Mandatory Cash Offer for Global

Independent Directors of Global recommend Shareholders do not accept the O333ffer

Summary

§ Earlier today, Lyford announced that it had acquired a beneficial interest in Global through entering into an agreement to acquire 3,565,936 Global Shares, representing an interest of approximately 9.97 per cent. in Global, from the United States Marshals Service (the "USMS"), at a price of approximately US95.9 cents per Global Share (equivalent to approximately 59.2p per Global Share based on a closing mid exchange rate of US$1.62:£1 on 15 June 2011) (the "Acquisition"). Following completion of the Acquisition, Lyford will be interested in 8,897,236 Global Shares, representing approximately 24.88 per cent. of the issued share capital of Global.

§ Lyford is a company incorporated in the British Virgin Islands which is controlled by Brean. Brean also controls approximately 52.8 per cent. of HKN, a US company traded on the NYSE Amex, which in turn holds approximately 33.25 per cent. of Global's issued share capital.

§ Phyllis Quasha, who controls Brean, also controls Evansville, which in turn holds approximately 0.49 per cent. of Global's issued share capital.

§ In addition, Mr Mikel Faulkner, a director of 3both HKN and Global, holds approximately 0.66 per cent. of Global's issued share capital.

§ For the purposes of the Code, Phyllis Quasha, Brean, HKN, Evansville and Mikel Faulkner are deemed to be acting in concert with Lyford (together, the "Concert Party"). Immediately prior to the Acquisition, the Concert Party was beneficially interested in approximately 49.31 per cent. of Global's issued share capital. Following completion of the Acquisition, the Concert Party will be beneficially interested in approximately 59.28 per cent. of Global's issued share capital.

§ As a result of the Acquisition, under Rule 9 of the Code, the Concert Party is obliged to make a mandatory cash offer to acquire the entire issued share capital of Global not already owned by members of the Concert Party, conditional only upon HKN receiving such acceptances which will result in the Concert Party holding more than 50 per cent. of the Global Shares. Accordingly, following consultation with the Takeover Panel, HKN is announcing the terms of a mandatory cash offer to be made to the shareholders of Global at a price of 72p per share.

§ The Offer will comprise 72p in cash for each Global Share valuing the whole of Global's existing issued share capital at approximately £25.8 million.

§ The Offer Price is final and will not be increased.

§ The Independent Directors of Global recommend that Global Shareholders do not accept the Offer.

This summary should be read in conjunction with, and is subject to, the full text of the following announcement (including the Appendices). The Offer will be subject to the condition and the further terms set out in Appendix 1 of the following announcement and the terms to be set out in the Offer Document when issued. Appendix 2 contains the sources and bases of certain information used in this summary and in the following announcement. Appendix 3 contains definitions of certain terms used in this summary and the following announcement. Global Shareholders should carefully read the Offer Document (together with, if they hold their Global Shares in certificated form, the Form of Acceptance) in its entirety before making a decision with respect to the Offer.

Increased investment in Global Energy Development plc ("Global")

Mandatory Cash Offer for Global

Independent Directors of Global recommend Shareholders do not accept the Offer

1. Introduction

Earlier today, Lyford announced that it had acquired a beneficial interest in Global through entering into an agreement to acquire 3,565,936 Global Shares, representing an interest of approximately 9.97 per cent. in Global, from the United States Marshals Service (the "USMS"), at a price of approximately US95.9 cents per Global Share (equivalent to approximately 59.2p per Global Share based on a closing mid exchange rate of US$1.62:£1 on 15 June 2011) (the "Acquisition"). Completion of the Acquisition shall take place 90 days after execution of the Agreement, subject to agreement between the parties, conditional on various matters including that the warranties remain true and accurate. Following the completion of the Acquisition, Lyford will be interested in 8,897,236 Global Shares, representing approximately 24.88 per cent. of the issued share capital of Global.

Lyford is a company incorporated in the British Virgin Islands which is controlled by Brean. Brean also controls approximately 52.8 per cent. of HKN, a US company traded on the NYSE Amex, which in turn holds approximately 33.25 per cent. of Global's issued share capital.

Phyllis Quasha, who controls Brean, also controls Evansville, which in turn holds approximately 0.49 per cent. of Global's issued share capital.

In addition, Mikel Faulkner, a director of both HKN and Global, holds approximately 0.66 per cent. of Global's issued share capital.

For the purposes of the Code, Phyllis Quasha, Brean, HKN, Evansville and Mikel Faulkner are deemed to be acting in concert with Lyford (together, the "Concert Party"). Immediately prior to the Acquisition, the Concert Party was beneficially interested in approximately 49.31 per cent. of Global's issued share capital. Following completion of the Acquisition, the Concert Party will be beneficially interested in approximately 59.28 per cent. of Global's issued share capital.

As a result of the Acquisition, under Rule 9 of the Code, the Concert Party is obliged to make a mandatory cash offer to acquire the entire issued share capital of Global not already owned by members of the Concert Party conditional only upon HKN receiving such acceptances which will result in the Concert Party holding more than 50 per cent. of the Global Shares. Accordingly, following consultation with the Panel, HKN is announcing the terms of a mandatory cash offer to be made to the shareholders of Global at a price of 72p per share, being the highest price paid for a Global Share in the last 12 months by any member of the Concert Party.

2. The Offer

The Offer, which will be subject to the terms in Appendix 1 and subject to the condition set out below and in Appendix 1 and to be set out in the Offer Document and the Form of Acceptance, will be made on the following basis:

for each Global Share 72p in cash

The Offer is to be made by HKN as a mandatory cash offer in accordance with the Concert Party's obligations under Rule 9 of the Code. Accordingly, the Offer, which will not be increased, will be conditional only upon HKN receiving such acceptances which will result in the Concert Party holding more than 50 per cent. of the Global Shares.

The Offer values the whole of the existing issued share capital of Global at approximately £25.8 million. 

The Offer Price represents a discount of approximately 7.7 per cent. to the Closing Price of 78p of a Global Share on 15 June 2011, the trading day immediately preceding the date of this announcement. 

The Global Shares will be acquired by HKN, pursuant to the Offer, fully paid with full title guarantee and free from all liens, charges, encumbrances, equitable interests, pre-emption rights and other interests and rights of whatsoever nature and together with all rights now or hereafter attaching thereto, including the right to receive and retain in full all dividends and other distributions (if any) declared, paid or made after the date of this announcement.

The Offer Document and (in the case of Global Shareholders who hold their Global Shares in certificated form) the Form of Acceptance containing the full terms and condition of the Offer will be posted to Global Shareholders (other than Global Shareholders in a Restricted Jurisdiction) in due course.

3. Views of the Independent Directors of Global

While the Independent Directors recognise that the making of the Offer is a requirement of Rule 9 of the Code, the Independent Directors consider that the Offer materially undervalues Global. The Independent Directors, who have been so advised by Matrix, do not therefore consider the terms of the Offer to be fair and reasonable. In providing advice to the Independent Directors, Matrix has taken into account the commercial assessments of the Independent Directors.

Accordingly, the Independent Directors intend to unanimously recommend that Global Shareholders do not accept the Offer. The Independent Directors do not intend to accept the Offer in respect of their own shareholdings amounting, in aggregate, to 221,985 Global Shares (representing 0.62 per cent. of Global's issued share capital).

Notwithstanding the above and recognising that the Concert Party, in particular HKN, has since Global's admission to AIM had a considerable degree of influence over Global (albeit that the Concert Party's aggregate interest prior to the Acquisition had fallen to below 50 per cent. of Global's issued share capital), the Independent Directors consider that Global Shareholders should be aware of the implications of completion of the Acquisition. In particular, Global Shareholders should note that as a result of completion of the Acquisition and/or the Offer, the Concert Party will hold a majority of Global's issued share capital and therefore, have sufficient rights to ensure that ordinary resolutions are passed, as well as the ability to block resolutions of which it does not approve. In addition, for so long as the Concert Party holds more than 50 per cent. of the voting rights of Global, members of the Concert Party will also be free to increase their shareholding in Global through acquisitions from Global Shareholders without any obligation under the Code to make a further offer to all Global Shareholders (other than in circumstances where Note 4 of Rule 9.1 of the Code might apply).

4. Information on Global

Global's portfolio covers the countries of Colombia and Peru and comprises a base of production, developmental drilling and workover opportunities and several exploration projects.

For the year ended 31 December 2010, Global had revenues of approximately US$23.8 million and as at that date had net assets of approximately US$79.8 million.

5. Information on HKN and its concert parties

HKN is an energy company, whose shares are listed on the New York Stock Exchange, engaged in the development and production of crude oil, natural gas and coalbed methane assets and in the active management of energy-based investments.

Susan V. Demers and Andrea J. Douglas are the directors of Vicali. Mrs Phyllis Quasha is the beneficial owner of Brean.

6. Financing of the Offer and cash confirmation

Full acceptance of the Offer will result in the payment by HKN of approximately £11.21 million in cash, on the assumption that only options that have vested with exercise prices below 72p are exercised and accept the Offer and taking account the irrevocable undertakings given by Mikel Faulkner and Stephen Voss to not accept the Offer in respect of any Global Shares issued as a result of exercise of their options.

The aggregate cash consideration payable by HKN will be financed from the existing cash resources of HKN.

Merchant Securities, financial adviser to HKN, is satisfied that sufficient resources are available to HKN to satisfy the cash consideration payable to Global Shareholders in the event of full acceptance of the Offer.

7. Expected Timetable

It is intended that the Offer Document and Form of Acceptance containing the full terms and the condition of the Offer will be despatched to the Global Shareholders as soon as practicable and in any event within 28 days. The Offer Document will contain full details of the expected timetable and will specify the necessary actions to be taken by Global Shareholders.

8. Management, employees and locations

The existing employment rights and terms and conditions of employment, including pension obligations, of employees of Global will continue to be safeguarded following the Offer. HKN does not currently intend to make any material change in the conditions or location of employment of Global employees, nor does it currently intend to change the location of Global's places of business, the composition of Global's Board of Directors, or to redeploy Global's fixed assets.

9. Global trading on AIM

HKN intends that the admission to trading of Global Shares on AIM will continue following the Offer.

10. Disclosure of interests in Global and confirmation of Opening Position Disclosure

Immediately prior to the Acquisition, HKN and its concert parties were beneficially interested in 17,636,624 Global Shares, representing approximately 49.31 per cent. of Global's issued share capital.

These comprise the following shareholdings:

* In addition, Mikel Faulkner holds 1,890,000 options over Global Shares.

Irrevocable undertakings

The following directors of Global have given irrevocable undertakings to HKN that they will not accept the Offer in respect of options held by them which have vested:

Save for the interests disclosed above, neither HKN nor any of HKN's directors nor, so far as HKN is aware, any party acting in concert with HKN for the purposes of the Offer:

(i) has any interest in or right to subscribe for any relevant securities of Global; or

(iv) has procured any irrevocable undertaking or letter of intent in respect of any relevant securities of Global.

There are no arrangements of the kind referred to in Note 11 on the definition of acting in concert in the Code which exist between HKN, HKN's directors (or, so far as HKN is aware, any party acting in concert with HKN for the purposes of the Offer) and any other person in relation to any relevant securities of Global.

HKN confirms that it is on the date of this announcement making an Opening Position Disclosure (as defined in the Code), which discloses the details required to be disclosed by it and all other persons deemed to be acting in concert with it under Rule 8 of the Code.
