Intelligroup Enhances NTT DATA’s ERP Presence

Tokyo, Japan, June 14, 2010 / Princeton, NJ, June 14, 2010 — NTT DATA Corporation (Tokyo Stock Exchange, First Section: 9613) (“NTT DATA”), the Japan-based leading IT services company, and Intelligroup, Inc. (OTC: ITIG) (“Intelligroup”), a US-based IT services company, today announced that they have entered into a merger agreement pursuant to which NTT DATA will acquire Intelligroup for approximately US$199 million through an all-cash tender offer, followed by a second-step merger to acquire all remaining shares at the same price paid in the tender offer.

NTT DATA, through its wholly-owned subsidiary, Mobius Subsidiary Corporation, will make an offer to purchase all outstanding shares of Intelligroup common stock for US$4.65 per share, which represents a 21.1% premium to Intelligroup’s average closing stock price over the last three-month period ended June 11, 2010, and a 27.7% premium over the closing price of Intelligroup’s common stock on June 11, 2010. The tender offer is scheduled to commence within 6 business days and will expire after 20 business days unless the offer is extended. The tender offer is conditioned on the tender of more than a majority of Intelligroup’s outstanding shares on a fully-diluted basis, and various other conditions, including customary regulatory approvals. The transaction is not conditioned on financing.

The transaction was unanimously approved by the Boards of Directors of both Intelligroup and NTT DATA, and the Board of Directors of Intelligroup will recommend that Intelligroup’s stockholders tender their shares in the offer. In connection with the offer, SB Asia Infrastructure Fund, LP and Venture Tech Assets Private Ltd, which collectively hold approximately 62.9% of Intelligroup’s outstanding common stock, have agreed to tender their shares into the offer.

Intelligroup is an enterprise applications systems integrator providing consulting, implementation, testing, application management, infrastructure management, and other IT services primarily related to SAP, Oracle and Microsoft applications for global corporations.

Intelligroup currently provides SAP, Oracle and related services to major corporations located in the US, UK, Denmark, Japan, India and the Middle East, which would complement NTT DATA’s services/solutions business and its customer base for such services.

The transaction would give NTT DATA access to Intelligroup’s blue-chip client base and specialized knowledge of SAP and Oracle. NTT DATA would also benefit from Intelligroup’s deep industry experience and solutions focused on the life sciences, high-tech and discrete manufacturing, and consumer packaged goods verticals and its efficient global delivery model, enabled by world-class delivery centers in India. Furthermore, the transaction would result in better service for Intelligroup’s and NTT DATA’s global client bases, through coordination and cooperation with NTT DATA global affiliates.
