BHP BILLITON AND PETROHAWK ENERGY CORPORATION ANNOUNCE MERGER AGREEMENT         
BHP Billiton (ASX: BHP, NYSE: BHP, LSE: BLT, JSE: BIL) and Petrohawk Energy     
Corporation ("Petrohawk") (NYSE: HK) announced today that the companies have    
entered into a definitive agreement for BHP Billiton to acquire Petrohawk       
for US$38.75 per share by means of an all-cash tender offer for all of the      
issued and outstanding shares of Petrohawk, representing a total equity         
value of approximately US$12.1 billion and a total enterprise value of          
approximately US$15.1 billion, including the assumption of net debt. The        
Petrohawk board of directors has unanimously recommended to Petrohawk           
shareholders that they accept the offer.                                        
The transaction would provide BHP Billiton with operated positions in the       
three world class resource plays of the Eagle Ford and Haynesville shales,      
and the Permian Basin. Petrohawk`s assets cover approximately 1,000,000 net     
acres in Texas and Louisiana, with estimated 2011 net production of             
approximately 950 million cubic feet equivalent per day (MMcfe/d), or 158       
thousand barrels of oil equivalent per day (Mboe/d).  At year-end 2010,         
Petrohawk reported proved reserves of 3.4 trillion cubic feet of natural gas    
equivalent (Tcfe).  The company has a current non-proved resources base of      
32 Tcfe for a total risked resource base of 35 Tcfe. Petrohawk reported         
gross assets of US$8.2 billion as at 31 March 2011 and US$390 million of        
profit before tax for the year ended 31 December 2010.                          
BHP Billiton CEO, Marius Kloppers, said the acquisition was a natural fit       
with BHP Billiton`s strategy.                                                   
"The proposed acquisition of Petrohawk is consistent with our well defined,     
upstream, Tier 1 strategy and provides us with even greater exposure to the     
world`s largest energy market, while also broadening our geographic and         
customer spread. Importantly, our offer and the associated substantial          
premium represent a unique opportunity for Petrohawk shareholders and           
recognise the growth opportunities embedded in its portfolio immediately."      
BHP Billiton Petroleum Chief Executive, J. Michael Yeager, said the             
Petrohawk acquisition would add high quality growth to the company.             
"Petrohawk has a focused portfolio of three world class onshore natural gas     
and liquids rich shale assets. With over a decade of significant investment     
and volume growth ahead, this transaction would build on our recent             
acquisition of the Fayetteville shale in Arkansas and provides the potential    
to more than double our existing resource base.  Following completion of the    
Petrohawk transaction, BHP Billiton Petroleum will be on track to deliver a     
compound annual production growth rate of more than 10 per cent for the         
remainder of the decade as we accelerate our shale development program and      
leverage our strategic capability in the deep water.                            
"Importantly, BHP Billiton would retain Petrohawk`s sizeable U.S. based         
workforce, which has been at the forefront of the technological innovation      
that brought about the economic viability of U.S. shales. We look forward to    
extending our dedication to safeguarding the environment and the communities    
where we operate and continuing our commitment to safe and responsible          
operating practices across all of our shale gas plays, including the world-     
class assets that Petrohawk would bring to our portfolio."                      
Petrohawk CEO, Floyd Wilson, stated: "We believe these premium oil and          
natural gas assets would benefit significantly by residing within a larger      
entity that can employ more capital intensity to accelerate their realised      
value. We are excited to see this transaction completed and to be part of       
the BHP Billiton organisation."                                                 
The tender offer is expected to commence by 25 July 2011.  The acquisition      
is subject to the terms and conditions set forth in the merger agreement,       
including a condition that at least a majority of the outstanding Petrohawk     
shares are tendered, that the waiting period under the U.S. Hart-Scott-         
Rodino Antitrust Improvements Act of 1976, as amended, has expired or been      
terminated and that clearance is obtained from the Committee on Foreign         
Investment in the United States, and other customary conditions. If the         
tender offer is completed, un-tendered shares of Petrohawk will be converted    
into the right to receive the same US$38.75 per share price paid in the         
tender offer.  The transaction is to be financed from existing cash             
resources and a new credit facility and is not subject to any financing         
contingency. The transaction is expected to close in the third quarter of       
2011.                                                                           
BHP Billiton has engaged Barclays Capital and Scotia Waterous as financial      
advisors in connection with this Offer. Its legal advisors are Sullivan &       
Cromwell LLP and Morgan, Lewis & Bockius LLP in the United States.  Barclays

risks and uncertainties relate to factors that are beyond the BHP Billiton      
Group`s ability to control or estimate precisely, and any or all of the BHP     
Billiton Group`s forward-looking statements may turn out to be wrong. The       
BHP Billiton Group cannot give any assurance that such forward-looking          
statements will prove to have been correct. The reader is cautioned not to      
place undue reliance on these forward-looking statements, which speak only      
as of the date of this communication. The BHP Billiton Group disclaims any      
intention or obligation to update or revise any forward-looking statements,     
whether as a result of new information, future events, conditions,              
circumstances or otherwise, except as required by applicable law.               
Nothing contained herein shall be deemed to be a forecast, projection or        
estimate of the future financial performance of any member of the BHP           
Billiton Group, Petrohawk or the enlarged BHP Billiton Group following          
completion of the Offer, the merger and other related transactions unless       
otherwise stated.                                                               
The SEC permits oil and gas companies to disclose only proved, probable or      
possible reserves that a company has demonstrated by actual production or       
conclusive formation tests to be economically and legally producible under      
existing economic and operating conditions. BHP Billiton uses the term "non-    
proved resources base" in this release to refer to reserves other than          
proved, probable or possible reserves, which the SEC`s guidelines strictly      
prohibit us from including in filings with the SEC, except in connection        
with an acquisition.  This term includes estimates which are not yet            
classified as proved, probable or possible reserves.    These estimates are     
by their nature more speculative than estimates of proved, probable and         
possible reserves and accordingly are subject to substantially greater risk     
of being actually realized. Non-proved resources base refers to internal        
estimates of hydrocarbon quantities that may be potentially discovered          
through exploratory drilling or recovered with additional drilling or           
recovery techniques and have not been reviewed by independent engineers and     
do not constitute reserves within the meaning of the Society of Petroleum       
Engineer`s Petroleum Resource Management System and does not include proved     
reserves.  Actual quantities that may be ultimately recovered from these        
properties will differ substantially.  Factors affecting ultimate recovery      
include the scope of the ongoing drilling program, which will be directly       
affected by the availability of capital, drilling and production costs,         
availability of drilling services and equipment, drilling results, lease        
expirations, transportation constraints, regulatory approvals and other         
factors; and actual drilling results, including geological and mechanical       
factors affecting recovery rates.  Estimates of the non-proved resources        
base may change significantly as development provides additional data.          
Investors are urged to consider the disclosures in BHP Billiton`s periodic      
filings with the SEC, available from us at Neathouse Place, London, SW1V        
1BH, United Kingdom and the Company`s website at www.bhpbilliton.com. You
