FINANCIAL INFORMATION (CONTINUED) ITEM 1. FINANCIAL STATEMENTS (CONTINUED) TC PIPELINES, LP NOTES TO CONDENSED FINANCIAL STATEMENTS (unaudited) NOTE 1 BASIS OF PRESENTATION TC PipeLines, LP, and its subsidiary limited partnerships, TC PipeLines Intermediate Limited Partnership, and TC Tuscarora Intermediate Limited Partnership, all Delaware limited partnerships, are collectively referred to herein as TC PipeLines or the Partnership. The Partnership commenced operations on May 28, 1999. The financial statements have been prepared by management in accordance with United States generally accepted accounting principles. Amounts are stated in United States dollars. Since a determination of many assets, liabilities, revenues and expenses is dependent upon future events, the preparation of these financial statements requires the use of estimates and assumptions which have been made using careful judgment. In the opinion of management, these financial statements have been properly prepared within reasonable limits of materiality and include all adjustments (consisting primarily of normal recurring accruals) necessary to present fairly the results of operations for the three and six months ended June 30, 2001 and 2000, the financial position as at June 30, 2001 and December 31, 2000, and the cash flows for the six months ended June 30, 2001 and 2000. The results of operations for the three and six months ended June 30, 2001 and 2000 are not necessarily indicative of the results that may be expected for a full fiscal year. The interim financial statements should be read in conjunction with the Partnership's financial statements and notes included in TC PipeLines' Annual Report on Form 10-K for the year ended December 31, 2000. NOTE 2 INVESTMENT IN NORTHERN BORDER PIPELINE COMPANY The Partnership owns a 30% general partner interest in Northern Border Pipeline Company (Northern Border Pipeline), a partnership which owns a 1,214-mile interstate natural gas pipeline system extending from the Montana-Saskatchewan border near Port of Morgan, Montana, to a terminus near Manhattan, Illinois. Northern Border Pipeline is regulated by the Federal Energy Regulatory Commission (FERC). TC PipeLines uses the equity method of accounting for its investment in Northern Border Pipeline. TC PipeLines' equity income for each of the three and six months ended June 30, 2001 and 2000 represents 30% of the net income of Northern Border Pipeline for the same periods. The following sets out summarized financial information representing 100% of the operations of Northern Border Pipeline for the three and six months ended June 30, 2001 and 2000 and as at June 30, 2001 and December 31, 2000. <Table> <Caption> Three months ended Six months ended (unaudited) June 30 June 30 (millions of dollars) 2001 2000 2001 2000 - --------------------------------------------------------------------------------------------------------------------- NORTHERN BORDER PIPELINE INCOME STATEMENT Revenues 77.0 77.3 154.0 153.6 Costs and expenses (16.0) (18.5) (28.3) (35.3) Depreciation (14.3) (14.5) (28.7) (29.4) Financial charges (13.7) (16.4) (28.8) (32.7) Other income/(expense) (1.4) 1.5 (0.7) 1.9 ------------------------------------------------------------- ------------------------------------------------------------- Net income 31.6 29.4 67.5 58.1 ------------------------------------------------------------- ------------------------------------------------------------- </Table> 5 <Page> PART I.

Tuscarora owns a 229-mile interstate natural gas pipeline system extending from Oregon, where it interconnects with facilities of PG&E National Energy Group, Gas Transmission Northwest, to northern Nevada. Tuscarora is regulated by the FERC. The Partnership uses the equity method of accounting for its investment in Tuscarora. TC PipeLines' equity income for the three and six months ended June 30, 2001 represents 49% of the net income of Tuscarora for the same periods. The following sets out summarized financial information representing 100% of the operations of Tuscarora for the three and six months ended June 30, 2001 and as at June 30, 2001 and December 31, 2000. <Table> <Caption> (unaudited) Three months ended Six months ended (millions of dollars) June 30, 2001 June 30, 2001 - ----------------------------------------------------------------------------------------------- TUSCARORA INCOME STATEMENT Revenues 5.3 10.5 Costs and expenses (0.6) (1.2) Depreciation (1.2) (2.3) Financial charges (1.6) (3.1) Other income 0.1 0.2 ----------------------------------------- ----------------------------------------- Net income 2.0 4.1 ----------------------------------------- ----------------------------------------- </Table> 6 PART I.

Loans under the Revolving Credit Facility bear interest at a floating rate. The Revolving Credit Facility matures on August 31, 2003. Amounts borrowed may be repaid in part or in full prior to that time without penalty. The Revolving Credit Facility may be used to finance capital expenditures and for other general purposes. On September 1, 2000, the Partnership borrowed $24.5 million under the Revolving Credit Facility to fund a portion of the purchase price of the 49% general partner interest in Tuscarora. At June 30, 2001, the Partnership had borrowings of $21.5 million outstanding under the Revolving Credit Facility at an interest rate of 4.935%. The fair value of the Revolving Credit Facility approximates its carrying value. On May 28, 2001, the Partnership renewed its $40 million unsecured two-year revolving credit facility (TransCanada Credit Facility) with TransCanada PipeLine USA Ltd., an affiliate of the general partner. The TransCanada Credit Facility bears interest at London Interbank Offered Rate plus 1.25%. The purpose of the TransCanada Credit Facility is to provide borrowings to fund capital expenditures, to fund capital contributions to Northern Border Pipeline, Tuscarora, and any other entity in which it directly or indirectly acquires an interest, to fund working capital and for other general business purposes, including temporary funding of cash distributions to partners, if necessary. At June 30, 2001, the Partnership had no amount outstanding under the TransCanada Credit Facility. NOTE 5 NET INCOME PER UNIT Net income per unit is computed by dividing net income, after deduction of the general partner's allocation, by the weighted average number of common and subordinated units outstanding. The general partner's allocation is equal to an amount based upon the general partner's 2% interest, adjusted to reflect an amount equal to incentive distributions. Net income per unit was determined as follows: <Table> <Caption> Three months ended June 30 Six months ended June 30 (thousands of dollars, except per unit amounts) 2001 2000 2001 2000 - ----------------------------------------------------------------------------------------------------------------------- Net income 9,793 8,533 20,756 16,877 -------------------------------------------------------- Net income allocated to general partner (197) (171) (416) (338) Adjustment to reflect incentive distribution income (144) - (230) - allocation -------------------------------------------------------- (341) (171) (646) (338) -------------------------------------------------------- Net income allocable to units 9,452 8,362 20,110 16,539 Weighted average units outstanding (thousands) 17,500 17,500 17,500 17,500 -------------------------------------------------------- Net income per unit $0.54 $0.48 $1.15 $0.95 -------------------------------------------------------- -------------------------------------------------------- </Table> NOTE 6 DISTRIBUTIONS On July 18, 2001 the Partnership declared a cash distribution of $0.50 per unit for the quarter ended June 30, 2001. The distribution is payable on August 14, 2001 to unitholders of record at July 31, 2001. 7 <Page> PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS TC PIPELINES, LP RESULTS OF OPERATIONS OF TC PIPELINES, LP TC PipeLines, LP (TC PipeLines or the Partnership) was formed by TransCanada PipeLines Limited (TransCanada) to acquire, own and participate in the management of United States based pipeline assets. On May 28, 1999, the Partnership acquired a 30% general partner interest in Northern Border Pipeline Company (Northern Border Pipeline), previously held by affiliates of its general partner, TC PipeLines GP, Inc. Northern Border Pipeline owns a 1,214-mile interstate pipeline system that transports natural gas from the Montana-Saskatchewan border to markets in the midwestern United States. On September 1, 2000, TC PipeLines, through its wholly owned subsidiary, TC Tuscarora Intermediate Limited Partnership, acquired a 49% general partner interest in Tuscarora Gas Transmission Company (Tuscarora) for a cash purchase price of $28 million. The purchase price was funded with debt (see Liquidity and Capital Resources of TC PipeLines, LP - General) and cash on hand. Tuscarora owns a 229-mile interstate pipeline system that transports natural gas from Oregon, where it interconnects with facilities of PG&E National Energy Group, Gas Transmission Northwest, to northern Nevada. TC PipeLines accounts for its interests in Northern Border Pipeline and Tuscarora using the equity method of accounting. PROPOSED TUSCARORA EXPANSION On April 12, 2001, the Partnership announced that Tuscarora filed an application with the Federal Energy Regulatory Commission (FERC) to expand its pipeline system to meet new service requests. If approved, the expansion would begin commercial operations in late 2002. The proposed expansion will consist of three compressor stations and a 14-mile pipeline extension from the current terminus of the Tuscarora pipeline system near Reno, Nevada to Wadsworth, Nevada. The capital cost of the project is estimated to be approximately $60 million. The Tuscarora expansion is expected to increase capacity on the Tuscarora pipeline system from approximately 124 million cubic feet per day to approximately 220 million cubic feet per day and is supported by long-term firm transportation contracts ranging from ten to fifteen years. Sierra Pacific Power Company, a subsidiary of Sierra Pacific Resources Company, which holds a 50% general partner interest in Tuscarora, has contracted for approximately 11 million cubic feet per day of the increased capacity. SECOND QUARTER 2001 COMPARED WITH SECOND QUARTER 2000 Equity income from the Partnership's investment in Northern Border Pipeline increased $0.7 million or 8%, to $9.5 million for the second quarter of 2001, compared to equity income of $8.8 million for the same period in 2000. This increase is primarily attributable to Northern Border Pipeline incurring lower operations and maintenance expense and lower interest expense due to lower interest rates and lower average debt balances. These increases are partially offset by Northern Border Pipeline's write-off of accounts receivable outstanding from a telecommunications company that has declared bankruptcy. The telecommunications company had been purchasing excess capacity on the microwave communications system of Northern Border Pipeline. For the second quarter of 2001, the Partnership recorded equity income of $0.9 million from its investment in Tuscarora. The Partnership acquired its 49% interest in Tuscarora on September 1, 2000. The Partnership incurred general and administrative expenses of $0.3 million for each of the second quarter of 2001 and the second quarter of 2000. The Partnership incurred financial charges of $0.3 million for the second quarter of 2001, which are comprised primarily of interest expense under the Partnership's Revolving Credit Facility (see Liquidity and Capital Resources of TC PipeLines, LP - General). The Partnership entered into the Revolving Credit Facility on August 22, 2000 and borrowed $24.5 million thereunder on September 1, 2000 to fund a portion of the purchase price of its 49% general partner interest in Tuscarora. SIX MONTHS ENDED JUNE 30, 2001 COMPARED WITH SIX MONTHS ENDED JUNE 30, 2000 Equity income from the Partnership's investment in Northern Border Pipeline increased $2.8 million or 16%, to $20.3 million for the first six months of 2001, compared to equity income of $17.5 million for the same period in 2000. This increase is primarily attributable to Northern Border Pipeline incurring lower operations and maintenance expense and 8 <Page> PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) TC PIPELINES, LP lower interest expense due to lower interest rates and lower average debt balances, in addition to adjustments made by Northern Border Pipeline to previous estimates of ad valorem taxes. These increases are partially offset by Northern Border Pipeline's write-off of accounts receivable outstanding from a telecommunications company that has declared bankruptcy. For the first half of 2001, the Partnership recorded equity income of $1.8 million from its investment in Tuscarora. The Partnership acquired its 49% interest in Tuscarora on September 1, 2000. The Partnership incurred general and administrative expenses of $0.7 million for the six months ended June 30, 2001 compared to $0.6 million for the same period in 2000. The Partnership incurred financial charges of $0.6 million for the first six months of 2001, which are comprised primarily of interest expense under the Partnership's Revolving Credit Facility (see Liquidity and Capital Resources of TC PipeLines, LP - General). The Partnership entered into the Revolving Credit Facility on August 22, 2000 and borrowed $24.5 million thereunder on September 1, 2000 to fund a portion of the purchase price of its 49% general partner interest in Tuscarora. LIQUIDITY AND CAPITAL RESOURCES OF TC PIPELINES, LP CASH DISTRIBUTION POLICY OF TC PIPELINES, LP During the subordination period, which generally cannot end before June 30, 2004, the Partnership will make distributions of available cash as defined in the partnership agreement in the following manner: o First, 98% to the common units, pro rata, and 2% to the general partner, until there has been distributed for each outstanding common unit an amount equal to the minimum quarterly distribution for that quarter; o Second, 98% to the common units, pro rata, and 2% to the general partner, until there has been distributed for each outstanding common unit an amount equal to any arrearages in payment of the minimum quarterly distribution on the common units for that quarter and for any prior quarters during the subordination period; o Third, 98% to the subordinated units, pro rata, and 2% to the general partner, until there has been distributed for each outstanding subordinated unit an amount equal to the minimum quarterly distribution for that quarter; and o Thereafter, in a manner whereby the general partner has rights (referred to as incentive distribution rights) to receive increasing percentages of excess quarterly distributions over specified distribution thresholds. GENERAL On July 18, 2001, the board of directors of the general partner declared the Partnership's 2001 second quarter cash distribution in the amount of $0.50 per unit, representing a $0.025 per unit increase from the previous quarterly distribution level of $0.475 per unit. This distribution will be paid on August 14, 2001 to unitholders of record as of July 31, 2001. The second quarter cash distribution totaling 9 <Page> PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) TC PIPELINES, LP $9.1 million will be paid in the following manner: $7.4 million to common unitholders, $1.4 million to the general partner as holder of the subordinated units, and $0.3 million to the general partner, as holder of incentive distribution rights and in respect of its 2% general partner interest. On August 22, 2000, the Partnership entered into an unsecured three-year credit facility (Revolving Credit Facility) with Bank One, NA, as agent, under which the Partnership may borrow up to an aggregate principal amount of $30 million. Loans under the Revolving Credit Facility may bear interest, at the option of the Partnership, at a one-, two-, three-, or six-month London Interbank Offered Rate (LIBOR) plus 0.875%, or at a floating rate based on the higher of the federal funds effective rate plus 0.50% or the prime rate. The Revolving Credit Facility matures on August 31, 2003. Amounts borrowed may be repaid in part or in full prior to that time without penalty. The Revolving Credit Facility may be used to finance capital expenditures and for other general purposes. On September 1, 2000, the Partnership borrowed $24.5 million under the Revolving Credit Facility to fund a portion of the purchase price of the 49% general partner interest in Tuscarora. At June 30, 2001, the Partnership had borrowings of $21.5 million outstanding under the Revolving Credit Facility at an interest rate of 4.935%. On May 28, 2001, the Partnership renewed its $40 million unsecured two-year revolving credit facility (TransCanada Credit Facility) with TransCanada PipeLine USA Ltd., an affiliate of the general partner. The TransCanada Credit Facility bears interest at LIBOR plus 1.25%. The purpose of the TransCanada Credit Facility is to provide borrowings to fund capital expenditures, to fund capital contributions to Northern Border Pipeline, Tuscarora, and any other entity in which it directly or indirectly acquires an interest, to fund working capital and for other general business purposes, including temporary funding of cash distributions to partners, if necessary. At June 30, 2001, the Partnership had no amount outstanding under the TransCanada Credit Facility. CASH FLOWS FROM OPERATING ACTIVITIES Cash flows provided by operating activities increased by 9% to $20.2 million for the six months ended June 30, 2001 from $18.6 million for the same period last year. For the six months ended June 30, 2001, the Partnership received cash distributions in aggregate of $21.8 million from its equity investments in Northern Border Pipeline and Tuscarora, compared to $19.3 million from its equity investment in Northern Border Pipeline during the same period of 2000, representing an increase of 13%. CASH FLOWS FROM FINANCING ACTIVITIES For the six months ended June 30, 2001, the Partnership paid $17.1 million in distributions: $14.0 million to common unitholders, $2.7 million to the general partner as holder of the subordinated units, and $0.4 million to the general partner, as holder of incentive distribution rights and in respect of its 2% general partner interest. This compares to cash distributions of $16.1 million which were paid by the Partnership in the six months ended June 30, 2000. CAPITAL REQUIREMENTS To the extent TC PipeLines has any capital requirements with respect to its investments in Northern Border Pipeline and Tuscarora or makes acquisitions 10 <Page> PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) TC PIPELINES, LP in 2001, TC PipeLines expects to finance these requirements with debt and/or equity. Since the interests in Northern Border Pipeline and Tuscarora are currently the Partnership's only significant sources of income, the Partnership's results of operations are influenced by and reflect the same factors that influence the financial results of Northern Border Pipeline and Tuscarora. RESULTS OF OPERATIONS OF NORTHERN BORDER PIPELINE COMPANY The following sets out summarized financial information for Northern Border Pipeline for the three months ended June 30, 2001 and 2000, for the six months ended June, 2001 and 2000 and as at June 30, 2001 and December 31, 2000. Amounts discussed represent 100% of the operations of Northern Border Pipeline, in which the Partnership has held a 30% interest since May 28, 1999. <Table> <Caption> (unaudited) Three months ended June 30 Six months ended June 30 (millions of dollars) 2001 2000 2001 2000 - -------------------------------------------------------------------------------------------------------------------- NORTHERN BORDER PIPELINE INCOME STATEMENT Revenues 77.0 77.3 154.0 153.6 Costs and expenses (16.0) (18.5) (28.3) (35.3) Depreciation (14.3) (14.5) (28.7) (29.4) Financial charges (13.7) (16.4) (28.8) (32.7) Other income/(expense) (1.4) 1.5 (0.7) 1.9 --------------------------------------------------------------- --------------------------------------------------------------- Net income 31.6 29.4 67.5 58.1 --------------------------------------------------------------- --------------------------------------------------------------- </Table> 11 PART I.

It transports gas under a FERC regulated tariff. Northern Border Pipeline had used a cost of service form of tariff since its inception but agreed to convert to a stated rate form of tariff as part of the settlement of its rate case discussed below. Under the cost of service tariff, Northern Border Pipeline was provided 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 was generally allowed to collect from its shippers a return on regulated rate base as well as recover that rate base through depreciation and amortization. Billings for the firm transportation agreements were based on contracted volumes to determine the allocable share of the cost of service and were not dependent upon the percentage of available capacity actually used. Northern Border Pipeline filed a rate proceeding with the FERC in May 1999 for, among other things, a redetermination of its allowed equity rate of return. In September 2000, Northern Border Pipeline filed a stipulation and agreement with the FERC that documented the proposed settlement of its pending rate case. The settlement was approved by the FERC in December 2000. Under the approved settlement, effective December 1, 1999, shippers began paying stated transportation rates based on a straight fixed variable rate design. Under the straight fixed variable rate design, approximately 98% of the agreed upon revenue level is attributed to demand charges, based upon contracted firm capacity, and the remaining 2% is attributed to commodity charges, based on the volumes of gas actually transported on the system. 12 <Page> PART I.

Contracts for approximately 44% of the capacity will expire between mid-September 2003 and the end of October 2005. SECOND QUARTER 2001 COMPARED WITH SECOND QUARTER 2000 Revenues decreased $0.3 million for the second quarter of 2001, as compared to the same period in 2000. Northern Border Pipeline's revenues for 2001 reflect the rate case settlement discussed above. Revenues for 2000 were determined under Northern Border Pipeline's cost of service tariff.

Financial charges decreased $2.7 million (16%) for the second quarter of 2001, as compared to the same period in 2000, due primarily to a decrease in Northern Border Pipelines average interest rates between 2000 and 2001 as well as a decrease in average debt outstanding. Other income/(expense) decreased $2.8 million for the second quarter of 2001, as compared to the same period in 2000. Other income/(expense) for the second quarter of 2001 includes a charge of approximately $1.7 million for an uncollectible receivable from a telecommunications company that had purchased excess capacity on Northern Border Pipeline's communication system. In the second quarter of 2000, Northern Border Pipeline had recorded approximately $1.2 million of income from purchase of excess capacity by the telecommunications company.

In the first half of 2000, Northern Border Pipeline had recorded approximately $1.2 million of income from the purchase of excess capacity by the telecommunications company. LIQUIDITY AND CAPITAL RESOURCES OF NORTHERN BORDER PIPELINE COMPANY GENERAL Northern Border Pipeline had previously entered into a 1997 credit agreement (Pipeline Credit Agreement) with certain financial institutions, which is comprised of a $200 million five-year revolving credit facility and a $389 million term loan, both maturing in June 2002. At June 30, 2001, $85 million was outstanding under the five-year revolving credit facility. Northern Border Pipeline intends to refinance a portion of the Pipeline Credit Agreement in the third quarter of 2001 and refinance any remaining amounts outstanding by the first quarter of 2002. At June 30, 2001, Northern Border Pipeline also had outstanding $184 million of senior notes issued in a $250 million private placement under a July 1992 note purchase agreement. The note purchase agreement provides for four series of notes, Series A through D, maturing between August 2000 and August 2003. The Series A Notes with a principal amount of $66 million were repaid in August 2000. The Series B Notes with a principal amount of $41 million mature in August 2001. Northern Border Pipeline anticipates borrowing on the Pipeline Credit Agreement to repay the Series B Notes. In March 2001, Northern Border Pipeline entered into forward starting interest rate swaps with notional amounts totaling $200 million related to a planned issuance of 10-year and 30-year fixed rate debt. The swap instruments may be settled any time prior to their expiration date on October 1, 2001. The proceeds from the issuance of the fixed rate debt will be used to repay outstanding indebtedness. Short-term liquidity needs will be met by internal sources and through the revolving credit facility discussed above. Long-term capital needs may be met through the ability to issue long-term indebtedness. CASH FLOWS FROM OPERATING ACTIVITIES Cash flows provided by operating activities decreased $7.4 million to $89.9 million for the first half of 2001, as compared to the same period in 2000. During 2001, Northern Border Pipeline realized net cash outflows of approximately $4.7 million related to its rate case. During the first quarter of 2001, Northern Border Pipeline made refunds to its shippers totaling $6.8 million, which included $2.1 million collected in the first quarter of 2001 with the remainder collected previously. CASH FLOWS FROM INVESTING ACTIVITIES Capital expenditures of $15.6 million for the first half of 2001 included $12.4 million for Project 2000, Northern Border Pipeline's 34-mile extension and expansion into Indiana. For the comparable period in 2000, capital expenditures were $3.8 million and included $2.3 million for Project 2000. The remaining capital expenditures for 2001 and 2000 were primarily related to renewals and replacements of existing facilities. Total capital expenditures for 2001 are estimated to be $76 million, including $61 million for Project 2000. The remaining capital expenditures planned for 2001 are for renewals and replacements of existing facilities. Northern Border Pipeline currently anticipates funding its 2001 capital expenditures primarily by debt borrowings and using internal sources. CASH FLOWS FROM FINANCING ACTIVITIES Cash flows used in financing activities increased $12.7 million to $87.3 million for the first half of 2001 as compared to same period in 2000. For the first half of 2001, Northern Border Pipeline recognized a decrease in bank overdraft of $22.4 million. At December 31, 2000, Northern Border Pipeline reflected the bank overdraft primarily due to rate case refund checks outstanding. Distributions to partners increased $5.5 million to $69.9 million for the first half of 2001, as compared to the same period in 2000, primarily due to an increase in net income. During the first half of 2001, Northern Border Pipeline had net borrowings under the Pipeline Credit Agreement of $5.0 million as compared to net repayments in 2000 of $10.0 million. 14 <Page> PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) TC PIPELINES, LP RESULTS OF OPERATIONS OF TUSCARORA GAS TRANSMISSION COMPANY The following sets out summarized financial information for Tuscarora for the three and six months ended June 30, 2001 and as at June 30, 2001 and December 31, 2000. Amounts discussed represent 100% of the operations of Tuscarora, in which the Partnership has held a 49% interest since September 1, 2000. <Table> <Caption> (unaudited) Three months ended Six months ended (millions of dollars) June 30, 2001 June 30, 2001 - ------------------------------------------------------------------------------------------------ TUSCARORA INCOME STATEMENT Revenues 5.3 10.5 Costs and expenses (0.6) (1.2) Depreciation (1.2) (2.3) Financial charges (1.6) (3.1) Other income 0.1 0.2 ------------------------------------------- ------------------------------------------- Net income 2.0 4.1 ------------------------------------------- ------------------------------------------- </Table> <Table> <Caption> June 30, 2001 (millions of dollars) (unaudited) December 31, 2000 - ------------------------------------------------------------------------------------------------ TUSCARORA BALANCE SHEET ASSETS Cash and cash equivalents 4.5 7.1 Other current assets 2.7 3.2 Plant, property and equipment, net 116.5 115.7 Other assets 2.2 2.5 ------------------------------------------- 125.9 128.5 ------------------------------------------- ------------------------------------------- LIABILITIES AND PARTNERS' CAPITAL Current liabilities 5.4 8.9 Reserves and deferred credits 14.1 12.0 Long-term debt 82.1 84.2 Partners' capital 24.3 23.4 ------------------------------------------- 125.9 128.5 ------------------------------------------- ------------------------------------------- </Table> SECOND QUARTER 2001 COMPARED WITH SECOND QUARTER 2000 Revenues generated by Tuscarora were $5.3 million for the second quarter of 2001 compared to $4.8 million for the second quarter of 2000. The $0.5 million (10%) increase is due to additional contracted capacity on the Hungry Valley lateral, a 14-mile, 16-inch pipeline extension that is Tuscarora's second connection into Reno, Nevada. The Hungry Valley lateral was completed in January 2001. Costs and expenses, depreciation and financial charges incurred and other income earned by Tuscarora in the second quarter of 2001 were consistent with the same period last year. SIX MONTHS ENDED JUNE 30, 2001 COMPARED WITH SIX MONTHS ENDED JUNE 30, 2000 Revenues generated by Tuscarora were $10.5 million for the second quarter of 2001 compared to $9.6 million for the same period last year. The $0.9 million (9%) increase is due to additional contracted capacity on the Hungry Valley lateral. Costs and expenses, depreciation and financial charges incurred and other income earned by Tuscarora in the first half of 2001 were consistent with the same period last year. 15 PART I. FINANCIAL INFORMATION (CONTINUED) ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONCLUDED) TC PIPELINES, LP LIQUIDITY AND CAPITAL RESOURCES OF TUSCARORA GAS TRANSMISSION COMPANY GENERAL In September 2000, Tuscarora adopted a cash distribution policy that became effective January 1, 2001. Under the terms of the cash distribution policy, Tuscarora makes quarterly cash distributions to its general partners in accordance with their respective general partner interests. Cash distributions are generally computed as the sum of Tuscarora's net income before income taxes and depreciation and amortization, less amounts required for debt repayments, net of refinancings, maintenance capital expenditures, certain non-cash items, and any cash reserves deemed necessary by the management committee of Tuscarora. Cash distributions will be computed at the end of each calendar quarter and the distribution will be made on or before the last day of the month following the quarter end. CASH FLOWS FROM OPERATING ACTIVITIES Cash flows provided by operating activities decreased to $3.9 million for the first six months of 2001 compared to $5.6 million for the same period in 2000 due to changes in working capital. CASH FLOWS FROM INVESTING ACTIVITIES Net cash used in investing activities increased to $3.1 million for the six month period ended June 30, 2001 compared to $0.7 million for the same period last year. This increase is due to construction of the Hungry Valley lateral that went into service in January 2001. CASH FLOWS FROM FINANCING ACTIVITIES During the first six months of 2001, Tuscarora recorded cash flow used in financing activities of $3.5 million compared to $4.0 million for the same period in 2000. Tuscarora paid a cash distribution of $1.7 million during the first six months of 2001 compared to $2.2 million for the same period in 2000. NEW ACCOUNTING PRONOUNCEMENT TC PipeLines has implemented Statement of Financial Accounting Standards (SFAS) No. 133 "Accounting for Derivative Instruments and Hedging Activities" on January 1, 2001. TC PipeLines does not hold any derivative instruments and does not participate in hedging activities. Northern Border Pipeline's adoption of SFAS No. 133 on January 1, 2001 has not had a material impact on TC PipeLines' investment in or equity income from Northern Border Pipeline. As a result, SFAS No. 133 does not have a material impact on TC PipeLines' financial position or results of operations. In July 2001, the Financial Accounting Standards Board issued SFAS No. 143, "Accounting for Asset Retirement Obligations". SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after June 15, 2002, with earlier application encouraged. TC PipeLines does not currently have long-lived assets recorded on its balance sheet. TC PipeLines is in the process of evaluating the application of this pronouncement on its investments in Northern Border Pipeline and Tuscarora.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK TC PIPELINES, LP TC PipeLines, LP's interest rate exposure results from its Revolving Credit Facility which is subject to variability in LIBOR interest rates. Since December 31, 2000, there has not been any material change to TC PipeLines' interest rate exposure. The Partnership's market risk sensitivity is also influenced by and reflects the same factors that influence Northern Border Pipeline. Northern Border Pipeline's interest rate exposure results from variable rate borrowings from commercial banks. To mitigate potential fluctuations in interest rates, Northern Border Pipeline attempts to maintain a significant portion of its debt portfolio in fixed rate debt. Northern Border Pipeline also uses interest rate swap agreements to increase the portion of its fixed rate debt. Since December 31, 2000, there has not been any material change to Northern Border Pipeline's interest rate exposure. 17 PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS TC PIPELINES, LP On July 31, 2001, the Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation filed a lawsuit in the Tribal Court against Northern Border Pipeline Company to collect more than $3 million in back taxes, together with interest and penalties. The lawsuit relates to a utilities tax on certain of Northern Border Pipeline's properties within the Fort Peck Reservation. Based on recent decisions by the Federal courts and other defenses, Northern Border Pipeline believes that the Tribes do not have the authority to impose the tax. In any event, TC PipeLines believes that the lawsuit will not have a material adverse impact on the Partnership. 18 PART II. OTHER INFORMATION (CONCLUDED) ITEM 6.
