Section 3801 ET SEQ.) (the "Delaware Act") and Northwestern Public Service
Company, a Delaware corporation, as holder of the Common Securities (as defined
herein) of the Trust and as guarantor (the "Company"), propose that the Trust
issue and sell [   ] aggregate number of its [  ]% Trust Preferred Capital
Securities (liquidation amount $25 per security), representing preferred

in, the Preferred Securities Guarantee Agreement (the "Preferred Securities
Guarantee Agreement"), dated as of _________ __, 1995, between the Company and
Wilmington Trust Company, as Trustee (the "Guarantee Trustee").  The Preferred
Securities and the related Preferred Securities Guarantee are referred to herein

          The entire proceeds from the sale of the Securities will be combined

securities representing common undivided beneficial interests in the assets of
the Trust (the  "Common Securities") guaranteed by the Company, to the extent
set



forth in the Prospectus, with respect to distributions and payments upon
liquidation, redemption and otherwise (the "Common Securities Guarantee" and
together with the Preferred Securities Guarantee, the "Guarantees") pursuant to
the Common Securities Guarantee Agreement (the "Common Securities Guarantee
Agreement" and, together with the Preferred Securities Guarantee Agreement, the
"Guarantee Agreements"), dated as of _______ __, 1995, between the Company and
the Guarantee Trustee, as Trustee, and will be used by the Trust to purchase
subordinated debt securities issued by the Company ("Subordinated Debt
Securities" and, together with the Guarantee Agreements and the Guarantees, the

be issued pursuant to the amended and restated declaration of trust of the
Trust, dated as of _______ __, 1995 (the "Declaration"), among the Company, as
Sponsor, the trustees named therein (the "Trustees") and the holders from time

Manhattan Bank (N.A.), as trustee (the "Debt Trustee"), and a supplement to the

All obligations of the Underwriters are several and not joint.  The use of the

          (u)  On the basis of the present knowledge of the senior management of
the Company as to the business and affairs of Synergy Group Incorporated, a
Delaware corporation ("Synergy"), and its subsidiaries, the Company has no
reason to believe that the representations contained in subsections (r) and (t)

in the Prospectus (the "Acquisition").

          (v)  The unaudited pro forma consolidated financial statements
included or incorporated by reference in the Registration Statement and the
Prospectus have been prepared in good faith by the Company, and the assumptions
on which such pro forma financial statements have been prepared provide a
reasonable basis for presenting the significant effects directly attributable to
the Acquisition described in the notes thereto.

          (w)  The Company is not aware of any facts or circumstances that would
prevent any of the conditions to the consummation of the Acquisition contained
in the Purchase and Sale Agreement dated as of May 17, 1995, by and among
Synergy and the other parties thereto (the "Acquisition Agreement") from being
satisfied in the ordinary course on or prior to September 30, 1995.

          2.   PUBLIC OFFERING.  The Trust and the Company are advised by the
Representative that the Underwriters propose to make a public offering of their
respective portions of the Preferred Securities as soon after this Agreement has
been entered into as in the judgment of the Representative is advisable.  The
terms of the public offering of the Preferred Securities are set forth in the
Prospectus.

          3.   PURCHASE AND DELIVERY.  Subject to the terms and conditions set
forth or incorporated by reference herein, the Trust hereby agrees to sell, and
the Underwriters agree to purchase, severally and not jointly, the respective
number of Preferred Securities set forth below opposite their names in Schedule
I hereto at a purchase price of $[   ] per Preferred Security.


                                       -8-


          The Company agrees to issue the Company Securities concurrently with
the issue and sale of the Preferred Securities as contemplated herein.     The
Company hereby guarantees the timely performance by the Trust of its obligations
under this Section 3.  The Trust agrees to purchase the Subordinated Debt
Securities with the proceeds of, and concurrently with, the issue and sale of
the Securities.

           As compensation to the Underwriters for their commitments hereunder,
and because the proceeds of the sale of the Preferred Securities will be loaned
by the Trust to the Company, the Company hereby agrees to pay on the Closing
Date to the Representative, for the accounts of the several Underwriters, an
amount equal to (i) in the case of such number of Preferred Securities as are
reserved by the Underwriters for sale to institutional investors, $ ____ per
Preferred Security and (ii) in the case of such number of Preferred Securities
as are not so reserved, $ _____ per Preferred Security.  The Underwriters shall
inform the Company in writing, not later than the business day prior to the
Closing Date, of the number of Preferred Securities reserved for sale to such
institutional investors.

          Payment for the Preferred Securities shall be made by certified or
official bank check or checks payable, or by wire transfer, to the order of the
Trust in immediately available funds at the office of Winthrop, Stimson, Putnam
& Roberts, New York, New York, at 10:00 A.M. local time, on _____, 1995, or at
such other time on the same or such other date, not later than _______, 199_, as
shall be designated in writing by the Representative.  The time and date of such
payment are hereinafter referred to as the "Closing Date".

          Certificates for the Preferred Securities shall be in definitive form
and registered in such names and in such denominations as the Underwriters shall
request not later than two full business days prior to the Closing Date or the
Option Closing Date, as the case may be.  The certificates evidencing the
Preferred Securities shall be delivered to the Representative, through the
facilities of the Depository Trust Company ("DTC") for the account of the
Representative with any transfer taxes payable in connection with the transfer
of the Securities duly paid, against payment of the purchase price therefor.

          4.   CONDITIONS TO CLOSING.  The several obligations of the
Underwriters hereunder are subject to the following conditions:

          (a)  Subsequent to the execution and delivery of the Underwriting

     subsidiaries, taken as a whole, or the Trust, from that set forth in the
     Prospectus, that, in the judgment of the Representative, is material and
     adverse and that makes it, in the judgment of the Representative,
     impracticable to market the Preferred Securities on the terms and in the
     manner contemplated in the Prospectus; and

             (iii)  the Company shall have obtained an appropriate order or
     orders of the FERC authorizing the issuance, sale and delivery of the
     Company Securities as contemplated by this Agreement, which order or orders

material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The officer signing
and delivering such certificate may rely upon the best of his knowledge as to
proceedings threatened.

          (ii) The Underwriters shall have received on the Closing Date a
certificate, dated the Closing Date and signed by an authorized representative

that the representations and warranties of the Trust contained in the
Underwriting Agreement are true and correct as of the Closing Date and that the
Trust has complied with all of the agreements and satisfied all of the
conditions on its part to be performed or satisfied on or before the Closing
Date.  The representative signing and delivering such certificate may rely upon
the best of his knowledge as to proceedings threatened.

     in such business and is duly qualified and in good standing in each
     jurisdiction in which the conduct of its business or its ownership or
     leasing of property requires such qualification, except to the extent that

     material adverse effect on the Company and its subsidiaries, taken as a

against all loss, liability, claim, damage and expense whatsoever, as due from
the Trust under Section 6(a) hereof.

          (c)  Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the directors, officers or Trustees of the Company or the
Trust who sign the Registration Statement and each person, if any, who controls
the Company or the Trust within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company and the Trust to such Underwriter, but only
with reference to information relating to such Underwriter furnished to the
Company and Trust in writing by such Underwriter expressly for use in the
Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

          (d)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to either paragraph (a) or (b) above, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by the Representative, in the case of parties indemnified
pursuant to paragraph (a) above, and by the Company, in the case of parties
indemnified pursuant to paragraph (b) above.  The


                                      -22-


indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment.  Notwithstanding the foregoing sentence, if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second and third sentences of this paragraph, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement.  No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

          (e)  To the extent the indemnification provided for in paragraph (a)
or (b) of this Section 6 is unavailable to an indemnified party or insufficient
in respect of any losses, claims, damages or liabilities referred to therein,
then each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Trust on the one hand and the
Underwriters on the other hand from the offering of the Preferred Securities or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company or the Trust on the one hand and of the Underwriters on the other
hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Company and the Trust on
the one hand and the Underwriters on the other hand in connection with the
offering of the Preferred Securities shall be deemed to be in the same
respective proportions as the net proceeds from the offering of such Securities
(before deducting expenses) received by the Company and the Trust and the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover of the Prospectus Supplement, bear
to the aggregate public offering price of the Preferred Securities.  The
relative fault of the Company and the Trust on


                                      -23-


the one hand and of the Underwriters on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Trust or by
the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Underwriters' respective obligations to contribute pursuant to this
Section 6 are several in proportion to the respective principal amounts of
Preferred Securities they have purchased hereunder, and not joint.

          (f)  The Company, the Trust and the Underwriters agree that it would
not be just or equitable if contribution pursuant to this Section 6 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above.  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Preferred Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The remedies provided for in this
Section 6 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.

          7.   TERMINATION.  This Agreement shall be subject to termination, by
notice given by the Representative to the Company and the Trust, if (a) after
the execution and delivery of the Underwriting Agreement and prior to the
Closing Date (i) trading generally shall have been suspended or materially
limited on or by, as the case may be, any of the New York Stock Exchange, the
American Stock Exchange, the National Association of Securities Dealers, Inc.,
the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the
Chicago Board of Trade, (ii) trading of any securities of the Trust or the
Company shall have been suspended on any exchange or in any over-the-counter
market, (iii) a general moratorium on commercial banking activities in New York
shall have been declared by either Federal or New York State authorities or (iv)
there shall have occurred any outbreak or escalation of hostilities or any
change in financial markets


                                      -24-


or any calamity or crisis that, in the judgment of the Representative, is
material and adverse and (b) in the case of any of the events specified in
clauses (a)(i) through (iv), such event, singly or together with any other such
event, makes it, in the judgment of the Representative, impracticable to market
the Preferred Securities on the terms and in the manner contemplated in the
Prospectus.  This Agreement may also be terminated at any time prior to the
Closing Date if in the judgment of the Representative the subject matter of any
amendment or supplement to the Registration Statement or Prospectus prepared and
furnished by the Company and its subsidiaries, taken as a whole, or the Trustee
reflects a material adverse change in the business, properties or financial
condition of the Company or the Trust which renders it either inadvisable to
proceed with such offering, if any, or inadvisable to proceed with the delivery
of the Preferred Securities to be purchased hereunder.

          8.   DEFAULTING UNDERWRITERS.  If, on the Closing Date or the Option
Closing Date, as the case may be, any one or more of the Underwriters shall fail
or refuse to purchase the Preferred Securities that it has or they have agreed
to purchase hereunder on such date, and the aggregate amount of Preferred
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase is not more than one-tenth of the aggregate amount of the
Preferred Securities to be purchased on such date, the other Underwriters shall
be obligated severally in the proportions that the amount of Preferred
Securities set forth opposite their respective names in the Underwriting
Agreement bears to the aggregate amount of Preferred Securities set forth
opposite the names of all such non-defaulting Underwriters, or in such other
proportions as the Representative may specify, to purchase the Preferred
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; PROVIDED that in no event shall the amount
of Preferred Securities that any Underwriter has agreed to purchase pursuant to
this Agreement be increased pursuant to this Section 8 by an amount in excess of
one-ninth of such amount of Preferred Securities without the written consent of
such Underwriter.  If, on the Closing Date or the Option Closing Date, as the
case may be, any Underwriter or Underwriters shall fail or refuse to purchase
Securities that it has or they have agreed to purchase and the aggregate amount
of Preferred Securities with respect to which such default occurs is more than
one-tenth of the aggregate amount of Preferred Securities to be purchased on
such date, and arrangements satisfactory to the Representative and the Company
for the purchase of such Preferred Securities are not made within 36 hours after
such default, the Underwriting Agreement shall terminate without liability on
the part of any non-defaulting Underwriter, the Company or the Trust.  In any
such case either the Representative or the Company shall have the right to
postpone the Closing Date or the Option Closing Date, as the case may be, but in
no event for longer than seven days, in order that the required changes, if any,
in the Registration Statement and


                                      -25-


in the Prospectus or in any other documents or arrangements may be effected.
Any action taken under this paragraph shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
the Underwriting Agreement.

          If the Underwriting Agreement shall be terminated by the Underwriters,
or any of them, because of any failure or refusal on the part of the Company or
the Trust to comply with the terms or to fulfill any of the conditions of the
Underwriting Agreement, or if for any reason the Company or the Trust shall be
unable to perform its obligations under the Underwriting Agreement, the Company
and the Trust will reimburse the Underwriters or such Underwriters as have so
terminated the Underwriting Agreement with respect to themselves, severally, for
all out-of-pocket expenses (including the fees and disbursements of their
counsel) reasonably incurred by such Underwriters in connection with the
Underwriting Agreement or the offering of the Preferred Securities.

          If the Underwriting Agreement shall be terminated by the Company
because of any failure or refusal on the part of the Underwriters to comply with
the terms or to fulfill any of the conditions of the Underwriting Agreement, or
if for any reason the Underwriters shall be unable to perform their obligations
under the Underwriting Agreement, the Underwriters will reimburse the Company
for all out-of-pocket expenses (including the fees and disbursements of its
counsel) reasonably incurred by the Company in connection with the Underwriting
Agreement or the offering of the Preferred Securities.

          9.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE.  The respective
indemnity and contribution agreements and the representations, warranties and
other statements of the officers or Trustees of the Company and the Trust (as
the case may be) and the Underwriters set forth in the Underwriting Agreement
will remain in full force and effect, regardless of any termination of the
Underwriting Agreement, any investigation made by or on behalf of any
Underwriter, the Company or the Trust or any of the officers, directors or
controlling persons referred to in Section 6 and delivery of and payment for the
Preferred Securities.

          10.  SUCCESSORS.  This Agreement will enure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers, directors and controlling persons referred to in Section 6, and no
other person will have any right or obligation hereunder.

          11.  COUNTERPARTS.  The Underwriting Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.


                                      -26-


          12.  APPLICABLE LAW.  The Underwriting Agreement shall be governed by
and construed in accordance with the internal laws of the State of New York.

          13.  HEADINGS.  The headings of the sections of the Underwriting
Agreement have been inserted for convenience of reference only and shall not be
deemed a part of the Underwriting Agreement.

          14.  NOTICES.  All communications hereunder will be in writing and, if
sent to (i) the Underwriters, will be mailed, delivered or telecopied and
confirmed to Morgan Stanley & Co. Incorporated at 1251 Avenue of the Americas,

this Agreement, shall be deemed to refer only to (i) those direct or indirect
subsidiaries of the Company which would qualify as "significant subsidiaries"
pursuant to Rule 405 under the Securities Act, and (ii) SYN Inc.

          16.  CERTAIN AGREEMENTS AND REPRESENTATIONS OF NATWEST CAPITAL MARKETS
LIMITED.  NatWest Capital Markets Limited agrees and represents that (i) it has
not offered or sold and will not offer or sell any Preferred Securities to
