          Northern States Power Company (Minnesota) and Subsidiaries

                         NOTES TO FINANCIAL STATEMENTS

      In the opinion of management, the accompanying unaudited financial
statements contain all adjustments necessary to present fairly the
financial position of Northern States Power Company (Minnesota) (the
Company) and its subsidiaries (collectively, NSP) as of September 30,
1994 and December 31, 1993, the results of its operations for the three
and nine months ended September 30, 1994 and 1993, and its cash flows
for the nine months ended September 30, 1994 and 1993.  Due to the
seasonality of NSP's electric and gas sales, operating results on a
quarterly basis are not necessarily an appropriate base from which to
project annual results.

      The accounting policies followed by NSP are set forth in Note 1
to NSP's financial statements in the 1993 Form 10-K.  The following
notes should be read in conjunction with such policies and other
disclosures in the Form 10-K.

      Certain reclassifications have been made to 1993 financial
information to conform with the 1994 presentation.  These
reclassifications had no effect on net income or earnings per share as
previously reported.

1.  Accounting Changes

Postemployment Benefits

      Effective January 1, 1994 NSP adopted the provisions of Statement
of Financial Accounting Standards (SFAS) No. 112 - Accounting for
Postemployment Benefits.  This standard required the accrual of certain
postemployment costs (such as injury compensation and severance) that
are payable in future time periods.  The annual expense for costs
accrued under SFAS No. 112 is not materially different than amounts
recognized under NSP's prior accounting method.  NSP has recorded its
full liability related to such costs in 1994 but has deferred the pre-
1994 portion chargeable to operating expense (approximately $9 million)
based on the Company's preliminary decision to request amortization and
rate recovery over future periods, consistent with regulatory precedent
for similar costs.  On October 26, 1994 the Minnesota Public Utilities
Commission (MPUC) approved another Minnesota utility's request to defer
pre-1994 SFAS No. 112 costs and amortize them over a three-year period. 
When the MPUC's order becomes available in the fourth quarter of 1994,
the Company plans to evaluate its cost recovery options for SFAS No. 112
costs, including the possible use of the three-year amortization
procedure approved by the MPUC.

Fair Value Accounting for Certain Investments

      Effective January 1, 1994 NSP adopted the provisions of SFAS No.
115 - Accounting for Certain Investments in Debt and Equity Securities. 
This new standard resulted in an increase of approximately $4.1 million
to decommissioning investments to present such investments at their
market value at September 30, 1994.  This increase represents an
unrealized gain on investments which has been deferred as a regulatory
liability.  The Company anticipates the offsetting of such gains against
decommissioning costs in future ratemaking.

Accounting for Employee Stock Ownership Plans (ESOP)

      Effective January 1, 1994 NSP adopted the American Institute of
Certified Public Accountants' Statement of Position (SOP) 93-6.  This
SOP required the accrual of compensation expense for any market value
increase in uncommitted leveraged ESOP shares. It also required the
reduction of average common shares used to compute earnings per share
by such uncommitted ESOP shares.  No compensation expense was required
to be recorded by NSP upon adoption of the SOP.  The impact of the
reduction in average common shares had an immaterial impact on 1994
earnings per share (less than 1 cent).  Of the 5.4 million shares of the
Company's stock that NSP's ESOP currently holds, an average of
approximately 134,000 uncommitted leveraged ESOP shares were excluded
from earnings per share calculations for the first nine months of 1994. 
The fair value of NSP's leveraged ESOP shares approximated cost at
September 30, 1994.

Stock Compensation Expense

      The Financial Accounting Standards Board (FASB) had previously
issued an Exposure Draft requiring the accrual of compensation expense
related to certain stock awards beginning in 1997, with disclosure
required beginning in 1994.  On June 8, 1994, the FASB postponed issuing
the final version of the proposed new accounting rule, and eliminated
disclosure requirements for 1994.

2.  Non-Regulated Earnings and International Investments

       NSP's net income for the first nine months of 1994 includes
earnings from all non-regulated businesses of $20.9 million, or $0.31
per share.  Through its subsidiaries, NRG Energy, Inc. (NRG), a wholly
owned subsidiary of the Company, has purchased equity interests in
three significant non-regulated international energy projects.  Earnings
from equity interests in these international projects for the first nine
months of 1994 were $15.8 million before income taxes and $12.9 million
net of foreign income taxes, or approximately $0.20 per share.

German Projects

      In December 1993, a subsidiary of NRG agreed to acquire an
ownership interest in the German corporation Mitteldeutsche
Braunkohlengesellschaft mbh (MIBRAG).  MIBRAG was formed by the German
government to operate coal mines, electric power plants, and other
energy related facilities.  NRG's subsidiary and its two investor
partners each agreed to acquire 33% interests in MIBRAG, while the
German government retained a 1% interest.  The investor partners began
operating MIBRAG effective January 1, 1994, subject to several
contingencies.  NSP's earnings for the first quarter of 1994 did not
include NRG's equity in the earnings of MIBRAG due to the unresolved
contingencies.  During the second quarter 1994, essentially all of the
contingencies were favorably resolved.  Accordingly, in June 1994 NRG
recorded its equity in earnings of the MIBRAG project for the first six
months of 1994.  The legal closing occurred on August 11, 1994.  Through
September 30, 1994, NRG had invested approximately $15 million,
including capitalized development costs, for its interest in MIBRAG.

      Through September 30, 1994, another subsidiary of NRG had invested
$10 million, including capitalized development costs, in its 50% interest
in a German corporation, Saale Energie GmbH (Saale).  Saale owns a 400-
megawatt share of a 900-megawatt power plant (Schkopau power station)
currently under construction near Schkopau, Germany.  See Note 4 to the
Financial Statements for further discussion of commitments related to
this project.

Australian Projects

      Through March 1994, another subsidiary of NRG had invested
approximately $70 million, including capitalized development costs, in
a joint venture which acquired a 1680-megawatt coal-fired power plant
in Gladstone, Queensland, Australia.  NRG's investment represents a
37.5% ownership in the Australian plant.

Foreign Currency Transactions

      Local currencies are generally the functional currency of NSP's
foreign operations.  Assets and liabilities of international
subsidiaries are translated at end-of-period rates of exchange.  Income,
expense and cash flows are translated at weighted-average rates of
exchange for the period.  The resulting currency translation adjustments
are accumulated and reported as a separate component of shareholder's
equity.

      Gains and losses that result from translation of foreign currency
transactions (i.e. converting cash into a different currency at a
translation rate different from that which applied when the receivable
or payable was accrued) will be included in the results of operations. 
Through September 30, 1994, NRG had not experienced any material
translation gains or losses from foreign currency transactions which
have occurred since the respective investment dates.

      NRG does not speculate in foreign currencies.  NRG's policy
is to hedge foreign currency denominated investments as they are made
to preserve the U.S. dollar value of its equity position in foreign
currency denominated investment assets.  NRG has entered into hedging
transactions through the use of forward foreign currency exchange
agreements.  Gains and losses on these contracts offset the effect of
foreign currency exchange rate fluctuations on the valuation of the
investments underlying the hedges.  The net effect of these gains and
losses is reported with other currency translation adjustments as a
separate component of stockholders' equity.  NRG is not hedging currency
translation adjustments related to operating results.

       As a part of its hedging program, NRG has entered into three
forward foreign currency exchange contracts with a counterparty. 
Pursuant to these contracts, transactions have been executed which are
designed to protect the economic value of NRG's equity investments that
are denominated in Australian dollars and German deutsche marks (DM). 
Management believes NRG's exposure to credit risk due to nonperformance
by the counterparty to its forward exchange contracts is not significant
based on the Investment Grade credit rating of the counterparty.

      NRG's forward foreign currency exchange contracts hedge
approximately $83 million of foreign currency denominated investments
and $10 million of foreign currency denominated investment commitments
at September 30, 1994.  These forward foreign currency exchange
contracts are not reflected in NSP's balance sheet.  The contracts
terminate in 2004 and require foreign currency interest payments by
either party during each year of the contract.  If the contracts had
been terminated at September 30, 1994, $1.7 million would have been
payable to NRG for currency exchange rate changes to date.

Income Taxes for International Operations

      It is the intention of NSP's management to indefinitely reinvest
the earnings of foreign operations.  Accordingly, U.S. deferred income
taxes and foreign withholding taxes have not been provided on the
earnings of foreign subsidiary companies.  The cumulative amount of
undistributed pretax earnings of foreign subsidiaries upon which no U.S.
deferred income taxes or foreign withholding taxes have been provided
is approximately $15.8 million at September 30, 1994.  The additional
U.S. income tax and foreign withholding tax on the unremitted foreign
earnings, if repatriated, would be offset in whole or in part by foreign
tax credits, and thus it is impracticable to estimate the amount of tax
that might be payable.

U.S. Cogeneration Project

      In July 1994, Michigan Cogeneration Partners Limited Partnership
(MCP), a joint venture between subsidiaries of NRG and Cogentrix Energy,
Inc., reached an agreement with Consumers Power Company (Consumers), an
electric utility headquartered in Jackson, Michigan, to terminate the
power sales contract related to a 65 megawatt cogeneration facility being
developed by MCP in Parchment, Michigan.  The agreement to terminate the
contract required Consumers to make a payment to MCP of $29.8 million.  As
a result, NRG has recorded a net gain from the termination of this contract
which has increased NSP's earnings by approximately nine cents per share in
the third quarter of 1994.  NRG's net gain from the termination in the
third quarter has been partially offset by a write-down of investments in
other domestic energy projects which decreased NSP's earnings by approximately
four cents per share.

3.  Investments Accounted for by the Equity Method

      Project Investments - NSP has investments in various projects
accounted for by the equity method of accounting.  Current investments
include both international and domestic energy projects and domestic
affordable housing and real estate projects.  Prior to 1994 such
investments had been limited to immaterial domestic projects.  The
equity method is applied to investments in which NSP does not have a
majority interest or is not able to exercise a controlling influence
over operating and financial policies.  A summary of the significant
investments is as follows:

                                                  Economic      Placed in

     Summarized Financial Information of Unconsolidated Investees -
Summarized financial information for these projects, including interests
owned by NSP and other parties, was as follows as of September 30, 1994
and for the nine-month period then ended:

Equity                              449.1

Total Liabilities and Equity     $1,800.5

4.  Commitments and Contingent Liabilities

      The Company's public liability for claims resulting from any
nuclear incident, and insurance coverage thereon, have not changed
significantly from the circumstances set forth in Note 15 to the
Company's financial statements contained in the Company's 1993 report
on Form 10-K.

      NRG is contractually committed to additional equity investments
in Saale.  Such commitments are for approximately DM 16.5 million in
1994, DM 36 million in 1995, and DM 35 million in 1996.  The 1994
commitment has been hedged through a forward foreign currency exchange
contract for $10 million.  The 1995 and 1996 commitments would be
approximately $23 million each year, based on exchange rates in effect
at September 30, 1994.

5.  Resolution of Operating Contingency

      The onsite storage pool for spent nuclear fuel at the Company's
Prairie Island Nuclear Generating Plant (Prairie Island) was filled
during refueling in June 1994, so adequate space for a subsequent
refueling is no longer available.  In anticipation of this, the Company
proposed construction of a temporary onsite dry cask storage facility
for spent nuclear fuel at Prairie Island.  The Minnesota Legislature
(Legislature) considered the dry cask storage issue during its 1994
legislative session as required by a Minnesota Court of Appeals ruling
in June 1993.  

      On May 10, 1994, the Governor of the State of Minnesota (Governor)
signed into law a bill passed by the Legislature on May 6, 1994.  The
law authorizes the Company to install 17 dry casks at Prairie Island if
the Company satisfies certain responsibilities.  The Company executed
an agreement with the Governor concerning the renewable energy and
alternative siting commitments contained in the new law and is now
authorized the first increment of five casks.  The second increment of
four casks would be available if the Minnesota Environmental Quality
Board finds that by December 31, 1996, the Company has applied to the
Nuclear Regulatory Commission for an alternative site license for the
temporary spent nuclear fuel storage facility, used good faith in
locating an alternative site and has committed to build or purchase 100
megawatts of wind generation. The final increment of eight casks would
be available unless prior to June 1, 1999, the Legislature specifically
revokes the authorization for the final eight casks.  The Legislature
can revoke the authorization if an alternative storage site is not
operational or under construction, or the Company fails to meet certain
renewable energy commitments, including the increased use of wind power
and biomass generation facilities by December 31, 1998.   

      The Company has taken steps to comply with the new legislative
requirements.  Currently, 25 megawatts (Mw) of wind generation are in
place and all significant permit applications have been filed for
another 100 Mw.  The Company anticipates filing with the MPUC a proposal
for the first 50 Mw of biomass generation later this fall.  In addition,
the Company announced its plan to seek significant public input in its
exploration for an alternative interim spent nuclear fuel storage site
in Goodhue County.  The Company's construction commitments are not
expected to be materially different than levels previously disclosed in
the 1993 Form 10-K as a result of the 1994 Prairie Island legislation. 
The impact of the legislation on power purchase commitments is not yet
determinable.

      An updated nuclear decommissioning study and nuclear plant
depreciation capital recovery request was filed with the MPUC in July
1994 for the Company's nuclear power plants.  Although management
expects to operate the Prairie Island plant units through the end of
their useful lives, the requested capital recovery would allow for the
plant to be fully depreciated, including the accrual and recovery of
decommissioning costs, about six years earlier than the end of its
useful life.  The proposed recovery period has been reduced because of
the uncertainty regarding the spent fuel storage situation.  The study
supports a decrease in cost estimates for decommissioning.  The combined
impact of the request if approved as filed, including the shorter
depreciation period and lower decommissioning costs, would be a decrease
of about $500,000 in annual depreciation and decommissioning expenses. 
Although there is no time deadline for MPUC action, the Company is
hopeful of a decision by the end of the year.

6.  Rate Matters

      NSP's 1993 Annual Report on Form 10-K discussed an appeal filed
by intervenors in the Company's 1993 Minnesota electric and gas rate
cases.  On August 2, 1994,  the Minnesota Court of Appeals affirmed the
final rate orders issued in January 1994 for these rate cases.  This
appeal process is now completed.  As a result of this decision, no
adjustments or changes are required to rates charged to customers or to
revenues recorded by the Company.

      On August 9, 1994 the Company applied to the North Dakota Public
Service Commission (NDPSC) for a rate reduction of $3.6 million in
annual electric revenues.  The reduction reflects a correction in cost
allocations to the North Dakota jurisdiction.  The Company also
requested authority to make refunds to customers to effectively
implement the reduction as of June 1, 1994.  On November 9, 1994, the
NDPSC approved the proposed rate reduction, the liability for which has
been accrued as of September 30, 1994.  In early 1995 the NDPSC will
address the possibility of retroactive refunds for the period January 1,
1989 through June 1, 1994.  Due to the uncertainty surrounding this issue,
no accrued liability has been recorded for retroactive refunds.

      In 1991, the Minnesota legislature passed a law which granted the
MPUC authority to approve a rate adjustment clause for changes in
certain costs (including property taxes, fees and permits) incurred by
Minnesota public utilities.  The MPUC may approve a utility's use of the
rate adjustment clause for billing customers if certain conservation
expenditure levels are met.  On September 30, 1994 and October 4, 1994,
the Company filed for approval of the use of the rate adjustment clause
for billing its electric and gas customers, respectively, beginning in
January 1995.  The potential annual revenue increase from these filings
is approximately $18.4 million.  

Item 2         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATION

Results of Operations

      Northern States Power Company's earnings per share for the third
quarter ended September 30, 1994, were $1.09, up $.13 from the $.96
earned for the same period a year ago.  For the first nine months of
1994, earnings per share were $2.78, up $.51 from the $2.27 earned in
the comparable period a year ago.  The number of average common and
equivalent shares outstanding (considering stock options and awards)
during the third quarter and first nine months of 1994 increased in
comparison to 1993 by approximately 362,000 shares due to the exercise
and granting of stock options and awards, and 2,135,000 shares due
mainly to a general stock offering made in May 1993, respectively.

      In addition to items noted in the 1993 Form 10-K, the historical
and future trends of NSP's operating results have been and are expected
to be impacted by the following factors:

      Non-regulated Businesses - Through September 1994, NSP's non-
regulated businesses have provided a $.25 increase in earnings per share
due mainly to income contributions from various energy projects.  See
Notes 2 and 3 to the Financial Statements for more information on these
projects.

      Prairie Island Nuclear Fuel Storage - In May 1994 the Minnesota
Legislature approved a plan for the temporary onsite storage of spent
nuclear fuel at the Company's Prairie Island Nuclear Generating Plant,
if the Company satisfies certain responsibilities.  See Note 5 to the
Financial Statements for more information on this matter.

      Accounting Changes - Effective January 1, 1994, NSP adopted three
new accounting standards for postemployment benefits, fair value
accounting for certain investments and employee stock ownership plan
transactions.  These accounting changes had an immaterial impact on
earnings in the third quarter of 1994, and are not expected to have a
material impact on the full year 1994.  See Note 1 to the Financial
Statements for more information on these accounting changes.

      Rate Changes - The Company has proposed a $3.6 million annual
reduction in rates charged to electric customers in North Dakota
effective June 1, 1994.  See Note 6 to the Financial Statements for
discussion of this and other potential rate changes.


Third Quarter 1994 Compared with Third Quarter 1993

      Electric revenues for third quarter 1994 compared with third
quarter 1993 increased $13.2 million or 2.4%.  Retail revenues increased
approximately $17.8 million or 3.5% largely due to a 3.0% increase in
electric retail sales and a 0.5% average retail price increase.  The
increase in sales levels is due mainly to sales growth.  The retail
price increase is due to fuel expense recovery.  Revenues from sales to
other utilities decreased by $7.5 million mainly due to a 22.8% sales
decrease.  The sales volume decrease is due to the unusually high sales
in 1993 to utilities affected by flooding.

      Gas revenues for the third quarter 1994 decreased $2.8 million or
6.3% compared with the third quarter of 1993.  Firm gas revenues
decreased $4.9 million or 16.0% due to a 8.9% decrease in gas sales
volume and a 7.7% average retail price decrease.  The sales volume
decrease is due primarily to weather impacts in September.  The price
decrease is due to rate adjustments for decreased purchased gas costs
resulting from changed natural gas supply and demand market conditions. 
Other gas revenues increased $1.7 million due mainly to a new revenue
source, supplying gas to industrial customers not on NSP's system.

      Fuel for electric generation and Purchased and interchange power
combined for a net increase of $5.5 million or 3.6% for the third
quarter of 1994 compared with the third quarter of 1993.  Fuel expense in
the third quarter increased mainly due to higher 1994 generation levels
of fossil fuel plants as a result of a scheduled nuclear plant
maintenance and refueling outage and higher customer energy
requirements in 1994 compared to the same time period in 1993.  These
factors also contributed to an increase in the amount of power purchased
over the same period.  Fuel expenses also increased due to a higher
average cost of nuclear fuel in 1994 compared with 1993 due to full
utilization of nuclear plants in 1993.  These increased fuel and
purchased power expenses were partially offset by lower market pricing of
purchased power in 1994 due to more favorable conditions existing in
third quarter 1994 compared with third quarter 1993.  

      Cost of gas purchased and transported for the third quarter 1994
compared with the third quarter 1993 decreased $9.0 million or 26.4% due
to lower cost per thousand cubic feet (Mcf) of purchased gas, and gas
cost adjustments due to purchased gas adjustment clauses.  The impact
of the cost decrease of lower firm sales volumes was offset by the
impact of supplying gas to industrial customers not on NSP's system.

      Other operation, Maintenance and Administrative and general
expenses together increased $15.3 million or 10.1% compared with the
third quarter 1993.  The higher costs are due mainly to the timing of
expenses rather than a long-term increase in costs.  First, costs
increased by $4.3 million due to a scheduled nuclear plant refueling and
maintenance outage in third quarter 1994 compared with no similar costs
in third quarter 1993.  Also, $3.6 million of tree trimming costs,
delayed from earlier in the year, increased expenses in the third
quarter 1994 compared to the same period a year ago.  Finally,
approximately $4 million of the 1994 expense increase relates to
postretirement health care cost accruals, including amounts deferred
from 1993.

      Depreciation and amortization increased $1.5 million or 2.2%
compared with the third quarter 1993.  The increase is mainly due to
increased plant in service between the two periods.

      Property and general taxes for the third quarter 1994 compared
with the third quarter of 1993 increased $2.0 million or 3.5% due
primarily to higher property tax rates in the State of Minnesota. 
General taxes increased due to higher gross earnings taxes from higher
sales levels in 1994.

      Income taxes for the third quarter 1994 compared with the third
quarter 1993 decreased $3.7 million or 9.0% primarily due to lower
pretax operating income between the two periods.  In addition, income
taxes were higher in third quarter 1993 due to a 1% statutory federal
tax rate increase enacted in August 1993, retroactive to January 1,
1993.

      Equity in earnings of unconsolidated investees increased $6.0
million in the third quarter 1994 compared with the same period a year
ago, due primarily to earnings contributions from NRG's equity in
earnings of international energy projects.

      Other income (expense) - net increased $5.1 million in the third
quarter 1994 compared with the same period a year ago primarily due to
interest income associated with the settlement of an NSP federal income
tax dispute.  This increase was offset in part by foreign income taxes
related to NRG's equity in earnings of international energy projects.

First Nine Months of 1994 Compared with First Nine Months of 1993

      Electric revenues for the nine months of 1994 compared with the
first nine months of 1993 increased $76.0 million or 5.1%.  Retail
revenues increased approximately $78.9 million or 5.8% due to both
higher sales levels and rate increases.  Retail electric sales increased
3.8% in 1994 due to sales growth and more favorable weather in 1994,
while price per unit increased 1.9% due to fuel expense recovery and
recognition of the full impact of Minnesota electric retail rate
increases in 1994.

      Gas revenues increased $13.8 million or 4.8% compared to the first
nine months of 1993.  Firm gas revenues decreased approximately $3.8
million or 1.6% due to a 0.8% decrease in gas sales volumes and an
average price decrease of 0.8%.  Interruptible gas revenues decreased
$0.8 million or 2.2% compared to the first nine months of 1993 due
mainly to lower sales volumes.  Revenues from Viking Gas Transmission
Company, which was acquired in June 1993, increased revenues by $7.3
million.  Other gas revenues increased $10.5 million, mainly due to a
new revenue source, supplying gas to industrial customers not on NSP's
system.

      Fuel for electric generation and Purchased and interchange power
together increased $51.0 million or 13.0% over the nine months ended
September 1993.  The increase was due mainly to higher cost of purchased
power, primarily resulting from increased demand expenses associated
with the new Manitoba Hydro contract effective in May 1993 and increased
market pricing of purchases in 1994 compared to more favorable market
pricing conditions in the first half of 1993.  Also, power purchases
were higher in 1994 than 1993 due to increased customer energy
requirements.  Fuel costs for electric generation increased due to higher
1994 fossil fuel generation levels to meet increased customer energy
requirements and due to scheduled outages of lower cost plants.  

      Cost of gas purchased and transported for the first nine months
of 1994 compared with the first nine months of 1993 decreased $4.2
million or 2.2%.  This is mainly the result of a lower cost of purchased
gas due to market conditions and lower purchased gas cost adjustments,
offset by higher sendout volumes primarily due to supplying gas to
industrial customers not on NSP's system.

      Other operation, Maintenance and Administrative and general
expenses together increased $8.6 million or 1.8%.  The increase is due
entirely to higher postretirement health care costs in 1994, including
amounts which were deferred from 1993.

      Depreciation and amortization increased $6.1 million or 3.1%
compared to the nine months ended September 1993.  The increase is due
primarily to increased plant in service between the two periods.

      Property and general taxes increased $8.4 million or 4.9% compared
with the first nine months of 1993.  The increase is due mainly to
higher property tax rates in the State of Minnesota and also due to
higher gross earnings taxes due to higher sales levels in 1994.

      Income taxes for the first nine months of 1994 compared with the
first nine months of 1993 increased $10.6 million or 10.8%.  The
increase is due primarily to higher pretax operating income between the
two periods.  

      Equity in earnings of unconsolidated investees increased
approximately $18.0 million in the first nine months of 1994 compared
with the same period a year ago, due primarily to earnings contributions
from NRG's international projects.

      Other income (expense) - net increased $7.1 million compared with
the first nine months of 1993 due primarily to interest income
associated with the settlement of an NSP federal income tax dispute. 
In addition, higher income from non-regulated operations was offset by
foreign income taxes related to NRG's equity in earnings of
international energy projects.

      Interest charges before allowance for funds used during
construction have decreased $1.8 million or 2.1% compared with the first
nine months of 1993 due to refinancings, retirements of long-term debt,
and increased use of lower-cost short-term commercial paper borrowings,
partially offset by new debt incurred in connection with businesses
acquired in 1993.

Liquidity and Capital Resources

      The Company had $250.3 million in commercial paper debt
outstanding as of September 30, 1994.  The Company plans to keep credit
lines of at least 85% of the maximum level of commercial paper
borrowings.  Commercial banks currently provide credit lines of
approximately $299 million.  These credit lines make short-term
financing available in the form of bank loans and support for commercial
paper sales.  The Company has regulatory approval for up to $350 million
in short-term borrowing levels.

      Commercial banks currently provide credit lines of $11 million to
wholly owned subsidiaries of the Company.  Approximately $9 million of
those credit lines remained available at September 30, 1994.

      In January 1994, stock options for the purchase of 290,138 shares
were awarded.  As of September 30, 1994, a total of 784,489 stock
options were outstanding, which were considered as potential common
stock equivalents for earnings per share purposes.

      As of September 30, the Company has issued 26,010 new shares of
common stock in 1994.  All of these new shares were issued under the
Executive Long-Term Incentive Award Stock Plan. 

      On February 10, 1994 the Company issued $200,000,000 of first
mortgage bonds due February 1, 1999 with an interest rate of 5 1/2%. 
The proceeds from these bonds were used to redeem $30,000,000 in
principal amount of its 6 1/8% First Mortgage Bonds, due June 1, 1995
at a redemption price of 100.29%, to redeem $45,000,000 in principal
amount of its 5 7/8% First Mortgage Bonds due August 1, 1996 at a
redemption price of 100.51%, to redeem $30,000,000 in principal amount
of its 6 1/2% First Mortgage Bonds due October 1, 1997 at a redemption
price of 100.75%, and to redeem $45,000,000 in principal amount of its
6 3/4% First Mortgage Bonds due May 1, 1998 at a redemption price of
100.93%.  The remaining proceeds were added to the general funds of the
Company and used to repay short-term borrowings. 

      NSP has three interest rate swap agreements covering first
mortgage bonds of approximately $320 million.  These agreements
effectively convert the interest costs of these debt issues from fixed
to variable rates based on short-term interest rates.  Thus, market
risks associated with these agreements result from short-term interest
rate fluctuations.  Credit risk related to nonperformance of the
counterparties is not deemed significant, but would result in NSP
recording interest expense at the stated rate of each bond issue.  While
such agreements are not reflected on NSP's balance sheets, interest rate
swap transactions are recognized as an adjustment of interest expense
over the terms of the agreements. 

      The Company entered into one such interest rate swap agreement
during 1994 with Kidder, Peabody Global Capital Corporation, which
effectively converted the interest cost of the 5 1/2% first mortgage
bonds issued on February 10, 1994 from fixed rate to variable rate.  The
variable rate is set six months in arrears based on a short-term interest
rate indicator with the rate changing on February 1 and August 1 of
each year until final maturity.  Accrued interest expense is recorded
at estimated net interest rates until the actual rate is set.  The net
interest rate charged for the six months ended August 1, 1994 was
approximately 4.6%.  The estimated net interest rate accrued for the
two months ended September 30, 1994 was approximately 5.4%.

      On February 25, 1994 the Company repurchased $10,000,000 of 9 3/8%
First Mortgage Bonds due June 1, 2020 at a price of 112.75%.  On April
12, 1994 the Company repurchased another $20,000,000 of these 9 3/8%
bonds at a price of 110.24%.      

      On May 17, 1994 NSP's wholly owned subsidiary, United Power and
Land (UP&L) issued long-term debt of $10,000,000.  The debt carries an
interest rate of 7.62%, matures in 2000 and is secured by UP&L property. 
Proceeds were used to recapitalize NSP's equity investment in UP&L.

      On October 5, 1994 the Company issued $150,000,000 of first
mortgage bonds due October 1, 2001 with an interest rate of 7 7/8%.  The
proceeds from these bonds were used to repay short-term commercial paper
borrowings which had been increased while the Company was evaluating the
issuance of the bonds during the first nine months of 1994.  The Company
continues to evaluate the early redemption of higher rate securities
and, depending on capital market conditions, may refinance them with
lower rate long-term debt. 

       During the first quarter of 1994, the Company was placed on
"credit watch" by Moody's Investors Service and Duff & Phelps Credit
Rating Co. (D&P) due to the prior uncertainty regarding Prairie Island. 
D&P removed the Company from credit watch on May 9, 1994, following
passage of the law regarding Prairie Island, and reaffirmed the previous
bond ratings.  On May 20, 1994, Moody's Investors Service downgraded the
credit ratings of the Company and Northern States Power Company
(Wisconsin), a wholly owned subsidiary of the Company.  The new ratings
are as follows:  first mortgage bonds and secured pollution control
bonds to A1 from Aa2; shelf registration of senior secured debt to (P)
A1 from (P) Aa2; unsecured pollution control bonds to A2 from Aa3;
preferred stock to "a2" from "aa3"; and shelf registration for preferred
stock to (P) "a2" from (P) "aa3".  The commercial paper rating of the
Company remains unchanged at P-1. 

                          Part II.  OTHER INFORMATION

Item 1.  Legal Proceedings

      On May 27, 1994, the Company was notified by the United States
Environmental Protection Agency (USEPA) that it is a potentially
responsible party (PRP) at the Union Scrap Iron & Metal III Superfund
site in Minneapolis, Minnesota, which is in addition to the sites
identified in NSP's 1993 Annual Report on Form 10-K.  The USEPA states
that total costs incurred to investigate and remediate the site were
approximately $1,000,000.  Over 25 parties have received similar
notifications.  On October 17, 1994, the Company was notified of a
potential settlement between the United States and PRPs.  Under the
proposed settlement the Company would be required to pay $30,000.  If
settlement is not reached, it is likely the USEPA would sue the Company
and other PRPs for recovery of the remediation costs.

      In October 1992, the Company disclosed to the Minnesota Pollution
Control Agency (MPCA), the USEPA and the Nuclear Regulatory Commission
that reports on halogen content of water discharged at Prairie Island
were based on estimates of halogen content rather than actual physical
samples of water discharged as required by the plant's National
Pollution Discharge Elimination System permits.  Even though the water
discharges at the plant did not exceed the halogen levels allowed under
the permits, the applicable state and federal statutes would permit the
imposition of fines, the institution of criminal sanctions and/or
injunctive relief for the reporting violations.  Corrective actions were
taken by the Company.  The Company and the MPCA are currently
negotiating a Stipulation Agreement to address monitoring procedures
used at Prairie Island between January and September 1992 that allegedly
did not comply with the permits.  The MPCA is alleging noncompliance
with permit terms and conditions and is proposing a civil penalty of
$105,436.

any other rule of law limits the time by which ownership interests in

such calculations shall be made in accordance with the purpose and
intent of Sections 2.2.2 and 5.1.6 hereof and the interests of the
Participants in Sherco 3 shall vest in such final percentages no later
than the time limited by such other rule of law or 21 years after the
death of the last survivor of all the persons listed in Exhibit J
hereto, whichever period is applicable.

which is allocable thereto, plus (c) 37.500% of an amount determined by
multiplying the Sherco 3 Site acreage times the average per acre price
of NSP's original cost of acquiring the Sherco Plant Site as it exists
on the date hereof and the Sherco 3 Site; provided, however, that if
NSP's AFUDC annual accrual rate during the period from the effective
date of this Agreement to the date of the SOUTHERN MINNESOTA Closing
exceeds 8% at any time, then the calculation of the payment due from
SOUTHERN MINNESOTA shall be determined as if the AFUDC annual accrual
rate Were limited to 8% for such time; and provided further, that should
SOUTHERN MINNESOTA have commenced paying Cost of Construction prior to
the SOUTHERN MINNESOTA Closing, then there shall be deducted from the
purchase price calculated hereunder the aggregate amount of Cost of
Construction so paid by SOUTHERN MINNESOTA and the amount of AFUDC
included in the calculation of such purchase price shall be
appropriately adjusted to reflect such payments.

         Prior to the SOUTHERN MINNESOTA Closing, NSP shall furnish
SOUTHERN MINNESOTA a statement showing the estimated Cost of
Construction paid and to be paid through the date of the SOUTHERN
MINNESOTA Closing, broken down into major categories and supported by
detail reasonably adequate for the purpose of SOUTHERN MINNESOTA's
review thereof, and shall include, without limiting the generality of
the foregoing, information demonstrating the basis for all allocations
of administrative and general expenses and information demonstrating the
basis for any other allocations of expenses between or among Sherco 3
and the other generating units at the Sherco Plant Site.  Such statement
shall also include a certificate stating that NSP keeps its books in
conformity with the Uniform System of Accounts and that the portion of
such estimated Cost of Construction actually paid is as recorded on the
books of NSP (excluding any recorded amounts which are not included
within the term Cost of Construction) and is attributable to Sherco 3;
provided, however, that such estimated Cost of Construction is subject
to adjustment based upon the actual Cost of Construction paid through
the date of the SOUTHERN MINNESOTA Closing.

         The foregoing purchase price shall be payable to NSP in clearing
house funds.  SOUTHERN MINNESOTA and NSP shall have until the one
hundred eightieth day after the SOUThERN MINNESOTA Closing, after the
UNITED MINNESOTA Closing or after the furnishing to SOUThERN MINNESOTA
of an accounting by NSP of such Cost of Construction, whichever occurs
last, to question or contest the correctness of the purchase price paid
by SOUTHERN MINNESOTA pursuant to this Section after which time the
correctness of such purchase price shall be conclusively presumed.  In
the event of an error in calculation of the purchase price as provided
in this Section, within thirty days NSP shall reimburse SOUTHERN
MINNESOTA or SOUTHERN MINNESOTA shall make payment to NSP, as the case
may be, in the amount charged or failed to be charged in error.  Any
such reimbursement by NSP to SOUTHERN MINNESOTA shall be made in
immediately available funds with Interest calculated from the date of
the SOUTHERN MINNESOTA Closing to the date of reimbursement at NSP's
average current cost of borrowed funds during the period.  Any such
payment by SOUTHERN MINNESOTA to NSP shall be made in immediately
available funds with interest calculated from the date of the SOUTHERN
MINNESOTA Closing to the date of payment at NSP's average current cost
of borrowed funds during the period.

              (c) Subject to the terms and conditions hereof and the
         simultaneous occurrence of the sale and conveyance referred to
         in paragraph (a) of this Section, at the SOUTHERN MINNESOTA
         Closing NSP shall convey to SOUTHERN MINNESOTA an easement in
         any land included in the Sherco Plant Site on which is situated
         any portion of Sherco 3 and such other easements and rights of
         way over land or interests in land included in the Sherco Plant
         Site as shall be necessary to afford to SOUTHERN MINNESOTA the
         full use and enjoyment of Sherco 3.  The easements, rights of
         way and other interests to be conveyed pursuant to the
         foregoing sentence are set forth on Exhibit H hereto.  Such
         easements, rights of way and other interests shall
         automatically terminated upon retirement of Sherco 3.  SOUTHERN
         MINNESOTA shall not be required to make any payment to NSP, at
         the SOUTHERN MINNESOTA Closing or thereafter, in respect of
         such conveyances.  The intent of the Participants is that all
         NSP Common Facilities, other than land, are fixtures and part
         of the real property to which they are attached.  NSP hereby
         grants to SOUTHERN MINNESOTA an easement to use such fixtures
         through the Project Manager for the benefit of Sherco 3. 
         Should it be determined at any time that all or any portion of
         the NSP Common Facilities are personal property as opposed to
         fixtures, then NSP shall lease such NSP Common Facilities to
         SOUTHERN MINNESOTA for a term co-extensive with the term of
         this Agreement.  The consideration for any such lease shall be
         the agreement of SOUTHERN MINNESOTA to perform its obligations
         under this Agreement.  NSP shall furnish to SOUTHERN MINNESOTA
         a properly executed release of Harris Trust and Savings Bank,
         as trustee under NSP's first mortgage indenture, releasing from
         the lien of such indenture any easement, right of way or other
         interest conveyed to SOUTHERN MINNESOTA under this paragraph in
         property owned by NSP.  Such release shall be substantially in
         the form of Exhibit G hereto.

              (d) SOUTHERN MINNESOTA Closing. The closing of the sales
         and conveyances contemplated by paragraphs (a) and (c) of this
         Section (the "SOUTHERN MINNESOTA Closing") will take place on
         the first business day following the 90th day after the
         issuance of the Certificate of Need; provided, however, that if
         all such conditions precedent specified in Section 2.1.3 hereof
         have not been fulfilled by such date, the SOUTHERN MINNESOTA
         Closing shall take place as soon thereafter as SOUTHERN
         MINNESOTA and NSP agree that such conditions precedent have
         been fulfilled.

              (e) Post-Closing Conveyances. From time to time after the
         SOUTHERN MINNESOTA Closing, NSP and SOUTHERN MINNESOTA shall
         execute and deliver such other instruments of conveyance and
         transfer as may be necessary or appropriate or as either party
         may reasonably request to vest in SOUTHERN MINNESOTA the
         undivided ownership interest inn and to Sherco 3 and the other
         interests required to be conveyed pursuant to paragraphs (a)
         and (c) of this Section.

              (f) Evidence of Title. At the SOUTHERN MINNESOTA Closing
         and at such other time or times subsequent thereto as NSP,
         pursuant to paragraph (e) of this Section, shall deliver to
         SOUTHERN MINNESOTA instruments of conveyance and transfer, NSP
         shall also furnish to SOUTHERN MINNESOTA evidence satisfactory
         to SOUTHERN MINNESOTA that NSP is the owner of good and
         marketable title to all property and interests, real and
         personal, to be conveyed to SOUTHERN MINNESOTA, free and clear
         of all mortgages and other liens and encumbrances except those
         permitted by Section 1.2.2(d) hereof.

         hereof.

         SECTION 2.1.4.  Sale to UNITED MINNESOTA.

              (a) Sale of Assets. Subject to the terms and conditions
         hereof and the simultaneous occurrence of the conveyances
         referred to in paragraph (c) of this Section, at the UNITED
         MINNESOTA Closing NSP will sell and convey to UNITED MINNESOTA
         and UNITED MINNESOTA will purchase from NSP a 6.125% undivided
         ownership interest, as a tenant in common with NSP and the
         other Participants, in the Sherco 3 Site and the other
         components of Sherco 3, excluding Joint Common Facilities, to
         the extent acquired or constructed, installed or stored in or
         on the Sherco 3 Site and the Sherco Plant Site prior to the
         UNITED MINNESOTA Closing. In addition, NSP shall convey and
         UNITED MINNESOTA will purchase, as tenant in common with NSP,
         a 5.396% undivided ownership interest in the Joint Common
         Facilities to the extent acquired or constructed, installed or
         stored in or on the Sherco 3 Site and the Sherco Plant Site
         prior to the UNITED MINNESOTA Closing.  The conveyance of the
         Sherco 3 Site will be on a Minnesota Standard Form Warranty
         Deed in substantially the form attached hereto as Exhibit E and
         such other conveyances by Bills of Sale or Assignments of
         Contract Rights in substantially the forms attached hereto as
         Exhibits F and K, respectively.  Such transfers may be subject
         to an option allowing NSP to re-acquire the land for the same
         price by notice to UNITED MINNESOTA within 90 days after the
         retirement of Sherco 3.  At the UNITED MINNESOTA Closing, NSP
         will furnish to UNITED MINNESOTA a properly executed release
         from Harris Trust and Savings Bank, as trustee under NSP's
         first mortgage indenture, releasing from the lien of such
         indenture all property title in which is being conveyed to
         UNITED MINNESOTA hereunder.  Such release shall be
         substantially in the form of Exhibit G hereto.

              (b) Purchase Price and Payment. At the UNITED MINNESOTA
         Closing, UNITED MINNESOTA shall pay to NSP for the property to
         be purchased by it pursuant to paragraph (a) of this Section an
         amount equal to the sum of (a) 5.396% of any Cost of
         Construction paid through the UNITED MINNESOTA Closing for the
         Joint Common Facilities and all AFUDC recorded on the books of
         NSP which is allocable thereto, plus (b) 6.125% of all Cost of
         Construction paid through the UNITED MINNESOTA Closing for the
         balance of the Sherco 3 Project (exclusive of Cost of
         Construction paid by NSP for the Sherco 3 Site) and all AFUDC
         recorded on the books of NSP which is allocable thereto, plus
         (c) 6.125% of an amount determined by multiplying the Sherco 3
         Site acreage times the average per acre price of NSP's original
         cost of acquiring the Sherco Plant Site as it exists on the
         date hereof and the Sherco 3 Site; provided, however, that if
         NSP's AFUDC annual accrual rate during the period from the
         effective date of this Agreement to the date of the UNITED
         MINNESOTA Closing exceeds 8% at any time, then the calculation
         of the payment due from UNITED MINNESOTA shall be determined as
         if the AFUDC annual accrual rate were limited to 8% for such
         time; and provided further, that should UNITED MINNESOTA have
         commenced paying Cost of Construction prior to the UNITED
         MINNESOTA Closing, then there shall be deducted from the
         purchase price calculated hereunder the aggregate amount of
         Cost of Construction so paid by UNITED MINNESOTA and the amount
         of AFUDC included in the calculation of such purchase price
         shall be appropriately adjusted to reflect such payments.

              Prior to the UNITED MINNESOTA Closing, NSP shall furnish
         UNITED MINNESOTA a statement showing the estimated Cost of
         Construction paid and to be paid through the date of the UNITED
         MINNESOTA Closing, broken down into major categories and
         supported by detail reasonably adequate for the purpose of
         UNITED MINNESOTA's review thereof, and shall include, without
         limiting the generality of the foregoing, information
         demonstrating the basis for all allocations of administrative
         and general expenses and information demonstrating the basis
         for any other allocations of expenses between or among Sherco
         3 and the other generating units at the Sherco Plant Site. 
         Such statement shall also include a certificate stating that
         NSP keeps its books in conformity with the Uniform System of
         Accounts and that the portion of such estimated Cost of
         Construction actually paid is as recorded on the books of NSP
         (excluding any recorded amounts which are not included within
         the term Cost of Construction) and is attributable to Sherco 3;
         provided, however, that such estimated Cost of Construction is
         subject to adjustment based upon the actual Cost of
         Construction paid through the date of the UNITED MINNESOTA
         Closing.

              The foregoing purchase price shall be payable to NSP in
         clearing house funds.  UNITED MINNESOTA and NSP shall have
         until the one hundred eightieth day after the SOUTHERN
         MINNESOTA Closing, after the UNITED MINNESOTA Closing or after
         the furnishing to UNITED MINNESOTA of an accounting by NSP of
         such Cost of Construction, whichever occurs last, to question
         or contest the correctness of the purchase price paid by UNITED
         MINNESOTA pursuant to this Section after which time the
         correctness of such purchase price shall be conclusively
         presumed.  In the event of an error in calculation of the
         purchase price as provided in this Section, within thirty days
         NSP shall reimburse UNITED MINNESOTA or UNITED MINNESOTA shall
         make payment to NSP, as the case may be, in the amount charged
         or failed to be charged in error.  Any such reimbursement by
         NSP to UNITED MINNESOTA shall be made in immediately available
         funds with interest calculated from the date of the UNITED
         MINNESOTA Closing to the date of reimbursement at NSP's average
         current cost of borrowed funds during the period.  Any such
         payment by UNITED MINNESOTA to NSP shall be made in immediately
         available funds with interest calculated from the date of the
         UNITED MINNESOTA Closing to the date of payment at NSP's
         average current cost of borrowed funds during the period.

              (c) Subject to the terms and conditions hereof and the
         simultaneous occurrence of the sale and conveyance referred to
         in paragraph (a) of this Section, at the UNITED MINNESOTA
         Closing NSP shall convey to UNITED MINNESOTA an easement in any
         land included in the Sherco Plant Site on which is situated any
         portion of Sherco 3 and such other easements and rights of way
         over land or interests in land included in the Sherco Plant
         Site as shall be necessary to afford to UNITED MINNESOTA the
         full use and enjoyment of Sherco 3.  The easements, rights of
         way and other interests to be conveyed pursuant to the
         foregoing sentence are set forth in Exhibit H hereto.  Such
         easements, rights of way and other interests shall
         automatically terminate upon retirement of Sherco 3.  UNITED
         MINNESOTA shall not be required to make any payment to NSP, at
         the UNITED MINNESOTA Closing or thereafter, in respect of such
         conveyances.  The intent of the ParticipantS is that all NSP
         Common Facilities, other than land, are fixtures and part of
         the real property to which they are attached.  NSP hereby
         grants to UNITED MINNESOTA an easement to use such fixtures
         through the Project Manager for the benefit of Sherco 3. 
         should it be determined at any time that all or any portion of
         the NSP Common Facilities are personal property as opposed to
         fixtures, then NSP shall lease such NSP Common FacilitieS to
         UNITED MINNESOTA for a term co-extensive with the term of this
         Agreement.  The consideration for any such lease shall be the
         agreement of UNITED MINNESOTA to perform its obligations under
         this Agreement. NSP shall furnish to UNITED MINNESOTA a
         properly executed release of Harris Trust and Savings Bank, as
         trustee under NSP's first mortgage indenture, releasing from
         the lien of such indenture any easement, right of way or other
         interest conveyed to UNITED MINNESOTA under this paragraph in
         property owned by NSP.  Such release shall be substantially in
         the form of Exhibit G hereto.

              (d) UNITED MINNESOTA Closing. The closing of the sales and
         conveyances contemplated by paragraphs (a) and (c) of this
         Section (the "UNITED MINNESOTA Closing") will take place on the
         first business day following the 90th day after the issuance of
         the Certificate of Need; provided, however, that if all
         conditions precedent specified in Section 2.1.5 hereof have not
         been fulfilled by such date, the UNITED MINNESOTA Closing shall
         take place as soon thereafter as UNITED MINNESOTA and NSP agree
         that such conditions precedent have been fulfilled.  In no
         event, however, shall UNITED MINNESOTA be obligated to
         consummate the UNITED MINNESOTA Closing until the SOUTHERN
         MINNESOTA Closing has taken place.  If the UNITED MINNESOTA
         Closing is not consummated by July 1, 1983 or the date which is
         six months after the date of the SOUTHERN MINNESOTA Closing,
         whichever is later, then NSP shall not be required to make the
         sales and conveyances to UNITED MINNESOTA referred to in this
         Section 2.1.4.

              (e) Post-Closing Conveyances. From time to time after the
         UNITED MINNESOTA Closing, NSP and UNITED MINNESOTA shall
         execute and deliver such other instruments of conveyance and
         transfer as may be necessary or appropriate or as either party
         may reasonably request to vest in UNITED MINNESOTA the
         undivided ownership interest in and to Sherco 3 and the other
         interests required to be conveyed pursuant to paragraphs (a)
         and (c) of this Section.

              (f) Evidence of Title. At the UNITED MINNESOTA Closing and
         at such other time or times subsequent thereto as NSP, pursuant
         to paragraph (e) of this Section, shall deliver to UNITED
         MINNESOTA instruments of conveyance and transfer, NSP shall
         also furnish to UNITED MINNESOTA evidence satisfactory to
         UNITED MINNESOTA that NSP is the owner of good and marketable
         title to all property, real and personal, to be conveyed to
         UNITED MINNESOTA, free and clear of all mortgages and other
         liens and encumbrances except those permitted by Section
         1.2.2(d) hereof.

         SECTION 2.1.5.  Conditions Precedent to UNITED MINNESOTA

         UNITED MINNESOTA is bound; all requisite governmental,
         regulatory and vendor approvals and consents for the execution
         and delivery by UNITED MINNESOTA of this Agreement and the
         purchase by UNITED MINNESOTA of the property to be purchased by
         it hereunder have been obtained; and this Agreement constitutes
         a valid and binding obligation of UNITED MINNESOTA enforceable
         in accordance with its terms, except as limited by applicable
         bankruptcy, insolvency, reorganization or similar laws at the
         time in effect; and (c) there are no actions, suits or

         (having made diligent inquiry with respect thereto), threatened
         against or affecting UNITED MINNESOTA before any court or
         administrative body or agency which might materially adversely
         affect the ability of UNITED MINNESOTA to perform its
         obligations under this Agreement.

              (b) UNITED MINNESOTA Conditions. The obligation of UNITED
         MINNESOTA to make the purchases from NSP required to be made by
         it pursuant to Section 2.1.4 hereof is subject to the
         fulfillment, prior to or at the UNITED MINNESOTA Closing, of
         each of the following conditions (or the waiver of such
         conditions by UNITED MINNESOTA):

              (i) UNITED MINNESOTA shall not have discovered any material
         error, misstatement or omission in the representations and
         warranties made by NSP in this Agreement.

         the UNITED MINNESOTA Closing provided for herein; and UNITED
         MINNESOTA shall have been furnished with a certificate of the

         Agreement and that (b) to the best of such officer's knowledge,
         there are no defects in the construction of, or other major
         problems or controversies in connection with, Sherco 3 which,

         operation of Sherco 3, or any portion thereof, or materially
         affect the rights or obligations of UNITED MINNESOTA in respect
         of Sherco 3.

              (iii) UNITED MINNESOTA shall have been furnished with an
         opinion of counsel for NSP, dated the date of the UNITED
         MINNESOTA Closing, to the effect that (a) NSP is a corporation

         UNITED MINNESOTA hereunder in the property included in Sherco
         3 which is acquired or constructed, installed or stored in or
         on the Sherco 3 Site and the Sherco Plant Site as of the date
         of the UNITED MINNESOTA Closing, free and clear of all
         mortgages and other liens and encumbrances except easements and
         other rights expressly reserved by NSP in any of the foregoing
         documents; and (e) the instruments delivered to UNITED
         MINNESOTA to convey the easements, rights of way and other
         interests in property required to be conveyed to UNITED
         MINNESOTA at the UNITED MINNESOTA Closing pursuant to paragraph
         (c) of Section 2.1.4 hereof are effective to make the
         conveyances purported to be made, free and clear of all
         mortgages and other liens and encumbrances except that such
         opinion may except any specific easements or encumbrances which
         are permitted by Section 1.2.2(d) hereof.

              (c) Mutual Conditions. The respective obligations of NSP
         and UNITED MINNESOTA pursuant to Section 2.1.4 hereof are
         subject to the fulfillment, prior to or at the UNITED MINNESOTA
         Closing, of the following further conditions (or the waiver
         thereof by NSP and UNITED MINNESOTA):

              (i) SOUTHERN MINNESOTA shall have executed and delivered
         this Agreement.

              (ii) UNITED MINNESOTA shall have entered into a
         transmission agreement with United Power Association, providing
         for the delivery of United Minnesota's Entitlement to its
         members, and an agreement with NSP providing for the
         transmission of UNITED MINNESOTA'S Entitlement through NSP's
         system.

              (iii) All requisite governmental, regulatory and vendor
         approvals and consents for the execution and delivery by NSP
         and UNITED MINNESOTA of this Agreement, the sale and conveyance
         by NSP of the property to be sold by it to UNITED MINNESOTA
         hereunder, and the purchase by UNITED MINNESOTA of such
         property, shall have been obtained.

              (iv) The release of Harris Trust and Savings Bank, as
         trustee under NSP's first mortgage indenture, contemplated by
         Section 2.1.4(a) and (c) hereof shall have been received.

              (v) UNITED MINNESOTA shall have received net proceeds from
         the issuance and sale of its bonds or notes adequate to finance
         the purchase of all property to be purchased by it from NSP at
         UNITED MINNESOTA Closing pursuant to Section 2.1.4 hereof.

              (vi) UNITED MINNESOTA shall have entered into contracts for
         the sale of electric capacity and energy with member
         municipalities having an aggregate peak load in 1980 of 56 MW.

         SECTION 2.1.6.  Payments Prior to Closings.  The Participants
agree that, if the sale of SOUTHERN MINNESOTA's bonds or notes is
delayed so as to cause the SOUTHERN MINNESOTA Closing to be delayed
beyond October 1, 1982, the Participants will meet on that date to
review the Commercial Operation Date provided in Section 3.2.7 and to
approve a budget for Cost of Construction to be incurred after October
1, 1982.  The vote of Participants whose aggregate Ownership Percentages
(assuming the closings hereunder had occurred) equal or exceed 65% shall
be necessary to approve such a budget.  If a budget is approved, each
Participant shall be liable for and pay a share equal to its Joint
Common Facility Percentage of Cost of Construction for Joint Common
Facilities paid by NSP after approval of the budget and a share equal
to its Ownership Percentage of all other Cost of Construction paid by
NSP after approval of the budget; provided, however, that UNITED
MINNESOTA shall not be liable to any other Participant hereunder for
failure to make payments required hereunder if such failure is a result
of its inability to obtain financing necessary therefor.  Payments will
be made to NSP in accordance with Section 3.3.3.  If a budget is not
approved, NSP shall have the right, with no liability to the other
Participants, to terminate this Agreement, in which case the other
Participants shall deliver an appropriate release to NSP confirming such
termination; provided, however, that any termination by NSP must be made
on 60 days prior written notice to the other Participants and that, if
either the SOUTHERN MINNESOTA Closing shall occur or a budget shall be
approved within such 60-day notice period, this Agreement will not
terminate.  If a budget is not approved and NSP does not terminate this
Agreement, NSP may proceed with construction, but with no obligation to
the other Participants to maintain a construction schedule which will
result in Sherco 3 being completed and placed in service by the date
specified in Section 3.2.7 hereof.  However, after the SOUTHERN
MINNESOTA Closing, the Management Committee shall confirm the completion
date or establish a new completion date for purposes of Section 3.2.7
and the provisions of such Section shall again be applicable.

         In the event that the SOUTHERN MINNESOTA Closing occurs, but the
obligation of NSP to make the sale and conveyances to UNITED MINNESOTA
referred to in Section 2.1.4 hereof is discharged, pursuant to Section
2.1.4(d) hereof, because the UNITED MINNESOTA Closing fails to occur by
the date indicated in Section 2.1.4(d), then, as soon as practicable
after such date, NSP shall convey to SOUTHERN MINNESOTA, and SOUTHERN
MINNESOTA shall purchase from NSP, as a tenant in common with NSP, (a)
an additional 2.500% undivided ownership interest in the Sherco 3 Site
and other components of Sherco 3, excluding Joint Common Facilities, and
(b) an additional 1.880% undivided ownership interest in the Joint
Common Facilities, in each case to the extent acquired or constructed,
installed or stored in or on the Sherco 3 Site and the Sherco Plant Site
prior to such conveyance.  Such interests shall be conveyed in the
manner set forth in Section 2.1.2(a) and (c) hereof, free and clear of
all mortgages and other liens and encumbrances except those permitted
by Section 1.2.2(d) hereof, and the purchase price for such interests
shall be calculated on the same basis as the purchase price paid by
SOUTHERN MINNESOTA pursuant to Section 2.1.2 (b) hereof.  The respective
obligations of NSP and SOUTHERN MINNESOTA under this paragraph shall be
subject to satisfaction of the respective conditions specified in
Section 2.1.3 hereof.  From and after the sale and conveyance provided
for in this paragraph, the respective Ownership Percentages and Joint
Common Facility Percentages shall be revised to reflect such sale and
conveyance.

         At any time after SOUTHERN MINNESOTA and UNITED MINNESOTA
commence making payments under this Agreement and through the SOUTHERN
MINNESOTA Closing and UNITED MINNESOTA Closing, respectively, SOUTHERN
MINNESOTA and UNITED MINNESOTA each shall be deemed to own (a) a
percentage undivided interest in the Joint Common Facilities determined
by dividing the amount of Cost of Construction for Joint Common
Facilities paid by it through such time by the total amount of Cost of
Construction for Joint Common Facilities paid by all Participants
through such time and (b) a percentage undivided interest in the balance
of Sherco 3 determined by dividing the amount of Cost of Construction
therefor paid by it through such time by the total amount of Cost of
Construction therefor paid by all Participants through such time.  From
time to time, upon the request of SOUTHERN MINNESOTA or UNITED
MINNESOTA, NSP shall deliver such deeds, bills of sale, certificates and
opinions as shall be requested to evidence such ownership interests of
SOUTHERN MINNESOTA and UNITED MINNESOTA.

         SECTION 2.1.7.  Additions to Sherco Plant Site.  From time to
time after the respective closings hereunder, if it is found that any
land, easements or rights of way not then owned by NSP are necessary to
the full use and enjoyment of Sherco 3, NSP shall either (a) arrange for
the acquisition of such land, easements or rights of way by all
Participants in proportion to their respective Ownership Percentages or
(b) shall acquire such lands, easements or rights of way as part of the
Sherco Plant Site and convey to each of the other Participants such
interests therein as shall be necessary to afford to each other
Participant the full use and enjoyment of Sherco 3. Any such lands,
easements or rights of way acquired as part of the Sherco Plant Site
shall be set forth in a revised Exhibit C hereto.

         SECTION 2.1.8.  "As Is" Sale.  THE RESPECTIVE OWNERSHIP
INTERESTS OF SOUTHERN MINNESOTA AND UNITED MINNESOTA IN ThE PROPERTY
INCLUDED IN SHERCO 3 ARE TO BE SOLD "AS IS" AND "WHERE IS".  NSP MAKES
NO REPRESENTATION OR WARRANTY WHATSOEVER IN THIS AGREEMENT, EXPRESSED,
IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION
OR WARRANTY AS TO THE VALUE, QUANTITY, CONDITION, SALEABILITY,
OBSOLESCENCE, MERCHANTABILITY, FITNESS OR SUITABILITY FOR USE OR WORKING
ORDER OF ANY OF SHERCO 3, NOR DOES NSP REPRESENT OR WARRANT THAT THE USE
OR OPERATION OF SHERCO 3 WILL NOT VIOLATE PATENT, TRADEMARK OR SERVICE
MARK RIGHTS OF ANY THIRD PARTIES.  ThE PROVISIONS OF THIS SECTION 2.1.8
SHALL GOVERN OVER ANY CONFLICTING PROVISIONS OF THIS AGREEMENT.
Notwithstanding the foregoing, SOUTHERN MINNESOTA and UNITED MINNESOTA
shall each be entitled to rely upon any representation or warranty made
by NSP to it in writing either in this Agreement or in any certificate
delivered by NSP to it in connection with its purchase from NSP of an
undivided interest in Sherco 3, and SOUTHERN MINNESOTA and UNITED
MINNESOTA shall each have the benefit, in proportion to its percentage
ownership interest in the property included in Sherco 3, of all
manufacturers and vendors warranties and all patent, trademark and
service mark rights running to NSP in connection with the property
included in Sherco 3; provided that NSP shall have sole authority in
decisions regarding the enforcement (including any renegotiation and
settlement) of such warranties and patent, trademark and service mark
rights.

         ARTICLE 2.2.  COMMON FACILITIES; ADDITIONAL UNITS ON SHERCO
PLANT SITE.

         SECTION 2.2.1.  Mutual Rights.  Without any consideration beyond
the respective obligations of this Agreement, NSP hereby covenants that
the other Participants, through the Project Manager, may use the Common
Facilities owned by it for the use and benefit of Unit 3 and the other
Participants hereby covenant that NSP may use their respective ownership
interest in Common Facilities for the use and benefit of Unit 3 as well
as for the use and benefit of the existing generating units on the
Sherco Plant Site.  Notwithstanding the foregoing, NSP expressly
reserves the right to the full use and benefit of the Sherco Plant Site
and NSP Common Facilities, without any accounting to thee other
Participants, provided that NSP will not subject the Sherco Plant Site
or NSP Common Facilities to any use which unreasonably interferes with
the construction or operation of Sherco 3.

         SECTION 2.2.2.  Calculation of Joint Common Facility
Percentages.

              (a) Objective - In consideration of the exchange of mutual
         rights set forth in Section 2.2.1, the Participants agree that
         the total value of NSP Common Facilities to Sherco 3 shall be
         the sum of the "allocable portion" (as heretofore agreed upon
         by the Participants in accordance with the next sentence) of
         the total investment in each such Facility (including
         investment in such Facilities as they exist on the date hereof
         and investment to be made in NSP Common Facilities
         Modifications) and that the total value of Joint Common
         Facilities to Sherco 3 shall be the sum of the "allocable
         portion" (as heretofore agreed upon by the Participants in
         accordance with the next sentence) of the total investment in
         each such Facility (including in the calculation of investment
         all items which would constitute Cost of Construction
         hereunder).  The "allocable portion" of the investment in each
         NSP Common Facility and in each Joint Common Facility has been
         determined based upon the estimated amount of benefit to be
         derived by Unit 3 from such Facility relative to the estimated
         amount of benefit to be. derived from such Facility by each
         other generating unit or units benefiting from such Facility. 
         The Participants other than NSP will pay their respective
         Ownership Percentage of the total value placed on the
         "allocable portion" of NSP Common Facilities toward the Cost of
         Construction of Joint Common Facilities at those costs accrue
         in the Construction Account.  Accordingly, each Participant
         other than NSP, in lieu of paying to NSP its Ownership
         Percentage of the "allocable portion" of NSP's investment in
         NSP Common Facilities made prior to the closing of its
         acquisition hereunder or paying any portion of the investment
         to be made in NSP Common.Facilities thereafter, will pay a
         percentage of the "allocable portion" of Cost of Construction
         of Joint Common Facilities which is greater than its Ownership
         Percentage and NSP will pay a percentage of the "allocable
         portion" of such Cost of Construction which is less than its
         Ownership Percentage. In addition, as the owner of any other
         generating unit or units which will benefit from each Joint
         Common Facility, NSP will make all other investment (that is,
         the portion not allocable to Sherco 3) required to be made in
         each such Facility.  NSP will make all required investment in
         NSP Common Facilities including, without limitation, all
         investment in NSP Common Facilities Modifications.

              It is the objective of the Participants that each
         Participant's percentage responsibility for the total
         investment in Joint Common Facilities, represented by its Joint
         Common Facility Percentage, be established so that, upon
         completion of construction, the "allocable portion" of such
         Participant's investment in NSP Common Facilities (if any) and
         in Joint Common Facilities will equal its Ownership Percentage
         times the "allocable portion" of the total investment in such
         Common Facilities.  The level of investment required to be made
         by each Participant in Joint Common Facilities to meet this
         objective (its "Objective Investment") shall be determined by
         the formula set forth in paragraph (b) below.  The resulting
         Joint Common Facility Percentage shall be determined in
         accordance with paragraph (c) below.

              (b) Objective Investment Calculation. The Objective
         Investment of each Participant in Joint Common Facilities shall
         be determined by the following formula:

         OI =  OP (Cj-Cx+Ce+Cm)+Cxp-Cep-Cmo
              ---
              100


Where:

         OI   Such Participant's Objective Investment in Joint Common
              Facilities, as to be determined by the formula;

         OP   Such Participant's Ownership Percentage;

         Cj   Total investment in Joint Common Facilities;

         Cx   Total investment in Joint Common Facilities to the extent
              allocable to generating units other than Sherco 3.  The
              Participants have agreed that Cx equals 0.262 times Cj;

         Ce   Total investment in NSP Common Facilities, exclusive of
              investment in NSP Common Facilities Modifications, to the
              extent allocable to Sherco 3. The Participants have agreed
              that Ce equals $6,258,500;

         Cm   Total investment in NSP Common Facilities Modifications to
              the extent allocable to Sherco 3. The Participants have
              agreed that Cm shall equal the sum of (i) 0.866 times the
              total investment in NSP Common Facilities Modifications
              identified in Exhibit B-1 hereto plus (ii) the total
              investment, to the extent allocable to Sherco 3 in
              accordance with Section 2.2.6 hereof, in other NSP Common
              Facilities Modifications from time to time determined to
              be made prior to the completion of construction pursuant
              to Section 2.2.6 hereof;

         Cxp  Such Participant's investment, if any, in Joint Common
              Facilities to the extent allocable to generating units
              other than Sherco 3; solely for purposes of the formula,
              Cxp for NSP shall equal Cx and Cxp for each other
              Participant shall equal zero;

         Cep  Such Participant's investment, if any, in NSP Common
              Facilities, exclusive of investment in NSP Common
              Facilities Modifications, to the extent allocable to Sherco
              3; Cep for NSP shall equal Ce and Cep for each other
              Participant shall equal zero; and

         Cmo  Such Participant's objective investment, if any, in NSP
              Common Facilities Modifications to the extent allocable to
              Sherco 3; solely for purposes of the formula, Cmo for NSP
              shall equal Cm and Cmo for each other Participant shall
              equal zero.

              (c) Joint Common Facility Percentage Calculation.  Subject
         to the provisions of (d) below regarding defaults, the Joint
         Common Facility Percentage of each Participant shall be
         determined by the following formula:

         JP = OI x 100
              --
              Cj

Where:

         JP   Such Participant's Joint Common Facility Percentage as to
              be determined by the formula;

         OI   Such Participant's Objective Investment in Joint Common
              Facilities, as determined under (b) above; and

         Cj   Total investment in Joint Common Facilities.

              (d) Preliminary Calculation and Adjustment.  The
         Participants recognize that the Objective Investment and Joint
         Common Facility Percentage of each Participant cannot be
         finally established until the actual total investment in Joint
         Common Facilities and in NSP Common Facilities Modifications is
         known upon completion of construction. The Joint Common
         Facility Percentages of the respective Participants set forth
         in Exhibit B-2 hereto, therefore, are preliminary in that such
         Percentages (and the Objective Investments on which they are
         based) were calculated under the formulae in (b) and (c) above
         using the cost estimates of Joint Common Facilities and the
         cost estimates of NSP Common Facilities Modifications. 
         Accordingly, not more than 90 days after completion of
         construction, which such completion of construction, for
         purposes of this Agreement, shall occur no later than two years
         after the Commercial Operation Date unless a later date is
         agreed to by SOUTHERN MINNESOTA, the Management Committee shall
         re-calculate the Objective Investment of each Participant under
         the formula in (b) above using the actual total investment in
         Joint Common Facilities and the actual total investment in
         NSP Common Facilities Modifications.

              After the Objective Investment of each Participant has been
         re-calculated as provided above, any Participant whose "Pro
         Forma Investment" in Joint Common Facilities is less than its
         Objective Investment shall pay to the Participant or
         Participants whose "Pro Forma Investment" therein is larger
         than its Objective Investment such amount as is necessary so
         that; each Participant's "Pro Forma Investment" in Joint Common
         Facilities will equal its Objective Investment.  Each
         Participant's "Pro Forma Investment" in Joint Common Facilities
         is defined to mean its actual investment therein (hereinafter
         referred to as the amount Cjp), less any amount included in
         such actual investment attributable to payments made by such
         Participant to cover uncured defaults of other Participants in
         making investment in Joint Common Facilities, plus the amount
         of any uncured defaults by such Participant in making
         investment in Joint Common Facilities.  Following such
         payments, which shall be considered to be adjustments to
         investments in Joint Common Facilities, the Management
         Committee shall re-calculate the Joint Common Facility
         Percentage of each Participant.  If no defaults exist toward
         Cost of Construction of Sherco 3, the Management Committee
         shall re-calculate the Joint Common Facility Percentage of each
         Participant under the formula in (c) above, using such
         Participant's Objective Investment determined under the formula
         in (b) above. However, if one or more Participants are in
         default in the payment of Cost of Construction of Sherco 3, the
         Management Committee shall, in lieu of using the formula in (c)
         above, re-calculate the Ownership Percentage and the Joint
         Common Facility Percentage of each Participant in accordance
         with the provisions of Section 5.1.6 hereunder.  The re-
         calculation of the Joint Common Facility Percentage of each
         Participant made under the formula in (c) above shall be made
         after giving effect to the reclassification as Joint Common
         Facilities, pursuant to Section 2.2.5 hereof, of those NSP
         Common Facilities listed as "Essential Equipment" on Exhibit B-
         1.  The Joint Common Facility Percentages as so finally
         established shall be set forth in an amendment to Exhibit B-2
         hereof.

              Any Participant whose Joint Common Facility Percentage as
         so finally established under this Section 2.2.2 is less than
         that originally set forth in Exhibit B-2 hereof (i) shall
         deliver to each other Participant or Participants whose final
         Joint Common Facility Percentage is greater than that
         originally set forth in Exhibit B-2 such deeds, bills of sale,
         certificates and opinions as such other Participant shall
         request to evidence such interest and

              (ii) shall take such action as shall be necessary so that
         much interest shall be owned by such other Participant free and
         clear of any mortgages and other liens and encumbrances except
         those permitted by Section 1.2.2(d) hereof.

         SECTION 2.2.3.  Future Common Facilities.  Upon acquisition,
construction or installation of any Future Common Facilities, the
Management Committee shall determine the Sherco 3 Portion thereof, and
such Common Facilities and the Sherco 3 Portion thereof shall be set
forth on Exhibit B-3 hereto.

         SECTION 2.2.4.  Additional Units on Sherco Plant Site.  NSP
shall have the right to (a) install, enlarge, modify and operate any
additional generating unit or units, including necessary appurtenances
thereto, on the Sherco Plant Site, and (b) enlarge, modify and operate
any existing generating unit or units (other than Unit 3), including
necessary appurtenances thereto, on the Sherco Plant Site; provided that
such additional or existing unit or units shall not be so installed,
enlarged, modified or operated as to unreasonably interfere with or
burden the construction or operation of Sherco 3. In the event that NSP
determines to exercise any of its rights under the preceding sentence,
NSP shall also have the right (subject to any approval of the Management
Committee required under Section 3.2.3 hereof) to use, enlarge, modify
or relocate any facilities installed as a part of Sherco 3 in connection
with the installation, enlargement, modification or operation of such
additional or existing unit or units; provided that (a) such use,
enlargement, modification or relocation of Sherco 3 facilities shall not
unreasonably interfere with or burden the construction or operation of
Sherco 3; (b) if such use, enlargement, modification or relocation is
of Sherco 3 facilities which are to be jointly used by Unit 3 and such
additional or existing unit or units, then (i) if said Sherco 3
facilities are then listed as Joint Common Facilities on Exhibit B-2
hereto, but the proposed use by Unit 3 of said Sherco 3 facilities is
different from that previously contemplated, then the obligations of the
Participants with respect thereto shall be determined by the Management
Committee, (ii) if said Sherco 3 facilities are then listed as Future
Common Facilities in Exhibit B-3 hereto, but the proposed Sherco 3
Portion of said Sherco 3 facilities is different from that stated for
said facilities in such Exhibit, then such Exhibit shall be amended
accordingly, or (iii) if said Sherco 3 facilities are not then listed
in Exhibit B-1, B-2 or B-3 hereto, then Exhibit B-3 shall be amended so
as to reflect said Sherco 3 facilities as Future Common Facilities and
the proposed Sherco 3 Portion thereof; (c) the cost of such enlargement,
modification or relocation of Sherco 3 facilities shall not be
considered Cost of Construction hereunder except to the extent that it
results in additions to the Joint Common Facilities or the Sherco 3
Portion of Future Common Facilities; and (d) any net benefits and
savings resulting from the joint use of Sherco 3 facilities by Unit 3
and such additional or existing unit or units, if and when such joint
use occurs, shall be allocated fairly among Unit 3 and such additional
or existing unit or units, and the portion of such net benefits and
savings which is allocated to Unit 3 shall be shared by the Participants
in proportion to their respective Joint Common Facility Percentages, in
cases involving Joint Common Facilities, or their respective Ownership
Percentages, in cases involving Future Common Facilities.

         SECTION 2.2.5.  Transfer of Certain NSP Common Facilities.  At
the time of re-calculating the Joint Common Facility Percentages under
Section 2.2.2(d) or Section 5.1.6 hereof, the facilities listed as
"Essential Equipment" on Exhibit B-1 shall be reclassified as Joint
Common Facilities and Exhibits B-1 and B-2 shall be amended accordingly. 
NSP's original cost of such facilities shall be considered an investment
in Joint Common Facilities and credited to NSP under the appropriate
formulae for re-calculating the Joint Common Facility Percentages. 
After re-calculation of the Joint Common Facility Percentages (giving
effect to the reclassification provided for in this Section), NSP shall
convey to each other Participant an undivided ownership interest in such
facilities equal to its re-calculated Joint Common Facility Percentage. 
NSP shall deliver to each other Participant such deeds, bills of sale,
certificates and opinions as such other Participant shall request to
evidence the conveyances provided for in this Section 2.2.5 and shall
also furnish to each other Participant a properly executed release from
Harris Trust and Savings Bank, as trustee under NSP's first mortgage
indenture, releasing from the lien of such indenture the interests
conveyed and take such action as shall be necessary so that the interest
conveyed shall be owned by such other Participant free and clear of any
mortgages and other liens and encumbrances, except those permitted by
Section 1.2.2(d) hereof.

         SECTION 2.2.6.  Additional NSP Common Facilities Modifications. 
The Participants recognize that it may be necessary, during the period
of construction of Sherco 3, to make certain investments in NSP Common
Facilities in addition to the investment in the NSP Common Facilities
Modifications identified in Exhibit B-1 hereto on the date hereof.  All
such investments shall be made by NSP.  To the extent that such
investments are for repairs and renewals necessary to maintain NSP
Common Facilities in good operating condition, such investments shall
not be considered to be for NSP Common Facilities Modifications and
shall not be reflected in the various formulae contained in Sections
2.2.2 and 5.1.6 hereof.  To the extent that such investments are
determined by the Management Committee to be for modifications which are
necessary as a result of the construction of Sherco 3, such investments
shall be considered to be for NSP Common Facilities Modifications and
such modifications shall be identified as such in an amendment to
Exhibit B-1 hereto. The Management Committee shall determine the portion
of each such investment allocable to Sherco 3 based upon the estimated
amount of benefit to be derived by Unit 3 from each such NSP Common
Facilities Modification relative to the estimated amount of benefit to
be derived from such NSP Common Facilities Modification by each other
generating unit or units benefiting therefrom.  The portion of such
investment so allocable to Sherco 3 shall be reflected in the various
formulae contained in Sections 2.2.2 and 5.1.6 hereof.

         ARTICLE 2.3.  ALIENATION OF INTERESTS

         SECTION 2.3.1.  Special Nature of Sherco 3.

              (a) The Participants recognize that Sherco 3 will be an
         integral part of the facilities required to provide adequate
         service in their respective service territories and that the
         physical partition of Sherco 3 or any material part thereof
         would be impossible and impractical and wholly inconsistent
         with the purposes for which this Agreement is made. 
         Accordingly, and in recognition of these circumstances, the
         Participants agree as provided in the remaining Sections of
         this Article 2.3.

              (b) NSP covenants not to convey any portion of the Sherco
         Plant Site which is needed for Sherco 3 unless the necessary
         rights for Sherco 3 are excepted and reserved from the
         conveyance.

              (c) As used in this Article 2.3, (i) the term "selling
         Participant" means any Participant which hereafter desires to
         dispose of (whether by sale, conveyance, transfer, assignment,
         lease or otherwise) all or any portion of its ownership
         interest in Sherco 3 to the other Participants or any third
         party and (ii) the term "third party" means any entity other
         than one of the Participants.

         SECTION 2.3.2.  Transfers to Third Parties

              (a) If a Participant shall desire to dispose (whether by
         sale, conveyance, transfer, assignment, lease or otherwise) of
         all or any portion of its undivided ownership interest in
         Sherco 3 to any third party or parties, such Participant shall
         give the other Participants written notice thereof, and any
         such transaction with a third party or parties shall not be
         consummated until each of the other Participants has determined
         not to exercise its right of first refusal, as set forth in
         this paragraph.  Such written notice shall fully disclose the
         nature and terms of the proposed transaction and the identity
         of the third party or parties involved, and attach a copy of
         the third party's written offer.  Upon receipt of such written
         notice, the other Participants shall have the first right to
         acquire the entire (but not less than the entire) undivided
         ownership interest in Sherco 3 proposed to be disposed of upon
         the same terms and conditions which the selling Participant
         proposes to make with the third party or parties.  Within 90
         days following receipt of such notice, each other Participant:
         shall give written notice to the selling Participant stating
         whether or not it elects to acquire such undivided ownership
         interest.  If only one Participant elects to do so, then such
         Participant shall acquire such ownership interest.  If more
         than one Participant elects to do so then such Participants
         shall acquire such undivided ownership interest in such
         proportions as they may have agreed upon in writing or, in the
         absence of much agreement, each of such Participants shall
         acquire such ownership interest in proportion to the ratio
         which its undivided ownership interest in Sherco 3 bears to the
         undivided ownership interests in Sherco 3 of all such
         Participants which elect to acquire such undivided ownership
         interest.  The selling Participant, as soon as practicable,
         shall execute such instruments as may be necessary and
         appropriate to effectuate any sale, conveyance, transfer,
         assignment, lease or other disposition pursuant to this Section
         2.3.2, free and clear of all mortgages and other liens and
         encumbrances for which the selling Participant is responsible.

              (b) If none of the other Participants elect to acquire the
         undivided ownership interest in Sherco 3 proposed to be
         disposed of, the selling Participant may consummate its
         proposed transaction with the third party or parties and
         dispose of such ownership interest to the third party or
         parties; provided, however, that such transaction must be
         consummated within one year following the date on which the
         other Participants give written notice to the selling
         Participant pursuant to paragraph (a) of this Section that none
         of them elects to acquire such undivided ownership interest;
         and provided further, that the selling Participant shall
         require (as a condition of or in connection with the sale,
         conveyance, transfer, assignment, lease or other disposition,
         and for the benefit of the other Participants) the third party
         or parties acquiring such undivided ownership interest to
         assume and agree to be bound by the provisions of this
         Agreement and any amendments hereof, and in furtherance thereof
         the provisions of this Agreement shall be amended appropriately
         to reflect (i) the addition of such third party or parties as
         a party or parties to this Agreement, (ii) the ownership
         interest in Sherco 3 acquired by such third party or parties
         and the decreased ownership interest in Sherco 3 of the selling
         Participant and (iii) the rights, duties and obligations of the
         selling Participant and such third party or parties under this
         Agreement.  Further, the selling Participant shall save the
         other Participants harmless from and against all loss or
         liability which they may incur within ten years of the date of
         such disposition as a result of any failure by such third party
         or parties to fulfill its or their duties and obligations under
         this Agreement and any amendments hereof.  In addition, the
         consummation of any transaction by the selling Participant with
         a third party or parties shall not release the selling
         Participant from any of its debts or liabilities to the other
         Participants which, at the time of the consummation of the
         transaction, have accrued under this Agreement, and any
         amendments hereof unless the Participants shall agree in
         writing to the contrary.

              (c) The right of any Participant to dispose of an undivided
         ownership interest to a third party or parties, as set forth in
         paragraph (b) of this Section, is subject to the further
         condition that (i) if such Participant shall undertake to
         consummate its proposed transaction at a time subsequent to one
         year following the date on which the other Participants give
         written notice to the selling Participant pursuant to paragraph
         (a) of this Section that none of them elects to acquire such
         undivided ownership interest or (ii) if such Participant shall
         undertake to dispose of such ownership interest to a third
         party or parties other than those whose identity was disclosed
         in the notice given by the selling Participant to the other
         Participants pursuant to paragraph (a) of this Section, or
         (iii) if such Participant shall undertake to dispose of such
         ownership interest upon different terms and conditions than
         were disclosed in said notice, then the other Participants
         shall be given written notice thereof and shall have the
         further right of first refusal, to the same extent and by the
         same procedure described in paragraph (a) of this Section, with
         respect to any of such proposed transactions.

              (d) The provisions of the foregoing paragraphs (a), (b) and
         (c) of this Section shall continue for the duration of this
         Agreement and shall be applicable to each and every occasion
         and whenever any Participant desires to dispose (whether by
         sale, conveyance, transfer, assignment, lease or otherwise) of
         all or any portion of its ownership interest in Sherco 3 to any
         third party or parties; provided, that such provisions shall
         not be applicable to, and each of the Participants hereby
         consents to, the following:

              (i) the transfer by NSP to Lake Superior District Power
         Company, a Wisconsin corporation ("LSDPC"), of a 2.5% undivided
         ownership interest in Sherco 3, provided that LSDPC shall by
         written agreement assume the obligations of a Participant
         hereunder; or

              (ii) the transfer, assignment, pledge, hypothecation,
         mortgage or grant (by indenture of mortgage, deed of trust or
         otherwise) by any Participant of its undivided interest in
         Sherco 3, together with all or substantially all of its other
         electric utility property, for the purpose of securing bonds or
         other obligations for borrowed money issued or to be issued by
         it, including the effect of any after acquired property clause
         of any such indenture of mortgage, deed of trust or other
         instrument now existing or hereafter created.by such
         Participant, or the realization on or enforcement off such
         security or the exercise by the trustee or the mortgagee, as
         the case may be, or the beneficiaries of such security of any
         of the rights, powers, or privileges provided for with respect
         thereto; or

              (iii) the transferring by any Participant to a third party
         of its undivided ownership interest in Sherco 3, together with
         all or substantially all of its other electric utility
         property, whether by sale or pursuant to or as a result of a
         merger, consolidation or corporate reorganization; provided,
         that such third party, by written agreement or by operation of
         law, assumes the obligations of this Agreement, and any
         amendments hereof of the Participant so transferring; or

              (iv) the transfer, assignment, pledge, hypothecation,
         mortgage or grant by any Participant of its undivided interest
         in pollution control facilities; or

              (v) the transfer, assignment, pledge, hypothecation,
         mortgage or grant by any Participant of its undivided interest
         in fossil fuel at Unit 3 in connection with any financial
         arrangement for the discharge of fossil fuel payment
         obligations.

         SECTION 2.3.3.  Transfer to Another Participant.  Each of the
Participants retains complete freedom to dispose of all or any portion
of its ownership interest in Sherco 3 to any other Participant.  Such
disposition (whether by sale, conveyance, transfer, assignment, lease
or otherwise) shall be made upon such terms and conditions as may be
agreed upon by the selling Participant and such purchasing Participant;
provided, that nothing in the arrangements made by the selling
Participant and such purchasing Participant in regard to such
disposition of ownership interest shall be prejudicial to the rights of
the other Participants under this Agreement.  Further, in the event of
any such transfer of ownership interest by the selling Participant to
any other Participant, this Agreement shall be appropriately amended to
reflect the effect of the decrease in undivided ownership interest of
the selling Participant on the rights, duties and obligations of the
selling Participant and the other Participants under this Agreement.

         SECTION 2.3.4.  Waiver of Right of Partition.  Each of the
Participants agrees that it will not take any action, by judicial
proceedings or otherwise, to partition Sherco 3, nor any part thereof,
in any way, whether by partition in kind or by sale and division of the
proceeds thereof.  Each of the Participants further waives the right of
partition and the benefit of all statutory or common law provisions that
may now or hereafter authorize such partition of Sherco 3 or any part
thereof.  In the event any such right of partition shall hereafter
accrue, each Participant shall from time to time upon the written
request of any other Participant execute and deliver such further
instruments as may be necessary to confirm the foregoing waiver and
release of its right to partition.  The foregoing provisions of this
Section 2.3.4 shall be binding upon and inure to the benefit of the
Participants, their respective successors and assigns, including
mortgagees, receivers, trustees or other representatives and their
respective successors and assigns, and shall run with the land.

         SECTION 2.3.5.  Duration of Limitations.  Each provision of
Section 2.3.2, 2.3.3 and 2.3.4 of this Article 2.3 shall be effective
to the full extent permitted by law, now or hereafter applicable, for
the duration of this Agreement; provided, however, that if the rule
against perpetuities, or any other rule of law, limits the time during
which any such provision can be effective, then such provisions shall
continue to be effective for no longer than the time limited by such
other rule of law or 21 years after the death of the last survivor of
all of the persons listed in Exhibit J hereto, whichever period is
applicable.

         SECTION 2.3.6.  NSP to Remain as Project Manager.  No sale,
lease, conveyance, transfer, assignment or alienation whatsoever by NSP
of any or all of its undivided ownership interest in Sherco 3, whether
as security for an indebtedness, in connection with the financing of
pollution control facilities, or otherwise, shall relieve NSP of its
obligation to act as Project Manager hereunder.

         SECTION 2.3.7.  Interest Transferred Remains Subject to
Adjustment.  The Ownership Percentage and Joint Common Facility
Percentage applicable to any interest disposed of pursuant to this
Article 2.3 shall be subject to adjustment as provided in Sections 2.2.2
and 5.1.6 hereof or any other adjustment provided herein.

         Participants as required hereby, the Participants hereby
         establish a Management Committee.

              (b) The Management Committee shall be composed of one
         primary representative of each Participant and one alternate
         for such primary representative, each to be designated by the
         Participant represented by written notice to the other
         Participants.

         SECTION 3.1.2.  Authority and Responsibility

              (a) The Management Committee shall have such authority,
         responsibility, functions, and duties as are specifically
         assigned to it in this Agreement.

              (b) The Management Committee shall meet on call of any
         Participant and at such other times as may be established by
         the Management Committee.  The Management Committee may
         establish procedures to govern the conduct of its affairs;
         provided, however, that decisions with respect to any matters
         to be decided by the Management Committee pursuant to this
         Agreement shall require the affirmative vote of representatives
         of Participants having Ownership Percentages aggregating not
         less than 65%, such vote to be made in accordance with Section
         5.6.11 hereof.  Decisions made by the Management Committee
         shall be binding upon all Participants except as provided in
         Section 5.4.5 hereof with respect to settlement of disputes.

              (c) The Management Committee may establish such
         subcommittees as it shall deem appropriate.  Each subcommittee
         shall have such responsibilities as shall be delegated to it by
         the Management Committee.  Each subcommittee shall be composed
         of one representative of each Participant, to be designated by
         written notice to the other Participants. Each such
         representative may, but need not, be a member of the Management
         Committee.  Any decision or determination by any subcommittee
         shall be by unanimous vote; if agreement cannot be reached with

         written summary minutes of all meetings.

              (e) Any cost or expense incurred by any Management
         Committee member, or members of any other committee or sub-
         committee created pursuant to this Agreement in connection with
         duties as a member of any committee or subcommittee, shall be
         borne and paid by the Participant the member represents.

              (f) The existence of the Management Committee or any other
         committee or subcommittee created pursuant to this Agreement
         shall not limit or diminish in any manner the authority of the
         Project Manager pursuant to this Agreement, except to the
         extent as may be herein specifically provided.

              (g) The Participants recognize that certain commitments to
         financial participation and the awarding of contracts must be
         confirmed by April 1, 1982 to maintain the Sherco 3 Project's
         schedule.  The Management Committee will meet on or about April
         1, 1982 to confirm the decision to proceed with these actions. 
         The vote of the Management Committee shall be made as if the
         closings hereunder had occurred.

         ARTICLE 3.2.  PROJECT MANAGER

         SECTION 3.2.1.  Appointment.  SOUTHERN MINNESOTA and UNITED
MINNESOTA hereby appoint NSP as their agent (the "Project Manager") in
connection with Sherco 3 to act on their behalf in the planning, design,
licensing, acquisition, construction, completion, management, control,
operation, maintenance, renewal, addition, replacement, modification and
disposal thereof.  NSP hereby accepts such appointment, and in
consideration of the limitations of liability provided herein agrees to
perform its services as Project Manager, charging to the Sherco 3
Project its direct and indirect costs incurred in its capacity as
Project Manager, which may be withdrawn by the Project Manager from the
Construction Account, the Capital Account or the Operating Account, as
appropriate.

         SECTION 3.2.2.  Mutual Dependency

              (a) The Participants recognize that over the term of this
         Agreement, the Project Manager, in the accomplishment of the
         Sherco 3 Project, will find it desirable to procure large
         quantities of goods and services by contract from a large
         number of organizations and individuals, to provide substantial
         resources and personnel, and to recruit and build a substantial
         staff to carry on the Sherco 3 Project.

              (b) The Participants recognize also that unnecessary delays
         in licensing, design and construction could add significantly
         to:the cost of the Sherco 3 Project.  The Participants have
         agreed that the Project Manager should be authorized to act
         promptly and decisively with respect to matters entrusted to it
         hereunder, and accordingly, to the extent provided herein, have
         provided the Project Manager with authority in matters
         pertaining to the accomplishment of the Sherco 3 Project.

         SECTION 3.2.3.  Authority and Responsibility.  Subject to the
authority granted to the Management Committee hereunder, the Project

licensing, design, construction, acquisition, completions management,
control, operation, maintenance, renewal, addition, replacement,
modification and disposal of Sherco 3 and shall take all actions
necessary in discharging such responsibility in accordance with the
applicable provisions of this Agreement.  In respect thereof, and
subject to the applicable provisions of this Agreement, the Project
Manager is authorized, in the name and on behalf of the Participants,
to take all reasonable actions which, in the discretion and judgment of
the Project Manager, are deemed necessary or advisable to effect the
planning, licensing, design, construction, acquisition, completion,
management, control, operation, maintenance, renewal, addition,
replacement, modification and disposal of Sherco 3, including, without
limitation, the following:

              (a) The making of such agreements and modifications of
         existing agreements, other than this Agreement, and the taking
         of such other action as the Project Manager deems necessary or
         appropriate or as may be required under the regulations or
         directives of any regulatory agencies having jurisdiction, with
         respect to the planning, licensing, design, construction,
         acquisition, completion, management, control, operation and
         maintenance of Sherco 3 for commercial operation;

              (b) The making of such agreements and modifications of
         existing agreements, other than this Agreement, after the
         Commercial Operation Date and the taking of such other action
         after the Commercial Operation Date with respect to the
         renewal, addition, replacement or modification of Sherco 3
         (including the Common Facilities) as (i) shall be required
         under the regulations or directives of any regulatory agencies
         having jurisdiction or (ii) the Project Manager shall deem
         necessary or appropriate; provided, however, that except with
         respect to any such agreements or modifications or other
         actions within clause (i) above, any such agreement or
         modification or other action shall be approved by the
         Management Committee unless it involves expenditures of less
         than $2,000,000 and either is necessary to keep Sherco 3 in
         good operating condition in accordance with Prudent Utility
         Practice or is made or undertaken in connection with another
         generating unit on the Sherco Plant Site pursuant to Article
         2.2 hereof;

              (c) The making of such agreements and modifications of
         existing agreements, other than this Agreement, and the taking
         of such other action with respect to the disposal (including
         retirement and salvaging) of all or any part of Sherco 3,
         whether before or after the Commercial Operation Date, as (i)
         shall be required under the regulations or directives of any
         regulatory agencies having jurisdiction or (ii) the Project
         Manager shall deem necessary or appropriate; provided, however,
         that the Management Committee shall approve disposals,
         retirements, and salvage in excess of $2,000,000;

              (d) The execution and filing, with any regulatory agency
         having jurisdiction, of applications, amendments, reports and
         other documents and filings in or in connection with the
         licensing and other regulatory matters with respect to Sherco
         3 except as otherwise provided in Section 3.2.3(h) hereof;

              (e) Subject to the foregoing provisions of this Section
         3.2.3, the right, on behalf of the Participants, to provide, or
         contract with any of its affiliates to purchase or provide, at
         cost, any equipment or facilities or to perform, or contract
         with any of its affiliates to perform, services, at cost, in
         connection with the planning, licensing, design, construction,
         acquisition, completion, management, control, operation,
         maintenance, renewal, addition, replacement, modification and
         disposal of Sherco 3; and

              (f) The settlement of any claims by or against the
         Participants involving third parties relating to the planning,
         licensing, design, construction, acquisition, completion,
         management, control, operation, maintenance, renewal, addition,
         replacement, modification and disposal of Sherco 3; provided,
         however, that the approval of the Management Committee shall be
         obtained for settlement of any such claim by the Participants
         unless the amount originally claimed is less than $2,000,000
         and for settlement of any such claim against the Participants
         unless it would subject the Participants to a total liability
         of less than $2,000,000.

              (g) Any contracts entered into pursuant to this Section
         3.2.3 shall be executed by the Project Manager as agent on
         behalf of the Participants.  If the other party to any contract
         is unwilling to enter into the contract on such basis, the
         Project Manager may enter into such contract on its own behalf
         only but shall hold such contract as agent for the
         Participants.  Contracts entered into by the Project Manager or
         its agent on behalf of the Participants will provide for
         several but not joint liability in proportion to such
         Participants' respective Ownership Percentages unless the other
         party to the contract is unwilling to provide for several
         liability in the contract.  Whether or not a contract specifies
         that it is entered into on behalf of the Participants or
         includes a provision for several liability, the Participants
         agree that, as among themselves, they shall be severally and
         not jointly responsible for their respective Ownership
         Percentages of all amounts payable under or with respect to
         such contract.  The Project Manager is hereby authorized to
         enforce all Sherco 3 contracts which it enters into pursuant to
         this Agreement and all warranties on goods and services sold or
         furnished for Sherco 3 pursuant thereto, in the name of the
         Project Manager, acting as agent for all the Participants;
         provided, however, that each other Participant may enforce any
         such contract and warranties on its own behalf.

              (h) The Project Manager shall have the responsibility to
         execute and file, with all regulatory agencies having
         jurisdiction, such applications, amendments, reports and other
         documents and filings as shall be required in or in connection
         with the licensing and other regulatory matters with respect to
         Sherco 3; provided, however, that each Participant shall have
         the responsibility for proving its need for its undivided
         ownership interest in Sherco 3 in obtaining a Certificate of
         Need, and each Participant shall be responsible for obtaining
         all required approvals and authorizations relating to its
         participation in Sherco 3 and to its performance of this
         Agreement.  The Project Manager and each Participant shall use
         its best efforts to fulfill its responsibilities under this
         Section on a timely basis.

         SECTION 3.2.4.  Consultation.

              (a) The Project Manager hereunder, in addition to obtaining
         the approvals of the Management Committee with respect to
         certain matters as required by this Agreement, shall from time
         to time advise and consult with the Management Committee
         concerning all significant matters with respect to planning,
         licensing, staffing, design, acquisition, construction,
         completion, management, control, operation, maintenance,
         renewal, addition, replacement, modification and disposal of
         Sherco 3 (including plans, specifications, engineering studies,
         construction schedules, environmental reports, budgets and
         supporting data, whether existing on the date hereof or
         hereafter prepared).

              (b) The Project Manager shall timely furnish or make
         available to the Management Committee all records, contracts,
         and other documents relating to Sherco 3, and shall give due
         consideration to comments and recommendations made by each
         Participant; provided, however, that such comments and
         recommendations shall not be allowed to delay Sherco 3 or to
         affect the discretion of the Project Manager acting within the
         scope of its authority.

              (c) Each Participant shall provide to the extent possible
         all assistance requested by the Project Manager and such
         Participant shall be reimbursed for its costs and expenses
         incurred in providing such assistance on such terms and
         conditions as may be agreed upon by such Participant and the
         Project Manager.

         SECTION 3.2.5.  Existing Contracts.  The Participants hereby
ratify and confirm all contracts heretofore entered into by NSP in
connection with and relating to Sherco 3 and each assumes several
liability therefor in proportion to its Ownership Percentage; all such
contracts are described in Exhibit K attached hereto.

         SECTION 3.2.6.  Standards of Conduct.  In accepting
responsibilities, as set forth herein, the Project Manager agrees it
will carry out the provisions of this Agreement with the same prudence
and care that it would exercise if it were constructing and operating
the Sherco 3 Project solely for its own benefit; the Project Manager
further agrees that it will proceed with construction and operation in
accordance with Prudent Utility Practice and other provisions of this
Agreement.

         SECTION 3.2.7.  Commercial Operation Date.  Subject to causes
beyond the reasonable control of the Project Manager, including, without
limiting the generality of the foregoing, accidents, strikes,
litigation, acts of God, the timely receipt of all necessary regulatory
approvals, authorizations and permits, or the procurement of the
necessary rights-of-ways, materials and labor, the Project Manager shall
make its best effort to complete and place in service the Sherco 3
Project on or before May 1, 1986, or such other date as the Participants
may establish by mutual agreement.  If any of the aforesaid causes delay
the installation of the Sherco 3 Project beyond said date, it shall
nevertheless be completed as soon thereafter as reasonably possible.

         SECTION 3.2.8.  Commercial Operation Date Delay.  The Commercial
Operation Date shall be delayed if the Management Committee determines
it benefits the Participants as a group and each Participant has
sufficient power or can purchase sufficient power to meet its needs. 
If any Participant demonstrates a financial loss due to the delay, the
benefiting Participant(s) shall pay the Participant(s) suffering the
loss an amount equal to the loss.  Each benefiting Participant shall
share the loss payment in proportion to its benefit; provided, however,
that if UNITED MINNESOTA is a benefiting Participant it shall not be
required to share the loss payment in an amount which exceeds the amount
of the benefit derived by it. The benefits and losses of Participants
will be determined by the Management Committee.

         SECTION 3.2.9.  Liability.  The liability of the Project Manager
in carrying out the provisions of this Agreement shall be governed by
Article 5.5 hereof.

         SECTION 3.2.10.  Removal of NSP as Project Manager. 
Participants having Ownership PercentageS aggregating not less than 42%
may remove NSP as Project Manager for one or more of the following
reasons:

              (a) NSP's gross negligence or intentional wrongdoing (as
         such terms are defined in Article 5.5 hereof);

              (b) consistent or significant breaches of its obligations
         under this Agreement to the other Participants which are not
         remedied to their satisfaction through the action of the
         Management Committee.

The participants taking such action shall provide all Participants with
a written notice of the decision to remove NSP as Project Manager, which
notice shall identify the date upon which such removal and appointment
shall be effective, the cause for such removal and the provisions hereof
upon which such removal is based.  The removal will not be effective
unless accepted by written notice to the other ParticipantS by NSP
within ten days of the date of the notice.  If NSP does not accept its
removal, it shall continue as Project Manager until final judgment of
a court having jurisdiction that the ParticipantS who have given the
written notice specified above are entitled under this Section to remove
NSP as Project Manager.  The Management Committee, including NSP, shall
select the successor Project Manager.  Costs of the successor Project
Manager shall be paid by all Participants in proportion to their
respective Ownership percentages.  NSP agrees that it will cooperate
with the successor project Manager in facilitating the assumption of
such position by the successor Project Manager and in generally
familiarizing the successor Project Manager and its employees and agents
with Sherco 3.

         ARTICLE 3.3.  BUDGETS, ACCOUNTS AND PAYMENTS

         SECTION 3.3.1.  Construction Budget.  As Project Manager for the
Participants in the construction of Sherco 3, NSP has delivered to the
other Participants an initial construction budget setting forth the
amounts estimated to be expended by the Participants for the Cost of
Construction for Unit 3 and Joint Common Facilities and a summary cash
flow setting forth the amounts estimated to be expended in each quarter
to the estimated Commercial Operation Date of Sherco 3.  By October 1
of each year until the Commercial Operation Date of Sherco 3, the
Project Manager shall provide to all Participants a proposed revised
construction budget supported by detail adequate for the purpose of each
Participant's review thereof, which estimate shall include, without
limiting the generality of the foregoing, information demonstrating the
basis for all allocations of administrative and general expenses,
staffing allocations and the Project Manager services and information
demonstrating the basis for any other allocations of expenses between
or among Sherco 3 and the other units at the Sherco Plant Site, and
which shall describe the items of Cost of Construction and the amounts
expected to be expended therefor each month during the twelve-month
period commencing on the following January 1 and in each quarter
thereafter to the estimated Commercial Operation Date of Sherco 3.  Each
such proposed budget shall include the schedule for Sherco 3 containing
a critical path analysis for the design and construction thereof, a plan
and timetable for obtaining the necessary permits, licenses and
approvals from any agency having jurisdiction over Sherco 3, the then
currently expected Commercial Operation Date of Sherco 3 and such other
plans, timetables or schedules, if any, as the Project Manager may deem
appropriate.  The Management Committee shall then proceed, with due
consideration of comments and recommendations of all Participants, to
adopt a construction budget by January 1 of each year, and, in the
failure of which, the construction budget to be utilized shall be the
one submitted by the Project Manager.  The Project Manager may otherwise
from time to time propose changes in the construction budget or revised
construction budget as necessary to reflect changes in construction
schedules, payment schedules, plans, specifications or costs.  The
Project Manager shall similarly submit such proposed changes to all
Participants and the Management Committee shall approve or disapprove
in accordance with the preceding provisions of this Section 3.3.1.

         The Project Manager shall attempt to construct Sherco 3 in
accordance with the then current construction budget.  The Project
Manager makes no representation, warranty or promise of any kind as to
the accuracy of any such construction budget or that such attempt to
construct Sherco 3 in accordance with the then current construction
budget will be successful.

         In the event the Project Manager alters any construction
schedule or construction budget solely because NSP desires to defer the
time or times at which NSP would otherwise be obligated to contribute
to the Cost of Construction, unless approved by the Management Committee
all Participants shall be liable for construction payments as if such
alteration had not been made.

         The Project Manager shall provide each Management Committee
representative monthly reports which reflect actual construction
expenditures to date, contracts awarded during the past month, and other
developments which may affect the projected construction schedules,
activities, cost estimates and expenditure forecasts.

         SECTION 3.3.2.  Construction Account.  Immediately following the
SOUTHERN MINNESOTA Closing or the UNITED MINNESOTA Closing, whichever
is the first to occur, or at such earlier time as either SOUTHERN
MINNESOTA or UNITED MINNESOTA or both commence making payments in
respect of Cost of Construction, the Management Committee shall direct
the Project Manager to establish for Sherco 3 a separate account or
accounts (the "Construction Account"), which in the discretion of the
Project Manager may be interest bearing or non-interest bearing, in a
bank or banks which insure deposits, subject to applicable limits, with
the Federal Deposit Insurance Corporation.  The Construction Account
shall be held in the names of all of the Participants.  All moneys for
the payment of the Cost of Construction paid following the respective
closings hereunder and prior to the Commercial Operation Date of Sherco
3 shall be deposited by the Participants in the Construction Account and
the Project Manager as agent shall withdraw and apply funds therefrom
only as necessary to pay such Cost of Construction.  At the time the
Management Committee establishes the Construction Account, the Committee
shall determine, based upon the budget, the amounts, if any, that each
Participant shall deposit in the Account immediately and from time to
time thereafter so that the Project Manager shall have sufficient funds
to pay all Costs of Construction which may become payable before regular
deposits to the Account are made in accordance with Section 3.3.3.  In
the event that during any month the balance in the Construction Account
is insufficient to pay the Cost of Construction required to be paid that
month (other than as a result of the nonpayment by a Participant of an
amount due from it pursuant to Section 3.3.3 hereof), the Project
Manager shall promptly so notify the Participants by telephone of the
amount required to be paid by each Participant and thereafter promptly
confirm the same in writing.  Each of the Participants shall pay its
respective share of such deficit into the Construction Account in
immediately available funds not later than on the third banking day
after receipt of such notice from the Project Manager.  The Project
Manager shall have no responsibility or liability to make up any such
deficiency out of its own funds.

         Through the closing of the Construction Account pursuant to the
next paragraph each Participant shall continue to own and maintain its
proportionate undivided ownership interest in the Construction Account
(other than amounts, if any, deposited in the Construction Account
pursuant to the second paragraph of Section 3.3.3 below, which amounts
shall be owned solely by the Participants to whom such amounts are to
be distributed as provided in such paragraph); provided, however, that
the Project Manager shall have the sole right and authority to make
withdrawals from the Construction Account; and provided further, that
a Participant shall not own any undivided ownership interest in any
amount in the Construction Account in respect of interest paid into such
Account by or on behalf of such Participant pursuant to the provisions
of this Agreement, which amount shall, if there is only one other
Participant, be owned entirely by such other Participant and credited
against payments required to be made into such Account by such other
Participant in the performance of its obligations under this Agreement,
and which amount shall, if there are three or more Participants, be
owned in common by, and credit.ed against payments required to be made
into such Account by, the other Participants not then in default in the
performance of their obligations under this Agreement in the proportion
which their respective Joint Common Facility Percentages bear to the
aggregate of their Joint Common Facility Percentages (in the case of
payments relating to the Cost of Construction incurred for Joint Common
Facilities) or in the proportion which their respective Ownership
Percentages bear to the aggregate of their Ownership Percentages (in the
case of payments relating to all other Cost of Construction).  In no
event shall the Project Manager commingle any funds deposited in the
Construction Account with any other funds.

         Upon the completion of construction of Sherco 3, and the
settlement of all the obligations relating to the Cost of Construction
incurred prior to completion, the Project Manager shall close the
Construction Account and distribute to each Participant its undivided
ownership interest of any balance remaining in the Construction Account
(exclusive of amounts therein, if any, in which such Participant shall
not own any undivided ownership interest), except that if a Participant
shall then be in default with respect to any payments required to be
made under this Agreement, an amount equal to the liability of such
defaulting Participant on account of such default (or if such amount
exceeds such Participant's share of the balance in the Construction
Account, its entire share of such balance) shall first be distributed
to the nondefaulting Participant or, if there is more than one
nondefaulting Participant, to the nondefaulting Participants in the
proportion which their respective Joint Common Facility Percentages bear
to the aggregate of their Joint Common Facility Percentages (in the case
of defaults relating to Cost of Construction for Joint Common
Facilities) or in the proportion which their respective Ownership
Percentages bear to the aggregate of their Ownership Percentages (in the
case of defaults relating to all other Cost of Construction).

         SECTION 3.3.3.  Construction Payments.  From and after the
closing of its purchase of an undivided interest in Sherco 3, each
Participant shall pay a percentage share of the Cost of Construction
paid by the Project Manager after such date.  In the case of Cost of
Construction relating to Joint Common Facilities, such percentage share
shall equal its Joint Common Facility Percentage; in the case of all
other Cost of Construction, such percentage share shall equal its
Ownership Percentage.  On or before the twentieth day of each month
following the respective closings, the Project Manager shall:notify each
Participant of the nature and amount of the Cost of Construction
anticipated to be paid during the succeeding calendar month plus or
minus any adjustments for such costs incurred in prior months but not
previously charged or credited to the Participants, as appropriate. 
Each Participant shall make payment into the Construction Account in
immediately available funds of its percentage share of such Cost of
Construction during such succeeding calendar month in accordance with
the schedule determined and delivered to it by the Project Manager;
provided, however, that each Participant shall have not less than three
banking days notice prior to the due date for any requested payment. 
Each such notification by the Project Manager of anticipated costs and
adjustments shall be accompanied and adjusted by an accounting of costs
incurred, as adjusted, for preceding months.

         Each Participant shall have until the one hundred eightieth day
after (i) the date of completion of construction of Sherco 3 or (ii) the
furnishing of an accounting by the Project Manager of all items of the
Cost of Construction paid prior to such date, whichever is later, to
question or contest the correctness of any such charge or credit made
to it pursuant to this Section 3.3.3 in respect of Sherco 3, after which
time the correctness of such charge or credit shall be conclusively
presumed.  In the event that any Participant by timely notice questions
or contests the correctness of any such charge or credit as provided in
the preceding sentence, the Project Manager shall promptly review the
questioned charge or credit and shall within 55 days following such
notice from a Participant notify each Participant of the amount of any
error and the amount of reimbursement, if any, that each Participant is
required to make or is entitled to receive in respect of such error. 
Not later than the third banking day after receipt of such notice from
the Project Manager, each Participant required to make reimbursement
shall deposit the amount specified in such notice into the Construction
Account in immediately available funds.  From the amount so deposited,
the Project Manager shall immediately thereafter distribute in
immediately available funds to each Participant entitled to receive such
reimbursement the amount that such Participant is entitled to receive
(or if the amount so deposited is insufficient to reimburse in Bull all
Participants entitled to receive reimbursement, then the Project Manager
shall distribute the amount so deposited among the Participants entitled
to receive such reimbursement pro rata in accordance with each
Participant's entitlement to reimbursement in respect of such error),
except that if any such Participant is then in default in respect of any
payments required to be made under this Agreement, an amount equal to
such defaulting Participant's share of the amount so deposited with
respect to such reimbursement shall be retained in the Construction
Account and distributed in accordance with the provisions of Section
3.3.2 of this Agreement.

         The Project Manager shall have no responsibility or liability
for the failure of any Participant to deposit funds as provided in this
Section 3.3.3.

         The Project Manager shall provide each Participant with such
information as is reasonably required by such Participant in order to
account for payments made pursuant to this Section 3.3.3 on such
Participant's books.

         SECTION 3.3.4.  Capital Budget.  At least three months prior to
the expected Commercial Operation Date of Sherco 3, the Project Manager,
as agent for the Participants, shall propose to all Participants a
capital budget setting forth the amounts estimated to be expended for
completions, renewals, additions, replacements, modifications and
disposals in connection with Sherco 3 following such date and during
each month from such date through the end of the next full calendar year
and during each year in the four year period commencing on the following
January 1.  Payments shall be made in accordance with the provisions of
Section 3.3.6 hereof.  Each Participant shall be responsible for payment
of (1) its Ownership Percentage of all Cost of Construction contained
in the capital budget relating to Unit 3; (2) its Joint Common Facility
Percentage of all such Cost of Construction relating to Joint Common
Facilities; and (3) its Ownership Percentage of all such Cost of
Construction relating to the Sherco 3 Portion of Future Common
Facilities.  By October 1 of each year thereafter, the Project Manager
shall provide to all Participants a proposed revised capital budget
describing the items of additional Cost of Construction and the amounts
expected to be expended therefor in each month during the twelve-month
period commencing on the following January 1 and during each of the next
three calendar years in respect of such completions, renewals,
additions, replacements modifications and disposals in connection with
Sherco 3.  Each such proposed capital budget and revised capital budget
shall be supported by detail reasonably adequate for the purpose of each
Participant's reasonable review thereof and shall include, without
limiting the generality of the foregoing, information demonstrating the
basis for all allocations of administrative and general expenses and
information demonstrating the basis for any other allocations of expense
between or among Sherco 3 and other generating units at the Sherco Plant
Site.  The Management Committee shall then proceed, with due
consideration of comments and recommendations of all Participants, to
adopt a capital budget by January 1 of each year, and, in the failure
of which the capital budget to be utilized shall be the one submitted
by the Project Manager.  The Project Manager may otherwise from time to
time propose changes in the capital budget and revised capital budget
as necessary to reflect any changes in construction, purchasing or
payment schedules, plans, specifications or costs related to
completions, renewals, additions, replacements, modifications and
disposals in connection with Sherco 3.  The Project Manager shall
similarly submit such proposed changes to all Participants and the
Management Committee shall approve or disapprove them in accordance with
the preceding provisions of this Section 3.3.4.

         The Project Manager shall attempt to make all such completions,
renewals, additions, replacements, modifications and disposals in
connection with Sherco 3 in accordance with the then current capital
budget.  The Project. Manager makes no representation, warranty or
promise of any kind as to the accuracy of any such capital budget or
that such attempt to make all such completions, renewals, additions,
replacements, modifications and disposals in accordance with the then
current capital budget will be successful.

         SECTION 3.3.5.  Capital Account.  Prior to the Commercial
Operation Date of Sherco 3, the Management Committee shall direct the
Project Manager to establish for Sherco 3 a separate account (the
"Capital Account"), which in the discretion of the Project Manager may
be interest bearing or non-interest bearing, in a bank or banks which
insure deposits, subject to applicable limits, with the Federal Deposit
Insurance Corporation.  The Capital Account shall be held in the names
of all of the Participants.  All such payments (for which provision is
made in Section 3.3.6 hereof) of additional Cost of Construction paid
by the Participants after the Commercial Operation Date of Sherco 3
shall be deposited by the Participants in the Capital Account and the
Project Manager as agent shall withdraw and apply funds therefrom only
as necessary to pay such additional Cost of Construction in accordance
with the provisions of Section 3.3.6 hereof.  In the event that during
any month the balance in the Capital Account is insufficient to pay such
additional Cost of Construction required to be paid that month (other
than as a result of the non-payment by a Participant of an amount due
from it pursuant to Section 3.3.6 hereof), the Project Manager shall
promptly so notify the Participants by telephone of the amount required
to be paid by each Participant and thereafter promptly confirm the same
in writing.  Each of the Participants shall pay its respective share of
such deficit into the Capital Account in immediately available funds not
later than on the third banking day after receipt of such notice from
the Project Manager.  The Project Manager shall have no responsibility
or liability to make up any such deficit out of its own funds.

         Until termination of this Agreement and settlement of all
obligations relating to Cost of Construction, each Participant shall
continue to own and maintain its undivided ownership interest in the
Capital Account (other than amounts, if any, deposited in the Capital
Account pursuant to the second paragraph of Section 3.3.6 below, which
amounts shall be owned solely by the Participants to whom such amounts
are to be distributed as provided in such paragraph); provided, however,
that the Project Manager as agent shall have the sole right and
authority to make withdrawals from the Capital Account; and provided
further, that a Participant shall not own any undivided ownership
interest in any amount in the Capital Account in respect of interest
paid into such Account by or on behalf of such Participant pursuant to
the provisions of this Agreement, which amount shall, if there is only
one other Participant, be owned entirely by such other Participant and
credited against payments required to be made into such Account by such
other Participant in the performance of its obligations under this
Agreement, and which amount shall, if there are three or more
Participants, be owned in common by, and credited against payments
required to be made into such Account by, the other Participants not
then in default in the performance of their obligations under this
Agreement in the proportion which their respective Ownership Percentages
bear to the aggregate of their Ownership Percentages (or, in the case
of any payment for Cost of Construction for Joint Common Facilities, in
the proportion which their respective Joint Common Facility Percentages
bear to the aggregate of their Joint Common Facility Percentages).  In
no event shall the Project Manager commingle any funds deposited in the
Capital Account with any other funds.

         Upon termination of this Agreement and settlement of all
obligations relating to Cost of Construction, including without
limitation all costs incurred in the disposal of Sherco 3, the Project
Manager shall close the Capital Account and distribute to each
Participant its undivided ownership interest of any balance remaining
in the Capital Account (exclusive of amounts therein, if any, in which
such Participant shall not own any undivided ownership interest), except
that if a Participant shall then be in default with respect to any
payment required to be made under this Agreement, an amount equal to the
liability of such defaulting Participant on account of such default (or
if such amount exceeds such Participant's share of the balance in the
Capital Account, its entire share of such balance) shall first be
distributed to the nondefaulting Participant or, if there is more than
one nondefaulting Participant, to the nondefaulting Participants in the
proportion which their respective Ownership Percentages bear to the
aggregate of their Ownership Percentages (or, in the case of defaults
relating to Cost of Construction for Joint Common Facilities, in the
proportion which their respective Joint Common Facility Percentages bear
to the aggregate of their Joint Common Facility Percentages).

         SECTION 3.3.6.  Capital Payments.  As agent for the
Participants, the Project Manager will, on or about the twentieth day
of each month, commencing with the month immediately preceding the
Commercial Operation Date of Sherco 3, notify the Participants of the
nature and amount of all additional Cost of Construction anticipated to
be paid during the succeeding calendar month in respect of completions,
renewals, additions, replacements, modifications or disposals of Sherco
3, plus or minus any adjustments for costs paid in prior months but not
previously charged or credited to the Participants under the provisions
of this Section 3.3.6 or Section 3.3.3 hereof. The Project Manager will
give each Participant as much notice as is reasonably practicable of any
major anticipated cost.  Each Participant shall make payment into the
Capital Account in immediately available funds of its applicable
percentage share (determined as provided in Section 3.3.4) of such
additional Cost of Construction during the succeeding month in
accordance with the schedule determined and delivered to it by the
Project Manager; provided, however, that each Participant shall have not
less than three banking days notice prior to the due date of any
requested payment.  Each such notification made by the Project Manager
of anticipated costs and adjustments shall be accompanied and adjusted
by an accounting of costs incurred and credits, if any, received for
preceding months.

         Each Participant shall have until the one hundred eightieth day
after the furnishing of such accounting by the Project Manager for any
charge or credit made to it pursuant to this Section 3.3.6 to question
or contest the correctness of such charge or credit after which time the
correctness of such charge or credit shall be conclusively presumed. 
In the event that any Participant by timely notice questions or contests
the correctness of any such charge or credit, the Project Manager shall
promptly review the questioned charge or credit and shall within 55 days
following such notice from a Participant notify each Participant of the
amount of any error and the amount of reimbursement, if any, that each
Participant is required to make or is entitled to receive in respect of
such error. Not later than the third banking day after receipt of such
notice from the Project Manager, each Participant required to make
reimbursement shall deposit the amount specified in such notice into the
capital Account in immediately available funds.  From the amount so
deposited, the Project Manager shall immediately thereafter distribute
in immediately available funds to each Participant entitled to receive
such reimbursement the amount that such Participant is entitled to
receive (or if the amount so deposited is insufficient to reimburse in
full all Participants entitled to receive reimbursement, then the
Project Manager shall distribute the amount so deposited among the
Participants entitled to receive such reimbursement pro rata in
accordance with each Participant's entitlement to reimbursement in
respect of such error), except that if any such Participant is then in
default in respect of any payments required to be made under this
Agreement, an amount equal to such defaulting Participant's share of the
amount so deposited with respect to such reimbursement shall be retained
in the Capital Account and distributed in accordance with the provisions
of Section 3.3.5 of this Agreement.  The Project Manager shall have no
responsibility or liability for the failure of any Participant to
deposit funds as provided in this Section 3.3.6.

         The Project Manager will provide each Participant with such
information as is reasonably required by such Participant in order to
account for payments made pursuant to this Section 3.3.6 on such
Participant's books.

         SECTION 3.3.7.  Operating Budget.

         (a) Prior to the expected Commercial Operation Date of Sherco
3, each Participant shall provide the Project Manager with a schedule
of its monthly energy requirements from Sherco 3 through the end of the
first full calendar year of commercial operation.  The Project Manager
as agent for the Participants shall then develop and provide each
Participant a budget estimate (the "Operating Budget") of the Operating
Costs anticipated to be incurred during each month from the Commercial
Operation Date to the end of such first full calendar year.  On or
before August l of each year, commencing with the first full year of
commercial operation, each Participant shall provide the Project Manager
with a schedule of its energy requirements through the end of the
following calendar year.  The Project Manager shall then develop and
provide to each Participant a proposed Operating Budget by September l
for the next succeeding calendar year.  Each proposed Operating Budget
shall be supported by detail reasonably adequate for the purpose of each
Participant's reasonable review thereof and shall include, without
limiting the generality of the foregoing, information demonstrating the
basis for all allocations of administrative and general expenses,
staffing allocations and the Project Manager services, and information
demonstrating the basis for any other allocations of expenses between
or among Sherco 3 and the other generating units at the Sherco Plant
Site.  By November 15 of each year, the Management Committee, giving due
consideration to comments by Participants, shall approve an Operating
Budget, in the failure of which the Operating Budget to be used shall
be the one submitted by the Project Manager (with such modifications
therein as the Project Manager shall have proposed prior to such date).

         (b) The Project Manager may propose changes in the Operating
Budget as necessary to reflect changed operating conditions and shall
similarly submit such proposed changes to all Participants who shall
approve or disapprove them in accordance with the provisions of
paragraph (a) of this Section.  The Project Manager shall attempt to
manage, control, operate and maintain Sherco 3 in accordance with the
then current Operating Budget.  Notwithstanding the foregoing, the
Project Manager makes no representation, warranty or promise of any kind
as to the accuracy of any estimate contained in an Operating Budget or
revised Operating Budget or that any such attempt referred to in the
preceding sentence will be successful.

         SECTION 3.3.8.  Operating Account.  Prior to the Commercial
Operation Date of Sherco 3, and on such date as the Project Manager
shall recommend, the Management Committee shall direct the Project
Manager to establish a separate account or accounts ("Operating
Account"), which at the discretion of the Project Manager may be
interest-bearing or non-interest bearing in a bank or banks which insure
deposits, subject to applicable limits, with the Federal Deposit
Insurance Corporation.  The Operating Account shall be held in the names
of all of the ParticipantS.  All payments by the Participants for
Operating Costs after the Commercial Operation Date shall be deposited
by the ParticipantS in the Operating Account and the Project Manager as
agent shall withdraw and apply funds therefrom only as necessary to pay
Operating Costs.

         Prior to the Commercial Operation Date of Sherco 3, the Project
Manager shall establish a minimum amount of working capital for the
Operating Account for the purposes of providing funds to pay the
Operating Costs for Sherco 3.  Such minimum amount shall be based upon
estimates of such Costs for approximately two months of operation of
Sherco 3 plus provisions for adequate fuel inventory.  The amount of
working capital may be revised by the Project Manager at any time.  The
original minimum amount and any change therein shall be allocated among
the ParticipantS in accordance with their Ownership Percentages and
shall be due and payable within fifteen businesS days following
notification of the establishment of the Operating Account or the date
on which any change in such minimum amount shall become effective.  In
the event the Project Manager authorizes a decrease in such minimum
amount, then each Participant shall receive a credit which shall be
equal to its Ownership Percentage of any such decrease.

         Until retirement of Sherco 3 and settlement of all the
obligations relating to Operating Costs, each Participant shall continue
to own and maintain its undivided ownership interest in the Operating
Account.  Such undivided ownership interest of each Participant on any
date shall include a full ownership interest in all amounts deposited
in the Operating Account by such Participant for payment of Operating
Costs and a full ownership interest in all amounts deposited in the
Operating Account and to be distributed to such Participant pursuant to
Section 3.3.9(c) hereof; provided, however, that the Project Manager as
agent shall have the sole right and authority to make withdrawals from
the Operating Account; and provided further, a Participant shall not own
any undivided ownership interest in any amount in the Operating Account
in respect of interest paid into such Account by or on behalf of such
Participant pursuant to the provisions of this Agreement, which amount
shall, if there is only one other Participant, be owned entirely by such
other Participant and credited against payments required to be made into
such Account by such other Participant in the performance of its
obligations under this Agreement, and which amount shall, if there are
three or more Participants, be owned in common by, and credited against
payments required to be made into such Account by, the other
Participants not then in default in the performance of their obligations
under this Agreement in the proportion which their respective Ownership
Percentages bear to the aggregate of their Ownership Percentages (or,
in the case of any payment relating to Variable Operating Costs, in
proportion to the amount of their respective payments of Variable
Operating Costs during the period of default).  In no event shall the
Project Manager commingle any funds deposited in the Operating Account
with any other funds.

         Upon retirement of Sherco 3 and settlement of all the
obligations relating to Operating Costs the Project Manager shall close
the Operating Account and distribute to each Participant its undivided
ownership interest of any balance remaining in said Account, except that
if a Participant shall then be in default with respect to any payment
required to be made under this Agreement, an amount equal to the
liability of such defaulting Participant on account of such default (or
if such amount exceeds such Participant's share of the balance in the
Operating Account, its entire share of such balance) shall first be
distributed to the nondefaulting Participant, or, if there is more than
one nondefaulting Participant, to the nondefaulting Participants in the
proportion which their respective Ownership Percentages bear to the
aggregate of their Ownership Percentages (or, in the case of any payment
relating to Variable Operating Costs, in proportion to the amount of
their respective payments of Variable Operating Costs during the period
of default).

         SECTION 3.3.9.  Operating Costs and Payments

              (a) Fixed Operating Costs. Except as otherwise provided
         herein, each Participant shall be responsible for the payment
         of its respective percentage share of all Fixed Operating
         Costs, which percentage share shall (except as set forth in the
         next sentence) be equivalent to its Ownership Percentage. 
         Fixed Operating Costs relating to Joint Common Facilities will
         be paid by the Participants in accordance with their respective
         Joint Common Facility Percentages.  All fixed operating and
         maintenance costs relating to NSP Common Facilities will be
         paid by NSP.

              (b) Variable Operating Costs.

              (1) When the Project Manager is solely responsible for
         acquiring all fuel for Unit 3, Variable Operating Costs shall
         be shared by each Participant in the ratio that such
         Participant's monthly Net Energy Generation scheduled and
         produced from Unit 3 bears to the total monthly Net Energy
         Generation scheduled and produced from Unit 3.

              (2) In the event any Participant supplies fuel and/or
         transportation by separate arrangement, as specified in Section
         4.3.3 hereof, then Variable Operating Costs and fuel costs
         which are Fixed Operating Costs shall be paid for as follows:
         (i) all items of Variable Operating Costs and Fixed Operating
         Costs attributable to fuel and/or transportation supplied under
         such separate arrangement ("Excluded Items of Variable
         Operating Costs" and "Excluded Items of Fixed Operating Costs",
         respectively) shall be paid for by the Participant supplying
         such fuel and/or transportation; (ii) all items of Variable
         Operating Costs attributable to fuel and/or transportation
         supplied by the Project Manager on behalf of NSP and any other
         Participants which are of the same categories as the Excluded
         Items of Variable Operating Costs shall be shared by NSP and
         each such other Participant each month in the ratio which its
         Net Energy Generation scheduled and produced from Unit 3 in
         such month bears to the total Net Energy Generation scheduled
         and produced from Unit 3 in such month excluding the Net Energy
         Generation of any Participant allocable to fuel and/or
         transportation supplied under a separate arrangement; (iii) all
         remaining items of Variable Operating Costs shall be shared by
         each Participant each month in the ratio which its Net Energy
         Generation scheduled and produced from Unit 3 in such month
         bears to the total Net Energy Generation scheduled and produced
         from Unit 3 in such month; and (iv) all items of Fixed
         Operating Costs attributable to fuel and/or transportation
         supplied by the Project Manager on behalf of NSP and any other
         Participant which are of the same categories as the Excluded
         Items of Fixed Operating Costs shall be shared by NSP and each
         such other Participant in the ratio which its Ownership
         Percentage bears to the Ownership Percentages of all
         Participants other than the Participant supplying fuel and/or
         transportation under a separate arrangement.

              (3) Each Participant shall have the right to make whatever
         financial arrangements it may desire, whether by lease,
         security transaction or otherwise, for the discharge of its
         fuel payment obligations so long as such arrangements do not
         adversely affect the rights of the other Participants.

              (c) Payment and Settlement

              (1) Except as provided in Section 3.3.9(b) hereof, the
         Project Manager shall be responsible for making payment to
         third parties of all Operating Costs to the extent that funds
         are available therefor in the Operating Account.

              (2) Beginning with the month immediately succeeding the
         first month in which Operating Costs are paid;, by the
         twentieth day of such month the Project Manager shall notify
         each Participant of the actual amount of such Costs for the
         preceding month and of the amount to be paid by each
         Participant.  On or before the last banking day of the month of
         such notification, each Participant shall deposit immediately
         available funds into the Operating Account in an amount equal
         to the sum of (i) its respective share of the Fixed Operating
         Costs as provided herein and (ii) Variable Operating Costs for
         which it is responsible pursuant to paragraph (b) hereof.

              (3) Each Participant shall have ninety days to question or
         contest the correctness of charges for Operating Costs after
         which time the corrections of such charges shall be
         conclusively presumed.  In the event any Participant by timely
         notice questions or contests the correctness of any such
         charge, the Project Manager shall within 55 days following such
         notice from a Participant notify each Participant of the amount
         of any error and the amount of reimbursement, if any, each
         Participant is required to make or is entitled to receive in
         respect of such error.  Not later than the third banking day
         after receipt of such notice from the Project Manager, each
         Participant required to make reimbursement shall deposit the
         amount specified in such notice into the Operating Account in
         immediately available funds.  From the amount so deposited, the
         Project Manager shall immediately thereafter distribute in
         immediately available funds to each Participant entitled to
         receive such reimbursement the amount such Participant is
         entitled to receive except if any such Participant is then in
         default in respect of any payments required to be made under
         this Agreement, an amount equal to such defaulting
         Participant's share of the amount so deposited with respect to
         such reimbursement shall be retained in the Operating Account
         and distributed in accordance with the provisions of Section
         3.3.8 hereof.

              The Project Manager shall have no responsibility liability
         for the failure of any Participant to deposit funds as provided
         in this Section 3.3.9.  The Project Manager will provide each
         Participant with such information as is reasonably required by
         such Participant in order to account for payments made pursuant
         to this Section 3.3.9 on such Participant's books.

         SECTION 3.3.10.  Late Payments.  Payments of a Participant not
made when due shall bear interest from the due date at the Agreed Rate.

         SECTION 3.3.11.  Administrative and General Costs.  The portion
of the Project Manager's administrative and general costs appropriately
allocable to Cost of Construction and Operating Costs hereunder shall
be determined from time to time in accordance with the methods and
procedures described in Exhibit I hereto.  Such allocation for any
fiscal year shall be subject to review after the conclusion of such year
by a nationally recognized firm of certified public accountants selected
by the Management Committee pursuant to Section 3.3.14 hereof and shall
be subject to revision based upon considerations of fairness and equity.

         SECTION 3.3.12.  Project Insurance

              (a) From and after the date hereof and at all times during
         the construction of Sherco 3, the Project Manager shall carry
         in the name of itself and the Participants, in proportion to
         their respective ownership interests to be owned by them after
         the Closings provided for in Article Two hereof, insurance,
         including fire and extended coverage and installation floater
         insurance, in an amount and including such risks as is
         consistent with the Project Manager's customary practices and
         in accordance with Prudent Utility Practice.  The Project
         Manager shall also procure and maintain public liability
         insurance in the amount of not less than ten million dollars
         subject to a deductible determined by the Project Manager
         naming the Participants as insureds.  The foregoing policy
         shall contain, where necessary, cross liability endorsement and
         waivers of subrogation, or equivalent releases, which shall
         protect the Participants.  The Project Manager shall also
         reasonably satisfy itself that all contractors, subcontractors,
         engineers, and all equipment suppliers or manufacturers have
         adequate insurance and limits thereof, with carriers approved
         by the Project Manager, for workers' compensation, public
         liability, contractors' liability and such other hazards as the
         Project Manager shall deem appropriate with respect to Sherco
         3, or the Project Manager, at its option, may provide for an
         insurance program of the nature of a "wrap-up" which shall
         combine all hazards in one policy, with all parties, including
         owners, contractors, subcontractors, but not including engineer
         and equipment suppliers and manufacturers, involved in Sherco
         3 being insured thereunder as their interests may appear.  The
         Project Manager will require engineer and equipment suppliers
         and manufacturers to have such insurance as the Project Manager
         deems appropriate.  The aggregate cost of all insurance
         procured pursuant to this paragraph (a) and all uninsured
         losses shall be considered a Cost of Construction and as such
         shall be apportioned among the Participants and paid pursuant
         to Sections 3.3.3 and 3.3.6 hereof.

              (b) During the period of its operation of Sherco 3
         hereunder, the Project Manager shall carry in the name of the
         Participants as their interests appear the public liability
         insurance referred to in the preceding paragraph (a) and
         insurance covering workers' compensation and property, in such
         amounts and with such deductible or self-insurance features as
         is consistent with the Project Manager's customary practices. 
         The aggregate cost of all such insurance and uninsured losses
         shall be considered a Fixed Operating Cost.

              (c) The Project Manager shall promptly provide copies of
         all insurance policies or certificate therefor and make
         available notices with respect thereto to the other
         Participants for insurance carried by the Project Manager
         pursuant to this Section 3.3.12.  Each other Participant may
         also maintain additional or other insurance at its own cost and
         expense which it deems necessary or advisable to protect its
         respective interest in Sherco 3, provided that such additional
         insurance does not reduce or diminish in any way the coverage
         of the insurance procured and maintained by the Project Manager
         pursuant to this Section 3.3.12.

         SECTION 3.3.13.  Taxes.

              (a) The Participants shall use their best efforts to have
         any taxing or other authority levying any taxes or assessments
         on Sherco 3, levy such taxes or assessments directly against
         the ownership or beneficial interest of each Participant.

              (b) All taxes or assessments or payments in lieu thereof
         levied against or with respect to each Participant's undivided
         ownership interest in Sherco 3 under statutes now or hereafter
         in effect shall be the sole responsibility of, and shall be
         paid by, the Participant upon whose interest said taxes or
         assessments or payments in lieu thereof are levied.

              (c) If any property taxes or other taxes or assessments or
         payments in lieu thereof are levied on Sherco 3, or any
         interest or rights therein, in a manner other than as specified
         in paragraph (a) of this Section, such taxes or. assessments or
         payments in lieu thereof shall be apportioned among the
         Participants in accordance with their respective ownership
         interests; provided, however, that each Participant shall be
         entitled to the entire benefit, to the extent of actual
         realization, of all exemptions from or reductions of taxes,
         payments in lieu of taxes, assessments, impositions, charges
         and related costs of every kind and nature, foreseen or
         unforeseen, settled or pending settlement, including but not
         limited to property, sales, use and payroll taxes, connected
         with or arising out of the construction, ownership, operation,
         alteration, repair, rebuilding, use or retirement of Sherco 3
         or any part thereof, which may be realized under the provisions
         of the Constitutions of the State of Minnesota or the United
         States of America, statutes, ordinances, rules, regulations or
         laws applicable to such Participant.

              (d) Each of the Participants claiming exemption from any
         taxes or assessments or payments in lieu thereof shall be
         responsible for and shall pay all expenses in connection with
         the sustaining or determination of such claims, and each of the
         other Participants shall lend all reasonable cooperation in
         connection with the filing of tax renditions and reports and in
         connection with the making of any payment under protest as may
         be requested by each Participant claiming an exemption.  No
         Participant who is exempt from any taxes assessed against any
         or all of the other Participants shall be obligated to make any
         contribution toward such taxes to the extent of the exemption.

              (e) Participants shall within 30 days of payments under (b)
         above send a receipt of such payment to the Project Manager. 
         Failure to pay such taxes shall be considered default in
         payment under Article 5.1 and the nondefaulting Participants
         may cure the default to avoid the imposition of a lien or other
         consequence on the Sherco 3 Project.

keep books of account and records concerning details of cost applicable
to Sherco 3.  Such books and accounts shall be kept in accordance with
the Uniform System of Accounts.  The Project Manager shall arrange for
annual audits of such books of account and records by a nationally
recognized firm of certified public accountants selected by the
Management Committee.  The auditing firm shall certify that such books
of account and records are in accordance with this Agreement and in
accordance with sound accounting practice. Prior to the Commercial
Operation Date, the costs of such audits shall be a Cost of Construction
and thereafter such costs shall be a Fixed Operating Cost.

Participant shall have the right from time to time to conduct management
and operating audits, at its own cost, of the Project Manager's
performance as agent hereunder including audits of all books, records
and other documents regarding Operating Costs and Cost of Construction
sufficient to allow it to determine that such costs attributed to Sherco
3 by the Project Manager are appropriate.  Such audits may; be made
either by its own officers and employees or through its duly authorized
agents or representatives.  No payment made by any Participant shall
constitute a waiver of the right of such Participant to question or
contest the correctness of any charge or credit by the Project Manager
hereunder.  The Project Manager shall cooperate with each Participant
in the conducting of any such audit and, subject to the applicable
regulations of any regulatory agency having jurisdiction and the
provisions of Section 5.4.2 hereof, give each other Participant
reasonable access to all contracts, records and other documents relating
to Sherco 3.

         SECTION 3.3.16.  Right to Copies.  SOUTHERN MINNESOTA, UNITED
MINNESOTA and any successor Project Manager hereunder shall each be
entitled to copy any and all (i) contracts, books, records, reports and
other documents and papers to which SOUTHERN MINNESOTA, UNITED
MINNESOTA, their respective officers, employees, duly authorized agents
or representatives and consultants or any successor Project Manager is
permitted access, or which NSP has agreed shall be available for audit,

thereof to the extent required by applicable law or to the extent
required in connection with the sale of its securities and each may
provide any such copy or disclose the contents thereof to any
independent consultant responsible for reporting to it with respect to
the feasibility of Sherco 3 or to any trustee, mortgagee or security
holder for the holders of its indebtedness.

         SECTION 3.3.17.  Confidentiality.  Each Participant agrees to
comply with any provisions in any contract with vendors or consultants
concerning the confidentiality of the terms and provisions thereof and
will not sell or otherwise transfer the information contained therein
to any person or entity.

         SECTION 4.2.2.  Disposition of Output liter Commercial
Operation.

              (a) Net Effective Generating Capability. The Project
         Manager shall keep the system dispatcher of each Participant
         advised of the Net Effective Generating Capability.

              (b)Scheduling

              (l) Each Participant shall be entitled to schedule Capacity
         and Energy from Unit 3 and shall be entitled to receive such
         Capacity and Energy as scheduled, subject to the provisions of
         this Agreement, up to the amount of its Entitlement.

              (2) When a Participant schedules Capacity and Energy from
         Unit 3, each Participant shall, unless otherwise determined by
         the Management Committee, schedule for its account its share of
         Minimum Net Generation which shall be the product of its
         Ownership Percentage and the Minimum Net Generation established
         for Unit 3.  At any time any Participant has scheduled an
         amount of Capacity from Unit 3 in excess of the product of its
         Ownership Percentage and Minimum Net Generation, then unless
         otherwise determined by the Management Committee, the other
         Participants whose schedules are less than their respective
         Ownership Percentages of such Minimum Net Generation shall
         schedule on a pro rata basis, in the proportion which their
         respective Ownership Percentages bear to each other, the
         remaining amount of Minimum Net Generation.

              (3) Operation of Sherco 3 by the Project Manager and a
         Participant's right to receive the output thereof shall be
         subject to scheduled outages or curtailments, Operating
         Emergencies aid unscheduled outages or curtailments of Unit 3.

              (c) Substitution of Another Resource. In the event, and
         only in the event, the Project Manager voluntarily ceases to
         operate Sherco 3 solely because of the availability of Energy
         to NSP from another source or sources, the average cost of
         which is projected to be lower than the cost of Energy
         generated by Unit 3 would be during the period of such
         cessation in operation, NSP shall make available to the other
         Participants replacement Energy from such other sources during
         the period of such cessation in operation.  The amount of such
         replacement Energy to be made available to other Participants
         during such period shall be the amount of Energy requested by
         such Participants, but not in excess of the amount to which
         such Participants would have been entitled during such period
         had the operation of Sherco 3 not ceased.  The cost of such
         replacement Energy shall be the estimated cost which would have
         been incurred by the other Participants for Energy generated by
         Unit 3 if Sherco 3 were continued in operation during such
         period at a level equal to the Energy requested by the other
         Participants plus NSP's share of the Minimum Net Generation.

              (d) Transactions With Other Systems. Each
         Participant shall be entitled to dispose of its Entitlement or
         any part thereof through scheduled transactions with other
         systems or agencies, or with one or more of the other
         Participants.

         Manager as agent for the Participants) shall be able to locate
         and arrange for a source of fuel for Unit 3 and

              (1) the total cost per Btu of such fuel, including, without
         limitation, all brokerage, transportation, handling, testing
         and storage charges, is equal to or lower than the cost of fuel
         which the Project Manager would be able to procure for Unit 3
         for the same period of time;

              (2) the quality and characteristics of such fuel are in all
         respects equal to or better than and compatible with those of
         the other fuel being utilized or to be utilized for Unit 3
         during the period of such contract, and such fuel is in all
         respects compatible with Unit 3 and will enable Unit 3 to
         operate at normal operational levels in compliance with all
         governmental regulations applying thereto;

              (3) transportation for such fuel can be arranged which is
         at least as reliable as transportation which would be available
         for the other sources of fuel for Unit 3 for the same period of
         time, and such transportation is compatible with the
         transportation and fuel delivery facilities of Unit 3;

              (4) procurement of such fuel would not interfere with,
         diminish any benefits of or replicate any other fuel
         arrangement which the Project Manager has procured for or
         entered into with respect to Unit 3, including any options or
         rights for renewals or extensions of contracts, and would not
         interfere with, diminish any benefits of or replicate any
         transportation arrangements, agreements or tariffs;

              (5) procurement of such fuel would not increase or diminish
         the level of fuel supply in the Unit 3 coal stockpile
         determined by the Project Manager to be the appropriate level
         therefor;

              (6) the vendor of such fuel is willing to enter into a
         contract with the Project Manager (as agent for the
         Participants) on terms and conditions no less favorable to the
         Participants than those then being bargained for by the Project
         Manager; and

              (7) the necessary contracts and arrangements are for a
         period of 12 months or longer;

then the Project Manager as agent for the Participants, shall enter into
a contract to obtain such fuel for Unit 3 and shall thereafter
exclusively administer such contract and all transportation arrangements
associated therewith, all costs and benefits of such contract to be
shared by all of the Participants pursuant to the provisions of this
Agreement.  No Participant (other than the Project Manager as agent for
the Participants) shall enter into any arrangement or agreement with
respect to the procurement of fuel for Unit 3 on behalf of the other
Participants.

              (b) Any Participant which has an opportunity to procure or
         participate in a fuel supply arrangement which meets all of the
         conditions specified in clauses (1) through (7) of the
         preceding paragraph (a), but for which such Participant cannot,
         because of legal restrictions, obtain beneficial financing if
         the economic benefits, if any, of such fuel supply arrangement
         are shared with the other Participants, shall be permitted to
         supply, solely for its own account, up to its proportionate
         share of the fuel requirements for Unit 3 from such fuel supply
         arrangement, upon the following conditions.  The Participant
         proposing to participate in such fuel supply arrangement shall
         give the Project Manager written notice of its intention to
         supply part or all of its proportionate share of the fuel
         requirements for Unit 3, the period of time for which it
         proposes to supply such requirements and the percentage of its
         proportionate share of such requirements which it proposes to
         provide.  Such notice shall be tendered at least one year prior
         to the date of the first contemplated delivery of fuel from
         such fuel supply arrangement.  At least one year prior to the
         first scheduled delivery of fuel from any such arrangement, the
         Participant proposing to participate in the arrangement shall
         enter into a valid, binding and enforceable contract for such
         fuel and transportation thereof providing by its terms for such
         Participant to be solely responsible for all administration
         with respect thereto, including coordination with the mine
         operator, scheduling of deliveries, transportation
         arrangements, testing and enforcement.  Such Participant shall
         schedule deliveries to Unit 3 under such arrangement with the
         Operating Committee.

         For the duration of any such notice of intention,

              (1) The Project Manager shall have no obligation to
         purchase, arrange for or contract for this purchase of fuel for
         Unit 3 in the amount specified in the notice of intention; and

              (2) Any Participant which gives any such notice of
         intention to supply fuel shall indemnify the other Participants
         for any and all damages, costs and expenses which result,
         directly or indirectly, from any such notice of intention, from
         any such fuel supply arrangement or from the failure of supply
         of fuel as contemplated in such notices or arrangement.

         If, at any time, any one or more deliveries of fuel from any
such fuel supply arrangement fail in any respect to satisfy the
requirements as specified in the preceding paragraph (a) or are
incompatible with Unit 3 or any governmental regulations applying
thereto, then the Project Manager may decline to use the fuel from any
such delivery, and the Project Manager may order the controlling
participant to suspend further deliveries from such fuel supply
arrangement until it receives adequate assurances that all future
deliveries of fuel will conform to all of the requirements of Unit 3
and/or to the delivery schedules.

         The Project Manager shall not be liable to any participant for
any actions taken by it under this paragraph (b), and the Participant
participating in any such fuel supply arrangement shall indemnify and
hold harmless the Project Manager and the other Participants from and
against any and all costs, expenses, claims, judgments and fines,
including legal fees incurred in defense of any lawsuit or other
proceeding, as a result of any such action taken by the Project Manager,
except the Project Manager shall not be so indemnified and held harmless
from the payment of legal fees incurred in defense of any lawsuit
brought by a Participant proposing to participate in such arrangement
seeking specific performance or injunctive relief against the Project
Manager to reverse the Project Manager's determination that such a
proposed arrangement does not comply with the terms and conditions of
this paragraph (b).

              (c) Any Participant shall have the right to arrange for
         transportation by separate arrangement of its proportionate
         share of the fuel requirements for Unit 3 provided such
         transportation is compatible with the fuel delivery facilities
         of Unit 3 and the impact of such transportation on the overall
         fuel arrangement for Unit 3 meets all the conditions specified
         in clauses (1) through (7) of the preceding paragraph (a) to
         the extent applicable.  Scheduling of deliveries and
         administration of any contractual arrangements associated
         therewith shall be coordinated through the Operating Committee. 
         If, in order for such Participant to obtain beneficial
         financing for such transportation, it shall be necessary for it
         to have sole ownership of the fuel being transported, then
         legal title to such fuel shall be conveyed to such Participant
         by the Project Manager or the supplier of such fuel if such
         fuel arrangement meets all of the conditions specified in
         clauses (1) through (7) of the preceding paragraph (a) to the
         extent applicable.

         ARTICLE 4.4.  OTHER OPERATING MATTERS

         SECTION 4.4.1.  Maintenance Schedule.  The Project Manager
agrees to submit to the Participants on or before September 1 of each
year a scheduled maintenance plan for the ensuing five calendar years. 
Each such plan shall describe in reasonable detail the contemplated time
and duration of each outage and maintenance work to be done and the
estimated cost thereof.  The Management Committee, giving due
consideration to matters and comments submitted by all Participants,
shall adopt a scheduled maintenance plan by each November 1.  If the
Management Committee fails to adopt a plan by such time, the plan to be
utilized shall be the one submitted by the Project Manager.  Scheduled
maintenance plans may be changed by the Project Manager from time to
time as deemed appropriate by the Project Manager and when so changed
shall be delivered to the Participants and adopted as provided above in
this Section.  The Project Manager makes no representation, warranty or
promise of any kind as to the accuracy of any estimate or other
information contained in any scheduled maintenance plan and in no event
shall the Project Manager have any liability to any of the Participants
in these regards.

         SECTION 4.4.2.  Operating Emergency.  The Project Manager shall
take any and all steps required by Prudent Utility Practice to terminate
any Operating Emergency, subject to the provisions of this Section.  As
soon as practicable after the commencement of an Operating Emergency,
the Project Manager shall advise the Participants of the occurrence of
such Emergency, its nature and the steps taken or to be taken to
terminate the Operating Emergency, including a preliminary estimate of
the expenditures required to terminate the Operating Emergency.  In the
event the Project Manager determines the estimated amount required to
terminate the Operating Emergency exceeds the amount which it is
authorized to expend hereunder, the Project Manager shall so notify the
Participants and shall call a meeting of the Operating Committee to be
held not later than five days following such determination.  At such
meeting the Project Manager shall submit the following information:

              (a) The estimated date when the Operating Emergency can be
         terminated.

              (b) The person or persons who the Project Manager proposes
         would perform the work and furnish the materials required toe
         terminate the Operating Emergency.

              (c) The estimated amount of overtime, if any, which would
         be paid in order to expedite the termination of the Operating
         Emergency.

              (d) The costs proposed to be capitalized, facilities to be
         retired, and salvage to be realized.

              (e) The costs proposed to be charged as maintenance
         expense.

              (f) Such other information as may be necessary and required
         by Operating Committee to determine the manner in which the
         Operating Emergency is to be terminated.

The Operating Committee shall review and recommend to the Management
Committee the items as set forth in this Section or recommend an
alternative thereto.

         SECTION 4.4.3.  Reactive Generation.  Unless otherwise mutually
agreed by the Participants, each Participant shall provide the reactive
power requirements of its electric system.  The Project Manager will,
at all times, operate Sherco 3 in a manner consistent with the safe
operation of the NSP electric system and systems interconnected with the
NSP system.  The Project Manager will not, however, vary the generation
of reactive power supplied by Unit 3 in such a manner as to impair the
ability to generate real power for the benefit of any Participant except
during emergencies.  The Project Manager will not be required, at any
time, to operate Sherco 3 in a manner which is intended to supply
reactive power generated by Unit 3 to the systems or electric loads of
any of the Participants other than NSP.

         SECTION 4.4.4.  Initial Training and Startup Expenses.  Up to
the Commercial Operation Date of Sherco 3, the Project Manager shall
accumulate and charge the initial training and startup expenses to the
Cost of Construction.  Such expenses shall be accounted for in a manner
which will provide identification thereof.

         SECTION 4.4.5.  Metering.  The Project Manager shall install and
maintain the necessary metering equipment to determine the amounts of
net Capacity and Energy from Unit 3 at the Point of Delivery.  Metering
records shall be available at all times to authorized representatives
of the Participants.  Each meter used shall, by comparison with accurate
standards, be tested and calibrated by the Project Manager at
approximate intervals of twelve months.  If a meter shall be found not
registering within 1% accuracy, it shall be restored to an accurate
condition or an accurate meter shall be substituted.  The results of all
tests and calibrations shall be open to examination by the Participants
and a report of every test shall be furnished immediately to the
Participants.  Any meter tested and found to be within 1% accuracy shall
be considered to be accurate. If, as a result of any test, any meter is
found to register not within 1% accuracy, the readings of such meter
previously taken shall be corrected according to the percentage of
inaccuracy so found but no such correction shall extend beyond sixty
days previous to the day on which such inaccuracy was discovered by such
test.  If any metering equipment fails to register or if the meter
registration is erratic, the Capacity and Energy produced shall be
determined by the Participants.  All costs incurred in connection with
such metering equipment and compliance with the provisions of this
Section shall be considered a Fixed Operating Cost and as such shall be
borne by the Participants in proportion to their respective Ownership
Percentages.


                                 CHAPTER FIVE

                              GENERAL PROVISIONS

         ARTICLE 5.1.  DEFAULTS

         SECTION 5.1.1.  Covenant to Perform.  Each Participant covenants
to pay all monies and to perform all other obligations agreed to be paid
or performed under this Agreement.  This Article provides for
consequences and remedies relating to financial defaults.  For the
purposes of this Article a "default" shall occur if any Participant
fails to make any payment in the time and manner provided by this
Agreement, provided that Section 5.6.11 shall not apply until a written
notice of default has been given to the defaulting Participant.  Such
notice shall be given by the Project Manager, but upon failure of the
Project Manager to do so it may be given by any Participant.

         SECTION 5.1.2.  Initial Procedures.

              (a) Following a default by a Participant, the nondefaulting
         Participants shall make payments and take actions necessary to
         cover the default.  In the case of a default in the payment of
         Cost of Construction relating to

         Joint Common Facilities, the amount in default shall be paid by
         each nondefaulting Participant in the ratio that its Joint
         Common Facility Percentage bears to the total Joint Common
         Facility Percentages of all nondefaulting Participants.  In the
         case of a default in the payment of any other Cost of
         Construction or Operating Costs, the amount in default shall be
         paid by each nondefaulting Participant in the ratio that its
         Ownership Percentage bears to the total Ownership Percentages
         of all nondefaulting Participants.  The Project Manager may
         notify the nondefaulting Participants by telephone or telegraph
         if there exists an immediate need for the advancement of funds
         to cover a default.  Within three banking days of the receipt
         of such notice, each nondefaulting Participant shall advance
         the funds requested to the Project Manager in such manner as
         the Project Manager may request.  Neither the advance of funds
         pursuant to such a request nor the covering of a default shall
         constitute an: election of rights or option under this Article
         5.1.

              (b) The failure by UNITED MINNESOTA to cover a default of
         another Participant in accordance with paragraph (a) shall not
         constitute a default for purposes of Sections 5.1.7 and 5.6.11
         hereof.

         SECTION 5.1.3.  Payment in Event of Dispute.  If a Participant
disputes the existence or extent of any failure to make any payment
hereunder, it shall nevertheless make such payment under written protest
directed to each of the other Participants.  Such payments of a
Participant not made when due shall bear interest at the Agreed Rate.

         SECTION 5.1.4.  Option to Abandon.  If a payment default should
continue for a period of 120 days after the due date thereof, the
Management Committee, subject to the vote adjustment required by Section
5.6.11, may elect to discontinue the Sherco 3 Project immediately and
liquidate the same for the benefit of the Participants.  In such event,
the defaulting Participant shall not be relieved of any of its
obligations then existing or thereafter existing hereunder and shall be
liable for any and all costs incurred by the nondefaulting Participants
in covering such default; and any provisions of this Agreement to the
contrary notwithstanding, the defaulting Participant shall be liable for
all costs directly attributable to the discontinuance of the Sherco 3
Project (including, without limitation, all cancellation charges and
penalties imposed by contractors, engineering companies, constructors,
equipment suppliers and suppliers of materials and services) and shall
indemnify the nondefaulting Participants for any and all such costs paid
or borne by them.

         SECTION 5.1.5.  Right to Cure Defaults.  A Participant in
default for failure to make any payment of Cost of Construction required
to be paid by it prior to the Commercial Operation Date shall have the
right to cure such default by paying the amounts in default, plus
interest thereon at the Agreed Rate, to the other Participant or
Participants that shall have paid such amounts or, to the extent no
other Participant shall have paid such amounts, by paying such amounts,
plus interest thereon at the Agreed Rate, into the Construction Account;
provided, however, that any such payment to another Participant may be
made only within 120 days after the date of default unless such other
Participant shall agree to accept payment at a later date; and provided
further, that no Participant shall have the right to cure any such
default after the Commercial Operation Date.  A Participant in default
for failure to make any payment required to be made by it on or after
the Commercial Operation Date may cure such default as provided in
Section 5.1.7 hereof.

         SECTION 5.1.6.  Adjustment to Ownership Percentages and Joint
Common Facility Percentages.

              (a) If necessary to reflect defaults by one or more
         Participants, upon completion of construction and after the
         adjustments in the Participants' investments in Joint Common
         Facilities pursuant to Section 2.2.2 (d) hereof, the Management
         Committee shall review the investment made by each Participant
         hereunder through the completion of construction and shall re-
         determine the Ownership Percentages and Joint Common Facility
         Percentages of the respective Participants in accordance with
         the formula in (b) and (c) below with the intent that, if the
         total investment by any Participant hereunder (including Cost
         of Construction of Joint Common Facilities to the extent
         allocable to Sherco 3, all other Cost of Construction and
         investment in NSP Common Facilities to the extent allocable to
         Sherco 3) represents a percentage of. the total investment by
         all Participants hereunder (including Cost of Construction of
         Joint Common Facilities to the extent allocable to Sherco 3,
         all other Cost of Construction and investment in NSP Common
         Facilities to the extent allocable to Sherco 3) which is
         different from its Ownership Percentage, then the Ownership
         Percentage of such Participant shall be revised to equal such
         other percentage.  All amounts used in the formula shall be
         determined from Sherco 3 Project accounting records.

              (b) The Ownership Percentage of each Participant shall be
         re-determined in accordance with the following formula:

         OP' = Csp + Cep + Cjsp + Cmp x 100
               ----------------------
                CS + CE  + Cjs  + Cm

Where:

         OP   Such Participant's revised Ownership Percentage, as to be
              determined from the formula;

         Cs   Total Cost of Construction of Sherco 3 excluding Joint
              Common Facilities;

         Csp  Such Participant's investment in Sherco 3 excluding Joint
              Common Facilities;

         Ce   is as defined in Section 2.2.2(b);

         Cep  is as defined in Section 2.2.2(b);

         Cjs  Total investment in Joint Common Facilities to the extent
              allocable to Sherco 3.  This amount is equal to the amount
              Cj less the amount Cx, where Cj and Cx are as defined in
              Section 2.2.2(b);

         Cjsp  Such Participant's investment in Joint Common Facilities
               to the extent allocable to Sherco 3. This amount shall be
               equal to the amount Cjp less the amount Cxp, where Cjp
               shall be equal to such Participant's investment in Joint
               Common Facilities (including all adjustments pursuant to
               Section 2.2.2(d)) and Cxp is as defined in Section
               2.2.2(b);

         Cm   is as defined in Section 2.2.2(b); and

         Cmp  Such Participant's investment, if any, in NSP Common
              Facilities Modifications to the extent allocable to Sherco
              3.  Cmp for NSP shall equal the sum of (i) the total
              investment by NSP in NSP Common Facilities Modifications
              identified on Exhibit B-1 hereto on the date hereof less
              0.134 times the total investment by all Participants in
              such Modifications plus (ii) the total investment by NSP
              in NSP Common Facilities Modifications made pursuant to
              Section 2.2.6 hereof less the portion of the investment
              therein made by all Participants which is allocable to
              generating units other than Sherco 3.  Cmp for each other
              Participant shall equal such Participant's total
              investment, if any, in NSP Common Facilities Modifications.

              (c) After the Ownership Percentage of each Participant has
         been re-determined, its Joint Common Facility Percentage shall
         be re-determined in accordance with the following formula:

                           OP
                           ---
         JP' = Csp + Cjp - 100 (Cs) + Cmp - Cmo
               -------------------------------- x 100
                              CJ

Where:

         JP'  Such Participant's adjusted Joint Common Facility
              Percentage, as to be determined from the formula;

         Cj
         and
         Cmo  are defined in Section 2.2.2(b); and

         Cjp, Cmp, OP', Cs and Csp are as defined above in this Section
5.1.6.

         The re-calculation of the Joint Common Facility Percentages
under this paragraph (c) shall be made after giving effect to the
reclassification as Joint Common Facilities, pursuant to Section 2.2.5
hereof, of those NSP Common Facilities listed as "Essential Equipment"
on Exhibit B-1 hereto.

              (d) After any adjustment to the Ownership Percentage or
         Joint Common Facility Percentage of the Participants as
         provided above, each Participant shall own undivided ownership
         interests in the Joint Common Facilities and in the remainder
         of Sherco 3 equal to its Joint Common Facility Percentage and
         Ownership Percentage, respectively, as so finally established. 
         Any Participant whose Ownership Percentage or Joint Common
         Facility Percentage as so finally established under this
         Section 5.1.6 is less than that originally set forth in Section
         2.1.1 or Exhibit B-2 hereof, respectively, (i) shall deliver to
         each other Participant or Participants whose corresponding
         Percentage is greater than that originally set forth such
         deeds, bills of sale, certificates and opinions as such other
         Participant shall request to evidence such interest and (ii)
         shall take such action as shall be necessary so that such
         interest shall be owned by such other Participant free and
         clear of any mortgages and other liens and encumbrances, except
         those permitted by Section 1.2.2(d) hereof.

              (e) Nothing in this Section 5.1.6 shall be construed to
         relieve a Participant of any liability for failure to make any
         payment hereunder.

         SECTION 5.1.7.  Loss of Entitlement.  A Participant in default
for failure to make any payment accruing on or after the Commercial
Operation Date which continues for a period of 60 days after the due
date thereof shall lose its Entitlement.  The Capacity and Energy
unavailable to a defaulting Participant by operation of this Section may
be thereafter utilized by each nondefaulting Participant during the
period of default in the proportion that its Ownership Percentage bears
to the total of the nondefaulting Participants' Ownership Percentages
as if such Capacity and Energy were a part of the nondefaulting
Participants Entitlement.  For a period of 730 days after the date of
default, such utilization by any nondefaulting Participant shall be on
an interruptible basis until all amounts in default are paid by the
defaulting Participant, together with interest at the Agreed Rate. 
After such period, such utilization by any nondefaulting Participant
shall be on a firm basis for one or more one-year periods; provided,
however, that at the end of any such one-year period, to defaulting
Participant shall regain its Entitlement if (i) six months or more
before the end of such one-year period, the defaulting Participant gives
written notice to such nondefaulting Participant of its intention to pay
all amounts in default and (ii) prior to the end of such one-year
period, the defaulting Participant pays all amounts in default, together
with interest at the Agreed Rate.  Nothing in this Section shall be
construed to relieve a defaulting Participant of any liability for its
default including reimbursement to nondefaulting Participants for all
payments made in respect of the defaulting Participant's obligation to
make payments with the exception of payments for Variable Operating
Costs which shall be borne solely by the nondefaulting Participants in
proportion to their receipt of Energy associated with utilization of a
defaulting Participant's Entitlement.

         SECTION 5.1.8.  Actions to Enforce.  In addition to the rights
granted in this Article 5.1, the Participants may take any action in law
or equity, including an action for specific performance, to enforce this
Agreement in accordance with the terms hereof.

         SECTION 5.1.9.  NSP to Continue as Project Manager. 
Notwithstanding any other provisions of this Article, if NSP is the
Participant in default, NSP shall continue to perform its duties as
Project Manager hereunder until removed in accordance with the
provisions hereof.

         ARTICLE 5.2.  DAMAGE OR DESTRUCTION.

         SECTION 5.2.1.  Covered by Insurance.  Subject to the receipt
of all requisite approvals of any governmental agency having
jurisdiction, in the event Sherco 3 or any portion thereof should be
damaged or destroyed and the cost of repairs or reconstruction is
estimated to be less than or equal to the aggregate amount of insurance
coverage (including any deductible) procured and maintained by the
Project Manager pursuant to Section 3.3.12 of this Agreement, carried
and covering the cost of such repairs and reconstruction, then, unless
the Management Committee determines not to repair or reconstruct Sherco
3, the Project Manager shall cause such repairs or reconstruction to be
made so that Sherco 3 shall be restored to substantially the same
general condition, character and use as existed prior to such damage or
destruction.

         SECTION 5.2.2.  Not Covered by Insurance.  Subject to the
receipt of all requisite approvals of any governmental agency having
jurisdiction, in the event Sherco 3 or any portion thereof should be
damaged or destroyed and the cost of repairs or reconstruction is
estimated to be more than the aggregate amount of insurance coverage
(including any deductible) procured and maintained by the Project
Manager pursuant to Section 3.3.12 of this Agreement carried and
covering the cost of such repairs or reconstruction, then, if the
Management Committee determines to repair or reconstruct Sherco 3, the
Project Manager shall cause such repairs or reconstruction to be made
so that Sherco 3 shall be restored to substantially the same general
condition, character and use as existed prior to such damage or
destruction, and the Participants shall share the costs of such repairs
or reconstruction in excess of available insurance proceeds in
proportion to their respective Ownership Percentages.  In the absence
of such determination, the Project Manager shall not cause such repairs
or reconstruction to be made and the insurance proceeds received as a
result of such damage or destruction shall be deposited in the
Construction Account (if the damage or destruction occurred prior to the
Commercial Operation Date) or the Capital Account (if the damage or
destruction occurred on or after the Commercial Operation Date) and
expended or distributed to the Participants in accordance with Section
3.3.2 or Section 3.3.5 hereof.

         If repairs or reconstruction are not made in accordance with the
foregoing but one or more Participants desire to repair or reconstruct
Sherco 3, then each other Participant shall sell its undivided ownership
interest in Sherco 3 to the Participant or Participants which desire to
repair or reconstruct Sherco 3 for a purchase price equal to the product
of the salvage value of Sherco 3 and the selling Participant's Ownership
Percentage.  The Participants agreeing to repair or reconstruct Sherco
3 shall share the cost of such purchase in the ratio of their respective
Ownership Percentages.

         ARTICLE 5.3.  RETIREMENT

         SECTION 5.3.1.  Date of Retirement.  The determination to retire
Sherco 3 shall be made by the Management Committee; provided, however,
that no determination to retire Sherco 3 during the first forty years
of its commercial operation shall be effective without the approval of
NSP, SOUTHERN MINNESOTA and UNITED MINNESOTA so long as each owns an
undivided interest in Sherco 3.

         SECTION 5.3.2.  Retirement Costs.  All costs less salvage
credits, if any, associated with retirement of Sherco 3, including,
without limitation: dismantling, demolishing and removal of equipment,
facilities and structures; security; maintenance; and disposing of
debris, shall be shared by the Participants in proportion to their
Ownership Percentages.  Payments for these costs less salvage credits,
if any, as they are expected to be incurred, shall be made in accordance
with the provisions of Section 3.3.4, Section 3.3.5, and Section 3.3.6. 
If such salvage credits exceed such costs, the difference shall be
shared by the Participants in proportion to their respective Ownership
Percentages.  To the extent requested by NSP, the Participants other
than NSP each agrees to sell to NSP its interest in Common Facilities
needed by NSP in the operation of any other generating unit at the
Sherco Plant Site.

         ARTICLE 5.4.  CERTAIN ADDITIONAL AGREEMENTS

         SECTION 5.4.1.  No Adverse Distinction.  Notwithstanding any
other provision of this Agreement, in discharging their respective
responsibilities hereunder, neither NSP, as Project Manager or as
Participant, nor any other Participant shall make any adverse
distinction between Sherco 3 and any other generating unit or common
facilities in which it has an interest solely because of its co-
ownership of Sherco 3 with the other Participants.  Any action or
failure to act by a Participant shall not violate this Section if such
Participant's decision to act, or not to act, was based upon factors
other than its co-ownership of Sherco 3 with the other Participants.

         SECTION 5.4.2.  Cooperation.  The Participants will cooperate
with each other in all activities relating to Sherco 3, including,
without limitation, the execution and filing of applications for
authorizations, permits and licenses and the execution of such other
documents as may be reasonably necessary to carry out the provisions of
this Agreement.  In addition, each Participant agrees, upon the request
of any other Participant, to cooperate with such requesting Participant,
as reasonably necessary and at the requesting Participant's expense, in
the issuance and sale by the requesting Participant of securities to
finance its ownership interest in Sherco 3 and to provide at the
requesting Participant's expense such information, certificates,
opinions and other documentation with respect to the construction and
operation of Sherco 3 and with respect to its business and affairs as
are requested and reasonably necessary in connection with the issuance
and sale of such securities.  Each Participant shall preserve and
protect the confidentiality of any such information or other
documentation specified by the furnishing Participant except to the
extent prevented from doing so by applicable law or except to the extent
that the issuance and sale of its securities requires disclosure
thereof.  Where disclosure of such information or other documentation,
or any part thereof, is required by applicable law or by the issuance
and sale of the requesting Participant's securities, the requesting
Participant shall to the extent practicable promptly notify the
furnishing Participant. prior to such disclosure and give it reasonable
opportunity to present its views on the necessity and form of
disclosure.

         SECTION 5.4.3.  Observers.  From and after the SOUTHERN
MINNESOTA Closing, SOUTHERN MINNESOTA shall have the right to have two
resident observers at the Sherco 3 Site at all times for purposes of
observing and monitoring Sherco 3.  From and after the UNITED MINNESOTA
Closing, UNITED MINNESOTA shall have the right to have one resident
observer at the Sherco 3 Site for the same purpose.

         Such resident observers shall be subject to, and required to
conduct themselves in accordance with, the directives of the Project
Manager's senior site official to the end that their activities shall
not interfere with the Project Manager's performance of its obligations. 
The resident observers shall be reasonably qualified to perform the
duties assigned to them but at no time shall they be permitted to take
any part in nor to give any instructions or orders.

         The resident observers shall have access to all parts of Sherco
3 and, upon request and within a reasonable time to comply or as soon
thereafter as the same are prepared or available to the Project
Manager's employees, shall have access to all records, papers,
documents, reports, and other information concerning Sherco 3.

         The resident observers shall be provided with office space and
furnishings, reasonably necessary to allow them to perform their duties,
as part of the project cost.  All other costs shall be borne by the
Participant the observer represents.

         Each resident observer shall be the employee of SOUTHERN
MINNESOTA or UNITED MINNESOTA, as the case may be, and shall not be the
employee, servant, or agent of NSP.  In addition to the resident
observers, SOUTHERN MINNESOTA and UNITED MINNESOTA each shall be
entitled to have other authorized representatives, including outside
consultants, at reasonable times observe and inspect Sherco 3.  Such
observers, visitors, and representatives shall be subject to, and
required to conduct themselves in accordance with, the directives of the
Project Manager's senior site official to the end that their activities
shall not in any way interfere with the Project Manager's
responsibilities.

         SECTION 5.4.4.  Plant Tours.  Upon prior approval of the Project
Manager, the Participants may schedule plant tours and visits at Sherco
3.

         SECTION 5.4.5.  Settlement of Disputes.  In the event any
dispute between any of the Participants should arise out of or relating
to this Agreement concerning a matter not already delegated by this
Agreement for determination by the Management Committee, such dispute
shall be first submitted to the Management Committee for review and
decision.  The Management Committee shall have thirty days from and
after the date upon which such dispute is submitted to it in which to
resolve such dispute.  Such dispute shall be deemed to be resolved by
the Management Committee if, but only if, said Committee unanimously
arrives at a single determination thereof.  If the Management Committee
is unable to resolve such dispute, then the Participants shall forthwith
submit such dispute to the chief executive officers of the Participants
for review.  Said chief executive officers shall have an additional
thirty days from and after the date upon which such dispute is submitted
to them in which to resolve such dispute.  Said chief executive officers
may resolve such dispute if, but only if, they unanimously arrive at a
single determination thereof.  If such dispute is not so resolved and
the Participants involved in the dispute resort to litigation, the other
Participants shall have the right to intervene in such litigation.

         ARTICLE 5.5.  LIMITATION OF LIABILITY

         SECTION 5.1.  General.  Except to the extent such liability is
discharged by project insurance acquired under Section 3.3.12, the
Project Manager and its directors, officers, agents and employees shall
not be liable to the Participants for any loss, cost, damage or expense
incurred by the Participants as the result of any action or failure to
act, whether negligent or otherwise, by the Project Manager or its
directors, officers, agents or

employees in carrying out the provisions of this Agreement, except for
any such loss, cost, damage or expense which is the result of the
Project Manager's "gross negligence" or "intentional wrongdoing", which
terms are defined as follows:

              (a) "gross negligence" is more than a failure to exercise
         due care under the particular facts and circumstances and is
         more than inadvertence or inattention. "Gross negligence" must
         involve an act or an omission of an aggravated character
         respecting a significant legal duty. Such an act or omission
         amounts to a reckless disregard of such a legal duty or is an
         act or omission that shows, or at least raises a presumption
         of, conscious indifference to such a legal duty;

              (b) "intentional wrongdoing" is any action or failure to
         act by the Project Manager with the intent of using its
         authority as Project Manager to place any Participant at an
         unfair disadvantage in-relation to NSP or any intentional
         violation of a significant obligation to a Participant under
         the provisions of this Agreement.

In the event of its gross negligence or intentional wrongdoing, the
Project Manager shall be liable to the Participants for all direct
damages.  Nothing herein shall prevent any Participant from pursuing an
action for specific performance of the Project Manager's obligations
hereunder after the complaining Participant has sought and been denied
satisfactory relief by the Management Committee.  In no event, however,
shall the Project Manager or any Participant be liable for actions
arising out of this Agreement to a Participant with respect to any
claim, whether based upon contract, tort (including negligence), patent,
trademark or service mark or otherwise, for any indirect or
consequential damages.  Actions of nonmanagement employees of the
Project Manager shall not be imputed to the Project Manager.

         SECTION 5.5.2.  Costs Shared by Participants.  Except to the
extent such liability is discharged by project insurance acquired under
Section 3.3.12, and except as otherwise provided in Section 5.5.1, all
loss, cost, damage and expense incurred or sustained by the Project
Manager in connection with the performance of this Agreement, including
but not limited to (i) workers' compensation liability of the Project
Manager to its employees, (ii) liability to agents, contractors,
subcontractors, consultants and other third parties and (iii) any cost
and expense related to investigating, defending or settling claims of
any Participant or third party (including counsel fees and other costs
of litigation) whether based upon contract, tort (including negligence)
or otherwise, shall be shared by the Participants in proportion to their
respective Ownership Percentages (or, to the extent the liability
relates to Joint Common Facilities, in proportion to their respective
Joint Common Facility Percentages); provided, however, that the Project
Manager shall not settle any claim except in accordance with Section
3.2.3(f) hereof.

         SECTION 5.5.3.  No Liability for Delays or Unavailability.  The
Project Manager shall not be liable to the Participants for any loss,
cost, damage or expense caused by delays in completion or unavailability
of the Sherco 3 Project or by plant shutdowns or service interruptions
except as otherwise provided in Section 5.5.1.

         SECTION 5.5.4.  No Liability for Acts of Other Participants. 
Nothing in this Agreement shall be construed to create joint or several
liability of a Participant for the acts, omissions or obligations of any
other Participant (except as otherwise provided under Chapter Three or
Section 5.5.2 hereof for acts, omissions or obligations of the Project
Manager as agent for the Participants).

         SECTION 5.5.5.  No Guarantee of Final Costs.  The Project
Manager does not guarantee the final cost of construction, operation,
maintenance or decommission of any part of the Sherco 3 Project.  All
oral and written forecasts of costs, construction expenditures and
operating and maintenance expenses are estimates only, subject to change
and final determination at the time the costs are incurred.

         ARTICLE 5.6.  MISCELLANEOUS

         SECTION 5.6.1.  Survival.  The agreements, covenants,
representations and warranties contained herein shall survive the
SOUTHERN MINNESOTA Closing and the UNITED MINNESOTA Closing.

         SECTION 5.6.2.  No Delay.  No disagreement or dispute of any
kind between or among any of the Participants concerning any matter,
including without limitation the amount of any payment due hereunder or
the correctness of any charge made hereunder, shall permit any
Participant to delay or withhold any payment pursuant to this Agreement.

         SECTION 5.6.3.  Further Assurances.  From time to time after the
respective closings hereunder, the Participants will execute and deliver
such instruments of conveyance and other documents, upon the request of
another Participant, as may be necessary or appropriate to carry out the
intent of this Agreement.

         SECTION 5.6.4.  Governing Law.  The validity, interpretation,
and performance of this Agreement shall be governed by the laws of the
State of Minnesota.

         SECTION 5.6.5.  Notices.  Any notice, request, consent or other
communication permitted or required by this Agreement (other than

Participant by notice in writing.

         SECTION 5.6.6.  Article and Section Headings Not to Affect
Meaning.  The descriptive headings of the various Articles and Sections
of this Agreement have been inserted for convenience of reference only
and shall in no way modify or restrict any of the terms or provisions
hereof.

         SECTION 5.6.7.  No Partnership.

              (a) The covenants, obligations and liabilities of the
         Participants shall be several and not joint or collective. Each
         Participant shall be solely and individually responsible for
         its own covenants, obligations and liabilities as herein
         provided.  Neither this Agreement nor any grant, lease or
         license related thereto, shall create any new entity nor be
         construed to create a new entity, such as a partnership,
         association or joint venture.  The Participants shall not be
         liable as partners.  No Participant or group of Participants
         shall be under the control of or be deemed to control any other
         Participant or the Participants as a group.  Except to the
         extent this Agreement confers upon NSP the authority to act as
         agent for and on behalf of the other Participants with respect
         to their several and separate individual interests and
         obligations, no Participant shall have the right or power to
         bind any other Participant.

              (b) The Participants agree that they will take any and all
         action necessary and appropriate to secure exclusion from
         Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue
         Code of 1954, as amended to date or as it may be amended
         hereafter, or under any similar income tax laws.  The
         Participants agree to formally elect, if necessary, under the
         authority of Section 761(a) of the Internal Revenue Code of
         1954, to be excluded from the application of all provisions of
         said Subchapter K.  If the tax laws of the State of Minnesota
         hereafter contain provisions similar to those contained in
         Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue
         Code of 1954 under which a similar election is permitted, the
         Participants agree to exercise such similar election.  NSP is
         hereby authorized to file such evidence as may be necessary to
         give effect to the election made in this Section 5.6.7(b).

         SECTION 5.6.8.  Time of Essence.  Time is of the essence of this
Agreement.

         SECTION 5.6.9.  Successors and Assigns/Binding Obligations.

              (a) Except as otherwise provided in subsection (b) hereof
         all of the respective covenants, undertakings and obligations
         of each of the Participants set forth in this Agreement (i)
         shall apply to and bind all other persons, firms, partnerships,
         corporations or entities claiming by, through or under any of
         the Participants and their successors or assigns; (ii) shall be
         covenants, restrictions and obligations running with each
         Participant's respective interest in the land and all other
         rights, titles and interests in Sherco 3 and with all of the
         rights and interests of each Participant under this Agreement;
         and (iii) shall be for the benefit of the Participants and
         their respective successors and assigns in and to Sherco 3. 
         All such covenants and obligations shall be binding upon any
         entity which acquires any of the rights, titles and interests
         of any Participant in Sherco 3 or in, to and under this
         Agreement, except that in the case of a partial assignment the
         assignee shall only be required to share in the cost of
         fulfilling said covenants and obligations of the assigning
         Participant to an extent proportionate to the interest so
         assigned.

         (b) Any party which acquires the interest of a Participant in
Sherco 3 after the Commercial Operation Date through enforcement of the
default provisions contained in any mortgage or other security agreement
granted by such Participant as authorized by Section 2.3.2(d) hereof
shall not be required to assume or become obligated to perform, or be
liable for, any of the payment obligations of such Participant which
accrued prior to the time that such party acquires such interest nor
shall such party be required to assume or become obligated to perform,
or be liable for, any of the obligations of such Participant which
accrue after such party ceases to have an interest in Sherco 3.  During
the time that such party has an interest in Sherco 3, it shall not be
liable for failure to make any payment hereunder which accrues during
such time, except that the provisions of Section 5.1.6 and Section 5.1.7
hereof shall be applicable in respect of such failure and except that
such party shall be liable for failure to make any payment accruing
during, but not before or after, any period that such party is receiving
Energy from Unit 3 by exercising the rights of such Participant
hereunder, which rights can be exercised without curing such
Participant's defaults. Such a party may convey its interest acquired
from such Participant subject to the provisions of Article 2.3, but free
of any obligation on a purchaser to cure defaults of such Participant
and free of any obligation on such party to hold the other Participants
harmless if the purchaser fails to fulfill its obligations to the other
Participants under this Agreement.

         SECTION 5.6.10.  Counterparts.  This Agreement may be executed
simultaneously in two or more counterparts, each of which shall be
deemed an original but all of which together shall constitute one and
the same instrument.

         SECTION 5.6.11.  Computation of Undivided Ownership Percentage. 
Notwithstanding any other provision of this Agreement, whenever,
pursuant to any provision of this Agreement, any action is required to
be agreed to or taken by the Management Committee, (i) only those
Participants not in default in the payment of any amounts (together with
interest, if appropriate) required under or contemplated by any
provisions of this Agreement at the time such action is to be agreed to
or taken shall have the right to participate in such agreement or the
taking of such action; and (ii) the computation of the Ownership
Percentages of Participants agreeing to or taking any such action shall
be based solely upon the Ownership Percentages of Participants not so
in default and, for such purposes, the Ownership Percentage of a
defaulting Participant shall be allocated to the nondefaulting
Participants in the ratio that each respective nondefaulting
Participant's Ownership Percentage bears to the aggregate Ownership
Percentages of all nondefaulting Participants.

         SECTION 5.6.12.  Descriptions.  As soon as practicable after the
Commercial Operation Date of Sherco 3, the Project Manager shall furnish
to each other Participant descriptions of Sherco 3, setting forth in
reasonable detail the facilities, equipment and other property and
rights then constituting such unit or facilities, including all
property, real or personal, and rights therein jointly paid for under
this Agreement.

         SECTION 5.6.13.  Severability.  In the event that any of the
terms, covenants or conditions of this Agreement or the application of
any such term, covenant or condition shall be held invalid as to any
person or circumstances by any court having jurisdiction in the
premises, the remainder of this Agreement and the application of its
terms, covenants or conditions to such persons or circumstances shall
not be affected thereby but shall remain in force and effect.

         SECTION 5.6.14.  No Third Party Beneficiary.  The Participants
do not intend to create rights in or to grant remedies to any third
party as a beneficiary of this Agreement or of any duty, covenant,
obligation or undertaking established herein except as otherwise
provided in Section 2.3.2 and Section 5.6.9.

         SECTION 5.6.15.  No Implied Waiver.  Any waiver at any time by
the Project Manager or any Participant of its rights with respect to a
default or any other matter arising in connection with this Agreement
shall not be deemed a waiver with respect to any subsequent default or
matter.

         SECTION 5.6.16.  Amendments.  (a) Except for any amendment to
this Agreement or the Exhibits hereto which, pursuant to the terms
hereof, may be made by vote of the Management Committee, no amendment
to this Agreement or the Exhibits hereto shall be effective unless
approved in writing by each Participant hereto.  Whenever an amendment
to this Agreement or any Exhibit hereto is made, in Accordance with this
Agreement, by action of the Management Committee, the Participants shall
ratify such action by duly executing such Amendment.

              (b) In the event any provision of this Agreement is
         determined to be unenforceable under any applicable statute or
         any regulation or order of any regulatory agency having
         jurisdiction, the Management Committee shall direct an
         amendment of this Agreement which is believed to cure such
         provision while at the same time permitting the accomplishment
         of any lawful objective sought to be accomplished by such
         provision.

              (c) It is the intent of the Participants in entering into
         this Agreement not to create restrictions on their respective
         ownership interests in Sherco 3 which will disqualify the use
         of a Participant's ownership interest as collateral for
         financing purposes to the extent permitted by Section 2.3.2(d)
         hereof.  If a Participant demonstrates to the other
         Participants' satisfaction the need for an amendment to qualify
         the Participant's ownership interest as collateral for such
         financing purposes, the Management Committee shall direct the
         adoption of such amendment unless such amendment (i) would be
         prohibited by the terms of, or materially adversely affect the
         interests of holders of indebtedness under, any bond
         resolution, indenture or other debt instrument of any other
         Participant or (ii) would so adversely affect any other
         Participant's ownership interest in Sherco 3 or rights
         hereunder that this Agreement, as amended, would no longer
         reflect an equitable arrangement between the respective
         Participants.

         SECTION 5.6.17.  Term.  This Agreement shall become effective
when it has been duly executed and delivered on behalf of all of the
Participants and shall remain in full force and effect, subject to prior
determination by unanimous agreement by all Participants, until such
time as Sherco 3 is retired from service in accordance with Article 5.3
hereof and all payments associated therewith are made.

         IN WITNESS WHEREOF, the undersigned parties hereto have duly
executed this Agreement as of the date first above written.

EXHIBIT A

                          Brief Description of Unit 3

Unit 3 is a steam electric generating unit to be owned in common by
Northern States Power Company (NSP), Southern Minnesota Municipal Power
Agency and United Minnesota Municipal Power Agency in accordance with
their respective Ownership Percentages as set forth in Section 2.1.1 of
the Agreement.

Unit 3 will be a subbituminous coal-fired steam electric generating unit
with a nominal net generating capacity of 800,000 Kw.  The unit will
have a net heat rate of about 10,300 Btu/Kwh.

The unit will be constructed as an addition to NSP's existing Sherburne
County generating plant located near Becker, Minnesota.  Fuel supplies
for Unit 3 will be delivered by unit trains from mines in Montana and
Wyoming in conjunction with the fuel supplies for Units #l and #2.

Although a more detailed listing of the components of the unit is
provided under the "Description" below, the major components of the unit
can be generally described as follows:

         The boiler will be a Babcock and Wilcox drum-type, balanced
         draft, pulverized coal unit producing 6,100,000 lbs. of steam
         per hour at a pressure of 2520 psi and super heat and reheat
         temperatures of 1,000 degrees F each.  The boiler will utilize dual
         register low nitrous oxide burners.

         The turbine generator, supplied by General Electric Co., will
         include a 3600 rpm, tandem compound, four flow, single reheat
         steam turbine operating at 2520 psi, 1,000 degrees F with 1,000
         degrees F reheat.  The turbine will be equipped for seven stages of
         extraction and employ 33-inch last stage blades.  The generator
         will be rated 950,000 kva, 860,000 Kw, 26,000 v, 0.90 p.f and
         will be hydrogen cooled with a liquid cooled stator conductor.

         The unit will be equipped with three boiler feed pumps (two 50%
         capacity units driven by steam turbines and one 30% capacity
         unit driven by an electric motor) and will employ two forced
         draft and four induced draft fans.

         The flue-gas clean-up system will employ spray dryer absorbers
         for S02 removal and fabric filters for particulate removal. 
         Flue gas will be discharged through a 650 ft. high steel lined,
         concrete shell chimney.  Ash and solids removed from the
         combustion process will be deposited in clay-sealed basins on
         the plant site.

         The unit will have a closed-cycle cooling system employing
         mechanical draft cooling towers and obtaining make-up water
         from the Mississippi River.

         4.  Grantee further covenants that, as provided by Section
         2.1.2(a) of the Ownership Agreement, NSP may at its option
         (which option NSP hereby excepts and reserves unto NSP, its

the Ownership Agreement, payment of certain sums thereunder and other
good and valuable consideration, the receipt and adequacy of which is
hereby acknowledged by NSP, NSP does hereby grant, convey and lease unto
SMMPA those easements, leasehold interests and other rights for the term
and upon.the terms and conditions hereinafter described or set forth:

         1.  Definitions.  Except as expressly provided in this
Instrument, all terms when used herein shall have the meanings specified
in Article 1.1 of the Ownership Agreement.

         2.  Grant of Easement.  NSP hereby conveys and warrants unto
SMMPA a nonexclusive easement in the Sherco Plant Site and the NSP
Common Facilities and in NSP's interest in and to Unit 3, the Joint
Common Facilities and the Future Common Facilities for the purposes set
forth below, but subject to the superior right of NSP to operate,
maintain, repair and reconstruct on the Sherco Plant Site existing
facilities related to Prior Units, provided that any additions to or
enlargements of such facilities are governed by the respective rights
set forth in Section 2.2.4 of the Ownership Agreement.  NSP also
expressly reserves the right to use the Sherco Plant Site for any
purpose which does not unreasonably interfere with the construction or
operation of SMMPA Interests in accordance with Section 2.2.1, but
subject to the respective rights set forth in Section 2.2.4, of the
Ownership Agreement.

         3.  Scope of Easement.  Said easement shall be for the purposes
of access to and construction, reconstruction, maintenance, repair,
operation, and use of all structures and facilities related to Unit 3
located on the Sherco 3 Site and the Sherco Plant Site, including the
Joint Common Facilities, the NSP Common Facilities, and the Future
Common Facilities together with the use of all portions of the Sherco
Plant Site necessary or appropriate to the use and operation of the
SMMPA Interests.  The uses authorized by this paragraph 3 and by
paragraph 10 hereof shall include all rights given to SMMPA under the
Ownership Agreement and all rights necessary or appropriate to exercise
the responsibilities given to the Project Manager in the Ownership
Agreement or reasonably implied therefrom for the use and operation of
SMMPA Interests.  Nothing herein shall be construed as imposing upon
SMMPA any of the obligations of the Project Manager under the Ownership
Agreement.

         4.  Agent.  So long as there is a Project Manager appointed and
acting pursuant to the Ownership Agreement, the rights granted by this
Instrument may be exercised by SMMPA solely through the Project Manager
as agent for SMMPA. As of the date hereof, NSP is the Project Manager
appointed and acting as agent pursuant to the Ownership Agreement, which
Agreement permits, but does not assume there will be, the appointment
of a successor Project Manager.

         5.  Duration.  The easement granted by this Instrument shall
continue in full force and effect until such time, if ever, that Sherco
3 shall be retired pursuant to Section 5.3.1 of the Ownership Agreement,
in which event such easement shall expire when all actions contemplated
by the Ownership Agreement for such retirement shall have been
completed.

         6.   Appurtenant. Such easement shall be deemed appurtenant to
and shall pass with title to SMMPA's undivided ownership interest in the
Sherco 3 Site.

         7.  Improvements.  The parties hereby stipulate and agree that,
for purposes of this Instrument, all facilities now or hereafter
constructed on the Sherco Plant Site or Sherco 3 Site and designated as
Common Facilities are now or shall, upon completion, be deemed to be
fixtures attached to the land subject to this Easement and Lease and
deemed to be "real property".  However, it is expressly agreed that the
ownership of such Common Facilities shall be as determined by the
Ownership Agreement and shall be separate from and not merge with or
otherwise relate to the fee ownership of the land to which such fixtures
are attached.  It is the purpose of this Instrument to grant SMMPA an
easement (or leasehold) interest in the Sherco Plant Site which enables
SMMPA to enjoy its undivided ownership interest or other rights in such
Common Facilities.

         8.  Lease, Term.  To the extent that any of the rights granted
hereby or to the Project Manager under the Ownership Agreement shall be
deemed not to be validly granted by easement and to the extent that any
interest of NSP so encumbered shall be deemed not subject to imposition
of an easement and to the extent that a lease of such interests of NSP
shall create further, greater or superior rights for the benefit of
SMMPA than does an easement, NSP does hereby demise, lease and let unto
SMMPA and SMMPA does hereby hire and take from NSP a non-exclusive
tenancy in the Sherco Plant Site, the NSP Common Facilities and NSP's
interest in and to Unit 3 the Joint Common Facilities and the Future
Common Facilities, to have and to hold the said tenancy for a term
commencing on the date hereof and expiring on the date provided for
expiration of the easement in paragraph 5 hereof.

         9.  Rent.  The rent for such lease term shall be deemed prepaid
in full for the consideration first above recited.

         10.  Conditions of Lease.  The rights and obligations of NSP as
lessor and SMMPA as tenant shall be identical to the rights and
obligations set forth in paragraph 3 above. So long as there is a
Project Manager appointed and acting pursuant to the Ownership
Agreement, SMMPA shall have the right to enter and occupy the premises
leased hereby solely through the Project Manager as agent for SMMPA.

         11.  Partial Release or Limitation.  SMMPA hereby covenants that
for no additional consideration, it shall, from time to time, execute
and deliver instruments, when requested by NSP, releasing, defining or
limiting its rights hereunder as to a specifically described portion or
portions of the Sherco Plant Site in order to facilitate the right of
NSP to convey, lease, transfer any interest therein, encumber, or
otherwise use the Sherco Plant Site for any purpose provided that such
a conveyance, lease, transfer, encumbrance, or use does not unreasonably
interfere with the construction, reconstruction, maintenance, repair,
operation and use of SMMPA Interests.

         IN WITNESS WHEREOF, the parties hereto have executed this
Instrument as of the day and year first above written.

                                   EXHIBIT I

                       ADMINISTRATIVE AND GENERAL COSTS

I.       DIRECT AND INDIRECT COSTS ALLOCATED TO CONSTRUCTION OF SHERCO 3

         A.   Direct Cost Loadings:

              1.  Labor - All labor costs directly charged to Sherco 3
              will be loaded with indirect labor costs such as pensions,
              payroll taxes, insurance and non-productive on a percentage
              basis which fully allocates all indirect labor costs to
              productive labor annually.

              2.  Materials - All material costs directly charged
              to Sherco 3 will be loaded with indirect material such as
              purchasing, warehousing and other indirect material costs
              on a percentage basis with specified maximum dollar amounts
              per invoice and which allocates all indirect material costs
              to projects annually.

         B.   Indirect Cost Loadings:

              1. Engineering and Supervision - Engineering personnel
              (engineers, draftsmen, etc. ) in all the engineering
              departments charge their time to estimate numbers on their
              time cards.  An existing table has a corresponding work
              order number set up for each estimate number.  Therefore,
              the engineering time is translated from E-Number to work
              order number and is charged directly to the project as
              labor.

              Engineering mandays are accumulated by E-Number and
              totalled by engineering department.  The cost of
              supervision and clerical labor and expense are accumulated
              in a series of accounts for each engineering department. 
              The engineering mandays for each department are divided
              into these accounts and a department rate for supervision
              and clerical is determined.  The rate is applied to each
              estimate number on the basis of engineering mandays. 
              Through the translation table, this cost is charged to each
              project work order.

              Contract engineering and drafting services are charged
              directly to the project work order.  If the services are
              not attributable to a specific project, the invoice is
              charged to the department account for supervision and
              clerical and included in the manday rate and spread to that
              department's projects.

              2. Administrative and General - The basis for assigning a
              portion of administrative and general cost to construction
              is as follows. A time study by employee of selected
              administrative departments is conducted annually to
              determine the estimated amount of labor allocable to
              construction.  The actual amount of labor is allocated
              monthly to a clearing account based on this study.  The
              ratio of construction labor to total labor for each of
              these administrative departments is applied to the previous
              years office supplies and expenses of the departments. The
              result is allocated to the clearing account equally over
              twelve months of the current year. The corporate ratio of
              pension and other employee benefits and payroll taxes to
              total labor is applied to the labor amount transferred to
              the clearing account.  The result is also transferred to
              the clearing account.

              Administrative and general expenses are then drawn from the
              clearing account and charged to construction in the ratio
              that administrative and general expense bears to that
              year's Construction Expenditure Forecast.  As the actual
              construction program varies up or down from the forecast,
              so the rate varies inversely.


II.      DIRECT AND INDIRECT COSTS ALLOCATED TO OPERATION OF SHERCO 3


         A.   Operating and maintenance expenses charged to Sherco 3 will
              include loadings to recover A&G expenses consistent with
              Company policy used for all regulatory jurisdictional cost
              studies described as follows:

              1. Labor Additives - All labor costs assigned to Sherco 3
              will be loaded with indirect labor costs such as pensions,
              payroll taxes, insurance and non-productive on a percentage
              ratio which fully allocates all indirect labor costs on the
              basis of the amount of productive labor in operating and
              maintenance expenses charged to Sherco 3 to the total
              electric utility labor.

              2. Materials and Supplies Overhead Expense - All material 
              and supply costs assigned to Sherco 3 will be loaded with
              indirect material costs such as purchasing, warehousing and
              other indirect material costs on a Company experienced
              percentage basis.

              3. General Office Expense Recorded as Administrative and 
              General Expenses - General Office administrative and
              general office salaries, office supplies, outside services
              and other A&G expenses which are determined by an analysis
              to be related to the operating and maintenance of Sherco
              3 will be assigned to Sherco 3 on the basis of productive
              labor in operating and maintenance expense charged to
              Sherco 3 to total electric utility labor.

              4. General Office Expenses Recorded as Production - General 
              Office expenses such as power production, computer
              operations, production training, etc. which are determined
              by an analysis to be related to Sherco 3 will be assigned
              to Sherco 3 on the ratio of Sherco 3 capacity to the total
              NSP system capacity plus the Sherco 3 capacity of Southern
              Minnesota and United Minnesota.

         B.   General Office Fixed Charged on Investment - A charge will
              be made to recover the fixed charges on general and common
              facilities assigned to the production functional use.  This
              charge will include a return on investment, income taxes,
              depreciation, deferred income taxes and property taxes. 
              This charge will be assigned to the production function on
              the basis of labor and be charged on the ratio of Sherco
              3 capacity to the total NSP system capacity plus the Sherco
              3 capacity of Southern Minnesota and United Minnesota.

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.

                                  12

          Where:   500,000 is the capacity sale in kilowatts (Kw).

                   CI is the Capital Investment in $/Kw described herein.

                   LARR is the Levelized Annual Revenue Requirement
                   described herein.

                   Adj is the Adjustment Factor described herein and
                   reflects the fact that the contract term is shorter
                   than the life of Sherco 3.

          4.02  CI will be the Total Installed Cost of NSP's share of
Sherco 3 escalated to May 1, 1993 and divided by the average summer
season Permanent Accredited Generating Capability between 1988 and 1993
of NSP's share of Sherco 3, as demonstrated to the Mid Continent Area
Power Pool or its successor organization.

          4.03  The Total Installed Cost will be the capital costs
associated with Sherco 3 at the time Sherco 3 begins commercial
operation, defined in accordance with the "FERC Uniform System of
Accounts, Electric Plant Instruction #3, Components of Construction
Costs", as modified under the terms of the "Sherburne County Generating
Unit No. 3 Ownership and Operating Agreement" to account for Sherco 3's
portion of the facilities used in common with one or more other
generating units located on the Sherco plant site.

          4.04  The Total Installed Cost shall be escalated to May 1,
1993 using the Handy-Whitman Index of Public Utility Construction Costs
for Fossil Steam Production Plants (identified as Total Steam Production
Plant) in the North Central Region (H-W Index) assuming a uniform daily
escalation rate between reporting dates of the Index. The daily
escalation between January 1, 1993 and May 1, 1993 shall be equal to the
daily escalation between July 1, 1992 and January 1, 1993.  This Total
Installed Cost, except as provided in Section 4.06, shall remain fixed
for the term of this Agreement.

          4.05  In the event Sherco 3 does not begin commercial
operation prior to May 1, 1993, CI shall be $1294/Kw as of January 1,
1988 escalated as above to May 1, 1993.  When Sherco 3 begins commercial
operation, the Total Installed Cost will be de-escalated to May 1, 1993
using the H-W Index to determine the new CI to be used from the date of
commercial operation.

          4.06  In the event additional capital investments are required
on Sherco 3 to meet United States federal regulations, an additional
monthly capacity charge shall be determined using the formula described
in Section 4.01.  Each individual monthly capacity charge shall become
effective one month subsequent to the month that the expenditure is
classified as depreciable property in accordance with the "FERC Uniform
System of Accounts, Electric Plant Instruction #3, Components of
Construction Costs".  If an expenditure is classified prior to May 1,
1993, it shall be escalated from the date it is classified to May 1,
1993 using the procedures described in Section 4.04.  For these
additional capital investments Adj shall be determined based on the life
of the investments considering the difference between the date of Sherco
3 commercial operation and May 1, 1993 and on the Contract Years
remaining at the time the investments are made.

          4.07  LARR shall be defined as:

(Return + Depreciation + Income Taxes - Allowance For
           - Funds Used During Construction)           
- --------------------------------------------------------
Total Investment

LARR shall be determined for each Contract Year using the Cost of
Capital components and formula defined in Schedule 1.

          4.08  Adj shall be determined for each Contract Year using the
following formula:

                       33              12          12
          Adj = (1 + D)   - 1   (1 + D)   - (1 + E)
                ------------- x -------------------
                       12              33          33
                (1 + D)   - 1   (1 + D)   - (1 + E)

          Where:   D is the Cost of Capital as defined in Schedule 1.

                   E is the effective annual escalation rate during the
                   five year period before each Contract Year as
                   determined from the H-W Index, expressed as a percent
                   and divided by 100.

                   33 is the life in years of Sherco 3.

                   12 is the twelve Contract Years.

If D=E, the Adjustment Factor shall be:

                       33                  (12-1)
          Adj = (1 + D)   - 1   12 (1 + E)

                             ENERGY PRICING

          5.01  Manitoba shall bill NSP monthly beginning May 31, 1993,
and NSP shall pay for the energy delivered as follows:

          Monthly Energy Bill = 0.8 x (Fixed Operating Costs + Variable
          Operating Costs).

          Where:   Fixed Operating Costs and Variable Operating Costs
                   are as defined by formula in Schedule 2.

          5.02  Beginning in 1992, on or before December 15 of each
year, NSP shall provide Manitoba an estimate of the Fixed Operating

                   April 30, 1996, April 30, 2000 and April 30, 2004 and
                   3,285,000 Mwh for the other nine Contract Years.

                   A - is the energy delivered to NSP pursuant to
                   Section 2.01 herein during the Contract Year
                   expressed in Mwh.

                   B - is the Variable Operating Costs for the Contract
                   Year as determined in accordance with Schedule 2,
                   divided by the energy delivered, A, to express it in
                   $/Mwh.


          5.06  In accordance with Section 2.02 herein, at the end of
each Contract Year if the delivery of energy scheduled by NSP has been
restricted under Sections 1.04 and/or 1.05 herein, NSP shall bill
Manitoba and Manitoba shall pay the lesser of the following:

                P = C x 1.2 x B + F x 0.8 x B; or

                         L - A
                 1       -----

                         ADVERSE WATER PROVISIONS

          6.01  During the contract period, in the event of adverse
water conditions in MHEB's watershed, NSP shall deliver to Manitoba upon
request a maximum of 1,500,000 Mwh of energy in any twelve month period
to allow Manitoba to fulfill its obligation under this Agreement.

          6.02  This energy shall be that available from generation on
the NSP system after NSP has made provision to supply its firm energy
commitments, including firm sales to other utilities.

          6.03  Manitoba shall pay NSP for the energy delivered an
amount equal to NSP's cost of providing such energy plus the average
percent markup NSP received from energy sales to U.S. utilities during
the previous twelve month period or plus 10% of NSP's cost of providing
such energy, whichever is greater.

                                      By:
                                           Chairman, President and CEO

                                      And

                                           Assistant Secretary


                                      The Manitoba Energy Authority


                                      By:
                                           Chairman


                               SCHEDULE 1

                              (ARTICLE IV)

The Levelized Annual Revenue Requirement (LARR) and the Cost of Capital
(D) shall be calculated at the beginning of each Contract Year and shall
be determined using the definitions and formulas shown below.  LARR and
D shall be expressed as a fraction and rounded to the nearest ten-
thousandth.

              LARR = (1.2689 + 0.1553 (WD + WS) + 0.2748 (WP + WC))2
                     -----------------------------------------------
                                         100

D =       WD + WS + WP + WC
          -----------------
                100

              where:

                     WD = The average weighted cost of long-term debt
                     expressed in percent.

                     WS = The average weighted cost of short-term debt
                     expressed in percent.

                     WP = The average weighted cost of preferred equity
                     expressed in percent.

                     WC = The average weighted cost of common equity
                     expressed in percent.

The weighted costs of long-term debt, short-term debt, preferred stock
and common equity shall be determined based on the cost rates and
capital structure used by the Minnesota Public Utilities Commission
(MPUC) to determine the overall rate of return granted in final orders
with respect to rate of return and capital structure for NSP's Minnesota
electric retail jurisdiction (hereinafter called the MPUC Orders).  MPUC
Orders shall be those Orders effective on May 1 of each Contract Year
and as of May 1 of the preceding four years.  Capitalization ratios
rounded to the nearest ten-thousandth shall be determined using the
following formulas:

          Long-term debt capitalization ratio (CRD) = AD/(AD+AS+AP+AC)
          Short-term debt capitalization ratio (CRS) = AS/(AD+AS+AP+AC)
          Preferred equity capitalization ratio (CRP) = AP/(AD+AS+AP+AC)
          Common equity capitalization ratio (CRC) = AC/(AD+AS+AP+AC)

          where:     AD, AS, AP and AC are, respectively, the dollar 
                     amounts of long-term debt, short-term debt,
                     preferred equity and common equity employed in the
                     MPUC Orders.

The cost rates for long-term debt, short-term debt and preferred equity
used to determine D shall be those approved in the MPUC Orders.  The
cost rate for common equity used to determine D shall be the return on
common equity approved in the MPUC Orders, adjusted to reflect any
difference between the rate base approved in each MPUC Order and the
capitalization corresponding to that rate base.

The following formula shall be used to determine the Common Equity Cost
Rate to be used herein:

              Common Equity Cost Rate (CC) = RAC + (RB-CAP) x
                                             ROR/(CRCxCAP)

              where:

              RAC =  The return on common equity specified in the MPUC
                     Orders expressed in percent.

              RB =   The dollar amount of the rate base approved in the
                     MPUC Orders.

              CAP =  The dollar amount of the capitalization
                     corresponding to the above rate base.  The
                     capitalization used herein will reflect the
                     relationship between rate base and capitalization
                     applicable to the MPUC Order.  Currently, this is
                     equal to rate base less accumulated deferred
                     investment tax credits.

              ROR =  The overall rate of return granted in the MPUC
                     Orders expressed in percent.

              CRC =  The common equity capitalization ratio expressed as
                     a ratio.

In the event the interest deduction used to determine income taxes in
the MPUC Order reflects interest on rate base rather than interest on
capitalization, the following formula shall be used for such years the
Order is in effect to determine the Common Equity Cost Rate to be used
herein:

              Common Equity Cost Rate (CC) = RAC + (RB-CAP) x
                                             (ROR-(WX+WY)xt)/(CRC x CAP)

              where: All terms are obtained from the same MPUC Order and
                     RAC, RB, CAP, ROR and CRC are as described above.

              WX =   The weighted cost of long-term debt approved in the
                     MPUC Order expressed in percent.

              WY =   The weighted cost of short-term debt approved 
                     in the MPUC Order expressed in percent.

              t =    The composite federal and state income tax rate
                     employed in the MPUC Order expressed as a fraction.

The weighted cost of long-term debt as of May 1 of each year shall be
based on the MPUC Order in effect on May 1 of that year and determined
by multiplying the long-term debt capitalization ratio times the long-
term debt cost rate expressed as a percent.  WD for each Contract Year
will be determined by summing the weighted cost of long-term debt as of
May 1 of that Contract Year and as of May 1 of the preceding four years
and dividing that summation by five.

WS, WP and WC shall be determined using the same procedure and using the
respective capitalization ratios and cost rates.

Schedule 2

(ARTICLE V)

Fixed Operating Costs (FOC) = (OC-(VMR x EP) + (CF x  ZNL)) x 500

                                                              MAC

          Where: OC = The monthly Operating Costs and shall include all
          costs and expenses (other than-fuel costs) incurred in respect
          of the management, control, operation and maintenance of
          Sherco 3, including without limitation that portion of
          administrative and general expenses incurred by NSP determined
          to be allocable to Sherco 3.  OC shall consist of all items
          which were properly recordable as a production expense in
          accordance with the United States Federal Energy Regulatory
          Commission (FERC) Uniform System of Accounts as of the date of
          this Agreement. Without limiting the generality of the
          foregoing, OC shall include fixed fuel transportation costs
          (if any), carrying charges associated with the cost of fuel
          required to establish initial inventory on May 1, 1993 and any
          property taxes or payments in lieu thereof levied against
          Sherco 3.

          VMR = The Variable Maintenance Rate expressed in $/Mwh.  The
          Variable Maintenance Rate is $1.325/Mwh in 1984 and shall be
          escalated to the current Contract Year as follows:

              $0.825/Mwh times the ratio of the Cost Index in the
              current Contract Year to the Cost Index in 1984, such Cost
              Index being the Handy-Whitman Index of Public Utility
              Construction Costs for Boiler Plant Equipment-Coal Fired
              in the North Central Region, plus $0.50/Mwh times the
              ratio of the weighted average hourly wage rate in the
              current Contract Year to the weighted average hourly wage
              rate in 1984, as stated in the labor agreement between NSP
              and the International Brotherhood of Electrical Workers or
              any successor agreement.

          The method of determining VMR and its value shall be reviewed
          annually by the Coordinating Committee.

          EP = The monthly production of NSP's share of Sherco 3
          expressed in Mwh.

          CF = Cost of Coal expressed in dollars per million British
          Thermal Units ($/MBTU) as determined below.

          ZNL = The monthly coal consumed expressed in MBTU had Sherco
          3 operated all hours of the month such that NSP's share of the
          Sherco 3 gross output equalled NSP's share of the total
          auxiliary energy consumption (Zero Net Load).

          MAC = The Monthly Accredited Capability expressed in MW of
          NSP's share of Sherco 3.

Variable Operating Costs (VOC) = (FC x CF) + (VMR x MED)

          Where: FC = The Fuel Consumption expressed in MBTU and shall
          be the total monthly coal consumed above ZNL by Sherco 3 had
          Sherco 3 produced energy equal to the energy delivered to NSP
          from Manitoba.  FC shall be determined on an hourly basis and
          shall be the Mwh delivered to NSP from Manitoba multiplied by
          the coal consumed above ZNL, expressed in MBTU/Mwh, had Sherco
          3 been operating at a net output equal to the same percentage
          of its monthly accredited capability as the delivery is of 500
          MW.

          MED = The total monthly energy delivered to NSP by Manitoba
          expressed in Mwh.

          The Cost of Coal (CF) = BC x ESC

          Where: BC = The Base Fuel Cost and shall be the delivered cost
          of the primary coal supply for NSP's share of Sherco 3
          effective May 1, 1993, as reported to FERC expressed in
          $/MBTU.

          ESC = The ratio of the Sherco 3 primary coal price for NSP at
          the point of origin in the current month expressed in $/MBTU
          to that portion of BC which is the Sherco 3 primary coal price
          for NSP at the point of origin effective May 1, 1993.
