            CONSOLIDATED AUDITED ANNUAL FINANCIAL STATEMENTS AND
                   MANAGEMENT'S DISCUSSION AND ANALYSIS


         A.   ANNUAL INFORMATION FORM

         For the Annual Information Form for the fiscal year ended December 31,
         2006, see Exhibit 99.1 included herein.

         B.   AUDITED ANNUAL FINANCIAL STATEMENTS

         For consolidated audited financial statements, including the report of
         independent  chartered  accountants with respect thereto,  see Exhibit
         99.2, the Consolidated  Financial Statements of the Registrant for the
         fiscal year ended December 31, 2006 included herein.  The Registrant's
         financial  statements have been reconciled to United States  generally
         accepted  accounting  principles  ("US GAAP") as required by Form 40-F
         under the  Exchange  Act.  See Note 17 -  Reconciliation  of Financial
         Statements to United States Generally Accepted  Accounting  Principles
         in the 2006 Consolidated Financial Statements.

         C.   MANAGEMENT'S DISCUSSION AND ANALYSIS

         For   management's   discussion   and  analysis,   see  Exhibit  99.3,
         Management's  Discussion and Analysis of the Registrant for the fiscal
         year ended December 31, 2006 included herein.


                    CERTIFICATIONS AND DISCLOSURE REGARDING
                            CONTROLS AND PROCEDURES

(a)      CERTIFICATIONS.  See Exhibits  32.1 and 32.2 to this Annual  Report on
         Form 40-F.

(b)      DISCLOSURE CONTROLS AND PROCEDURES.  As of the end of the registrant's
         fiscal  year  ended   December  31,  2006,   an   evaluation   of  the
         effectiveness of the registrant's "disclosure controls and procedures"
         (as such term is  defined  in Rules  13a-15(e)  and  15d-15(e)  of the
         Securities  Exchange Act of 1934, as amended (the "Exchange Act")) was
         carried out by the registrant's  management with the  participation of
         the principal executive officer and principal financial officer. Based
         upon that evaluation, the registrant's principal executive officer and
         principal  financial officer have concluded that as of the end of that
         fiscal year, the registrant's  disclosure  controls and procedures are
         effective to ensure that  information  required to be disclosed by the
         registrant  in reports that it files or submits under the Exchange Act
         is (i) recorded,  processed,  summarized and reported  within the time
         periods  specified in  Securities  and Exchange  Commission  rules and
         forms  and  (ii)  accumulated  and  communicated  to the  registrant's
         management,  including its principal  executive  officer and principal
         financial  officer,  to  allow  timely  decisions  regarding  required
         disclosure.

         It should be noted that  while the  registrant's  principal  executive
         officer and principal  financial officer believe that the registrant's
         disclosure  controls  and  procedures  provide a  reasonable  level of
         assurance  that  they  are  effective,  they do not  expect  that  the
         registrant's  disclosure  controls and procedures or internal  control
         over financial  reporting will prevent all errors and fraud. A control
         system,  no matter how well  conceived or  operated,  can provide only


                                       4


         reasonable, not absolute, assurance that the objectives of the control
         system are met. Reference is made in the "Controls and Procedures" and
         "Evaluation  of  Disclosure  Controls  and  Procedures"   sections  of
         Management's  Discussion and Analysis of the Registrant for the fiscal
         year ended December 31, 2006, included herein.

(c)      MANAGEMENT'S   ANNUAL  REPORT  ON  INTERNAL   CONTROL  OVER  FINANCIAL
         REPORTING.  The  required  disclosure  is included in the  "Management
         Report"  that  accompanies  the  registrant's  Consolidated  Financial
         Statements for the fiscal year ended December 31, 2006,  filed as part
         of this Annual Report on Form 40-F.

(d)      ATTESTATION  REPORT OF THE  REGISTERED  PUBLIC  ACCOUNTING  FIRM.  The
         required  disclosure  is  included  in  the  "Auditors'  Report"  that
         accompanies the registrant's Consolidated Financial Statements for the
         fiscal  year ended  December  31,  2006,  filed as part of this Annual
         Report on Form 40-F.

(e)      CHANGES IN  INTERNAL  CONTROL  OVER  FINANCIAL  REPORTING.  During the
         fiscal  year ended  December  31,  2006,  there were no changes in the
         registrant's  internal  control  over  financial  reporting  that have
         materially  affected,  or are reasonably likely to materially  affect,
         the registrant's internal control over financial reporting.  Reference
         is made in the  "Controls  and  Procedures"  section  of  Management's
         Discussion  and Analysis of the  Registrant  for the fiscal year ended
         December 31, 2006, included herein.

                            NEW YORK STOCK EXCHANGE

         PRESIDING DIRECTOR AT MEETINGS OF NON-MANAGEMENT DIRECTORS

         The  Registrant  schedules  regular  executive  sessions  in which the
         Registrant's  "non-management  directors"  (as that term is defined in
         the rules of the New York  Stock  Exchange)  meet  without  management
         participation.  Steven Sharpe  serves as the  presiding  director (the
         "Chair  of the  Board")  at such  sessions.  Each of the  Registrant's
         non-management  directors is "independent" as such term is used in the
         rules of the Canadian  Securities  Commissions  and the New York Stock
         Exchange Corporate Governance Standards.

         COMMUNICATION WITH NON-MANAGEMENT DIRECTORS

         Unitholders may send communications to the Registrant's non-management
         directors by writing to Investors Relations, Petro-Canada Centre, West
         Tower,  Suite 3100, 150 - 6th Avenue SW, Calgary,  Alberta T2P 3Y7, or

         referred to the Chair of the Board for appropriate  action. The status
         of all outstanding  concerns  addressed to the Chair of the Board will
         be reported to the board of directors as appropriate.
