EXPLANATORY NOTE:

Northern Border Partners, L.P. files this amended report to correct one
typographical error in a report on Form 8-K filed with the Commission on May 20,
2005. In the interest of clarity, this amended report amends and restates in its
entirety that previously filed report. The previously filed report incorrectly
described the Northern Border Pipeline Company Revolving Credit Agreement as a
"$200 million Revolving Credit Agreement," when the Northern Border Pipeline
Company Revolving Credit Agreement should be described as a "$175 million
Revolving Credit Agreement."

ITEM 1.01   ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Effective May 16, 2005, we entered into a $500 million Revolving Credit
Agreement with the lenders named therein and with SunTrust Bank, as
Administrative Agent; Wachovia Bank, National Association, as Syndication Agent;
Harris Nesbit Financing, Inc., Barclays Bank PLC, and Citibank, N.A. as
Co-Documentation Agents; and SunTrust Capital Markets, Inc. and Wachovia Capital
Markets, LLC as Co-Lead Arrangers and Book Managers (the "NBP Credit
Agreement"). $186 million in borrowings are currently outstanding under the NBP
Credit Agreement, which funds were used to pay down the entire amount
outstanding under our $275 Revolving Credit Agreement, which has been
terminated. The interest rate applied to amounts outstanding under the NBP
Credit Agreement may, at our option, be either the lender's base rate or an
adjusted London Interbank Offered Rate plus a spread that is based upon our
long-term unsecured debt ratings. The term of the agreement is five years.

Under the NBP Credit Agreement, we are required to comply with certain
financial, operational and legal covenants. Among other things, we are required
to maintain ratios of EBITDA (net income plus minority interests in net income,
interest expense, income taxes and depreciation and amortization) to interest
expense of greater than 3 to 1. We are also required to maintain a ratio of
indebtedness to EBITDA of no more than 4.75 to 1. If we consummate one or more
acquisitions in which the aggregate purchase price is $25 million or more, the
allowable ratio of indebtedness to adjusted EBITDA is temporarily increased to
5.25 to 1. Upon any breach of these covenants, amounts outstanding under the NBP
Credit Agreement may become immediately due and payable.

The description of the NBP Credit Agreement set forth under this Item 1.01 is
qualified in its entirety by reference to the complete terms and conditions of
the Credit Agreement itself, which is filed as Exhibit 10.1 hereto.

In addition, effective May 16, 2005, Northern Border Pipeline Company, our
indirect, 70% owned subsidiary ("Northern Border Pipeline"), entered into a $175
million Revolving Credit Agreement with the lenders named therein and with
Wachovia Bank, National Association, as Administrative Agent, SunTrust Bank, as
Syndication Agent, Harris Nesbit Financing, Inc., Barclays Bank PLC, and
Citibank, N.A. as Co-Documentation Agents; and Wachovia Capital Markets, LLC and
SunTrust Capital Markets, Inc. as Co-Lead Arrangers and Book Managers ( the
"NBPL Credit Agreement"). As of May 16, 2005, $29 million in borrowings were
outstanding under the NBPL Credit Agreement, which funds were used to pay down
the entire amount outstanding under Northern Border Pipeline's $175 Revolving
Credit Agreement, which has terminated under its own terms. The interest rate
applied to amounts outstanding under the NBPL Credit Agreement may, at Northern
Border Pipeline's option, be either the lender's base rate or an adjusted London
Interbank Offered Rate plus a spread that is based upon Northern Border
Pipeline's long-term unsecured debt ratings. The term of the agreement is five
years.

Under the NBPL Credit Agreement, Northern Border Pipeline is required to comply
with certain financial, operational and legal covenants. Among other things,
Northern Border Pipeline is required to maintain ratios of EBITDA (net income
plus minority interests in net income, interest expense, income taxes and
depreciation and amortization) to interest expense of greater than 3 to 1.
Northern Border Pipeline is also required to maintain a ratio of indebtedness to
EBITDA of no more than 4.50 to 1. If Northern Border Pipeline consummates one or
more acquisitions in which the aggregate purchase price is $25 million or



more, the allowable ratio of indebtedness to adjusted EBITDA is temporarily
increased to 5 to 1. Upon any breach of these covenants, amounts outstanding
under the NBPL Credit Agreement may become immediately due and payable.

The description of the NBPL Credit Agreement set forth under this Item 1.01 is
qualified in its entirety by reference to the complete terms and conditions of
the NBPL Credit Agreement itself, which is filed as Exhibit 10.2 hereto.

ITEM 1.02         TERMINATION OF A MATERIAL DEFINITIVE AGREEMENT

As disclosed under Item 1.01 of this current report, which disclosure is
incorporated into this Item 1.02 in its entirety, effective May 16, 2005 we
terminated our $275 million Revolving Credit Agreement dated as of November 24,
2003 among us, SunTrust Bank, Harris Nesbitt Corp., Wachovia Bank, National
Association, Citigroup, N.A., SunTrust Capital Markets, Inc. and lenders named
therein.

ITEM 2.03         CREATION OF A DIRECT FINANCIAL OBLIGATION

The information disclosed under Item 1.01 of the current report is incorporated
into this Item 2.03 in its entirety.

ITEM 9.01  FINANCIAL STATEMENTS AND EXHIBITS
