                             Chairman's Statement                              

Despite the challenging market environment, the Board of Microgen reports a
strong performance for the year ended 31 December 2002, in terms of both
operating results and the strategic development of the Group. The three
operating divisions are all profitable and the two acquisitions made during the
year have been successfully integrated, with the objectives behind each
acquisition being realised.

The Group continues to focus on information management solutions which enable
customers to manage their data to enhance business processes and information.
These solutions are delivered through managed services, software products and
consultancy.

FINANCIAL SUMMARY

For the year ended 31 December 2002, Microgen increased operating profit before
tax, exceptional items and goodwill amortisation by 83% to �2.0 million on
revenue of �25.3 million (2001: �1.1 million on revenue of �21.0 million). 
Operating costs have been well managed during the year, reducing by �3.5
million on continuing activities compared with 2001. Together with the
acquisition integration strategy, this cost management has delivered a
significant improvement in operating margin to 8.0% (2001: 5.3%), while
increasing investment in new products and services.

Profit before tax, exceptional items and goodwill amortisation increased by 33%
to �2.2 million (2001 : �1.7 million). Adjusted earnings per share, (to reflect
the underlying operating performance; see note 3) was 2.6p, a 13.0% increase on
prior year (2001: 2.3p). As a result of the integration of the acquisitions, a
one-time exceptional charge of �1.5 million has been taken, primarily due to an
excess property provision. Therefore the Group produced a net loss on ordinary
activities after tax and goodwill amortisation of �2.6 million (2001 : net
profit of �0.7 million, restated following adoption of FRS19) and a fully
diluted loss per share of 4.2p (2001 : eps  of  1.5p, restated following
adoption of FRS19)

As a result of the acquisitions,  headcount, including external contractors,
peaked in March at 342, but was reduced to 289 at 31 December 2002 (31 December
2001 : 234).

The Group produced a positive operating cash flow of �2.6 million and has
maintained a strong balance sheet. Following the two acquisitions and a share
buy-back of 9.8% of the issued share capital, the Group had a gross cash
balance of �9.8 million with net free cash of �8.3 million at 31 December 2002.
(The difference in gross cash and net free cash takes account of loan notes and
deferred consideration resulting from acquisitions, and net corporation tax
payable. All deferred considerations have now been finalised.) After careful
consideration, the Board has concluded not to recommend a dividend (2001 : nil)
but believe that investment in the strategic development of the Group and/or
buy-back of shares is more appropriate in the current market.

In accordance with FRS11, the Board has conducted a review of the goodwill held
on the balance sheet. While market sentiment may infer an impairment of
goodwill, the accounting treatment accepts the results of a discounted cash
flow model and, on this basis, the Board have determined that there is
currently no justification to take a charge for impairment of goodwill on the
acquisitions of Kaisha Technology (1999), Telesmart Developments (2000) or OST
Business Rules (2002). With regard to the goodwill associated with the
acquisition of Wishstream in September 2002, the Board have decided to write
the goodwill off in the first year of acquisition.

MICROGEN-TELESMART

Microgen-Telesmart provides added-value transactional services in billing,
payment and hosted database and document management, where Microgen adds value
by processing, distributing, storing and analysing data for a wide variety of
applications, including the Group's market-leading business-to-business ("B2B")
e-billing service. This position in the e-billing market was further reinforced
in September through the acquisition of Wishstream Limited.

The division is also one of the leading providers of payment software and
solutions. The next generation of BACS software is currently being developed in
the Group's development facility in Poland and Microgen has been participating
in a deployment programme of the new BACS IP technology with a leading UK bank.

For the year ended 31 December 2002, revenue from the division was �10.9
million, producing an operating profit of �1.4 million before Group overhead
(2001: revenue of �12.2 million produced an operating profit of �1.0 million).
The revenue decline in the legacy print business continued as anticipated while
the annual revenue growth rate in managed e-services (database management,
payment and billing) increased to 34% (2001 : 24%), such that during the second
half of the year, the legacy print business was less than half of the total
divisional revenue for the first time. This transition also produced the
increase in operating margin to 13.1% (2001 : 8.4%), despite a significant
increase in investment in product/service development.

MICROGEN-KAISHA

Microgen-Kaisha is the Group's consultancy division applying data warehousing
and application integration techniques to transform data into information. By
combining these skills with the provision of managed services and software
available through the Group's other businesses, Microgen-Kaisha has developed a
number of new business streams, including :

Application Management : Providing greater forward visibility, this business
area accounted for over 20% of the division's revenue in the second half of
2002 and benefits from the managed services infrastructure and expertise of the
Microgen-Telesmart business.

Payment Solutions : Using the technology and expertise from the
Microgen-Telesmart payments business, large payment solutions have been
deployed as a combination of software product and consultancy.

Enterprise Information Integration : Developed from the Microgen-OST
technology, but targeted at the commercial sector, this new product will be
launched in the first half of 2003. This development continues to differentiate
Microgen-Kaisha by combining the application of Group IPR using the skill base
of application integration and data transformation.

Considering the deterioration in the IT consultancy market, Microgen-Kaisha
produced a laudable performance, achieving the strategic objective of
maintaining profitability at 25% (2001: 25%). For the year ended 31 December
2002, revenue for the division was �6.6 million, producing an operating profit
of �1.6 million before Group overhead and goodwill amortisation (2001 : revenue
of �8.8 million, operating profit of �2.2 million). The legacy support services
now account for less than 10% of the division's revenue.

MICROGEN-OST

Microgen-OST was established following the acquisition of OST Business Rules
Ltd in February 2002.  The division provides business rules based application
integration solutions, using OST-developed software, incorporating user-defined
business rules to integrate the front, middle and back office systems of major
financial institutions. In addition the cross-selling of Microgen-Kaisha
consultancy services into the financial services sector made progress in the
second half of the year, enabling Microgen-OST to offer a broader range of
services to their customer base.

During the year, the division was affected by the slow down in the financial
services sector, with project deferrals and pressure on consultancy fee rates.
Action to realign the cost base has been taken during the second half of the
year, including a property provision associated with the relocation of the
London offices, in order to position the business more appropriately for 2003.

Despite these difficult market conditions, the division produced a creditable
performance. For the period from completion of the acquisition to 31 December
2002, revenue of �7.8 million produced an operating profit before Group
overhead, exceptional items and goodwill amortisation of �1.1 million, an
operating margin of 14%.

GROUP DEVELOPMENT CAPABILITY

One of the assets acquired with OST was a high quality, cost-effective software
product development operation based in Wroclaw, Poland. In order to realise the
benefits of scale and establish consistency of process, a Group Development
operation was established in Q3 such that all development programs are managed
by a Group Development Director responsible for the two facilities in Poland
and UK. The Poland development centre is focused on software product
development while the UK development operation primarily supports the
Microgen-Telesmart services business.

A number of development programs have been transferred to Poland and new
products for all three divisions are scheduled for launch in the first half of
2003. These include :

The next generation BACS IP payment products, currently being implemented in
the deployment programme.

Two new reconciliation products, based on the same OST-based technology, but
with one solution for  commercial applications, compatible with the Payment
Solutions business (Microgen-Telesmart & Microgen-Kaisha) and a high end
product designed for the financial services industry (Microgen-OST).

A new Enterprise Information Integration ("EII") product for Microgen-Kaisha.
Using the core technology of OST Business Rules, the EII product has been
designed for commercial system integration applications.

These new products will support  Microgen's position at the forefront of
Information Management technology.

Development staff now account for approximately 20% of the headcount of the
Group and consequently the Group's research and development expenditure
increased significantly in 2002 to �2.5 million (2001 : �1.3 million). In
accordance with the Group's accounting policy, all research and development
expenditure is charged to the profit and loss account as incurred.

SHARE BUY-BACK

During the second half of the year, 6,320,000 shares equivalent to 9.8% of the
issued share capital of the Group were purchased for cancellation for a total
consideration of �1.96 million. At the forthcoming Annual General Meeting, the
Board shall propose to continue this program and will be seeking authorisation
to purchase 14.99% of the outstanding issued share capital of the Group.
However, it should not be assumed that the Board will exercise any or all of
the authorisation which will be a considered decision determined by the Board
at the appropriate time, taking into account the strategic objectives of the
Group, enhancement of earnings per share and the best interests' of
shareholders.

FUTURE PROSPECTS

While the Group has experienced the impact of the slowdown in the IT sector,
the Board's strong financial management continues to prove effective in
maintaining both profitability and positive operating cash flow. Furthermore,
during 2002, Microgen completed two acquisitions, OST Business Rules Ltd and
Wishstream Ltd and the strategic benefits anticipated at the time of each
acquisition are being achieved, with both of these businesses now successfully
integrated into the Group. This strategy of active integration of acquisitions
to realise the operational and cost benefits of scale and thereby deliver
increased profitability has proven successful. As the business models of
Microgen-OST and Microgen-Kaisha converge with consultants from both divisions
being deployed on projects in the Financial Services sector and the OST
Business Rules technology being repackaged for the Commercial sector, the Board
has now decided to merge these two business units into a single operating
division.

In planning for 2003, the Board has done so on the assumption that market
conditions will not improve in the near term. However the actions taken in
integrating the acquisitions, together with the disciplined management approach
adopted by the Board, have positioned the Group appropriately for the year
ahead. Furthermore, the Board continues to believe that the IT sector is likely
to consolidate and will continue to explore strategic opportunities for the
further development of Microgen.

In summary, despite the deterioration in market conditions, Microgen has
delivered improved operating margin on increased revenue, producing growth in
operating income and adjusted (operational) earnings per share, together with
strong positive cash flow. The Board is pleased with this performance and with
the organic and strategic development of the Group during the past year.

Prior Year Adjustment

Microgen Plc has adopted FRS 19 deferred tax for the first time in 2002 which
has resulted in a deferred tax asset of �796,000 (2001as restated: �930,000)
due to timing differences relating to accounting provisions and capital
allowances. In addition the UK group had a potential deferred tax asset of �
420,000 (2001 as restated: �260,000) relating to taxable trading losses carried
forward which has not been recognised in the accounts. 

Within the prior tax charge, �128,000 relates to additional UK tax payable in
respect of dividends received in 1997 from the Group's former German subsidiary
upon which agreement of the underlying tax rate was only reached in 2002.

The differences between the total current tax charge and the amount calculated
by applying the national rates of corporation tax (UK 30%, Poland 28% US 35%)
to the (loss)/profit on ordinary activities before tax is as follows:
