        THIS PUT OPTION AGREEMENT (this "Agreement") is entered into and made effective as of September 30, 1999 by and among NorthWestern Growth Corporation, a
South Dakota corporation ("NGC" and, along with permitted assignees, "Optionor"), the member named below, a natural person resident in the State of South Dakota (along with permitted assigns,

W I T N E S S E T H:    
  


        WHEREAS, concurrently with the execution of this Agreement, Optionee is acquiring an ownership interest (the "Interest") in the Company which will entitle
Optionee to receive from the Company specified distributions and allocations of income, gain, loss, deduction and/or credit (or items thereof) ("Allocations," which for all purposes herein shall
include all Allocations to which Optionee is or may become entitled by virtue of ownership or transfer of the Interest); 



        WHEREAS,
the Company maintains a Targeted Capital Account (as defined in the Limited Liability Company Agreement, dated of even date herewith, of the Company (the "LLC Agreement")) in
respect of the Interest, such Targeted Capital Account consisting of (in addition to Optionee's original capital contribution to the Company) an Acquisition Return Component, an Annual Appreciation
Component and an Equity Ownership Component (each as defined in the LLC Agreement); and 


        WHEREAS,
the Parties desire to set forth their agreement whereby Optionee may from time to time sell all or part of the Interest to Optionor on the terms and subject to the conditions
contained herein; and 


        WHEREAS,
NGC is the Managing Member and controlling person of the Company, and it is in NGC's interest and to its advantage to restrict the transferability of Interests in the Company so

        2.    Purchase Price.    The purchase price for that portion of the Interest which is the subject of an Option shall
be equal to the Fair Market Value of the Interest (or relevant portion thereof) as represented by the positive balances in the various components of the Optionee's Targeted Capital Account determined
in accordance with the procedures set forth in Exhibit A (Acquisition Return Component),  Exhibit B (Annual Appreciation Component), and
Exhibit C (Equity Ownership Component), as
applicable. The purchase price shall be payable in cash, but may, upon the mutual agreement of the parties, be paid in (i) NOR Common Stock or (ii) any combination of cash and NOR Common
Stock. If any portion of the purchase price is to be paid in NOR Common Stock, Optionee shall receive that number of shares of NOR Common Stock which is derived by dividing the portion of the purchase
price to be paid in NOR Common Stock by the average, volume weighted closing price of NOR Common Stock on the New York Stock Exchange for the twenty (20) trading days ending on the date
preceding the date of exercise of the Option. 


        3.    Exercise.


        (a)    Optionee
shall exercise an Option by delivering written notice to Optionor which specifies the portion of the Interest desired to be sold, provided, that in the event
Optionee's employment with NOR, NGC or their affiliates terminates for any reason, each Option which is currently exercisable according to its terms (including by acceleration, if applicable) on the
date Optionee's employment is terminated shall be deemed automatically exercised without further action on the part of any party, provided, however, if Optionee should terminate employment with NGC in
order to be employed by a NOR affiliate, it shall not constitute such automatic exercise. 


        (b)    Upon
delivery (or deemed delivery) of the notice required by Section 3(a), Optionee shall be obligated to sell, and Optionor obligated to purchase, that portion
of the Interest as set forth in the notice for the price and on the terms as set forth in the notice (or deemed notice), and Optionor and Optionee shall take all actions as necessary to complete such
sale. 


        4.    Termination.    This Agreement shall terminate upon the liquidation, dissolution and winding up of the Company. 


        5.    Closing.    The closing (the "Closing") of each purchase transaction contemplated herein shall occur on the
fifth business day following delivery of the notice specified in Section 3. At the Closing, Optionee and Optionor shall each deliver to the other an executed Assignment Agreement, in the form
of  Exhibit E hereto, and Optionor shall deliver the Purchase Price to Optionee. Optionor shall pay all transfer taxes (if any) imposed by reason of
an exercise of an Option. 


        6.    Transfer of Option.    No Party shall have the right to assign, transfer, sell or otherwise encumber such
Party's right, title or interest in or to this Agreement without the written consent and approval of the other Parties hereto, which consent may be withheld in the sole and absolute discretion of any
such Party. Notwithstanding the foregoing, (i) Optionor may assign, transfer, sell or otherwise transfer any of its rights or obligations under or to this Agreement to any affiliate and
(ii) Optionee's rights and obligations under or to this Agreement shall be transferable to Optionee's estate in the event of his or her death or to Optionee's personal representative in the
event Optionee suffers a permanent disability (as defined in the Employment Agreement) or to members of Optionee's immediate family or a trust of which only members of such immediate family are the
beneficiaries. 


        7.    Amendment of LLC Agreement.    Upon the exercise of any Option pursuant to the terms of this Agreement, the
Company hereby agrees to cause the LLC Agreement to be amended to reflect the sale and purchase of the Interest and to take such further action as is necessary and appropriate to effect the sale and
acquisition of the Interest (including, without limitation, the making of any required determinations under Section 3.2(c) of the LLC Agreement in connection with the Transfer of any Interest). 


4





 



        8.    Severability.    Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall endeavor in good faith negotiations to replace any such prohibited or
unenforceable provision with one or more provisions that faithfully reflect the original economic intent of the parties as manifested in the unenforceable provision(s). 


        9.    Arbitration.    To the fullest extent permitted by law, any dispute, controversy or claim arising out of or
relating to this Agreement or the breach or alleged breach of this Agreement, shall be settled by arbitration in Sioux Falls, South Dakota (or, if applicable law requires some other forum, then such
other forum) in accordance with the rules then obtaining of the American Arbitration Association. If the parties to any such controversy are unable to agree upon a neutral arbitration or arbitrators,
then an arbitrator shall be appointed in accordance with such rules. The parties consent to the nonexclusive jurisdiction of the United States District Court for the District of South Dakota, for all
purposes in connection with any such arbitration. The parties agree that any process or notice of motion or other application to either of such courts, and any paper in connection with any such
arbitration, may be served by certified mail, return receipt requested, or by personal service or in such other manner as may be permissible under the rules of the applicable court or arbitration
tribunal, provided a reasonable time for appearance is allowed. All costs of any such arbitration shall be paid by Optionor. 


        10.    Miscellaneous.


        (a)    The
Parties agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. 


        (b)    Subject
to the restrictions of Section 6, this Agreement shall inure to the benefit of, and be binding upon, the successors and assigns of the Parties. No waiver
of any Party's rights hereunder or of any breach or condition of this Agreement shall be deemed to be a waiver of any other or subsequent rights, breach or condition, whether of a like or different
nature. 


        (c)    The
acknowledgements, covenants, agreements and obligations hereunder of each of the Parties hereto shall survive until satisfied in full. 


        (d)    This
Agreement shall be governed by and construed in accordance with the laws of the State of Delaware. 


        (e)    No
modification of this Agreement shall be valid unless made in writing and signed by each of the Parties hereto. 


        (f)    Any
notice provided hereunder shall be so given as set forth in the LLC Agreement. 


        (g)    This

and negotiations are merged herein. 


        (h)    The
parties agree to execute and deliver all such further instruments and to take such further actions as may be reasonably necessary or appropriate to carry out the
intent of this Agreement.

EXHIBIT A    
  


 
 

Criteria For Determining Fair Market Value of
  Acquisition Return Component of Targeted Capital Accounts    
  


        The Acquisition Return Component of each Member's Targeted Capital Account shall be credited with their share of the appreciation (if any) in the Fair Market
Value of an Interest attributable to the "Acquisition Return" realized from each acquisition or investment ("Acquisition") and shall generally be determined as described below. There shall be a
separate Acquisition Return Component maintained for each Investment Strategy and determinations with respect to Acquisitions within one Investment Strategy shall not affect the determinations with
respect to any other Investment Strategy. 


        The
Acquisition Return Component of the Member's Targeted Capital Account shall equal the following percentage(s) of the appreciation (if any) in the Fair Market Value realized from each
acquisition as measured by the actual performance of the Acquisition transactions. 



	 	 	Acquisition Return
	Measurement

Member
	 	Percentage

	Date                	 	 





        The actual amount credited to the Acquisition Return Component of a Member's Targeted Capital Account shall equal the Acquisition Return Percentage (specified
above) times the average purchase price EBITDA multiple paid for the Acquisitions under review times the
EBITDA of the acquired companies used in computing this multiple times the actual EBITDA of these acquisitions during the 12 month period
following the Acquisition as a percentage of their Target EBITDA (see below for definitions and qualifications). 



        Measurement Period:    The 12 month period ending no earlier (unless accelerated) than 12 months after the
month-end following the date of the Acquisition and ending no later than 24 months following the quarter-end most closely following the date of the Acquisition
("Measurement Period"—See also "Make Whole," below). Each Acquisition will be originally evaluated for the period of time that ends
12 months after the month end in which the Acquisition was made (e.g., if an Acquisition was made October 7th, 1998, the measuring period is the 12 months ending
October 31st, 1999), each such Acquisition being an "Eligible Acquisitions". In the event the Actual Performance (in all cases, before general allocations of corporate overhead
and compensation) is less than 95% of Target Performance for the quarter's Eligible Acquisitions, the Measurement Period shall be extended to the end of the following quarter and the results
recalculated. In the event a shortfall remains, the Measurement Period will be extended to each succeeding quarter but can not be extended beyond four quarters from the quarter in which the Eligible
Acquisitions were originally measured for the Acquisition Return Component (e.g., the acquisition made on October 7th, 1998 cannot have a Measurement Period extending beyond the
quarter ending December 31, 2000). 


        In
the event the Actual Performance is more than 105% of Target Performance, the Acquisition Return credited to the Acquisition Return Component of the Member's Targeted Capital Account
will be computed assuming 105% performance. 


        Measurement Criteria:    When an Acquisition requires NOR or NGC Board approval, a "Target Performance" (before allocations of
corporate overhead) is set forth and documented in the acquisition analysis presented to the applicable Board. In the case of Blue Dot Services, Inc. ("Blue Dot") and Exp@nets, Inc.
("Expanets"), the Target Performance for each acquired subsidiary is as set forth in the operating subsidiary's global model. The Acquisition will be evaluated by measuring the Acquisition's Actual
Performance (as reflected in NorthWestern's internal accounting records) during the Measurement Period against Target Performance. 



        Quarterly Aggregate Structure:    All Acquisitions at an operating subsidiary whose Measurement Period ends during a calendar
quarter shall be aggregated for purposes of measuring acquisition return eligibility ("Performance") (e.g., if the Measurement Period for three acquired companies each end in 





 




the fourth quarter of 1998 and each company's Target EBITDA is $1,000,000, the three companies' actual EBITDA for the Measurement Period shall be combined and compared to $3,000,000 (3 companies at
$1,000,000 each) to determine acquisition return eligibility). Acquisitions at different operating subsidiaries shall not be combined (i.e., Blue Dot is grouped separately from Exp@nets). 


        Service Partner/Tuck-in Acquisitions:    Companies that are combined with another company in the same geographic
territory will be tracked and measured separately if the accounting records are kept in such a manner. In the event the accounting records do not allow for separate measurement of a service
partner/tuck-in acquisition (an "Integrated Acquisition"), each Integrated Acquisition with total consideration of $500,000 or less will be measured and credited with the platform company
("Platform") (e.g., if the Platform was purchased on October 7th, 1998 with a Target EBITDA of $200,000 and the tuck-in was acquired on June 30th,
1999 for consideration less than $500,000 with a Target EBITDA of $50,000 and the accounting records do not allow for separate measurement of the tuck-in, the Platform's and the
tuck-in's Target EBITDA will be aggregated and measured on October 31st, 1999 with a Target EBITDA of $216,667 ($200,000 plus $50,000 times 4/12)), the
acquisition return for both the Platform and the Integrated Acquisition being paid at such time. In the event the accounting records do not allow for separate measurement of an Integrated Acquisition
with purchase price consideration greater than $500,000, each Integrated Acquisition will be measured for performance during its Measurement Period by combining the results of the Integrated
Acquisition(s) and the Platform within the common geographic territory. For example, if a Platform acquisition is completed November 15th, 1998 with a Target EBITDA of $200,000
and a tuck-in is completed in the same market on August 15th, 1999 for consideration greater than $500,000 with a Target EBITDA of $50,000 and the accounting records
do not allow for the separate measurement of each organization, the performance of the November 15th Platform acquisition will be measured for the 12 months ending
November 30th, 1999 using a Target EBITDA of $214,833 ($200,000 plus $50,000 times 3.5 months divided by 12 months). The Integrated Acquisition will be measured for
the 12 months ended August 30th, 2000 with a Target EBITDA of $250,000 ($50,000 plus $200,000 times 12/12). 


        Allocation/Credit Frequency:    Determinations and allocations in respect of Acquisition Return Component of the Member's
Targeted Capital Account shall be made quarterly, thirty days following the end of the calendar quarter (or at such other times as called for in the Agreement). 


        Make Whole:    Upon the sale, transfer or disposition of the assets or business of any Acquisition (including, without
limitation, by way of a merger, consolidation, joint venture, public offering, or creation or sale of a minority interest (other than in connection with acquisitions by NGC or its affiliates in the
ordinary course of business consistent with past practices)), the acquisition return on each such Acquisition will be determined and credited to the Acquisition Return Component of the Member's
Targeted Capital Account as though the Acquisition has achieved Target Performance. 



        In
addition, annually, at the end of each fiscal year, all Eligible Acquisitions whose original Measurement Period ended during such fiscal year ("Make Whole Eligible Acquisitions")
shall be eligible for remeasurement in the event any such Make Whole Eligible Acquisitions did not meet Target Performance during the fiscal year. The remeasurement shall be the aggregate purchase
price EBITDA multiple (EBITDA at the end of the fiscal year divided by the purchase price for all Make Whole Eligible Acquisitions) versus the purchase price to EBITDA multiple approved by the NOR or
NGC Board for the Investment Strategy. In the event this aggregate measurement results in a purchase price multiple less than or equal to the Board approved multiple, the 95% minimum Target
Performance criteria shall be lowered to 70% for purposes of computing the acquisition return earned on all Make Whole Eligible Acquisitions. Again, acquisitions at different operating subsidiaries
shall not be combined (e.g., Blue Dot is grouped separately from Exp@nets).

EXHIBIT B    
  


 
 

Criteria For Determining Fair Market Value of
  Annual Appreciation Component of Targeted Capital Accounts    
  


        The Annual Appreciation Component of each Member's Targeted Capital Account shall be credited with their share of the annual appreciation (if any) in the Fair
Market Value of an Interest realized from increases in value attributable to the improved economic performance of investment strategies and businesses for the relevant period (without reference to
determinations made with respect to any prior period) as measured by increases (if any) in the annual after-tax investment returns of such investments and businesses. 


Non-Propane Businesses:  


        The "Improved Return Amount" for non-propane businesses shall equal the amount of investment book earnings,including income from preferred stock or
debt investments in portfolio companies (adjusted as appropriate to reflect income or loss attributable to common stock), and realized capital gains, less fully allocated NGC compensation and overhead
expenses (excluding general allocations of NorthWestern corporate overhead and compensation), over the weighted average annual after-tax return (as adjusted quarterly) of NorthWestern's
utility preferred stock portfolio (the "Preferred Stock Rate"). 


Propane Businesses:  


        The "Improved Return Amount" for propane businesses shall equal the greater of 50% of the cash investment return or total investment book earnings and realized
capital gains, less fully allocated NGC compensation and overhead expenses (excluding general allocations of NorthWestern corporate overhead and compensation), over the Preferred Stock Rate. 



        The
Annual Appreciation Component of each Member's Targeted Capital Account shall be credited with an amount equal to the percentage set forth below of the total Improved Return Amount
for non-propane and propane businesses. 



	 
	 	Private Equity Value as a Percent

of Total Improved Return Amount

	Strategy
	 	Preferred Stock Rate to 10%
	 	10-13%
	 	13+% Return

	New Strategies (post 1/1/99)	 	 	 	 	 	 
	

	All Strategies—From 4/1/00	 	 	 	 	 	 









 
 

EXHIBIT C    
  


 
 

Criteria For Determining Fair Market Value of
  Equity Ownership Component of Targeted Capital Accounts    
  


        The Equity Ownership Component of each Member's Targeted Capital Account shall be credited with their share as set forth below of the "improved equity value" (if
any) of each acquisition and/or investment strategy or portfolio entity ("Investment Strategy") entered into or made or acquired by or on behalf of NGC or any affiliate. There shall be a separate
Equity Ownership Component maintained for each Investment Strategy and determinations with respect to one Investment Strategy shall not affect the determinations with respect to any other Investment
Strategy. 


        The
term "improved equity value" ("IEV"), which shall be determined at such times as required under the Agreement, shall equal: 


IEV =
Portfolio Appraised Value-Portfolio Benchmark Investment Value 



 Where:  




        "Liquidity Date" shall mean the date of determination in accordance with the Agreement (including, without limitation, determinations pursuant to
Section 3.2(c) thereof). 


        "Portfolio
Appraised Value" shall equal the after tax fair market value of the equity in each Investment Strategy at the Liquidity Date as mutually agreed by the Managing Member with the
Approval of the Non-Managing Members (or failing agreement within thirty (30) days, as determined (before general allocations of NorthWestern and NGC corporate overhead and
compensation) without a discount for minority interest, lack of liquidity or other factor by a nationally recognized investment banking firm reasonably acceptable to the Managing Members with the
Approval of the Non-Managing Members and at the cost of the Managing Member). 


        "Portfolio
Benchmark Investment Value" shall equal an amount at the Liquidity Date which is calculated as follows: 


IF
X (1 + (PSIR X PI)) 



 Where:  




        IF = The dollar amount of the Investment Funds actually advanced by or on behalf of NGC or its affiliate(s) in connection with such Investment Strategy. 


        PSIR =
The rate of return on NorthWestern's Preferred Stock Investment Portfolio, stated as a weighted annualized rate over the relevant period, prorated on a daily basis based on
a 365 day year for any partial year. 


        PI =
The period of time such Investment Funds were actually invested in the Investment Strategy (net of any returns, recoveries or distributions in respect of such funds) stated
in years, prorated on a daily basis based on a 365 day year for any partial year and ending on the Liquidity Date. 





 



Long-Term Private Equity Ownership  



        The Equity Ownership Component of each Member's Targeted Capital Account shall be credited with an amount equal to the percentage set forth below of the "Improved
Equity Value" of each Investment Strategy as of the Liquidity Date. 



	 
	 	 
	 	Percent of Improved Return Amount

	Investment Strategy
 
	 	NorthWestern Benchmark

	Note:	(1) The NorthWestern Benchmark Date (NBD) shall be the later of (i) the Approval Date (which is the earlier of the date on which the strategic decision to enter into the particular industry segment was made by the
NorthWestern or NGC Board of Directors, as the case may be, or the date of the closing of the original acquisition or investment in such industry segment) or (ii) the date the Member first became entitled to participate in the equity
appreciation of such Investment Strategy.
