NewsRelease


             TC PipeLines, LP Declares Quarterly Cash Distribution;
                         Announces First Quarter Results

CALGARY, Alberta - April 21, 2003 - (Nasdaq: TCLP) - TC PipeLines, LP (the
Partnership) today announced that the board of directors of its general partner
has declared the Partnership's first quarter 2003 cash distribution in the
amount of US$0.525 per unit. The first quarter distribution will be paid on May
15, 2003 to unitholders of record as of April 30, 2003.

The Partnership also reported first quarter 2003 net income of US$11.9 million
or US$0.66 per unit, equaling net income reported for first quarter 2002.

The Partnership's first quarter 2003 cash generated from operations amounted to
US$13.5 million, a 10% increase compared to first quarter 2002 cash generated
from operations of US$12.3 million. The increase in cash flow reflects higher
cash distributions received from Northern Border Pipeline and Tuscarora.

FINANCIAL HIGHLIGHTS THREE MONTHS ENDED MARCH 31 (unaudited) (millions of U.S. dollars, except per unit amounts) - --------------------------------------------------------------------------------- -- ---------------------------- 2003 2002 ------------- -------------- Cash Distributions Declared Per Unit (1) $0.525 $0.50 Net Income 11.9 11.9 Per Unit (2) $0.66 $0.66 Cash Generated from Operations 13.5 12.3 Units Outstanding (millions) 17.5 17.5
(1) The Partnership's 2003 first quarter cash distribution will be paid on May 15, 2003 to unitholders of record as of April 30, 2003. (2) Net income per unit is computed by dividing net income, after deduction of the general partner's allocation, by the number of common and subordinated units outstanding. The general partner's allocation is computed based upon the general partner's 2% interest plus an amount equal to incentive distributions. -4- NET INCOME The Partnership reported first quarter 2003 net income of US$11.9 million or US$0.66 per unit, equaling net income reported for first quarter 2002. Equity income from Northern Border Pipeline amounted to US$11.0 million in first quarter 2003 compared to US$11.3 million for first quarter 2002. In first quarter 2003, Northern Border Pipeline incurred higher expenses related to electricity costs and taxes other than income compared to first quarter 2002. These decreases in Northern Border Pipeline's earnings were partially offset by lower interest expense, resulting from lower average interest rates, and higher revenues in first quarter 2003. Northern Border Pipeline's first quarter 2002 revenues were lower due to US$1.8 million of uncollected revenues (TC PipeLines' share is US$0.5 million) associated with the transportation capacity held by Enron North America (ENA), an Enron Corp. that filed for bankruptcy protection in December 2001. ENA no longer holds contracts for transportation capacity on the Northern Border pipeline system. Equity income from Tuscarora amounted to US$1.3 million in first quarter 2003 compared to US$1.1 million for first quarter 2002. The increase is primarily due to incremental revenues from Tuscarora's expansion facilities, which were placed into service on December 1, 2002, partially offset by increased operations and maintenance expense and depreciation expense related to the new facilities. The Partnership's first quarter 2003 general and administrative expenses of US$0.4 million were unchanged from first quarter 2002. Financial charges were less than US$0.1 million for first quarter 2003 compared to US$0.1 million first quarter 2002, primarily due to a decrease in the Partnership's average debt balance outstanding. CASH FLOW The Partnership reported first quarter 2003 cash generated from operations of US$13.5 million compared to US$12.3 million for first quarter 2002, reflecting higher cash distributions from both Northern Border Pipeline and Tuscarora. In first quarter 2003, the Partnership received a cash distribution from Northern Border Pipeline amounting to US$12.5 million compared to US$11.8 million for first quarter 2002. The increase is primarily due to lower interest expense incurred by Northern Border Pipeline. The Partnership also received a cash distribution from Tuscarora in first quarter 2003 amounting to US$1.5 million compared to US$1.0 million for first quarter 2002. The increase reflects Tuscarora's incremental cash inflows from new transportation contracts, including those related to Tuscarora's expansion facilities. During first quarter 2003, the Partnership used US$4.1 million of its cash from operations to fund a portion of Tuscarora's expansion, which was partially offset by a US$0.8 million return of capital from Tuscarora. The Partnership paid an aggregate US$9.6 million of cash distributions to unitholders and its general partner, the equivalent of US$0.525 per unit, in first quarter 2003, compared to US$9.0 million, the equivalent of US$0.50 per unit, in first quarter 2002. Also in first quarter 2003, the Partnership made a US$3.0 million principal repayment on its revolving credit facility, reducing its debt outstanding to US$8.5 million at March 31, 2003.
