                             CONNECTED TRANSACTIONS

The Board wishes to announce that the Company has, on 28 March 2005, entered
into the Acquisition Agreement with CNPC. According to the Acquisition
Agreement, the Company has acquired the Refinery and Petrochemical Businesses
from CNPC for which the Company would pay a cash consideration of RMB9.14
million (approximately HK$8.54 million).

CNPC is the controlling shareholder of the Company holding 90% of the issued
share capital of the Company. As defined under the Listing Rules, CNPC is a
connected person of the Company and the Asset Acquisition (including the Land
Use Rights Leasing Arrangement) constitute connected transactions of the
Company.

Given that the percentage ratios involved in the Asset Acquisition (including
the Land Use Rights Leasing Arrangement) are more than 0.1% but less than 2.5%
for the Group, the Asset Acquisition (including the Land Use Rights Leasing
Arrangement) is only subject to reporting and announcement requirement and is
exempted from the independent shareholders' approval requirement under Rule
14A.32 of the Listing Rules.


ACQUISITION AGREEMENT DATED 28 MARCH 2005

PARTIES

Vendor:    CPNC
Purchaser: the Company

THE ASSET ACQUISITION



Subject to the satisfaction of certain conditions precedent under the
Acquisition Agreement, the Company will acquire the Refinery and Petrochemical
Businesses, which include both assets and liabilities. The major assets of the
Refinery and Petrochemical Businesses to be acquired by the Company principally
consist of refinery and petrochemical production facilities, 27 pieces of
granted land (occupying approximately 1.39 million square meters in total) and
buildings thereon, as well as certain ancillary assets (including 18 petrol
stations, two liquefied natural gas depots, movables, intangible assets,
long-term investments and deferred assets).

CONSIDERATION

The Asset Acquisition (including the Land Use Rights Leasing Arrangement) was
negotiated and entered into on an arm's length basis and on normal commercial
terms. A cash consideration of RMB9.14 million (approximately HK$8.54 million)
would be payable by the Company to CNPC at completion of the Asset Acquisition.

The above consideration was determined on the basis of the results of a
valuation report prepared by an independent valuer using the replacement cost
method, which was filed with and approved by the SASAC of the PRC and based on
the valuation reference date of 30 June 2004. According to the valuation report,
as at 30 June 2004 the aggregate value of the total assets to be acquired by the
Company pursuant to the Asset Acquisition was RMB1,891.59 million (approximately
HK$1,767.84 million) (out of which approximately RMB9.75 million (approximately
HK$9.11 million) assets of the primary and secondary school shall be transferred
to the local government as required under the applicable government policies at
the same time with the Asset Acquisition), the aggregate value of liabilities of
the Refinery and Petrochemical Businesses was RMB1,872.70 million (approximately
HK$1,750.18 million), and the aggregate net asset value was RMB9.14 million
(approximately HK$8.54 million).

After adjustments according to the IFRS, as at 30 June 2004 the aggregate value
of the total asset value of the Refinery and Petrochemical Businesses was
RMB1,777.62 million (approximately HK$1,661.33 million), the aggregate value of
the related liabilities was RMB1,872.74 million (approximately HK$1,750.22
million), and the aggregate value of net liabilities was RMB95.12 million
(approximately HK$88.90 million). Accordingly, after adjustments pursuant to the
IFRS, the consideration of the Asset Acquisition is that the Company would pay a
cash consideration of RMB9.14 million (approximately HK$8.54 million) and assume
liabilities in the aggregate amount of RMB95.12 million (approximately HK$88.90
million) in relation to the Refinery and Petrochemical Businesses. There is no
outstanding capital commitment remains to be fulfilled by CNPC in respect of the
Refinery and Petrochemical Businesses and the Company will not assume any such
commitments as a result of the Asset Acquisition.


For the purposes of the Listings Rules, the consideration for the Asset
Acquisition was based on the above net liabilities as adjusted according to
IFRS. The difference between the aggregate net asset value as valued by the
independent valuer and the aggregate value of the net liabilities as adjusted
according to the IFRS is due to the requirement under IFRS that transactions
between enterprises under common control 



shall be valued at their historical cost, which has resulted in the granted land
use rights to be acquired by the Company pursuant to the Asset Acquisition not
being able to be recognized at their appraised value under IFRS. The granted
land use rights held by Dayuan and Qingyang were previously booked at relatively
low historical costs of approximately RMB39 million (approximately HK$36.45
million) which do not reflect their current fair market value of approximately
RMB172.23 million (approximately HK$160.96 million). Accordingly, the current
valuation prepared by the independent valuer is a reflection of the current fair
market value of the Asset Acquisition.

China Enterprise Appraisal Company Limited, Beijing ([CHINESE CHARACTERS]) is
the independent valuer and Shenzhen Nanfang Minhe Certified Public Accountants
([CHINESE CHARACTERS]), a local accounting firm in Beijing is the auditors for
the Asset Acquisition.

CONDITIONS PRECEDENTS FOR THE COMPLETION OF THE ASSET ACQUISITION:

The completion of the Asset Acquisition is subject to the satisfaction of
certain conditions precedent, including:

(a)  the Company having completed due diligence review on the business
     conditions of the Refinery and Petrochemical Businesses;

(b)  the Company having completed the procedures and requirements in connection
     with the Asset Acquisition stipulated by the regulatory authorities of its
     place of listing;

(c)  CNPC having obtained the consents of the relevant creditors and other third
     parties in connection with the Asset Acquisition;

(d)  there having been no material adverse change to the business operations and
     technical performance of Dayuan and Qingyang; and

(e)  the representations, warranties and undertakings given by CNPC in relation
     to the Asset Acquisition being true, accurate, complete and valid as at the
     date of completion of the Asset Acquisition.

COMPLETION OF THE ASSET ACQUISITION

The Asset Acquisition shall be completed on the date of 1 April 2005 or the date
on which the above conditions precedents have been satisfied, whichever is the
later. As of the date of this announcement, all the above conditions have been
fulfilled and completion of the Asset Acquisition shall take place on 1 April
2005.

LAND USE RIGHTS LEASING ARRANGEMENT 
It is a term in the Acquisition Agreement that after completion of the Asset
Acquisition, CNPC will lease the 28 pieces of allocated land owned by CNPC with
a total gross floor area of 1,658,400 square meters, which was not included as
part of the Asset Acquisition, to the Company in connection with the operation
of the Refinery and Petrochemical Businesses for an initial period commencing
from the


completion of the Asset Acquisition and up to 31 December 2005 for a total
consideration of RMB 2.45 million, payable in cash by the Company to CNPC within
10 working days from the effective date of the Acquisition Agreement. CNPC shall
pay all taxes and other statutory expenses in connection with the lease of such
allocated land.

The percentage ratios calculated based on the annual consideration for the Land
Use Rights Leasing Arrangement would be less than 0.1% and thus the Land Use
Rights Leasing Arrangement by itself is exempted from the disclosure obligations
under the connected transaction requirements under Rule 14A.31(2) of the Listing
Rules. It is expected that after the initial period of up to 31 December 2005,
the Company will enter into a new leasing agreement with CNPC covering the
leases in relation to the Land Use Rights Leasing Contract together with the
leasing of the allocated land in connection with the Refinery and Petrochemical
Businesses. The Company will comply with the relevant requirements under the
Listing Rules in connection with such continuing leasing arrangements with CNPC.

REASONS FOR THE ASSET ACQUISITION

The market for refined petroleum and natural gas-related products is a
competitive and fairly active one in the PRC. As an integrated oil company with
a core focus on upstream businesses, one of the Company's established strategies
is to develop its refinery and petrochemical businesses.

The Board believes that despite the current difficult operating conditions faced
by Dayuan and Qingyang, for the two financial years ended 31 December 2003, the
aggregate losses both before and after taxation and extraordinary items
attributable to the Refinery and Petrochemical Businesses were RMB171.18 million
(approximately HK$159.98 million) and RMB407.75 million (approximately HK$381.07
million). For the financial year ended 31 December 2004, the aggregate losses
both before and after taxation and extraordinary items attributable to the
Refinery and Petrochemical Businesses were RMB148.86 million (approximately
HK$139.12 million). Dayuan and Qingyang respectively accounts for an average of
63.00% and 5.94% of the local provincial market for refined oil and
petrochemical products and an average of 75.00% and 8.50% of the local
provincial retail market. The Refinery and Petrochemical Businesses mainly
consist of refinery and petrochemical production facilities, petrol stations and
liquefied natural gas depots and a stable clientele.

The Board believes that the operating losses sustained by Dayuan and Qingyang in
the past two financial years were primarily due to a number of factors,
including: (i) relatively large provisions for impairment of assets; (ii)
relatively high operating costs which were attributable to a shortage of crude
oil supply, and therefore low utilization rates of the relevant refinery and
petrochemical production facilities; (iii) relatively high financing costs owing
to a shortage of funds and a relatively high level of debts; (iv) relatively
large number of labour involved resulting an increase in the cost of production;
and (v) technologies deployed in the production of refinery and petrochemical
products falling behind those currently deployed in the market, and hence
resulted in a low productivity in high value-added products and the losses.




The Board believes that the profitability of the Refinery and Petrochemical
Businesses can be significantly improved and better prospects for profits may be
created through the following measures: (i) strengthening the resources
allocation thereby ensuring a stable supply of crude oil; (ii) refinancing the
existing debts; (iii) reducing operating costs by reorganisation of the
management structure and reducing labour cost; (iv) continuing restructuring of
the operation; and (v) improving technology in the production of high value
added products. It is expected that the increase in the Group's proportion of
refinery and petrochemical businesses can provide room for an increase in gross
margin and lead to an increase in the Company's total sales income. The Asset
Acquisition will further improve the Company's refinery and petrochemical
businesses portfolio and increase its market share in the north-western region
of China and enhance its overall resistance to risks.


RELATIONSHIP BETWEEN THE PARTIES AND CONNECTED TRANSACTION

CNPC is the controlling shareholder of the Company holding 90% of the issued
share capital of the Company. CNPC is engaged in crude oil and natural gas
exploration and production business activities outside the PRC and limited
petrochemical production and retail of refined oil products. As defined under
the Listing Rules, CNPC is a connected person of the Company. Accordingly, the
Asset Acquisition (including the Land Use Rights Leasing Arrangement)
constitutes a connected transaction of the Company. Given the percentage ratios
involved in the Asset Acquisition (including the Land Use Rights Leasing
Arrangement) are more than 0.1% but less than 2.5% for the Group, the Company is
only subject to reporting and announcement requirement and is exempted from the
independent shareholders' approval requirement under Rule 14A.32 of the Listing
Rules.

The Board (including the independent non-executive directors) considers that the
terms and conditions of the Acquisition Agreement are on normal commercial terms
and are fair and reasonable and in the interests of the shareholders of Company
as a whole.
