Item 7.01 Regulation FD Disclosure.

     On December 11, 2009, Superior Energy Services, Inc. (the “Company”) and Superior Energy Services (UK) Limited (“Superior UK”), a newly formed indirect, wholly-owned subsidiary of the Company, entered into an Implementation Agreement (the “Implementation Agreement”) with Hallin Marine Subsea International Plc (“Hallin”), a company incorporated under the laws of the Isle of Man, to acquire Hallin for a price of 233 pence in cash per Hallin share (the “Offer”). The Offer values Hallin’s existing issued and to be issued fully diluted ordinary share capital at approximately £103.5 million (approximately $168.3 million based upon an exchange rate of £1.00: US$1.626 at the close of business on December 10, 2009). Also on December 11, 2009, Superior UK and Hallin issued an announcement (the “Rule 2.5 Announcement”) pursuant to Rule 2.5 of the United Kingdom City Code on Takeovers and Mergers, and the Company issued a press release, in each case announcing the Offer.

     The Offer is to be effected by way of a scheme of arrangement under section 152 of the Isle of Man Companies Act 1931, as amended, subject to approval by the High Court of Justice of the Isle of Man and a majority in number representing 75% or more in value of the holders of the ordinary shares in the capital of Hallin entitled to vote as further described in the Rule 2.5 Announcement, as well as other customary conditions being satisfied and/or waived by the parties.

     The Implementation Agreement will govern the relationship of the parties during the period from the publication of the Rule 2.5 Announcement until the acquisition by Superior UK of the entire issued and to be issued share capital of Hallin becomes effective or the Offer lapses or is withdrawn.

     The Company is furnishing the Rule 2.5 Announcement and the Company’s press release as Exhibits 2.2 and 99.1, respectively, both of which are incorporated herein by reference. The information contained in this Item 7.01, including Exhibits 2.2 and 99.1 hereto, is furnished in accordance with General Instruction B.2. of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

(2)		HALLIN MARINE SUBSEA INTERNATIONAL PLC, a company incorporated under the laws of the Isle of Man with registered number 107479C and whose registered office is at International House, Castle Hill, Victoria Road, Douglas, Isle of Man, IM2 4RB (“Hallin”); and
(3)		SUPERIOR ENERGY SERVICES, INC. a company incorporated under the laws of Delaware having its principal place of business at 601 Poydras, Suite 2400, New Orleans, Louisiana (“Parent”).

WHEREAS:

(A)		The Parent intends to make an offer for the shares of Hallin and proposes to implement such offer on the terms and subject to the conditions set out in the Press Announcement (as defined below) through Bidco, its wholly owned indirect subsidiary.
(B)		The parties have agreed to implement such offer by way of a scheme of arrangement although Parent and Bidco reserve the right, as set out in this deed of agreement, to elect to implement such offer by making a takeover offer for the entire issued and to be issued share capital of Hallin.
(C)		The parties have agreed to take certain steps to effect completion of the transaction and wish to enter into this deed of agreement to record their respective obligations relating to such matters.

THIS DEED WITNESSES as follows:

1		INTERPRETATION
1.1		In addition to terms defined elsewhere in this agreement, the definitions and other provisions in the schedule headed “Interpretation” apply throughout this Agreement, unless the contrary intention appears.
1.2		In this Agreement, unless the contrary intention appears, a reference to a Clause, Subclause or Schedule is a reference to a clause, subclause or schedule to this Agreement. The Schedules form part of this Agreement.
1.3		The headings in this Agreement do not affect its interpretation.
2		PRESS ANNOUNCEMENT
		The parties shall procure the release of the Press Announcement at or before 9.00 am on 11 December 2009 or such other time and date as may be agreed by the parties provided the Directors have not before then resolved to withdraw, amend or vary their recommendation of the Acquisition and notified Bidco of such resolution. Clauses 3 (Implementation of the

Scheme), 4 (Preparation of Documentation), 5 (Information and Financing), 6 (Conduct of Business) and 8 (Competing Proposals) of this Agreement shall have no effect until and unless release of the Press Announcement occurs in accordance with this Agreement.

3		IMPLEMENTATION OF THE SCHEME
3.1		Subject as provided in this Agreement, each of Hallin and Bidco undertakes to each other that it will:

	(a)		co-operate and take or cause to be taken all such steps as are within its power and are both reasonable and necessary to implement the Scheme in accordance with the Timetable as soon as reasonably practicable; and
	(b)		keep each other informed and consult each other as to the progress of the Scheme.

3.2

Without prejudice to the generality of the foregoing Clause 3.1 Hallin undertakes:

	(a)		not to seek to amend the Timetable without the consent of Bidco (such consent not to be unreasonably withheld or delayed); and
	(b)		not to allot or issue or grant any options over any Hallin Shares between the date of this Agreement and the time at which the Scheme becomes effective.

3.3		Hallin agrees that the Scheme Document shall incorporate a unanimous recommendation of the Directors to Hallin Shareholders to vote in favour of the Scheme and the Hallin Resolution in the form set out in the Press Announcement, except to the extent that the Directors have determined (acting in good faith and having taken legal and financial advice to that effect) that such recommendation should not be given (or should be withdrawn or modified) having regard to their fiduciary duties as directors of Hallin.
3.4		Hallin confirms to Bidco that the Scheme will contain provisions in accordance with the terms and conditions set out in the Press Announcement and other terms and conditions only as further agreed among Hallin and Bidco. Once the Scheme Document has been posted, save as required by law or regulation or the Panel or the London Stock Exchange or any court of competent jurisdiction, Hallin will not amend the Scheme without the prior written consent of Bidco (such consent not to be unreasonably withheld or delayed).
3.5		The obligations of the parties to implement the Scheme or, if applicable, the Offer are subject to satisfaction (or waiver by Bidco) of the Conditions. Hallin undertakes to Bidco that it will procure that the Final Court Hearing is postponed if, at 6.00 pm on the Business Day preceding the date of the Final Court Hearing appearing on the Timetable, Bidco has notified Hallin in writing that it has not waived or treated as satisfied each Condition (such notification to include details of the reasons why any particular Condition has not been waived or satisfied) and if such notification is given at that time, Hallin undertakes not to arrange for the Final Court Hearing to be held on a new date without the prior consent of Bidco.
3.6		Without prejudice to Clause 3.1 above, Bidco undertakes to use its reasonable endeavours to, and to procure that their directors and relevant professional advisers assist to, prepare all such documents and take all such steps as are necessary or desirable for the purposes of obtaining all Clearances as soon as reasonably practicable and in any event within the Timetable. Bidco undertakes to keep Hallin informed promptly of developments which are material or potentially material to the obtaining of Clearances by 22 January 2010 and to disclose to Hallin material correspondence with any relevant Competition Authority (subject

		to redaction of confidential information). The parties will consult with the Panel from time to time as necessary in order to keep the Panel informed and, where appropriate, seek the consent of the Panel as to the Timetable and the process to obtain the Clearances.
3.7		Bidco shall undertake to the Court to be bound by the terms of the Scheme insofar as it relates to Bidco, including as to the discharge of the consideration of the Acquisition.
3.8		Parent and Bidco will procure that the directors of Bidco accept responsibility for relevant information in the Scheme Document in accordance with the terms of the relevant responsibility statement set out in the Scheme Document.
3.9		Hallin will procure that the Directors accept responsibility or relevant information in the Scheme Document in accordance with the terms of the relevant responsibility statement set out in the Scheme Document.
4		PREPARATION OF DOCUMENTATION
4.1		As soon as reasonably practicable following the date hereof, Hallin and Bidco shall complete the preparation of the Scheme Document and shall each work diligently with a view to finalising it no later than 6.00 pm on 11 December 2009 and posting it no later than 7.00 pm on 12 December 2009.
4.2		Hallin agrees to consult with Bidco as to the form and content of the Scheme Document, to seek the approval (not to be unreasonably withheld or delayed) of Bidco of the content of the Scheme Document before it is posted and to afford Bidco sufficient time to consider such document in order to give such approval. Bidco undertakes to provide Hallin promptly with all such information about themselves and their shareholders as may reasonably be required for inclusion in the Scheme Document and to provide all such other assistance as Hallin may reasonably require in connection with the preparation of the Scheme Document, including access to, and ensuring the provision of reasonable assistance by, relevant professional advisers.
5		INFORMATION AND FINANCING
5.1		Without prejudice to the specific provisions of Clauses 5.2 and 5.3 below, Hallin shall (and shall procure that each other member of the Hallin Group shall) upon reasonable notice given by or on behalf of Bidco provide Bidco with all information, cooperation and assistance that Bidco may reasonably require for the purposes of the Acquisition and the financing of the Acquisition and in particular, but not limited to:

	(a)		effecting introductions to and making requests of any relevant third parties, reasonably requested by Bidco or the Parent;
	(b)		providing net asset statements, projected balance sheets and other relevant financial information for each member of the Hallin Group; and
	(c)		assisting in any approaches to any regulatory body whose consent may be required for the Acquisition or the charging of any assets of the Hallin Group for the purpose of financing the Acquisition.
	(d)		Hallin shall (and shall procure that each member of the Hallin Group shall) upon reasonable notice given by or on behalf of Bidco, provide such assistance as Bidco may reasonably request for Bidco and Parent to make preparatory arrangements for any post-acquisition restructuring or financing of the Hallin Group and co-operating with any requirements of the providers of such finance in each case so

that implementation can take place on or as soon as reasonably practicable after the Effective Date.

5.2		Without prejudice to the generality of Clause 5.1, Hallin shall, and shall procure that other members of the Hallin Group shall upon reasonable notice, to the extent requested by Bidco do all things reasonably necessary to ensure that the existing non-executive directors of Hallin shall resign (without claim against Hallin Group other than in respect of any outstanding director’s fees and unreimbursed expenses) and that any persons nominated by Bidco are appointed as directors of members of the Hallin Group in substitution for the existing non-executive directors, in each case, with immediate effect from the Effective Date.
5.3		For the avoidance of doubt, nothing contained in this Clause 5 shall require Hallin or any of its personnel to take any action which could:

	(a)		expose such person to personal liability (including criminal liability) to Bidco or any other person; or
	(b)		result in any breach of any legal requirement or rule; or
	(c)		be irrevocable, or revocable only by incurring further material costs, were the Scheme or Offer not to be completed,

RECOMMENDED TAKEOVER FOR CASH

of

HALLIN MARINE SUBSEA INTERNATIONAL PLC
by
SUPERIOR ENERGY SERVICES (UK) LIMITED
a wholly-owned indirect subsidiary of Superior Energy Services, Inc.

to be effected
by way of a scheme of arrangement
under section 152 of the Isle of Man Companies Act 1931

Summary

The Superior UK Board and the Hallin Board are pleased to announce the terms of recommended Proposals for an all cash acquisition by Superior UK of the entire issued and to be issued share capital of Hallin. The Offeror is a wholly-owned indirect subsidiary of Superior and was formed for the purpose of making the Proposals.

•		Superior UK is to acquire Hallin for 233 pence per Hallin Share in cash.
•		The transaction is recommended by the Hallin Board and values the fully diluted share capital of Hallin at approximately £103.5 million.
•		The transaction is to be effected by means of a Scheme of Arrangement, subject to Court and Hallin Shareholder approval.
•		The Scheme is expected to become effective on 26 January 2010.

The Acquisition

•		The boards of Hallin and Superior UK announce that they have reached agreement on the terms of a recommended cash takeover of Hallin by Superior UK (the “Acquisition”). The Acquisition is to be effected by way of a Court sanctioned scheme of arrangement under section 152 of the Isle of Man Companies Act 1931 (the “Scheme”).
•		The Offeror is a wholly-owned indirect subsidiary of Superior and was formed for the purpose of making the Proposals.
•		Under the terms of the Acquisition, Hallin Shareholders will receive 233 pence in cash for each Hallin Share, valuing the existing issued share capital of Hallin at approximately £96.5 million and approximately £103.5 million on a fully diluted basis.

•

The consideration of 233 pence in cash for each Hallin Share represents a premium of approximately:

	•		87.1 per cent. to the Closing Price of 124.5 pence per Hallin Share on 10 December 2009 being the last Business Day prior to the date of this announcement;
	•		94.5 per cent. to the average Closing Price of 119.8 pence per Hallin Share for the six month period prior to 10 December 2009;
	•		109 per cent. to the net asset value per Hallin Share, based on total equity of approximately US$75.0 million included in Hallin’s most recently published (unaudited) statement of its financial position as of 30 June 2009.

Recommendation and shareholder support

•		The Hallin Directors, who have been so advised by Blomfield, consider the terms of the Acquisition to be fair and reasonable. In providing its advice to the Hallin Board, Blomfield has taken into account the Hallin Directors’ commercial assessments. Accordingly, the Hallin Directors unanimously intend to recommend that Hallin Shareholders vote in favour of the Proposals as they have irrevocably undertaken to do in respect of their holdings of 13,123,864 Hallin Shares in aggregate, representing approximately 31.7 per cent. of the existing issued share capital of Hallin.
•		In addition, Superior UK has received irrevocable undertakings from certain institutional investors to vote in favour of the Proposals in respect of 8,700,000 Hallin Shares in aggregate, representing approximately 21.0 per cent. of the existing issued share capital of Hallin.
•		Superior UK has therefore received irrevocable undertakings to vote in favour of the Proposals in respect of 21,823,864 Hallin Shares in aggregate, representing approximately 52.7 per cent. of the existing issued share capital of Hallin.

Future plans for the Hallin Group

•

Hallin offers Superior the opportunity to enhance its position in the subsea well services market through the combination of Superior’s well intervention assets and Hallin’s existing subsea assets, new build vessel programme and international infrastructure.

Financing

•

The Acquisition will be funded using the Superior Group’s currently committed debt financing arranged by JP Morgan Chase Bank, N.A.

Future process

•

The Scheme will be put to Hallin Shareholders for their approval at the Court Meeting and at the Hallin EGM. In order to become effective, the Scheme must be approved by a majority in number representing at least 75 per cent. in value of all Hallin Shares that are voted at the Court Meeting. In addition, the Special Resolution approving the Scheme and amending the Hallin Share Plan and the Articles must be passed by Hallin Shareholders representing 75 per cent. of the votes cast at the Hallin EGM.

•		It is expected that the Scheme Document will be posted on or before 12 December 2009 and that the Court Meeting and the Hallin EGM to approve the Scheme and deal with certain other related matters will be held on 7 January 2010.
•		It is expected that the Scheme will become effective on 26 January 2010, subject to the satisfaction or waiver of all the conditions set out in Appendix I to this announcement.

Rule 2.10

In accordance with Rule 2.10 of the Takeover Code, Hallin confirms that it has 41,404,574 Hallin Shares in issue as at close of business on 10 December 2009. Hallin currently holds no Hallin Shares in Treasury. The ISIN reference for the Hallin Shares is GB00B06N7T09.

Commenting on the Acquisition, Tony Ebel, Chairman of Hallin, said:

“The board of Hallin believe this is an excellent deal for the Company’s shareholders, for the Company itself and for the Company’s employees.

The Acquisition represents fair value for shareholders and will enable Hallin to take full advantage of the opportunities ahead of it as part of a large, global and well-financed group.”

Commenting on the Acquisition, Terry Hall, Chairman and Chief Executive Officer of Superior said:

“In the short-run, this transaction will provide us with more international penetration and expanded entry into the subsea field development and installation market.

Going forward, we believe the combination of Hallin’s experienced management team, existing global infrastructure and Superior’s well intervention experience and integrated solutions approach will serve as a strong platform for expansion into the growing subsea well intervention market worldwide.”

Blomfield, which is authorised and regulated in the United Kingdom by the Financial Services Authority, is acting exclusively for Hallin in relation to the Acquisition. Blomfield will not regard any other person as its client or be responsible to anyone other than Hallin for providing the protections afforded to clients of Blomfield or for providing advice in relation to the Acquisition nor any other matter referred to in this announcement.

This announcement is not an offer to sell or an invitation to purchase any securities or the solicitation of any vote or approval in any jurisdiction. Hallin Shareholders are advised to read carefully the formal documentation in relation to the Acquisition once it has been dispatched.

The distribution of this announcement in jurisdictions other than the United Kingdom and the Isle of Man may be restricted by law and therefore any persons who are subject to the law of any jurisdiction other than the UK and the Isle of Man should inform themselves about, and observe, any applicable requirements. This announcement has been prepared for the purposes of complying with UK and Isle

of Man 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 of the United Kingdom and the Isle of Man.

The Offeror may purchase Hallin Shares otherwise than under the Proposals, such as in the open market or privately negotiated purchases. Such purchases may be made either directly or through a broker and such purchases shall comply with the applicable laws of the United Kingdom and the Isle of Man, as well as the AIM Rules and the Takeover Code. Information about any such purchases will be available from a Regulatory Information Service.

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

Neither the content of Superior or Hallin’s websites (or any other website) nor the content of any website accessible from hyperlinks on any such website is incorporated into, or forms part of, this announcement.

Notice to US investors in Hallin

The Proposals relate to the shares of an Isle of Man company, are subject to UK and Isle of Man disclosure requirements (which are different from those of the US) and are proposed to be made by means of a scheme of arrangement provided for under the Isle of Man Act Companies Act 1931, as amended. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules under the US Exchange Act. Accordingly, the Proposals are subject to the disclosure requirements and practices applicable in the UK and the Isle of Man to schemes of arrangement which differ from the disclosure requirements of the US tender offer rules. Financial information included in this announcement for Hallin has been prepared, unless specifically stated otherwise, in accordance with accounting standards applicable in the UK and the Isle of Man and thus may not be comparable to the financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US. If the Offeror exercises its right to implement the acquisition by way of a takeover offer, the takeover offer will be made in compliance with applicable US laws and regulations.

The receipt of cash pursuant to the Acquisition by a US holder of Hallin Shares as consideration for the transfer of its Hallin Shares pursuant to the Acquisition may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other tax laws. Each holder of Hallin Shares is urged to consult his independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him.

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

Dealing disclosure requirements

Under the provisions of Rule 8.3 of the Takeover Code, if any person is, or becomes, “interested” (directly or indirectly) in 1 per cent. or more of any class of “relevant securities” of Hallin, all “dealings” in any “relevant securities” of Hallin (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by no later than 3.30 p.m. (London time) on the Business Day following the date of the relevant transaction. This

requirement will continue until the date on which the Proposals become effective, lapse or are otherwise withdrawn or on which the “offer period” otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest” in “relevant securities” of Hallin, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Takeover Code, all “dealings” in “relevant securities” of Hallin by the Offeror or Hallin, or by any of their respective “associates”, must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose “relevant securities” “dealings” should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel’s website at www.thetakeoverpanel.org.uk.

“Interests in securities” arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in price of securities. In particular, a person will be treated as having an “interest” by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Takeover Code, which can also be found on the Takeover Panel’s website. If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, you should consult the Takeover Panel.

RECOMMENDED TAKEOVER FOR CASH

of

HALLIN MARINE SUBSEA INTERNATIONAL PLC
by
SUPERIOR ENERGY SERVICES (UK) LIMITED
a wholly-owned indirect subsidiary of Superior Energy Services, Inc.

to be effected
by way of a scheme of arrangement
under section 152 of the Isle of Man Companies Act 1931

1

Introduction

The Superior UK Board and the Hallin Board announce that they have reached agreement on the terms of a recommended cash takeover of Hallin by Superior UK (the “Acquisition”). The Offeror is a wholly-owned indirect subsidiary of Superior Energy Services, Inc and was formed for the purpose of making the Proposals.

The Acquisition

It is intended that the Acquisition be implemented by way of a Court sanctioned Scheme of Arrangement under section 152 of the Isle of Man Companies Act 1931. Under the terms of the Scheme, which will be subject to the conditions and certain terms set out in this announcement and to the further terms to be set out in the Scheme Document, Hallin Shareholders will receive:

for each Hallin Share           233 pence in cash

This consideration represents a premium of approximately:

• 87.1 per cent. to the Closing Price of 124.5 pence per Hallin Share on 10 December 2009 being the last Business Day prior to the date of this announcement;

• 94.5 per cent. to the average Closing Price of 119.8 pence per Hallin Share for the six month period prior to 10 December 2009; and

• 109 per cent. to the net asset value per Hallin Share, based on total equity of approximately US$75.0 million included in Hallin’s most recently published (unaudited) statement of its financial position as of 30 June 2009.

The Acquisition values the entire issued share capital of Hallin at approximately £96.5 million and £103.5 million on a fully diluted basis.

3		Recommendation
		The Hallin Directors, who have been so advised by Blomfield, consider the terms of the Acquisition to be fair and reasonable. In providing its advice, Blomfield has taken into account the Hallin Directors’ commercial assessments.
		Accordingly, the Hallin Directors believe that the terms of the Acquisition are in the best interests of the Hallin Shareholders as a whole and intend unanimously to recommend that Hallin Shareholders vote in favour of the resolutions to be proposed at the Court Meeting and the Hallin EGM.
4		Background to and reasons for the Acquisition
		In Hallin’s interim report for the six months ending 30 June 2009, issued in September this year, Hallin stated its intention was to ‘actively develop the Company and its revenue generating assets, seeking to deliver the best possible performance and growth in a difficult environment.’
		Whilst the current economic climate has resulted in a number of exciting opportunities for Hallin to enhance its operations, the Company has become increasingly restricted by the lack of readily available finance.
		Following an approach by Superior the Hallin Board has recognised that by joining Hallin with a financially strong and successful group, the Company would be considerably better placed to take advantage of opportunities arising during the foreseeable future.
		By linking Hallin’s established operations in its international markets with the considerable operating base of Superior in the United States, coupled with the opportunity to have access to its strong investment capability, the ongoing group will be more readily able to fulfil its potential.
		The Hallin Board believes the Acquisition will be beneficial to all stakeholders, including Hallin’s staff, allowing them greater opportunities.
		Benefits to Hallin and Scheme Shareholders
		Under the Acquisition, Scheme Shareholders will benefit from a fair price in cash (which offers certainty). Hallin will also gain access to Superior’s technical expertise and financial strength. The Acquisition offers Hallin’s employees a chance to become part of a larger, global organisation with a broader range of career development opportunities.
		Benefits to Superior UK
		Superior has followed Hallin’s development and technical successes to date and believes it can positively complement Hallin’s operations and accelerate the growth of the business. Superior’s financial resources would also enable the Hallin Group to take advantage of future business development opportunities in the market to grow the Hallin Group’s position further.
		The Acquisition complements the Superior Group’s existing oilfield services capability and enhances its technical offering, which are already key focus areas for the Superior Group.
5		Reasons for recommending the Acquisition

In the light of these factors, the Hallin Directors considered carefully the approach from Superior. Following a period of due diligence, Superior UK has now put forward a firm proposal to acquire Hallin at 233 pence per Hallin Share. The Hallin Directors, having considered the above factors, believe that 233 pence per Hallin Share offers Hallin Shareholders certain cash value at a substantial premium to its current market value. As a result, the Hallin Directors are unanimously recommending that Hallin Shareholders vote in favour of the Scheme.

6		Irrevocable Undertakings
		Superior UK has received irrevocable undertakings to vote in favour of the Proposals at the Meetings (and if Superior UK exercises its right to acquire the Hallin Shares by means of a takeover offer, to accept such offer) from:-

	•		all of the Hallin Directors in respect of their entire beneficial holdings of Hallin Shares amounting, in aggregate to 13,123,864 Hallin Shares, representing approximately 31.7 per cent. of Hallin’s existing issued share capital;
	•		Damor Investments Limited in respect of its entire beneficial holding of Hallin Shares amounting to 5,000,000 Hallin Shares, representing approximately 12.1 per cent. of Hallin’s existing issued share capital; and
	•		Gresham House PLC in respect of its entire beneficial holding of Hallin Shares amounting to 3,700,000 Hallin Shares, representing approximately 8.9 per cent. of Hallin’s existing issued share capital.

		In aggregate, Superior UK has received irrevocable undertakings to vote in favour of the Proposals in respect of 21,823,864 Hallin Shares, representing approximately 52.7 per cent. of Hallin’s existing issued share capital.
		Further details of these irrevocable undertakings, including the circumstances in which they cease to be binding, are set out in Appendix III to this announcement.
7		Implementation Agreement, non-solicitation and inducement fee

Superior UK and Hallin have entered into the Implementation Agreement, which governs their relationship during the period until the Scheme becomes effective or lapses or is withdrawn. Among other things, the parties have agreed to cooperate with regard to the process to implement the Scheme and Hallin has entered into certain undertakings concerning the conduct of business by Hallin during that period, including, among other things, non-solicitation of an Independent Competing Offer and an inducement fee payable in certain circumstances.

     Non-solicitation

     In the Implementation Agreement Hallin has agreed, among other things, that:

(a)

it will not and will procure that none of the members of the Hallin Group and its and their respective management and professional advisers do not, directly or indirectly, solicit an offer or approach from any party (i) to make or with a view to making an Independent Competing Offer; or (ii) with a view to undertaking a transaction which is an alternative to the Acquisition, other than as required under the Takeover Code; and

(b)

it shall notify Superior UK within twenty-four (24) hours if: (i) it receives an approach from any person with a view to making an Independent Competing Offer Announcement or to making an Independent Competing Offer, or (ii) it becomes aware of any breach by it of the terms of the Implementation Agreement.

The Implementation Agreement terminates in certain circumstances, including:

	(a)		if the Scheme lapses or terminates, unless Superior UK has elected prior to such time, to implement the Acquisition by way of an offer made pursuant to the Takeover Code;
	(b)		if Superior UK elects to implement the Acquisition by way of an offer and such offer is withdrawn or lapses;
	(c)		if at any time prior to satisfaction of the Conditions there is an Independent Competing Offer which subsequently becomes or is declared unconditional in all respects or is otherwise completed; or
	(d)		if the Acquisition has not become effective by 11 March 2010 or such later date (if any) as Superior UK and Hallin may, with the consent of the Takeover Panel, agree and (if required) the Court may approve.

		Inducement fee
		As an inducement to Superior UK to make the Acquisition, Hallin has agreed to pay an inducement fee to Superior UK of the amount invoiced by the advisers of Superior UK at the time of the breach, capped to a maximum of 0.5 per cent. of the Offer Value (exclusive of any VAT payable thereon) upon the occurrence of specified events, including without limitation, in the event that:

	(a)		Hallin terminates the discussions with Superior UK relating to the Acquisition;
	(b)		the Hallin Directors do not unanimously recommend the Acquisition (or the Hallin Directors withdraw, alter, adversely modify or qualify their approval or such recommendation of the Acquisition);
	(c)		provided that Superior UK has not acted unreasonably, the Acquisition, once made, lapses or is withdrawn;
	(d)		Hallin during the Exclusivity Period takes any action which is within Rule 21.1 of the Takeover Code and is material in the context of the Acquisition;
	(e)		Hallin enters into a binding agreement to dispose of any key assets of the business during the Exclusivity Period; or
	(f)		Hallin commits a material breach of its obligations under the Implementation Agreement and the Acquisition subsequently lapses or is withdrawn in accordance with its terms,

and such payment shall be made, within seven days of the event which gives rise to the obligation to make the payment.

Superior has irrevocably undertaken with Hallin to pay to Hallin the sum of 0.5 per cent. of the Offer Value in the event that:

	(a)		Superior UK commits a material breach of its obligations under the Implementation Agreement and the Acquisition subsequently lapses or is withdrawn in accordance with its terms;
	(b)		Superior UK terminates discussions relating to the Acquisition; or
	(c)		provided Hallin has not acted unreasonably, the Acquisition, once made fails to complete for any reason in the absence of an Independent Competing Offer,

		and such payment shall be made within seven days of the event which gives rise to the obligation to make payment.
8		Management and employees
		Superior UK recognises the significant achievements of Hallin’s management team and its employees and attaches considerable importance to retaining the skills and expertise of the management and employees of Hallin and its subsidiaries. Superior UK believes that the current management and employees are an important part of the successful implementation of its plans for Hallin. Superior UK does not therefore intend to make any material changes to Hallin’s staffing levels, nor to any conditions of employment.
		Superior has no current plans to change the locations of Hallin’s places of business, nor does it have any current plans to redeploy the fixed assets of Hallin. As such, in the event the Scheme becomes effective Superior UK has given the Hallin Directors assurances that the existing contractual employment and pension rights of all of Hallin’s employees will at a minimum be fully safeguarded.
9		Information on Hallin
		Hallin was formed in 2003 to acquire the business of Hallin Marine Systems International Ltd, which had been formed by John Giddens in 1998. The Hallin Group provides high quality marine and underwater services to the offshore industry, particularly in support of oil and gas development. Hallin has grown from a US$1 million turnover company in its first year to a US$139 million turnover company in 2008 and was admitted to trading on AIM in April 2005.
		The Hallin Group is an experienced provider of subsea construction and inspection solutions. It employs experienced subsea engineering staff to manage projects using: support vessels; saturation diving systems; air/mixed gas diving spreads and remote operating vehicles (“ROVs”). Hallin owns the principal operating assets of diving systems and ROVs.
		The Hallin Group’s operations cover: South East Asia; India; China; Africa; the Middle East; the US; Russia; Australia and the UK.
		Hallin is divided into four divisions: subsea operations West Division, based in Aberdeen, Scotland; subsea operations East Division, based in Singapore; the Manufacturing Division, also in Singapore where saturation diving systems, air diving systems and ROVs are designed and manufactured; and Prospect Flow Solutions Limited (“Prospect”), the engineering consultancy service to the energy sector with offices in Aberdeen, Derby, Houston and Singapore. A further engineering design centre focusing on robotics is located in the UK at Malton, North Yorkshire.

The majority of the work undertaken by the Hallin Group is in offshore subsea intervention primarily for the oil, gas and renewables industries either contracting directly with the energy majors or through multi-national contractors. Typically the work undertaken by the Hallin Group comprises the design, installation, construction, maintenance, repair or survey of equipment required to transport oil and gas from the seabed. Most of the projects are planned well in advance and Hallin’s role is that of a key contractor, often working as part of a larger team.

2008 Results Highlights

For the financial year ended 31 December 2008, Hallin reported audited profits before taxation of US$35.4 million (2007: US$11.2 million) on audited turnover of US$139.9 million (2007: US$64.8 million). Audited net assets as at 31 December 2008 were US$63.7 million (31 December 2007: US$33.7 million).

Trading Update

Hallin reported unaudited interim results for the six months ended 30 June 2009 on 15 September 2009. The unaudited interim results included profits before taxation of US$10.1 million, despite a non-recurring write-off of US$448,000 (2008: US$13.8 million) on unaudited turnover of US$60.3 million (2008: US$59.6 million). Unaudited net assets at 30 June 2009 were US$75.0 million (30 June 2008: US$44.6 million).

Hallin achieved a gross margin of 29.1 per cent. in the six months ending 30 June 2009, down from 31.8 per cent. in the first half of 2008. Together with a higher level of overhead expenditure, primarily relating to the acquisition of Prospect in August 2008, Hallin reported a lower unaudited EBITDA of US$14.2 million (23.63 per cent.) against US$16.7 million (27.96 per cent.) in the first half of 2008.

Since the 2008 year end Hallin has continued to experience an increasingly competitive trading environment than was experienced in the 2008 financial year, with the consequent effect on margins reflected in the unaudited interim results for the six months ended 30 June 2009. This margin pressure has continued throughout the second half of 2009. Hallin has also seen the seasonal demand of the market in which it operates revert to a more traditional cycle, rather than the unusually beneficial conditions which have been present throughout the last two years.

As stated in Hallin’s 2008 annual report there has been a greater level of pressure on margins across the whole industry during 2009 and this has been particularly evident in Hallin’s Eastern contracting division. The Hallin Directors believe the current industry slowdown is primarily a result of the delays and postponements to a number of projects due to concerns over the price of oil and gas, the difficulty in raising project finance and the additional vessel capacity in the industry. Consequently Hallin’s Eastern division has experienced lower levels of utilisation than originally expected of certain of its non-specialist vessels and accordingly has terminated its short term charter for one of these vessels, with a resultant saving of ongoing charter fees. Hallin’s specialist subsea operations vessels have continued to work at high levels of utilisation.

On 25 November 2009 one of these subsea operations vessels, the Ullswater, suffered a mechanical failure on its starboard main engine and this will require significant off hire time to effect repairs. The reasons for the engine failure are under review, but the Hallin Directors believe that this will be covered under the warranty from the shipyard. As a result of this failure the Ullswater is unable to meet its current contractual obligations as the necessary remedial work is likely to take approximately four weeks to complete.

		Hallin’s Western contracting division has in contrast seen continued high levels of utilisation of its work class ROV assets.
		Hallin’s Engineering division, Prospect, has seen a fall in demand for its specialist engineering and design services in its existing markets. However, Hallin has opened a new Prospect office in Singapore which has been successful in attracting profitable work and the outlook for this business looks encouraging.
		The Manufacturing division continues to build subsea intervention equipment for both Hallin and third parties and has a significant pipeline of opportunities with new customers. However, this division is seeing a lengthening of the decision-making process by clients which may be a reflection of the continued lack of availability of credit in the market.
		Hallin continues to expand its portfolio of specialist subsea assets and further ROVs have continue to be delivered to the contracting divisions, all with the assistance of bank funding. The build of Hallin’s second subsea operations vessel, the Windermere, remains on course for delivery in the first half of 2010.
		As a result of the subdued market in which the Hallin Group is currently operating, the mechanical failure of the Ullswater and the consequent delay in the Hallin Group’s performance of contracts on which the Ullswater is utilised, the Hallin Group’s profitability for the year ended 31 December 2009 is expected to be less than current market expectations.

		Further information on the financing of the Acquisition will be set out in the Scheme Document.
13		Scheme of Arrangement
		The Acquisition is expected to be effected by means of a Scheme of Arrangement between Hallin and the Scheme Shareholders. The purpose of the Scheme is to provide for Superior UK to become the owner of the whole of the issued and to be issued share capital of Hallin. This is to be achieved by transferring the Scheme Shares held by Scheme Shareholders to Superior UK.
		It is expected that the Scheme Document will be posted on 12 December 2009 and that the Scheme will become effective on 26 January 2010, subject to the satisfaction or waiver of all the conditions set out in Appendix I to this announcement.
		The Scheme will be subject to the conditions and certain terms set out in this announcement and to the further terms to be set out in the Scheme Document. In particular, the Scheme requires the approval of Hallin’s Shareholders by the passing of a resolution at the Court Meeting on 7 January 2010. The resolution must be approved by a majority in number of the Hallin Shareholders present and voting, either in person or by proxy, at the Court Meeting representing not less than 75 per cent. in value of the Hallin Shares held by such Hallin Shareholders.
		Implementation of the Scheme, which must occur by 31 May 2010, will also require the passing of the Special Resolution, requiring the approval of Hallin Shareholders representing at least 75 per cent. of the votes cast at the Hallin EGM.
		Following the Meetings, the Scheme must be sanctioned and confirmed by the Court and will only become effective on delivery to the Companies Registry of a copy of the Scheme Court Order.
		Upon the Scheme becoming effective, it will be binding on all Scheme Shareholders, irrespective of whether or not they attended or voted at the Court Meeting or the Hallin EGM.
		Further details of the Proposals (including notices of the Meetings), together with Forms of Proxy, will be contained in the Scheme Document to be issued to Hallin Shareholders, and, for information only, to persons with information rights and participants in the Hallin Share Plan within 28 days of this announcement, unless otherwise agreed with the Takeover Panel. Resolutions to approve the Proposals will be put to Hallin Shareholders at the Meetings.
		Expected timetable of principal events:

		Posting of Scheme Document		12 December 2009
		Court Meeting		7 January 2010
		Hallin EGM		7 January 2010
		Court hearing to sanction the Scheme (if approved by the Hallin Shareholders)		25 January 2010
		Effective Date (if sanction and confirmation of the Court is received)		26 January 2010
		Latest date for consideration to be posted to Hallin Shareholders (if Scheme becomes effective on 26 January 2010)		9 February 2010

		A more detailed timetable will be included within the Scheme Document.
14		Disclosure of interests in Hallin
		Superior UK has received irrevocable undertakings from Hallin Shareholders as described in paragraph 6 above.
		As at the close of business on 10 December 2009, being the last practicable date prior to this announcement, neither Superior UK, nor any of the Superior UK Directors nor, so far as Superior UK is aware, any person acting in concert with Superior UK has: (i) any interest in or right to subscribe for any relevant securities of Hallin; (ii) any short positions in respect of relevant securities of Hallin (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 (iii) borrowed or lent any relevant security of Hallin (save for any borrowed securities which have been on-lent or sold).
		In view of the requirement for confidentiality, Superior UK has not made any enquiries in this respect of certain parties who may be deemed by the Takeover Panel to be acting in concert with it for the purposes of the Proposals.
15		Hallin Share Plan
		The Scheme will extend to any Hallin Shares that are unconditionally allotted or issued prior to the Scheme Record Time pursuant to the exercise of options or vesting of awards under the Hallin Share Plan.
		The Scheme will not extend to Hallin Shares unconditionally allotted or issued pursuant to the exercise of options or the vesting of awards under the Hallin Share Plan at or after the Scheme Record Time. At present options granted under the Hallin Share Plan which are not already exercisable do not become exercisable on a scheme of arrangement. An amendment is being proposed to the Hallin Share Plan to provide that options granted pursuant to the scheme are exercisable upon the approval by Hallin Shareholders of the Special Resolution. The proposed amendments will be set out in the Scheme Document.

		Participants will be invited to agree to the conditional exercise of their options prior to the Court Hearing, conditional only upon the Scheme being sanctioned by the Court.
		Appropriate proposals will be made to members of the Hallin Share Plan pursuant to Rule 15 of the Takeover Code at the same time as the Scheme Document is issued or as soon as possible thereafter. Details of these proposals will be set out in the Scheme Document and in separate letters to be sent to members of the Hallin Share Plan.
16		Delisting and re-registration
		Application will be made to the London Stock Exchange for the Hallin Shares to cease to be admitted to trading on AIM, to take effect immediately following the Effective Date. The date of cancellation is expected to be 27 January 2010.
		With effect from and including the Effective Date, share certificates in respect of the Hallin Shares will cease to be valid and should be destroyed. In addition, entitlements to Hallin Shares held within the CREST system will be cancelled on the Effective Date.
		As soon as possible after the Effective Date, it is intended that Hallin will be re-registered as a private limited company under the Isle of Man Companies Act 2006.
17		General
		The Acquisition will be subject to the conditions and further terms set out in this announcement and to the further terms to be set out in the Scheme Document. The Scheme Document will include full details of the Scheme, together with notices of the Court Meeting and the Hallin EGM.
		The Acquisition will be governed by Isle of Man law and be subject to the applicable requirements of the Takeover Code, the Takeover Panel, the London Stock Exchange and the Financial Services Authority.
		The implications of the Scheme for persons not resident in the UK or the Isle of Man may be affected by the laws of the relevant jurisdiction. Any persons who are subject to the laws of any jurisdiction other than the UK or the Isle of Man should inform themselves about and observe any applicable requirements.
		Superior UK reserves the absolute right to elect, subject to the prior consent of the Takeover Panel, to implement the Proposals by way of a takeover offer in accordance with the Takeover Code as it may determine in its absolute discretion. In such event, such offer will be implemented on the same terms (subject to appropriate amendments, including (without limitation) an acceptance condition set at 90 per cent. (or such lesser percentage (being more than 50 per cent.) as the Offeror may decide or the Takeover Panel may require) of the Hallin Shares to which such offer would relate), so far as applicable, as those which would apply to the Scheme. Furthermore, if sufficient acceptances of such offer are received and/or sufficient Hallin Shares are otherwise acquired, it is the intention of the Offeror to apply the provisions of section 154 of the Isle of Man Companies Act 1931 to acquire compulsorily any outstanding Hallin Shares to which any such offer relates.
		In accordance with Rule 19.11 of the Takeover Code, a copy of this announcement will be published on the following websites: www.hallinmarine.com and www.superiorenergy.com/.

Financial information included in this announcement for Hallin has been prepared, unless specifically stated otherwise, in accordance with accounting standards applicable in the UK and the Isle of Man and thus may not be comparable to the financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US. If the Offeror exercises its right to implement the acquisition by way of a takeover offer, the takeover offer will be made in compliance with applicable US laws and regulations.
		The receipt of cash pursuant to the Acquisition by a US holder of Hallin Shares as consideration for the transfer of its Hallin Shares pursuant to the Acquisition may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other tax

		laws. Each holder of Hallin Shares is urged to consult his independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him.
		It may be difficult for US holders of Hallin Shares to enforce their rights and claims arising out of US federal securities laws, since Hallin is not located in the United States, and some or all of their officers and directors may be residents of countries other than the United States. US holders of Hallin Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court’s judgement.
		Dealing disclosure requirements
		Under the provisions of Rule 8.3 of the Takeover Code, if any person is, or becomes, “interested” (directly or indirectly) in 1 per cent. or more of any class of “relevant securities” of Hallin, all “dealings” in any “relevant securities” of Hallin (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by no later than 3.30 p.m. (London time) on the Business Day following the date of the relevant transaction. This requirement will continue until the date on which the Proposals become effective, lapse or are otherwise withdrawn or on which the “offer period” otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest” in “relevant securities” of Hallin, they will be deemed to be a single person for the purpose of Rule 8.3.
		Under the provisions of Rule 8.1 of the Takeover Code, all “dealings” in “relevant securities” of Hallin by the Offeror or Hallin, or by any of their respective “associates”, must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.
		A disclosure table, giving details of the companies in whose “relevant securities” “dealings” should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel’s website at www.thetakeoverpanel.org.uk.
		“Interests in securities” arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in price of securities. In particular, a person will be treated as having an “interest” by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.
		Terms in quotation marks are defined in the Takeover Code, which can also be found on the Takeover Panel’s website. If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, you should consult the Takeover Panel.
		Forward-looking statements
		Certain statements in this announcement constitute forward-looking statements. The forward-looking statements contained herein include statements about the expected effects of the Proposals, the expected timing and scope of the Proposals and other statements other than in relation to historical facts. Forward-looking statements include, without limitation, statements typically containing words such as “intends”, “expects”, “anticipates”, “targets”, “estimates”, “believes”, “should”, “plans”, “will”, “expects” and similar expressions or statements that are not historical facts are intended to identify those expressions or statements as forward-looking statements. These statements are based on the current expectations of the Offeror and Hallin and are naturally subject to uncertainty and changes in circumstances. 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. There are a number of factors that could cause actual results and

developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, the satisfaction or waiver of the conditions to the Proposals, local and global political and economic conditions, the price of oil, gas and other hydrocarbons, foreign exchange rate fluctuations and interest rate fluctuations (including those from any potential credit rating decline) and legal or regulatory developments and changes. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements. Neither the Offeror nor Hallin, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur. Other than in accordance with their legal or regulatory obligations (including under the AIM Rules, the Disclosure and Transparency Rules of the Financial Services Authority and the Takeover Code), neither the Offeror nor Hallin is under any obligation and each of them expressly disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Subject to the requirements of the Takeover Panel, Superior UK reserves the right to waive in whole or in part all or any of the conditions in this Appendix I except those at paragraphs 1, 2 or 3(a). Superior UK shall be under no obligation to waive or treat as fulfilled any of conditions 3(a) to 3(h) inclusive by a date earlier than the date specified in paragraph 1 above for the fulfilment thereof notwithstanding that the other conditions of the Acquisition may at such earlier date have been waived or fulfilled and that there are at such earlier date no circumstances indicating that any of such conditions may not be capable of fulfilment.

5

The Acquisition will lapse and the Scheme will not proceed if the Acquisition or any part of it is referred by the Office of Fair Trading to the Competition Commission before the date of the Court Meeting.

6

The Proposals will be conditional upon the Scheme becoming unconditional and becoming effective by no later than 31 May 2010, or such date (if any) as Superior UK may, with the consent of the Takeover Panel, agree and (if required) the Court may approve.

7

If Superior UK is required by the Takeover Panel to make an offer for Hallin Shares under the provisions of Rule 9 of the Takeover Code, Superior UK may make such alterations to the terms and conditions of the Acquisition as are necessary to comply with the provisions of that Rule, provided that the terms of the offer are not less beneficial to the Hallin Shareholders.

8

Superior UK reserves the right to elect to implement the Acquisition by way of a takeover offer. In such event, such offer will be implemented on the same terms (subject to appropriate amendments, including (without limitation) an acceptance condition set at 90 per cent. (or such lesser percentage (being more than 50 per cent.) as Superior UK may decide or the Takeover Panel may require) of the shares to which the offer relates), so far as applicable, as those which would apply to the Scheme.

9

Hallin Shares will be acquired by Superior UK fully paid and free from all liens, rights to set-off, counterclaims, equitable interests, charges, encumbrances and other third party rights of any nature whatsoever and together with all rights attaching to them, including the right to receive and retain all dividends and distributions (if any) declared, made or payable after the date of this announcement.

10

The Acquisition will be on the terms and will be subject, amongst other things, to the conditions which are set out in paragraphs 1, 2 and 3 of this Appendix I and those terms which will be set out in the Scheme Document and accompanying Forms of Proxy and such further terms as may be required to comply with the AIM Rules, the provisions of the Takeover Code and the provisions of the Isle of Man Companies Acts 1931 to 2004. The Scheme will be governed by the laws of the Isle of Man.

11

The availability of the Proposals to persons not resident in the United Kingdom or the Isle of Man may be affected by the laws of the relevant jurisdictions. Persons who are not resident in the United Kingdom or the Isle of Man should inform themselves about and observe any applicable requirement.

Superior Energy Services, Inc. Announces Agreement to Acquire
Singapore-Based Hallin Marine Subsea International Plc
Transaction enhances Superior’s position in international subsea services markets

New Orleans, La., December 11, 2009 – Superior Energy Services, Inc. (NYSE: SPN) (“Superior” or the “Company”) today announced that it has entered into an Implementation Agreement with Hallin Marine Subsea International Plc (AIM: HMS) (“Hallin”), to acquire Hallin for a price of 233 pence in cash per Hallin share (the “Offer”). The Offer values Hallin’s existing issued and to be issued fully diluted ordinary share capital at approximately 103.5 million pounds sterling (approximately $168.3 million based upon an exchange rate of US$1.626, at the close of business on December 10, 2009). Hallin is an international provider of integrated subsea services and engineering solutions, focused on installing, maintaining and extending subsea wells. Hallin operates in most international offshore oil and gas markets with major offices and facilities located in Singapore, Jakarta, Indonesia; Perth, Australia; Aberdeen, Scotland; and Houston, Texas. For more information on Hallin, visit its website at www.hallinmarine.com.

Hallin offers Superior the opportunity to enhance its position in the emerging subsea well intervention market through the combination of Superior’s well intervention assets and Hallin’s existing subsea assets (remotely operated vehicles, saturation diving systems and chartered vessels) and newbuild vessel program.

Terence Hall, Chairman and CEO of Superior, stated, “In the short-run, this transaction will provide us with more international penetration and expanded entry into the subsea field development and installation market. Going forward, we believe the combination of Hallin’s experienced management team, existing global infrastructure and Superior’s well intervention experience and integrated solutions approach will serve as a strong platform for expansion into the growing subsea well intervention market worldwide.”

Superior intends to fund the acquisition through its existing revolving credit facility. In the event the conditions to the Offer are satisfied and/or waived by the parties, the transaction is expected to close in the first quarter of 2010.

The Offer is to be effected by way of a scheme of arrangement under section 152 of the Isle of Man Companies Act 1931, as amended. Copies of the Offer-related documentation including a copy of the announcement which was made pursuant to Rule 2.5 of the City Code on Takeovers and Mergers (the “Rule 2.5 Announcement”) is available to the public, subject to restrictions relating to persons in certain overseas jurisdictions, at www.superiorenergy.com. It is anticipated that the scheme document (the “Scheme Document”) will be posted to Hallin’s shareholders on December 12, 2009 and a copy of this document will also be available at this website.

Superior Energy Services, Inc. serves the drilling and production needs of oil and gas companies worldwide through its brand name rental tools and its integrated well intervention services and tools, supported by an engineering staff who plan and design solutions for customers. Offshore projects are delivered by the Company’s fleet of modern marine assets.
