                    (A Joint Stock Company limited by shares
                incorporated in the People's Republic of China)

                       ONGOING CONNECTED TRANSACTIONS AND
                    ADDITIONAL ONGOING CONNECTED TRANSACTIONS

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 disclosure or if necessary, obtain the Shareholders' approval
for each transaction as it arises. The Stock Exchange, on 26 November 2002,
granted the Existing Waiver to the Company in respect of the Existing Ongoing
Connected Transactions. The Existing Waiver will expire on 31 December 2005. In
addition to the Existing Ongoing Connected Transactions and the Newco Continuing
CT (recently approved by Independent Shareholders at the Recent EGM), the Board
would also like to draw the Shareholders' attention to the Additional Ongoing
Connected Transactions. The Additional Ongoing Connected Transactions,
comprising the Beijing Gas Transactions and the CRMSC Transactions, are the
connected transactions between the Company and certain connected persons other
than CNPC, namely Beijing Gas and CRMSC.

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 the reporting, announcement and Independent
Shareholders' approval (or Shareholders' approval in the case of the CRMSC
Transactions) requirements pursuant to the Listing Rules. The Beijing Gas
Transactions will only be subject to the reporting and announcement requirements
pursuant to the Listing Rules.

THE EGM IS TO BE HELD FOR THE PURPOSE OF CONSIDERING AND, IF DEEMED APPROPRIATE,
APPROVING, AMONG OTHERS, THE ONGOING CONNECTED TRANSACTIONS. A CIRCULAR
CONTAINING PARTICULARS OF THE ONGOING CONNECTED TRANSACTIONS, A LETTER FROM THE
INDEPENDENT BOARD COMMITTEE, A LETTER OF ADVICE FROM ICEA AND A NOTICE TO
CONVENE THE EGM TO APPROVE, AMONG OTHER THINGS, THE ONGOING CONNECTED
TRANSACTIONS WILL BE DISPATCHED TO THE SHAREHOLDERS AS SOON AS PRACTICABLE.








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
      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 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 Additional Ongoing
      Connected Transactions. The Additional Ongoing Connected Transactions are
      the connected transactions between the Group and certain connected persons
      other than CNPC, namely Beijing Gas and CRMSC.

      The Ongoing Connected 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. The Beijing Gas Transactions will only be
      subject to the reporting and announcement requirements pursuant to the
      Listing Rules. Announcement is hereby made in compliance with the relevant
      provisions under the Listing Rules in respect of the Ongoing Connected
      Transactions and the Beijing Gas Transactions.


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 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 announcement.

      (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, training centers and guesthouses; and

            Financial services, including but not limited to loans and deposits
            services.

      (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

            (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.

      (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.

      The following table sets forth the historical revenues and expenditures in
      relation to the provision of the products and services which are the
      subject matters of the Comprehensive Agreement between the Company and

      SECOND SUPPLEMENTAL COMPREHENSIVE AGREEMENT

            relevant units to provide products and services in accordance with
            the terms and principles of the Comprehensive Agreement;

      .     the CNPC Group will provide certain risk operation services as part
            of the construction and technical services to the Group, and these
            include the provision of exploration and production services within
            certain and specific reserves of the Company with exploration and
            exploitation difficulties;

      .     the Group will provide certain financial assistance to the

            and

      Under the Second Supplemental Comprehensive Agreement, the products and

            and

            state-prescribed price and market price.

      The Second Supplemental Comprehensive Agreement will take effect on 1
      January 2006, after the approval by the Independent Shareholders at the
      EGM.


      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 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. The date of valuation is 30 June 2005. ICEA, the
      independent financial adviser to the Independent Board Committee will
      opine, in its advice to be contained in the Company's forthcoming
      circular, on whether it is normal business practice for the Land Use
      Rights Leasing Contract to have a term of 50 years.


      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.


      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. The date of
      valuation is 30 June 2005. ICEA, the independent financial adviser to the
      Independent Board Committee will opine, in its advice to be contained in
      the Company's




      forthcoming circular, on whether it is normal business practice for the
      Buildings Leasing Contract and the Supplemental Buildings Agreement to
      have a term of 20 years.


3.    NEWCO CONTINUING CT

            exploration technology services by CNPC Group to Newco Group;

      ONGOING CONNECTED TRANSACTIONS AND ADDITIONAL ONGOING CONNECTED
      TRANSACTIONS

      CNPC

      As CNPC directly owns an aggregate of approximately 90% of the issued
      share capital of the Company, CNPC is a connected person of the Company
      under the Listing Rules.

      NEWCO

      As Newco will become a non wholly-owned subsidiary of the Company upon the
      completion of the Transactions and CNPC will become a substantial
      shareholder of Newco, Newco will be a connected person of the Company
      under the Listing Rules.



      BEIJING GAS

      As Beijing Gas is a substantial shareholder of the Company's subsidiary,
      Huayou, it is a connected person of the Company under the Listing Rules.

      CRMSC

      CRMSC, being a substantial shareholder of the Company's subsidiary,
      PetroChina & CRMSC Oil Marketing, is a connected person of the Company
      under the Listing Rules.

      Transactions between the Group and connected persons constitute connected
      transactions of the Company under the Listing Rules and are subject to the
      reporting, announcement and/or Independent Shareholders' or Shareholders'
      approval requirements pursuant the Listing Rules.

6.    REASONS FOR AND BENEFITS OF THE ONGOING CONNECTED TRANSACTIONS AND
      ADDITIONAL ONGOING CONNECTED TRANSACTION

      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 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.

      In view of the strengths and scope of CNPC's business activities and the
      strong favourable support that such Ongoing Connected Transactions would
      bring to the Company's business activities, the Board believes that the
      Ongoing Connected Transactions 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 Ongoing Connected Transactions as referred to in this announcement 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 Ongoing Connected Transactions
      with CNPC Group as these transactions have facilitated and will continue
      to facilitate the operation of the Group's business.

      REASONS FOR AND BENEFITS OF THE ONGOING CONNECTED TRANSACTIONS WITH
      BEIJING GAS

      The ongoing connected transactions with Beijing Gas are essential to the
      Company. The Company has strengths in terms of resources. Beijing Gas is
      one of the large operators of natural gas supply network in the PRC. It
      has a dominant position in purchasing and distributing of natural gas in
      the market. In view of the overwhelming economic power and market share of
      Beijing Gas, the combined strengths of the Company and Beijing Gas in
      terms of resources and market share come into play. The ongoing connected
      transactions between the Group and Beijing Gas enhance the competitiveness
      of both the Group and Beijing Gas. With the Company becoming the natural
      gas supplier of Beijing Gas, the Company has found strong and favourable
      support for its operations.

      The ongoing connected transactions with Beijing Gas 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
      Beijing Gas, it is favourable for the Company to expand its market share
      and the Company's development.



      REASONS FOR AND BENEFITS OF THE ONGOING CONNECTED TRANSACTIONS WITH CRMSC

      The ongoing connected transactions with CRMSC 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 ongoing connected transactions with CRMSC 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.

      (C)   The historical revenue in relation to the provision of the products
            and services which are the subject matter of the Beijing Gas
            Products and Services Agreement between the Company and Beijing Gas
            was RMB103 million in the month of July 2005. Beijing Gas only
            became the shareholder of Huayou (and hence a connected person of
            the Company) in June 2005 and there had not been any connected
            transactions between the Company and Beijing Gas before June 2005.
            In relation to the Beijing Gas Products and Services Agreement, the
            total revenue in respect of the relevant products and services will
            be RMB4,939 million, RMB5,983 million and RMB7,097 million for each
            of 2006, 2007 and 2008 respectively. Such 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 Beijing
            Gas became a connected person of the Company; and (iii) the
            estimated future transaction levels based on market needs in the
            coming 3 years. As each of the applicable percentage ratio(s) (other
            than the profits ratio) in respect of this type of connected
            transaction is, on an annual basis, expected to be more than 0.1%
            but less than 2.5%, such type of transaction is only subject to the
            reporting and announcement requirements under the Listing Rules but
            does not require approval by the Independent Shareholders.


      (D)   the Company's annual report and accounts shall contain a statement
            that, in the opinion of the Directors, the arrangement has been
            entered into in the manner as stated in the table above.

            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.

            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, financial
                  advisory and insurance services.

                  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
