As part of the placing, Henderson will receive 12,000,000 warrants with a deemed exercise price of 2.75p per share (the "Warrants").

The Warrants are subject to a cashless exchange right, exercisable at the discretion of the holder but not prior to 18 December 2012. In addition, the Company is pleased to announce that it has signed Heads of Terms with Darwin Strategic Limited ("Darwin") for the provision of a �10 million Equity Financing Facility ("EFF"), over a period of 36 months.

The subscription price of any draw down of the EFF will be the average of the three lowest daily closing bid prices during the 15 trading days immediately following a draw down notice.

Any exercise of the draw down shall have a volume commitment of a minimum of four times the average daily volume traded in Magnolia shares, as reported on Bloomberg for AIM during the 15 days prior to activation, subject to certain restrictions which are yet to be finalised. Darwin is a majority owned subsidiary of Henderson Global Investors Alphagen Volantis fund.

A further announcement will be made describing the terms of the EFF in more detail, once the final agreement has been entered into, expected to be no later than 20 July 2012. The net proceeds of the Fundraising will be used to further expedite the Companys existing growth and investment strategy as set out at the time of Admission in November 2011. Following the recent announcements made by the Company, it intends to seek out further acquisitions of both producing and non-producing interests in the highly productive Bakken / Three Forks Sanish hydrocarbon formations in North Dakota as well as in the substantial and proven Woodford/Hunton reservoirs in Oklahoma and the oil rich Mississippi Formation located in Oklahoma.

In addition, the Company is reviewing a number of additional well proposals and will be participating in new drilling as appropriate. Rita Whittington, COO of Magnolia Petroleum, said, "We are extremely pleased to welcome Henderson Global to the share register of Magnolia as an institutional investor and that we have reached Heads of Terms in respect of a �10 million financing facility.

Our participation in the drilling of wells, both in number and percentage interest is on the increase.

The fundraising will enable us to aggressively participate in the development of prospects in which we have an interest."

Application will be made for the admission of the Subscription Shares to trading on AIM and it is expected that admission will occur and that dealings will commence at 8.00 a.m.

on 18 July 2012.
