This Notice of Meeting is accompanied by the Information Circular and forms of proxy and the Information Circular contains additional information relating to matters to be considered at the Meeting.

InterOil has set August 10, 2016 as the record date (the “Record Date”) for the determination of the Securityholders entitled to receive notice of and to vote at the Meeting.

Securityholders may attend the Meeting in person or may be represented by proxy. Registered Shareholders, Option Holders and RSU Holders are encouraged to complete, sign, date, and return the accompanying applicable form of proxy so that such Securityholders’ Common Shares, Options or RSUs, as applicable, can be voted at the Meeting (or at any adjournments or postponements thereof) in accordance with such Securityholders’ instructions, whether or not you plan to attend. To be effective, the enclosed proxy must be received by Computershare Investor Services Inc. (8^th Floor, 100 University Avenue, Toronto, Ontario, Canada, M5J 2Y1) or MacKenzie Partners, Inc.

Your Common Shares, Options or RSUs will be voted in accordance with your instructions as indicated on the form of proxy or, if no instructions are given on the form of proxy, the proxy holder will vote “FOR” the Arrangement Resolution.

Non-registered Shareholders who hold their Common Shares through a broker, investment dealer, bank, trust company, custodian, nominee or other intermediary, should carefully follow the instructions of their intermediary to ensure that their Common Shares are voted at the Meeting in accordance with such Shareholder’s instructions, to arrange for their intermediary to complete the necessary transmittal documents and to ensure that they receive payment for their Common Shares if the Arrangement is completed.

Pursuant to the Interim Order, registered Shareholders as of the Record Date have been granted the right to dissent in respect of the Arrangement Resolution. If the Arrangement becomes effective, a registered Shareholder as of the Record Date who dissents in respect of the Arrangement Resolution (each a “Dissenting Shareholder”) is entitled to be paid the fair value of such Dissenting Shareholder’s Common Shares, provided that such Dissenting Shareholder has delivered a written objection to the Arrangement Resolution to InterOil not later than 4:00 p.m. (Eastern Time) on September 19, 2016, being two (2) business days preceding the Meeting (or, if the Meeting is postponed or adjourned, two (2) business days preceding the date of the postponed or adjourned Meeting) and has otherwise complied strictly with the dissent procedures described in the Information Circular, including the relevant provisions of section 193 of the YBCA, as modified by the Interim Order and the Arrangement. Beneficial owners of Common Shares registered in the name of a broker, investment dealer or other intermediary who wish to dissent should be aware that only registered owners of Common Shares as of the Record Date are entitled to dissent. Failure to comply strictly with the dissent procedures described in the Information Circular will result in the loss of any right of dissent. These rights are described in detail in the accompanying Information Circular under the heading “Dissent Rights”. The text of section 193 of the YBCA, which is relevant in any dissent proceeding, is set forth in Schedule G to this Information Circular.
