4.   SUMMARY OF MATERIAL CHANGE:

     On September 14, 2006,  Canadian Natural  announced it had entered into an
     agreement with Anadarko Petroleum  Corporation relating to the acquisition
     of  Anadarko  Canada  Corporation,  a  subsidiary  of  Anadarko  Petroleum
     Corporation  for  aggregate  consideration  of US$4.075  billion  (C$4.524

5.   FULL DESCRIPTION OF MATERIAL CHANGE:

     On September 14, 2006, Canadian Natural announced that it had entered into
     an agreement  relating to the acquisition of Anadarko  Canada  Corporation
     ("ACC"),  a subsidiary of Anadarko  Petroleum  Corporation,  for aggregate
     cash consideration of US$4.075 billion.

     The current  production,  before  royalties,  from the  working  interests
     acquired by Canadian Natural,  is approximately 358 million cubic feet per
     day of natural gas and 9,300  barrels  per day of crude oil and NGLs.  The
     assets include  approximately  1.5 million net  undeveloped  acres and key
     strategic  facilities  in the  high  growth  areas  of  Northeast  British
     Columbia and  Northwest  Alberta;  0.6 million net acres  developed;  0.25
     million acres fee lands; 7 major natural gas facilities and 2,800 miles of
     pipelines;  proved  reserves  before  royalties as at December 31, 2005 of
     1,561 bcf of  natural  gas and 48  million  barrels of crude oil and NGLs,
     based  on  public  disclosure  of  the  reserves  by  Anadarko   Petroleum
     Corporation,  adjusted for  royalties as at December 31, 2005.  ACC's land
     and production base are all located in Western Canada.

     FINANCING OF THE PROJECT AND HEDGING POLICIES

     Canadian Natural's balance sheet has significant  strength and flexibility
     to accommodate this acquisition,  however, the debt to book capitalization
     level  will be near the top end of  internal  targets.  To ensure  balance
     sheet  strength  going forward  Canadian  Natural has hedged a significant
     portion of the Company's natural gas and crude oil production for 2007 and
     2008 at prices that  protect  investment  returns.  The Company  will also
     consider the  divestiture of non strategic and non core properties to gain
     additional balance sheet flexibility.

     Financing will be through 3 year committed bank lines ($3 billion  through
     a new  bank  line and the  remainder  through  existing  bank  lines)  and
     reduction of $0.8-$1.0  billion of  conventional  capital  expenditures in
     2007 from 2006.  No equity  financing  is  required.  Debt  remains in the
     mid-range of debt to book capitalization targets in 2007.

     SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Certain  statements in this document or  incorporated  herein by reference
     may  constitute  "forward-looking  statements"  within the  meaning of the
     United States Private Litigation Reform Act of 1995. These forward-looking
     statements  can  generally be identified as such because of the context of
     the   statements   including   words  such  as  the  Company   "believes",
     "anticipates",  "expects",  "plans",  "estimates"  or words  of a  similar
     nature.

     The forward-looking  statements are based on current  expectations and are
     subject to known and unknown risks,  uncertainties and other factors which
     may cause the actual results,  performance or achievements of the Company,
     or industry results,  to be materially  different from any future results,
     performance or achievements  expressed or implied by such  forward-looking
     statements.  Such factors include,  among others: the general economic and
     business conditions which will, among other things,  impact demand for and
     market prices of the Company's  products;  the foreign  currency  exchange
     rates;  the economic  conditions in the countries and regions in which the
     Company conducts business; the political uncertainty, including actions of
     or  against  terrorists,  insurgent  groups  or other  conflict  including
     conflict between states; the industry capacity; the ability of the Company
     to implement its business strategy,  including exploration and development
     activities;  the ability of the Company to complete its capital  programs;
     the ability of the Company to transport its products to market;  potential
     delays or changes in plans with  respect  to  exploration  or  development
     projects or capital expenditures;  the availability and cost of financing;
     the success of  exploration  and  development  activities;  the production
     levels; the uncertainty of reserve estimates;  the actions by governmental
     authorities;  the government  regulations and the expenditures required to
     comply  with  them   (especially   safety  and   environmental   laws  and
     regulations);   the  site  restoration  costs;  and  other   circumstances
     affecting  revenues  and  expenses.  The  impact  of any one  factor  on a
     particular forward-looking statement is not determinable with certainty as
     such  factors are  interdependent  upon other  factors,  and  management's
     course  of  action  would  depend  upon  its   assessment  of  the  future
     considering all information then available.

     Statements  relating  to  "reserves"  are  deemed  to  be  forward-looking
     statements,  as they  involve  the  implied  assessment,  based on certain
     estimates and  assumptions  that the reserves  described can be profitably
     produced in the future.


                                       4


     Readers are cautioned that the foregoing list of important  factors is not
     exhaustive.  Although the Company believes that the expectations  conveyed
     by the  forward-looking  statements  are  reasonable  based on information
     available to it on the date such  forward-looking  statements are made, no
     assurances  can be given as to  future  results,  levels of  activity  and
     achievements.  All subsequent forward-looking statements,  whether written
     or oral,  attributable  to the Company or persons acting on its behalf are
     expressly qualified in their entirety by these cautionary statements.  The
     Company assumes no obligation to update forward-looking  statements should
     circumstances or management's estimates or opinions change.

     SPECIAL NOTE REGARDING CURRENCY, PRODUCTION AND RESERVES

     In this  document,  all  references to dollars  refer to Canadian  dollars
     unless  otherwise  stated.  Reserves and production data is presented on a
     before royalties basis unless otherwise stated. In addition,  reference is
     made  to oil and gas in  common  units  called  barrel  of oil  equivalent
     ("boe"). A boe is derived by converting six thousand cubic feet of natural
     gas to one  barrel  of  crude  oil  (6mcf:1bbl).  This  conversion  may be
     misleading,  particularly if used in isolation,  since the 6mcf:1bbl ratio
     is based on an energy equivalency at the burner tip and does not represent
     the value equivalency at the well head.

     Canadian  Natural  retains  qualified  independent  petroleum  engineering
     consultants to evaluate the Company's  proved and probable oil and natural
     gas  reserves  and  prepare  Evaluation  Reports  on the  Company's  total
     reserves. Canadian Natural has been granted an exemption from the recently
     adopted National  Instrument  51-101 - Standards of Disclosure for Oil and
     Gas  Activities  (NI  51-101)  which  prescribes  the  standards  for  the
     preparation  and  disclosure  of  reserves  and  related  information  for
     companies  listed  in  Canada.   This  exemption  allows  the  Company  to
     substitute  United  States   Securities  and  Exchange   Commission  (SEC)
     requirements for certain disclosures required under NI 51-101. The primary
     difference  between the two standards is the additional  requirement under
     NI 51-101 to disclose proved and probable reserves and future net revenues
     using forecast prices and costs.  Canadian Natural has elected to disclose
     proved reserves using constant prices and costs as mandated by the SEC and
     has also provided  proved and probable  reserves under the same parameters
     as voluntary  additional  information.  Another difference between the two
     standards is in the  definition  of proved  reserves.  As discussed in the
     Canadian Oil and Gas Evaluation  Handbook (COGEH),  the standards which NI
     51-101  employs,  the  difference in estimated  proved  reserves  based on
     constant pricing and costs between the two standards is not material.  The
     Board of Directors of the Company has a Reserves Committee,  which has met
     with  the  Company's  third  party  reserve  evaluators  and  carried  out
     independent  due  diligence  procedures  with  them  as to  the  Company's
     reserves.

     The reserves of ACC  disclosed by Anadarko  Petroleum  Corporation  in its
     Form 10K have been adjusted for royalties as at December 31, 2005.
