The following is the transcript of a video by Anthony J. Alexander, President and Chief Executive Officer of FirstEnergy, which was first broadcast to FirstEnergy employees on February 11, 2010.

Good morning.

These are exciting times for our Company.

This morning, we announced that we have reached an agreement to merge with Allegheny Energy, an organization that, like us, has a long and proud tradition of generating and delivering electric service to customers, safely and reliably.

The new company – which will keep the FirstEnergy name and remain headquartered in Akron – will be the largest investor-owned electric system in the country based on serving more than six million customers. We’ll have over 24,000 MW of generating capacity, and about $16 billion in annual revenues, based on 2009 results.

It’s because of the efforts of all FirstEnergy employees that we can enter into this transaction and take our company to the next level.

The fact is… I’m very excited about the opportunities and potential that this transaction creates.

We will be a stronger, more flexible regional energy provider.

We’ll increase our generating capability seventy percent…more than doubling our supercritical coal-fired generation, and adding over 1,000 MWs of pumped storage.

Our combined generation fleet will have a mix of resources, including nuclear, coal, natural gas and pumped storage, making us one of the nation’s largest and most diversified fleets.

And this larger fleet will provide our retail sales and marketing organization enhanced opportunities and flexibility.

We’ll also gain strong distribution utilities in an adjacent geographic footprint that complements our distribution service area.

We’ll have a growing transmission business.

And our adjacent operations will make the sharing of best practices and mutual support more efficient and effective.

It will take 12-14 months before this merger can be finalized. During that time, our organizations will have to complete many steps, including gaining approval by shareholders and from various state and federal regulators.

The plan is to have employee teams from both companies working together on integration issues that are part of every merger. And we’ll share more details on the teams when plans are finalized.

But let me add something important here: We all know that mergers have impacts on the workforce. And given the current economic conditions, we understand the increased concerns employees will have during this period.

While it’s really too early to predict what will happen, we intend to work closely with regulators to develop plans that will allow this merger to proceed quickly, with as little negative affect as possible on employees.

And while we don’t have the answers yet, it appears that this merger will have little or no impact on craft employee levels.

And to help mitigate the impact on the rest of the workforce, we’ll slow down our hiring at FirstEnergy to make as many opportunities as possible available for Allegheny employees. The fact of the matter is, we will need a lot of talented people to run our new company.

Today there will be an Employee Update that provides additional information. We will also provide updates as they become available.

While this is good and exciting news, we must stay focused and not allow this to become a distraction. This will take some time to complete and until then, we must operate as separate companies. Meanwhile, continue to focus on working safely everyday and on the fundamentals of our business and your job.

There is no doubt that this past year has been difficult. But I have a lot of confidence in you. You’ve delivered on every challenge we’ve ever faced. You’ve adjusted to the new operating realities and have enhanced our operations regardless of circumstances – improving in many key measures. Your leadership, character, skills and ability to focus on the fundamentals of our business will be critical for the exciting, but challenging times ahead of us.

This is a significant move for both companies. I’m looking forward to what we can do together.

Thank you for your support.
