To the Shareholders

Dear Sir or Madam,

                         ONGOING CONNECTED TRANSACTIONS

1.   INTRODUCTION

     CNPC, which directly owns approximately 90% of the issued share capital of
the Company, is the controlling shareholder of the Company. Accordingly, CNPC is
a connected person of the Company and transactions between CNPC and the Company
constitute connected transactions for the Company for the purpose of the Listing
Rules.

     Under the Listing Rules, connected transactions are subject to the
reporting, announcement and/ or independent shareholders' approval requirements.
However, as such connected transactions have been, and/or will continue to be
carried out in the ordinary and usual course of business and occur on a regular
basis on normal commercial terms and on terms that are fair and reasonable so
far as the Shareholders are concerned, the Directors considered that it would
not be practical to make


                                       -5-

                              LETTER FROM THE BOARD

disclosure or if necessary, obtain the Shareholders' approval for each
transaction as it arises. Accordingly, the Company had previously obtained from
the Stock Exchange a waiver from strict compliance with the relevant
requirements of the Listing Rules in respect of connected transactions between
CNPC and the Company at the time of the Company's IPO in 2000. On 12 September
2002, the Company sought to renew the waiver in respect of the relevant Existing
Ongoing Connected Transactions. Subsequently, the Stock Exchange, on 26 November
2002, granted the Existing Waiver to the Company subject to, among other things,
the conditions set out in a letter of even date. The Existing Waiver will expire
on 31 December 2005. In addition to the Existing Ongoing Connected Transactions
and the Newco Continuing CT (approved by Independent Shareholders at the Recent
EGM), the Board would also like to draw the Shareholders' attention to the CRMSC
Transactions. The CRMSC Transactions are the connected transactions between the
Group and CRMSC, a connected person of the Company.

     The Ongoing Connected Transactions, comprising the Existing Ongoing
Connected Transactions, the Newco Continuing CT and the CRMSC Transactions, and
the Proposed Caps will be subject to reporting, announcement and Independent
Shareholders' approval (or Shareholders' approval in the case of the CRMSC
Transactions) requirements pursuant to the Listing Rules.

2.   EXISTING ONGOING CONNECTED TRANSACTIONS

     The connected transaction agreements listed below were initially entered
into between the Company and CNPC at the time of the Company's IPO in the year
2000. Subsequently, on 26 September 2002, a Supplemental Buildings Leasing
Agreement was entered into between the Company and CNPC. In addition, on 9 June
2005 and on 1 September 2005, the First Supplemental Comprehensive Agreement and
the Second Supplemental Comprehensive Agreement were entered into between the
Company and CNPC respectively. The Board expects that the Group will
continuously enter into the transactions with CNPC Group as stated in the
following agreements, which will constitute Ongoing Connected Transactions:

     -    Comprehensive Agreement (as to be amended by the First Supplemental
          Comprehensive Agreement and the Second Supplemental Comprehensive
          Agreement), and from time to time and as necessary, various product
          and service implementation agreements;

     -    Land Use Rights Leasing Contract;

     -    Buildings Leasing Contract (as amended by the Supplemental Buildings
          Leasing Agreement);

     -    Intellectual property licensing contracts, being the Trademark
          Licensing Contract, the Patent and Know-how Licensing Contract and the
          Computer Software Licensing Contract;

     -    Contract for the Transfer of Rights under Production Sharing
          Contracts; and

     -    Guarantee of Debts Contract.

     The Trademark Licensing Contract, the Patent and Know-how Licensing
Contract and the Computer Software Licensing Contract; the Contract for the
Transfer of Rights under Production Sharing Contracts; and the Guarantee of
Debts Contract, as specified in the Prospectus and Existing Waiver, are in
compliance with the requirements of Chapter 14A of the Listing Rules which took
effect from 31 March 2004 and are exempt from the reporting, announcement and
Independent


                                       -6-

                              LETTER FROM THE BOARD

Shareholders' approval requirements, as each of the applicable percentage
ratio(s) (other than the profits ratio) in respect of each of these connected
transactions is less than 0.1%. The Directors believe that these transactions
had been entered into in the ordinary course of business for the benefits of the
Company, and are in the interests of the Shareholders as a whole.

     COMPREHENSIVE AGREEMENT

          The Company and CNPC initially entered into the Comprehensive
     Agreement on 10 March 2000 for the provision (1) by the Group to the CNPC
     Group and (2) by the CNPC Group to the Group, of a range of products and
     services which may be required and requested from time to time by either
     party and/or its subsidiary companies and affiliates. The Comprehensive
     Agreement is to be amended by the First Supplemental Comprehensive
     Agreement and the Second Supplemental Comprehensive Agreement. There will
     be certain new continuing connected transactions between the Company and
     the Jointly-owned Companies, and as a result, the Company and CNPC entered
     into the Second Supplemental Comprehensive Agreement in respect of these
     new connected transactions, the details of which are set out in the
     paragraph headed "Second Supplemental Comprehensive Agreement" of this
     circular.

     (A)  Products and Services to be provided by the Group to the CNPC Group

          Under the Comprehensive Agreement, products and services to be
     provided by the Group to the CNPC Group include those relating to refined
     oil products, chemical products, natural gas, crude oil, supply of water,
     electricity, gas, heating, quantifying and measuring, quality inspection
     and other products and services as may be requested by the CNPC Group for
     its own consumption, use or sale from time to time.

     (B)  Products and Services to be provided by the CNPC Group to the Group

          The products and services to be provided by the CNPC Group to the
     Group are expected to be more numerous, both in terms of quantity and
     variety, than those to be provided by the Group to the CNPC Group. They
     have been grouped together and categorised according to the following types
     of products and services:

          Construction and technical services, including but not limited to
     exploration technology service, downhole operation service, oilfield
     construction service, oil refinery construction service and engineering and
     design service;

          Production services, including but not limited to water supply,
     electricity generation and supply, gas supply and communications;

          Supply of materials services, including but not limited to purchase of
     materials, quality control, storage of materials and delivery of materials;

          Social services, including but not limited to security services,
     education and hospitals;

          Ancillary services, including but not limited to property management,

                              LETTER FROM THE BOARD

     (C)  General Principles, Price and Terms

          The Comprehensive Agreement requires, in general terms that,

          -    the quality of products and services to be provided should be
               satisfactory to the recipient;

          -    the price at which such products and services are to be provided
               must be fair and reasonable; and

          -    the terms and conditions on which such products and services are
               to be provided should be no less favourable than those offered by
               independent third parties.

     (D)  Price Determination

          The Comprehensive Agreement details specific pricing principles for
     the products and services to be provided pursuant to the Comprehensive
     Agreement. If, for any reason, the specific pricing principle for a
     particular product or service ceases to be applicable, whether due to a
     change in circumstances or otherwise, such product or service must then be
     provided in accordance with the following general pricing principles:

          (a)  state-prescribed prices (at present, this applies to products and
               services such as refined oil products, natural gas, oil refinery
               construction, engineering and design, project monitoring and
               management), the definition of "state-prescribed price" is to be
               amended by the First Supplemental Comprehensive Agreement to mean
               price in respect of certain category of services determined by
               the laws, regulations, decisions, orders or policies, etc.
               enacted by governments of the relevant countries or regions
               (including but not limited to the central government, federal
               government, provincial government, state or coalition government
               or any organisation responsible for domestic ruling and foreign
               affairs in respect to certain specified territory, irrespective
               of its name, organisation or structure) or other regulatory
               departments;

               or

          (b)  where there is no state-prescribed price, then according to the
               relevant market prices (at present, this applies to products and
               services such as asset leasing, repair of machinery,
               transportation, purchase of material, and regional facilities),
               the definition of "market price" is to be amended by the First
               Supplemental Comprehensive Agreement to mean the price determined
               in accordance with the following order:

               (i)  the price charged by independent third parties in areas
                    where such type of service is provided and on normal terms
                    in the area where the service is being provided at that
                    time; or

               (ii) the price charged by independent third parties in nearby
                    areas where such type of service is provided and on normal
                    terms in the area or country adjacent to the area where the
                    service is being provided at that time;

               or


                                       -8-

                              LETTER FROM THE BOARD

          (c)  where neither (a) nor (b) is applicable, then according to:

               (i)  the actual cost incurred (at present, this applies to
                    products and services such as library information and
                    filing, maintenance of roads, retirement administration and
                    re-employment training); or

               (ii) the agreed contractual price, being the actual cost for the
                    provision of such product or service plus an additional
                    margin of not more than:

                    (xx) 15 per cent. (which includes finance costs, general and
                         administrative expenses and a profit margin) for
                         certain construction and technical services (at
                         present, this applies to products and services such as
                         geological surveying, drilling, well cementing,
                         logging, mud logging, well testing and oilfield
                         construction) provided that, such agreed contractual
                         price shall not be higher than the prices available for
                         the provision of such products and services in the
                         international market; and

                    (yy) 3 per cent. for all other types of products and
                         services priced in accordance with the agreed
                         contractual price (at present, this applies to products
                         and services such as downhole operations, technology
                         research, equipment repairing and supporting, equipment
                         antiseptic testing, communications, fire fighting,
                         quality inspection, storage of materials, delivery of
                         materials and training centers).

          The definitions of cost price and agreed contractual price include a
     provision that the aggregate value, in each future financial year, of all
     products and services which are required to be priced at cost or at agreed
     contractual prices to be provided under the Comprehensive Agreement, shall
     not exceed the aggregate value, calculated on an adjusted basis as if the
     Comprehensive Agreement had been in effect during the year ended 31
     December 1998, of all products and services which were required to be
     priced at cost or at agreed contractual prices during the year ended 31
     December 1998, being RMB36.9 billion (the "1998 Amount"), subject to any
     necessary adjustment for inflation or deflation, as appropriate, for the
     relevant year.

          However, if in any future financial year, the Company, due to any
     events or factors beyond the control of the Company (e.g. natural
     disasters) or the development of new projects, is required to purchase
     additional products and services required to be priced at cost or at agreed
     contractual prices exceeds the 1998 Amount (as adjusted for inflation or
     deflation as appropriate), then that decision to purchase such additional
     products or services should be authorised by the Board (with affirmative
     votes from the independent non-executive directors) and the management of
     the Company on the basis of any revised business plan and comprehensive
     financial analysis, to ensure that such purchases will allow for a
     reasonable return to the Company's shareholders. In the event that the
     relevant Proposed Caps are to be exceeded, the Company will comply with the
     requirements of the Listing Rules.

     (E)  Coordination of annual demand of products and services

          Two months prior to the end of each financial year, both parties are
     required to prepare and submit to each other an annual plan detailing the
     estimated demand for products and services to be rendered in accordance
     with the Comprehensive Agreement for the forthcoming financial year.

                              LETTER FROM THE BOARD

     (F)  Rights and Obligations

          Both the Group and the CNPC Group retain the right to choose to
     receive products and services, as contemplated under the Comprehensive
     Agreement, from independent third parties where the terms and conditions as
     to price or quality of products or services offered by such third parties
     may be superior to those offered by either of the Group or the CNPC Group,
     as appropriate.

          In addition, the provision of products and services by either party is
     on a non-exclusive basis and each party may provide products and services
     to other third parties, subject always to the obligation that each party
     must be able to provide those products and services which may be required
     to be provided in accordance with the Comprehensive Agreement and the
     annual plan then in force.

     (G)  Term and Termination

          The term of the Comprehensive Agreement was initially 10 years
     starting from the date when the Company's business license was issued. This
     term is to be amended by the Second Supplemental Comprehensive Agreement to
     3 years commencing from the effective date of the Second Supplemental
     Comprehensive Agreement, i.e., 1 January 2006.

          During the term of the Comprehensive Agreement, termination of the
     product and service implementation agreements described below may be
     effected from time to time by the parties to the product and service
     implementation agreements providing at least 6 months' written notice of
     termination in relation to any one or more categories of products or
     services. Further, in respect of any products or services already
     contracted to be provided, termination may not take place until after such
     products and services have been provided.

          In the event that CNPC proposes to terminate the provision of any
     products or services, and the Company is unable to find an alternative
     product or service provider (which fact shall be communicated by the
     Company to CNPC from time to time), then unless permitted by the Company,
     CNPC must continue to provide such products or services in accordance with
     the terms of the Comprehensive Agreement.

          Each product and service implementation agreement will set out the
     specific products and services requested by the relevant party and any
     detailed technical and other specifications which may be relevant to those
     products or services. The product and service implementation agreements may
     only contain provisions which are in all material respects consistent with
     the binding principles and guidelines and terms and conditions in
     accordance with which such products and services are required to be
     provided as contained in the Comprehensive Agreement.

          As the product and service implementation agreements are simply
     further elaborations on the provision of products and services as
     contemplated by the Comprehensive Agreement, they do not constitute new
     categories of connected transactions.

     LAND USE RIGHTS LEASING CONTRACT

          The Company entered into the Land Use Rights Leasing Contract with
     CNPC on 10 March 2000 under which CNPC has leased a total of 42,476 parcels
     of land in connection with and for the purpose of all aspects of the
     operations and business of the Group covering an aggregate area of
     approximately 1,145 million square meters, located throughout the PRC, to
     the Company for a term of 50 years at an annual fee of RMB2,000 million.
     The Directors believe that a term of 50 years is appropriate for the Land
     Use Rights Leasing Contract, since the Company is China's largest petroleum
     company engaging in exploration, development, sale and production of crude
     oil, natural gas and chemicals, and the long stability of a 50 year tenure
     is required to avoid the unnecessary disruption of its operations; the
     relevant land leases


                                      -12-

                              LETTER FROM THE BOARD

     are of material significance of its operations; and such tenure conforms
     with normal business practice in the PRC property market. The total fee
     payable for the lease of all such property may, after the expiration of 10
     years from the date of the Land Use Rights Leasing Contract, be adjusted
     (to reflect market conditions prevalent at such time of adjustment,
     including current market prices, inflation or deflation, as appropriate,
     and such other pertinent factors as may be considered in negotiating and
     agreeing to any such adjustment) by agreement between the Company and CNPC.
     In addition, any governmental, legal or other administrative taxes and fees
     required to be paid in connection with the leased properties will be borne
     by CNPC. However, any additional amount of such taxes payable as a result
     of changes in the PRC Government policies after the date of the contract
     shall be shared proportionately on a reasonable basis between CNPC and the
     Company.

          Savills (Hong Kong) Limited, an independent valuer, has reviewed the
     Land Use Rights Leasing Contract and has confirmed that the term of 50
     years and current rental payable by the Company to CNPC are fair and
     reasonable to the Company according to the Land Use Rights Leasing Contract
     and do not exceed the market level. The date of valuation is 30 June 2005.
     ICEA, the independent financial adviser to the Independent Board Committee
     and the independent shareholders of the Company, has opined that it is
     normal business practice for the Land Use Rights Leasing Contract to have a
     term of 50 years, the details of which are set out on pages 38 to 39 of
     this circular.

     BUILDINGS LEASING CONTRACT

          The Company entered into the Buildings Leasing Contract with CNPC on
     10 March 2000 pursuant to which the CNPC Group has leased to the Company a
     total of 191 buildings covering an aggregate area of 269,770 square meters,
     located throughout the PRC for the use by the Company for its business
     operation including the exploration, development and production of crude
     oil, the refining of crude oil and petroleum products, the production and
     sale of chemicals, etc.

          The 191 buildings were leased at a price of RMB145 per square meter
     per year, that is, at an aggregate annual fee of RMB39,116,650, for a term
     of 20 years. The Directors believe that a term of 20 years is appropriate
     for the Buildings Leasing Contract (as amended), since the Company is
     China's largest petroleum company engaging in exploration, development,
     sales and production of crude oil, natural gas and chemicals, and the long
     stability of a 20 year tenure is required to avoid the unnecessary
     disruption of its operations; the relevant building leases are of material
     significance of its operations; and such tenure conforms with normal
     business practice in the PRC property market. The Company is responsible
     for the payment of any governmental, legal or other administrative taxes
     and maintenance charges required to be paid in connection with these 191
     leased buildings. The Buildings Leasing Contract details the particulars of
     the buildings leased by members of the CNPC Group to the Company.

          Members of the CNPC Group which own one or more of the leased
     buildings will enter into individual building leasing contracts with the
     Company. The individual building leasing contracts may only contain
     provisions which are consistent with the terms and conditions of the
     Buildings Leasing Contract.

          One month prior to the end of each financial year, CNPC and the
     Company shall make and agree upon a rental fee distribution plan setting
     out specific prices for the buildings according to their geographical
     locations and conditions.

                              LETTER FROM THE BOARD

     Supplemental Buildings Leasing Agreement

          Further to the Buildings Leasing Contract mentioned above, the Company
     entered into a Supplemental Buildings Leasing Agreement (the "SUPPLEMENTAL
     BUILDINGS AGREEMENT") with CNPC on 26 September 2002 under which CNPC Group
     agreed to lease another 404 buildings to the Group in connection with and
     for the purpose of the operation and business of the Group covering an
     aggregate of approximately 442,730 square meters. Leasing of the units in
     the Supplemental Buildings Agreement is mainly attributable to the
     expansion of the Company's operations in the areas of oil and natural gas
     exploration, the West-East natural gas pipeline project and the
     construction of the Northeast refineries and chemical operation base. The
     annual fee payable under the Supplemental Buildings Agreement amounts to
     RMB157,439,540. The Company and CNPC will, based on their needs for
     production and operation or the changes of the market prices of the
     buildings, adjust the scale and the amount of all such buildings under the
     Buildings Leasing Contract as well as the Supplemental Buildings Agreement
     every three years. The Supplemental Buildings Agreement became effective on
     1 January 2003 and will expire at the same time as the Buildings Leasing
     Contract.

          Savills (Hong Kong) Limited, an independent valuer, has reviewed both
     the Buildings Leasing Contract and the Supplemental Buildings Agreement and
     has confirmed that the term of 20 years and current rental payable by the
     Company to CNPC are fair and reasonable to the Company according to the the
     Buildings Leasing Contract and the Supplemental Buildings Agreement and do
     not exceed the market level. The date of valuation is 30 June 2005. ICEA,
     the independent financial adviser to the Independent Board Committee and
     the independent shareholders of the Company, has opined that it is normal
     business practice for the Buildings Leasing Contract and the Supplemental
     Buildings Agreement to have a term of 20 years, the details of which are
     set out on pages 35 to 37 of this circular.

     share capital of the Company, CNPC is a connected person of the Company

     NEWCO

          As Newco will become a non wholly-owned subsidiary of the Company upon

     PetroChina & CRMSC Oil Marketing, is a connected person of the Company

     Shareholders' approval in the case of CRMSC Transactions) requirements
     pursuant the Listing Rules.

6.   REASONS FOR AND BENEFITS OF THE ONGOING CONNECTED TRANSACTIONS

     EXISTING ONGOING CONNECTED TRANSACTIONS AND NEWCO CONTINUING CT

          The Existing Ongoing Connected Transactions and Newco Continuing CT
     are entered into for the necessity and benefits of the Company. The
     Company, one of the largest companies in the PRC in terms of sales, is
     engaged in a broad range of petroleum and natural gas-related activities.
     CNPC, on the other hand, is an enterprise whose business operations cover a
     broad spectrum of upstream and downstream activities, domestic marketing
     and international trade, technical services, and equipment manufacturing
     and supply. CNPC is a major producer and supplier of petrochemical
     products. CNPC is also involved in the provision of operational services
     and technical support in such areas as geophysical prospecting, well
     drilling, logging, well testing, downhole operations, oilfield surface
     facilities construction, pipeline construction, refining and petrochemical
     projects, and manufacturing and supply of petroleum equipment.


                                      -16-

                              LETTER FROM THE BOARD

          In view of the strengths and scope of CNPC's business activities and
     the strong favourable support that such Existing Ongoing Connected
     Transactions and Newco Continuing CT would bring to the Company's business
     activities, the Board believes that the Existing Ongoing Connected
     Transactions and Newco Continuing CT are entered into for the necessity and
     benefits of the Company. The Board also notes the long smooth cooperation
     history between the Company and CNPC in relation to such transactions.

          The Existing Ongoing Connected Transactions and Newco Continuing CT
     are and will be conducted in the ordinary and usual course of business of
     the Group. These transactions will continue to be agreed on an arm's length
     basis with terms that are fair and reasonable to the Company. Due to the
     long-term relationships between the Group and CNPC Group, the Board
     considers it to be beneficial to the Company and in the interests of the
     Shareholders as a whole to continue the Existing Ongoing Connected
     Transactions and Newco Continuing CT with CNPC Group as these transactions
     have facilitated and will continue to facilitate the operation of the
     Group's business.

     CRMSC TRANSACTIONS

          The CRMSC Transactions are essential to the Company. The Company has
     strengths in terms of resources. CRMSC is a major corporation of materials
     supply in the PRC. It has a dominant position in diesel purchase and
     distribution in the market. In view of the overwhelming economic power and
     market share of CRMSC and the new situation of the refined oil market of
     the PRC in the wake of China's accession to the WTO, the combined strengths
     of the Company and CRMSC in terms of resources and market share come into
     play. The ongoing connected transactions between the Group and CRMSC
     enhance the competitiveness of both the Group and CRMSC. With PetroChina &
     CRMSC Oil Marketing as the major supplier of diesel for railway engines,
     the Company has found strong and favourable support for its operations from
     CRMSC.

          The CRMSC Transactions are conducted in the ordinary and normal course
     of business of the Company, and are at arm's length. The Directors believe
     that these transactions are fair and reasonable to the Company and in the
     interests of the Shareholders as a whole. In view of the long-term working
     relationship of the Company with CRMSC, it is favourable for the Company to
     expand its market share and the Company's development.

          Notes:

          Bases for the Proposed Caps:

          1.   The annual proposed caps for the products and services to be
               provided by the Group to the CNPC Group have been determined with
               reference to the historical transactions and transaction amounts
               in providing products and services by the Group to the CNPC
               Group; the estimated business growth of the Group; the estimated
               business growth of the CNPC Group; the potential fluctuations and
               increases in the prices of crude oil, petrochemical products,
               natural gas and other oil products and services both in the
               international market and in the domestic market; and the increase
               in transaction amounts as a result of the completion of the
               Transactions.

                              LETTER FROM THE BOARD

          2.   The annual proposed caps for the provision of construction and
               technical services have been determined with reference to the
               completed transactions and transaction amounts for the
               construction and technical services provided by the CNPC Group to
               the Group; the estimated business growth of the Company; and the
               transaction amounts as a result of increase in size of the Group
               upon the completion of the Transactions.

               The Group has obtained construction and technical services from
               CNPC Group in the ordinary course of business, and as one of the
               most experienced companies in the world, the construction and
               technical services provided to the Group are quality services.
               The CNPC Group is also one of the few companies in the PRC which
               provide quality petrochemical related construction and technical
               services.

          3.   The annual proposed caps for the production services provided by
               the CNPC Group to the Group have been determined with reference
               to the previous transactions conducted and transaction amounts in
               respect of production services provided by the CNPC Group to the
               Group; the estimated business growth of the Group; and the
               potential fluctuations and increases in the international and the
               PRC market prices of crude oil, petroleum and petrochemical
               products, leading to higher energy costs in the production
               process.

               Production services mainly consist of water supply, electricity
               generation and supply, gas supply by CNPC Group to the Group and
               the supply of petroleum and petrochemical products by
               Jointly-owned Companies to the Group. The Group is of the view
               that annual proposed caps have provided sufficient increment for
               the Company to implement its future business development plans
               and have been determined on a fair and reasonable basis.

          4.   The annual caps for the supply of materials services paid by the
               Group to the CNPC Group have been determined by reference to the
               estimated business growth of the Company; and changes in the
               volume of purchases by the Group.

               The CNPC Group is one of the leading buyers of petrochemical raw
               materials in the PRC. With the economy of scale and to increase
               the collective bargaining power of the CNPC Group, the
               centralised materials purchase by the CNPC Group thus stabilise
               the purchase prices of the Company's raw materials.

               With the Company's dominant position and increase in the
               petroleum and petrochemical industries of the PRC, as well as the
               increase in the size of business, these ongoing connected
               transactions and transaction amounts are expected to increase.
               The Group is of the view that the Proposed Caps provide
               sufficient increment for the Company to implement future business
               development and planning.

          5.   The annual proposed caps for social and ancillary services have
               been determined with reference to the previous transactions
               conducted and transaction amounts in respect of the social and
               ancillary services provided by the CNPC Group to the Group; the
               estimated business growth of the Group; and the transaction
               amounts as a result of increase in size of the Group upon the
               completion of the Transactions.

               Considering the future development and acquisitions of the Group
               which will increase the demand for certain social and ancillary
               services, the Group has prudently set the annual proposed caps at
               the same level as the existing annual caps.

          6.   The annual proposed caps for the financial services (aggregate of
               loans, interests and other relevant charges) provided by CPFC to
               the Group have been determined with reference to the estimated
               business growth of the Group; the competitive interest rates and
               charges offered by CPFC; and the transaction amounts as a result
               of increase in size of the Group upon the completion of the
               Transactions, in particular, the financing provided by CPFC to
               Newco.

               To optimise cash flow management and capital efficiency of the
               Group and the CNPC Group, there is the specific target of
               providing a centralised financial management by CPFC, which
               provides a full range of financial services to the Group and the
               CNPC Group, including but not limited to deposit services, loan
               services, project financing, clearing services, national debt
               redemption, entrustment loans, financial advisory and insurance
               services.

                              LETTER FROM THE BOARD

               The Group is of the view that the annual proposed caps have
               provided increments sufficient for the Group to implement future
               business development and planning, and that the annual proposed
               caps have been determined on a reasonable basis.

          7.   The annual proposed caps for the financial services (aggregate of
               deposits and interests) provided by the CNPC Group to the Group
               have been determined with reference to the estimated business
               growth of the Group; the Group's historical cashflow and levels
               of deposits; the competitive interest rates offered by CPFC; and
               the transaction amounts as a result of increase in size of the
               Group upon the completion of the Transactions.

               As mentioned above, in order to optimise cash flow management and
               capital efficiency of the Group and the CNPC Group, there is the
               specific target of providing a centralised financial management
               by CPFC, which provides a full range of financial services to the
               Group and the CNPC Group.

               The Group is of the view that the annual proposed caps have
               provided increments sufficient for the Group to implement future
               business development and planning, and that the annual proposed
               caps have been determined on a reasonable basis.

          8.   The annual proposed caps for the financial services, including
               but not limited to guarantees and entrustment loans, to be
               provided by the Group to the Jointly-owned Companies (such as
               Newco) have been determined with reference to the business
               development and financing needs of the Jointly-owned Companies;
               and the acquisition opportunities which may arise from time to
               time in the international market. It has been pointed out by the
               Group in the Recent Circular to the Shareholders dated 30 June
               2005 that it is the Group's strategic objective of becoming an
               international petroleum company with significant oil assets both
               onshore and offshore as well as in both the PRC and international
               markets. The Group is of the view that the provision of financial
               services to the Jointly-owned Companies will enable them to have
               sufficient funding for future expansion.

          9.   The Directors consider that pursuant to the Land Use Rights
               Leasing Contract, the annual proposed caps in respect of the land
               leases provided by the CNPC Group to the Group are sufficient for
               the Group to implement future business development and planning.
               Each of the annual proposed caps comprises of the annual leasing
               fee of RMB2,000 million and the relevant PRC tax of RMB260
               million, which are in accordance with the Land Use Rights Leasing
               Contract. Savills (Hong Kong) Limited, an independent valuer, has
               appraised the lands leased to the Group.

          10.  The Directors consider that pursuant to the Buildings Leasing
               Contract (as amended by the Supplemental Buildings Agreement),
               the annual proposed caps in respect of the building leases
               provided by the CNPC Group to the Group, which are lower than the
               existing annual limit for 2005 due to a reduced requirement by
               the Group, are sufficient for the Group to implement future
               business development and planning. The annual proposed caps are
               in accordance with Buildings Leasing Contract (as amended by the
               Supplemental Buildings Agreement), and Savills (Hong Kong)
               Limited, an independent valuer, has appraised the buildings
               leased to the Group.

          11.  The historical revenue in relation to the provision of the
               products and services which are the subject matter of CRMSC
               Products and Services Agreement between the Company and CRMSC was
               RMB4,041 million for the six months ended 30 June 2005. There had
               not been any connected transactions between the Company and CRMSC
               before 1 January 2005.

               The annual proposed caps have been determined with reference to
               (i) the relevant pricing principles, i.e., the State-prescribed
               prices; (ii) the historical transaction levels for the same type
               of transaction before CRMSC became a connected person of the
               Company; and (iii) the estimated future transaction levels based
               on the market needs in the coming 3 years.

To the Independent Board Committee and
   the independent shareholders of the Company

Dear Sirs,

                         ONGOING CONNECTED TRANSACTIONS

     We refer to our engagement as independent financial adviser to advise the
Independent Board Committee and the independent shareholders of the Company with
respect to the terms of the Ongoing Connected Transactions and determination of
the Proposed Caps of the Ongoing Connected Transactions for each of the three
years ending 31 December 2006, 2007 and 2008. Pursuant to the Listing Rules, the
Ongoing Connected Transactions are subject to, among other things, the approval
of the independent shareholders of the Company at a general meeting of the
Company. Details of the Ongoing Connected Transactions are summarized in the
Company's circular to its Shareholders dated 22 September 2005 (the "CIRCULAR").
This letter has been prepared for inclusion in the Circular and capitalized
terms used in this letter shall have the same meaning as defined in the Circular
unless the context otherwise requires.

     The Company had previously obtained from the Stock Exchange a waiver from
strict compliance with the relevant requirements of the Listing Rules in respect
of ongoing connected transactions between CNPC and the Company at the time of
the Company's IPO in 2000. On 12 September 2002, the Company sought to renew the
waiver in respect of the Existing Ongoing Connected Transactions. Subsequently,
the Stock Exchange, on 26 November 2002, granted the Existing Waiver to the
Company subject to, inter alia, the conditions set out in a letter from the
Stock Exchange. The Existing Waiver will expire on 31 December 2005. In addition
to the Existing Ongoing Connected Transactions, the Independent Shareholders
have already approved the Newco Continuing CT at the Recent EGM, and there are
CRMSC Transactions, which are new ongoing connected transactions between the
Group and connected person other than CNPC, namely CRMSC.

     Our opinion only applies to the Ongoing Connected Transactions. Other
ongoing connected transactions which are not subject to approval by independent
shareholders of the Company are not within the scope of our work.

     We, ICEA, have been retained as the independent financial adviser to advise
the Independent Board Committee and the independent shareholders of the Company
as to whether or not the terms of the Ongoing Connected Transactions are fair
and reasonable so far as the independent shareholders of the Company are
concerned and whether the Proposed Caps of the Ongoing Connected Transactions
are reasonably determined.

                        LETTER FROM ICEA CAPITAL LIMITED

Independent Board Committee and the independent shareholders of the Company, we
have not been involved in the negotiations in respect of the terms of the
Ongoing Connected Transactions. Our opinion with regard to the terms thereof has

parties to the Ongoing Connected Transactions will be fully performed in

obligation to update this opinion to take into account events occurring after
the date on which this opinion is delivered to the Independent Board Committee
and the independent shareholders of the Company. This letter is for the
information of the Independent Board Committee and the independent shareholders
of the Company solely in connection with their consideration of the Ongoing
Connected Transactions and, except for its inclusion in the Circular, is not to

          1.1.1 Price Determination

               The Comprehensive Agreement (as amended by the First Supplemental
          Comprehensive Agreement and the Second Supplemental Comprehensive
          Agreement) specifies pricing principles based on:

               (a)  state-prescribed prices (at present, this applies to
                    products and services such as refined oil products, natural
                    gas, oil refinery construction, engineering and design,
                    project monitoring and management), where "state-prescribed
                    price" means prices in respect of certain category of
                    products or services determined by the laws, regulations,
                    decisions, orders or policies, etc. enacted by governments
                    of the relevant countries or regions (including but not
                    limited to the central government, federal government,
                    provincial government, state or coalition government or any
                    organisation responsible for domestic ruling and foreign
                    affairs in respect to certain specified territory,
                    irrespective of its name, organization or structure) or
                    other regulatory departments;

                    or

               (b)  where there is no state-prescribed price, then the relevant
                    market prices (at present, this applies to products and
                    services such as asset leasing, repair of machinery,
                    transportation, purchase of material, and regional
                    facilities), where "market price" means the price determined
                    in the following order:

                    (i)  the price charged by independent third parties in areas
                         where such type of service is provided and on normal
                         terms in the area where the service is being provided
                         at that time; or

                    (ii) the price charged by independent third parties in
                         nearby areas where such type of service is provided and
                         on normal terms in the area or country adjacent to the
                         area where the service is being provided at that time;

                    or

               (c)  where neither (a) nor (b) is applicable, then:

                    (i)  the actual cost incurred (at present, this applies to
                         products and services such as library information and
                         filing, maintenance of roads, retirement administration
                         and re-employment training); or

                    (ii) the agreed contractual price, being the actual cost for
                         the provision of such product or service plus an
                         additional margin of not more than:

                         (xx) 15 per cent. (which includes finance costs,
                              general and administrative expenses and a profit
                              margin) for certain construction and technical
                              services (at present, this applies to products and
                              services such as geological surveying, drilling,
                              well cementing, logging, mud logging, well testing
                              and oilfield construction) provided that, such
                              agreed contractual price shall not be higher than
                              the prices available for the provision of such
                              products and services in the international market;
                              and

                        LETTER FROM ICEA CAPITAL LIMITED

                         (yy) 3 per cent. for all other types of products and
                              services priced in accordance with the agreed
                              contractual price (at present, this applies to
                              products and services such as downhole operations,
                              technology research, equipment repairing and
                              supporting, equipment antiseptic testing,
                              communications, fire fighting, quality inspection,
                              storage of materials, delivery of materials and
                              training centers).

               The Company advises that no more than 15% and 3% additional
          margin respective to the categories of products stated above is what
          they believe to be a norm in the PRC across relevant industries. Such
          margin has taken into account, among other things, the administrative
          expenses incurred for providing such products or services, as well as
          the profit margin required by comparable companies providing such
          services. Based on our findings, we note that listed companies on the
          Stock Exchange across the respective industries generally achieved an
          operating margin higher than or comparable to 15% and 3%. As such, we
          are of the opinion that the 15% and 3% profit margins charged by CNPC
          to the Company are not unreasonable.

               For detailed description of the terms in relation to the
          Comprehensive Agreement (as amended by the First Supplemental
          Comprehensive Agreement and the Second Supplemental Comprehensive
          Agreement), please refer to the "Letter from the Board" set out in
          this Circular.

               Based on the above, the priority is set from (a) to (c) such that
          the price mechanism in (b) and (c) would only apply where the
          preceding price mechanism(s) are inapplicable. As (a) and (b) are
          based on the applicable state-prescribed prices and market prices,
          including the applicable local or national market prices, we are of
          the opinion that the above mechanism is fair and reasonable as far as
          the Independent Shareholders are concerned.

               We also noted that the rates of financial services provided under
          the Comprehensive Agreement (as amended by the First Supplemental
          Comprehensive Agreement and the Second Supplemental Comprehensive
          Agreement) are determined in accordance with the relevant interest
          rates and standards for fees as promulgated by the People's Bank of
          China. Such rates should be no less favourable than those offered by
          independent third parties. As the rates of financial services are
          determined by reference to the People's Bank of China guidelines, we
          are of the opinion that the pricing mechanism is fair and reasonable
          as far as the Independent Shareholders are concerned.

                        LETTER FROM ICEA CAPITAL LIMITED

          1.2.1 Price Determination of Buildings Leasing Contract

               The Company entered into the Buildings Leasing Contract with CNPC
          on 10 March 2000 pursuant to which the CNPC Group has leased to the
          Company a total of 191 buildings covering an aggregate area of 269,770
          square meters, located throughout the PRC for the use by the Company
          for its business operation including the exploration, development and
          production of crude oil, the refining of crude oil and petroleum
          products, the production and sale of chemicals, etc.

               The 191 buildings were leased at a price of RMB145 per square
          meter per year with an aggregate annual fee of RMB39,116,650 for a
          term of 20 years. The Company is responsible for the payment of any
          governmental, legal or others administrative taxes and maintenance
          charges required to be paid in connection with these 191 leased
          buildings.

               Members of the CNPC Group which own one or more of the leased
          buildings will enter into individual building leasing contracts with
          the Company. The individual building leasing contracts may only
          contain provisions which are consistent with the terms and conditions
          of the Buildings Leasing Contract. According to the Company, such
          individual building leasing contracts were also leased at a price of
          RMB145 per square meter per year.

               One month prior to the end of each financial year, CNPC and the
          Company shall meet and agree upon a rental fee distribution plan
          setting out specific prices for the buildings according to their
          geographical locations and conditions.

               Savills (Hong Kong) Limited, an independent valuer, has reviewed
          the Buildings Leasing Contract and has confirmed that the terms and
          the aggregate amount payable by the Company to CNPC is fair and
          reasonable to the Company and do not exceed the market level. Savills
          (Hong Kong) Limited value the rentals of the leased properties which
          are leased by the Company from CNPC, by adopting "Direct Comparison
          Approach" by making reference to comparable rental evidences as
          available on the market in the locality.

               We are of the view that a 20 years term for the Buildings Leasing
          Contract is reasonable and beneficial to the Company, based on the
          following reasons:

               -    based on our discussion with Savills (Hong Kong) Limited, we
                    note that it is normal business practice in the PRC to have
                    buildings leasing contracts of this type with such duration;

               -    we believe the long lease term is to the benefit of the
                    Company and would help to minimize any potential disruption
                    to the Company's business operations arising from the expiry
                    of a short lease term; and

               -    certain assets of the Company are located in the buildings
                    leased from CNPC, and the continued operation of such assets
                    would depend on the Company's ability to continue to occupy
                    the relevant buildings.

               We also note in the Buildings Leasing Contract that the Company
          has the right to terminate the aforementioned contract, in whole or in
          part, with six months' notice to CNPC.

          1.2.2 Price Determination of Supplemental Buildings Agreement

               Further to the Buildings Leasing Contract mentioned above, the
          Company entered into a Supplemental Buildings Agreement with CNPC on
          26 September 2002 under which the CNPC Group agreed to lease another
          404 buildings to the Group in connection with and for the purpose of
          the operation and business of the Group covering an aggregate of
          approximately 442,730 square meters. Leasing of the units in the
          Supplemental Buildings Agreement is mainly attributable to the
          expansion of the Company's operations in the areas of oil and natural
          gas exploration, the West-East natural gas pipeline project and the
          construction of the Northeast refineries and chemical operation base.
          The annual fee payable under the Supplemental Buildings Leasing
          Agreement amounts to RMB157,439,540. The Company and CNPC will, based
          on their needs for production and operation or the changes of the
          market prices of the buildings, adjust the scale and the amount of all
          such buildings under the Buildings Leasing Contract as well as the
          Supplemental Buildings Agreement every three years. The Supplemental
          Buildings Agreement became effective on 1 January 2003 and will expire
          at the same time as the Buildings Leasing Contract, i.e. 5 November
          2019.

               Savills (Hong Kong) Limited has reviewed the Supplemental
          Buildings Agreement and has confirmed that the terms and the aggregate
          amount payable by the Company to CNPC is fair and reasonable to the
          Company and do not exceed the market level. Savills (Hong Kong)
          Limited value the rentals of the leased properties which are leased by
          the Company from CNPC, by adopting "Direct Comparison Approach" by
          making reference to comparable rental evidences as available on the
          market in the locality.

               We confirmed that it is normal business practice for the
          Supplemental Buildings Contract for such long periods, based on the
          following reasons:

               -    based on our discussion with Savills (Hong Kong) Limited, we
                    note that it is normal business practice in the PRC to have
                    buildings leasing contracts of this type with such duration;

               -    we believe the long lease term is to the benefit of the
                    Company and would help to minimize any potential disruption
                    to the Company's business operations arising from the expiry
                    of a short lease term; and

               -    certain assets of the Company are located in the buildings
                    leased from CNPC, and the continued operation of such assets
                    would depend on the Company's ability to occupy the relevant
                    buildings.

               We also note in the Supplemental Buildings Agreement that the
          Company has the right to terminate the aforementioned contract, in
          whole or in part, with six months notice to CNPC.

          1.3.1 Price Determination of Land Use Rights Leasing Contract

               The Company entered into the Land Use Rights Leasing Contract
          with CNPC on 10 March 2000 under which CNPC has leased a total of
          42,476 parcels of land in connection with and for the purpose of all
          aspects of the operations and business of the Group covering an
          aggregate area of approximately 1,145 million square meters, located
          throughout the PRC, to the Company for a term of 50 years at an annual
          fee of RMB2,000 million. The total fee payable for the lease of all
          such property may, after the expiration of 10 years from the date of
          the Land Use Rights Leasing Contract, be adjusted (to reflect market
          conditions prevalent at such time of adjustment, including current
          market prices, inflation or deflation, as appropriate, and such other
          pertinent factors as may be reasonably considered in negotiating and
          agreeing to any such adjustment) by agreement between the Company and
          CNPC. In addition, any governmental, legal or other administrative
          taxes and fees required to be paid in connection with the leased
          properties will be borne by CNPC. However, any additional amount of
          such taxes payable as a result of changes in the policies of the PRC
          government after the date of the contract shall be shared
          proportionately on a reasonable basis between CNPC and the Company.
          Such additional taxes payable will be shared proportional to the land
          area occupied respectively by CNPC and the Company.

               Savills (Hong Kong) Limited, an independent valuer, has reviewed
          the Land Use Rights Leasing Contract and has confirmed that the terms
          and the aggregate amount payable by the Company to CNPC is fair and
          reasonable to the Company and do not exceed the market level. Savills
          (Hong Kong) Limited value the rentals of the leased properties which
          are leased by the Company from CNPC, by adopting "Direct Comparison
          Approach" by making reference to comparable rental evidences as
          available on the market in the locality.

               We are of the view that it is normal business practice for the
          Land Use Rights Leasing Contract for a term of 50 years, based on the
          following reasons:

               -    based on our discussion with Savills (Hong Kong) Limited, we
                    note that it is normal business practice in the PRC to have
                    land use rights leasing contracts of this type with such
                    duration;

               -    we believe the long lease term is to the benefit of the
                    Company and would help to minimize any potential disruption
                    to the Company's business operations arising from the expiry
                    of a short lease term; and

                        LETTER FROM ICEA CAPITAL LIMITED

               -    certain assets of the Company are located on the lands
                    leased from CNPC, and the continued operation of such assets
                    would depend on the Company's ability to occupy the relevant
                    land.

               We also note in the Land Use Rights Leasing Contract that the
          Company has the right to terminate the aforementioned contract, in
          whole or in part, with six months notice to CNPC.

          1.4.1 Price Determination of CRMSC Products and Services Agreement

               The price of any product and service provided pursuant to the
          CRMSC Products and Services Agreement shall be determined by reference
          to the state-prescribed price or the market price where there is no
          state-prescribed price.

               As the price determination is by reference to the
          state-prescribed price or the market-price where there is no
          state-prescribed price, we are of the opinion that the above mentioned
          pricing determination is fair and reasonable as far as the
          Shareholders are concerned.

2.   REASONS FOR AND BENEFITS OF THE ONGOING CONNECTED TRANSACTIONS

     As mentioned in the Circular, the Ongoing Connected Transactions are
entered into for the necessity and benefits of the Company. The Company, one of
the largest companies in the PRC in terms of sales, is engaged in a broad range
of petroleum and natural gas-related activities. CNPC, on the other hand, is an
enterprise whose business operations cover a broad spectrum of upstream and
downstream activities, domestic marketing and international trade, technical
services, and equipment manufacturing and supply. CNPC is a major producer and
supplier of petrochemicals in the PRC. CNPC is also involved in the provision of
operational services and technical support in such areas as geophysical
prospecting, well drilling, logging, well testing, down hole operations,
oilfield surface facilities construction, pipeline construction, refining and
petrochemical projects, and manufacturing and supply of petroleum equipment in
the PRC.

     In view of the strengths and scope of CNPC's business activities and the
strong favorable support that such Ongoing Connected Transactions would bring to
the Company's business activities, we concur with the Board that the Ongoing
Connected Transactions are entered into for the necessity and benefits of the
Company.

     As for the CRMSC Transactions, the Directors are of the opinion that those
transactions are beneficial to the Group. The Group has strengths in terms of
oil resources; while CRMSC is a major corporation of materials supply in the
PRC. The ongoing connected transactions between the Group and CRMSC enhance the
competitiveness of the Group and CRMSC in the oil market in the PRC.

     3.1  PRODUCTS AND SERVICES PROVIDED BY THE GROUP TO THE CNPC GROUP

          The Proposed Caps for the products and services to be provided by the
     Group to the CNPC Group are determined with reference to:

          (a)  the previous transactions conducted and transaction amounts in
               respect of products and services provided by the Group to the
               CNPC Group;

          (b)  the CNPC Group's estimate of its business growth;

          (c)  the volatility and possible increase in the international and the
               PRC market price of refined oil products, chemical products,
               natural gas, crude oil and other products and services; and

          (d)  the increase in transaction amount as increased by the enlarged
               Group resulting from the completion of the Transactions.

          We noted from the analysis in respect of the Proposed Caps for
     products and services provided by the Group to the CNPC Group that the
     increase in Proposed Caps for the three years ending 31 December 2006, 2007
     and 2008 is mainly due to the increase in sales of refined oil products,
     chemical products, and crude oil. In anticipation of (i) higher volume of
     products demanded from the CNPC Group; and (ii) high volatility and
     uncertainly of the future market price in relation to refined oil products,
     chemical products, and crude oil, we concur with the view of the Directors
     that larger caps should be set.

          During the two years ended 31 December 2003 and 2004, the growth in
     products and services provided by the Group to the CNPC Group has increased
     year-on-year by 20% and 56% respectively. Based on the projected annualized
     figures for the year-ended 31 December 2005 and the Proposed Caps, for each
     of the three years ending 31 December 2006, 2007 and 2008, the products and
     services provided by the Group to the CNPC Group would grow annually by
     38%, 23% and 15% respectively. We consider the growth of the Proposed Caps
     for each of the three years ending 31 December 2006, 2007 and 2008 to be
     modest and reasonable and the Proposed Caps are reasonably determined.


                                      -41-

                        LETTER FROM ICEA CAPITAL LIMITED

          Given the dominant position of the Group in the petroleum and
     petrochemical industry in the PRC, and the increase in turnover and
     activities of the CNPC Group, the quantity and amount of future
     transactions between the Group and the CNPC Group are expected to increase.
     The Directors are of the view that the Proposed Caps provide sufficient
     increment for the Group to capture the Group's future anticipated expansion
     plan. We are of the view that given the uncertainty in the world energy
     market, the escalating energy prices and business development of the Group,
     the Proposed Caps will provide a reasonable certainty of maintaining supply
     to the CNPC Group within the Proposed Caps.

     3.2  CONSTRUCTION AND TECHNICAL SERVICES PROVIDED BY THE CNPC GROUP TO THE
          GROUP

          The Proposed Caps for construction and technical services are
     determined with reference to:

          (a)  the previous transactions conducted and transaction amounts in
               respect of construction and technical services provided by the
               CNPC Group to the Group;

          (b)  the Group's estimate of its business growth; and

          (c)  the increase in transaction amount as increased by the enlarged
               Group resulting from the completion of the Transactions. Pursuant
               to the circular of the Company dated 30 June 2005, those
               additional ongoing connected transactions principally include the
               provision of services including but not limited to geophysical
               surveying, well drilling, logging, well testing, downhole
               operations and oilfield construction by the CNPC Group to the
               Company.

          The CNPC Group has extensive experience in exploration and development
     of crude oil and natural gas projects in the world, offering a premier
     construction and technical services to the Group. The Group has, from time
     to time, obtained, in the ordinary and usual course of business,
     construction and technical services from the CNPC Group to update and
     optimize existing products and processes and develop new technology,
     products, processes and equipment relating to the business of the Group.

          The CNPC Group is also one of the few companies in the PRC that
     provides premier petrochemical related construction and technical services.
     The services and terms offered by independent third parties are difficult
     to match the same quality services provided by the CNPC Group. The CNPC
     Group offers advantages including safety, reliability, technical expertise,
     understanding of existing facilities and experience in providing
     construction and technical services.

          The transaction amounts of construction and technical services are
     closely related to the capital expenditure incurred by the Group. The
     greater the amount of capital expenditure, the greater will be the
     anticipated amount for construction and technical services. For each of the
     three years ended 31 December 2002, 2003 and 2004, the amount of
     construction and technical services provided by the CNPC Group to the Group
     compared to the amount of capital investment by the Group represent a ratio
     of approximately 0.5. Applying the same basis, and after reviewing the
     capital expenditure budget of the Group for each of the three years ending
     31 December 2006, 2007 and 2008, we consider the Proposed Caps approximate
     such ratios. Therefore, we are of the view that the Proposed Caps are
     determined on a fair and reasonable basis.


                                      -42-

                        LETTER FROM ICEA CAPITAL LIMITED

          We have discussed with the management of the Company on the future
     capital expenditure plan and considered the plan was prepared by Company
     after due and careful enquiry. We are of the view that the Proposed Caps
     provide sufficient increment for the Group to capture the Group's future
     anticipated expansion plan.

     3.3  PRODUCTION SERVICES PROVIDED BY THE CNPC GROUP TO THE GROUP

          The Proposed Caps for production services are determined with
     reference to:

          (a)  previous transactions conducted and transaction amounts in
               respect of production services provided by the CNPC Group to the
               Group;

          (b)  the Group's estimate of its business growth; and

          (c)  the volatility and possible increase in the international and the
               PRC market price of crude oil, petroleum and petrochemical
               products, leading to higher energy costs during the production
               process.

          Production services provided by the CNPC Group to the Group including,
     but not limited to, water supply, electricity generation and supply, gas
     supply and communications. The Directors are of the view that the Proposed
     Caps provide sufficient increment for the Group to capture the Group's
     future anticipated expansion plan.

          Based on the information provided by the Company, the transaction
     amount for the production services provided by CNPC Group to the Group
     amounted to RMB8,945 million for the six months ended 30 June 2005,
     representing an annualized figure of RMB17,890 million for the year ending
     31 December 2005. Comparing the annualized figure of the transaction from
     this category for the year ending 31 December 2005 and the Proposed Caps,
     the Proposed Caps increased from RMB17,890 million (annualized figure for
     the year ended 31 December 2005) to RMB32,647 million for the year ending
     31 December 2008, representing a modest compound annual growth rate of
     22.2%. Considering (i) the volatility and possible increase in the
     international and the PRC market price of crude oil, petroleum and
     petrochemical products, leading to a higher energy costs during the
     production process; and (ii) substantial capital investment of the Company
     during the three years ending 31 December 2008, we are of the opinion that
     the Proposed Caps are determined on a fair and reasonable basis.

          We have discussed with the management of the Company on the future
     business plan and considered the plan was prepared by Company after due and
     careful enquiry. We consider that entering into the ongoing connected
     transaction is fair and reasonable so far as the Independent Shareholders
     are concerned.

     3.4  SUPPLY OF MATERIAL SERVICES PROVIDED BY THE CNPC GROUP TO THE GROUP

          The aforementioned annual caps for supply of material services
     provided by the Group to the CNPC Group are determined with reference to:

          (a)  business growth of the Group;

          (b)  change in volume of purchases by the Group; and

          (c)  change in payment arrangement between the Group and the CNPC
               Group.

                        LETTER FROM ICEA CAPITAL LIMITED

          The CNPC Group is one of the leading buyers of petrochemical raw
     materials in the PRC and offers a range of products compatible to the
     Group's needs. With the economy of scale and the collective bargaining
     power of the CNPC Group, the centralized material purchase by the CNPC
     Group stabilizes the purchase price of the Group's raw materials.

          Compared to the historical amount of supply of materials services
     provided by the CNPC Group to the Group for the three years ended 31
     December 2004, there is a significant increase in the amount in the
     Proposed Caps. Based on our understanding, the significant increase is
     mainly due to the change in payment arrangement. Some material vendors have
     recently indicated to the CNPC Group that, future purchases of certain
     categories of materials require prepayment. Correspondingly, the CNPC Group
     will charge the Group for those materials that require prepayments on gross
     amount basis. As similar materials purchases have been charged on
     commission basis during the three years ended 31 December 2004, the change
     in payment arrangement to a gross amount basis requires significant
     increase in the Proposed Caps. The Company has represented to us that the
     commission charged for the three years ended 31 December 2004 ranged from
     3% to 10%. The Proposed Caps for different categories are set out as below:



                                                        PROPOSED CAPS (IN RMB MILLION)

     (i)   Supply of material services charged on
           commission basis                                  1,054   1,074   1,033

           Total                                             4,471   4,331   4,500


          Given the Group's dominant position and increase in turnover and
     activities of the Group in the petroleum and petrochemical industry in the
     PRC, the number and amount of these future transactions is expected to
     increase. We are of the view that the Proposed Caps provide sufficient
     increment for the Group to capture the Group's future anticipated expansion
     plan.

          Based on the above, we consider that entering into the ongoing
     connected transaction is fair and reasonable so far as the Independent
     Shareholders are concerned.

     3.5  SOCIAL AND ANCILLARY SERVICES PROVIDED BY THE CNPC GROUP TO THE GROUP

          The Proposed Caps for social and ancillary services are determined
     with reference to:

          (a)  the previous transactions conducted and transaction amounts in
               respect of social and ancillary services provided by the CNPC
               Group to the Group;

          (b)  the Group's estimate of its business growth;

          (c)  the increase in transaction amount as increased by the enlarged
               Group resulting from the completion of the Transactions; and

          (d)  the increase in transaction amount as increased by the possible
               acquisitions in future.

          Considering (i) the growth of the Group and increase in demand of
     certain social and ancillary services in future, in particular renovation
     of aged properties and possible future acquisitions leading to increment of
     demand of social and ancillary services; (ii) possible increment in
     transaction amounts by future possible acquisitions; and (iii) the nature
     of the existing specific contracts for such services have not been revised,
     we are of the view that it is prudent and reasonable for the Group to set
     the Proposed Caps at the same level as the annual caps of the Existing
     Waiver.

          We are of the opinion that the Proposed Caps are determined reasonably
     and entering into the ongoing connected transaction is fair and reasonable
     so far as the Independent Shareholders are concerned.

     3.6  FINANCIAL SERVICES (AGGREGATE OF THE AVERAGE DAILY OUTSTANDING
          PRINCIPAL OF LOANS; THE TOTAL AMOUNT OF INTEREST PAID IN RESPECT OF
          THESE LOANS AND OTHER RELEVANT CHARGES) PROVIDED BY THE CNPC GROUP TO
          THE GROUP

          The Proposed Caps for financial services provided by CPFC (a
     subsidiary of CNPC) to the Company are determined with reference to:

          (a)  the estimated growth business growth of the Group;

          (b)  the interest rates offered by CPFC and its changes; and

          (c)  the increase in transaction amount as increased by the enlarged
               Group resulting from the completion of the Transaction, in
               particular, the financing provided by CPFC to Newco.

          To optimize cash flow management and capital efficiency of the Group
     and the CNPC Group, there is a specific target to maintain a centralized
     financial management of the Group and the CNPC Group through CPFC, an
     authorized financial institution under the regulation of the People's Bank
     of China. CPFC offers a full range of financial services to the Group and
     the CNPC Group, including but not limited to deposit services, loan
     facilities, project financing, settlement services, financial advisory and
     insurance services. With the continuous effort to centralize financial
     management, the Group's utilization of loan facilities provided by CPFC is
     expected to increase gradually.


                                      -45-

                        LETTER FROM ICEA CAPITAL LIMITED

          The financial services provided by the CNPC Group to the Group are by
     reference to the People's Bank of China guidelines, including the interest
     rates and foreign exchange rates, as well as guidelines published by PRC
     self-regulatory bodies such as the associations of finance companies.

          Upon the completion of the Transactions, the Directors expect
     significant amounts of loan to be provided by CPFC to Newco in foreign
     currency. According to a notice issued by a PRC government authority to the
     CNPC Group on 5 November 2004, it has granted the CNPC Group a permission
     to maintain a foreign exchange account. As part of the growth strategy of
     Newco is to acquire overseas energy assets, the Directors anticipate that
     the acquisition activities of Newco will utilize major portion of the
     foreign exchange account of the CNPC Group. Due to the business development
     and increase in foreign exchange currency needed by the Group and the CNPC
     Group for its operations, the Directors anticipate the upper limit of
     foreign exchange account could be favourably adjusted in future. With the
     anticipated increase in upper limit of foreign exchange account, the amount
     of loan provided by the CNPC Group to Newco, which are denominated in
     foreign currency, will further increase for the three years ending 31
     December 2008.

          To properly reflect the amount of financial services demanded by the
     Group from the CNPC Group, the Directors have adjusted the Proposed Caps to
     a level lower than the annual caps in the Existing Waiver.

          We concur with the view of the Directors that the Proposed Caps are
     reasonably sufficient for the Group to capture the Group's future
     anticipated expansion plan. We are of the opinion that the Proposed Caps
     are reasonably determined.

          Based on the above, we consider that entering into the ongoing
     connected transaction is fair and reasonable so far as the Independent
     Shareholders are concerned.

     3.7  FINANCIAL SERVICES (AGGREGATE OF THE AVERAGE DAILY AMOUNT OF DEPOSITS;
          AND THE TOTAL AMOUNT OF INTEREST RECEIVED IN RESPECT OF THESE
          DEPOSITS) PROVIDED BY THE CNPC GROUP TO THE GROUP

          The Proposed Caps for financial services provided by the Group to the
     CNPC Group are determined with reference to:

          (a)  the business growth of the Group;

          (b)  the Group's historical cash flow movements and level of deposits;

          (c)  the interest rate offered by the CPFC and its changes; and

          (d)  the increase in transaction amount as increased by the enlarged
               Group resulting from the completion of the Transactions.

          As mentioned above, in order to optimize cash flow management and
     capital efficiency of the Group and the CNPC Group, there is a specific
     target to maintain a centralized financial management of the Group and the
     CNPC Group through CPFC. CPFC is a subsidiary of CNPC and offers a full
     range of financial services to the Company and CNPC, including but not


                                      -46-

                        LETTER FROM ICEA CAPITAL LIMITED

     limited to deposit services, loan facilities, project financing, settlement
     services, financial advisory and insurance services. With the continuous
     effort of central financial management, the utilization of deposit services
     provided by CPFC is forecasted to increase gradually.

          The financial services provided by the CNPC Group to the Group are by
     reference to the People's Bank of China guidelines, including the interest
     rates and foreign exchange rates, as well as guidelines published by PRC
     self-regulatory bodies such as associations of finance companies.

          As most of the inter-company settlements with the Group and CNPC Group
     are made through the network of CPFC, the increase in business operations
     made the annual caps of the Existing Waiver of RMB4,500 million
     insufficient for the daily operations. However, to avoid substantial
     reporting work involved in revising the annual caps of the Existing Waiver,
     the Company has to constantly monitor the balance maintained at CPFC, and
     has reallocated the cash balance from CPFC to other accounts when
     necessary.

          To highlight the substantial growth in the Group cash and bank
     balance, the cash and bank balance was RMB11,304 million as at 31 December
     2004 and RMB69,857 million as at 30 June 2005, representing a growth of 6.2
     times in cash and bank balance for the six months ended 30 June 2005 when
     comparing with the balance as at 31 December 2004. In order to cope with
     the significant increase in cash and bank balance, and to satisfy the
     target to maintain a centralized financial management by CPFC, higher
     Proposed Caps will be needed. Based on a forecast report of the deposit
     service provided by the Group, which take into account the following
     factors including, among other things, (i) daily settlements between
     inter-companies; and (ii) growth in business of the Group, a Proposed Caps
     of RMB9,000 million will be required for each of the three years ending 31
     December 2006, 2007 and 2008. We have the opinion that, to facilitate the
     business operations of the Group, and to provide necessary buffer for the
     future growth in business, the amount of Proposed Caps are fair and
     reasonable.

          We concur with the view of the Directors that the Proposed Caps
     provide sufficient increment for the Group to capture the Group's future
     anticipated expansion plan, and are of the view that the Proposed Caps are
     reasonably determined.

          3.8.1 Financial services provided by the Group to Newco

               The Proposed Caps for financial resources provided by the Group
          to Newco include, among other things, loan guarantees, entrustment
          loans and their related charges, and are determined with reference to:

               (a)  the business development of Newco;

               (b)  the financial requirement of Newco for possible acquisition
                    opportunities arises from time to time; and

               (c)  the financing provided to Orifuel Sinoven S.A.
                    ("SINOVENSA").

               Upon the completion of the Transactions, Newco will be owned by
          the Company as to 50%. The businesses of Newco are conducted outside
          the PRC, and include, among other things, exploration, development,
          production and sales of crude oil and natural gas. In order to support
          the business development of Newco, particularly to increase the
          exploration and production of crude oil and natural gas, the Directors
          are of the opinion that funding provided by the Group to Newco will be
          needed. Those fundings will be provided in the form of loan guarantees
          and/or entrustment loans.

               As mentioned in the circular to the Shareholders dated 30 June
          2005, the strategy of the Group is to become an internationalized oil
          company with significant oil and gas assets both onshore and offshore
          as well as in both the PRC and international markets. Newco will act
          as the platform for the Group's future acquisition of international
          oil and gas assets. With Newco's international experience, the Group
          can seek acquisition targets in a more aggressive and effective manner
          which will facilitate the development of a significant international
          asset base. The Directors are of the view that the financial services
          provided by the Group will facilitate such efforts.

                        LETTER FROM ICEA CAPITAL LIMITED

               Amidst the globally tight energy supply, we understand the top
          priority among top PRC petroleum companies is to secure overseas
          energy reserves. The Group, being the largest petroleum company in
          PRC, is prepared to secure good acquisition targets when the
          opportunity appears. As overseas acquisition is part of the growth
          strategy of Newco, the Directors considered that the Proposed Caps
          will provide the resources for the Company to speed up the process in
          making acquisitions and developments in future. Therefore, improving
          the Group's chances of securing prime energy reserves.

               In April 2001, the governments of the PRC and Venezuela signed a
          memorandum to strengthen their co-operation in the development of
          orimulsion, a rich natural resource in Venezuela. Subsequently on 27
          December 2001, a Venezuela registered company named Sinovensa was set
          up. Sinovensa is a joint venture owned as to 40% by Newco, 30% by PFOC
          and 30% by the independent third parties. Due to the increase in
          market demand of orimulsion, Sinovensa was set up to capture the
          growth in this energy resource. The operation field of Sinovensa is
          approximately 114.6 square miles, with enough reserve capacity to
          supply 30 years of exploration. Pursuant to the agreement signed
          between PFOC and Sinovensa on 17 November 2003, Sinovensa will supply
          approximately 6.5 million tons of orimulsion to the Company annually
          for 30 years. Due to the expanding business development of Sinovensa,
          the Directors anticipated that financial resources by the Group to
          Sinovensa through Newco will be needed for each of the three years
          ending 31 December 2006, 2007 and 2008. The financial resources will
          be provided in the form of loan guarantees and/or entrustment loans
          through Newco, the largest shareholder of Sinovensa. The financial
          resources to be provided to Sinovensa will be used for funding
          exploration, development, production and sales of orimulsion, as well
          as for operational needs of Sinovensa.

               We note that it is a common practice amongst PRC major
          state-owned companies to have financing services provided by the
          parent groups to the related companies.

               The Directors are of the view that the Proposed Caps provide
          sufficient capacity for the Newco and Sinovensa to capture the future
          anticipated expansion plan.

          3.8.2 Financial services provided by the Group to PFOC

               The Proposed Caps for financial services to be provided by the
          Group to PFOC, amongst other things, include loan guarantees,
          entrustment loans and their related charges, and are determined with
          reference to:

               (a)  the business development of PFOC; and

               (b)  the development plan of Zhan Jiang Zhong Yue Energy Company
                    Limited (the "ZHAN JIANG ENERGY COMPANY").

               As part of the business plan to increase the usage of orimulsion
          in the PRC and strengthen the co-operation with Venezuela energy
          projects, PFOC and Zhan Jiang Energy Company were set up for the
          purpose of downstream businesses development.

               As present, PFOC is owned 31.4% by the Company, 35.73% by CNPC
          and the rest by independent third parties. With the steady supply of
          orimulsion from Sinovensa as mentioned above, PFOC serve an important
          function of importing, sales, distribution and refinery of orimulsion
          in the PRC. The Directors considered that PFOC is the largest

          company in respect of production and sales of orimulsion in the PRC.
          In view of the increase in market demand of orimulsion and the
          business development of PFOC, the Group need to provide financial
          support to PFOC for each of the three years ending 31 December 2006,
          2007 and 2008. The Directors are of the view that the financial
          support can reinforce PFOC's status as the largest orimulsion resource
          agent and producer in the PRC. The financial support will be used for,
          among other things, construction of orimulsion storage facilities,
          construction of port facilities and building up a transportation
          network, as well as other capital investments and general working
          capital needs by PFOC.

               Zhan Jiang Energy Company is registered in the PRC and was set up
          on 28 June 2004. Zhan Jiang Energy Company is owned as to 51% by PFOC
          and 49% by independent third parties. The purpose of setting up Zhan
          Jiang Energy Company is for the production of electricity using
          orimulsion as fuel. The electricity output capacity of the power
          station to be constructed is approximately 1,200 mega watts, and when
          put into production, it will help to alleviate the energy shortage in
          the Guangdong province. In order to support the development of Zhan
          Jiang Energy Company, the Directors are of the opinion that funding
          provided by the Group to Zhan Jiang Energy Company through PFOC will
          be needed. Those funding will be provided in the form of loan
          guarantees and/or entrustment loans. The funding will be used mainly
          for the construction of Zhan Jiang Energy Company and general working
          capital needs.

               We note that it is a common practice amongst PRC major
          state-owned companies to have financial support provided by the parent
          groups to the related companies.

               We concur with the view of the Directors that the Proposed Caps
          provide sufficient increment for PFOC and Zhan Jiang Energy Company to
          capture the their future anticipated plans. We consider that the
          Proposed Caps are reasonably determined.

     3.9  FEE FOR BUILDINGS LEASES PAID BY THE COMPANY TO CNPC

          We note that Savills (Hong Kong) Limited, an independent valuer
     retained by the Company has appraised the buildings leased to the Company
     by CNPC pursuant to the Building Leasing Contract dated 27 March 2000, and
     the buildings leased pursuant to the Supplemental Buildings Agreement dated
     26 September 2002, and confirmed that the current rentals payable by the
     Company to CNPC and the Proposed Caps under these contracts and agreement
     are fair and reasonable to the Company and do not exceed the market level.
     Savills (Hong Kong) Limited value the rentals of the leased properties
     which are leased by the Company from CNPC, by adopting "Direct Comparison
     Approach" by making reference to comparable rental evidences as available
     on the market in the locality.

          The Directors consider that pursuant to the Buildings Leasing Contract
     (as amended by the Supplemental Buildings Agreement), the annual proposed
     caps in respect of the building leases provided by the CNPC Group to the
     Group, which are lower than the existing annual limit for 2005 due to a
     reduced requirement by the Group, are sufficient for the Group to implement
     future business development and planning.

          We have discussed the basis of the opinion with the Savills (Hong
     Kong) Limited, and have no reason to believe that their opinion is not
     reasonable. We consider that the Proposed Caps are reasonably determined.

     reasonable to the Company and do not exceed the market level. Savills (Hong

     by the Company from CNPC, by adopting "Direct Comparison Approach" by
     making reference to comparable rental evidences as available on the market

          Each of the annual proposed caps comprises of the annual leasing fee
     of RMB2,000 million and the relevant PRC tax of RMB260 million, which are
     in accordance with the Land Use Rights Leasing Contract.

          We have discussed the basis of the opinion with the Savills (Hong
     Kong) Limited, and have no reasons to believe that their opinion is not
     reasonable. We consider that the Proposed Caps are reasonably determined.

     3.11 PRODUCTS AND SERVICES TO BE PROVIDED BY THE GROUP TO CRMSC

          The Proposed Caps for the products and services to be provided by the
     Group to CRMSC, amongst other things, gasoline, diesel and other petroleum
     products, and are determined with reference to:

          (a)  the volatility and possible increase in the price of petroleum
               products;

          (b)  the historical transaction levels for the same type of
               transactions; and

          (c)  the estimated future transaction levels based on estimated market
               need in the coming three years.

          As mentioned in the Circular, the historical revenue in relation to
     the provision of the products and services which are the subject matter of
     CRMSC Products and Services Agreement between the Company and CRMSC was
     RMB4,041 million for the six months ended 30 June 2005. Based on the above
     figure, the annualized figure of the transaction for the year ending 31
     December 2005 is approximately RMB8,082 million. The annual compound growth
     rate of the CRMSC Transactions for the three years ending 31 December 2008
     is therefore a modest 15.6%.

          Considering (i) the business growth of CRMSC; (ii) the fluctuation and
     potential upside in the petroleum products; and (iii) the modest annual
     compound growth rate of the CRMSC Transactions, we are of the opinion that
     Proposed Caps are reasonably determined.
