system, as that price is provided in the publication entitled, "Inside
F.E.R.C.'s Gas Market Report" in the table entitled, "Prices of Spot Gas
Delivered to Pipelines.....(per MMBtu dry), under the "Northwest Pipeline Corp"
entry multiplied by 35%; and

(iii)the "AECO "C" & N.I.T. One-Month Spot" price as published by the "Canadian
Gas Price Reporter" in the table entitled, "Canadian Natural Gas Supply Prices"
under the column entitled "Avg" in U.S$/MMBtu multiplied by 39%.

b.The reference publication issue to determine the Gas Commodity Price for a
month shall be the first issue which is published after the first day of the
month.

c.The percentage of the Index Price shall be as follows:
November 1, 2001 March 31, 2002 — 90%
April 1, 2002 — October 31, 2002 — 85%

2)Price Conversion: i)November 1, 2001 — October 31, 2004*
Price conversion transacted on April 3 and 4th, 2001 for the entire 27,037
MMBtu/Day
Price = U.S$4.66 per MMBtu

*The application as per 1)c. will equate to the following:
For the period November 1, 2001 to March 2, 2002 = U.S$[*]per MMBtu
For the period April 1, 2002 to October 31, 2002 = U.S$[*]per MMBtu

ii)The Parties acknowledge and agree that the fixed price conversion hedge set
out above is and will remain in full force and effect, even if the Index Price

in Section 1)c. are renegotiated.

iii)If:

consistent with the Index Price changes or amendments. Notwithstanding such
efforts, Buyer will remain liable for any losses or gains resulting from Buyer
being overhedged or underhedged due to the Index Price changes or amendments.

iv)If price renegotiations are commenced between Buyer and Seller and between
Seller and PanAlberta in accordance with the August 17, 1994 Agreement then
Seller shall use commercially reasonable efforts to ensure any such Index Price
changes or amendments do not result in Buyer being underhedged or overhedged in
accordance with the above.

v)In the event:

A)Seller's credit rating as determined by Standard and Poors falls below "BBB";
or

B)the aggregate mark to market valuation for all forms of energy related
agreements, arrangements and transactions between Buyer and Seller (as such
