Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Upon termination of service as a director, Deferred Share Units ("DSUs") recorded in the reporting person's account will be settled, at the reporting person's election, in common units of TC PipeLines, LP ("Common Units") at no additional cost on a 1 for 1 basis or in cash of equivalent value, less applicable withholdings.
(2) The DSUs are immediately fully vested and are redeemable only following Mr. Mirosh's termination of Board service.
(3) The DSUs were credited to the director's share unit account as distributions, effective on the payment date for distributions paid by TC PipeLines, LP on the Common Units. Pursuant to the Share Unit Plan for Non-Employee Directors (2007), the number of DSUs credited for distributions is calculated based on the distribution declared and paid on Common Units multiplied by the number of DSUs in the director's share account on the record date of such distribution, divided by the fair market value of Common Units on the payment date for such distribution.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
