FOR IMMEDIATE RELEASE

CIENA ANNOUNCES INTENT TO ACQUIRE INTERNET PHOTONICS; EXPANDS
BROADBAND SERVICE OFFERINGS WITH CARRIER-GRADE ETHERNET
SOLUTIONS

LINTHICUM, Md. — February 19, 2004 — CIENA® Corporation (NASDAQ: CIEN), a leading global provider of innovative network solutions, today announced a definitive agreement under which CIENA will acquire privately held Internet Photonics, Inc. With offices in Shrewsbury, N.J. and Marlborough, Mass., Internet Photonics is a leading supplier of carrier-grade optical Ethernet transport and switching solutions.

“At a time when carriers are keenly focused on next-generation broadband service delivery, the acquisition of Internet Photonics expands CIENA’s solution portfolio targeting multiservice operators and traditional carriers with the addition of a flexible platform for carrier-grade Gigabit Ethernet solutions,” said Gary Smith, CIENA’s president and CEO.

“In the cable market, optical Ethernet is the underlying infrastructure for the new ‘triple-play’ of bundled services, as well as video-on-demand, voice-over-IP and HDTV. It also improves the access speeds of existing services like cable modem Internet access,” Smith said. “This same carrier-class Ethernet switching and transport infrastructure also can help traditional telecom carriers provide new high-speed Ethernet services faster and at lower cost.”

“When combined with CIENA’s global reach, financial strength and current solution set, Internet Photonics’ leading broadband solutions become even more compelling and comprehensive,” said Gregory Koss, president and CEO of Internet Photonics. “In addition to the current product and customer

synergies, we also see the potential to apply Internet Photonics’ flexible, low-cost transport infrastructure to enhance CIENA’s current metropolitan and enterprise solutions.”

Internet Photonics’ customers include six of the top ten cable operators in the U.S., including significant deployments by Cablevision and Adelphia, as well as carriers such as TDS Metrocom, who use Internet Photonics’ solutions to deploy Ethernet private-line services.

The Optical Ethernet Market
Industry analyst Infonetics Research estimates the worldwide Ethernet services market in which Internet Photonics participates will grow from approximately $2.9 billion in 2003 to $7.5 billion by 2007.

“Internet Photonics’ approach gives low capital and operational costs to carriers and cable operators, as well as a rapid return on investment even on minimal service take rates,” said Michael Howard, principal analyst at Infonetics Research. “As a result, Internet Photonics has several major operators as customers. Internet Photonics’ initial success in the growing cable transport market gives CIENA a new and attractive customer set, and CIENA’s market presence, sales channel, and global support should enhance Internet Photonics’ momentum.”

Internet Photonics’ Product Overview

Access
LightStack MXA is a low-cost access device deployed at the customer premise or local CO/hub providing a managed demarcation point between the operator network and the customer and delivering Ethernet and/or SONET/SDH services.

LightStack MX is an aggregation node that resides at the customer premise, hub, head-end, or central office and provides multiplexing of up to 8 GbE onto 10GigE wavelengths in a single stackable 1.75” high unit.

Aggregation
LightStack GSLAM integrates optical transport, access service aggregation, switching, and add/drop multiplexing functionality. It connects with the MXA and MX making it an ideal means to collect, aggregate, and switch access circuits. The platform’s ability to crossconnect 64 Gigabit Ethernet connections provides port scalability and bandwidth capacity needed to support major cable headends or carrier COs.

Transport
LightHandler is a 40 wavelength passive optical add/drop and bi-directional optical amplifier that interfaces into existing SONET/SDH and DWDM networks to flexibly scale services capacity.

Management
LightStack NCS offers a carrier-grade network configuration and service monitoring NMS. Its ability to simplify the tasks of network service provisioning, fault isolation, and performance monitoring makes it a powerful tool for enabling cable operators and carriers to profitably offer new Ethernet based services.

Transaction Terms and Timing
Under the terms of the acquisition agreement, Internet Photonics will merge into CIENA, and all the outstanding shares of Internet Photonics common and preferred stock, and employee stock options will be exchanged for shares of CIENA common stock. Based on the average closing price of CIENA common stock for the ten trading days prior to the signing of the merger agreement, the number of CIENA shares to be issued is 24.4 million, and the value of the transaction is approximately $150 million. Internet Photonics’ employee stock options will be converted into options to purchase CIENA shares.

CIENA expects the transaction to qualify as a tax-free reorganization. This transaction is subject to various conditions and approval by appropriate government agencies. The boards of directors of both CIENA and Internet Photonics, and a majority of the Internet Photonics’ shareholders have approved the transaction. It is expected that this transaction will close by the end of CIENA’s third fiscal quarter 2004. For accounting purposes, the value of the transaction will be determined using a five-day average of CIENA’s common stock’s closing price beginning on February 17, 2004.

Following completion of the transaction, Internet Photonics will become part of CIENA’s Metro and Enterprise Solutions group and will continue to operate from its Shrewsbury, N.J. and Marlborough, Mass. locations.

Morgan Stanley served as financial advisor to CIENA on this transaction. CSFB served as financial advisor to Internet Photonics.

Live Conference Call/Web Broadcast
Separately today, CIENA also announced its intent to acquire Catena Networks, Inc., as well as results for its fiscal first quarter. In conjunction with these announcements, CIENA will host a discussion with investors and financial analysts today, Thursday, February 19, 2004 at 8:30 a.m. (Eastern).
