ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.


         As previously reported, on September 28, 2000, NorthWestern
Corporation ("NorthWestern"), Touch America Holdings, Inc. and The Montana
Power Company, entered into a Unit Purchase Agreement, which was subsequently
amended on June 21, 2001, pursuant to which NorthWestern agreed to purchase all
of the outstanding units of The Montana Power, L.L.C., which holds the electric
and natural gas utility business of The Montana Power Company. The purchase
of all of the outstanding units of The Montana Power, L.L.C. was completed on
February 15, 2002. The total consideration for the purchase was
$1,090,000,000, which consisted of $602,000,000 in cash and the assumption of
$488,000,000 of existing debt and preferred stock of The Montana Power,
L.L.C., net of cash received.

         NorthWestern financed the acquisition with its new credit agreement,
dated as of January 14, 2002, with Credit Suisse First Boston, ABN AMRO Bank
N.V., CIBC Inc. and Barclays Capital plc, as co-arrangers, Credit Suisse
First Boston, as administrative agent, lead arranger and sole book runner,
and the banks and other financial institutions parties thereto. The new
credit agreement is a $1.0 billion credit facility with a term of 364 days
following the closing of the acquisition. The credit facility consists of a
$280.0 million revolving credit facility and a $720.0 million acquisition
term loan. In connection with the closing of the purchase, NorthWestern drew
$720.0 million of the acquisition term loan and $19.0 million of the
revolving credit facility to finance the cash portion of the purchase price, pay
related transaction expenses and repay borrowings under and terminate our old
credit facility with CIBC Inc. and for working capital purposes.

         A copy of NorthWestern's press release relating to the purchase of The
Montana Power, L.L.C. is attached hereto as Exhibit 99.1. The description

                 SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         On one or more occasions, we may make statements regarding our
assumptions, projections, expectations, intentions or beliefs about future
events.

         Words or phrases such as "anticipates," "believes," "estimates,"
"expects," "intends," "plans," "predicts," "projects," "will likely result,"
"will continue" or similar expressions identify forward-looking statements.

         Forward-looking statements involve risks and uncertainties which
could cause actual results or outcomes to differ materially from those
expressed. We caution that while we make such statements in good faith and we
believe such statements are based on reasonable assumptions, including
without limitation, management's examination of historical operating trends,
data contained in records and other data available from third parties, but
there can be no assurance that our projections will be achieved or
accomplished.

         In addition to other factors and matters discussed elsewhere in our
most recent quarterly and annual reports that we file with the SEC, some
important factors that could cause actual results or outcomes for
NorthWestern to differ materially from those discussed in forward-looking
statements include:

         -  the adverse impact of weather conditions;

         -  unscheduled generation outages;

         -  maintenance or repairs;

         -  unanticipated changes to fossil fuel or gas supply costs or
            availability due to higher demand, shortages, transportation
            problems or other developments;

         -  developments in the federal and state regulatory environment and
            the terms associated with obtaining regulatory approvals;

         -  costs associated with environmental liabilities and compliance
            with the environmental laws;

         -  the rate of growth and economic conditions in our service
            territories and those of our subsidiaries;

         -  the speed and degree to which competition enters the industries
            and markets in which our business operations;

         -  the timing and extent of changes in interest rates and
            fluctuations in energy-related commodity prices;

         -  risks associated with acquisitions, transition and integration of
            acquired companies, including implementation of information
            systems and realizing efficiencies in excess of any related
            restructuring charges;

         -  availability of minority interest basis for loss allocation
            purposes;

         -  our ability to recover transaction costs;

         -  approval of our default supply portfolio by the Montana
            Public Service Commission;

         -  disruptions and adverse effects in the capital market due to
            the changing economic environment;

         -  our credit ratings with Moody's and Standard & Poor's;

         -  changes in customer usage patterns and preferences; and

         -  changing conditions in the economy, capital markets and other
            factors identified from time to time in our filings with the SEC.

         Any forward-looking statement speaks only as of the date on which such
statement is made, and, except as required by law, we undertake no obligation to
update any forward-looking statement to reflect events or circumstances after
the date on which such statement is made or to reflect the occurrence of
unanticipated events. New factors emerge from time to time and it is not
possible for management to predict all such factors, nor can it assess the
impact of any such factor on its business or the extent to which any factor, or
combination of factors, may cause results to differ materially from those
contained in any forward-looking statement.
