arrangement will be exchanged, as part of the arrangement, for the

following completion of the arrangement and continue to be governed
by the terms of their indenture.

mailed to securityholders in late November for a special meeting of
the holders of common shares and debentures to take place in late

Measurements and Abbreviations 
All dollar amounts are referenced in Canadian dollars, except when
noted otherwise. Where amounts are expressed on a barrel of oil
equivalent ("BOE") basis, natural gas volumes have been converted to
oil equivalence at six thousand cubic feet per barrel and sulphur
volumes have been converted to oil equivalence at 0.6 long tons per
barrel. The term BOE may be misleading, particularly if used in
isolation. A BOE conversion ratio of six thousand cubic feet per
barrel is based on an energy equivalency conversion method primarily
applicable at the b
urner tip and does not represent a value
equivalency at the wellhead. References to "oil" in this discussion
include crude oil and natural gas liquids ("NGLs"). NGLs include
condensate, pentane, propane, butane and ethane. References to "gas"
in this discussion include natural gas and sulphur. 
This release does not constitute an offer to purchase or a
solicitation of an offer to sell any security, or a solicitation of
votes with respect to any security. Celtic securityholders are urged
