NORTHERN BORDER PARTNERS REPORTS INCREASED
FIRST QUARTER RESULTS

FOR IMMEDIATE RELEASE:  Tuesday, April 22, 2003

         OMAHA - Northern Border Partners, L.P. (NYSE - NBP) reports first
quarter 2003 net income of $32.7 million or $0.69 per unit compared to $28.0
million or $0.62 per unit in the first quarter 2002. Earnings before interest,
taxes, depreciation and amortization (EBITDA) increased from $79.0 million in
the first quarter of 2002 to $86.9 million in the first quarter 2003.

         First quarter 2003 net income reflects a charge of approximately
$600,000 or $0.01 per unit for the cumulative effect of the Partnership's
required implementation of Statement of Financial Accounting Standards (SFAS)
No. 143 "Accounting for Asset Retirement Obligations". SFAS No. 143 requires
entities to record on a present value basis, a liability for asset retirement
obligations, if the liability can be reasonably estimated.

         First quarter 2003 earnings also includes $2.9 million ($0.07 per unit)
resulting from a retroactive cash distribution and special income allocation for
the prior year from the Partnership's interest in a Powder River Basin gathering
system. This distribution, determined in accordance with a joint venture
agreement, was based on the number of wells connected to the gathering system in
the preceding year. If certain targets are not met, Northern Border Partners
receives a disproportionate share of cash distributions.

         Delivered volumes in the Partnership's interstate natural gas pipelines
segment increased during first quarter 2003 to 280 billion cubic feet (Bcf) from
226 Bcf for the first quarter of 2002. Average gathering volumes increased to
1,153 million cubic feet per day (MMcf/d) during the first quarter 2003 compared
to 995 MMcf/d for the first quarter 2002. Processing volumes



were 130 MMcf/d for the first quarter of 2003 compared to 126 MMcf/d for the
first quarter 2002.

         "Overall earnings and cash flow were up for the quarter, compared to
the same time period a year ago," said Bill Cordes, chairman and chief executive
officer of Northern Border Partners. "The interstate pipelines' results include
Viking Gas Transmission for the first time following our acquisition of this
system early this year. Strong commodity prices and the Powder River Basin
special income allocation were the primary drivers for the gathering and
processing segment's higher results."

         The Partnership reiterated that for the full year 2003, it expects
earnings per unit in the range of $2.55 to $2.65 per unit.

         Northern Border Partners will host a conference call to review first
quarter 2003 results on Tuesday, April 22, 2003 at 10:00 a.m. Eastern time.
Interested parties may listen via the Internet live or on a replay basis through
the Partnership's website at http://www.northernborderpartners.com. The call
will also be archived through June 30, 2003 on Northern Border Partners'
website.

         A replay of the call will be available through April 29, 2003 by
dialing, toll free in the United States and Canada, 800-642-1687 and entering
the conference ID number 9543009.

         The Partnership has disclosed EBITDA amounts in this press release.
These amounts are non-GAAP financial measures. Management believes EBITDA
provides useful information to investors as a measure of comparability to peer
companies. However, EBITDA calculations may vary slightly from company to
company, so the Partnership's computation of EBITDA may not be comparable to
other companies. Management further uses EBITDA to compare the financial
performance of its segments and to internally manage those business segments. On
a consolidated basis, EBITDA is reconciled to cash flows from operating
activities determined under GAAP. For segment information of this press release,
EBITDA is reconciled to net income rather than to cash flows from operating
activities, since the Partnership does not determine segment cash flows from
operating activities due to its inter-company cash management activity.

         Northern Border Partners, L.P., a leading transporter of natural gas,
owns interests in four interstate natural gas pipeline systems: a 70 percent
general partner interest in Northern Border Pipeline Company; Midwestern Gas
Transmission Company; Viking Gas Transmission Company; and one-third interest in
Guardian Pipeline, L.L.C. The Partnership also has gathering




systems and processing plants in the Powder River, Wind River and Williston
Basins in the U.S.; owns and operates processing plants and gathering pipelines
in Alberta, Canada; and transports coal-water slurry via a pipeline in the
southwestern U.S. Northern Border Partners, L.P. information may be found at

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 natural gas development in the Powder River, Wind River, Williston and
Western Canadian Sedimentary Basins; regulatory actions and receipt of expected
regulatory clearances; competitive conditions in the overall natural gas and
electricity markets; our ability to market pipeline capacity on favorable terms;
prices of natural gas and natural gas liquids; developments in the voluntary
petition for bankruptcy including Enron's announced intention to form PipeCo of
which Northern Plains and Pan Border would be a part; potential regulation under
Public Utilities Holding Company Act; and conditions in the capital markets and
our ability to access the capital markets.

(1)   EBITDA is computed from (a) net income plus (b) the cumulative effect of
      change in accounting principle; (c) minority interest; (d) interest
      expense, net; (e) income taxes; and (f) depreciation and amortization less
      (g) equity AFUDC.

(2)   Interstate Natural Gas Pipelines' capital expenditures reflect the
      Partnership's 70% ownership of Northern Border Pipeline. Management
      classifies expenditures that are expected to generate additional revenues
      or significant operating efficiency as growth capital expenditures and
      equity investments. Any remaining capital expenditures are classified as
      maintenance.
