"EnCana Holdings  Finance",  "we", "us" and "our" mean EnCana Holdings Finance

     In this  prospectus and in any prospectus  supplement,  unless  otherwise

States  dollars and all  references  to "C$" are to Canadian  dollars.  Unless

     We may, from time to time,  sell any  combination of the debt  securities
described  in this  prospectus  in one or more  offerings  up to an  aggregate
principal  amount of  US$2,000,000,000.  This  prospectus  provides you with a

                      WHERE YOU CAN FIND MORE INFORMATION

     INFORMATION  HAS BEEN  INCORPORATED  BY REFERENCE IN THIS PROSPECTUS FROM
DOCUMENTS FILED WITH SECURITIES  COMMISSIONS OR SIMILAR AUTHORITIES IN CANADA.
Copies of the  documents  incorporated  herein by reference may be obtained on
request  without  charge from the Corporate  Secretary of EnCana  Corporation,
1800, 855 - 2nd Street S.W., P.O. Box 2850, Calgary,  Alberta T2P 2S5, Canada,
telephone:  (403)  645-2000.  These  documents are also available  through the
internet  via the  System  for  Electronic  Document  Analysis  and  Retrieval
(SEDAR), which can be accessed at www.sedar.com.

     The Guarantor  files with the securities  commission or authority in each
of the provinces  and  territories  of Canada  annual and  quarterly  reports,
material change reports and other information. The Guarantor is subject to the
informational  requirements  of the United States  Securities  Exchange Act of
1934, as amended (the  "Exchange  Act") and, in  accordance  with the Exchange
Act, it also files reports with and furnishes  other  information  to the SEC.
Under the multijurisdictional  disclosure system adopted by the United States,
these reports and other information  (including financial  information) may be
prepared in  accordance  with the  disclosure  requirements  of Canada,  which
differ from those in the United  States.  You may read any  document we or the
Guarantor  furnish to the SEC at the SEC's public reference room at Room 1580,
100 F Street, N.E., Washington,  D.C. 20549. You may also obtain copies of the
same  documents  from the  public  reference  room of the SEC at 100 F Street,
N.E.,  Washington  D.C.  20549  by  paying  a  fee.  Please  call  the  SEC at
1-800-SEC-0330  or contact them at www.sec.gov for further  information on the

                                      2


public reference  rooms. The Guarantor's  filings since November 2002 are also
electronically  available  from the SEC's  Electronic  Document  Gathering and
Retrieval  System,  which is commonly known by the acronym EDGAR and which may
be accessed at  www.sec.gov,  as well as from  commercial  document  retrieval
services.

     We do not intend to file with Canadian securities regulatory  authorities
separate  continuous  disclosure  information  apart  from,  where  there is a
material change in our business,  operations or capital that is not a material
change in respect of the Guarantor,  a material  change  report.  We have been
granted  exemptions  from all  remaining  continuous  disclosure  requirements
contained within the securities legislation of each of the provinces of Canada
(the  "Decisions").  The Decisions  provide,  in part, that we are entitled to
file, in lieu of such continuous  disclosure  filings,  certain filings of the
Guarantor made with the Canadian securities regulatory authorities.

     Under  applicable  securities  laws in Canada and the United States,  the
Canadian  securities  commissions  and  the SEC  allow  us to  incorporate  by
reference certain  information that the Guarantor files with them, which means
that we can disclose  important  information  to you by referring you to those
documents.  Information that is incorporated by reference is an important part
of this  prospectus.  We incorporate by reference the documents  listed below,
which were filed  with the  Canadian  securities  commissions  under  Canadian
securities legislation:

     (c)   the Guarantor's  Management's  Discussion and Analysis for the year

     ANY  STATEMENT  CONTAINED  IN THIS  PROSPECTUS  OR IN A DOCUMENT (OR PART
THEREOF) INCORPORATED BY REFERENCE, OR DEEMED TO BE INCORPORATED BY REFERENCE,
IN THIS PROSPECTUS SHALL BE DEEMED TO BE MODIFIED OR SUPERSEDED,  FOR PURPOSES
OF THIS PROSPECTUS, TO THE EXTENT THAT A STATEMENT CONTAINED IN THE PROSPECTUS
OR IN ANY  SUBSEQUENTLY  FILED  DOCUMENT (OR PART THEREOF) THAT ALSO IS, OR IS
DEEMED  TO BE,  INCORPORATED  BY  REFERENCE  IN THIS  PROSPECTUS  MODIFIES  OR
REPLACES SUCH STATEMENT.  ANY STATEMENT SO MODIFIED OR SUPERSEDED SHALL NOT BE
DEEMED,  EXCEPT AS SO  MODIFIED  OR  SUPERSEDED,  TO  CONSTITUTE  PART OF THIS
PROSPECTUS.  THE MODIFYING OR SUPERSEDING STATEMENT NEED NOT STATE THAT IT HAS

FORTH IN THE DOCUMENT WHICH IT MODIFIES OR SUPERSEDES.

     Updated interest coverage ratios will be filed quarterly by the Guarantor
with the  applicable  securities  regulatory  authorities,  including the SEC,
either as  prospectus  supplements  or exhibits to the  Guarantor's  unaudited

                                      3

deemed no longer to be  incorporated  into this  prospectus  for  purposes  of
future offers and sales of debt securities under this prospectus. Upon interim
consolidated financial statements and the accompanying management's discussion
and  analysis  being filed by the  Guarantor  with the  applicable  securities

                          FORWARD-LOOKING STATEMENTS

     Certain  statements   included  in  this  prospectus  and  the  documents

statements,  as there  can be no  assurance  that  the  plans,  intentions  or
expectations   upon  which  they  are  based  will  occur.  By  their  nature,
forward-looking  statements  involve numerous  assumptions,  known and unknown
risks and  uncertainties,  both general and specific,  that  contribute to the
possibility  that the  predictions,  forecasts,  projections  and other things
contemplated by the  forward-looking  statements  will not occur.  Although we
believe that the expectations  represented by such forward-looking  statements
are reasonable, there can be no assurance that such expectations will prove to
be correct.  Some of the risks and other  factors which could cause results to
differ  materially  from those  expressed  in the  forward-looking  statements
contained  in this  prospectus  and the  documents  incorporated  by reference
herein  include,  but  are  not  limited  to:  volatility  of and  assumptions
regarding oil and natural gas prices,  assumptions based upon EnCana's current
guidance,  fluctuations  in currency and interest  rates,  product  supply and
demand,  market  competition,  risks  inherent in EnCana's  North American and
foreign  oil  and  natural  gas  and  midstream  operations,   risks  of  war,
hostilities,  civil insurrection and instability  affecting countries in which
EnCana and its subsidiaries  operate and terrorist threats,  risks inherent in
EnCana's and its subsidiaries'  marketing  operations,  including credit risk,
imprecision of reserves  estimates and estimates of recoverable  quantities of
oil,  natural  gas and  liquids  from  resource  plays and other  sources  not
currently  classified  as  proved  reserves,  EnCana's  and its  subsidiaries'
ability to replace and expand oil and natural gas reserves,  risks  associated
with  technology,  EnCana's  ability  to  generate  sufficient  cash flow from
operations  to meet its current and future  obligations,  EnCana's  ability to
access  external  sources of debt and equity  capital,  general  economic  and
business  conditions,  EnCana's  ability  to enter into or renew  leases,  the
timing and costs of gas  storage  facility,  well and  pipeline  construction,
EnCana's  ability  to make  capital  investments  and the  amounts  of capital
investments,  imprecision  in  estimating  the  timing,  costs  and  levels of
production and drilling, the results of exploration, development and drilling,
imprecision  in  estimates  of future  production  capacity,  EnCana's and its
subsidiaries' ability to secure adequate product  transportation,  uncertainty
in the amounts of timing of royalty  payments,  imprecision  in  estimates  of

regulatory  approvals and such other risks and  uncertainties  described  from

Box 997, Halifax, Nova Scotia, B3J 2X2.

     We are part of a group of EnCana's  subsidiaries and  partnerships  which
carry on  substantially  all of EnCana's  operations in the United States (the
"U.S.  Group").  We have been established for the purpose of raising financing
for the U.S. Group. We have no subsidiaries and, except as aforesaid,  have no
active business.

     Unless  otherwise  indicated  in  the  applicable  prospectus  supplement
relating to a series of debt  securities,  we will advance the net proceeds we
receive from the sale of the debt securities to one or more other corporations
or  partnerships  within the U.S. Group, by way of loan, for their use for the
general  corporate  purposes of the U.S.  Group.  See "Use of  Proceeds".  The
upstream  operations  of the U.S.  Group are  currently  focused on exploiting
long-life  unconventional natural gas formations in the Jonah field located in
southwest  Wyoming,  the  Piceance  Basin in  northwest  Colorado and the East
Texas,  Fort  Worth and  Maverick  Basins in Texas.  The U.S.  Group  also has
landholdings  in the  Columbia  River basin in  Washington  State,  as well as
interests in natural gas gathering and processing  assets. The majority of the
U.S.  Group's  production is from the following four key resource  plays:  (i)
Jonah; (ii) Piceance; (iii) East Texas; and (iv) Fort Worth.

     The  funds  required  by us to  satisfy  our  obligations  under the debt
securities that we issue under this  prospectus  will be obtained  through our
debt  interests in other members of the U.S.  Group or through other  advances
from  EnCana  Corporation  or  its  subsidiaries  or  partnerships.  Any  debt
securities we issue under this  prospectus  will be fully and  unconditionally
guaranteed by EnCana Corporation.

                              ENCANA CORPORATION

     EnCana  Corporation  is  one  of  North  America's  leading  natural  gas
producers,  is among the largest holders of natural gas and oil resource lands
onshore  North  America  and is a  technical  and cost  leader in the  in-situ
recovery of oilsands  bitumen.  EnCana  pursues  growth from its  portfolio of
long-life  resource plays situated in Canada and the United States.  Contained
in   unconventional   reservoirs,   resource   plays  are   large   contiguous
accumulations of hydrocarbons, located in thick or areally extensive deposits,
that typically have lower  geological and commercial  development  risk, lower
average  long-term  decline rates and very long  producing  lives  compared to
conventional   plays.  EnCana  is  also  engaged  in  select  exploration  and
production activities internationally.

     EnCana  continually  pursues  opportunities  to  develop  and  expand its
business,  which may  include  significant  corporate  or asset  acquisitions.
EnCana may finance such  acquisitions with debt or equity, or a combination of
both.

relating to a series of debt  securities,  we will advance the net proceeds we
receive from the sale of the debt securities to one or more other corporations

may include  capital  expenditures,  the  repayment  of  indebtedness  and the
financing of acquisitions.  The amount of net proceeds to be used for any such
purpose will be described in an applicable prospectus supplement.

                        DESCRIPTION OF DEBT SECURITIES

     In this section only, "EnCana Corporation" and "the Guarantor" refer only
to EnCana Corporation without any of its subsidiaries or partnerships  through
which it operates.  The following  description describes certain general terms
and provisions of the debt  securities.  We will provide the particular  terms
and  provisions of a series of debt  securities  and a description  of how the
general  terms and  provisions  described  below may apply to that series in a
supplement to this prospectus.

     The  debt  securities  will be  issued  under an  indenture  (hereinafter
referred to as the "Indenture")  dated May 3, 2004 among us, the Guarantor and
Deutsche Bank Trust Company Americas,  as "Trustee",  a form of which has been
filed as an  exhibit to the  registration  statement  filed with the SEC.  The
Indenture is subject to and governed by the U.S. Trust  Indenture Act of 1939,
as  amended.  The  following  is a summary of the  Indenture  which  describes
certain  general  terms  and  provisions  of the  debt  securities  and is not
intended to be complete;  these statements are qualified in their entirety by,
and subject to, the provisions of the  Indenture,  including the definition of
capitalized  terms used under this caption.  We urge you to read the Indenture
carefully,  because it is the  Indenture,  and not this summary,  that governs
your rights as a holder of our debt  securities.  See "Where You Can Find More
Information"  in  this  prospectus.   Prospective  investors  should  rely  on
information  in  the  applicable  prospectus  supplement,  which  may  provide
information that is different from this prospectus.

     We may, from time to time,  issue debt  instruments and incur  additional
indebtedness  other than through the issuance of debt  securities  pursuant to
this prospectus.

GENERAL

     The  Indenture  does not limit  the  aggregate  principal  amount of debt
securities (which may include debentures,  notes and other unsecured evidences
of indebtedness) that we may issue under the Indenture.  It provides that debt
securities  may be issued  from time to time in one or more  series and may be
denominated  and  payable in U.S.  dollars or any  foreign  currency.  Special
Canadian and U.S. federal income tax  considerations  applicable to any of our
debt  securities  denominated  in a foreign  currency will be described in the
prospectus supplement relating to any offering of debt securities  denominated
in a foreign currency. The debt securities offered pursuant to this prospectus
will be issued in an amount up to US$2,000,000,000,  or if any debt securities
are offered at original issue discount, such greater amount as shall result in
an aggregate  offering  price of up to  US$2,000,000,000  or the equivalent in
other  currencies.  The  Indenture  also permits us to increase the  principal
amount of any  series of our debt  securities  previously  issued and to issue
that increased principal amount. The applicable prospectus supplement will set
forth the following terms relating to the debt securities being offered by us:

     o     the specific  designation and the aggregate principal amount of the
           debt securities of such series;

     o     the extent and manner, if any, to which payment on or in respect of
           our  debt  securities  of such  series  will be  senior  or will be
           subordinated  to the prior  payment  of our other  liabilities  and
           obligations;

     o     the percentage or percentages of principal amount at which our debt
           securities of such series will be issued;

           of such series to be payable upon a declaration of  acceleration of
           maturity  and/or the  method by which  such date or dates  shall be
           determined or extended;

     o     the rate or rates  (whether  fixed or  variable)  at which our debt
           securities of such series will bear interest,  if any, and the date
           or dates from which such interest will accrue;

     o     the dates on which any  interest  will be payable  and the  regular
           record dates for the payment of interest on our debt  securities of
           such series in registered form;

                                        7



     o     the place or places where the  principal of (and  premium,  if any,
           and interest,  if any, on) our debt securities will be payable, and
           each office or agency where our debt  securities of such series may
           be presented for registration of transfer or exchange;

     o     if  other  than  U.S.  dollars,  the  currency  in  which  our debt
           securities  of such  series are  denominated  or in which  currency
           payment of the principal of (and premium, if any, and interest,  if
           any, on) such debt securities of such series will be payable;

     o     whether our debt  securities of such series will be issuable in the
           form of one or more global  securities  and, if so, the identity of
           the depositary for the global securities;

     o     any mandatory or optional redemption or sinking fund provisions;

     o     the period or periods, if any, within which, the price or prices at
           which,  the  currency  in which and the terms and  conditions  upon
           which  our  debt  securities  of such  series  may be  redeemed  or

           prices at which and the  currency in which our debt  securities  of
           such series are payable;

     o     any index used to determine  the amount of payments of principal of
           (and premium, if any, or interest,  if any, on) our debt securities
           of such series;

     o     the terms, if any, on which our debt securities may be converted or
           exchanged for other of our debt  securities  or debt  securities of
           other entities;

     o     any other terms of our debt  securities  of such series,  including
           covenants  and events of default which apply solely to a particular
           series  of our debt  securities  being  offered  which do not apply
           generally to other debt  securities,  or any covenants or events of
           default generally  applicable to our debt securities of such series
           which do not apply to a particular series of our debt securities;

     o     if other than The Depository Trust Company,  the person  designated
           as the depositary for the debt securities of such series;

     o     any  applicable  material  Canadian  and U.S.  federal  income  tax
           consequences;

     o     whether and under what circumstances we will pay Additional Amounts
           on the debt  securities  of such series in respect of certain taxes
           (and the terms of any such  payment)  and,  if so,  whether we will
           have the option to redeem the debt securities of such series rather
           than pay the Additional Amounts (and the terms of any such option);

     o     whether the payment of our debt  securities  will be  guaranteed by
           any other person in addition to the Guarantor;

     o     whether  the  series of our debt  securities  are to be  registered
           securities,  bearer  securities  (with or without coupons) or both;
           and

     o     if other than  denominations of US$1,000 and any integral  multiple
           thereof,  the  denominations in which any registered  securities of
           the series shall be issuable and, if other than the denomination of
           US$5,000,  the  denomination or  denominations  in which any bearer
           securities of the series shall be issuable.

     Unless otherwise indicated in the applicable prospectus  supplement,  the
Indenture does not afford  holders of our debt  securities the right to tender
such debt securities to us in the event that we have a change in control.

                                      8


     Our debt securities may be issued under the Indenture bearing no interest
or at a discount below their stated  principal  amount.  The Canadian and U.S.
federal income tax consequences and other special considerations applicable to
any such discounted debt securities or other debt securities  offered and sold
at par which are  treated as having  been  issued at a discount  for  Canadian
and/or U.S.  federal  income tax purposes will be described in the  prospectus
supplement relating to the debt securities.

GUARANTEE

     The Guarantor will fully and unconditionally guarantee the payment of the
principal (and premium,  if any) and interest,  if any, on the debt securities
issued by us and any  Additional  Amounts  payable  with  respect to such debt
securities  when they become due and payable,  whether at the stated  maturity
thereof or by declaration of acceleration, notice of redemption or otherwise.

RANKING

     Unless otherwise indicated in an applicable  prospectus  supplement,  the
debt securities will be our unsecured and unsubordinated  obligations and will
rank equally with all of our other unsecured and  unsubordinated  indebtedness
outstanding from time to time.

     The  guarantee  will  be the  Guarantor's  unsubordinated  and  unsecured
obligation  and,  unless  otherwise  provided with respect to a series of debt
securities,  will rank equally with all of the  Guarantor's  other  unsecured,
unsubordinated  obligations.  The Guarantor conducts a substantial  portion of
its business through corporate and partnership  subsidiaries.  The Guarantor's
obligations  under  the  guarantee  will be  structurally  subordinate  to all
existing and future  indebtedness  and  liabilities of any of the  Guarantor's
corporate and partnership subsidiaries.

DEBT SECURITIES IN GLOBAL FORM

THE DEPOSITARY, BOOK-ENTRY AND SETTLEMENT

     A series  of our debt  securities  may be  issued  in whole or in part in
global form as a "global  security"  and will be registered in the name of and
be  deposited  with a  depositary,  or its  nominee,  each  of  which  will be
identified in the prospectus  supplement  relating to that series.  Unless and
until  exchanged,  in whole or in part, for our debt  securities in definitive
registered form, a global security may not be transferred except as a whole by
the depositary for such global security to a nominee of the  depositary,  by a
nominee  of the  depositary  to  the  depositary  or  another  nominee  of the
depositary  or by the  depositary  or any such  nominee to a successor  of the
depositary or a nominee of the successor.

     The  specific  terms of the  depositary  arrangement  with respect to any
portion of a particular  series of our debt  securities to be represented by a
global security will be described in a prospectus  supplement relating to such
series.  We  anticipate  that  the  following  provisions  will  apply  to all
depositary arrangements.

     Upon the issuance of a global  security,  the depositary  therefor or its
nominee will credit, on its book entry and registration system, the respective
principal amounts of our debt securities represented by the global security to
the accounts of such persons,  designated as  "participants",  having accounts
with such depositary or its nominee.  Such accounts shall be designated by the
underwriters,  dealers or agents participating in the distribution of our debt
securities or by us if such debt  securities  are offered and sold directly by
us. Ownership of beneficial  interests in a global security will be limited to
participants   or  persons  that  may  hold   beneficial   interests   through
participants.  Ownership of beneficial  interests in a global security will be
shown on, and the transfer of that  ownership  will be effected  only through,
records maintained by the depositary  therefor or its nominee (with respect to
interests of  participants)  or by  participants  or persons that hold through
participants  (with respect to interests of persons other than  participants).
The  laws of some  states  in the  United  States  may  require  that  certain
purchasers  of  securities  take  physical  delivery  of  such  securities  in
definitive form.

     So long as the  depositary  for a global  security  or its nominee is the
registered owner of the global security,  such depositary or such nominee,  as
the case may be,  will be  considered  the sole  owner or  holder  of the debt
securities  represented  by the global  security  for all  purposes  under the
Indenture.  Except as provided  below,  owners of  beneficial  interests  in a
global  security will not be entitled to have a series of our debt  securities
represented by the global security

                                       9


registered in their names, will not receive or be entitled to receive physical
delivery of such series of our debt securities in definitive form and will not
be considered the owners or holders thereof under the Indenture.

PAYMENTS OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST

     Any  payments  of  principal,  premium,  if any,  and  interest on global
securities  registered in the name of a depositary or its nominee will be made
to the depositary or its nominee,  as the case may be, as the registered owner
of the global  security  representing  such debt  securities.  None of us, the
Guarantor, the Trustee or any paying agent for our debt securities represented
by the global  securities  will have any  responsibility  or liability for any
aspect of the records  relating to or payments  made on account of  beneficial
ownership interests of the global security or for maintaining,  supervising or
reviewing any records relating to such beneficial ownership interests.

     We expect that the depositary for a global security or its nominee,  upon
receipt of any payment of principal, premium, if any, or interest, will credit
participants'  accounts  with  payments  in  amounts  proportionate  to  their
respective beneficial interests in the principal amount of the global security
as shown on the records of such depositary or its nominee. We also expect that
payments  by  participants  to  owners  of  beneficial  interests  in a global
security  held  through  such   participants  will  be  governed  by  standing
instructions and customary practices,  as is now the case with securities held
for the accounts of customers  registered  in "street  name",  and will be the
responsibility of such participants.

DISCONTINUANCE OF DEPOSITARY'S SERVICES

     If a depositary for a global security representing a particular series of
our  debt  securities  is at any time  unwilling  or  unable  to  continue  as
depositary  and a successor  depositary is not appointed by us within 90 days,
we will  issue  such  series  of our debt  securities  in  definitive  form in
exchange  for  a  global  security   representing  such  series  of  our  debt
securities.  In  addition,  we may  at any  time  and in our  sole  discretion
determine not to have a series of our debt securities  represented by a global
security  and, in such event,  will issue a series of our debt  securities  in
definitive form in exchange for all of the global securities  representing the
series of debt securities.

DEBT SECURITIES IN DEFINITIVE FORM

     A series  of our debt  securities  may be  issued  solely  as  registered
securities,  solely as bearer securities or as both registered  securities and
bearer securities.  Registered securities will be issuable in denominations of
US$1,000 and integral  multiples  of US$1,000  and bearer  securities  will be
issuable  in  denominations  of  US$5,000  or,  in each  case,  in such  other
denominations  as may be set out in the  terms of the debt  securities  of any
particular  series.  Unless otherwise  indicated in the applicable  prospectus
supplement, bearer securities will have interest coupons attached.

     A prospectus supplement may indicate the places to register a transfer of
our  debt  securities.  Except  for  certain  restrictions  set  forth  in the
Indenture,  no service charge will be made for any registration of transfer or
exchange of our debt securities,  but we may, in certain instances,  require a
sum  sufficient  to cover any tax or other  governmental  charges  payable  in
connection with these transactions.

     We shall not be required to:

     o     issue,  register the transfer of or exchange any series of our debt
           securities  during a period beginning at the opening of business 15
           days before any selection of that series of our debt  securities to
           be  redeemed  and  ending  at the close of  business  on (i) if the
           series  of our debt  securities  are  issuable  only as  registered
           securities, the day of mailing of the relevant notice of redemption
           and (ii) if the  series  of our debt  securities  are  issuable  as
           bearer securities, the day of the first publication of the relevant
           notice of redemption  or, if the series of our debt  securities are
           also issuable as registered securities and there is no publication,
           the mailing of the relevant notice of redemption;

     o     register the transfer of or exchange any  registered  security,  or
           portion  thereof,  called for  redemption,  except  the  unredeemed
           portion of any registered security being redeemed in part;

                                      10


     o     exchange any bearer security selected for redemption,  except that,
           to the extent provided with respect to such bearer  security,  such
           bearer security may be exchanged for a registered  security of that
           series and like tenor, PROVIDED that such registered security shall
           be immediately  surrendered for redemption with written instruction
           for payment consistent with the provisions of the Indenture; or

     o     issue,  register  the  transfer  of or  exchange  any of  our  debt
           securities  which have been surrendered for repayment at the option
           of the holder,  except the  portion,  if any,  thereof not to be so
           repaid.

     Unless  otherwise  indicated  in the  applicable  prospectus  supplement,
payment  of any  interest  will be made to the  persons in whose name our debt
securities  are  registered  at the  close  of  business  on the  day or  days
specified by us.

     Set forth below is a summary of certain of the defined  terms used in the
Indenture.  We urge you to read the Indenture  for the full  definition of all
such terms.

any  person  on a  consolidated  basis  (less  applicable  reserves  and other
properly deductible items) after deducting therefrom:

     o     all current liabilities (excluding any indebtedness classified as a
           current  liability and any current  liabilities  which are by their
           terms  extendible or renewable at the option of the obligor thereon
           to a time more than 12 months after the time as of which the amount

COVENANTS

LIMITATION ON LIENS

     The  Indenture  provides that so long as any of our debt  securities  are
outstanding and subject to the provisions of the Indenture, the Guarantor will
not, and will not permit any of its Restricted Subsidiaries to, create, incur,
assume or otherwise have  outstanding any Lien securing any  indebtedness  for
borrowed money or interest  thereon (or any liability of the Guarantor or such
Restricted  Subsidiaries  under the related  guarantee or endorsement or other
instrument  under which the  Guarantor  or such  Restricted  Subsidiaries  are
contingently  liable,  either  directly or  indirectly,  for borrowed money or
interest thereon),  other than Permitted Liens, without also simultaneously or
prior thereto  securing,  or causing such  Restricted  Subsidiaries to secure,
indebtedness  under the  Indenture  so that our debt  securities  are  secured
equally and ratably with or prior to such other indebtedness,  except that the
Guarantor  and  its  Restricted  Subsidiaries  may  incur  a  Lien  to  secure
indebtedness for borrowed money without securing our debt securities if, after
giving effect thereto, the principal amount of indebtedness for borrowed money
secured by Liens created,  incurred or assumed after the date of the Indenture
and  otherwise  prohibited  by  the  Indenture  does  not  exceed  10%  of the

                                      14


     Notwithstanding  the foregoing,  transactions such as the sale (including
any  forward  sale)  or other  transfer  of (i) oil,  gas,  minerals  or other
resources of a primary nature, whether in place or when produced, for a period
of time until, or in an amount such that, the purchaser will realize therefrom
a  specified   amount  of  money  or  a  specified  rate  of  return  (however
determined),  or a  specified  amount of such  oil,  gas,  minerals,  or other
resources of a primary  nature,  or (ii) any other interest in property of the
character commonly referred to as a "production payment",  will not constitute
a Lien and will not result in the Guarantor or a Restricted  Subsidiary  being
required to secure the debt securities.

CONSOLIDATION, AMALGAMATION, MERGER AND SALE OF ASSETS

     Neither we nor the Guarantor may  consolidate or amalgamate with or merge
into or enter into any statutory  arrangement with any other  corporation,  or
convey, transfer or lease all or substantially all our or the Guarantor's,  as
the case may be, properties and assets to any person, unless:

     o     the  entity  formed by or  continuing  from such  consolidation  or
           amalgamation or into which we or the Guarantor (as the case may be)
           are merged or with which we or the  Guarantor  (as the case may be)
           enter into such statutory  arrangement or the person which acquires
           or  leases  all or  substantially  all  of  our or the  Guarantor's
           properties  and  assets  (as  the  case  may be) is  organized  and
           existing under the laws of the United States,  any state thereof or
           the  District of Columbia or the laws of Canada or any  province or
           territory thereof, or, if such consolidation, amalgamation, merger,
           statutory  arrangement  or other  transaction  would not impair the
           rights of the holders of our debt securities, in any other country,
           PROVIDED that if such successor  entity is organized under the laws
           of a jurisdiction  other than the United States,  any state thereof
           or the District of Columbia,  or the laws of Canada or any province
           or  territory  thereof,  the  successor  entity  assumes our or the
           Guarantor's  obligations  (as the  case  may  be)  under  the  debt
           securities  and the Indenture to pay Additional  Amounts,  with the
           name of such successor  jurisdiction  being included in addition to
           Canada  in  each  place  that  Canada  appears  in "--  Payment  of
           Additional Amounts" below;

     o     the successor entity  expressly  assumes or assumes by operation of
           law all of our or the Guarantor's  obligations (as the case may be)
           under our debt securities, the guarantee and the Indenture;

     o     immediately before and after giving effect to such transaction,  no
           event of default, and no event which, after notice or lapse of time
           or both, would become an event of default,  shall have happened and
           be continuing; and

     o     certain other conditions are met.

     If, as a result of any such  transaction,  any of the  Guarantor's or its
Restricted Subsidiaries' Restricted Properties become subject to a Lien, then,
unless  such  Lien  could be  created  pursuant  to the  Indenture  provisions
described  under the  "LIMITATION ON LIENS" covenant above without equally and
ratably securing our debt securities,  the Guarantor,  simultaneously  with or
prior to such  transaction,  will secure,  or cause the applicable  Restricted
Subsidiary to secure, our debt securities equally and ratably with or prior to
the indebtedness secured by such Lien.

PAYMENT OF ADDITIONAL AMOUNTS

     Unless otherwise specified in the applicable prospectus  supplement,  all
payments made by or on behalf of us or the Guarantor  under or with respect to
any series of our debt  securities or related  guarantee will be made free and
clear of and without withholding or deduction for or on account of any present
or future tax, duty, levy,  impost,  assessment or other  governmental  charge
(including penalties,  interest and other liabilities related thereto) imposed
or  levied  by or on behalf of the  Government  of Canada or any  province  or
territory  thereof or by any  authority  or agency  therein or thereof  having
power to tax (hereinafter  "Canadian Taxes"),  unless we or the Guarantor,  as
the case may be, are required to withhold or deduct  Canadian  Taxes by law or
by the interpretation or administration  thereof.  If we or the Guarantor,  as
the case may be, are so  required  to  withhold or deduct any amount for or on
account of Canadian  Taxes from any payment  made under or with respect to the
debt  securities or guarantee,  we or the Guarantor,  as the case may be, will
pay to each  holder  of such  debt  securities  as  additional  interest  such
additional amounts ("Additional  Amounts") as may be necessary so that the net
amount  received by each such holder after such  withholding or deduction (and
after deducting any Canadian Taxes on such

                                      15


Additional  Amounts)  will not be less than the amount such holder  would have
received if such Canadian Taxes had not been withheld or deducted. However, no
Additional  Amounts  will be payable  with respect to a payment made to a debt
securities  holder  (such  holder,  an  "Excluded  Holder")  in respect of the
beneficial owner thereof:

     o     with which we or the Guarantor,  as the case may be, do not deal at
           arm's length (for the  purposes of the INCOME TAX ACT  (Canada)) at
           the time of the making of such payment;

     o     which is  subject  to such  Canadian  Taxes by  reason  of the debt
           securities  holder  being a resident,  domicile or national  of, or
           engaged in business or  maintaining  a permanent  establishment  or
           other physical presence in or otherwise having some connection with
           Canada or any province or territory  thereof  otherwise than by the
           mere  holding of the debt  securities  or the  receipt of  payments
           thereunder; or

     o     which is  subject  to such  Canadian  Taxes by  reason  of the debt
           securities  holder's  failure  to  comply  with any  certification,
           identification,  documentation  or other reporting  requirements if
           compliance is required by law, regulation,  administrative practice
           or an applicable  treaty as a precondition  to exemption from, or a
           reduction in the rate of deduction or withholding of, such Canadian
           Taxes.

     We or the Guarantor, as the case may be, will also:

     o     make such withholding or deduction; and

     o     remit  the  full  amount  deducted  or  withheld  to  the  relevant
           authority in accordance with applicable law.

     We or the  Guarantor,  as the case may be, will furnish to the holders of
the debt securities, within 60 days after the date the payment of any Canadian
Taxes is due pursuant to applicable law,  certified  copies of tax receipts or
other documents  evidencing  such payment by us or the Guarantor,  as the case
may be.

     We and the Guarantor will indemnify and hold harmless each holder of debt
securities  (other than an Excluded Holder) and upon written request reimburse
each such holder for the amount  (excluding any  Additional  Amounts that have
previously been paid by us or the Guarantor with respect thereto) of:

     o     the  payment  of any  Canadian  Tax,  together  with any  interest,
           penalties and reasonable expenses in connection therewith; and

     o     any Canadian Taxes imposed with respect to any reimbursement  under
           the preceding clause, but excluding any such Canadian Taxes on such
           holder's net income.

     In any event, no Additional  Amounts or indemnity amounts will be payable
in excess of  Additional  Amounts  or the  indemnity  amounts  which  would be
required if the holder of debt  securities was a resident of the United States
for purposes of the Canada-U.S. Income Tax Convention (1980), as amended.

     Wherever in the Indenture,  the debt securities or the guarantee there is
mentioned,  in any context,  the payment of principal  (and premium,  if any),
interest,  if any, or any other amount payable under or with respect to a debt
security or guarantee,  such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context,  Additional
Amounts are, were or would be payable in respect thereof.

TAX REDEMPTION

     Unless otherwise  specified in the applicable  prospectus  supplement,  a
series of our debt  securities  will be subject to  redemption at any time, in
whole but not in part,  at a redemption  price equal to the  principal  amount
thereof  together  with  accrued  and  unpaid  interest  to the date fixed for
redemption, upon the giving of a notice as described below, if:

     o     as a  result  of any  change  in or  amendment  to the laws (or any
           regulations or rulings promulgated  thereunder) of Canada or of any
           political  subdivision  or  taxing  authority  thereof  or  therein
           affecting

                                      16


           taxation,   or  any  change  in  official  position  regarding  the
           application or interpretation of such laws,  regulations or rulings
           (including a holding by a court of competent  jurisdiction),  which
           change or amendment  is announced or becomes  effective on or after
           the date specified in the applicable prospectus supplement, we have
           or will  become  obligated  to pay (or  the  Guarantor  has or will
           become obligated to pay, as the case may be) on the next succeeding
           date on which interest is due,  Additional  Amounts with respect to
           any debt security of such series as described  under "-- Payment of
           Additional Amounts"; or

     o     on or  after  the  date  specified  in  the  applicable  prospectus
           supplement,  any action has been taken by any taxing  authority of,
           or  any  decision  has  been  rendered  by  a  court  of  competent
           jurisdiction  in Canada,  or any  political  subdivision  or taxing
           authority  thereof  or  therein,  including  any of  those  actions
           specified in the paragraph  immediately above,  whether or not such
           action was taken or decision  was  rendered  with respect to us (or
           the  Guarantor,  as the  case may be),  or any  change,  amendment,
           application or interpretation shall be officially proposed,  which,
           in any such case, in the written  opinion to us (or the  Guarantor,
           as the case may be) of legal counsel of recognized  standing,  will
           result  in our (or the  Guarantor,  as the  case  may be)  becoming
           obligated to pay, on the next  succeeding date on which interest is
           due,  Additional  Amounts with respect to any debt security of such
           series;

and, in any such case, we, in our business judgment, or the Guarantor,  in its
business  judgment,  as the case may be, determine that such obligation cannot
be avoided by the use of reasonable measures available to us.

     In the  event  that we elect to  redeem a series  of our debt  securities
pursuant to the  provisions  set forth in the  preceding  paragraph,  we shall
deliver to the Trustee a certificate, signed by an authorized officer, stating
that we are entitled to redeem such series of our debt securities  pursuant to
their terms.

     Notice of intention to redeem such series of our debt  securities will be
given  not more  than 60 nor less  than 30 days  prior to the date  fixed  for
redemption and will specify the date fixed for redemption.

PROVISION OF FINANCIAL INFORMATION

     The Guarantor  will file with the Trustee,  within 15 days after it files
them with the SEC, copies,  which may be in electronic  format,  of its annual
report and of the information,  documents and other reports (or copies of such
portions  of any of the  foregoing  as the SEC may by  rules  and  regulations
prescribe) which it is required to file with the SEC pursuant to Section 13 or
15(d) of the  Exchange  Act.  Notwithstanding  that the  Guarantor  may not be
required  to remain  subject to the  reporting  requirements  of Section 13 or
15(d) of the Exchange Act or otherwise report on an annual and quarterly basis
on forms  provided for such annual and quarterly  reporting  pursuant to rules
and regulations promulgated by the SEC, the Guarantor will continue to provide
the Trustee:

     o     within 140 days after the end of each fiscal year, the  information
           required to be contained in annual reports on Form 20-F,  Form 40-F
           or Form 10-K as applicable (or any successor form); and

     o     within  65 days  after the end of each of the  first  three  fiscal
           quarters  of each  fiscal  year,  the  information  required  to be
           contained  in reports on Form 6-K (or any  successor  form)  which,
           regardless of applicable requirements shall, at a minimum,  contain
           such information required to be provided in quarterly reports under
           the laws of Canada or any province thereof to security holders of a
           corporation  with securities  listed on the Toronto Stock Exchange,
           whether or not the  Guarantor has any of its  securities  listed on
           such exchange. Such information will be prepared in accordance with
           Canadian disclosure requirements and GAAP; PROVIDED,  HOWEVER, that
           the  Guarantor  shall not be obligated to file such report with the
           SEC if the SEC does not permit such filings.


EVENTS OF DEFAULT

     The following are summaries of events of default under the Indenture with
respect to any series of our debt securities:

                                      17


     o     default in the payment of any interest on any debt security of that
           series when it becomes due and  payable,  and  continuance  of such
           default for a period of 30 days;

     o     default in the payment of the  principal  of (or  premium,  if any,
           on),  any debt  security  of that  series  when it becomes  due and
           payable;

     o     default  in  the  performance,  or  breach,  of  any  of our or the
           Guarantor's  covenants or warranties in the Indenture in respect of
           our debt  securities  of that  series  (other  than a  covenant  or
           warranty  a default  in the  performance  of which or the breach of
           which is specifically  dealt with elsewhere in the Indenture),  and
           continuance of such default or breach for a period of 60 days after
           receipt by us and the Guarantor of written notice,  specifying such
           default or breach, by the Trustee or by the holders of at least 25%
           in  principal  amount of all  outstanding  debt  securities  of any
           series affected thereby;

     o     if an event of default (as defined in any  indenture or  instrument
           under  which  we,  or the  Guarantor,  or  any  of  its  Restricted
           Subsidiaries,  has at the time of the Indenture or shall thereafter
           have  outstanding any indebtedness for borrowed money) shall happen
           and be  continuing,  or we,  or the  Guarantor,  or any  Restricted
           Subsidiary shall have failed to pay principal  amounts with respect
           to such  indebtedness  at  maturity  and such  event of  default or
           failure to pay shall result in such indebtedness being declared due
           and payable or otherwise being accelerated, in either event so that
           an amount in excess of the greater of  US$75,000,000  and 2% of the
           Guarantor's Shareholders' Equity shall be or become due and payable
           upon such declaration or otherwise accelerated prior to the date on
           which the same would  otherwise  have become due and  payable  (the
           "accelerated  indebtedness"),  and such  acceleration  shall not be
           rescinded or  annulled,  or such event of default or failure to pay
           under such indenture or instrument  shall not be remedied or cured,
           whether by payment or  otherwise,  or waived by the holders of such
           accelerated indebtedness,  then (i) if the accelerated indebtedness
           shall be as a result of an event of default which is not related to
           the  failure to pay  principal  or  interest  on the terms,  at the
           times,  and on the  conditions  set out in any  such  indenture  or
           instrument,  it shall not be  considered  an event of  default  for
           purposes of the Indenture until 30 days after such indebtedness has
           been  accelerated,  or (ii) if the accelerated  indebtedness  shall
           occur as a result of such  failure to pay  principal or interest or
           as a result of an event of default  which is related to the failure
           to pay principal or interest on the terms, at the times, and on the
           conditions set out in any such indenture or instrument, then (A) if
           such accelerated  indebtedness is, by its terms,  Non-Recourse Debt
           to us, the Guarantor or its Restricted  Subsidiaries,  it shall not
           be considered an event of default for purposes of the Indenture; or
           (B) if  such  accelerated  indebtedness  is  recourse  to  us,  the
           Guarantor  or  its  Restricted  Subsidiaries,  any  requirement  in
           connection  with such  failure to pay or event of  default  for the
           giving  of  notice  or the  lapse of time or the  happening  of any
           further  condition,  event or act under  such  other  indenture  or
           instrument in  connection  with such failure to pay principal or an
           event of default  shall be  applicable  together with an additional
           seven days before being considered an event of default for purposes
           of the Indenture;

     o     the entry of decree or order by a court having  jurisdiction in the
           premises adjudging us or the Guarantor a bankrupt or insolvent,  or
           approving  as  properly  filed a petition  seeking  reorganization,
           arrangement,  adjustment or  composition  of or in respect of us or
           the Guarantor under the BANKRUPTCY AND INSOLVENCY ACT (Canada), the
           COMPANIES'   CREDITORS   ARRANGEMENT  ACT  (Canada)  or  any  other
           applicable  insolvency  law, or appointing a receiver,  liquidator,
           assignee, trustee,  sequestrator (or similar official) of us or the
           Guarantor or of any  substantial  part of the property of us or the
           Guarantor, or ordering the winding up or liquidation of the affairs
           of us or the Guarantor,  and the  continuance of any such decree or
           order unstayed and in effect for a period of 90 consecutive days;

     o     the  institution  by us  or  the  Guarantor  of  proceedings  to be
           adjudicated a bankrupt or insolvent, or the consent by either us or
           the  Guarantor  to the  institution  of  bankruptcy  or  insolvency
           proceedings against us or the Guarantor, or the filing by us or the
           Guarantor of a petition or answer or consent seeking reorganization
           or relief under the BANKRUPTCY  AND  INSOLVENCY  ACT (Canada),  the
           COMPANIES'   CREDITORS   ARRANGEMENT  ACT  (Canada)  or  any  other
           applicable insolvency law, or the consent by us or the Guarantor to
           the  filing  of  any  such  petition  or to  the  appointment  of a
           receiver,  liquidator,

                                      18


           assignee,  trustee,  sequestrator (or other similar official) of us
           or the  Guarantor  or of any  substantial  part of the  property of
           either us or the Guarantor,  respectively,  or the making by either
           us or the Guarantor of an assignment  for the benefit of creditors,
           or the admission by it in writing of its inability to pay its debts
           generally as they become due; or

     o     any  other  events  of  default   provided  with  respect  to  debt
           securities of that series.

     If an event of default under the Indenture  occurs and is continuing with
respect to any series of our debt securities,  then and in every such case the
Trustee or the holders of at least 25% in  aggregate  principal  amount of the
outstanding  debt  securities  of such  affected  series  may,  subject to any
subordination  provisions thereof, declare the entire principal amount (or, if
the  debt   securities  of  that  series  are  original  issue  discount  debt
securities,  such portion of the  principal  amount as may be specified in the
terms of that  series) of all debt  securities  of such series and all accrued
and unpaid interest thereon to be immediately due and payable. However, at any
time after a  declaration  of  acceleration  with respect to any series of our
debt  securities has been made, but before a judgment or decree for payment of
the money due has been obtained, the holders of a majority in principal amount
of the outstanding  debt  securities of that series,  by written notice to us,
the Guarantor and the Trustee  under  certain  circumstances,  may rescind and
annul such acceleration.

     Reference is made to the applicable  prospectus supplement or supplements
relating  to each  series  of our debt  securities  which are  original  issue
discount  debt   securities   for  the  particular   provisions   relating  to
acceleration  of the  maturity  of a portion of the  principal  amount of such
original issue discount securities upon the occurrence of any event of default
and the continuation thereof.

     Subject to certain limitations set forth in the Indenture, the holders of
a majority in  principal  amount of the  outstanding  debt  securities  of all
series  affected  by an event of  default  shall  have the right to direct the
time,  method and place of conducting any proceeding for any remedy  available
to the Trustee,  or  exercising  any trust or power  conferred on the Trustee,
with respect to the debt  securities  of all series  affected by such event of
default.

     No  holder  of a debt  security  of any  series  will  have any  right to
institute any proceeding with respect to the Indenture, or for the appointment
of a receiver or a Trustee, or for any other remedy thereunder, unless:

     o     such holder has previously given to the Trustee written notice of a
           continuing  event of default with respect to the debt securities of
           such series affected by such event of default;

     o     the holders of at least 25% in  aggregate  principal  amount of the
           outstanding  debt  securities of such series  (voting as one class)
           affected by such event of default  have made written  request,  and
           such holder or holders have offered  reasonable  indemnity,  to the
           Trustee to institute such proceeding as Trustee; and

     o     the Trustee has failed to institute  such  proceeding,  and has not
           received  from the  holders of a majority  in  aggregate  principal
           amount of the  outstanding  debt securities of such series affected
           by such  event  of  default  a  direction  inconsistent  with  such
           request, within 60 days after such notice, request and offer.

     However,  such  above-mentioned  limitations  do  not  apply  to  a  suit
instituted by the holder of a debt security for the  enforcement of payment of
the  principal of or any premium or interest on such debt security on or after
the applicable due date specified in such debt security.

     We and the Guarantor will annually  furnish to the Trustee a statement by
certain of our and the  Guarantor's  officers  as to whether or not we and the
Guarantor,  to the  best  of  their  knowledge,  are in  compliance  with  all
conditions  and covenants of the Indenture  and, if not,  specifying  all such
known defaults.

DEFEASANCE AND COVENANT DEFEASANCE

     Unless otherwise specified in the applicable prospectus  supplement,  the
Indenture  provides  that,  at our  or  the  Guarantor's  option,  we and  the
Guarantor  will be discharged  from any and all  obligations in respect of the
outstanding debt

                                      19


securities of any series upon irrevocable  deposit with the Trustee, in trust,
of money and/or  government  securities  which will provide money in an amount
sufficient  in the  opinion of a  nationally  recognized  firm of  independent
chartered  accountants (as evidenced by an officer's  certificate delivered to
the  Trustee)  to pay  the  principal  of  (and  premium,  if  any,  and  each
installment of interest,  if any, on) the outstanding  debt securities of such
series (hereinafter referred to as a "defeasance") (except with respect to the
authentication,  transfer,  exchange or replacement of our debt  securities or
the maintenance of a place of payment and certain other  obligations set forth
in the Indenture). Such trust may only be established if among other things:

     o     we or the  Guarantor  have  delivered  to the Trustee an opinion of
           counsel in the United  States  stating that (i) we or the Guarantor
           have received  from,  or there has been  published by, the Internal
           Revenue  Service a ruling,  or (ii) since the date of  execution of
           the  Indenture,  there  has been a change  in the  applicable  U.S.
           federal  income  tax law,  in either  case to the  effect  that the
           holders of the outstanding  debt securities of such series will not
           recognize income, gain or loss for U.S. federal income tax purposes
           as a result of such defeasance and will be subject to U.S.  federal
           income tax on the same amounts,  in the same manner and at the same
           times  as would  have  been  the  case if such  defeasance  had not
           occurred;

     o     we or the  Guarantor  have  delivered  to the Trustee an opinion of
           counsel in Canada or a ruling from the Canada Revenue Agency to the
           effect that the holders of the outstanding  debt securities of such
           series will not recognize income, gain or loss for Canadian federal
           or  provincial  income  or other tax  purposes  as a result of such
           Defeasance  and will be subject to Canadian  federal or  provincial
           income and other tax on the same amounts, in the same manner and at
           the same times as would have been the case had such  defeasance not
           occurred  (and for the  purposes  of such  opinion,  such  Canadian
           counsel  shall  assume  that  holders  of  the   outstanding   debt
           securities of such series  include  holders who are not resident in
           Canada);

     o     no event of default or event that,  with the passing of time or the
           giving of notice,  or both,  shall  constitute  an event of default
           shall have  occurred and be continuing on the date of such deposit;
           and

     o     neither we nor the  Guarantor is an "insolvent  person"  within the
           meaning of the  BANKRUPTCY  AND INSOLVENCY ACT (Canada) on the date
           of such deposit or at any time during the period ending on the 91st
           day following such deposit.

     We or the Guarantor may exercise the  defeasance  option  notwithstanding
the  prior  exercise  of  the  Covenant  Defeasance  option  described  in the
following paragraph if the conditions  described in the preceding sentence are
met at the time we or the Guarantor exercise the defeasance option.

     The Indenture provides that, at our or the Guarantor's option, unless and
until we have  exercised  our  Defeasance  option  described in the  preceding
paragraph,  we or the Guarantor,  as  applicable,  may omit to comply with the
"LIMITATION  ON  LIENS"  covenant,  certain  aspects  of  the  "CONSOLIDATION,
AMALGAMATION,  MERGER AND SALE OF ASSETS" covenant and certain other covenants
and such  omission  shall not be deemed  to be an event of  default  under the
Indenture and the outstanding  debt securities and guarantee upon  irrevocable
deposit with the Trustee,  in trust,  of money  and/or  government  securities
which  will  provide  money  in an  amount  sufficient  in  the  opinion  of a
nationally  recognized firm of independent chartered accountants (as evidenced
by an officer's  certificate delivered to the Trustee) to pay the principal of
(and  premium,  if any,  and each  installment  of  interest,  if any, on) the
outstanding   debt   securities   (hereinafter   referred   to  as   "covenant
defeasance").  If we or the Guarantor exercise the covenant defeasance option,
the obligations  under the Indenture other than with respect to such covenants
and the events of  default  other than with  respect to such  covenants  shall
remain in full force and effect.  Such trust may only be established if, among
other things:

     o     we or the  Guarantor  have  delivered  to the Trustee an opinion of
           counsel in the United  States to the effect that the holders of the
           outstanding debt securities will not recognize income, gain or loss
           for U.S.  federal  income tax purposes as a result of such covenant
           defeasance  and will be subject to U.S.  federal  income tax on the
           same  amounts,  in the same  manner  and at the same times as would
           have been the case if such covenant defeasance had not occurred;

                                      20


     o     we or the  Guarantor  have  delivered  to the Trustee an opinion of
           counsel in Canada or a ruling from the Canada Revenue Agency to the
           effect that the holders of the outstanding debt securities will not
           recognize  income,  gain or loss for Canadian federal or provincial
           income  or  other  tax  purposes  as  a  result  of  such  covenant
           defeasance  and will be subject to Canadian  federal or  provincial
           income and other tax on the same amounts, in the same manner and at
           the  same  times  as would  have  been  the case had such  covenant
           defeasance not occurred (and for the purposes of such opinion, such
           Canadian  counsel shall assume that holders of the outstanding debt
           securities include holders who are not resident in Canada);

     o     no event of default or event that,  with the passing of time or the
           giving of notice,  or both,  shall  constitute  an event of default
           shall have  occurred and be continuing on the date of such deposit;
           and

     o     neither we nor the  Guarantor is an "insolvent  person"  within the
           meaning of the  BANKRUPTCY  AND INSOLVENCY ACT (Canada) on the date
           of such deposit or at any time during the period ending on the 91st
           day following such deposit.

MODIFICATION AND WAIVER

     Modifications  and  amendments  of the  Indenture  may be made by us, the
Guarantor  and the  Trustee  with the  consent of the holders of a majority in
principal  amount of the  outstanding  debt  securities  of each series issued
under the Indenture  affected by such modification or amendment (voting as one
class); PROVIDED, HOWEVER, that no such modification or amendment may, without
the consent of the holder of each  outstanding  debt security of such affected
series:

     o     change the stated  maturity of the principal of, or any installment
           of interest, if any, on any debt security;

     o     reduce the principal amount of (or premium, if any, or interest, if
           any, on) any debt security;

     o     reduce the amount of  principal  of a debt  security  payable  upon
           acceleration of the maturity thereof;

     o     change the place of payment;

     o     change the currency of payment of principal of (or premium, if any,
           or interest, if any, on) any debt security;

     o     impair  the  right to  institute  suit for the  enforcement  of any
           payment on or with respect to any debt security;

     o     reduce the  percentage  of  principal  amount of  outstanding  debt
           securities  of such series,  the consent of the holders of which is
           required for modification or amendment of the applicable  Indenture
           or  for  waiver  of  compliance  with  certain  provisions  of  the
           Indenture or for waiver of certain defaults; or

     o     modify any provisions of the Indenture relating to the modification
           and  amendment of the  Indenture or the waiver of past  defaults or
           covenants except as otherwise specified in the Indenture.

     The holders of a majority in  principal  amount of our  outstanding  debt
securities  of any series may on behalf of the holders of all debt  securities
of that series waive, insofar as that series is concerned, compliance by us or
the  Guarantor  with certain  restrictive  provisions  of the  Indenture.  The
holders of a majority in principal  amount of outstanding  debt  securities of
any series may waive any past default under the Indenture with respect to that
series,  except a default in the payment of the  principal of (or premium,  if
any) and  interest,  if any, on any debt security of that series or in respect
of a provision which under the Indenture cannot be modified or amended without
the consent of the holder of each  outstanding  debt  security of that series.
The Indenture or the debt securities may be amended or  supplemented,  without
the consent of any holder of such debt  securities,  in order to,  among other
things,  cure any  ambiguity or  inconsistency  or to make any change,  in any
case,  that does not have a  materially  adverse  effect on the  rights of any
holder of such debt securities.

                                      21


CONSENT TO JURISDICTION AND SERVICE

     Under  the  Indenture,  we  and  the  Guarantor  irrevocably  appoint  CT
Corporation  System, 111 - 8th Avenue,  13th Floor, New York, New York, as our
and the  Guarantor's  authorized  agent for  service of process in any suit or
proceeding  arising out of or relating to the debt securities or the Indenture
and for actions brought under federal or state  securities laws in any federal
or state court  located in New York,  New York and  irrevocably  submit to the
non-exclusive jurisdiction of any such court.

GOVERNING LAW

     Our debt  securities  and the Indenture will be governed by and construed
in accordance with the laws of the State of New York.

ENFORCEABILITY OF JUDGMENTS

     Since most of the Guarantor's  assets,  as well as the assets of a number
of our and the  Guarantor's  directors  and  officers,  are outside the United
States,  any judgment  obtained in the United States against us, the Guarantor
or  certain  of  our or  the  Guarantor's  directors  or  officers,  including
judgments with respect to the payment of principal on any debt securities, may
not be collectible within the United States.

     We have been  informed  by  Macleod  Dixon LLP,  our and the  Guarantor's
Canadian counsel,  that there is doubt as to the enforceability in Canada by a
court in original actions, or in actions to enforce judgments of United States
courts, of civil liabilities  predicated solely upon the United States federal
securities  laws.  Therefore,  it may not be possible to enforce those actions
against us or the Guarantor,  our or the Guarantor's directors and officers or
the experts named in this prospectus.

     Because  the  Trustee  is located  in the  United  States,  it may not be
possible for  purchasers of our debt  securities  outside the United States to
effect  service of process  outside the United  States upon the Trustee nor to
enforce against the Trustee,  outside the United States, judgments obtained in
courts  outside  the United  States.  Also,  it may not be possible to enforce
judgments of non-U.S. courts against the Trustee in the United States.

                                 RISK FACTORS

     IN ADDITION TO THE RISK FACTORS SET FORTH BELOW,  ADDITIONAL RISK FACTORS
RELATING  TO  THE  BUSINESS  OF  ENCANA  ARE  DISCUSSED  IN  ENCANA'S   ANNUAL
INFORMATION FORM AND ENCANA'S MANAGEMENT'S DISCUSSION AND ANALYSIS, WHICH RISK
FACTORS ARE INCORPORATED  HEREIN BY REFERENCE.  Prospective  purchasers of the
debt securities should consider  carefully the risk factors set forth below as
well as the other  information  contained in and  incorporated by reference in
this prospectus and in the applicable  prospectus supplement before purchasing
the debt  securities  offered  hereby.  If any event  arising from these risks
occurs, our or EnCana's business,  prospects,  financial condition, results of
operations or cash flows, or your investment in the debt securities,  could be
materially adversely affected.

THERE CAN BE NO ASSURANCE AS TO THE LIQUIDITY OF THE TRADING MARKET FOR THE
DEBT SECURITIES OR THAT A TRADING MARKET FOR THE DEBT SECURITIES WILL DEVELOP.

     There is no public market for the debt securities  and, unless  otherwise
specified in the applicable prospectus  supplement,  we do not intend to apply
for listing of the debt  securities on any securities  exchanges.  If the debt
securities are traded after their initial issue,  they may trade at a discount
from their initial offering prices depending on prevailing interest rates, the
market for similar  securities and other factors,  including  general economic
conditions  and our financial  condition.  There can be no assurance as to the
liquidity  of the  trading  market for the debt  securities  or that a trading
market for the debt securities will develop.

CREDIT RATINGS MAY NOT REFLECT ALL RISKS OF AN INVESTMENT IN THE DEBT
SECURITIES AND MAY CHANGE.

     Credit ratings may not reflect all risks associated with an investment in
the debt securities.  Any credit ratings applied to the debt securities are an
assessment  of our  ability  to pay  our  obligations.  Consequently,  real or
anticipated  changes in the credit  ratings will  generally  affect the market
value of the debt securities. The credit ratings, however, may not reflect the
potential  impact of risks  related  to  structure,  market  or other  factors
discussed  herein on the value of the debt  securities.  There is no assurance
that any credit rating  assigned to the debt  securities will remain in effect
for any  given  period  of time or that  any  rating  will not be  lowered  or
withdrawn entirely by the relevant rating agency.

CHANGES IN INTEREST RATES MAY CAUSE THE VALUE OF THE DEBT SECURITIES TO
DECLINE.

     Prevailing  interest  rates will affect the market  price or value of the
debt securities.  The market price or value of the debt securities may decline
as  prevailing  interest  rates for  comparable  debt  instruments  rise,  and
increase as prevailing interest rates for comparable debt instruments decline.

THE GUARANTEE WILL BE EFFECTIVELY SUBORDINATED TO CERTAIN INDEBTEDNESS OF
ENCANA'S CORPORATE AND PARTNERSHIP SUBSIDIARIES.

     Unless otherwise indicated in an applicable  prospectus  supplement,  the
debt securities will be our unsecured and unsubordinated  obligations and will
rank equally with all of our other unsecured and  unsubordinated  indebtedness
outstanding  from time to time.  We have no  significant  assets or operations
other than the debt owed to us by the U.S. Group. We are dependent on interest
payments  from the U.S.  Group under the terms of the debt.  Accordingly,  our
ability to make  payments on the debt  securities  will be dependent  upon the
U.S. Group making its payments on its debt to us.

     The  guarantee  will  be the  Guarantor's  unsubordinated  and  unsecured
obligation  and,  unless  otherwise  provided with respect to a series of debt
securities,  will rank equally with all of the  Guarantor's  other  unsecured,
unsubordinated  obligations.  The Guarantor conducts a substantial  portion of
its business through corporate and partnership  subsidiaries.  The Guarantor's
obligations  under  the  guarantee  will be  structurally  subordinate  to all
existing and future indebtedness and liabilities, including trade payables, of
any of the Guarantor's corporate and partnership subsidiaries.

                                      23


                       CERTAIN INCOME TAX CONSIDERATIONS

     The  applicable  prospectus  supplement  will describe  certain  Canadian
federal  income  tax  consequences  to  an  investor  of  acquiring  any  debt
securities offered thereunder,  including, for investors who are non-residents
of Canada,  whether the payments of principal  and  interest,  if any, will be
subject to Canadian non-resident withholding tax.

     The  applicable  prospectus  supplement  will also describe  certain U.S.
federal income tax consequences of the acquisition,  ownership and disposition
of any debt securities offered thereunder by an initial investor who is a U.S.
person (within the meaning of the U.S. Internal Revenue Code),  including,  to
the extent  applicable,  any such  consequences  relating  to debt  securities
payable in a currency other than the U.S. dollar,  issued at an original issue
discount for U.S.  federal income tax purposes or containing  early redemption
provisions or other special items.

                             PLAN OF DISTRIBUTION

     We may offer and sell  debt  securities  to or  through  underwriters  or
dealers and also may sell debt  securities  directly to  purchasers or through
agents.  These debt  securities may be offered and sold in Canada,  the United
States and elsewhere where permitted by law.

     The  distribution  of debt  securities of any series may be effected from
time to time in one or more transactions:

     o     at a fixed price or prices, which may be changed;

     o     at market prices prevailing at the time of sale; or

     o     at prices related to such prevailing market prices to be negotiated
           with purchasers.

     In connection with the sale of debt securities,  underwriters may receive
compensation  from us or from  purchasers of debt securities for whom they may
act as agents in the form of concessions or commissions. Underwriters, dealers
and agents that  participate  in the  distribution  of debt  securities may be
deemed to be underwriters and any commissions received by them from us and any
profit  on  the  resale  of  debt  securities  by  them  may be  deemed  to be
underwriting  commissions  under the United States  Securities Act of 1933, as
amended (the "Securities Act").

     The prospectus supplement relating to each series of debt securities will
also set forth the terms of the offering of the debt securities,  including to
the extent  applicable,  the initial  offering  price,  our proceeds  from the
offering, the underwriting concessions or commissions, and any other discounts
or  concessions  to be allowed or  reallowed  to  dealers.  Underwriters  with
respect to each  series sold to or through  underwriters  will be named in the
prospectus supplement relating to such series.

     Under  agreements  which  may be  entered  into by us and the  Guarantor,
underwriters,  dealers and agents who participate in the  distribution of debt
securities may be entitled to  indemnification  by us or the Guarantor against
certain  liabilities,  including  liabilities  under the  Securities  Act. The
underwriters,  dealers  and agents with whom we and the  Guarantor  enter into
agreements  may be  customers  of,  engage  in  transactions  with or  perform
services for us or the Guarantor in the ordinary course of business.

     Each series of debt  securities will be a new issue of securities with no
established  trading  market.  Unless  otherwise  specified  in  a  prospectus
supplement  relating to a series of debt securities,  the debt securities will
not be listed on any securities  exchange or on any automated dealer quotation
system. Certain  broker-dealers may make a market in the debt securities,  but
will not be obligated to do so and may  discontinue  any market  making at any
time without notice. We cannot assure you that any  broker-dealer  will make a
market in the debt  securities  of any  series or as to the  liquidity  of the
trading market, if any, for the debt securities of any series.

                               INTEREST COVERAGE

     The  following  sets  forth  interest  coverage  ratios of the  Guarantor
calculated  for the twelve  month  period  ended  December  31,  2005 based on
audited financial  information and March 31, 2006 based on unaudited financial
information.

                                      24


The interest  coverage ratios set out below have been prepared and included in
this prospectus in accordance with Canadian  disclosure  requirements and have
been  calculated  based on  information  prepared in accordance  with Canadian
GAAP.  The  interest  coverage  ratios  set out  below  do not  purport  to be
indicative of interest  coverage ratios for any future  periods.  The interest
coverage  ratios do not give  effect to the debt  securities  offered  by this
prospectus  since the aggregate  principal amount of debt securities that will
be issued hereunder and the terms of issue are not presently known.

                                         DECEMBER 31, 2005      MARCH 31, 2006
                                         -----------------      --------------
Interest coverage on long-term debt:
  Net earnings.........................      13.0 times           19.2 times
  Cash flow............................      20.9 times           22.3 times


     Interest  coverage on long-term  debt on a net earnings basis is equal to
net earnings  before  interest on long-term  debt and income taxes  divided by
interest expense on long-term debt.  Interest  coverage on long-term debt on a
cash flow basis is equal to cash flow  before  interest  expense on  long-term
debt and cash income taxes divided by interest  expense on long-term debt. For
purposes  of  calculating  the  interest  coverage  ratios  set forth  herein,
long-term debt includes the current portion of long-term debt.

                                 LEGAL MATTERS

     Unless  otherwise  specified in the prospectus  supplement  relating to a
series of debt securities, certain legal matters relating to Canadian law will
be  passed  upon for us and the  Guarantor  by  Macleod  Dixon  LLP,  Calgary,
Alberta,  Canada.  Certain  legal  matters  in  connection  with the  offering
relating to United  States law will be passed upon for us and the Guarantor by
Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York, New York. In addition,
certain  legal  matters  relating to United States law will be passed upon for
any  underwriters,  dealers or agents by  Shearman &  Sterling  LLP,  Toronto,
Ontario, Canada and New York, New York.

     The  partners  and  associates  of  Macleod  Dixon LLP and  Paul,  Weiss,
Rifkind,  Wharton & Garrison  LLP as a group  beneficially  own,  directly  or
indirectly, less than 1% of any class of the Guarantor's securities.

INDEMNIFICATION

ENCANA CORPORATION


     Under  the  CANADA  BUSINESS   CORPORATIONS  ACT  (the  "CBCA"),   EnCana
Corporation  ("EnCana") may indemnify a present or former  director or officer
of EnCana or another  individual  who acts or acted at  EnCana's  request as a
director or officer, or an individual acting in a similar capacity, of another
entity,  against all costs, charges and expenses,  including an amount paid to
settle an action or satisfy a judgment,  reasonably incurred by the individual
in respect  of any civil,  criminal,  administrative,  investigative  or other
proceeding  in which the  individual is involved  because of that  association
with EnCana or other entity. EnCana may not indemnify an individual unless the
individual  acted honestly and in good faith with a view to the best interests
of EnCana,  or, as the case may be, to the best  interests of the other entity
for  which the  individual  acted as a  director  or  officer  or in a similar
capacity at EnCana's  request and in the case of a criminal or  administrative
action or proceeding  that is enforced by a monetary  penalty,  the individual
had  reasonable  grounds  for  believing  that the  conduct  was  lawful.  The
indemnification  may be made in connection with a derivative  action only with
court approval. The aforementioned individuals are entitled to indemnification
from EnCana as a matter of right if they were not judged by the court or other
competent authority to have committed any fault or omitted to do anything that
the individual ought to have done. EnCana may advance moneys to the individual
for the costs,  charges and expenses of a proceeding;  however, the individual
shall repay the moneys if the  individual  does not fulfill the conditions set
out above.

     The by-laws of EnCana provide that, subject to the limitations  contained
in the CBCA,  EnCana shall indemnify a director or officer,  a former director
or officer, or a person who acts or acted at EnCana's request as a director or
officer  of a body  corporate  of  which  EnCana  is or was a  shareholder  or
creditor,  and his heirs and legal representatives  against all costs, charges
and  expenses,  including  an amount  paid to  settle  an action or  satisfy a
judgment,  reasonably  incurred  by him in respect of any civil,  criminal  or
administrative  action or proceeding to which he was made a party by reason of
being or having  been a director  or officer of the  corporation  or such body
corporate,  if he acted  honestly  and in good  faith  with a view to the best
interests of the corporation,  and in the case of a criminal or administrative
action or proceeding that is enforced by a monetary penalty, he had reasonable
grounds for believing that his conduct was lawful.

     The by-laws of EnCana provide that EnCana may, subject to the limitations
contained in the CBCA, purchase, maintain, or participate in insurance for the
benefit of any director,  officer,  or certain other persons,  as such against
any  liability  incurred  by him in his  capacity  as a director or officer of
EnCana or as a  director  or officer  of any body  corporate  where he acts or
acted in that capacity at EnCana's  request.  EnCana has purchased third party
director and officer liability insurance.

     Insofar as indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted  to  directors,  officers or persons  controlling
EnCana pursuant to the foregoing provisions,  EnCana has been informed that in
the opinion of the Securities and Exchange Commission such  indemnification is
against  public  policy  as  expressed  in the  Securities  Act of 1933 and is
therefore unenforceable.

                                     II-1


ENCANA HOLDINGS FINANCE CORP.

     Under  applicable  Canadian law, EnCana Holdings  Finance Corp.  ("EnCana
Holdings  Finance") is permitted  to indemnify  its officers and  directors on
terms  acceptable to its  shareholders.  The Articles of Association of EnCana
Holdings  Finance  provide  that no director or  officer,  former  director or
officer,  or person who acts or acted at EnCana Holdings Finance request, as a
director or officer of EnCana Holdings Finance, a body corporate,  partnership
or other association of which EnCana Holdings Finance is or was a shareholder,
partner, member or creditor, in the absence of any dishonesty on such person's
part,  shall be liable for the acts,  receipts,  neglects  or  defaults of any
other director, officer or such person, or for joining in any receipt or other
act for  conformity,  or for any loss,  damage or  expense  of any kind  which
happens in the execution of the duties of such person or in relation thereto.

     The Articles of Association of EnCana Holdings  Finance also provide that
every director or officer,  former director or officer,  or person who acts or
acted at EnCana Holdings Finance's request, as a director or officer of EnCana
Holdings Finance, a body corporate,  partnership or other association of which
EnCana Holdings Finance is or was a shareholder,  partner, member or creditor,
and the heirs and legal  representatives of such person, in the absence of any
dishonesty on the part of such person, shall be indemnified by EnCana Holdings
Finance against, and it shall be the duty of the directors out of the funds of
EnCana Holdings Finance to pay, all costs,  losses and expenses,  including an
amount  paid to settle an action  or claim or  satisfy a  judgment,  that such
director,  officer or person  may incur or become  liable to pay in respect of
any claim made against such person or civil, criminal or administrative action
or  proceeding  to which  such  person  is made a party by  reason of being or
having  been a director  or officer  of EnCana  Holdings  Finance or such body
corporate,  partnership or other association,  whether EnCana Holdings Finance
is a claimant  or party to such action or  proceeding  or  otherwise;  and the
amount for which such indemnity is proved shall  immediately  attach as a lien
on the property of EnCana  Holdings  Finance and have  priority as against the
shareholders over all other claims.

     As a subsidiary of EnCana,  EnCana  Holdings  Finance is insured  against
liabilities  which it may incur by reason of the  foregoing  provisions of its
Articles of Association and directors and officers of EnCana Holdings  Finance
are insured against some liabilities which might arise out of their employment
and  not be  subject  to the  indemnification  contained  in the  Articles  of
Association of EnCana Holdings Finance as previously described.

     Insofar as indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted  to  directors,  officers or persons  controlling
EnCana Holdings Finance pursuant to the foregoing provisions,  EnCana Holdings
Finance has been informed that in the opinion of the  Securities  and Exchange
Commission such  indemnification  is against public policy as expressed in the
Securities Act of 1933 and is therefore unenforceable.
