                             ABOUT THIS PROSPECTUS

     In this prospectus,  unless otherwise  specified or the context  otherwise
indicates,  references to "Canadian Natural", "us", "we" or "our" mean Canadian
Natural  Resources  Limited  and  its  subsidiaries,   including  its  material
operating  subsidiaries  and, where applicable,  their respective  interests in
partnerships and other entities. Unless otherwise specified, all dollar amounts
contained in this prospectus are expressed in Canadian dollars,  and references
to "dollars", "Cdn$" or "$" are to Canadian dollars and all references to "US$"
are to United States dollars.

     All financial  information  included and incorporated by reference in this
prospectus is determined using generally accepted  accounting  principles which
are in effect  from time to time in Canada,  referred  to as  "Canadian  GAAP".
"U.S. GAAP" means generally accepted accounting  principles which are in effect
from time to time in the United States.

     This  prospectus  replaces our amended and restated base shelf  prospectus
dated November 27, 2006.

     This  prospectus is part of a registration  statement on Form F-9 relating
to the debt  securities  that we filed with the U.S.  Securities  and  Exchange
Commission (the "SEC").  Under the shelf registration  statement,  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$3,000,000,000.  This prospectus  provides you with a general  description of
the debt securities that we may offer.  Each time we sell debt securities under
the registration  statement,  we will provide a prospectus supplement that will
contain  specific  information  about  the  terms  of  that  offering  of  debt
securities.   The  prospectus   supplement  may  also  add,  update  or  change
information  contained in this prospectus.  Before you invest,  you should read
both this  prospectus and any applicable  prospectus  supplement  together with
additional  information  described  under the heading  "Where You Can Find More
Information". This prospectus does not contain all of the information set forth
in the registration statement, certain parts of which are omitted in accordance
with the rules and  regulations  of the SEC. You may refer to the  registration
statement  and  the  exhibits  to  the   registration   statement  for  further
information with respect to us and the debt securities.

                                  DEFINITIONS

     In this prospectus and in any applicable prospectus supplement:

     o   "Boe" means barrels of oil equivalent.

     This  prospectus  contains  disclosure  respecting  oil and gas production
expressed  as "cubic  feet of  natural  gas  equivalent"  and  "barrels  of oil
equivalent" or "boe". All equivalency volumes have been derived using the ratio
of six  thousand  cubic feet of natural  gas to one barrel of oil.  Equivalency
measures may be  misleading,  particularly  if used in isolation.  A conversion
ratio of six  thousand  cubic feet of natural gas to one barrel of oil is based
on an energy equivalence  conversion method primarily  applicable at the burner
tip and does not represent a value equivalency at the wellhead.


                      WHERE YOU CAN FIND MORE INFORMATION

     We file with the Alberta  Securities  Commission (the "ASC"), a commission
of authority in the Province of Alberta  similar to the SEC,  material  change,
annual and  quarterly  reports  and other  information.  We are  subject to the
informational  requirements  of the U.S.  Securities  Exchange Act of 1934,  as
amended (the "Exchange Act"), and, in accordance with the Exchange Act, we file
reports   and   furnish   other   information   with   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 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 by paying a fee. The SEC also  maintains an internet
site that contains  reports and other  information  about issuers like us, that
file electronically with the SEC. The site address is www.sec.gov.

     Under the  multijurisdictional  disclosure  system  adopted  by the United
States  and  the  provinces  of  Canada,  the  SEC  and  the  ASC  allow  us to
"incorporate by reference"  certain  information we file 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 ASC under the SECURITIES ACT (Alberta):

     o   our Annual  Information  Form dated  March 28,  2007 and  management's
         discussion  and  analysis  of  financial   condition  and  results  of
         operations  for the year  ended  December  31,  2006  incorporated  by
         reference in the Annual Information Form;

     o   our  Information  Circular dated March 14, 2007 relating to the Annual

         portions thereof which appear under the headings  "Performance Graph",
         "Report on Executive  Compensation by the Compensation  Committee" and
         "Statement of Corporate Governance Practices" (which portions shall be
         deemed not to be incorporated by reference in this prospectus);

     o   our audited comparative  consolidated  financial  statements as at and
         for the year ended  December 31,  2006,  together  with the  auditors'
         report thereon; and

     o   our unaudited  comparative  consolidated  financial statements for the
         six month  period  ended June 30, 2007 and  accompanying  management's
         discussion and analysis.

     Any  documents  of the type  referred to in the  preceding  paragraph,  or
similar  material,  including  an  Annual  Information  Form  filed by us,  all

                         DESCRIPTION OF DEBT SECURITIES

     In this section,  "we", "us",  "our" or "Canadian  Natural" refers only to
Canadian  Natural  Resources  Limited  without its  subsidiaries or interest in
partnerships and other entities.  The following describes certain general terms
and provisions of the debt  securities.  The particular terms and provisions of
the series of debt  securities  offered by any prospectus  supplement,  and the
extent to which the general terms and provisions  described  below may apply to
them, will be described in the applicable prospectus  supplement.  Accordingly,
for a  description  of the terms of a  particular  series  of debt  securities,
reference must be made to both the applicable prospectus supplement relating to
them and the description of the debt securities set forth in this prospectus.

     The  debt   securities  will  be  issued  under  a  trust  indenture  (the
"Indenture")  dated July 24, 2001  between us and The Bank of Nova Scotia Trust
Company of New York,  as trustee (the  "Trustee").  The Indenture is subject to
and governed by the United States Trust  Indenture  Act of 1939, as amended.  A
copy of the form of the  Indenture has been filed with the SEC as an exhibit to
the  registration  statement of which this  prospectus is a part. The following
summaries  of the  Indenture  and the debt  securities  are brief  summaries of
certain  provisions of the  Indenture and do not purport to be complete;  these
statements are subject to the detailed referenced  provisions of the Indenture,
including the definition of capitalized terms used under this caption. Wherever
particular  sections or defined  terms of the  Indenture are referred to, these
sections or defined terms are  incorporated  in this prospectus by reference as
part of the statement  made,  and the statement is qualified in its entirety by
the  reference  to the  Indenture.  References  in  parentheses  are to section
numbers in the Indenture.

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 may be issued under the Indenture, and provides that debt
securities  may be issued  from time to time in one or more  series  and may be
denominated  and payable in foreign  currencies.  The debt  securities  offered
pursuant to this prospectus will be issued in an amount up to  US$3,000,000,000
or the  equivalent.  The  Indenture  also permits us to increase the  principal
amount of any  series of debt  securities  previously  issued and to issue that
increased principal amount.

         and/or the method by which such date or dates shall be determined;

         option to redeem the debt  securities  of such series  rather than pay
         the Additional Amounts (and the terms of any such option);

     (n) any  deletions  from,  modifications  of or additions to the Events of

         consistent  with the Events of Default or covenants  set forth herein;
         and

     (o) any other terms of the debt securities of such series.

     Unless otherwise indicated in the applicable  prospectus  supplement,  the
Indenture does not afford the Holders the right to tender debt securities to us
for  repurchase,  or provide for any  increase in the rate or rates of interest
per annum at which the debt  securities  will  bear  interest,  in the event we
become  involved  in a highly  leveraged  transaction  or in the event  that we
undergo a change in control.

     Debt  securities may be issued under the Indenture  bearing no interest or
interest at a rate below the prevailing market rate at the time of issuance and
may be offered and sold at a discount below their stated principal amount.  The
Canadian  and  U.S.   federal  income  tax   consequences   and  other  special
considerations  applicable to those  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.

RANKING AND OTHER INDEBTEDNESS

     The debt  securities  will be unsecured  obligations  of ours and,  unless
otherwise  provided  in  the  prospectus   supplement  relating  to  such  debt
securities,   will  rank  PARI   PASSU  with  all  our  other   unsecured   and
unsubordinated  debt from time to time  outstanding  and PARI  PASSU with other
debt  securities  issued  under  the  Indenture.  The debt  securities  will be

                                       8


structurally  subordinated to all existing and future liabilities of any of our
corporate  or  partnership  subsidiaries,  including  trade  payables and other
indebtedness.

REGISTERED GLOBAL SECURITIES

     Unless otherwise  indicated in a prospectus  supplement,  a series of debt
securities  will  be  issued  in the  form  of one or  more  Registered  Global
Securities  which will be  registered  in the name of and be  deposited  with a
Depository,  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 debt securities in definitive  registered  form, a Registered  Global
Security  may not be  transferred  except  as a whole by the  Depository  for a
Registered  Global  Security to a nominee of that  Depository,  by a nominee of
that  Depository to that Depository or another nominee of that Depository or by
that  Depository  or any  nominee of that  Depository  to a  successor  of that
Depository or a nominee of a successor of that Depository.

     The  specific  terms of the  depository  arrangement  with  respect to any
portion  of a  particular  series of debt  securities  to be  represented  by a
Registered  Global  Security  will be  described in the  prospectus  supplement
relating  to that  series.  Canadian  Natural  anticipates  that the  following
provisions will apply to all depository arrangements.

     Upon the issuance of a Registered  Global Security,  the Depository or its
nominee will credit, on its book entry and registration  system, the respective
principal amounts of the debt securities  represented by that Registered Global
Security to the accounts of those persons having  accounts with that Depository
or its nominee  ("participants")  as shall be designated  by the  underwriters,
investment  dealers or agents  participating  in the distribution of those debt
securities or by us if those debt  securities  are offered and sold directly by
us. Ownership of beneficial  interests in a Registered  Global Security will be
limited to participants or persons that may hold beneficial  interests  through
participants. Ownership of beneficial interests in a Registered Global Security
will be shown  on,  and the  transfer  of the  ownership  of  those  beneficial
interests will be effected only through,  records  maintained by the Depository
therefor or its nominee (with respect to beneficial  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 require certain purchasers of
securities to take physical delivery of the debt securities in definitive form.
These depository arrangements and these laws may impair the ability to transfer
beneficial interests in a Registered Global Security.

     So long as the Depository for a Registered  Global Security or its nominee
is the registered owner of the debt securities, that Depository or its nominee,
as the case may be,  will be  considered  the sole  owner or Holder of the debt
securities  represented  by that  Registered  Global  Security for all purposes
under the Indenture.  Except as provided below, owners of beneficial  interests
in a Registered Global Security will not be entitled to have debt securities of
the series  represented by that Registered Global Security  registered in their
names,  will not receive or be entitled  to receive  physical  delivery of debt
securities  of that series in definitive  form and will not be  considered  the
owners or Holders of those debt securities under the Indenture.

     Principal,  premium,  if any, and interest payments on a Registered Global
Security  registered in the name of a Depository or its nominee will be made to
that Depository or nominee, as the case may be, as the registered owner of that
Registered  Global  Security.  Neither we, the Trustee nor any paying agent for
debt securities of the series  represented by that  Registered  Global Security
will  have any  responsibility  or  liability  for any  aspect  of the  records
relating  to or  payments  made on  account  of  beneficial  interests  in that
Registered  Global  Security or for  maintaining,  supervising or reviewing any
records relating to those beneficial interests.

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

                                       9


     If the  Depository  for a Registered  Global  Security  representing  debt
securities  of a  particular  series  is at any time  unwilling  or  unable  to
continue as Depository,  or if the Depository is no longer eligible to continue
as  Depository,  and a successor  Depository  is not  appointed by us within 90
days,  or if an Event of Default  described  in clauses (a) or (b) of the first
sentence under "Events of Default" below with respect to a particular series of
debt  securities  has  occurred  and is  continuing,  we will issue  Registered
Securities  of that series in definitive  form in exchange for that  Registered
Global  Security.  In addition,  we may at any time and in its sole  discretion
determine not to have the debt securities of a particular series represented by
one or more  Registered  Global  Securities  and,  in that  event,  will  issue
Registered  Securities of that series in definitive form in exchange for all of
the Registered Global Securities representing debt securities of that series.

DEBT SECURITIES IN DEFINITIVE FORM

     If indicated in an applicable prospectus  supplement,  the debt securities
may be issued in definitive form without coupons. Debt securities in definitive
form may be  presented  for exchange  and for  registration  of transfer in the
manner,  at the  places  and,  subject  to the  restrictions  set  forth in the
Indenture and in the applicable prospectus supplement,  without service charge,
but upon payment of any taxes or other  governmental  charges due in connection
therewith. We have appointed the Trustee as Security Registrar. Debt securities
in  bearer  form  and  the  coupons  appertaining  thereto,  if  any,  will  be
transferable by delivery.

     Unless  otherwise  indicated  in  the  applicable  prospectus  supplement,
payment of the principal of and any premium and interest on debt  securities in
definitive  form will be made at the  office or  agency of the  Trustee  at One
Liberty Plaza, New York, New York 10006, except that, at our option, payment of
any  interest  may be made (a) by check  mailed to the  address  of the  Person
entitled thereto as that Person's address will appear in the Security  Register
or (b) by wire transfer to an account maintained by the Person entitled thereto
as specified in the Security Register.

NEGATIVE PLEDGE

     The  Indenture  includes  our  covenant  that,  so long as any of the debt
securities remain outstanding,  we will not, and will not permit any Subsidiary
to, create, assume or otherwise have outstanding any Security Interest,  except
for Permitted Encumbrances,  on or over its or their respective assets (present
or future)  securing any  Indebtedness  of any Person  without also at the same
time or prior to that time securing equally and ratably with other Indebtedness
all of the debt securities then Outstanding under the Indenture.

         at the time by  Canadian  Natural  or a  Subsidiary  in good  faith or
         payment of which has been  provided for by deposit with the Trustee of
         an  amount  in cash  sufficient  to pay the same in full,  (viii)  any
         easements, rights-of-way and servitudes (including, without in any way
         limiting the generality of the foregoing, easements, rights-of-way and

         arising  out of  judgments  or awards with  respect to which  Canadian
         Natural  or  the   Subsidiary   shall  be  prosecuting  an  appeal  or
         proceedings for review and with respect to which it shall have secured
         a stay of execution pending such appeal or proceedings for review;

         becomes  due under any  provision  of the  Indenture  or of those debt
         securities;

                                      14

         greater of $75  million and 2 percent of the  Shareholders'  Equity of
         Canadian Natural in the aggregate at the time of default or default in
         the  performance  of any other  covenant  of  Canadian  Natural or any
         Subsidiary  contained in any instrument under which that  indebtedness
         is created or issued and the holders  thereof,  or a trustee,  if any,
         for those  holders,  declare that  indebtedness  to be due and payable
         prior to the  stated  maturities  of that  indebtedness  ("accelerated
         indebtedness"),  and  such  acceleration  shall  not be  rescinded  or
         annulled,  or such default under such instrument shall not be remedied
         or cured, whether by payment or otherwise, or waived by the holders of
         such indebtedness,  provided that if such accelerated  indebtedness is

         conditions set forth in such instrument,  it will not be considered an
         Event of  Default  under  this  clause  (e) until 15 days  after  such
         acceleration;

         discharged or stayed as provided in the Indenture; or

     If an Event of Default  described in clause (a) or (b) above occurs and is
continuing with respect to debt securities of any series,  unless the principal
of all of the debt  securities of that series shall have already become due and
payable, the Trustee may, in its discretion,  and shall upon request in writing
made by the Holders of not less than 25 percent in aggregate  principal  amount
of the debt securities of that series then  Outstanding,  declare the principal
of (and  premium,  if any,  on) all the debt  securities  of that  series  then
Outstanding and the interest accrued thereon and all other money, if any, owing
under the provisions of the Indenture in respect of those debt securities to be
due and payable  immediately  on demand.  If an Event of Default  described  in
clause  (d) or (h) above  occurs  and is  continuing  with  respect to the debt
securities  of one or more  series,  unless  the  principal  of all of the debt
securities  of the affected  series shall have already  become due and payable,

the Holders of not less than 25 percent in  aggregate  principal  amount of the
debt  securities of all such affected  series then  Outstanding  (voting as one
class),  declare  the  principal  of (and  premium,  if any,  on) all the  debt
securities of all the affected series then Outstanding and the interest accrued
thereon  and all  other  money,  if any,  owing  under  the  provisions  of the
Indenture in respect of those debt securities to be due and payable immediately
on demand.  If an Event of Default  described  in clause (c),  (e),  (f) or (g)
above occurs and is  continuing,  unless the  principal of all debt  securities
then Outstanding shall have already become due and payable, the Trustee may, in
its  discretion,  and shall upon  request in writing made by the Holders of not
less than 25 percent in aggregate  principal  amount of all the debt securities
then Outstanding (voting as one class),  declare the principal of (and premium,
if any, on) all the debt securities then  Outstanding and the interest  accrued
thereon  and all  other  money,  if any,  owing  under  the  provisions  of the
Indenture in respect of those debt securities to be due and payable immediately
on demand.

                                      15


     Upon certain conditions,  any declaration of this kind may be cancelled if
all Events of Default with respect to the debt securities of all those affected
series  then  Outstanding  shall have been cured or waived as  provided  in the
Indenture  by the  Holders of not less than a majority in  aggregate  principal
amount of the debt securities of the affected series then  Outstanding  (voting
as one class,  except in the case of Events of Default described in clauses (a)
and (b) of the first  sentence  of the  preceding  paragraph,  as to which each
series so  affected  will vote as a  separate  class).  See  "Modification  and
Waiver"  below.  Reference is made to the applicable  prospectus  supplement or
supplements  relating to any series of Original Issue  Discount  Securities for
the  particular  provisions  relating to the  acceleration  of a portion of the
principal  amount thereof upon the  occurrence  and  continuance of an Event of
Default with respect thereto.

     The  Indenture  provides  that the Trustee will be under no  obligation to
exercise  any of its rights or powers  under the  Indenture  at the  request or
direction  of the  Holders,  unless those  Holders  shall have  provided to the
Trustee  reasonable  indemnity.  Subject to those  provisions for indemnity and
certain other limitations contained in the Indenture, the Holders of a majority
in aggregate  principal  amount of the debt  securities of all affected  series
then Outstanding  (voting as one class) will 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 those affected series.

     The Indenture provides that no Holder of the debt securities of any series
will have any right to institute any  proceeding  with respect to the Indenture
or for any remedy  thereunder,  unless (a) that  Holder  shall have  previously
given to the  Trustee  written  notice of a  continuing  Event of Default  with
respect to the debt securities of that series, (b) the Holders of not less than
25 percent in aggregate principal amount of the debt securities of all affected
series then Outstanding  (voting as one class) shall have made written request,
and provided reasonable indemnity, to the Trustee to institute that proceeding,
(c) the Trustee shall have failed to institute that  proceeding  within 60 days
after that  notification,  request and offer of  indemnity  and (d) the Trustee
shall not have received  from the Holders of a majority in aggregate  principal
amount of the debt securities of all affected series then  Outstanding  (voting
as one class) a direction  inconsistent  with that  request  during such 60 day
period.  However,  the Holder of any  Security  will have an absolute  right to
receive  payment of the  principal  of and any  premium  and  interest  on that
Security on or after the due dates  expressed in that Security and to institute
suit for the  enforcement  of any of these  payments.  The  Indenture  requires
Canadian Natural to furnish to the Trustee annually an Officers' Certificate as
to the  compliance by Canadian  Natural with certain  covenants,  conditions or
other  requirements  contained in the  Indenture  and as to any  non-compliance
therewith.

     The Indenture provides that the Trustee may withhold notice to the Holders
of the debt  securities  of one or more series of any default  affecting  those
series (except  defaults as to payment of principal or interest) if it, in good
faith, considers that withholding to be in the best interests of the Holders of
the debt securities of those series.

CONSOLIDATION, MERGER, AMALGAMATION AND SALE OF ASSETS

     Canadian  Natural shall not enter into any transaction  (whether by way of
reorganization,  reconstruction,  consolidation,  amalgamation,  merger, lease,
transfer,  sale or otherwise)  whereby all or  substantially  all of its assets
would  become the property of any other  Person (the  "Successor  Corporation")
unless (a) the Successor Corporation shall, prior to or contemporaneously  with
the  consummation of that  transaction,  execute those  instruments,  which may
include a supplemental indenture,  and do those things as shall be necessary or
advisable to establish that upon the  consummation of that  transaction (i) the
Successor Corporation will have assumed all of the covenants and obligations of
Canadian Natural under the Indenture in respect of the debt securities of every
series,  and (ii) the debt securities of every series will be valid and binding
obligations  of the Successor  Corporation  entitling the Holders  thereof,  as
against  the  Successor  Corporation,  to all the  rights  of  Holders  of debt
securities under the Indenture; (b) the Successor Corporation is a corporation,
partnership,  or trust organized and validly  existing under the laws of Canada
or any  province  thereof or of the  United  States,  any state  thereof or the
District of Columbia, (c) Canadian Natural has delivered to the Trustee, within
60 days  thereof,  an  Officer's  Certificate  and an Opinion  of Counsel  each
stating that such transaction and such supplemental  indenture comply with this
covenant  and  all  conditions  precedent  to  Section  7.1  relating  to  such
transaction  have been  complied  with,  and (d)  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 occurred and be continuing.

                                      16


ADDITIONAL AMOUNTS

     Unless otherwise specified in the applicable  prospectus  supplement,  all
payments made by Canadian  Natural under or with respect to the debt securities
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 of any province or territory  thereof or by any authority or agency  therein
or thereof having power to tax (hereinafter "Canadian Taxes"),  unless Canadian
Natural is  required  to  withhold  or deduct  Canadian  Taxes by law or by the
interpretation or administration thereof. If Canadian Natural is 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,  Canadian  Natural
will  pay to  each  Holder  as  additional  interest  such  additional  amounts
("Additional  Amounts") as may be necessary so that the net amount  received by
each Holder  after such  withholding  or  deduction  (and after  deducting  any
Canadian Taxes on such Additional Amounts) will not be less than the amount the
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 Holder (such Holder, an "Excluded  Holder") in respect of the
beneficial owner thereof:

     (a) with which Canadian  Natural does not deal at arm's length (within the
         meaning  of the INCOME TAX ACT  (Canada))  at the time of making  such
         payment;

     (b) which is subject to such Canadian  Taxes by reason of the 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  debt
         securities or the receipt of payments thereunder; or

     (c) which is  subject  to such  Canadian  Taxes by reason of the  Holder's
         failure to comply with any certification, identification, information,
         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.

     Canadian Natural will also:

     (a) make such withholding or deduction; and

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

     Canadian  Natural  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 Canadian Natural.

     Canadian  Natural will indemnify and hold harmless each Holder (other than
an Excluded Holder) and upon written request reimburse each such Holder for the
amount of:

     (a) any  Canadian  Taxes so levied or imposed and paid by such Holder as a
         result of payments made under or with respect to the debt securities;

     (b) any liability  (including  penalties,  interest and expenses)  arising
         therefrom or with respect thereto; and

     (c) any Canadian  Taxes  imposed with respect to any  reimbursement  under
         clause (i) or (ii) above,  but excluding  any such  Canadian  Taxes on
         such Holder's net income.

                                      17


     Wherever in the Indenture there is mentioned,  in any context, the payment
of principal (and premium,  if any), interest or any other amount payable under
or with respect to a Security,  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

     The debt  securities  will be subject to redemption  in whole,  but not in
part, at the option of Canadian  Natural,  at any time, on not less than 30 nor
more than 60 days prior written notice, at 100 percent of the principal amount,
together with accrued  interest  thereon to the  redemption  date, in the event
that we have become or would become obligated to pay, on the next date on which
any amount would be payable with respect to the debt securities, any Additional
Amounts as a result of an  amendment  to or change in the laws  (including  any
regulations  promulgated thereunder) of Canada (or any political subdivision or
taxing  authority  thereof or  therein),  or any  amendment to or change in any
official  position  regarding the application or interpretation of such laws or
regulations,  which change is  announced  or becomes  effective on or after the
date of this prospectus.

MODIFICATION AND WAIVER

     The  Indenture  permits  Canadian  Natural  and the  Trustee to enter into
supplemental  indentures  without  the  consent  of the  Holders  of  the  debt
securities  to, among other  things:  (a) secure the debt  securities of one or
more series,  (b) evidence  the  assumption  by the  Successor  Corporation  of
Canadian  Natural's  covenants and obligations under the Indenture and the debt
securities  then  Outstanding,  (c) add  covenants or Events of Default for the
benefit of the Holders of one or more series of the debt  securities,  (d) cure
any ambiguity or correct or supplement any defective provision in the Indenture
which correction will not be prejudicial to the interests of the Holders of the
debt securities, (e) establish the form and terms of the debt securities of any
series, (f) evidence the acceptance of appointment by a successor Trustee,  (g)
to comply with any  requirements of the SEC in order to effect and maintain the
qualification  of the  Indenture  under the  Trust  Indenture  Act of 1939,  as
amended, (h) to supplement any of the provisions of the Indenture to the extent
necessary to permit or  facilitate  defeasance  and  discharge of any series of
debt securities,  provided, however, such action shall not adversely affect the
interests of the Holders of any debt  securities in any material  respect,  and
(i) make any other modifications which will not be prejudicial to the interests
of the Holders of the debt securities.

     The  Indenture  also permits  Canadian  Natural and the Trustee,  with the
consent of the Holders of a majority in aggregate  principal amount of the debt
securities of each series then  Outstanding and affected (voting as one class),
to add any  provisions  to,  or change in any  manner or  eliminate  any of the
provisions  of, the Indenture or modify in any manner the rights of the Holders
of the debt securities of each such affected series;  provided,  however,  that
Canadian  Natural  and the Trustee may not,  among  other  things,  without the
consent of the Holder of each Security then  Outstanding and affected  thereby:
(a) change the Stated  Maturity of the principal  amount of, or any installment
of the principal of or the interest on, that Security, (b) reduce the principal
amount of or the rate of interest on or any premium payable upon the redemption
of that  Security,  (c) reduce the amount of  principal  of an  Original  Issue
Discount Security payable upon acceleration of the Maturity thereof, (d) change
the place or currency of payment of the principal of or any premium or interest
on that Security, (e) impair the right to institute suit for the enforcement of
payment  of this kind with  respect  to that  Security  on or after the  Stated
Maturity  thereof,  (f)  reduce  the  percentage  in  principal  amount  of the
Outstanding  Securities of the affected series, the consent of whose Holders is
required for modification or amendment of the Indenture, or for any waiver with
respect  to  defaults,   breaches,   Events  of  Default  or   declarations  of
acceleration,  (g)  change  the  time at  which  any  Security  may or shall be
redeemable or repayable,  (h) change any obligation of Canadian  Natural to pay
additional  amounts  provided  for  pursuant  to the  Indenture,  with  certain
exceptions, or (i) modify any provisions of the Indenture relating to modifying
or amending the Indenture or the waiving of past  defaults or covenants  except
as otherwise specified in the Indenture.

     Prior to the  acceleration  of the  Maturity of any debt  securities,  the
Holders of a majority in aggregate  principal  amount of the debt securities of
all series at the time Outstanding with respect to which a default or breach or
an Event of Default shall have occurred and be continuing (voting as one class)
may on behalf of the Holders of all such  affected  debt  securities  waive any
past  default  or breach or Event of  Default  and its  consequences,  except a
default in the  payment of the  principal  of or  premium  or  interest  on any
Security  of any series or an Event of  Default  in  respect  of a covenant  or
provision  of the  Indenture  or of any  Security  which  cannot be modified or
amended without the consent of the Holder of each Security affected.

                                      18


DEFEASANCE AND COVENANT DEFEASANCE

     Unless otherwise specified in the applicable  prospectus  supplement,  the
Indenture  provides that, at the option of Canadian  Natural,  Canadian Natural
will be  discharged  from  any and all  obligations  with  respect  to the debt
securities  of any series  (except for  certain  obligations  to  register  the
transfer  or  exchange  of the  debt  securities  of that  series,  to  replace
mutilated,  destroyed,  lost or  stolen  debt  securities  of that  series,  to
maintain  paying  agencies,  to  compensate  and  indemnify  the Trustee and to
maintain  the  trust and  payments  under  the  trust  described  below and the
defeasance  provisions of the Indenture)  (hereinafter  called a  "defeasance")
upon the  irrevocable  deposit with the  Trustee,  in trust,  of money,  and/or
Government  Obligations which, through the payment of the principal thereof and
the interest thereon in accordance with their terms,  will provide money, in an
amount  sufficient,   in  the  opinion  of  a  nationally  recognized  firm  of
independent chartered accountants,  to pay all the principal of and any premium
and interest on the debt  securities  of that series on the Stated  Maturity of
those  payments in  accordance  with the terms of the debt  securities  of that
series.  Such a defeasance  may be effected  only if, among other  things,  (i)
Canadian  Natural  has  delivered  to the  Trustee an Opinion of Counsel in the
United States (who may be counsel for Canadian  Natural)  stating that Canadian
Natural has received from, or there has been published by, the Internal Revenue
Service a ruling,  since the date of the Indenture,  or there has been a change
in the applicable  laws or  regulations,  in either case to the effect that the
Holders of the debt securities of that series will not recognize  income,  gain
or loss for  United  States  federal  income tax  purposes  as a result of that
defeasance  and will be subject to United States federal income tax on the same
amounts,  in the same  manner and at the same times as would have been the case
if that defeasance had not occurred, and (ii) Canadian Natural has delivered to
the Trustee an Opinion of Counsel in Canada  (who may be counsel  for  Canadian
Natural)  or a ruling  from the Canada  Revenue  Agency to the effect  that the
Holders of the debt securities of that series will not recognize  income,  gain
or loss for  Canadian  federal  or  provincial  income  or other  Canadian  tax
purposes as a result of that defeasance and will be subject to Canadian federal
or provincial income and other Canadian tax (including  withholding tax) on the
same  amounts,  in the same manner and at the same times as would have been the
case if that defeasance had not occurred (and for the purposes of such opinion,
such Canadian counsel shall assume that Holders of the debt securities  include
holders who are not resident in Canada). In addition, Canadian Natural may also
obtain a discharge of the Indenture with respect to the debt  securities of all
series issued under the Indenture by depositing with the Trustee,  in trust, an
amount of money and  government  securities  as shall be  sufficient to pay, at
Stated Maturity or upon redemption, all of those debt securities, provided that
those debt  securities  are by their terms to become due and payable within one
year or are to be called for redemption within one year.

     The Indenture also provides that Canadian  Natural may omit to comply with
the restrictive  covenants  described under the caption  "Negative  Pledge" and
certain other covenants and no Event of Default shall arise with respect to the
debt securities of that series by reason of this failure to comply (hereinafter
called a "covenant defeasance"), upon the irrevocable deposit with the Trustee,
in trust, of money and/or Government  Obligations which, through the payment of
the principal  thereof and the interest thereon in accordance with their terms,
will provide  money,  in an amount  sufficient,  in the opinion of a nationally
recognized firm of independent chartered accountants,  to pay all the principal
of and any premium and  interest on the debt  securities  of that series on the
Stated  Maturity  of those  payments in  accordance  with the terms of the debt
securities of that series. Canadian Natural's other obligations with respect to
the debt  securities  of that series would  remain in full force and effect.  A
covenant  defeasance may be effected only if, among other things,  (i) Canadian
Natural has delivered to the Trustee an Opinion of Counsel in the United States
(who may be counsel  for  Canadian  Natural)  to the effect that the Holders of
debt  securities  of that series will not  recognize  income,  gain or loss for
United  States  federal  income  tax  purposes  as a  result  of  the  covenant
defeasance  and will be subject to United States federal income tax on the same
amounts,  in the same  manner and at the same times as would have been the case
if that covenant  defeasance  had not occurred,  and (ii) Canadian  Natural has
delivered  to the  Trustee an Opinion of Counsel in Canada  (who may be counsel
for Canadian  Natural) or a ruling from the Canada Revenue Agency to the effect
that the  Holders of the debt  securities  of that  series  will not  recognize
income,  gain or loss  for  Canadian  federal  or  provincial  income  or other
Canadian  tax  purposes  as a result of that  covenant  defeasance  and will be
subject  to  Canadian  federal or  provincial  income  and other  Canadian  tax
(including  withholding tax) on the same amounts, in the same manner and at the
same  times as would  have been the case if that  covenant  defeasance  had not
occurred  (and for the purposes of such opinion,  such  Canadian  counsel shall
assume that Holders of the debt securities include holders who are not resident
in Canada).

     In the  event  that  Canadian  Natural  exercises  its  option to effect a
covenant  defeasance  with respect to the debt securities of any series and the
debt securities of that series are thereafter  declared due and payable because

                                      19


of the  occurrence  of  another  Event of  Default,  the  amount  of money  and
securities on deposit with the Trustee would be sufficient, in the opinion of a
nationally  recognized firm of independent  chartered  accountants,  to pay the
amounts due on the debt  securities of that series at their  respective  Stated
Maturities,  but  may  not  be  sufficient,  in  the  opinion  of a  nationally
recognized firm of independent chartered accountants, to pay the amounts due on
the debt  securities of that series at the time of the  acceleration  resulting
from that Event of Default.  However,  Canadian Natural would remain liable for
this deficiency.

PROVISION OF FINANCIAL INFORMATION

     We will file with the Trustee,  within 15 days after we file them with the
SEC,  copies of our  annual  report  and other  information  (or copies of such
portions  of any of the  foregoing  as the SEC  may by  rules  and  regulations
prescribe) which we are required to file with the SEC pursuant to Section 13 or
15(d) of the  Exchange  Act.  Notwithstanding  that we 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, we will  continue to provide the Trustee,
and file with the SEC, in accordance with rules and regulations prescribed from
time to time by the SEC, the  information,  documents  and reports which may be
required  pursuant to Section 13 of the Exchange  Act, in respect of a security
listed and  registered on a national  securities  exchange as may be prescribed
from  time  to time  in  such  rules  and  regulations,  which,  regardless  of
applicable  requirements  shall,  at a  minimum,  consist  of such  information
required to be  provided  in  quarterly  and annual  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 we have any or
our securities  listed on such exchange.  Such  information will be prepared in
accordance with Canadian disclosure requirements and Canadian GAAP.

RESIGNATION OF TRUSTEE

     The Trustee may resign or be removed with respect to one or more series of
debt securities and a successor Trustee may be appointed to act with respect to
such  series.  In the event that two or more persons are acting as Trustee with
respect to different  series of debt  securities,  each such Trustee shall be a
Trustee  of a trust  under the  Indenture  separate  and  apart  from the trust
administered by any other such Trustee,  and any action  described herein to be
taken by the  "Trustee" may then be taken by each such Trustee with respect to,
and only with respect to, the one or more series of debt  securities  for which
it is Trustee.

PAYMENT AND PAYING AGENTS

     Unless  otherwise  provided  in  the  applicable  prospectus   supplement,
principal,  premium,  if any, and interest,  if any, on debt securities will be
payable  at an office or agency of the  Trustee in New York,  New York,  except
that at our option  interest,  if any,  may be paid (i) by check  mailed to the
address of the Person  entitled  thereto as such  address  shall  appear in the
Security  Register or (ii) by wire transfer to an account located in the United
States  maintained by the Person entitled  thereto as specified in the Security
Register.  Unless otherwise provided in the applicable  prospectus  supplement,
payment of any  instalment of interest on debt  securities  will be made to the
Person in whose name such debt  security is registered at the close of business
on the Regular Record Date for such interest.

     Any Paying Agents outside the United States and any other Paying Agents in
the United States  initially  designated by us for the debt  securities will be
named in the  applicable  prospectus  supplement.  We may at any time designate
additional  Paying  Agents or rescind the  designation  of any Paying  Agent or
approve a change in the office through which any Paying Agent acts, except that
we will be  required  to  maintain a Paying  Agent in each Place of Payment for
such series.

CONSENT TO SERVICE AND JURISDICTION

     We have designated CT Corporation System,  111-8th Avenue, 13th Floor, New
York,  New York  10011 as our  authorized  agent for  service of process in the
United States in any action,  suit or proceeding  arising out of or relating to
the  Indenture  or the debt  securities.  Any such action may be brought in any
Federal court (or, if such court refuses to take jurisdiction,  in any New York
state court)  located in the Borough of  Manhattan in The City of New York,  or

                                      20


brought under United States federal or state  securities laws or brought by the
Trustee, and Canadian Natural has irrevocably  submitted to the jurisdiction of
such courts.

GOVERNING LAW

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

ENFORCEABILITY OF JUDGMENTS

     Since a significant portion of all of our assets, as well as the assets of
a number of our  directors  and officers,  are outside the United  States,  any
judgment  obtained in the United States  against us or certain of our 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 Parlee  McLaws LLP that the laws of the Province
of Alberta and the federal laws of Canada  applicable  therein permit an action
to be brought in a court of competent  jurisdiction  in the Province of Alberta
on any final and conclusive  judgment in personam of any federal or state court
located  in the  State of New  York (a "New  York  Court")  against  us,  which
judgment  is  subsisting  and  unsatisfied  for a sum certain  with  respect to
enforceability of the Indenture and the debt securities that is not impeachable
as void or voidable or otherwise effective under the internal laws of the State
of New York if (i) the New York Court rendering such judgment had  jurisdiction
over the  judgment  debtor,  as  recognized  by the courts of the  Province  of
Alberta (and  submission by us in the Indenture to the  jurisdiction of the New
York  Court  will be  sufficient  for that  purpose  with  respect  to the debt
securities),  (ii) the judgment  debtor was properly  served in connection with
any action  leading to such  judgment,  (iii) such judgment was not obtained by
fraud or in a manner contrary to natural  justice and the  enforcement  thereof
would not be  inconsistent  with public  policy,  as such terms are  understood
under the laws of the Province of Alberta and  enforcement  thereof will not be
contrary to any order made by the Attorney  General of Canada under the Foreign
Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the
Competition  Act (Canada),  (iv) the  enforcement of such judgment would not be
contrary  to the  laws of  general  application  limiting  the  enforcement  of
creditors' rights including any other rule of law, whether equitable,  legal or
statutory, bankruptcy,  reorganization, winding up, moratorium and similar laws
and does not  constitute,  directly or indirectly,  the  enforcement of foreign
revenue, expropriatory, penal or public laws in the Province of Alberta, (v) no
new  admissible  evidence  relevant  to the action is  discovered  prior to the
rendering  of judgment by the court in the Province of Alberta,  (vi)  interest
payable on the debt securities is not  characterized by a court in the Province
of Alberta as interest payable at a criminal rate within the meaning of section
347 of the Criminal Code (Canada) and (vii) the action to enforce such judgment
is commenced within the appropriate  limitation periods,  except that any court
in the Province of Alberta may only give judgment in Canadian dollars.  We have
been advised by such counsel  that there is doubt as to the  enforceability  in
Canada in original actions, or in motions to enforce judgments of United States
courts,  of civil  liabilities  predicated  solely upon United  States  federal
securities laws.


                       CERTAIN INCOME TAX CONSIDERATIONS

     The applicable  prospectus  supplement will describe the material Canadian
federal income tax  consequences to an investor who is a citizen or resident of
the United States purchasing the debt securities, including whether payments of
principal,   premium,  if  any,  and  interest  will  be  subject  to  Canadian
non-resident withholding tax.

     The applicable  prospectus  supplement  will also describe  certain United
States  federal  income  tax  consequences  of  the  purchase,   ownership  and
disposition of the debt securities by an investor who is a United States person
(as defined in the applicable prospectus supplement),  including, to the extent
applicable,  certain relevant United States federal income tax rules pertaining
to capital gains and ordinary income treatment, original issue discount, backup
withholding and the foreign tax credit,  and any consequences  relating to debt
securities payable in a currency other than U.S. dollars, issued at an original
discount for United  States  federal  income tax purposes or  containing  early
redemption provisions or other special terms.

                                      21


                                  RISK FACTORS

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 PROSPECTUS  SUPPLEMENT
BEFORE PURCHASING THE DEBT SECURITIES IN THIS OFFERING. IN ADDITION TO THE RISK
FACTORS SET FORTH BELOW,  ADDITIONAL  RISK FACTORS ARE  DISCUSSED IN OUR ANNUAL
INFORMATION  FORM AND OUR  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS,  WHICH RISK
FACTORS ARE INCORPORATED HEREIN BY REFERENCE.


A SUBSTANTIAL  OR EXTENDED  DECLINE IN OIL AND GAS PRICES COULD HAVE A MATERIAL
ADVERSE EFFECT ON US.

     Our financial  condition  will be  substantially  dependent on, and highly
sensitive to, the prevailing prices of crude oil and natural gas.  Fluctuations
in crude oil or natural gas prices could have a material  adverse effect on our
operations  and  financial  condition and the value and amount of our reserves.
Prices for crude oil and  natural gas  fluctuate  in response to changes in the
supply of and demand for, crude oil and natural gas,  market  uncertainty and a
variety of additional factors beyond our control.  Oil prices are determined by
international supply and demand.  Factors which affect crude oil prices include
the actions of the Organization of Petroleum Exporting Countries, the condition
of the Canadian,  United  States and Asian  economies,  government  regulation,
political  stability in the Middle East and  elsewhere,  the foreign  supply of
oil, the price of foreign  imports,  the availability of alternate fuel sources
and  weather  conditions.  Natural  gas prices  realized by us will be affected
primarily in North America by supply and demand,  weather conditions and prices
of alternate  sources of energy.  Any  substantial  or extended  decline in the
prices of crude oil or natural gas could result in a delay or  cancellation  of
existing  or  future   drilling,   development  or  construction   programs  or
curtailment in production at some properties or resulting  unutilized long-term
transportation  commitments,  all of which could have a material adverse effect
on our revenues, profitability and cash flows.

     We conduct an annual  assessment  of the  carrying  value of our assets in
accordance with Canadian generally accepted accounting  principles.  If oil and
natural gas prices  decline,  the carrying value of our assets could be subject
to downward revisions, and our earnings could be adversely affected.

     A substantial  portion of our  production on a Boe basis is heavy oil. The
market  prices for heavy oil differ  from the  established  market  indices for
light and medium grades of oil, due  principally  to the higher  transportation
and refining costs  associated with heavy oil. As a result,  the price received
for heavy oil is  generally  lower than the price for medium and light oil, and
the production  costs  associated with heavy oil may be higher than for lighter
grades.  Future  differentials  are uncertain and any increase in the heavy oil
differentials could have a material adverse effect on our business.

OUR BUSINESS IS SUBJECT TO  ENVIRONMENTAL  LEGISLATION IN ALL  JURISDICTIONS IN
WHICH WE OPERATE AND ANY CHANGES IN SUCH LEGISLATION  COULD  NEGATIVELY  AFFECT
OUR RESULTS OF OPERATIONS.

     All  phases  of  the  oil  and  natural  gas   business   are  subject  to
environmental  regulation  pursuant to a variety of  Canadian,  United  States,
United  Kingdom,  European  Union  and  other  federal,  provincial,  state and
municipal  laws  and  regulations,   as  well  as   international   conventions
(collectively, "environmental legislation").

     Environmental  legislation  imposes,  among  other  things,  restrictions,
liabilities  and  obligations  in  connection  with the  generation,  handling,
storage,  transportation,  treatment and disposal of hazardous  substances  and
waste  and in  connection  with  spills,  releases  and  emissions  of  various
substances to the  environment.  Environmental  legislation  also requires that
wells,  facility sites and other  properties  associated with our operations be
operated, maintained, abandoned and reclaimed to the satisfaction of applicable
regulatory  authorities.  In addition,  certain types of operations,  including
exploration  and  development  projects  and  significant  changes  to  certain
existing  projects,  may require the submission  and approval of  environmental
impact  assessments  or  permit  applications.  Compliance  with  environmental
legislation  can require  significant  expenditures  and failure to comply with
environmental  legislation may result in the imposition of fines and penalties.
The costs of complying with environmental  legislation in the future may have a
material adverse effect on our financial condition or results of operations.

                                      22


     The Canadian Federal  Government (the "Federal  Government") has announced
its intention to regulate greenhouse gases ("GHG") and other air pollutants. In
late April 2007, the Federal Government announced its regulatory framework (the
"Framework")  that  outlines  its clean air and  climate  change  action  plan,
including  a target  to reduce  GHG  emissions  and a  commitment  to  regulate
industry on an emissions intensity basis in the short-term.  The regulations to
achieve  these  objectives  will be enacted  under the  Canadian  Environmental
Protection  Act, 1999 and will be introduced  starting in spring 2008. For GHG,
the Framework sets a 2010 implementation date for emissions intensity reduction
targets.

     The  government  of Alberta  (the  "Alberta  Government")  has also passed
legislation that regulates GHG emissions from certain facilities located in the
province. The Alberta Government's legislation is called the Climate Change and
Emissions  Management  Act  ("CCEMA").  In March 2007,  the Alberta  Government
proposed  amendments  to the CCEMA  that,  starting  on July 1, 2007,  requires
facilities  that emit more than 100,000  tonnes of GHG per year to reduce their
emissions  intensity  by 12%  from a  baseline  established  using  an  average
emissions  intensity  calculated from reported  emissions averaged over a three
year period depending on the type of facility. The companies that operate these
facilities  will be given options under the  regulations  to the CCEMA to allow
them to comply with this requirement.  These compliance  options include making
operating improvements, buying offsets to apply against their emission total or
making a contribution  at $15/tonne to a new Alberta  Government fund that will
invest in technology to reduce greenhouse gas emissions in the province.

     As these  programs  are under  development,  we are unable to predict  the
total impact or cost of the potential  regulations on our business.  Therefore,
it is possible  that we could face  increases  in  operating  costs in order to
comply  with GHG  emissions  legislation.  In  cooperation  with  the  Canadian
Association of Petroleum  Producers,  we will continue to work with the Federal
Government  and the  Alberta  Government  to develop an  approach  to deal with
climate  change  issues  that  manages  the cost and  administrative  burden of
compliance and supports continued investment in the sector.

     We  anticipate  that  changes in  environmental  legislation  may  require
reductions  in GHG  emissions  to the air from  our  operations.  Any  required
reductions  in the GHG emitted  from our  operations  could result in increased
capital expenditures and increased operating expenses, especially those related
to the Horizon  Project and our other existing and planned oil sands  projects.
This may  have an  adverse  effect  on our net  earnings  and  cash  flow  from
operations.  Future changes in environmental legislation could occur and result
in  stricter  standards  and  enforcement,  larger  fines  and  liability,  and
increased capital expenditures and operating costs, which could have a material
adverse effect on our financial condition or results of operations.

IF WE FAIL TO ACQUIRE OR FIND ADDITIONAL RESERVES,  OUR RESERVES AND PRODUCTION
WILL DECLINE MATERIALLY FROM CURRENT LEVELS.

     Our future oil and natural gas reserves and production,  and therefore our
cash flows and results of operations,  are highly dependent upon our success in
exploiting  our current  reserve base and acquiring or  discovering  additional
reserves. Without additions to our reserves through exploration, acquisition or
development  activities,  our reserves and production will decline over time as
reserves are depleted.  The business of exploring for,  developing or acquiring
reserves is capital intensive. To the extent our cash flows from operations are
insufficient to fund our capital  expenditures  and external sources of capital
become  limited  or  unavailable,  our  ability to make the  necessary  capital
investments  to maintain  and expand our oil and natural gas  reserves  will be
impaired.  In  addition,  we may be  unable  to find  and  develop  or  acquire
additional reserves to replace our oil and natural gas production at acceptable
costs.

                                      23


WE OPERATE IN A HIGHLY COMPETITIVE INDUSTRY.

     The energy  industry is highly  competitive in all aspects,  including the
exploration   for,  and  the  development  of,  new  sources  of  supply,   the
construction  and  operation  of  crude  oil  and  natural  gas  pipelines  and
facilities,   the  acquisition  of  oil  and  natural  gas  interests  and  the
transportation and marketing of crude oil, natural gas, natural gas liquids and
electricity.  We  will  compete  not  only  among  participants  in the  energy
industry,  but also between  petroleum  products and other energy sources.  Our
competitors will include  integrated oil and natural gas companies and numerous
other  senior oil and natural  gas  companies,  some of which may have  greater
financial and other resources than us.

WE ARE SUBJECT TO A NUMBER OF BUSINESS  RISKS THAT COULD  AFFECT OUR RESULTS OF
OPERATIONS.

     Other  business  risks  include  operational  risks,  the cost of  capital
available to fund exploration and development programs, fluctuations in foreign
exchange rates,  the  availability  of skilled labour and manpower,  regulatory
issues  and  taxation  and  the  requirements  of new  environmental  laws  and
regulations.  Exploring for,  producing and transporting  petroleum  substances
involves many risks,  which even a  combination  of  experience,  knowledge and
careful evaluation may not be able to overcome. These activities are subject to
a number of hazards which may result in fires, explosions, spills, blow-outs or
other unexpected or dangerous  conditions  causing  personal  injury,  property
damage,  environmental  damage and  interruption of operations.  Our liability,
property and business interruption  insurance may not provide adequate coverage
in certain unforeseen circumstances.

OUR  OWNERSHIP  INTERESTS IN FOREIGN OIL AND NATURAL GAS  PROPERTIES  INVOLVE A
NUMBER OF RISKS AND COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS.

     Our  foreign   investments   involve  risks   typically   associated  with
investments  in developing  countries  such as uncertain  political,  economic,
legal and tax  environments.  These  risks may  include,  among  other  things,
currency restrictions and exchange rate fluctuations, loss of revenue, property
and  equipment as a result of hazards such as  expropriation,  nationalization,
war,  insurrection and other political  risks,  risks of increases in taxes and
governmental  royalties,  renegotiation of contracts with governmental entities
and  quasi-governmental  agencies,  changes  in  laws  and  policies  governing
operations of foreign-based  companies and other  uncertainties  arising out of
foreign government sovereignty over our international  operations. In addition,
if a  dispute  arises  in our  foreign  operations,  we may be  subject  to the
exclusive jurisdiction of foreign courts or may not be successful in subjecting
foreign persons to the jurisdiction of a court in the United States or Canada.

     Our private  ownership of oil and natural gas properties in Canada differs
distinctly  from  our  ownership  interests  in  foreign  oil and  natural  gas
properties. In some foreign countries in which we do and may do business in the
future,  the state generally retains ownership of the minerals and consequently
retains  control of, and in many cases  participates  in, the  exploration  and
production  of  reserves.  Accordingly,  operations  outside  of Canada  may be
materially affected by host governments through royalty payments,  export taxes
and regulations,  surcharges,  value added taxes,  production bonuses and other
charges.  In  addition,  changes in prices and costs of  operations,  timing of
production  and other  factors  may affect  estimates  of oil and  natural  gas
reserve quantities and future net cash flows attributable to foreign properties
in a manner  materially  different than such changes would affect estimates for
Canadian properties. Agreements covering foreign oil and natural gas operations
also frequently contain provisions  obligating us to spend specified amounts on
exploration and development or to perform certain operations, or forfeit all or
a portion of the acreage subject to the contract.

OUR OIL AND  NATURAL  GAS RESERVE  DATA AND FUTURE NET  REVENUE  ESTIMATES  ARE
UNCERTAIN.

     There are numerous  uncertainties  inherent in  estimating  quantities  of
reserves,  including many factors beyond our control.  The reserve  information
set forth and incorporated by reference in this prospectus is our estimate.  In
general, estimates of economically recoverable oil and natural gas reserves and
the future  net cash flow  therefrom  are based  upon a number of  factors  and
assumptions made as of the date on which the reserve estimates were determined,
such as geological and engineering estimates which have inherent uncertainties,
the assumed  effects of  regulation by  governmental  agencies and estimates of
future commodity prices and operating costs, all of which may vary considerably
from actual  results.  All such  estimates  are, to some degree,  uncertain and
classifications  of  reserves  are  only  attempts  to  define  the  degree  of
uncertainty  involved.  For  these  reasons,   estimates  of  the  economically
recoverable oil,  natural gas liquids and natural gas reserves  attributable to
any particular group of properties,  the  classification of such reserves based

                                      24


on risk of recovery and  estimates of future net revenues  expected  therefrom,
prepared by different  engineers or by the same  engineers at different  times,
may vary substantially. Our actual production, revenues, taxes and development,
abandonment and operating expenditures with respect to our reserves will likely
vary from such estimates, and such variances could be material.

     Estimates  with respect to reserves  that may be developed and produced in
the future are often based upon  volumetric  calculations  and upon  analogy to
similar  types  of  reserves,  rather  than  upon  actual  production  history.
Estimates  based on these methods  generally are less reliable than those based
on actual production history.  Subsequent evaluation of the same reserves based
upon production  history will result in variations,  which may be material,  in
the estimated reserves.

THE DEBT SECURITIES WILL BE  STRUCTURALLY  SUBORDINATED TO ANY  INDEBTEDNESS OF
OUR SUBSIDIARIES.

     We carry on our business through  corporate and partnership  subsidiaries.
The  majority of our assets are held in one or more  corporate  or  partnership
subsidiaries.  Our results of operations  and ability to service  indebtedness,
including the debt securities,  are dependent upon the results of operations of
these  subsidiaries and the payment of funds by these subsidiaries to us in the
form of loans,  dividends or otherwise.  In the event of the liquidation of any
corporate or partnership subsidiary, the assets of the subsidiary would be used
first to repay the indebtedness of the subsidiary,  including trade payables or
obligations  under  any  guarantees,  prior  to  being  used  by us to pay  our
indebtedness,  including any debt securities.  Such  indebtedness and any other
future  indebtedness of our  subsidiaries  would be structurally  senior to the
debt  securities.  The Indenture  pursuant to which the debt securities will be
issued does not limit our ability or the ability of our  subsidiaries  to incur
additional unsecured indebtedness. See "Description of Debt Securities--Ranking
and Other Indebtedness".


                              PLAN OF DISTRIBUTION

     We may sell the debt  securities to or through  underwriters or dealers or
to one or more other purchasers directly or through agents.

     The  applicable  prospectus  supplement  will  describe  the  terms of the
offering,  including  the name or  names of any  underwriters  or  agents,  the
purchase price or prices of the debt securities to be offered,  the proceeds to
us from the sale of the debt  securities  to be  offered,  any  initial  public
offering  price,  any  underwriting  discount or commission  and any discounts,
concessions or commissions  allowed or reallowed or paid by any  underwriter to
other dealers. Any initial public offering price and any discounts, concessions
or commissions allowed or reallowed or paid to dealers may be changed from time
to time.

     The  debt  securities  may be  sold  from  time  to  time  in one or  more
transactions  at a fixed price or fixed  prices,  which may be  changed,  or at
market  prices  prevailing  at the time of sale,  at  prices  related  to these
prevailing market prices or at negotiated prices.

     If indicated in the  applicable  prospectus  supplement,  we may authorize
dealers or other  persons  acting as our  agents to  solicit  offers by certain
institutions  to  purchase  the debt  securities  directly  from us pursuant to
contracts  providing for payment and delivery on a future date. These contracts
will be subject only to the conditions  described in the applicable  prospectus
supplement or supplements,  which will also describe the commission payable for
solicitation of these contracts.

     We may enter into agreements to indemnify underwriters, dealers and agents
who  participate in the  distribution  of the debt  securities  against certain
liabilities,  including  liabilities under the U.S.  Securities Act of 1933, as
amended,  or to contribution  with respect to payments which the  underwriters,
dealers or agents may be required to make in respect of these liabilities.  The
underwriters,  dealers  and agents  with whom we enter into  agreements  may be
customers of,  engage in  transactions  with or perform  services for us in the
ordinary course of business.

     The debt  securities  will not be qualified for sale under the  securities
laws of any  province or  territory  of Canada and may not be offered,  sold or
delivered,  directly or  indirectly,  in Canada or to any resident of Canada in
contravention  of the  securities  laws of any province or territory of Canada.
Each  underwriter  and each dealer  participating  in the  distribution of debt
securities will agree that it will not, directly or indirectly,  offer, sell or
deliver  any such  debt  securities  purchased  by it in  connection  with that

                                      25


distribution  in Canada or to any  resident of Canada in  contravention  of the
securities laws of any province or territory of Canada.

     Each series of the debt  securities will be a new issue of securities with
no established  trading  market.  Unless  otherwise  specified in an applicable
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.  Some  broker-dealers  may make a market in the debt
securities,  but they will not be  obligated to do so and may  discontinue  any
market-making  activities at any time without notice. We cannot assure you that
there will be liquidity in the trading  market for the debt  securities  of any
series or that an active  public  market for the debt  securities of any series
will develop. If an active public trading market for the debt securities of any
series does not develop,  the market price and  liquidity of the series of debt
securities may be adversely affected.


                                 LEGAL MATTERS

     Unless  otherwise  specified  in  the  applicable   prospectus  supplement
relating to a series of debt  securities,  the validity of the debt  securities
will be passed upon for us by Parlee McLaws LLP, Calgary, Alberta, and by Paul,
Weiss,  Rifkind,  Wharton & Garrison LLP, New York, New York. As to all matters
of Canadian federal and Alberta law, Paul, Weiss,  Rifkind,  Wharton & Garrison
LLP may rely upon the  opinion of Parlee  McLaws LLP. As to all matters of U.S.
federal and New York law,  Parlee McLaws LLP may rely upon the opinion of Paul,
Weiss, Rifkind, Wharton & Garrison LLP.

     We are advised that, as of the date hereof, the partners and associates of
Parlee  McLaws LLP  beneficially  own,  directly or  indirectly,  less than one
percent  of our  outstanding  securities  and  none  of our  securities  or our
property are to be received by such persons.

INDEMNIFICATION

     Under the BUSINESS CORPORATIONS ACT (ALBERTA) (the "ABCA"), the Registrant
may  indemnify a present or former  director or officer or a person who acts or
acted at the Registrant's  request as a director or officer of a body corporate
of which the Registrant 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 is made a party by  reason  of being or  having  been a  director  or
officer of the  Registrant or that body  corporate,  if the director or officer
acted  honestly  and in good  faith  with a view to the best  interests  of the
Registrant,  and,  in the  case  of a  criminal  or  administrative  action  or
proceeding that is enforced by a monetary penalty,  had reasonable  grounds for
believing  that  his  conduct  was  lawful.  Such  indemnification  may  be  in
connection  with a derivative  action only with court  approval.  A director or
officer is entitled to indemnification from the Registrant as a matter of right
if he or  she  was  substantially  successful  on  the  merits,  fulfilled  the
conditions set forth above, and is fairly and reasonably entitled to indemnity.

     The by-laws of the  Registrant  provide that,  subject to the  limitations
contained in the ABCA, the Registrant shall indemnify a director or officer,  a
former director or officer,  or a person who acts or acted at the  Registrant's
request as a director or officer of a body corporate of which the Registrant is
or was a shareholder or creditor, and his heirs, executors,  administrators and
other legal representatives,  to the fullest extent which may from time to time
be permitted by the ABCA, from and against, (a) all costs, charges and expenses
that he incurs in respect of any civil,  criminal or  administrative  action or
proceeding  that is  proposed  or  commenced  against him by reason of being or
having been a director or officer of the  Registrant,  and (b) all other costs,
charges  and  expenses  that he sustains or incurs in respect of the affairs of
the  Registrant,  except  in  respect  of an  action  by or on  behalf  of  the
Registrant, or such body corporate, to procure a judgment in its favor.

     The by-laws of the Registrant  provide that the Registrant may, subject to
the limitations  contained in the ABCA, purchase and maintain insurance for the
benefit of any  director or officer as such against any  liability  incurred by
him in his capacity as a director or officer of the Registrant or as a director
or officer of any body corporate where he acts or acted in that capacity at the
Registrant's  request.  The Registrant  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 the
Registrant  pursuant  to the  foregoing  provisions,  the  Registrant  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.
