NORTHERN BORDER PARTNERS, L.P. REPORTS INCREASED
SECOND QUARTER RESULTS AND RAISES 2004 GUIDANCE

FOR IMMEDIATE RELEASE: Monday, July 26, 2004

         OMAHA - Northern Border Partners, L.P. (NYSE - NBP) today reported
second quarter 2004 income from continuing operations of $33.3 million, or $0.66
per unit, compared to $27.6 million, or $0.56 per unit, in the second quarter
2003. Year-to-date 2004, Northern Border Partners reported income from
continuing operations of $69.9 million, or $1.39 per unit, as compared to $60.9
million, or $1.26 per unit for the same period 2003. Net income for the second
quarter of 2003 included an after-tax gain of $4.9 million, or $0.10 per unit,
from the sale of the Gladys and Mazeppa processing plants, reported in
discontinued operations.

         Cash flows as measured by earnings before interest, taxes, depreciation
and amortization (EBITDA) increased to $87.1 million in the second quarter 2004
from $85.4 million in the second quarter of 2003. Year-to-date 2004 EBITDA was
$178.4 million compared to $172.3 million for the same period one year ago.




         Increased second quarter 2004 results are primarily attributable to
higher prices of both natural gas and natural gas liquids in the Partnership's
Williston Basin gathering and processing business; interest expense reductions
created by decreases in average debt outstanding and average interest rates; and
continued strong performance by the Partnership's interstate pipelines.

         Delivered volumes in the Partnership's interstate natural gas pipelines
segment decreased slightly during second quarter 2004 at 273 billion cubic feet
(Bcf) versus 276 Bcf for the second quarter of 2003. Average gathering volumes
increased to 1,178 million cubic feet per day (MMcf/d) during the second quarter
2004 compared to 1,111 MMcf/d for the second quarter 2003. Volumes on the
Partnership's wholly-owned gathering systems in the Powder River Basin declined
to 204 MMcf/d in the second quarter of 2004 from 212 MMcf/d in second quarter
2003. Gathering and processing volumes in the Williston Basin increased to 56
MMcf/d for the second quarter of 2004 from 52 MMcf/d in the second quarter 2003.

         The Partnership also increased its EBITDA and earnings guidance for
2004, now expecting net income for 2004 to be in the range of $129 million to
$134 million or $2.55 to $2.65 per unit. EBITDA in 2004 is anticipated to be
approximately $344 million to $350 million. Distributable cash flows (DCF) for
2004 are expected to be $183 million to $188 million or $3.70 to $3.80 per unit.

         "We benefited from higher volumes and strong gas and liquids prices in
our processing activities in the Williston Basin this quarter. Our interstate
pipelines also reported increased revenues and net income during this reporting
period despite a small decrease in throughput," said Bill Cordes, chairman and
chief executive officer of Northern Border Partners. "We are therefore pleased
to increase our earnings guidance for this year."

         "We are also excited to announce two organic growth projects currently
under development. First, the Eastern Extension Project on Midwestern Gas
Transmission is in the final stages of approval. Second, is a Bear Paw Energy
natural gas gathering project that has initiated construction activity in the
Bakken Oil Play in the Williston Basin. Together these projects represent more
than $40 million in growth capital expenditures and would contribute to cash
flow beginning in 2005 and 2006," Cordes said.




         On July 20, 2004, the Partnership Policy Committee declared the
Partnership's quarterly cash distribution of $0.80 per common unit for the
second quarter of 2004. The indicated annual rate is $3.20. The distribution is
payable August 13, 2004 to unitholders of record July 30, 2004.

         Northern Border Partners will host a conference call on Tuesday, July
27, 2004 at 9:00 a.m. Central Time to review second quarter 2004 results and
discuss its outlook for the remainder of 2004. This call is being web cast by
CCBN and may be accessed via the Partnership's website at
http://www.northernborderpartners.com.

         An audio replay of the call will be available through August 3, 2004 by
dialing, toll free in the United States and Canada, 800-405-2236 and entering
passcode 11002414.

         The Partnership has disclosed in this press release EBITDA and DCF
amounts that are non-GAAP financial measures. Management believes EBITDA and DCF
provide useful information to investors as a measure of comparability to peer
companies. However, these calculations may vary from company to company, so the
Partnership's computations 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. Reconciliations of second quarter and
year-to-date EBITDA to our net income and cash flows from operating activities
for 2003 and 2004 are included in the financial information with this release.
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 intercompany cash management activity. A
reconciliation of projected EBITDA for 2004 to projected net income and a
computation of projected DCF for 2004 are attached to this release.

         Northern Border Partners, L.P. is a publicly traded partnership formed
to own, operate and acquire a diversified portfolio of energy assets. The
Partnership owns and manages natural gas pipelines and is engaged in the
gathering and processing of natural gas. More information can 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 Western Canadian Sedimentary Basin; our
ability to settle with the Fort Peck Tribes on rights-of-way and tax issues and
to recover the associated costs in pipeline rates; the rate of development, gas
quality, and competitive conditions in gas fields near the Partnership's natural
gas gathering systems in the Powder River and Williston Basins and its
investments in the Powder River and Wind River Basins; regulatory actions and
receipt of expected regulatory clearances; renewal of the coal slurry
transportation contract under favorable terms; competitive conditions in the
overall natural gas and electricity markets; performance of contractual
obligations by the shippers; prices of natural gas and natural gas liquids;
regulation under the Public Utility Holding Company Act of 1935, including the
inability to or a delay in obtaining requisite approvals for activities not
pre-approved or exempted; developments in the voluntary petition for bankruptcy
including Bankruptcy Court approval of the sale of CrossCountry Energy, LLC and
the outcome of Enron's Chapter 11 process; actions by rating agencies; our
ability to renegotiate gathering contracts with producers; our ability to
complete acquisitions or growth projects and their future performance; our
ability to control operating costs; and conditions in the capital markets and
our ability to access the capital markets.
