RCN Metro Optical Networks Re-launches as Sidera Networks

New York, NY, September 9, 2010 – RCN Metro Optical Networks, a premier provider of fiber optic-based network solutions, today announced that it will re-launch as Sidera Networks.  The re-launch follows the completion of the acquisition of RCN Corporation by private investment fund ABRY Partners, LLC.  In addition, the Company announced the appointment of Michael Sicoli as Chief Executive Officer of Sidera Networks.

Sidera is Latin for a constellation of stars, which is embodied in the Company’s employees, service capabilities, network, and customer base.  Sidera Networks will build upon the solid foundation that RCN Metro created and continue its commitment to be the premier provider of high-capacity transport services for carriers as well as large and medium sized businesses, offering a comprehensive suite of industry-leading services including Ethernet, SONET, Wavelength, Video Transport, Internet, Dark Fiber solutions and more.

“The name Sidera has strong links to the Company’s history and cultural values, and it represents the next evolutionary stage for our business,” said Michael Sicoli, CEO, Sidera Networks.  “As a team, Sidera has one simple goal and that is to provide outstanding service and support to our customers. I am excited to lead this all-star team through its next phase of growth.”

Prior to this role, Mr. Sicoli served as Executive Vice President and Chief Financial Officer for RCN Corporation from 2005–2010, where he played a lead role in establishing and executing the company’s strategy including the transaction to take RCN private in 2010.  Prior to joining RCN, Mr. Sicoli worked for Nextel, Deloitte Consulting and Accenture. Mr. Sicoli holds an M.B.A. from The University of Virginia, Darden Graduate School of Business Administration, and a B.A. in Economics from The College of William and Mary.

In addition, Ed O’Hara will join Sidera Networks as the CFO.  The rest of the Sidera Networks leadership team will remain the same, including Felipe Alvarez, President and COO, Paul Eskildsen, General Counsel, Patrick O’Hare, VP Engineering and Operations, and Maura Mahoney, VP Sales and Marketing.

“This is an exciting new chapter in our Company’s history,” said Felipe Alvarez, President, Sidera Networks. “Being privately held and fully separate from RCN’s legacy cable business will allow us to focus all of our energy and resources on growing the business.”

Sidera Networks will showcase its suite of services at the COMPTEL Plus Fall 2010 Show, September 12-14, 2010, in Dallas, TX at booth #501.
