Linthicum, MD — 06/12/2006

Commitment to excellence over the past year has earned Ciena® Corporation (Nasdaq: CIEN), recognition as an outstanding supplier to AT&T Inc. (NYSE: T), one of the world’s leading data, voice, wireless and Internet services providers.

“We are proud of our long-standing tradition of providing unparalleled products and services to our business and residential customers,” said Maureen Merkle, President, AT&T Procurement. “We’re successful on that front in large part thanks to supplier partners like Ciena that consistently go above and beyond the call of duty.”

Ciena received one of 49 supplier recognition awards for its work in helping AT&T deliver outstanding service to its customers during the past year. Ciena was recognized for its contributions in the Creative Cost-Management Solutions category. 

“This recognition is a testament to Ciena’s commitment to provide our customers with quality solutions that exceed performance objectives and deliver maximum network value,” said Mike Aquino, Ciena’s senior vice president, Worldwide Sales.

As part of its annual supplier recognition program, AT&T took out a half-page ad in the June 7, 2006, edition of The Wall Street Journal to publicly thank the selected companies.
