developing our offshore resources and expanding our natural gas platform. The

funding to support our growth strategy."

Dr. Mark Qiu, Chief Financial Officer and Senior Vice President, added, "We

arrangement whereby any such securities or interests may be issued during the
said period or enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of

Conditions Precedent of the Subscription Agreement

Completion of the Subscription Agreement is conditional upon, among other
things:



                                      4


(i)    the execution of a trust deed constituting the Bonds and a paying and
       conversion agency agreement by all respective parties each in a form
       satisfactory to the Lead Managers;

(ii)   the Stock Exchange shall have agreed, subject to any conditions
       reasonably satisfactory to the Lead Managers, to list the Bonds and the
       Stock Exchange shall have agreed to list the Shares to be issued upon
       conversion of the Bonds (or, in each case, the Lead Managers being
       reasonably satisfied that such listing will be granted);

(iii)  the delivery to the Managers by the Company of legal opinions in
       relation to, amongst other things, enforceability of the Subscription
       Agreement, from English counsels in the form reasonably satisfactory to
       the Lead Managers; and

(iv)   the delivery to the Managers of auditors' comfort letters in relation
       to the Group's certain financial information in the form reasonably
       satisfactory to the Lead Managers.

In the event that the conditions are not fulfilled or waived in whole or in
part by the Closing Date in accordance with the terms of the Subscription
Agreement, the parties to the Subscription Agreement shall be released and
discharged from their respective obligations under the Subscription Agreement.
The Lead Managers, not the Company, may (on behalf of the Managers) waive
compliance with all or any of the conditions above. The Lead Managers have not
indicated that they will waive any of the conditions as at the date of this
announcement. None of the above conditions has been fulfilled as at the date
of this announcement. If listing approval for the Conversion Shares is not
granted, the Company expects the Lead Managers will not waive this condition.

Termination

The Lead Managers may also by notice in writing to the Company given any time
prior to the payment of net subscription monies to the Company for the Bonds
terminate the Subscription Agreement in any of the following circumstances:

(i)    if there shall have come to the notice of the Lead Managers any breach
       of, or any event rendering untrue or incorrect in any respect, any of
       the warranties and representations contained in the Subscription
       Agreement or any failure to perform any of the Company's undertakings
       or agreements in the Subscription Agreement; or

(ii)   if there shall have occurred any change, or any development involving a
       prospective change, in national or international monetary, financial,
       political or economic conditions or currency exchange rates or foreign
       exchange controls which would in the Lead Managers' view be likely to
       prejudice materially the success of the offering and distribution of
       the Bonds or dealings in the Bonds in the secondary market; or

(iii)  if there shall have occurred a general moratorium on commercial banking
       activities in the United Kingdom or United States or Hong Kong or
       Singapore by any United Kingdom, New York State, United States Federal
       or Hong Kong or Singapore authorities which would in the Lead Managers'
       view be likely to prejudice materially the success of the offering and
       distribution of the Bonds or dealings in the Bonds in the secondary
       market; or

(iv)   if on or after the date of the Subscription Agreement there shall have
       occurred either of the following: (i) a suspension or material
       limitation of trading in securities generally on the New York Stock
       Exchange, the London Stock Exchange plc, or the Hong Kong Stock
       Exchange; or (ii) a suspension in trading in the Company's securities
       on the Hong Kong Stock Exchange (save in circumstances in which such
       suspension is routine in nature), which in either case would in the
       Lead Managers' view be likely to prejudice materially the success of
       the offering and distribution of the Bonds or dealings in the Bonds in
       the secondary market; or

(v)    if there shall have occurred an outbreak or escalation of hostilities
       or act of terrorism which would in the Lead Managers' view be likely to
       prejudice materially the success of the Offering and distribution of
       the Bonds or dealings in the Bonds in the secondary market.

Upon such termination, the Subscription Agreement shall be of no further
effect save for accrued liability as provided in the Subscription Agreement.
Subject to the foregoing, the Subscription Agreement is expected to be
completed on the Closing Date and the Bonds are expected to be issued on the
Closing Date.

Conversion



                                      5


The initial Conversion Price at HK$6.075 per Share represents a premium of
35.75% to the closing price of the Shares quoted on the Stock Exchange on 25th
November, 2004 of HK$4.475; (ii) a premium of 36.36% to the 5-day average
closing price of the Shares over the 5 Trading Days up to and including 25th
November, 2004 of HK$4.455; and (iii) a premium of 40.54% to the 10-day
average closing price of the Shares over the 10 Trading Days up to and
including 25th November, 2004 of HK$4.323. The premium reflects the confidence
which the Company places on its share price.

The initial Conversion Price of HK$6.075 per Share is negotiated between the
Company and the Lead Managers (on behalf of the Managers) on an arm's length
basis and by reference to the closing price of the Shares on the Stock
Exchange on 25th November, 2004.

amount or integral multiples thereof) of the Bonds at the Early Redemption
Amount.

Redemption for Taxation Reasons

The Company may redeem all, but not some only, of the Bonds at the Early
Redemption Amount together with accrued interest in the event of changes in,
or amendment to, the laws and regulations regarding taxation in Hong Kong or
such other relevant jurisdictions.

Redemption for Delisting or Change of Control

Exchange; or (ii) the occurrence of a Change of Control with respect to the
Company.

Form of the Bonds and Denomination

The Bonds will constitute direct, senior, unsubordinated, unconditional and
(subject to the terms and conditions of the Bonds) unsecured obligations of
the Company and shall at all times rank pari passu and without any preference
or priority among themselves.

Bondholders will not have any voting rights until and unless they have
converted their Bonds into Conversion Shares.

selectively marketed securities. The Company will apply to the Stock Exchange
for the listing of, and permission to deal in, the Conversion Shares.

The Company has not raised any funds by means of equity in the past twelve
months other than the Shares issued pursuant to the exercise of the options
granted under the Company's share option schemes.

Fees

A combined management and underwriting commission and selling concession will
be charged by the Managers and paid by the Company.

Effect On The Share Capital Of The Company As A Result Of Conversion



                                      7

Reasons For And Benefits Of The Bonds Issue

The Bonds Issue will raise immediate funds for the Company which can be used
for general corporate and working capital purposes. No particular acquisition,
projects or plans which will be funded by the Bonds Issue has been identified

The conversion of the Bonds into the Conversion Shares will enlarge the
shareholder capital base of the Company and the Directors consider that this
will facilitate the development and expansion of the Company. Taking into
account that the Conversion Price represents a premium to the closing price of
the Shares as quoted on the Stock Exchange on 25th November, 2004, the
Directors are of the view that the terms and conditions of the Bonds and the
Subscription Agreement are fair and reasonable and are in the interest of the
Group as a whole.

General

The principal activities of the Group are the exploration, development,
production and sale of crude oil, natural gas and other petroleum products.

The Company will notify the Stock Exchange if it becomes aware of any dealings
in the Bonds by any directors, chief executive and substantial shareholders of
the Company or its subsidiaries or any of their respective associates or any
connected persons (as defined in the Listing Rules) of the Company and will
comply with the Listing Rules.

Completion of the Subscription Agreement is subject to the satisfaction and/or
waiver of the conditions precedent therein. In addition, the Subscription
Agreement may be terminated under certain circumstances. Please refer to the
paragraph headed "THE SUBSCRIPTION AGREEMENT" above for further information.

As the Subscription Agreement may or may not complete, Shareholders and
potential investors are



                                      8
