LONDON, February 6, 2011 /PRNewswire-FirstCall/ --

- Not for Release, Publication or Distribution in, Into or From Any Jurisdiction Where to do so Would Constitute a Violation of the Relevant Laws of Such Jurisdiction

    - Following the announcement on 10 December 2010 of a recommended cash
    offer for Regal, Energees Investments (the principal holding company of
    the Smart Holding Group) and Regal are pleased to announce that they
    have reached agreement on the terms of a revised, increased, recommended
    partial cash offer to be made by Energees Management.

    - The revised offer will be structured as a partial offer for up to
    224,446,485 Regal Shares (representing approximately 70 per cent. of
    the fully diluted share capital of the Company) at 38 pence in cash per
    Regal Share (the Increased Partial Offer).

    - The terms of the Increased Partial Offer value Regal's fully diluted
    share capital at approximately GBP121.8 million and the Regal Shares
    subject to the Increased Partial Offer at approximately GBP85.3 million.

    - The Increased Partial Offer allows those Regal Shareholders, who accept
    in respect of all of their Regal Shares, the potential for a full exit at
    38 pence in cash per Regal Share (although acceptances in respect of
    more than 70 per cent. of a Shareholder's Regal Shares may be subject to
    scaling down as set out in paragraph 2 of this Announcement).

    - The consideration of 38 pence per Regal Share under the
    terms of the Increased Partial Offer represents a:

      - 204% premium to the closing price of 12.5 pence per Regal Share on 24
      November 2010, being the last business day before the commencement of
      the Offer Period;

      - 147% premium to the average closing price of 15.4 pence per Regal
      Share for the one month period prior to the commencement of the Offer
      Period; and

      - 58% premium to the offer price of 24 pence per Regal Share under the
      Original Offer.

    - The Increased Partial Offer will also allow those Regal Shareholders,
    who do not want to accept the Increased Partial Offer in respect of all
    of their Regal Shares, to retain an ongoing equity interest in
    Regal in respect of some or all of their holding.

    - The Increased Partial Offer has a clearly defined timetable, is not
    subject to Ukrainian anti-trust clearance (which was received by
    Energees Management on 20 January 2011) and will enable (subject to the
    Increased Partial Offer being declared wholly unconditional on 20
    February 2011) cash consideration to be despatched to Regal Shareholders
    on or around 8 March 2011 (once any scaling down exercise has been
    completed).

    - Smart Holding Group is one of the largest, diversified groups of
    companies in Ukraine and brings extensive experience of operating
    in Ukraine and in the natural resources sector.

    - The Increased Partial Offer will result in the Smart Holding Group
    obtaining majority ownership of Regal and will give local,
    Ukraine-based shareholder support to Regal management, as well as
    providing value and certainty to Regal Shareholders.

    - The Regal Directors, who have been so advised by BofA Merrill Lynch,
    consider the terms of the Increased Partial Offer to be fair
    and reasonable. The background to and reasons for the Regal Directors'
    recommendation are summarised in paragraph 6 of this Announcement. In
    providing its advice, BofA Merrill Lynch has taken into account the
    commercial assessments of the Regal Directors.

    - The Regal Directors have terminated Regal's discussions with
    Heamoor and Geo-Alliance, having concluded that the Increased Partial
    Offer is the best and only firm option currently available to Regal
    Shareholders and on the basis that the Increased Partial Offer delivers
    greater certainty of value for Regal Shareholders than their proposed
    transaction or Regal remaining an independent quoted entity without the
    majority ownership of Energees Management.

    - The Increased Partial Offer Document is being published, and will be
    posted to Regal Shareholders (other than persons in a Restricted
    Jurisdiction), today together with the Approval Form and New Form of
    Acceptance.

    - Energees Management has received irrevocable undertakings to accept
    and approve the Increased Partial Offer from certain Regal Shareholders,
    as well as Regal Directors, in respect of 42,509,411 Regal Shares,
    representing approximately 13.35 per cent. of Regal's existing issued
    ordinary share capital. 15,484,800 of these Regal Shares, representing
    approximately 4.86 per cent. of the existing issued ordinary share
    capital of Regal, relate to long derivative contracts in respect of
    which the holder has undertaken to use reasonable endeavours to procure
    (so far as it is able) acceptance and approval of the Increased Partial
    Offer. Further details are set out below.

    - The Increased Partial Offer must be declared unconditional as to
    acceptances by 20 February 2011 (unless the Panel otherwise consents)
    and Regal Shareholders are therefore urged to return their New Forms of
    Acceptance and Approval Forms as soon as possible.

Commenting on the Increased Partial Offer, Alexey Pertin, Director of Energees Investments and CEO of the Smart Holding Group, stated that:

"Our Increased Partial Offer is a carefully considered means of providing all shareholders a complete solution today.

Those seeking ongoing equity exposure can select equity and maximise their ongoing stake in Regal, knowing exactly what they are investing in - a re-energized Regal with the committed local country backing of Energees Management - without taking risk on assets, strategy and management which may be unfamiliar to Regal Shareholders.

In addition, with the 147% one month average premium available under the Increased Partial Offer, Energees Management is providing Regal shareholders the option to enjoy a highly attractive and quickly realisable cash exit (potentially for up to 100% of their shareholding) at highly compelling valuation levels.

We are excited about supporting Regal in the next stage of its journey and look forward to working to realise value for all stakeholders, today, tomorrow and in the future."

Keith Henry, Chairman of Regal, commented:

"Against the background of operational, legal and funding challenges faced by the Company, your Board is pleased to have reached a much improved agreement with Energees Management that allows Regal Shareholders to receive a substantially increased cash element of consideration as well as retaining the option of maintaining equity exposure in Regal.

Based on work completed to date in connection with the Geo Proposal by Regal and its advisers, and the Board's assessment of the certainty of being able to finalise all required workstreams and to announce a binding transaction with Heamoor and Geo-Alliance, the Board of Regal has concluded that the Increased Partial Offer represents a superior proposition with respect to certainty of value by comparison to the Geo Proposal, that the Increased Partial Offer is the best and only firm option currently available to Regal Shareholders and therefore intends unanimously to recommend shareholders to accept and approve the Increased Partial Offer"

Overseas Jurisdictions

The distribution of this Announcement in jurisdictions other than the UK and the availability of the Increased Partial Offer to Shareholders who are not resident in the UK may be affected by the laws of relevant jurisdictions. Therefore any persons who are subject to the laws of any jurisdiction other than the UK or Shareholders who are not resident in the UK will need to inform themselves about, and observe, any applicable requirements. Except as required by applicable law, copies of this Announcement are not being, and may not be, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction.

In particular, the Increased Partial Offer is not, unless decided otherwise by Energees Management, being made in or into, and is not capable of acceptance in or from, any Restricted Jurisdiction. Persons receiving this Announcement (including, without limitation, custodians, nominees or trustees) should observe these restrictions and should not send or distribute documents in or into any Restricted Jurisdiction.

This Announcement has been prepared for the purpose of complying with English law and the Takeover Code and the information disclosed may not be the same as that which would have been disclosed if this Announcement had been prepared in accordance with the laws of jurisdictions outside the UK.

US Holders should note that the Increased Partial Offer relates to the shares of a UK company, is subject to UK disclosure requirements (which are different from those of the United States) and that the Increased Partial Offer Document and any other documents relating to the Increased Partial Offer have been or will be prepared in accordance with the Takeover Code and the UK disclosure requirements, format and style, all of which differ from those in the United States.

The Increased Partial Offer will be made in the United States pursuant to applicable US tender offer and securities laws and otherwise in accordance with the requirements of the Takeover Code. Accordingly, the Increased Partial Offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, offer timetable, settlement procedures and timing of payments that are different from those applicable under US domestic tender offer procedure and law.

The receipt of cash pursuant to the Increased Partial Offer by a US Holder may be a taxable transaction for United States federal income tax purposes and under applicable United States state and local, as well as foreign and other, tax laws. Each Shareholder is urged to consult his independent professional adviser immediately regarding the tax consequences of acceptance of the Increased Partial Offer.

It may be difficult for US Holders to enforce their rights and claims arising out of United States federal securities laws, since Energees Management and Regal are located in countries other than the United States, and some or all of their officers and directors may be residents of countries other than the United States. US Holders may not be able to sue a non-United States company or its officers or directors in a non-United States court for violations of United States securities laws. Further, it may be difficult to compel a non-United States company and its affiliates to subject themselves to a United States court's judgement.

To the extent permitted by applicable law, in accordance with normal UK practice and pursuant to Rule 14e-5(b) of the US Exchange Act, Energees Management or its nominees, or its brokers (acting as agents) or their respective affiliates, may from time to time make certain purchases of, or arrangements to purchase Regal Shares outside of the United States, other than pursuant to the Increased Partial Offer, until the date on which the Increased Partial Offer becomes effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Such purchases or arrangements to purchase will comply with all applicable UK rules, including the Takeover Code, the rules of the London Stock Exchange and Rule 14e-5(b) of the US Exchange Act to the extent applicable. Any information about such purchases will be disclosed as required in the UK, will be reported to the Regulatory News Service of the London Stock Exchange and will be available on the London Stock Exchange website at http://www.londonstockexchange.com/prices-and-news/prices-news/home.htm.

Energees Investments and Regal Petroleum Announce Increased Recommended Partial Cash Offer

1 Introduction

Following the announcement on 10 December 2010 of a recommended cash offer for Regal, Energees Investments and Regal are pleased to announce that they have reached agreement on the terms of a revised, increased, recommended partial cash offer to be made by Energees Management.

The revised offer will be structured as a partial cash offer for up to 224,446,485 Regal Shares (representing approximately 70 per cent. of the fully diluted share capital of the Company) at 38 pence per Regal Share (the Increased Partial Offer).

The consideration of 38 pence per Regal Share under the terms of the Increased Partial Offer represents a:

    - 204% premium to the closing price of 12.5 pence per Regal Share on 24
    November 2010, being the last business day before the commencement of
    the Offer Period;

    - 147% premium to the average closing price of 15.4 pence per Regal Share
    for the one month period prior to the commencement of the Offer Period;
    and

    - 58% premium to the offer price of 24 pence per Regal Share under the
    Original Offer.

2 The Increased Partial Offer

The Increased Partial Offer, which will be subject to the Conditions and further terms set out in Appendix I to the Original Offer Document as amended by this Announcement, the Increased Partial Offer Document, the Approval Form and the New Form of Acceptance, will be made on the following basis:

    for each Regal Share           38 pence in cash

The Increased Partial Offer values the Company's fully diluted ordinary share capital at approximately GBP121.8 million and the Regal Shares subject to the Increased Partial Offer at approximately GBP85.3 million.

Regal Shareholders may accept the Increased Partial Offer in respect of any number of their Regal Shares or none at all. Subject to the Increased Partial Offer becoming unconditional in all respects, acceptances will be met in full to the extent that they are for up to 70 per cent. (the Relevant Percentage) of an accepting Regal Shareholder's registered holding of Regal Shares at the Record Date. Acceptances in excess of this amount will be met to the extent that other Regal Shareholders do not accept the Increased Partial Offer or accept in respect of less than their Relevant Percentage. Regal Shares tendered in excess of those representing the Relevant Percentage of an accepting Regal Shareholder's holding at the Record Date will be accepted from each Regal Shareholder in the same proportion to the number tendered to the extent necessary to enable Energees Management to acquire 224,446,485 Regal Shares pursuant to the Increased Partial Offer.

In the event that scaling down, as described above, is required in respect of any accepting Regal Shareholders, Energees Management will make an announcement stating the basis of such scaling down by 9.00 a.m. on the second business day following the closing of the Increased Partial Offer.

Regal Shareholders who have already accepted the Original Offer in respect of some or all of their Regal Shares will be deemed to have accepted the Increased Partial Offer in respect of the same number of Regal Shares (subject to scaling down on the basis set out above to the extent this exceeds the Relevant Percentage of their holding at the Record Date). Such Shareholders need not complete a New Form of Acceptance or submit a further electronic instruction unless they wish to reduce the number of Regal Shares the subject of their acceptance, however if they approve of the Increased Partial Offer they should complete and return an Approval Form (once received by them) in accordance with the procedures set out in the Increased Partial Offer Document and paragraph 14 below (whether they hold their Regal Shares in certificated or uncertificated form).

The 224,446,485 Regal Shares for which the Increased Partial Offer is being made represent approximately 70 per cent. of the fully diluted share capital of the Company. The Increased Partial Offer will extend, subject to the Conditions and further terms set out in the Original Offer Document as amended by this Announcement, the Increased Partial Offer Document, the Approval Form and the New Form of Acceptance, to any new Regal Shares unconditionally allotted or issued fully paid (or credited as fully paid) on or after the date the Increased Partial Offer is made and prior to the Record Date.

Regal Shareholders should note that the Relevant Percentage has been calculated on the basis of the fully diluted share capital of the Company (being 320,637,836 Regal Shares) and it may change slightly if the number of Regal Shares in issue on the Record Date differs from this number.

The Regal Shares will be acquired pursuant to the Increased Partial Offer fully paid with full title guarantee and free from all liens, charges, equitable interests, encumbrances, rights of pre-emption and any other third party rights or interests of any nature whatsoever and together with all rights now and hereafter attaching to them, including, without limitation, the right to receive and retain all dividends and other distributions (if any) declared, made or paid in respect of the Regal Shares on or after 10 December 2010.

In the event that the Increased Partial Offer becomes unconditional in all respects, Energees Management will hold Regal Shares carrying more than 50 per cent. of the voting rights of Regal, and Energees Management will be free (subject to Rule 36.3 of the Takeover Code) to acquire further Regal Shares without incurring any obligation under Rule 9 of the Takeover Code to make a general offer.

Following a successful partial offer, Rule 36.3 of the Takeover Code prevents the offeror, any person acting in concert with the offeror in the course of the partial offer and any person who is subsequently acting in concert with any of them from acquiring any interest in the shares of the offeree during a period of 12 months after the end of the offer period without the consent of the Panel.

Under Rule 36.5 of the Takeover Code, approval of the Increased Partial Offer by Regal Shareholders is required and the Increased Partial Offer will be conditional upon such approval being obtained. For this condition to be satisfied, Regal Shareholders, who are independent of Energees Management and persons acting in concert with Energees Management, and represent more than 50 per cent. of the voting rights in Regal must give their approval to the Increased Partial Offer. If such approval is not obtained, the Increased Partial Offer will lapse. All Regal Shareholders who approve of the Increased Partial Offer (whether or not they wish to accept the Increased Partial Offer and whether they hold their Regal Shares in certificated or uncertificated form) should therefore complete and return the Approval Form (once received by them) in accordance with procedures set out in the Increased Partial Offer Document and paragraph 14 below.

3 Background to and reasons for the Increased Partial Offer

Energees Management has considered the feedback it has received from Regal Shareholders and has formulated the partial offer structure in order that Regal Shareholders have the option to receive a combination of cash and retain part of their holding in Regal Shares. In addition, Regal Shareholders may elect to accept more cash or retain more shares, although elections for increased amounts of cash are subject to being scaled down as referred to above and the ability for a Regal Shareholder to retain more than 30 per cent. of its shareholding is subject (inter alia) to sufficient acceptances being received in aggregate to satisfy the acceptance condition set out in paragraph 13 below.

The price of 38 pence per Regal Share under the Increased Partial Offer means that Regal Shareholders can receive a highly compelling cash element of consideration representing a:

    - 204% premium to the closing price of 12.5 pence per Regal Share on 24
    November 2010, being the last business day before the commencement of
    the Offer Period;

    - 147% premium to the average closing price of 15.4 pence per Regal Share
    for the one month period prior to the commencement of the Offer Period;
    and

    - 58% premium to the offer price of 24 pence per Regal Share under the
    Original Offer.


    In addition, the terms of the Increased Partial Offer are such that:

    - Regal Shareholders are able to maintain a meaningful stake in Regal of
    30 per cent. of their current shareholding, and a higher level than this
    should they wish to do so (subject, inter alia, to sufficient acceptances
    being received in aggregate to satisfy the acceptance condition set out
    in paragraph 13 below) and in either scenario, therefore, share in the
    performance of Regal under the new majority ownership of Energees
    Management who are familiar with conducting business in Ukraine;

    - as existing shareholders in Regal, Regal Shareholders know the business
    and assets to which their shareholding relates and can ascribe value to
    their shareholding; and

    - as set out below, Regal's admission to trading on AIM will be
    maintained, preserving the corporate governance and minority shareholder
    protections for Regal Shareholders.

Finally, the partial offer structure also enables Regal Shareholders to exit Regal for cash via the Increased Partial Offer (for at least 70 per cent. of their shareholding) and/or, subject to market liquidity at the relevant time, to continue to be able to do so through subsequent sales of any retained interest in Regal Shares following completion of the Increased Partial Offer, as Regal will continue to be admitted to trading on AIM.

It should also be noted that Ukrainian anti-trust clearance was received by Energees Management on 20 January 2011, meaning that condition 1(b) to the Original Offer and the Increased Partial Offer is now satisfied.

With regard to the proposals announced on 18 January 2011 by Regal to be made by Heamoor Limited (Heamoor) and Geo-Alliance Oil-Gas Public Limited (Geo-Alliance), the Increased Partial Offer compares very favourably:

    - the cash consideration per Regal Share available to Regal
    Shareholders is 13 pence more than the 25 pence per Regal Share
    available to Shareholders under the proposed purchasing commitment
    or proposed pre-conditional cash offer as set out in the announcement on
    18 January 2011 as referred to above (which represents a premium of 52%);
    - the strategy for the Regal Group is known under the terms of the
    Increased Partial Offer (see paragraph 4 below);
    - the Heamoor potential offer includes, as part of the proposed
    reverse takeover of Regal, a contribution of Geo-Alliance assets which
    may be unfamiliar to Regal shareholders and the value of which may, in
    Energees Management's view, not be certain, as, notwithstanding published
    data on these assets, such data depends on a number of assumptions, for
    instance as to oil price and costs, which, in Energees Management's view,
    are uncertain;
    - the Heamoor potential offer is more complex than the Increased
    Partial Offer and is subject to a number of conditions, including
    anti-trust approval(s) of the Anti Monopoly Committee of Ukraine; and
    - in order for Heamoor/Geo-Alliance to present its proposals to
    shareholders, considerable documentation will need to be agreed, approved
    and published, and a general meeting of Regal Shareholders will need to
    be held, both of which could contribute to an extended timetable when
    compared to the timetable of the Increased Partial Offer. The Increased
    Partial Offer has a clearly defined timetable and is available for
    acceptance by Regal Shareholders until 20 February 2011 and, subject to
    the Increased Partial Offer being declared wholly unconditional on 20
    February 2011, cash consideration will be despatched to Regal
    Shareholders on or around 8 March 2011 (once any scaling down exercise
    has been completed).

4 Strategy and Board composition

Energees Management, as part of the Smart Holding Group, has in place a clear strategy for supporting Regal's continued development.

Financial Support and Capital Investment

As majority owner of Regal following the Increased Partial Offer becoming, or being declared, wholly unconditional, Energees Management will be committed to developing the Regal Group. Energees Management recognises that in order to develop the Regal business, investment of further capital will be required. While Energees Management has made no firm decision on the form of such investment and will utilise the most efficient structure that meets the requirements of the Regal Group in the prevailing circumstances at the time, it is anticipated that further investment to fund the Regal Group's required capital expenditure programme would take the form of shareholder loans.

It is intended that the injection of further capital will allow Energees Management and Regal to explore options to increase productivity which, in addition to growing productivity of Regal's existing wells, may also include, subject to appropriate opportunities arising at the relevant time which might benefit the Regal Group, potential acquisitions and/or joint usage of existing State controlled wells and, subsequently, the exploration and drilling of new wells.

Experienced management team

Energees Management believes that the experience of the Smart Holding Group as a whole, and its established track record in operating in Ukraine's natural resources sector, as well as management with oil & gas expertise, will facilitate the efficient development of the Regal business. Energees Management also believes that Regal would form an important platform for further growth, potentially leading to the creation of a market leader amongst Ukraine-focused independent E&P players.

Operational and legal support

Energees Management intends to explore with the Regal Directors ways in which the operational expenses of Regal can be reduced and revenue increased. As part of the Smart Holding Group, Regal will also have access to its management team, whom Energees Management believes are well placed to address the legal issues, particularly in connection with the licence disputes, facing the Company. Being one of the largest diversified groups of companies in Ukraine, Smart Holding Group has extensive experience of operating companies in Ukraine which will be valuable in assisting Regal to address and seek to mitigate any existing and potential legal risks that may face the Regal business.

Proposed Board appointments and relationship agreement

Following completion of the Partial Offer, a number of changes to the Board of Regal are contemplated. It is intended that Alexey Tymofeyev, currently First Deputy CEO of JSC Smart Holding UA, will become CEO of Regal. Prior to joining the Smart Holding Group, Alexey held positions at NJSC Naftogaz of Ukraine, the Ukrainian state oil and gas company, Geo-Alliance and SC Ukrgazvydobuvannya, a subsidiary of NJSC Naftogaz. It is also intended that Alexey Pertin, currently a director of Energees Investments and Energees Management and CEO of JSC Smart Holding UA, and Denis Rudev, a Director of Energees Management and CFO of JSC Smart Holding UA, will also be appointed to the Board as executive directors of Regal. Robert Wilde and Hendrikus Verkuil will continue in their respective roles as Finance Director and Chief Operating Officer. Keith Henry will continue in his role as Chairman of Regal, on a non-executive basis and the current, existing non-executive directors of Regal, Adrian Coates and Alastair Graham, will remain in place.

Energees Management has confirmed that Regal will remain an independently managed public company and that it has no intention to cancel Regal's admission to trading on AIM in the next 12 months. Energees Management has agreed that it will enter into a relationship agreement to regulate the relationship between the Smart Holding Group and Regal. The principal purpose of the relationship agreement is to provide that the relationship between members of the Smart Holding Group and the Regal Group will be conducted independently and on an arm's length basis. The agreement will address, inter alia, the composition of the Regal Board (to ensure a fair representation of non-executive directors and the entitlement of Energees Management to appoint three directors to the Board (one of which will be the CEO)) and will preclude any of the directors of Regal, who are interested in the Smart Holding Group, from voting at meetings of the Board on matters in which the Smart Holding Group is interested.

5 Recommendation

The Regal Directors, who have been so advised by BofA Merrill Lynch, consider the terms of the Increased Partial Offer to be fair and reasonable. In providing its advice, BofA Merrill Lynch has taken into account the commercial assessments of the Regal Directors.

Accordingly, the Regal Directors intend unanimously to recommend that Shareholders accept and approve the Increased Partial Offer.

The Regal Directors who hold Regal Shares entered into irrevocable undertakings to accept the Original Offer in respect of their own beneficial holdings (and, where applicable, those of their spouses) totalling, in aggregate, 577,245 Regal Shares, representing approximately 0.18 per cent. of Regal's existing issued share capital (the Director Irrevocable Undertakings) and have tendered acceptances in respect of such Regal Shares. These acceptances will be treated as acceptances of the Increased Partial Offer in respect of 577,245 Regal Shares. The Director Irrevocable Undertakings remain in full force and effect and binding even in the event of a higher competing offer for Regal and the Regal Directors can not withdraw such acceptances. In addition, the Regal Directors will tender Approval Forms in respect of the Regal Shares the subject of the Director Irrevocable Undertakings. Further details on the Director Irrevocable Undertakings (together with the further irrevocable undertakings referred to in paragraph 7 below) are contained in Appendix 2 to this Announcement.

6 Background to and reasons for the recommendation

In September 2010, following a set of disappointing drilling results and against the backdrop of Regal licences in Ukraine being challenged, Regal initiated a strategic review. The review concluded that the development of the Company's Ukrainian asset required further technical studies to evaluate the reservoir potential and any impact on the Company's reserves estimate, as well as to determine how much investment capital would be required to fund future development. As a result of the suspension of production in Ukraine, the disappointing results from drilling and the requirement for further technical studies, Regal considers it likely that its current published reserves would be revised downwards, both in terms of quantum and category, in the event that the proposed technical studies and the subsequent trials of alternative completion technologies, such as hydraulic fracturing, were to prove unsuccessful in improving well productivity.

As part of the strategic review, the Company entered into negotiations with several parties, including Energees Management and Heamoor and Geo-Alliance, with respect to potential corporate options. This resulted in the announcement of the Original Offer by Regal and Energees Investments on 10 December 2010.

The Board of Regal recommended the Original Offer from Energees Management of 24 pence per Regal Share in cash, having concluded that the Original Offer represented better value and certainty for Regal Shareholders than the Company remaining an independent quoted entity at that time. In recommending the Original Offer, the Board of Regal took the following facts into consideration:

    - the technical difficulties associated with bringing the wells to
    sustainable commercial production rates;

    - the uncertainty in the outcomes of further reservoir appraisal and the
    potential impact, if any, on the reserves estimate;

    - loss of operational revenue as a result of the suspension order and
    uncertainty as to when production may be allowed to resume;

    - additional capital requirements for further appraisal and field
    development; and

    - the ongoing legal and political risks surrounding the Ukrainian
    operations.

Shortly after the Original Offer was announced, Heamoor announced, pursuant to Rule 2.4 of the Takeover Code, its interest in making an offer to acquire the Company or, agreeing a potential business combination with the Company. On 18 January 2011, Regal announced the details of a non-binding proposal from Heamoor and Geo-Alliance (the Geo Proposal), which involved, inter alia, a proposed reverse take-over of Geo-Alliance by Regal, with an option for Regal Shareholders to sell their shares to Heamoor at a price of 25 pence per Regal Share for three months following completion of the reverse take-over. The proposed reverse take-over of Geo-Alliance envisaged that Regal would acquire Geo-Alliance, in exchange for the issue of new Regal Shares to the shareholders of Geo-Alliance, representing not more than 70 per cent. of Regal's enlarged share capital post the issue of new Regal Shares. As such transaction would constitute a reverse take-over under the AIM Rules, the announcement of the proposed transaction with Geo-Alliance resulted in the suspension of trading in Regal Shares on AIM.

To date, with the aim of securing for Regal Shareholders a superior offer to the Original Offer of 24 pence per share, the Regal Board and Regal's advisers have been working intensively with Heamoor and Geo-Alliance towards reaching a firm, binding announcement of a transaction on the terms outlined in the announcement of 18 January 2011. Given the complex nature of the Geo Proposal, which involves extensive due diligence and documentary requirements for a reverse take-over, the required re-admission of the enlarged group to trading on AIM, as well as the timetable constraints imposed by the Takeover Code, Regal negotiated and agreed with Geo-Alliance and its shareholders a cost coverage agreement whereby the fees, costs and expenses properly incurred by the Regal Group solely in connection with the consideration, negotiation and documenting of the Geo Proposal, would be reimbursed, subject to a maximum amount.

The Increased Partial Offer has been announced today by Energees Management on the condition that Regal terminate its discussions with Heamoor and Geo-Alliance towards reaching a binding transaction on the terms previously announced.

Based on work completed to date in connection with the Geo Proposal by Regal and its advisers and the Board's assessment of the certainty of being able to finalise all required workstreams and to announce a binding transaction with Heamoor and Geo-Alliance by 10 February 2011, the Board of Regal has concluded that the Increased Partial Offer represents a superior proposition with respect to certainty of value by comparison to the Geo Proposal.

The Board of Regal has concluded that the Increased Partial Offer is the best and only firm option currently available to Regal Shareholders. The Board's recommendation of the Increased Partial Offer has taken the following into consideration:

    - the revised, increased, cash consideration per share offered
    by Energees Management;
    - Energees Management's receipt of approval from the Anti-Monopoly
    Commission of Ukraine;
    - the ability for Regal Shareholders to maintain a meaningful stake
    in Regal under the new majority ownership of Energees Management;
    - greater certainty of value for Regal Shareholders than: a) the
    proposed transaction with Heamoor and Geo-Alliance; or b) the Company
    remaining an independent quoted entity without the majority ownership of
    Energees Management;
    - Smart Group's experience and successful record in Ukraine, as
    well as its commitment to provide the operational, legal, management and
    financial support to Regal;
    - there is no guarantee that any offer or proposal from Heamoor
    and/or Geo-Alliance will ultimately be put to Regal Shareholders within
    the timetable requirements of the Takeover Code; and
    - the partial offer structure enables Regal Shareholders, depending
    on their objectives, to elect to receive more or less cash as
    consideration (subject to scaling down on the basis set out in paragraph
    2 of this Announcement) and allows those seeking ongoing equity exposure
    to Regal to select equity and maximise their ongoing stake in Regal.

7 Irrevocable undertakings

In addition to the irrevocable undertakings given by the Regal Directors (as referred to in paragraph 5 above) Energees Management has received: (i) irrevocable undertakings from each of Renaissance Securities (Cyprus) Limited and Hadron Capital LLP to accept and approve the Increased Partial Offer in respect of a total of 26,447,366 Regal Shares (representing approximately 8.31 per cent. of the existing issued ordinary share capital of Regal); and (ii) as part of the irrevocable undertaking from Hadron Capital LLP, an undertaking to use its reasonable endeavours to procure (so far as it is able) that a further 15,484,800 Regal Shares (in respect of which it holds its interest through long derivative contracts and representing approximately 4.86 per cent. of the existing issued ordinary share capital of Regal) will be assented to, and approve, the Increased Partial Offer (the New Irrevocable Undertakings). The New Irrevocable Undertakings remain binding including in the event of a competing offer being made for Regal and will only lapse if the Increased Partial Offer lapses or is withdrawn.

Energees Management has therefore received (in aggregate and taking into account the Director Irrevocable Undertakings referred to in paragraph 5 above) irrevocable undertakings to accept and approve (or, in the case of the New Irrevocable Undertaking given by Hadron Capital LLP to use its reasonable endeavours to procure (so far as it is able) that the 15,484,800 Regal Shares represented by long derivative contracts are assented to and approve) the Increased Partial Offer in respect of 42,509,411 Regal Shares, representing approximately 13.35 per cent. of Regal's existing issued ordinary share capital.

Further details of the Director Irrevocable Undertakings and the New Irrevocable Undertakings are contained in Appendix 2 to this Announcement.

8 Financing of the Increased Partial Offer and cash confirmation

Full acceptance of the Increased Partial Offer will result in the payment by Energees Management of approximately GBP85.3 million in cash.

The aggregate cash consideration payable by Energees Management will be provided from existing cash resources.

UBS Investment Bank, financial adviser to Energees Investments and Energees Management, is satisfied that resources are available to Energees Management sufficient to satisfy full acceptance of the Increased Partial Offer.

9 Regal LTIP

The Increased Partial Offer will extend to any Regal Shares issued or unconditionally allotted or issued fully paid (or credited as fully paid) on or after the date the Increased Partial Offer is made and before the Record Date (or such earlier date as Energees Management may, subject to the Takeover Code, determine), including those Regal Shares allotted or issued as a result of the exercise or vesting of options or awards under the Regal LTIP. Appropriate proposals were made by Energees Management to Regal LTIP option holders on 23 December 2010. Forms of instruction that have already been returned in connection with such proposals will remain valid with regard to proposals to be made in connection with the Increased Partial Offer (subject to scaling down on the basis set out in paragraph 2 of this Announcement and subject to any written instructions to the contrary received from the relevant Regal LTIP option holders). Further details in connection with proposals to be made to Regal LTIP holders will be sent as soon as practicable.

10 Inducement Fee

Energees Management and Regal have entered into an inducement fee agreement dated 6 February 2011, under the terms of which Regal has agreed to pay Energees Management an inducement fee of GBP852,896 (equal to one per cent. of the value of the Regal Shares the subject of the Increased Partial Offer based on the price of 38 pence per Regal Share under the Increased Partial Offer). The inducement fee would be payable if, prior to the Increased Partial Offer lapsing or being withdrawn, one or more Alternative Offers are announced and any of such Alternative Offers subsequently become effective, become or are declared unconditional in all respects or are otherwise completed. An Alternative Offer would include implementation of the proposals (announced on 18 January 2011 by Regal) made by Heamoor and Geo-Alliance, or any revisions thereto.

11 Interests in Regal

Neither Energees Management nor any of the directors of Energees Management, nor, so far as the directors of Energees Management are aware, any person acting in concert with Energees Management for the purposes of the Increased Partial Offer, has any interest in, right to subscribe for, or has borrowed or lent any Regal Shares or securities convertible or exchangeable into Regal Shares (Regal Securities), nor does any such person have any short position (whether conditional or absolute and whether in the money or otherwise) including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery or any arrangement in relation to Regal Securities.

For these purposes, "arrangement" includes any indemnity or option arrangement or any agreement or understanding, formal or informal, of whatever nature, relating to Regal Securities which may be an inducement to deal or refrain from dealing in such securities.

14 General

Save as set out in this Announcement, the Increased Partial Offer Document, the Approval Form and the New Form of Acceptance, the Increased Partial Offer will be made on the same terms and subject to the same conditions as set out in the Original Offer Document. The Increased Partial Offer Document setting out the full terms of the Increased Partial Offer will be sent to Regal Shareholders (other than persons in a Restricted Jurisdiction) today together with the Approval Form and New Form of Acceptance. In deciding whether or not to accept the Increased Partial Offer, Regal Shareholders should rely solely on the information contained in, and follow the procedures set out in, the Original Offer Document, the Increased Partial Offer Document, the Approval Form, the Original Form of Acceptance and the New Form of Acceptance.

As stated above, under Rule 36.5 of the Takeover Code, approval of the Increased Partial Offer by Regal Shareholders is required and the Increased Partial Offer will be conditional upon such approval being obtained. For this condition to be satisfied, Regal Shareholders who are independent of Energees Management and persons acting in concert with Energees Management and represent more than 50 per cent. of the voting rights in Regal must give their approval to the Increased Partial Offer. If such approval is not obtained, the Increased Partial Offer will lapse.

Action to be taken by Regal Shareholders who have not accepted the Original Offer

    Regal Shareholders who want to accept the Increased Partial Offer should:

    - once they have received the New Form of Acceptance and if they hold
    their Regal Shares, or any of them, in certificated form (that is, not in
    CREST), complete, sign and return the New Form of Acceptance (together
    with their share certificate(s) and other document(s) of title) in
    accordance with the instructions set out in the Increased Partial Offer
    Document as soon as possible and, in any event, so as to be received by
    the Registrars not later than 1.00p.m. on 20 February 2011; or

    - once they have received the Increased Partial Offer Document, and if
    they hold their Regal Shares, or any of them, in uncertificated form
    (that is, in CREST), follow the procedure for electronic acceptance
    through CREST in accordance with the instructions set out in the
    Increased Partial Offer Document so that the relevant TTE Instruction
    settles as soon as possible and, in any event, not later than 1.00 p.m.
    on 20 February 2011. In this context, Regal Shareholders should note
    that 20 February 2011 is a Sunday, so to be effective the TTE Instruction
    must in fact settle in CREST not later than Friday 18 February 2011.
    Shareholders who hold their Regal Shares as a CREST sponsored member
    should refer to their CREST sponsor, as only their CREST sponsor will be
    able to send the necessary TTE Instruction(s) to CREST.

If Regal Shareholders approve of the Increased Partial Offer (whether or not they wish to accept the Increased Partial Offer, and whether they hold their Regal Shares in certificated form or uncertificated form) they should complete and return the Approval Form (once received by them) in accordance with the procedures set out in the Increased Partial Offer Document as soon as possible and, in any event, so as to be received by the Registrars not later than 1.00 p.m. on 20 February 2011. If approval of the Increased Partial Offer is not given by Regal Shareholders who are independent of Energees Management and persons acting in concert with Energees Management and represent more than 50 per cent. of the voting rights in Regal the Increased Partial Offer will lapse.

Action to be taken by Regal Shareholders who have accepted the Original Offer

Acceptances of the Original Offer which have not been validly withdrawn are deemed to be acceptances of the Increased Partial Offer in respect of the same number of Regal Shares (subject to scaling down on the basis set out above to the extent this exceeds the Relevant Percentage of the Shareholder's holding (or deemed holding) at the Record Date).

Regal Shareholders who have accepted the Original Offer need not complete a New Form of Acceptance (in the case of Regal Shares held in certificated form) or submit a further electronic instruction (in the case of Regal Shares held in uncertificated form) unless they wish to reduce the number of Regal Shares the subject of their acceptance, however if they approve of the Increased Partial Offer (whether they hold their Regal Shares in certificated form or uncertificated form) they should complete and return the Approval Form (once received by them) in accordance with the procedures set out in the Increased Partial Offer Document as soon as possible and, in any event, so as to be received by the Registrars not later than 1.00 p.m. on 20 February 2011. If approval of the Partial Offer is not given by Regal Shareholders as outlined above, the Increased Partial Offer will lapse.

Regal Shareholders who have accepted the Original Offer and wish to reduce the number of Regal Shares the subject of their acceptance should:

    - once they have received the New Form of Acceptance, in respect of Regal
    Shares held in certificated form (that is, not in CREST), lodge with the
    Registrars, in accordance with the instructions set out in the Increased
    Partial Offer Document and prior to 1.00 p.m. on 20 February 2011, a
    validly completed New Form of Acceptance together with written
    confirmation that this replaces the Original Form of Acceptance
    previously sent to the Registrars; or

    - once they have received the Increased Partial Offer Document, in
    respect of Regal Shares held in uncertificated form (that is, in CREST)
    send, in accordance with the instructions set out in the Increased
    Partial Offer Document, an ESA Instruction to settle in CREST in relation
    to each electronic acceptance to be withdrawn. Shareholders should then
    send, in accordance with the instructions set out in the Increased
    Partial Offer Document, a TTE Instruction to Euroclear in respect of
    the reduced number of Regal Shares which such Shareholder wishes to be
    the subject of their acceptance. The aforementioned ESA Instruction and
    TTE Instruction should both be sent as soon as possible and, in any
    event, so as to settle not later than 1.00 p.m. on 20 February 2011. In
    this context, Regal Shareholders should note that 20 February 2011 is a
    Sunday, so to be effective the ESA Instruction and the TTE Instruction
    must in fact settle in CREST not later than Friday 18 February 2011.
    Shareholders who hold their Regal Shares as a CREST sponsored member
    should refer to their CREST sponsor, as only their CREST sponsor will be
    able to send the necessary ESA Instruction(s) to CREST; and

    - once they have received the Approval Form, whether they hold their
    Regal Shares in certificated form or uncertificated form, complete and
    lodge with the Registrars, in accordance with the instructions set out
    in the Increased Partial Offer Document and prior to 1.00 p.m. on 20
    February 2011, a validly completed Approval Form.

Sources and bases of information

In this Announcement:

1 The value of the Increased Partial Offer based on the offer price of 38 pence per Regal Share is calculated on the basis of the fully diluted number of Regal Shares in issue referred to in paragraph 2 below.

2 As at the close of business on 4 February 2011 (being the last business day prior to the date of this Announcement), Regal had in issue 318,366,876 Regal Shares. The ISIN Number for Regal Shares is GB0031775819.

3 The fully diluted share capital of Regal as at 4 February 2011 (being 320,637,836 Regal Shares) is calculated on the basis of:

    - the number of Regal Shares referred to in paragraph 2 above; and

    - any further Regal Shares which may be issued on or after the
    Announcement Date on the exercise or vesting of options or awards under
    the Regal LTIP, amounting to 2,270,960 Regal Shares as at 4 February
    2011.

Warrants to subscribe for 846,600 Regal Shares at a subscription price of GBP1.50 per share are also outstanding, but have not been taken into account in determining the fully diluted share capital as they are "out of the money".

4 Unless otherwise stated, all prices and closing prices for Regal Shares are closing middle market quotations derived from the Daily Official List.

5 The premium calculations to the price per Regal Share have been calculated by reference to:

    - a price of 12.5 pence per Regal Share, being the closing price on 24
    November 2010, the last business day prior to the commencement of the
    Offer Period; and

    - the average closing price per Regal Share of 15.4 pence over the one
    month period ended 24 November 2010 is derived from data provided by
    Datastream.

6 The reference to the price per Regal Share under the Increased Partial Offer being 13 pence more than the proposed purchasing commitment or proposed pre-conditional cash offer by Heamoor and Geo-Alliance (and other references to such proposals by them) are derived from the terms of such proposals as set out in the announcement released by Regal with the consent of Heamoor and Geo-Alliance on 18 January 2011.

Appendix 2

Details of irrevocable undertakings

Part A - New Irrevocable Undertakings

    Energees Management has received the following irrevocable undertakings
from each of Renaissance Securities (Cyprus) Limited and Hadron Capital LLP
to accept and approve the Increased Partial Offer in respect of a total of
41,932,166[1] Regal Shares, representing approximately 13.17 per cent. of the
existing issued ordinary share capital of Regal. These irrevocable
undertakings remain binding including in the event of a competing offer being
made for Regal and will only lapse if the Increased Partial Offer lapses or
is withdrawn.

[1] Of the 17,484,800 Regal Shares the subject of the irrevocable undertaking given by Hadron Capital LLP, 15,484,800 are shares in respect of which Hadron Capital LLP holds its interest through long derivative contracts. Whilst Hadron Capital LLP has undertaken to use its reasonable endeavours to procure (so far as it is able) that the underlying Regal Shares represented by such long derivative contracts which are the subject of the irrevocable undertaking given by it will be assented to, and approve, the Increased Partial Offer, it should be noted that Hadron Capital LLP has no contractual rights to call for the delivery of any Regal Shares underlying the relevant long derivative contracts or to direct how the votes attaching to such shares are cast. There can therefore be no guarantee that all (or any) of the underlying Regal Shares represented by the long derivative contracts and the subject of the irrevocable given by Hadron Capital LLP will in fact be assented to or approve the Increased Partial Offer.

Part B - Director Irrevocable Undertakings

The Regal Directors entered into irrevocable undertakings to accept the Original Offer in respect of their own beneficial holdings (and, where applicable, those of their spouses) totalling, in aggregate, 577,245 Regal Shares, representing approximately 0.18 per cent. of Regal's existing issued share capital and have tendered acceptances in respect of such Regal Shares. These acceptances will be treated as acceptances of the Increased Partial Offer in respect of 577,245 Regal Shares. The irrevocable undertakings remain in full force and effect and binding even in the event of a higher competing offer for Regal and the Regal Directors can not withdraw such acceptances. In addition, the Regal Directors will tender Approval Forms in respect of the Regal Shares the subject of their irrevocable undertakings.
