PetroKazakhstan maintains disclosure controls and procedures and internal
control over financial reporting designed to ensure that information required to
be disclosed in the reports filed under the Exchange Act, as amended, is
recorded, processed, summarized and reported within the time periods specified
in the Commission's rules and forms. PetroKazakhstan's Chief Executive Officer
and Chief Financial Officer, after evaluating the effectiveness of
PetroKazakhstan's disclosure controls and procedures (as defined in Exchange Act
Rule 13a-15(e)) as of the end of the period covered by this Form 40-F, concluded
that as of such date PetroKazakhstan's disclosure controls and procedures were
effective for the purpose for which they were designed.

During the fiscal year ended December 31, 2003, there were no changes in
PetroKazakhstan's internal control over financial reporting that have materially
affected, or are reasonably likely to materially affect, PetroKazakhstan's
internal control over financial reporting.

AUDIT COMMITTEE FINANCIAL EXPERT

The Board of Directors of the Company has determined that Jacques Lefevre is an
"audit committee financial expert" (as defined in paragraph 8(b) of General
Instruction B to Form 40-F).

CODE OF ETHICS

The Company has adopted a code of ethics (as that term is defined in Form 40-F)
that applies to its directors and employees (including its principal executive
officer, principal financial officer and controller). The Company will


                                       2


provide any person, upon request to the General Counsel and Corporate Secretary
of the Company, with a copy of the code of ethics free of charge. To date, no
amendment has been made to the code of ethics, nor there has been any waiver,
including implicit waiver, granted from the code of ethics required to be
disclosed in this annual report on Form 40-F.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

For the years ended December 31, 2003 and 2002, professional services were
performed by Deloitte & Touche LLP, the member firms of Deloitte Touche
Tohmatsu, and their respective affiliates, including TOO Deloitte &Touche that
has served as the principal accountant for the audit of the Company's annual
financial statements (collectively, "Deloitte & Touche").

AUDIT FEES: The aggregate audit fees billed by Deloitte & Touche were $407,000
in the year ended December 31, 2003 and $332,875 in the year ended December 31,
2002.

AUDIT-RELATED FEES: The aggregate audit related fees billed by Deloitte & Touche

-------------------
(1)  See Note 13 in the Company's consolidated financial statements for the year
     ended December 31, 2003.

(2)  Operating leases are for rail cars that the Company uses to transport crude
     oil, distribution centers for refined oil products and certain equipment
     used in upstream operations. The Company has no capital leases.

(3)  The Company has an obligation of $6.6 million for future site restoration
     costs that has been recorded as a liability as at December 31, 2003. The
     timing of future payments and the ultimate amount required is uncertain and
     the table has been prepared using the Company's best estimates.

(4)  Work commitments are non-discretionary expenditures for seismic and
     drilling that the Company is contractually committed to under the terms of
     its hydrocarbons licenses.

(5)  The Company has a future income tax liability that arises because
     Kazakhstan tax legislation allows the Company to depreciate some of its
     assets over a shorter period of time than the Company's accounting polices
     provide for. See Note 1 in the Company's consolidated financial statements
     for the year ended December 31, 2003. Changes in the Company's future
     income tax liability are reflected as future income taxes in the
     consolidated statement of income and retained earnings. These charges are
     not cash charges. The timing of when this liability will arise is
     uncertain.

(6)  Purchase obligations represent contractual obligations for goods and
     services for which the services have yet to be provided or for which the
     Company has not yet taken title to the goods. All other purchase
     commitments are discretionary.

AUDIT COMMITTEE

The Company has a separately designated standing audit committee established in
accordance with Section 3(a)(58)(A) of the Exchange Act. The Audit Committee is
comprised of James B.C. Doak, Jacques Lefevre and Jan Bonde-Nielsen. Jacques
Lefevre chairs the Audit Committee.
