INTRODUCTION

Pursuant to the Merger Agreement entered into between Beijing Feitian and
Beijing Yanhua on 29th December 2004, Beijing Yanhua Directors agreed to put
forward the Proposal to the Beijing Yanhua Shareholders.

Beijing Feitian was incorporated in the PRC for the purposes of the Merger and
is wholly owned by Sinopec Corp. Sinopec Corp. is a joint stock company
incorporated in the PRC with limited liability, and is owned as to
approximately 67.917% by China Petrochemical Corporation, which is a PRC
state-owned enterprise. Sinopec Corp. is the controlling shareholder of
Beijing Yanhua, being interested in approximately 70% of the issued share
capital of Beijing Yanhua (representing 100% of the Beijing Yanhua Domestic
Shares).

TERMS OF THE PROPOSAL

The Proposal is made pursuant to and in accordance with Article 184 of the PRC
Company Law.

Under the Merger Agreement, on the date of de-registration of Beijing Yanhua,
(i) Beijing Yanhua will be merged into Beijing Feitian, with Beijing Feitian
as the surviving corporation and will cease to exist as a separate legal
entity; and (ii) the assets and liabilities (together with the rights and
obligations attached to such assets) and the employees of Beijing Yanhua will
be assumed by Beijing Feitian. This "merger by absorption" is provided for
under the PRC Company Law and the Beijing Yanhua Articles.

Pursuant to the Proposal, Beijing Feitian will (i) pay the Cancellation Price
per Beijing Yanhua H Share in cash to the Beijing Yanhua H Shareholders for
the cancellation of all Beijing Yanhua H Shares and (ii) issue
RMB4,163,335,400 of new registered capital of Beijing Feitian to Sinopec
Corp., being the sole holder of all the Beijing Yanhua Domestic Shares. The
Cancellation Price represents a premium of approximately 10.9% over the
closing price of HK$3.425 per Beijing Yanhua H Share as quoted on the Hong
Kong Stock Exchange on 21st December 2004 (being the last date of trading
prior to the suspension of trading in the Beijing Yanhua H Shares pending the
issue of this announcement).

The Proposal requires approvals from the relevant PRC governmental and
regulatory bodies (including approvals of, inter alia, the CSRC (if
applicable), SASAC and SAFE).

According to the Beijing Yanhua Articles, any Beijing Yanhua Shareholder who
has opposed the Proposal may request Beijing Yanhua or other Beijing Yanhua
Shareholders who have approved the Proposal to acquire its Beijing Yanhua
Shares at a "fair price". The Merger Agreement provides that if any Beijing
Yanhua Shareholder elects to request Beijing Yanhua or other Beijing Yanhua
Shareholders who have voted for the Proposal to purchase its Beijing Yanhua
Shares at a "fair price", Beijing Feitian shall, at the request of Beijing
Yanhua or such Beijing Yanhua Shareholder, assume any liability which Beijing
Yanhua or such Beijing Yanhua Shareholder who has received such a request may
have towards the dissenting Beijing Yanhua Shareholder. The Merger Agreement
further provides that if more than 5% of the Beijing Yanhua H Shareholders
make such request, the Merger will lapse, unless Beijing Feitian decides to
waive this condition.

Beijing Yanhua is also required by the PRC Company Law and the Beijing Yanhua
Articles to notify its creditors of the Proposal. Beijing Yanhua's creditors
may require Beijing Yanhua to pay off its indebtedness or provide a
satisfactory guarantee for such indebtedness, failing which, according to the
PRC Company Law, the Proposal may not proceed. If the Independent Beijing
Yanhua Shareholders approve the Merger during the Special General Meeting of
the Independent Beijing Yanhua Shareholders, Beijing Yanhua and Beijing
Feitian will each publish an announcement on the day immediately after the
Special General Meeting of the Independent Beijing Yanhua Shareholders was
convened giving notice to their respective creditors of the Proposal. If any
creditor requests repayment of the indebtedness owed by Beijing Yanhua or
Beijing Feitian (as appropriate) or requests for any guarantee in relation to
such indebtedness, such request will have to be made within a 90-day period
from the date of such announcement. Upon the expiry of the relevant period
specified in the above announcement, such creditor's right to claim against
Beijing Yanhua or Beijing Feitian (as appropriate) shall lapse under PRC law.

INFORMATION ON BEIJING FEITIAN

Beijing Feitian is a wholly owned subsidiary of Sinopec Corp. established in
the PRC. It is 95% owned by Sinopec Corp. and 5% owned by Sinopec
International. Sinopec International is a wholly owned subsidiary of Sinopec
Corp. Beijing Feitian has been established for the purpose of the Merger and
has no substantive business.

REASONS FOR AND BENEFITS OF THE MERGER

Sinopec Corp. and Beijing Yanhua have identified a number of reasons for and
benefits of the Merger. These include:

1.    The Merger can consolidate and strengthen the management of Sinopec
      Corp. and Beijing Yanhua. Beijing Yanhua's petrochemical business will
      be consolidated into Sinopec Corp.'s integrated oil and petrochemical
      operation under a leaner and more efficient group structure, which will
      be beneficial to Sinopec Corp. for achieving business strategies and
      objectives for the group as a whole.

2.    The Merger can reinforce the business value chain of Beijing Yanhua
      through the vertical integration of Beijing Yanhua's petrochemical
      assets with the upstream refining operation of Sinopec Corp.

3.    The Merger can consolidate Sinopec Corp.'s resources and realize
      potential synergies. The Merger will enable Sinopec Corp. to improve the
      utilization of capital resources by centralising capital allocation and
      enhancing capital expenditure management. After the Merger, Sinopec
      Corp. can leverage its brand name, marketing capabilities and
      distribution network to achieve economies of scale and reduce operations
      costs.

4.    The Merger can effectively eliminate intra-group competition. At
      present, both Sinopec Corp. and Beijing Yanhua are engaged in the
      petrochemical business with similar products and competing sales
      channels. After the Merger, combined production and sales will
      effectively eliminate this intra-group competition.

5.    The Proposal offers all Beijing Yanhua H Shareholders a unique
      opportunity to realise their investments in Beijing Yanhua at a cash
      consideration which represents a premium over the market price of
      Beijing Yanhua H Shares.

-------------------------------------------------------------------------------

-------------------------------------------------------------------------------

WITHDRAWAL OF LISTING OF BEIJING YANHUA H SHARES AND BEIJING YANHUA ADSs

Upon fulfilment (or waiver, if applicable) of other Conditions, Beijing Yanhua
will apply for its de-registration and the Beijing Yanhua Listing will be
withdrawn. After the de-registration process of Beijing Yanhua is completed,
all Beijing Yanhua H Shares will no longer exist. Share certificates for the
Beijing Yanhua H Shares will thereafter cease to have effect as documents or
evidence of title and Beijing Yanhua will cease to exist as a legal entity.
The Beijing Yanhua ADSs will then be delisted on the New York Stock Exchange.
The Beijing Yanhua Shareholders will be notified by way of an announcement of
the exact date on which the relevant Conditions have been fulfilled (unless
waived, as applicable) and the date on which the Beijing Yanhua Listing is
withdrawn. The Merger will lapse if the Conditions are not fulfilled (unless
waived, as applicable) on or before 31st December 2005 (or such other date as
Beijing Yanhua and Beijing Feitian may agree) and the Beijing Yanhua
Shareholders will be notified by way of an announcement accordingly. A
detailed timetable for the Proposal will be included in the Composite Document
to be despatched to Beijing Yanhua Shareholders, which will also contain,
inter alia, further details of the Proposal and the Merger.

Any Beijing Yanhua Shareholder who has opposed the Proposal and has requested
Beijing Yanhua or other Beijing Yanhua Shareholders who have approved the
Proposal to acquire its Beijing Yanhua Shares at a "fair price" will, after
the de-registration of Beijing Yanhua, continue to have a right against
Beijing Yanhua and/or such Beijing Yanhua Shareholder, or Beijing Feitian (if
requested by Beijing Yanhua and/or such Beijing Yanhua Shareholder to assume
their respective liabilities after receiving the request from the dissenting
Beijing Yanhua Shareholder).

The Beijing Yanhua Listing will not be withdrawn and an application to delist
the Beijing Yanhua ADSs on the New York Stock Exchange will not be made if the
Merger is not approved or if the Proposal lapses or if any Condition is not
fulfilled (unless waived, as applicable).

laws of the relevant jurisdiction in connection therewith, including the
obtaining of any governmental, exchange control or other consents which may be

of any issue, transfer or other taxes due in such jurisdiction. Beijing Yanhua
will be making necessary enquiries to determine whether or not it would be
unduly burdensome to send the Composite Document to any of the Overseas
Beijing Yanhua Shareholders. If appropriate, Sinopec Corp. or Beijing Feitian
will apply for a waiver from the Executive pursuant to Note 3 to Rule 8 of the
Takeovers Code, from the requirement to send the Composite Document to such
Overseas Beijing Yanhua Shareholders. The Executive may or may not grant such
a waiver.
