          Ladies and Gentlemen:

               MDU Resources Group, Inc., a Delaware corporation (the
          "Company"), and the persons listed in Schedule B hereto (the
          "Selling Shareholders"), confirm their respective agreements with
          Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
          Incorporated ("Merrill Lynch") and each of the other Underwriters
          named in Schedule A hereto (collectively, the "Underwriters",
          which term shall also include any underwriter substituted as
          hereinafter provided in Section 10 hereof), for whom Merrill
          Lynch, Donaldson, Lufkin & Jenrette Securities Corporation,
          Edward D. Jones & Co., L.P. and Lehman Brothers, Inc. are acting
          as representatives (in such capacity, the "Representatives"),
          with respect to (i) the sale by the Company and the Selling
          Shareholders, acting severally and not jointly, and the purchase
          by the Underwriters, acting severally and not jointly, of the
          respective numbers of shares of Common Stock, par value $3.33 per
          share, of the Company ("Common Stock") and the appurtenant
          preference share purchase rights (the "Rights", and together with
          the Common Stock, the "Initial Securities") set forth in
          Schedules A and B hereto and (ii) the grant by the Company to the
          Underwriters, acting severally and not jointly, of the option
          described in Section 2(b) hereof to purchase all or any part of
          300,000 additional shares of Common Stock and the rights attached
          thereto to cover over-allotments, if any (the "Option
          Securities").  The outstanding Rights have been issued pursuant
          to a Rights Agreement (the "Rights Agreement") dated as of
          November 3, 1988 between the Company and Norwest Bank Minnesota,
          N.A., as Rights Agent.  The Initial Securities and the Option
          Securities are hereinafter called, collectively, the
          "Securities."

               The Company and the Selling Shareholders understand that the
          Underwriters propose to make a public offering of the Securities
          as soon as the Representatives deem advisable after this
          Agreement has been executed and delivered.

               The Company has filed with the Securities and Exchange
          Commission (the "Commission") a registration statement on Form S-
          3 (No. 333-48647) for the registration of the Securities under
          the Securities Act of 1933, as amended (the "1933 Act") and the
          offering thereof from time to time in accordance with Rule 415 of
          the rules and regulations of the Commission under the 1933 Act
          (the "1933 Act Regulations"), and the Company has filed such
          post-effective amendments thereto as may be required prior to the
          execution of this Agreement.  Such registration statement (as so
          amended, if applicable) has been declared effective by the
          Commission.  Such registration statement (as so amended, if
          applicable) is referred to herein as the "Registration
          Statement", and the final prospectus and the final prospectus
          supplement relating to the offering of the Securities, in the
          form first furnished to the Underwriters by the Company for use
          in connection with the offering of the Securities, are
          collectively referred to herein as the "Prospectus", provided,
          however, that all references to the "Registration Statement" and
          the "Prospectus" shall also be deemed to include all documents
          incorporated therein by reference pursuant to the Securities
          Exchange Act of 1934, as amended (the "1934 Act"), prior to the
          execution of this Agreement.  A "preliminary prospectus" shall be
          deemed to refer to any prospectus used before the registration
          statement became effective and any prospectus that omitted
          information to be included upon pricing in a form of prospectus
          filed with the Commission pursuant to Rule 424 of the 1933 Act
          Regulations, that was used after such effectiveness and prior to
          the execution and delivery of this Agreement.  For purposes of
          this Agreement, all references to the Registration Statement,
          Prospectus, or preliminary prospectus or to any amendment or
          supplement to any of the foregoing shall be deemed to include any
          copy filed with the Commission pursuant to its Electronic Data
          Gathering, Analysis and Retrieval system ("EDGAR").

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

               SECTION 1.     Representations and Warranties.
                              ------------------------------

               (a)  Representations and Warranties by the Company.  The
          Company represents and warrants to each Underwriter, and agrees
          with each Underwriter, as follows:

                    (i) Compliance with Registration Requirements.  The 
                        -----------------------------------------
               Company meets the requirements for use of Form S-3 under the
               1933 Act.  The Registration Statement has become effective
               under the 1933 Act and no stop order suspending the
               effectiveness of the Registration Statement has been issued
               under the 1933 Act and no proceedings for that purpose have
               been instituted or are pending or, to the knowledge of the
               Company, are contemplated by the Commission, and any request
               on the part of the Commission for additional information has
               been complied with.

                    At the respective times the Registration Statement and
               any post-effective amendments thereto became effective and
               at the Closing Time (and, if any Option Securities are
               purchased, at the Date of Delivery), the Registration
               Statement and any amendments and supplements thereto
               complied and will comply in all material respects with the
               requirements of the 1933 Act and the 1933 Act Regulations
               and did not and will not contain an untrue statement of a
               material fact or omit to state a material fact required to
               be stated therein or necessary to make the statements
               therein not misleading.  Neither the Prospectus nor any
               amendments or supplements thereto, at the time the
               Prospectus or any such amendment or supplement was first
               furnished to the Underwriters and at the Closing Time (and,
               if any Option Securities are purchased, at the Date of
               Delivery), included or will include an untrue statement of a
               material fact or omitted or will omit to state a material
               fact necessary in order to make the statements therein, in
               the light of the circumstances under which they were made,
               not misleading.  The representations and warranties in this
               subsection shall not apply to statements in or omissions
               from the Registration Statement or Prospectus made in
               reliance upon and in conformity with information furnished
               to the Company in writing by any Underwriter through Merrill
               Lynch expressly for use in the Registration Statement or
               Prospectus.

                    Each preliminary prospectus and the prospectus filed as
               part of the Registration Statement as originally filed or as
               part of any amendment thereto, or filed pursuant to Rule 424
               under the 1933 Act, complied when so filed in all material
               respects with the 1933 Act Regulations and each preliminary
               prospectus and the Prospectus delivered to the Underwriters
               for use in connection with this offering was identical to
               the electronically transmitted copies thereof filed with the
               Commission pursuant to EDGAR, except to the extent permitted
               by Regulation S-T.

                    (ii)  Incorporated Documents.  The documents 
                          ----------------------
               incorporated or deemed to be incorporated by reference in
               the Registration Statement and the Prospectus, at the time
               they were or hereafter are filed with the Commission,
               complied and will comply in all material respects with the
               requirements of the 1934 Act and the rules and regulations
               of the Commission thereunder (the "1934 Act Regulations"),
               and, when read together with the other information in the
               Prospectus, at the time the Registration Statement became
               effective, at the time the Prospectus was first furnished to
               the Underwriters and at the Closing Time (and, if any Option
               Securities are purchased, at the Date of Delivery), did not
               and will not contain an untrue statement of a material fact
               or omit to state a material fact required to be stated
               therein or necessary to make the statements therein not
               misleading.

                    (iii)  Independent Accountants.  The accountants who 
                           -----------------------
               certified the financial statements and supporting schedules
               included in the Registration Statement are independent
               public accountants as required by the 1933 Act and the 1933
               Act Regulations.

                    (iv)  Financial Statements.  The financial statements 
                          --------------------
               included in the Registration Statement and the Prospectus,
               together with the related schedules (if any) and notes,
               present fairly the financial position of the Company and its
               consolidated subsidiaries at the dates indicated and the
               statement of operations, stockholders' equity and cash flows
               of the Company and its consolidated subsidiaries for the
               periods specified; said financial statements have been
               prepared in conformity with generally accepted accounting
               principles ("GAAP") applied on a consistent basis throughout
               the periods involved (except as disclosed therein).  The
               supporting schedules, if any, included in the Registration
               Statement present fairly in accordance with GAAP the
               information required to be stated therein.  The selected
               financial data and the summary financial information
               included in the Prospectus present fairly the information
               shown therein and have been compiled on a basis consistent
               with that of the audited financial statements included in
               the Registration Statement.

                    (v)  No Material Adverse Change in Business.  Since the
                         --------------------------------------
               respective dates as of which information is given in the
               Registration Statement and the Prospectus, except as
               otherwise stated therein, (A) there has been no material
               adverse change in the condition, financial or otherwise, or
               in the results of operations, business affairs or properties
               of the Company and its subsidiaries considered as one
               enterprise, whether or not arising in the ordinary course of
               business or any development which the Company has reason to
               believe would result in a prospective material adverse
               change (a "Material Adverse Effect"), (B) there have been no
               transactions entered into by the Company or any of its
               subsidiaries, other than those in the ordinary course of
               business, which are material with respect to the Company and
               its subsidiaries considered as one enterprise, and
               (C) except for regular quarterly dividends on the Common
               Stock or Preferred Stock in amounts per share that are
               consistent with past practice, there has been no dividend or
               distribution of any kind declared, paid or made by the
               Company on any class of its capital stock.

                    (vi)  Good Standing of the Company.  The Company has 
                          ----------------------------
               been duly organized and is validly existing as a corporation
               in good standing under the laws of the State of Delaware and
               has corporate power and authority to own, lease and operate
               its properties and to conduct its business as described in
               the Prospectus and to enter into and perform its obligations
               under this Agreement; and the Company is duly qualified as a
               foreign corporation to transact business and is in good
               standing in each other jurisdiction in which such
               qualification is required, whether by reason of the
               ownership or leasing of property or the conduct of business,
               except where the failure so to qualify or to be in good
               standing would not result in a Material Adverse Effect;

                    (vii)  Good Standing of Subsidiaries.  Each of

               domestic or foreign, having jurisdiction over such Selling
               Shareholder or any of its properties (except that no
               representation is made with respect to state securities
               laws).

                    (iii)  Good and Marketable Title.  Such Selling 
                           -------------------------

               the purchase price therefor as herein contemplated, assuming
               each such Underwriter has no notice of any adverse claim,
               each of the Underwriters will receive good and marketable
               title to the Securities purchased by it from such Selling
               Shareholder, free and clear of any security interest,
               mortgage, pledge, lien, charge, claim, equity or encumbrance

               therefor; and the Attorney-in-Fact is authorized to execute

               to be sold by such Selling Shareholder hereunder, to
               determine the purchase price to be paid by the Underwriters

               Selling Shareholder in connection with this Agreement.

                    (v)  Absence of Manipulation.  Such Selling Shareholder
                         -----------------------
               has not taken, and will not take, directly or indirectly,
               any action which is designed to or which has constituted or
               which might reasonably be expected to cause or result in
               stabilization or manipulation of the price of any security
               of the Company to facilitate the sale or resale of the
               Securities.

                    (vi)  Absence of Further Requirements.  No filing with,

               or consent, approval, authorization, order, registration,
               qualification or decree of, any court or governmental

               delivery of the Securities hereunder or the consummation of
               the transactions contemplated by this Agreement, except such
               as may have previously been made or obtained or as may be
               required under the 1933 Act or the 1933 Act Regulations or
               state securities laws.

                    (vii)  Restriction on Sale of Securities.  During a 
                           ---------------------------------
               period of 90 days from the date of the Prospectus, such

               directly or indirectly, any share of Common Stock or any
               securities convertible into or exercisable or exchangeable
               for Common Stock or file any registration statement under
               the 1933 Act with respect to any of the foregoing except
               that the Selling Shareholder may make the following
               transfers: (A) any bona fide gift of shares by such Selling
               Shareholder, including a charitable gift, (B) any transfer
               of such shares by a Selling Shareholder to a trustee for the
               benefit of such Selling Shareholder or such Selling
               Shareholder's ancestors, descendants or spouse, and (C) any
               transfer of such shares by such Selling Shareholder to such

               representatives, heirs or devisees pursuant to the laws of
               descent and distribution, provided that in any such case,
               such shares may not be resold in a public offering until the
               expiration of the foregoing period; or (ii) enter into any
               swap or any other agreement or any transaction that
               transfers, in whole or in part, directly or indirectly, the
               economic consequence of ownership of the Common Stock,
               whether any such swap or transaction described in clause (i)
               or (ii) above is to be settled by delivery of Common Stock
               or such other securities, in cash or otherwise.  The
               foregoing sentence shall not apply to the Securities to be
               sold hereunder.

                    (viii)  Certificates Suitable for Transfer.

               Certificates for all of the Securities to be sold by such
               Selling Shareholder pursuant to this Agreement, in suitable
               form for transfer by delivery or accompanied by duly
               executed instruments of transfer or assignment in blank with

               Agreement.

                    (ix)  No Association with NASD.  Neither such Selling 
                          ------------------------
               Stockholder nor any of his/her affiliates directly, or
               indirectly through one or more intermediaries, controls, or
               is controlled by, or is under common control with, or has
               any other association with (within the meaning of Article I,

          officer of the Company or any of its subsidiaries delivered to
          the Representatives or to counsel for the Underwriters shall be
          deemed a representation and warranty by the Company to each
          Underwriter as to the matters covered thereby; and any
          certificate signed by or on behalf of the Selling Shareholders as
          such and delivered to the Representatives or to counsel for the
          Underwriters pursuant to the terms of this Agreement shall be
          deemed a representation and warranty by such Selling Shareholder
          as to the matters covered thereby.

               SECTION 2.     Sale and Delivery to Underwriters; Closing.
                              ------------------------------------------

               (a)  Initial Securities.  On the basis of the respective
          representations and warranties herein contained and subject to
          the terms and conditions herein  set forth, the Company and each
          Selling Shareholder, severally and not jointly, agree to sell to
          each Underwriter, severally and not jointly, and each
          Underwriter, severally and not jointly, agrees to purchase from
          the Company and each Selling Shareholder, at the price per share
          set forth in Schedule C, that proportion of the number of Initial
          Securities set forth in Schedule B opposite the name of the
          Company or such Selling Shareholder, as the case may be, which
          the number of Initial Securities set forth in Schedule A opposite
          the name of such Underwriter, plus any additional number of
          Initial Securities which such Underwriter may become obligated to
          purchase pursuant to the provisions of Section 10 hereof, bears
          to the total number of Initial Securities, subject, in each case,
          to such adjustments among the Underwriters as the Representatives
          in their sole discretion shall make to eliminate any sales or
          purchases of fractional securities.

               (b)  Option Securities.  In addition, on the basis of the
          representations and warranties herein contained and subject to
          the terms and conditions herein set forth, the Company hereby
          grants an option to the Underwriters, severally and not jointly,
          to purchase up to an additional 300,000 shares of Common Stock
          and related Rights, as set forth in Schedule B, at the price per
          share set forth in Schedule C, less an amount per share equal to
          any dividends or distributions declared by the Company and
          payable on the Initial Securities but not payable on the Option
          Securities.  The option hereby granted will expire 30 days after
          the date hereof and may be exercised in whole or in part from
          time to time only for the purpose of covering over-allotments
          which may be made in connection with the offering and
          distribution of the Initial Securities upon notice by the
          Representatives to the Company setting forth the number of Option
          Securities as to which the several Underwriters are then
          exercising the option and the time and date of payment and
          delivery for such Option Securities.  Any such time and date of
          delivery (a "Date of Delivery") shall be determined by the
          Representatives, but shall not be later than seven full business
          days after the exercise of said option, nor in any event prior to
          the Closing Time, as hereinafter defined. If the option is
          exercised as to all or any portion of the Option Securities, each
          of the Underwriters, acting severally and not jointly, will
          purchase that proportion of the total number of Option Securities
          then being purchased which the number of Initial Securities set
          forth in Schedule A opposite the name of such Underwriter bears
          to the total number of Initial Securities, subject in each case
          to such adjustments as the Representatives in their discretion
          shall make to eliminate any sales or purchases of fractional
          shares.

               (c)  Payment.  Payment of the purchase price for, and
          delivery of certificates for, the Initial Securities shall be
          made at the offices of Reid & Priest LLP, 40 West 57th Street,
          New York, New York, or at such other place as shall be agreed
          upon by the Representatives and the Company and the Selling
          Shareholders, at 9:00 A.M. (Eastern time) on the third (fourth,
          if the pricing occurs after 4:30 P.M. (Eastern time) on any given
          day) business day after the date hereof (unless postponed in
          accordance with the provisions of Section 10), or such other time
          not later than ten business days after such date as shall be
          agreed upon by the Representatives and the Company and the
          Selling Shareholders (such time and date of payment and delivery
          being herein called "Closing Time").

               In addition, in the event that any or all of the Option
          Securities are purchased by the Underwriters, payment of the
          purchase price for, and delivery of certificates for, such Option
          Securities shall be made at the above-mentioned offices, or at
          such other place as shall be agreed upon by the Representatives
          and the Company, on each Date of Delivery as specified in the
          notice from the Representatives to the Company.

               Payment shall be made to the Company and the Selling
          Shareholders by wire transfer of immediately available funds to
          bank accounts designated by the Company and the Custodian
          pursuant to each Selling Shareholder's Custody Agreement and
          Power of Attorney, as the case may be, against delivery to the
          Representatives for the respective accounts of the Underwriters
          of certificates for the Securities to be purchased by them.  It
          is understood that each Underwriter has authorized the
          Representatives, for its account, to accept delivery of, receipt
          for, and make payment of the purchase price for, the Initial
          Securities and the Option Securities, if any, which it has agreed
          to purchase.  Merrill Lynch, individually and not as
          representative of the Underwriters, may (but shall not be
          obligated to) make payment of the purchase price for the Initial
          Securities or the Option Securities, if any, to be purchased by
          any Underwriter whose funds have not been received by the Closing
          Time or the relevant Date of Delivery, as the case may be, but
          such payment shall not relieve such Underwriter from its
          obligations hereunder.

               (d)  Denominations; Registration.  Certificates for the
          Initial Securities and the Option Securities, if any, shall be in
          such denominations and registered in such names as the
          Representatives may request in writing at least one full business
          day before the Closing Time or the relevant Date of Delivery, as
          the case may be.  The certificates for the Initial Securities and
          the Option Securities, if any, will be made available for
          examination and packaging by the Representatives in The City of
          New York not later than 10:00 A.M. (Eastern time) on the business
          day prior to the Closing Time or the relevant Date of Delivery,
          as the case may be.

               SECTION 3.     Covenants of the Company.  The Company 
                              ------------------------
          covenants with each Underwriter as follows:

               (a)  Compliance with Securities Regulations and Commission
          Requests.  The Company, subject to Section 3(b), will notify the
          Representatives immediately, and confirm the notice in writing,
          (i) when any post-effective amendment to the Registration
          Statement shall become effective, or any supplement to the
          Prospectus or any amended Prospectus shall have been filed,
          (ii) of the receipt of any comments from the Commission, (iii) of
          any request by the Commission for any amendment to the
          Registration Statement or any amendment or supplement to the
          Prospectus or for additional information, and (iv) of the
          issuance by the Commission of any stop order suspending the
          effectiveness of the Registration Statement or of any order
          preventing or suspending the use of any preliminary prospectus,
          or of the suspension of the qualification of the Securities for
          offering or sale in any jurisdiction, or of the initiation or
          threatening of any proceedings for any of such purposes.  The
          Company will promptly effect the filings necessary pursuant to
          Rule 424(b) and will take such steps as it deems necessary to
          ascertain promptly whether the form of prospectus transmitted for
          filing under Rule 424(b) was received for filing by the
          Commission and, in the event that it was not, it will promptly
          file such prospectus.  The Company will make every reasonable
          effort to prevent the issuance of any stop order and, if any stop
          order is issued, to obtain the lifting thereof at the earliest
          possible moment.

               (b)  Filing of Amendments.  The Company will give the
          Representatives notice of its intention to file or prepare any
          amendment to the Registration Statement (including any filing
          under Rule 462(b)), or any amendment, supplement or revision to
          either the prospectus included in the Registration Statement at
          the time it became effective or to the Prospectus, whether
          pursuant to the 1933 Act, the 1934 Act or otherwise, will (i) in
          all cases during the period when a prospectus is required to be
          delivered under the 1933 Act and (ii) thereafter, as to the
          Prospectus Supplement only, furnish the Representatives with
          copies of any such documents a reasonable amount of time prior to
          such proposed filing or use, as the case may be, and will not
          file or use any such document to which the Representatives or
          counsel for the Underwriters shall reasonably object.

               (c)  Delivery of Registration Statements.  The Company has
          furnished or will deliver to the Representatives and counsel for
          the Underwriters, without charge, signed copies of the
          Registration Statement as originally filed and of each amendment
          thereto (including exhibits filed therewith or incorporated by
          reference therein and documents incorporated or deemed to be
          incorporated by reference therein) and signed copies of all
          consents and certificates of experts, and will also deliver to
          the Representatives, without charge, a conformed copy of the
          Registration Statement as originally filed and of each amendment
          thereto (without exhibits) for each of the Underwriters.  The
          copies of the Registration Statement and each amendment thereto
          furnished to the Underwriters will be identical to the
          electronically transmitted copies thereof filed with the
          Commission pursuant to EDGAR, except to the extent permitted by
          Regulation S-T.

               (d)  Delivery of Prospectuses.  The Company has delivered to
          each Underwriter, without charge, as many copies of each
          preliminary prospectus as such Underwriter reasonably requested,
          and the Company hereby consents to the use of such copies for
          purposes permitted by the 1933 Act.  The Company will furnish to
          each Underwriter, without charge, during the period when the
          Prospectus is required to be delivered under the 1933 Act or the
          1934 Act, such number of copies of the Prospectus (as amended or
          supplemented) as such Underwriter may reasonably request.  The
          Prospectus and any amendments or supplements thereto furnished to
          the Underwriters will be identical to the electronically
          transmitted copies thereof filed with the Commission pursuant to
          EDGAR, except to the extent permitted by Regulation S-T.

               (e)  Continued Compliance with Securities Laws.  The Company
          will comply with the 1933 Act and the 1933 Act Regulations and
          the 1934 Act and the 1934 Act Regulations so as to permit the
          completion of the distribution of the Securities as contemplated
          in this Agreement and in the Prospectus.  If at any time when a
          prospectus is required by the 1933 Act to be delivered in
          connection with sales of the Securities, any event shall occur or
          condition shall exist as a result of which it is necessary, in
          the reasonable opinion of counsel for the Underwriters or for the
          Company, to amend the Registration Statement or amend or
          supplement the Prospectus in order that the Prospectus will not
          include any untrue statements of a material fact or omit to state
          a material fact necessary in order to make the statements therein
          not misleading in the light of the circumstances existing at the
          time it is delivered to a purchaser, or if it shall be necessary,
          in the reasonable opinion of such counsel, at any such time to
          amend the Registration Statement or amend or supplement the
          Prospectus in order to comply with the requirements of the 1933
          Act or the 1933 Act Regulations, the Company will promptly
          prepare and file with the Commission, subject to Section 3(b),
          such amendment or supplement as may be necessary to correct such
          statement or omission or to make the Registration Statement or
          the Prospectus comply with such requirements, and the Company
          will furnish to the Underwriters such number of copies of such
          amendment or supplement as the Underwriters may reasonably

          Securities for offering and sale under the applicable securities
          laws of such states and other jurisdictions as the
          Representatives may reasonably designate and to maintain such
          qualifications in effect for a period of not less than one year
          from the date of this Agreement, provided, however, that the

          qualified or to subject itself to taxation in respect of doing
          business in any jurisdiction in which it is not otherwise so
          subject.  In each jurisdiction in which the Securities have been
          so qualified, the Company will file such statements and reports
          as may be required by the laws of such jurisdiction to continue
          such qualification in effect for a period of not less than one
          year from the effective date of the Registration Statement and

          specified in the Prospectus under "Use of Proceeds".

               (i)  Listing.  The Company will use its best efforts to
          effect the listing of the Securities on the New York Stock
          Exchange and the Pacific Exchange.

               (j)  Restriction on Sale of Securities.  During a period of

          swap or any other agreement or any transaction that transfers, in
          whole or in part, directly or indirectly, the economic
          consequence of ownership of the Common Stock, whether any such
          swap or transaction described in clause (i) or (ii) above is to
          be settled by delivery of Common Stock or such other securities,
          in cash or otherwise.  The foregoing sentence shall not apply to

          Stock issued or options to purchase Common Stock granted pursuant
          to existing benefit plans of the Company referred to in the
          Prospectus or pursuant to the Rights, (C) any shares of Common
          Stock issued pursuant to any non-employee director stock plan or
          dividend reinvestment plan or (D) any shares of Common Stock
          issued in connection with mergers or acquisitions completed in

          arising out of any untrue statement or omission or alleged untrue
          statement or omission made in reliance upon and in conformity
          with written information furnished to the Company by any
          Underwriter through Merrill Lynch expressly for use in the
          Registration Statement (or any amendment thereto), or any
          preliminary prospectus or the Prospectus (or any amendment or
          supplement thereto); and provided, further, however, that the 
                                   --------  -------  -------
          Company shall not be liable to an Underwriter to the extent that
          the Company shall sustain the burden of proof that any such loss,
          liability, claim, damage or expense resulted from the fact that
          such Underwriter sold Securities to a person to whom such
          Underwriter failed to send or give, at or prior to the Closing
          Time or Date of Delivery, as the case may be, a copy of the
          Prospectus if (i) the Company has previously furnished copies
          thereof (sufficiently in advance of the Closing Time or Date of
          Delivery, as the case may be), to allow for distribution by the
          Closing Time or Date of Delivery, as the case may be, to the
          Underwriters and the loss, liability, claim, damage or expense of
          such Underwriter resulted from an untrue statement or alleged
          untrue statement or omission contained in or omitted from the
          preliminary prospectus which was corrected in the Prospectus and
          such Prospectus was required by law to be delivered at or prior
          to the written confirmation of sale to such person and (ii) such
          failure to give or send the Prospectus by the Closing Time or the
          Date of Delivery, as the case may be, to the party or parties
          asserting such loss, liability, claim damage or expense would
          have constituted the sole defense to the claim asserted by such
          person.

               (b)  Indemnification of Company, Directors and Officers and
          Selling Shareholders.  Each Underwriter severally agrees to
          indemnify and hold harmless the Company, its directors, each of
          its officers who signed the Registration Statement, and each
          person, if any, who controls the Company within the meaning of
          Section 15 of the 1933 Act or Section 20 of the 1934 Act, and
          each Selling Shareholder and each person, if any, who controls
          any Selling Shareholder within the meaning of Section 15 of the
          1933 Act or Section 20 of the 1934 Act against any and all loss,
          liability, claim, damage and expense described in the indemnity
          contained in subsection (a) of this Section, as incurred, but
          only with respect to untrue statements or omissions, or alleged
          untrue statements or omissions, made in the Registration
          Statement (or any amendment thereto), or any preliminary
          prospectus or the Prospectus (or any amendment or supplement
          thereto) in reliance upon and in conformity with written
          information furnished to the Company by such Underwriter through
          Merrill Lynch expressly for use in the Registration Statement (or
          any amendment thereto) or such preliminary prospectus or the
          Prospectus (or any amendment or supplement thereto).

               (c)  Actions against Parties; Notification.  Each
          indemnified party shall give notice as promptly as reasonably
          practicable to each indemnifying party of any action commenced
          against it in respect of which indemnity may be sought hereunder,
          but failure to so notify an indemnifying party shall not relieve
          such indemnifying party from any liability hereunder to the
          extent it is not materially prejudiced as a result thereof and in
          any event shall not relieve it from any liability which it may
          have otherwise than on account of this indemnity agreement.  In
          the case of parties indemnified pursuant to Section 6(a) above,
          counsel to the indemnified parties shall be selected by Merrill
          Lynch, and, in the case of parties indemnified pursuant to
          Section 6(b) above, counsel to the indemnified parties shall be
          selected by the Company.  An indemnifying party may participate
          at its own expense in the defense of any such action; provided,
          however, that counsel to the indemnifying party shall not (except
          with the consent of the indemnified party) also be counsel to the
          indemnified party.  In no event shall the indemnifying parties be
          liable for fees and expenses of more than one counsel (in
          addition to any local counsel) separate from their own counsel
          for all indemnified parties in connection with any one action or
          separate but similar or related actions in the same jurisdiction
          arising out of the same general allegations or circumstances.  No
          indemnifying party shall, without the prior written consent of
          the indemnified parties, settle or compromise or consent to the
          entry of any judgment with respect to any litigation, or any
          investigation or proceeding by any governmental agency or body,
          commenced or threatened, or any claim whatsoever in respect of
          which indemnification or contribution could be sought under this
          Section 6 or Section 7 hereof (whether or not the indemnified
          parties are actual or potential parties thereto), unless such
          settlement, compromise or consent (i) includes an unconditional
          release of each indemnified party from all liability arising out
          of such litigation, investigation, proceeding or claim and (ii)
          does not include a statement as to or an admission of fault,
          culpability or a failure to act by or on behalf of any
          indemnified party.

               (d)  Settlement without Consent if Failure to Reimburse.  If
          at any time an indemnified party shall have requested an
          indemnifying party to reimburse the indemnified party for fees
          and expenses of counsel, such indemnifying party agrees that it
          shall be liable for any settlement of the nature contemplated by
          Section 6(a) effected without its written consent if (i) such
          settlement is entered into more than 45 days after receipt by
          such indemnifying party of the aforesaid request, (ii) such
          indemnifying party shall have received notice of the terms of
          such settlement at least 30 days prior to such settlement being
          entered into and (iii) such indemnifying party shall not have
          reimbursed such indemnified party in accordance with such request
          prior to the date of such settlement.

               (e)  Other Agreements with Respect to Indemnification.  The
          provisions of this Section shall not affect any agreement among
          the Company and the Selling Shareholders with respect to
          indemnification.

               SECTION 7. Contribution.  If the indemnification provided 
                          ------------
          for in Section 6 hereof is for any reason unavailable to or
          insufficient to hold harmless an indemnified party in respect of
          any losses, liabilities, claims, damages or expenses referred to
          therein, then each indemnifying party shall contribute to the
          aggregate amount of such losses, liabilities, claims, damages and
          expenses incurred by such indemnified party, as incurred, (i) in
          such proportion as is appropriate to reflect the relative
          benefits received by the Company and the Selling Shareholders on
          the one hand and the Underwriters on the other hand from the
          offering of the Securities pursuant to this Agreement or (ii) if
          the allocation provided by clause (i) is not permitted by
          applicable law, in such proportion as is appropriate to reflect
          not only the relative benefits referred to in clause (i) above
          but also the relative fault of the Company and the Selling
          Shareholders on the one hand and of the Underwriters on the other
          hand in connection with the statements or omissions which
          resulted in such losses, liabilities, claims, damages or
          expenses, as well as any other relevant equitable considerations.

               The relative benefits received by the Company and the
          Selling Shareholders on the one hand and the Underwriters on the
          other hand in connection with the offering of the Securities
          pursuant to this Agreement shall be deemed to be in the same
          respective proportions as the total net proceeds from the
          offering of the Securities pursuant to this Agreement (before
          deducting expenses) received by the Company and the Selling
          Shareholders and the total underwriting discount received by the
          Underwriters, in each case as set forth on the cover of the
          Prospectus.

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

               The Company, the Selling Shareholders and the Underwriters
          agree that it would not be just and equitable if contribution
          pursuant to this Section 7 were determined by pro rata allocation
          (even if the Underwriters were treated as one entity for such
          purpose) or by any other method of allocation which does not take
          account of the equitable considerations referred to above in this
          Section 7.  The aggregate amount of losses, liabilities, claims,
          damages and expenses incurred by an indemnified party and
          referred to above in this Section 7 shall be deemed to include
          any legal or other expenses reasonably incurred by such
          indemnified party in investigating, preparing or defending
          against any litigation, or any investigation or proceeding by any
          governmental agency or body, commenced or threatened, or any
          claim whatsoever based upon any such untrue or alleged untrue
          statement or omission or alleged omission.

               Notwithstanding the provisions of this Section 7, no
          Underwriter shall be required to contribute any amount in excess
          of the amount by which the total price at which the Securities
          underwritten by it and distributed to the public were offered to
          the public exceeds the amount of any damages which such
          Underwriter has otherwise been required to pay by reason of any
          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 1933 Act) shall be entitled to
          contribution from any person who was not guilty of such
          fraudulent misrepresentation.

               For purposes of this Section 7, each person, if any, who
          controls an Underwriter within the meaning of Section 15 of the
          1933 Act or Section 20 of the 1934 Act shall have the same rights
          to contribution as such Underwriter, and each director of the
          Company, each officer of the Company who signed the Registration
          Statement, and each person, if any, who controls the Company or
          Selling Shareholder within the meaning of Section 15 of the 1933
          Act or Section 20 of the 1934 Act shall have the same rights to
          contribution as the Company or such Selling Shareholder, as the
          case may be.  The Underwriters' respective obligations to
          contribute pursuant to this Section 7 are several in proportion
          to the number of Initial Securities set forth opposite their
          respective names in Schedule A hereto and not joint.

               The provisions of this Section shall not affect any
          agreement among the Company and the Selling Shareholders with
          respect to contribution.

               SECTION 8.  Representations, Warranties and Agreements to 
                           ---------------------------------------------
          Survive Delivery.  All representations, warranties and agreements
          ----------------
          contained in this Agreement or in certificates of officers of the
          Company or any of its subsidiaries or the Selling Shareholders
          submitted pursuant hereto, shall remain operative and in full
          force and effect, regardless of any investigation made by or on
          behalf of any Underwriter or controlling person, or by or on
          behalf of the Company or the Selling Shareholders, and shall
          survive delivery of the Securities to the Underwriters.

               SECTION 9.  Termination of Agreement.
                           ------------------------

               (a)  Termination; General.  The Representatives may
          terminate this Agreement, by notice to the Company and the
          Selling Shareholders, at any time at or prior to Closing Time or
          the Date of Delivery (i) if there has been, since the time of
          execution of this Agreement or since the respective dates as of
          which information is given in the Prospectus, any material
          adverse change in the condition, financial or otherwise, or in
          the earnings, business affairs or business prospects of the
          Company and its subsidiaries considered as one enterprise,
          whether or not arising in the ordinary course of business, or
          (ii) if there has occurred any material adverse change in the
          financial markets in the United States, any outbreak of
          hostilities or escalation thereof or other calamity or crisis or
          any change or development involving a prospective change in
          national or international political, financial or economic
          conditions, in each case the effect of which is such as to make
          it, in the judgment of the Representatives, impracticable to
          market the Securities or to enforce contracts for the sale of the
          Securities, or (iii) if trading in any securities of the Company
          has been suspended or materially limited by the Commission or the
          New York Stock Exchange or Pacific Exchange, or if trading
          generally on the American Stock Exchange or the New York Stock
          Exchange or in the Nasdaq National Market has been suspended or
          materially limited, or minimum or maximum prices for trading have
          been fixed, or maximum ranges for prices have been required, by
          any of said exchanges or by such system or by order of the
          Commission, the National Association of Securities Dealers, Inc.
          or any other governmental authority, or (iv) if a banking
          moratorium has been declared by either Federal or New York
          authorities.

               (b)  Liabilities. If this Agreement is terminated pursuant
          to this Section, such termination shall be without liability of
          any party to any other party except as provided in Section 4
          hereof, and provided further that Sections 1, 6, 7 and 8 shall
          survive such termination and remain in full force and effect.

               SECTION 10.  Default by One or More of the Underwriters.  If
                            ------------------------------------------
          one or more of the Underwriters shall fail at Closing Time or a
          Date of Delivery to purchase the Securities which it or they are
          obligated to purchase under this Agreement (the "Defaulted
          Securities"), the Representatives shall have the right, within
          24 hours thereafter, to make arrangements for one or more of the
          non-defaulting Underwriters, or any other underwriters, to
          purchase all, but not less than all, of the Defaulted Securities
          in such amounts as may be agreed upon and upon the terms herein
          set forth; if, however, the Representatives shall not have
          completed such arrangements within such 24-hour period, then:

                    (a)  if the number of Defaulted Securities does not
               exceed 10% of the number of Securities to be purchased on
               such date, each of the non-defaulting Underwriters shall be
               obligated, severally and not jointly, to purchase the full
               amount thereof in the proportions that their respective
               underwriting obligations hereunder bear to the underwriting
               obligations of all non-defaulting Underwriters, or

                    (b)  if the number of Defaulted Securities exceeds 10%
               of the number of Securities to be purchased on such date,
               this Agreement or, with respect to any Date of Delivery
               which occurs after the Closing Time, the obligation of the
               Underwriters to purchase and of the Company to sell the
               Option Securities to be purchased and sold on such Date of
               Delivery shall terminate without liability on the part of
               any non-defaulting Underwriter.

               No action taken pursuant to this Section shall relieve any
          defaulting Underwriter from liability in respect of its default.

               In the event of any such default which does not result in a
          termination of this Agreement or, in the case of a Date of
          Delivery which is after the Closing Time, which does not result
          in a termination of the obligation of the Underwriters to
          purchase and the Company to sell the relevant Option Securities,
          as the case may be, either (i) the Representatives or (ii) the
          Company and any Selling Shareholder shall have the right to
          postpone Closing Time or the relevant Date of Delivery, as the
          case may be, for a period not exceeding seven days in order to
          effect any required changes in the Registration Statement or
          Prospectus or in any other documents or arrangements.  As used
          herein, the term "Underwriter" includes any person substituted
          for an Underwriter under this Section 10.

               SECTION 11.  Default by one or more of the Selling 
                            -------------------------------------
          Shareholders or the Company.  (a) If a Selling Shareholder shall
          ---------------------------
          fail at Closing Time to sell and deliver the number of Securities
          which such Selling Shareholder or Selling Shareholders are
          obligated to sell hereunder, and the Company does not exercise
          the right granted below to increase the number of Securities to
          be sold by it hereunder by that number of Securities that are not
          to be sold and delivered by the Selling Shareholder(s), then the
          Underwriters may, at option of the Representatives, by notice
          from the Representatives to the Company and the non-defaulting
          Selling Shareholders, either (a) terminate this Agreement without
          any liability on the fault of any non-defaulting party except
          that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in
          full force and effect or (b) elect to purchase the Securities
          which the non-defaulting Selling Shareholders and the Company
          have agreed to sell hereunder.  No action taken pursuant to this
          Section 11 shall relieve any Selling Shareholder so defaulting
          from liability, if any, in respect of such default.

               In the event the aggregate number of Securities which such
          Selling Shareholder(s) have failed to sell and deliver (the
          "Defaulted Securities") does not exceed 10% of the number of
          Securities to be sold by all Selling Shareholders, the Company
          shall have the right (but not the obligation) to increase the
          number of Securities to be sold by it by an amount equal to the
          number of Defaulted Securities, such right to be exercisable
          within 24 hours of the Closing Time.  In the event of a default
          by any Selling Shareholder as referred to in this Section 11,
          each of the Representatives, the Company and the non-defaulting
          Selling Shareholders shall have the right to postpone Closing
          Time or Date of Delivery for a period not exceeding seven days in
          order to effect any required change in the Registration Statement
          or Prospectus or in any other documents or arrangements.

               (b)  If the Company shall fail at Closing Time or at the
          Date of Delivery to sell the number of Securities that it is
          obligated to sell hereunder, then this Agreement shall terminate
          without any liability on the part of any non-defaulting party;
          provided, however, that the provisions of Sections 1, 4, 6, 7 and
          8 shall remain in full force and effect.  No action taken
          pursuant to this Section shall relieve the Company from
          liability, if any, in respect of such default.

               SECTION 12. Notices.  All notices and other communications 
                           -------
          hereunder shall be in writing and shall be deemed to have been
          duly given if mailed or transmitted by any standard form of
          telecommunication.  Notices to the Underwriters shall be directed
          to the Representatives at North Tower, World Financial Center,
          New York, New York 10281-1201, attention of Russ Robertson;
          notices to the Company shall be directed to it at MDU Resources
          Group, Schuchart Building, 918 East Divide Avenue, Bismarck,

          notices to the Selling Shareholders shall be directed to J.
          Franklin Morse, attorney-in-fact to the Selling Shareholders, at
          3616 NW Eagleview Drive, Albany, OR  97321.

               SECTION 13.  Parties.  This Agreement shall each inure to 
                            -------
          the benefit of and be binding upon the Underwriters, the Company
          and the Selling Shareholders and their respective successors. 
          Nothing expressed or mentioned in this Agreement is intended or
          shall be construed to give any person, firm or corporation, other
          than the Underwriters, the Company and the Selling Shareholders
          and their respective successors and the controlling persons and
          officers and directors referred to in Sections 6 and 7 and their
          heirs and legal representatives, any legal or equitable right,
          remedy or claim under or in respect of this Agreement or any
          provision herein contained.  This Agreement and all conditions
          and provisions hereof are intended to be for the sole and

          Ladies and Gentlemen:

                    We have acted as special counsel to MDU Resources
          Group, Inc., a Delaware corporation (the "Company"), in
          connection with the preparation, execution and delivery of the
          Purchase Agreement (the "Agreement"), dated April    , 1998, by
                                                            ---
          and among the Company, you, as Representatives of the several
          Underwriters named in Schedule A thereto and the persons listed
          in Schedule B thereto, relating to the offering of 2,100,000
          shares of the Company's Common Stock, par value $3.33 per share
          (such shares being hereinafter referred to as the "Common
          Stock"), and the appurtenant preference share purchase rights
          (the "Rights", and together with the Common Stock, the
          "Securities") and the preparation and filing of a Registration
          Statement on Form S-3 (File No. 333-48647) (the "Registration
          Statement") relating to such offering.  All capitalized terms
          used herein without definition shall have the respective meanings
          set forth in the Agreement.

                    This opinion is rendered to you in accordance with
          Section 5(b) of the Agreement.

                    We have examined the Registration Statement and the
          Prospectus, which pursuant to Form S-3 under the Securities Act
          of 1933, as amended (the "Act"), incorporates or is deemed to
          incorporate by reference the Annual Report on Form 10-K of the
          Company for the fiscal year ended December 31, 1997, the Current
          Report on Form 8-K, dated April 16, 1998, and the Registration
          Statement on Form 8-A of the Company, dated November 17, 1988
          (the "Exchange Act Documents"), each as filed under the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"). 
          In addition, we have examined, and have relied as to matters of
          fact upon, the documents delivered to you at the closing (except
          the certificates representing the Common Stock, of which we have
          examined a specimen), and upon originals or copies, certified or
          otherwise identified to our satisfaction, of such corporate
          records, agreements, documents and other instruments and such
          certificates or comparable documents of public officials and of
          officers and representatives of the Company, and have made such
          other and further investigations, as we have deemed relevant and
          necessary as a basis for the opinions hereinafter set forth.

                    In such examination, we have assumed the genuineness of
          all signatures, the legal capacity of natural persons, the
          authenticity of all documents submitted to us as originals, the
          conformity to original documents of all documents submitted to us
          as certified or photostatic copies, and the authenticity of such
          latter documents.

                    Based upon the foregoing, and subject to the
          qualifications and limitations stated herein, we are of the
          opinion that:

               (i)  The Company is validly existing as a corporation in
          good standing under the laws of the State of Delaware.

               (ii) The Company is duly qualified as a foreign corporation
          to transact business and is in good standing in Montana, North
          Dakota, South Dakota and Wyoming.

               (iii)     The Common Stock to be purchased by the
          Underwriters from the  Company has been duly authorized for
          issuance and sale to the Underwriters pursuant to the Agreement
          and, when issued and delivered by the Company pursuant to the
          Agreement against payment of the consideration set forth therein,
          will be validly issued and fully paid and non-assessable, and no
          holder of the Common Stock is subject to personal liability by
          reason of being such a holder.  The Common Stock to be purchased
          from the Selling Shareholders has been duly authorized and
          validly issued and is fully paid and non-assessable.

               (iv) The issuance and sale of the Securities by the Company
          and the sale of the Securities by the Selling Shareholders are
          not subject to the preemptive or other similar rights of any
          securityholder of the Company.

               (v)  The Agreement and the Custody Agreement and Power of
          Attorney each has been duly authorized, executed and delivered by
          the Company.  The Rights Agreement, dated as of November 3, 1988
          (the "Rights Agreement"), between the Company and Norwest Bank
          Minnesota N.A., as Rights Agent, has been duly authorized,
          executed and delivered by the Company; and when the Rights shall
          have been issued in accordance with the Agreement, the Rights to
          be purchased by the Underwriters will have been duly and validly
          issued.

               (vi) The Registration Statement has become effective under
          the Act, any required filing of the Prospectus pursuant to Rule
          424(b) has been made in the manner and within the time period
          required by Rule 424(b); and, to the best of our knowledge, no
          stop order suspending the effectiveness of the Registration
          Statement has been issued under the Act and no proceedings for
          that purpose have been instituted or are pending or threatened by
          the Commission.

               (vii)     The Registration Statement, the Prospectus,
          excluding the Exchange Act Documents, and each supplement to the
          Registration Statement and Prospectus, excluding the Exchange Act
          Documents, as of the time the Registration Statement became
          effective, and the Prospectus as of the date it was filed
          pursuant to Rule 424(b) under the Act (other than the financial
          statements and supporting schedules and other financial data
          included therein, or the information relating to the Company's
          interest in oil and natural gas reserves attributed to Ralph E.
          Davis Associates, Inc. or the information concerning the lignite
          coal reserves of Knife River Coal Mining Company attributed to
          Paul Weir International Mining Consultants contained therein,
          upon which we express no opinion (collectively, the "Excepted
          Information")) complied as to form in all material respects with
          the requirements of the Act and the 1933 Act Regulations.

               (viii)    The Exchange Act Documents (other than the
          Excepted Information, upon which we express no opinion), when
          they became effective or were filed with the Commission, as the
          case may be, complied as to form in all material respects with
          the requirements of the Act or the Exchange Act, as applicable,
          and the rules and regulations of the Commission thereunder.

               (ix) The form of certificate used to evidence the Common
          Stock complies in all material respects with all applicable
          statutory requirements, with any applicable requirements of the
          Restated Certificate of Incorporation and by-laws of the Company
          and the requirements of the New York Stock Exchange and the
          Pacific Exchange.

               (x)  The information in the Prospectus under "Description of
          Common Stock and Rights" and in the Registration Statement under
          Item 15, to the extent that it constitutes matters of law,
          summaries of legal matters, the Company's Restated Certificate of
          Incorporation and by-laws, or legal proceedings or legal
          conclusions, has been reviewed by us and is correct in all
          material respects.

               (xi) The Federal Energy Regulatory Commission (the "FERC"),
          the Montana Public Service Commission and the Public Service
          Commission of Wyoming have authorized the issuance and sale of
          the Securities in the manner contemplated by the Agreement, and,
          to the best of our knowledge, said authorizations are still in
          full force and effect.  No filing with, or authorization,
          approval, consent, license, order, registration, qualification or
          decree of, any court or governmental authority or agency,
          domestic or foreign (other than as described above, and under the
          Act and the 1933 Act Regulations, which have been obtained, or as
          may be required under the securities or blue sky laws of the
          various states, as to which we express no opinion) is necessary
          or required in connection with the due authorization, execution
          and delivery of the Agreement or for the offering, issuance, sale
          or delivery of the Securities, except such as may be required in
          connection with post-filing requirements with the FERC due after
          the date hereof.

               (xii)     The execution, delivery and performance of the
          Agreement and the consummation of the transactions contemplated
          in the Agreement and in the Registration Statement (including the
          issuance and sale of the Securities) and compliance by the
          Company with its obligations under the Agreement do not and will
          not, whether with or without the giving of notice or lapse of
          time or both, conflict with or constitute a breach of, or default
          or Repayment Event (as defined in Section 1(a)(xii) of the
          Agreement) under or result in the creation or imposition of any
          lien, charge or encumbrance upon any property or assets of the
          Company pursuant to any contract, indenture, mortgage, deed of
          trust, loan or credit agreement, note, lease or any other
          agreement or instrument, each of a material nature and known to
          us, to which the Company is a party or by which it may be bound,
          or to which any of the property or assets of the Company is
          subject (except for such conflicts, breaches or defaults or
          liens, charges or encumbrances or Repayment Events that would not
          have a Material Adverse Effect), nor will such action result in
          any violation of the provisions of the Restated Certificate of
          Incorporation or by-laws of the Company, or any applicable law,
          statute, rule, regulation, judgment, order, writ or decree, known
          to us, of any government, government instrumentality or court,
          domestic or foreign, having jurisdiction over the Company or any
          of its properties, assets or operations.

                    We have not independently verified the accuracy,
          completeness or fairness of the statements made or included in
          the Registration Statement, the Prospectus or the Exchange Act
          Documents and take no responsibility therefor, except to the
          extent set forth in paragraph (x) above.  In the course of
          preparation by the Company of the Registration Statement and the
          Prospectus, we participated in conferences with certain of its
          officers and employees, with its General Counsel, with your
          representatives and with representatives of Arthur Andersen LLP,
          the independent accountants who examined certain of the financial
          statements included in the Exchange Act Documents.  Based on our
          examination of the Registration Statement, the Prospectus and the
          Exchange Act Documents, our investigations made in connection
          with the preparation of the Registration Statement and the
          Prospectus and our participation in the conferences referred to
          above, nothing has come to our attention that would lead us to
          believe that the Registration Statement (except for the Excepted
          Information, upon which we make no statement), at the time such
          Registration Statement became effective, contained an untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading or that the Prospectus (except for the
          Excepted Information, upon which we make no statement), as of the
          date the Prospectus was filed under Rule 424(b) under the Act or
          on the date hereof, included or includes an untrue statement of a
          material fact or omitted or omits to state a material fact
          necessary in order to make the statements therein, in the light
          of the circumstances under which they were made, not misleading.

                    We are members of the Bar of the State of New York and
          do not hold ourselves out as experts in the laws of any other
          state.  We express no opinion as to the laws of any jurisdiction
          other than the laws of the State of New York, the General
          Corporation Law of the State of Delaware, and the Federal laws of
          the United States of America.

                    In rendering this opinion, we have relied as to all
          matters of Montana, North Dakota, South Dakota and Wyoming law
          and, as to the matters addressed therein, with your consent, upon
          the opinion addressed to you of even date herewith of Lester H.
          Loble, II, Esq., Bismarck, North Dakota, the General Counsel of
          the Company, and we believe that we and the Underwriters are
          justified in relying upon such opinion.

                    This opinion is rendered to you in connection with the
          above-described transaction.  This opinion may not be relied upon
          by you for any other purpose, or relied upon by or furnished to
          any other person, firm or corporation (other than the several
          Underwriters), other than Lester H. Loble, II, Esq., the
          Company's General Counsel, to the extent set forth in his opinion
          of even date herewith addressed to you, without our prior
          consent.

                                             Very truly yours,

          Ladies and Gentlemen:

                    I am General  Counsel of MDU  Resources Group, Inc.,  a
          Delaware  corporation  (the "Company"),  and  am delivering  this
          opinion   in   connection  with   the  Purchase   Agreement  (the
          "Agreement"), dated April  , 1998, by and among the Company, you, as
                                   --
          Representatives of  the several Underwriters named  in Schedule A
          thereto and the persons listed in Schedule B thereto, relating to
          the offering of  2,100,000 shares of the  Company's Common Stock,
          par value $3.33 per share (such shares being hereinafter referred
          to  as the "Common Stock"), and  the appurtenant preference share
          purchase  rights  (the "Rights",  and  together  with the  Common
          Stock,  the "Securities")  and the  preparation and  filing  of a
          Registration  Statement on  Form S-3  (File No.  333-48647)  (the
          "Registration  Statement")  relating  to   such  offering.    All
          capitalized terms  used herein without definition  shall have the
          respective meanings set forth in the Agreement.

                    This  opinion is  rendered  to you  in accordance  with
          Section 5(b) of the Agreement.

                    I  have examined  the  Registration  Statement and  the
          Prospectus, which pursuant  to Form S-3 under  the Securities Act
          of 1933, as  amended (the  "Act"), incorporates or  is deemed  to
          incorporate  by reference the Annual  Report on Form  10-K of the
          Company  for the fiscal year ended December 31, 1997, the Current
          Report  on Form 8-K, dated  April 16, 1998,  and the Registration
          Statement on Form  8-A of  the Company, dated  November 17,  1988
          (the  "Exchange   Act  Documents"),  each  as   filed  under  the
          Securities Exchange Act of 1934, as amended (the "Exchange Act").
          In  addition, I have examined,  and have relied  as to matters of
          fact  upon, the documents delivered to you at the closing (except
          the certificates representing the Common  Stock, of which I  have
          examined a specimen), and upon originals or copies, certified  or
          otherwise  identified  to  my  satisfaction,  of  such  corporate
          records,  agreements,  documents and  other instruments  and such
          certificates or  comparable documents of public  officials and of
          officers  and representatives of the Company,  and have made such
          other and further  investigations, as I have deemed  relevant and
          necessary as a basis for the opinions hereinafter set forth.

                    In such examination, I  have assumed the genuineness of
          all  signatures,  the  legal  capacity of  natural  persons,  the
          authenticity of all documents  submitted to me as originals,  the
          conformity to original documents of all documents submitted to me
          as certified or photostatic copies, and  the authenticity of such
          latter documents.

                    Based  upon   the  foregoing,   and   subject  to   the
          qualifications and limitations stated herein, I am of the opinion
          that:

               (i)  The Company  has been duly incorporated  and is validly
          existing as a  corporation in good standing under the laws of the
          State of Delaware.

               (ii) The Company  has corporate power and  authority to own,
          lease and operate its  properties and to conduct its  business as
          described in the  Prospectus and  to enter into  and perform  its
          obligations  under the Agreement.   The  Company holds  valid and
          subsisting  franchises, licenses  and  permits authorizing  it to
          carry on the utility business  in which it is engaged, except  as
          may be stated or referred to in the Prospectus.

               (iii)     The  Company   is  duly  qualified  as  a  foreign
          corporation to  transact  business and  is  in good  standing  in
          Montana, North  Dakota,  South  Dakota and  Wyoming  and  is  not
          required,  whether  by reason  of  the  ownership or  leasing  of
          property or the conduct of business, to be qualified in any other
          jurisdiction, except  where the failure so to qualify or to be in
          good standing would not result in a Material Adverse Effect.

               (iv) The outstanding common stock  of the Company is  as set
          forth in the  Prospectus in  the row entitled  "Shares of  Common
          Stock  outstanding   at  March   31,  1998"  under   the  caption
          "Capitalization" (except  for subsequent  issuances, if  any, (A)
          pursuant  to  the  Agreement  or (B)  pursuant  to  reservations,
          agreements  or   employee  benefit  plans  referred   to  in  the
          Prospectus  or  (C)  pursuant  to  the  exercise  of  convertible
          securities  or  options  referred to  in  the  Prospectus  or (D)
          [Angell,  Pouk] shares  issued  pursuant to  acquisitions by  the
          Company); the shares of  issued and outstanding capital  stock of
          the  Company, including the Common  Stock to be  purchased by the
          Underwriters  from  the  Selling  Shareholders,  have  been  duly
          authorized  and  validly issued  and  are  fully  paid  and  non-
          assessable, and none  of the outstanding shares  of capital stock
          of the Company was issued in violation of the preemptive or other
          similar rights of any securityholder of the Company.

               (v)  Each  Subsidiary  has  been  duly incorporated  and  is
          validly existing as a corporation in good standing under the laws
          of the jurisdiction of its incorporation, has corporate power and
          authority to own, lease and operate its properties and to conduct
          its business as described in the Prospectus and is duly qualified
          as  a foreign  corporation to  transact business  and is  in good
          standing  in each  jurisdiction  in which  such qualification  is
          required,  whether by  reason  of  the  ownership or  leasing  of
          property  or the conduct of business, except where the failure so
          to  qualify  or to  be in  good standing  would  not result  in a
          Material  Adverse Effect;  except as  otherwise disclosed  in the
          Registration Statement, all of the issued and outstanding capital
          stock of  each Subsidiary  has been duly  authorized and  validly
          issued,  is fully paid and non-assessable and,  to the best of my
          knowledge,  is   owned  by  the  Company,   directly  or  through
          subsidiaries, free and clear  of any security interest, mortgage,
          pledge,  lien,   encumbrance,  claim  or  equity;   none  of  the
          outstanding shares  of capital stock of any Subsidiary was issued
          in  violation  of  the  preemptive   or  similar  rights  of  any
          securityholder of such Subsidiary.

               (vi) To  the best of my  knowledge, there is  not pending or
          threatened   any   action,    suit,   proceeding,   inquiry    or
          investigation, to which the Company or any subsidiary is a party,
          or to  which the  property of  the Company  or any subsidiary  is
          subject, before or brought by any court or governmental agency or
          body, domestic  or foreign, which might reasonably be expected to
          result in a Material Adverse Effect, or which might reasonably be
          expected  to materially  and adversely  affect the  properties or
          assets   thereof  or   the  consummation   of   the  transactions
          contemplated in the  Agreement or the performance by  the Company
          of its obligations thereunder.

               (vii)     The   information   in   the    Prospectus   under
          "Description  of  Common  Stock  and Rights"  in  the  Prospectus
          Supplement and  in the Registration  Statement under Item  15, to
          the extent that it constitutes matters of law, summaries of legal
          matters, the Company's charter  and by-laws, or legal proceedings
          or legal  conclusions, has been reviewed by  me and is correct in
          all material respects.

               (viii)    To the best of my knowledge, there are no material
          statutes  or regulations that are required to be described in the
          Prospectus that are not described as required.

               (ix) All  descriptions  in  the  Registration  Statement  of
          contracts  and  other  documents  to  which the  Company  or  its
          subsidiaries  are a party are accurate  in all material respects,
          to  the best of my knowledge, there are no franchises, contracts,
          indentures,  mortgages, loan agreements,  notes, leases  or other
          instruments, each of a material  nature, required to be described
          or referred  to in the Registration  Statement or to be  filed as
          exhibits  thereto  other  than  those described  or  referred  to
          therein  or  filed  or  incorporated  by  reference  as  exhibits
          thereto, and  the descriptions thereof or  references thereto are
          correct in all material respects.

               (x)  To  the best of  my knowledge, neither  the Company nor
          any subsidiary is in violation  of its charter or by-laws and  no
          default  by the  Company  or any  subsidiary  exists in  the  due
          performance  or observance of any material obligation, agreement,
          covenant  or  condition  contained  in any  contract,  indenture,
          mortgage,  loan  agreement, note,  lease  or  other agreement  or
          instrument that is  described or referred to  in the Registration
          Statement or the Prospectus or filed or incorporated by reference
          as an exhibit to the Registration Statement.

               (xi) The  Federal Energy Regulatory Commission (the "FERC"),
          the  Montana Public  Service  Commission and  the Public  Service
          Commission  of Wyoming have  authorized the issuance  and sale of
          the Securities in the manner contemplated by the Agreement,  and,
          to the best  of my  knowledge, said authorizations  are still  in
          full  force  and  effect.   No  filing  with,  or  authorization,
          approval, consent, license, order, registration, qualification or
          decree  of,  any  court  or  governmental  authority  or  agency,
          domestic or foreign (other than as described above, under the Act
          and the 1933 Act Regulations, which have been obtained, or as may
          be required  under the securities or blue sky laws of the various
          states,  as  to  which I  express  no  opinion)  is necessary  or
          required in connection with  the due authorization, execution and
          delivery  of the Agreement or for the offering, issuance, sale or
          delivery of the  Securities, except  such as may  be required  in
          connection with post-filing requirements  with the FERC due after
          the date hereof.

               (xii)     The  execution,  delivery and  performance  of the
          Agreement and  the consummation of  the transactions contemplated
          in the Agreement and in the Registration Statement (including the
          issuance  and sale  of  the  Securities)  and compliance  by  the
          Company  with its obligations under the Agreement do not and will
          not, whether  with or without  the giving  of notice or  lapse of
          time or both, conflict with or constitute a breach of, or default
          or Repayment  Event  (as  defined  in Section  1(a)(xii)  of  the
          Agreement) under or result  in the creation or imposition  of any
          lien,  charge or encumbrance upon  any property or  assets of the
          Company or  any subsidiary  pursuant to any  contract, indenture,
          mortgage, deed of trust, loan or credit agreement, note, lease or
          any  other agreement or instrument, each of a material nature and
          known to me, to which the Company or any subsidiary is a party or
          by which it or any of them may  be bound, or to which any of  the
          property  or assets of the  Company or any  subsidiary is subject
          (except  for  such  conflicts,  breaches or  defaults  or  liens,
          charges or encumbrances or Repayment Events that would not have a
          Material  Adverse Effect),  nor will  such action  result  in any
          violation  of the  provisions of  the charter  or by-laws  of the
          Company or any subsidiary, or any applicable  law, statute, rule,
          regulation,  judgment, order, writ or decree, known to me, of any
          government,  government  instrumentality  or court,  domestic  or
          foreign, having  jurisdiction over the Company  or any subsidiary
          or any of their respective properties, assets or operations.

                    I   have  not  independently   verified  the  accuracy,
          completeness or fairness  of the statements  made or included  in
          the Registration  Statement, the  Prospectus or the  Exchange Act
          Documents  and take  no  responsibility therefor,  except to  the
          extent  set forth  in paragraph  (vii) above.   In the  course of
          preparation by  the Company of the Registration Statement and the
          Prospectus,  I participated  in conferences  with certain  of its
          officers and employees, with other counsel  for the Company, with
          your representatives and with representatives of Arthur  Andersen
          LLP,  the independent  accountants  who examined  certain of  the
          financial  statements  included in  the  Exchange Act  Documents.
          Based  on  my  examination  of the  Registration  Statement,  the
          Prospectus and the Exchange Act Documents, my investigations made
          in connection with the  preparation of the Registration Statement
          and  the  Prospectus  and  my participation  in  the  conferences
          referred  to above, nothing has  come to my  attention that would
          lead me to  believe that the  Registration Statement (except  for
          the Excepted Information, upon which I make no statement), at the
          time such Registration  Statement became effective, contained  an
          untrue  statement  of  a material  fact  or  omitted  to state  a
          material  fact required to be stated therein or necessary to make
          the  statements therein  not  misleading or  that the  Prospectus
          (except  for the  Excepted  Information,  upon  which I  make  no
          statement),  as of the date  the Prospectus was  filed under Rule
          424(b) under the Act or on the date hereof, included  or includes
          an untrue  statement of a  material fact or  omitted or omits  to
          state a material fact  necessary in order to make  the statements
          therein,  in the light of the circumstances under which they were
          made, not misleading.

                    I am a member of the North Dakota and Montana Bars  and
          do not hold  myself out  as an expert  on the laws  of any  other
          state, but I have made a study of the laws of such states insofar
          as  such  laws are  involved in  the  conclusions stated  in this
          opinion.   As to  matters of the  General Corporation  Law of the
          State of Delaware  and the Federal  laws of the United  States of
          America,  I have relied, with  your consent, upon  the opinion of
          Reid &  Priest LLP, counsel to  the Company, a copy  of which has
          been delivered to you.

                    This opinion is rendered to you in connection with  the
          above-described transaction.  This opinion may not be relied upon
          by you for any other  purpose, or relied upon by or  furnished to
          any other person,  firm or  corporation (other  than the  several
          Underwriters),  other than Reid & Priest  LLP, special counsel to
          the  Company, and Berlack, Israels & Liberman LLP, counsel to the
          Underwriters, to the extent  set forth in their opinions  of even
          date herewith addressed to you, without my prior written consent.

                                                  Very truly yours,



                                                  Lester H. Loble, II
                                                  General Counsel

                    Incorporated
          Donaldson, Lufkin & Jenrette Securities Corporation
          Edward D. Jones & Co., L.P.
          Lehman Brothers, Inc.
          as Representatives of the several Underwriters
          C/O Merrill Lynch & Co.
               Merrill Lynch, Pierce, Fenner & Smith

          New York, New York  10281-1209

          Ladies and Gentlemen:

               In connection with that certain Purchase Agreement dated
          April 21, 1998, (the "Purchase Agreement") between Merrill Lynch
          & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and
          each of the other Underwriters named in Schedule A attached
          thereto (collectively, the "Underwriters"), MDU Resources Group,
          Inc., a Delaware Corporation and the Selling Shareholders (the
          "Selling Shareholders") listed in Schedule B thereto, we advise
          you that we represent the Selling Shareholders, as listed in
          Schedule B of the Purchase Agreement, in connection with the
          transactions set forth and described in the Purchase Agreement. 
          The capitalized terms used herein and not otherwise defined have
          the meaning assigned in the Purchase Agreement.

               In connection with the transactions set forth and described
          in the Purchase Agreement, we further advise you that we have
          examined and are familiar with the originals or copies of the
          following documents:

               The Purchase Agreement, dated April 21, 1998, entered into
          by and between Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner
          and Smith Incorporated, and each of the other Underwriters named
          in Schedule A attached thereto,  MDU Resources Group, Inc., a
          Delaware Corporation, and the Selling Shareholders named and
          listed in Schedule B attached thereto.

               The Custody Agreement and Power of Attorney, dated as of the
          April 21, 1998, by and among MDU Resources Group, Inc., a
          Delaware Corporation, the Selling Shareholders (as identified on
          Exhibit A thereto), J. Franklin Morse, as attorney-in-fact for
          the Selling Shareholders, and Norwest Bank Minnesota, N.A., as
          custodian.

               The Stock Disposition Agreement, dated as of March 5, 1998,
          entered into by and among MDU Resources Group, Inc. and the
          Shareholders listed on Exhibit I thereto (former holders of
          shares of capital stock of Morse Bros., Inc.).

               The Stock Disposition Agreement, dated as of March 5, 1998,
          entered into by and among MDU Resources Group, Inc., Dennis L.
          Smallwood and R. Gary Ferguson.

               The Stockholders' Agreement, dated as of March 5, 1998, by
          and among MDU Resources Group, Inc. and each of the stockholders
          whose names appear on the signature page thereof (former holders
          of shares of capital stock of Morse Bros., Inc.).

               The Stockholders' Agreement, dated as of March 5, 1998, by
          and among MDU Resources Group, Inc. and each of the stockholders
          whose names appear on the signature page thereof (Dennis L.
          Smallwood and R. Gary Ferguson).

               Certificates representing the Securities to be sold by the
          Selling Shareholders and the related stock powers executed by the
          respective Selling Shareholders.

               The Prospectus, for the sale of 2,100,000 shares of MDU
          Resources Group, Inc. common stock with supplement dated April
          21, 1998.

               Based upon our examination and review of the documents above
          described, and such further documents and materials as we deemed
          necessary to review for purposes of rendering this opinion, we
          are of the opinion that:

     (1)  No filing with, or consent, approval, authorization,
          license, order, registration, qualification or decree of, any
          court or governmental authority or agency, domestic or foreign
          (other than the issuance of the order of the Commission declaring
          the Registration Statement effective and such authorizations,
          approvals, or consents as may be necessary under state securities
          laws, as to which we express no opinion), is necessary or
          required to be obtained by the Selling Shareholders for the
          performance by each Selling Shareholder of each Selling
          Shareholder's obligations under the Purchase Agreement or under
          the Custody Agreement and Power of Attorney, or in connection
          with the offer, sale or delivery of the Securities.

     (2)  The Custody Agreement and Power of Attorney has been
          duly authorized, executed and delivered by each Selling
          Shareholder.  The Courts of the State of Oregon, if properly
          presented with the question, should give effect to the choice-of-
          law provisions contained in the Custody Agreement and Power of
          Attorney (the "Agreement"), which by their terms are governed by
          the laws of the State of New York, subject to the application of
          the law of other states to the extent that such a court may
          conclude that to give such effect to such provisions would
          contravene the public policy of the State of Oregon.  Should,
          however, an Oregon court elect the internal laws of the State of
          Oregon as the choice of law for the interpretation and
          enforcement of the Agreement, the Agreement would be the valid
          and binding obligation of each Selling Shareholder enforceable
          against such Selling Shareholder in accordance with its terms
          under the internal laws of the State of Oregon, except as such
          enforceability may be limited by:  (i) the effect of general
          principles of equity; (ii) the effect of federal and state
          securities laws, rules and regulations, and public policy as they
          may limit rights to indemnification; and (iii) the effect of
          bankruptcy, insolvency and other similar laws relating to or
          affecting the rights of creditors generally.

     (3)  The Purchase Agreement has been duly authorized,
          executed and delivered by or on behalf of each Selling
          Shareholder.

     (4)  J. Franklin Morse, the Attorney-in-Fact, has been duly
          authorized by each Selling Shareholder to deliver the Securities
          on behalf of each Selling Shareholder in accordance with the
          terms of the Purchase Agreement.

     (5)  The execution, delivery and performance of the Purchase
          Agreement and the Custody Agreement and Power of Attorney and the
          sale and delivery of the Securities and the consummation of the
          transactions contemplated in the Purchase Agreement and in the
          Registration Statement and compliance by each Selling Shareholder
          with its obligations under the Purchase Agreement have been duly
          authorized by all necessary action on the part of such Selling
          Shareholder and to the best of our knowledge do not and will not,
          whether with or without the giving of notice or passage of time
          or both, conflict with or constitute a breach of, or default
          under or result in the creation or imposition of any tax, lien,
          charge or encumbrance upon the Securities or any property or
          assets of such Selling Shareholder pursuant to, any contract,
          indenture, mortgage, deed or trust, loan or credit agreement,
          note, license, lease or other instrument or agreement to which
          any selling Shareholder is a party or by which they may be bound,
          or to which any of the property or assets of any Selling
          Shareholder may be subject nor to the best of our knowledge will
          such action result in any violation of the provisions of the
          charter or by-laws of any Selling Shareholder, if applicable, or
          any law, administration regulation, judgment or order of any
          governmental agency or body or any administrative or court decree
          having jurisdiction over such Selling Shareholder or any of its
          properties.

     (6)  To the best of our knowledge, each Selling Shareholder
          has valid and marketable title to the Securities to be sold by
          such Selling Shareholder pursuant to the Purchase Agreement, free
          and clear of any pledge, lien, security interest, charge, claim,
          equity or encumbrance of any kind, and has full right, power and
          authority to sell, transfer and deliver such Securities pursuant
          to the Purchase Agreement.  By delivery of a certificate or
          certificates therefor such Selling Shareholder will transfer to
          the Underwriters who have purchased such Securities pursuant to
          the Purchase Agreement (without notice of any defect in the title
          of such Selling Shareholder and who are otherwise bona fide
          purchasers for purposes of the Uniform Commercial Code) valid and
          marketable title to such Securities free and clear of any pledge,
          lien, security interest, charge, claim, equity or encumbrance of
          any kind.

               Based on our examination of the information included in the
          Prospectus under the caption "Selling Shareholders," nothing has
          come to our attention that would lead us to believe that, as of
          the date the Prospectus was filed under Rule 424(b) under the
          1933 Act and as of the Closing Time, such information included or
          includes an untrue statement of a material fact or omitted or
          omits to state a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which
          they were made, not misleading.

               We are licensed to practice law in the State of Oregon and
          do not hold ourselves out as experts in the laws of any other
          state.

                         WEATHERFORD, THOMPSON, QUICK & ASHENFELTER, P.C.
