The following is an email to all employees of Internet Photonics, Inc.
from Gary B. Smith, President and CEO of CIENA Corporation

To All Employees of Internet Photonics:

I am very excited to be writing you today to welcome you to the CIENA team.

You are joining CIENA at an exciting time in our history, and you will play an important role as CIENA transforms into a major, global provider of network solutions for the delivery of any broadband service anywhere.

We believe that CIENA’s market presence, financial stability and established relationships will add to the credibility and traction of solutions from both IPI and Catena so that together we may maximize opportunities for growth and long-term success. We think this unified company is a powerful, complementary combination in terms of network solutions, customer bases, sales forces and incredible potential.

I know you will have a lot of questions, and I will do my best to answer them. I invite you to attend a teleconference call with me today at
1 p.m. During the call, Jim Hjartarson, president and CEO of Catena, Greg Koss, and I will talk about why we think this is such a strong combination. Then we’ll open the call to your questions. In addition, members of CIENA’s team will soon be visiting your offices to talk with you in person and answer additional questions.

In the meantime, on behalf of all CIENA employees worldwide, I am thrilled to welcome you to the CIENA team. I hope you are as excited as I am about this combination and the enhanced opportunities for our respective companies.

Gary
