RECOMMENDED CASH, SHARE AND CONTINGENT CONSIDERATION OFFER

ROCKHOPPER EXPLORATION PLC

for

MEDITERRANEAN OIL & GAS PLC

(to be effected by means of a scheme of arrangement under

Part 26 of the Companies Act 2006)

-- The boards of Rockhopper Exploration plc ("Rockhopper") and of Mediterranean Oil & Gas plc ("MOG") are pleased to announce that they have reached agreement on the terms of a recommended acquisition under which Rockhopper will acquire the entire issued and to be issued ordinary share capital of MOG (the "Acquisition"). The Acquisition is to be effected by means of a Court sanctioned scheme of arrangement under Part 26 of the Companies Act 2006.

-- Under the terms of the Acquisition, shareholders of MOG ("MOG Shareholders") will receive 6.5 pence per share ("MOG Share") comprising 4.875 pence in cash and 0.0172 shares of Rockhopper per MOG share (together the "Initial Consideration Offer").

-- In addition, under the terms of the Acquisition, MOG Shareholders will receive a contingent entitlement up to a maximum amount of 3.550 pence in cash for each MOG Share (the "Contingent Consideration Offer") assuming MOG's fully diluted ordinary share capital is 451,192,831.

   --            The Initial Consideration Offer:

-- values the entire issued and to be issued share capital of MOG at approximately GBP29.3 million;

-- represents a 15.6 per cent premium to MOG's closing share price of 5.625 pence on 22 May 2014 (being the last Business Day prior to the date of this announcement); and

-- represents a 31.1 per cent premium to MOG's average volume weighted share price of 4.957 pence for the three months ended 22 May 2014 (being the last Business Day prior to the date of this announcement).

-- The shares of Rockhopper forming part of the Initial Consideration Offer and to be issued pursuant to the Acquisition (the "Rockhopper Consideration Shares") are expected to represent approximately 2.65 per cent of the issued share capital of Rockhopper as enlarged by the Acquisition. The Rockhopper Consideration Shares will rank equally in all respects with the existing Rockhopper Shares and will be entitled to all dividends and/or other distributions declared or paid by Rockhopper in respect of Rockhopper Shares by reference to a record date falling after the Effective Date.

-- The availability of the Contingent Consideration Offer, and the amount of cash which may ultimately be payable in connection therewith (the "Contingent Consideration"), will be determined by the success of an exploration well targeting the Hagar Qim prospect in Offshore Malta Area 4, Block 7 (the "HQ Prospect"). The Contingent Consideration Offer is intended to afford MOG Shareholders an opportunity to benefit from the potential success of the HQ Prospect.

The Contingent Consideration Offer is a contractual, non-transferable, unsecured, interest-free obligation of Rockhopper to make (subject to certain conditions) an additional one-off cash payment of between GBP11.9 million and GBP16.0 million in total (the "Total Contingent Consideration Amount"). The Contingent Consideration will only be payable if the 2C Contingent Resources of Liquid Hydrocarbons estimated to be potentially recoverable from the HQ Prospect equal or exceed 80 mmbbl in total, which is a level that the Rockhopper Directors consider to be commercially viable.

The Total Contingent Consideration Amount shall be calculated on the basis of 25 per cent (being the percentage interest which MOG holds in the HQ Prospect) multiplied by GBP0.59 multiplied by the 2C Contingent Resources of Liquid Hydrocarbons estimated to be potentially recoverable from the HQ Prospect. The Total Contingent Consideration Amount payable will be subject to a hurdle of 20 mmbbl 2C Contingent Resources of Liquid Hydrocarbons estimated to be potentially recoverable from the HQ Prospect (on a Net Basis) and will be capped at GBP16.0 million. The Contingent Consideration, if payable, will be equivalent to Rockhopper paying approximately US$ 1 per barrel of 2C Contingent Resources of Liquid Hydrocarbons

If any Contingent Consideration is payable, Relevant Shareholders will receive, for every MOG Share held, an amount calculated by dividing the Total Contingent Consideration Amount by the aggregate number of MOG Shares in issue at the Reduction Record Time plus the number of MOG Shares issued after that date pursuant to the exercise of options and share awards under the MOG Share Plans. .

The Contingent Consideration Offer is conditional and subject to the cap summarised above and therefore there is no certainty that all or any Contingent Consideration will become payable in connection with the Acquisition.

-- The deferred shares issued by MOG as part of a reorganisation of its share capital in 2011 will be unaffected by and will not form part of the Acquisition and the Scheme.

-- The cash consideration payable under the terms of the Acquisition, including any payments due under the Contingent Consideration Offer, will be financed from existing cash resources of Rockhopper.

-- The MOG Directors, who have been so advised by RBC Europe Limited ("RBC"), as the independent financial adviser for the purposes of Rule 3 of the Takeover Code, consider the terms of the Acquisition to be fair and reasonable. In providing its advice to the MOG Directors, RBC has taken into account the commercial assessments of the MOG Directors.

-- Accordingly, the MOG Directors intend to recommend unanimously that MOG Shareholders vote in favour of the resolutions to be proposed at the Court Meeting and the General Meeting which are to be convened to approve and implement the Acquisition.

-- The MOG Directors have irrevocably undertaken to approve the necessary resolutions in respect of their entire beneficial holdings in MOG, which, in aggregate, amount to 2,588,171 MOG Shares, representing approximately 0.60 per cent of the existing issued ordinary share capital of MOG. These irrevocable undertakings will cease to be binding only if the Scheme lapses or is withdrawn and remain binding if a higher competing offer for MOG is made.

-- In addition, Rockhopper has received irrevocable undertakings to vote in favour of the Scheme at the Court Meeting and in favour of the resolution at the General Meeting from certain MOG Shareholders in respect of 135,297,780 MOG Shares representing, in aggregate, approximately 31.36 per cent of the existing issued ordinary share capital of MOG. These irrevocable undertakings will cease to be binding only if the Scheme lapses or is withdrawn or if a competing offer for MOG is made which represents the increase to the Initial Consideration and the Contingent Consideration set out in Appendix 3 of this announcement.

-- Therefore, as at the date of this announcement, Rockhopper has received irrevocable undertakings to vote in favour of the Scheme at the Court Meeting and in favour of the resolution at the General Meeting in respect of a total of 137,885,951 MOG Shares, representing, in aggregate, approximately 31.96 per cent of MOG's existing issued ordinary share capital.

-- Rockhopper is an AIM-quoted exploration and production company with its principal asset being 5,800km(2) of prospective oil and gas acreage in the North Falkland Basin, which contains up to 450 mmbbl of 2C Contingent Resources if a gas cap does not exist on the western flank of the Sea Lion field. Rockhopper has a robust balance sheet, with current cash of approximately US$ 250 million (GBP147 million).

-- MOG is an AIM-quoted exploration and production company with operations in Italy, Malta and France. MOG produces natural gas onshore and offshore in Italy and has a balanced portfolio of exploration, appraisal and development opportunities with reserves and contingent resources of 33 mmboe and total unrisked prospective resources of over 1,200 mmboe. Net production from the Guendalina field, MOG's principal production asset, was 35,650 scm per day as of 13 May 2014. Development activities are focused on MOG's 100 per cent operated interest in the offshore Italian Ombrina Mare discovery, which has 2C Contingent Resources of 26.5 mmboe. MOG is also undertaking high-impact exploration offshore Malta and will drill the HQ Prospect in 2014 targeting net mean unrisked resources of 27 mmboe. MOG also holds additional development and exploration opportunities in Italy, Malta and France.

-- In order to become effective, the Scheme requires the sanction of the Court and must be approved by the requisite majority of MOG Shareholders. The Scheme is also conditional on, among other things, the Government of the Republic of Malta. either confirming that consent is not required for the indirect change of control of Melita Exploration Company Limited (a subsidiary of MOG) or, if it is required, giving such consent.

-- It is currently expected that the Scheme Document, containing further information about the Acquisition and notices of the Court Meeting and the General Meeting, together with the Forms of Proxy, will be posted not later than 20 June 2014 and that, subject to the satisfaction or, where relevant, waiver of all relevant Conditions, the Scheme is expected to become effective on or around 5 August 2014.

   --            Commenting on the Acquisition, Pierre Jungels, Chairman of Rockhopper said:

"This transaction represents an important milestone for the company as we add production to our portfolio and broaden our exploration and development opportunity set, by establishing ourselves in an area our team understands well. While the acquisition cost and capital exposure are modest in relation to our balance sheet, the upside potential is significant and we believe that the new acreage will create an attractive entry platform to one of the most exciting regions in the industry at this time."

   --            Commenting on the Acquisition, Keith Henry of MOG said:

"This is a good transaction for our shareholders, offering them the combination of both cash and shares in Rockhopper today, while also providing the opportunity to benefit from the potential upside of our Malta well. Sadly, a series of setbacks over the past year at the Guendalina Field, MOG's principal producing asset, and the continuing regulatory delays to Ombrina Mare, our key development project, have prevented us from implementing our strategy of growing our portfolio in the Mediterranean region. In the current market conditions, the MOG board strongly believes that this can only be achieved by a significantly more capitalised company. In addition to the cash element, Rockhopper's offer represents an opportunity for MOG shareholders to receive shares in Rockhopper, while still retaining a contingent interest in the high risk exploration well offshore Malta that will spud in the next few days."

This announcement contains certain forward-looking statements with respect to the financial condition, results of operations and business of the MOG Group and certain plans and objectives of the boards of directors of MOG and Rockhopper. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as "anticipate", "target", "expect", "estimate", "intend", "plan", "goal", "believe", "will", "may", "should", "would", "could" or other words of similar meaning. These statements are based on assumptions and assessments made by the boards of directors of MOG and Rockhopper in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe appropriate. By their nature, forward-looking statements involve risk and uncertainty, and the factors described in the context of such forward-looking statements in this announcement could cause actual results and developments to differ materially from those expressed in or implied by such forward-looking statements. Should one or more of these risks or uncertainties materialise, or should underlying assumptions prove incorrect, actual results may vary materially from those described in this announcement. MOG and Rockhopper assume no obligation to update or correct the information contained in this announcement, whether as a result of new information, future events or otherwise, except to the extent legally required.

The statements contained in this announcement are made as at the date of this announcement, unless some other time is specified in relation to them, and publication of this announcement shall not give rise to any implication that there has been no change in the facts set out in this announcement since such date. Nothing contained in this announcement shall be deemed to be a forecast, projection or estimate of the future financial performance of MOG and Rockhopper except where expressly stated.

No profit forecast

No statement in this announcement is intended as a profit forecast or a profit estimate, and no statement in this announcement should be interpreted to mean that the future earnings per MOG Share for current or future financial years will necessarily match or exceed the historical or published earnings per MOG Share.

BOE presentation

References herein to "boe" mean barrels of oil equivalent derived by converting gas to oil in the ratio of between 5,500 to 6,000 cubic feet (scf) of gas (dependent on the richness of the gas) to one barrel (bbl) of oil. Boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6,000 scf: 1 bbl is based on an energy conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

RECOMMENDED CASH, SHARE AND CONTINGENT CONSIDERATION OFFER

ROCKHOPPER EXPLORATION PLC

for

MEDITERRANEAN OIL & GAS PLC

(to be effected by means of a scheme of arrangement under

Part 26 of the Companies Act 2006)

   1.          Introduction

The boards of MOG and Rockhopper are pleased to announce that they have reached agreement on the terms of a recommended acquisition under which Rockhopper will acquire the entire issued and to be issued ordinary share capital of MOG.

   2.          Summary of terms

2.1 It is intended that the Acquisition will be effected by way of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act. The Scheme requires approval by MOG Shareholders at the Court Meeting and the General Meeting which are to be convened in connection with the Scheme. Further details of the Court-sanctioned scheme of arrangement and the requisite level of MOG Shareholder approvals are contained in paragraph 13 below.

2.2 Under the terms of the Acquisition, Relevant Shareholders will receive 6.5 pence for each MOG Share held, comprising 4.875 pence in cash and 0.0172 Rockhopper Consideration Shares (the "Initial Consideration Offer").

2.3 In addition, under the terms of the Acquisition, MOG Shareholders will receive a contingent entitlement up to a maximum amount of 3.550 pence in cash for each MOG Share held (the "Contingent Consideration Offer"), assuming MOG's fully diluted ordinary share capital is 451,192,831.

   2.4        The Initial Consideration Offer:

-- values the entire issued and to be issued share capital of MOG at approximately GBP29.3 million;

-- represents a 15.6 per cent premium to MOG's closing share price of 5.625 pence on 22 May 2014 (being the last Business Day prior to the date of this announcement); and

2.5 The Rockhopper Consideration Shares to be issued pursuant to the Acquisition are expected to represent approximately 2.65 per cent of the issued share capital of Rockhopper as enlarged by the Acquisition. The Rockhopper Consideration Shares will rank equally in all respects with the existing Rockhopper Shares and will be entitled to all dividends and/or other distributions declared or paid by Rockhopper in respect of Rockhopper Shares by reference to a record date falling after the Effective Date. Fractions of Rockhopper Consideration Shares will not be allotted to Relevant Shareholders pursuant to the Acquisition. However, the entitlements of Relevant Shareholders will be rounded up or down (with 0.5 of a Rockhopper Consideration Share being rounded up) to the nearest whole number of Rockhopper Consideration Shares.

The availability of the Contingent Consideration Offer, and the amount of cash which may ultimately be payable in connection therewith (the "Contingent Consideration"), will be determined by the success of an exploration well targeting the Hagar Qim prospect in Offshore Malta Area 4, Block 7 (the "HQ Prospect"). The Contingent Consideration Offer is intended to afford MOG Shareholders an opportunity to benefit from the potential success of the HQ Prospect.

2.6 The Deferred Shares will not form part of, and will be unaffected by, the Acquisition or the Scheme. For further details, please see paragraph 8 below.

   3.          The Contingent Consideration Offer 
   3.1        Summary of the Contingent Consideration Offer

(a) The Contingent Consideration Offer is designed to enable MOG Shareholders to benefit from the potential success of the HQ Exploration Well, subject to the Contingent Consideration Condition being met.

(b) The Contingent Consideration Offer is conditional and therefore there is no certainty that all or any Contingent Consideration will become payable in connection with the Acquisition.

(c) MOG, together with its partner Genel, intends to drill the HQ Exploration Well, which is expected to be Spudded on or around 25 May 2014. As the results of the HQ Exploration Well are not expected to be known before mid to late July 2014, the Contingent Consideration Offer is being made available to Relevant Shareholders.

(d) The Contingent Consideration Offer is a contractual, non-transferable, unsecured, interest-free obligation of Rockhopper to make (subject to the Contingent Consideration Condition) an additional one-off cash payment of between GBP11.9 million and GBP16.0 million in total (the "Total Contingent Consideration Amount") to all Relevant Shareholders.

(e) The actual amount of the Contingent Consideration due to each Relevant Shareholder will be determined by (i) the economic viability of the HQ Prospect, based on the amount of the Agreed Resources associated with the HQ Exploration Well, calculated as set out in paragraphs 3.3 and 3.4 below and (ii) the number of Relevant Shares (assumed in this announcement to be 451,192,831 shares).

   3.2        The Contingent Consideration Condition

The Contingent Consideration will be payable to Relevant Shareholders only if:

(a) the HQ Exploration Well is Spudded before the Effective Date or 17 July 2014, whichever is the earlier; and

(b) the Agreed Resources are equal to or exceed 20 million barrels of Liquid Hydrocarbons (on a Net Basis); and

   (c)       MOG's interest in the HQ Prospect is 25 per cent at the Effective Date,

(together, being the "Contingent Consideration Condition").

The Contingent Consideration Offer will lapse if the Contingent Consideration Condition is not fulfilled. In such circumstances Relevant Shareholders will receive the Initial Consideration only; no Contingent Consideration will be payable to Relevant Shareholders.

   3.3        Determination of the Agreed Resources

(a) Rockhopper will make an RNS announcement within two Business Days of the HQ Exploration Well Completion Date, confirming the HQ Exploration Well Completion Date.

(b) As soon as reasonably practicable, and in any event no later than one month after the HQ Exploration Well Completion Date, Rockhopper shall instruct the Competent Person to produce the Competent Person's Report to determine the 2C Contingent Resources estimated to be potentially recoverable from the HQ Prospect (the "HQ Prospect 2C Contingent Resources").

(c) The Competent Person shall be instructed to submit the Competent Person's Report to Rockhopper within 90 days of the instruction by Rockhopper. The Competent Person's Report will be final as to the level of HQ Prospect 2C Contingent Resources, which shall then constitute the Agreed Resources, save as set out in sub-paragraphs (d) and (e) below. Rockhopper will make an RNS announcement within two Business Days of the Competent Person's Report being submitted to Rockhopper, and that announcement shall identify the HQ Prospect 2C Contingent Resources as determined by the Competent Person.

(d) If the Competent Person's Report determines that the HQ Prospect 2C Contingent Resources are of an amount:

(i) equal to or in excess of 20 million barrels of Liquid Hydrocarbons (on a Net Basis), the Contingent Consideration Condition will have been satisfied;

(ii) less than 18 million barrels of Liquid Hydrocarbons (on a Net Basis), the Contingent Consideration Condition will not have been satisfied and no Contingent Consideration will be payable;

(iii) equal to or in excess of 18 million barrels of Liquid Hydrocarbons (on a Net Basis) but less than 20 million barrels of Liquid Hydrocarbons (on a Net Basis), the provisions of sub-paragraph (e) below shall apply.

(e) If sub-paragraph (d)(iii) above applies, Rockhopper shall appoint the Second Competent Person to produce the Second Competent Person's Report to determine the HQ Prospect 2C Contingent Resources. The Second Competent Person shall be instructed to submit the Second Competent Person's Report to Rockhopper within 90 days of its appointment. In preparing its report, the Second Competent Person shall use the same data as used by the Competent Person in the preparation of the Competent Person's Report.

If the Second Competent Person's Report determines that the HQ Prospect 2C Contingent Resources are less than 20 million barrels of Liquid Hydrocarbons (on a Net Basis), such amount of 2C Contingent Resources will constitute the Agreed Resources and accordingly the Contingent Consideration Condition will not have been met and no Contingent Consideration will be payable.

If the Second Competent Person's Report determines that the HQ Prospect 2C Contingent Resources are more than 20 million barrels of Liquid Hydrocarbons (on a Net Basis), the Agreed Resources shall be determined by Rockhopper by calculating the average mean of (i) the HQ Prospect 2C Contingent Resources determined by the Competent Person and (ii) the HQ Prospect 2C Contingent Resources determined by the Second Competent Person (the "Average Resources"). The Contingent Consideration shall only be payable if the Average Resources equals or exceeds 20 million barrels of Liquid Hydrocarbons (on a Net Basis).

Rockhopper will make an RNS announcement within two Business Days of the Second Competent Person's Report being submitted to Rockhopper, which shall identify (i) the HQ Prospect 2C Contingent Resources as determined by the Second Competent Person and (ii) the Agreed Resources.

Rockhopper shall seek to obtain all relevant information reasonably required by the Competent Person (and, if applicable, the Second Competent Person) from the operator of the HQ Exploration Well in order for the Competent Person (and, if applicable, the Second Competent Person), to complete the Competent Person's Report (and, if applicable, the Second Competent Person's Report). Rockhopper shall provide, or procure the provision of, such information as is provided to it by the operator of the HQ Exploration Well to the Competent Person (and, if applicable, the Second Competent Person). All expenses associated with the Competent Person's Report (and, if applicable, the Second Competent Person's Report) will be paid by Rockhopper.

   3.4        Contingent Consideration payable

(a) The Total Contingent Consideration Amount shall be calculated as GBP0.59 multiplied by the Agreed Resources (and not just the excess over 20 million barrels of Liquid Hydrocarbons), subject always to the Contingent Consideration Cap.

(b) Therefore, the Contingent Consideration payable per Relevant Share shall be equal to the Total Contingent Consideration Amount divided by the aggregate number of Relevant Shares.

(c) The total amount of the HQ Prospect 2C Contingent Resources (if any) is uncertain and therefore the amount of the Contingent Consideration (if any) which may become payable cannot be quantified at this time. There can be no guarantee that all or any Contingent Consideration will become payable in connection with the Acquisition.

(d) By way of example only, the amount payable in various circumstances pursuant to the Contingent Consideration Offer (assuming a fully diluted ordinary share capital of MOG of 451,192,831 ordinary shares) is set out below:

   3.5        Payment of the Contingent Consideration 
   (a)      The Contingent Consideration, if payable, will be paid to the holders of Relevant Shares.

(b) The obligation to pay the Contingent Consideration is and will remain a non-interest bearing and unsecured obligation of Rockhopper. Accordingly, if the Contingent Consideration becomes payable and there is a default in payment (on insolvency of Rockhopper or otherwise), Relevant Shareholders will rank as unsecured creditors only in respect of their entitlement to the Contingent Consideration.

(c) The precise timing for the payment of the Contingent Consideration (if any) cannot be ascertained at the time of this announcement. However, it shall be paid within 14 days (or such other date as the Panel may allow) of the Competent Person's Report (or, if commissioned, the Second Competent Person's Report) being provided to Rockhopper by the Competent Person (or the Second Competent Person, as applicable), provided that in no circumstances will the Contingent Consideration be calculated or paid before the date falling three months from the Effective Date, in order to allow all options and awards under the MOG Share Plans to be exercised or to have lapsed.

   4.          Information on Rockhopper

Rockhopper was admitted to AIM in 2005 with its principal asset being 5,800 km(2) of prospective oil and gas acreage in the North Falkland Basin. Rockhopper has, as an operator, successfully evaluated, drilled and appraised this acreage culminating in up to approximately 450 mmbbl of 2C Contingent Resources being discovered in Sea Lion and its satellite fields, if a gas cap does not exist on the western flank of Sea Lion. Following the farm-out of 60 per cent of its principal acreage and relinquishment of operatorship to Premier Oil in 2012, Rockhopper is an active partner in the development of the Sea Lion field and sub-surface lead for further exploration in the North Falkland Basin for the joint venture with Premier Oil. The farm-out to Premier Oil has given Rockhopper a robust balance sheet, with current cash of approximately US$ 250 million (GBP147 million). Premier Oil is currently seeking further industry partners to participate in the development of Sea Lion prior to its project sanction and Rockhopper is actively assisting in this process. Rockhopper is currently looking forward to participating in the next phase of exploration drilling in the Falklands which, is expected to commence in the first half of 2015. Rockhopper has already completed the planning for the four firm wells to be drilled on its acreage, targeting over 500 mmbbl of Pmean STOIIP net to Rockhopper.

   5.          Background to and reasons for the Acquisition

5.1 Following the completion of the farm-out of Sea Lion to Premier Oil and having conducted the preparation for the next exploration campaign in the North Falkland Basin, the Rockhopper Directors set about planning for the next phase of Rockhopper's growth, including a review of opportunities outside the North Falkland Basin. The Rockhopper Directors wish to harness the skills and experience that Rockhopper has acquired in the process of maturing the North Falkland Basin from an area of prospective acreage through to a major new oil development and have determined that any opportunity outside the North Falklands Basin must contain significant appraisal and exploration potential. The Rockhopper Directors are also mindful of establishing a balanced portfolio of assets and therefore any opportunity outside the North Falklands Basin should also give Rockhopper exposure to an element of production or near term production. Importantly, the Rockhopper Directors wish Rockhopper to operate or to have strong influence, where possible, over a significant proportion of the assets it is to acquire, in particular at the exploration and appraisal stage and which are part of a regional and geographically focused portfolio.

5.2 The Rockhopper Directors believe that Rockhopper's relative balance sheet strength could be efficiently used to unlock value accretive opportunities that have previously suffered from lack of access to financing. However, the Rockhopper Directors do not wish to see significant cash resources being expended or large work commitments being entered into until such time as there is further clarity around the Sea Lion development and Rockhopper's remaining funding requirements. The Rockhopper Directors remain cognisant that the North Falklands will remain Rockhopper's core focus for the foreseeable future and financial resources must remain available to assist in its development as necessary and to fund Rockhopper's share of the expected 2015 exploration drilling campaign in the North Falkland Basin.

5.3 The Rockhopper Directors believe the acquisition of MOG represents a compelling opportunity that fits well within its selected criteria, for the following reasons:

(a) as part of the Acquisition, Rockhopper will acquire a well understood production base which will generate immediate revenue to Rockhopper;

(b) as part of the Initial Consideration Offer value of GBP29.3 million, Rockhopper will be acquiring significant net cash, EUR 12.4 million (GBP10.0 million) as at 31 December 2013;

(d) it provides Rockhopper with a mixture of low, medium and high risk exploration opportunities;

(e) it provides Rockhopper with an entry into a region (Mediterranean / North Africa) where it sees significant potential for growth and where over time, it believes a substantial business can be built; and

(f) management believes the Acquisition represents a relatively low cost entry into a new region with limited commitments, limited cash impact and value supported by existing cash and existing producing assets.

5.4 Pursuant to the Initial Consideration Offer, which values MOG at GBP29.3 million, Rockhopper will be immediately acquiring significant net cash, which as at 31 December 2013 was EUR 12.4 million (GBP10.0 million) held by MOG on its balance sheet. Additionally, Rockhopper will be acquiring existing production that will provide the Enlarged Group with immediate revenue. Production from MOG's principal production asset, being the Guendalina offshore field, was 35,650 scm per day net to MOG as of 13 May 2014, which is an increase of 23 per cent above average net production for December 2013, as announced by MOG on 13 May 2014.

5.5 Rockhopper sees significant potential in the 100 per cent owned and operated Ombrina Mare project, which already has 2C Contingent Resources of 26.5 mmboe with the ability for this to be increased materially depending on the results of the next planned appraisal well. Rockhopper has spent time understanding the Ombrina Mare discovery and Rockhopper believes that with additional technical and engineering work, combined with some patience and funds available to support an appraisal of the discovery, its value can be significantly increased over time.

5.6 As a result of the Acquisition, Rockhopper will be acquiring in aggregate oil and gas reserves and contingent resources of approximately 33 mmboe therefore materially increasing its current resource base. The net acquisition cost, based on the Initial Consideration only, of these additional reserves and resources to Rockhopper is equivalent to less than US$ 1 (GBP0.59) per boe.

5.7 Rockhopper had identified a number of low to high risk exploration opportunities, with unrisked prospective resources of over 150 mmboe, from within the MOG portfolio. In its assessment of MOG, Rockhopper has ascribed no value to the HQ Exploration Well (which is soon to be drilled by Genel) as part of the Initial Consideration Offer. Instead it is offering an element of contingent consideration depending on the success of this well which is described in more detail in paragraph 3. Regardless of the outcome of the HQ Exploration Well, Rockhopper will have gained access to potential high-impact exploration assets elsewhere in the MOG portfolio including the Monte Grosso exploration prospect in the Southern Apennines region of Italy, which has a gross Pmean prospective resource of more than 200 mmstb and a geological chance of success of 23 per cent and Malta Area 3 on which technical work continues with MOG's partner Cairn and where 1714 km of 2D broadband seismic data has just been acquired.

5.8 Importantly, Rockhopper will be entering into a region where it sees significant potential for growth and where, over time, it believes a substantial business can be built. Rockhopper would seek to leverage the agreement to work together with Genel in the area of mutual interest covering the offshore basins of Libya, Malta and Tunisia. Following the Acquisition, Rockhopper will be well placed to take advantage of other opportunities that emerge in the region and, for example, will look carefully at participating in any new licensing rounds similar to the one recently announced by MOG for three blocks in offshore Montenegro. Additionally, Rockhopper will seek to build upon the strategic relationships, acquired as part of the Acquisition, with other high quality operators and partners in the region including ENI S.p.A., Total S.A., Cairn Energy plc and Genel.

5.9 The Rockhopper Directors and management already have significant experience of working in the Mediterranean and North Africa regions through previous roles in other oil companies which will combine well with the expertise of MOG's management. Most notably, Rockhopper's team had exposure to this region through involvement with a number of operating companies including Petrocanada, BG Group plc, Melrose Resources plc and Veba Oil & Gas GmbH along with extensive non-operated and new ventures experience across the region.

5.10 The Rockhopper Directors believe that the Cash Consideration payable, when taken together with the cash on MOG's balance sheet (which was approximately EUR 12.4 million (GBP10.0 million) as of 31 December 2013) and the issue of 7,758,606 Rockhopper Consideration Shares (which represents a dilution of less than 2.65 per cent) is a reasonable price to secure a portfolio of assets of this nature. Any work commitments associated with the MOG portfolio are relatively small and Rockhopper will continue to manage its cash resources prudently. The Contingent Consideration Offer is limited to a maximum of GBP16.0 million and will only become payable if a commercial discovery is made which is independently certified as exceeding 20 mmbbl of 2C Contingent Resources of Liquid Hydrocarbons on a Net Basis, which Rockhopper believes would be highly likely to represent a commercially viable project.

5.11 Whilst this acquisition will be material to Rockhopper, it is not expected to distract management from Rockhopper's core focus of the North Falklands Basin, where Rockhopper will continue to assist the operator in advancing the development of Sea Lion and eagerly awaits the expected 2015 exploration drilling campaign. The Rockhopper Directors have ambitions to grow Rockhopper into a leading international exploration and production company and would consider moving Rockhopper to the Main Market of the London Stock Exchange in due course. The Rockhopper Directors believe that the Acquisition will be likely to improve Rockhopper's eligibility for such a move to the Main Market.

   6.          Recommendation

6.1 The MOG Directors, who have been so advised by RBC, as the independent financial adviser for the purposes of Rule 3 of the Takeover Code, consider the terms of the Acquisition to be fair and reasonable. In providing its advice to the MOG Directors, RBC has taken into account the commercial assessments of the MOG Directors.

6.2 Accordingly, the MOG Directors intend to recommend unanimously that MOG Shareholders vote in favour of the resolutions to be proposed at the Court Meeting and the General Meeting which are to be convened to approve and implement the Acquisition. The MOG Directors have irrevocably undertaken to approve the necessary resolutions in respect of their entire beneficial holdings in MOG, which, in aggregate, amount to 2,588,171 MOG Shares, representing approximately 0.60 per cent of the existing issued ordinary share capital of MOG.

   7.          Background to and reasons for the recommendation

7.1 MOG has a proven track record of identifying, developing and monetising oil and gas assets in the Mediterranean region. MOG has brought together an experienced team from some of the world's leading energy companies to manage its operations and transactions to the highest industry standards. MOG's strategy is to balance investments across the value chain and to invest in strong partnerships within the region. As a result, MOG has built a valuable portfolio of exploration, appraisal and production opportunities in Italy, Malta and France, in partnership with some of the world's leading energy companies.

7.2 MOG is exploring frontier acreage offshore Malta. MOG holds a 25 per cent working interest in the Area 4 production sharing contract offshore Malta where the operator, a wholly owned subsidiary of Genel (75 per cent working interest, operator), is expected to soon start drilling operations on the HQ Exploration Well. This well is targeting 27 million barrels of certified mean prospective resources net to MOG and is expected to reach the target reservoir during Q3 2014. The Contingent Consideration component of the Acquisition is structured to reward a positive result from this well.

7.3 MOG's flagship project, Ombrina Mare (MOG 100 per cent working interest, operator), was certified by an independent competent person in 2013 as containing 25.1 million barrels of 2C Contingent Resources (oil) and 8.0 billion cubic feet of 2C Contingent Resources (gas). This project continues to await the award of environmental permits and the associated production concession that will enable the project to move ahead with the drilling of an appraisal well required to prove any resource upside and to optimise plans for the development of the asset.

7.4 In 2013, MOG's Guendalina offshore gas field (MOG 20 per cent working interest, ENI S.p.A. operator) experienced production challenges that resulted in two of the three producing strings being shut-in, resulting in a 42 per cent reduction in production for MOG compared to the prior year and an associated 48 per cent reduction in revenue. Production has been restored in one of the two affected strings, and production from the field has increased 23 per cent since December 2013. Nonetheless, the MOG Directors believe a further increase in production, to restore the full economic value of the field, will require further capital investment.

7.5 While the MOG Directors believe in the future growth potential of MOG, having considered the Initial Consideration Offer in light of the business risks, particularly the timing and operational challenges of progressing key assets, combined with the funding risk inherent in the public markets and the timescale associated with realising value from MOG's assets, they consider that the Initial Consideration Offer provides MOG Shareholders with attractive and certain value. In addition, the Contingent Consideration gives MOG Shareholders the ability to benefit from a positive result from the HQ Exploration Well which the MOG Directors believe is important given the potential size and timing of this target.

7.6 Accordingly, the MOG Directors have concluded that the Acquisition is fair and reasonable and intend to recommend unanimously that MOG Shareholders vote in favour of the resolutions at the Court Meeting and the General Meeting to approve and implement the Scheme.

   8.          The Deferred Shares

8.1 MOG has in issue 38,912,736 deferred shares of 19 pence each (the "Deferred Shares"), which were created as part of a reorganisation of MOG's share capital in 2011. The Deferred Shares are not listed on any exchange and effectively have no rights, in particular they do not confer on their holders any right to any dividend or distribution nor the right to receive notice of, attend, speak or vote at general meetings of MOG.

8.2 The Deferred Shares will not form part of, and will be unaffected by, the Acquisition and the Scheme.

   9.          Information on MOG

9.1 MOG is an AIM-quoted exploration and production company with operations in Italy, Malta and France. MOG produces natural gas onshore and offshore in Italy and has a balanced portfolio of exploration, appraisal and development opportunities with reserves and contingent resources of 33 mmboe and total unrisked prospective resources of over 1,200 mmboe. Net production from the Guendalina field, MOG's principal production asset, was 35,650 scm per day as of 13 May 2014. Development activities are focused on MOG's 100 per cent operated interest in the offshore Italian Ombrina Mare discovery, which has 2C Contingent Resources of 26.5 mmboe. MOG is also undertaking high-impact exploration offshore Malta and will drill the HQ Prospect in 2014 targeting mean net unrisked resources of 27 mmboe. MOG also holds additional development and exploration opportunities in Italy, Malta and France.

9.2 In the year to 31 December 2013, MOG recorded a loss before tax from continuing operations of EUR 5.59 million and as at 31 December 2013 had net assets of EUR 50.49 million (GBP40.89 million).

   10.        Irrevocable Undertakings

10.1 The MOG Directors have irrevocably undertaken to approve the necessary resolutions in respect of their entire beneficial holdings in MOG, which, in aggregate, amount to 2,588,171 MOG Shares, representing approximately 0.60 per cent of the existing issued ordinary share capital of MOG. The MOG Directors have also irrevocably undertaken to approve the necessary resolutions in respect of their entire holdings of options and awards in the MOG Share Plans (totalling 18,955,000 MOG Shares), if such options and awards are exercised or vest prior to the Scheme Voting Record Time. These irrevocable undertakings will cease to be binding only if the Scheme lapses or is withdrawn and remain binding if a higher competing offer for MOG is made.

10.2 In addition, Rockhopper has received irrevocable undertakings to vote in favour of the Scheme at the Court Meeting and in favour of the resolution at the General Meeting from certain MOG Shareholders representing, in aggregate, approximately 31.36 per cent of the existing issued ordinary share capital of MOG, as follows:

-- OZ ELS Master Fund Limited in respect of its entire holdings of MOG Shares, representing approximately 0.42 per cent of the existing issued ordinary share capital of MOG;

-- OZ Global Spec Invest Master Fund LP in respect of its entire holdings of MOG Shares, representing approximately 0.78 per cent of the existing issued ordinary share capital of MOG;

-- OZ Europe Master Fund Limited in respect of its entire holdings of MOG Shares, representing approximately 8.30 per cent of the existing issued ordinary share capital of MOG;

-- OZ Master Fund Limited in respect of its entire holdings of MOG Shares, representing approximately 18.68 per cent of the existing issued ordinary share capital of MOG;

-- Miles Donnelly in respect of his entire holding of MOG Shares, representing approximately 0.04 per cent of the existing issued ordinary share capital of MOG; and

-- Contessa Properties Limited (a company ultimately controlled by Miles Donnelly) in respect of its entire holding of MOG Shares, representing approximately 3.14 per cent of the existing issued ordinary share capital of MOG.

These irrevocable undertakings will cease to be binding only if the Scheme lapses, is withdrawn or if a competing offer for MOG is made which represents the increase to the Initial Consideration and the Contingent Consideration set out in Appendix 3 hereof.

10.3 Therefore, as at the date of this announcement, Rockhopper has received irrevocable undertakings to vote in favour of the Scheme at the Court Meeting and in favour of the resolution at the General Meeting in respect of a total of 137,885,951 MOG Shares, representing, in aggregate, approximately 31.96 per cent of MOG's existing issued ordinary share capital.

   10.4      Further details of the irrevocable undertakings are provided in Appendix 3. 
   11.        Conditions

The Scheme will be subject to the conditions and further terms set out in Appendix 1 and the full terms and conditions which will be set out in the Scheme Document. In particular, the Scheme is conditional on the Government of the Republic of Malta (through its relevant department or agency), either confirming that consent is not required for the indirect change of control of Melita Exploration or, if it is required, giving such consent.

   12.        Management, employees and locations of business

12.1 Rockhopper attaches great importance to the active participation and continued commitment of MOG's employees. Accordingly, Rockhopper confirms that, following the Scheme becoming effective, the existing contractual and statutory employment rights, including in relation to pensions, of all MOG employees will be honoured.

12.2 Following the Effective Date, Rockhopper intends to conduct a review of the business of the Enlarged Group to identify and achieve operational and administrative synergies although, in light of Rockhopper's lack of presence in the Mediterranean, the Rockhopper Directors anticipate that a significant proportion of MOG's employees in the region will be retained in the business.

12.3 It is Rockhopper's current intention to maintain the location of MOG's places of business, save for the London office of MOG which will be closed. Rockhopper currently expects that closure to result in a reduction of head count of the MOG Group's administrative functions in London in order to achieve efficiencies within the Enlarged Group. It is anticipated that the Rome office of MOG will become the administrative and operational centre for the Mediterranean business of the Enlarged Group.

12.4 The MOG Directors have confirmed that it is their intention to resign as directors of MOG following the Effective Date. It is anticipated that certain MOG Directors may become consultants for a transitional period following the Effective Date.

   13.        Structure of the Acquisition

13.1 It is intended that the Acquisition will be effected by means of a Court-sanctioned scheme of arrangement of MOG under Part 26 of the Companies Act (including the Capital Reduction under section 641 of the Companies Act).

13.2 The purpose of the Scheme is to provide for Rockhopper to become the owner of the entire issued and to be issued ordinary share capital of MOG. This is to be achieved by the cancellation of the Scheme Shares and the application of the reserve arising from such cancellation in paying up in full such number of new ordinary shares in MOG, which is equal to the number of Scheme Shares so cancelled, and issuing such new MOG ordinary shares to Rockhopper. In consideration for this, the Scheme Shareholders will receive cash consideration and Rockhopper Consideration Shares on the basis set out in paragraph 2 of this announcement, together with the right to receive the Contingent Consideration pursuant to the Contingent Consideration Offer. The cancellation of those Scheme Shares and the subsequent issue of new MOG Shares to Rockhopper will result in MOG becoming a wholly-owned subsidiary of Rockhopper.

13.3 To become effective, the Scheme must be approved by a majority in number of those Scheme Shareholders entitled to vote and present and voting at the Court Meeting (either in person or by proxy) representing at least 75 per cent in value of the Scheme Shares held by such Scheme Shareholders. In addition, the implementation of the Scheme requires approval by the passing of a special resolution by MOG Shareholders at the General Meeting to be held immediately after the Court Meeting.

13.4 The Scheme and the Capital Reduction must also be sanctioned by the Court. All Scheme Shareholders are entitled to attend the Court Hearings in person or through counsel to support or oppose the sanctioning of the Scheme. The Scheme and Capital Reduction will only become effective upon delivery to the Registrar of Companies of copies of the Court Orders and (in the case of the Capital Reduction), the statement of capital (and, if the Court so orders for the Capital Reduction to take effect, upon registration by him of the Reduction Court Order and the statement of capital).

13.5 The Scheme will also be subject to certain Conditions and further terms referred to in Appendix 1 to this announcement and to be set out in the Scheme Document.

13.6 Rockhopper reserves the right to switch from implementing the Acquisition by means of a scheme of arrangement under Part 26 of the Companies Act to a Takeover Offer, in accordance with paragraph 8 of Appendix 7 of the Takeover Code, with the consent of the Panel.

13.7 Subject to satisfaction of the Conditions, the Scheme is expected to become effective on or around 5 August 2014. The Acquisition will lapse if the Scheme does not become effective by 23 November 2014 (or such later date as may, with the consent of the Panel (if required), be agreed between Rockhopper and MOG) (the "Long Stop Date"), provided however that this deadline may be waived by Rockhopper.

13.8 Upon the Scheme becoming effective, it will be binding on all Scheme Shareholders, irrespective of whether or not they were present or voted at the Court Meeting or the General Meeting and, if they did vote, whether or not they voted in favour of or against the resolutions proposed at those meetings.

13.9 Further details of the Scheme will be set out in the Scheme Document, together with notices of the Court Meeting and the General Meeting and the accompanying Forms of Proxy, which are expected to be despatched to MOG Shareholders as soon as reasonably practicable and in any event by 20 June 2014, unless otherwise agreed with the Panel.

   14.        MOG Share Plans

Participants in the MOG Share Plans will be contacted regarding the effect of the Acquisition on their rights under the MOG Share Plans in accordance with the terms of the relevant plan rules and appropriate proposals will be made to such participants in due course.

Participants in the MOG Share Plans who exercise their options will be entitled to participate in the Initial Consideration Offer and the Contingent Consideration Offer.

   15.        Financing the Acquisition

15.1 The cash consideration element of the Initial Consideration Offer and the Total Contingent Consideration Amount will be financed from existing cash resources of Rockhopper.

15.2 Canaccord, as financial adviser to Rockhopper, is satisfied that sufficient resources are available to satisfy in full (i) the cash consideration payable under the Initial Consideration Offer and (ii) the maximum amount of the cash consideration payable under the Contingent Consideration Offer under the terms of the Acquisition.

   16.        Admission, dealings and settlement of the Rockhopper Consideration Shares

An application, conditional on the Scheme becoming effective, will be made to the London Stock Exchange for the Rockhopper Consideration Shares to be admitted to trading on AIM. It is anticipated that Admission will become effective, and that dealings for normal settlement in the Rockhopper Consideration Shares will commence, no later than 8 a.m. on the Business Day after the Effective Date.

   17.        Delisting of the MOG Shares

17.1 It is intended that dealings in MOG Shares will be suspended at the Reduction Record Time and that no transfers of MOG Shares will be registered after that time. Application will be made to the London Stock Exchange for the cancellation of the admission to trading of the MOG Shares to AIM upon or shortly after the Effective Date.

17.2 When the Scheme becomes effective in accordance with its terms, the MOG Shares will be cancelled. At that point, share certificates in respect of MOG Shares will cease to be valid and entitlements to MOG Shares held within the CREST system will be cancelled.

   18.        Offer-related arrangements

MOG and Rockhopper entered into a confidentiality agreement on 11 February 2014. Pursuant to this agreement, the parties undertook to keep confidential information relating to Rockhopper, MOG and their respective subsidiaries and businesses and not to disclose it to third parties (other than certain permitted recipients), unless required by law or regulation. These obligations will remain in force until the Scheme becomes Effective or until 11 February 2016, save in respect of certain limited information which shall remain confidential indefinitely. The agreement includes a 12 month mutual non-solicitation undertaking in respect of Rockhopper and MOG senior employees and officers.

   19.        Opening position disclosures and interests

19.1 Rockhopper will make, on the date hereof, an Opening Position Disclosure, setting out the details required to be disclosed by it under Rule 8.1(a) of the Takeover Code.

19.2 MOG will make, on the date hereof, an Opening Position Disclosure, setting out details required to be disclosed by it under Rule 8.2(a) of the Takeover Code.

   20.        Overseas shareholders

20.1 The availability of the Rockhopper Consideration Shares under the terms of the Acquisition to persons not resident in the United Kingdom may be prohibited or affected by the laws and regulations of the relevant jurisdictions. Such persons should inform themselves about and observe any applicable requirements. Further details in relation to Overseas Shareholders will be contained in the Scheme Document.

   20.2      This announcement does not constitute an offer or invitation to purchase any securities.
