On December 4, 2008, The PNC Financial Services Group, Inc. circulated the following letter from James E. Rohr, Chairman and Chief Executive Officer of PNC, to its employees. The letter was also sent to National City Corporation for distribution to its employees:

December 4, 2008

Upon completing the acquisition of National City at the end of this month we will become the nation’s 5th-largest banking franchise by deposits. In addition, we will maintain solid capital and liquidity levels. I am confident that this strength, scale and position will provide us with a tremendous opportunity to build a great company and make a lasting difference for everyone we serve – our customers, employees, shareholders and communities.

Ongoing interactions with our colleagues at National City have served to increase the excitement around what, together, we can achieve. Our shared values and intense focus on meeting or exceeding customer expectations make PNC and National City a good fit. Now, we must execute. To that end, the integration team – consisting of talented leaders from both organizations – has started to collaborate on a comprehensive conversion plan. Bringing together two organizations our size requires considerable work. We must prepare to make the conversion as easy as possible for customers and employees. At the same time, we must eliminate redundancies to create greater efficiency.

I am certain that the outstanding employees in both organizations have the ability to serve customers, complete the integration and position the new PNC for long-term success. Just as important, I believe we have an executive team that is ready to lead the combined organization after the closing, which is scheduled for December 31, 2008, pending shareholder, regulatory and other appropriate approvals. Working together, these leaders, all of whom will report directly to me, will implement a business model that emphasizes customer satisfaction, risk management, teamwork and growth.

Our businesses will be led by:

Tom Whitford will relocate to Cleveland and lead the integration of National City into PNC.

As previously announced, National City’s Shelley Seifert and Jon Gorney will help lead the transition of employees, systems and technology to PNC, reporting to Tom and Tim, respectively.

Market leadership – including responsibility for sales and revenue growth priorities in corporate banking, commercial banking and wealth management within their core geographic regions – will be provided by:

Key staff and support areas will be headed by:

Of course, this is just the beginning. In the coming months, these executives will announce organizational structures for their areas that will include extremely talented leaders from both National City and PNC.

A number of significant core strengths – an experienced leadership team, talented and committed employees, an intense focus on our customers and a values-based culture – will only become stronger as a result of joining forces with National City. I appreciate your contributions to the progress we have made and for what we will accomplish – together.

Sincerely,

James E. Rohr

Chairman and Chief Executive Officer
