     WITNESSETH:

     WHEREAS, NSP is engaged in the business of generating,
transmitting and distributing electric power and energy in the States
of Minnesota, North Dakota, and South Dakota; and

     WHEREAS, SMMPA is a public body corporate and politic and
instrumentality of the State of Minnesota and is empowered to engage in
the business of generating and transmitting electric power and energy
to its members; and

     WHEREAS, the Parties are signatories to the Sherburne County
Generating Unit No. 3 Ownership and Operating Agreement dated March 11,
1982 (Ownership Agreement) providing for joint ownership and operation
of Unit 3 at the Sherco Plant Site; and

     WHEREAS, SMMPA's share of the electrical output of Sherco 3 will
be delivered to the switching substation located on the Sherco Plant
Site; and

     WHEREAS, the Parties are signatories to the Shared Transmission
Agreement ("STS Agreement") dated November 18, 1981, providing for
certain transmission services for SMMPA members on NSP s system; and

     WHEREAS, in addition to the SMMPA members connected to the NSP
system, all other SMMPA members are interconnected with systems of
either the Dairyland Power Cooperative ("DPC") or Interstate Power
Company ("ISP"); and

     WHEREAS, SMMPA is responsible to deliver a portion of its share
of the Sherco 3 output to its members interconnected to DPC's and ISP's
transmission systems; and

     WHEREAS, SMMPA has entered or will enter into shared transmission

interconnections between said signatory parties; and

     WHEREAS, NSP is willing to deliver a portion of SMMPA's power and
energy from Sherco 3 to ISP and DPC points of interconnection with NSP
pursuant to the terms and conditions of this Agreement.

     NOW THEREFORE, the Parties hereto agree to the following:

                         ARTICLE I
               NSP's Transmission Obligation

     1.01 SMMPA will be delivering to NSP a certain amount of its
Sherco 3 power and energy at the 345 Kv switching station at the Sherco
Plant Site.  The maximum amount of power and energy to be delivered by
SMMPA to NSP shall be determined by subtracting SMMPA's estimated peak
load delivery under the STS Agreement from SMMPA's 300 MW ownership in
Sherco 3.  Such amount shall be considered NSP's maximum transmission
obligation and when determined shall be stated in an amendment to this
Section.  NSP agrees to deliver an equivalent amount of power and
energy, less losses in accordance with Section 4.03 hereof, to ISP and
DPC points of interconnection with NSP.

     1.02 If SMMPA pays the total transmission obligation determined
pursuant to Article II hereof prior to Sherco 3 commercial operation,
NSP agrees to deliver power and energy purchased by SMMPA from other
sources and delivered to NSP to points of inter-connection with DPC and
ISP, providing NSP has transmission capacity available as determined by
NSP.  NSP's obligation shall not exceed the maximum transmission
obligation determined in Section 1.01 hereof.  Line losses shall be
mutually agreed to at the time.

                        ARTICLE II
              SMMPA's Transmission Obligation

     2.01 For the transmission services provided by NSP in Article 
I hereof, SMMPA shall construct new transmission facilities in NSP's
transmission system and/or purchase existing NSP transmission facilities
of 345 Kv and above, which are no more than 10 years old at date of this
Agreement, at NSP's original cost depreciated, as determined by NSP,
equal to an investment of 73.00/Kw in 1981 dollars multiplied by NSP's
maximum transmission obligation pursuant to Section 1.01 hereof and
adjusted thereafter in accordance with Section 2.02 hereof.  SMMPA shall
make its best effort to fulfill such transmission investment obligation
by the commercial operation of Sherco 3.  In the event the SMMPA
transmission investment has not been fulfilled by the commercial
operation date of Sherco 3, SMMPA shall pay NSP for transmission service
for the balance owed NSP based on the following formula:

     Monthly Charge = X x Y x T
                     --   -
                     12   Z

     Where:

        T   =   Maximum transmission obligation pursuant to Section
                1.01, hereof.
        X   =   NSP's annual firm power wheeling rate as accepted
                for filing by the Federal Energy Regulatory
                Commission expressed in $/Kw.
        Y   =   SMMPA's remaining investment obligation owed NSP.
        Z   =   SMMPA's total investment obligation pursuant to
                Article II, hereof.

        2.02 SMMPA's investment obligation stated in Section 2.01
shall be adjusted by the smaller of the following:

(a)     The proportionate change between January 1, 1981 and the date
        of SMMPA's investment based on the Handy-Whitman Total
        Transmission Plant Index in the North Central Region, or

(b)     6% per annum increase from January 1, 1981 and the date of
        SMMPA's investment.

        2.03 NSP shall have the unrestricted right to use the
transmission facilities provided by SMMPA as set forth in Section 2.01
hereof.

                        ARTICLE III
                   Transmission Buy Back

        3.01 At the time Sherco 3 is retired by the Parties pursuant
to the Ownership Agreement, NSP shall purchase the transmission
facilities owned by SMMPA pursuant to Article II hereof for SMMPA's
original costs, less depreciation at 2.7% per year.

        3.02 If Sherco 3 does not reach commercial operation, by
January 1, 1991, NSP shall be obligated to purchase the transmission
facilities owned by SMMPA pursuant to Article II hereof for SMMPA's
original costs plus interest from the date of SMMPA's investment to
NSP's purchase.  The interest rate shall be the average of: 1) cost of
capital for NSP approved in the most recent Minnesota jurisdiction
electric rate case and 2) the average interest rate of SMMPA's
outstanding revenue bond issues.


                        ARTICLE IV
                         Operation

        4.01 Operation and Maintenance

        NSP shall assume full responsibility for the operation, and
SMMPA shall assume full responsibility for the proper maintenance and
replacement of the transmission facilities to be constructed or
purchased by SMMPA pursuant to Article II hereof.  SMMPA shall pay NSP
for operation of these facilities at NSP's average operating costs per
mile for the same voltage class.  The cost of maintenance and
replacement of equipment and facilities, shall be borne by the Party
providing such equipment and facilities unless such maintenance was
occasioned by the negligence of the other Party, in which event such
cost shall be borne by the negligent Party.  Through mutual agreement,
one Party may accept the maintenance responsibility for all or a portion
of the other Party s facilities on a continuous or temporary basis.  In
such instances, the owning Party shall pay the Party performing the
maintenance for the cost incurred.  In the event the owning Party
requests the other Party to perform maintenance work on facilities for
which mutual agreement for performing the maintenance has not been
obtained, or in the event of an emergency requiring repair or
replacement, the other Party may perform the necessary work on the
owning Party's facility, and within fifteen (15) days of the billing
therefore, the owning Party shall reimburse the other Party for the cost
thereof, which shall include the actual cost of labor, materials,
transportation and applicable overheads.  Late payments shall bear
interest at the average daily prime rates published in the "Money Rates"
section of the Wall Street Journal for each day from the date due to
date of payment.

        4.02 SMMPA shall pay NSP for SMMPA's share of NSP's cost of
providing control of the transmission system for delivery of SMMPA's
Sherco 3 power and energy to DPC and ISP points of inter-connection with
NSP in accordance with Exhibit A, attached hereto and made a part
hereof.

        4.03 Delivery and Losses

        When SMMPA schedules generation from Sherco 3 for delivery to
the DPC or ISP systems, the power and energy scheduled shall be
delivered to such system less losses.  Such losses shall be determined
from time to time by the Parties; and, initially, the losses shall be
3% of the power and energy to be delivered.

        4.04 Continuity of Service

        The Parties shall use all reasonable care to provide
continuous delivery of electric energy unless they are prevented from
doing so for the following reasons:

a.      Interruptions or reductions due to uncontrollable forces
        which, by exercise of due diligence and foresight, could not
        reasonably have been avoided.  The term "uncontrollable
        forces" shall be deemed to mean any cause beyond the control
        of the Party affected, including, but not limited to, failures
        of facilities, flood, earthquake, storm, fire, lightning,
        epidemic, war, riots, civil disturbance, labor disturbance,
        sabotage, and restraint by court or public authority.  The
        Party rendered unable to fulfill any obligation by reason of
        uncontrollable forces shall exercise due diligence to remove
        such inability with all reasonable dispatch.

b.      Interruptions or reductions due to operation of devices
        installed for electric system protection.

c.      Temporary interruptions or reductions which are necessary or
        desirable for the purposes of maintenance, repairs,
        replacements, installation of equipment, or investigation and
        inspection.  Each Party shall give the other Party reasonable
        advance notice of such interruptions or reductions, except in
        case of an emergency as determined by the Party creating the
        interruption or reduction, and shall remove the cause thereof
        with all reasonable dispatch.


                         ARTICLE V
                          General

        5.01 Liability

        Each Party shall be responsible for its own facilities and
