ExxonMobil to Acquire InterOil in Transaction Worth More Than $2.5 Billion

• ExxonMobil to pay $45 per share plus additional cash payment based on Elk-Antelope resource size
• Boards of directors of both companies unanimously approve terms of agreement
• Acquisition adds to ExxonMobil resources in successful Papua New Guinea business
• Oil Search transaction terminated

“This agreement will enable ExxonMobil to create value for the shareholders of both companies and the people of Papua New Guinea,” said Rex W. Tillerson, chairman and chief executive officer of Exxon Mobil Corporation.

“InterOil’s resources will enhance ExxonMobil’s already successful business in Papua New Guinea and bolster the company’s strong position in liquefied natural gas.”

InterOil Chairman Chris Finlayson said, “Our board of directors thoroughly reviewed the ExxonMobil transaction and concluded that it delivers superior value to InterOil shareholders. They will also benefit from their interest in ExxonMobil’s diverse asset base and dividend stream.”

Under the terms of the agreement with ExxonMobil, InterOil shareholders will receive:

• A payment of $45.00 per share of InterOil, paid in ExxonMobil shares, at closing. The number of ExxonMobil shares paid per share of InterOil will be calculated based on the volume weighted average price (VWAP) of ExxonMobil shares over a measuring period of 10 days ending shortly before the closing date (Share Consideration).
• A Contingent Resource Payment (CRP), which will be an additional cash payment of $7.07 per share for each trillion cubic feet equivalent (tcfe) gross resource certification of the Elk-Antelope field above 6.2 tcfe, up to a maximum of 10 tcfe. The CRP will be paid on the completion of the interim certification process in accordance with the Share Purchase Agreement with Total SA, which will include the Antelope-7 appraisal well, scheduled to be drilled later in 2016. The CRP will not be transferrable and will not be listed on any exchange.

Together the Share Consideration and the CRP represent a material premium to the closing price of InterOil shares on May 19, 2016 -- the day prior to the announcement of the Oil Search transaction -- based on a range of Elk-Antelope resource estimates:

Compelling Benefits of the Transaction

When concluded, this transaction will give ExxonMobil access to InterOil’s resource base, which includes interests in six licenses in Papua New Guinea covering about four million acres, including PRL 15. The Elk-Antelope field in PRL 15 is the anchor field for the proposed Papua LNG project.

ExxonMobil’s more than 40 years of experience in the global LNG business enables it to efficiently link complex elements such as resource development, pipelines, liquefaction plants, shipping and regasification terminals, which it has demonstrated through the PNG LNG project, working closely with co-venturers, national, provincial and local governments, and local communities. ExxonMobil will bring to bear its industry-leading performance and strong commitment to excellence as it grows its business in Papua New Guinea.

The PNG LNG project, the first of its kind in the country, was developed by ExxonMobil in challenging conditions on budget and ahead of schedule and is now exceeding production design capacity, demonstrating the company’s leadership in project management and operations.

ExxonMobil will work with co-venturers and the government to evaluate processing of gas from the Elk-Antelope field by expanding the PNG LNG project. This would take advantage of synergies offered by expansion of an existing project to realize time and cost reductions that would benefit the PNG Treasury, the government’s holding in Oil Search, other shareholders and landowners.

Path to Completion

The ExxonMobil Transaction has been unanimously approved by the boards of both companies. The InterOil board unanimously recommends that InterOil shareholders approve the ExxonMobil Transaction.

The ExxonMobil Transaction will be implemented by way of a court-approved plan of arrangement under the Business Corporations Act (Yukon) and will require the approval of at least 66 2/3 percent of the votes cast by InterOil shareholders at a special meeting expected to take place in September, 2016.

In addition to InterOil shareholder and court approvals, the ExxonMobil Transaction is also subject to other customary conditions. Subject to obtaining the aforementioned approvals and satisfaction of closing conditions, the ExxonMobil Transaction is expected to close in September, 2016.

Further information regarding the transaction with ExxonMobil will be included in an information circular, which will be mailed to InterOil shareholders in due course. Copies of the key transaction documents for the ExxonMobil Transaction (being the arrangement agreement and the information circular) will be available online under InterOil’s corporate profile at www.sedar.com.

Oil Search Transaction

The InterOil board of directors, in consultation with its independent legal and financial advisors, determined that the ExxonMobil Transaction is superior to the previously announced transaction with Oil Search Limited (ASX:OSH, POMSoX: OSH) and so advised Oil Search on July 18, 2016. Immediately prior to entering into the arrangement agreement with ExxonMobil, InterOil terminated its previously announced arrangement agreement with Oil Search, and ExxonMobil is paying Oil Search the termination fee in accordance with the requirements of the Oil Search arrangement agreement on behalf of InterOil. The previously scheduled Special Meeting of Shareholders to vote for the approval of the Oil Search transaction has been cancelled.
