NORTHERN BORDER PARTNERS, L.P. REVISES
INITIALLY RELEASED 2001 NET INCOME

FOR IMMEDIATE RELEASE: Monday, March 11, 2002

         OMAHA - Northern Border Partners, L.P. (NYSE - NBP) today announced it
is revising its initially released fourth quarter and full year 2001 net income
to $20.3 million or $0.45 per unit, and $87.8 million or $2.12 per unit,
respectively. The revision relates to noncash adjustments in accounting for
certain commodity hedges of Bear Paw Energy, the Partnership's U.S. gathering
and processing segment.

         In 2001 Bear Paw Energy entered into swap agreements with Enron North
America (ENA), a subsidiary of Enron Corp., to hedge a portion of its share of
the natural gas and natural gas liquids expected to be received as processing
fees in 2001 to 2005. During the fourth quarter of 2001, the hedging
relationships were discontinued due to concerns over the liquidity of ENA.
Previously, the Partnership believed that the change in the market value of the
swaps due to the ENA bankruptcy would result in a reduction in future income
recognition over the term of the swaps. However, under generally accepted
accounting principles, income from these agreements will continue to be
recognized over their original term and the $5.3 million loss in the value of
the hedge will be charged to net income in 2001.

         "The rules regarding accounting for these financial instruments are
complex and evolving," said Bill Cordes, chairman and chief executive officer of
Northern Border Partners. "This does not change the estimate of our exposure to
ENA, which has been fully reserved to-date. The overall effect of this revision
is to move $5.3 million of income from 2001 or $0.12 per unit to the years 2002
through 2005, with just over $4.6 million related to the year 2002. Cash flow is
not impacted. It is also important to note this is a change in the preliminary
earnings information released in January only and not a restatement of financial
statements previously filed with the SEC. We continue to expect to file our Form
10-K on a timely basis."

         Northern Border Partners will host an analyst conference call to
discuss this revision on Tuesday, March 12, 2002 at 8:30 am EST. The Partnership
will also simulcast the call live via the Internet at
http://www.northernborderpartners.com.



         A replay of the call will be available through Tuesday, March 19, 2002
by dialing, toll free, (888) 203-1112 and entering confirmation code 759631. The
call will also be archived on the Northern Border Partners' website.

       Northern Border Partners, L.P. owns a 70 percent general partner interest
in Northern Border Pipeline Company, which owns a 1,249-mile interstate pipeline
system that transports natural gas from the Montana-Saskatchewan border to
markets in the Midwestern United States. Additionally, the Partnership owns the
350-mile long Midwestern Gas Transmission system, which stretches from Portland,
Tennessee to Joliet, Illinois. The Partnership also has gathering systems and

This press release includes forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. Although Northern Border Partners, L.P. believes that its
expectations are based on reasonable assumptions, it can give no assurance that
such expectations will be achieved. Important factors that could cause actual
results to differ materially from those in the forward-looking statements
include developments in the voluntary petitions for bankruptcy by Enron; natural
gas developments in the Powder River, Wind River, Williston and Western Canadian
Sedimentary Basins; regulatory actions; competitive conditions in the overall
natural gas and electricity markets; prices of natural gas and natural gas
liquids; and conditions in the capital markets.
