THE ACQUISITION On 23 August 2006, the Board announced that CNPC E&D, a subsidiary of PetroChina and a 50 : 50 joint venture between PetroChina and CNODC, entered into the Acquisition Agreement through the Acquirer (a wholly owned subsidiary of CNPC E&D) with the Vendor (a wholly owned subsidiary of CNODC), for the acquisition by the Acquirer of CNODC's entire interest in PetroKazakhstan, representing 67% of the issued share capital of PetroKazakhstan. -4- LETTER FROM THE BOARD The Board believes that the Acquisition represents an important opportunity for PetroChina to further enhance its overseas working interests of oil and gas reserve, to expand PeroChina's overseas exploration and production assets in a strategically important region, to derive synergies from the Kazakhstan-China Pipeline, the Dushanzi Refinery and CNPC E&D's existing Kazakhstan exploration and production operations and to further improve PetroChina's financial performance. CNODC is wholly owned by CNPC, the controlling shareholder of PetroChina. As at the date of this circular, CNPC holds approximately 88.21% of the issued share capital of PetroChina. Pursuant to the Listing Rules, CNODC and the Vendor are connected persons of PetroChina. CNPC E&D is a connected person of PetroChina pursuant to Listing Rule 14A.11(5). Upon the completion of the Acquisition, PetroChina will, through CNPC E&D, hold 67% of PetroKazakhstan. PetroKazakhstan will therefore become a non-wholly owned subsidiary of CNPC E&D and PetroChina and a connected person of PetroChina pursuant to Rule 14A.11(6) of the Listing Rules. The Acquisition constitutes a connected transaction of PetroChina under the Listing Rules. As the relevant percentage ratios involved in the Acquisition are more than 0.1% but less than 2.5% for the Group, the Acquisition is only subject to reporting and announcement requirements and exempted from the independent shareholders' approval requirement under Rule 14A.32 of the Listing Rules. Further details regarding the Acquisition, the Acquisition Agreement and PetroKazakhstan were set out in the Announcement. 2. REVISION OF EXISTING CAPS AND LISTING RULES IMPLICATIONS The Announcement also announced that PetroChina proposes to revise the Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement as previously approved by the Independent Shareholders (or by the Shareholders in respect of the Existing Caps for the CRMSC Transactions) on 8 November 2005. The Proposed Caps, for the three-year period from 1 January 2006 to 31 December 2008, are the result of: - continuing connected transactions arising as a result of the completion of the Acquisition, which will fall within the scope of the Amended Comprehensive Agreement; and - changes to PetroChina's production and operational environment that are expected to have an impact on the Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement, as explained in detail in this circular. The Proposed Caps are subject to reporting, announcement and Independent Shareholders' approval (or Shareholders' approval in respect of the Proposed Caps for the CRMSC Transactions) requirements under the Listing Rules. An Independent Board Committee has been appointed by the Board to consider the Proposed Caps. ICEA Capital Limited has been retained as the Independent Financial Adviser to advise the Independent Board Committee as to whether the Proposed Caps are fair and reasonable so far as the Shareholders are concerned. -5- LETTER FROM THE BOARD 3. THE AMENDED COMPREHENSIVE AGREEMENT The Amended Comprehensive Agreement was entered into by and between CNPC and PetroChina on 10 March 2001, which was further amended on 9 June 2005 and 1 September 2005 respectively. The Amended Comprehensive Agreement is valid for three years, commencing from 1 January 2006. Detailed information about the terms and conditions of the Amended Comprehensive Agreement, including but not limited to general principles, price and terms, price determination, coordination of annual demand of products and services, rights and obligations, term and termination and the annual caps in respect of the transactions under the Amended Comprehensive Agreement were disclosed in the circular to the Shareholders dated 22 September 2005 and were approved by the Independent Shareholders at the extraordinary general meeting held on 8 November 2005. The Amended Comprehensive Agreement applies to connected transactions between the CNPC Group (including Jointly-owned Companies) and the Group. Pursuant to the Amended Comprehensive Agreement, a Jointly-owned Company means a company in which both PetroChina and the CNPC Group are shareholders, and where the CNPC Group and/or its subsidiaries and/or affiliates (individually or together) is/are entitled to exercise, or control the exercise of, 10% or more of the voting power at any general meeting of such company. As explained in the Announcement, PetroKazakhstan will be equity-accounted for in PetroChina's consolidated financial statements since PetroChina and KMG are considered as having joint control over PetroKazakhstan. At the same time, PetroKazakhstan will be treated as a "subsidiary" of PetroChina for the purposes of the Listing Rules because, among other things, PetroChina will hold more than half of the issued share capital of PetroKazakhstan. Accordingly, upon the completion of the Acquisition, PetroKazakhstan will become a non-wholly owned subsidiary of PetroChina. It will also become a connected person of PetroChina pursuant to Rule 14A.11(6) of the Listing Rules as well as a Jointly-owned Company as defined by the Amended Comprehensive Agreement. Given that PetroKazakhstan will be a subsidiary of PetroChina held through CNPC E&D, connected transactions involving the PetroKazakhstan Group will be treated in the same manner as transactions involving CNPC E&D and its subsidiaries, which were approved by the Independent Shareholders on 8 November 2005. On this basis, PetroChina has classified connected transactions between the PetroKazakhstan Group and the Group as transactions between the CNPC Group (including Jointly-owned Companies) and the Group, and connected transactions between the PetroKazakhstan Group and the CNPC Group as transactions between the Group and the CNPC Group. 4. THE CRMSC PRODUCTS AND SERVICES AGREEMENT On 1 September 2005, PetroChina entered into the CRMSC Products and Services Agreement with CRMSC, pursuant to which PetroChina should provide CRMSC with products and services including, among other things, refined products (such as gasoline, diesel and other petroleum products) on an ongoing basis. CRMSC, being a substantial shareholder of PetroChina's subsidiary, PetroChina & CRMSC Oil Marketing, is a connected person of PetroChina pursuant to the Listing Rules. Detailed information regarding the terms and conditions of the CRMSC Products and Services Agreement and the annual caps in respect of CRMSC Transactions were disclosed in the circular to the Shareholders dated 22 September 2005 and were approved by the Shareholders at the extraordinary general meeting held on 8 November 2005. -6- LETTER FROM THE BOARD 5. PROPOSED CAPS (a) Revision due to continuing connected transactions arising as a result of the Acquisition (i) Production services to be provided by the CNPC Group to the Group The Amended Comprehensive Agreement provides that the CNPC Group (including Jointly-owned Companies such as PetroKazakhkstan) shall supply crude oil, refined oil, chemical products, natural gas and production services (including transportation) to the Group at the government-prescribed price. Where there is no government-prescribed price but market price is available, the price shall be determined with reference to the market price. The Board has considered and proposed the following increases to the Existing Caps in respect of this category of transaction. Such increases are attributable to the Group's proposed purchase of crude oil from the PetroKazakhstan Group and transportation of such crude oil via the Kazakhstan-China Pipeline and the Western Pipeline in accordance with the Amended Comprehensive Agreement. Proposed increase to the Existing Caps (RMB in millions) ------------------------ Category of Products and Services 2006 2007 2008 --------------------------------- ------ ------ ------ Production services to be provided by the CNPC Group to the Group 13,040 36,000 34,720 The above proposed increases to the Existing Caps have been determined with reference to the following: the estimated growth in crude oil production and business of the PetroKazakhstan Group; current market prices of crude oil; potential fluctuations and increases in the prices of crude oil both in the international market and in the domestic market; the estimated annual crude oil volume to be purchased by the Group from the PetroKazakhstan Group; the transportation capacities of the Kazakhstan-China Pipeline and the Western Pipeline; and charges of the Kazakhstan-China Pipeline and the Western Pipeline for oil transportation and the potential fluctuations and increases in such charges. The significant increases of transaction amount in 2007 and 2008 are due to the increases of the Kazakhstan-China Pipeline's transportation capacity, which is 3.5 million tonnes in 2006 and expected to be 10 million tonnes in 2007 and 2008 when its construction is fully completed. (ii) Construction and technical services to be provided by the CNPC Group to the Group. Prior to the Acquisition, the Group has obtained construction and technical services from the CNPC Group. Given that the construction and technical services provided to the Group by the CNPC Group are of a high quality and on favourable pricing terms, the Group (including the PetroKazakhstan Group) will continue to obtain construction and technical services from the CNPC Group after the Acquisition. The Board has considered and proposed the following increases to the Existing Caps in respect of this category of transaction. Such increases are attributable to the provision of services by the CNPC Group to the PetroKazakhstan Group, including but not limited to geophysical prospecting, well drilling, logging, well testing, down-hole operations, oilfield surface facilities construction, construction design and construction supervision. This category of transaction will be charged on actual cost incurred basis. -7- LETTER FROM THE BOARD Proposed increases to the Existing Caps (RMB in millions) --------------------- Category of Products and Services 2006 2007 2008 --------------------------------- ----- ----- ----- Construction and technical services to be provided by the CNPC Group to the Group 1,880 1,800 1,640 The above proposed increases to the Existing Caps have been determined with reference to the following: historical transaction price and transaction amounts for the construction and technical services of the PetroKazakhstan Group; and the estimated business growth of the PetroKazakhstan Group. (iii) Material supply services to be provided by the CNPC Group to the Group Prior to the Acquisition, the Group has obtained material supply services from the CNPC Group.

This category of transaction will be charged on actual cost incurred basis. The Board has considered and proposed the following increases to the Existing Caps in respect of this category of transaction. Such increases are attributable to the provision of casing pipes, drill heads, drilling liquid and lubricating oil and other raw materials or equipment by the CNPC Group to the PetroKazakhstan Group. Proposed increases to the Existing Caps (RMB in millions) ------------------ Category of Products and Services 2006 2007 2008 --------------------------------- ---- ---- ---- Material supply services to be provided by the CNPC Group to the Group 240 480 480 The above proposed increases to the Existing Caps have been determined with reference to the following: historical transaction prices and transaction amounts in respect of material supply transactions of the PetroKazakhstan Group; estimated business growth of the PetroKazakhstan Group; and estimated changes in the volume of purchases by the PetroKazakhstan Group. (b) Revision due to changes to PetroChina's production and operational environment (i) Products and services to be provided by the Group to the CNPC Group The Amended Comprehensive Agreement provides that the Group shall provide products such as natural gas, crude oil and refined oil to the CNPC Group at the government-prescribed price, or where there is no government-prescribed price, the price shall be determined with reference to the market price. -8- LETTER FROM THE BOARD The reasons for applying for increases to the Existing Caps of this transaction are: - Natural gas Natural gas is sold at government-prescribed price in the PRC. The National Development and Reform Commission issued the Notice on the Reform of the Mechanism for Determining the Ex-Factory Prices of Natural Gas and Recent Appropriate Increase of the Ex-Factory Prices of Natural Gas on 23 December 2005, which made adjustments to the pricing mechanism and the ex-factory price of natural gas. Pursuant to the notice, the ex-factory price of natural gas was increased from 26 December 2005. The notice also indicated that the PRC government would increase the price of natural gas in the next five years and would establish a system to link the price of natural gas to the price of substitution products including crude oil, liquefied petroleum gas and coal. - Refined oil Refined oil is sold at government-prescribed price in the PRC. In the first half of 2006, the National Development and Reform Commission has issued two notices on the adjustments to the prices of refined oil, which increased the ex-factory prices of refined oil on 26 March and 24 May 2006 respectively. - Crude oil Currently, the crude oil prices on the domestic market of the PRC are adjusted with reference to the crude oil prices on the international market. As there has been a substantial increase in the crude oil price on the international market recently, the increase with respect to domestic crude oil price has jumped well above its level as at 8 November 2005 when Independent Shareholders' approval for the Existing Caps was sought. - Nephtha, solvent oil The Ministry of Finance and the State Administration of Taxation issued the Notice on Adjustments and Perfection of the Policy on Consumer Taxes on 20 March 2006, which imposes consumer tax on naphtha, solvent oil and other products, and the costs of raw materials for chemical products have increased as a result. - Transaction amount As a result of business development, there is an increase of the amount of transactions between the Group and the CNPC Group as compared with the amount of 8 November 2005 when Independent Shareholders' approval for the Existing Caps was sought. -9- LETTER FROM THE BOARD The table below sets out the monthly average prices of natural gas, refined oil, crude oil, naphtha and solvent oil of PetroChina for April 2005 (when PetroChina performed its estimates for the Existing Caps), September 2005 (when PetroChina announced and applied for the Shareholders' approval on the Existing Caps) and July 2006 : Monthly Average Prices % increase % increase than than Products April 05 September 05 July 06 April 05 September 05 -------- -------- ------------ ------- ---------- ------------ (RMB Yuan/Ton) Natural Gas 585 585 690 17.95% 17.95% Refined Oil Gasoline 3,277 4,062 4,800 46.48% 18.18% Jet fuel 3,160 4,375 5,114 61.81% 16.88% Diesel Oil 2,864 3,573 4,219 47.33% 18.09% Crude Oil 2,332 3,616 4,056 73.59% 12.17% Nephtha 2,396 3,844 4,657 94.40% 21.17% Solvent oil 3,369 4,308 4,631 37.45% 7.5% Due to the above reasons, the Board has considered and proposed the following increases to the Existing Caps in respect of this category of transaction. Proposed increases to the Existing Caps (RMB in millions) ------------------------ Category of Products and Services 2006 2007 2008 --------------------------------- ------ ------ ------ Products and services to be provided by the Group to the CNPC Group 17,536 21,498 23,219 The above proposed increases to the Existing Caps have been determined with reference to the following: historical transaction records for products and services provided by the Group to the CNPC Group; the actual and estimated increases to the price of relevant products; and the actual and estimated business growth of the Group and the CNPC Group. (ii) Products and services to be provided by the CNPC Group to the Group (a) Production services The proposed increases to the Existing Caps of this category of transaction are mainly attributable to the fact that due to the PRC's increasing demand on crude oil, the Group intends to purchase crude oil from CNPC E&D and its subsidiaries in addition to the crude oil from the PetroKazakhstan Group as set out in section 5 (a) (i) of this circular. Other production services consist of water supply, electricity generation and supply, gas supply, transportation, etc. by the CNPC Group to the Group. Such increases are attributable to the formal commencement of operation of the Kazakhstan-China Pipeline and the Western Pipeline in the near future and the internal integration of the CNPC Group, which will increase its delivery capacity in the refined oil retail market in the PRC, thus creating more opportunities of refined oil delivery business for the Group. The Board has considered and proposed the following increases to the Existing Caps in respect of this category of transaction. -10- LETTER FROM THE BOARD Proposed increases to the Existing Caps (RMB in millions) ------------------------ Category of Products and Services 2006 2007 2008 --------------------------------- ------ ------ ------ Production services to be provided by the CNPC Group to the Group 23,430 31,514 31,151 The above proposed increases have been determined with reference to the following: historical transaction records for the production services provided by the CNPC Group to the Group; medium and long term development plan of the Group; the actual and estimated business growth of the Group; and the potential increase in the international and domestic market prices of crude oil, petroleum and other petrochemical products.

(iii) Products and services to be provided by the Group to CRMSC On 1 September 2005, PetroChina entered into the CRMSC Products and Services Agreement with CRMSC, pursuant to which PetroChina should provide CRMSC with products and services including, among other things, refined products (such as gasoline, diesel and other petroleum products) on an ongoing basis.

(ICEA LOGO) (Chinese Characters) A subsidiary of ICBC (Chinese Characters) ICEA CAPITAL LIMITED (Chinese Characters) 26/F., ICBC Tower (Chinese Characters) 3 Garden Road, Central, Hong Kong (Chinese Characters) General Line: (852) 2231 8000 (Chinese Characters) General Fax: (852) 2525 0967 (Chinese Characters) 14 September 2006 To the Independent Board Committee and the Shareholders Dear Sirs, REVISION OF EXISTING CAPS We refer to our engagement as the Independent Financial Adviser to advise the Independent Board Committee and the Independent Shareholders (or the Shareholders for CRMSC Transactions) on the fair and reasonableness of the Proposed Caps for each of the three years ending 31 December 2006, 2007 and 2008. Pursuant to the Listing Rules, the Proposed Caps are subject to, among other things, the approval of the Independent Shareholders (or the approval of the Shareholders for the CRMSC Transactions) at a general meeting of PetroChina Company Limited ("Petrochina"). Details of the Proposed Caps are summarized in PetroChina's circular to its Shareholders dated 14 September 2006 (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. On 23 August 2006, PetroChina announced that CNPC E&D, a subsidiary of PetroChina and a 50 : 50 joint venture between PetroChina and CNODC, entered into the Acquisition Agreement through the Acquirer (a wholly owned subsidiary of CNPC E&D) with the Vendor (a wholly owned subsidiary of CNODC), for the acquisition by the Acquirer of CNODC's entire interest in PetroKazakhstan, representing 67% of the issued share capital of PetroKazakhstan. Please refer to the announcement of PetroChina dated 23 August 2006 and "Letter from the Board" in this Circular for details of the Acquisition. As a result of (i) the completion of the Acquisition, certain continuing connected transactions which will fall within the scope of the Amended Comprehensive Agreement will arise; and (ii) changes to PetroChina's production and operational environment that are expected to have an impact on the Existing Caps, PetroChina proposes to revise the Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement as previously approved by the Independent Shareholders (or by the Shareholders for the CRMSC Transactions) on 8 November 2005. The Proposed Caps for the three years ending 31 December 2008 are subject to reporting, announcement and independent shareholders' approval requirements under the Listing Rules. Our opinion only applies to the Proposed Caps subject to Independent Shareholders' approval (or the Shareholders' approval for the CRMSC Transactions). All other connected transactions, continuing connected transactions and their respective caps that are not subject to independent shareholders' approval under the Listing Rules are not within the scope of our work. -17- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER We, ICEA Capital Limited, have been retained as the Independent Financial Adviser to advise the Independent Board Committee and the Independent Shareholders (or Shareholders for the CRMSC Transactions) as to whether the Proposed Caps are fair and reasonable so far as the Independent Shareholders (or Shareholders for the CRMSC Transactions) are concerned. In formulating our recommendation, we have relied, without assuming any responsibility for independent verification, on the information, opinions and facts supplied and representations made to us by the Directors, who have assumed full responsibility for the accuracy of the information contained in the Circular, and that any information and representations made to us are true, accurate and complete in all material respects as at the date hereof and that they may be relied upon. We have no reason to doubt the truth, accuracy and completeness of the information and representation provided to us by PetroChina. We have discussed with the management of PetroChina regarding their plans and prospects of PetroChina. We have also relied on certain information available to the public and have assumed such information to be accurate and reliable, and we have not independently verified the accuracy of such information. We have studied the relevant market and other conditions and trends relevant to the Proposed Caps. We have also assumed that statements and representations made or referred to in the Circular were accurate at the time they were made and continue to be accurate at the date of the Circular. We consider that we have reviewed sufficient information to reach an informed view in order to provide a reasonable basis for our advice. We have not, however, carried out any independent verification of the information provided to us nor have we conducted any form of in-depth investigation into the business affairs or assets and liabilities of PetroChina, the CNPC Group, PetroKazakhstan or any of their respective subsidiaries or associated companies. Additionally, we did not conduct any physical inspection of the properties or facilities of PetroChina, the CNPC Group, PetroKazakhstan or any of their respective subsidiaries or associated companies. It is not within our terms of engagement to comment on the commercial feasibility of the continuing connected transactions, which remains the responsibility of the Directors. As the Independent Financial Adviser to the Independent Board Committee and the Independent Shareholders (or to the Shareholders for CRMSC Transactions), we have not been involved in the negotiations in respect of the terms of the continuing connected transactions and the determination of the Proposed Caps. Our opinion has been made on the assumption that all obligations to be performed by each of the parties to the continuing connected transactions will be fully performed in accordance with the terms thereof. Our opinion is necessarily based upon the financial, economic, market, regulatory, and other conditions as they exist on, and the facts, information, and opinions made available to us as of the date of this letter.

PRINCIPAL FACTORS CONSIDERED In arriving at our opinion, we have taken into consideration the principal factors and reasons set out below. In reaching our conclusion, we have considered the results of the analyses in light of each other and ultimately reached our opinion based on the results of all analyses taken as a whole. -18- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER 1. Background of the continuing connected transactions under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement The Amended Comprehensive Agreement was initially entered into between PetroChina and CNPC on 10 March 2001, which was amended on 9 June 2005 and 1 September 2005 respectively. On 1 September 2005, PetroChina and CRMSC entered into the CRMSC Products and Services Agreement. Detailed information about the terms and conditions of the continuing connected transactions under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement were disclosed in the circular of PetroChina to the Shareholders dated 22 September 2005. 2. Reasons for revision of the Existing Caps As stated in the Letter from the Board in the Circular, PetroChina proposes to revise the Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement as previously approved by the then Independent Shareholders (or by the then Shareholders for the CRMSC Transactions) on 8 November 2005. The revision of the Existing Caps to the Proposed Caps for the three years ending 31 December 2006, 2007 and 2008 are the result of: (i) continuing connected transactions arising as a result of the completion of the Acquisition, which will fall within the scope of the Amended Comprehensive Agreement; and (ii) changes to PetroChina's production and operational environment that are expected to have an impact on the Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products and Services Agreement. 3. Revision of the Existing Caps 3.1 Revision due to the continuing connected transactions arising as a result of the Acquisition Given the business size of the PetroKazakhstan Group and the fact that the transactions between the PetroKazakhstan Group and the CNPC Group will fall within the scope of the Amended Comprehensive Agreement upon completion of the Acquisition, we considered that revision of the Existing Caps to the Proposed Caps is fair and reasonable and in the interest of PetroChina and the Shareholders. The proposed increases to the Existing Caps as a result of the Acquisition are summarized as follows: Proposed increases to the Existing Caps ------------------------ Category of Products and Services 2006 2007 2008 --------------------------------- ------ ------ ------ (RMB in millions) 3.1.1 Production services to be provided by the CNPC Group to the Group 13,040 36,000 34,720 3.1.2 Construction and technical services to be provided by the CNPC Group to the Group 1,880 1,800 1,640 3.1.3 Material supply services to be provided by the CNPC Group to the Group 240 480 480 -19- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER 3.1.1 Production services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for the products and services to be provided by the CNPC Group to the Group have been determined with reference to: (i) the estimated growth in crude oil production and business of the PetroKazakhstan Group; (ii) current market prices of crude oil; (iii) potential fluctuations and increases in the prices of crude oil both in the international market and in the domestic market; (iv) the estimated annual crude oil volume to be purchased by the Group from the PetroKazakhstan Group; (v) the transportation capacities of the Kazakhstan-China Pipeline and the Western Pipeline; and (vi) charges of the Kazakhstan-China Pipeline and the Western Pipeline for oil transportation and the potential fluctuations and increases in such charges. The proposed increases to the Existing Caps for the production services to be provided by the CNPC Group to the Group for the three years ending 31 December 2006, 2007 and 2008 are mainly due to the proposed purchase of the crude oil from the PetroKazakhstan Group and transportation of such crude oil through the Kazakhstan-China Pipeline and the Western Pipeline in accordance with the Amended Comprehensive Agreement as a result of the Acquisition. Part of the Kazakhstan-China Pipeline and the Western Pipeline has been put into service in 2006. Based on the information provided by PetroChina, the Group plans to purchase 3.5 million tons, 10 million tons and 10 million tons of crude oil from the PetroKazakhstan Group for 2006, 2007 and 2008 respectively. The proposed increases in transaction amounts are estimated based on the transportation capacity of the two pipelines, the business development of the Group, the current crude oil market and the estimated commodity price of crude oil price with reference to the average Brent crude oil future price of approximately US$64.7 per barrel in early 2006 as quoted in Bloomberg. In light of the above and taken into consideration of (i) the discussion with the management of PetroChina on the business plan of the PetroKazakhstan Group, including its estimated growth in crude oil production and the expected time frame for the full-scale operation of the Kazakhstan-China Pipeline and the Western Pipeline; and (ii) the continuing business growth of the Group as well as the anticipated increase in future crude oil price (both internationally and domestically), we are of the view that the proposed purchase price used in estimating the proposed caps is reasonable and the proposed increases to the Existing Caps for this type of transactions are fairly and reasonably determined. -20- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER 3.1.2 Construction and technical services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for construction and technical services to be provided by the CNPC Group to the Group have been determined with reference to: (i) the historical transactions and transaction amounts for the construction and technical services of the PetroKazakhstan Group; and (ii) the estimated business growth of the PetroKazakhstan Group. After the Acquisition, the PetroKazakhstan Group will expedite its development and increase capital expenditure in the next three years. As stated in the Letter from the Board of this Circular, given that the construction and technical services provided to the Group by the CNPC Group are of a high quality and on favourable in pricing term, the Group (including the PetroKazakhstan Group) will continue to obtain construction and technical services from the CNPC Group after the Acquisition. We have discussed with the management of PetroChina on the future capital expenditure plan of PetroKazakhstan and have reviewed the relevant documents and information (in particular, the historical transactions and transaction amounts), and considered the plan was prepared after due and careful enquiry. As such, we are of the view that the proposed increases to the Existing Caps for this type of services are determined on a fair and reasonable basis and are sufficient for the Group to capture the future anticipated expansion plan of the PetroKazakhstan Group. 3.1.3 Material supply services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for material supply services to be provided by the CNPC Group to the Group have been determined with reference to: (i) historical prices and transaction amounts in respect of material supply transactions of the PetroKazakhstan Group; (ii) estimated business growth of the PetroKazakhstan Group; and (iii) estimated changes in the volume of purchases by the PetroKazakhstan Group. The proposed increases are mainly attributable to the provision of casing pipes, drill heads, drilling liquid and lubricating oil and other raw materials or equipment by the CNPC Group to the PetroKazakhstan Group for its ordinary daily operation. We understand from the management of PetroChina that the CNPC Group and other independent international suppliers will be invited to tender for the provision of material supply services to the PetroKazakhstan Group. However, based on their past experience, the CNPC Group has competitive advantage over other suppliers on the quality and the price of the services. The proposed increases to the Existing Caps for this type of transactions are based on the potential demand for the materials and equipment of the PetroKazakhstan Group in accordance with its business development plan as well as the estimated cost incurred with the related materials and equipment. Based on (i) the discussion with the management of PetroChina on the future plan of the PetroKazakhstan Group and the possibility for the CNPC Group to obtain contracts for provision of material supply services to the PetroKazakhstan Group; and (ii) the -21- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER review on the relevant documents and information (in particular, the historical transactions and transaction amounts), we are of the view that the proposed increases to the Existing Caps are determined on a fair and reasonable basis. 3.2 Revision due to changes to PetroChina's production and operational environment Proposed increases to the Existing Caps --------------------------------------- Category of Products and Services 2006 2007 2008 --------------------------------- ------ ------ ------ (RMB in millions) 3.2.1 Products and services to be provided by the CNPC Group to the Group (a) Production services to be provided by the CNPC Group to the Group 23,430 31,514 31,151 (b) Construction and technical services to be provided by the CNPC Group to the Group 21,187 24,959 24,385 (c) Material supply services to be provided by the CNPC Group to the Group 646 649 595 3.2.2 Products and services to be provided by the Group to the CNPC Group 17,536 21,498 23,219 3.2.3 Products and services to be provided by the Group to CRMSC 722 666 658 3.2.1 Products and services to be provided by the CNPC Group to the Group (a) Production services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for the production services to be provided by the CNPC Group to the Group have been determined with reference to: (i) historical transaction records for the production services provided by the CNPC Group to the Group; (ii) the medium and long term development plan of the Group; (iii) the actual and estimated business growth of the Group; and (iv) the potential increase in the international and domestic market prices of crude oil, petroleum and other petrochemical products. Being a major producer and supplier of crude oil in the PRC, PetroChina has the responsibilities on satisfying the national energy demands. In this connection, part of the crude oil from CNPC E&D will be send back to the Group in the PRC for refining and processing, and sold in the domestic market. Approximately 5% of the crude oil production of CNPC E&D in 2005 was sent back to the domestic market through PetroChina following the completion of PetroChina's acquisition of interest in CNPC E&D in November 2005. -22- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER Since CNPC E&D is expected to speed up its business expansion in the international market in the near future, PetroChina believed that more crude oil will be sold from CNPC E&D to the Group in order to meet the strong domestic demand in the next years. In addition, we understand from the management of PetroChina that (i) the full-scale operation of Kazakhstan-China Pipeline and Western Pipeline is expected to be commenced in 2007, which is earlier than previously expected in September 2005; and (ii) following the internal integration beginning from June 2005, the CNPC Group has established an advanced transportation company which is equipped with modern machines for petroleum and other petrochemical products and able to provide transportation services with higher efficiency and quality and competitive advantage on the quality and price of such services. In view of the above, the management of PetroChina considered that there will be increased opportunities of refined oil delivery business for the Group than that as anticipated in September 2005, and hence, increasing the other production services to be provided by the CNPC Group to the Group such as water supply, electricity generation and supply, gas supply and transportation. We also noted that the actual transaction amount for the production services provided by the CNPC Group to the Group for the first six months ended 30 June 2005 was approximately RMB8,945 million, representing approximately 38.3% of the total transaction amount of the whole year of 2005. Based on the information of PetroChina, the actual transaction amount for the same type of services for the first six months ended 30 June 2006 was approximately RMB17,058 million, representing approximately 62.0% of the Existing Cap for 2006 and approximately 33.5% of the Proposed Cap for 2006. Production services to be provided by the CNPC Group to the Group Percentage of amount Actual amount for Actual amount/cap for first six months to first six months for the whole year that for whole year ----------------- ------------------ ----------------------- (RMB in millions) (RMB in millions) 2005 8,945 23,344 38.3% 2006 17,058 27,513 62.0% (Existing Cap) 50,943 33.5% (Proposed Cap) (Note) Note: The figure includes the Existing Cap and the proposed increase due to the effect of the changes to the operational environment, and excludes the proposed increase arising as a result of the Acquisition as refer in paragraph 3.1.1 above. Given the increasing demand of crude oil from CNPC E&D, the increased opportunities of refined oil delivery business for the Group and that the proposed caps are in line with the historical data, we consider the revision of the Existing Caps is fair and reasonable so far as the Group and Shareholders concerned and the Proposed Caps have been determined on a fair and reasonable basis. -23- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER (b) Construction and technical services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for the construction and technical services to be provided by the CNPC Group to the Group have been determined with reference to: (i) historical transaction records for the construction and technical services provided by the CNPC Group to the Group; (ii) the medium and long term development plan of the Group; (iii) the actual and the estimated business growth of the Group; (iv) the increases of prices of relevant oil products; and (v) the estimated relevant service price. The construction and technical services to be provided by the CNPC Group to the Group are mainly related to development of oilfields, including but not limited to exploration technology service, down hole operation service, oilfield construction service, oil refinery construction service and project supervision and design service. We understand from the management of PetroChina that after Existing Caps were determined in 2005, there has been important oil exploration discovery on three major oilfields of PetroChina (including Ji Dong oilfields). Accordingly, PetroChina plans to substantially increase its capital and expenditure budget in the three years ending 31 December 2006, 2007 and 2008 to cater for the development of such oilfields. Even assuming that there was no breakthrough in oil exploration discovery on such oilfields and they were developed as originally planned, the overall transaction amount of the construction and technical services of the Group for the three years ending 31 December 2008 is expected to rise because of the increase of the crude oil price since last September. According to Platts, the world's leading provider of energy information, the Minas Crude Oil price as quoted in Singapore Market was around US$60.5 per barrel in September 2005 when the Existing Caps were estimated and reached as high as US$74.1 per barrel in July 2006. Since certain amount of oil products (such as gasoline and diesel oil) will be consumed to generate power during the course of providing the construction and technical services (such as well drilling) to the Group, the increase in the crude oil price is expected to substantially increase the operational cost for construction and technical service providers. Based on the information provided by PetroChina, we noted that approximately 256,000 tons and 1,379,000 tons of gasoline and diesel oil are expected to be consumed respectively in connection with the provision of the construction and technical service in 2006. Despite the construction and technical services for development of such oilfields will be put out to tender, it is likely that the CNPC Group would win the bid and provide such services to the Group because of the large production capability and competitive strengths of the CNPC Group on the oil construction and technical services industry. Given the breakthrough in the oil exploration on some oilfield of PetroChina and the substantial increase in development costs because of the increase in crude oil price since last September, we are of the view that the revision of the Existing Caps for this type of -24- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER services is in the interest of PetroChina so to capture the future anticipated business expansion and the respective Proposed Caps have been determined on a fair and reasonable basis. (c) Material supply services to be provided by the CNPC Group to the Group The proposed increases to the Existing Caps for the material supply services to be provided by the CNPC Group to the Group have been determined with reference to: (i) historical transaction records for the supply of materials services provided by the CNPC Group to the Group; (ii) the medium and long term development plan of the Group; (iii) the actual and the estimated business growth of the Group; and (iv) the actual and estimated prices of relevant materials. Pursuant to the Amended Comprehensive Agreement, the Group obtains material supply services from the CNPC Group. Such material supply services are mainly for facilitating the daily operation of the Group, including but not limited to purchase of materials, quality control, storage of materials and delivery of materials. As such, the transaction amounts of this type of services proportionate to the scale of PetroChina's production and operation. Given the unexpected expansion of the business of PetroChina in the near future as analyzed in above paragraphs (a) and (b), we are of the view that revision of the Existing Caps is necessary and the proposed increases to the Existing Caps for this type of services are determined on a fair and reasonable basis. 3.2.2 Products and services to be provided by the Group to the CNPC Group The proposed increases to the Existing Caps for the products and services to be provided by the Group to the CNPC Group have been determined with reference to: (i) historical transaction records for products and services provided by the Group to the CNPC Group; (ii) the actual and estimated increases to the price of relevant products; and (iii) the actual and estimated business growth of the Group and the CNPC Group. The Amended Comprehensive Agreement provides that the Group should supply products such as natural gas, crude oil and refined oil and other products to the CNPC Group at the government-prescribed price, or where there is no government-prescribed price, the price shall be determined with reference to the market price. However, as explained in the Letter from the Board in this Circular, since the approval of the Existing Caps in 2005, the prices of certain major oil products to be supplied by the Group to the CNPC Group has substantially increased. -25- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER - Natural Gas Pursuant to the Notice on the Reform of the Mechanism for Determining the Ex- Factory Prices of Natural Gas and Recent Appropriate Increase of the Ex-Factory Prices of Natural Gas issued by the National Development and Reform Commission on 23 December 2005, the government-prescribed ex-factory price of natural gas increased by approximately 17.95% since 26 December 2005 and the PRC government plans to increase the price of natural gas in the next five years. - Refined oil The National Development and Reform Commission has issued two notices on the adjustment to the prices of refined oil on 26 March 2006 and 24 May 2006. Pursuant to the two notices, the government-prescribed ex-factory prices of refined oil have increased by approximately 52%. - Crude oil Currently, the crude oil prices in the domestic market of the PRC are in line with the crude oil prices in the international market. As stated above, the Minas Crude Oil price as quoted in Singapore Market was US$60.5 per barrel in September 2005 when the Existing Caps were estimated and reached as high as US$74.1 per barrel in July 2006. - Naphtha, solvent oil Pursuant to the Notice on Adjustments and Perfection of the Policy on Consumer Taxes issued by the Ministry of Finance and the State Administration of Taxation on 20 March 2006, consumer tax is imposed on naphtha, solvent oil, and other products since 1 April 2006, increasing the costs of raw materials for chemical products. In addition, PetroChina's middle and long term development goal has been adjusted with respect to the chemicals and marketing segment and refining and marketing segment to further increase its production capacity of these segments. With the anticipated increase in its production capacity, increasing demands for products and services as well as the enlarged business scale and new business development of the CNPC Group, PetroChina is able to supply more products and services to the CNPC Group. We noted that based on the information provided by PetroChina, the actual transaction amount for the products and services provided by the Group to the CNPC Group for the first half of 2005 was approximately RMB6,932 million, representing approximately 35.0% of the total transaction amount for the whole year 2005. However, the actual transaction amount of the first half of 2006 was approximately RMB13,447 million, representing approximately 70.3% of the Existing Cap for 2006 and approximately 36.7% of the Proposed Cap for 2006. -26- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER Products and services to be provided by the Group to the CNPC Group Percentage of amount Actual amount for Actual amount/cap for first six months to first six months for the whole year that for whole year ----------------- ------------------ ----------------------- (RMB in millions) (RMB in millions) 2005 6,932 19,823 35.0% 2006 13,447 19,134 70.3% (Existing Cap) 36,670 36.7% (Proposed Cap) (Note) Note: The figure includes the Existing Cap and the proposed increase due to the effect of the changes to the operational environment of the Group. In light of the above and given that the unexpected business expansion of the Group as well as the anticipated increase in the prices for oil products, we are of the view that the revision of the Existing Cap for this type of services is fair and reasonable and the proposed increases to the Existing Caps are determined on a fair and reasonable basis. 3.2.3 Products and services to be provided by the Group to CRMSC The proposed increases to the Exiting Caps for products and services to be provided by the Group to CRMSC have been determined with reference to: (i) the Group's historical transaction records with CRMSC; (ii) the estimated business growth of the Group and CRMSC; and (iii) the actual and estimated price of refined oil. PetroChina entered into the CRMSC Products and Services Agreement with CRMSC on 1 September 2005, pursuant to which PetroChina should provide CRMSC with products and services including, among other things, refined products (such as gasoline, diesel and other petroleum products) on a continuing basis. Detailed information about the terms and conditions of the CRMSC Products and Services Agreement was disclosed in the circular of PetroChina to the Shareholders dated 22 September 2005. We understand from the management of PetroChina that the supply of refined products to CRMSC constituted a substantial proportion of the CRMSC Transactions. In view that the government-prescribed price of refined oil in the PRC has increased, we consider that the revision of the Existing Cap for this type of services is in the interest of PetroChina and the Shareholders as a whole and the proposed increases to the Existing Caps are fairly and reasonably determined. -27- LETTER FROM THE INDEPENDENT FINANCIAL ADVISER 3.3 Proposed Caps Set out below is a summary of the Existing Caps and the Proposed Caps for each of the three years ending 31 December 2008 : 2006 2007 2008 ------------------- ------------------- ------------------- Category Existing Proposed Existing Proposed Existing Proposed of Products and Services Caps Caps Caps Caps Caps Caps ------------------------ -------- -------- -------- -------- -------- -------- (RMB in millions) (i) Production services to be 27,513 63,983 28,923 96,437 32,647 98,518 provided by the CNPC (Note 1) (Note 1) (Note 1) Group to the Group (ii) Construction and 91,614 114,681 88,280 115,039 79,636 105,661 technical services to be (Note 2) (Note 2) (Note 2) provided by the CNPC Group to the Group (iii) Material supply services 4,471 5,356 4,331 5,459 4,500 5,574 to be provided by the (Note 3) (Note 3) (Note 3) CNPC Group to the Group (iv) Products and services to 19,134 36,670 23,472 44,970 26,910 50,129 be provided by the Group (Note 4) (Note 4) (Note 4) to the CNPC Group (v) Products and services to 10,326 11,048 11,359 12,025 12,495 13,152 be provided by the Group (Note 5) (Note 5) (Note 5) to CRMSC Notes: 1.

Annual review of non-exempted continuing connected transactions As discussed with PetroChina, it will comply with the annual review requirements of the Stock Exchange, in particular: (i) Each year the independent non-executive Directors must review the continuing connected transactions and confirm in the annual report that the transactions have been entered into: - in the ordinary and usual course of business of PetroChina; - either on normal commercial terms or, if there are not sufficient comparable transactions to judge whether they are on normal commercial terms, on terms no less favourable to PetroChina than terms available to or from (as appropriate) independent third parties; and - in accordance with the relevant agreement governing them on terms that are fair and reasonable and in the interests of the Shareholders as a whole; and (ii) Each year the auditors must provide a letter to the Directors (with a copy provided to the Stock Exchange at least 10 business days prior to the bulk printing of PetroChina's annual report), confirming that the continuing connected transactions: - have received the approval of the Directors; - are in accordance with the pricing policies of PetroChina if the transactions involve provision of goods or services by PetroChina; - have been entered into in accordance with the relevant agreement governing the transactions; and - have not exceeded the caps approved by the Independent Shareholders (or by the Shareholders for CRMSC Transactions) and disclosed in previous announcement(s). Based on the above, we are of the view that there are appropriate measures in place to monitor the non-exempted continuing connected transactions and protect the interest of PetroChina and the Shareholders as a whole. RECOMMENDATION Having considered the above principal factors and reasons, we consider that the revision of the Existing Caps is in the interest of PetroChina and the Shareholders as a whole, and the Proposed Caps are determined on a fair and reasonable basis and are in the interest of PetroChina and the Independent Shareholders (or the Shareholders for CRMSC Transactions) as a whole. Accordingly, we advise the Independent Board Committee to recommend the Independent Shareholders (or the Shareholders for CRMSC Transactions) to vote in favor of the relevant ordinary resolutions in the EGM. ---------------------------------------- Yours faithfully, For and on behalf of ICEA Capital Limited Fabian Shin Executive Director -29- APPENDIX GENERAL INFORMATION 1.
