Cognizant Added to the NASDAQ-100 Index; Cognizant is Only IT Services Firm in Index.

TEANECK, N.J. -- Cognizant Technology Solutions Corporation (Nasdaq: CTSH), a leading provider of IT services, today announced that it will be added to the NASDAQ-100 Index, effective December 29, 2004.

The NASDAQ-100 Index, launched in 1985, is composed of the 100 largest non-financial stocks listed on the NASDAQ Stock Market based on market capitalization. Index securities are ranked by market value and evaluated annually to determine which securities will be included. The NASDAQ-100 Index Tracking Stock represents ownership in the NASDAQ-100 Trust and is designed to provide investment results that generally correspond to the price and yield of the NASDAQ-100 Index.

"We are the only IT Services firm on the list, and we are the first and only offshore firm to be included in the NASDAQ-100," said Lakshmi Narayanan, President and CEO of Cognizant. "Offshore outsourcing is now mainstream and this trend, combined with our investments in value added services, positions Cognizant to capture a greater percentage of total IT spending. Our unique global delivery model features greater customer intimacy, speed of delivery, and responsiveness and has helped us build deep, fast growing relationships with blue-chip customers. The inclusion in the NASDAQ-100 Index is a clear indication of the strength of our global model and is further validation of Cognizant's leadership status amongst traditional and offshore IT Services firms."

Cognizant has strong expertise in multiple industries including financial services, insurance, retail, healthcare, life sciences, media, telecommunications, manufacturing and logistics. Cognizant has also recently introduced infrastructure management, portfolio analysis and rationalization, business intelligence and testing services.

Forrester forecasts that US spending on IT services and outsourcing will grow to $184 billion in 2005. Meta Group predicts that the market for offshore services will continue to grow nearly 20% annually through 2008.
