Subject: Meridio signs definitive agreement to be acquired by Autonomy

As a valued customer, I wanted to inform you about some exciting news. I’m pleased to tell you that Autonomy (LSE: AU.), an acknowledged market leader in enterprise search and a leader in infrastructure management software for processing unstructured information, and Meridio have reached agreement to combine the companies. Since its founding 10 years ago, Autonomy has been one of the fastest growing public companies in the software space, and its technology is now found in products from almost all of the major software companies, including Meridio.

This move is important for the following reasons:

• Bringing the two companies together gives Meridio significant scale in a number of key financial areas:
  • Autonomy’s revenue growth in 2006 was 161% and its current run rate is in excess of $400 million.
  • Autonomy’s profit growth in 2006 was greater than 500%, with a highly cash generative business model, which enables significant new investment.
  • Autonomy already has the largest R&D budget in its space.
  • The net result of the growth is that Autonomy’s share price has roughly doubled over the past year.
• As a publicly-held company with a market capitalization of approximately $4 billion and over 1,400 employees, Autonomy allows Meridio to immediately gain the benefits of a public company of scale, financial security, distribution and customer base while continuing to operate as an independent entity. I will retain my position as CEO of Meridio.
• Meridio is able to leverage Autonomy’s advanced IDOL technology and incorporate it into our solutions. IDOL will enhance our records management capabilities and accelerate product development of features such as conceptual search and analytics across new unstructured data types like audio and video.

What does this mean for our customers and the market at large?

The acquisition will contribute to Autonomy’s on-going success in redefining information risk management by proactively automating the full spectrum of consolidated records management, archiving, e-discovery, analytics and real-time policy management uniquely in one system. Customers will benefit from a powerful combination of technology leadership and customer-facing strengths in sales, support and professional services.

In closing, I want to assure you that both companies share the same vision, focus and commitment to providing customer-driven solutions and service. While we expect to make many exciting enhancements to our products in the months to come, you will not see any disruption to the products and services we currently provide.

Brian Baird
CEO
Meridio Limited
