NOTES TO THE FINANCIAL STATEMENTS

(unaudited)

1.  Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with United States generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, they contain all adjustments which management considers
necessary to present fairly the financial position as at June 30, 2000 and December 31, 1999; the results of operations for the three and six month periods ended June 30, 2000 and
1999; and cash flows for the six month periods ended June 30, 2000 and 1999. The results of operations for the six months ended June 30, 2000 should not be taken as indicative of the
results to be expected for the full year. The interim financial statements should be read in conjunction with the Partnership's financial statements and notes thereto presented in the Partnership's
1999 Annual Report on Form 10-K.

2.  Comparative Amounts

Certain comparative amounts are reclassified to conform with the current period's financial statement presentation.

3.  Accrued Rate Refunds and Related Interest

In October 1996, the Federal Energy Regulatory Commission ("FERC") approved a settlement agreement between the Partnership and customer representatives
on all then outstanding contested tariff rates. The agreement resulted in an approximate tariff rate reduction of 6% and total rate refunds and related interest of $120.0 million through the
effective date of October 1, 1996. Refunds required under the agreement began in 1996 with $41.8 million repaid during the fourth quarter of 1996, with the balance repaid through a 10%
reduction in tariff rates. Interest was accrued on the unpaid balance based on the 90-day Treasury Bill rate. Effective November 22, 1999, the 10% reduction in tariff rates was
removed and during December 1999, the $120.0 million and related interest was fully repaid.

4.  Environmental Contingencies

The Partnership is subject to federal and state laws and regulations relating to the protection of the environment. Environmental risk is inherent to liquid
pipeline operations and the Partnership could, at times, be subject to environmental cleanup and enforcement actions. The General Partner manages this environmental risk through appropriate
environmental policies and practices to minimize the impact to the Partnership. To the extent the Partnership is unable to recover environmental costs in its rates (if not recovered through
insurance), the General Partner has agreed to indemnify the Partnership from and against any costs relating to environmental liabilities associated with the pipeline system prior to its transfer to
the Partnership in 1991. This excludes any liabilities resulting from a change in laws after such transfer. The Partnership continues to voluntarily investigate past leak sites for the purpose of
assessing whether any remediation is required in light of current regulations, and to date no material environmental risks have been identified.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

Six Months Ended June 30, 2000 Compared with Six Months Ended June 30, 1999

Net income for the six months ended June 30, 2000, was $37.0 million, compared to $44.7 million for the same period in 1999. The decline
in net income for the first half reflects higher operating and administrative expenses, depreciation and interest expense, which were partially offset by higher operating revenue and lower power
costs.

Operating
revenue for the first six months of 2000 increased $2.7 million, to $157.1 million, over the corresponding period in 1999 as declines in deliveries were more
than offset by increased tariffs related
to the System Expansion Project II ("SEP II") and the Terrace Expansion Project ("Terrace"). Deliveries averaged 1.361 million barrels per day for the first six months of 2000,
compared to 1.386 million barrels per day for the same period of 1999. The reduction stems primarily from the lag in recovery of crude oil production in western Canada, which impacts volumes
available for transport on the Lakehead System. Crude oil production in western Canada was impacted by the low world crude oil prices in 1998 and early 1999, which caused drilling and production
activity in western Canada to drop to its lowest level since 1993. See "GeneralFuture Prospects".

Total
operating expenses for the first six months of 2000 increased $6.8 million from the corresponding period last year. The increase resulted from higher operating and
administrative and depreciation costs, offset by lower power costs. Operating and administrative costs increased $6.7 million primarily due to increases in property taxes associated with the
recent expansion projects and oil measurement losses. Depreciation expense increased $2.4 million primarily as a result of Terrace, which was put into service in April 1999. Power costs
decreased $2.3 million due to lower deliveries.

Interest
expense for the first six months of 2000 was $3.7 million higher than the same period of 1999 due to lower capitalized interest associated with the recent expansion
projects.

Three Months Ended June 30, 2000 Compared with Three Months Ended June 30, 1999

Net income for the three months ended June 30, 2000, was $16.7 million, compared to $22.7 million for the same period last year. The
decline in quarterly results reflects lower operating revenue and higher operating and interest expenses.

Operating
revenue for the second quarter of 2000 was $78.3 million, a decrease of $2.1 million over the corresponding period in 1999, due to declines in deliveries and a
reduction in tariff rates from the annual index adjustment in July 1999. Deliveries averaged 1.358 million barrels per day for the second quarter of 2000, compared to
1.376 million barrels per day for the same period of 1999. As previously noted, the reduction stems primarily from the lag in recovery of crude oil production in western Canada.

Total
operating expenses for the three months ended June 30, 2000, increased by $2.1 million from the corresponding period in 1999. Decreased power costs of
$1.3 million were offset by higher operating and administrative expenses of $2.8 million, and higher depreciation costs of $0.6 million. Power costs declined due to lower
deliveries. Operating and administrative costs increased due to higher property
taxes associated with the recent expansions and oil measurement losses. Depreciation expense increased due to placing Terrace in service April 1, 1999.

As
previously noted, interest expense for the second quarter of 2000 was $1.8 million higher than the same period of 1999 due to lower capitalized interest once major project
construction was completed last year.

The results of operations for the three month and six month periods ended June 30, 2000 should not be taken as indicative of the results of operations expected for the full
year.

Liquidity and Capital Resources

The Partnership anticipates that it will continue to have adequate liquidity to fund future recurring operating, investing and financing activities. The
Partnership intends to fund ongoing capital expenditures with borrowings, cash generated from operating activities, existing cash and cash equivalents and the proceeds from future partner capital
contributions and debt offerings. Cash distributions are expected to be funded with internally generated cash. The Partnership's ability to make future debt offerings and receive partner capital
contributions will depend on prevailing market conditions, interest rates and the financial condition of the Partnership.

At
June 30, 2000, cash and cash equivalents totaled $37.1 million, as compared to $40.0 million at December 31, 1999. Of this $37.1 million,
$27.9 million will be used for the cash distribution payable August 14, 2000, with the remaining $9.2 million available for capital expenditures or other business needs.

Cash
flow from operating activities for first six months of 2000 was $57.1 million, as compared with $44.7 million for the same period last year. The majority of this
increase, $15.2 million, is attributable to the elimination of the rate refunds related to the 1996 settlement agreement. The rate refund obligation was fully repaid during 1999 and the 10%
tariff credit was cancelled effective November 22, 1999.

The
Partnership anticipates spending approximately $13.0 million for pipeline system enhancements and $12.0 million for core maintenance activities in 2000. Excluding
major expansion projects, ongoing capital expenditures are expected to average approximately $20.0 million on an annual basis (approximately 50% for core maintenance and 50% for enhancement of
the pipeline system). Core maintenance activities, such as the replacement of equipment and preventive maintenance programs, will be undertaken to enable the Partnership's pipeline system to continue
to operate at its maximum operating capacity. Enhancements to the pipeline system, such as renewal and replacement of pipe, are expected to extend the life of the Lakehead System and permit the
Partnership to respond to developing industry and government standards and the changing service expectations of its customers.

General

Future Prospects

Income and cash flows of the Partnership are sensitive to oil industry supply and demand in Canada and the United States and the regulatory environment. As the
Partnership's pipeline system is operationally integrated with the Enbridge Pipelines System in western Canada, the Partnership's revenues are dependent upon the utilization of the Enbridge Pipelines
System by producers of western Canadian crude oil. The Partnership believes the long-term demand for its pipeline system will continue.

The
outlook for future growth is believed to be positive for the Partnership. Although crude oil prices have been strong for the past year, exploration and production activity lagged,
as producers of western Canadian crude oil were cautious to invest in new production. Total crude oil production in the western Canadian region declined in excess of 200,000 barrels per day due to the
curtailment of exploration and production activity. During the last few months, production has increased modestly and the outlook is for continuing growth. As a leading indicator for crude oil
production, oil well completions have more than tripled from last year, as approximately 2,500 wells were completed in the first six months of 2000 compared with 700 wells during the same
period last year. Although there has been a bias toward natural gas drilling, crude oil exploration is now on the rise and this trend is expected to continue through 2000. This resurgence is also
supported by external forecasts for oil prices over the next several years. Forecasts for the West Texas Intermediate crude oil benchmark are in the
low-to-mid-twenty dollar per barrel range.

---

The Partnership believes that these prices are sufficient to sustain continued growth in crude oil production from the Western Canadian Sedimentary Basin, particularly from the Alberta Oil Sands. Due
to the lag in recovery of crude oil production in western Canada, it is anticipated that third quarter average daily deliveries on the Lakehead System will approximate the first six months of 2000,
followed by an increase in the fourth quarter. On an annual basis, this is expected to limit 2000 net income to approximately $70 million.

In
the long-term, the Partnership is well positioned to benefit from increases in crude oil supply through a combination of existing capacity and planned future expansion.
Canada has substantial reserves of non-conventional hydrocarbon resources consisting predominantly of oil sands deposits in the province of Alberta. Firms involved in the production of
heavy and synthetic crude oil from the oil sands region of western Canada have announced expansion programs in excess of Cdn $26 billion. If these projects are completed, they are projected to
provide substantial increases in the production of heavy and synthetic crude oil in western Canada in the next several years, which will support the long-term utilization of the Lakehead
System.

Enbridge Line 9

The Enbridge Pipelines System includes a section referred to as "Line 9" (previously known as the "Montreal Extension") which was reversed in 1999 to
flow from Montreal, Quebec to Sarnia, Ontario. The pipeline delivers off-shore crude oil imported into Quebec through facilities of Portland Pipe Line Corporation and Montreal Pipe Line
Limited to refineries in Ontario. Line 9 has an annual capacity of approximately 240,000 barrels per day and for the first six months of 2000, operated at approximately 195,000 barrels per day.
The ongoing utilization level of the line will be dependent upon global crude oil market dynamics.

The
reversal of Line 9 resulted in decreased deliveries of light crude oil from the Lakehead System to Ontario beginning in the second quarter of 1999. Displaced volumes
originating in western Canada are being diverted to other markets in the U.S. Midwest. During the first six months of 2000, deliveries to Clearbrook, Minnesota and Chicago, Illinois increased
compared to the same period last year, partially offsetting reductions in light crude deliveries to Ontario. Deliveries of U.S. domestic and foreign crude oil volumes between Chicago and
Ontario decreased 76,000 barrels per day for first half of 2000 as compared to the same period in 1999 due to the reversal of Line 9. The level of decline in deliveries from the Lakehead System
to Ontario will be dependent upon global crude oil market dynamics and the level of utilization of Line 9. For additional discussion on the impact of the Montreal Extension Reversal, see the
Partnership's 1999 Annual Report on Form 10-K.

Tariff Matters

On March 13, 2000, the Partnership filed a new tariff with the FERC, which took effect April 1, 2000. This new tariff reflects the annual
adjustment to the SEP II surcharge, including a true-up of the 1999 actual SEP II cost of service, along with an estimate for 2000. The tariff allows the Partnership to
recover the cost of service for SEP II facilities and earn a return on its SEP II equity investment, which varies with the utilization of SEP II capacity on the Enbridge Pipeline
System in western Canada. During 2000, the Partnership will earn a 7.5% return on its SEP II equity investment, the minimum provided in the SEP II Tariff Agreement.

Effective
July 1, 2000, in compliance with the indexed rate ceilings allowed by FERC, the Partnership increased its rates for transportation approximately 0.8%. The increase in
tariff rates is not expected to have a material impact on the Partnership.

Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This Statement requires that all derivatives be recognized at fair value in the balance sheet and all changes in fair value be recognized currently in earnings or
deferred as a component of other comprehensive income, depending on the intended use of the derivative, its resulting designation and its effectiveness. The Partnership plans to adopt this Statement
in 2001, as required. The Partnership has not determined the potential impact of implementing this Statement.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Partnership's financial instrument market risk is primarily impacted by changes in interest rates. The Partnership's exposure to movements in interest
rates is managed through its long-term debt ratio target, its allocation of fixed and floating rate debt, and the use of interest rate risk management agreements. Information about the
Partnership's financial instruments that are sensitive to changes in
interest rates has not changed from that presented in the Partnership's 1999 Annual Report on Form 10-K.

As
the Partnership does not own the crude oil and Natural Gas Liquids ("NGL") it transports, its cash flows are not significantly impacted by changes in commodity prices. However,
commodity prices have a significant impact on the underlying supply and demand for crude oil and NGL that the Partnership transports.

The
Partnership has minimal foreign exchange risk, and has entered into forward contracts to hedge its exposure to movements of future exchange rates.

The
Partnership does not currently hold or issue derivative instruments for trading or any other speculative purpose.

PART IIOTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

The Partnership is a defendant in various lawsuits and a party to various legal proceedings arising in the ordinary course of business. Some of these lawsuits
and proceedings are covered, in whole or in part, by insurance. The Partnership believes that the outcome of all these lawsuits and proceedings will not, individually or in the aggregate, have a
material adverse effect on the financial condition of the Partnership.

The
Partnership entered into a Stipulation and Order for Judgment with the State of Wisconsin on June 7, 2000, with regard to alleged violations of state pollution control
regulations. The Stipulation and Order requires the Partnership to pay forfeitures, assessments and expenses in the amount of $195,000 in exchange for a release from any further liability arising from
the claims alleged in a Complaint simultaneously filed by the State with the Stipulation and Order. The first three claims described in the Complaint relate to trench de-watering during
construction of a new line to Chicago, Illinois in the summer of 1998. The State alleged that the Partnership failed to comply with the terms of a discharge permit by failing to monitor all discharges
of water from construction trenches and, on certain occasions, by exceeding the effluent limitations. The fourth and unrelated claim described in the Complaint alleges that the Partnership failed to
immediately report a release of natural gas liquids from its Superior terminal in mid-January 1999.

For
information regarding other legal proceedings arising in 2000 or with regard to which material developments were reported during 2000, see Part II. Item 1., "Legal
Proceedings," in the Form 10-Q filed for the quarter ending March 31, 2000.
