EXPLANATORY STATEMENT PURSUANT TO SECTION 173(2) OF THE COMPANIES ACT, 1956

The following Explanatory Statement sets out all material facts relating to the accompanying Notice of the Extraordinary General Meeting to be held on Friday, 06 July 2012.

iGATE Corporation through its subsidiaries Pan-Asia iGATE Solutions and iGATE Global Solutions Limited (iGATE Group or iGATE) acquired majority shareholding in Patni Computer Systems Limited (Patni or Company) in May 2011. Thereafter, iGATE Group completed the integration of various areas of both iGATE and Patni and also has delisted Patni from the Indian Stock Exchanges. As on date, iGATE Group holds 93% of the equity capital of the Company.

iGATE is a well established name in the IT & ITES services industry for several years and is a well known in the Indian and International markets. iGATE Corporation being the ultimate parent corporation in the iGATE Group is listed on the NASDAQ Global Select Market List under the symbol “IGTE”. iGATE enjoys the trust and goodwill of its customers, suppliers, employees, shareholders and the investor community in general by the trade name “iGATE”. Therefore, to represent the holding of iGATE Group in the Company and to leverage the brand name and goodwill of both the entities it is felt that word “Patni” appearing in the name of the Company is no longer required and the word be replaced with “iGATE” as the entity is now part of the iGATE Group which has worldwide presence and recognition.

It is therefore, desirable and in the interest of the Company that the name of the Company be changed from Patni Computer Systems Limited to iGATE Computer Systems Limited.

It may be noted that the change of name shall not affect any rights or obligations of the Company or render defective any legal proceedings by or against the Company and the assets and liabilities of the Company will remain the same.

Accordingly, it is proposed to seek the approval of members as per the resolution proposed.

The Board recommends the resolution for your approval.

No Director, except Mr. Phaneesh Murthy, Mr. Shashank Singh and Mr. Göran Lindahl, being nominees of iGATE are concerned or interested in the resolution.

		By Order of the Board of the Directors
		For Patni Computer Systems Limited
