Strategic rationale . The acquisition of Sema, a leading diversified IT and business services company, will accelerate the implementation of Schlumberger's strategy of providing end to end information solutions to customers in selected growth markets. Sema will enhance Schlumberger's capabilities and critical mass in systems integration and the range of IT skills which Schlumberger requires to serve its present and future customer base. It should also allow Schlumberger to realise revenue synergies as a result of cross selling its core competencies in network development and management, IP-based applications, data management, smart cards and security application products. . The board of directors of Schlumberger believes this combination will: 1 - provide the critical mass and scale to deliver end-to-end information solutions for a global customer base in key vertical markets and offer significant cross-selling opportunities; - be particularly beneficial to the core oilfield services business of Schlumberger which will be able to provide its customers with fully integrated information solutions, comprising domain knowledge and expertise, IT implementation and consulting skills, and global support to E&P companies; - allow Schlumberger's Resource Management Services and Sema's Energy/Utilities business unit to exploit their complementary geographical reach and technological offering to create significant growth opportunities, primarily by combining both solutions approaches and thereby facilitating access to larger, more complex contracts requiring end-to-end solutions; and - through the combination of Sema's recognised systems integration expertise and telecom product offering breadth (customer care and billing, prepaid and SMS) and Schlumberger's smartcards and systems activities, which will be enhanced by the forthcoming acquisition of "Bull CP8" from Bull SA, further accelerate the creation of a leading global technology services provider for the telecommunications industry. Summary of the Offer terms . The Offer will be made on the basis of 560 pence in cash for each Sema Share and 1,120 pence in cash for each Sema ADS (each ADS represents 2 Sema Shares). . The Offer values the entire issued and to be issued share capital of Sema at approximately (Pounds)3.6 billion (US$5.3 billion) (fully diluted for the exercise of all outstanding options). . The Offer represents a premium of approximately 42 per cent. to the middle market price of 395 pence per Sema Share at the close of business on 2 February 2001, being the last dealing day prior to the announcement by Sema that it had received approaches that may or may not lead to an offer for the Company and 18 per cent. to the middle market price of 475 pence per Sema Share at the close of business on 9 February 2001, the last dealing day prior to this announcement of the Offer. . Schlumberger Investments has received irrevocable undertakings to accept the Offer from Sema Directors in respect of their own beneficial holdings representing approximately 0.1 per cent. of Sema's existing issued share capital. Schlumberger Investments has also received undertakings to accept the Offer from France Telecom and BNP Paribas representing approximately 16.9 per cent and 5.1 per cent. respectively of Sema's existing issued share capital. Subject to the right for Schlumberger Investments to improve upon the price of any competing offer, the undertakings from France Telecom and BNP Paribas will cease to be binding if a competing offer is made at a price in excess of 600 pence per Sema Share, before the end of the day falling 17 days after the Offer Document is posted. . The Sema Board, which has been so advised by Credit Suisse First Boston and Rothschild, intends unanimously to recommend the Offer. In providing advice to the Sema Board, Credit Suisse First Boston and Rothschild have taken into account the Sema Board's commercial assessments. . Lehman Brothers is acting as Corporate Broker to Schlumberger Investments. Credit Suisse First Boston de Zoete & Bevan Limited and HSBC Investment Bank plc are acting as Corporate Brokers to Sema. 2 Commenting on today's announcement, Euan Baird, Chairman and Chief Executive Officer of Schlumberger, said: "The acquisition of Sema will enable us to accelerate significantly our existing information technology strategy. It will enhance our capabilities and critical mass in systems integration, widen our IT skills and create revenue synergies in many of our core competencies. I am confident that the excellent personal relationships which we have developed with senior Sema management and strong cultural fit between our organisations will facilitate the integration and subsequent growth of Sema within the Schlumberger group." Pierre Bonelli, Chief Executive Officer of Sema, added: "I am delighted to announce that we have reached agreement with Schlumberger. The terms of the Offer reflect the underlying strengths of Sema. Schlumberger will provide Sema with the scale and stability to continue to prosper. The combination will also generate significant new opportunities to develop the business. Importantly Sema staff and customers will benefit from the strong culture and business fit."

Introduction The Boards of Schlumberger Investments and Sema announce that they have reached agreement on the terms of a recommended cash offer (the "Offer") to be made by Lehman Brothers on behalf of Schlumberger Investments, a wholly-owned subsidiary of Schlumberger, for the entire issued and to be issued share capital of Sema. The Offer will be made on the basis of 560 pence in cash for each Sema Share and 1,120 pence in cash for each Sema ADS (each ADS represents 2 Sema Shares). The Offer values the entire issued and to be issued share capital of Sema at approximately (Pounds)3.6 billion (US$5.3 billion) (fully diluted for the exercise of all outstanding options). The Offer represents a premium of approximately 42 per cent. to the middle market price of 395 pence per Sema Share at the close of business on 2 February 2001, being the last dealing day prior to the announcement by Sema that it had received preliminary approaches which may or may not lead to an offer for the Company and 18 per cent. to the middle market price of 475 pence per Sema Share at the close of business on 9 February 2001, the last dealing day prior to this announcement of the Offer. 6 Schlumberger has received undertakings to accept the Offer in respect of approximately 22 per cent. of Sema's existing issued ordinary share capital. Further details of these undertakings are provided in paragraph 4 below. Lehman Brothers is acting as Corporate Broker to Schlumberger Investments. Credit Suisse First Boston de Zoete & Bevan Limited and HSBC Investment Bank plc are acting as Corporate Brokers to Sema. In addition, Morgan Stanley Dean Witter has given financial advice to Schlumberger in the context of the Offer. 2. The Offer The Offer, which will be made on the terms and subject to the conditions summarised below and in Appendix I to this announcement, and to the further terms which will be set out in full in the Offer Document and the accompanying Acceptance Form(s), will be made on the following basis: for each Sema Share 560 pence in cash for each Sema ADS (each ADS represents 1,120 pence in cash 2 Sema Shares) The Offer will extend, subject to the terms and conditions to be set out in the Offer Document and Acceptance Form(s), to all Sema Shares unconditionally allotted or issued on the date on which the Offer is made and any further Sema Shares unconditionally allotted or issued while the Offer remains open for acceptance (or such earlier date as Schlumberger Investments may, subject to the Code, decide). In conjunction with the offer being made to Sema Shareholders an offer is being made to holders of Sema ADSs to tender the Sema Shares underlying such ADSs into the Offer. The Sema Shares will be acquired by Schlumberger Investments pursuant to the Offer fully paid and free from all liens, charges, equitable interests, encumbrances and other third party rights and interests of any nature whatsoever and together with all rights now or hereafter attaching thereto, including the right to receive and retain all dividends and other distributions (if any) declared, made or paid hereafter. If sufficient acceptances are received and/or sufficient Sema Shares are otherwise acquired, Schlumberger Investments intends to apply the provisions of Sections 428 to 430F (inclusive) of the Act to acquire compulsorily any outstanding Sema Shares to which the Offer relates. When the Offer becomes or is declared unconditional in all respects, Schlumberger Investments intends to procure the making of an application by Sema for the removal of Sema Shares from the Official List and for the cancellation of trading in Sema Shares on the London Stock Exchange's market for listed securities. It is anticipated that cancellation of listing and trading will take effect no earlier than 20 business days after the Offer becomes or is declared unconditional in all respects. Schlumberger Investments would also intend to apply for de-listing of the Sema Securities from the Nasdaq National Market and from Euronext Paris. Such de-listings and cancellation would significantly reduce the liquidity and marketability of any Sema Securities not assented to the Offer. 3. Recommendation The Sema Board, which has been so advised by Credit Suisse First Boston and Rothschild, considers the terms of the Offer to be fair and reasonable. Accordingly, the Sema Directors intend unanimously to recommend Sema Securityholders to accept the Offer. Directors have irrevocably undertaken to accept the Offer in respect of their own beneficial holdings comprising 497,612 7 Sema Shares in aggregate, representing approximately 0.1 per cent. of Sema's existing issued share capital. In providing advice to the Sema Board, Credit Suisse First Boston and Rothschild have taken into account the Sema Board's commercial assessments. 4. Undertakings to accept the Offer Schlumberger Investments has received undertakings to accept the Offer from certain Sema Securityholders as set out below. The percentage figures are based on the number of Sema Shares in issue on 9 February 2001, being the last practicable date prior to the date of this announcement.

This fee is payable on either of the following events: (a) the Board of Directors of Sema withdrawing or modifying their recommendation of the Offer, or approving or recommending a competing offer for, or certain other competing transactions in relation to, Sema in a manner which is adverse to Schlumberger Investments and the Offer subsequently lapsing or being withdrawn; or (b) a competing offer for, or certain other competing transactions in relation to, Sema being announced after the date of this announcement, but prior to the Offer lapsing or being withdrawn and such competing offer or another competing offer becoming or being declared unconditional in all respects. 6.

Background to and reasons for the Offer For several years, Schlumberger has been actively exploiting IT to improve its internal business processes and efficiencies, to grow the company's existing businesses and to develop new IT-based revenue generation opportunities. This focus on leveraging IT has taken the form of extensions of existing Schlumberger business groups and also the creation of new businesses which leverage Schlumberger's long term expertise in network development and management, IP based applications, backed by a strong culture of global support. Such initiatives have been ongoing in all three of the Schlumberger core vertical markets: oilfield services, wireless telecom and utilities. 10 Schlumberger has concluded that it needs to continue to add strong IT technology, systems integration and consulting competencies on a global scale to both accelerate the growth in its core vertical markets and to establish itself as a leading information solutions provider in those core vertical markets. The acquisition of Sema, a leading diversified IT and business services company, will accelerate the implementation of Schlumberger's strategy of providing end to end information solutions to customers in selected growth markets. Sema will enhance Schlumberger's capabilities and critical mass in systems integration and the range of IT skills which Schlumberger requires to serve its present and future customer base. It should also allow Schlumberger to realise revenue synergies as a result of cross selling its core competencies in network development and management, IP-based applications, data management, smart cards and security application products. The board of directors of Schlumberger believes this combination will: . offer a compelling opportunity to add scale and critical mass, enabling cross-penetration of new markets and customers with existing and future product/services offerings; . provide the critical mass and scale to deliver end-to-end information solutions for a global customer base in key vertical markets and offer significant cross-selling opportunities; . be particularly beneficial to the core oilfield services business of Schlumberger which will be able to provide its customers with fully integrated information solutions, comprising domain knowledge and expertise, IT implementation and consulting skills, and global support to E&P companies. The systems integration and e-transformation technologies and expertise provided by Sema will enable Schlumberger to deepen its relationships with its key customers by providing a comprehensive infrastructure support service on a global basis and capture a significant share of the emerging, fast growing global E&P IT transformation market; . allow Schlumberger's RMS and Sema's Energy/Utilities business unit to exploit their complementary geographical reach and technological offering to create significant growth opportunities, primarily by combining both solutions approaches and thereby facilitating access to larger, more complex contracts requiring end-to-end solutions. Schlumberger's Resource Management Services specialising in the North American solutions market for automatic meter reading products and services, related data management via CellNet based technologies and consulting services provided by Convergent Group combined with Sema's presence in the European solutions market for power exchange, customer management and utility economics are expected to yield significant cross selling opportunities; and . through the combination of Sema's recognised systems integration expertise and telecom product offering breadth (customer care and billing, prepaid and SMS) and Schlumberger's smartcards and systems activities, which will be enhanced by the forthcoming acquisition of "Bull CP8" from Bull SA, further accelerate the creation of a leading global technology services provider for the telecommunications industry. 10. Management and employees Schlumberger Investments recognises the importance to Sema's business of the skills and experience of Sema's management team. It intends, with Sema's senior management, to develop incentivisation arrangements for Sema's employees going forward that reflect that importance. 11 Schlumberger Investments has given assurances to the Sema Board that the existing employment rights, including pension rights, of the management and employees of the Sema Group will be fully safeguarded in accordance with all applicable laws. 11. Sema Share Option Schemes The Offer will extend, subject to the terms and Conditions to be set out in the Offer Document and Acceptance Form(s), to all Sema Shares unconditionally allotted or issued fully paid (or credited as fully paid) upon exercise of options under the Sema Share Option Schemes while the Offer remains open for acceptance (or until such earlier date as Schlumberger Investments may, subject to the provisions of the Code, determine). Appropriate proposals will be made to the holders of options under the Sema Share Option Schemes, to the extent that options are not exercised, once the Offer becomes or is declared unconditional in all respects. 12. Financing Schlumberger Investments intends to fund the Offer from a combination of its existing cash resources and additional bank facilities arranged by JP Morgan plc, BNP Paribas, Citibank/Schroder Salomon Smith Barney and Lehman Brothers, for the purposes of the Offer. The Offer will not be conditional upon any financing arrangements. 13.
