Note from Mike Pacilio to all Exelon Nuclear employees

Dear Colleagues:

By now, you’ve likely seen the news that Exelon has agreed to merge with Constellation Energy Group. This is an exciting development for Exelon and for Exelon Nuclear; it offers a platform for future growth for our company and expands our nuclear fleet.

After the merger, CENG will remain largely as it is today, as a separate operating group for its three nuclear stations – Calvert Cliffs in Maryland, Nine Mile Point and Ginna in New York. All of these well-run PWRs and BWRs have successfully extended their licenses. They will continue to operate as Constellation Energy Nuclear Group LLC.

The addition of CENG fleet of five operating reactors will solidify Exelon’s place as the largest, most efficient nuclear company in America. We have long-standing and positive working relationships with CENG and its partner, the French utility Électricité de France (EDF), the largest nuclear operator in the world. So the merger promises to bring Exelon Nuclear new, productive associations.

As part of the merger, Exelon Nuclear headquarters will officially shift from Cantera to Kennett Square. Cantera will continue in its role as the Midwest Headquarters of Exelon Nuclear. The transition will take place over a number of years, and I expect that we will manage it fully through reassigned open positions, normal attrition and voluntary relocations. Eventually, we expect about 100 Cantera positions to be reassigned. The merger will have virtually no impact on the operating sites.

More information will be shared on a regular basis as we move through the transition, but at the forefront I want to reassure you of a few things we know for certain:

•

This will be a positive change for Nuclear – We’re merging with a good company that fits well with Exelon Nuclear’s strategic direction. CENG is a strong player in the nuclear industry with talented employees and a competitive business model, very much like Exelon Nuclear. EDF is a major force in the world nuclear industry and we will learn from their experience.

•

The transition will take time – Exelon will not close on the transaction until the first quarter of 2012. It could take another year beyond that for us to fully understand what position reassignments are appropriate.

•

We need to stay focused on our mission – This change will be exciting for all of us. Some of you may be asked to provide assistance as we work through the transition. But we absolutely must stay focused on our goal of being the safest, most efficient nuclear operation in America – by paying unconditional attention to our tasks, nuclear safety and the safety of our fellow workers.

We will be working through details in the coming months, and I commit to keeping you informed throughout that process. In the meantime, your feedback is important. So make sure you ask questions, preferably directed to your supervisors, and we will make sure answers are forthcoming.

Thank you for your continued focus on Exelon Nuclear’s success.

Sincerely,

Mike
