FOR IMMEDIATE RELEASE 15 MARCH 2000 SEMA GROUP PLC MERGER WITH LHS GROUP INC. SEMA TO BECOME A WORLD LEADER IN MOBILE COMMUNICATIONS SOFTWARE 1. INTRODUCTION LONDON and ATLANTA - Today, Sema and LHS announce that they have entered into a definitive agreement for the merger of LHS with Sema. The telecoms business of Sema will thereby be combined with LHS to create one of the world's leading suppliers of mobile communications software. The enlarged group will provide its customers with one of the strongest and most extensive offerings of business and operational solutions in the communications industry. Under the terms of the merger, LHS shareholders will be entitled to receive 2.6 new Sema ordinary shares for each LHS common share held at closing. Such new Sema shares will be delivered in the form of Sema ordinary shares, or Sema American Depositary Shares ("ADSs") which will be registered with the SEC and traded on Nasdaq National Market ("NASDAQ"). The merger terms currently represent a value of $69.7 per LHS share and value LHS at $4.7 billion (on a fully diluted basis). Following the merger, existing Sema shareholders will own some 73 per cent. of the combined company and LHS shareholders will own some 27 per cent. (on a fully diluted basis). Sema expects that the transaction will be immediately accretive to earnings per share, excluding goodwill amortisation and before taking account of synergies. In addition Sema expects the combination to generate significant opportunities for revenue enhancement within the next two to three years. Sema's shares will continue to be listed on the London Stock Exchange and the Paris Bourse. Sema will also apply for the new shares to be issued to LHS shareholders in connection with the merger to be listed on the London Stock Exchange and the Paris Bourse and for the ADSs to be listed on NASDAQ. Sema and LHS intend to publish detailed information on the merger for shareholders in approximately two months. Subject to shareholder approval and regulatory consents, closing of the merger is expected to occur early in the second half of 2000. Sema is being advised by Deutsche Bank. LHS is being advised by Goldman, Sachs & Co. HSBC is acting as broker to Sema. 4 2. BACKGROUND TO AND REASONS FOR THE MERGER Sema's stated telecoms strategy is to become the worldwide leader in customer care and billing, prepaid, messaging, value added services and mobile commerce. LHS, as one of the premier organisations in the field of operations support systems, with an extensive worldwide installed customer base, was identified by Sema as an ideal partner for furthering this strategy. 3. BENEFITS OF THE MERGER The combination of Sema's telecoms business with LHS will establish one of the largest suppliers of customer care, billing, messaging and pre-paid solutions to the telecommunications industry worldwide. The enlarged operation will have, in the mobile telecoms sector, more than: - - 2,600 employees - - 350 customer sites worldwide - - 140 million subscribers - - $400 million of revenues In addition, LHS will strengthen the enlarged Sema Group by broadening the scope of the services offered and expanding the depth of technical support. Sema will also benefit from broader geographical coverage and the optimisation of the two companies' research and development efforts. LHS's position as a products based business will increase Sema's exposure to the dynamic telecommunications software sector and thereby enhance its margins. Sema also anticipates that significant opportunities will arise from offering its systems integration, outsourcing and messaging expertise to existing LHS customers. In addition, Sema will look to build on LHS's long experience and excellent working relationships with its partners in the fields of systems integration, telecommunications equipment manufacturing and service delivery. In the internet space, the combination of Sema's recently launched SemaPortal and both Sema's and LHS's support of wireless data (GPRS), IP and WAP services will provide the enlarged group with comprehensive coverage. Allied to this, Sema will be able to market its already established e-commerce business to LHS's existing customer base. 4. PROPOSED DIRECTORS OF SEMA On closing of the merger, Mr. Hartmut Lademacher, chairman and one of the founders of LHS, and Mr. George Schmitt, a director of LHS, will join the board of Sema as non-executive directors. 5.
