REASONS FOR THE ACQUISITION AND BENEFIT TO THE COMPANY

The Company is principally engaged in the exploitation of oil and gas resources
in the PRC. The Board considers that the acquisition of the assets of the
Northeast China Inspection and Maintenance Operations is in line with the
development strategies of the Group as a whole.

Following the Company's expansion in the production scale of its refining and
chemical businesses and increase in equipment used, the installation, design,
supervision, inspection and maintenance works will be remained at a high growth
rate. At present, inspection and maintenance services of the refining and
chemical businesses are undertaken by various local branch companies. The
resources allocation for inspection and maintenance services in the Northeast
China are not concentrated and business developments was imbalanced resulting
from factors like the operations run by the holding entity and local
environments. These have impaired the development of the inspection and
maintenance business.

The Acquisition is intended to enhance the ability to safely and smoothly
operate the inspection and maintenance services, and to consolidate the
inspection and maintenance resources of the target entities, with a view to form
a comprehensive production chain for the technological servicing of refining and
chemical works. This would enable the unification of design, purchasing and
construction, and subsequent operations and maintenance services, thereby
strengthening and ensuring the inspection and maintenance services in a steady
manner. This will also secure the implementation of new mechanisms of the
refining and chemical business. The Acquisition will also reduce connected
transactions between CNPC and the Group to a certain extent, improve enforcement
of projects, and lead to improvements on the production chain of the refining
and chemical businesses, with a view to uplift servicing capacity
comprehensively and create synergy, and hence improving the technology level and
competitiveness of the inspection and maintenance services of the refining and
chemical business. The Acquisition will play an important role to the Company's
adopting centralized resource allocation and human resources management, to
maximize the Company's edge on resources in human resources, materials and
technologies, to formulate inspection and maintenance quotas scientifically, to
coordinate plans on inspection and maintenance services, balancing workload in
providing services, to improve quality of the services provided, and to
effectively increase the profitability of the inspection and maintenance
business, hence maximizing value to the shareholders of the Company in the long
run.

RELATIONSHIP BETWEEN THE PARTIES AND CONNECTED TRANSACTION

CNPC is the controlling shareholder (as defined in the Listing Rules) of the
Company holding 86.29% of the issued share capital of the Company. Pursuant to
the Listing Rules, CNPC is a connected person of the Company and the Acquisition
constitutes a connected transaction of the Company. Since the applicable
percentage ratio for the Acquisition is more than 0.1% but less than 2.5% for
the Group, the Company is only subject to the reporting and announcement
requirement and is exempt from the independent shareholders' approval
requirement under the Listing Rules.

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