Ciena® Corporation (NASDAQ: CIEN), the network specialist, today announced that it has entered into agreements with Nortel to purchase substantially all of the optical networking and carrier Ethernet assets of Nortel’s Metro Ethernet Networks (MEN) business for $390 million in cash and 10 million shares of Ciena common stock. The product and technology assets to be acquired include Nortel’s long-haul optical transport portfolio; metro optical Ethernet switching and transport solutions; Ethernet transport, aggregation and switching technology; multiservice SONET/SDH product families; and network management software products.

The proposed transaction would strengthen Ciena’s global presence and bring together complementary technologies in switching and transport that will offer customers a practical path for transitioning to automated, optical Ethernet-based networking. Based on the closing price of Ciena’s stock on Tuesday, October 6, 2009, the aggregate value of the shares to be issued by Ciena is approximately $131 million, bringing the value of the consideration to approximately $521 million. The assets to be acquired generated approximately $1.36 billion in revenue for Nortel in 2008 and $556 million (unaudited) in the first six months of 2009.

“This is a unique and exciting opportunity for us to accelerate our existing strategy and the pace of our growth plans by two to three years,” said Gary Smith, Ciena’s CEO and president. “We believe this transaction will position us for faster growth by giving us greater geographic reach, broader customer relationships and a deeper portfolio of solutions. We believe we are best positioned to leverage these assets, thereby creating a significant challenger to traditional network vendors.”

He continued: “We have tremendous respect for the talented people at Nortel and for their track record of innovation, and we look forward to the opportunity to build on our existing presence in Canada, where we have operated an R&D center of excellence since 2003. Should the transaction be completed, we will be disciplined in integrating the acquired assets on an aggressive timeframe. We will draw from the best in our respective organizations, cultures and expertise to ensure that we deliver continuity of supply and innovation for our customers and meet shareholder expectations.”

Ciena is expected to make employment offers to at least 2,000 Nortel employees to become part of Ciena’s global team of network specialists. The proposed acquisition would significantly enhance Ciena’s existing Canadian-based development resources, making Ottawa the company’s largest product and development center. Ciena currently has development facilities in Alpharetta, Georgia; Linthicum, Maryland; Ottawa, Ontario; San Jose, California; Spokane, Washington; and Gurgaon, India. As of July 31, 2009, the end of its fiscal third quarter, Ciena employed 2,110 employees globally.

Given the structure of the transaction as an asset carve-out, Ciena expects to incur integration-related costs of approximately $180 million. Based on current expectations of deal timing, Ciena anticipates that the majority of the integration-related costs will be incurred in 2010 and expects the transaction to be significantly accretive to Ciena’s results of operations in fiscal 2011.

As a result of Nortel’s restructuring process, the transaction is subject to a competitive bidding process and requires the approval of the United States Bankruptcy Court for the District of Delaware and the Ontario Superior Court of Justice. Ciena expects hearings before those courts to approve bidding procedures, break-up fee and expense reimbursement will be held within the next several weeks, followed by a bid period and a potential auction, with final sale hearings to be held thereafter.

In the Europe, Middle East and Africa (EMEA) region, Ciena has entered into an agreement with the Joint Administrators, on behalf of the Nortel EMEA entities participating in the transaction for which they have been appointed, and where applicable, the transaction is subject to statutory information-sharing and consultation processes with the relevant employee representatives, as well as approval of the court in Israel.

The transaction is also subject to customary closing conditions, including receipt of necessary regulatory approvals.

Deutsche Bank Securities Inc. and Foros Securities LLC served as financial advisors to Ciena on this transaction.

Additional information about this proposed transaction is available in a Form 8-K to be filed by Ciena today and on Ciena’s website at http://www.ciena.com.
