                          POSSIBLE MAJOR TRANSACTION

------------------------------------------------------------------------------
On 28 April 2006,  AsiaSat, a wholly owned subsidiary of the Company,  entered
into a Construction Agreement with the Construction Contractor, an independent
third party not associated  with the Directors,  chief  executive  officer and
substantial  shareholder of the Company and any of its  subsidiaries or any of
their  associates as defined in the Listing  Rules,  for the  construction  of
AsiaSat  5, a Space  Systems/Loral  1300  satellite  bus with 26 C-band and 14
Ku-band transponders.

The  signing  of  the  Construction   Agreement  is  a  step  forward  in  the
implementation  of the  Company's  plan for the  commissioning  of  AsiaSat 5.
Subsequent to the signing of this Construction Agreement, AsiaSat will proceed
with the  launching  arrangement  in which  AsiaSat  will  enter into a launch
contract ("Launch Contract") with an independent third party launching service
provider  for the  launching  of  AsiaSat  5. The  consideration  of the above
contracts  together with the insurance cost for the commissioning of AsiaSat 5
is estimated at approximately  US$180.00  million  (approximately  HK$1,404.00
million*)  in total.  The  transaction  contemplated  under  the  Construction
Agreement  constitutes  a  discloseable  transaction  of the Company under the
Listing Rules. If the relevant Launch Contract is committed  within a 12 month
period, the launching of AsiaSat 5, taking into consideration the Construction
Agreement,  the Launch Contract and the related  insurance,  will constitute a
major transaction of the Company under the Listing Rules.

The transaction  contemplated under the Construction  Agreement  constitutes a
discloseable  transaction  of the Company  under the Listing Rules whereas the
commissioning of AsiaSat 5, when taking the Construction  Agreement and, inter
alia,  the cost of launching and the cost of launch  insurance,  together will
constitute a major  transaction  of the Company under the Listing  Rules.  The
Company  considers that it would be more  advantageous to its shareholders and
has applied to the Stock  Exchange for an extension of time in relation to the
despatch  of the  Circular,  and  issue  a  combined  circular  on the  entire
commissioning  arrangement  for  AsiaSat  5  covering  both  the  Construction
Agreement and the subsequent Launch Contract.  Accordingly, the Stock Exchange
has granted a waiver in  relation to the delay in despatch of the  circular on
the Construction Agreement until 26 June 2006.

The  Company  has also  applied to the Stock  Exchange  for a waiver from full
compliance  with rules  14.58(4) and 14.66(1) of the Listing Rules in relation
to the disclosure of the aggregate value
------------------------------------------------------------------------------



------------------------------------------------------------------------------
of consideration under the Construction Agreement.

Upon the signing of the Launch Contract,  a further  announcement will be made
and a  circular  giving  details  of the  Construction  Agreement,  the Launch
Contract and the  commissioning  of AsiaSat 5 will be sent to the shareholders
accordingly.  Where permissible under the Listing Rules, the Company will seek
to obtain the  requisite  shareholders'  approval  by  obtaining  the  written
approval from the Company's controlling shareholder,  Bowenvale Limited, which
owns approximately 69 percent of the issued share capital of the Company.

AsiaSat has initiated the process of  negotiation in relation to the launching
arrangement.  Whilst AsiaSat intends to launch AsiaSat 5 in the second quarter
of 2008, the terms of the Launch Contract has not yet finalised.  Shareholders
and  investors  are advised to exercise  extreme  caution  when dealing in the
securities in the Company.
------------------------------------------------------------------------------


INTRODUCTION

To ensure  the  sustaining  of  AsiaSat's  market  competitiveness,  strategic
positioning  of our  satellites  and the offering of the very best services in
the years ahead, we have procured the new satellite, AsiaSat 5, to replace the
retiring  AsiaSat 2 at the  orbital  location  of 100.5  degrees  East.  Since
AsiaSat 2 is tentatively scheduled to be retired in 2010, we have planned this
replacement  satellite to be launched in 2008 so as to allow  sufficient  time
for the constructing and launching of a replacement  satellite in the event of
an unsuccessful launch of the AsiaSat 5.

On 28 April 2006,  AsiaSat, a wholly owned subsidiary of the Company,  entered
into a Construction Agreement with the Construction Contractor, an independent
third party not associated  with the Directors,  chief  executive  officer and
substantial  shareholder of the Company and any of its  subsidiaries or any of
their  associates  as defined in the  Listing  Rules for the  construction  of
AsiaSat 5 as a step forward to implement  Company's plan for the commissioning
of AsiaSat 5. In the  meantime,  AsiaSat  will  proceed  with the  sourcing of
launching  service and the  procurement of other  relevant  facilities for the
commissioning of AsiaSat 5.

CONSTRUCTION AGREEMENT

DATE

28 April 2006

PARTIES

1.     The  Construction  Contractor,  a party  independent  of the Directors,
       chief executive officer and substantial  shareholder of the Company and
       its  subsidiaries  and their  respective  associates  as defined in the
       Listing Rules




2.     AsiaSat, a wholly owned subsidiary of the Company

SUBJECT MATTER

The Construction Contractor will provide for AsiaSat the design, construction,
assembly,   testing,   production   and  delivery  of  AsiaSat  5,  and  other
professional  services and labour for the construction of AsiaSat 5, including
studies,  development,   research,  design,  analysis,  manufacture,   product
assurance,  product integration,  transportation and testing. In addition, the
Construction  Contractor will provide all necessary  technical  support to the
prospective launch services provider to permit testing integration and launch.

The Construction  Contractor will also provide the  royalty-free,  world-wide,
non-exclusive,  non-transferable,  paid-up license for AsiaSat to use the data
and  information,   including,  without  limitation  to,  technical  data  and
information  contained in reports,  documents,  computer  programs,  diagrams,
drawings and graphs that AsiaSat  requires for the purpose of the construction
and the operation of AsiaSat 5.

The Construction  Contractor will further  indemnify AsiaSat and defend on its
own expenses on third party  requests,  claims,  actions and  proceedings  for
royalty  payments,  equitable  relief or  damages  against  AsiaSat  based any
infringement  of patent,  trade mark,  or copy right or trade  secret from the
manufacturing  of the items;  and to pay any  royalties and other costs in the
settlement  of such request and the costs and damages  finally  awarded to the
third party on the claim.

TITLE

The title to the  AsiaSat 5 shall pass to AsiaSat at the moment of launch.  In
the event  AsiaSat 5 is not  launched  within 3 years after it is completed by
the  Construction  Contractor,  AsiaSat shall pay all monies payable under the
Construction  Agreement  and  have the  title  to  AsiaSat  5  subject  to the
obtaining of requisite US Government approvals.

COMPLETION

Under the terms of the Construction  Agreement , the  Construction  Contractor
shall complete the  construction  of AsiaSat 5 to be available for shipment to
the launch site within 25 months after 28 April 2006.



Subject to the entering  into the  necessary  Launch  Contract  and  launching
arrangements,  AsiaSat  intends to launch  AsiaSat 5 in the second  quarter of
2008.

LAUNCHING OF ASIASAT 5

Subsequent to the signing of this Construction Agreement, AsiaSat will proceed
with the  launching  arrangement  in which  AsiaSat  will  enter into a Launch
Contract  with  a  prospective   independent  third  party  launching  service
provider.

AsiaSat has initiated the process of  negotiation in relation to the launching
arrangement.  Whilst AsiaSat intends to launch AsiaSat 5 in the second quarter
of 2008, the terms of the Launch Contract has not yet finalised.  Shareholders
and  investors  are advised to exercise  extreme  caution  when dealing in the
securities in the Company.

TOTAL COST FOR THE COMMISSIONING OF ASIASAT 5

The Directors  estimated that the total cost for the  commissioning of AsiaSat
5, including not only the contract price under the Construction  Agreement and
the cost of  launching,  but also the costs of the  launch  insurance,  ground
facilities  for  telemetry,   tracking  and  control,   related  expenses  and
capitalised   interest,   will   be   at   approximately   US$180.00   million
(approximately  HK$1,404.00 million*).  This estimation is subject to a number
of factors  including the timely  completion  of AsiaSat 5, certain  delays or
postponements  in  launching,  the  in-orbit  performance  of  AsiaSat 5 after
launching. The estimated cost for commissioning AsiaSat 5 will be fully funded
by internal resources of AsiaSat.

The contract price and the terms of the Construction Agreement were negotiated
on an arm's  length  basis  having  regard to the value of  similar  assets as
quoted by the other  constructors and based on a previous similar  acquisition
of a satellite by AsiaSat in 2000**.  Such contract price will be paid in cash
in stages and the final  instalment  shall be paid upon completion of in-orbit
testing,  scheduled to take place after 27 months of the effective date of the
Construction  Agreement,  or in the  event  AsiaSat  5 is  completed  but  not
launched,  3 years after it is  completed.  The price  under the  Construction
Agreement  will be fully  funded  by  internal  resources  of  AsiaSat.  It is
expected that AsiaSat 5 will be launched in the second quarter of 2008.

OPTION

AsiaSat has an option to order an additional satellite  substantially  similar
to AsiaSat 5 subject to price  adjustment  based on an indexation  computed by
the aircraft  manufacturing price and



employment cost indexes  published by the U.S.  Department of Labour.  AsiaSat
intends to  exercise  this  option in the event of an  unsuccessful  launch of
AsiaSat 5. The Company will comply with the requisite  requirements  under the
Listing Rules as and when the option is exercised,  and a further announcement
will be made if and when required.

REASONS AND BENEFITS OF THE COMMISSIONING OF ASIASAT 5

The new  AsiaSat 5 will  replace  AsiaSat 2 at the  orbital  location of 100.5
degrees  East and allow our  market  competitiveness,  strategic  position  of
satellites  and the offering of the very best services to be sustained for the
years  ahead.  It will  replace all current  functions  of AsiaSat 2 in C band
coverage, and in Ku band, provide additional dedicated coverage for South Asia
plus a steerable beam.

The C band  payload of AsiaSat 5 will be similar to that of AsiaSat 2 save for
some performance upgrades. As for the Ku band payload, its coverage over China
is  significantly  upgraded and  additional  coverage is also  provided for in
South Asia covering, inter alia, India, Pakistan and Bangladesh.  In addition,
the satellite  will carry a steerable  antenna that will allow  capacity of Ku
band to be deployed in a consistent  manner with the market demand anywhere in
Asia.

The Directors are of the view that the  transaction  has been conducted in the
ordinary  and usual course of business of the  Company,  on normal  commercial
terms  and the terms of the  transaction  are fair and  reasonable  and in the
interest of the shareholders of the Company as a whole.

INFORMATION TO SHAREHOLDERS

The transaction  contemplated under the Construction  Agreement  constitutes a
discloseable  transaction  of the Company  under the Listing Rules whereas the
commissioning of AsiaSat 5, when taking the Construction  Agreement and, inter
alia,  the cost of launching and the cost of launch  insurance,  together will
constitute a major  transaction  of the Company under the Listing  Rules.  The
Company  considers that it would be more  advantageous to its shareholders and
has applied to the Stock  Exchange for an extension of time in relation to the
despatch  of the  Circular,  and  issue  a  combined  circular  on the  entire
commissioning  arrangement  for  AsiaSat  5  covering  both  the  Construction
Agreement and the subsequent Launch Contract.  Accordingly, the Stock Exchange
has granted a waiver in  relation to the delay in despatch of the  circular on
the Construction Agreement until 26 June 2006.

The  Company  has also  applied to the Stock  Exchange  for a waiver from full
compliance  with rules  14.58(4) and 14.66(1) of the Listing Rules in relation
to  the  disclosure  of  the  aggregate  value  of  consideration   under  the
Construction Agreement.



Upon the signing of the Launch Contract,  a further announcement will be made,
and a  circular  giving  details  of the  Construction  Agreement,  the Launch
Contract and the  commissioning  of AsiaSat 5 will be sent to the shareholders
accordingly.  In the event  that the Launch  Contract  is not signed by 9 June
2006, a circular giving details of the Construction  Agreement will be sent to
the shareholders of the Company,  and upon signing of the Launch  Contract,  a
further  announcement  and circular  will be issued as required in  accordance
with the Listing Rules.

The Company envisages that any shareholders'  approval required in relation to
the  commissioning  of AsiaSat 5 under the Listing  Rules will,  to the extent
permissible  under the Listing Rules, be obtained by seeking written  approval
from the Company's  controlling  shareholder,  Bowenvale  Limited,  which owns
approximately 69 percent of the issued share capital of the Company.
