FOR IMMEDIATE RELEASE CONTACT: Peter A. Guglielmi 04/14/99 (630) 378-6111 	TELLABS BEGINS 25th YEAR WITH BEST FIRST QUARTER IN HISTORY Lisle, Ill. - Telecommunications-equipment manufacturer Tellabs, Inc., announced Wednesday that it began its 25th year of operation with the highest sales and earnings for any first quarter in company history. It was the company's second- best quarter, exceeded only by the all-time record sales and operating earnings reported in the fourth quarter of 1998. Sales for the first quarter, ended April 2, were $469,651,000, up 43.4 percent from $327,502,000 a year earlier. Net income for the first quarter was $103,718,000, up 52 percent from $68,244,000 a year earlier. Earnings per share of common stock on a diluted basis for the first quarter were 52 cents, compared with 37 cents for the first quarter of 1998. "Tellabs got off to a robust start in 1999, driven primarily by continuing strong demand across our major product lines," said Tellabs President and CEO Michael J. Birck. "Sales of our TITAN (r) digital cross-connect system family exceeded last year's first-quarter level by 48.9 percent, driven by strong demand for the SONET-based TITAN 5500 and 532L systems. MartisDXX (tm) system sales were up 21.2 percent. Echo canceller sales, following strong growth at the end of 1998, increased 42 percent, and CABLESPAN (r) system sales grew meaningfully, as that product continues to gain acceptance in the marketplace." During the quarter, Tellabs announced the newest member of its TITAN transport family, the TITAN 4500GS global services delivery system. This platform delivers global services over SDH and SONET networks, and was designed in close collaboration with major global super-carriers whose networks traverse international boundaries. The system gives carriers new flexibility and economies for delivering services (Frame Relay, ATM, Internet, digital private line, cable data and telephony, or video) intact between a SONET environment such as the United States or Canada and an SDH environment like Europe, Latin America or the rest of the world. Availability of the TITAN 4500GS system is expected in May 1999. "In addition to the TITAN 4500GS system and the AN2100 Gateway Exchange (tm), introduced in late 1998, Tellabs looks forward to introducing two more major new product platforms during 1999," Birck continued. "During the summer, we expect to bring to field trial an optical networking system that uses DWDM technology to address metropolitan service applications. Late in the year, we expect to field-trial a large capacity, ATM-based, broadband transport manager that complements our TITAN family of digital cross-connect systems." Tellabs designs, manufactures, markets and services voice and data transport and access systems. The company's products are used worldwide by the providers of communications services.
