NOTICE OF CONSENT SOLICITATION

**** IMPORTANT REMINDER ****

Dear Hyperdynamics Corporation Stockholder:

By now, you should have received your proxy materials seeking a written consent of the majority of the holders of the common stock (the “Common Stock”) of Hyperdynamics Corporation (the “Company”) to amend the Company’s certificate of incorporation to effectuate a reverse split of the Common Stock of between one-for-two (1:2) and one-for-six (1:6) (the “Reverse Stock Split Proposal”). Our records indicate you have not yet voted your shares at the time of the mailing of this reminder letter. As such, our board of directors has elected to extend the date you must vote your shares until August 10, 2017.

Each stockholder’s vote is extremely important because the proposal to approve the Reverse Stock Split Proposal requires the favorable vote of a majority of the issued and outstanding shares of Common Stock in order to be approved. Not voting has the same effect as a vote against this important proposal. Note that if you are a beneficial owner and do not instruct your broker, bank or other nominee how to vote your shares, your broker, bank or other nominee can use its discretion to vote your shares with respect to this matter.

PLEASE CAST YOUR VOTE TODAY. The fastest and easiest way to vote is by telephone or on the Internet. Instructions on how to vote your shares by telephone or on the Internet are attached below and are provided on the proxy card enclosed with this letter. Alternatively, you may sign and return the enclosed voting form in the envelope provided.

YOUR VOTE IS IMPORTANT

WE URGE YOU TO EXERCISE YOUR RIGHT TO VOTE TODAY.

If you sign and return the enclosed proxy card without indicating a different choice, your shares will be voted FOR the proposal. Important information about the Reverse Stock Split Proposal is contained in the proxy statement dated July 11, 2017 which was previously mailed to you and which we urge you to read.

On behalf of your Board of Directors, thank you for your cooperation and continued support.

Sincerely,

/s/ Jason Davis

Jason Davis
Chief Financial Officer
