Exhibit 99.5

*** Vote Today FOR the ExxonMobil Transaction ***

August 19, 2016

Dear InterOil Shareholders,

On July 21, 2016, InterOil entered into a definitive agreement under which ExxonMobil agreed to acquire the company in a transaction valued at more than $2.5 billion. Your Board of Directors has unanimously recommended that InterOil shareholders vote FOR the transaction in connection with a Special Meeting scheduled to be held on September 21, 2016.

VOTE FOR THE EXXONMOBIL TRANSACTION TO REALIZE

COMPELLING VALUE FOR YOUR INVESTMENT IN INTEROIL

A vote for the ExxonMobil transaction is a vote FOR:

• A Material and Immediate Premium: For each share of InterOil stock held, InterOil shareholders will receive $45 worth of ExxonMobil common shares (calculated based on a 10-day VWAP) and a Contingent Resource Payment (“CRP”). The share consideration represents a premium of 42.2% to InterOil’s closing price on May 19, 2016 (the day prior to the announcement of the Oil Search transaction).¹

• Significant Potential Upside in PRL 15 Resource through the CRP: The CRP provides a cash payment to shareholders of ~$7.07 for each share they hold for each incremental certified tcfe of PRL 15 2C resource above 6.2 tcfe, up to a maximum of 10 tcfe of certified resource.

• Exposure to Future Value: InterOil shareholders who retain their ExxonMobil shares will benefit from ownership in the world’s preeminent energy company, which provides a larger asset base, a current 3.2 percent dividend yield and 34 consecutive years of dividend growth, and is listed on the NYSE.

To realize the immediate benefit of the ExxonMobil transaction, we encourage you to vote FOR the ExxonMobil transaction. Vote TODAY online, by telephone or by completing, signing and dating the enclosed proxy, and returning it in the enclosed postage-paid envelope by 12:00PM ET on September 19, 2016.

THE TRANSACTION WITH EXXONMOBIL DELIVERS COMPELLING VALUE

Together, the base consideration of $45 worth of ExxonMobil shares (calculated based on a 10-day VWAP) per each InterOil share and the CRP represent a compelling value for InterOil shareholders. The table below illustrates the range of potential outcomes of the Elk-Antelope resource estimate:

¹  Represents potential future payment at given certified resource level; not discounted to present value.

²  Based on InterOil’s closing price of US$31.65 per share as of May 19, 2016, prior to announcement of the Oil Search transaction.

³  Based on InterOil’s 1-month VWAP up to and including May 19, 2016 of US$31.88 per share.

⁴  Based on InterOil’s 3-month VWAP up to and including May 19, 2016 of US$30.37 per share.

The CRP will be deposited into escrow at closing and will be paid to former InterOil shareholders based on and following the completion of the interim resource certification process in accordance with InterOil’s existing Share Purchase Agreement with Total SA, which will include the Antelope-7 appraisal well that is scheduled to be drilled later in 2016. Importantly, the CRP is structured so ExxonMobil’s interests are aligned with the interests of InterOil shareholders to ensure a robust and accurate certification process.
