AVISEN PLC

1.             IntroductionThe boards of 1Spatial and Avisen are pleased to announce that they have agreed terms of a merger whereby the entire share capital of 1Spatial would be acquired by Avisen in consideration for the issue of 5.761 New Avisen Shares for each 1Spatial Share.  The Proposal is to be implemented by means of a Scheme of Arrangement under the Act, which requires the approval of 1Spatial Shareholders and the sanction of the Scheme and confirmation of the Reduction of Capital by the Court. On completion, the Enlarged Group will transition to a single 1Spatial brand.

2.             Terms of the Scheme Offer

It is intended that the Scheme Offer will be implemented by means of a Court-sanctioned Scheme of Arrangement pursuant to Part 26 of the Act involving a reduction of capital of 1Spatial under the Act.  The Scheme is subject to the satisfaction (or, where applicable, waiver) of the Conditions and sanction of the Court. 

The Scheme provides that, if it becomes effective, all of the existing 1Spatial Shares will be cancelled under the Reduction of Capital and a like number of New 1Spatial Shares will be issued, fully paid, to Avisen.  The reserve arising from the cancellation of the existing 1Spatial Shares will be used in paying up in full such New 1Spatial Shares.  In exchange, under the Proposal, all 1Spatial Shareholders will be entitled to receive:

For each 1Spatial Share: 5.761 fully paid New Avisen Shares

1Spatial will become a wholly owned subsidiary of Avisen on the Effective Date.  Avisen is a public company incorporated in England and Wales, and its shares are admitted to trading on AIM.

The Proposal values the entire issued share capital of 1Spatial at approximately £4.74million and each 1Spatial Share at 22.35 pence (based on the Closing Price of 3.88 pence per Avisen Share on 6 October 2011, the last Business Day prior to this Announcement).

Entitlements to New Avisen Shares will be rounded down to the nearest whole number of Avisen Shares.  Fractions of New Avisen Shares will not be allotted or issued to 1Spatial Shareholders.  Fractional entitlements of New Avisen Shares will be aggregated and sold in the market and the net cash proceeds of the sale retained for the benefit of Avisen.

1Spatial Shareholders should note that the value of the Consideration that they will ultimately receive (once the Scheme is implemented and becomes effective in accordance with its terms) will depend upon the market value of New Avisen Shares received by them on the settlement date, and this value may vary.

The New Avisen Shares will be issued credited as fully paid, on identical terms to and will rank pari passu with the Avisen Shares in issue on the date on which the New Avisen Shares are issued, including the right to receive and retain all dividends, distributions or entitlements declared, paid or made after the Scheme becomes effective.

Application will be made to the London Stock Exchange for the New Avisen Shares to be admitted to trading on AIM following the Scheme becoming effective.  Upon the scheme becoming effective, 1Spatial's shares will be cancelled and therefore no longer be admitted to trading on AIM.

If the Scheme becomes effective, 1Spatial will become a wholly owned subsidiary of Avisen on the Effective Date and the 1Spatial Shareholders will receive the Consideration referred to above.

Scheme becoming effective

The Scheme requires the approval of a majority in number of the 1Spatial Shareholders representing at least seventy-five per cent in nominal value of the 1Spatial Shares present and voting (either in person or by proxy) at the Court Meeting (voting at which shall be conducted by way of a poll).  In addition, the Reduction of Capital will require the approval of 1Spatial Shareholders at the General Meeting.

If the Scheme becomes effective, it will be binding on all 1Spatial Shareholders, irrespective of whether or not they attended or voted at the Court Meeting or the General Meeting. 

Avisen intends to make an application to the London Stock Exchange for admission to trading on AIM of its New Avisen Shares. Upon the scheme becoming effective, 1Spatial's shares will no longer be admitted to trading on AIM.

Interests in the Enlarged Group

Following the Scheme becoming effective, existing Avisen Shareholders will hold 226,699,878 Avisen Shares representing approximately 65.0 per cent of the Enlarged Issued Share Capital of Avisen and existing 1Spatial Shareholders will hold approximately 122,069,402 Avisen Shares representing approximately 35.0 per cent of the Enlarged Issued Share Capital of Avisen.

3.             Recommendation

The Independent 1Spatial Directors who have been advised by Libertas, consider the terms of the Proposal to be fair and reasonable and this is why they unanimously intend to recommend that 1Spatial Shareholdersvote in favour of the Resolutions to give effect to the Proposal, as the Independent 1Spatial Directors have irrevocably undertaken to do in respect of their beneficial holdings of 12,299,725 1Spatial Shares representing approximately 58.0 per cent of the existing issued ordinary share capital of 1Spatial.  In providing its advice to the 1Spatial Board, Libertas has taken into account the commercial assessments of the Independent 1Spatial Directors.

In order to approve the terms of the Proposal, Scheme Shareholders will need to vote in favour of the Resolution to be proposed at the Court Meeting and 1Spatial Shareholders will need to vote in favour of the Resolutions to be proposed at the General Meeting to be held on 7 November 2011.  The unanimous recommendation of the Independent 1Spatial Directors and advice to 1Spatial Shareholders is set out in paragraph 5 of this Announcement.

Marcus Hanke is a non-executive director of 1Spatial and is also an executive director of Avisen. As a result, Marcus Hanke has not participated in the consideration by the 1Spatial Board as to whether the Proposal is fair and reasonable, nor the decision to recommend the Proposal. Marcus Hanke owns or is interested in 32,690 1Spatial Shares representing approximately 0.15 per cent. of the 1Spatial Shares in issue and owns or is interested in 29,026,314 Avisen Shares representing approximately 12.8 per cent. of the Avisen Shares in issue. The Independent 1Spatial Directors do not have any interest in any Avisen Shares.

Statements made or referred to in this Announcement concerning Avisen's reasons for the Proposal and to the intentions and expectations of Avisen and its subsidiaries reflect the views of the Avisen Board.  Statements made or referred to in this Announcement concerning the background to and reasons for the Independent 1Spatial Directors recommending the Proposal reflect the views of the 1Spatial Board.

4.             Background to and reasons for the Proposal

On 19 October 2010, 1Spatial was admitted to trading on AIM by way of a reverse acquisition of IQ Holdings plc.  The reasons for this transaction were three-fold:

(i)         to enable 1Spatial to raise capital by way of investment in shares in the listed company,  which supported further investment in technology development and marketing; (ii)        to enable 1Spatial to raise capital by way of investment in shares in the listed company in order to support geographic expansion by way of acquisition; and(iii)       to strengthen the business acumen of the company by attracting independent advisors and investors.

Since the completion of the listing, 1Spatial has achieved a series of key milestones:

·      completed an acquisition in Australia to exploit the growing demand for high quality spatial data to support environmental management and economic development

·      completed the delivery of the landmark data management solution to Ordnance Survey Great Britain (OSGB)

·      secured long term, high value contracts with Ordnance Survey Ireland for data re-engineering and enhancement and with OSGB to support the automation of their product generation capability

·      restructured the company to factor in all exceptional costs and maximise future profitability

As a result, 1Spatial is now positioned for growth, which will be best achieved through further investment in its rule-engine. 1Spatial's rule-based approach to spatial data processing is gaining increasing acceptance in the marketplace.  To exploit this, 1Spatial has structured the company to focus on three markets:

(i)         itscore market: the National topographic mapping and cadastral agencies, who require enterprise solutions for nationwide data management.  1Spatial is branding this offering as Imperium, which now requires investment to productise and exploit its market advantage;(ii)        the GIS market, where 1Spatial continues to strengthen strategic relationships with the major players in this sector, who are interested in integrating 1Spatial'srules engine and geo-processing components as the public data transparency initiatives lead to the development of new knowledge based applications;and (iii)       the data quality market which is being addressed with a new Software as a Service offering, marketing under a new brand, Socium.

In addition, 1Spatial's Board of Directors believes that the wider analytics Business Intelligence marketplace provides an opportunity to extend the spatial data supply chain into location enabled decision-making.

Avisen operates through two businesses with the common focus of enhancing client profitability. Its business and technology consultancy, Avisen, specialises in Performance Management, with a focus on strategy creation, development and implementation through business advisory services and distribution and implementation of Acorn Systems software solutions. Storage Fusion develops and sells Storage Resource Analysis Software.

Avisen was admitted to trading on AIM on 2 February 2009 following its reverse takeover of Z Group plc.  Since its admission, Avisen has pursued an acquisition strategy in the Corporate Performance Management market and to date has completed six acquisitions.

The Avisen management team has demonstrated its ability to rapidly absorb the new businesses in order to achieve cost savings and to grow the recurring income base of the Avisen Group through software and solution support.

Avisen now provides advisory services and software distribution to a growing number of blue chip corporations and examples include: Tesco Direct and Unilever.

The boards of Avisen and 1Spatial believe that Avisen's acquisition of 1Spatial will allow the Enlarged Group to:

·              establish a more experienced management team with a broader skill set through the appointment of Nic Snape, Dr. Mike Sanderson and Steve Berry to the Avisen Board.  This will further enhance the Enlarged Group's ability to identify future opportunities to enhance shareholder value;

·              accelerate the investment in 1Spatial's Imperium, GIS Market Strategic Relationships and Avisen's new brand, Socium;

·              utilise the cash resources of Avisen in order to accelerate the growth of the Enlarged Group, both organically and by further acquisitions in the business and technology sectors;

·              extend the location supply chain capability, to offer location enabled decision making to the Business Intelligence market; and

·              optimise the Storage Fusion Business as part of Avisen's existing performance management services.

Further information on Avisen and the strategy for the Enlarged Group will beset out in the Scheme Document.

5.             Background to and reasons for recommending the Proposal

The Independent 1Spatial Directors have considered the terms of the Proposal and unanimously recommend that 1Spatial Shareholders vote in favour of the Resolutions to be proposed at the Meetings.

The Independent 1Spatial Directors have therefore advised that each 1Spatial Shareholder should consider carefully the information set out below in making a decision as to whether to approve the Proposal.  This is not intended to be an exhaustive list of relevant factors and 1Spatial Shareholders should consider their individual circumstances carefully before deciding whether to vote in favour of the Resolutions to be proposed at the Meetings.

Effects of Proposal

·              The Proposal represents a discount of 10.6 per cent to the Closing Price of 25 pence per 1Spatial Share on 6 October 2011, the last Business Day prior to this Announcement based on a Closing Price for Avisen Shares of 3.88 pence on 6 October 2011; and

·              The Proposal represents a premium of 17.3 per cent to the Closing Price of 25 pence per 1Spatial Share on 6 October 2011based on the average Closing Price for Avisen Shares of 5.09 pence over the three month period ended on and including 6 October 2011.

Additional reasons for recommending the Proposal:

·              Avisen has significant cash reserves which provide funds to accelerate investment in technology development in order to exploit the market position that 1Spatial hasachieved;

·              Avisen has an established blue chip client list in the commercial sector. Avisen's contracts with Tesco Direct and Unilever provide a solid foundation for the market introduction of location enabled analytics business models;and

·              Avisen's Directors would bring significant experience into 1Spatial's strategic planning, in particular expertise in digital media, which would have significant benefit to the development of 1Spatial's new brand, Socium.

The 1Spatial Board believe that the merged entity would have a significantly enhanced market capitalisation and would provide a more interesting vehicle to attract investment.  The size of the combined company would be more attractive to the banking sector and have more credibility when pursuing larger system integration opportunities in 1Spatial'score market. All of these factors will provide the Enlarged Group with a significant platform from which to grow.

6.             Information on 1Spatial

Corporate History

1Spatial was originally called Laser-Scan and was formed in 1969 as an offshoot from the Cavendish Laboratory at Cambridge University initially developing laser-tracking devices and progressing, in 1975, to technologies that support mapping.  In 1979 a contract with Ordnance Survey Great Britain (OSGB) was secured to build a national mapping database. Over the next 10 years, 1Spatial focussed on the digital mapping sector, securing sales around the world.

In 2000 Laser-Scan was purchased by the Yeoman Group plc, which was developing a new offering of in-car navigation services via mobile phone.  Laser-Scan technology was used to build the advanced spatial database that supported accurate navigation routing.  In 2001, new management were appointed and major investments were made in the development of components that extended Oracle's mainstream database technology, giving users the ability to enhance and maintain the quality of their spatial data. 

In June 2003, the new management team established 1Spatial as a new company in order to complete a management buy-out of the goodwill and certain assets of Laser-Scan, which had been placed into administration. 1Spatial became an independent company focussed on automating the management of spatial data quality. The company won a number of key contracts with the RAF, a consortium of German states, Northern Ireland's Mapping Agency and Land Registry Ireland, which gave the company a solid recurring revenue base and re-established its reputation. A growth strategy followed, with 1Spatial making a number of successful acquisitions.  These strategic acquisitions provided additional technology capability and additional revenue from solid installed bases that remain today. They were as follows:

·      Sysdeco Kongsberg AS, Norway                          November 2004

·      IME UK Limited, Stirling, Scotland                      June 2007

·      Proteus Solutions Limited, Cork, Ireland             July 2007

·      Comsine Limited, Hampshire                            June 2008

Having established a sound commercial base, 1Spatial embarked on significant technology developments.  1Spatial's object-oriented data cache was integrated into a mainstream web-service architecture which provided a new approach to capturing knowledge through the use of an open rules language.  This new approach to spatial data validation, enrichment and optimisation enabled 1Spatial to win a landmark contract with OSGB.  This offering is marketed under the 1Spatial brand name Radius Studio.

The OSGB project success has had a significant impact on the profile of 1Spatial.  Many other mapping agencies are interested in the architecture and technology. Code delivery sign off occurred at the end of 2010. At the same time 1Spatial was awarded a contract by OSGB to provide technology to support automated map production based on 1Spatial's map generalisation, or simplification, technology.  Radius Studio is also being used by other National Mapping agencies such as, the Royal Airforce Charting Unit, Land Information New Zealand, Land and Property Services Northern Ireland, Ordnance Survey Ireland, Swedish Maritime Administration, IGN Belgium, German Lande and PSMA Australia.

Following the completion of the reverse acquisition of IQ Holdings in October 2010 and the subsequent listing on AIM, 1Spatial has begun the process of exploiting its platform through expansion internationally and domestically.  Lagen Spatial pty Limited was acquired in April 2011 to strengthen capacity in Asia Pacific and take advantage of the significant opportunity in Australia.

Current Trading and Prospects

1Spatial has just completed its eighth year of trading since the management buyout in 2003. It was a disappointing year financially, with revenues falling to £7.311 million for the year ended 30 June 2011. This was largely due to significant delays in signing large contracts and the cancellation of planned investments by other customers. The impact of these was to shift £1 million of expected revenue into the future. OSGB and OS Ireland have now been secured, which provides good revenues for visibility for the 2012 financial year. Profitability and asset value were also impacted by the reverse acquisition, with exceptional costs in excess of £2 million being accounted for in the last financial year. 1Spatial is now structured to focus on three clear markets, with different business models and significant prospects for growth and increased profitability:

·      Data Providers. The solution delivered to OSGB for data management and automated generalisation, is being marketed under the brand name Imperium.  This is targeted at the National topographic mapping and cadastral agencies.

·      GIS Market.  The success of 1Spatial's rules engine and approach to spatial data integrity and processing has captured the attention of the major players in the GIS Sector.  This is a £1.5 billion annual market. 1Spatial's focus is to continue to strengthen its strategic relationships with leading companies in that sector by developing components that integrate its rules engine and geo-processing technology into solutions provided by key companies, who represent over half of the total annual market with a combined customer base of 100,000s.

·      SoftwareasaService.  The scalable, web services architecture of Radius Studio has enabled 1Spatialto launch a new company, offering spatial data quality improvement under a Software as a Service Business Model.  This will give access to 1Spatial'ssophisticated technology via a simple, 4 button web based application.  This will open up its technology to a market of nearly 200,000 potential customers.

The 1Spatial Directors believe that by securing access to the cash reserves of Avisen through the merger and enabling 1Spatial's technology to be productised at an accelerated rate, 1Spatial will be in a better position to realise these potential prospects.

7.             Information on Avisen

Avisen is a management consultancy and software business that provides companies with advice and solutions in order to enhance overall company profitability. It has two trading businesses:

·              Avisen - Management consultancy specialising in profit improvement and exclusive distributor of Acorn Systems' Software in the UK and Ireland.

·              Storage Fusion Ltd - Independent Software Vendor specialising in storage analytics for the heterogeneous storage estate delivered using Software as a Service (SaaS) architecture.

Avisen

Overview

Avisen, the Group's management consultancy business, focuses on providing global companies with advice in relation to improving overall company profitability.  One of the key tools that Avisen uses during this process is a software technology known as Acorn Systems.  Based on a costing methodology designed by Harvard Professor, Prof Dr Robert Kaplan and Steve Anderson who is on the Board of the Company, Acorn uses transaction level cost allocation to reveal profit improvement opportunities across the enterprise's customers, products, segments, vendors, channels and processes.  This enables clients to make fact-based, profit-focused decisions which Avisen then help them implement.  Although niche, the Avisen brand is uniquely positioned as it has the exclusive UK distribution rights for Acorn Systems' products and global distribution rights outside of the USA and a skilled team of Technical and Business Consultants.

Avisen has built over the last year a platform to sell its Acorn Systems solutions by providing pilots to various Blue Chip customers including Tesco Direct and Unilever.  This has proved the product offering and provided a platform to sell Avisen's services and resell the Acorn software across the market. 

Avisen's target market and competitors

Avisen's target market is quite well defined.  A typical client is a company with revenues in excess of £100m and with high-volumes of transactions where they understand the total cost of running the business but can't see how each product, customer or channel is driving up that cost. These are sectors such as fast moving consumer goods, distribution, retail, financial services, professional services and pharmaceuticals.

Avisen's competitors are distributors of other profitability management software (SAP, Oracle, Prodocapo, SAAS Institute etc). Avisen'sfocus is on building recurring revenue from software sales and support contracts. This enables Avisen to work with and provide paid services to the "Big 4" consulting companies and other niche consultancy businesses providing profitability improvement services using Acorn. Avisen marketsdirectly to these businesses and to the finance and operational executives of itstarget clients.

The Group continually assesses the demand for its products and services in the market place and adapts its product offerings and pricing strategies to support this.  It has focused the business on helping the large corporate market understand the true cost and profitability of their customers, products and operations as well as providing support in reconfiguring them.  Avisen sees the most interest for the use of its software and services in:

·              Logistics and distribution, to understand the network cost of delivered and returned goods and reconfigure supply chain based on the detailed analysis that Avisen provides.

·              In FMCG and retail, to move past gross margin and understand the actual delivered margin from products and services through the supply chain in order to see true customer profitability.

·              In financial services, to understand the profitability of individual customers, segments and products by allocating all costs and revenues to that grouping.

·              In shared services and outsourcing, to build transparent "charge-back" mechanisms to allocate cost to the business units that consume them.

·              In healthcare, to track the cost of patients through a hospital or other care setting and the actual costs associated with different procedures.

The Scheme Offer relates to shares of a UK company and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the proxy solicitation or tender offer rules under the US Securities Exchange Act of 1934. Accordingly, the Scheme is subject to the disclosure requirements, rules and practices applicable in the United Kingdom to schemes of arrangement, which differ from the requirements of the US proxy solicitation and tender offer rules. However, if Avisen were to elect to implement the Scheme Offer by means of a takeover offer, such takeover offer will be made in compliance with all applicable laws and regulations, including the US tender offer rules, to the extent applicable.

Unless otherwise determined by Avisen or required by the City Code, and permitted by applicable law and regulation, the Scheme Offer will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Scheme Offer by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this Announcement and all documents relating to the Scheme Offer are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this Announcement and all documents relating to the Scheme Offer (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or from such jurisdictions where to do so would violate the laws in that jurisdiction.

The availability of the Scheme Offer to 1Spatial Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable requirements.

"Corporate Performance Management" or "CPM"	corporate performance management is a set of processes that help organisations optimise their business performance.  It is a framework for organising, automating and analysing business methodologies, metrics, processes and systems that drive business performance.  CPM helps businesses make efficient use of not only their financial, but also their human, material and other resources;
"Data Providers"	data providers are comprised of the world's public sector National topographic mapping and cadastral agencies;
"Direct Attached Storage" or "DAS"	a digital storage system directly attached to a server or workstation, without a storage network in between;
"Geographic Information System"	a geographic information system (GIS), geographical information system, or geospatial information system is any system that captures, stores, analyses, manages, and presents data that are linked to location. In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology. GIS systems are used in cartography, remote sensing, land surveying, utility management, natural resource management, urban planning, emergency management, navigation and localised search engines.  As GIS is a system, it establishes boundaries that may be jurisdictional, purpose or application oriented for which a specific GIS is developed;
"INSPIRE"	infrastructure for Spatial Information in the European Community (INSPIRE).  The INSPIRE directive 2007/2EC, March 2007 aims to create a European Union (EU) spatial data infrastructure. This will enable the sharing of environmental spatial information among public sector organisations and better facilitate public access to spatial information across Europe. To ensure that the spatial data infrastructures of the Member States are compatible and usable in a Community and transboundary context, the Directive requires that common Implementing Rules (IRB) are adopted in a number of specific areas (Metadata, Data Specifications, Network Services, Data and Service Sharing and Monitoring and Reporting). These IRs are adopted as Commission Decisions or Regulations, and are binding in their entirety;
"Key Performance Indicators" or "KPI's"	ways to periodically assess the performances of organisations, business units, and their division, departments and employees. Accordingly, KPIs are most commonly defined in a way that is understandable, meaningful and measurable;

The UK, throughdata.gov.uk has published principles around the transparency (use, re-use, availability, timeliness, sharing and maintenance) of Public Data.  The Public Sector Transparency Board, established by the UK Prime Minister, will drive forward the Government's transparency agenda, making it a core part of all government business and ensuring that all departments meet the deadlines set for releasing key public datasets. In addition, it is responsible for setting open data standards across the whole public sector, listening to what the public wants and then driving through the opening up of the most needed data sets;
