HANOVER, Md. -- May 15, 2013

Commitment to excellence over the past year has earned Ciena^® Corporation
(NASDAQ: CIEN), the network specialist, recognition as a 2013 AT&T Supplier
Award winner for its support of affiliates of AT&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,
innovative products and services to our business and residential customers,”
said Tim Harden, president of AT&T Supply Chain and Fleet Operations. “We’re
successful on that front in large part thanks to extraordinary suppliers like
Ciena that consistently go above and beyond, exceeding our expectations and
helping exceed those of our customers as well.”

Ciena was one of only six suppliers to receive the 2013 AT&T Supplier Award
for its work in helping AT&T deliver outstanding service to its customers
during the past year. Ciena was recognized for its contributions across a
broad scope of criteria including creative cost management solutions,
teamwork, customer service, product/service performance, sustainability, and
supplier diversity results.

“We are incredibly honored to once again receive this recognition from AT&T, a
long-time strategic collaborator with Ciena,” said Gary Smith, president and
CEO at Ciena. “For more than 15 years, including as a provider in multiple
network domains, we have worked with AT&T to help them meet the ever growing
demands on their network and deliver world-class services to their customers.
As the next shift in network architecture gets underway, we look forward to
continuing our collaborative efforts with AT&T to drive network innovation.”

As part of its annual Supplier Award Program, AT&T took out a half-page ad in
the May 14 edition of The Wall Street Journal to publicly thank the selected

*AT&T products and services are provided or offered by subsidiaries and
affiliates of AT&T Inc. under the AT&T brand and not by AT&T Inc.
