Dear Shareholder and/or Optionholder,

Your Enegex Shares (ASX Code “ENX”) and/or Enegex Options (ASX Code “ENXO”).

I am pleased to advise that Enegex N L (“Enegex”) has been approved for admission to the Official List of ASX.

Accompanying this letter is:

1. An Information Memorandum (“ IM ”) lodged with ASX Limited (“ ASX ”) in support of Enegex’s application for Listing on ASX. This IM has also been released to ASX by Moby Oil & Gas Limited (“ Moby ”) and can be accessed on the ASX website under ASX Code MOG . A copy of the IM will also be able to be accessed on the ASX website under Enegex’s ASX Code ENX . You should read this IM before deciding to deal in any Enegex securities.

2. A Transaction Confirmation Statement setting out detail of the ordinary shares in Enegex (“ Enegex Shares ”) and/or the options to acquire ordinary shares in Enegex (“ Enegex Options ”) to which you became entitled under the schemes of arrangement entered into between Moby and its shareholders (“ Share Scheme ”) and Moby and its optionholders (“ Option Scheme ”). The basis of your entitlement to Enegex Shares and/or Enegex Options is set out in that Transaction Confirmation Statement.

Your Moby Shares were cancelled on 30 September 2013 in accordance with the provisions of the Share Scheme and the reduction of capital resolution passed at the general meeting of Moby’s shareholders held in conjunction with the Scheme meetings. Your listed Moby Options expired on 30 June 2013 in accordance with their terms of issue and any unlisted Moby Options you may have held have also been cancelled under the Option Scheme on 30 September 2013.

You are referred to the general taxation advice contained in the taxation report from Blaze Acumen dated 13 December 2012 (“ Tax Report ”) contained in the scheme booklet issued in relation to the schemes (“ Scheme Booklet ”) which advised that the cancellation of your Moby Shares or Moby Options are each C2 Capital Gains Tax (“ CGT ”) events and a disposition of those shares and/or options. A copy of the Scheme Booklet has been lodged with ASX and may be accessed under Enegex’s ASX Code ENX. You may access the Blaze Acumen Tax Report by accessing that document.

You should note that there are no CGT rollovers available in respect of the cancellation of the Moby shares and/or Moby options and that, if you held your Moby shares or Moby options on capital account, you will be required to calculate, and bring to account, any capital gain or capital loss on the cancellation of those shares or the expiry (on 30 June 2013) of any listed Moby options you held or the cancellation on 30 September 2013 of any unlisted options you held. The consideration that you receive on the disposal of your Moby shares is the Enegex Shares and the market value of those Enegex Shares will be the amount of that consideration. This is, perhaps, best determined by having regard to the Volume Weighed Average Price (“ VWAP ”) of the Enegex Shares and of the Enegex Options following commencement of trading on ASX.

Enegex will determine the relevant VWAP for Enegex Shares and Enegex Options subsequent to commencement of trading of each of those securities on ASX and will make a release to ASX containing that information for your benefit. You should access that release for use by you in preparation of your relevant tax returns.

If a gain results on disposition of your Moby Shares or Moby Options you may, depending on your profile for tax purposes, be entitled to the 50% CGT discount if you have held your Moby Shares or Moby Options for 12 months or more.

If you are a non/resident shareholder or optionholder you are unlikely to suffer any CGT consequences in Australia on the disposal of your Moby Shares or Moby Options. You should, however, seek your own tax advice as consequences of the schemes in the country in which you are resident for tax purposes.

If you held Moby Shares or Moby Options as trading stock the CGT rules referred to above may not apply and you should seek your own independent tax advice.

Finally, you should note that the contents of this letter are of a general nature and do not constitute taxation advice specific to you and that you should seek your own independent taxation advice as to the taxation consequences of the above matters as they relate to your circumstances.

Yours faithfully
