Distribution: Senior Leaders and Managers

Dear Colleagues:

Earlier this morning, FIS issued a news release announcing that we have signed a definitive agreement to acquire SunGard, a financial services leader in banking, capital markets and asset management solutions. This is a tremendous milestone bringing together two great technology companies with similar business models, complementary solution portfolios and highly talented employees that are dedicated to serving the financial services industry. Combined, our focus will be on servicing global, regional and community financial institutions as well as private equity, asset managers and insurance companies.

Through this combination, FIS will be uniquely positioned to offer clients a broad range of solutions for enterprise banking, capital markets, asset management, risk and compliance, treasury and insurance. SunGard’s solutions portfolio is very complementary to our existing offerings. After the close, the addition of SunGard will bring new solutions and services that will enhance our current offerings including treasury, risk management, asset management, derivatives, trading and insurance.

The combined company will be headquartered in Jacksonville, Fla. and I will serve as president and CEO. We will operate under the FIS name.

This is the most significant announcement we have made since our acquisition of Metavante in 2009 and we expect it to create interest and excitement in the industry, with our clients and amongst our employees. As leaders within our organization, we want to make sure you are well prepared to address questions today and in the weeks to come.

Attached is the communications package we have prepared to help you facilitate these conversations. This package includes:

In addition to these materials, I encourage you to attend a conference call at 12:30 p.m. ET today whereby I will share with you the strategic rationale behind this acquisition and your role in communicating it to your clients and employees. A calendar invite with the teleconference details will be sent to you this morning. If you do not receive an invitation, you can contact fis.corporate.communications@fisglobal.com to request the dial in details.

When you have conversations about this announcement, you must adhere to the messaging provided in this package. Communicating anything outside the approved messaging may be considered gun jumping, which could delay the closing of the transaction.

It is also important to remember that we have signed an agreement to acquire SunGard and that the transaction is not yet closed. The acquisition is subject to regulatory approvals and contractual closing conditions. We expect to close during the fourth quarter. Until then, we will continue to operate as separate companies and it is business as usual for both organizations. You should not reach out to anyone at SunGard unless you are specifically requested to do so.

Most importantly, we must remain focused on serving the needs of our clients. As leaders within the organization, I need your help in keeping our employees laser focused on the business at hand and delivering third and fourth quarter results. We cannot allow our sales momentum to slow nor can we allow ourselves to be distracted by this exciting combination.

I am privileged to lead what I truly believe to be the greatest company in our industry. Because of you and the hard work of your teams to drive our clients’ business forward each and every day, we are well positioned to take this significant step in empowering the financial world. Thank you for making this possible.

Regards,
