PARTIAL CASH AND SHARES OFFER

for

Rock Solid Images Plc ("RSI")

by

Thalassa Holdings Ltd ("Thalassa")

Summary

·; Thalassa is pleased to announce that it will be making a partial cash offer, with the Thalassa Shares Alternative, to RSI Shareholders pursuant to which Thalassa will offer to acquire up to 40,952,521 RSI Shares, representing approximately 25.89 per cent. of the entire issued ordinary share capital of RSI (the "Partial Offer"). Following the Partial Offer, if the Thalassa Shares Alternative is accepted in full, Thalassa, together with its existing shareholding of 6,342,322 RSI Shares, will hold 47,295,496 RSI Shares, representing approximately 29.90 per cent. of the entire issued ordinary share capital of RSI.

·; Under the terms of the Partial Offer, which will be subject to the Conditions and further terms set out in Appendix I to this announcement and to be set out in the Offer Document, Qualifying RSI Shareholders will be entitled to receive:

for each RSI Share acquired in the Partial Offer 0.48 pence in cash (the "Cash Offer") or, at the election of RSI Shareholders, 1 New Thalassa Share for every 43 RSI Shares held (the "Thalassa Shares Alternative").

·; The value of the Thalassa Shares Alternative is a 50% premium to the value of the Cash Offer, based on the closing price of Thalassa Shares on 29 March 2012.

·; Thalassa and RSI both operate in the seismic industry; Thalassa is involved in obtaining seismic data and RSI in interpreting seismic data. The Thalassa board wish to explore opportunities for the two firms to collaborate in offering their combined services to the existing customer bases.

·; Thalassa considers the Partial Offer to be the best way available to it to provide strategic support to RSI through an increased shareholding which Thalassa hopes will strengthen RSI's competitive position and demonstrate Thalassa's long term commitment to RSI.

·; With RSI Shareholders effectively being faced with no ability to realise their investment once RSI's AIM quotation is terminated, Thalassa believes that the Thalassa Shares Alternative delivers continued participation in an AIM quoted company operating in the same sector with a substantial minority stake in RSI.

·; In the event that RSI Shareholders elect to take the Thalassa Shares Alternative in full, they would in aggregate hold approximately 7.5% of the enlarged issued share capital of Thalassa.

·; The Cash Offer of 0.48 pence is based on the weighted average Closing Price of RSI Shares from the 12 March 2012 (being the date on which RSI announced its intention to terminate its AIM quotation) to 29 March 2012 (the last practicable day prior to the announcement of this Partial Offer) and values the RSI Shares subject to the Partial Offer at approximately £197,832. The Cash Offer represents:

● a premium of 28.4 per cent. to 0.38pence, being the weighted average Closing Price for RSI Shares in the period between 12 March 2012 (being the day RSI indicated its intention to seek the cancellation of its AIM admission) and 26 March 2012, being the day before Thalassa declared its initial stake in RSI.

● a discount of 51.7 per cent. to 1.0 pence, being the Closing Price on 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period);

● a discount of 49.3 per cent. to 0.95 pence, being the weighted average Closing Price over the three months from 29 December 2011 to 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period); and

● a discount of 91.9 per cent. to 6.0 pence, being the Closing Price on 4 April 2011 (being the highest Closing Price during the 52 weeks prior to the commencement of the Offer Period).

·; The Thalassa Shares Alternative is based on the closing price of Thalassa Shares on 29 March 2012 (the last practicable day prior to the announcement of this Partial Offer) and 0.72 pence for the RSI Shares, being a 50% premium to the Cash Offer, and values the RSI Shares subject to the Partial Offer at approximately £296,749. The Thalassa Shares Alternative represents:

● a discount of 27.5 per cent. to 1.0 pence, being the Closing Price on 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period);

● a discount of 23.9 per cent. to 0.95 pence, being the weighted average Closing Price over the three months from 29 December 2011 to 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period); and

● a discount of 87.9 per cent. to 6.0 pence, being the Closing Price on 4 April 2011 (being the highest Closing Price during the 52 weeks prior to the commencement of the Offer Period).

·; To the extent that Qualifying RSI Shareholders accept the Cash Offer and/or the Thalassa Shares Alternative in excess of 40,952,521 RSI Shares, being the total amount of RSI Shares that Thalassa can acquire under the Partial Offer, then all acceptances of the Partial Offer shall be scaled back pro-rata.

·; Thalassa is a holding company, quoted on AIM, which through its subsidiaries focuses on marine seismic operations; assisting in the discovery of new oil reserves and maximising oil recovery through reservoir management practices. Long term growth prospects for the enlarged Thalassa Group remain encouraging with record inquiries and a number of potential long term contracts.

·; RSI is an independent industry leader in the quantitative interpretation and integration of seismic data with well-log, CSEM and MT data. RSI uses advanced rock physics methods combined with sophisticated geologic models, microseismic and production data to deliver robust and reliable predictions of reservoir geometries and properties to RSI's clients. RSI is currently quoted on AIM. 

·; Thalassa is making the Partial Offer without it being recommended by the RSI Directors as RSI is due to seek Cancellation from AIM on 13 April 2012, with the last day of trading on the RSI Shares being 12 April 2012. Accordingly, Thalassa believes that announcing the Partial Offer before 12 April 2012 will give RSI Shareholders an alternative exit strategy and an ability to retain AIM listed shares whilst continuing to have some exposure to the underlying RSI business.

·; The Partial Offer is conditional upon, inter alia, valid acceptances being received (and not, where permitted, withdrawn) in respect of not less than 18,966,304 RSI Shares (equivalent to 16% of the entire issued share capital of RSI including the existing holding of Thalassa).

·; The Partial Offer is subject to further conditions set out in Appendix I. Appendix I also sets out certain further terms of the Partial Offer, with the full terms to be set out in the Offer Document.

·; Once the Offer Document has been published, RSI Shareholders shall have a minimum period of 28 days to accept the Partial Offer.

Daniel Stewart, which is authorised and regulated in the United Kingdom by the Financial Services Authority, is acting as financial adviser to TH and no one else in connection with the matters set out in this document and will not be responsible to anyone other than Thalassa for providing the protections afforded to clients of Daniel Stewart, nor for providing advice in relation to any matter referred to herein.

PARTIAL CASH AND SHARES OFFER

for

Rock Solid Images Plc ("RSI")

by

Thalassa Holdings Ltd ("Thalassa")

1. Introduction

Thalassa is pleased to announce that it will be making a partial cash offer, with the Thalassa Shares Alternative, to RSI Shareholders pursuant to which Thalassa will offer to acquire up to 40,952,521 RSI Shares, representing approximately 25.89 per cent. of the entire issued ordinary share capital of RSI (the "Partial Offer"). Following the Partial Offer, if the Thalassa Shares Alternative is accepted in full, Thalassa together with its existing shareholding of 6,342,322 RSI Shares, will hold 47,295,496 RSI Shares, representing approximately 29.90 per cent. of the entire issued ordinary share capital of RSI.

2. The Partial Offer

Under the terms of the Partial Offer, which will be subject to the Conditions and further terms set out in Appendix I to this announcement and to be set out in the Offer Document, Qualifying RSI Shareholders will be entitled to receive:

for each RSI Share acquired in the Partial Offer 0.48 pence in cash (the "Cash Offer") or, at the election of RSI Shareholders, 1 New Thalassa Share for every 43 RSI Shares held (the "Thalassa Shares Alternative").

·; the Cash Offer of 0.48 pence is based on the weighted average mid-market Closing Price of RSI Shares from the 12 March 2012 (being the date on which RSI announced its intention to terminate its AIM quotation) to 29 March 2012 (the practicable day prior to the announcement of this Partial Offer) and values the RSI Shares subject to the Partial Offer at approximately £197,832. The Cash Offer represents:

·; a premium of 28.4 per cent. to 0.38pence, being the weighted average Closing Price in the period between 12 March 2012 (being the day RSI indicated its intention to seek the cancellation of its AIM Admission) and 26 March 2012, being the day before Thalassa declared its initial stake in RSI.

● a discount of 51.7 per cent. to 1.0 pence, being the Closing Price on 26 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period);

● a discount of 49.3 per cent. to 0.95 pence, being the weighted average Closing Price over the three months from 29 December 2011 to 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period); and

● a discount of 91.9 per cent. to 6.0 pence, being the Closing Price on 4 April 2011 (being the highest Closing Price during the 52 weeks prior to the commencement of the Offer Period).

·; The Thalassa Shares Alternative is based on the weighted average closing price of Thalassa Shares on 29 March 2012 (the day prior to the announcement of this Partial Offer) and values the RSI Shares subject to the Partial Offer at approximately £296,749. The Thalassa Shares Alternative represents:

● a discount of 27.5 per cent. to 1.0 pence, being the Closing Price on 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period);

● a discount of 23.9 per cent. to 0.95 pence, being the weighted average Closing Price over the three months from 29 December 2011 to 29 March 2012 (being the last practicable Business Day prior to the commencement of the Offer Period); and

● a discount of 87.9 per cent. to 6.0 pence, being the Closing Price on 4 April 2011 (being the highest Closing Price during the 52 weeks prior to the commencement of the Offer Period)..

The value of the Thalassa Shares Alternative is a 50% premium to the value of the Cash Offer, based on the closing price of Thalassa Shares on 29 March 2012, the last practicable day prior to the announcement of this Partial Offer.

To the extent that Qualifying RSI Shareholders accept the Cash Offer and/or the Thalassa Shares Alternative in excess of 40,952,521 RSI Shares, being the total amount of RSI Shares that Thalassa can acquire under the Partial Offer, then all acceptances of the Partial Offer shall be scaled back pro-rata.

The Partial Offer is subject to satisfaction of certain conditions, including, inter alia valid acceptances being received (and not, where permitted, withdrawn) in respect of not less than 18,966,304 RSI Shares representing 11.99 per cent. of RSI's issued share capital.

If the acceptance of the Partial Offer referred to above is not obtained, the Partial Offer will lapse. 

Instructions for RSI Shareholders as to how to approve the Partial Offer (whether or not they wish to accept the Partial Offer) will be set out in the Offer Document.

All RSI Shareholders holding RSI Shares in certificated form who wish to accept the Partial Offer should complete, sign and return the Form of Acceptance (which will be sent to them together with the Offer Document) as soon as possible and in accordance with the procedures set out in the Offer Document.

All RSI Shareholders holding RSI Shares in uncertificated form who wish to accept the Partial Offer should make their acceptances electronically through CREST. RSI Shareholders who are not CREST members should notify their CREST member brokerage firms of which they are clients of their decision to accept the Partial Offer.

Important note to option holders

Holders of options over RSI Shares that are exercisable (or will become exercisable during the period in which the Partial Offer is open for acceptance) are informed that they may exercise their options and participate in the Partial Offer on the same terms as RSI Shareholders provided that the RSI Shares that result from option exercise are registered on the register of members by the Record Date.

3. Background to and reasons for the Partial Offer

Thalassa has considered the business of RSI and believes that there is potential for interesting synergies and opportunities in the event that the two businesses were to be operated under a collaborative methodology for marketing and development purposes.

In addition, RSI Shareholders are effectively faced with no ability to realise their investment once RSI's AIM quotation is terminated. Matched bargain facilities of the nature proposed by RSI rarely deliver any fair value for minority shareholders.

Thalassa believes that the Partial Offer delivers a real liquidity prospect for RSI Shareholders, giving them the alternative of a cash exit or continued participation in a growing AIM quoted company operating in the same sector, with a substantial minority stake in RSI. The Thalassa Share Alternative has the ability to deliver RSI Shareholders liquidity and continued participation in the RSI business.

The Thalassa Directors felt that an offer to acquire more than 50% of the voting rights in RSI was unlikely to be successful as Thalassa would need to have acquired or agreed to acquire RSI Shares carrying at least 50% of the voting rights of RSI. Similarly, any partial offer for shares in RSI carrying between 30% and 50% of the voting rights in RSI also requires a 50% acceptance condition. Given the annual shareholder base of RSI, Thalassa believes that such approval is unlikely to be forthcoming, which is why Thalassa considers the Partial Offer to be the best offer route available to it.

4. Information on Thalassa

Thalassa was incorporated and registered in the British Virgin Islands ("BVI") on 26 September 2007. Thalassa currently has two subsidiaries, WGP Exploration Ltd ("WGP") and WGP Energy Services Ltd ("WESL").

WESL (formerly called Thalassa Energy Services) was established to acquire marine seismic equipment, specifically a 'Portable Modular Source System' ("PMSS"). The equipment can be installed on a vessel in order to provide the seismic (sound) source to allow exploration and production companies to perform reservoir monitoring. WGP was acquired by the Thalassa Group on 16 November 2011.

WGP delivers a wide range of technologies and services throughout the global upstream oil and gas industry, including a range of unique seismic acquisition services with over 20 years of operational and management experience

WESL's PMSS units and WGP's operational experience assists oil companies in maximising oil recovery through reservoir management practices as well as assisting in the discovery of new reserves.

Current Trading and Prospects

Thalassa Group's results for the year to 31 December 2011 show revenue of US$2,427,985, an increase of 501% compared to 2010 (2010: US$404,086). Operating profit (EBIT) was US$344,712, an increase of US$ 535,463 from a loss in 2010 of US$ (190,751). Profit for the financial period was US$355,675, a decrease of 34.9% over the prior period (2010: US$ 546,259) which included investment income of US$ 646,441. All financial investing activity ceased at the end of 2010. On a comparable basis, excluding the income from financial investments, 2011 saw an increase in net profit of US$455,857 from an adjusted loss in the prior period of US$(100,182).

The Directors believe that increasing global demand for oil will drive exploration in increasingly remote locations and challenging environments. At the same time, there will be greater pressure to maximize extraction from existing fields. The corporate strategy for the enlarged Group is "Exploration and Beyond". "Exploration" is focused on activity in frontier and challenging locations (e.g. Artic, Central African Lake Systems), whilst "Beyond" focuses on production activity by looking to aggressively secure opportunities in the PRM market. Thus activity and focus will be dominated by projects in remote and challenging frontier locations, coupled with lower risk projects in mature producing regions.

Long term growth prospects for the enlarged Thalassa Group remain encouraging with record inquiries and a number of potential long term contracts.

The nature of Thalassa Group's business is based on a small number of large contracts, each of which has the potential to significantly affect the Thalassa Group's results for the year. At the current time the Thalassa Group has around US$2.6m of contracted revenue for 2012 and is in discussions on several significant opportunities for the year.

5. Information on RSI

RSI is an independent industry leader in the quantitative interpretation and integration of seismic data with well-log, CSEM and MT data. RSI uses advanced rock physics methods combined with sophisticated geologic models, microseismic and production data to deliver robust and reliable predictions of reservoir geometries and properties to RSI's clients.

The cost of sales in the year to 31 August 2011 was £2.4 million which was very similar to 2010 (£2.4 million). The resulting gross profit from operations in 2011 was £1.6 million (41% of revenues) compared to a gross profit of £1.2 million (34% of revenues) in 2010. The year to 31 August 2011 saw a reduced loss of £2.4 million from that reported in the previous year (2010: £17.1 million loss). At the period end the RSI Group had cash on hand of £1.7 million and no third party borrowings. This compares with a bank balance of £3.4 million at the end of August 2010 (also no third party borrowings).

Current Trading and Prospects

Since 18 January 2012, when RSI reported its results for the 12 months ending 31 August 2011, sales and revenues in January and February were less than anticipated due to operational delays in processing client data. Revenues in the second half of 2012 are anticipated to be significantly above those of the first half of 2012. Total revenues for the full year to 31 August 2012 are expected to be in the £5.5 to £7 million range, which compares with revenues of £4 million for the year ended 31 August 2011.

On 4 April 2012, RSI announced its intention to submit for its cancellation from AIM (the "RSI Cancellation"). The RSI Directors expect that the low valuation of the RSI Shares on AIM and liquidity will continue to impact directly and negatively on the Company's ability to raise adequate equity and debt financing based on appropriate valuations, and this could potentially damage the medium and long term interests and objectives of RSI. The RSI general meeting to approve the RSI Cancellation is due to take place on 4 April 2012, with the cancellation of the RSI Shares to trading on AIM effective on 13 April 2012.

The full details may also be found on the RSI's website at: (http://www.rocksolidimages.com/pdf/constitutionaldocs/2012_04_04_GM_Notice.pdf) and (http://www.rocksolidimages.com/pdf/2012_03_12_De-listing.pdf)

6. Directors, management, employees and locations

Thalassa confirms, in accordance with the provisions of the Code, that following the Partial Offer becoming or being declared unconditional in all respects, Thalassa has no intention of proposing any changes to the board of RSI or the existing employment rights of management and employees of RSI. These matters shall continue to be managed by the board of RSI.

7. Financing

Thalassa is providing the cash consideration payable under the Partial Offer from its own resources.

Daniel Stewart, financial adviser to Thalassa, is satisfied that sufficient resources are available to satisfy in full the cash consideration payable to Qualifying RSI Shareholders under the terms of the Partial Offer.

8. Terms of Thalassa Share Alternative

RSI Shareholders (other than certain Overseas Shareholders) will be entitled to elect to receive New Thalassa Shares in respect of part or all their holdings of RSI Shares at an exchange ratio 1 New Thalassa Share for every 43 RSI Shares held. No fractions of Thalassa Shares will be issued. Accordingly an RSI Shareholder holding less than 43 RSI Shares will not be capable of electing to take the Thalassa Share Alternative.

The Thalassa Shares Alternative is based on the closing price of Thalassa Shares on 29 March 2012 (the last practicable day prior to the announcement of this Partial Offer) and 0.72 pence for the RSI Shares, being a 50% premium to the Cash Offer, and values the RSI Shares subject to the Partial Offer at approximately £296,749.

9. Opening Position Disclosures and Interests

Thalassa confirms that it will make an Opening Position Disclosure shortly following the date of this announcement, setting out the details required to be disclosed by it under Rule 8.1(a) of the Code.

10. Offer Document

It is expected that the Offer Document and the Form of Acceptance accompanying the Offer Document will be published as soon as practicable and, in any event, (save with the consent of the Panel) within 28 days of this announcement. The Offer Document and Form of Acceptance will be made available to all RSI Shareholders at no charge to them.

Once the Offer Document has been published, RSI Shareholders shall have a minimum period of 28 days to accept the Partial Offer.

RSI Shareholders are urged to read the Offer Document and the accompanying Form of Acceptance when they are sent to them because they will contain important information.
