                               PRINCIPAL DOCUMENTS

A.   ANNUAL INFORMATION FORM

For the Annual  Information  Form for the fiscal year ended  December 31, 2007,
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 the Consolidated
Financial  Statements of the  Registrant for the fiscal year ended December 31,
2007  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 15 -
Reconciliation  of Financial  Statements  to United States  Generally  Accepted
Accounting Principles in the 2007 Consolidated Financial Statements.

C.   MANAGEMENT'S DISCUSSION AND ANALYSIS

For  management's  discussion  and analysis,  see  Management's  Discussion and
Analysis of the Registrant for the fiscal year ended December 31, 2007 included
herein.

                    CERTIFICATIONS AND DISCLOSURES 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, 2007, 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  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

                                       4


     Procedures"  sections  of  Management's  Discussion  and  Analysis  of the
     Registrant for the fiscal year ended December 31, 2007, included herein.

C.   MANAGEMENT'S  ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL  REPORTING.
     The required  disclosure is included in the "Management Report on Internal
     Control  over  Financial  Reporting"  that  accompanies  the  registrant's
     Consolidated  Financial  Statements for the fiscal year ended December 31,
     2007, 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  "Independent   Auditors'  Report"  that
     accompanies the  registrant's  Consolidated  Financial  Statements for the
     fiscal year ended  December 31, 2007,  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, 2007,  there were no  significant  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, 2007,
