                              PART I

Item 1.   Business

General

     Northern Border Partners, L.P. through a subsidiary
limited partnership, Northern Border Intermediate Limited
Partnership, collectively referred to herein as
"Partnership", owns a 70% general partner interest in
Northern Border Pipeline Company, a Texas general
partnership ("Northern Border Pipeline").  The remaining
general partner interests in Northern Border Pipeline are
owned by TransCanada Border PipeLine Ltd. (6%) and TransCan
Northern Ltd. (24%), both of which are wholly-owned
subsidiaries of TransCanada PipeLines Limited
("TransCanada").

     Northern Plains Natural Gas Company ("Northern
Plains"), Pan Border Gas Company ("Pan Border") and
Northwest Border Pipeline Company ("Northwest Border") serve
as the General Partners of the Partnership.  Northern Plains
is a wholly-owned subsidiary of Enron Corp. ("Enron"), and
Northwest Border is a wholly-owned subsidiary of The
Williams Companies, Inc. ("Williams").  In December 1998,
Northern Plains acquired Pan Border from a subsidiary of
Duke Energy Corporation.  At the closing, Pan Border's sole
asset consisted of its general partner interest in the
Partnership.  The General Partners hold an aggregate 2%
general partner interest in the Partnership.  The General
Partners or their affiliates also own Common Units
representing an aggregate 14.5% limited partner interest.
The combined general and limited partner interests in the
Partnership of Enron and Williams are 12.4% and 4.1%,
respectively (See "Certain Relationships and Related
Transactions").  The Partnership is managed by or under the
direction of the Partnership Policy Committee consisting of
three members, each of whom has been appointed by one of
the General Partners (See "Partnership Management").

    The Partnership's 70% interest in Northern Border Pipeline
represents substantially all its assets.  Northern Border Pipeline 
owns a 1,214-mile U.S. interstate pipeline system (the "Pipeline System")
that transports natural gas from the Montana-Saskatchewan border
near Port of Morgan, Montana, to interconnecting pipelines
and local distribution systems in the States of North
Dakota, South Dakota, Minnesota, Iowa and Illinois, providing
shippers access to markets in the Midwest, including
Chicago.  The Pipeline System has pipeline access to natural
gas reserves in the Western Canadian Sedimentary Basin
located in the Canadian provinces of Alberta, British
Columbia and Saskatchewan, as well as the Williston Basin in
the United States.  The Pipeline System also has access to
production of synthetic gas from the Dakota Gasification
Plant in North Dakota.  Northern Border Pipeline shippers
can arrange transportation, displacement and exchange
agreements with third parties to provide access beyond
Chicago to markets throughout the United States.

     Management of Northern Border Pipeline is overseen by
the Northern Border Management Committee, which is comprised
of three representatives from the Partnership (one
designated by each General Partner) and one representative
from the TransCanada subsidiaries.  The Pipeline System is
operated by Northern Plains pursuant to an operating
agreement.  Northern Plains employs approximately 190
individuals located at the operating headquarters in Omaha,
Nebraska, and at various locations along the pipeline route.
Northern Plains' employees are not represented by any labor
union and are not covered by any collective bargaining
agreements.

     Northern Border Pipeline transports gas for shippers
under a tariff regulated by the Federal Energy Regulatory
Commission ("FERC").  The tariff specifies the calculation
of amounts to be paid by shippers and the general terms and
conditions of transportation service on the Pipeline System.
Northern Border Pipeline's revenues are derived from
agreements for the receipt and delivery of gas at points
along the Pipeline System as specified in each shipper's
individual transportation contract. Northern Border Pipeline
does not own the gas that it transports, and therefore it
does not assume the risk of loss from decreases in market
prices for gas transported on the Pipeline System.

     The Partnership also owns Black Mesa Pipeline Holdings,
Inc. ("Black Mesa"). Black Mesa, through a wholly-owned
subsidiary, owns a 273-mile, 18-inch diameter coal slurry
pipeline which originates at a coal mine in Kayenta,
Arizona.  The coal slurry pipeline transports crushed coal
suspended in water.  It traverses westward through northern
Arizona to the 1,500 megawatt Mohave Power Station located
in Laughlin, Nevada.  The coal slurry pipeline is the sole
source of fuel for the Mohave Power Station, which consumes
an average of 4.8 million tons of coal annually.  The
capacity of the pipeline is fully contracted to the coal
supplier for the Mohave Power Station through the year 2005.
The pipeline is operated by Black Mesa Pipeline Operations,
LLC, a wholly-owned subsidiary of the Partnership.
Approximately 59 people are employed in the operations of
Black Mesa, of which 26 are represented by a labor union,
the United Mine Workers.  The cash flow from the coal slurry
pipeline represents only about 2% of the Partnership's total
cash flow.

The Pipeline System

     The Pipeline System consists of 822-miles of 42-inch
diameter pipe designed to transport 2,373 million cubic feet
of natural gas per day ("MMcfd") from the Canadian border to
Ventura, Iowa; 30-inch diameter pipe and 36-inch diameter
pipe, each approximately 147 miles in length, designed to
transport 1,300 MMcfd from Ventura, Iowa to Harper, Iowa;
and 226 miles of 36-inch diameter pipe and 19 miles of 30-
inch diameter pipe designed to transport 645 MMcfd from
Harper, Iowa to a terminus near Manhattan, Illinois (Chicago
area).  Along the pipeline, there are fifteen compressor
stations with total rated horsepower of 476,500 and
measurement facilities to support the receipt and delivery
of gas at various points along the pipeline.  Other
facilities include five field offices and a microwave
communication system with 51 tower sites.

     Interconnecting pipeline facilities provide Northern
Border Pipeline shippers with flexible access to natural gas
markets.  The Pipeline System interconnects with the
pipeline facilities of:
     
     *  Northern Natural Gas Company ("Northern Natural"), an
        Enron subsidiary, at Ventura, Iowa as well as multiple
        smaller interconnections in South Dakota, Minnesota and
        Iowa;
     *  Natural Gas Pipeline Company of America at Harper,
        Iowa;
     *  MidAmerican Energy Company at Iowa City and Davenport,
        Iowa;
     *  Interstate Power Company at Prophetstown, Illinois;
     *  Northern Illinois Gas Company at Troy Grove and
        Minooka, Illinois;
     *  Midwestern Gas Transmission Company near Channahon,
        Illinois;
     *  ANR Pipeline Company near Manhattan, Illinois; and
     *  The Peoples Gas Light and Coke Company near Manhattan,
        Illinois (Chicago area) at the terminus of the Pipeline
        System.

     At its northern end, the Pipeline System's largest
receipt point  is its connection to the Foothills Pipe Lines
(Sask.) Ltd. system in Canada, which in turn is connected to
the pipeline systems of NOVA Gas Transmission Ltd. ("NOVA")
in Alberta and of Transgas Limited in Saskatchewan.  The
NOVA system gathers and transports a substantial portion of
Canadian natural gas production.  The Pipeline System also
connects with the facilities of Williston Basin Interstate
Pipeline at Glen Ullin and Buford, North Dakota, facilities
of Amerada Hess Corporation at Watford City, North Dakota
and facilities of Dakota Gasification Company at Hebron,
North Dakota in the northern portion of the system.

     The Pipeline System was initially constructed in 1982
with capacity additions in 1991, 1992 and 1998.  A recent
expansion, called The Chicago Project, was placed into
service in December 1998 and increased the Pipeline System's
capacity by 42% to its current capacity of 2,373 MMcfd.  The
estimated cost of The Chicago Project is $892 million (See
"FERC Regulation - Cost of Service Tariff").

Future Demand and Competition

     Northern Border Pipeline's operations are supported by
significant supplies of natural gas in Canada.  In 1998,
approximately 88% of the natural gas transported by the
Pipeline System was produced in the Western Canadian
Sedimentary Basin.  Northern Border Pipeline's capacity
utilization was an average of 99% of summer design capacity
during 1998.  It is estimated that the Pipeline System's
share of Canadian gas exported to the United States in
January and February 1999, the first full two months of
operations of The Chicago Project, was nearly 23%.

     On November 17, 1997, Northern Border Pipeline
announced the commencement of an open season during which
prospective shippers were invited to submit requests for
capacity on a possible further expansion and extension of
the Pipeline System ("Project 2000").  From the bids
submitted, project shippers signed precedent agreements for
additional capacity from Port of Morgan, Montana to Ventura,
Iowa of 62 MMcfd and from Ventura, Iowa to Manhattan, Illinois
of 185 MMcfd and new capacity to North Hayden, Indiana of
545 MMcfd.  In October 1998, Northern Border Pipeline filed
a certificate application with the FERC to construct and
operate facilities necessary to transport these volumes with
construction costs estimated to be approximately $190 million.
If approved and constructed, Project 2000 will strategically
position Northern Border Pipeline to move gas east and will
place it in direct contact with major industrial gas comsumers.
Project 2000 would afford shippers access to the northern
Indiana industrial zone, including Northern Indiana Public
Service Company, a major Midwest local distribution company
with a large industrial load requirement and total annual
system deliveries in excess of 300 billion cubic feet.
A notice to prepare an environmental assessment for this
project was issued by the FERC on January 22, 1999 to all affected
landowners and other interested parties giving those parties
the opportunity to provide comments.  Northern Border
Pipeline has been advised that permanent releases of
existing capacity have been negotiated between several existing
and project shippers.  If such releases are finalized,
certain proposed facilities will not be needed, reducing the
estimated construction cost to approximately $130 million, and
an amendment of the certificate application will be filed
advising FERC of these changes.

     Northern Border Pipeline competes with other pipeline
companies that transport gas from the Western Canadian
Sedimentary Basin or that transport gas to end-use markets
in the Midwest.  Its competitive position is affected by the
availability of Canadian natural gas for export and demand
for natural gas in the United States.  Shippers of gas
produced in the Western Canadian Sedimentary Basin have
other options to transport Canadian natural gas to the
United States, including transportation on pipelines
eastward in Canada or to markets on the West Coast.

     The sponsors of the Alliance Pipeline project recently
received Canadian and United States regulatory approvals for
the construction of a new pipeline to originate in western
Canada and terminate in the vicinity of Chicago, Illinois.
These sponsors have announced their plans for the pipeline
to be in service by October 2000.  The new pipeline would
directly compete with Northern Border Pipeline by
transporting gas from the Western Canadian Sedimentary Basin
to the midwestern United States.  Although there may be a
large increase in natural gas moving from the Western
Canadian Sedimentary Basin into the Chicago market, there are
several additional projects proposed to transport natural gas
from the Chicago area to growing eastern markets.  The proposed
projects, currently being pursued by unrelated third
parties, are targeting markets in eastern Canada and the
northeast United States.  None of these proposed projects
has received final regulatory approval.

Shippers

     The Pipeline System serves a number of shippers with
diverse financial and business profiles.  Based on shippers'
cost of service obligations, 93% of the capacity is
contracted by producers and marketers.  The remaining
capacity is contracted primarily by interstate pipelines
(2%) and local distribution companies (5%).  At present, the
termination dates of these contracts range from October 31,
2001 to December 21, 2013.  The weighted average contract
life as of December 31, 1998 (based upon shippers' cost of
service obligations) is slightly under eight years with 97%
of capacity contracted through mid-September 2003.

     Firm shippers on the Pipeline System as of December 31,
1998 that are affiliated with general partners of the
Partnership or the general partners of Northern Border
Pipeline are: Enron Capital & Trade Resources Corp.("ECT"),
a subsidiary of Enron; TransCanada Gas Services Inc., a
subsidiary of, and as agent for, TransCanada; and
Transcontinental Gas Pipe Line Corporation ("Transco"), a
subsidiary of Williams.  Together those shippers currently
hold 16.9% of capacity.

     Northern Border Pipeline's largest shipper, Pan-Alberta
Gas U.S. Inc. ("PAGUS"), currently holds 707 MMcfd, 26.5% of
the capacity, under three transportation contracts with terms
that have been extended to October 31, 2003.  The extension of
the termination date for one of the contracts covering 150
MMcfd is subject to further FERC authorization.  An
affiliate of Enron provides guaranties for 300 MMcfd, of
PAGUS' contractual obligations through October 31, 2001.  In
addition, PAGUS' remaining transportation capacity is
supported by various credit support arrangements including,
among others, a letter of credit, a guaranty from an
interstate pipeline company through October 31, 2001 for 150
MMcfd, an escrow account and an upstream capacity transfer
agreement.

FERC Regulation

General

     FERC extensively regulates Northern Border Pipeline as
a "natural gas company" under the Natural Gas Act (the
"NGA").  Under the NGA and the Natural Gas Policy Act,
the FERC has jurisdiction over Northern Border
Pipeline with respect to virtually all aspects of its
business, including transportation of gas, rates and
charges, construction of new facilities, extension or
abandonment of service and facilities, accounts and records,
depreciation and amortization policies, the acquisition and
disposition of facilities, the initiation and
discontinuation of services, and certain other matters.
Northern Border Pipeline, where required, holds certificates
of public convenience and necessity issued by the FERC
covering its facilities, activities and services.  Under
Section 8 of the NGA, the FERC has the power to prescribe
the accounting treatment for items for regulatory purposes.
The Northern Border Pipeline books and records are
periodically audited pursuant to Section 8.

     Northern Border Pipeline's rates and charges for
transportation in interstate commerce are subject to
regulation by the FERC.  Natural gas companies may not
charge rates exceeding rates deemed just and reasonable by
the FERC.  In addition, the FERC prohibits natural gas
companies from unduly preferring or unreasonably
discriminating against any person with respect to pipeline
rates or terms and conditions of service.  Certain types of
rates may be discounted without further FERC authorization.

Cost of Service Tariff

     Northern Border Pipeline's firm transportation shippers
contract to pay for an allocable share of the cost of
service associated with the Pipeline System's capacity.
During any given month, all such shippers pay a uniform
mileage-based charge for the amount of capacity contracted,
calculated under a cost of service tariff.  The shippers are
obligated to pay their allocable share of the cost of
service regardless of the amount of gas they actually
transport.  The cost of service tariff is regulated by the
FERC and provides an opportunity to recover all operations
and maintenance costs of the Pipeline System, taxes other
than income taxes, interest, depreciation and amortization,
an allowance for income taxes and a regulated equity return.
Northern Border Pipeline may not charge or collect more than
its cost of service pursuant to its tariff on file with the
FERC.

     Northern Border Pipeline's investment in the Pipeline
System is reflected in various accounts referred to
collectively as its regulated "rate base."  The cost of
service includes a return, with related income taxes, on the
rate base.  Over time, the rate base declines as a result of,
among other things, the monthly depreciation and
amortization.  The Northern Border Pipeline rate base
includes, as an additional amount, a one-time ratemaking
adjustment to reflect the receipt of a financial
incentive on the original construction of the pipeline.
Since inception, the rate base adjustment, called an incentive
rate of return ("IROR"), has been amortized through monthly
additions to the cost of service.  As a result, the Partnership's
net income for 1998 included $9.9 million for such amortization
along with a related income tax allowance, net of the effect of
minority interests.  This impact on net income is expected
to continue until November 2001 when the IROR is fully
amortized.

     Northern Border Pipeline bills the cost of service on
an estimated basis for a six month cycle.  Any net excess or
deficiency resulting from the comparison of the actual cost
of service, determined in accordance with the FERC tariff,
to the estimated billing is accumulated, including carrying
charges thereon, and is either billed to or credited back to
the shippers' accounts.

     Northern Border Pipeline also provides interruptible
transportation service.  The maximum rate charged to
interruptible shippers is calculated from cost of service
estimates on the basis of contracted capacity.  Except for
certain limited situations, all revenue from the
interruptible transportation service is credited back to the
firm shippers' accounts.

     In its 1995 rate case, Northern Border Pipeline reached
a settlement that was filed in a Stipulation and Agreement
("Stipulation").  Although it was contested, it was approved
by the FERC on August 1, 1997.  In the Stipulation, the
depreciation rate was established at 2.5% from January 1,
1997 through the in-service date of The Chicago Project and
at that time, it was reduced to 2.0%.  Starting in the year
2000, the depreciation rate is scheduled to increase
gradually on an annual basis until it reaches 3.2% in 2002.

     The Stipulation also determined several other cost of
service parameters.  In accordance with the effective
tariff, Northern Border Pipeline's allowed equity rate of
return is 12%.  For at least seven years from the date The
Chicago Project was completed, Northern Border Pipeline,
under the terms of the Stipulation,  may continue to
calculate its allowance for income taxes as a part of its
cost of service in the manner it has historically used.  In
addition, a settlement adjustment mechanism of $31 million
was implemented, which effectively reduces the allowed
return on rate base.

     Also as agreed to in the Stipulation, Northern Border
Pipeline implemented a capital project cost containment
mechanism ("PCCM"). The purpose of the PCCM was to limit
Northern Border Pipeline's ability to include cost overruns
on The Chicago Project in rate base and to provide
incentives to Northern Border Pipeline for cost underruns.
The PCCM amount is determined by comparing the final cost of
The Chicago Project to the budgeted cost.  If there is a
cost overrun of $6 million or less, the shippers will bear
the actual cost of the project through its inclusion in
Northern Border Pipeline's rate base.  If there is a cost
savings of $6 million or less, the full budgeted cost will
be included in the rate base.  If there is a cost overrun or
cost savings of more than $6 million but less than 5% of the
budgeted cost, that amount will be allocated 50% to Northern
Border Pipeline and 50% to its shippers (50% of the
difference between 5% of the budgeted cost and $6 million
will be included in Northern Border Pipeline's rate base,
and 50% will be excluded).  All cost overruns exceeding 5%
of the budgeted cost are excluded from the rate base.
     
     The Stipulation required the budgeted cost for The
Chicago Project, which had been initially filed with the
FERC for approximately $839 million, to be adjusted for the
effects of inflation and project scope changes, as defined
in the Stipulation.  Such adjusted budgeted cost has been
estimated as of the December 22, 1998 in-service date to be
$889 million, with the final construction cost estimated to be
$892 million.  Thus, Northern Border Pipeline's report to the FERC
and its shippers in late December 1998, reflected the
conclusion that, based on information as of that date, once
the budgeted cost has been established, there would be no
adjustment to rate base as a result of the PCCM.  Northern
Border Pipeline is obligated by the Stipulation to update
its calculation of the PCCM six months after the in-service
date of The Chicago Project.  The Stipulation requires the
calculation of the PCCM to be reviewed by an independent
national accounting firm.  Several parties to the
Stipulation have advised the FERC that they may have
questions and desire further information about the report,
and may possibly wish to test it (or the final report) and
the conclusions contained therein in an appropriate
proceeding in the future.  The parties also stated that if
it is determined that Northern Border Pipeline is not able
to include certain claimed costs for The Chicago Project in
its rate base, they reserve their rights to seek refunds,
with interest, of any overcollections.  Although the
Partnership believes the initial computation has been made
pursuant to the terms of the Stipulation, it is unable to
make a definitive determination at this time whether any
adjustments will be required.  Should subsequent
developments cause costs not to be recovered pursuant to the
PCCM, a non-cash charge to write down transmission plant may
result, and such charge could be material to the operating
results of the Partnership.

   Northern Border Pipeline is required by the terms of its
tariff to file a rate case with the FERC by no later than
May 31, 1999 for a redetermination of its allowed equity
rate of return.  The Partnership cannot predict the impact,
if any, of the outcome of the next rate case.

Proposed Regulations

     In a Notice of Proposed Rulemaking ("NOPR") issued on
July 29, 1998, the FERC proposed changes to its regulations
governing short-term transportation services.  Among the
proposals considered in the NOPR are:

     *    Auctions for short-term capacity;
     *    Removal of price caps for secondary market
          transactions;
     *    Revisions to FERC's reporting requirements;
     *    Revisions to tariff provisions governing imbalances;
          and
     *    Negotiated services.

     In a companion Notice of Inquiry issued the same day,
the FERC requested industry comment on its pricing policies
in the existing long-term market for transportation services
and its pricing policies for new capacity.  The FERC also
issued a NOPR to revise its procedures under which shippers
or others may have complaints considered by the FERC.  The
Partnership cannot assess the impact on Northern Border
Pipeline of any final rules adopted by the FERC as a result
of these proceedings at this time.

     The FERC also commenced proceedings to revise its
pipeline construction regulations.  On September 30, 1998,
the FERC issued a NOPR to amend its regulations to reflect
current FERC policies governing the issuance of pipeline
construction certificates and to codify the filing of
certain related information.  Also on September 30, 1998,
the FERC issued a NOPR that would give applicants seeking to
construct, operate or abandon natural gas services or
facilities the option of using a pre-filing collaborative
process to resolve significant issues among parties and the
pipeline.  The NOPR also proposes that a significant portion
of the environmental review process could be completed as
part of the collaborative process.  As part of the NOPR, the
FERC intends to examine existing landowner and pipeline
construction issues.  The Partnership cannot assess the
impact on Northern Border Pipeline of any final rules
adopted by the FERC as a result of these proceedings at this
time.

Environmental and Safety Matters

     The operations of the Partnership are subject to
federal, state and local laws and regulations relating to
safety and the protection of the environment which include
the Resource Conservation and Recovery Act, the
Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, Clean Air Act, as
amended, the Clean Water Act, as amended, the Natural Gas
Pipeline Safety Act of 1969, as amended, and the Pipeline
Safety Act of 1992.  Although the Partnership believes that
its operations and facilities are in general compliance in
all material respects with applicable environmental and
safety regulations, risks of substantial costs and
liabilities are inherent in pipeline operations, and the
Partnership cannot provide any assurances that it will not
incur such costs and liabilities.  Moreover, it is possible
that other developments, such as increasingly strict
environmental and safety laws, regulations and enforcement
policies thereunder, and claims for damages to property or
persons resulting from the Partnership's operations, could
result in substantial costs and liabilities to the Partnership.
If the Partnership is unable to recover such resulting costs,
cash distributions could be adversely affected.


Item 2.   Properties

     Northern Border Pipeline holds the right, title and
interest in the Pipeline System.  With respect to real
property, the Pipeline System falls into two basic
categories: (a) parcels which Northern Border Pipeline owns
in fee, such as certain of the compressor stations,
measurement stations, pipeline field office sites, and
microwave tower sites; and (b) parcels where the interest of
Northern Border Pipeline derives from leases, easements,
rights-of-way, permits or licenses from landowners or
governmental authorities permitting the use of such land for
the construction and operation of the Pipeline System.  The
right to construct and operate the pipeline across certain
property was obtained by Northern Border Pipeline through
exercise of the power of eminent domain.  Northern Border
Pipeline continues to have the power of eminent domain in
each of the states in which it operates the Pipeline System,
although it may not have the power of eminent domain with
respect to Native American tribal lands.

     Approximately 90 miles of the pipeline is located on
fee, allotted and tribal lands within the exterior
boundaries of the Fort Peck Indian Reservation in Montana.
Tribal lands are lands owned in trust by the United States
for the Fort Peck Tribes and allotted lands are lands owned
in trust by the United States for an individual Indian or
Indians.  In 1980, Northern Border Pipeline entered into a
pipeline right-of-way lease with the Fort Peck Tribal
Executive Board, for and on behalf of the Assiniboine and
Sioux Tribes of the Fort Peck Indian Reservation.  This
pipeline right-of-way lease, which was approved by the
Department of the Interior in 1981, granted to Northern
Border Pipeline the right and privilege to construct and
operate its pipeline on certain tribal lands, for a term of
15 years, renewable for an additional 15 year term at the
option of Northern Border Pipeline without additional
rental.  Northern Border Pipeline notified the Bureau of
Indian Affairs ("BIA") in March 1996 that it was exercising
its option to renew the pipeline right-of-way lease for an
additional 15 year term.  Northern Border Pipeline continues
to operate on this portion of the pipeline located on tribal
lands in accordance with its renewal rights.

     In conjunction with obtaining a pipeline right-of-way
lease across tribal lands located within the exterior
boundaries of the Fort Peck Indian Reservation, Northern
Border Pipeline also obtained a right-of-way across allotted
lands located within the reservation boundaries.  This right-
of-way, granted by the BIA on March 25, 1981, for and on
behalf of individual Indian owners, expired on March 31,
1996.  Before the termination date, Northern Border Pipeline
undertook efforts to obtain voluntary consents from
individual Indian owners for a new right-of-way, and
Northern Border Pipeline filed applications with the BIA for
new right-of-way grants across those tracts of allotted
lands where a sufficient number of consents from the Indian
owners had been obtained.  Also, a condemnation action was
filed in Federal Court in the District of Montana concerning
those remaining tracts of allotted land for which a majority
of consents were not timely received.  An order in this
proceeding was issued by the Federal Court granting Northern
Border Pipeline continued access and possession during the
pendency of the condemnation action on the tracts in
question.  A stipulation has been entered into involving all
but one tract involved in the condemnation action in which
the parties have agreed that the Court may enter an order
assessing compensation in the amount established in an
agreed upon appraisal.  A hearing was held by the Court in
January 1999 in which evidence was presented on the value of
the interest being condemned.  No order has been entered as
yet.  Amounts ordered by the Court as compensation should be
included in Northern Border Pipeline's cost of service.  To
date the BIA has not issued a formal right-of-way grant for
those tracts for which sufficient landowners consents were
obtained.  It is anticipated that the issuance of such a
grant will take place in conjunction with the resolution of
the condemnation action.


Item 3.   Litigation

     The Partnership and its subsidiaries are not currently
parties to any legal proceedings that, individually or in
the aggregate, would reasonably be expected to have a
material adverse impact on the Partnership's results of
operations or financial position.


Item 4.   Submission of Matters to a Vote of Security Holders

     As of March 5, 1999, there were approximately 1,656
record holders of Common Units and approximately 34,538
beneficial owners of the Common Units, including Common
Units held in street name.

     The Partnership currently has 29,347,313 Common Units
outstanding, representing a 98% limited partner interest.
The Common Units are the only outstanding limited partner
interests.  Thus, the Partnership's equity consists of
general partner interests representing in the aggregate a 2%
interest and Common Units representing in the aggregate a
98% limited partner interest.
     
     In general, the General Partners are entitled to 2% of
all cash distributions, and the holders of Common Units are
entitled to the remaining 98% of all cash distributions,
except that the General Partners are entitled to incentive
distributions if the amount distributed with respect to any
quarter exceeds $0.605 per Common Unit ($2.42 annualized).
Under the incentive distribution provisions, the General
Partners are entitled to 15% of amounts distributed in
excess of $0.605 per Common Unit, 25% of amounts distributed
in excess of $0.715 per Common Unit ($2.86 annualized) and
50% of amounts distributed in excess of $0.935 per Common
Unit ($3.74 annualized).  The amounts that trigger incentive
distributions at various levels are subject to adjustment in
certain events, as described in the Partnership Agreement.
On January 19, 1999, the Partnership declared an increase in
the distribution to $0.61 per Unit ($2.44 per Unit on an
annualized basis), payable February 12, 1999 to the General
Partners and Unitholders of record at January 29, 1999.

     On May 31, 1997, the Partnership issued 125,357 Common
Units in a private placement, exempt pursuant to Section
4(2) of the Securities Act of 1933, to the stockholders of
Williams Technologies, Inc., an Oklahoma corporation
("WTI"), in consideration of the sale by such stockholders
to the Partnership of all of the capital stock of WTI.

     On December 29, 1997, the Partnership issued 46,956
Common Units in a private placement, exempt pursuant to
Section 4(2) of the Securities Act of 1933, to Central
Pacific Resources Partnership as partial consideration for
the acquisition by the Partnership of an interest in Black
Mesa Pipeline Operations, LLC.

     On January 19, 1999, the 6,420,000 Subordinated Units
outstanding were converted into 6,420,000 Common Units in
accordance with their terms in a transaction that was exempt
from registration pursuant to Section 3(a)(9) of the
Securities Act of 1933.

Item 7.  Management's Discussion and Analysis of
         Financial Condition and Results of Operations

Results of Operations

Year Ended December 31, 1998 Compared With the Year Ended December 31, 1997

   Operating revenue increased $19.0 million for the year ended
December 31, 1998, as compared to the results for the comparable
period in 1997.  Operating revenue attributable to Northern
Border Pipeline increased $10.5 million due primarily to returns
on higher levels of invested equity.  Northern Border Pipeline's
FERC tariff provides an opportunity to recover all of the
operations and maintenance costs of the pipeline, taxes other
than income taxes, interest, depreciation and amortization, an
allowance for income taxes and a regulated return on equity.
Northern Border Pipeline is generally allowed to collect from its
shippers a return on unrecovered rate base as well as recover
that rate base through depreciation and amortization.  The return
amount Northern Border Pipeline collects from its shippers
declines as the rate base is recovered.  As a result of placing
the facilities for The Chicago Project into service, Northern
Border Pipeline added approximately $840 million to its gas plant
in service in 1998 (See "Business-The Pipeline System").
Operating revenue for Black Mesa was $21.0 million in 1998 as
compared to $12.5 million in 1997, which represented seven months
of revenue. On May 31, 1997, the Partnership increased its
ownership interest of Black Mesa and began to reflect its
operating results on a consolidated basis.  Prior to that time,
Black Mesa was accounted for on the equity method and included in
other income.

   Operations and maintenance expense increased $7.4 million for
the year ended December 31, 1998, from the comparable period in
1997.  Operations and maintenance expense for Black Mesa was
$13.8 million in 1998 as compared to $7.7 million in 1997, which
represented seven months of expense.

   Depreciation and amortization expense increased $3.4 million
for the year ended December 31, 1998, as compared to the same
period in 1997.  Depreciation and amortization expense
attributable to Northern Border Pipeline increased $2.3 million
primarily due to facilities that were placed in service in 1998.
Depreciation and amortization expense for Black Mesa was $2.6
million in 1998 as compared to $1.5 million in 1997, which
represented seven months of expense.

   For the year ended December 31, 1998, Northern Border Pipeline
recorded a regulatory credit of approximately $8.9 million.
During the construction of The Chicago Project, Northern Border
Pipeline placed certain new facilities into service in advance of
the December 1998 in service date to maintain gas flow at firm
contracted capacity while existing facilities were being
modified.  The regulatory credit results in deferral of the cost
of service of these new facilities.  Northern Border Pipeline is
allowed to recover from its shippers the regulatory asset that
resulted from the cost of service deferral over a ten-year period
commencing with the in service date of The Chicago Project.

   Interest expense, net increased slightly for the year ended
December 31, 1998, as compared to the results for the same period
in 1997, due to an increase in interest expense of $15.4 million
offset by an increase in the amount of interest expense
capitalized of $15.3 million.  Interest expense attributable to
Northern Border Pipeline and the Partnership increased $14.6
million due primarily to an increase in average debt outstanding,
reflecting amounts borrowed to finance a portion of the capital
expenditures for The Chicago Project.  The remainder of the
increase in interest expense is from Black Mesa, which was $2.3
million for 1998 as compared to $1.5 million for seven months in
1997.  The increase in interest expense capitalized primarily
relates to Northern Border Pipeline's expenditures for The
Chicago Project.

   Other income increased $4.9 million for the year ended
December 31, 1998, as compared to the same period in 1997.  The
increase was primarily due to an $8.8 million increase in the
allowance for equity funds used during construction.  The
increase in the allowance for equity funds used during
construction primarily relates to Northern Border Pipeline's
expenditures for The Chicago Project.  Other income for 1997
included $4.8 million received by Northern Border Pipeline for
vacating certain microwave frequency bands.

   Minority interests in net income increased $7.8 million for
the year ended December 31, 1998, as compared to the same period
in 1997, due to increased net income for Northern Border
Pipeline.

Year Ended December 31, 1997 Compared With the Year Ended
December 31, 1996

   Operating revenue decreased $3.4 million for the year ended
December 31, 1997, as compared to the results for the comparable
period in 1996.  Operating revenue attributable to Northern
Border Pipeline decreased $15.9 million due primarily to lower
depreciation and amortization expense, taxes other than income
and returns on a lower rate base.  Additionally, in accordance
with the Stipulation approved by the FERC to settle Northern
Border Pipeline's November 1995 rate case, the allowed equity
rate of return was 12.75% through September 30, 1996 and 12.0%
thereafter (See "Business-FERC Regulation-Cost of Service
Tariff").  These lower recoveries were partially offset by higher
operations and maintenance expense recoveries.  Operating revenue
for Black Mesa was $12.5 million for 1997.

   Operations and maintenance expense increased $9.1 million for
the year ended December 31, 1997, from the comparable period in
1996 due primarily to $7.7 million of expense for Black Mesa.
Operations and maintenance expense attributable to Northern
Border Pipeline increased $1.5 million for the year ended
December 31, 1997, from the comparable period in 1996 due
primarily to higher administrative expenses.

   Depreciation and amortization expense decreased $6.8 million
for the year ended December 31, 1997, as compared to the same
period in 1996.  Depreciation and amortization expense
attributable to Northern Border Pipeline decreased $8.3 million.
In accordance with the terms of the Stipulation, the depreciation
rate applied to Northern Border Pipeline's gross transmission
plant was 2.5% for 1997.  The average depreciation rate applied
to gross transmission plant for the year ended December 31, 1996
was 3.1%.  Depreciation and amortization expense for Black Mesa
was $1.5 million for 1997.

   Taxes other than income decreased $1.6 million for the year
ended December 31, 1997, as compared to the results for the same
period in 1996.  Taxes other than income attributable to Northern
Border Pipeline decreased $2.0 million due primarily to lower
property tax assessments received in various states where the
pipeline system operates.  Taxes other than income for Black Mesa
was $0.4 million for 1997.

   Interest expense, net decreased $1.8 million for the year
ended December 31, 1997, as compared to the results for the same
period in 1996, due to an increase in interest expense of $1.4
million offset by an increase in the amount of interest expense
capitalized of $3.2 million.  The increase in interest expense
was due primarily to Black Mesa.  The increase in interest
expense capitalized primarily relates to Northern Border
Pipeline's expenditures for The Chicago Project.

   Other income increased $5.1 million for the year ended
December 31, 1997, as compared to the same period in 1996.  The
increase was primarily due to $4.8 million received by Northern
Border Pipeline for vacating certain microwave frequency bands
and a $1.0 million increase in the allowance for equity funds
used during construction.  The increase in the allowance for
equity funds used during construction primarily relates to
Northern Border Pipeline's expenditures for The Chicago Project.

Liquidity and Capital Resources

General

   In June 1997, Northern Border Pipeline entered into a credit
agreement ("Pipeline Credit Agreement") with certain financial
institutions to borrow up to an aggregate principal amount of
$750 million.  The Pipeline Credit Agreement is comprised of a
$200 million five-year revolving credit facility to be used for
the retirement of Northern Border Pipeline's bank loan agreements
and for general business purposes, and a $550 million three-year
revolving credit facility to be used for the construction of The
Chicago Project.  The three-year revolving credit facility may,
if certain conditions are met, be converted to a term loan
maturing in June 2002.  Northern Border Pipeline intends to, and
has the ability to, convert the three-year revolving credit
facility to a term loan in 1999.  At December 31, 1998, $127.5
million and $484.5 million had been borrowed on the five-year and
three-year revolving credit facilities, respectively.

   In November 1997, the Partnership entered into a credit
agreement ("Partnership Credit Agreement") with certain financial
institutions to borrow up to an aggregate principal amount of
$175 million under a revolving credit facility.  The Partnership
Credit Agreement is to be used for interim funding of the
Partnership's required capital contributions to Northern Border
Pipeline for construction of The Chicago Project.  The amount
available under the Partnership Credit Agreement is reduced to
the extent the Partnership issues additional limited partner
interests to fund the Partnership's capital contributions for The
Chicago Project in excess of $25 million.  The public offerings
of Common Units discussed in the following paragraph reduced the
amount available under the Partnership Credit Agreement to $104
million.  The maturity date of the Partnership Credit Agreement
will be November 2000 if Northern Border Pipeline converts its
$550 million three-year revolving credit facility to a term loan;
otherwise the maturity date is June 2000.  At December 31, 1998,
$95 million had been borrowed on the Partnership Credit
Agreement.

   In December 1997, the Partnership sold, through an
underwritten public offering, 2,750,000 Common Units.  In
conjunction with the issuance of the Common Units, the
Partnership's General Partners made capital contributions to the
Partnership to maintain a 2% general partner interest in
accordance with the partnership agreements.  The net proceeds of
approximately $90.9 million were used by the Partnership to fund
a portion of the capital contributions to Northern Border
Pipeline for construction of The Chicago Project.  As part of the
underwritten public offering, the Partnership granted the
underwriters an over-allotment option to purchase a limited
number of additional Common Units.  This option was exercised on
January 5, 1998, and the Partnership sold an additional 225,000
Common Units resulting in additional net proceeds, including the
general partners' capital contributions, of approximately $7.6
million.

   In September 1998, Northern Border Pipeline executed interest
rate forward agreements with an aggregate notional amount of $150
million to hedge the interest rate for a planned issuance of
fixed rate debt during 1999.  Northern Border Pipeline plans to
use the proceeds from the debt borrowing to repay amounts
borrowed on the Pipeline Credit Agreement.

   In February 1999, the Partnership filed two registration
statements with the Securities and Exchange Commission ("SEC").
One registration statement was for a proposed offering of $200
million in Common Units and debt securities to be used by the
Partnership for general business purposes including repayment of
debt, future acquisitions, capital expenditures and working
capital.  The other registration statement was for a proposed
offering of 3,210,000 Common Units that are presently owned by
Northwest Border, a General Partner, and Panhandle Eastern Pipe
Line Company, of which the Partnership will not receive any
proceeds.

   Short-term liquidity needs will be met by internal sources and
through the lines of credit discussed above.  Long-term capital
needs may be met through the ability to issue long-term
indebtedness as well as additional limited partner interests of
the Partnership either through the registration statements
previously discussed or separate registrations.

Cash Flows From Operating Activities

   Cash flows provided by operating activities decreased $15.8
million to $103.8 million for the year ended December 31, 1998 as
compared to the same period in 1997 primarily related to a $36.3
million reduction for changes in other current assets and
liabilities partially offset by the effect of the refund activity
in 1997 discussed below.  For the year ended December 31, 1998,
the changes in other current assets and liabilities reflected a
decrease in accounts payable of $11.8 million as compared to an
increase of $14.6 million in 1997, exclusive of accruals for The
Chicago Project.  In addition, the changes in other current
assets and liabilities for 1998 reflected a decrease in over
recovered cost of service of $4.6 million and an increase in
under recovered cost of service of $2.8 million.  The over/under
recovered cost of service is the difference between Northern
Border Pipeline's estimated billings to its shippers, which are
determined on a six-month cycle, and the actual cost of service
determined in accordance with the FERC tariff.  The difference is
either billed to or credited back to the shippers accounts.  Cash
flows provided by operating activities decreased $17.9 million to
$119.6 million for the year ended December 31, 1997 as compared
to the same period in 1996 primarily related to a $52.6 million
refund in October 1997 in accordance with the Stipulation
approved by the FERC to settle Northern Border Pipeline's
November 1995 rate case.  During 1997, $40.4 million had been
collected subject to refund by Northern Border Pipeline as a
result of its rate case.

Cash Flows From Investing Activities

   Capital expenditures of $652.2 million for the year ended
December 31, 1998, include $638.7 million for The Chicago
Project (See "Business-The Pipeline System") and $11.7 million
for linepack gas.  The remaining $1.8 million of capital
expenditures for 1998 is primarily related to renewals and
replacements of existing facilities.  For the comparable period
in 1997, capital expenditures were $152.7 million, which
included $135.7 million for The Chicago Project and $17.0
million primarily related to renewals and replacements of
Northern Border Pipeline's existing facilities.

   Total capital expenditures for 1999 are estimated to be $131
million including $30 million for Project 2000 (see "Business-
Future Demand and Competition") and $85 million for The Chicago
Project.  Approximately $37 million of the capital expenditures
for The Chicago Project is for construction completed in 1998.
An additional $16 million of 1999 capital expenditures is
planned for renewals and replacements of the existing
facilities.  Northern Border Pipeline anticipates funding
its 1999 capital expenditures primarily by borrowing
on the Pipeline Credit Agreement and using working capital.
Funds required to meet the remainder of Northern Border
Pipeline's capital expenditures will be provided primarily
from capital contributions from the Partnership and minority
interest holders.  The Partnership intends to use a combination
of proceeds from the sale of Common Units, capital contributions
from its general partners and borrowings on the Partnership Credit
Agreement to finance its capital contributions to Northern Border
Pipeline.  The Partnership anticipates selling additional Common
Units to repay amounts borrowed on the Partnership Credit Agreement
to finance capital contributions for The Chicago Project.

   Cash flows provided by acquisition and consolidation of
businesses of $3.4 million for the year ended December 31, 1997,
are related primarily to the consolidation of Black Mesa's cash
balance.

Cash Flows From Financing Activities

   Cash flows provided by financing activities increased $387.0
million to $482.6 million for the year ended December 31, 1998,
as compared to the same period in 1997.  Financing activities for
1998 include borrowings under the Pipeline Credit Agreement and
Partnership Credit Agreement totaling $498.0 million and were
used primarily for construction expenditures related to The
Chicago Project.  In 1997, borrowings under the Pipeline Credit
Agreement totaled $209 million and were used primarily to retire
amounts related to Northern Border Pipeline's existing bank loan
agreements of $137.5 million and for construction expenditures
related to The Chicago Project.  Financing activities for 1998
reflect $7.6 million in net proceeds from the issuance of 225,000
Common Units and a related capital contribution by the
Partnership's general partners in January 1998.  In 1997,
financing activities reflect $90.9 million in net proceeds from
the issuance of 2,750,000 Common Units and a related capital
contribution by the Partnership's general partners in December
1997.  Contributions received from minority interests increased
$42.6 million to $66.9 million and were used by Northern Border
Pipeline to fund a portion of its capital expenditures.
Distributions to minority interests decreased $11.7 million to
$18.4 million primarily due to a change in the timing of Northern
Border Pipeline's distributions.

Year 2000

   The Partnership and its subsidiaries, similar to most
businesses, rely heavily on information systems technology to
operate in an efficient and effective manner.  Much of this
technology takes the form of computers and associated hardware
for data processing and analysis, but, in addition, a great deal
of information processing technology is embedded in
microelectronic devices.  The Year 2000 problem results from the
use in computer hardware and software of two digits rather than
four digits to define the applicable year.  As a result, computer
programs that have date-sensitive software may recognize a date
using "00" as the year 1900 rather than the year 2000.  If not
corrected, many computer applications could fail or create
erroneous results.  The effects of the Year 2000 problem are
compounded because of the interdependence of computer and
telecommunication systems in the United States and throughout the
world.  This interdependence is true for the Partnership, its
subsidiaries and their respective suppliers and customers.

   The Partnership and its subsidiaries have developed a plan,
which will be modified as events warrant, to address Year 2000
problems (the "Plan").  The Plan is designed to take reasonable
steps to prevent mission-critical functions from being impaired
due to the Year 2000 problem.  "Mission-critical" functions are
those critical functions whose loss would cause an immediate
stoppage of or significant impairment to major business areas  (a
major business area is one of material importance to the
Partnership's and its subsidiaries' businesses).  The Partnership
and its subsidiaries are committed to allocating the resources
necessary to implement the Plan.  A core team of individuals has
been established to implement and complete the Plan (the "Y2K
Team").  The Plan includes developing a comprehensive component
inventory of computer hardware, software, embedded chips and
third-party interfaces; assessing the risk of non-compliance of
each component; identifying the impact of any component failure;
assessing Year 2000 compliance of each component; identifying and
implementing solutions for non-compliance of components; testing
of solutions implemented; and developing contingency plans for
mission-critical components and systems.   As of February 1999,
computer software, hardware, embedded chips, and third-party
interfaces have been identified, inventoried, and assessed.
Where necessary, remediation, replacement, or adequate work-
arounds have been identified and implemented or are in the
process of being implemented.  Testing of computer hardware,
software, and embedded systems is ongoing and is expected to be
substantially completed early in the second quarter of 1999.

   The Plan recognizes that the computer, telecommunications and
other systems ("Outside Systems") of outside entities ("Outside
Entities") have the potential for major, mission-critical,
adverse effects on the conduct of the Partnership's and its
subsidiaries' businesses.  The Partnership and its subsidiaries
do not have control of these Outside Systems.  However, the Plan
includes an ongoing process of identifying and contacting Outside
Entities whose systems have or may have a substantial effect on
the Partnership's and its subsidiaries' ability to continue to
conduct the mission-critical aspects of their businesses without
disruption from Year 2000 problems.  The Plan requires the
Partnership and its subsidiaries to attempt to inventory and
assess the extent to which these Outside Systems may not be Year
2000 compatible.  The Y2K Team will attempt reasonably to
coordinate with these Outside Entities in an ongoing effort to
obtain assurances these Outside Systems will be Year 2000
compatible well before January 1, 2000.

   A listing of critical Outside Entities has been developed
which includes shippers, electrical suppliers, and
interconnecting pipelines.  Currently, the Y2K team is in the
process of contacting these entities to determine their Year 2000
readiness and the extent to which joint testing or mutual
contingency planning is required.  The assessment of the Year
2000 readiness of Outside Entities is an important factor in the
internal contingency planning process.

   The processes of inventorying, assessing, analyzing,
remediating through replacement or adequate work-arounds,
testing, and developing contingency plans for mission-critical
functions in anticipation of the year 2000 are necessarily
iterative processes.  That is, the steps are repeated as the Y2K
Team learns more about the Year 2000 problem and its effects on
internal systems and on Outside Systems, and about the effects
that embedded chips may have on the Partnership's and its
subsidiaries' systems and Outside Systems.  As the steps are
repeated, it is likely that new problems will be identified and
addressed.  The Partnership and its subsidiaries anticipate that
they will continue with these processes through January 1, 2000
and, if necessary based on experience, into the year 2000 in
order to assess and remediate problems that reasonably can be
identified only after the start of the new century.

   As part of the implementation of the Plan, the Y2K Team has
developed a contingency plan to minimize the consequences of
potential problems that have not been identified or that cannot
be remediated before January 1, 2000.  The contingency plan
concentrates on those areas that are essential to continuing
business operations and/or safety of its personnel and the
public.  These areas include, but are not limited to, systems
that are used to operate and control the Pipeline System and
enable the physical transportation of natural gas.  The
contingency plan includes the creation of teams that will be
standing by on December 31, 1999, prepared to respond rapidly and
otherwise as necessary to mission-critical Year 2000-related
problems as soon as they become known.  The composition of teams
that are assigned to deal with Year 2000 problems will vary
according to the mission-critical nature and location of the
problem.  The contingency plan is dynamic and will be continually
revised as potential new problem areas are identified and areas
are remediated.

   The Partnership and its subsidiaries have not incurred
material historical costs associated with the Year 2000 issues.
Further, the Partnership and its subsidiaries anticipate that
their future costs of implementing the Plan will not be material.
Although management believes its estimates are reasonable, there
can be no assurance, for the reasons stated in the following
paragraph, that the actual costs of implementing the Plan will
not differ materially from the estimated costs or that the
Partnership and its subsidiaries will not be adversely affected
by Year 2000 issues.

   The extent and magnitude of the Year 2000 problem as it may
affect the Partnership and its subsidiaries, both before and for
some period after January 1, 2000, are difficult to predict or
quantify for a number of reasons.  Among the most important is
the potential complexity of locating embedded microprocessors
that may be in a great variety of hardware used for process or
flow control, environmental, transportation, access,
communications and other systems.  The Partnership and its
subsidiaries believe that they will be able to identify and
remediate mission-critical systems containing embedded
microprocessors or will have contingency plans to deal with these
systems.  Other important difficulties relate to the lack of
control over and difficulty inventorying, assessing, remediating,
verifying and testing Outside Systems; the complexity of
evaluating all software (computer code) internal to the
Partnership and its subsidiaries that may not be Year 2000
compatible; and the potential limited availability of certain
necessary internal or external resources, including but not
limited to trained hardware and software engineers, technicians
and other personnel to perform adequate remediation, verification
and testing of internal systems or Outside Systems.  Year 2000
costs are difficult to estimate accurately because of
unanticipated vendor delays, technical difficulties, the impact
of tests of Outside Systems, and similar events.  There can be no
assurance for example that all Outside Systems will be adequately
remediated so that they are Year 2000 ready by January 1, 2000,
or by some earlier date, so as not to create a material
disruption to business.  If, despite diligent, prudent efforts
under the Plan, there are Year 2000-related failures that create
substantial disruptions to the Partnership and its subsidiaries'
businesses, the adverse impact could be material.  Moreover, the
estimated costs of pursuing the current course of action do not
take into account the costs, if any, that might be incurred as a
result of Year 2000-related failures that occur despite
implementation of the Plan, as it may be modified over time.

  In a recent SEC release regarding Year 2000 disclosures,
the SEC stated that public companies must disclose the most
reasonably likely worst case Year 2000 scenario.  Analysis
of the most reasonably likely worst case Year 2000 scenarios
the Partnership may face leads to contemplation of the
following possibilities: widespread failure of electrical,
gas, and similar supplies by utilities serving the
Partnership; widespread disruption of the services of
communications common carriers; similar disruption to means
and modes of transportation for the Partnership and its
employees, contractors, suppliers, and customers;
significant disruption to the Partnership's ability to gain
access to, and remain working in, office buildings and other
facilities; the failure of substantial numbers of the
Partnership's mission-critical information (computer)
hardware and software systems, including both internal
business systems and systems (such as those with embedded
chips) controlling operational facilities such as electrical
generation, transmission, and distribution systems; and the
failure of Outside Systems, the effects of which would have
a cumulative material adverse impact on the Partnership's
mission-critical systems.  Among other things, the
Partnership could face substantial claims due to service
interruptions, inability to fulfill contractual obligations,
inability to account for certain revenues or obligations or
to bill shippers accurately and on a timely basis, and
increased expenses associated with litigation, stabilization
of operations following mission-critical failures, and the
execution of contingency plans.  The Partnership could also
experience an inability by shippers to pay, on a timely
basis or at all, obligations owed to the Partnership.  Under
these circumstances, the adverse effect on the Partnership,
and the diminution of the Partnership's revenues, would be
material, although not quantifiable at this time. The
Partnership will continue to monitor business conditions
with the aim of assessing and quantifying material adverse
effects, if any, that result or may result from the
Year 2000 problem.

Information Regarding Forward Looking Statements

   Statements in this Annual Report that are not historical
information are 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.  Such forward looking statements
include the discussions under "Business-Future Demand and
Competition" and elsewhere regarding Northern Border Pipeline's
efforts to pursue opportunities to further increase its capacity,
the discussion under "Business-Shippers" regarding potential
contract extensions, the discussion under "Business-FERC
Regulation-Cost of Service Tariff" regarding a project cost
containment mechanism related to The Chicago Project and the
discussion in "Management's Discussion and Analysis of Financial
Condition and Results of Operations-Liquidity and Capital
Resources."  Although the Partnership believes that its
expectations regarding future events are based on reasonable
assumptions within the bounds of its knowledge of its business,
it can give no assurance that its goals will be achieved or that
its expectations regarding future developments will be realized.
Important factors that could cause actual results to differ
materially from those in the forward looking statements herein
include industry results, future demand for natural gas,
availability of supplies of Canadian natural gas, political and
regulatory developments that impact FERC proceedings involving
Northern Border Pipeline, Northern Border Pipeline's success in
sustaining its positions in such proceedings or the success of
intervenors in opposing Northern Border Pipeline's positions,
Northern Border Pipeline's ability to replace its rate base as it
is depreciated and amortized, developments relating to the
renewal of the pipeline right-of-way lease within the Fort Peck
Indian Reservation and right-of-way grants involving allotted
lands of the reservation, competitive developments by Canadian
and U.S. natural gas transmission peers, political and regulatory
developments in Canada, conditions of the capital markets and equity
markets, and the Partnership's ability to successfully implement the
Year 2000 Plan during the periods covered by the forward looking
statements.

Item 7a. Quantitative and Qualitative Disclosures About Market Risk

   The Partnership's interest rate exposure results from its
variable rate borrowings from commercial banks.  To mitigate
potential fluctuations in interest rates, the Partnership
maintains a significant portion of its consolidated debt
portfolio in fixed rate debt.  The Partnership also uses interest
rate swap agreements to increase the portion of its fixed rate
debt and uses interest rate forward agreements to establish an
approximate effective borrowing rate for anticipated long-term
debt issuances.

   If interest rates average one percentage point more than rates
in effect as of December 31, 1998, the Partnership's consolidated
annual interest expense would increase by approximately $6.2
million.  This amount has been determined by considering the
impact of the hypothetical interest rates on the Partnership's
variable rate borrowings and interest rate swap agreements
outstanding as of December 31, 1998.  Approximately $5.2 million
of this increase would result from applying the hypothetical
interest rates to Northern Border Pipeline's outstanding debt
portfolio.  Northern Border Pipeline's tariff provides the
pipeline an opportunity to recover, among other items, interest
expense.  Therefore, the Partnership believes that Northern
Border Pipeline would be allowed to recover the increase in its
interest expense, if it were to occur.  Thus, the estimated
impact on the Partnership's annual earnings and cash flow from a
hypothetical one percentage point increase in interest rates
would be a reduction of approximately $1.0 million related to
interest expense on borrowings other than by Northern Border
Pipeline.

Item 8.  Financial Statements and Supplementary Data

   The information required hereunder is included in this report
as set forth in the "Index to Financial Statements" on page F-1.

Item 9.  Disagreements on Accounting and Financial Disclosure

   None.

Item 10. Partnership Management

     The Partnership is managed by or under the direction of the
Partnership Policy Committee consisting of three members, each of
which has been appointed by one of the General Partners.  The
members appointed by Northern Plains, Pan Border and Northwest
Border have 50%, 32.5% and 17.5%, respectively of the voting
power.  The Partnership Policy Committee has appointed two
individuals who are neither officers nor employees of any General
Partner or any affiliate of a General Partner, to serve as a
committee of the Partnership (the "Audit Committee") with
authority and responsibility for selecting the Partnership's
independent public accountants, reviewing the Partnership's
annual audit and resolving accounting policy questions.  The
Audit Committee also has the authority to review, at the request
of a General Partner, specific matters as to which a General
Partner believes there may be a conflict of interest in order to
determine if the resolution of such conflict proposed by the
Partnership Policy Committee is fair and reasonable to the
Partnership.

     As is commonly the case with publicly-traded partnerships,
the Partnership does not directly employ any of the persons
responsible for managing or operating the Partnership or for
providing it with services relating to its day-to-day business
affairs.  The Partnership has entered into an agreement (the
"Administrative Services Agreement") with NBP Services
Corporation ("NBP Services"), a wholly-owned subsidiary of Enron,
pursuant to which NBP Services provides tax, accounting, legal,
cash management, investor relations and other services for the
Partnership.  NBP Services uses the employees of Enron or its
affiliates who have duties and responsibilities other than those
relating to the Administrative Services Agreement.  In
consideration for its services under the Administrative Services
Agreement, NBP Services is reimbursed for its direct and indirect
costs and expenses, including an allocated portion of employee
time and Enron's overhead costs.

     Set forth below is certain information concerning the
members of the Partnership Policy Committee, the Partnership's
representatives on the Northern Border Management Committee and
the persons designated by the Partnership Policy Committee as
executive officers of the Partnership and as Audit Committee
members.  All members of the Partnership Policy Committee and the
Partnership's representatives on the Northern Border Management
Committee serve at the discretion of the General Partner that
appointed them, and the persons designated as executive officers
serve in that capacity at the discretion of the Partnership
Policy Committee.  Effective December 22, 1998, Stanley C. Horton
replaced George L. Mazanec as a member of the Partnership Policy
Committee and the representative on the Northern Border
Management Committee designated by Pan Border.  The members of
the Partnership Policy Committee receive no management fee or
other remuneration for serving on this Committee.  The Audit
Committee members are elected, and may be removed, by the
Partnership Policy Committee.  Each Audit Committee member
receives an annual fee of $15,000 and is paid $1,000 for each
meeting attended.

<FN>
(1) For 1996 and 1997, Mr. Peters' bonus awards were $48,000 and
    $80,000, respectively.  The bonuses detailed exclude amounts
    deferred into the Bonus Stock Option Program.  Mr. Peters
    received a grant of 3,215 options during 1997 in lieu of a
    $20,000 cash bonus payment for 1996 and 4,435 options during
    1998 in lieu of a $32,500 cash bonus payment for 1997.  The
    1998 amount reflects the full bonus earned, including deferrals.

(2) Includes "Perquisites and Other Personal Benefits" if value
    is greater than the lesser of $50,000 or 10% of reported salary
    and bonus.  Also, under Enron's 1985 Deferral Plan, interest is
    credited on amounts deferred based on 150% of Moody's seasoned
    corporate bond yield index with a minimum rate of 12%, which for
    1996, 1997 and 1998 was the minimum rate of 12%.  No interest has
    been reported as Other Annual Compensation under Enron's 1985
    Deferral Plan for participating Named Officers because the
    crediting rates during 1996, 1997 and 1998, did not exceed 120%
    of the long-term Applicable Federal Rate ("AFR") of 14.38% in
    effect at the time the 1985 Deferral Plan was implemented.
    Interest has been reported as Other Annual Compensation under
    Enron's 1994 Deferral Plan during 1996 for the participating Named
    Officers because the crediting rate of 9% exceeded 120% of the
    AFR of 7.29% in effect at the time the 1994 Deferral Plan was
    implemented.  Beginning January 1, 1996, Enron's 1994 Deferral Plan
    credits interest based on fund elections chosen by participants.
    Since earnings on deferred compensation invested in third-party
    investment vehicles, comparable to mutual funds, need not be
    reported, no interest has been reported as Other Annual
    Compensation under Enron's 1994 Deferral Plan during 1996, 1997 and
    1998.  Other Annual Compensation also includes cash perquisite
    allowances.

(3) The aggregate total of shares in unreleased Enron restricted stock
    holdings and their values as of December 31, 1998, for each
    of the Named Officers is:  Mr. DeRoin, 2,191 shares valued at
    $125,024; Mr. Peters, 1,052 shares valued at $60,030.  This
    represents performance based restricted stock which was
    granted in lieu of performance units for the 1999-2002
    performance period.  Assuming continuous employment with Enron
    or an Affiliate, the Award will become vested and will be released
    January 31, 2002 as follows:  (a) 33-1/3% of the total number of
    shares granted will vest and be released if earnings targets,
    as set by the Board of Directors of Enron in its sole discretion,
    are met in any one year of the three year period 1999, 2000 and
    2001, (b) 66-2/3% of the total number of shares granted will vest
    and be released if earnings targets, as set by the Board of
    Directors of Enron in its sole discretion, are met in any two years
    of the three year period 1999, 2000 and 2001, and (c) 100% of
    the Total Number of Shares Granted will vest and be released
    if earnings targets, as set by the Board of Directors of
    Enron in its sole discretion, are met in each of the
    three years or cumulatively over the three year period 1999,
    2000 and 2001.  Shares of Restricted Stock which do not
    become vested according to the above provisions will be
    canceled.

(4) The amount shown for 1996 for Mr. DeRoin represent payouts
    made under Enron's Performance Unit Plan account.

(5) The amounts shown include the value, as of year-end 1996 and
    1998, of Enron Common Stock allocated during those years to
    employees' special subaccounts under Enron's Employee Stock
    Ownership Plan, and 1998 matching contributions to employees'
    Enron Corp. Savings Plan.

(1) If a "change of control" (as defined in the Enron Stock
    Plans) were to occur before the options become exercisable
    and are exercised, the vesting described below will be
    accelerated and all such outstanding options shall be
    surrendered and the optionee shall receive a cash payment by
    Enron in an amount equal to the value of the surrendered
    options (as defined in the Enron Stock Plans).

(2) Represents stock options awarded under the Long-Term
    Incentive Program for 1999.  Grants under this program are
    granted on the last trading day of the prior year, due to
    regulations under Section 162(m) of the Internal Revenue Code.
    Options have a seven year term, and are 25% vested on the date
    of grant with an additional 25% vesting on the anniversary of
    the date of grant through December 31, 2001.

(3) Represents stock options in lieu of 1997 bonus payment in
    January 1998.  Options have a seven year term and immediate
    vesting.

(4) Represents stock options awarded for retention purposes.
    Options have a  ten year term, and are 20% vested on the date
    of grant with an additional 20% vesting on each anniversary
    of the date of grant through October 12, 2002.

(5) An appreciation in stock price, which will benefit all
    stockholders, is required for optionees to receive any gain.
    A stock price appreciation of zero percent would render the
    option without value to the optionees.

(6) The dollar amounts under these columns represent the
    potential realizable value of each grant of options assuming
    that the market price of Common Stock appreciates in value
    from the date of grant at the 5% and 10% annual rates
    prescribed by the SEC and therefore are not intended to
    forecast possible future appreciation, if any, of the price
    of Common Stock.

    Employee Stock Option Program to employees hired during 1998.

(8) Weighted average exercise price of all Enron stock options
    granted to employees in 1998.

(9) Appreciation for All Employee and Director Optionees is
    calculated using the maximum allowable option term of 10
    years, even though in some cases the actual option term is
    less than 10 years.  Appreciation for all stockholders is
    calculated using an assumed ten-year option term, the
    weighted average exercise price for All Employee and Director
    Optionees ($49.9120) and the number of shares of Common Stock
    issued and outstanding on December 31, 1998.

Long-Term Incentive Plan - Awards in 1998

    The following table provides information concerning Long-Term
Incentive Plan awards under the Performance Unit Plan of Enron for
the 1998-2001 performance period.  Grants are made at the beginning
of each fiscal year and each unit is assigned a value of $1.00.
The units are subject to a four-year performance period, at the end
of which Enron's total shareholder return is compared to that of the
11 peer companies included in the Current Peer Group.  At that time,
the units are assigned a value ranging from $0 to $2.00 based on the
rank of Enron's shareholder return within the Current Peer Group.
To be valued at the maximum of $2.00, Enron must rank first, and to be
valued at the target of $1.00, Enron must rank third.  Regardless
of Enron's rank, Enron's shareholder return must be above the
return on 90-day U.S. Treasury Bills over the same performance
period in order for any value to be assigned.

Retirement and Supplemental Benefit Plans

     Enron maintains the Enron Corp. Cash Balance Plan (the "Cash
Balance Plan") which is a noncontributory defined benefit plan to
provide retirement income for employees of Enron and its
subsidiaries.  Through December 31, 1994, participants in the
Cash Balance Plan with five years or more of service were
entitled to retirement benefits in the form of an annuity based
on a formula that uses a percentage of final average pay and
years of service.  In 1995, Enron's Board of Directors adopted an
amendment to and restatement of the Cash Balance Plan changing
the plan's name from the Enron Corp. Retirement Plan to the Enron
Corp. Cash Balance Plan.  In connection with a change to the
retirement benefit formula, all employees became fully vested in
retirement benefits earned through December 31, 1994.  The
formula in place prior to January 1, 1995 was suspended and
replaced with a benefit accrual in the form of a cash balance of
5% of annual base pay beginning January 1, 1996.  Under the Cash
Balance Plan, each employee's accrued benefit will be credited
with interest based on ten-year Treasury Bond yields.

     Enron also maintains a noncontributory employee stock
ownership plan ("ESOP") which covers all eligible employees.
Allocations to individual employees' retirement accounts within
the ESOP offset a portion of benefits earned under the Cash
Balance Plan.  December 31, 1993, was the final date on which
ESOP allocations were made to employees' retirement accounts.

     In addition, Enron has a Supplemental Retirement Plan that
is designed to assure payments to certain employees of that
retirement income that would be provided under the Cash Balance
Plan except for the dollar limitation on accrued benefits imposed
by the Internal Revenue Code of 1986, as amended, and a Pension
Program for Deferral Plan Participants that provides supplemental
retirement benefits equal to any reduction in benefits due to
deferral of salary into Enron's Deferral Plan.

     The following table sets forth the estimated annual benefits
payable under normal retirement at age 65, assuming current
remuneration levels without any salary or bonus projections and
participation until normal retirement at age 65, with respect to
the named officers under the provisions of the foregoing
retirement plans.

<FN>
NOTE: The estimated annual benefits payable are based on the
      straight life annuity form without adjustment for any offset
      applicable to a participant's retirement subaccount in
      Enron's ESOP.
</TABLE>

     Mr. DeRoin participates in the Executive Supplemental
Survivor Benefit Plan.  In the event of death after retirement,
the Plan provides an annual benefit to the participant's
beneficiary equal to 50 percent of the participant's annual base
salary at retirement, paid for 10 years.  The Plan also provides
that in the event of death before retirement, the participant's
beneficiary receives an annual benefit equal to 30% of the
participant's annual base salary at death, paid for the life of
the participant's spouse (but for no more than 20 years in some
cases).

Severance Plans

     Enron's Severance Pay Plan, as amended, provides for the
payment of benefits to employees who are terminated for failing
to meet performance objectives or standards or who are terminated
due to reorganization or economic factors.  The amount of
benefits payable for performance related terminations is based on
length of service and may not exceed six weeks' pay.  For those
terminated as the result of reorganization or economic
circumstances, the benefit is based on length of service and
amount of pay up to a maximum payment of 26 weeks of base pay.
If the employee signs a Waiver and Release of Claims Agreement,
the severance pay benefits are doubled.  Under no circumstances
will the total severance pay benefit exceed 52 weeks of pay.
Under the Enron Corp. Change of Control Severance Plan, in the
event of an unapproved change of control of Enron, any employee
who is involuntarily terminated within two years following the
change of control will be eligible for severance benefits equal
to two weeks of base pay multiplied by the number of full or
partial years of service, plus one month of base pay for each
$10,000 (or portion of $10,000) included in the employee's annual
base pay, plus one month of base pay for each five percent of
annual incentive award opportunity under any approved plan.  The
maximum an employee can receive is 2.99 times the employee's
average W-2 earnings over the past five years.

Item 13.  Certain Relationships and Related Transactions

     The Partnership has extensive ongoing relationships with the
General Partners.  Such relationships include the following: (i)
Northern Plains provides, in its capacity as the operator of the
Pipeline System, certain tax, accounting and other information to
the Partnership, and (ii) NBP Services, an affiliate of Enron,
assists the Partnership in connection with the operation and
management of the Partnership pursuant to the terms of an
Administrative Services Agreement between the Partnership and NBP
Services.

     In addition, Northern Border Pipeline, in which the
Partnership owns a 70% general partner interest, has extensive
ongoing relationships with the General Partners and certain of
their affiliates and with affiliates of TransCanada.  For
example, Northern Plains, a General Partner and affiliate of
Enron, has acted (since 1980), and will continue to act, as the
operator of the Pipeline System pursuant to the terms of an
Operating Agreement between Northern Plains and Northern Border
Pipeline.  Enron Engineering & Construction Company ("EE&CC"),
an affiliate or Enron, provided project management for the
construction of The Chicago Project pursuant to a Project
Management Agreement between Northern Plains and EE&CC.   In
addition, as of February 1, 1999, (i) ECT, an affiliate of Enron,
is a transportation customer of Northern Border Pipeline, which
is obligated to pay 5% of Northern Border Pipeline's annual cost
of service; (ii) Northern Natural, an affiliate of Enron, provides
a financial guaranty for a portion (300 MMCFD) of the transportation
capacity held by PAGUS, which represents 11% of Northern Border
Pipeline's annual cost of service; (iii) TransCanada Gas Services
Inc. ("TransCanada Gas Services"), an affiliate of TransCanada,
is a transportation customer of Northern Border Pipeline which is
obligated to pay 11% of Northern Border Pipeline's annual cost of
service pursuant to a transportation contract with Northern Border
Pipeline wherein TransCanada Gas Services acts as the agent of its
parent, TransCanada and (vi) Transco, an affiliate of Williams, is a
transportation customer of Northern Border Pipeline which is
obligated to pay 1% of Northern Border Pipeline's annual cost of
service.

     The Partnership Policy Committee, whose members are
designated by the three General Partners, establishes the
business policies of the Partnership.  The Partnership has
three representatives on the Northern Border Management
Committee, each of whom votes a portion of the Partnership's
70% interest on the Northern Border Management Committee.
These representatives are also designated by the General Partners.

     The Partnership's interests could conflict with the
interests of the General Partners or their affiliates, and
in such case the members of the Partnership Policy Committee
will generally have a fiduciary duty to resolve such
conflicts in a manner that is in the Partnership's best
interest.  Northern Border Pipeline's interests could
conflict with the Partnership's interest or the interest of
TransCanada and their affiliates, and in such case the
Partnership's representatives on the Northern Border
Management Committee will generally have a fiduciary duty
to resolve such conflicts in a manner that is in the best
interest of Northern Border Pipeline.  The Partnership's
fiduciary duty as a general partner of Northern Border Pipeline
may restrict the Partnership from taking actions that might be
in the Partnership's best interest but in conflict with the
fiduciary duty that the Partnership's representatives or the
Partnership owe to TransCanada.
     
     Unless otherwise provided for in a partnership
agreement, the laws of Delaware and Texas generally require
a general partner of a partnership to adhere to fiduciary
duty standards under which it owes its partners the highest
duties of good faith, fairness and loyalty.  Similar rules
apply to persons serving on the Partnership Policy Committee
or the Northern Border Management Committee.  Because of the
competing interests identified above, the Partnership's
Partnership Agreement and the partnership agreement for
Northern Border Pipeline contain provisions that modify
certain of these fiduciary duties.  For example:
     
     * The Partnership Agreement states that the General
       Partners, their affiliates and their officers and directors
       will not be liable for damages to the Partnership, its
       limited partners or their assignees for errors of judgment
       or for any acts or omissions if the General Partners and
       such other persons acted in good faith.
     * The Partnership Agreement allows the General Partners
       and the Partnership Policy Committee to take into account
       the interests of parties in addition to the Partnership's
       interest in resolving conflicts of interest.
     * The Partnership Agreement provides that the General
       Partners will not be in breach of their obligations under
       the Partnership Agreement or their duties to the Partnership
       or its unitholders if the resolution of a conflict is fair
       and reasonable to the Partnership.  The latitude given in
       the Partnership Agreement in connection with resolving
       conflicts of interest may significantly limit the ability of
       a unitholder to challenge what might otherwise be a breach
       of fiduciary duty.
     * The Partnership Agreement provides that a purchaser of
       Common Units is deemed to have consented to certain
       conflicts of interest and actions of the General Partners
       and their affiliates that might otherwise be prohibited and
       to have agreed that such conflicts of interest and actions
       do not constitute a breach by the General Partners of any
       duty stated or implied by law or equity.
     * The Partnership's Audit Committee will, at the request
       of a General Partner or a member of the Partnership Policy
       Committee, review conflicts of interest that may arise
       between a General Partner and its affiliates (or the member
       of the Partnership Policy Committee designated by it), on
       the one hand, and the unitholders or the Partnership, on the
       other.  Any resolution of a conflict approved by the Audit
       Committee is conclusively deemed fair and reasonable to the
       Partnership.
     * The Partnership has proposed to enter into an amendment
       to the partnership agreement for Northern Border Pipeline
       that relieves TransCanada, its affiliates and their
       transferees from any duty to offer business opportunities to
       Northern Border Pipeline, with certain exceptions.  The
       proposed amendment would also relieve the Partnership from
       any duty to offer to Northern Border Pipeline certain
       business opportunities that come to the Partnership's
       attention.
     
     The Partnership is required to indemnify the members of
the Partnership Policy Committee and General Partners, their
affiliates and their respective officers, directors,
employees, agents and trustees to the fullest extent
permitted by law against liabilities, costs and expenses
incurred by any such person who acted in good faith and in a
manner reasonably believed to be in, or (in the case of a
person other than one of the General Partners) not opposed
to, the Partnership's best interests and with respect to any
criminal proceedings, had no reasonable cause to believe the
conduct was unlawful.

            REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Northern Border Partners, L.P.:

We have audited the accompanying consolidated balance sheets of
Northern Border Partners, L.P., a Delaware limited partnership,
and Subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, cash flows and changes
in partners' capital for each of the three years in the period
ended December 31, 1998.  These financial statements are the
responsibility of the Company's management.  Our responsibility
is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the financial position
of Northern Border Partners, L.P. and Subsidiaries as of December
31, 1998 and 1997, and the results of their operations and their
cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted
accounting principles.

             NORTHERN BORDER PARTNERS, L.P. AND SUBSIDIARIES

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  ORGANIZATION AND MANAGEMENT

    Northern Border Partners, L.P., a Delaware limited partnership,
    through a subsidiary limited partnership, Northern Border Intermediate
    Limited Partnership, a Delaware limited partnership, collectively
    referred to herein as the Partnership, owns a 70% general partner
    interest in Northern Border Pipeline Company (Northern Border Pipeline).
    The remaining 30% general partner interests in Northern Border Pipeline 
    are owned by TransCanada Border PipeLine Ltd. (6%) and TransCan Northern 
    Ltd. (24%), both of which are wholly-owned subsidiaries of TransCanada
    PipeLines Limited (TransCanada).  Black Mesa Holdings, Inc. and
    Black Mesa Pipeline Operations, L.L.C. (collectively Black
    Mesa) and Williams Technologies, Inc. (WTI) are wholly-owned
    subsidiaries of the Partnership (see Note 3).

    Northern Plains Natural Gas Company (Northern Plains), a
    wholly-owned subsidiary of Enron Corp. (Enron), Pan
    Border Gas Company (Pan Border), a wholly-owned subsidiary of
    Northern Plains, and Northwest Border Pipeline Company (Northwest
    Border), a wholly-owned subsidiary of The Williams Companies, Inc.
    serve as the General Partners of the Partnership and collectively
    own a 2% general partner interest in the Partnership.  In December
    1998, Northern Plains acquired Pan Border from a subsidiary of Duke
    nergy Corporation.  At the closing, Pan Border's sole asset consisted
    of its general partner interest in the Partnership.  The General
    Partners or their affiliates also own Subordinated Units representing,
    in the aggregate, an effective 14.5% limited partner interest in the
    Partnership at December 31, 1998 (see Note 6).

    The Partnership is managed by or under the direction of a committee
    (Partnership Policy Committee) consisting of one person appointed by
    each General Partner.  The members appointed by Northern Plains, Pan
    Border and Northwest Border have 50%, 32.5% and 17.5%, respectively,
    of the voting interest on the Partnership Policy Committee.  The
    Partnership has entered into an administrative services agreement
    with NBP Services Corporation (NBP Services), a wholly-owned
    subsidiary of Enron, pursuant to which NBP Services provides certain
    administrative services for the Partnership and is reimbursed for
    its direct and indirect costs and expenses.

    Northern Border Pipeline is a general partnership, formed March 9,
    1978, pursuant to the Texas Uniform Partnership Act.  Northern
    Border Pipeline owns a 1,214-mile natural gas transmission pipeline
    system extending from the United States-Canadian border near Port of
    Morgan, Montana, to a terminus near Manhattan, Illinois.

    Northern Border Pipeline is managed by a Management Committee that
    includes three representatives from the Partnership (one
    representative appointed by each of the General Partners of the
    Partnership) and one representative from the TransCanada subsidiaries.
    The Partnership's representatives selected by Northern Plains, Pan
    Border and Northwest Border have 35%, 22.75% and 12.25%, respectively,
    of the voting interest on the Northern Border Pipeline Management
    Committee.  The representative designated by TransCanada votes the
    remaining 30% interest.  The day-to-day management of Northern
    Border Pipeline's affairs is the responsibility of Northern Plains
    (the Operator), as defined by the operating agreement between
    Northern Border Pipeline and Northern Plains.  Northern Border
    Pipeline is charged for the salaries, benefits and expenses of the
    Operator.  Substantially all of the operations and maintenance
    expenses are paid to the Operator and other Enron affiliates.
    Additionally, an Enron affiliate was responsible for project
    management on Norther Border Pipeline's expansion and extension
    of its pipeline from near Harper, Iowa to a point near Manhattan,
    Illinois (The Chicago Project) (see Note 7).

    The Northern Border Pipeline partnership agreement provides that
    distributions to Northern Border Pipeline's partners are to be made
    on a pro rata basis according to each partner's capital account
    balance.  The Northern Border Pipeline Management Committee
    determines the amount and timing of such distributions.  Any changes
    to, or suspension of, the cash distribution policy of Northern
    Border Pipeline requires the unanimous approval of the Northern
    Border Pipeline Management Committee.

    Black Mesa, through a wholly-owned subsidiary, owns a 273-
    mile, 18-inch diameter coal slurry pipeline that originates at a coal
    mine in Kayenta, Arizona and ends at the 1,500 megawatt Mohave Power
    Station located in Laughlin, Nevada.  A subsidiary of the Partnership is
    the operator of Black Mesa, pursuant to a management agreement.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (A) Principles of Consolidation and Use of Estimates

        The consolidated financial statements include the assets,
        liabilities and results of operations of the Partnership and its
        majority-owned subsidiaries.  The Partnership operates through a
        subsidiary limited partnership of which the Partnership is the
        sole limited partner and the General Partners are the sole
        general partners.  The 30% ownership of Northern Border Pipeline
        by the TransCanada subsidiaries is accounted for as a minority
        interest.  All significant intercompany items have been eliminated
        in consolidation.

        The preparation of financial statements in conformity with
        generally accepted accounting principles requires management to
        make estimates and assumptions that affect the reported amounts
        of assets and liabilities and disclosure of contingent assets
        and liabilities at the date of the financial statements and the
        reported amounts of revenues and expenses during the reporting
        period.  Actual results could differ from those estimates.

    (B) Government Regulations

        Northern Border Pipeline is subject to regulation by the
        Federal Energy Regulatory Commission (FERC).  Northern Border
        Pipeline's accounting policies conform to generally accepted
        accounting principles, as applied in the case of regulated
        entities.

    (C) Revenue Recognition

        Northern Border Pipeline bills the cost of service on an
        estimated basis for a six-month cycle.  Any net excess or deficiency
        resulting from the comparison of the actual cost of service determined
        for that period in accordance with the FERC tariff to the estimated
        billing is accumulated, including carrying charges thereon, and is
        either billed to or credited back to the shippers.  Revenues reflect
        actual cost of service.  An amount equal to differences between billing
        estimates and the actual cost of service, including carrying charges, is
        reflected in current assets or current liabilities.

    (D) Income Taxes

        Income taxes are the responsibility of the partners and are
        not reflected in these financial statements.  However, the
        Northern Border Pipeline tariff establishes the method of
        accounting for and calculating income taxes and requires
        Northern Border Pipeline to reflect in its cost of service the
        income taxes which would have been paid or accrued if Northern
        Border Pipeline were organized during the period as a
        corporation.  As a result, for purposes of calculating the
        return allowed by the FERC, partners' capital and rate base are
        reduced by the amount equivalent to the net accumulated deferred
        income taxes.  Such amounts were approximately $300 million at
        both December 31, 1998 and 1997, and are primarily related to
        accelerated depreciation and other plant-related differences.

    (E) Property, Plant and Equipment and Related Depreciation and
        Amortization

        Property, plant and equipment is stated at original cost.
        Balances at December 31, 1998 and 1997 include construction work
        in progress of approximately $1.5 million and $211.4 million,
        respectively.  Approximately $197.9 million of construction work
        in progress at December 31, 1997, represented project-to-date
        costs on The Chicago Project.  In December 1998, Northern Border
        Pipeline placed into service the facilities for The Chicago
        Project.  At December 31, 1998 and 1997, respectively,
        approximately $37.4 million and $44.2 million of project costs
        incurred but not paid for The Chicago Project were recorded in
        accounts payable and property, plant and equipment on the
        consolidated balance sheet and were excluded from the
        changes in other current assets and liabilities and capital
        expenditures for property, plant and equipment, net on the
        consolidated statement of cash flows.

        Maintenance and repairs are charged to operations in the
        period incurred.  The provision for depreciation and
        amortization of Northern Border Pipeline's transmission line is
        an integral part of its FERC tariff.  The effective depreciation
        rate applied to Northern Border Pipeline's gross transmission
        plant in 1998, 1997, and 1996 was 2.5%, 2.5%, and 3.1%,
        respectively (see Note 7).  At the time The Chicago Project was
        placed into service, Northern Border Pipeline's depreciation
        rate was reduced to 2.0%.  Beginning in the year 2000, the
        depreciation rate is scheduled to increase gradually on an
        annual basis until it reaches 3.2% in 2002.  Composite rates are
        applied to all other functional groups of property having
        similar economic characteristics.

        The original cost of property retired is charged to
        accumulated depreciation and amortization, net of salvage and
        cost of removal.  No retirement gain or loss is included in
        income except in the case of extraordinary retirements or sales.

    (F) Cash and Cash Equivalents
        
        Cash equivalents consist of highly liquid investments with
        original maturities of three months or less.  The carrying
        amount of cash and cash equivalents approximates fair value
        because of the short maturity of these investments.

    (G) Allowance for Funds Used During Construction

        The allowance for funds used during construction (AFUDC)
        represents the estimated costs, during the period of
        construction, of funds used for construction purposes.  For
        regulated activities, Northern Border Pipeline is permitted to
        earn a return on and recover AFUDC through its inclusion in rate
        base and the provision for depreciation.  The rate employed for
        the equity component of AFUDC is the equity rate of return
        stated in Northern Border Pipeline's FERC tariff.

    (H) Risk Management

        Financial instruments are used by Northern Border Pipeline in
        the management of its interest rate exposure.  A control
        environment has been established which includes policies and
        procedures for risk assessment and the approval, reporting and
        monitoring of financial instrument activities.  As a result,
        Northern Border Pipeline has entered into various interest rate
        swap agreements with major financial institutions which hedge
        interest rate risk by effectively converting certain of its
        floating rate debt to fixed rate debt.  Additionally, Northern
        Border Pipeline has entered into interest rate forward
        agreements to hedge the interest rates on a planned issuance
        of fixed rate debt.  Northern Border Pipeline does not use these
        instruments for trading purposes.  The cost or benefit of the
        interest rate swap agreements is recognized currently as a
        component of interest expense.  No cost or benefit is currently
        associated with the interest rate forward agreements.

    (I) Reclassifications

        Certain reclassifications have been made to the consolidated
        financial statements for prior years to conform with the current
        presentation.

3.  ACQUISITIONS

          On May 31, 1997, the Partnership exchanged 125,357 Common
     Units for all of the outstanding common stock of WTI.  Effective
     with the acquisition of WTI, which was recorded using the purchase
     method of accounting, the Partnership increased its ownership
     position in Black Mesa from the 60.5% acquired in 1996 to 71.75%
     and began to reflect Black Mesa, including Black Mesa's minority
     ownership interests, in the Partnership's consolidated financial
     statements.  Prior to this time, the Partnership's investment in
     Black Mesa was accounted for using the equity method.  On December
     29, 1997, the Partnership acquired the remaining minority ownership
     interest in Black Mesa through the exchange of 46,956 Common Units
     and cash.  The following is a summary of the effects of the
     acquisition of WTI and consolidation of Black Mesa on the
     Partnership's consolidated financial position in 1997 (amounts
     in thousands):

4.  SHIPPER SERVICE AGREEMENTS

    Operating revenues are collected pursuant to the FERC tariff which
    directs that Northern Border Pipeline collect its cost of service
    through firm transportation service agreements (firm service
    agreements).  Northern Border Pipeline's FERC tariff provides an
    opportunity to recover all operations and maintenance costs of the
    pipeline, taxes other than income taxes, interest, depreciation and
    amortization, an allowance for income taxes and a regulated equity
    return.  Billings for the firm service agreements are based on
    contracted volumes to determine the allocable share of the cost of
    service and are not dependent upon the percentage of available
    capacity actually used.

    Northern Border Pipeline's firm service agreements extend for
    various terms with termination dates that range from October 2001 to
    December 2013.  Northern Border Pipeline also has interruptible
    service contracts with numerous other shippers as a result of its
    self-implementing blanket transportation authority.  Revenues
    received from the interruptible service contracts are credited to
    the cost of service reducing the billings for the firm service
    agreements.

    Northern Border Pipeline's largest shipper, Pan-Alberta Gas (U.S.)
    Inc. (PAGUS), is presently obligated for approximately 26.5% of the
    cost of service through three firm service agreements which expire
    in October 2003.  FERC approval is required for the extension of one
    of the firm service agreements, relating to approximately 6.5% of
    the cost of service, beyond October 2001.  Financial guarantees
    exist through October 2001 for approximately 17.0% of the total cost
    of service related to the contracted capacity of PAGUS, including
    10.5% guaranteed by Northern Natural Gas Company, a wholly-owned
    subsidiary of Enron.  The remaining cost of service obligation of
    PAGUS is supported by various credit support arrangements, including
    among others, a letter of credit, an escrow account and an upstream
    capacity transfer agreement.  Operating revenues from the PAGUS firm
    service agreements and interruptible service contracts for the years
    ended December 31, 1998, 1997 and 1996 were $87.3 million, $86.8
    million and $95.7 million, respectively.

    Shippers affiliated with the partners of Northern Border Pipeline
    have firm service agreements representing approximately 16.9% of the
    cost of service.  These firm service agreements extend for various
    terms with termination dates that range from October 2003 to May
    2009.  Operating revenues from the affiliated firm service
    agreements and interruptible service contracts for the years ended
    December 31, 1998, 1997 and 1996 were $22.4 million, $20.2 million
    and $21.4 million, respectively.

    Black Mesa's operating revenue is derived from a pipeline
    transportation agreement (Pipeline Agreement) with the coal supplier
    for the Mohave Power Station that expires in December 2005.  The
    pipeline is the sole source of fuel for the Mohave plant.  Under the
    terms of the Pipeline Agreement, the pipeline receives a monthly
    demand payment, a per ton commodity payment and a reimbursement for
    certain other expenses.

</TABLE>

    In June 1997, Northern Border Pipeline entered into a credit
    agreement (Pipeline Credit Agreement) with certain financial
    institutions to borrow up to an aggregate principal amount of $750
    million.  The Pipeline Credit Agreement is comprised of a $200
    million five-year revolving credit facility to be used for the
    retirement of Northern Border Pipeline's existing bank loan
    agreement and for general business purposes, and a $550 million
    three-year revolving credit facility to be used for the construction
    of The Chicago Project.  The three-year revolving credit facility
    may be converted to a term loan maturing in June 2002 once certain
    conditions are met.  The Pipeline Credit Agreement permits Northern
    Border Pipeline to choose among various interest rate options, to
    specify the portion of the borrowings to be covered by specific
    interest rate options and to specify the interest rate period,
    subject to certain parameters.  Northern Border Pipeline is required
    to pay a facility fee on the aggregate principal amount of $750
    million.

    At both December 31, 1998 and 1997, Northern Border Pipeline had
    outstanding interest rate swap agreements with notional amounts of
    $90 million.  Under the agreements, which have a remaining average
    maturity of approximately one year as of December 31, 1998, Northern
    Border Pipeline makes payments to counterparties at fixed rates and
    in return receives payments at variable rates based on the London
    Interbank Offered Rate.  At both December 31, 1998 and 1997,
    Northern Border Pipeline was in a payable position relative to its
    counterparties.  The average effective interest rate of Northern
    Border Pipeline's variable rate debt, taking into consideration the
    interest rate swap agreements, was 6.17% and 7.09% at December 31,
    1998 and 1997, respectively.

    During September 1998, Northern Border Pipeline executed interest
    rate forward agreements with an aggregate notional amount of $150
    million to hedge the interest rate for a planned issuance of fixed
    rate debt during 1999.  The average reference interest rate on the
    agreements, based on ten-year U.S. Treasury Notes, is 4.90%.

    In November 1997, the Partnership entered into a credit agreement
    (Partnership Credit Agreement) with certain financial institutions
    to borrow up to an aggregate principal amount of $175 million under
    a revolving credit facility.  The Partnership Credit Agreement is to
    be used for interim funding of the Partnership's required capital
    contributions to Northern Border Pipeline for construction of The
    Chicago Project.  The amount available under the Partnership Credit
    Agreement is reduced to the extent the Partnership issues additional
    limited partner interests to fund the Partnership's required capital
    contributions for The Chicago Project in excess of $25 million.  The
    public offering of Common Units discussed in Note 6 reduced the
    amount available under the Partnership Credit Agreement to $104
    million at December 31, 1998.  The maturity date of the Partnership
    Credit Agreement will be November 2000 if Northern Border Pipeline
    converts the $550 million three-year revolving credit facility to a
    term loan; otherwise the maturity date is June 2000.  The
    Partnership Credit Agreement permits the Partnership to choose among
    various interest rate options, to specify the portion of the
    borrowings to be covered by specific interest rate options and to
    specify the interest rate period, subject to certain parameters.
    The Partnership is required to pay a commitment fee on the aggregate
    undrawn principal amount under the facility.  At December 31, 1998,
    the average interest rate on the Partnership Credit Agreement was
    6.04%.

    Interest paid, net of amounts capitalized, during the years
    ended December 31, 1998, 1997 and 1996 was $28.7 million, $31.6
    million and $31.9 million, respectively.

    Aggregate repayments of long-term debt required for the next five
    years are as follows:  $3 million, $164 million, $44 million, $694
    million and $69 million for 1999, 2000, 2001, 2002 and 2003,
    respectively.  The aggregate repayments reflect Northern Border
    Pipeline's intent and ability to convert the three-year revolving
    credit facility to a term loan.

    Certain of Northern Border Pipeline's long-term debt and credit
    arrangements contain requirements as to the maintenance of minimum
    partners' capital and debt to capitalization ratios which restrict
    the incurrence of other indebtedness by Northern Border Pipeline and
    also place certain restrictions on distributions to the partners of
    Northern Border Pipeline.  Under the most restrictive of the
    covenants, as of December 31, 1998 and 1997, respectively, $173
    million and $81 million of partners' capital of Northern Border
    Pipeline could be distributed.  The Partnership Credit Agreement
    restricts incurrence of senior indebtedness by the Partnership and
    requires the maintenance of a ratio of debt to total capital,
    excluding the debt of consolidated subsidiaries, of no more than 35
    percent.  Black Mesa's note agreement is secured by the common stock
    of Black Mesa and by a guarantee by the Partnership of up to $1.0
    million.  In addition, the note agreement requires Black Mesa to
    maintain a deposit of $2.0 million, invested in Treasury bills, in
    escrow until the debt is retired.  The deposit is reflected in other
    assets on the consolidated balance sheet at December 31, 1998 and
    1997.

    The following estimated fair values of financial instruments
    represent the amount at which each instrument could be exchanged in
    a current transaction between willing parties.  Based on quoted
    market prices for similar issues with similar terms and remaining
    maturities, the estimated fair value of the senior notes was
    approximately $287 million and $276 million at December 31, 1998 and
    1997, respectively.  The estimated fair value of the Black Mesa note
    agreement was approximately $23 million and $25 million at December
    31, 1998 and 1997, respectively.  At both December 31, 1998 and
    1997, the estimated fair value which would be payable to terminate
    the interest rate swap agreements, taking into account current
    interest rates, was approximately $3 million.  The estimated fair
    value which would be payable to terminate the interest rate forward
    agreements, taking into account current interest rates, was
    approximately $3 million at December 31, 1998.  The Partnership
    presently intends to maintain the current schedule of maturities for
    the senior notes, the Black Mesa note agreement and the interest
    rate swap agreements that will result in no gains or losses on their
    respective repayment.  The carrying value of the Pipeline Credit
    Agreement approximates the fair value since the interest rates are
    periodically adjusted to current market conditions.

6.  PARTNERS' CAPITAL

    At December 31, 1998, partners' capital consisted of 22,927,313
    Common Units representing an effective 76.6% limited partner
    interest in the Partnership; 6,420,000 Subordinated Units
    representing an effective 21.4% limited partner interest in the
    Partnership (including the 14.5% held collectively by the General
    Partners or their affiliates); and a 2% general partner interest.
    At December 31, 1997, partners' capital consisted of 22,702,313
    Common Units representing an effective 76.4% limited partner
    interest in the Partnership; 6,420,000 Subordinated Units
    representing an effective 21.6% limited partner interest in the
    Partnership; and a 2% general partner interest.  In January 1998 and
    December 1997, the Partnership sold, through an underwritten public
    offering, 225,000 Common Units and 2,750,000 Common Units,
    respectively.  The units sold in 1998 resulted from the underwriters
    exercise of an over-allotment option to purchase a limited number of
    additional Common Units.  In conjunction with the issuance of the
    additional Common Units, the Partnership's general partners made
    capital contributions to the Partnership to maintain a 2% general
    partner interest in accordance with the partnership agreements.
    The net proceeds, of the public offering and the general partners'
    capital contributions, of approximately $7.6 million and $90.9
    million in 1998 and 1997, respectively, were used by the Partnership
    to fund a portion of the capital contributions to Northern Border
    Pipeline for construction of The Chicago Project.

    The Partnership will make distributions to its partners with respect
    to each calendar quarter in an amount equal to 100% of its Available
    Cash.  "Available Cash" generally consists of all of the cash
    receipts of the Partnership adjusted for its cash disbursements and
    net changes to cash reserves.  Available Cash will generally be
    distributed 98% to the Unitholders and 2% to the General Partners.
    The holders of Units are entitled to receive the minimum quarterly
    distribution of $0.55 per Unit per quarter if and to the extent
    there is sufficient Available Cash.  Distributions of Available Cash
    to the holders of Subordinated Units are subject, while the
    Subordinated Units remain outstanding, to the rights of the holders
    of the Common Units to receive the minimum quarterly distribution.
    The Partnership Policy Committee determined the subordination period
    ended as a result of satisfying the criteria set forth in the
    partnership agreement.  The holders of Subordinated Units are no
    longer subordinated to the rights of the holders of Common Units
    to receive quarterly distributions and the 6,420,000 outstanding
    Subordinated Units have been converted into an equal number of
    Common Units effective January 19, 1999.

    Partnership income is allocated to the General Partners and the
    limited partners in accordance with their respective partnership
    percentages, after giving effect to any priority income allocations
    for incentive distributions that are allocated 100% to the General
    Partners.  As an incentive, the General Partners' percentage
    interest in quarterly distributions is increased after certain
    specified target levels are met.  At the time the quarterly
    distributions exceed $0.605 per Unit, the General Partners receive
    15% of the excess.  As the quarterly distributions are increased
    above $0.715 per Unit, the General Partners receive increasing
    percentages in excess of the targets reaching a maximum of 50% of
    the excess of the highest target level (see Note 11).

7.  COMMITMENTS AND CONTINGENCIES

    Regulatory Proceedings

    In October 1998, Northern Border Pipeline filed a certificate
    application with the FERC to seek approval to expand and extend its
    pipeline system into Indiana by November 2000 (Project 2000).
    Project 2000 would afford shippers on the extended pipeline system
    access to industrial gas consumers in northern Indiana.  Project
    2000 capital expenditures are estimated at $130 million.

    In January 1998, Northern Border Pipeline filed an application with
    the FERC to acquire the linepack gas required to operate the
    pipeline from the shippers and to provide the linepack gas in the
    future for its operations.  The cost of the linepack gas acquired in
    1998, which is included in rate base, totaled approximately $11.7
    million.

    In August 1997, Northern Border Pipeline received FERC approval of a
    Stipulation and Agreement (Stipulation) filed on October 15, 1996 to
    settle its November 1995 rate case.  Northern Border Pipeline filed
    the rate case, in compliance with its FERC tariff, for the
    determination of its allowed equity rate of return and was
    permitted, pursuant to a December 1995 FERC order, to begin
    collecting the requested increase in the equity rate of return
    effective June 1, 1996, subject to refund.  In accordance with the
    terms of the Stipulation, Northern Border Pipeline's allowed equity
    rate of return was reduced from the requested 14.25% to 12.75% for
    the period June 1, 1996 to September 30, 1996 and to 12% thereafter.
    Additionally, the Stipulation reduced the effective depreciation
    rate applied to Northern Border Pipeline's gross transmission plant
    from 3.6% to 2.7% for the period June 1, 1996 to December 31, 1996,
    which resulted in an average effective depreciation rate of 3.1% for
    the year ended December 31, 1996.  Beginning January 1, 1997, the
    depreciation rate was reduced to 2.5%.  In October 1997, Northern
    Border Pipeline used a combination of cash on hand and borrowings on
    a revolving credit facility to pay refunds to its shippers of
    approximately $52.6 million.  Under the terms of the Stipulation,
    Northern Border Pipeline agreed to further reduce its depreciation
    rate to 2.0% and agreed to implement a $31 million settlement
    adjustment mechanism (SAM) when The Chicago Project was placed in
    service.  The SAM effectively reduces the allowed return on rate
    base.
     
    Also as agreed to in the Stipulation, Northern Border Pipeline
    implemented a capital project cost containment mechanism (PCCM).
    The purpose of the PCCM was to limit Northern Border Pipeline's
    ability to include cost overruns on The Chicago Project in rate base
    and to provide incentives to Northern Border Pipeline for cost
    underruns.  The PCCM amount is determined by comparing the final
    cost of The Chicago Project to the budgeted cost.  The Stipulation
    required the budgeted cost for The Chicago Project, which had been
    initially filed with the FERC for approximately $839 million, to be
    adjusted for the effects of inflation and project scope changes, as
    defined in the Stipulation.  Such adjusted budgeted cost has been
    estimated as of the in service date to be $889 million, with the
    final construction cost estimated to be $892 million.  Thus, Northern
    Border Pipeline's report to the FERC and its shippers in late December
    1998, reflected the conclusion that, based on information as of that
    date, once the budgeted cost has been established, there would be no
    adjustment to rate base as a result of the PCCM.  Northern Border
    Pipeline is obligated by the Stipulation to update its calculation
    of the PCCM six months after the in service date of The Chicago
    Project.  The Stipulation requires the calculation of the PCCM to be
    reviewed by an independent national accounting firm.  Several
    parties to the Stipulation advised the FERC that they may have
    questions and desire further information about the report, and may
    possibly wish to test it (or the final report) and its conclusions
    in an appropriate proceeding in the future.  The parties also stated
    that if it is determined that Northern Border Pipeline is not permitted
    to include certain claimed costs for The Chicago Project in its rate
    base, they reserve their rights to seek refunds, with interest, of
    any overcollections.  Although the Partnership believes the initial
    computation has been made in accordance with the terms of the
    Stipulation, it is unable to make a definitive determination at this
    time whether any adjustments will be required.  Should subsequent
    developments cause costs not to be recovered pursuant to the PCCM,
    a non-cash charge to write down transmission plant may result and
    such charge could be material to the operating results of the
    Partnership.

    During the construction of The Chicago Project, Northern Border
    Pipeline placed certain new facilities into service in advance of
    the December 1998 in service date to maintain gas flow at firm
    contracted capacity while existing facilities were being modified.
    As required by the certificate of public convenience and necessity
    issued by the FERC, Northern Border Pipeline recorded a regulatory
    credit of approximately $8.9 million in 1998, which is reflected on
    the consolidated statement of income.  The regulatory credit results
    in a deferral of the cost of service of these new facilities.  The
    regulatory asset that resulted from the cost of service deferral is
    included in Other Assets on the consolidated balance sheet.
    Northern Border Pipeline is allowed to recover the regulatory asset
    from its shippers over a ten-year period commencing with the in
    service date of The Chicago Project.

    Environmental Matters

    The Partnership is not aware of any material contingent liabilities
    with respect to compliance with applicable environmental laws and
    regulations.

    Other

    Various legal actions that have arisen in the ordinary course of
    business are pending.  The Partnership believes that the resolution
    of these issues will not have a material adverse impact on the
    Partnership's results of operations or financial position.

8.  CAPITAL EXPENDITURE PROGRAM

    Total capital expenditures for 1999 are estimated to be $131
    million.  This includes approximately $30 million for Project 2000
    (see Note 7), approximately $85 million for The Chicago Project and
    approximately $16 million for renewals and replacements of the
    existing facilities.  Approximately $37 million of the capital
    expenditures for The Chicago Project is for construction completed
    in 1998.  Funds required to meet the 1999 capital expenditures are
    anticipated to be provided primarily from debt borrowings and
    internal sources.

9.  NET INCOME PER UNIT

    The General Partners' allocation of net income is based on their
    combined 2% interest in the Partnership which has been deducted
    before calculating net income per Unit.  The computation of net
    income per Unit is based on the weighted average number of
    outstanding Common Units and Subordinated Units.
