
the 8.90% Bonds, the 8.824% Bonds or the 6.99% Bonds, respectively, were
issued, except to the extent that any such obligations relate to the "New
Bonds" or the "Indenture" (as such terms are defined in such Bond Purchase
Agreements), in which case such obligations shall relate to the applicable
series of Exchanged Bonds and the 1993 Indenture (mutatis mutandis),
respectively, and such Bond Purchase Agreements shall otherwise remain in
full force and effect.

     This letter shall be construed and enforced as an agreement in
accordance with, and the rights of the parties shall be governed by, the
law of the State of New York (without giving effect to principles of
conflicts of law).

     This letter may be executed by the parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed
to be an original and all of which taken together shall constitute but one
and the same instrument.

     If you are in agreement with the foregoing, please sign the form of
acceptance on the enclosed counterpart of this letter and return the same
to the Company, whereupon this letter shall become a binding agreement
among you and the Company.

                              Very truly yours,

                              NORTHWESTERN PUBLIC SERVICE COMPANY

August 1, 1993, hereinafter mentioned, the post office address of which is
4 Chase MetroTech Center, 3rd Floor, Brooklyn, New York 11245;

     Whereas, the Company has heretofore executed and delivered its General
Mortgage Indenture and Deed of Trust dated as of August 1, 1993 (the

Company issued and to be issued thereunder (the "Bonds"); and

     Whereas, the Company has heretofore executed and delivered to the
Trustee a certain indenture supplemental to the Original Indenture dated
August 15, 1993 (the Original Indenture, as supplemented and amended by the
aforementioned supplemental indenture and by this Supplemental Indenture
being hereinafter referred to as the "Indenture"); and

     Whereas, the Company desires to create a new series of Bonds to be
issued under the Indenture, to be known as New Mortgage Bonds, 8.90% Series
due 1999 (the "New Mortgage Bonds of the 8.90% Series"), which New Mortgage
Bonds of the 8.90% Series are to be issued in exchange for certain other
bonds of the Company of like tenor and amount that were issued pursuant to
a supplemental indenture to the Company's Indenture dated August 1, 1940;
and

     Whereas, the Company, in the exercise of the powers and authority
conferred upon and reserved to it under the provisions of the Indenture,
and pursuant to appropriate resolutions of the Board of Directors, has duly
resolved and determined to make, execute and deliver to the Trustee a
Supplemental Indenture in the form hereof for the purposes herein provided;
and

     Whereas, all conditions and requirements necessary to make this
Supplemental Indenture a valid, binding and legal instrument have been
done, performed and fulfilled and the execution and delivery hereof have
been in all respects duly authorized;

     Now, Therefore, This Indenture Witnesseth:

Bonds as follows:

     Article I
     Description Of Bonds Of The 8.90% Series Due 1999

     Section 1.  The Company hereby creates a new series of Bonds to be
known as "New Mortgage Bonds, 8.90% Series due 1999."  The New Mortgage
Bonds of the 8.90% Series shall be executed, authenticated and delivered in
accordance with the provisions of, and shall in all respects be subject to,
all of the terms, conditions and covenants of the Indenture, as
supplemented and modified.

     The commencement of the first interest period for the New Mortgage
Bonds of the 8.90% Series shall be May 1, 1995.  The New Mortgage Bonds of
the 8.90% Series shall mature November 1, 1999, and shall bear interest at
the rate of 8.90% per annum, payable semi-annually on the first day of May
and the first day of November in each year; provided, however, that if the
Company shall default in the payment of principal of, premium, if any, or
interest on, any New Mortgage Bond of the 8.90% Series when the same shall
have become due and such default shall continue for more than five days,
then the Company covenants and agrees that it will pay to the holder
thereof, to the extent permitted by applicable law, interest on the
outstanding principal amount of such New Bond at the rate of 9.90% per
annum commencing on the due date of such payment and continuing until such
overdue amount is paid.  The person in whose name any of the New Mortgage
Bonds of the 8.90% Series are registered at the close of business on any
record date (as hereinafter defined) with respect to any interest payment
date shall be entitled to receive the interest payable on such interest
payment date notwithstanding the cancellation of such New Mortgage Bonds of
the 8.90% Series upon any transfer or exchange subsequent to the record
date and prior to such interest payment date; provided, however, that if
and to the extent the Company shall default in the payment of the interest
due on such interest payment date, such defaulted interest shall be paid as
provided in Section 3.07(b) of the Indenture.

     The term "record date" as used in this Section with respect to any
interest payment date shall mean April 15 or October 15, as the case may
be, next preceding the semi-annual interest payment date, or, if such April
15 or October 15 shall be a legal holiday or a day on which banking
institutions in the Borough of Manhattan, The City of New York, State of
New York, are authorized by law to close, then the next preceding day which
shall not be a legal holiday or a day on which such institutions are so
authorized to close.

     Section 2.  The New Mortgage Bonds of the 8.90% Series shall be issued
only as registered Bonds without coupons of the denomination of $1,000, or
any integral multiple of $1,000, appropriately numbered.  The New Mortgage
Bonds of the 8.90% Series may be exchanged, upon surrender thereof, at the
agency of the Company in the Borough of Manhattan, The City of New York,
State of New York, for one or more new New Mortgage Bonds of the 8.90%
Series of other authorized denominations, for the same aggregate principal
amount, subject to the terms and conditions set forth in the Indenture.

     New Mortgage Bonds of the 8.90% Series may be exchanged or transferred
without expense to the registered owner thereof except that any taxes or
other governmental charges required to be paid with respect to such
transfer or exchange shall be paid by the registered owner requesting such
transfer or exchange as a condition precedent to the exercise of such
privilege.

     Section 3.  The New Mortgage Bonds of the 8.90% Series and the
Trustee's Certificate of Authentication shall be substantially in the
following forms respectively:

discharged as provided in the Indenture hereinafter mentioned; provided,
however, that if the Company shall default in the payment of principal of,
premium, if any, or interest on, this Bond when the same shall have become

                    [FORM OF REVERSE OF BOND]

     This New Mortgage Bond of the 8.90% Series is one of a duly authorized
issue of Bonds of the Company (the "Bonds"), of the series hereinafter
specified, all issued and to be issued under and equally secured by a
General Mortgage Indenture and Deed of Trust (the "Indenture"), dated as of

all indentures supplemental thereto reference is hereby made for a
description to the properties mortgaged and pledged, the nature and extent
of the security, the rights of registered owners of the Bonds and of the
Trustee in respect thereof, and the terms and conditions upon which the
Bonds are, and are to be, secured.  The Bonds may be issued in series, for
various principal sums, may mature at different times, may bear interest at
different rates and may otherwise vary as provided in the Indenture.  This
New Mortgage Bond of the 8.90% Series is one of a series designated as the
"New Mortgage Bonds, 8.90% Series Due 1999" (the "New Mortgage Bonds of the
8.90% Series") of the Company issued under and secured by the Indenture and
described in the supplemental indenture dated as of __________, 1995 (the
"Supplemental Indenture dated as of __________, 1995"), between the Company
and the Trustee, supplemental to the Indenture.

     New Mortgage Bonds of the 8.90% Series, of which this is one, are
subject to redemption as follows:

          At the option of the Company and upon the notice and in the
     manner and with the effect provided in the Indenture, any or all
     of the New Mortgage Bonds of the 8.90% Series may be redeemed by
     the Company at any time and from time to time prior to maturity,
     upon payment of the Yield Maintenance Price (as defined in
     Section 1 of Article III of the Supplemental Indenture dated as
     of __________, 1995) for each of the New Mortgage Bonds of the
     8.90% Series to be redeemed, together in each case with principal
     and accrued interest to the redemption date.

     To the extent permitted by, and as provided in, the Indenture,
modifications or alterations of the Indenture, or of any indenture
supplemental thereof, and of the rights and obligations of the Company and
of the holders of the Bonds may be made with the consent of the Company by
an affirmative vote of the holders of a majority in aggregate principal
amount of the Bonds entitled to vote then outstanding, at a meeting of the
holders of the Bonds called and held as provided in the Indenture, and by
an affirmative vote of the holders of a majority in aggregate principal
amount of the Bonds of any series or any tranche or tranches of any series
entitled to vote then outstanding and affected by such modification or
alteration, in case one or more but less than all of the series of Bonds or
of any tranche or tranches of any series of Bonds then outstanding under
the Indenture are so affected; provided, however, that no such modification
or alteration shall be made which will affect the terms of payment of the
principal of, or interest or premium, if any, on this Bond.

     In case an Event of Default, as defined in the Indenture, shall occur,
the principal of all the New Mortgage Bonds of the 8.90% Series at any such
time outstanding under the Indenture may be declared or may become due and
payable, upon the conditions and in the manner and with the effect provided
in the Indenture.  The Indenture provides that such declaration may be
rescinded under certain circumstances.

                           Article II
        Issue Of New Mortgage Bonds Of The 8.90% Series

     Section 1.  The Company hereby exercises the right to obtain the
authentication of $7,500,000 principal amount of Bonds pursuant to the
terms of Section 4.03 of the Indenture.  All such Bonds shall be New
Mortgage Bonds of the 8.90% Series.

     Section 2.  Such New Mortgage Bonds of the 8.90% Series may be
authenticated and delivered prior to the filing for recordation of this
Supplemental Indenture.

                          Article III
                           Redemption

     Section 1.  The New Mortgage Bonds of the 8.90% Series shall, upon the
notice and in the manner and with the effect provided in Article Five of
the Original Indenture, as amended by Section 2 of this Article III, be
redeemable at any time and from time to time prior to maturity, at the
option of the Company, as a whole, upon payment of the Yield Maintenance
Price (as hereinafter defined) for each of the New Mortgage Bonds of the
8.90% Series to be redeemed, together with accrued interest to the
redemption date; provided however, the Company shall not redeem any New
Mortgage Bonds of the 8.90% Series in a principal amount less than $100,000
or a multiple thereof.

     If the notice of redemption shall have been given by the Company as
provided in the Indenture, the Computing Holder shall deliver written
notice to the Company on the fifth business day prior to such redemption
date, of the amount of the Yield Maintenance Price for the principal amount
of the New Mortgage Bonds of the 8.90% Series held by such Computing Holder
so to be redeemed, which notice shall set forth in reasonable detail the
computation thereof.  The Yield Maintenance Price set forth in such notice
shall be binding on the Company absent manifest error.

     The Company shall deliver to each holder of the New Mortgage Bonds of
the 8.90% Series to be redeemed on or before such redemption date a
certificate signed by a principal financial officer of the Company setting
forth the Yield Maintenance Price of the principal amount of the New
Mortgage Bonds of the 8.90% Series held by such holder so to be redeemed,
and setting forth in reasonable detail the calculation thereof accompanied
by a copy of the written notice given by the Computing Holder which sets
forth the computation of the Yield Maintenance Price of the New Mortgage
Bonds of the 8.90% Series held by the Computing Holder.  The Company
covenants and agrees that it will on such redemption date redeem the New
Mortgage Bonds of the 8.90% Series held by each holder so to be redeemed by
payment to such holder the Yield Maintenance Price therefor, together with
interest accrued thereon to the date fixed for redemption.

     As used in this Section 1:

     "Computing Holder" shall mean the holder who holds bonds of the New
Mortgage Bonds of the 8.90% Series with an aggregate principal amount
outstanding higher than that of New Mortgage Bonds of the 8.90% Series held
by any other holder, or in the event two or more holders hold an equal
amount which constitutes the highest principal amount of the New Mortgage
Bonds of the 8.90% Series, any holder designated by the other holders.  For
purposes of determining the Computing Holder, the New Mortgage Bonds of the
8.90% Series then held by Metropolitan Life Insurance Company and its
subsidiaries shall be aggregated.

     "Weighted Average Life to Final Maturity" of any of the New Mortgage
Bonds of the 8.90% Series to be redeemed, shall mean the number of years
(rounded to the nearest one-twelfth of a year) which will elapse between
the scheduled date of redemption thereof and the scheduled date of maturity
of the New Mortgage Bonds of the 8.90% Series.

     "Yield Maintenance Price" shall mean the higher of (1) the entire
unpaid principal amount of the New Mortgage Bonds of the 8.90% Series to be
redeemed and (2) the sum of the respective Payment Values of each
prospective interest payment and the principal payment as maturity in
respect of the principal amount of the New Mortgage Bonds of the 8.90%
Series to be redeemed (the amount of each such payment being herein
referred to as a "Payment").  The Payment Value of each Payment shall be
determined by discounting such Payment at the Reinvestment Rate, for the
period from the scheduled date on which such Payment is due to be made to
the applicable date of redemption.  The Reinvestment Rate is the yield
which shall be imputed from the yields of those actively traded "On The
Run" United States Treasury securities having maturities as close as
practicable to the Weighted Average Life to Final Maturity of the New
Mortgage Bonds of the 8.90% Series to be redeemed.  The yields of such
United States Treasury securities shall be determined as of 10 A.M. Eastern
Time on the date on which the Yield Maintenance Price is determined.

     Section 2.  Notice of redemption of any New Mortgage Bonds of the
8.90% Series shall be given as provided in Section 5.04 of the Original
Indenture.  If given by mail, the mailing of such notice shall be a
condition precedent to redemption, provided that any notice which is mailed
in the manner provided in Section 5.04 of the Original Indenture shall be
conclusively presumed to have been duly given whether or not the holders
receive such notice, and failure to give such notice by mall, or any defect
in such notice, to the holder of any such bond designated for redemption
shall not affect the validity of the redemption of any other such bond.
Except for the changes in the giving of notice of redemption as provided in
this Section, the procedures for redemption of the New Mortgage Bonds of
the 8.90% Series shall be as provided in Article Five of the Original
Indenture.

     Section 3.  The Company, with the approval of the Trustee, may enter
into a written agreement with the holder of any New Mortgage Bonds of the
8.90% Series providing that payment of such bonds called for redemption in
part only be made directly by mail, wire transfer or in any other manner to
the holder thereof without presentation or surrender thereof if there shall
be delivered to the Trustee an agreement (which may be a composite with
other such agreements) between the Company and such holder (or other person
acting as agent for such holder or for whom such holder is a nominee) that
payment shall be so made, and that in the event the holder thereof shall
sell or transfer any such bonds (a) it will, prior to the delivery of such
bonds, either (i) surrender such bonds to the Trustee to make a proper
notation of the amount of principal paid thereon or (ii) surrender such
bonds to the Trustee against receipt of one or more New Mortgage Bonds of
the 8.90% Series in an aggregate principal amount equal to the unpaid
principal portion of the bonds so surrendered, and (b) it will promptly
notify the Company of the name and address of the transferee of any New
Mortgage Bonds of the 8.90% Series so transferred.  The Trustee shall not
be liable or responsible to any such holder or transferee or to the Company
or to any other person for any act or omission to act on the part of the
Company or any such holder in connection with any such agreement.  The
Company will indemnify and save the Trustee harmless against any liability
resulting from any such act or omission and against any liability resulting
from any action taken by the Trustee in accordance with the provisions of
any such agreement.

                                Article IV
                                The Trustee

     The Trustee hereby accepts the trusts hereby declared provided, and
agrees to perform the same upon the terms and conditions in the Indenture
set forth and upon the following terms and conditions:

          The Trustee shall not be responsible in any manner
     whatsoever for or in respect of the validity or sufficiency of
     this Supplemental Indenture or the due execution hereof by the
     Company or for or in respect of the recitals contained herein,
     all of which recitals are made by the Company solely.  In
     general, each and every term and condition contained in Article
     Eleven of the Indenture shall apply to this Supplemental
     Indenture with the same force and effect as if the same were
     herein set forth in full, with such omissions, variations and
     modifications thereof as may be appropriate to make the same
     conform to this Supplemental Indenture.

                                Article VI
                         Miscellaneous Provisions


     This Supplemental Indenture may be simultaneously executed in any
number of counterparts, each of which when so executed shall be deemed to
be an original; but such counterparts shall together constitute but one and
the same instrument.

     In Witness Whereof, said Northwestern Public Service Company has

payment shall be so made, and that in the event the holder thereof shall
sell or transfer any such bonds (a) it will, prior to the delivery of such

                         [FORM OF REVERSE OF BOND]

     This New Mortgage Bond of the 6.99% Series is one of a duly authorized
issue of Bonds of the Company (the "Bonds"), of the series hereinafter
specified, all issued and to be issued under and equally secured by a
General Mortgage Indenture and Deed of Trust (the "Indenture"), dated as of
August 1, 1993, executed by the Company to The Chase Manhattan Bank
(National Association) (the "Trustee"), as Trustee, to which Indenture and
all indentures supplemental thereto reference is hereby made for a
description to the properties mortgaged and pledged, the nature and extent
of the security, the rights of registered owners of the Bonds and of the
Trustee in respect thereof, and the terms and conditions upon which the
Bonds are, and are to be, secured.  The Bonds may be issued in series, for
various principal sums, may mature at different times, may bear interest at
different rates and may otherwise vary as provided in the Indenture.  This
New Mortgage Bond of the 6.99% Series is one of a series designated as the
"New Mortgage Bonds, 6.99% Series Due 2002" (the "New Mortgage Bonds of the
6.99% Series") of the Company issued under and secured by the Indenture and
described in the supplemental indenture dated as of __________, 1995 (the
"Supplemental Indenture dated as of __________, 1995"), between the Company
and the Trustee, supplemental to the Indenture.

     New Mortgage Bonds of the 6.99% Series, of which this is one, are
subject to redemption as follows:

     (I)  At the option of the Company and upon the notice and in the
manner and with the effect provided in the Indenture, all, but not less
than all, of the New Mortgage Bonds of the 6.99% Series may be redeemed by
the Company at any time, on or after September 1, 1997 and prior to
maturity, upon payment of the Make-Whole Amount (as defined in Section 1 of
Article III of the Supplemental Indenture dated as of __________, 1995) for
each of the New Mortgage Bonds of the 6.99% Series to be redeemed, together
in each case with principal and accrued interest to the redemption date.

     (II) New Mortgage Bonds of the 6.99% Series shall be redeemed by the
Company in the amounts required by the Supplemental Indenture dated as of
__________, 1995 on September 1 of each year, commencing in 1998, through
the operation of the sinking fund for such bonds, upon payment of the
principal amount thereof together with accrued interest to the redemption
date.

     To the extent permitted by, and as provided in, the Indenture,
modifications or alterations of the Indenture, or of any indenture
supplemental thereof, and of the rights and obligations of the Company and
of the holders of the Bonds may be made with the consent of the Company by
an affirmative vote of the holders of a majority in aggregate principal
amount of the Bonds entitled to vote then outstanding, at a meeting of the
holders of the Bonds called and held as provided in the Indenture, and by
an affirmative vote of the holders of a majority in aggregate principal
amount of the Bonds of any series or any tranche or tranches of any series
entitled to vote then outstanding and affected by such modification or
alteration, in case one or more but less than all of the series of Bonds or
of any tranche or tranches of any series of Bonds then outstanding under
the Indenture are so affected; provided, however, that no such modification
or alteration shall be made which will affect the terms of payment of the
principal of, or interest or premium, if any, on this Bond.

     In case an Event of Default, as defined in the Indenture, shall occur,
the principal of all the New Mortgage Bonds of the 6.99% Series at any such
time outstanding under the Indenture may be declared or may become due and
payable, upon the conditions and in the manner and with the effect provided
in the Indenture.  The Indenture provides that such declaration may be
rescinded under certain circumstances.

                           Article II
        Issue Of New Mortgage Bonds Of The 6.99% Series

     Section 1.  The Company hereby exercises the right to obtain the
authentication of $25,000,000 principal amount of Bonds pursuant to the
terms of Section 4.03 of the Indenture.  All such Bonds shall be New
Mortgage Bonds of the 6.99% Series.

     Section 2.  Such New Mortgage Bonds of the 6.99% Series may be
authenticated and delivered prior to the filing for recordation of this
Supplemental Indenture.

                          Article III
                           Redemption

     Section 1.  The New Mortgage Bonds of the 6.99% Series shall, upon the
notice and in the manner and with the effect provided in Article Five of
the Original Indenture, as amended by Section 3 of this Article III, be
redeemable (otherwise than out of moneys specified in Section 2 of this
Article III), at any time, on or after September 1, 1997 and prior to
maturity, at the option of the Company, as a whole, upon payment of the
principal amount of each of the New Mortgage Bonds of the 6.99% Series to
be redeemed, and accrued interest thereon to the redemption date, together
with the applicable Make-Whole Amount (as hereinafter defined).

     On or before the redemption date specified in the notice of redemption
given by the Company as provided in the Indenture, the Company shall
deliver to each holder of the New Mortgage Bonds of the 6.99% Series to be
redeemed, a certificate signed by a principal financial officer of the
Company setting forth the Make-Whole Amount (determined in good faith by
the Company as of the date five business days prior to the date of such
redemption), if any, applicable to the New Mortgage Bonds of the 6.99%
Series held by such holder so to be redeemed.  In the event the Company
shall incorrectly compute the Make-Whole Amount payable in connection with
any New Mortgage Bond of the 6.99% Series, the holder of such Bond shall
not be bound by such incorrect computation, but shall instead be entitled
to receive an amount equal to the correct Make-Whole Amount, if any,
computed in compliance with the terms hereof.

     As used in this Section 1:

     "Make-Whole Amount" shall mean the excess, if any, of (i) the
aggregate present value as of the date of such redemption of each dollar of
principal being prepaid and the amount of interest (exclusive of interest
accrued to the date of redemption) that would have been payable in respect
of such dollar if such redemption had not been made, determined by
discounting such amounts at the Reinvestment Rate from the respective dates
on which they would have been payable, over (ii) 100% of the principal
amount of the outstanding New Mortgage Bonds of the 6.99% Series being
redeemed.  If the Reinvestment Rate is equal to or higher than 6.99%, the
Make-Whole Amount shall be zero.  For purposes of any determination of the
Make-Whole Amount:

          "Reinvestment Rate" shall mean the arithmetic mean of the yields
     under the respective headings "This Week" and "Last Week" published in
     the Statistical Release under the caption "Treasury Constant
     Maturities" for the maturity (rounded to the nearest month)
     corresponding to the Weighted Average Life to Maturity of the
     principal amount of the New Mortgage Bonds of the 6.99% Series being
     redeemed.  If no maturity exactly corresponds to such Weighted Average
     Life to Maturity, yields for the two published maturities most closely
     corresponding to such Weighted Average Life to Maturity shall be
     calculated pursuant to the immediately preceding sentence and the
     Reinvestment Rate shall be interpolated or extrapolated from such
     yields on a straightline basis, rounding in each of such relevant
     periods to the nearest month.  For the purposes of calculating the
     Reinvestment Rate, the most recent Statistical Release published prior
     to the date of determination of the Make-Whole Amount shall be used.

          "Statistical Release" shall mean the then most recently published
     statistical release designated "H.15(519)" or any successor
     publication which is published weekly by the Federal Reserve System
     and which establishes yields on actively traded U.S. Government
     Securities adjusted to constant maturities or, if such statistical
     release is not published at the time of any determination hereunder,
     then such other reasonably    comparable index which shall be
     designated by the holders of 66-2/3% in aggregate principal amount of
     the outstanding New Mortgage Bonds of the 6.99% Series.

          "Weighted Average Life to Maturity" of any of the New Mortgage
     Bonds of the 6.99% Series to be redeemed shall mean the number of
     years (rounded to the nearest one-twelfth of a year) obtained by
     dividing the then Remaining Dollar-Years of the New Mortgage Bonds of
     the 6.99% Series by the then outstanding principal amount of such
     Bonds.  For the purposes of this definition, "Remaining Dollar-Years"
     means the sum of the amounts obtained by multiplying the amount of
     each then remaining sinking fund or other required repayment,
     including repayment at final maturity, by the number of years
     (calculated to the nearest one-twelfth of a year) which will elapse
     between the time of such determination and the date of such repayment.

     Section 2.  Upon the notice and in the manner and with the effect
provided in Article Five of the Original Indenture, as amended by Section 3
of this Article III, any of the New Mortgage Bonds of the 6.99% Series
shall be redeemable on the first day of September in each year, commencing
in 1998, by operation of the sinking fund provided for by Section 1 of
Article IV hereof, upon payment of the principal amount thereof together
with accrued interest to the redemption date.

     Section 3.  Whenever the Company shall propose to redeem less than all
of the outstanding New Mortgage Bonds of the 6.99% Series on any redemption
date, the Trustee, instead of selecting by lot, shall select the serial
numbers of the New Mortgage Bonds of the 6.99% Series to be redeemed (in
whole or in part) by prorating, as nearly as may be, the aggregate
principal amount of the New Mortgage Bonds of the 6.99% Series to be
redeemed among the registered owners of the New Mortgage Bonds of the 6.99%
Series according to the principal amount thereof registered in their
respective names.  In any such proration, the Trustee shall make such
adjustments, reallocations and eliminations as it shall deem proper to the
end that the principal amount of the New Mortgage Bonds of the 6.99% Series
so prorated to any registered owner of the New Mortgage Bonds of the 6.99%
Series shall be $1,000 or a multiple thereof, by increasing or decreasing
or eliminating the amount which would be allocable to any such registered
owner on the basis of exact proportion by an amount not exceeding $1,000.
The Trustee in its discretion may determine the particular New Mortgage
Bonds of the 6.99% Series (if there are more than one) registered in the
name of any registered owner which are to be redeemed, in whole or in part.
In any determination by proration pursuant to this Section, New Mortgage
Bonds of the 6.99% Series held by the Company shall not be considered
outstanding and shall be excluded in making the determination of the New
Mortgage Bonds of the 6.99% Series to be redeemed.

     Notice of redemption of any New Mortgage Bonds of the 6.99% Series
shall be given as provided in Section 5.04 of the Original Indenture,
except that, in the case of redemption by operation of the sinking fund for
such bonds, the notice shall state that the redemption is for the account
of the sinking fund.  If given by mail, the mailing of such notice shall be
a condition precedent to redemption, provided that any notice which is
mailed in the manner provided in Section 5.04 of the Original Indenture
shall be conclusively presumed to have been duly given whether or not the
holders receive such notice, and failure to give such notice by mall, or
any defect in such notice, to the holder of any such bond designated for
redemption in whole or in part shall not affect the validity of the
redemption of any other such bond.

     Except for the determination of the serial numbers of the New Mortgage
Bonds of the 6.99% Series to be redeemed (in whole or in part) by proration
as provided in this Section when less than all of the New Mortgage Bonds of
the 6.99% Series are to be redeemed on any redemption date and except for
the changes in the giving of notice of redemption as provided in this
Section, the procedures for redemption of the New Mortgage Bonds of the
6.99% Series shall be as provided in Article Five of the Original
Indenture.

     Section 4.  The Company, with the approval of the Trustee, may enter
into a written agreement with the holder of any New Mortgage Bonds of the
6.99% Series providing that payment of such bonds called for redemption in
part only be made directly by mail, wire transfer or in any other manner to
the holder thereof without presentation or surrender thereof if there shall
be delivered to the Trustee an agreement (which may be a composite with
other such agreements) between the Company and such holder (or other person
acting as agent for such holder or for whom such holder is a nominee) that
payment shall be so made, and that in the event the holder thereof shall
sell or transfer any such bonds (a) it will, prior to the delivery of such
bonds, either (i) surrender such bonds to the Trustee to make a proper
notation of the amount of principal paid thereon or (ii) surrender such
bonds to the Trustee against receipt of one or more New Mortgage Bonds of
the 6.99% Series in an aggregate principal amount equal to the unpaid
principal portion of the bonds so surrendered, and (b) it will promptly
notify the Company of the name and address of the transferee of any New
Mortgage Bonds of the 6.99% Series so transferred.  The Trustee shall not
be liable or responsible to any such holder or transferee or to the Company
or to any other person for any act or omission to act on the part of the
Company or any such holder in connection with any such agreement.  The
Company will indemnify and save the Trustee harmless against any liability
resulting from any such act or omission and against any liability resulting
from any action taken by the Trustee in accordance with the provisions of
any such agreement.

                           Article IV
                      Additional Covenants

     The Company covenants and agrees, subject to the terms and of this
Section, that it will pay to the Trustee on or before the last day of
August, 1998 and on or before the last day of August in each calendar year
thereafter so long as any New Mortgage Bonds of the 6.99% Series shall be
outstanding (each such last day of August being referred to herein as a
"sinking fund payment date") as and for a cash sinking fund for the
retirement of New Mortgage Bonds of the 6.99% Series, a sum in cash
sufficient to redeem on the first day of September next following such
sinking fund payment date, at the redemption price for the redemption of
New Mortgage Bonds of the 6.99% Series by operation of the sinking fund, a
principal amount of bonds of said series at least equal to twenty per
centum of the greatest principal amount of bonds of said series outstanding
at any time (determined as in this Section provided) between September 1,
1992, and the end of the calendar year immediately preceding such sinking
fund payment date.  Cash paid to the Trustee by the Company pursuant to
this Section shall be applied by the Trustee to the redemption on the next
following the first day of September of the specified principal amount of
New Mortgage Bonds of the 6.99% Series in accordance with provisions of
this Section; and the Company shall carry out the procedures required of it
for such redemption.

     On or before the first day of July in each year beginning with the
calendar year 1998, so long as any New Mortgage Bonds of the 6.99% Series
shall be outstanding, the Company shall deliver to the Trustee a
certificate, signed in the name of the Company by its President or one of
its Vice Presidents and by its Treasurer or an Assistant Treasurer,
containing the statements required by Section 1.05 of the Original
Indenture, and showing the greatest principal amount of New Mortgage Bonds
of the 6.99% Series outstanding at any time between September 1, 1992 and
the end of the preceding calendar year, determined in accordance with the
provisions of this Section, which certificate shall include, or be
accompanied by, the notice from the Company to the Trustee pursuant to
Section 5.04 of the Original Indenture, as amended by Section 3 of Article
III hereof, specifying the principal amount of the New Mortgage Bonds of
the 6.99% Series to be redeemed on the first day of September next
following by operation of the sinking fund provided for by this Section.

     In determining under the provisions of this Section the principal
amount of New Mortgage Bonds of the 6.99% Series outstanding under the
Indenture, there shall be excluded the principal amount of any bonds of
said series authenticated under the Indenture which are owned by the
Company.

     Any and all New Mortgage Bonds of the 6.99% Series received by the
Trustee pursuant to any provision of this Section shall thereupon be
canceled and destroyed by the Trustee.

     If the first day of September in the calendar year 1998, or in any
calendar year thereafter so long as any New Mortgage Bonds of the 6.99%
Series shall be outstanding, is a legal holiday or day on which banking
institutions which act as paying agents hereunder are authorized by law to
close, then payment of the redemption price (including interest payable
upon redemption) for purposes of redemption of New Mortgage Bonds of the
6.99% Series by operation of the sinking fund provided for by this Section
may be made on the next succeeding day which is not a legal holiday or a
day on which such banking institutions are authorized by law to close with
the same force and effect as if made on the nominal redemption date, and no
interest shall accrue for the period after the nominal redemption date.

                           Article V
                          The Trustee
